The disadvantage of this solution is that it is not possible to mount and dismount the module group on the front of the chassis.
Disclosure of utility model
The utility model provides a front maintenance lock which can be used for installing and detaching a module group on the front surface of a chassis under the condition that only front maintenance can be performed, wherein a tool hole is required to be designed on a module, and a maintenance tool is used for penetrating the module to operate the front maintenance lock; in situations where rapid installation and removal of the module set is required, such as in a court screen.
The utility model provides the following technical scheme: a front maintenance module lock comprising:
The locking mechanism comprises a lock tongue and a fixed base, the fixed base is arranged at the bottom of the front maintenance module lock, and the lock tongue is arranged at the top of the fixed base;
The connecting mechanism comprises a rotating shaft and a spring, wherein the rotating shaft penetrates through the lock tongue and the fixed base; the spring is arranged at the top of the lock tongue and sleeved on the rotating shaft; a lock hole is formed in the plane of one end, close to the fixed base, of the rotating shaft;
The limiting mechanism comprises a rotating rod and a limiting gasket, wherein the limiting gasket is arranged above the spring, the rotating rod is pressed on the limiting gasket, and the rotating rod is connected to the rotating shaft. The lock hole is arranged on the plane at one end of the rotating shaft, the plane can ensure that the position of the lock hole basically cannot move, and a maintenance tool can be inserted into the lock hole and rotated more easily during maintenance. One end of the rotating shaft far away from the lock hole is provided with a through hole, and a base, a lock tongue and a spring are arranged in the distance between the through hole and the end face of the lock hole, so that a certain distance is reserved. Too far and too close, too close to the plug or too dead of the spring pressure causes the rotation of the spindle to be difficult, and too far the spring will twist, thus the locking effect is not realized. The base is connected with the module, the limiting gasket presses the spring, the rotating rod presses the limiting gasket, the spring is compressed at a proper height, and the spring is required to give a certain pressure to the lock tongue, so that the rotation of the rotating shaft is smoother.

The bending part is used for facilitating the bolt to climb up the chassis when the chassis is higher than the module (seen from the back view), and certainly the chassis can be clamped without the bending part when the chassis is lower than the module. The bending part can be triangular, so that the bending part is better processed and needs to reach a certain height. The position of the bending part is the position which is contacted with the chassis first in the process of locking the chassis.
Further, the bending angle of the bending part is an obtuse angle; the bending part and the lock tongue are of an integrated structure. The angle of bending of the bending part is the angle formed by the bending part and the lock tongue main body, the bending angle is an obtuse angle, which indicates that the bending part protrudes out of the lock tongue main body, the case can be taken up and rotated when the case is encountered, otherwise, if the bending angle is an acute angle, the effect is lost. The bending part and the lock tongue main body are of an integrated structure, the lock tongue main body and the bending part can rotate by the same angle in the rotating process, and the angle error cannot exist.
Further, a gasket groove is formed in the rotary rod, and the limiting gasket is clamped in the gasket groove. Therefore, the rotary rod cannot move or fall off at will, the spring is always in a basically linear compression state, and the rotary rod can be smoother in rotation.
Further, the position of the lock hole on the rotating shaft is matched with the module. The module is provided with the module through hole, and the lock hole is aligned with the module through hole as much as possible, so that the module can be maintained more conveniently, and the lock hole is not found for a long time. And meanwhile, the lock hole is positioned on the center line of the rotating shaft as much as possible, so that the lock hole can not move in relative position when the rotating shaft rotates.
Further, the fixed base is connected with the module through a connecting piece; the fixed base is provided with a module lock mounting hole for the connecting piece to pass through. The connecting piece can be a bolt, and the bolt passes through a module lock mounting hole on the base and is mounted into a thread on the back of the module, so that the module lock can be connected with the module more tightly by the mounting mode.
