Problems solved by technology

Electronic locks such as fingerprint locks, combination locks, card swiping locks, etc. are mostly used on the market now to improve the convenience of use; That is, the handle will not rotate idly. At this time, the handle can be rotated by using pliers to forcefully twist the handle to drive the dial of the lock cylinder to rotate, thereby realizing violent unlocking. Therefore, the existing lock has the problem that it cannot be unlocked by explosion-proof force, and the safety factor is lower

Embodiment approach 1

[0039] Embodiment 1: The cross section of the linkage hole 100 is a polygon, such as a square, a rectangle, etc. Correspondingly, the cross section of the first linkage rod 31 is a polygon that matches the linkage hole 100;

Embodiment approach 2

[0040] Embodiment 2: a block protrudes from the first linkage rod 31, and a slot for inserting the block is provided on the linkage hole 100, so that when the first linkage rod 31 rotates with the handle 10, the block pushes the slot The groove wall, so as to link the transmission member 20; Embodiment 3: as Figure 5-6 As shown, the linkage hole 100 is arranged eccentrically with the handle 10, that is, the central axis of the linkage hole 100 is staggered from the central axis of the handle 10; more specifically, the linkage hole 100 is a round hole, and the first linkage rod 31 is cylindrical; The third preferred embodiment of the present invention is easier to process.

[0041] The above-mentioned rotating part 321 can be an existing lock cylinder. In the present invention, the rotating part 321 is preferably the output shaft of the motor 32, and the body of the motor 32 is installed on the handle 10. In this way, the handle 10 can only be realized by controlling the motor...

Abstract

The invention discloses a lock linkage structure which comprises a driving part, a handle and a first linkage mechanism; a linkage hole is formed in the driving part; the handle and the driving part can relatively rotate; the first linkage mechanism comprises a first linkage rod, a rotary piece and a first reset elastic piece; the first linkage rod is fixed with the handle in the circumferential direction to rotate along with the handle so as to be aligned with the linkage hole; the first linkage rod can move in the axial direction relative to the handle and can be inserted in or separated from the aligned linkage hole; the rotary piece is in transmission joint with the first linkage rod; when the rotary piece moves towards a first direction, the rotary piece can be linked with the first linkage rod to be separated from the linkage hole and prevents the first linkage rod from moving in the direction close to the linkage hole; when the rotary piece moves towards a second direction, therotary piece removes stop to the first linkage rod; and the first reset elastic piece is used for providing the elastic stress enabling the first linkage rod to be inserted in the linkage hole. The lock linkage structure can prevent violent unlocking and can increase the security coefficient. The invention further discloses a lock.

Description

technical field [0001] The invention relates to the field of locks, in particular to a lock linkage structure and a lock. Background technique [0002] From ancient times to the present, locks have always been a necessity in people's lives. Almost every house has a lock, which is related to the life and property safety of the whole family. [0003] However, with the continuous development of human society and technology, locks are also slowly changing. Electronic locks such as fingerprint locks, combination locks, card swiping locks, etc. are mostly used on the market now to improve the convenience of use; That is, the handle will not rotate idly. At this time, the handle can be rotated by using pliers to forcefully twist the handle to drive the dial of the lock cylinder to rotate, thereby realizing violent unlocking. Therefore, the existing lock has the problem that it cannot be unlocked by explosion-proof force, and the safety factor is lower. Contents of the invention...
