Description

Technical Field

[0001] This utility model relates to the technical field of automotive component protection, and in particular to a safety protective cover that can be quickly installed and disassembled. Background Technology

[0002] In the entire process of automotive parts production and processing, transfer, logistics transportation, and storage are key links to ensure production continuity and product quality. To achieve large-scale and standardized circulation of automotive parts, pallets are widely used as the core load-bearing equipment. Workers typically place various automotive parts neatly on pallets, and then use forklifts, AGVs, and other equipment to complete the transfer, loading, unloading, and warehousing stacking of the parts. This method significantly improves the efficiency of automotive parts circulation and reduces manual handling costs.

[0003] However, existing pallets used for the transfer of automotive parts generally suffer from a lack of protective structures or inadequate protective effects. Currently, most pallets only have basic load-bearing functions and are not equipped with dedicated protective devices. Although temporary protective methods such as wrapping with stretch film or binding with straps are used in some scenarios, these methods have obvious drawbacks: First, the protective stability is poor. During the start-stop and turning of forklifts or under the vibration of warehouse stacking, automotive parts on the pallet are prone to displacement, posing a risk of collision. This is especially true for fragile parts such as precision components (e.g., vehicle sensors, headlights) and irregularly shaped sheet metal parts (e.g., doors, fenders), which are easily damaged, causing surface scratches, structural deformation, and other damage. Second, the protective reliability is insufficient. Temporary protective methods cannot provide comprehensive restraint for the parts. During the bumpy process of transfer or loading and unloading, the parts are at risk of falling off, which can not only lead to product scrap but also pose a safety hazard in the field.

[0004] The aforementioned problem of insufficient pallet protection not only seriously affects the product quality of automotive parts, but also greatly reduces the reliability and safety of pallets in the circulation of automotive parts, failing to meet the high standards of protection required by the automotive industry during the circulation of parts.

[0068] The working principle of this utility model is as follows:

[0069] This utility model's quick-installation and disassembly safety cover achieves safety protection for the transportation and storage of automotive parts through a collaborative working mode of "base frame positioning - size adjustment - enclosure protection - locking and fixing".

[0070] The specific workflow is as follows:

[0071] First, adjust the size of the adjustable base frame 1 according to the specifications of the tray 5. Push the adjustable corner bracket 7 to make the telescopic plate 8 slide in the telescopic groove of the basic corner bracket 6. Adjust until the adjustable base frame 1 can be accurately placed on the edge of the tray 5. At this time, the inner baffle 2 and the top of the tray 5 are in close contact to complete the initial positioning. Tighten the locking bolt 9 with the knob to fix the size of the adjustable base frame 1.

[0072] Secondly, while the adjustable base frame 1 is being adjusted, the size of the adjustable enclosure 3 is also being changed to adapt. The telescopic shaft 12 of the auxiliary enclosure 11 slides synchronously within the telescopic tube 13 of the main enclosure 10. Finally, after the adjustable base frame 1 is adjusted, the adjustable enclosure 3 completes the adjustment process simultaneously.

[0073] Subsequently, the locking assembly is fixed by rotating the locking handle 17 to drive the adjusting threaded rod 15 to rotate. First, the rotating rod 16 is rotated to make the extrusion plate 18 rotate to the lower side of the tray 5. Then, the threaded engagement drives the rotating rod 16 to move upward along the through hole of the support plate 14 and the reinforcing hole of the reinforcing block 19, so that the extrusion plate 18 is tightly attached to the bottom edge of the tray 5. At this time, the locking handle 17 is tightly attached to the support plate 14, and the anti-slip washer 21 enhances the locking stability, forming an upper and lower clamping structure to firmly lock the protective cover on the tray 5.

[0074] After the transfer or storage is completed, rotate the locking handle 17 in the opposite direction to disengage the extrusion plate 18 from the bottom of the tray 5. At this time, the locking handle 17 does not need to be rotated continuously. As long as the extrusion plate 18 is no longer in close contact with the tray 5, the extrusion plate 18 can be rotated out. Then, the adjustable base frame 1 and the adjustable guardrail 3 can be removed from the tray 5.

[0075] The entire process requires no additional tools, enabling rapid installation and disassembly. At the same time, the adjustable structure adapts to different specifications of trays and components, and the all-round protective structure effectively avoids the risk of bumps and falls, ensuring the safety and quality of automotive parts transfer.

[0076] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
