DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0021] Please refer to Figures 1 to 5 The present application provides the following technical solutions: a storage rack for plastic pallets, comprising telescopic frame bodies 2 for limiting and supporting the stacked pallets 1, the telescopic frame bodies 2 are fixed to each other through connection plates 3, the lower part of the telescopic frame bodies 2 is slidingly connected with a base 4, the base 4 is bolted to the ground, and the base 4 is provided with a transmission mechanism 5 for controlling the telescopic frame bodies 2 to slide along the base 4, thereby limiting or unlocking the stacked pallets 1;

[0022] The driving column 6 is provided on the side of the transmission mechanism 5 and is provided with a spiral slot 7 on the surface. The two ends of the driving column 6 are rotatably connected to the inner wall of the base 4 with torsion springs. The forklift drives the transmission mechanism 5 to displace and drive the driving column 6 to rotate. The rotation of the driving column 6 pulls the telescopic frame 2 to displace to the two sides to release the limiting support on the stacked trays 1.

[0023] Referring to Figure 1 and Figure 2 , the telescopic frame 2 includes a limiting frame 21 and a supporting frame 22. The supporting frame 22 is an L-shaped structure. The limiting frame 21 and the supporting frame 22 are connected by a connecting plate 3. The telescopic frame 2 is provided with a locking mechanism.

[0024] The connecting plate 3 is provided with a locking mechanism of the telescopic frame 2, thereby controlling the expansion length of the telescopic frame 2, avoiding excessive occupation of vertical storage space, and simultaneously adjusting the height of the telescopic frame 2 to match the stacking structure while stacking the trays 1. The L-shaped structure of the limiting frame 21 can effectively limit the rear end of the tray 1, so that all the rear ends of the trays 1 are at the same horizontal position during the stacking operation.

[0025] As another embodiment, as shown in Figures 2 to 5 , a plurality of slide grooves 41 are formed on the upper surface of the base 4. The supporting frame 22 and the limiting frame 21 are slidably connected to the base 4 through the slide grooves 41.

[0026] The supporting frame 22 and the limiting frame 21 are slidably connected to different slide grooves 41, respectively. The limiting frames 21 and the supporting frames 22 on the same side are connected by the connecting plate 3. When the supporting frame 22 is driven to displace along the slide groove 41, the limiting frame 21 is simultaneously driven to displace by the connecting plate 3, thereby realizing the limiting support and unlocking of the telescopic frame 2 on the stacking structure.

[0027] During the stacking operation, the two supporting frames 22 are pulled away from each other. Then the first tray 1 is placed on the base 4. The supporting frames 22 are loosened. The supporting frames 22 automatically approach each other to limit the tray 1. Then the trays 1 are inserted in order according to the gap between the supporting frames 22 to realize the stacking of the trays 1. It should be noted that the rotatable connection between the driving column 6 and the inner wall of the base 4 is provided with a torsion spring. Under the action of the torsion spring, the driving column 6 always tends to rotate, thereby causing the supporting frames 22 to automatically approach each other after being loosened, thereby limiting the stacking structure.

[0028] Referring to Figure 3 , the transmission mechanism 5 includes a rack 51, a gear 52, and a driving assembly 53. The supporting frame 22 is fixedly connected to the rack 51 through the slide groove 41. The gear 52 is fixedly connected to the middle part of the driving column 6. The gear 52 is engaged with the rack 51.

[0029] In the initial state, the end of the two groups of racks 51 is in contact, and the two groups of support frames 22 are in the closest state. When the support frame 22 is pulled, the support frame 22 drives the rack 51 to move apart. When the support frame 22 is released, the driving column 6 is driven to rotate by the torsional spring, the gear 52 is driven to rotate, the rack 51 is horizontally displaced by the rotation of the gear 52, and the support frames 22 are driven to approach each other.

[0030] Referring to Figure 3 , to Figure 5 , the driving assembly 53 comprises a through hole 531, a push plate 532, a sliding rod 533, and a driving rod 534. The through hole 531 is formed on the upper part of the base 4. The sliding rod 533 is in sliding connection with the through hole 531. The upper end of the sliding rod 533 is in insertion connection with the push plate 532. One end of the driving rod 534 is in insertion connection with the side part of the lower end of the sliding rod 533. The other end of the driving rod 534 is inserted into the spiral slot 7. The driving rod 534 is in sliding connection with the driving column 6 through the spiral slot 7.

[0031] After the stacking operation is completed, when forklift transportation is needed, the forklift wall is inserted between the supporting legs of the lowermost tray 1. The push plate 532 is pushed to slide backward along the through hole 531. The push plate 532 drives the sliding rod 533 to slide, and then drives the driving rod 534 to slide backward. Through the limiting of the spiral slot 7, the driving rod 534 drives the driving column 6 to rotate in the movement. The rotation of the driving column 6 drives the gear 52 to rotate, and then drives the rack 51 to displace, so that the two groups of support frames 22 drive the limiting plates to move away from each other at the same time, thereby releasing the limiting of the stacked structure. The forklift can normally take out all the trays 1 at the same time for transportation.

[0032] The through hole 531 is perpendicular to the sliding groove 41. The through hole 531 and the push plate 532 are positioned between the supporting legs of the tray 1.

[0033] Referring to Figure 2 and Figure 4 , the rear end of the sliding rod 533 is provided with a locking pin. The rear end of the inner wall of the base 4 is provided with a clamping groove 42. The rear end of the clamping groove 42 is provided with an unlocking pedal 43.

[0034] When the forklift pushes the push plate 532 to the rear end, the locking pin on the sliding rod 533 is inserted into the clamping groove 42 to be locked, so that the sliding rod 533 can no longer displace. Through the limiting of the driving rod 534 on the driving column 6, the driving column 6 cannot be driven to rotate by the torsional spring, so that the support frames 22 cannot approach each other again to limit the stacked structure during the process of taking out the stacked structure by the forklift. The locking pin can be unlocked through the unlocking pedal 43 at the rear end of the base 4. The clamping structure of the locking pin and the clamping groove 42 can adopt a spring buckle or other conventional technical structure that can achieve the technical effect. The unlocking pedal 43 can adopt a rotating type unlocking structure that pushes the locking pin or other conventional technical structure that can achieve the technical effect.

[0035] Working principle: in use, pull the two sides of the support frame 22 sliding away from each other, then put the first tray 1 on the base 4, loosen the support frame 22, the support frame 22 automatically close to each other to limit the tray 1, then insert the tray 1 in order according to the stacking sequence; when the forklift transportation is needed, the forklift wall is inserted between the supporting legs of the lowermost tray 1, the push plate 532 slides backward along the through hole 531, the push plate 532 drives the rod 534 to slide backward, the driving column 6 is driven to rotate through the limiting of the spiral slot 7, and then the rack 51 is displaced, so that the two groups of support frames 22 drive the limiting plates to move away from each other at the same time, the limiting of the stacking structure is released, and the forklift can normally take out all the trays 1 at the same time for transportation.

[0036] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
