Abstract

The utility model relates to a parallel link mechanism, which a comprises a lower rotor 1 connected with a handle of a front locking face, a left link 2, an upper rotor 3, a right link 4, and a square shaft 5 connected with an internal motion mechanism of a lock core, wherein the upper and the lower ends of the left link 2 are respectively connected with left ends of the upper rotor 3 and the lower rotor 1; the upper and the lower ends of the right link 4 are respectively connected with right ends of the upper rotor 3 and the lower rotor 1; the left link 2 and the right link 4 are mutually parallel, and can move following the lower rotor 1; the square shaft 5 is connected with the upper rotor 3, can rotate following the upper rotor 3 and can drive the internal mechanism of the lock core to move. The rotation of the handle can be transferred by the rotors, the parallel links and the square shaft to drive the internal mechanism of the lock core to move so that the operation of move transference between the handle and the internal mechanism of the lock core can be realized.

Description

Parallel linkage

Technical field

The utility model relates to a kind of component of lock, particularly a kind of driving mechanism of lock.

Background technique

At present, common door lock is directly to drive the motion of lock core internal mechanism by square shaft by handle on the market, and handle generally is placed on the neutral position of locking face.Along with the develop rapidly of fingerprint technique, fingerprint gate lock is also universal day by day, and the multifunctional fingerprint intelligent door lock more and more is subjected to people's favor; Door lock handle is placed the locking face below, and handle drives the motion of lock core internal mechanism by special driving mechanism, and the locking face top then has enough spaces to place fingerprint window and other function implement device.

Summary of the invention

The purpose of this utility model provides a kind of parallel linkage of realizing the motion of handle grip movable lock core internal mechanism, handle places the locking face lower position, the locking face top has enough spaces to place fingerprint window and other function implement device, and make product elegant in appearance, parallel linkage is simple in structure, cost of production is low, and is convenient and reliable.

In order to achieve the above object, the technical solution of the utility model is as follows:

A kind of parallel linkage comprises the lower rotor part 1 that is connected with preceding locking face handle, left connecting rod 2, upper rotor part 3, right connecting rod 4, the square shaft 5 that is connected with lock core internal motion mechanism; The upper and lower end of left side connecting rod 2 joins with the left end of upper rotor part 3, lower rotor part 1 respectively; The upper end of right connecting rod 4, lower end join with the right-hand member of upper rotor part 3, lower rotor part 1 respectively; A left side connecting rod 2, right connecting rod 4 are parallel to each other, can be with lower rotor part 1 motion; Square shaft 5 joins with upper rotor part 3, rotates and drive the motion of lock core internal mechanism with upper rotor part 3.

Owing to adopted said structure, the rotation of handle drives the motion of lock core internal mechanism by the transmission of rotor, parallel rod, square shaft, thereby realizes the operation of transmission of movement between handle and the lock core internal mechanism.

Embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail:

As shown in Figure 3, preceding locking face handle rotates up, and lower rotor part 1 counterclockwise rotates thereupon, and left connecting rod 2 moves downward simultaneously, and right connecting rod 4 moves upward, and promotes upper rotor part 3 rotation counterclockwise, and square shaft 5 rotates thereupon, thereby drives the motion of lock core internal mechanism.

As shown in Figure 4, preceding locking face handle is rotated down, and lower rotor part 1 clockwise direction thereupon rotates, and right connecting rod 4 moves downward simultaneously, and left connecting rod 2 moves upward, and promotes the rotation of upper rotor part 3 clockwise directions, and square shaft 5 rotates thereupon, thereby drives the motion of lock core internal mechanism.
