Lock pin

Abstract

The invention discloses a lock pin. The lock pin comprises a base block and a pin bolt; the base block is divided into an upper portion and a lower portion, the lower portion is provided with an external thread, the base block is provided with a through hole, and the through hole penetrates the base block in the direction from the upper portion to the lower portion; the pin bolt is provided with a lock portion and a connecting portion, the pin bolt is movably sleeved with the through hole, the pin bolt moves to the second position from the first position according to the moving path, and the connecting portion is exposed out of the upper portion; according to the first position, the lock portion is hidden in the through hole, and according to the second position, the lock portion is exposed out of the lower portion; the work state of the lock pin is stable, and no matter whether the lock pin is in the locking state or the unlocking state, the lock pin is not likely to fail due to vibration or scratching; the lower portion of the base block can be fixed to an object through the thread and is not likely to fall off, the lock pin is kept locking under the effect of the elastic structure, under the effect of a clamping groove and a clamping block, changing of the locking state and the unlocking state is achieved, and when unlocking is achieved, the state cannot be changed by reasons of vibration and the like.

Description

technical field [0001] The invention relates to mechanical parts, in particular to a locking pin. Background technique [0002] The mechanism of the currently used locking pin is as follows: figure 1 As shown, including the pin 1' and the ring 2' connecting the pins, the locking pin is inserted into the holes of two objects, the two objects are respectively called the first part A and the second part B, in order to limit their movement, it is necessary to move to pull out the locking pin. [0003] The operation of this kind of locking pin is relatively complicated, and it is necessary to manually control the position of the device, and insert it after alignment. If the hole position is misaligned when pulling out, it may make it difficult to pull out the pin; and the self-locking function cannot be realized. Under normal circumstances, it may pop out, and the locking function cannot be realized; it is attached to the production equipment, resulting in an unattractive and s...

[0003] The operation of this kind of locking pin is relatively complicated, and it is necessary to manually control the position of the device, and insert it after alignment. If the hole position is misaligned when pulling out, it may make it difficult to pull out the pin; and the self-locking function cannot be realized. In some cases, it may pop out, and the locking function cannot be realized; it is attached to the production equipment, resulting in an unattractive and simple appearance, and it is easy to scratch when people or vehicle equipment pass by, causing the pin to be pulled out
