The utility model designs a shifting block driving type fingerprint safe keeping box door lock mechanism which is mainly driven by a torsion spring, aiming at solving the problems existing in the door lock mechanism of a ratchet wheel pawl structure used for the prior fingerprint safe keeping box that the structure is complex, the volume is large, and the installation and the maintenance are inconvenient. The utility model comprises a motor (1), a lock bracket (2), a lock catch (3) and a lock tongue (4), wherein the motor (1) is installed on one side of the lock bracket (2), and the lock catch (3) is installed on the box door of the safe keeping box and is opposite to a lock tongue (4). The utility model is characterized in that the lock tongue (4) is pivoted on the pivot shaft (5) on the lock bracket (2), a wrist (6) is arranged at one end of the lock tongue (4) opposite to the lock catch (3), a lock tongue torsion spring (7) is sleeved on the pivot shaft (5), one end of the lock tongue torsion spring (7) is propped against the wrist (6), the other end is propped against one end of the lock tongue torsion spring (8) penetrating through the lock bracket (2), a shifting block (9) is installed on the output shaft of the motor (1), and one end of the lock tongue torsion spring (8) penetrating through the lock bracket (2) is propped against the shifting block (9). The utility model has the advantages that the structure is simple, the volume is small, the service life is long, and the action is reliable.

Description

Shifting Block Driven Gate Lock Mechanism Of Fingerprint Safety-deposit Box

Technical field

The utility model relates to door lock mechanism, the door lock mechanism that uses on especially a kind of fingerprint safety-deposit box, specifically a kind of Shifting Block Driven Gate Lock Mechanism Of Fingerprint Safety-deposit Box.

Background technology

At present, the lock structure of fingerprint safety-deposit box generally adopts the mode of motor-driven ratchet mechanism to realize auto-unlocking.Because ratchet mechanism is comparatively complicated, processing, installation, maintenance are all inconvenient, and its volume is also bigger simultaneously, has taken the usefull space in the bigger safe deposit box.For this reason, the applicant has carried out deep research, and with applied for relevant utility model patent in 2006, as shown in Figure 1, but find in actual use, because the technical scheme that adopts motor band drag-line to drive, because the drag-line perseveration is easy to produce tired face and damages in advance, influenced the normal operation of safe deposit box, only be about 2000 times general application life, and simultaneously, motor must adopt more powerful motor in order to drive drag-line, influence the application life of battery, so this situation is necessary further to be improved.

Summary of the invention

The purpose of this utility model is at the problem that complex structure, volume are big, installation, maintenance is inconvenient and the life-span is short of the door lock mechanism existence of the click structure of existing fingerprint safety-deposit box use, designs a kind of Shifting Block Driven Gate Lock Mechanism Of Fingerprint Safety-deposit Box based on the torsion spring driving.

The technical solution of the utility model is:

A kind of Shifting Block Driven Gate Lock Mechanism Of Fingerprint Safety-deposit Box, comprise motor 1, lock frame 2, snap close 3, dead bolt 4, motor 1 is installed in a side of lock frame 2, snap close 3 is installed on the safe deposit box chamber door and is relative with dead bolt 4, it is characterized in that described dead bolt 4 is journaled on the pivot of locking on the frame 25, on the relative end of dead bolt 4 and snap close 3, be provided with bearing pin 6, on pivot 5, be set with dead bolt torsion spring 7, one end and the bearing pin 6 of dead bolt torsion spring 7 offset, the other end offsets with an end of the dead bolt torsion spring 8 that passes lock frame 2, shifting block 9 is installed on the output shaft of motor 1, and the end and this shifting block 9 that pass the dead bolt torsion spring 8 of lock frame 2 offset.

An end that is provided with on lock frame 2 for dead bolt torsion spring 8 interted and mobile therein waist through hole 10.

The utlity model has following advantage:

1, the utility model has saved traditional ratchet mechanism, makes the torsion spring of dead bolt location can realize opening the door automatically by the motor pulling, and structure is very simple.

2, dwindle overall dimensions greatly, helped enlarging the safe deposit box inner space.

3, processing, installation simply can reduce processing and installation cost greatly.

4, purposes is wide, not only can be used for safe deposit box, also can be used for the occasion of other automatically controlled strongbox, cabinet and all use Fingerprint Lock.

5, shifting block long service life of the present utility model, little power consumption, no-failure operation for a long time.

Description of drawings

Fig. 1 is the structural representation of existing drag-line drive-type door lock mechanism.

Fig. 2 is a structural representation of the present utility model.

Fig. 3 is that the A of Fig. 2 is to view.

The specific embodiment

Following structure drawings and Examples are further described the utility model.

Shown in Fig. 2,3.

A kind of Shifting Block Driven Gate Lock Mechanism Of Fingerprint Safety-deposit Box, comprise motor 1, lock frame 2, snap close 3 and dead bolt 4, as shown in Figure 2, motor 1 is installed in a side of lock frame 2, snap close 3 is installed on the safe deposit box chamber door and is relative with dead bolt 4, dead bolt 4 is journaled on the pivot 5 that passes lock frame 2, and be arranged in the lock frame 2, dead bolt 4 is provided with a breach that offsets with dead bolt torsion spring 8, on the relative end of dead bolt 4 and snap close 3, be provided with bearing pin 6, dead bolt torsion spring 7 is sleeved on the pivot 5, as shown in Figure 3, its end and bearing pin 6 offset, so that dead bolt 4 produces a torsion of opening all the time, the other end offsets with an end of the dead bolt torsion spring 8 that passes lock frame 2, this dead bolt torsion spring 8 is installed in the safe deposit box housing, and offsets with the safe deposit box housing, is provided with a waist through hole 10 that dead bolt torsion spring 8 is moved on lock frame 2, shifting block 9 on the external part of dead bolt torsion spring 8 and motor 1 output shaft offsets, and is moving forward and backward in waist through hole 10 under the drive of shifting block 9.

The course of work of the present utility model is:

In the time can opening the keeping chamber door through checking, motor 1 rotates under the instruction control of electric-control system, shifting block 9 on the motor output shaft drives the dead bolt torsion spring 8 that offsets with it and moves in waist through hole 10, an end that originally also is pressed in the dead bolt 4 on this dead bolt torsion spring 8 this moment breaks away from, this moment, dead bolt 4 rotated under the effect of dead bolt torsion spring 7, script is separated with the other end and the snap close 3 of the dead bolt 4 that snap close 3 is interlocked, and promptly finishes the process of unblanking.

At closing time, external force promotes snap close 3, and snap close 3 promotes the active force rotation that dead bolt 4 overcomes dead bolt torsion spring 7, and at this moment, the other end of dead bolt 4 turns to the top of dead bolt torsion spring 8, and snap close 3 also is interlocked with dead bolt 4 simultaneously.

It is all same as the prior art that the utility model does not relate to part.
