Description

a lock structure

technical field

The utility model relates to the field of machinery, in particular to a locking structure for mechanical equipment with a cover plate structure.

Background technique

With the continuous improvement of the power and processing speed of electronic components, electromagnetic radiation is becoming more and more serious, which requires that all kinds of mechanical equipment used to accommodate electronic components should have a strong shielding function. In existing mechanical equipment, shielding against electromagnetic radiation is generally achieved by using various cover plates.

As a cover plate, it needs to be opened and disassembled frequently, so the way of fixing and opening the cover plate is a very important factor affecting the convenience of the cover plate structure. In the prior art, there are two common ways to fix and open the cover: one is to use screws to fix; the other is to use a buckle structure, that is, to use rotatable quick-release screws on the cover to achieve .

But above-mentioned two kinds of ways all have the shortcoming that self structure is difficult to overcome, specifically as follows: Although the first kind is the simplest in structure, but need to use screwdriver when dismantling, it is not convenient to open frequently; When closing the cover, there are disadvantages that the quick-release screws must be at a specific angle. In addition, this method has too many operating steps, takes up valuable cabinet space, and has limited force on the quick-release screws.

technical content

The utility model provides a reliable and convenient locking structure.

The solution of the utility model is: a lock structure, which is composed of a wrench seat for support, a wrench for fixing the lock, and an elastic body that provides auxiliary external force for fixing and opening the lock. The wrench is installed on On the wrench seat, the elastic body is connected between the wrench and the wrench seat.

The locking structure further includes a screw for limiting the rotation of the wrench, which is installed on the wrench seat.

In addition, a protruding shaft may be provided on the wrench seat, and the wrench is mounted on the protruding shaft; and a screw for limiting the rotation of the wrench is mounted on the protruding shaft.

The structure of the utility model has the following advantages due to the adoption of the above-mentioned technical scheme:

1. It adopts the hook form. When it is applied to the cover plate, the cover plate does not need to be connected by screws and does not need tools. It is very convenient to install and disassemble;

2. The wrench has obvious shape characteristics, and then echoes the shape of the cover plate, showing the shape characteristics of the entire product;

3. When the cover is closed, you only need to push the cover hard without paying attention to the state of the lock. When the cover is opened, you can pull the cover while pulling the lock wrench by hand, and complete the lock opening and closing in one step. The board is opened, which is more comfortable to operate;

4. The space for the lock is on the side of the cover, which does not occupy the front position of the cover, saving space.

Specific implementation

Please refer to Figure 1 and Figure 2, the lock structure of the present utility model includes: a wrench seat (1) for support, a wrench (4) for fixing the lock, and an elastic body (3) that provides auxiliary external force for fixing and opening the lock , wherein, the wrench (4) is mounted on the wrench seat (1), the shape of the wrench (4) is L-shaped, and the end surface of the head is a circular arc surface tangent to a slope transition, adjacent to it It is a groove (5) with a circular bottom surface; the wrench (4) is installed on the protruding shaft (not shown in the figure) of the wrench seat (1), and is limited by the screw (2) when rotating around it ; The clip spring (3) is connected between the wrench (4) and the wrench seat (1). Its one end is sleeved on the raised square column of the wrench seat (1), and the other end is inserted in the round hole of the wrench (4).

The utility model embodiment is installed on the side of the movable cover plate, and a fixed pin is installed on the fixed side plate matched with the cover plate, and its diameter is slightly smaller than the width of the groove (5) on the wrench (4) , when the movable cover is closed, the inclined surface on the wrench (4) is in contact with the cylindrical surface of the pin, and under the external force of closing the cover, the pin presses the inclined surface of the wrench to make the wrench (4) wrap around the wrench seat (1) Protruding shaft rotates, and as shown in Figure 3, compression stage spring (3) simultaneously; Under the action of the compression spring (3), the wrench (4) will rotate in the opposite direction so that the groove (5) snaps into the pin, thereby completing the function of locking and positioning. In this state, the cover will not be opened under the action of external force, and the locking is reliable.

When the cover is to be opened, pull the upper end of the wrench (4) by hand to rotate the wrench (4), the groove (5) on the wrench (4) rotates out of the pin, and the cover is pulled apart under the action of tension .

The embodiment of the utility model can adopt zinc alloy die-casting parts, and the surface is treated with electroplating chromium, so that it not only meets the requirements of use functions, but also has obvious modeling functions.
