[0032] See also Figures 1 to 3The pallet is fixed to the outer frame 1 and the second reinforcing rod 3 is fixed between the front and rear inner walls of the outer frame 1, and the support block 4 is fixed to the outer frame 1 and the bottom surface of the second reinforcing rod 3, four pallets 5 installed between the inner walls of the outer frame 1, a mounting mechanism provided on the outer frame 1 and an auxiliary mechanism provided on the outer frame 1. When in use, the four pallets 5 are fixed by the outer frame 1, and then materials are stacked on multiple pallets 5. The outer frame 1 is supported by the support block 4, which makes it convenient for a forklift to lift the entire outer frame 1. The first reinforcing rod 2 and the second reinforcing rod 3 are provided, which is beneficial to improving the structural support strength. The pallet 5 is fixed and installed by the provided mounting mechanism, so that it is convenient to replace the pallet 5 when it is damaged, avoiding the waste of the entire pallet, reducing the cost of enterprise use, improving the utilization rate of resources, and having better practicality and being more convenient for promotion and use.

[0033] It should be noted that the outer frame 1 and the support plate 5 are both high-strength plastic injection moldings, which are a mature and public technology in the prior art, so the specific processing method thereof will not be described in detail herein.

[0034] The outer frame 1 is a square annular frame, and there are nine support blocks 4 that are evenly distributed at the bottom of the outer frame 1. Grooves are provided on the top surface of the first reinforcing rod 2 and the bottom surface of the second reinforcing rod 3. The first reinforcing rod 2 and the second reinforcing rod 3 are connected in a cross shape. The support plate 5 is a square grid plate. By setting the support plate 5 as a grid plate, it is beneficial to reduce the material used in the plate and reduce the weight of the structure.

[0035] See also Figures 1 to 3The mounting mechanism includes support bars 601 fixed to the inner walls on the left and right sides of the outer frame 1 and the left and right sides of the second reinforcing rod 3, a mounting chamber 602 fixed to the inner walls on the front and rear sides of the outer frame 1 and the front and rear sides of the first reinforcing rod 2, two sliders 603 slidably connected to the inside of the mounting chamber 602, a limiting block 604 fixed to the opposite sides of the two sliders 603, a mounting spring 605 fixed to the opposite sides of the two sliders 603 and a fixing block 606 fixed to the opposite sides of the two mounting springs 605, the fixing block 606 is fixed to the inner wall of the mounting chamber 602, a card slot 608 is provided on the front and rear sides and the left and right sides of the support plate 5, a limiting slot 609 is provided in the support plate 5 and on the left and right sides of the card slot 608, a toggle rod 607 is fixed to the bottom surface of the slider 603, and the mounting chamber 60 2 is provided with a movable hole for the toggle rod 607 to pass through and slide left and right inside it, and sliding holes for the limit blocks 604 to pass through are provided on the left and right sides of the installation bin 602. When in use, the four support plates 5 are used to stack materials. When a support plate 5 is damaged, the toggle rod 607 drives the slider 603 to slide inside the installation bin 602, and then the slider 603 drives the limit blocks 604 to disengage from the limit groove 609 and store them in the installation bin 602. At this time, the damaged support plate 5 can be removed from the outer frame 1 for replacement. When replacing a new support plate 5, align the slot 608 on its bottom surface with the installation bin 602 and the support bar 601 and put it down. Then, the installation spring 605 pushes the slider 603 to reset and drives the limit blocks 604 to be inserted into the limit groove 609 for fixation.

[0037] See also Figure 4 In this embodiment, the auxiliary mechanism includes four baffles 701 slidably connected to the top surface of the outer frame 1, an extrusion block 702 slidably connected to the inside of the baffle 701, a return spring 703 fixed to the top surface of the extrusion block 702, and a guide rod 704 fixed to the bottom surface of the extrusion block 702. The top surface of the outer frame 1 is provided with a receiving groove 705 for the baffle 701 to slide up and down. The bottom end of the guide rod 704 is fixed to the inner bottom wall of the receiving groove 705. The baffle 701 is provided with three movable grooves 705 for the extrusion block 702 to slide up and down. 6. When stacking materials, stack them on the inner side of the four baffles 701, and the baffles 701 are activated to prevent the materials from slipping. When the trays are not in use, multiple trays are stacked directly. The support block 4 on the top tray will squeeze the baffle 701, causing it to slide downward inside the storage slot 705, and at the same time, the squeezing block 702 will slide upward inside the movable slot 706 and compress the reset spring 703 to complete the storage. When the top tray is removed, the reset spring 703 pushes the baffle 701 to cooperate with the guide rod 704 to move up and reset.

[0038] In this embodiment, the baffle 701 and the receiving groove 705 are both shaped structures and the two are clearance-matched. The four baffles 701 are respectively arranged at the four corners of the top surface of the outer frame 1. The top of the reset spring 703 is fixed to the inner top wall of the movable groove 706. The bottom surface of the baffle 701 is provided with a guide hole that is connected to the movable groove 706 and is used for the guide rod 704 to pass through.

[0039] The working principle of the above embodiment is:

[0040] (1) When in use, materials are stacked by four pallets 5. When a pallet 5 is damaged, the slider 603 is driven to slide inside the installation bin 602 by the toggle rod 607, so that the slider 603 drives the limit block 604 to disengage from the limit groove 609 and store it in the installation bin 602. At this time, the damaged pallet 5 can be removed from the outer frame 1 for replacement. When replacing a new pallet 5, align the slot 608 on its bottom surface with the installation bin 602 and the support bar 601 and put it down. Then, the slider 603 is pushed back by the installation spring 605 to drive the limit block 604 to be inserted into the limit groove 609 for fixing.

[0041] (2) When stacking materials, the materials are stacked on the inner side of the four baffles 701, and the baffles 701 are activated to prevent the materials from slipping. When the trays are not in use, multiple trays are stacked directly. The support block 4 on the top tray will squeeze the baffle 701, causing it to slide downward inside the storage slot 705, while the squeezing block 702 slides upward inside the movable slot 706 and compresses the reset spring 703 to complete the storage. When the top tray is removed, the reset spring 703 pushes the baffle 701 to cooperate with the guide rod 704 to move up and reset.
