Description

Electronic lock spring bolt drive mechanism

Technical Field

The utility model relates to an electronic lock field especially relates to an electronic lock spring bolt drive mechanism.

Background

The transmission structure of the electronic lock spring bolt has a sauna lock spring bolt transmission structure, the sauna lock spring bolt transmission structure is through an electronic control stroke, the structure is high in production cost and occupies a larger space, the service life of the electronic lock spring bolt is greatly influenced by a circuit board, the humidity and dust can influence the normal use of the electronic lock spring bolt, and the problem of great practicability exists.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide an electronic lock spring bolt drive mechanism has that occupation space is little, the structure sets up simple, the stronger advantage of practicality.

In order to achieve the above purpose, the utility model can be realized by the following technical proposal:

a kind of electronic lock tongue drive motor constructs, including lock box, lock tongue, the said lock box sliding connection has the link fitting fixed with lock tongue, there are electrical machines in the said lock box, connect with the master gear on the output shaft of the said electrical machine, the said lock box has the link gear which links the slip of link fitting when the master gear rotates; the link gear includes pinion, pivot and spring, the pivot is rotated with the lock box and is connected, the pinion is fixed with the pivot and meshes with the master gear mutually, be provided with on the connecting piece and accomodate the groove, the pivot runs through accomodate groove and connecting piece sliding connection, the spring is located accomodate the inslot and around establishing in the pivot, accomodate groove one side and be provided with restriction spring pivoted spacing groove, the spring both ends are gone into the spacing inslot around going out the pivot back card, the length direction of spacing groove parallels with the axial of pivot, be fixed with the lug in the pivot, the lug card is gone into in the spring.

The utility model has the advantages that: the setting of spring is gone into to the lug card, not only can realize the effect that driving spring removed, and after the lug reached the stroke of spring completely, the lug can't continue to promote the spring to idle running plays the effect of protection to the motor through control stroke.

FIG. 1 is a detailed block diagram of an embodiment of the present invention;

fig. 2 is an internal structure diagram of the embodiment of the present invention.

Reference numerals: 1. a lock case; 2. a latch bolt; 3. a motor; 4. a connecting member; 6. a main gear; 7. a pinion gear; 8. a rotating shaft; 9. a spring; 10. a receiving groove; 11. a limiting groove; 12. and (4) a bump.

Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments:

a bolt transmission mechanism of an electronic lock is shown in figures 1 and 2 and comprises a lock box 1 and a bolt 2, wherein a connecting piece 4 fixed with the bolt 2 is connected in the lock box 1 in a sliding mode. A motor 3 is fixed in the lock box 1, a main gear 6 is fixed on an output shaft of the motor 3, and a linkage mechanism which links the connecting piece 4 to slide when the main gear 6 rotates is arranged in the lock box 1.

The linkage mechanism comprises a pinion 7, a rotating shaft 8 and a spring 9. Wherein, pivot 8 rotates with lock box 1 to be connected, pinion 7 is fixed with pivot 8 and meshes mutually with master gear 6, it accomodates groove 10 to have seted up on connecting piece 4, pivot 8 runs through accomodate groove 10 and connecting piece 4 sliding connection, spring 9 is located accomodate the inslot 10 and around establishing on pivot 8, be provided with restriction spring 9 pivoted spacing groove 11 in accomodating groove 10 one side simultaneously, spring 9 both ends are gone into spacing groove 11 around going out behind the pivot 8 card, the length direction of spacing groove 11 is parallel with the axial of pivot 8, be fixed with lug 12 on pivot 8, lug 12 card is gone into in spring 9.

Such structure setting, when motor 3 starts, motor 3's output shaft will drive master gear 6 and rotate, pinion 7 with master gear 6 engaged with this moment will synchronous rotation, the rotation of pinion 7 drives the synchronous rotation of lug 12 in the pivot 8 simultaneously, go into in spring 9 because of lug 12 card, pivoted lug 12 will oppress the rotatory silk at spring 9 this moment, impel spring 9 to the direction removal of keeping away from spring bolt 2, finally realize driving connecting piece 4 and the gliding effect of spring bolt 2, make in spring bolt 2 cunning lock box 1, so accomplish the spring bolt 2 retraction, the operation of unblanking is accomplished. When the electronic lock needs to be locked, the motor 3 only needs to be controlled to rotate reversely. The arrangement that the lug 12 is clamped into the spring 9 can not only realize the effect of driving the spring 9 to move, but also realize the effect that the lug 12 can not continuously push the spring 9 after the lug 12 completely reaches the stroke of the spring 9, so that the motor 3 can idle and be protected by controlling the stroke. Moreover, if motor 3 is at the in-process that starts, when spring bolt 2 is pressed by accident, because of the elastic setting of spring 9 itself, lug 12 still can rotate on spring 9, and even if spring bolt 2 is pressed by accident under the circumstances of normal unblock, can not influence drive mechanism's normal operating yet. The structure is simple in structure, small in occupied space and high in practicability.

Various other equivalent changes and modifications can be made by those skilled in the art according to the above technical solutions and concepts, and all such changes and modifications should fall within the protective scope of the present invention.
