[0068] Figure 5 It is the schematic diagram of the shelf clamped on the supporting pin shaft of the utility model. Figure 6 It is the schematic diagram of the clamping process of the shelf on the supporting pin shaft of the utility model. Figure 7 It is the structural schematic diagram of one perspective of the shelf of the utility model. Figure 8 It is the structural schematic diagram of another perspective of the shelf of the utility model.

[0069] Referring to Figure 5 to Figure 6 The shelf can further comprise a shelf plate 200, which is supported on the supporting pin shaft 400 to limit the shelf plate 200 on the supporting rod 101. A plurality of clamping grooves 201 are formed on the bottom surface of the shelf plate 200, which are detachably clamped on the supporting pin shaft 400, so that the shelf plate 200 can be detachably arranged on the supporting pin shaft 400.

[0070] A plurality of supporting pin shafts 400 are penetrated in a plurality of supporting rods 101, and the shelf plate 200 is clamped on the supporting pin shaft 400 through the clamping groove 201. The supporting pin shaft 400 can be penetrated in the perforation 103 of different heights, so that the shelf plate 200 can be arranged at different heights. The supporting pin shaft 400 can be adjusted in position on the supporting rod 101 by the way of pulling and inserting, and the shelf plate 200 can be clamped and separated on the supporting pin shaft 400 by the way of pressing and lifting in the vertical direction. The operation of the supporting pin shaft 400 and the shelf plate 200 is simple, and the height of the shelf plate 200 can be conveniently adjusted.

[0071] The clamping groove 201 comprises a first sidewall 210 and a second sidewall 220 opposite to each other in the horizontal direction, and the first sidewall 210 and the second sidewall 220 are distributed on both sides of the supporting pin shaft 400 in the radial direction. The second sidewall 220 of the clamping groove 201 is an elastic rib capable of elastic deformation. The supporting pin shaft 400 is arranged between the first sidewall 210 and the second sidewall 220, and the elastic rib is capable of elastic deformation. The elastic rib is elastically compressed on the supporting pin shaft 400, so that the connection between the supporting pin shaft 400 and the shelf 200 is stable and reliable.

[0072] The elastic rib comprises a first section 221 and a second section 222 in the direction from top to bottom. In the direction from top to bottom, the first section 221 is arranged obliquely towards the first sidewall 210 of the clamping groove 201. In the direction from top to bottom, the second section 222 is arranged obliquely away from the first sidewall 210 of the clamping groove 201. The distance between the upper end of the first section 221 and the first sidewall 210 is greater than the diameter of the supporting pin shaft 400. The distance between the lower end of the first section 221 and the first sidewall 210 is less than the diameter of the supporting pin shaft 400.

[0073] The elastic rib is capable of elastic deformation. When the shelf 200 is installed, the shelf 200 is pressed downward, the supporting pin shaft 400 moves upward relative to the shelf 200, the lower end of the first section 221 is deformed by the pressing of the shelf 200, so that the supporting pin shaft 400 moves to between the first section 221 and the first sidewall 210, effectively limiting the disconnection between the supporting pin shaft 400 and the shelf 200. When the shelf 200 needs to be disassembled, the shelf 200 is lifted upward, the supporting pin shaft 400 drives the elastic rib to deform, so that the supporting pin shaft 400 and the shelf 200 are separated.

[0074] In the direction from top to bottom, the second section 222 is arranged obliquely away from the first sidewall 210 of the clamping groove 201, so that the opening of the clamping groove 201 gradually expands in the downward direction, facilitating the alignment of the clamping groove 201 and the supporting pin shaft 400, and facilitating the cooperation between the clamping groove 201 and the supporting pin shaft 400.

[0075] In some embodiments, the shelf 200 is a structure formed by sheet metal of a metal material; and the clamping groove 201 is a structure formed by bending from the shelf 200. The entire shelf 200 is a structure formed by sheet metal of a metal material, and the clamping groove 201 is formed by bending and stamping on the shelf 200. The clamping groove 201 is formed by bending the metal material, and the sidewalls of the clamping groove 201 are metal materials, so that the first section 221 and the second section 222 have elasticity.

[0076] In some embodiments, the shelf 200 is a structure formed by sheet metal, the shelf 200 includes an upper plate 230, a side plate 240, and a folding plate; the side plate 240 is a structure bent from the edge of the upper plate 230 and formed downward; the folding plate is a structure bent from the bottom end of the side plate 240; the folding plate is bent to form a clamping groove 201. The entire shelf 200 is formed by sheet metal to facilitate the rapid manufacturing of the shelf 200.

[0077] In some embodiments, the upper side wall of the clamping groove 201 is formed with a downward protruding abutting protrusion 202, the lower end of the abutting protrusion 202 abuts against one axial end of the support shaft 400. The abutting of the abutting protrusion 202 at one axial end of the support shaft 400 can limit the axial movement of the support shaft and prevent the support shaft from being pulled out of the hole.

[0078] In some embodiments, the clamping groove 201 is a structure formed by sheet metal, and the abutting protrusion 202 is a structure formed on the clamping groove 201 by stamping.

[0079] It should be noted that in some embodiments, the shelf 200 is a structure formed of plastic or wood.

[0080] In some embodiments, the support rod 101 is provided as four, and the four support rods 101 are sequentially connected; the shelf 200 is a rectangular structure, and a notch 203 is formed at the corner of the shelf 200, and the edge of the notch 203 abuts against at least two adjacent sides of the support rod 101 to limit the horizontal movement of the shelf 200.

[0081] In some embodiments, the support rod 101 is provided as six, and the support rods 101 are provided as a support group 110. The support group 110 is provided as three groups. The shelf 200 is provided with six notches 203 corresponding to the shelf 200, and the edge of the notch 203 abuts against the support rod 101 to limit the horizontal movement of the shelf 200.

[0082] The shelf 200 is provided with one or more groups on the support frame 100; the multiple groups of shelves 200 are vertically spaced. By adjusting the height of different shelves 200, the distance between the shelves 200 can be adjusted.

[0083] Based on the above structure, when the height of the shelf 200 needs to be adjusted, the shelf 200 is lifted upward so that the shelf 200 and the support pin shaft 400 are separated. The corresponding support pin shaft 400 is pulled out of the support rod 101, and then the support pin shaft 400 is inserted into the perforation 103 of the corresponding height. The shelf 200 is moved above the support pin shaft 400, and the clamping groove 201 and the support pin shaft 400 are opposite, and the shelf 200 is pressed downward, so that the clamping groove 201 is clamped on the support pin shaft 400.
