Description

Technical Field

[0001] This utility model relates to the field of forklift technology, and more specifically, to a forklift. Background Technology

[0002] The forks are the key components of a forklift. They are like robotic arms mounted on the forklift, making the forklift a multi-purpose and highly efficient material handling tool. It can perform operations such as forking, clamping, pushing, pulling, lateral movement, and rotating on almost any imaginable object to be handled.

[0003] Most existing forks are one-piece structures. Some are divided into two parts for easier storage, achieving folding and shrinking to reduce space occupation. However, such folding forks can only reduce space occupation, but cannot freely adjust the overall length of the forks according to actual working needs, which has certain limitations. Therefore, we provide a different type of fork. Summary of the Invention

[0004] The purpose of this utility model is to provide a forklift to solve the problems mentioned in the background art above:

[0005] Most existing forks are one-piece structures. Some forks are split into two for easier storage, achieving folding and shrinking to reduce space usage. However, such folding forks can only reduce space usage and cannot freely adjust the overall length of the forks according to actual working needs, which has certain limitations.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fork includes a first fork body and a second fork body. The first fork body has a first groove inside, and there are two first grooves symmetrically distributed. A sliding plate is slidably connected inside the first groove. The second fork body is fixedly connected to the sliding plate. A rotating shaft is rotatably connected inside the first fork body. A locking block is sleeved on the outside of the rotating shaft. The locking block is fixedly connected to the rotating shaft. The sliding plate has a second groove inside, and a locking groove is provided between two adjacent second grooves. The locking groove communicates with the second groove. Both the locking groove and the second groove are used in conjunction with the locking block.

[0008] Preferably, both the first groove and the slide plate have a cross-shaped cross-section.

[0009] Preferably, the outer wall of the slide plate is fitted with the inner wall of the first groove.

[0010] Preferably, the second groove is an elongated strip structure, and the slot is a circular structure.

[0011] Preferably, a groove is provided on one side of the first fork body, and a knob is provided inside the groove. The knob is fixedly connected to a rotating shaft, and a rod is slidably connected inside the knob. There are two rods, and a spring is fixedly connected between the two rods. A slot is provided inside the first fork body. There are four slots in total, and the four slots are symmetrically distributed. The slots communicate with the groove, and the slots are used in conjunction with the rods.

[0012] Preferably, a third sliding groove is provided inside the knob on the side away from the rotating shaft, and a pressure rod is slidably connected inside the third sliding groove, and the pressure rod is fixedly connected to the insertion rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Pressing the lever moves the insert rod until it separates from the slot. Rotating the knob rotates the locking block to a horizontal position, at which point the locking block disengages from the slot. The operator can then directly adjust the position of the second fork body. After adjustment, the knob can be rotated 90 degrees or in the opposite direction to rotate the locking block to a vertical position. Releasing the lever causes the insert rod to automatically engage with the corresponding slot due to the spring force, thus limiting the locking block. Finally, the locking block and slot lock the slide plate in the first slide groove, achieving the purpose of adjusting the overall length to adapt to different usage scenarios.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 6 A fork includes a first fork body 1 and a second fork body 2. The first fork body 1 has two first sliding grooves 3 symmetrically distributed inside. A sliding plate 4 is slidably connected inside each first sliding groove 3. The length between the first fork body 1 and the second fork body 2 can be freely adjusted by the action of the first sliding grooves 3 and the sliding plate 4, while also reducing the space occupied when retracted. The second fork body 2 is fixedly connected to the sliding plate 4. A rotating shaft 5 is rotatably connected inside the first fork body 1, and a sleeve is fitted around the outside of the rotating shaft 5. There is a locking block 6, which is fixedly connected to the rotating shaft 5. The interior of the slide plate 4 is provided with a second slide groove 7. A locking groove 8 is provided between two adjacent second slide grooves 7. The locking groove 8 is connected to the second slide groove 7. Both the locking groove 8 and the second slide groove 7 are used in conjunction with the locking block 6. Multiple sets of locking grooves 8 and second slide grooves 7 are arranged at equal intervals. The locking block 6 is a long strip structure and can be in two states: horizontal and vertical. When the locking block 6 is in the horizontal state, the slide plate 4 can move freely. When the locking block 6 is in the vertical state, the locking block 6 engages with the locking groove 8, thereby locking the slide plate 4 and the first slide groove 3.

[0024] Furthermore, both the first slide groove 3 and the slide plate 4 have cross-shaped cross sections. The cross-shaped cross section ensures that the slide plate 4 can only move back and forth within the first slide groove 3 without detaching.

[0025] Furthermore, the outer wall of the slide plate 4 is fitted to the inner wall of the first slide groove 3, and the slide plate 4 and the first slide groove 3 are tightly fitted, which can ensure the stability of the slide plate 4 and prevent the slide plate 4 from shaking with the first slide groove 3.

[0026] Furthermore, the second slide 7 is a long strip structure, and the slot 8 is a circular structure. The circular structure allows the block 6 to rotate within the slot 8 without causing it to jam.

[0027] Furthermore, a groove 9 is provided on one side of the first fork body 1, and a knob 10 is provided inside the groove 9. The knob 10 is fixedly connected to the rotating shaft 5. A plug rod 11 is slidably connected inside the knob 10. There are two plug rods 11, and a spring 12 is fixedly connected between the two plug rods 11. A slot 13 is provided inside the first fork body 1. There are four slots 13 in total. The four slots 13 are symmetrically distributed and communicate with the groove 9. The slots 13 cooperate with the plug rods 11 to lock the position of the locking block 6 through the plug rods 11 and the slots 13. After the position of the locking block 6 is locked, the sliding plate 4 and the first sliding groove 3 can be positioned through the locking block 6 and the locking groove 8.

[0028] Furthermore, a third groove 14 is provided inside the knob 10 on the side away from the rotating shaft 5. A pressure rod 15 is slidably connected inside the third groove 14. The pressure rod 15 is fixedly connected to the insertion rod 11. By pressing the pressure rod 15 towards the center of the knob 10, the pressure rod 15 can drive the insertion rod 11 to separate from the slot 13. Then, by rotating the knob 10 through the pressure rod 15, the position of the locking block 6 can be adjusted.

[0029] The steps for using this utility model are as follows: When using this fork, if it is necessary to adjust the overall length, press the pressure rod 15 on one side towards the center of the knob 10. The pressure rod 15 will drive the insertion rod 11 to move, and the insertion rod 11 will compress the spring 12 until the insertion rod 11 separates from the slot 13. Then, rotate the knob 10 by the pressure rod 15, so that the knob 10 rotates 90 degrees. At this time, the knob 10 will drive the locking block 6 to rotate to a horizontal state through the rotating shaft 5. At this time, the locking block 6 will disengage from the slot 8, and the operator can directly adjust the position of the second fork body 2. After the adjustment is completed, the knob 10 can be rotated 90 degrees again, or the knob 10 can be rotated in the opposite direction to make the locking block 6 rotate to a vertical state. After releasing the pressure rod 15, due to the elasticity of the spring 12, the insertion rod 11 will automatically engage with the corresponding slot 13, thereby limiting the locking block 6. Finally, the locking block 6 and the slot 8 lock the slide plate 4 in the first slide groove 3, thereby achieving the purpose of adjusting the overall length and adapting to different usage scenarios.
