The buckle base comprises a through hole arranged along the first direction, a second through groove arranged along the second direction and a buckle slide rail extending to the second through groove along the second direction. The second through groove is matched with the first end of the fastener body in the second direction. The snap assembly is configured to: in the process that the fastener slides along the fastener slide rail, the fastener body shields the through hole and the elastic limiting piece is inserted into the second through groove, or the through hole is exposed through the first through groove and the elastic limiting piece is separated from the second through groove.

The latch included in the latch assembly will be described in detail with reference to fig. 1A to 1B. Wherein, fig. 1A schematically shows the structural schematic diagram of the first angle of the fastener in the buckle assembly according to the embodiment of the present invention, and fig. 1B schematically shows the structural schematic diagram of the second angle of the fastener in fig. 1A.

As shown in fig. 1A to fig. 1B, a fastening element 100 of the embodiment of the present invention includes a fastening element body 110 and an elastic limiting element 120.

The fastener body 110 has a first through groove 111 disposed along the first direction (Z-axis direction), and the first through groove 111 may be, for example, a rectangular groove or a circular groove, and the shape of the first through groove 111 is not limited. The elastic limiting member 120 protrudes from the fastener body 110 in the first direction, and extends in the second direction. Wherein the second direction is a direction (Y-axis direction) perpendicular to the first direction.

Specifically, the elastic limiting element 120 may extend from the first end 112 to the second end 115 of the fastener body 110, wherein an end of the elastic limiting element 120 close to the first end 112 is fixedly connected to the fastener body 110, and a portion of the elastic limiting element 120 close to the second end 115 is an elastic portion, and under an external force, the elastic portion may be compressed along a direction opposite to the Z direction, so that the elastic limiting element 120 is in a compressed state, and after the external force is released, the elastic portion may rebound along the Z direction, so that the elastic limiting element 120 returns to an uncompressed state. According to an embodiment of the present invention, the elastic limiting member 120 and the fastening member body 110 can be, for example, an integrally formed structure.

According to an embodiment of the present invention, as shown in fig. 1A, the elastic limiting element 120 may specifically include two sets of limiting elements symmetrically disposed with respect to the first through groove 111.

In consideration of the fact that the body structure of the latch body 110 between the first through groove 111 and the elastic limiting member 120 is small, the latch body is easily broken by external force. In order to improve the stability of the locking element body 110, as shown in fig. 1A, a first rib 113 may be disposed between the elastic limiting element 120 and the first through groove 111 of the locking element body 110. The first stiffener 113 protrudes from the fastener body 110, and the first stiffener 113 and the elastic limiting member 120 protrude toward the same side of the fastener body 110. According to the embodiment of the present invention, the first stiffener 113 may be, for example, a rectangular structure, a trapezoidal structure or an arbitrary structure, and the first stiffener 113 may also protrude out of the buckle body in the Z-axis direction in the negative direction, which is not limited by the present invention. As long as the first reinforcing rib is arranged to increase the thickness of the fastener body 110 between the first through groove 111 and the elastic limiting member 120 in the Z direction.

In consideration of the fact that the elastic portion of the elastic limiting member 120 may be broken due to an excessive external force during the compression process of the elastic limiting member 120 under the external force. As shown in fig. 1B, in order to improve the external force bearing capability of the elastic limiting member 120, a second rib 121 may be disposed on a surface of the elastic limiting member perpendicular to the protruding direction (positive direction of the Z axis) and close to the latch body 110, specifically, the second rib 121 is disposed on a surface of the elastic portion of the elastic limiting member 120 away from the Z direction. The second reinforcing rib 121 may have a structure similar to that of the elastic limiting member 120, or may have any structure as long as the second reinforcing rib 121 is provided to increase the thickness of the elastic limiting member 120 in the Z direction.

In order to ensure that the through hole of the buckle base is completely blocked after the buckle 100 is inserted into the second through groove of the buckle base, and to realize stable connection between the buckle 100 and the buckle base, it is also required to ensure that the elastic portion of the elastic limiting member 120 can completely enter the second through groove. Therefore, the position of the insertion of the snap 100 into the second through groove needs to be defined. As shown in fig. 1A, the fastening member body 110 of the embodiment of the present invention is further provided with a limiting partition plate 114, the limiting partition plate 114 can extend outwards (i.e. extend along the positive and negative directions of the X axis) along the side wall 1111 of the first through groove 111 far away from the first end 112, and the limiting partition plate 114 should be disposed between the elastic limiting member 120 and the second end 115 of the fastening member body 110, i.e. the elastic limiting member 120 is disposed between the limiting partition plate 114 and the first end 112 of the fastening member body 110. Meanwhile, in order to limit the sliding of the latch 100 during the sliding process of the latch 100, the limiting diaphragm 114 should also protrude from the latch body 110 in the first direction (Z-axis direction). Further, the limiting partition 114 may protrude from the fastening element body 110 in the same direction as the protruding direction of the elastic limiting element 120, and the limiting partition 114 may also protrude from the elastic limiting element 120 in the non-compressed state in the protruding direction. Then, in the process that the fastening element 100 slides along the fastening slide rail of the fastening base, when the limiting partition 114 is attached to the side wall of the base forming the second through groove 220, the limiting partition can play a role of limiting the fastening element 100 from further sliding, so as to limit the position of the fastening element 100 when being fixedly connected with the fastening base.

According to an embodiment of the present invention, as shown in fig. 2A, the surface of the locking element body 110 facing away from the elastic limiting element 120 includes a first sub-surface 1161, the first sub-surface 1161 includes the surface between the extending tail portion 122 of the elastic limiting element 120 and the first end 112 of the locking element body 110, and an included angle between the first sub-surface and the first direction (specifically, the positive direction of the Z axis) is less than or equal to 90 °. In consideration of the possibility that the latch 100 may be caught during the sliding process along the latch slide rail of the latch base, the latch 100 may not slide smoothly. In order to solve the above problem, as shown in fig. 2A, a portion of the latch body 110 from the middle region to the first end 112 may be provided with a chamfer structure, which is far away from the elastic limiting member 120 in the Z-axis direction. For example, assuming that the elastic stopper protrudes from the upper surface of the latch body 110 in the Z-axis direction, the chamfer structure is disposed on the lower surface of the latch body 110 in the Z-axis direction. The angle of the first sub-surface to the first direction is preferably acute.

According to the embodiment of the present invention, in order to avoid the phenomena such as warping after the fastener 100 is installed and matched with the fastener base, the bottom surface (the surface facing away from the elastic limiting member 120) of the portion of the fastener body 110 that is not inserted into the second through groove of the fastener base should be kept flush, i.e. perpendicular to the Z-axis. Therefore, the surface of the latch body 110 facing away from the elastic limiting element 120 should further include a second sub-surface 1162. The second sub-surface includes a surface between the sidewall 1111 of the first through groove 111 far from the first end 112 and the second end 115, and the second sub-surface 1162 is perpendicular to the first direction.

According to the embodiment of the present invention, in consideration of the fact that the structure of the buckle body 110 between the first end 112 and the sidewall of the first through groove 111 near the first end 112 is narrow in the Y-axis direction due to the arrangement of the first through groove 111, the buckle body may be broken due to a large force when the first end 112 is inserted into the second through groove of the buckle base. Namely, the latch body 110 provided with the first through groove 111 has a defect of insufficient structural strength. Therefore, in order to improve the structural strength of the fastener body 110, as shown in fig. 1B, the fastener body 110 may further include a third reinforcing rib 117 on the surface extending from the first through groove 111 to the first end in the first sub-surface, and the third reinforcing rib 117 may be set in a plurality of and set to any structure according to actual requirements, which is not limited herein.

According to the embodiment of the present disclosure, in order to facilitate fixing of a fixing member such as a screw, as shown in fig. 2A, a specific example of the through hole 210 may be a screw fixing hole. The screw fixing hole may be composed of a groove matched with the screw cap and a fixing hole provided in the groove. The fixing hole is formed through the snap base 200 in the Z-axis direction, and a screw thread may be provided in the fixing hole for screwing a screw. According to the embodiment of the present invention, in order to facilitate the installation of the fixing member in the through hole 210 when the fastening member 100 exposes the through hole 210 of the fastening base 200 through the first through hole 111, the size of the first through hole 111 of the fastening member body 110 in fig. 1A to 1B should not be too small. Meanwhile, in order to ensure the aesthetic appearance of the whole structure, the size of the first through groove 111 should not be too large, because the larger size of the first through groove 111 inevitably makes the whole structure of the fastener 100 too large. Therefore, the dimension of the first through groove 111 in the direction perpendicular to the first direction (Z-axis direction) may be set to a dimension larger than 10mm and smaller than 15mm, for example. Specifically, the distance between any two points on the edge perpendicular to the first direction of the first through groove 111 should be greater than 10mm and less than 15 mm. It is understood that the size of the first through groove is only used as an example to facilitate understanding of the present invention, and the present invention is not limited thereto.

In this application scenario, in order to avoid the situation that the top plate flange deforms due to a large force in the process of fixing the fixing member to the top plate through the through hole 210, the distance between the through hole 210 and the side wall of the top plate close to the top plate flange is not too large, that is, the distance between the through hole 210 and the side wall (the side wall far away from the through hole 210 in the Y-axis direction, where the second through groove 220 is provided) of the fastening base 200, which is attached to the top plate, is not too large. Meanwhile, in order to facilitate the installation and fixation of the fixing member, the distance between the through hole 210 and the side wall of the top plate close to the top plate flange is not too small. That is, the distance between the end of the latch base 200 close to the second through-hole 220 in the Y-axis direction and the center axis of the through-hole 210 should not be too large or too small. For example, the distance between one end of the buckle base 200 close to the second through groove 220 and the central axis of the through hole 210 should be greater than or equal to 5mm and less than or equal to 20 mm. It is understood that the application scenario of the above-mentioned buckle assembly and the distance between the through hole 210 and one end of the buckle base 200 are only used as examples to facilitate understanding of the present invention, and the present invention is not limited thereto.
