Description

Technical Field

[0001] The utility model relates to the field of door locks, in particular to an assembly structure of a lock tongue in a lock body. Background Art

[0002] The latch bolt on the door lock completes the function of closing the door leaf and the door frame. By contracting the latch bolt, the door leaf can rotate around the door axis to achieve the effect of opening the door, and by extending it outside the lock body, the door leaf and the door frame are fixed in position, and the door can be closed. The traditional connection between the latch bolt rod and the latch bolt block is generally spot welded, or after the latch bolt rod and the latch bolt block are connected, a channel is opened at the connection between the two by a punching machine, and then the two are riveted together by rivets. The traditional connection method is not only complicated in process and difficult to operate, but also has high cost and low stability, which can easily cause the lock bolt to quickly separate from the latch bolt rod, thereby causing the lock body to not work properly. Utility Model Content

[0003] In view of the defects of the existing lock tongue assembly structure, the technical problem to be solved by the utility model is to provide an assembly structure of the lock tongue in a lock body which is convenient and quick to assemble, reduces the cost and has a high degree of stability.

[0004] In order to achieve the above-mentioned purpose, according to one aspect of the utility model, the utility model is implemented through the following technical measures: an assembly structure of a lock tongue in a lock body, including an inclined tongue rod and an inclined tongue block, a cylinder is provided at one end of the inclined tongue rod, a fixing part is provided at one end of the cylinder, a connecting hole is provided on the inclined tongue block, and after the cylinder passes through the connecting hole, the inclined tongue rod is connected and fixed to the inclined tongue block through the fixing part.

[0005] Furthermore, a cylindrical hole is provided inside the cylindrical body, and the outer edge of the cylindrical hole is enlarged to form a fixing portion.

[0006] Furthermore, the inner diameter of the connecting hole on the oblique tongue block matches the outer diameter of the cylinder of the oblique tongue rod.

[0007] Compared with the prior art, the advantages of the utility model are: an assembly structure of the lock tongue in the lock body avoids spot welding or rivet riveting, and the assembly is convenient and quick, reducing the cost of labor and materials; the inclined tongue rod and the cylinder are integrally formed and are not easy to separate, the inner diameter of the connecting hole on the inclined tongue block is consistent with the outer diameter of the cylinder of the inclined tongue rod, and after the cylindrical hole is enlarged to form a fixed part, the force is uniform, the inclined tongue rod and the inclined tongue block are firmly fixed, ensuring that the inclined tongue block will not produce relative displacement with the inclined tongue rod during operation.
