Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

With the development of display technology, the size of the display equipment is larger and larger, and huge visual impact is brought to a user, so that the use experience of the user is improved. In terms of Display principle, the displayable screen of the Display device may be an LED (Light Emitting Diode, abbreviated as LED) Display screen, an OLED (Organic Light-Emitting Diode, abbreviated as OLED) Display screen, or an LCD (Liquid Crystal Display, abbreviated as LCD) Display screen, and of course, other Display screens may be selected according to actual situations. Functionally, the display device may be a common television, computer, removable display device, or tiled display device, but is not limited thereto.

As the size of display devices increases, the weight of display devices also increases. If the frame of the display device is an integrated frame, the weight of the display device is increased to a certain degree, the deformation degree of the gravity center position of the frame of the display device is larger, and the deformation degrees of other positions are smaller, so that the strength of the frame of the display device is required to be higher and higher along with the increase of the size of the display device.

An embodiment of the utility model provides a locking mechanical system. The locking mechanism can be applied to structural members needing to be connected and is not limited to the frame of the display device. As shown in fig. 1 and 2, the locking mechanism 1 includes a connecting assembly 11 and a first locking assembly 12. The connecting assembly 11 comprises at least a connecting rod 111. The connecting rod 111 is provided with a first limiting hole 110. The first limiting hole 110 may be a through hole or a blind hole. The first locking assembly 12 includes a first positioning member 121 and a second positioning member 122. The first positioning member 121 has a locking through hole 120 for locking with the second positioning member 122. The second positioning member 122 has a free end and a limit end.

When the locking mechanism 1 shown in fig. 1 and 2 is in the locked state, the first positioning element 121 included in the first locking component 12 is sleeved on the connecting rod 111, and the locking through hole 120 of the first positioning element 121 included in the first locking component 12 is communicated with the first limiting hole 110. The first locking component 12 includes a second positioning member 122 having a position-limiting end that is engaged with the first position-limiting hole 110.

The locking process of the locking mechanism will now be described by way of example with reference to the locking mechanism 1 shown in fig. 1 and 2 locking two profile sections. The two profile sections are defined below as a first profile section 21 and a second profile section 22 as shown in fig. 5. The section extending direction of the first section bar 21 and the section extending direction of the second section bar 22 may be a straight section extending direction, a broken line section extending direction, an arc section extending direction, or a wavy section extending direction. The description will be given taking as an example that the segment extending direction of the first profile segment 21 and the segment extending direction of the second profile segment 22 are linear segment extending directions.

The first step is as follows: as shown in fig. 5, the connecting rod 111 is arranged on the first profile section 21, and the connecting rod 111 is ensured to extend out of the first profile section 21 at the connecting end surface of the first profile section 21 (the connecting end surface of the first profile section 21 is perpendicular to the section extending direction of the first profile section 21); the first positioning element 121 included in the first locking element 12 shown in fig. 2 is arranged at a position of the second profile section 22 close to the connecting end surface of the second profile section 22 (the connecting end surface of the second profile section 22 is perpendicular to the section extending direction of the second profile section 22). It should be understood that the connection end face of the first profile section 21 refers to the end face of the first profile section 21 that is close to the second profile section 22 when the first profile section 21 is connected to the second profile section 22. Similarly, the connection end surface of the second profile segment 22 means that when the second profile segment 22 is connected with the first profile segment 21, the second profile segment 22 is close to the end surface of the first profile segment 21.

The second step is that: as shown in fig. 5, the end of the connecting rod 111 extending out of the connecting end surface of the first profile section 21 extends into the second profile section 22 from the connecting end surface of the second profile section 22 (the extending direction is the direction of the first arrow a shown in fig. 5), and it is ensured that the first positioning element 121 included in the first locking component 12 shown in fig. 2 is sleeved on the end of the connecting rod 111 extending into the second profile section 22, so that the locking through hole 120 of the first positioning element 121 included in the first locking component 12 shown in fig. 2 is communicated with the first limiting hole 110. It should be understood that in order to ensure that the first positioning element 121 of the first locking assembly 12 shown in fig. 2 has a locking through hole 120 communicating with the first limiting hole 110, the first limiting hole 110 formed by the connecting rod 111 should be located at the region where the connecting rod 111 extends out of the connecting end surface of the first profile segment 21.

The third step: the position-limiting end of the second positioning element 122 included in the first locking component 12 shown in fig. 2 extends into the locking through hole 120 included in the first positioning element 121 included in the first locking component 12, and then the position-limiting end of the second positioning element 122 included in the first locking component 12 shown in fig. 2 is clamped in the first position-limiting hole 110, so that the end, extending out of the connecting end surface of the first profile section 21, of the connecting rod 111 provided in the first profile section 21 is ensured to be locked in the second profile section 22 by the first locking component 12 shown in fig. 2.

It will be appreciated that the distance between the first positioning element 121 comprised by the first locking element 12 and the connecting end surface of the second profile segment 22 can be adjusted to control the distance between the connecting end surface of the first profile segment 21 and the connecting end surface of the second profile segment 22 as the case may be, as shown in fig. 2 and 5. For example: when the first locking element 12 comprises a first positioning element 121 at a relatively large distance from the connecting end face of the second profile section 22, the distance between the connecting end face of the first profile section 21 and the connecting end face of the second profile section 22 is relatively small. When the first locking element 12 comprises a first positioning element 121 which is spaced apart from the connecting end face of the second profile section 22 by a relatively small distance, the first profile section 21 is spaced apart from the connecting end face of the second profile section 22 by a relatively large distance. However, the distance between the first positioning element 121 comprised by the first locking element 12 and the connecting end face of the second profile section 22 is limited by two factors: the first factor is: the extension of the connecting rod 111 beyond the connecting end face of the first profile section 21; the second factor is: the connecting rod 111 is provided with a first limiting hole 110.

As shown in fig. 1, fig. 2 and fig. 5, according to the structure and the locking process of the locking mechanism 1 provided by the embodiment of the present invention, since the first locking component 12 includes the first positioning element 121 having the locking through hole 120 for locking with the second positioning element 122, when the locking mechanism 1 is in the locked state, the position-limiting end of the second positioning element 122 included in the first locking component 12 is clamped in the first position-limiting hole 110, so that the first locking component 12 and the connecting component 11 are fixed together. Based on this, one end of the connecting rod 111 can be clamped in one section of the section (the first section 21), the first positioning element 121 is arranged in the other section of the section (the second section 22), and then the first positioning element 121 is sleeved on one end of the connecting rod 111 extending out of the first section 21; when the locking mechanism 1 is in the locked state, the first positioning element 121 of the first locking element 12 is sleeved on the connecting rod 111, and the locking through hole 120 of the first positioning element 121 of the first locking element 12 is communicated with the first limiting hole 110, so that the limiting end of the second positioning element 122 of the first locking element 12 can be clamped in the first limiting hole 110 through the locking through hole 120, and the detachable connection of the first profile section 21 and the second profile section 22 is realized. Therefore, the embodiment of the utility model provides a locking mechanical system 1 can realize the connection of dismantling of two sections section bars for when dismantling the section bar and being applied to the display device frame, guarantee that the display device frame can dismantle, and then reduce the frame deformation degree of display device when the display device is bigger. In addition, the embodiment of the present invention provides a second positioning element 122 that the first locking component 12 included in the locking mechanism 1 includes is blocked into the first limiting hole 110 that the connecting rod 111 included in the connecting component 11 includes is opened, therefore, the embodiment of the present invention provides a locking mechanism 1 that can simply connect two profile sections together, thereby simplifying the connection process of the two profile sections. It should be understood that the material or strength of each sub-section segment included in the frame of the display device can be adjusted to ensure that the frame of the display device has certain strength, so that the deformation degree of the frame of the display device when the display device is relatively large is reduced.

In some possible implementations, as shown in fig. 1 and fig. 2, when the locking mechanism 1 is in the locked state, the first positioning element 121 included in the first locking component 12 is sleeved on the connecting rod 111, and the locking through hole 120 of the first positioning element 121 included in the first locking component 12 is communicated with the first limiting hole 110, so when the locking mechanism 1 is in the locked state, the first limiting hole 110 may be located in the locking through hole 120 to ensure that the first limiting hole 110 is located in the locking through hole 120, so as to ensure that the limiting end of the second positioning element 122 included in the first locking component 12 can be clamped into the first limiting hole 110 after extending into the locking through hole 120.

In some possible implementations, as shown in fig. 2, in order to ensure that the second positioning element 122 included in the first locking assembly 12 can be accurately inserted into the first limiting hole 110, the connecting assembly 11 further includes a first limiting spring 112 in a compressed state when the locking mechanism 1 is in a locked state, and the first limiting spring 112 is sleeved on the connecting rod 111. The first limiting spring 112 includes a fixed end and an opposite end. The fixed end of the first limit spring 112 is clamped on the connecting rod 111. When the locking mechanism 1 is in the locked state, the abutting end of the first limiting spring 112 abuts against the outer surface of the first positioning element 121 included in the first locking component 12. Because the first limiting spring 112 is in a compressed state when the locking mechanism 1 is in the locked state, when the first positioning element 121 is sleeved on the connecting rod 111, the first limiting spring 112 can ensure that the first positioning element 121 included in the first locking component 12 cannot pass through the first limiting hole 110, so that the locking through hole 120 of the first positioning element 121 included in the first locking component 12 is aligned with the limiting hole accurately, and the assembly process of the connecting component 11 and the first locking component 12 is simplified.

Specifically, as shown in fig. 5, the first profile section 21 is located on the left side of fig. 5, and the second profile section 22 is located on the right side of fig. 5. When one end of the connecting rod 111 is arranged on the first profile section 21, the first limiting spring 112 is sleeved on the connecting rod 111. The first locking assembly 12 shown in fig. 2 includes a first locator element 121 disposed within the second profile section 22.

As shown in fig. 1, 2 and 5, when the second profile section 22 is kept stationary, the first profile section 21 is moved toward the second profile section 22 in the first arrow direction a shown in fig. 5 so that the contact end surface of the first profile section 21 comes closer to the contact end surface of the second profile section 22. In this process, when the end of the connecting rod 111 that extends out of the first profile section 21 has not yet extended into the first profile section 21, the first limit spring 112 is in a free state; when the end of the connecting rod 111 extending out of the first section 21 extends into the second section 22, and the first positioning element 121 included in the first locking component 12 is gradually sleeved on the area where the connecting rod 111 extends into the second section 22. It should be understood that in order to ensure that in the locked state, the abutting end of the first limit spring 112 abuts the outer surface of the first positioning element 121 comprised by the first locking assembly 12, the first limit spring 112 should be able to enter the second profile section 22.

As shown in fig. 1, fig. 2 and fig. 5, when the outer surface of the first positioning element 121 included in the first locking component 12 does not contact with the abutting end sleeved on the first limiting spring 112, or the outer surface of the first positioning element 121 included in the first locking component 12 contacts with the abutting end of the first limiting spring 112, but does not compress the abutting end of the first limiting spring 112. In this case, the first limit spring 112 is still in a free state. Since the first limit spring 112 is in a compressed state when the locking mechanism 1 is in a locked state, when the first limit spring 112 is in a free state (a state of not being compressed), a part or even all of the first limit hole 110 is shielded by the first limit spring 112, so that the first positioning member 121 included in the first locking assembly 12 can be located at the right side of the position of the first limit hole 110 opened by the connecting rod 111 in fig. 2 under the blocking of the first limit spring 112. When the first limiting spring 112 is in a free state, the first positioning element 121 included in the first locking assembly 12 may be located at the right side of the position of the first limiting hole 110 opened by the connecting rod 111 in fig. 2 under the block of the first limiting spring 112. When the second positioning member 122 of the first locking component 12 enters the corresponding locking through hole 120 of the first positioning member 121, the first positioning member 121 of the first locking component 12 is manually or otherwise moved in the direction of the second arrow B shown in fig. 5 (i.e., in the right direction of fig. 2) relative to the connecting rod 111.

As shown in fig. 1, fig. 2, and fig. 5, when the first positioning element 121 included in the first locking assembly 12 moves in the direction of the second arrow B shown in fig. 5 relative to the connecting rod 111, it can be effectively ensured that the connection between the locking through hole 120 formed in the first positioning element 121 included in the first locking assembly 12 and the first limiting hole 110 is better when the first positioning element 121 included in the first locking assembly 12 gradually presses the abutting end of the first limiting spring 112, so as to ensure that the limiting end of the second positioning element 122 included in the first locking assembly 12 is accurately clamped into the first limiting hole 110 through the locking through hole 120 formed in the corresponding first positioning element 121.

In some possible implementations, as shown in fig. 2 and 3, the radial length of the first limiting hole 110 gradually decreases along the increasing direction of the hole depth of the first limiting hole 110. The radial length of the limiting end surface 1221 of the second positioning element 122 included in the first locking component 12 gradually decreases along the increasing direction of the hole depth of the first limiting hole 110. Therefore, when the position-limiting end of the second positioning element 122 included in the first locking assembly 12 is located in the first position-limiting hole 110, if the second positioning element 122 included in the first locking assembly 12 is not locked yet, the position-limiting end of the second positioning element 122 included in the first locking assembly 12 can also advance along the hole depth increasing direction of the first position-limiting hole 110. During the advancing process, the limiting end surface 1221 of the second positioning element 122 included in the first locking assembly 12 applies a downward force F0 to the hole wall of the first limiting hole 110. Accordingly, the hole wall of the first limiting hole 110 applies an upward reaction force F to the limiting end face 1221 of the second positioning element 122 included in the first locking component 12. When the position-limiting end of the second position-limiting member 122 included in the first locking assembly 12 initially extends into the first position-limiting hole 110, the position-limiting end face 1221 of the second position-limiting member 122 included in the first locking assembly 12 substantially contacts with the wall of the right hole of the first position-limiting hole 110 shown in fig. 3, so that when the hole wall of the first position-limiting hole 110 applies an upward reaction force F to the position-limiting end face 1221 of the second position-limiting member 122 included in the first locking assembly 12, the direction of the reaction force F points to the upper left of fig. 3. The reaction force F has component forces in both the horizontal direction and the vertical direction. It should be understood that the horizontal direction is parallel to the axial direction of the connecting rod 111 here, and the vertical direction is perpendicular to the axial direction of the connecting rod 111.

Fig. 4 shows an exploded view of the reaction force received by the end face of the position-limiting end of the second positioning element included in the first locking assembly. Fx is a component force in the horizontal direction, and the direction thereof is directed to the right side of the figure. Fy is a component force in the vertical direction, and the direction thereof is directed to the upper side of the figure. The angle between the reaction force F and the horizontal direction is set to θ, where Fx is Fcos θ and Fy is Fsin θ. As can be seen from fig. 1 to 4, when the first locking component 12 includes the reaction force F received by the limiting end surface 1221 of the second positioning member 122, the second positioning member 122 included in the first locking component 12 will move to the left in fig. 3 under the action of the reaction force F. The first positioning member 121 of the first locking assembly 12 is moved to the left in fig. 3 along the axial direction of the connecting rod 111 by the second positioning member 122 of the first locking assembly 12. When the second positioning element 122 of the first locking assembly 12 is locked with the corresponding locking through hole 120 of the first positioning element 121, the position-limiting end of the second positioning element 122 of the first locking assembly 12 cannot move to the first position-limiting hole 110 continuously along the depth increasing direction of the first position-limiting hole 110, so that the position-limiting end of the second positioning element 122 of the first locking assembly 12 is clamped in the first position-limiting hole 110.

As shown in fig. 1 to 4, when the limiting end of the second positioning element 122 moves towards the hole depth increasing direction of the first limiting hole 110, the hole wall of the first limiting hole 110 can apply a certain reaction force F to the limiting end of the second positioning element 122, so as to drive the first positioning element 121 and the first limiting hole 110 formed on the connecting rod 111 to move relatively, so that in the process of locking the first positioning element 121 and the locking through hole 120, the first limiting hole 110 and the locking through hole 120 are assisted to be aligned gradually, so that the limiting end of the second positioning element 122 can enter the first limiting hole 110 to the maximum extent, and the connection reliability between the connection assembly 11 and the first locking assembly 12 is ensured.

For example, as shown in fig. 1 to 4, when the radial length of the first position-limiting hole 110 gradually decreases along the increasing direction of the hole depth of the first position-limiting hole 110, the radial length of the position-limiting end surface 1221 of the second position-limiting member 122 included in the first locking component 12 gradually decreases along the increasing direction of the hole depth of the first position-limiting hole 110, and the first position-limiting hole 110 is a tapered hole, but is not limited thereto, as long as the requirement on the radial length of the first position-limiting hole 110 is satisfied. The limiting end of the second positioning element 122 is a tapered limiting end, but is not limited thereto, as long as the requirement of the radial length of the limiting end surface 1221 of the second positioning element 122 included in the first locking component 12 is satisfied.

As shown in fig. 1 to 4, when the first positioning member 110 is a conical hole and the positioning end surface of the second positioning member 122 is a conical positioning end surface, the included angle α between the height of the conical hole and the generatrix of the conical hole is substantially equal to the included angle between the reaction force F and the horizontal direction, and therefore, the included angle between the height of the conical hole and the generatrix of the conical hole determines the magnitude of the horizontal component Fx of the reaction force F. Since Fx is Fcos θ, the smaller the angle between the height of the conical hole and the generatrix of the conical hole, the more advantageous the first locking element 12 can be moved to the left in fig. 2. In addition, when the limiting end of the second positioning element 122 included in the first locking assembly 12 is clamped in the conical hole, the axial direction of the conical hole may coincide with the axial line of the conical limiting end face, or may not coincide with the axial line of the conical limiting end face.

In some possible implementations, as shown in fig. 1 to 5, in order to facilitate the detachment of the locking mechanism 1 that is already in the locking state, the free end of the second positioning member 122 included in the first locking assembly 12 is provided with a groove 1222, and the shape of the groove 1222 is various and is determined according to the detaching tool used. For example, when the used disassembling tool is a hexagon wrench, the recess 1222 is an inner hexagon screw groove, and the locking through hole 120 formed in the first positioning member 121 of the first locking assembly 12 is threadedly locked with the second positioning member 122. When the locking mechanism 1 connects the first section bar 21 and the second section bar 22, the hexagonal wrench can be used to be clamped in the hexagonal screw groove, and then the hexagonal wrench is rotated, so that the second positioning member 122 included in the first locking assembly 12 can be gradually taken out from the locking through hole 120 formed in the first positioning member 121 by using the hexagonal wrench.

In some possible implementations, as shown in fig. 1 and 2, in order to ensure that the second positioning member 122 included in the first locking assembly 12 can be locked with the corresponding locking through hole 120 formed in the first positioning member 121, the second positioning member 122 included in the first locking assembly 12 is locked with the locking through hole 120 formed in the first positioning member 121 in a threaded manner. At this time, the first positioning member 121 of the first locking assembly 12 has a through hole 120 with an internal thread. The first locking assembly 12 including the locking through hole 120 has an external thread on an outer surface of the second positioning member 122 for locking with the internal thread.

In some possible implementations, as shown in fig. 1 and fig. 2, the first positioning element 121 is provided with a sleeve through hole 1210 communicating with the locking through hole 120, so as to facilitate the first positioning element 121 included in the first locking component 12 to be sleeved on the connecting rod 111. It should be understood that, when the hole depth direction of the first limiting hole 110 formed on the connecting rod 111 is perpendicular to the axial direction of the connecting rod 111, when the locking mechanism 1 is in the locked state, the hole depth direction of the sleeve through hole 1210 formed on the first positioning element 121 included in the first locking component 12 should be parallel to the axial direction of the connecting rod 111, and the hole depth direction of the locking through hole 120 formed on the first positioning element 121 included in the first locking component 12 should be parallel to the hole depth direction of the first limiting hole 110.

In some possible implementations, as shown in fig. 1 and fig. 2, since the connecting rod 111 is provided with the first limiting hole 110, the first locking component 12 can be used to cooperate with the first limiting hole 110 to limit the position of one end of the connecting rod 111. In order to facilitate the position limitation of the other end of the connecting rod 111, a position limitation structure 114 disposed on the connecting rod 111 may be further included in the connecting assembly 11. The shape and configuration of the retention structure 114 may vary.

In some embodiments, as shown in fig. 1 and fig. 2, the position-limiting structure 114 may be a circular-disk-shaped position-limiting element, an oval-shaped position-limiting element, and the like, but is not limited thereto.

In other embodiments, as shown in fig. 1-5, the locking mechanism 1 further comprises a second locking assembly as a locking key. The structure of the second locking assembly is the same as that of the first locking assembly 12 described above. Correspondingly, the connecting rod 111 is provided with a second limiting hole, and the shape of the second limiting hole is the same as that of the first limiting hole 110.

As shown in fig. 1 to 5, when the locking mechanism 1 is in the locked state, the first positioning member included in the second locking assembly is sleeved on the connecting rod 111, and the locking through hole of the first positioning member included in the second locking assembly is communicated with the second limiting hole. The second locking component comprises a second positioning piece, and the limiting end of the second positioning piece is clamped in the second limiting hole. When in use, when the connecting rod 111 is arranged on the first section bar 21, one end of the connecting rod 111 can be fixed on the first section bar 21 by using the second locking assembly.

As shown in fig. 1 to 5, for the mutual matching relationship between the second locking element and the second position-limiting hole, reference is made to the description of the first locking element 12 and the first position-limiting hole 110, and the detailed description is omitted here.

As shown in fig. 1 to 5, in order to facilitate the second locking assembly to be accurately inserted into the second limiting hole, the connecting assembly 11 further includes a second limiting spring when the locking mechanism 1 is in the locked state. The second limiting spring comprises a fixed end and a butting end, and the fixed end of the second limiting spring is clamped on the connecting rod 111. When the locking mechanism 1 is in a locking state, the abutting end of the second limiting spring abuts against the outer surface of the first positioning piece included by the second locking assembly. As for the action principle of the second limiting spring, the action principle of the first limiting spring 112 is referred to and will not be repeated here.

As shown in fig. 1 to 5, in order to facilitate the first limiting spring 112 and the second limiting spring to be clamped on the connecting rod 111, the connecting assembly 11 further includes a limiting sleeve 113 sleeved on the connecting rod 111. The stop collar 113 is located between the first stop spring 112 and the second stop spring. At this time, one end of the position-limiting sleeve 113 adjacent to the first position-limiting spring 112 abuts against the fixed end of the first position-limiting spring 112, and one end of the position-limiting sleeve 113 adjacent to the second position-limiting spring abuts against the fixed end of the first position-limiting spring 112. It should be understood that when the position-limiting sleeve 113 is located between the first position-limiting spring 112 and the second position-limiting spring, and the position-limiting sleeve 113 is located between the first position-limiting hole 110 and the second position-limiting hole, when the locking mechanism 1 is in the locking state, the abutting end of the first position-limiting spring 112 abuts against the outer surface of the first positioning member 121 included in the first locking assembly 12, and the abutting end of the second position-limiting spring abuts against the outer surface of the first positioning member included in the second locking assembly.

In addition, as shown in fig. 1 to 5, the position limiting sleeve 113 may be fixedly disposed on the connecting rod 111 to increase the structural strength of the connecting rod 111. When the locking mechanism 1 is used for connecting two section bars, the connecting strength of the two section bars can be increased while the two section bars are connected.

The embodiment of the utility model provides a still provide a can dismantle section bar. The detachable profile is made of various materials. Fig. 5 shows an exploded view of a detachable profile comprising a first profile section 21, a second profile section 22 and at least one locking mechanism 1 as described above. The locking means 1 shown in fig. 5, although only two, do not represent that one, three or more than three locking means 1 may not be applied in the detachable profile.

As shown in fig. 5, each locking mechanism 1 secures together a first profile segment 21 and a second profile segment 22. Each locking mechanism 1 comprises a connecting rod 111 of which the connecting assembly 11 comprises one end is clamped to the first profile section 21. As shown in fig. 1, 2 and 5, each locking mechanism 1 includes a portion of the connecting rod 111 opened with the first limiting hole 110, which is located in the second section bar 22. The first positioning element 121 of the first locking assembly 12 of each locking mechanism 1 engages in the second profile section 22. At this time, the second positioning member 122 included in the first locking assembly 12 included in each of the locking mechanisms 1 clamps the other end of the connecting rod 111 included in the corresponding connecting assembly 11 to the second profile section 22.

Compared with the prior art, the embodiment of the utility model provides a can dismantle the beneficial effect of section bar is the same with above-mentioned locking mechanical system's beneficial effect, does not do here and describes repeatedly.

In some possible implementations, as shown in fig. 5, the purpose and function of the first profile section 21 and the purpose and function of the second profile section 22 may be the same or different. That is, the locking mechanism 1 shown in fig. 1 can be split together in different use, function or same use, function profile sections.

In some possible implementations, as shown in fig. 5, the material contained in the first profile section 21 and the material contained in the second profile section 22 may be the same or different. That is, the locking mechanism 1 shown in fig. 1 can be split together sections of different or identical materials.

In some possible implementations, as shown in fig. 5, the strength of the first profile section 21 and the strength of the second profile section 22 may be the same or different. That is, the locking mechanism 1 shown in fig. 1 can be split together with different or equal strength profile sections.

In some possible implementations, as shown in fig. 1, 2 and 5, in view of the fact that one end of the connecting rod 111 included in the connecting assembly 11 is clamped to the first profile section 21, and the second positioning member 122 included in the first locking assembly 12 included in each locking mechanism 1 clamps the other end of the connecting rod 111 included in the corresponding connecting assembly 11 to the second profile section 22, the first profile section 21 serves as a main bearing body to carry the connecting assembly 11, and the second profile section 22 serves as an auxiliary bearing body, so that the detachable profile formed by the first profile section 21 and the second profile section 22 can be better ensured to have good strength and stability.

Specifically, as shown in fig. 1, fig. 2 and fig. 5, since the first profile section 21 and the second profile section 22 are detachably connected by using at least one locking mechanism 1, if the connection end surface of the first profile section 21 contacts with the connection end surface of the second profile section 22, the strength of the detachable profile at the contact position between the first profile section 21 and the second profile section 22 is poor, based on this, when the connection assembly 11 included in the locking mechanism 1 includes the position-limiting sleeve 113, the first position-limiting spring 112 and the second position-limiting spring, the first position-limiting spring 112 is located in the first profile section 21, the second position-limiting spring is located in the second profile section 22, and the position-limiting sleeve 113 includes the first position-limiting section 113a and the second position-limiting section 113 b. The first position-limiting section 113a is located between the second position-limiting section 113b and the second position-limiting spring, so that the second position-limiting section 113b is located between the first position-limiting section 113a and the first position-limiting spring 112. When the stop collar 113 is fixedly arranged on the connecting rod 111, the strength of the part of the connecting rod 111 corresponding to the stop collar 113 is higher, the first stop spring 112 is positioned in the first profile section 21, and the second stop spring is positioned in the second profile section 22, so that the strength of the detachable profile at the contact position of the first profile section 21 and the second profile section 22 can be enhanced by the stop collar 113.

In some possible implementations, as shown in fig. 1, 2 and 5, the structure of the first profile section 21 and the structure of the second profile section 22 may be the same or different. That is, the locking mechanism 1 can be used to splice together different or identical profile sections.

In some possible implementations, in order to reduce the weight of the detachable profile and to reduce the material usage of the detachable profile, as shown in fig. 5 and 6, the first profile section 21 has at least one first functional groove 21a extending in the section extension direction of the first profile section 21. As shown in fig. 5 and 8, the second profile section 22 has at least one second functional groove 22a extending in the section extension direction of the second profile section 22.

The locking piece that uses when splicing to current detachable section bar generally is nut, round pin body, hasp etc.. In the actual splicing process, through holes such as screw holes and the like are often required to be formed in the section bars so as to fix locking mechanisms such as nuts, pin bodies and lock catches on the section bars, thereby realizing the splicing of the section bars. However, the through holes formed in these profile sections are often exposed, which not only affects the appearance of the display device, but also tends to wear components near the outer portions of the locking mechanism. For this, as shown in fig. 5, at least one first functional groove 21a communicates with at least one second functional groove 22a in a one-to-one correspondence. One end of the connecting rod 111 included in each locking mechanism 1 shown in fig. 1 is clamped in the first functional groove 21a, and the portion of the connecting rod 111 included in each locking mechanism 1, where the first limiting hole 110 is formed, is located in the second functional groove 22 a. As shown in fig. 2 and fig. 5, the first positioning element 121 included in the first locking component 12 included in each locking mechanism 1 is clamped in the second functional groove 22a, so that the second positioning element 122 included in the first locking component 12 included in each locking mechanism 1 clamps the connecting rod 111 in the second functional groove 22a, and the connecting rod 111 clamped in the first functional groove 21a and the first positioning element 121 clamped in the corresponding second functional groove 22a are located in the same locking mechanism 1. Therefore, at least one locking mechanism 1 can be accommodated by utilizing the first functional groove 21a formed in the first profile section 21 and the second functional groove 22a formed in the second profile section 22, so that the first profile section 21 and the second profile section 22 can be detachably connected, therefore, the first functional groove 21a formed in the first profile section 21 and the second functional groove 22a formed in the second profile section 22 can reduce the gravity of the detachable profile and reduce the usage amount of materials, and can also provide an accommodating space for the locking mechanism 1, and installation positions do not need to be newly formed in the first profile section 21 and the second profile section 22, so that the original structures of the first profile section 21 and the second profile section 22 can be maximally stored.

In some embodiments, as shown in fig. 2 and 5, when the first positioning element 121 of the first locking assembly 12 of each locking mechanism 1 shown in fig. 1 is clamped in the second functional groove 22a, the second positioning element 122 of the first locking assembly 12 of each locking mechanism 1 can extend into the locking through hole 120 of the corresponding first positioning element 121 by using the notch of the second functional groove 22a, so that a through hole does not need to be formed in the second profile segment 22. For example: the depth direction of the locking through hole 120 of the first positioning element 121 included in the first locking component 12 is the same as the depth direction of the second functional groove 22a, so that the limiting end of the second positioning element 122 included in the first locking component 12 can extend into the locking through hole 120 formed in the first positioning element 121 from the notch of the second functional groove 22a, and unnecessary through holes are prevented from being formed in the second profile section 22. When the free end of the second positioning element 122 included in the first locking component 12 is provided with the groove 1222, if the groove 1222 is an inner hexagonal screw groove, the inner hexagonal wrench can be inserted into the inner hexagonal screw groove through the notch of the second functional groove 22a, so that the second positioning element 122 included in the first locking component 12 can be taken out from the locking through hole 120 by using the inner hexagonal wrench, and thus, the end of the connecting rod 111 included in the connecting component 11 included in the positioning mechanism, which extends out of the first section bar 21, can be taken out from the second functional groove 22 a.

It should be understood that, as shown in fig. 2 and 5, when the connecting rod 111 included in each locking mechanism 1 shown in fig. 1 is provided with the second limiting hole, and the first positioning element included in the second locking assembly included in each locking mechanism 1 is clamped in the second functional groove 22a, the second positioning element included in the second locking assembly included in each locking mechanism 1 can extend into the locking through hole provided in the corresponding first positioning element by using the notch of the second functional groove 22a, so that a through hole does not need to be provided in the first profile segment 21. For example: when the locking mechanism 1 comprises the second locking assembly with the same structure as the first locking assembly 12, the hole depth direction of the locking through hole of the first positioning piece of the second locking assembly is the same as the groove depth direction of the first functional groove 21a, so that the limit end of the second positioning piece of the second locking assembly can extend into the locking through hole of the first positioning piece through the notch of the first functional groove 21a, thereby avoiding the first profile section 21 from being provided with unnecessary through holes. Similarly, the process of taking out the second positioning element contained in the second locking assembly from the locking through hole formed in the first positioning element contained in the second locking assembly can be related to the process of taking out the second positioning element 122 contained in the first locking assembly 12 from the locking through hole 120 formed in the first positioning element 121 contained in the first locking assembly 12.

In some embodiments, as shown in fig. 5, 10 and 11, when at least one first functional groove 21a communicates with at least one second functional groove 22a in a one-to-one correspondence, the cross-sectional structures of the first profile segments 21 are the same as the cross-sectional structure of the second profile segments 22, and the widths of the first functional grooves 21a are the same as the widths of the corresponding second functional grooves 22 a. It should be understood that the first profile section 21 and the second profile section 22 may be aluminum extrusions, but may also be other types of profiles.

As shown in fig. 1, 2 and 5, the width direction of the first functional groove 21a is perpendicular to the section extension direction of the first profile section 21. The width direction of the second functional groove 22a is perpendicular to the section extending direction of the second profile section 22. When the first profile section 21 and the second profile section 22 are detachably connected together, the connecting rod 111 clamped by the first functional groove 21a and the first positioning element 121 clamped by the second functional groove 22a are in the same locking mechanism 1, so that the first profile section 21 and the second profile section 22 can be accurately aligned, and alignment deviation between the first profile section 21 and the second profile section 22 cannot occur.

In some possible implementations, as shown in fig. 1, 2 and 5, in order to ensure that one end of the connecting rod 111 included in the connecting assembly 11 included in each locking mechanism 1 can be clamped in the first functional groove 21a, one end of the connecting rod 111 included in the connecting assembly 11 included in each locking mechanism 1 may be embedded in the first functional groove 21a, or may be fixed in the first functional groove 21a by using a special structure. Similarly, the first positioning element 121 included in the first locking component 12 of each locking mechanism 1 may be embedded in the second functional groove 22a, or may be fixed in the second functional groove 22a by adopting a special structure.

As shown in fig. 5 and 7, the inner side wall of at least one first functional groove 21a is provided with a first limiting groove 21b that limits in the section extending direction of the first profile section 21. As shown in fig. 5 and 9, an inner sidewall of at least one second functional groove 22a is provided with a second limiting groove 22b limiting in a section extending direction of the second profile section 22. As shown in fig. 5, 7 and 9, at least one first functional groove 21a of the first limiting groove 21b formed in the inner side wall and at least one second functional groove 22a of the second limiting groove 22b formed in the inner side wall are in one-to-one correspondence with at least one locking mechanism 1. At this time, as shown in fig. 1, fig. 2 and fig. 5, the length of the first positioning element 121 included in the first locking component 12 of the locking mechanism 1 along the width direction of the second functional groove 22a (the width direction of the second functional groove 22a is perpendicular to the section extending direction of the second profile section 22) should be greater than the width of the corresponding second functional groove 22a, so as to ensure that the first positioning element 121 included in the first locking component 12 of the locking mechanism 1 can be clamped in the corresponding second functional groove 22a, and thus prevent the first positioning element 121 included in the first locking component 12 of the locking mechanism 1 from being pulled out along the section extending direction of the first profile section 21 in the corresponding second functional groove 22 a. Further, as shown in fig. 1, fig. 2, fig. 5 and fig. 9, the first positioning element 121 included in the first locking component 12 of the locking mechanism 1 is clamped in the second limiting groove 22b formed in the inner side wall corresponding to the second functional groove 22a, so as to prevent the first positioning element 121 included in the first locking component 12 of the locking mechanism 1 from moving in the corresponding second functional groove 22a along the section extending direction of the second profile segment 22.

As shown in fig. 1, 2 and 5, when the connecting assembly 11 included in the locking mechanism 1 includes the limiting structure 114 disposed on the connecting rod 111, a length of the limiting structure 114 included in the connecting assembly 11 included in the locking mechanism 1 along a width direction of the first functional groove 21a (the width direction of the first functional groove 21a is perpendicular to the section extending direction of the first profile section 21) is greater than a width of the first functional groove 21a, so as to ensure that the limiting structure 114 included in the connecting assembly 11 included in the locking mechanism 1 can be clamped in the corresponding first functional groove 21a, thereby preventing the limiting structure 114 included in the connecting assembly 11 included in the locking mechanism 1 from being removed from the corresponding first functional groove 21a along the section extending direction of the first profile section 21. Further, as shown in fig. 1, fig. 2, fig. 5 and fig. 7, the limiting structure 114 included in the connecting assembly 11 included in the locking mechanism 1 is clamped in the first limiting groove 21b formed in the inner side wall corresponding to the first functional groove 21a, so as to prevent the limiting sleeve 113 included in the connecting assembly 11 included in the locking mechanism 1 from moving along the section extending direction of the first profile section 21 in the corresponding first functional groove 21 a. It should be understood that the position of the first limiting groove 21b in the first functional groove 21a shown in fig. 7 and the position of the second limiting groove 22b in the second functional groove 22a shown in fig. 9 can be adjusted to control the length of the connecting rod 111 extending out of the first profile section 21 and the position of the first positioning element 121 in the second functional groove 22a to ensure that the end of the connecting rod 111 extending out of the first profile section 21 shown in fig. 5 can completely extend into the second functional groove 22a formed in the second profile section 22 and be clamped in the second functional groove 22a formed in the second profile section 22 by the second positioning element 122, thereby ensuring that the end of the first profile section 21 and the end of the second profile section 22 are in surface-to-surface contact when the locking mechanism 1 is in the locking state.

As shown in fig. 1, 2 and 5, in order to prevent the connecting rod 111 of the connecting assembly 11 included in the locking mechanism 1 from coming out of the notch of the corresponding first functional groove 21a, the first positioning member 121 of the first locking assembly 12 comes out of the notch of the second functional groove 22a, and as shown in fig. 10 and 11, the first functional groove 21a and the second functional groove 22a corresponding to the locking mechanism 1 illustrated in fig. 1 each include a large opening portion GND and a small opening portion GNX.

Specifically, as shown in fig. 1, 2, 5, 10, and 11, in order to prevent the stopper structure 114 included in the coupling assembly 11 included in the locking mechanism 1 from coming out of the notch of the corresponding first functional groove 21a (the surface where the notch of the first functional groove 21a is located is perpendicular to the groove depth direction of the first functional groove 21 a), the first functional groove 21a corresponding to the locking mechanism 1 includes a first large mouth portion and a first small mouth portion that locks the stopper structure included in the coupling assembly 11 included in the corresponding locking mechanism 1 to the first large mouth portion. The first small mouth portion and the first large mouth portion are distributed along the groove depth increasing direction of the first functional groove 21 a. It should be understood that the length of the first small opening portion included in the corresponding first functional groove 21a of the locking mechanism 1 along the width direction of the first functional groove 21a should be smaller than the length of the limiting structure 114 included in the connecting assembly 11 included in the corresponding locking mechanism 1 along the width direction of the first functional groove 21a, so as to ensure that the limiting structure 114 included in the connecting assembly 11 included in the locking mechanism 1 can be clamped in the first large opening portion by the first small opening portion included in the corresponding first functional groove 21 a.

Specifically, as shown in fig. 1, 2, 5, 10 and 11, in order to prevent the first positioning member 121 included in the first locking component 12 included in the locking mechanism 1 from coming out of the notch of the second functional groove 22a (the groove depth direction of the second functional groove 22a is perpendicular to the surface where the notch of the second functional groove 22a is located), the second functional groove 22a corresponding to the locking mechanism 1 includes a second large mouth portion and a second small mouth portion for locking the first positioning member 121 included in the first locking component 12 included in the corresponding locking mechanism 1 to the second large mouth portion, and the second small mouth portion and the second large mouth portion are distributed in the direction in which the groove depth of the second functional groove 22a increases. It should be understood that the length of the second small opening portion included in the corresponding second functional groove 22a of the locking mechanism 1 along the width direction of the second functional groove 22a should be smaller than the length of the first positioning element 121 included in the corresponding first locking component 12 included in the locking mechanism 1 along the width direction of the second functional groove 22a, so as to ensure that the first positioning element 121 included in the corresponding first locking component 12 included in the locking mechanism 1 can be clamped in the second large opening portion by the second small opening portion included in the corresponding second functional groove 22 a.

As shown in fig. 1, 2 and 5, when the locking mechanism 1 includes a second locking assembly having the same structure as the first locking assembly 12, the length of the first positioning element included in the second locking assembly included in the locking mechanism 1 along the width direction of the first functional groove 21a (the width direction of the first functional groove 21a is perpendicular to the section extending direction of the first profile section 21) is greater than the width of the first functional groove 21a, so as to ensure that the first positioning element included in the second locking assembly included in the locking mechanism 1 can be clamped in the corresponding first functional groove 21a, thereby preventing the first positioning element included in the second locking assembly included in the locking mechanism 1 from being pulled out of the corresponding first functional groove 21a along the section extending direction of the first profile section 21. Further, as shown in fig. 1, fig. 2 and fig. 5, the first positioning element included in the second locking assembly included in the locking mechanism 1 is clamped in the first limiting groove 21b formed in the inner side wall corresponding to the first functional groove 21a, so as to prevent the first positioning element included in the second locking assembly included in the locking mechanism 1 from moving along the section extending direction of the first profile section 21 in the corresponding first functional groove 21 a.

As shown in fig. 1, 2, 5, 10 and 11, in order to prevent the first positioning member 121 included in the first locking component 12 included in the locking mechanism 1 from coming out of the notch of the corresponding second functional groove 22a and prevent the first positioning member included in the second locking component from coming out of the notch of the corresponding first functional groove 21a, the first functional groove 21a and the second functional groove 22a corresponding to the locking mechanism 1 each include a large opening portion GND and a small opening portion GNX.

Specifically, as shown in fig. 1, 2, 5, 10 and 11, in order to prevent the first positioning member included in the second locking assembly included in the locking mechanism 1 from coming out of the notch of the corresponding first functional groove 21a (the surface where the notch of the first functional groove 21a is located is perpendicular to the groove depth direction of the first functional groove 21 a), the first functional groove 21a corresponding to the locking mechanism 1 includes a first large mouth portion and a first small mouth portion for locking the first positioning member included in the second locking assembly included in the corresponding locking mechanism 1 to the first large mouth portion, and the first small mouth portion and the first large mouth portion are distributed along the groove depth increasing direction of the first functional groove 21 a. It should be understood that the length of the first small opening portion included in the first functional groove 21a corresponding to the locking mechanism 1 along the width direction of the first functional groove 21a should be smaller than the length of the first positioning member included in the second locking attachment component included in the corresponding locking mechanism 1 along the width direction of the first functional groove 21a, so as to ensure that the first positioning member included in the second locking attachment component included in the locking mechanism 1 can be clamped in the first large opening portion by the first small opening portion included in the corresponding first functional groove 21 a.

Specifically, as shown in fig. 1, 2, 5, 10 and 11, in order to avoid the first positioning member 121 included in the first locking component 12 included in the locking mechanism 1 from coming out of the notch of the corresponding second functional groove 22a (the groove depth direction of the second functional groove 22a is perpendicular to the surface where the notch of the second functional groove 22a is located), the second functional groove 22a corresponding to the locking mechanism 1 includes a second large mouth portion and a second small mouth portion for locking the first positioning member 121 included in the first locking component 12 included in the corresponding locking mechanism 1 to the second large mouth portion, and the second small mouth portion and the second large mouth portion are distributed along the direction in which the groove depth of the second functional groove 22a increases. It should be understood that the length of the second small opening portion included in the corresponding second functional groove 22a of the locking mechanism 1 along the width direction of the second functional groove 22a should be smaller than the length of the first positioning element 121 included in the corresponding first locking component 12 included in the locking mechanism 1 along the width direction of the second functional groove 22a, so as to ensure that the first positioning element 121 included in the corresponding first locking component 12 included in the locking mechanism 1 can be clamped in the second large opening portion by the second small opening portion included in the corresponding second functional groove 22 a.

It will be appreciated that the direction of extension of the first profile section 21 and the direction of extension of the second profile section 22 may be the same or different, as shown in fig. 5. That is, the locking mechanism 1 shown in fig. 1 can be assembled together with profile sections of different or identical extension directions. For example: as shown in fig. 5, both the segment extending direction of the first profile segment 21 and the segment extending direction of the second profile segment 22 are straight segment extending directions. Another example is: the section extending direction of the first section bar 21 is a straight section extending direction, and the section extending directions of the second section bar 22 are arc section extending directions.

In some possible implementations, as shown in fig. 5, in order to ensure seamless connection of the first profile section 21 and the second profile section 22, one end of the first profile section 21 adjacent to the second profile section 22 is in surface-to-surface contact with one end of the second profile section 22 adjacent to the first profile section 21.

As shown in fig. 12 and 13, in view of the fact that the size specification and the product model of the image capturing device 330 may vary with the space size of the consultation site where the medical display device is applied, the detachable point range a of the first vertical beam 101B and the detachable point range B of the second vertical beam 102B shown in the figure may divide the corresponding vertical beam into two sections, that is, a lower vertical beam section bd for fixing the first cross beam 101a, the second cross beam 102a, the third cross beam 103a, the fourth cross beam 104a and the fifth cross beam 105a and an upper vertical beam section bu for fixing the fifth cross beam 105a, and detachably connect them by using the locking mechanism 1. At this time, the lower vertical beam section bd and the upper vertical beam section bu correspond to the first profile section 21 and the second profile section 22, and the detailed structure can also refer to the related description of the first profile section 21 and the second profile section 22 shown in fig. 5.

As shown in fig. 12, when the vertical beam is divided into two sections at the detachable point of the first vertical beam 101b and the detachable point of the second vertical beam 102b shown in fig. 13, if the size specification of the image capturing device 330 becomes large, resulting in that the space between the first cross beam 101a and the second cross beam 102a cannot accommodate the image capturing device 330, the detachable point of the first vertical beam 101b and the detachable point of the second vertical beam 102b can be detached, and a longer upper vertical beam section can be replaced, so that the space between the first cross beam 101a and the second cross beam 102a cannot accommodate the image capturing device 330.

In addition, as shown in fig. 12 and 13, since the first vertical beam 101b and the fifth horizontal beam 105a are different from the first arc-shaped connector 101d in structure, the first vertical beam 101b and the first arc-shaped connector 101d cannot be manufactured by the same machining process, and the fifth horizontal beam 105a and the first arc-shaped connector 101d cannot be manufactured by the same machining process, the first vertical beam 101b and the first arc-shaped connector 101d need to be detachably connected by the locking mechanism 1. The fifth beam 105a and the first curved connecting member 101d need to be detachably connected together by the locking mechanism 1. Similarly, the second vertical beam 102b and the second arc-shaped connecting member 102d need to be detachably connected together by using the locking mechanism 1. The fifth beam 105a and the second curved connecting member 102d need to be detachably connected together by the locking mechanism 1. Fig. 12 illustrates a detachable point range C of the first vertical beam 101b, the first arc-shaped connector 101D, and the fifth beam 105a, and a detachable point range D of the second vertical beam 102b, the second arc-shaped connector 102D, and the fifth beam 105 a. It should be understood that the structure of the first vertical beam 101b, the second vertical beam 102b, the first arc-shaped connecting member 101d and the second arc-shaped connecting member 102d can also refer to the structure of the first profile section 21 and the second profile section 22 described above, and will not be described in detail here.
