Description

Technical Field

[0001] The utility model relates to the technical field of door lock parts, in particular to a latch bolt structure. Background Art

[0002] Door locks are necessities in our lives. In addition to being the first line of defense for home safety, they are also an especially important line of defense for safety in hotels. The lock body is one of the important parts of the lock. It plays the role of closing and opening in the lock and is mainly responsible for anti-theft work. The latch bolt is one of the important components of the lock body, and its role cannot be ignored.

[0003] The inclined tongue rod in the existing door locks is mostly an integrally formed structure with a simple structure, which is not easy to extend or shorten and should be used with locks of different specifications, resulting in poor flexibility and a small scope of use. Utility Model Content

[0004] The utility model aims to solve the problems that the inclined tongue rods in the existing door locks are mostly one-piece structures with simple structures, which are not easy to extend and shorten and can be used with locks of different specifications, resulting in weak flexibility and a small scope of use. A inclined tongue rod structure is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A latch bolt structure, comprising:

[0007] A rod body, wherein a first connecting column is connected to the bottom of the rod body, and a second connecting column is installed on the top of the rod body, a sleeve is sleeved on the outer wall of the second connecting column, and a key groove is opened on the outer wall of the sleeve, a threaded area is arranged below the outer wall of the second connecting column, and a reserved groove is opened on the top of the second connecting column.

[0008] Preferably, the first connecting column and the rod body are an integrally formed structure.

[0009] Preferably, the second connecting column forms a detachable structure with the rod body through the threaded area.

[0010] Preferably, the sleeve is movably connected to the outer wall of the second connecting column.

[0011] Preferably, the inner side of the reserved groove is in a cross-shaped structure, and the reserved groove forms an integrated structure with the second connecting column through the slotting.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0013] 1. In the utility model, by setting the second connecting column, the sleeve and the keyway, people can rotate the second connecting column so that it can extend to different lengths between the second connecting column and the rod body, which is convenient for meeting locks of different specifications, and can effectively improve the flexibility of the inclined tongue rod and expand its scope of use. At the same time, through the dual limitation of the reserved groove and the keyway, the horizontally arranged inclined tongue rod is not easy to rotate radially when it moves left and right. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 2 This is a schematic diagram of the back structure of the second connecting column in the utility model;

[0016] Figure 3 It is a schematic diagram of the top view of the second connecting column in the utility model.

[0017] Legend:

[0018] 1. Rod body; 2. First connecting column; 3. Second connecting column; 4. Sleeve; 5. Keyway; 6. Threaded area; 7. Reserved groove. DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Reference Figure 1-3A latch bolt rod structure includes a rod body 1, a first connecting column 2 is connected to the bottom of the rod body 1, and a second connecting column 3 is installed on the top of the rod body 1. The first connecting column 2 and the rod body 1 are an integrally formed structure. By connecting the first connecting column 2 with the lock tongue, and the first connecting column 2 and the rod body 1 are integrally formed, it is convenient to enhance the force bearing capacity. The second connecting column 3 and the rod body 1 form a detachable structure through a threaded area 6. By holding the rod body 1 and rotating the second connecting column 3, it is possible to extend and shorten the rod body 1, which is convenient for meeting different specifications of locks, can effectively improve the flexibility of the latch bolt rod, and can expand its scope of use. The outer wall of the second connecting column 3 is provided with a sleeve The sleeve 4 is provided with a key slot 5 on its outer wall, and the sleeve 4 and the outer wall of the second connecting column 3 are movably connected. By sleeve 4 being sleeved on the middle part of the outer wall of the second connecting column 3, the key slot 5 can contact the protrusion at the lock, so that when people rotate the second connecting column 3 to adjust the length, the key slot 5 can slide along the outer side of the protrusion without causing motion interference. A threaded area 6 is provided at the lower part of the outer wall of the second connecting column 3, and a reserved slot 7 is provided at the top of the second connecting column 3. The inner side of the reserved slot 7 is a cross-shaped structure, and the reserved slot 7 forms an integrated structure with the second connecting column 3 through the slotting. The reserved slot 7 with the cross-shaped structure can be conveniently connected to the boss inside the lock.

[0021] Working principle: When in use, the staff first extends the first connecting column 2 into the lock tongue and connects it, and connects the end of the second connecting column 3 to the boss, and sets the spring on the outside of the rod body 1, so that the combination is placed inside the lock for use. At the same time, by holding the rod body 1 and rotating the second connecting column 3, the threaded area 6 set at one end of its outer wall is threadedly connected to the rod body 1, thereby completing the extension and shortening operation between the rod body 1 and the second connecting column 3, which is convenient for meeting locks of different specifications, and can effectively improve the flexibility of the inclined tongue rod. Through the connection between the reserved groove 7 and the boss, and the connection between the keyway 5 and the protrusion on the inner wall of the lock, a double limitation is formed, so that the transversely arranged inclined tongue rod is not easy to rotate radially when it moves left and right.

[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
