The utility model has reasonable structure, the box body and the fixed guide plate are in compression contact by the compression spring, the contact of the box body and the fixed guide plate can be separated by pressing the box body forcefully during adjustment, the continuously and uniformly undulating thin toothed bars on the contact surface of the box body and the fixed guide plate can be accurately matched and positioned, the adjustment of the position of the box body is very convenient, tools are not needed, and the positioning of fine adjustment is also very accurate.

Description

Door lock catch box

Technical Field

The present utility model relates to a door lock box which is installed in a door frame and is matched with a lock tongue of a door lock to lock.

Background

When the door lock is locked, the lock tongue extends into a buckle box arranged in the door frame. Because the door lock is fixed in the door leaf, in order to ensure proper matching of the positions of the lock tongue and the buckling box, the buckling box is generally required to be adjustable in position. The existing door lock buckling box is characterized in that the box body is connected to the fixed guide plate through screws, the screws are loosened to move the box body to be fastened again during adjustment, tools are used for carrying out the door lock buckling box, the operation is inconvenient, and the fine adjustment position is not easy to accurately position.

Disclosure of Invention

Aiming at the defects of the prior art, the utility model provides the door lock buckle box which has reasonable structure and convenient adjustment.

The utility model comprises a fixed guide plate provided with a large through hole, wherein the back surface of the fixed guide plate is connected with a back plate at intervals, a box body is arranged in a space between the fixed guide plate and the back plate, an opening of the box body faces the large through hole, a compression spring is padded between the box body and the back plate, the front surface of the box body is in close contact with the inside of the fixed guide plate, and fine toothed bars which continuously and uniformly undulate are arranged on the contact surfaces of the front surface of the box body and the back plate and are matched with each other to form a box body position adjustable structure.

The utility model has reasonable structure, the box body and the fixed guide plate are in compression contact by the compression spring, the contact of the box body and the fixed guide plate can be separated by pressing the box body forcefully during adjustment, the continuously and uniformly undulating thin toothed bars on the contact surface of the box body and the fixed guide plate can be accurately matched and positioned, the adjustment of the position of the box body is very convenient, tools are not needed, and the positioning of fine adjustment is also very accurate.

The utility model is further described below with reference to the drawings and examples.

Fig. 2 is a cross-sectional view A-A of fig. 1.

Fig. 3 is a front view of the case of fig. 1.

Fig. 4 is a rear view of the fixed guide plate of fig. 1.

Detailed Description

As shown in fig. 1 to 4, the fixed guide plate 1 is provided with a large through hole 3, the back space of the fixed guide plate 1 is connected with a back plate 4, the box body 2 is arranged in the space between the fixed guide plate 1 and the back plate 4, and the box body 2 is opened towards the large through hole 3. Compression springs 5 are arranged between the box body 2 and the back plate (4), and the number of the compression springs 5 is generally multiple. The front surface of the box body 2 is in close contact with the inside of the fixed guide plate 1, and the contact surfaces of the front surface and the fixed guide plate are provided with continuous and uniform undulating thin toothed bars 6 which are matched with each other to form a box body position adjustable structure.

When the device is used for adjusting, the box body 2 is pressed by force to enable the compression spring 5 to contract, and the front surface of the box body 2 and the inside of the fixed guide plate 1 can move out of contact. After the pressing force is removed, the compression spring 5 is restored to be compressed. The front surface of the box body 2 and the inside of the fixed guide plate 1 are provided with continuous and uniform undulating thin toothed bars 6, and the peaks and the troughs of the two are mutually matched and positioned, so that fine and accurate positioning can be performed.

In this embodiment, the limiting bump 8 is arranged on the inner side wall of the fixed guide plate 1 and near the upper and lower edges of the large through hole 3, and the upper and lower side walls of the box body 2 are correspondingly provided with the stop blocks 9 to cooperate, so that the box body 2 can be prevented from being separated by oversized displacement. In addition, the magnet 7 can be fixed in the box body 2, so that the common mechanical door lock can be used, and the magnetic door lock can be also suitable for a magnetic door lock to attract a lock tongue.

Claims
