[0009] In this invention, the outer end of the upper or lower surface of the protruding block is provided with an anti-detachment protrusion or an anti-detachment recess.

[0010] In this utility model, a spring is provided on the upper inner surface of the locking part. The spring abuts against the bottom surface of the cavity. The spring drives the locking part to rotate, causing the protruding latch to lock onto the support position of the support bar, so that the shelf buckle is fixed on the corresponding position on the support bar. The locking buckle is fastened to the buckle body to achieve self-locking.

[0011] In this utility model, the upper inner surface of the locking part is provided with a mounting post. The mounting post is a cylinder with a relief plane on its circumferential surface. The relief plane extends along the length direction of the mounting post. One end of the spring is interference-fitted to the mounting post, and the spring deforms towards the relief plane and clamps the mounting post under the compression of the mounting post.

[0012] In this invention, the opening of the mounting groove is provided with a Z-shaped locking rod or a rotating locking buckle to seal the opening of the mounting groove, thereby confining the outer frame support of the shelf within the mounting groove.

[0013] Secondly, this utility model also provides a snap-fit ​​assembly, including the aforementioned shelf snap-fit ​​with high locking performance and a support strip. The support strip is provided with a plurality of support slots, which are spaced apart along the length of the support strip. The snap-fit ​​body of the shelf snap-fit ​​is mounted on the support strip and can move along the length of the support strip.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0018] like Figure 1-6 As shown in the figure, the shelf buckle with high locking performance described in this embodiment of the present invention includes a buckle body 100. The buckle body 100 is provided with a mounting groove 101, which is used to install the shelf, specifically for placing the outer frame support of the shelf in the mounting groove 101. The buckle body 100 is also provided with a cavity 102, which is located below the mounting groove 101. A rocker-type locking part 103 is assembled in the cavity 102. Specifically, the locking part 104 is provided with a rotating connecting seat 108, and is rotatably mounted in the cavity 102 by means of a rotating shaft 124 passing through the rotating connecting seat 108.

[0019] The inner surface of the lower end of the locking part 103 (i.e. the part located below the rotating connecting seat 108) is provided with protruding latches 104 and locking buckles 105 arranged at intervals from top to bottom. In use, the shelf latches are installed on the support bar 200 to form a latch assembly. The support bar 200 is provided with a plurality of support slots 201, which can be one of the through holes or recesses provided on the surface of the support bar 200, and are distributed at intervals along the length of the support bar 200. The buckle body 100 of the shelf buckle is installed on the support bar 200 and can move along the length of the support bar 200. The locking part 103 is engaged with one of the support slots 201, so that the buckle body 100 is locked on the support bar 200. The locking buckle 105 is an inverted buckle and is engaged with the buckle body 100. Specifically, it can be engaged with the locking block 116 provided on the lower edge of the buckle body 100 to realize the locking of the locking part 103.

[0020] Furthermore, as the load-bearing capacity of the shelf reaches a certain weight and gradually increases, the protruding latch 104 gradually moves away from the support bar 200. Simultaneously, under the restraining effect of the locking buckle 105 fastened to the latch body 100, the locking portion 103 between the protruding latch 104 and the locking buckle 105 protrudes and deforms away from the support bar 200, thereby causing the locking buckle 105 to press against the latch body 100 under the restoring force of the locking portion 103. Specifically, the protruding latch 104 has a lower surface 106 that gradually slopes upwards towards the support bar 200. Preferably, the slope angle of the lower surface 106 is 0–5° (excluding 0°). The locking portion 103 has an elastic deformation section 107 located between the protruding latch 104 and the locking buckle 105. That is, the lower end of the locking portion 104 located below the rotating connecting seat 108 has the protruding latch 104 and the locking buckle 105. 5. An elastic deformation section 107 is provided; wherein, the inner surface of the locking part 103 between the protruding block 104 and the locking buckle 105 is provided with an arc-shaped recess 109, so that the elastic deformation section 107 is formed between the protruding block 104 and the locking buckle 105; when the load on the shelf gradually increases, the lower surface 106 of the protruding block 104 slides relative to the support position 201 of the support bar 200, so that the protruding block 104 gradually moves away from the support position 201 within a limited range. At the same time, under the action of the locking buckle 105, the elastic deformation section 107 protrudes and deforms away from the support bar 200 within a limited range. Then, by using the restoring force of the elastic deformation section 107, the locking buckle 105 is driven to abut and fasten against the locking block 116 of the buckle body 100, thereby improving the locking performance of the locking part 103 and making the shelf buckle have high locking performance on the support bar 200.

[0021] like Figure 3-5As shown, to ensure that the protruding latch 104 does not detach from the support slot 201 as it gradually moves away from the support slot 201, an anti-detachment protrusion 118 is provided at the outer end of the upper surface 117 of the protruding latch 104. The anti-detachment protrusion 118 preferably has a gradually upward-extending protruding surface, achieving both anti-detachment and ensuring that the protruding latch 104 can smoothly engage with the support slot 201. Alternatively, the anti-detachment protrusion 118 can be one or more protrusions or dots on the upper surface 117, or it can be replaced by a strip-shaped anti-detachment slot (groove). The anti-detachment protrusion 118 or anti-detachment slot hooks onto the support slot 201, for example, by hooking the edge of a through hole. The shelf buckle of this invention can also have an anti-detachment protrusion or anti-detachment slot (groove) at the outer end of the lower surface of the protruding latch 104.

[0022] like Figure 1 , 3 As shown in Figure 5, a spring 110 is provided on the inner surface of the upper end of the locking part 103 (i.e., the part located above the rotating connecting seat 108). The spring 110 abuts against the bottom surface of the cavity 102. Specifically, a mounting post 111 is provided on the inner surface of the upper end of the locking part 103. The mounting post 111 is a cylinder, and its circumferential surface is provided with a clearance plane 112. The clearance plane 112 extends along the length direction of the mounting post 111. One end of the spring 110 passes through the mounting post 111. The spring 110 is deformed towards the relief plane 112 under the compression of the mounting post 111, clamping the mounting post 111. This enhances the assembly connection strength and ensures the stability and reliability of the connection between the spring 110 and the mounting post 111 during the assembly process, which is beneficial for the automated assembly of the shelf clips. The bottom surface of the cavity 102 is provided with a spring mounting recess 113. When the locking part 103 is assembled in the cavity 102, the other end of the spring 110 is assembled in the spring mounting recess 113. The spring 110 drives the locking part 103 to rotate, causing the protruding locking block 104 to lock onto the support locking position 201 of the support bar 200, thus fixing the shelf clips to the corresponding positions on the support bar 200.

[0023] Furthermore, the opening of the mounting groove 101 described in this utility model is provided with a Z-shaped locking rod 114 or a rotating locking buckle 115 to seal the opening of the mounting groove 101, thereby confining the outer frame support of the shelf within the mounting groove 101. The specific structure can be as follows: Figure 1 , 25. The buckle body 100 is provided with a Z-shaped locking rod 114 at the opening of the mounting groove 101. The Z-shaped locking rod 114 is rotatably and vertically mounted on the buckle body 100. The locking crossbar 119 of the Z-shaped locking rod 114 can rotate to cross the mounting groove 101 and lock upwards, thereby restricting and locking the shelf (i.e., the outer frame support of the shelf) placed in the mounting groove 101 within the mounting groove 101. Or as... Figure 6 The mounting groove 101 opening is also provided with a rotating locking buckle 115. The rotating locking buckle 115 has a first locking plate 120 and a second locking plate 121, and a shelf mounting slot 122 is formed between the first locking plate 120 and the second locking plate 121. The rotating locking buckle 115 is rotatably mounted on a notch 123 provided on the side wall of the mounting groove 101. When installing the shelf, the shelf (outer frame support) is placed in the shelf mounting slot 122 and acts on the second locking plate 121, driving the rotating locking buckle 115 to rotate, so that the first locking plate 120 blocks the opening of the mounting groove 101, restricting the shelf (outer frame support) placed in the mounting groove 101, and locking the buckle body 100 by the movable locking part 125 on the rotating locking buckle 115.

[0024] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
