[0002] In the warehousing industry, the use of shelving is becoming increasingly widespread, and its practical application is expanding. Many valuable or dangerous items are also stored on shelves, which places higher demands on their safety, especially in the event of an earthquake. This requires that goods must be securely fixed to the shelves. Previous designs have involved applying non-slip rubber to the crossbeams to increase friction between the pallet and the crossbeams, or using simple baffles for guidance. These measures can only prevent pallets from falling off the shelves during minor shakes, but cannot address the potential for pallets to fall during significant shakes. Utility Model Content

[0020] Example 1

[0021] like Figure 1 and Figure 2As shown, in this embodiment, a position limiting clamping device includes a support 1 and a clamp 2. The clamp 2 is made by casting or cutting and welding. The support 1 is upwardly open and includes a space for accommodating the clamp. The clamp is directly placed in the support. A groove is provided on the side wall of the support. The clamp includes a connecting portion 21, a pressing portion 23 and a clamping portion 24. The connecting portion 21 is provided with an eccentric pin 22. The eccentric pin 22 is installed in the groove on the side wall of the support, and the connecting portion 21 rotates relative to the support with the eccentric pin 22 as the rotating axis. One end of the connecting portion 21 is fixedly connected to the pressing portion 23, and the other end of the connecting portion 21 is connected to the clamping portion 24. The pressing portion 23 and the clamping portion 24 extend in the same direction starting from the connecting portion 21. The clamping portion 24 is longer than the pressing portion 23, and a clamping tooth 25 extending toward the pressing portion is provided at the end of the clamping portion. When the clip 2 is in the first state, the end of the connecting portion 21 connected to the pressing portion 23 is higher than the end connected to the clamping portion 24, and the upper end of the pressing portion 23 is higher than the upper top surface of the support 1. When the tray leg 3 falls directly and the pressing portion 23 is subjected to force, the connecting portion 21 rotates around the eccentric pin shaft 22, the pressing portion 23 moves downward, and the clamping portion 24 moves upward and toward the pressing portion 23, and the clamping teeth 25 clamp the side of the tray leg 3.

[0022] like Figure 3 As shown, the lower end surface of the clamping tooth is an inclined surface extending outward and upward from the clamping portion. When the clamp is clamped from the top of the pallet leg, the inclined surface is conducive to not interfering with the pallet leg when the pallet is lifted, thereby preventing the limit clamping device from getting stuck.

[0023] The shelf includes a support beam 4, which is provided with a groove for installing a support. The support beam 4 and the support 1 are made by cutting a rectangular tube, and the support beam and the support are welded into one body.

[0024] Example 2

[0025] like Figures 4 to 8As shown, in this embodiment, a limit clamping assembly includes a support 1 and two clips 2. The support 1 is open upward and includes a space for accommodating the clips. A groove is set on the side wall of the support. The clip 2 includes a connecting portion 21, a pressing portion 23 and a clamping portion 24. The connecting portion 21 is provided with an eccentric pin 22. The eccentric pin 22 is installed in the groove of the side wall of the support, and the connecting portion 21 rotates relative to the support 1 with the eccentric pin 22 as the rotating axis. One end of the connecting portion 21 is fixedly connected to the pressing portion 23, and the other end of the connecting portion 21 is connected to the clamping portion 24. The pressing portion 23 and the clamping portion 24 start from the connecting portion 21 at the same time. The clamping portion 24 is longer than the pressing portion 23, and a clamping tooth 25 extending toward the pressing portion is provided at the end of the clamping portion. The two clips 2 are symmetrically installed in the space of the support. When the clip 2 is in the first state, the end of the connecting portion 21 connected to the pressing portion 23 is higher than the end connected to the clamping portion, and the upper end of the pressing portion is higher than the upper top surface of the support. When the tray leg 3 falls directly and the pressing portion 23 is subjected to force, the connecting portion 21 rotates around the eccentric pin shaft 22, and the pressing portion 23 moves downward. The clamping portions 24 of the two clips move upward and approach each other, and the clamping teeth 25 of the two clips clamp the object to be limited.

[0026] like Figure 9 As shown, the lower end surface of the clamping tooth is an inclined surface extending outward and upward from the clamping portion. When the clamp is clamped from the top of the pallet leg, the inclined surface is conducive to not interfering with the pallet leg when the pallet is lifted, thereby preventing the limit clamping device from getting stuck.

[0027] like Figure 10 As shown, the shelf includes a support beam 4, the support beam 4 is provided with a groove for installing a support, the support beam and the support are made by cutting a rectangular tube, and the support beam and the support are welded into one body.

[0028] Figure 6 and Figure 7 The diagrams are as follows: the process of the pallet legs falling and the diagram after they have fallen. Due to gravity, the clamps automatically open after they are placed in the support. When the pallet is lowered and placed, the pallet legs press against the bottom of the clamps. Due to the lever principle, the clamps rotate and move from the outside to the inside. When the pallet is completely placed on the support beam, the clamps clamp the sides of the pallet legs, thus securing the pallet legs. Figure 7 When the goods need to be taken, the forklift lifts the goods upwards, and the clamps automatically open to both sides due to their own gravity, and the goods are taken out.
