One side of the first positioning portion 43 is integrally connected with the vertical portion 41 to ensure structural stability. The bottom of the mating fastener 3 is provided with a first positioning groove 31 that is positioned in cooperation with the first positioning portion 43. When the mating fastener 3 is mated with the supporting fastener 4, the mating fastener 3 is at least partially hidden in the mounting groove 11, and the first positioning portion 43 is buckled and fitted in the first positioning groove 31.

[0028] The utility model installs the matching fasteners 3 on the shelf 1 and the supporting fasteners 4 on the side vertical plates 2. When the shelf 1 is installed in the cabinet body, the matching fasteners 3 are directly used to match and connect with the supporting fasteners 4, so that the shelf 1 and the side vertical plates 2 are fastened together to complete the installation of the shelf 1, thereby eliminating the need to tighten the screws in the cabinet body to lock the shelf 1, thereby achieving the purpose of improving the installation efficiency. At the same time, the installation grooves 11 are used to cover and hide the matching fasteners 3 and the supporting fasteners 4, reducing the chances of the matching fasteners 3 and the supporting fasteners 4 being exposed to the outside and damaged by external forces, thereby ensuring the service life of the matching fasteners 3 and the supporting fasteners 4, and allowing the shelf 1 to be firmly installed on the side vertical plates 2.

[0029] As a preferred embodiment, the side riser 2 is provided with a vertical plate screw hole 21, and the vertical portion 41 is provided with a vertical plate connecting hole 40. The vertical plate connecting hole 40 is penetrated by a vertical plate screw 5 that is threadedly engaged with the vertical plate screw hole 21. The vertical plate screw 5 is used to secure the support fastener 4 to the side riser 2. Furthermore, a horizontal positioning portion 44 is provided on the other side of the vertical portion 41. The side riser 2 is provided with a horizontal positioning hole 22 that cooperates with the horizontal positioning portion 44 to better align the vertical plate connecting hole 40 with the vertical plate screw hole 21, thereby facilitating the vertical plate bolt to mount the support fastener 4 on the side riser 2.

[0030] In this embodiment, the vertical plate connection holes 40 are disposed transversely through the transverse positioning portions 44. The transverse positioning holes 22 and the vertical plate screw holes 21 are sequentially arranged and correspondingly connected along the insertion direction of the vertical plate screws 5, thereby enabling rapid positioning of the support fasteners 4 on the side risers 2. Furthermore, the vertical plate connection holes 40 are countersunk to accommodate the heads of the vertical plate screws 5, thereby preventing them from interfering with the installation of the mating fasteners 3.

[0031] As a preferred embodiment, the mating fastener 3 is provided with a vertical connecting hole 32, and there are at least two vertical connecting holes 32 that are horizontally arranged along a straight line. The top wall of the mounting groove 11 is provided with a layer screw hole 111 corresponding to the vertical connecting hole 32, and each vertical connecting hole 32 corresponds to a layer screw hole 111, and each vertical connecting hole 32 is inserted with a layer bolt threadedly connected to the layer screw hole 111, so that the mating fastener 3 is fixed in the mounting groove 11 by using the layer bolt.

[0032] In this embodiment, the top protrusion of the mating fastener 3 is provided with a vertical positioning protrusion 33, and the top wall of the mounting groove 11 is provided with a vertical positioning groove 112 that cooperates with the vertical positioning protrusion 33. When the mating fastener 3 is engaged in the mounting groove 11, the vertical positioning protrusion 33 is inserted into the vertical positioning groove 112, achieving initial positioning of the mating fastener 3. The mating fastener 3 is then fixed in place using the deck bolts. Specifically, there are two vertical connection holes 32, and the vertical positioning protrusion 33 is located between the two vertical connection holes 32. Furthermore, the vertical connection hole 32 is a countersunk hole to conceal the head of the deck screw and prevent the head of the deck screw from interfering with the transverse portion 42.

[0033] In this embodiment, the cross-sectional shapes of the first positioning portion 43 and the first positioning groove 31 are both isosceles trapezoids with widths gradually decreasing from bottom to top, so that the first positioning portion 43 can be inserted into the first positioning groove 31 to improve the assembly efficiency of the layer board 1.

[0034] In this embodiment, the top wall of the first positioning groove 31 is provided with a downwardly protruding second positioning portion 311, and the top wall of the first positioning portion 43 is provided with a second positioning groove 431 that cooperates with the second positioning portion 311 for positioning, thereby further improving the positioning effect between the mating fastener 3 and the supporting fastener 4. Furthermore, the second positioning groove 431 is formed by a concave arc surface, and the second positioning portion 311 includes a convex arc surface that adapts to the concave arc surface. The convex arc surface forms an insertion end that facilitates the insertion of the second positioning portion 311 into the second positioning groove 431, thereby improving assembly efficiency.

[0035] In this embodiment, the top wall of the first positioning groove 31 is provided with a downwardly protruding third positioning portion 312, and the top wall of the first positioning portion 43 is provided with a third positioning groove 432 that cooperates with the third positioning portion 312 for positioning, thereby further improving the positioning effect between the mating fastener 3 and the supporting fastener 4. Specifically, the lower end of the third positioning portion 312 is a guide tip, and the bottom of the third positioning groove 432 is located in the tip matching groove adapted by the guide tip, thereby improving the efficiency of the third positioning portion 312 being inserted into the third positioning groove 432.
