Description

Technical Field

[0001] The utility model belongs to the technical field of pallets, and in particular relates to a pallet with stable placement. Background Art

[0002] Pallets are the medium that transforms static cargo into dynamic cargo. They are a loading platform, a movable platform, or, in other words, a movable surface. Even cargo that would otherwise lose its mobility when placed on the ground becomes mobile once loaded onto a pallet. This is because cargo on a pallet is always ready for movement. This dynamic loading and unloading method, using pallets as a fundamental tool, is called pallet handling.

[0003] At present, most of the existing pallets are planar structures. When stacking pallets, many pallets need to be stacked together. Due to the lack of connection structure between adjacent pallets, the pallets are prone to sliding, resulting in unstable placement and the risk of slipping. Utility Model Content

[0004] The purpose of the present invention is to provide a stable tray to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a stably placed pallet, comprising a pallet and a connecting mechanism, the connecting mechanism comprising a connecting block fixedly arranged at the bottom of the pallet and a connecting groove opened at the top of the pallet, there are four connecting blocks and four connecting grooves, the four connecting blocks and the connecting grooves are evenly divided into two groups and respectively arranged at both ends of the pallet, a locking hole is opened inside the connecting block, a cavity is opened inside the pallet between two connecting grooves on the same side, a bidirectional screw is rotatably installed in the cavity, both ends of the bidirectional screw are threadedly connected to a screw tube, the end of the screw tube away from the bidirectional screw is fixedly connected to a locking rod, and the middle of the bidirectional screw is connected to a drive assembly.

[0006] As a preferred embodiment, a plurality of evenly distributed reinforcement strips are fixedly connected to the interior of the pallet.

[0007] As a preferred embodiment, the drive assembly includes a handle, a worm and a worm wheel, the handle is fixedly connected to the end of the worm, the worm is rotatably installed in the cavity, and the worm wheel is fixedly connected to the middle of the bidirectional screw and engages with the worm.

[0008] As a preferred embodiment, grooves are provided at both ends of the tray, and the handles are provided in the grooves.

[0009] As a preferred embodiment, both ends of the tray are hinged with cover plates for covering the grooves.

[0010] As a preferred embodiment, a limiting groove is provided on the inner wall of the cavity, and a limiting block is provided at the bottom of the spiral tube, and the limiting block slides in the limiting groove.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The stable pallet is provided with a connection mechanism. When the pallets are stacked, the connection block of the upper pallet can be inserted into the connection groove of the lower pallet. Then, the driving assembly is used to rotate the bidirectional screw, so that the bidirectional screw drives the screw tube to move, and the screw tube drives the locking rod to insert into the locking hole of the connection block, thereby connecting adjacent pallets together, avoiding sliding between the pallets, preventing the pallets from overheating, and reducing the risk of slipping.

[0013] The stably placed tray is provided with a driving assembly. During operation, the handle can be rotated to control the rotation of the worm, so that the worm drives the worm wheel to rotate, and the worm wheel drives the bidirectional screw to rotate, which is convenient to operate.

Simple improvements to the method of the present invention based on the concept of the present invention fall within the scope of protection claimed by the present invention.

[0020] See also Figure 1-3The utility model provides a stably placed pallet, including a pallet 1 and a connecting mechanism 2. A plurality of evenly distributed reinforcement strips 11 are fixedly connected to the interior of the pallet 1. The arrangement of the reinforcement strips 11 can reinforce the pallet 1 and improve the structural strength of the pallet 1.

[0021] The connecting mechanism 2 includes a connecting block 21 fixedly arranged at the bottom of the tray 1 and a connecting groove 22 opened at the top of the tray 1. There are four connecting blocks 21 and four connecting grooves 22. The four connecting blocks 21 and the connecting grooves 22 are evenly divided into two groups and are respectively arranged at the two ends of the tray 1. A locking hole 23 is opened inside the connecting block 21. A cavity is opened inside the tray 1 between the two connecting grooves 22 on the same side. A bidirectional screw 24 is rotatably installed in the cavity. Both ends of the bidirectional screw 24 are threadedly connected to a screw tube 25. The end of the screw tube 25 away from the bidirectional screw 24 is fixedly connected to The locking rod 26 and the middle part of the bidirectional screw 24 are connected with a driving assembly 27. Through the setting of the connecting mechanism 2, when the pallets 1 are stacked, the connecting block 21 of the upper pallet 1 can be inserted into the connecting groove 22 of the lower pallet 1, and then the bidirectional screw 24 can be rotated by the driving assembly 27, so that the bidirectional screw 24 drives the screw tube 25 to move, and the screw tube 25 drives the locking rod 26 to be inserted into the locking hole 23 of the connecting block 21, connecting adjacent pallets 1 together, avoiding sliding between the pallets 1, preventing the pallets 1 from overheating, and reducing the risk of slipping.

[0022] Specifically, the drive assembly 27 includes a handle 271, a worm 272 and a worm wheel 273. The handle 271 is fixedly connected to the end of the worm 272, and the worm 272 is rotatably installed in the cavity. The worm wheel 273 is fixedly connected to the middle of the bidirectional screw 24 and engages with the worm 272. Through the setting of the drive assembly 27, during operation, the handle 271 can be rotated to control the rotation of the worm 272, so that the worm 272 drives the worm wheel 273 to rotate, and the bidirectional screw 24 is driven to rotate by the worm wheel 273, which is convenient to operate.

[0023] Among them, grooves 12 are opened at both ends of the tray 1, and the handle 271 is arranged in the groove 12. Both ends of the tray 1 are hinged with cover plates 13 for covering the groove 12.
