Description

Technical Field

[0001] This utility model relates to a lock box, and more particularly to a telescopic lock box for a door frame. Background Technology

[0002] The lock box is an important component installed on the door frame, allowing the bolt, latch, and other components to extend and be stopped. Traditional lock boxes are of fixed size, which can lead to them being too large, too small, or even significantly misaligned with the lock body during installation. There is a lack of products with adjustable lock box sizes that can adapt to installation conditions and prevent damage to wooden door frames. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a telescopic lock box for door frames.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a telescopic lock box for a door frame, comprising a box body, the box body having a lock groove for the lock tongue to extend into, a wire groove on one side of the box body, an inner cavity communicating with the wire groove within the box body, and an external adjustment member movably fitted at one end into the inner cavity. The external adjustment member moves linearly back and forth along the width direction of the box body, and the external adjustment member has at least a limiting part in the inner cavity, the limiting part being limited by a stop connection with the inner cavity wall.

[0005] The bottom of the lock groove is provided with a waist hole, and a fastener is provided at the waist hole.

[0006] The box body has a contact surface on one end face opposite to the lock groove, and at least one end face of the external adjustment member is flush with the contact surface.

[0007] The projection of the external adjustment component in the height direction has a concave shape.

[0008] The bottom of the lock groove is provided with at least two recessed grooves on both sides of the waist hole.

[0009] The beneficial effects of this utility model are: the telescopic lock box for door frames provided by this utility model is simple in design and easy to process. It can be adjusted as needed during operation, has a wide range of applications, and does not require batch production of multiple lock boxes with fixed width specifications, thus meeting various production and usage needs. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0011] like Figure 1As shown, a telescopic lock box for a door frame includes a box body 1. The box body 1 has a lock groove 2 for the lock tongue to enter. The box body 1 also has a wire groove on one side. The box body 1 also has an inner cavity communicating with the wire groove. It also includes an external adjustment member 3, one end of which is movably assembled in the inner cavity. The external adjustment member 3 moves linearly back and forth along the width direction of the box body 1. The external adjustment member 3 has at least a limiting part in the inner cavity. The limiting part is limited by a stop with the inner cavity wall. The lock groove 2 is a mature technology design and will not be elaborated or limited here. The wire groove design is to facilitate the passage of the external adjustment member 3 and also to play a certain horizontal limiting role. It can also be adjusted as needed in actual production. The design of the limiting part prevents the external adjustment member 3 from easily detaching. It can also be designed with variations that do not deviate from the essence. At the same time, the specific position of the limiting part can be the end or other design positions that meet the requirements. The design of the inner cavity provides sufficient space for the partial movement of the external adjustment member 3.

[0012] The bottom of the locking groove 2 is provided with a waist hole 4, and a fastener 5 is provided at the waist hole 4. The waist hole 4 is designed to facilitate installation and connection, and can also increase the installation tolerance. It will not be elaborated or limited in detail here. The fastener 5 is generally a threaded part, which is conducive to quick assembly. The end face of the box body 1 opposite to the opening of the locking groove 2 is the contact surface, and at least one end face of the external adjustment member 3 is flush with the contact surface. The external adjustment member 3 can be on the same plane as the contact surface, which is conducive to improving the installation balance and stability. The projection of the external adjustment member 3 in the height direction has a concave shape. The concave shape is one embodiment and not the only limitation. It is sufficient to meet the design and use requirements. The bottom of the locking groove 2 and on both sides of the waist hole 4 are provided with at least two recessed grooves 6, which not only strengthen the structural strength, but also help to increase the pressure on the contact surface, indirectly improving the anti-slip and anti-displacement effect.

[0013] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. At the same time, the basic principles, main features, and advantages of this utility model have been shown and described above, which should be understood by those skilled in the art.
