Description

Technical Field

[0001] This utility model relates to the field of door lock body application technology, and in particular to a structurally stable magnetic lock body. Background Technology

[0002] Due to the high frequency of traffic in commercial buildings, hospitals, schools, and similar locations, which require frequent opening and closing of doors, magnetic locks are increasingly being used in these places. Magnetic locks offer advantages such as good responsiveness, ease of installation, and a simple overall design. However, in practical applications, it has been found that inside the magnetic lock, when the connecting rod pushes the bolt, it needs to come into close contact with the positioning pin during the transmission of motion. After a certain period of use, inaccurate positioning of the connecting rod occurs, resulting in ineffective travel during transmission. This causes a deviation between the bolt's entry and exit position and the standard setting, leading to discontinuous damping during manual opening and a decreased user experience. Utility Model Content

[0003] The technical solution of this utility model is as follows: A structurally stable magnetic lock body includes a bottom shell and a transmission tooth, a transmission plate, and a moving rod installed inside it. The characteristic is that: a contact block and a transmission end rod are provided on the outside of the transmission plate, a second transmission end plate is provided on the outside of the transmission tooth, the transmission end plate is in close contact with the contact block, and the transmission end rod is in close contact with the moving rod, so that the transmission tooth rotates to drive the transmission plate, and the moving rod is controlled to move through the transmission plate.

[0004] Optionally, a main shaft nut is provided inside the transmission gear, and a handle mounting shaft hole is provided in the center of the main shaft nut. A first spring is provided on the outer side between the main shaft nut and the transmission gear. A first positioning post is also provided inside the bottom shell, and one end of the first spring abuts against one side of the first positioning post.

[0005] Optionally, a second positioning post is also provided inside the bottom shell, and a second spring is provided in the middle of the conductive plate. The second spring is sleeved on the second positioning post, and the conductive plate rotates around the second positioning post as a whole. This technical solution, considering that the conductive plate undergoes high-frequency reciprocating rotation within the entire lock body, effectively solves the problem of inaccurate bolt positioning caused by friction transmission through the positioning post within conventional lock bodies.

[0006] Optionally, a return spring is provided at one end of the moving rod, and a limiting mounting groove is provided at one end of the return spring. A top cover is also provided on the upper part of the bottom shell, and a protrusion is provided inside the top cover. The top cover is fastened to the upper part of the bottom shell, and the protrusion is inserted into the limiting mounting groove. This technical solution takes into account that the return spring will reciprocate through compression and extension due to the movement of the locking tongue. Considering the return spring's inherent compressibility and extensibility, and the accuracy of its return to its original position, the protrusion installed inside the limiting mounting groove provides actual constraint and limitation to the end of the return spring, ensuring that the return spring can still be limited even after long-term use.

[0007] Optionally, a locking tongue block is provided at the lower part of the movable rod, and there are fixing protrusions on both sides of the outer side of the locking tongue block. The fixing protrusions are inserted into the through holes on the outer side of the movable rod.

[0008] Optionally, a first limiting end post and a second limiting end post are provided on one side of the bottom of the movable rod. A guide block is provided on the first limiting end post, and a movable limiting cavity is also provided on the bottom shell. The guide block reciprocates within the movable limiting cavity, and the movable stroke range of the transmission end rod is the rectangular space area formed between the first and second limiting end posts. Using this technical solution, the guide block reciprocates within the movable limiting cavity. It should also be noted that, because the movable limiting cavity is a rectangular structure, the guide block is influenced by the rectangular structure during movement, ensuring that the direction of its movement is always constrained and that its direction of travel does not deviate.

[0009] Optionally, a fixing plate is provided on the lower outer side of the locking tongue block, and circular through holes are provided on both horizontal sides of the fixing plate for fixing the fixing plate to the door body.

[0010] Optionally, the fixed mounting plate has an overall elliptical structure and is formed by one-time metal stamping.

[0011] Optionally, a fixing post is provided on one side inside the fixing mounting plate. The fixing post has threaded holes at both the upper and lower parts to facilitate bolts to pass through and lock between the upper and lower parts of the fixing post.

[0012] Optionally, the thickness of each of the conductive end rods is less than the thickness of the first limiting end post and the second limiting end post.

[0013] Compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] In this invention, through an innovative overall design of the lock body, the transmission teeth, the guide plate, and the moving rod are sequentially and smoothly connected. In particular, the guide plate employs a fixed-point reciprocating motion, ensuring smooth contact and connection between the guide plate and the transmission teeth and the moving rod, preventing displacement during prolonged use. Furthermore, for the moving rod, the guide block within the movement limiting cavity constrains its movement direction, achieving fixed-direction reciprocating motion. The overall internal structure of the lock body is simpler, its internal operation is more stable, and the effective service life of the entire lock body is extended. Attached Figure Description
