Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of forklifts, and more specifically relates to a forklift fork. Background Art
[0002] The forklift fork is one of the core components of a forklift, used for handling and stacking goods. It is usually made of high-strength steel, with high wear resistance and strength to cope with frequent heavy-duty operations. The design of the fork follows strict standards to ensure its safety and reliability during use. The length and width of the fork can be selected and adjusted according to different operation requirements to adapt to various types of pallets and goods. The smooth surface and precise size design at the bottom of the fork make the goods more stable and smooth during loading and unloading. The height adjustment function of the fork enables it to flexibly meet the requirements of stacking goods at different heights. However, during use, when the forklift is in transportation, there is no fixing device for the goods placed on the fork. If the forklift suddenly stops or for other reasons, the goods may slide due to inertia, vibration, or uneven ground, etc. The sliding of the goods will not only damage the goods but may also cause injury to the operator.
[0003] For the existing forklift forks, during use, the effect of resisting goods is poor. For a fork without a baffle, during transportation, the goods are likely to slide due to the movement, turning, or vibration of the forklift, resulting in damage to the goods. The sliding of the goods may hit the operator or other workers, causing safety accidents and threatening personal safety. Summary of the Utility Model

However, it does not exclude that those skilled in the art can implement the present invention with technical solutions that do not contain the above-mentioned structures, performances, effects or other features under specific circumstances.
[0030] In the drawings, the same reference numerals denote the same or similar elements, components or parts, so the repeated description of the same or similar components or parts may be omitted hereinafter. It should also be understood that although attributives such as first, second, third, etc. may be used herein to describe various components or parts, these components or parts should not be limited by these attributives. That is to say, these attributives are only used to distinguish one from another. For example, the first component may also be called the second component without departing from the essential technical solution of the present invention. In addition, the terms "and / or", "or / and" refer to all combinations including any one or more of the listed items.
[0031] To make the purpose, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to specific embodiments and the accompanying drawings.
[0032] Figure 1 It is a schematic diagram of the overall structure of the present invention. As Figure 1 shown, the forklift fork includes a bracket 1 and a fork body 2. One end of the bracket 1 is connected to the forklift, and the other end is connected to one end of the fork body 2. A baffle mechanism 3 for preventing the goods from slipping is provided at the other end of the fork body 2;
[0033] Figure 2 It is a schematic diagram of the structure of the fork mounting groove 301 of the present invention. Combining Figure 1 and Figure 2 , the baffle mechanism 3 includes a mounting groove 301, a baffle 302, a transmission device 303, a control motor 304 and a filling device 4. The mounting groove 301 is opened in the baffle mechanism 3. The baffle 302 is rotatably connected to the surface of the mounting groove 301. The control motor 304 is arranged on the outer side surface of the baffle mechanism 3. The baffle 302 is connected to the control motor 304 through the transmission device 303. The filling device 4 is arranged below the baffle 302. When the baffle 302 rotates in the vertical direction, the filling device 4 moves upward to fill the gap generated after the rotation of the baffle 302.
[0034] Figure 3 It is a schematic diagram of the mutual cooperation structure of the transmission device 303 and the baffle 302 of the present invention. As Figure 3As shown, the transmission device 303 includes a gear 3031 and a worm 3032. The center of the gear 3031 is fixedly connected to the rotating shaft of the baffle 302. One end of the worm 3032 is connected to the rotating shaft of the control motor 304, and the other end meshes with the gear 3031. During use, the worm 3032 is driven to rotate by the control motor 304, driving the gear 3031 to rotate. The gear 3031 drives the baffle 302 to rotate. When not in use, the baffle 302 is stored inside the installation groove 301. After being rotated out, it is perpendicular to the surface of the forklift fork body 2, serving as the baffle 302. Since it is controlled by the worm 3032 and the gear 3031, it has good self-locking performance. Only when the worm 3032 rotates can the baffle 302 be driven to rotate. When the baffle 302 is under pressure, it will not rotate, achieving a safety locking effect.
[0035] Figure 4 This is a schematic structural diagram of the cooperation between the baffle 302 and the extension plate 307 of the present utility model. As Figure 4 shown, an electric gear 305 is provided on the upper surface of the baffle 302. An extension plate 307 is provided inside the baffle 302. The extension plate 307 is slidably connected to the inner side surface of the baffle 302. A rack 306 is vertically provided on the extension plate 307. The rack 306 meshes with the electric gear 305. When the baffle 302 is in a vertical state, rotating the electric gear 305 can make the extension plate 307 move in the vertical direction, changing the overall height of the baffle 302 formed by the baffle 302 and the extension plate 307 to block higher items, achieving the effect of adding a baffle 302 structure for items on the forklift fork of the truck, and facilitating the adjustment of the working state, making it safer and more reliable during transportation.
[0036] Figure 5 This is a schematic structural diagram of the filling device 4 of the present utility model. Figure 6 This is a schematic structural diagram of the cooperation between the lifting plate 402 and the engaging block 403 of the present utility model. As Figure 5 and Figure 6 shown, the filling device 4 includes a limiting groove 401, a lifting plate 402, an engaging block 403, and a limiting post 404. The limiting groove 401 is opened on the inner side wall of the installation groove 301. A limiting post 404 is vertically and fixedly connected inside the limiting groove 401. The engaging block 403 is fixedly connected to the side surface of the lifting plate 402. An installation hole 405 is opened on the engaging block 403. The engaging block 403 is sleeved on the limiting post 404 through the installation hole 405 and is slidably connected to the limiting post 404. A compression spring 406 is sleeved outside the limiting post 404. The engaging block 403 is located above the compression spring 406. The compression spring 406 supports the bottom of the lifting plate 402 to actively lift the lifting plate 402 and finally be on the surface of the forklift fork body 2, used to fill the gap generated after the baffle 302 rotates. In Figure 6Among them, the number of the limit posts 404 is 4, which are evenly arranged on both side surfaces of the lifting plate 402. Correspondingly, the number of the engaging blocks 403 is also 4.
[0037] Preferably, the baffle 302 is L-shaped. When the baffle 302 rotates in the vertical direction, the bent part 308 of the baffle contacts the lower surface of the lifting plate 402 and hooks up the lifting plate 402 to lift it, cooperating with the compression spring 406 to lift the lifting plate 402.
[0038] Figure 7 This is a schematic diagram of the positions of the rubber soft pad 407 and the rubber hard pad 408 of the present utility model. As Figure 7 shown, combined with Figure 5 , the filling device 4 further includes a rubber soft pad 407 and a rubber hard pad 408. The rubber soft pad 407 is fixedly arranged on the inner wall of one end of the installation groove 301, located on the Figure 5 right side in , abuts against the baffle 302, and contacts the baffle 302 to ensure the tightness of the rotating part.
[0039] The rubber hard pad 408 is fixedly arranged on the inner wall of the other end of the installation groove 301, located on the Figure 5 left side in . When the lifting plate 402 moves in the vertical direction, the rubber hard pad 408 abuts against one end of the lifting plate 402. When the baffle 302 wants to reverse and retract, it will push open a part of the lifting plate 402. At the same time, the size of the installation hole 405 is slightly larger than the diameter of the limit post 404. In Figure 5 , the lifting plate 402 can make a certain displacement to the left. The displaced part will squeeze the rubber hard pad 408 and cause a certain displacement. The rubber hard pad 408 can fill the gap generated by the displacement, achieving the effect of cooperating with the baffle mechanism 3 to fill the gap and preventing the items on the surface of the forklift fork from falling into the interior during use.
[0040] During operation, the baffle 302 is stored in the installation groove 301 when not in use. When needed, the motor 304 is controlled to drive the worm 3032 to rotate. The worm 3032 drives the gear 3031 to rotate, driving the baffle 302 to rotate. When it rotates to a position perpendicular to the surface of the forklift fork, it functions as the baffle 302. The baffle 302 will not rotate under pressure, achieving a safety locking effect. The electric gear 305 rotates and drives the rack 306 engaged with it to move vertically, driving the extension plate 307 to move up and down within the baffle 302, changing the overall height of the baffle 302 formed by the baffle 302 and the extension plate 307 to block higher items. The lifting plate 402 is installed in the limit groove 401 through the engaging block 403 and can slide up and down. The limit post 404 is installed with a compression spring 406 to support the bottom of the lifting plate 402 for actively lifting the lifting plate 402. When the baffle 302 rotates out from the inside, the L-shaped bend will hook the lifting plate 402 to assist the compression spring 406 in lifting, and finally it is on the surface of the forklift fork body 2 to fill the space generated after the baffle 302 rotates and rises. A rubber soft pad 407 is installed at one end in the installation groove 301 to contact the baffle 302 to ensure airtightness at the rotating part, and a rubber hard pad 408 is installed at the other end to contact the lifting plate 402. Since the size of the installation hole 405 is slightly larger than that of the limit post 404, when the baffle 302 wants to reverse and retract, it will push the lifting plate 402 to one side by a certain amount. The lifting plate 402 can make a certain displacement, and the pushed part will squeeze the rubber hard pad 408 and generate a certain displacement. The rubber hard pad 408 can fill the gap generated by the displacement.
[0041] By providing a baffle mechanism on the forklift fork, the present utility model can effectively prevent goods from slipping or tipping during transportation. Especially when transporting higher or irregularly shaped items, the combination of the rotating baffle and the extension plate can form a baffle with adjustable height, enabling the height of the baffle to be adjusted according to the height of the goods, thereby providing better fixation and protection. Through the mechanical structure driven by controlling the motor and the gear, the rotating baffle can be easily stored and deployed, with simple operation, no need for manual adjustment, saving the time and energy of the operator. At the same time, it also provides a good self-locking function. This self-locking design also ensures that during transportation, the baffle always remains in the predetermined position, will not accidentally loosen or retract, and increases the safety of transportation.
