the handle is fixedly connected to the case and positioned below the tail end of the lock catch;

at least one micro switch is arranged in the case and at a position within the rotation range of the lock catch, and the lock catch touches the corresponding micro switch in the rotation process to generate a corresponding line clamp signal;

the locking component is connected to the handle and used for locking the position of the lock catch; when the locking component acts on the lock catch, the hook part at the front end of the lock catch is buckled into the corresponding lock hole on the case.

Further, at least one damping spring is connected between the case or the handle and the lock catch.

Further, the locking component comprises a base, a guide shaft, a compression spring and a rotary sleeve; the base is fixedly connected to the tail end of the handle, the guide shaft is vertically and fixedly connected to the base along the vertical direction and is fixedly locked through the lower limiting piece, the rotary sleeve is rotationally connected to the guide shaft, the compression spring is sleeved on the guide shaft, two ends of the compression spring respectively prop against between the bottom of the rotary sleeve and the top of the lower limiting piece, and an upper limiting piece is fixed to the top of the guide shaft and used for limiting the rotary sleeve to be separated from the guide shaft upwards; the side of the rotary sleeve is provided with a stop block, the stop block is propped up against the bottom of the tail end of the lock catch under the action of the compression spring, so that the hook part at the front end of the lock catch is buckled into the corresponding lock hole on the case, and the locking and positioning of the lock catch are realized.

Further, the lower limiting part is a nut or an E-shaped clamp spring.

By adopting the technical scheme, the utility model can achieve the aims of locking the line card, triggering the micro switch and preventing false touch. The depth dimension based on the locking mechanism can be adjusted, but the thickness dimension can be very thin, so that the space of the line card panel is not occupied, and the handle can be conveniently operated. The utility model has simple and practical structure and can solve the specific design scene.

Detailed Description

As shown in fig. 1-5, the line card locking mechanism of the utility model comprises a lock catch 1, a handle 2, a rotating shaft 3 and a locking component 4.

The rotating shaft 3 is fixedly connected to the chassis, a pivot hole in the middle of the lock catch 1 is rotationally connected to the rotating shaft 3, and a hook part 11 is arranged at the bottom of the front end of the lock catch 1;

the handle 2 is fixedly connected to the case and is positioned below the tail end of the lock catch 1;

at least one micro switch 5 is arranged in the case and at a position within the rotation range of the lock catch 1, and the lock catch 1 touches the corresponding micro switch 5 in the rotation process to generate a corresponding line clamp signal;

the locking component 4 is connected to the handle 2 and is used for locking the position of the lock catch 1; when the locking component 4 acts on the lock catch 1, the hook part 11 at the front end of the lock catch 1 is buckled into the corresponding lock hole on the case.

At least one damping spring 6 is connected between the case or handle 2 and the lock catch 1. As shown in fig. 1, a damping spring 6 is connected between the chassis and the latch 1. As shown in fig. 2-4, a damping spring 6 can be added between other positions of the chassis and the lock catch 1, or the damping spring 6 can be added between the handle 2 and the lock catch 1.

The lock catch 1 is limited by the damping spring 6 in the rotating process, so that a damping sense is generated.

Wherein the locking assembly 4 comprises a base 41, a guide shaft 42, a compression spring 43 and a rotary sleeve 44; the base 41 is fixedly connected to the tail end of the handle 2, the guide shaft 42 is vertically and fixedly connected to the base 41 in a vertical mode and is fixedly locked through a lower limiting piece 421 (the lower limiting piece 421 can be a nut or an E-shaped clamp spring), the rotary sleeve 44 is rotationally connected to the guide shaft 42, the compression spring 43 is sleeved on the guide shaft 42, two ends of the compression spring 43 respectively prop against the bottom of the rotary sleeve 44 and the top of the lower limiting piece 421, an upper limiting piece 422 is fixed to the top of the guide shaft 42, and the upper limiting piece 422 is used for limiting the rotary sleeve 44 to be separated from the guide shaft 42 upwards; the side of the rotary sleeve 44 is provided with a stop block 45, and the stop block 45 is propped up against the bottom of the tail end of the lock catch 1 under the action of the compression spring 43, so that the hook part 11 at the front end of the lock catch 1 is buckled into a corresponding lock hole on the case, and the locking and positioning of the lock catch 1 are realized.

The working principle of the utility model is as follows: the rotary sleeve 44 is rotated to separate the stop block 45 from the tail end of the lock catch 1, then the tail end of the lock catch 1 is pressed, the micro switch 5 is triggered in the rotation process of the lock catch 1, so that the stop block 45 is propped up against the bottom of the tail end of the lock catch 1 under the action of the compression spring 43 by rotating the rotary sleeve 44 after the line card module is inserted, the hook 11 at the front end of the lock catch 1 is buckled into a corresponding lock hole on a case, locking and positioning of the lock catch 1 are realized, and false touch is prevented.

While particular embodiments of the present utility model have been described above, it will be understood by those skilled in the art that this is by way of example only, and that various changes and modifications may be made to this embodiment without departing from the spirit and scope of the utility model, but these changes and modifications are within the scope of the utility model.
