[0001] This utility model relates to the field of forklift fork technology, specifically a forklift fork with a buffer function. Background Technology
[0002] Forklift forks are the core load-bearing components of a forklift used to directly pick up, carry, and transport goods. They are the key actuators that enable the material handling function of a forklift. Their core functions include directly contacting and carrying goods, lifting goods by inserting the fork tips into the pallet, maintaining the stability of goods during forklift travel, lifting, or turning to prevent slippage and deviation, and can also be used as a basic component in conjunction with attachments such as swivels and side shifters to adapt to different types of goods handling needs.
[0003] To reduce swaying, existing forklift forks need to be equipped with multiple damping spring shock absorbers. The disassembly and assembly of multiple damping spring shock absorbers requires multiple bolts and nuts, making the process cumbersome and time-consuming. In addition, when there are impurities on the fork surface, the moving forks can damage the goods through these impurities. Utility Model Content

The lower ends of the two sets of connecting rods 11 are welded to the upper part of the sleeve plate 9, ensuring that the sleeve plate 9 can move the mounting seat 12 through the two sets of connecting rods 11. The height of the multiple sets of damping spring shock absorbers 13 can be adjusted to the connection position simultaneously. With the quick locking and unlocking design of the mounting rod 19 and the threaded tube 17, there is no need to disassemble the bolts and nuts one by one, simplifying the disassembly and assembly process and saving manpower and time costs. At the same time, the vertical rod 5 ensures the stability of the adjustment process, further improving the practicality of the fork structure. Please see Figure 1 , Figure 2 and Figure 6Both sets of connecting plates 3 have mounting cavities 20 inside, and mounting shafts 21 are mounted inside each mounting cavity 20 via bearings. The two sets of mounting shafts 21 are fixedly connected to the two sets of forks 4 via connectors, ensuring that the two sets of mounting shafts 21 can drive the two sets of forks 4 to rotate. Self-locking motors 22 are fixedly mounted on the end faces of both sets of connecting plates 3, and main gears 23 are fixedly sleeved on the output ends of both sets of self-locking motors 22. Driven gears 24 and limiting hole plates 25 are fixedly sleeved on the side walls of both sets of mounting shafts 21. Multiple sets of ball sockets 26 are provided on the side walls of both sets of limiting hole plates 25, and ball bearings 27 are provided inside the multiple sets of ball sockets 26 on the same side. An electrical control box is mounted on the rear end face of the connecting frame 1, and the electrical control box contains... Equipped with a control panel and a battery, the control panel is electrically connected to the battery and two sets of self-locking motors 22 via wires. The control circuit of the control panel can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail. Relying on the self-locking motors 22 on the connecting plate 3, the main gear 23 and the driven gear 24 can drive the forks 4 to rotate and use centrifugal force to throw off surface impurities, eliminating the need for manual cleaning. The cooperation between the ball bearings 27 and the limit hole plate 25 ensures the stability of the forks 4 during rotation, and can quickly remove impurities that may crush the goods, providing a guarantee for the safe picking of goods and avoiding the risk of goods being damaged by impurities. Please see Figure 1 , Figure 3 and Figure 5 The lower part of the lifting plate 2 is provided with a groove 15, and positioning tubes 16 are welded on both sides of the groove 15. An installation rod 19 is provided inside the groove 15, and screws 18 are welded to both ends of the installation rod 19. Threaded tubes 17 are sleeved on the side walls of the two sets of screws 18. The installation rod 19 can be inserted into the interior of multiple sets of concave plates 14 to realize the connection between the lifting plate 2 and multiple sets of damping spring shock absorbers 13. Please see Figure 3 The two sets of screws 18 are threaded together with the two sets of threaded tubes 17. The use position of the two sets of threaded tubes 17 can be adjusted by rotating the two sets of threaded tubes 17 clockwise and counterclockwise. Please see Figure 6 The two sets of main gears 23 mesh with the two sets of driven gears 24 to ensure that the two sets of main gears 23 can drive the two sets of driven gears 24 to rotate. Please see Figure 6 The diameter of the opening of the multiple sets of ball sockets 26 on the same side is less than the diameter of the multiple sets of balls 27 on the same side, so as to prevent the multiple sets of balls 27 on the same side from moving out of the interior of the multiple sets of ball sockets 26 on the same side. Please see Figure 1 Mounting plates are installed on both sides of the connecting frame 1, and the two sets of mounting plates can be connected to the mast of the forklift by bolts.
[0018] In this invention, the working steps of the device are as follows: When multiple sets of damping spring shock absorbers 13 need to be installed, the worker manually rotates the handwheel, which drives the lead lever 7 to rotate. The rotating lead lever 7 pushes the lead screw sleeve 8 up or down. When the lead screw sleeve 8 moves the multiple sets of damping spring shock absorbers 13 to the connection position through the connecting plate 9 and the two sets of connecting rods 11, the worker then moves the mounting rod 19 into the groove 15. When the mounting rod 19 is inserted into the multiple sets of concave plates 14, the two sets of screws 18 and the two sets of threaded tubes 17 engage with each other. Workers manually rotate the two sets of threaded tubes 17 clockwise and counterclockwise. When the two sets of threaded tubes 17 are inserted into the two sets of positioning tubes 16 respectively, the connection is completed. When multiple sets of damping spring shock absorbers 13 need to be disassembled, the two sets of threaded tubes 17 are rotated in the opposite direction. When the two sets of threaded tubes 17 are moved out of the two sets of positioning tubes 16 respectively, the mounting rod 19 can be removed, completing the disassembly. The vertical rod 5 can ensure the stability of the sleeve plate 9 moving up and down. The lifting plate 2 and the mounting box 6 facilitate the disassembly and assembly of the damping spring shock absorbers. The nylon spring shock absorber structure improves the practicality of the forklift forks with cushioning function. Simultaneously, when impurities are present on the surfaces of the two sets of forks 4, the control panel activates a self-locking motor 22. The output of this self-locking motor 22 drives a set of main gears 23 on the same side to rotate. Since the two sets of main gears 23 mesh with the two sets of driven gears 24, the rotating main gear 23 pushes the set of driven gears 24 on the same side to rotate. The set of driven gears 24 on the same side can rotate the set of forks 4 on the same side via a set of mounting shafts 21 on the same side. Using centrifugal force, the set of forks 4 on the same side can dislodge impurities. During this process, multiple sets of ball bearings 27 on the same side roll along the inner wall of a set of mounting cavities 20 on the same side. A set of limiting plates 25 on the same side assists in stabilizing the rotation of the set of mounting shafts 21 on the same side. The other set of forks 4 operates similarly. Through the connecting plate 3, impurities on the surface of the fork structure can be cleaned, providing a guarantee for the safe lifting of goods by the forklift forks with cushioning function.
