When assembling, the pin shaft 23 is inserted into the through hole 211 of the support 2, and the pin shaft 23 may be a screw pin, inserted through the first mounting hole 14c, passed through the through hole 211 of the support 2, and locked to the first screw hole, so that the support 2 is supported to the first mounting seat 11 by the pin shaft 23 and rotates around the pin shaft 23.
The mounting portion 1 is provided with a wrench portion 3, preferably, the wrench portion 3 is disposed at one side of the mounting portion 1, the wrench portion 3 is fixed to the supporting member 2, a wrench portion 31 of the wrench portion 3 is located at one side of the supporting member 2 in a radial direction, a mounting end portion 32 of the wrench portion 3 is fixed to the supporting member 2 and is accommodated in the accommodating space 14 of the mounting portion 1, and when the wrench portion 3 swings, the supporting member 2 can rotate on the first mounting seat 11 around the pin 23 with a shaft center 21a of the first rotating portion 21, i.e., a shaft center of the through hole 211, as a center. The wrench portion 3 may be fixed to the first rotation portion 21 of the support member 2 by any known means, and in this embodiment, it is preferable that the wrench portion 3 is fixed to the support member 2 coaxially with the first rotation portion 21, and when the wrench portion 3 swings, the support member 2 rotates around the axial center 21a of the first rotation portion 21. The first rotating portion 21 includes square pins 21a and 21b protruding from both ends of the support 2 in the axial direction, and the fitting grooves 321 matching with the square pins 21a and 21b are provided in the fitting end portion 32 of the wrench portion 3, and when the wrench portion is fitted, the fitting grooves 321 of the wrench portion 3 are engaged with the square pins 21a and 21b, and then the wrench portion 3 is fixed to the square pins 21a and 21b by the fixing block 33 and the locking screw 32. Thus, when the wrench portion 3 is swung, the support 2 can be rotated about the pin 23, and when the support 2 is rotated, the second rotation portion 22 swings about the pin 23.
The supporting piece 2 is further provided with a hook part 4, and the hook part 4 is located on the other radial side of the supporting piece 2 and is opposite to the wrench part 3. The hook portion 4 is substantially in a long shape, a hook 44 is provided on an upper portion 4a of the hook portion 4, the hook 44 is used for realizing a hanging state of the hook portion 4, and the hook 44 protrudes in a direction substantially perpendicular to a longitudinal direction of the hook portion 4. Preferably, the lower portion of the hook 44 is provided with a holding member 42, the holding member 42 protrudes toward the middle portion of the hook 4 along the length direction of the hook 4, the upper portion of the hook 44 is provided with a first guiding portion 43, and the first guiding portion 43 may be an arc-shaped or a slope-shaped guiding surface directly arranged on the upper surface of the hook 44. A rotation hole 41 is provided in the middle 4b of the hook 4 in the longitudinal direction, and the hook 4 is fitted to the second rotation portion 22 through the rotation hole 41. The rotation hole 41 is in clearance fit with the second rotation portion 22 so that the hook portion 4 can rotate about the axial center of the second rotation portion 22. It should be noted that the middle portion 4b of the hook 4 is not particularly limited to the middle of the hook 4, but refers to any position between both ends of the hook 4, for example, the hook 4 may be provided with a lug 45 at a position approximately midway down in the longitudinal direction thereof, and the rotation hole 41 is opened in the lug 45.
Thereby, the hook 4 can rotate about the axial center 22a of the second rotating portion 22. Moreover, since the position of the second rotating portion 22 changes and the hook portion 4 is supported by the second rotating portion 22, the hook portion 4 also changes with the change of the position of the second rotating portion 22, for example, when the axial center 22a of the second rotating portion 22 moves toward the upper side of the axial center 21a of the first rotating portion 21, the hook portion 4 also moves toward the upper side of the buckle structure 100 as a whole; when the shaft center 22a of the second rotating portion 22 moves to the lower side of the shaft center 21a of the first rotating portion 21, the entire hook portion 4 also moves to the lower side of the buckle structure 100. By providing the support member 2 having the first rotation portion 21 and the second rotation portion 22, respectively, when the wrench portion 3 fixed coaxially with respect to the first rotation portion 21 is swung, the hook portion 4 coaxial with the second rotation portion 22 can be moved along the rotation locus of the second rotation portion 22, and when the hook portion 4 moves up and down, for example, the unhooking operation or the hooking operation of the latch structure 100 can be easily performed.
Preferably, the mounting portion 1 is provided with a first restriction portion 12, and the hook portion 4 can abut against the first restriction portion 12 when rotating around the second rotation portion 22. The first restriction portion 12 may be directly provided to a side surface of the first mounting seat 11 to restrict a swing angle of the hook portion 4. For example, when the hook 4 swings around the rotation hole 41, the upper portion 4a of the hook 4 can abut against the first limiting portion 12. When the hook portion 4 abuts the first restriction portion 12, the hook portion 4 is substantially parallel to the axial direction of the mounting portion 1. Further preferably, the mounting portion 1 may further include a second limiting portion 15, and the second limiting portion 15 is disposed at a lower portion of the accommodating space 14 and is adjacent to the handle 13 of the mounting portion 1. When the hook 4 swings about the rotation hole 41, the lower portion 4c of the hook 4 can abut against the second regulating portion 15. When the hook portion 4 abuts the second restriction portion 15, the hook portion 4 is angularly offset with respect to the axial direction of the mounting portion 1, for example, by an angle between 0 ° and 10 °.
In order to control the hook portion 4, prevent the hook portion 4 from deflecting randomly, and simultaneously damp the swing of the wrench portion 3, the locking structure 100 may further include an elastic member 5, and the elastic member 5 may be disposed between the mounting portion 1 and the wrench portion 3, or between the mounting portion 1 and the hook portion 4.

Preferably, the elastic member 5 is a spring member, the mounting portion 1 is provided with a limit plate 16 in the accommodating space 14, the limit plate 16 is located on one side of the second limiting portion 15, one end of the spring abuts against the limit plate 16, the other end abuts against the lower portion 4c of the hook portion 4, and the spring makes the upper portion 4a of the hook portion 4 abut against the first limiting portion 12 in a state where the hook portion 4 is not subjected to an external force. More preferably, the elastic member 5 is a torsion spring, the torsion spring is sleeved on the second rotating portion 22, the torsion spring has two swing arms 5a and 5b, the swing arms 5a and 5b are located below the second rotating portion 22, one swing arm 5b abuts against the mounting portion 1, for example, abuts against the limit plate 16 of the accommodating space 14, the other swing arm 5a abuts against the lower portion 4c of the hook portion 4, and the upper portion of the hook portion 4 abuts against the first limiting portion 12 when the hook portion 4 is not subjected to an external force.
The following description will further describe the latch structure 100 by taking the spliced screen 200 using the latch structure 100 as an example.
Fig. 5(a) is a front view of an embodiment of the tiled display 200, fig. 5(B) is a cross-sectional view taken along line a-a of fig. 5(a), fig. 6 is a partial enlarged view taken along line B of fig. 5(B), and referring to fig. 5(a) and fig. 5(B), the tiled display 200 is formed by at least two display panels, and the latch structure 100 can be preferably used for splicing up and down display panels, and of course, can also be used for splicing horizontal display panels. Here, taking the top-bottom splicing as an example, preferably, the spliced screen 200 includes at least one first display screen 61 and one second display screen 62, the upper end surface 61a of the first display screen 61 and the lower end surface 62a of the second display screen 62 are spliced by the above-mentioned locking structure 100 in the top-bottom direction, for example, the locking structure 100 is mounted on the first display screen 61 through the mounting portion 1, as described above, the second mounting hole 121 is provided on the end surface of the first mounting seat 11 of the mounting portion 1, the locking structure 100 is locked on the first display screen 61 through the second mounting hole 121, and the upper portion 4a of the hook portion 4 of the locking structure 100 protrudes from the upper end surface 61a of the first display screen 61.
Referring to fig. 6, the guide pin 63 is disposed on the upper end surface 61a of the first display screen 61, the guide pin 63 may also be directly disposed on the locking structure 100 through the locking plate 631 (refer to fig. 3 for assistance), and the guide hole 64 is disposed on the lower end surface 62a of the second display screen 62, so that when the display screen is spliced, the first display screen 61 and the second display screen 62 can be spliced in advance conveniently through the cooperation of the guide pin 63 and the guide hole 64. The lower end surface 62a of the second display screen 62 is provided with an avoiding space 65, and when the second display screen is spliced, the hook portion 4 of the locking structure 100 can extend into the avoiding space 65. The fixing plate 66 may be connected to the lower end surface 62a of the second display 62, the fixing plate 66 may be provided with a hanging portion 661, the hanging portion 661 may be provided in the space 65, and preferably, the hanging portion 661 may be provided in a cantilever shape in the space 65 in order to facilitate the hook portion 4 to be hung on the hanging portion 661. The second guide portion 662 is provided at a lower portion of the hanging portion 661, and the second guide portion 662 may be an arc-shaped or an inclined guide surface directly provided at a lower surface of the hanging portion 661. When the guide pin 63 of the first display 61 is inserted into the guide hole 64 of the second display 62, the first guide portion 43 above the hook 44 of the hook 4 abuts against the second guide portion 662 below the hanging portion 661.
Fig. 7 is a schematic view of the latch structure 100 when the first display 61 and the second display 62 are connected, and referring to fig. 7, when the first display 61 and the second display 62 are connected, the hook portion 4 slides along the second guide portion 662 through the first guide portion 43, and at this time, due to the acting force of the second guide portion 662, the hook portion 4 swings clockwise around the second rotation portion 22 as an axis, the lower portion 4c of the hook portion 4 compresses the elastic member 5 (since the elastic member 5 is compressed at this time, the elastic member is hidden in the accommodating space 4, the position of the elastic member 5 can refer to fig. 6), the upper portion 4a of the hook portion 4 is separated from the first limiting portion 12, and the lower portion 4c of the hook portion 4 abuts against the second limiting portion 15.
Fig. 8(a) is a schematic view of the latch structure 100 when the first display panel 61 and the second display panel 62 are pre-hooked, fig. 8(b) is a partial enlarged view of fig. 8(a) C, and referring to fig. 8(a) and 8(b), when the first display panel 61 and the second display panel 62 are further spliced, the hook 44 of the hook 4 crosses the hanging portion 661 and reaches above the hanging portion 661, at this time, the first guide portion 43 and the second guide portion 662 are separated, the hook 4 swings counterclockwise around the second rotation portion 22 under the action of the elastic member 5 and is primarily hooked to the hanging portion 661, the hanging portion 661 is provided with a groove 663, and after the hook 4 is primarily hooked to the hanging portion, the catch member 42 is caught in the groove 663. At this time, the axial center 22a of the second rotating portion 22 is located on the left side of the axial center 21a of the first rotating portion 21.
Thus, by providing the first guide portion 43 and the second guide portion 662, the hook portion 4 can be easily hooked to the hanging portion 661 without performing an additional operation on the latch structure 100. Further, since the hook 4 can be swung counterclockwise by the elastic member 5, the hook 4 can be reliably hooked to the hanging portion 661. Further, since the lower portion of the hook 44 is provided with the catching member 42 and the hanging portion 661 is provided with the groove 663, after the hook 4 is preliminarily caught to the hanging portion 661, since the catching member 42 is caught in the groove 663, the hook 4 can be prevented from being unhooked from the hanging portion 661.
Fig. 9(a) is a schematic view of the latch structure 100 when the first display 61 and the second display 62 are completely connected, fig. 9(b) is a partial enlarged view of fig. 9(a) D, fig. 9(a) and 9(b) are shown with additional reference to fig. 8(b), after the hook 44 of the hook portion 4 is initially hooked on the suspension portion 661, the wrench portion 3 is swung counterclockwise so that the axial center 22a of the second rotation portion 22 is rotated from the left lower side of the axial center 21a of the first rotation portion 21 to the right lower side of the axial center 21a of the first rotation portion 21, and in conjunction therewith, the hook 44 of the hook portion 4 is also moved from the middle left position of the suspension portion 661 (when the axial center 22a of the second rotation portion 22 is on the left lower side of the axial center 21a of the first rotation portion 21), to the middle right position of the suspension portion 661 (when the axial center 22a of the second rotation portion 22 is on the right lower side of the axial center 21a of the first rotation portion, at this time, the side wall 42a of the retaining member 42 is completely attached to the side wall 663a of the groove 663, and the hooking of the locking structure 100 is completed.
In the above description, when the swing wrench portion 3 rotates the support 2 about the axial center 21a of the first rotating portion 21, the axial center 22a of the second rotating portion 22 is switched between one side (e.g., one side of the wrench portion 3) of the axial center 21a of the first rotating portion 21 in the horizontal direction and the other side (e.g., one side of the hook portion 4) of the axial center 21a of the first rotating portion 21. That is, the relative relationship between the wrench portion 3 and the hook portion 4 is set as: in the initial (unhooked) state, the wrench portion 31 of the wrench portion 3 is positioned on the upper left side of the first rotating portion 21, and the shaft center 22a of the second rotating portion 22 is positioned on the lower left side of the shaft center 21a of the first rotating portion 21. When the wrench portion 3 is swung counterclockwise, the axis 22a of the second rotation portion 22 rotates around the axis 21a of the first rotation portion 21, and at the same time, the hook portion 4 moves downward of the latch structure 100, and when the axis 22a of the second rotation portion 22 crosses the right lower side of the axis 21a of the first rotation portion 21 in the vertical direction right below the axis 21a of the first rotation portion 21, the hook portion 4 is in a hooked state. At this time, the axial center 22a of the second rotating portion 22 crosses directly below the axial center 21a of the first rotating portion 21 in the vertical direction, and it is difficult to automatically return to the original position without applying an external force. On the other hand, due to the gravity of the first display 61, the hanging portion 661 applies a counterclockwise force to the hook portion 4, and at the same time, the elastic member 5 also applies a counterclockwise force to the hook portion 4. Further, since the counterclockwise direction of the second rotating portion 22 is the hooking direction, that is, the hooking direction tends to be further hooked by the hooking portion 661, the hook portion 4 can be self-locked.
The following describes a process of installing the tiled screen 200 by the locker structure 100.
The first step is as follows: pre-splicing, wherein an operator grasps the handle 13 of the mounting part 1 of the locking structure 100 of the first display screen 61 with two hands to lift the first display screen 61 upwards, and pre-splicing the first display screen 61 and the second display screen 62 is performed through matching of the guide pin 63 and the guide hole 64; the second step is that: the first guide portion 43 of the hook portion 4 abuts against the second guide portion 662 of the hanging portion 661, and the second guide portion 662 presses the hook portion 4, at which time the hook portion 4 swings clockwise; the third step: the first guide portion 43 and the second guide portion 662 are separated, at this time, the hook portion 4 swings counterclockwise (when the elastic member 5 is provided, the elastic member 5 automatically swings the hook portion 4 counterclockwise, and when the elastic member 5 is not provided, the hook portion 4 can swing counterclockwise by the action of the finger of the operator), after the hook 44 of the hook portion 4 reaches above the hanging portion 661, the operator releases both hands, and at this time, the hook portion 4 is hung on the hanging portion 661; the fourth step: the operator swings the wrench part 3 counterclockwise, the second rotating part 22 rotates around the first rotating part 21, the shaft center 22a of the second rotating part 22 rotates to a position right below the shaft center 21a of the first rotating part 21 from the left lower side of the shaft center 21a of the first rotating part 21, and in linkage with the shaft center, the hook 44 moves downward to a position right from the middle of the hanging part 661 from a position left from the middle of the hanging part 661, and the side wall 42a of the clamping piece 42 is attached to the side wall 663a of the groove 663, so that the splicing of the first display screen 61 and the second display screen 62 and the self-locking of the locking structure 100 are completed.
The step of detaching the tiled screen 200 by the latch structure 100 is explained below.
The first step is as follows: the wrench part 3 is swung clockwise to separate the hook 44 from the hanging part 661; the second step is that: the operator holds the handle 13 of the mounting part 1 of the locking structure 100 with his/her hands, swings the lower part 4c of the hook 4 clockwise, compresses the elastic member 5, and causes the lower part 4c of the hook 4 to abut against the second limiting part 15, at which time, the hook 44 moves away from above the hanging part 661; the third step: the operator holds the handles 13 of the mounting portion 1 with both hands, and lowers the first display screen 61 to complete the mounting and dismounting of the first display screen 61 and the second display screen 62.
In this process, only one operator is needed to complete the splicing work and the disassembling work of the first spliced screen 61 and the second spliced screen 62, and the operator can conveniently disassemble and assemble the spliced screen 200.
The various features described in the foregoing detailed description may be combined in any manner and, for the sake of unnecessary repetition, various combinations are not intended to be encompassed by the invention.
The above embodiments are merely illustrative of the technical solutions of the present invention and are not restrictive, and any modifications or equivalent substitutions which do not depart from the scope of the present invention should be included in the technical solutions of the present invention.
