[0002] In the field of logistics automation, the connection method of AGV forks has an important impact on the efficiency of cargo handling. The traditional connection method is usually to directly install the forks on the lifting frame using bolts.

[0003] This connection method has obvious disadvantages during the installation process. First, multiple bolts need to be aligned with the corresponding mounting holes one by one. This process requires a high degree of precision. A slight deviation may lead to installation failure and take a lot of time to adjust. Moreover, each bolt needs to be tightened with a tool. For a large number of bolts, the installation process is extremely cumbersome. At the same time, in order to ensure the firmness of the connection, it is often necessary to apply a large torque to the bolts, which further increases the difficulty and time cost of installation.

[0004] There are also many problems when disassembling. Bolts may rust or get stuck after long-term use, making disassembly extremely difficult. Specific tools are required for loosening, and it may take a lot of effort to unscrew the bolts. For some bolts that are difficult to remove, special methods such as heating and cutting may be required, which undoubtedly greatly increases the complexity and danger of disassembly.

[0029] The present invention provides a technical solution: a fastening connector for an AGV forklift fork, mainly including a rectangular plate 1, an L-shaped plate 2, a support block 3, a lifting and fastening mechanism 5, and a quick-connection mechanism 8. One side wall of the rectangular plate 1 is fixedly connected to the L-shaped plate 2, and the other side wall is fixedly connected to the support block 3.

[0030] The bottom of the L-shaped plate 2 is provided with a U-shaped groove 4, and the lifting and fastening mechanism 5 is installed in the U-shaped groove 4. The top surface of the support block 3 is fixedly connected with a fixed column 6, the top surface of the fixed column 6 is fixedly connected with a conical head 7, and the quick-connection mechanism 8 is installed on the conical head 7.

[0031] The lifting and fastening mechanism 5 is mainly composed of a lifting block 501, a pressing block 505, a rectangular block 506, a guide rod 508, a first spring 509, an adjusting bolt 510, etc.

[0032] The lifting block 501 is slidably connected to the inner wall of the U-shaped groove 4. A first rectangular hole 502 is formed in the side wall of the lifting block 501, a second rectangular hole 503 communicating with the first rectangular hole 502 is formed in the bottom, and a third rectangular hole 504 communicating with the first rectangular hole 502 is formed in the top surface.

[0033] The pressing block 505 is slidably connected to the inner wall of the first rectangular hole 502. A rectangular block 506 is fixedly connected to the bottom of the second rectangular hole 503, and a first wedge-shaped groove 507 is formed in the top surface inside the third rectangular hole 504.

[0034] The guide rod 508 is fixedly connected to the inner wall of the second rectangular hole 503 and slidably penetrates through the side wall of the rectangular block 506. The first spring 509 is sleeved on the outer wall of the guide rod 508 and abuts against the rectangular block 506.

[0035] The adjusting bolt 510 is threadedly penetrated through the top surface of the lifting block 501 and vertically upwardly rotates through the top surface of the L-shaped plate 2. By rotating the adjusting bolt 510, the height of the lifting block 501 can be adjusted.

[0036] In addition, the lifting and fastening mechanism 5 further includes a first mating driving rod 511, the top of which is fixedly connected to the bottom of the U-shaped groove 4, and a wedge-shaped head slidably mating with the wedge-shaped surface of the first wedge-shaped groove 507 is provided at the bottom end. When the lifting block 501 descends, the wedge-shaped head of the first mating driving rod 511 presses the first wedge-shaped groove 507, causing the pressing block 505 to move towards the forklift, thereby realizing the fastening of the forklift.

[0037] The quick-connection mechanism 8 is mainly composed of an insertion block 801, a jack 802, a housing 803, a T-shaped block 804, a second spring 805, a connecting rod 806, a movable block 807, a strip-shaped plate 809, a second mating driving rod 810, etc.

[0038] The side wall of the insertion block 801 is slidably connected to the side wall of the rectangular plate 1, and a jack 802 slidably connected to the outer wall of the tapered head 7 is formed in the top surface. The side wall of the insertion block 801 is fixedly connected to the housing 803.

[0039] The T-shaped block 804 is slidably penetrated through the side wall of the insertion block 801 inside the housing 803. An inclined surface slidably mating with the tapered surface of the tapered head 7 is formed at the bottom of the T-shaped block 804 at one end inside the jack 802, and the top surface of the T-shaped block 804 and the bottom surface of the tapered head 7 are in a blocking fit. The second spring 805 is sleeved on the outer wall of the connecting rod 806, and the T-shaped end of the T-shaped block 804 inside the housing 803 abuts against the second spring 805.

[0040] The connecting rod 806 is slidably penetrated through the side wall of the housing 803 and fixedly connected to the T-shaped block 804. One end of the connecting rod 806 outside the housing 803 is fixedly connected to the movable block 807, and a second wedge-shaped groove 808 is formed in the bottom of the movable block 807.

[0041] The strip plate 809 is fixedly connected to the side wall of the plug block 801, and the second mating drive rod 810 is slidably inserted through the top surface of the strip plate 809.

[0042] Working principle:

[0043] The L-shaped plate 2 and the rectangular plate 1 are inserted between the hanging plates of the AGV lifting frame at intervals. Rotate the adjusting bolt 510. As the adjusting bolt 510 rotates, the lifting block 501 moves upward in the U-shaped groove 4, and the first mating drive rod 511 remains relatively stationary. At this time, the wedge-shaped head at the bottom end of the first mating drive rod 511 contacts and squeezes the wedge-shaped surface of the first wedge-shaped groove 507 on the lifting block 501. The pressing block 505 slides along the first rectangular hole 502 towards the hanging plate of the AGV lifting frame. The rectangular block 506 at the bottom of the pressing block 505 moves smoothly under the restriction of the guide rod 508, and at the same time compresses the first spring 509. As the pressing block 505 approaches the hanging plate of the AGV lifting frame, the quick connection installation of the fastening connector is finally realized.

[0044] When installing the forklift 9, the AGV moves to the position of the forklift 9, and the conical head 7 is located directly below the jack 802. The AGV lifts the lifting frame, inserts the conical head 7 from below the jack 802, and aligns the jack 802 on the plug block 801 with the conical head 7 on the support block 3 and slidably connects them. During the cooperation process between the jack 802 and the conical head 7, the conical surface of the conical head 7 contacts and squeezes the inclined surface at the bottom end of the T-shaped block 804 located inside the jack 802. Due to the action of the inclined surface, the T-shaped block 804 is pushed into the housing 803, and at the same time compresses the second spring 805. When the conical head 7 is completely inserted into the jack 802, the T-shaped block 804 resets under the elastic force of the second spring 805, and its top surface abuts against the bottom surface of the conical head 7, realizing the positioning of the plug block 801 and preventing the plug block 801 from disengaging upward, and the installation is very convenient.

[0045] When the forklift needs to be disassembled, the AGV lowers the lifting frame. The second mating drive rod 810 moves downward and its bottom end abuts against the ground. The wedge-shaped head at the top end of the second mating drive rod 810 contacts and squeezes the wedge-shaped surface of the second wedge-shaped groove 808 at the bottom of the movable block 807. Under this extrusion, the movable block 807 drives the T-shaped block 804 to move into the housing 803 through the connecting rod 806, so that the T-shaped block 804 is disengaged from the abutting state with the conical head 7. At this time, the plug block 801 can be disengaged from the conical head 7, realizing the quick disassembly of the forklift.

[0046] The above embodiments are only illustrative of the principles and effects of the present utility model and are not intended to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
