The double-spring door lock bearing base is reasonable in structure, stable and smooth in work, improves use experience of users and prolongs service life.
Description
Technical field
The utility model relates to a kind of door lock bearing seat structure.
Background technology
The door lock bearing base is fixed on the door, provide a power that resets to door lock handle, so that twisting, door lock handle can automatically go back to original position after unclamping, door lock bearing base inside now is provided with the spring resettlement groove that the moving axis center circle arc that rotates arranges, a back-moving spring is housed in the spring resettlement groove, with be provided with the protruding post that cooperates with back-moving spring on the rotatable cover that base cooperates, door lock handle connection side core, square core connection of rotating lid.In the time of the rotary door lock handle, drive rotatable cover and rotate, protruding post compresses back-moving spring, unclamp door lock handle after, back-moving spring promotes rotatable cover and resets, and resets thereby drive door lock handle.
But the bearing base work of this single back-moving spring is often stable not, provides opposition often to have retardance by a spring that is placed in the circular arc spring resettlement groove, so that the door lock handle card pauses, noise is arranged, and handle rotates smooth not; In addition the application life of single back-moving spring short, through long-time rotary door lock handle repeatedly, the easy fatigue failure of the back-moving spring in the spring resettlement groove causes the rotary door lock handle to reset smoothly, has affected user's experience; Because the integrated level of door lock handle is higher, need special instrument to carry out installing/dismounting, the inefficacy of a back-moving spring often needs whole door lock is changed, and has increased cost, has caused unnecessary waste.
The utility model content
For the door lock bearing base work that overcomes prior art stable not, the deficiency that application life is short, the utility model provides a kind of working stability smooth, the dual spring door lock bearing base of long service life.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of dual spring door lock bearing base, comprise the base that is provided with through hole, and rotatably be installed in rotatable cover on the base, described rotatable cover comprises the rotation axial region that is socketed in the through hole and the auxiliary section that cooperates promotion to reset with base, the center of described rotatable cover is provided with the mating holes that passes for handle Fang Xin, be provided with two isocentric circular arc spring resettlement grooves on the fitting face of described base and rotatable cover, be mounted with back-moving spring in the described spring resettlement groove, described rotatable cover rotates around the center of circle of spring resettlement groove, and the auxiliary section of described rotatable cover is provided with two and inserts respectively the protruding post that compresses corresponding back-moving spring in the corresponding spring resettlement groove along with the rotation around the center of circle.
As improvement of the technical scheme, described two spring resettlement groove in the same sizes, relatively described centre point is symmetrical, two protruding post in the same sizes of described rotatable cover, relatively described centre point is symmetrical.
As further improvement in the technical proposal, the length of the spring resettlement groove of described base slightly is longer than the drift under the back-moving spring installment state, behind the back-moving spring of packing into, forms a space that holds protruding post.
In order to make the rotation between rotatable cover and the base more smooth stable, be installed with bearing between the rotation axial region of described rotatable cover and the base.
The beneficial effects of the utility model are: be provided with two back-moving springs, parallel reverse reset response power is provided, structure is more reasonable, and more stable work, smoothness have been improved user's experience, have prolonged the application life of door lock bearing base.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is STRUCTURE DECOMPOSITION schematic diagram of the present utility model;
Fig. 2 is the structural representation of the utility model rotatable cover.
The specific embodiment
See figures.1.and.2, a kind of dual spring door lock bearing base of the present utility model, comprise the base 1 that is provided with through hole 11, and rotatably be installed in rotatable cover 2 on the base 1, described rotatable cover 2 comprises the rotation axial region 21 that is socketed in the through hole 11 and the auxiliary section 22 that cooperates promotion to reset with base 1, the center of described rotatable cover 2 is provided with the mating holes 23 that passes for handle Fang Xin, be provided with two isocentric circular arc spring resettlement grooves 12 on the fitting face of described base 1 and rotatable cover 2, be mounted with back-moving spring 13 in the described spring resettlement groove 12, described rotatable cover 2 rotates around the center of circle of spring resettlement groove 12, and the auxiliary section 22 of described rotatable cover 2 is provided with two and inserts respectively the protruding post 221 that compresses corresponding back-moving spring 13 in the corresponding spring resettlement groove 12 along with the rotation around the center of circle.
In this specific embodiment, base 1 roughly is the hollow circular ring shape, comprise metal outer frame frame and the counterpart that is installed on the metal outer frame frame, be provided with two on the metal outer frame frame for the fixing hole 14 that is connected and fixed, be the through hole 11 that cooperates with the rotation axial region 21 of rotatable cover 2 in the middle of the counterpart, in order to make the rotation between rotatable cover 2 and the base 1 more smooth stable, be installed with bearing 3 between the rotation axial region 21 of described rotatable cover 2 and the base 1, will also tightly be snapped together between base 1 and the rotatable cover 2 when rotating axial region 21 and bearing 3 chucking.
Circular arc spring resettlement groove 12 is arranged on the side that counterpart cooperates with rotatable cover 2, two spring resettlement groove 12 in the same sizes, relatively described centre point is symmetrical, two protruding post 221 in the same sizes of described rotatable cover 2, relatively described centre point is symmetrical, the length of the spring resettlement groove 12 of described base 1 slightly is longer than the drift under back-moving spring 13 installment states, behind the back-moving spring 13 of packing into, forms a space that holds protruding post 221.
