Clamp for relieving locker locking state

Abstract

The invention provides a clamp for relieving the locker locking state. The clamp comprises a clamp body, a lifting screw, a baffle and a hook plate. A lifting screw with the lower end abutting againstthe top end of a locker bolt head is vertical screwed to the middle of the clamp body, a clamping groove is formed in one side of the clamp body, the baffle and the clamp body are fixedly connected so that a front opening of the clamping groove can be blocked and openings in the two ends of the clamping groove are opened, the upper end of the hook plate and the clamping groove are matched and hooked, and the lower end of the hook plate and the lower portion of a middle block of the locker are in interference fit, are hooked and are screwed through the lifting screw so that the clamp body canmove upwards slowly to drive the middle block of the locker to be loosened and unlock the locker locking state. The locker locking state can be conveniently relieved, the phenomenon that the middle block is clamped when the locker locking state is relieved is effectively avoided, the adjusting and maintaining work is simplified, during batched adjusting and maintenance, operation procedures are simplified, the production cycle is shortened, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of clamp devices, and in particular relates to a clamp for releasing the locking state of a locking device. Background technique [0002] The circuit board lock (mainly refers to the 201 type locking device) has the characteristics of convenient installation, convenient use, and firm fixation, and is widely used in electronic products for fixing circuit boards. During debugging or maintenance, after the circuit board locker is locked, it is necessary to release the locked state to pull the circuit board out of the fixing slot, such as Figure 7 shown. When the bolts on the locker are loosened, if Figure 8 As shown, the upper block 8 can be easily loosened with the bolts, but the middle block 9 of the locking device is still tightly fastened between the fixing groove wall and the lower block 10 due to no upward force, even if the bolts are loosened, the middle block 9 cannot be If it is loose, the circuit ...

AI Technical Summary

Problems solved by technology

When the bolts on the locker are loosened, if Figure 8 As shown, the upper block 8 can be easily loosened with the bolts, but the middle block 9 of the locking device is still tightly fastened between the fixing groove wall and the lower block 10 due to no upward force, even if the bolts are loosened, the middle block 9 cannot be Loose, so that the circuit board cannot be taken out normally

At present, two methods are used to solve this problem: one is to use a flathead screwdriver to pry on the side of the locking device close to the box wall, and then pry on the other side of the locking device close to the box wall, prying back and forth to make the circuit board left and right Shake to loosen block 9 in the locking device

The disadvantages of this method are: 1. The lower part of the circuit board is the plug-in row (pin or hole) that is connected to the base plate (pin or hole). Shaking from side to side can easily cause mechanical damage to the roots of the pins or holes in the plug-in row when shaking. ; 2. Left and right prying will cause irreparable surface damage to the locker and the surface of the box body; the second is to make a hook, hook the lower part of the locker middle block 9 in the locked state, and pull it up to release the lock tight state

The disadvantages of this method are: 1. If the upward force of the hook is too small, the lifting force will not move, and if the force is too large, it will easily damage the locker and the surface of the circuit board; 2. The upward force of the hook cannot be kept in line with the locker. Parallel, damage the slideway of the locker and easily deform the middle block
