AI Technical Summary
The side-pull battery structure of the electric forklift requires an air hook to fix the hatch door during maintenance. However, the air hook collided with the hatch door due to vibration during operation, causing noise and possible decoupling.
A wind hook device with self-locking function is designed. By installing a self-locking nut and a lower self-locking nut on the threaded shaft of the air hook body, and installing a spring between the threaded shafts, the self-locking function of the air hook is realized.
The device can remain fixed when the air hook vibrates, avoid noise caused by collision with the hatch door, and improve safety and prevent decoupling problems.

Description
Technical Field
[0001] The utility model relates to the technical field of forklifts, in particular to a wind hook device with a self-locking function. Background Art
[0002] The electric forklift is equipped with a side-pull battery structure and a battery compartment door on one side. When the compartment door is opened for maintenance, it is necessary to use a wind hook to fix the compartment door to prevent it from closing automatically due to wind force and causing injury to maintenance personnel. In the original solution, after the wind hook is retracted, the wind hook will collide with the compartment door due to vibration when the forklift is running, generating noise and causing unhooking problems. To solve the above problems, a wind hook device with a self-locking function is designed. Utility Model Content

[0014] Reference Figure 1-3 A wind hook device with a self-locking function includes a hatch, a wind hook seat 1 and a fixing seat 10 are fixed at equal height positions on the side walls of the hatch, a wind hook body 2 is arranged between the wind hook seat 1 and the fixing seat 10, and a threaded shaft 2-1 and a wind hook shaft 2-2 are respectively provided at both ends of the wind hook body 2. An upper self-locking nut 4 and a lower self-locking nut 5 are threadedly installed on the surface of the threaded shaft 2-1, and a spring 3 is mounted on the surface of the threaded shaft 2-1 and between the upper self-locking nut 4 and the lower self-locking nut 5. By assembling the spring 3, the wind hook body 2 can adapt to upward movement when practical, which is convenient and practical. By rotating the length of the spring 3 of the upper self-locking nut 4 and the lower self-locking nut 5, the force intensity of the wind hook body 2 when moving can be adjusted.
[0015] A docking hole is provided on the surface of the fixing seat 10, and a silent sleeve 9 is fixed inside the docking hole. A mounting hole is provided on the surface of the wind hook seat 1, and the threaded shaft 2-1 is docked with the wind hook seat 1, and the wind hook shaft 2-2 is docked with the fixing seat 10.
[0016] The upper self-locking nut 4 and the lower self-locking nut 5 are respectively installed on the upper and lower sides of the wind hook seat 1.
[0017] A first baffle 6 is set between the upper self-locking nut 4 and the upper surface of the wind hook seat 1, a second baffle 7 is set between the top of the spring 3 and the wind hook seat 1, and a third baffle 8 is set between the bottom of the spring 3 and the lower self-locking nut 5.
[0018] When the device is used, the hook seat 1 is fixed on the hatch, the fixing seat 10 is fixed on the hatch, the wind hook 2 is provided with a threaded shaft 2-1 at one end and a wind hook shaft 2-2 at the other end; holes are provided on the wind hook seat 1 and the fixing seat 10, and the distance between the two holes is equal to the wheelbase length between the wind hook 2 threaded shaft 2-1 and the wind hook shaft 2-2; the wind hook threaded shaft 2-1 is provided with a self-locking nut 4 and a baffle 6; the wind hook thread 2-1 is inserted into the wind hook seat 1; the baffle 7, the spring 3, the baffle 8, and the self-locking nut 5 are sequentially arranged on the wind hook 2-1 thread from top to bottom; the self-locking nut 5 is pre-tightened upwards to make the spring 3 The wind hook 2 is lifted upwards, and the threaded shaft 2-1 and the wind hook shaft 2-2 of the wind hook 2 slide upwards along the holes provided on the wind hook seat 1 and the fixed seat 10 respectively. The spring 3 is compressed, and the wind hook shaft 2-2 is disengaged from the fixed seat 10. The wind hook shaft 2-2 can be inserted into the fixed seat at the vehicle end to prevent the hatch from being accidentally closed. Before actively closing the hatch, the wind hook shaft 2-2 is first lifted and inserted into the silent sleeve 9 provided in the fixed seat 10. The spring 3 still has rebound force, which can lock the wind hook 2 on the hatch to achieve self-locking.
