Technical Field
[0001] This utility model relates to the field of forklifts, specifically to a forklift fork. Background Technology
[0002] Forklifts are industrial material handling vehicles, various types of wheeled vehicles used for loading, unloading, stacking, and short-distance transport of palletized goods. They are widely used in stations, ports, airports, factories, warehouses, and other locations. With societal development, the operating environment for forklifts has become increasingly complex, leading to higher demands on forklift design and manufacturing to meet the diverse functional requirements.
[0003] According to Chinese Patent No. CN220351642U, a forklift fork is disclosed. This utility model solves the problem that the width distance between the forks cannot be adjusted in the prior art, and that when encountering large or small goods, or when there is no pallet, the goods cannot be stably placed on the forks for transportation. It is simple and convenient to operate and has strong practicality.
[0004] Regarding the aforementioned patent content, a fork plate is provided so that it can be inserted into the fork holes of the pallet to transport goods. However, after the fork plate is inserted into the fork holes of the pallet, it is difficult to limit the pallet, which may cause the pallet to move, thereby reducing the stability of the pallet and reducing the effectiveness of the forks.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0037] The embodiments of this utility model will be described below based on its overall structure.
[0038] Example 1:
[0039] A type of forklift fork, such as Figures 1-7 As shown, the device includes a frame 1 and two fork plates 2. A blocking assembly 7 is provided on each fork plate 2. A drive motor 4 is mounted on the outer surface of the frame 1. The output end of the drive motor 4 is connected to a bidirectional lead screw 5, and two movable seats 3 are fitted onto the outer wall of the bidirectional lead screw 5. When it is necessary to adjust the distance between the two fork plates 2, the drive motor 4 can be started. The operation of the drive motor 4 drives the bidirectional lead screw 5 to rotate, thereby moving the movable seats 3. Two guide rods 6 are also installed inside the frame 1, passing through the movable seats 3. The guide rods 6 guide the movable seats 3 to improve their stability during movement. The movable seats 3 are threadedly connected to the bidirectional lead screw 5. One end of the bidirectional lead screw 5 is connected to the inner wall of the frame 1 via a bearing. When the bidirectional lead screw 5 rotates, it drives the two movable seats 3 to move simultaneously, thereby adjusting the position of the movable seats 3. A fork plate 2 is mounted on one side of the movable seat 3. The movement of the movable seat 3 drives the fork plate 2 to move, thereby adjusting the distance between the two fork plates 2.
[0040] See Figures 1-6The blocking component 7 includes a cavity 701 inside the fork plate 2 and a through groove 702 on the top of the fork plate 2. A groove 710 is provided at the bottom of the cavity 701, and a second motor 713 is installed on one side inside the groove 710. The output end of the second motor 713 is connected to a second threaded rod 712. A second threaded seat 711 is sleeved on the outer wall of the second threaded rod 712, and an adjusting seat 708 is installed on the top of the second threaded seat 711. A first motor 709 is installed on the top of the adjusting seat 708, and a first threaded rod 707 is connected to the output end of the first motor 709. A first threaded seat 705 is sleeved on the outer wall of the first threaded rod 707, and a baffle 703 is installed on the top of the first threaded seat 705. A threaded hole 704 is provided inside the baffle 703. When the fork plate 2 is inserted into the fork hole of the pallet, and one end of the fork plate 2 is removed from the fork hole, the operator can start the first motor 709. The operation of the first motor 709 can drive the first threaded rod 707 to rotate.
[0041] Specifically, the top end of the first threaded rod 707 is located inside the threaded hole 704, and the length of the first threaded rod 707 is greater than the depth of the threaded hole 704. When the first threaded rod 707 rotates, the baffle 703 can be moved, thereby adjusting the height of the baffle 703. The through groove 702 is connected to the cavity 701, and the top of the baffle 703 passes through the through groove 702, allowing the baffle 703 to move so as to adjust the position of the baffle 703. The adjusting seat 708 is slidably connected to the cavity 701, and the outer wall of the second threaded seat 711 fits against the inner wall of the groove 710 so that the adjusting seat 708 can move inside the cavity 701, thereby facilitating the adjustment of the position of the adjusting seat 708.
[0042] Example 2:
[0043] Based on the above embodiment 1, in order to prevent the first threaded seat 705 from rotating, the following structure will be provided to guide it.
[0044] See Figure 3 , Figure 5 , Figure 6 and Figure 7 A limiting rod 706 is installed on one side of the top of the adjusting seat 708, and a limiting block is connected to the top of the limiting rod 706. The limiting rod 706 passes through the first threaded seat 705. The limiting rod 706 can guide the first threaded seat 705 to improve the stability of the first threaded seat 705 and the baffle 703 when they move, and prevent the first threaded seat 705 and the baffle 703 from rotating.
[0045] The working principle of this utility model is as follows: First, when the fork plate 2 is inserted into the fork hole of the pallet and one end of the fork plate 2 is moved out of the fork hole, the operator can start the first motor 709. The operation of the first motor 709 can drive the first threaded rod 707 to rotate, thereby causing the first threaded seat 705 to move upward and drive the baffle 703 to move upward, so that the baffle 703 moves out of the cavity 701 and contacts the pallet, so as to block and limit the pallet and prevent the pallet from moving on the fork plate 2. If the baffle 703 that has moved out of the cavity 701 is a certain distance away from the pallet, the second motor 713 can be started. The operation of the second motor 713 can drive the second threaded rod 712 to rotate, thereby driving the second threaded seat 711 to move, and driving the adjusting seat 708 to move, and then driving the first threaded seat 705 and the baffle 703 to move, so as to adjust the position of the baffle 703, so that the baffle 703 can contact the pallet and play a limiting role.
[0046] When it is necessary to adjust the distance between the two fork plates 2, the drive motor 4 can be started. The operation of the drive motor 4 can drive the bidirectional lead screw 5 to rotate, thereby driving the two movable seats 3 to move. The movement of the movable seats 3 can drive the fork plates 2 to move, so as to adjust the distance between the two fork plates 2.
