Abstract

Door lock resetting transmission mechanism comprising: a handle module (1), a lock face (2), a resetting module (3), and a clutch (4). The lock face is provided thereon with a positioning rod (21), and the resetting module is sleeved on the positioning rod. The resetting module and the handle module are engagingly connected via gears. The handle module and the clutch are concentrically assembled and are allowed to rotate around a same central axis. The door lock resetting transmission mechanism employs the principle of torsion springs, streamlines parts, and reduces the size of the mechanism.

Description

Door lock reset transmission mechanism

Technical field

The utility model relates to a door lock, in particular to a door lock reset transmission mechanism, in particular to a reset transmission mechanism inside a door lock.

Background technique

At present, there are various types of door locks on the market, and the mechanical transmission methods of the door locks are also various, and the types of reset structures of the handles are also more and more, and most of the positioning structures are selected from the structural features of the springs, such as the springs and the springs. The tension spring; wherein the vortex spring is generally annular, the center of the torsion of the vortex spring is utilized to achieve the positioning of the handle.

technical problem

Technical solution

The purpose of the utility model is to provide a novel door lock reset transmission mechanism, adopting the principle of the spring spring, newly designing the parts structure matched with the vortex spring, and utilizing the characteristics of the components themselves to achieve more ideal technical effects, and the market Compared with the door lock reset transmission mechanism, it has the characteristics of streamlined parts, cost saving, volume reduction, convenient assembly and low production cost.

In order to achieve the above object, the technical solution of the present invention is as follows:

A door lock reset transmission mechanism, comprising: a handle module 1, a lock surface 2, a reset module 3, a clutch 4; The lock surface 2 has a positioning post 21, and the reset module 3 is fitted on the positioning post 21; the reset module 3 and the handle module 1 are connected by gear engagement; the handle module 1 and the clutch 4 are concentrically assembled and rotatable about the same central axis.

The handle module 1 and the clutch 4 are concentrically mounted on the lock surface 2 so as to be rotatable about the same central axis.

The handle module 1 includes a handle 11 and a rotating ring 12, and the handle 11 is fixedly coupled with the rotating ring 12; the rotating ring 12 can also be fixed to the handle 11 by a screw connection;

The rotating ring 12 has a rib 121, and the clutch 4 has a stopper 41. The stopper 41 abuts against the rib 121. The clutch 4 and the rotating ring 12 are concentrically assembled, and the two can drive each other.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiments of the invention

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

1 , 2, and 3 show the positional relationship of the components, the handle 11 and the rotating ring 12 are fastened together; the reset module 3 is composed of an upper reset block 31, a lower reset block 32, and a reset coil spring. 33, the lock surface 2 has a positioning post 21, the lower reset block 32 of the reset module 3 is set on the positioning post 21, and the reset scroll spring 33 is set on the lower reset block 32, and the two can be rotated around the positioning post 21; There is a first flange 311 on the lower return block 32, and a second flange 321 on the lower reset block 32. The first flange 311 and the second flange 321 are concentrically assembled. In the original state, both sides of the reset coil spring 33 are simultaneously mounted on the same. Both sides of the first flange 311 and the second flange 321 , in the moving state, the second flange 321 drives the reset coil spring 33 to rotate relative to the first flange 311 around the positioning post 21; the upper reset block 31 is fixed on the lock surface 2, the relative lock surface 2 is always stationary; the rotating ring 12 has a rib 121, the clutch 4 has a stop 41, and the stop 41 abuts the rib 121; the lower return block 32 and the rotating ring 12 have a toothed structure, and the two pass The gear meshes drive each other.

As shown in FIG. 4, the movement relationship between the reset module 3 and the rotating ring 12 and the clutch 4 is specifically shown in a stationary state; when the handle module 1 is rotated clockwise by an external force, due to the rib 121 on the rotating ring 12 and the clutch 4 The stopper 41 abuts, so the clutch 4 rotates clockwise with the handle module 1 to achieve the purpose of outputting the handle torque; at the same time, when the handle module 1 rotates clockwise, the gear on the rotating ring 12 drives the lower reset block 32 through the gear meshing. The counterclockwise rotation is performed, since the upper reset block 31 is fixed on the lock surface 2 and cannot be rotated, and the side of the reset coil spring 33 is again fitted to the second flange 311 of the upper reset block 31 and the second convex portion of the lower reset block 32. On the edge 321, when the lower reset block 32 rotates together with the handle module 1, only one side of the reset coil spring 33 can be rotated together, so that the reset coil spring 33 generates a restoring force, as shown in FIG. 5; when coming from the handle module 1 When the external force disappears, the restoring force of the returning vortex spring 33 forces the lower returning block 32 to rotate clockwise to reverse the rotation of the handle module 1 counterclockwise for resetting purposes.

Similarly, when the handle 1 is rotated counterclockwise by an external force, since the rotating ring 12 and the clutch 4 do not collide, the rotating ring 12 cannot rotate the clutch 4 together, and the handle torque cannot be output, but the mutual driving between the reset module 3 and the rotating ring 12 is The principle is the same, and the resetting effect generated by the handle module 1 is the same, that is, the reset module 3 can reset the handle regardless of the rotation of the handle.
