Smart spherical lock is the executive component of locking the door in the access control system. It includes an external lock core mechanism and an internal lock core mechanism, wherein the external lock core mechanism is installed on the outside of the door body, and the internal lock core mechanism is installed on the inside of the door body. The external lock core mechanism and the internal lock core mechanism are linked to each other through a connecting shaft. When part of the external lock core mechanism is violently damaged, part of the connecting shaft will be exposed, and the perpetrator can operate the connecting shaft to drive the operation of the unlocking dial wheel, so that the internal lock core mechanism will operate and achieve the purpose of unlocking. The lock body with such a structure is easy to be opened violently, and there is a great safety hazard. Therefore, the present invention applies for a smart spherical lock with an anti-violent damage mechanism. Summary of the invention

The pressing part 40 includes a pressing shaft, and the end of the pressure-bearing part 41 is provided with a pressure-bearing groove 411 for the pressing shaft to contact, and a spring 417 is provided in the pressure-bearing groove, and the spring 417 contacts the end of the pressing shaft. The interior of the inner rotating shell 42 is divided into a main cavity area 420 and a sub-cavity area 421, and the cross section of the main cavity area 420 is larger than the cross section of the sub-cavity area 421. The connection between the main cavity area 420 and the sub-cavity area 421 forms an annular table 422, and the connection between the pressure-bearing part 41 and the pressing part 40 is located in the main cavity area 420. The locking area is a plurality of locking holes 423 distributed along the circumference of the inner rotating shell 42, and the locking holes 423 are connected to the main cavity area 420 of the inner rotating shell 42. The inner lock core mechanism 2 is provided with a slide groove 20 for slidingly engaging the locking member, the locking member is a pin 21, a spring 22 is provided between the pin 21 and the bottom of the slide groove 20, and the spring 22 drives the pin 21 to move toward the inner rotating shell 42. The pressure-bearing portion 41 includes a pressure-bearing end 412 having a pressure-bearing groove 411 and a shaft end 413, the driving member 410 is sleeved on the shaft end 413, one end of which is in conflict with the annular table 422, and the other end of which is in conflict with the pressure-bearing end 412, the shaft end 413 is away from the pressure-bearing end 412, and is penetrated in the sub-cavity area 421 of the inner rotating shell 42, and extends to the outside of the inner rotating shell 42.

[0019] Working principle: When the lock is in a normal state, the pressure-bearing part 41 is subjected to the pressure of the pressing part 40, the spring three 415 on the driving member 410 is in a contracted state, the pin 21 on the locking member and the locking hole 423 on the inner rotating shell 42 are in a staggered state, and the pin 21 is now contracted in the slide groove 20. When the outer lock core mechanism is subjected to violent damage, the pressing portion 40 of the connecting shaft assembly 4 is exposed. At this time, the pressing portion 40 loses its supporting force and no longer applies force to the pressure-bearing portion 41. After the spring three 415 in a contracted state on the driving member 410 is relaxed, it applies force to the driving ring 414. The driving ring 414 drives the pressure-bearing end 412 to move toward the pressing portion 40. The pressing portion 40 drives the inner rotating shell body 42 to move forward through the connecting block 401. At this time, the pin 21 is in a corresponding state with the locking hole 423 on the inner rotating shell body 42. Driven by the spring two 22, the pin 21 is inserted into the locking hole 423 to cooperate, so that the inner rotating shell body 42 cannot rotate and is in a locked state, thereby failing to drive the unlocking dial wheel 3 to move, making the lock difficult to be opened. It has the function of preventing violent damage and improving the safety performance of the lock.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
