[0002] In the modern warehousing industry, efficient utilization of warehouse space is a key issue. With rising land costs, businesses need to store more goods within limited warehouse space. Traditional fixed-length forks offer limited flexibility when dealing with racks of varying sizes and storage layouts. Telescopic forks, on the other hand, effectively solve this problem.

[0003] Currently, one type of telescopic fork in the technology has poor practicality because of the design of its fork plates, which cannot be adjusted in angle. It takes up a lot of space when not in use, is inconvenient to place, and has poor practicality. In addition, the existing telescopic fork cannot adjust the angle of its fork plates according to actual needs, which has great limitations and poor practicality. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of existing technology, which has a large space-consuming and inconvenient placement due to the setting of the fork plate, the inability to adjust the angle of the fork plate, and the inability to adjust the angle of the fork plate according to actual needs, and thus has great limitations. Therefore, a telescopic fork is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a telescopic fork, including a main board, a connecting plate on the rear side of the main board, a first motor mounted on the end of the connecting plate facing the main board, the output end of the first motor being fixed to the main board, support blocks on both sides of the end of the main board away from the connecting plate, a driving structure for driving the two support blocks to move in opposite directions within the main board, a first opening on the outer wall of the support block, a rotating block rotatably connected within the first opening, a first fork plate fixed on the outer wall of the rotating block, a second fork plate slidably connected to the outer side of the first fork plate, a telescopic rod mounted on one end of the rotating block, and the output end of the telescopic rod being fixed to the second fork plate.

[0006] Preferably, the drive structure includes a second motor located on one side of the motherboard. The output end of the second motor passes through one side of the motherboard and is fixed with a bidirectional screw. Both ends of the outer wall of the bidirectional screw are threaded with moving blocks. Both ends of the two moving blocks are slidably connected with limit posts. One end of each of the two moving blocks is fixed with a connecting block. The ends of the two connecting blocks away from the moving blocks pass through the motherboard and are respectively fixed to two support blocks.

[0007] Preferably, the end of the bidirectional screw away from the second motor is rotatably connected to the main board, and both ends of the limiting post are fixed to the main board.

[0008] Preferably, a bracket is fixed at one end of the motherboard, the second motor is mounted on the end of the bracket facing the motherboard, and movable slots matching the connecting block are opened on both sides of one end of the motherboard.

[0009] Preferably, one end of the main board is rotatably connected to a collar on the outside of the first motor, and a slider is fixed to the end of the collar facing the connecting plate. The end of the connecting plate facing the collar has a groove that matches the slider.

[0010] Preferably, mounting plates are fixed at both ends of the outer wall of the connecting plate, and mounting holes are provided in both mounting plates.

[0011] Preferably, a third motor is installed inside the support block, and the output end of the third motor is fixed to the rotating block.

[0014] In this invention, the operation of the first motor drives the entire main board to rotate, thereby adjusting the angles of the two first forks and two second forks. The use of rings, sliders, and grooves provides stable support for the first motor, preventing damage from the first motor supporting the entire main board alone, thus enhancing stability. Furthermore, the operation of the third motor drives the rotating block to rotate, causing the first and second forks to rotate around the rotating block as a center point. When not in use, the first and second forks can rotate to be parallel to the main board, significantly reducing its footprint and enhancing practicality. Attached Figure Description

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, as Figure 1-4 As shown, this utility model provides a telescopic fork, including a main board 1, a connecting plate 2 on the rear side of the main board 1, a first motor 6 installed on the end of the connecting plate 2 facing the main board 1, the output end of the first motor 6 fixed to the main board 1, support blocks 9 on both sides of the end of the main board 1 away from the connecting plate 2, a drive structure 10 for driving the two support blocks 9 to move in opposite directions, a first opening 13 is opened on the outer wall of the support block 9, a rotating block 15 is rotatably connected in the first opening 13, a first fork plate 16 is fixed on the outer wall of the rotating block 15, a second fork plate 17 is slidably connected to the outer side of the first fork plate 16, a telescopic rod 20 is installed on one end of the rotating block 15, and the output end of the telescopic rod 20 is fixed to the second fork plate 17.

[0023] The overall effect of Embodiment 1 is that, through the operation of the drive structure 10, the two support blocks 9 can be moved in opposite directions, thereby enabling the two first fork plates 16 to adjust the distance between them according to the cargo, thus enhancing practicality. Through the operation of the first motor 6, the main board 1 can be rotated as a whole, thereby adjusting the angles of the two first fork plates 16 and the two second fork plates 17. In addition, through the operation of the third motor 14, the rotating block 15 can be rotated, thereby enabling the first fork plates 16 and the second fork plates 17 to rotate around the rotating block 15 as the center point. When the device is not in use, the first fork plates 16 and the second fork plates 17 can be rotated to be parallel to the main board 1, greatly reducing its footprint and enhancing practicality. Through the operation of the telescopic rod 20, the second fork plate 17 can slide on the first fork plate 16, and the second fork plate 17 can move a distance away from the first fork plate 16, achieving a telescopic effect.

[0024] Example 2, as Figure 1-4 As shown, the drive structure 10 includes a second motor 1001 located on one side of the main board 1. The output end of the second motor 1001 passes through one side of the main board 1 and is fixed with a bidirectional screw 1002. Both ends of the outer wall of the bidirectional screw 1002 are threadedly connected to moving blocks 1003. Both ends of the two moving blocks 1003 are slidably connected to limit posts 1004. One end of each of the two moving blocks 1003 is fixed with a connecting block 1005. The ends of the two connecting blocks 1005 away from the moving blocks 1003 pass through the main board 1 and are respectively fixed to two support blocks 9. The end of the bidirectional screw 1002 away from the second motor 1001 is rotatably connected to the main board 1. Both ends of the limit posts 1004 are fixed to the main board 1. One end of the main board 1 is fixed with a bracket 12. The second motor 1001 is mounted on the bracket 12 facing the main board 1. At one end of plate 1, both sides of the main plate 1 are provided with moving grooves 11 that match the connecting block 1005. One end of the main plate 1 is rotatably connected to the outer side of the first motor 6. A slider 4 is fixed at the end of the collar 3 facing the connecting plate 2. A sliding groove 5 that matches the slider 4 is provided at the end of the connecting plate 2 facing the collar 3. Mounting plates 7 are fixed at both ends of the outer wall of the connecting plate 2. Mounting holes 8 are provided in both mounting plates 7. A third motor 14 is installed in the support block 9. The output end of the third motor 14 is fixed to the rotating block 15. A second opening 21 is provided at the bottom end of the second fork plate 17. The telescopic rod 20 is located in the second opening 21. Limiting blocks 18 are fixed at both ends of the inner wall of the second fork plate 17. Limiting grooves 19 that match the limiting blocks 18 are provided at both ends of the outer wall of the first fork plate 16.

[0025] The overall effect of Embodiment 2 is that, through the setting of the collar 3, slider 4 and slide groove 5, the first motor 6 can be stably supported, avoiding the problem of damage caused by the first motor 6 supporting the main board 1 alone, thus improving stability. The operation of the second motor 1001 can drive the bidirectional screw 1002 to rotate, causing the two moving blocks 1003 to move towards or away from each other under the limitation of the limiting post 1004, thereby driving the two supporting blocks 9 connected by the two connecting blocks 1005 to move towards or away from each other. Through the setting of the mounting plate 7 and mounting hole 8, the connecting plate 2 can be connected to the driving mechanism of trucks, etc. Through the setting of the limiting block 18 and limiting groove 19, the second fork plate 17 can be limited to prevent it from moving out of the first fork plate 16.

[0026] Working principle: When in use, the device connects the connecting plate 2 to the drive mechanism of a truck or similar vehicle via the mounting plate 7 and mounting holes 8. The second motor 1001 drives the bidirectional screw 1002 to rotate, causing the two moving blocks 1003 to move towards or away from each other under the limit of the limiting post 1004. This, in turn, causes the two supporting blocks 9 connected to the two connecting blocks 1005 to move towards or away from each other, allowing the two first fork plates 16 to adjust their spacing according to the cargo. The telescopic rod 20 causes the second fork plate 17 to slide on the first fork plate 16, achieving a telescopic effect by moving one end of the second fork plate 17 away from the first fork plate 16. The operation of the first motor 6 drives the main board 1 to rotate, thereby adjusting the angles of the two first forks 16 and the two second forks 17. The first motor 6 is stably supported by the collar 3, slider 4 and slide groove 5, preventing damage caused by the first motor 6 supporting the main board 1 alone, thus enhancing stability. In addition, the operation of the third motor 14 drives the rotating block 15 to rotate, thereby causing the first forks 16 and the second forks 17 to rotate around the rotating block 15 as the center point. When the device is not in use, the first forks 16 and the second forks 17 can be rotated to be parallel to the main board 1, greatly reducing its footprint and enhancing its practicality.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
