Example 1

As shown in fig. 1 to 33 and 44 to 56, embodiment 1 of the present invention discloses a connecting assembly, which includes a first connecting member 100 and a second connecting member 200, for example, by first installing the first connecting member 100 on a first member 500, installing the second connecting member 200 on a second member 600, and then connecting the first connecting member 100 and the second connecting member 200 to each other, a stable connection between the first member 500 and the second member 600 can be achieved, and the first member 500 or the second member 600 has a strong bearing capacity; meanwhile, the surfaces of the first member 500 or the second member 600 do not need to be damaged when the first connecting piece 100 and the second connecting piece 200 are installed or connected, and the requirement of a user on the aesthetic pursuit of a finished furniture product is met. For example, the second connecting member 200 is fixed to the surface of the second member 600 in an unreleasable manner, or the second connecting member 200 and the second member 600 are integrally formed, the first connecting member 100 is mounted on the first member 500, and the first connecting member 100 and the second connecting member 200 are connected with each other, so that the first member 500 and the second member 600 can be stably connected, and the first member 500 or the second member 600 has strong bearing capacity.

The specific structure of the first connecting member 100 of the present embodiment 1 will be further described below.

As shown in fig. 1 to 28, the embodiment 1 discloses a first connector 100, which includes a first connector body having a first surface 101 and a second surface 102 connected to each other, the first surface 101 of the first connector body is provided with a first channel 103 extending transversely and a second channel 104 extending longitudinally, a first end 1045 of the second channel 104 extending longitudinally is communicated with the first channel 103, and a second end 1046 of the second channel 104 extending longitudinally penetrates through the second surface 102 of the first connector body to form a first access hole 1041; at least one end of the first passage 103 in the transverse direction is a first closed end 1031; the first channel 103 and the second channel 104 define a mounting channel for connection with the second connector 200.

After the second connecting member 200 enters the second end 1046 of the second passage 104 from the first access hole 1041, slides along the second passage 104 to the first end 1045 of the second passage 104, slides into the first passage 103 after passing through the communication position between the first passage 103 and the second passage 104, and is connected to the first passage 103 through the second connecting member 200, so that the first connecting member 100 and the second connecting member 200 are connected to each other, thereby achieving the purpose of connecting the first member 500 and the second member 600 to each other. For convenience of description, this embodiment 1 sets a portion of the second connector 200 for connection in the mounting passage as the connection portion 201.

In embodiment 1 of the present invention, the connection between the first connection member 100 and the second connection member 200 can be achieved after the connection portion 201 slides to any position in the first passage 103, for example, the connection portion 201 can slide to the middle of the first passage 103, and for example, the connection portion 201 can slide to the first closed end 1031 or close to the first closed end 1031.

Because the first closed end 1031 is closed, the structural strength of the first closed end 1031 is greater than that of the middle part of the first passage 103 or other positions of the first passage 103, when the connecting portion 201 slides to the first closed end 1031 or approaches the first closed end 1031, the acting force of the first member 500 bearing the load is located at the first closed end 1031 or approaches the first closed end 1031, the bearing capacity of the connecting portion 201 on the first connecting member 100 is stronger, the first member 500 can bear larger load, the connection stability is better, and therefore the technical problem that the bearing capacity of the first member 500 is insufficient or limited after the flat-push invisible connecting member is adopted in the prior art is solved. Meanwhile, the embodiment 1 of the present invention avoids the problem that the bearing capacity of the first member 500 is reduced due to the longitudinal groove formed in the surface of the first member 500, and also ensures the aesthetic property of the first member 500 to fit the aesthetic appearance of the user.

It should be noted that the longitudinal direction of this embodiment 1 is shown by an arrow Y in fig. 1 to 28, and the transverse direction of this embodiment 1 is shown by an arrow X in fig. 1 to 28, which are for illustrating the extending direction of the first channel 103 and the second channel 104 on the first connecting member 100, and are not used to limit the specific positions of the first channel 103 and the second channel 104, for example, the longitudinal direction may be a vertical direction, the transverse direction may be a horizontal direction, and the included angle between the longitudinal direction and the transverse direction is 90 °; for another example, the longitudinal direction may be a vertical direction, the transverse direction may be a direction gradually inclined downwards along a horizontal plane, and an included angle between the longitudinal direction and the transverse direction is less than 90 degrees; for another example, the longitudinal direction may be a vertical direction, the lateral direction may be a direction gradually inclined upward along a horizontal plane, and an angle between the longitudinal direction and the lateral direction is greater than 90 °. For another example, in some embodiments, the transverse direction is horizontal, and the angle between the longitudinal and transverse directions may be greater than or equal to or less than 90 °. For another example, the lateral direction is not a horizontal direction, the longitudinal direction is not a vertical direction, and an angle between the longitudinal direction and the lateral direction may be greater than or equal to or less than 90 °. Therefore, those skilled in the art can adapt the method according to the actual use situation.

Further, the first surface 101 and the second surface 102 may be a plane, an arc surface, a curved surface, a stepped surface, or the like, for example, when the first surface 101 is a stepped surface, the first channel 103 and the second channel 104 may be located on an upper surface and a lower surface of the stepped surface, respectively, and still be within the protection scope of the present invention.

For example, the first ledge 1032 is in a strip shape, one strip-shaped first ledge 1032 may be continuously disposed inside the first channel 103, or a plurality of strip-shaped first ledges 1032 may be intermittently disposed inside the first channel 103 in sequence. For another example, the first ledge 1032 is block-shaped or dot-shaped, and a plurality of block-shaped or dot-shaped first ledges 1032 are disposed inside the first channel 103 intermittently in sequence. As further described below with respect to the location of the first ledge 1032 in the first channel 103.

As an illustration of the location of the first ledge 1032 at the first channel 103, as shown in fig. 1-2, 4-11, 13-20, 23-28, the first channel 103 has a first inner sidewall 1033 extending in the transverse direction, at least one first ledge 1032 is disposed on the first inner sidewall 1033, and the first ledge 1032 extends in the transverse direction. The first channel 103 has two opposite first inner sidewalls 1033, and only one of the first inner sidewalls 1033 may be provided with at least one first ledge 1032 (as shown in fig. 4 and 10), or at least one first ledge 1032 may be provided on each of the two first inner sidewalls 1033 (as shown in fig. 1-2, 5-9, 11, 13-20, and 23-28). For example, a plurality of first rims 1032 may be disposed on the same first inner sidewall 1033, and the plurality of first rims 1032 are sequentially arranged at intervals in a direction perpendicular to the transverse direction, and each first rim 1032 may be continuously disposed on the first inner sidewall 1033 in the transverse direction. When the connecting portion 201 slides to the first passage 103, the connecting portion 201 abuts against the first ledge 1032 to limit the connecting portion 201 from being pulled out of the first passage 103, and at this time, the second connecting member 200 may not be located at the first closed end 1031, or may be located at or near the first closed end 1031, which is not limited herein.

Further, the first channel 103 also has a first bottom wall 1034 extending in the transverse direction. As shown in fig. 21, the side of the first ledge 1032 adjacent to the first closed end 1031 and opposite to the first bottom wall 1034 is set at a distance D1 from the first surface 101, and the side of the first ledge 1032 adjacent to the communication between the first passage 103 and the second passage 104 and opposite to the first bottom wall 1034 is set at a distance D2 from the first surface 101, wherein D1> D2. For example, the thickness dimension of the first ledge 1032 gradually increases in a direction toward the first closed end 1031 at the communication between the first passage 103 and the second passage 104, such that D1> D2; for another example, in the direction from the communication position of the first passage 103 and the second passage 104 to the first closed end 1031, the thickness dimension of the first ledge 1032 gradually increases after decreasing, and finally, D1> D2; for another example, in the direction from the communication position of the first passage 103 and the second passage 104 to the first closed end 1031, the thickness dimension of the first ledge 1032 is kept the same, and then gradually increased, and finally the thickness is kept the same, and finally D1> D2 is obtained. By means of D1> D2, the connecting portion 201 can be easily slid into the first passage 103 during sliding of the connecting portion 201 from the connection point of the first passage 103 and the second passage 104 to the first closed end 1031, then the connecting portion 201 gradually receives a pressing force between the first protruding edge 1032 and the first bottom wall 1034 during sliding of the first passage 103, and when the connecting portion 201 slides to the first closed end 1031 or approaches the first closed end 1031, the connecting portion 201 receives a larger pressing force between the first protruding edge 1032 and the first bottom wall 1034, so that the connecting portion 201 receives a larger friction force in the first passage 103, and the connecting portion 201 is stably fastened in the first passage 103, thereby further improving the connection stability of the first connecting member 100 and the second connecting member 200.

As another illustration of the position of the first ledge 1032 in the first passage 103, at least one first ledge 1032 is provided on the first closed end 1031. When the connecting portion 201 slides to the first closed end 1031 or approaches the first closed end 1031, the connecting portion 201 abuts against the first ledge 1032 to limit the connecting portion 201 from being pulled out of the first passage 103, so as to connect the first connecting member 100 and the second connecting member 200 to each other.

In other embodiments of this embodiment 1, as shown in fig. 12, the first channel 103 may not have the first ledge 1032 on the inner side, and the connection portion 201 is restricted from being pulled out of the first channel 103 by the high friction between the surface of the connection portion 201 and at least one first inner wall side to generate a clamping force, so as to connect the first connection member 100 and the second connection member 200 to each other.

Further, in some embodiments, as shown in fig. 1-2, 4-11, and 13-20, at least one first limit bump 1032a is disposed on the first ledge 1032 at a position close to the first closed end 1031, and the first limit bump 1032a is used to limit the connecting portion 201 of the second connecting member 200 at or near the first closed end 1031. The number of the first limiting protrusions 1032a may be one or more, and is not limited herein. For example, when only one inner sidewall is provided with the first ledge 1032, the first ledge 1032 may be provided with one or more first limiting protrusions 1032a, and a plurality of first limiting protrusions are sequentially provided on the first ledge 1032. For another example, when the two first inner sidewalls 1033 are respectively provided with the first protruding edges 1032, each of the first protruding edges 1032 may be provided with one or more first limiting protruding points 1032a, and the plurality of first limiting protruding points 1032a are sequentially provided on the same first protruding edge 1032. The first limiting convex points 1032a may have certain elasticity, for example, soft plastic or silica gel is used; the position-limiting convex points can also have no elasticity, such as hard plastics and the like. When the connecting portion 201 slides to the first limit salient point 1032a, the first limit salient point 1032a is subjected to a certain elastic deformation after being abutted by the connecting portion 201, and then the connecting portion 201 slides over the first limit salient point 1032a and is located at or close to the first closed end 1031, at this time, after the first limit salient point 1032a recovers to the original state, the connecting portion 201 is clamped at the first closed end 1031 or close to the first closed end 1031, so that the first connecting member 100 and the second connecting member 200 are connected, the first limit salient point 1032a is used for preventing the connecting portion 201 from easily displacing in the first channel 103 in the connecting state of the first connecting member 100 and the second connecting member 200, so that the stable connection of the first connecting member 100 and the second connecting member 200 is ensured, and meanwhile, the first member 500 is ensured to have a large carrying capacity.

In some embodiments, the end of the connecting portion 201 is attached to the first bottom wall 1034, so as to avoid a gap between the connecting portion 201 and the first bottom wall 1034 from affecting the stability of the connecting portion 201 in the first channel 103, and simultaneously increase the protruding length of the second connecting member 200 in the first slideway to improve the load-bearing capacity of the first member 500.

In some embodiments of this embodiment 1, as shown in fig. 1-2, the second channel 104 has a second inner sidewall 1043 extending along the longitudinal direction, and the second inner sidewall 1043 is provided with at least one second convex edge 1042. The second channel 104 has two opposite second inner sidewalls 1043, at least one second protruding edge 1042 (as shown in fig. 4-5 and 10) may be provided on only one of the second inner sidewalls 1043, or at least one second protruding edge 1042 (as shown in fig. 1-2, 6-11, 13-20 and 23-26) may be provided on each of the two second inner sidewalls 1043. For example, a plurality of second protruding edges 1042 may be disposed on the same second inner sidewall 1043, and the second protruding edges 1042 are sequentially spaced apart from each other in a direction perpendicular to the longitudinal direction, and each second protruding edge 1042 may be continuously disposed on the second inner sidewall 1043 in the longitudinal direction. When the connecting portion 201 slides in the second channel 104, the connecting portion 201 abuts against the second ledge 1042 to limit the connecting portion 201 from being pulled out of the second channel 104, so as to ensure that the connecting portion 201 slides into the first channel 103 after the second channel 104 slides.

In some embodiments, the first ledge 1032 is connected to the second ledge 1042.

Further, in some embodiments, as shown in fig. 1-2, 6-7, 10-11, 13-20, and 23-28, the second channel 104 has a second bottom wall 1044 extending in the longitudinal direction, and the first bottom wall 1034 is connected to the second bottom wall 1044, wherein the first bottom wall 1034 and the second bottom wall 1044 may be a plane or a cambered surface, and the first bottom wall 1034 and the second bottom wall 1044 may be in the same plane or not in the same plane, which is not limited herein. For example, during the sliding of the connecting portion 201 in the second channel 104, the end of the connecting portion 201 may be attached to the second bottom wall 1044.

In other embodiments, as shown in fig. 8-9, the second channel 104 does not have a second bottom wall 1044. The connecting portion 201 slides along the second inner sidewall 1043 of the second channel 104 to the first channel 103. Or, during the sliding process of the connecting portion 201 in the second channel 104, the connecting portion 201 abuts against the second convex edge 1042 and slides along the second convex edge 1042 into the first channel 103.

In some embodiments of this embodiment 1, as shown in fig. 1-2 and 4-28, the first surface 101 is provided with a first positioning step 1035 at a position close to the first closed end 1031. When the connecting portion 201 slides to the first closed end 1031 or approaches the first closed end 1031, the first positioning boss is used for abutting against a portion of the second connecting member 200 to perform a positioning function, so as to avoid abrasion caused by rigid collision between the connecting portion 201 and the first closed end 1031, and protect the first connecting member 100 or the second connecting member 200.

In some embodiments of this embodiment 1, as shown in fig. 1-2 and 4-28, an outer side surface of the first connecting member body near the first closed end 1031 is a circular arc surface. Because the surface of the first member 500 needs to be provided with the first mounting groove 501 for mounting the first connecting member 100, the outer side surface of the first connecting member body close to the first closed end 1031 is an arc surface, which can reduce the width of the first mounting groove 501 close to the first closed end 1031, so that the bearing capacity of the first member 500 is larger; meanwhile, the first member 500 is matched with the arc surface of the first closed end 1031 through the designed first mounting groove 501, so that the longitudinal bearing thickness of the first member 500 is relatively increased, and the first member 500 can bear larger longitudinal bearing capacity.

In embodiment 1 of the present invention, the communication between the first end 1045 of the second channel 104 extending in the longitudinal direction and the first channel 103 includes two cases, the first end 1045 of the second channel 104 extending in the longitudinal direction is communicated with the end of the first channel 103 extending in the transverse direction, and the second end 1045 of the second channel extending in the longitudinal direction is communicated with the middle of the first channel 103 extending in the transverse direction, which will be further described below.

As shown in fig. 1-2 and 4-22, when the first end 1045 of the second passage 104 extending in the longitudinal direction is communicated with one end of the first passage 103 extending in the transverse direction, the other end of the first passage 103 extending in the transverse direction is a first closed end 1031. The installation channel formed by the first channel 103 and the second channel 104 is approximately L-shaped. In some embodiments, as shown in fig. 1 to 2, 4, 8 to 17, 20 and 22, an outer corner 105 of a communication portion between the second channel 104 and the first channel 103 may be closed, and the closed outer corner 105 may improve the overall structural strength of the first connector 100 to improve the load-bearing capacity of the first member 500. Further, when the outer corner 105 of the communication position between the second channel 104 and the first channel 103 is closed, the outer side surface of the outer corner 105 of the first connecting member body, which is close to the communication position between the first channel 103 and the second channel 104, is an arc surface, so that the width of the first mounting groove 501, which is close to the outer corner 105, can be reduced, and the bearing capacity of the first member 500 is larger; meanwhile, the first member 500 is matched with the arc-shaped outer side surface of the second external corner 105 through the designed first mounting groove 501, so that the longitudinal bearing thickness of the first member 500 is relatively increased, and the first member 500 can bear larger longitudinal bearing capacity. In other embodiments, as shown in fig. 5 to 7, the outer corner 105 of the second channel 104, which is connected to the first channel 103, may be provided with one or more openings, which is not limited herein.

In some embodiments, when the first member 500 is connected to the second member 600, the first connector 100 may be mounted to one side of the first member 500, and the first member 500 may be pushed to move longitudinally and transversely with respect to the second member 600, so that the connecting portions 201 of the first connector 100 on the first member 500 and the second connector 200 on the second member 600 are connected to each other.

In some embodiments, when the second members 600 are connected to the left and right sides of the first member 500, two first connectors 100 may be installed on the left and right sides of the first member 500, respectively, and the first member 500 is pushed to move longitudinally and transversely with respect to the second member 600, so that the first connectors 100 on the left and right sides of the first member 500 are connected to the connecting portions 201 of the second connectors 200 on the two second members 600, respectively. When the installation channel formed by the first channel 103 and the second channel 104 is approximately L-shaped, as shown in fig. 1-2, the first connecting members 100 located on the left and right sides of the first member 500 need to have two symmetrical types, and the two first connecting members 100 need to be correspondingly installed on the left and right sides of the first member 500 during installation, so as to meet the requirement that the first connecting members 100 on the left and right sides of the first member 500 are respectively connected with the second connecting members 200 on the two second members 600 during the movement of the first member 500.

Further, as shown in fig. 1-2 and 4-22, a recessed portion is formed on the first surface 101 at a position below the outside of the first passage 103 and on the side of the outside of the second passage 104, so that the projection of the first connector body on the first surface 101 is approximately L-shaped. The recess portion can reduce the width of the first mounting groove 501 of the first member 500 corresponding to the first channel 103, thereby increasing the load-bearing capacity of the first member 500.

As shown in fig. 23-28, when the first end 1045 of the second passage extending along the longitudinal direction is connected with the middle part of the first passage 103 extending along the transverse direction, the two ends of the first passage 103 are respectively the first closed ends 1031 in the transverse direction; or, in the transverse direction, one end of the first passage 103 is a first closed end 1031, and the other end is provided with an opening. The installation channel formed by the first channel 103 and the second channel 104 is approximately T-shaped. Preferably, both ends of the first passage 103 in the transverse direction are respectively first closed ends 1031. When the second members 600 are connected to the left and right sides of the first member 500, the two first connectors 100 can be installed on the left and right sides of the first member 500, respectively, and the first member 500 is pushed to move longitudinally and transversely with respect to the second member 600, so that the first connectors 100 on the left and right sides of the first member 500 are connected to the connecting portions 201 of the second connectors 200 on the two second members 600, respectively. The mounting channel formed by the first channel 103 and the second channel 104 is approximately T-shaped, so that a user does not need to distinguish the left side and the right side of the first member 500 when mounting the first connecting member 100, the connecting part 201 of the second connecting member 200 can slide to one of the first closed ends 1031, the mounting is convenient and fast, the operation is rapid, and the assembly efficiency is greatly improved. Further, the two first closed ends 1031 are arranged in an axisymmetric manner with respect to the second channel 104, and when the first member 500 is driven to move laterally with respect to the two second members 600, the sliding distances of the left and right sides of the first member 500 are the same, thereby preventing the first member 500 from being skewed.

Further, as shown in fig. 23 to 28, a recessed portion is formed on the first surface 101 at a position below the outside of the first passage 103 and on the side of the outside of the second passage 104, so that the projection of the first connector body on the first surface 101 is approximately T-shaped. The recess portion can reduce the width of the first mounting groove 501 of the first member 500 corresponding to the first channel 103, thereby increasing the load-bearing capacity of the first member 500.

It should be noted that the communication between the first end 1045 of the second channel 104 extending along the longitudinal direction and the first channel 103 in the embodiment 1 of the present invention is not limited to the communication between the end portion of the first end 1045 of the second channel 104 extending along the longitudinal direction and the first channel 103, and also includes the end portion of the first end 1045 of the second channel 104 extending along the longitudinal direction passing through the first channel 103 to protrude out of the first channel 103 (as shown in fig. 18-19, and 27-28), that is, the first end 1045 of the second channel 104 extending along the longitudinal direction and the first channel 103.

The first connector body has a third surface 106 facing away from the first surface 101. In some embodiments, as shown in fig. 1-2, 4-8, 10, 12-16, 18, 23, 25, 27, the third surface 106 extends outwardly at a location corresponding to the first channel 103 to increase the distance between the first surface 101 and the third surface 106, thereby increasing the contact area of the first connector body with the inner side wall of the first mounting groove 501 of the first member 500 and thus increasing the load-bearing capacity of the first member 500. In some embodiments, the portion of the first connector body provided with the first passage 103 is stepped from the portion of the first connector body provided with the second passage 104.

In embodiment 1 of the present invention, the first connector body may be detachably or non-detachably mounted in the first mounting groove 501 of the first member 500.

As a solution for detachably mounting the first connector body on the first mounting groove 501, as shown in fig. 1-2, 4-8, 10, 12-14, 21, 23, and 27, at least one first mounting post 1061 is disposed on the third surface 106. The first mounting column 1061 may be a cylinder, a square body, a cone, a pyramid, or the like; the number of the first mounting posts 1061 may be one or more; the first mounting post 1061 may be made of a hard material, such as a hard plastic, or may be made of a soft material, such as a soft plastic, a silicon gel, or a rubber. Therefore, embodiment 1 of the present invention does not limit the specific shape, number and material of the first mounting posts 1061, and can be adaptively designed according to the actual use situation. 1-2, 4-8, 10, 12-14, 21, the number of first mounting posts 1061 is one; as shown in fig. 23 and 27, the number of the first mounting posts 1061 is two.

Accordingly, as shown in fig. 47, the bottom wall of the first mounting groove 501 of the first member 500 is opened with a first connection hole 5012 for mounting the first mounting post 1061. The number of the first connection holes 5012 is the same as that of the first mounting posts 1061, and the positions of the first connection holes 5012 in the first mounting groove 501 correspond to the positions of the first mounting posts 1061 on the first connector 100. The cross-sectional dimension of the first connection hole 5012 is smaller than the cross-sectional dimension of the first mounting post 1061, so that the first mounting post 1061 is fastened in the first connection hole 5012 by interference fit or elastic deformation compression. When the external force acting on the first connector 100 is greater than the sliding friction force of the first mounting post 1061 at the first connection hole 5012, the first connector 100 can be pulled out from the first mounting groove 501, so as to detach the first connector 100 from the first member 500. For example, after the first connector 100 is mounted in the first mounting groove 501, the third surface 106 can be attached to the bottom wall of the first mounting groove 501.

Further, as shown in fig. 1-2, 4-8, 10, 12, 14, 21, 23, 27, the outer surface of the first mounting post 1061 is provided with at least one first barb 1062. The number of first barbs 1062 may be one or more, for example, a plurality of first barbs 1062 are spaced in sequence along the length of the first mounting post 1061. The peripheral area of the first barb 1062 is larger than the cross-sectional area of the first connection hole 5012, so that when the first installation post 1061 is inserted into the first connection hole 5012, the first barb 1062 bends inward toward the outer surface of the first installation post 1061, and after being stationary, the first barb 1062 forms a large deformation tension on the inner side wall of the first connection hole 5012, thereby increasing the sliding friction between the first installation post 1061 and the first connection hole 5012, so that the first installation post 1061 is difficult to be removed from the first connection hole 5012. The first barb 1062 of embodiment 1 of the present invention may have flexibility or rigidity, for example, the flexible first barb 1062 can reduce the stress applied to the first member 500, so as to ensure that the structures of the first member 500 and the first connection hole 5012 are unchanged.

As another solution for detachably mounting the first connector body to the first mounting groove 501, as shown in fig. 13 to 15, at least one second barb 107 is disposed on an outer side wall of the first connector body. The number of the second barbs 107 may be one or more, for example, a plurality of second barbs 107 are sequentially arranged on the outer side wall of the first connector body at intervals. The shape and structure of the second barb 107 are similar to the shape and structure of the first barb 1062, and thus the description is omitted here. When the first connecting member 100 is inserted into the first mounting groove 501, the second barb 107 is bent inward toward the outer sidewall of the first connecting member body, and after the second barb 107 is stationary, a large deformation tension is formed on the inner sidewall of the first mounting groove 501, so that the sliding friction force between the first connecting member 100 and the first mounting groove 501 is increased, and the first connecting member 100 is difficult to move out of the first mounting groove 501. Further, the embodiment 1 does not limit the specific position of the second barb 107 on the first connector body, for example, the second barb 107 may surround the outer sidewall of the first connector body, or may be a part of the first connector body.

As another solution for detachably mounting the first connector body to the first mounting groove 501, as shown in fig. 16-19 and 25-26, the first connector body is provided with a first mounting hole 108. The first mounting hole 108 is a through hole structure, and may be connected to the first mounting groove 501 after passing through the first mounting hole 108 by using a threaded fastener such as a pin, a screw, or a bolt, and the first connecting member 100 and the first member 500 may be detached by detaching the threaded fastener such as the pin, the screw, or the bolt.

In addition, the first connecting member body of the embodiment 1 may be mounted in the first mounting groove 501 by gluing or riveting. Therefore, embodiment 1 of the present invention does not limit the installation manner of the first connecting member 100 in the first installation groove 501, and those skilled in the art can design the first connecting member adaptively according to the specific use situation.

In some embodiments of this embodiment 1, the first connecting member body is made of plastic, preferably rigid plastic, and has high overall structural strength and excellent bearing capacity. For example, the first connector body is formed into an integrated structure by adopting an injection molding process. In other embodiments, the first connector body may be made of metal or glass or other composite materials, which are not limited herein.

The specific structure of the second connector 200 of the present embodiment 1 will be further described below.

As shown in fig. 29 to 33, the second connector 200 of the present embodiment 1 includes a connecting portion 201 for connecting to the mounting passage, for example, the connecting portion 201 is an end portion of the second connector 200. The shape and structure of the connecting portion 201 are respectively adapted to the first passage 103 and the second passage 104, so that the connecting portion 201 can slide in from the first opening 1041 and slide relative to the first closed end 1031, and when the first connecting member 100 and the second connecting member 200 are in a connected state, the connecting portion 201 slides into the first passage 103. For example, the connection portion 201 may be slid to a middle portion of the first passage 103, and for example, the connection portion 201 may be slid to the first closed end 1031 or close to the first closed end 1031.

It should be noted that, the specific structure or shape of the second connecting element 200 is not limited in this embodiment 1, for example, the second connecting element 200 may be an existing conventional bolt, screw, or pin, the connecting portion 201 is a head of the bolt, screw, or pin, and the connecting portion 201 may abut against the first inner sidewall 1033 of the first channel 103 or abut against the first ledge 1032 to limit the connecting portion 201 from being pulled out of the first channel 103, so as to achieve connection between the first connecting element 100 and the second connecting element 200. As shown in fig. 29 to 30, the second connecting member 200 is a cylindrical or square column structure, the connecting portion 201 is provided with a locking step 202, and when the first ledge 1032 is provided on the inner side of the first channel 103, the locking step 202 abuts against the first ledge 1032 to limit the connecting portion 201 from being pulled out of the first channel 103. As shown in fig. 31 to 33, the second connector 200 is a cylindrical or square column, the connecting portion 201 is an end portion of the second connector 200, and the connecting portion 201 can abut against the first inner sidewall 1033 of the first channel 103 to limit the connecting portion 201 from being pulled out of the first channel 103. For another example, when both sides of the first member 500 are respectively used to connect the second members 600, the two first connectors 100 are respectively disposed on both sides of the first member 500, the connecting portion 201 of the second connector 200 on the second member 600 is located in the first channel 103 and attached to the inner side of the first channel 103 or has a certain gap therebetween, and the two second members 600 are used to clamp both sides of the first member 500 to restrict the movement of the first member 500 in the left-right direction, thereby realizing the connection between the first member 500 and the two second members 600.

In some embodiments, as shown in fig. 29-32, the second connector 200 is provided with a positioning portion 203 positioned in cooperation with the first positioning step 1035. For example, the positioning part 203 may have a disk shape surrounding the outer surface of the first connector 100, and the cross-sectional area of the positioning part 203 is larger than that of the second connector 200; for another example, the positioning portion 203 may be a bar or a block, and the peripheral edge of the positioning portion 203 is located outside the cross-sectional projection of the second connecting member 200. When the connecting portion 201 slides to the first sealing section or approaches the first sealing end 1031, the first positioning boss is abutted to the positioning portion 203 to perform a positioning function, so that abrasion caused by rigid collision between the connecting portion 201 and the first sealing end 1031 is avoided, and the first connecting member 100 or the second connecting member 200 is protected. In addition, the positioning part 203 is used to abut against the surface of the second member 600 to position the protruding height of the connection part 201 on the surface of the second member 600.

Further, the positioning portion 203 is attached to the first surface 101. When the connecting portion 201 slides to the first sealing section or is close to the first sealing end 1031, the positioning portion 203 is attached to the first surface 101, so that the tightness between the first connecting member 100 and the second connecting member 200 can be improved, the shaking caused by the gap is avoided, the connection stability between the first connecting member 100 and the second connecting member 200 is improved, meanwhile, the bearing capacity of the first member 500 is improved, and the appearance is good. When the connecting portion 201 is provided with the locking step 202, a sliding groove which is matched with the first protruding edge 1032 or the second protruding edge 1042 for sliding is formed between the positioning portion 203 and the locking step 202, wherein a distance D1 between a side of the first protruding edge 1032, which is close to the first closed end 1031 and opposite to the first bottom wall 1034, and the first surface 101 is less than or equal to a width of the sliding groove, and when the connecting portion 201 slides to the first closed end 1031 or approaches the first closed end 1031, the sliding groove is matched with the first protruding edge 1032 for clamping so that the connecting portion 201 is stabilized at the first closed end 1031 or approaches the first closed end 1031, thereby improving the connection stability of the first connecting member 100 and the second connecting member 200.

In some embodiments, the second connector 200 has a mounting portion 204 opposite the connecting portion 201, the mounting portion 204 being for connection to the second member 600. For example, as shown in fig. 29-31, the mounting portion 204 may be externally threaded, and the mounting portion 204 may be self-tapping or non-self-tapping; is attached to the second member 600. For example, as shown in fig. 32-313, the mounting portion 204 is a rod structure, the second member 600 has a slot, and the mounting portion 204 is fastened in the slot by interference fit or elastic clamping. Alternatively, the mounting portion 204 may be attached to the second member 600 by gluing or self-tapping. When the second connecting member 200 is mounted on the second member 600, the positioning portion 203 is attached to the surface of the second member 600, so that the tightness between the first connecting member 100 and the second connecting member 200 is further improved, the connection stability between the first connecting member 100 and the second connecting member 200 is improved, the bearing capacity of the first member 500 is improved, and the appearance is good. For another example, the mounting portion 204 is a polished rod structure, the second member 600 is provided with an insertion hole into which the mounting portion 204 is inserted, and a gap exists between the mounting portion 204 and the insertion hole; when two sides of the first member 500 are respectively used for connecting the second member 600, two first connectors 100 are respectively arranged on two sides of the first member 500, the connecting portion 201 of the second connector 200 on the second member 600 is positioned in the first channel 103, and the first member 500 is limited to move in the left-right direction through the connection between the connecting portion 201 and the first connector 100 and the relative constraint between the two second members 600, so that the connection between the first member 500 and the two second members 600 is realized.

In some embodiments, when the second inner sidewall 1043 of the second channel 104 is provided with the second protruding edge 1042 extending along the longitudinal direction, during the sliding process of the connecting portion 201 in the second channel 104, the locking step 202 abuts against the second protruding edge 1042 to limit the pulling-out of the connecting portion 201 from the second channel 104, so as to ensure that the connecting portion 201 slides into the first channel 103 after the sliding process of the second channel 104.

In some embodiments of this embodiment 1, the second connecting member 200 is made of metal, such as iron or steel or alloy, and has high structural strength to meet a large load-bearing requirement.

To prevent the connecting portion 201 from moving in the first channel 103 when the first connecting member 100 and the second connecting member 200 are in the connected state, in some embodiments, as shown in fig. 41 to 43, the connecting assembly of this embodiment 1 further includes a stopper 300, the stopper 300 having a third end 301 and a fourth end 302 opposite to each other; the stopper 300 is inserted into the second channel 104 from the first access hole 1041, the third end 301 of the stopper 300 is located at the communication position of the first channel 103 and the second channel 104, and at least a part of the stopper 300 abuts against the connecting portion 201 to limit the connecting portion 201 from sliding in the first channel 103.

In this embodiment 1, the specific structure or shape of the stopper 300 is not limited, and the structure or shape of the stopper 300 is adapted to the first access hole 1041. For example, as shown in fig. 41-43, when the second inner sidewall 1043 of the second channel 104 is provided with a second ledge 1042 extending along the longitudinal direction, the stop member 300 is stepped. For example, when the second inner sidewall 1043 of the second channel 104 does not have the second ledge 1042, the stop member 300 can be square or cylindrical.

Based on the structure of the connecting assembly, the first member 500 and the second member 600 can be connected by the connecting assembly to form a connecting system, as shown in fig. 44 to 56, which includes the first member 500, the second member 600, the first connecting member 100 and the second connecting member 200; a first mounting groove 501 is formed in a side surface of the first member 500, and one side of the first mounting groove 501 penetrates through a lower surface of the first member 500 to form a first mounting opening 5011; the first connector 100 is installed in the first installation groove 501, and the first surface 101 faces the notch of the first installation groove 501 and makes the first channel 103 and the second channel 104 communicate with the outside; the second passage 104 is communicated with the outside through the first access hole 1041 and the first mounting hole 5011 in sequence; the second connector 200 is mounted on the second member 600, and the connecting part 201 is arranged on the surface of the second member 600 in a protruding manner; the connecting portion 201 slides into the second passage 104 from the first mounting hole 5011 and the first opening 1041 in sequence, and the connecting portion 201 slides along the second passage 104 and slides into the first passage 103. The first member 500 is connected with the second member 600 by the connection portion 201 being located in the first passage 103 to connect the first connector 100 and the second connector 200 to each other. Because the first closed end 1031 is closed, the structural strength of the first closed end 1031 is greater than that of the middle part of the first passage 103 or other positions of the first passage 103, when the connecting portion 201 slides to the first closed end 1031 or approaches the first closed end 1031, the acting force of the first member 500 bearing the load is located at the first closed end 1031 or approaches the first closed end 1031, so that the bearing force of the first connecting member 100 on the connecting portion 201 is stronger, the first member 500 can bear larger load, and the connection stability is better. The embodiment 1 of the present invention avoids the problem that the bearing capacity of the first member 500 is reduced due to the transverse grooves formed on the surface of the first member 500, and thus solves the technical problem that the bearing capacity of the first member 500 is insufficient or limited after the flat push type invisible connector is adopted in the prior art. The aesthetic appearance of the first member 500 is ensured to conform to the aesthetic appearance of the user.

In some embodiments, the first surface 101 has a recess formed at a position below the outer portion of the first channel 103 and lateral to the outer portion of the second channel 104, so that the projection of the first connector body on the first surface 101 is approximately L-shaped. The recessed portion can avoid forming a longitudinal groove with a large length on the surface of the first member 500, reduce the size of the longitudinal groove and the first mounting hole 5011, and avoid the problem that the bearing capacity of the first member 500 is reduced due to the longitudinal groove, thereby increasing the bearing capacity of the first member 500. While ensuring the aesthetic appearance of the first member 500 to conform to the aesthetics of the user.

In some embodiments, a step shape is formed between the portion of the first connector body provided with the first channel 103 and the portion of the first connector body provided with the second channel 104, so as to avoid forming a longitudinal groove with a large depth dimension on the surface of the first member 500, reduce the dimensions of the longitudinal groove and the first mounting opening 5011, and avoid the problem that the bearing capacity of the first member 500 is reduced due to the longitudinal groove, thereby increasing the bearing capacity of the first member 500. While ensuring the aesthetic appearance of the first member 500 to conform to the aesthetics of the user.

Further, the connection system further includes a stopper 300, the stopper 300 is inserted into the second channel 104 from the first access hole 1041, the third end 301 of the stopper 300 is located at the communication position of the first channel 103 and the second channel 104, and at least a part of the stopper 300 abuts against the connection portion 201 to limit the connection portion 201 from sliding in the first channel 103, so that the connection portion 201 is prevented from moving in the first channel 103 when the first member 500 and the second member 600 are in the connection state, and the connection stability between the first member 500 and the second member 600 is improved.
