Description

Technical Field

[0001] This utility model relates to the field of logistics and transportation technology, specifically to a logistics turnover rack. Background Technology

[0002] Logistics turnover racks are tools used in the logistics process, mainly placed in warehouses, logistics centers, factory workshops, and other places. They have a multi-layered structure, come in different specifications and styles, and can be customized according to actual needs. Their function is to classify, organize, and temporarily store goods, facilitating the handling, loading, unloading, and inventory of goods, improving the efficiency of goods storage and circulation, and making logistics operations more orderly and standardized. However, when stacking spare turnover racks, the existing turnover rack design uses a fixed connection between the side panels and the pallets. This fixed connection structure results in relatively large gaps between turnover racks when stacked. These large gaps not only directly increase the overall space occupied after stacking, but also greatly reduce the utilization rate of storage space, affecting the space utilization rate of warehouses.

[0011] The above technical solution can effectively achieve stable locking of the upper side panel, thereby ensuring that the foldable side panel maintains high stability and safety during use and avoiding shaking or loosening during use.

[0012] As a preferred embodiment of this utility model, the ends of the two limiting sliders away from the moving sleeve extend into the interior of the two limiting slide grooves and are slidably connected to the inner wall of the limiting slide grooves. The structures of the four sets of locking components are all the same.

[0013] As a preferred embodiment of this utility model, the four support legs include support square tubes fixedly connected to the four corners of the tray.

However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and complete.

[0027] For examples, please refer to Figure 1-4 This utility model provides a technical solution:

[0028] The logistics turnover rack includes a pallet 1. Each of the four corners of the pallet 1 is equipped with a support leg 2. Foldable side panels 4 are symmetrically arranged on both sides of the pallet 1. Each foldable side panel 4 includes a lower side panel 401 symmetrically arranged on both sides of the top of the pallet 1. An upper side panel 402 is arranged above each of the two lower side panels 401. Rotating support columns 403 are fixedly connected to the front and rear ends of each of the two upper side panels 402. Locking components 5 for fixing the upper side panels 402 are provided at the ends of the two lower side panels 401 and the upper side panels 402 on the adjacent sides. Support rods 3 are welded to the center of the four sides of the bottom of the disk 1. The locking assembly 5 includes a bearing 501 connected to the top of the outer wall of the lower side plate 401. A U-shaped connecting frame 503 is welded to the bottom of the outer wall of the upper side plate 402. A connecting rod 502 is rotatably connected to the inner side of the bearing 501 via a pin. Slots 504 are opened on both the front and rear sides of the U-shaped connecting frame 503. A connecting cylinder 505 is fixedly connected to one outer wall of the U-shaped connecting frame 503. A fixed outer cylinder 506 is fixedly connected to the other outer wall of the U-shaped connecting frame 503.

[0029] The shaft seat 501 and the lower side plate 401 are welded together. The U-shaped connecting bracket 503 is located directly above the shaft seat 501. The top end of the connecting rod 502 can extend to the inside of the U-shaped connecting bracket 503. A rotary knob 507 is provided on the side of the fixed outer cylinder 506 away from the U-shaped connecting bracket 503. The outer wall of the rotary knob 507 is evenly distributed with anti-slip ridges. A drive screw 508 is provided on the inside of the fixed outer cylinder 506. One end of the drive screw 508 passes through the fixed outer cylinder 506 away from the U-shaped connecting bracket 503. One end of the connecting frame 503 is fixedly connected to the center of the rotating knob 507. The surface of the drive screw 508 is rotatably connected to the inner wall of the fixed outer cylinder 506 near the rotating knob 507. A movable sleeve 509 is sleeved on the outside of the drive screw 508. The inner wall of the movable sleeve 509 has an internal thread. The movable sleeve 509 is threaded to the outer wall of the drive screw 508 through the internal thread. The other end of the movable sleeve 509 extends to the outside of the fixed outer cylinder 506 and passes through the U-shaped connecting frame. 503. The connecting rod 502 is inserted into the inside of the connecting cylinder 505. The two ends of the movable sleeve 509 near the drive screw 508 are fixedly connected to the limiting sliders 510. The inner walls of the two sides of the fixed outer cylinder 506 are symmetrically provided with limiting grooves 511. The ends of the two limiting sliders 510 away from the movable sleeve 509 extend into the two limiting grooves 511 and are slidably connected to the inner walls of the limiting grooves 511. The four sets of locking components 5 have the same structure. The movable sleeve 509 can move in a straight line away from the fixed outer cylinder 506 under the driving action of the drive screw 508 and the guiding action of the limiting sliders 510 and the limiting grooves 511. The movable sleeve 509 passes through the connecting rod 502 and is inserted into the inside of the connecting cylinder 505. It can lock the upper side plate 402 with the U-shaped connecting frame 503 to achieve stable support for the upper side plate 402, thereby ensuring that the foldable side plate 4 maintains a high degree of stability and safety during use.

[0030] The four support legs 2 include support square tubes 201 fixedly connected to the four corners of the tray 1. The four support square tubes 201 are divided into two groups on the left and right sides respectively. Each group of support square tubes 201 has a connecting groove 203 on the side that is close to each other. Each group of support square tubes 201 has a connecting support leg 202 fixedly connected to the bottom end. The front and rear ends of the two lower side plates 401 are fixedly connected to the outer walls of the two groups of support square tubes 201 respectively. The four rotating support columns 403 are inserted into the four support square tubes 201 respectively. The four rotating support columns 403 are rotatably connected to the four support square tubes 201 through pins.

[0031] Among them, the upper side panel 402 is flipped downward to a horizontal state to achieve the folding of the side panel, which reduces the overall height during the stacking of turnover racks, reduces the space occupied by the logistics turnover racks when not in use, and greatly saves storage space.

[0032] Furthermore, the movable sleeve 509 locks the U-shaped connecting frame 503 to the connecting rod 502 through the connecting rod 502, thereby fixing the upper side plate 402 and ensuring that the logistics turnover rack has good structural stability and load-bearing capacity during use.

[0033] The working process of this utility model is as follows: In use, the upper side plate 402 is flipped to a vertical position, and the connecting rod 502 is flipped and extended to the inside of the U-shaped connecting frame 503. Then, the drive screw 508 is rotated using the rotary knob 507. During the rotation of the drive screw 508, the moving sleeve 509, under its driving action and guided by the limiting slider 510 and the limiting groove 511, moves in a straight line away from the fixed outer cylinder 506. The moving sleeve 509 passes through the connecting rod 502 and is inserted into the inside of the connecting cylinder 505. The U-shaped connecting frame 503 can lock the upper side plate 402, thereby achieving stable support for the upper side plate 402 and ensuring the stability of the logistics turnover rack during use. The system exhibits excellent structural stability and load-bearing capacity. Furthermore, when the logistics turnover rack needs to be folded and stored, simply reverse the rotation knob 507 to rotate the drive screw 508 and move the movable sleeve 509 towards the side closer to the fixed outer cylinder 506 until the movable sleeve 509 disengages from the connecting cylinder 505. At this point, the connecting rod 502 can be flipped out from the inside of the U-shaped connecting frame 503, and the upper side plate 402 can be flipped downwards to a horizontal state, thus folding the side plate and greatly saving storage space. The design of the connecting groove 203 in this utility model not only facilitates the connection and fixation between the supporting square tubes 201, but also provides additional stability and support for the logistics turnover rack.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art and are also general components, which are common knowledge in this field.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
