Description

An anti-peephole unlocking structure of an electronic lock

technical field

The utility model relates to an electronic lock, in particular to an anti-cat's eye unlocking structure of the electronic lock.

Background technique

At present, door locks sold on the market can be roughly divided into two types, namely mechanical locks and electronic locks. The so-called mechanical lock refers to the mechanical connection between the various parts in the entire lock body. This type of door lock is widely used in life. But the shortcoming that it exists is that security is poor, mainly shows that the key of opening mechanical lock is easy to duplicate, yet the electronic key that is used to open electronic lock is difficult for imitation. The usual structure of the electronic lock unlocking device is: the motor drives the gear to rotate, drives the clutch device, and realizes unlocking through the clutch device.

Electronic locks use non-mechanical keys such as passwords, random codes, two-dimensional codes, fingerprints, magnetic cards, radio frequency cards, TM cards, etc. as user identification IDs, drive the clutch device through the drive unit to unlock, and then drive the clutch device and lock through the handle. Lock body and unlock.

However, the structure of some electronic locks is that it does not need a non-mechanical key to unlock the house. You only need to turn the handle directly to unlock the lock. Therefore, some thieves take advantage of this loophole and use a soft hook to stretch in from the cat's eye and then hook it. The handle is rotated to unlock, so the applicant has designed a kind of anti-peephole unlocking structure of the electronic lock to avoid the above problems.

Contents of the invention

In order to overcome the deficiencies of the prior art, the utility model provides a cat's-eye anti-unlocking structure of an electronic lock.

The technical scheme that the utility model solves its technical problem adopts is:

An anti-peephole unlocking structure of an electronic lock, characterized in that it includes a housing, the housing is provided with a handle connector capable of rotating in the housing, a lock body connector capable of rotating in the handle connector, the lock body The connecting piece is provided with a lock body connecting hole, the handle connecting piece is provided with a handle connecting rod, and the handle connecting rod is provided with a handle connecting hole, and the handle connecting hole is provided with a handle that can slide in it. And the plunger inserted into the lock body connection hole and the reset mechanism that can reset the plunger, the hole bottom of the handle connection hole is provided with a through hole and a button rod that can push the plunger. Button connection.

The connecting hole of the handle and the connecting hole of the lock body are polygonal holes; the insertion rod is a matching polygonal rod.

The connecting hole of the handle and the connecting hole of the lock body are regular hexagonal holes; the insertion rod is a matching regular hexagonal rod.

The reset mechanism includes a mounting hole arranged in the insertion rod, a reset spring is arranged in the mounting hole, one end of the reset spring is in contact with the bottom of the mounting hole, and the other end of the reset spring is in contact with the connecting hole of the lock body. hole bottom contact.

The return spring is a compression spring.

The beneficial effects of the utility model are: the utility model adds a button on the handle, if the button is not pressed when the door is opened in the room, the handle can only drive the handle connecting piece to idle when the handle is turned, and cannot drive the lock body connecting piece to rotate Therefore, even if a thief takes advantage of the loophole and uses a soft hook to stretch in from the cat's eye, and then catches the handle and rotates, the lock cannot be opened, thereby improving the safety of the lockset and meeting the higher requirements of the user.

Detailed ways

Referring to Fig. 1 to Fig. 4, the utility model discloses a cat's-eye anti-unlocking structure of an electronic lock, which includes a housing 1, which is provided with a handle connector 2 capable of rotating in the housing 1, and can be used for holding The lock body connector 3 that rotates in the hand connector 2, the lock body connector 3 is provided with a lock body connection hole 4, the handle connector 2 is provided with a handle connecting rod 5, and the handle rod 5 is A handle connection hole 6 is provided and a handle connecting rod 5 is fixedly connected with the handle. The handle connection hole 6 is provided with an insertion rod 7 that can slide therein and be inserted into the lock body connection hole 4. The insertion rod 7 There is a mounting hole 8 inside, and a return spring 9 is arranged in the mounting hole 8. One end of the return spring 9 is in contact with the bottom of the mounting hole 8, and the other end of the return spring 9 is in contact with the bottom of the connecting hole 4 of the lock body. Contact, the bottom of the handle connection hole 6 is provided with a through hole and a button rod 10 that can push the insertion rod 7 through the through hole, the button rod 10 is connected with the button on the handle, and the return spring 9 is a compression spring .

As shown in the figure, the handle connection hole 6 and the lock body connection hole 4 are regular hexagonal holes; the insertion rod 7 is a regular hexagonal rod that matches it, so when the insertion rod 7 is inserted into Only when the hand connecting hole 6 and the lock body connecting hole 4 can drive the above-mentioned two to rotate.

The principle of this structure is briefly described as follows: when it is necessary to open the door in the room, press the button first, and push the insertion rod 7 located in the handle connection hole 6 through the button, the insertion rod 7 compresses the return spring 9 and one end enters the lock body connector In the lock body connection hole 4 of 3, at this time, when the handle is turned, the handle will drive the insertion rod 7 through the handle connector 2, and the insertion rod 7 will drive the lock body connector 3 to rotate, and the lock body connector 3 is through the square Branch is connected with lock body, thereby lock body connector 3 drives lock body to unlock by square branch, after above-mentioned process, unclamps button, and plunger 7 can reset under the promotion of back-moving spring 9.

The anti-peephole unlocking structure of an electronic lock provided by the embodiment of the utility model has been introduced in detail above. In this paper, specific examples are used to illustrate the principle and implementation of the utility model. The description of the above embodiment is only used To help understand the method of the utility model and its core idea; at the same time, for those of ordinary skill in the art, according to the idea of the utility model, there will be changes in the specific implementation and scope of application. In summary, The contents of this specification should not be understood as limiting the utility model.
