Description

Technical Field

[0001] The utility model relates to the technical field of locks, in particular to a double-opening lock core structure. Background Art

[0002] The lock core is the main part that controls the opening of the lock. It is the heart of the lock. It is the core part that can rotate and drive the bolt to move when matched with the key. Some existing locks are usually composed of a lock case and two horizontally arranged lock cores. The two lock cores are connected to the lock fork through an internal component. The medicine key can be opened from both sides. This two-way unlocking method is more common.

[0003] The existing double-opening lock core structure still has some problems when in use. First, since the existing double-opening lock core structure has many internal components, but the medicine key insertion hole is still exposed to the outside, dust is easy to enter during use in the external environment, which is easy to cause wear and tear on the internal structures. If there is a problem on one side, the other side will be affected. In this way, the service life of the lock core is also reduced, and the cost of replacement, cleaning and maintenance is also high. Secondly, in rain or a relatively humid environment, the lock hole is also easy to introduce water vapor into the lock core to cause corrosion to the internal structure, affecting the use of the lock core and reducing the use effect of the lock core.

The use of the above-mentioned components, through the elastic recovery effect of the compression air bag 401, continuously pushes the sealing arc plate 403 and the arc extrusion pad 406 to seal the insertion hole 6, plays an automatic dustproof role, improves the service life of the lock core, and reduces the maintenance and replacement cost. Example 2

[0032] Combination Figure 2 and Figure 3 As shown, based on the first embodiment,

[0033] Specifically, the guide holes 408 are evenly opened on the outer side of the sealing arc plate 403, the adsorption channel 407 and the guide holes 408 are connected to the interior of the compression airbag 401 through the adsorption hole 402, the drying cotton 405 is filled in the interior of the compression airbag 401, and one end of the sealing arc plate 403 passes through the protective clamp ring 5 and is located inside the plug hole 6.

The arc-shaped setting of the sealing arc plate 403 and the arc-shaped extrusion pad 406 also facilitates the insertion of the medicine spoon into the lock core without being affected, so as to play the role of automatic sealing protection. At the same time, the dustproof effect is improved, the wear and tear of dust is reduced, the service life is increased, and the maintenance cost is also reduced. Secondly, during use, if there is accumulation of water vapor in the jack, the water vapor can be introduced into the compressed air bag 401 through the guide hole 408 and the adsorption channel 407 and the adsorption hole 402, and is absorbed by the drying cotton 405. In the process of the medicine key being inserted into the lock core and continuously used, the compressed air bag 401 is continuously compressed and inhales and exhales air, and the water vapor is air-dried. This not only has a moisture-proof effect and reduces the corrosion of water vapor, but also improves the use effect of the lock core.
