Description

TECHNICAL FIELD

[0001] The application relates to the field of plastic pallets, in particular to a plastic pallet with built-in limiting function. BACKGROUND

[0002] The plastic pallet is a kind of container widely used in logistics, warehousing, industrial production and other fields, which is made of plastic material. Compared with traditional wooden and metal pallets, it has unique advantages. In the process of loading, unloading, carrying and transporting goods, the plastic pallet can be used as a carrying tool for goods, and can be used with forklifts, pallet carriers and other equipment to realize the rapid transfer of goods and improve the logistics efficiency.

[0003] In addition, the existing patent No. CN219601858U discloses a plastic pallet with built-in limiting function. However, the device has some shortcomings in actual use.

[0004] The device limits the top goods by the limiting frame. Since the size of the fixed frame cannot be adjusted and the height cannot be adjusted, the fixing effect is not good enough, and the limitation is too high. Therefore, the present application provides a plastic pallet with built-in limiting function. CONTENT OF THE UTILITY MODEL

[0005] In order to improve the problem that the goods stacked on the pallet have no limiting at the bottom and are not stable enough, the application provides a plastic pallet with built-in limiting function.

[0006] The application provides a plastic pallet with built-in limiting function, which adopts the following technical scheme:

[0007] A plastic pallet with built-in limiting function, comprising a pallet body, a limiting sliding groove is symmetrically formed on the top of the pallet body, a rectangular hole is symmetrically formed in the middle of the bottom of the pallet body, a fixed block is symmetrically fixedly connected to the rectangular hole, an extrusion block is movably penetrated through the two fixed blocks and inserted into the rectangular hole, a rectangular slot is formed in the middle of the two extrusion blocks, a binding strap is abutted to the bottom of the two extrusion blocks and is slidably connected to the limiting sliding groove, and a sliding block is fixedly connected to the two ends of the two binding straps and is slidably connected to the limiting sliding groove.

[0008] By adopting the above technical scheme, when the goods extrude the extrusion block to move downward, the extrusion block will lift the binding strap to tighten, thereby driving the sliding block in the limiting sliding groove to shrink inward, so as to drive the fixing device on the top to tighten, thereby achieving the functions of limiting and fixing.

[0009] Preferably, a circular groove is formed in the middle of the top of the fixed block, a fixed rod is movably penetrated through the middle of the bottom of the circular groove, and a compression spring C is sleeved on the outer peripheral surface of the fixed rod and abuts against the fixed rod and the fixed block at both ends.

[0010] By adopting the technical scheme, the compression spring C can provide a vertical force on the extrusion block, and the circular groove can provide a containing cavity after the compression spring C is contracted.

[0011] Preferably, both ends of the fixed rod are in abutment with both ends of the rectangular groove.

[0012] By adopting the technical scheme, the connection of the fixed rod and the rectangular groove can make the extrusion block be always lifted by the force of the compression spring C without external extrusion.

[0013] Preferably, the top end of the sliding block is fixedly connected with a clamping plate that is slidingly connected with the top of the tray body.

[0014] By adopting the technical scheme, the clamping plate can be contracted when the sliding block moves inward, thereby playing a fixing role.

[0015] Preferably, a limiting groove is symmetrically formed in the inner side of the clamping plate, a limiting column is movably penetrated in the middle of the bottom end of the limiting groove, one end of the limiting column is fixedly connected with an auxiliary plate that is matched with the clamping plate, and a compression spring A is sleeved on the outer peripheral surface of the limiting column and abuts against the auxiliary plate and the clamping plate at both ends.

[0016] By adopting the technical scheme, the auxiliary plate can move with the clamping plate, thereby playing a limiting and fixing role, the auxiliary plate and the clamping plate can be combined, the compression spring A cooperates with the limiting column to make the auxiliary plate can be adjusted in position, thereby improving the size range of the goods clamping.

[0017] Preferably, an insertion slot is symmetrically formed in the top of the auxiliary plate, and two insertion plates A are inserted in the two insertion slots, and the top end of the insertion plate A is fixedly connected with a limiting baffle.

[0018] By adopting the technical scheme, the installation of the limiting baffle can vertically increase the limiting height.

[0019] Preferably, two insertion plates B are inserted in the two insertion slots, the top end of the two insertion plates B is fixedly connected with a horizontal plate, two hinge seats A are hinged to the horizontal plate, one side of the two hinge seats A is fixedly connected with a limiting rod, the limiting rod is movably penetrated in a limiting block, and a compression spring B is sleeved on the outer peripheral surface of the limiting rod and abuts against the limiting block and the hinge seat A at both ends.

[0020] By adopting the technical scheme, the horizontal plate can be combined with the auxiliary plate into a whole through the insertion plate B, and the combination of the hinge seat A, the limiting rod, the limiting block and the compression spring B can play a role of adjusting the contraction distance.

[0021] Preferably, one end of the two limiting blocks is fixedly connected with a hinge seat B, and two extrusion plates are hinged to the hinge seat B.

[0022] By adopting the technical scheme, the extrusion plate can be combined with the horizontal plate to form a whole after being extruded, so as to be clamped and fixed and to play a limiting role.

[0023] In summary, the present application has at least one of the following beneficial technical effects:

[0024] 1. When the goods are placed on the top of the tray body, the extrusion block moves downward under the gravity of the goods, drives the binding belt to move inward, and in turn drives the auxiliary plate and other components to move inward together. The inner side of the auxiliary plate is attached to the bottom of the goods and generates extrusion force. This automatically generated extrusion force is equivalent to limiting the goods from the bottom, which makes up for the lack of limiting the bottom of the goods on the tray in the past, so that the goods are placed more stably on the tray, effectively preventing the goods from sliding or toppling on the tray.

[0025] 2. When the goods are narrow, the auxiliary plate may not be able to completely fit the bottom of the goods. At this time, the auxiliary plate and the horizontal plate are combined into a whole through the insertion plate B, which extends the clamping range horizontally, so that the tray can better fit each position of the bottom of the goods and provide more comprehensive bottom support and limiting. If the goods are high, the insertion plate A is inserted on the auxiliary plate to fix the limiting baffle, which enhances the stability in the vertical direction. BRIEF DESCRIPTION OF DRAWINGS
