Abstract
The utility model discloses an anti -sticking mechanism, including mounting base, motor support fixed plate, motor support fixed plate is fixed to be set up in the mounting base, still including the reversal short circuit switch fixing plate, reversal short circuiting switch, driving motor backup pad and the driving motor that set up at the mounting base, reversal short circuit switch fixing plate's one end fixed connection is on motor support fixed plate, and reversal short circuiting switch fixed connection is on reversal short circuit switch fixing plate's the other end, the one corner of driving motor backup pad articulates on reversal short circuit switch fixing plate, when the locking lever was being carried out the blocking order and is run into the barrier, driving motor's output gear and transmission rack be unable the rotation all, and the driving motor atress moves left, and then the driving motor backup pad is pressed on the contact of reversal short circuiting switch the one corner in two jiaos in addition for the conversion of driving motor electrode, driving motor output shaft counter -clockwise turning has been avoided being blocked because of the locking lever at the shutting in -process, and has been damaged driving motor's condition emergence.
Description
Technical field
The utility model relates to a kind of lock, particularly relates to a kind of clamp-proof mechanism.
Background technology
Current theftproof lock in use often runs into jammed situation, and when occurring that locking bar is stuck, motor is easily because output shaft is stuck thus impaired, and for above situation, current to prevent jammed device from arranging all very complicated, execution not easy to operate.
Utility model content
For weak point of the prior art, the utility model provides a kind of simple clamp-proof mechanism, for theftproof lock, prevents from blocking and then by motor damage because of motor output shaft.
In order to solve the problems of the technologies described above, the utility model have employed following technical scheme:
A kind of clamp-proof mechanism, comprises the reversion short switch fixed head be arranged in mounting base, electric machine support fixed head, reversion short switch, securing rod, drive motors gripper shoe and drive motors; Described reversion short switch fixed head is L-type structure, and one end of reversion short switch fixed head is fixedly connected on electric machine support fixed head, and described reversion short switch is fixedly connected on the other end of reversion short switch fixed head; Described drive motors gripper shoe is gusseted plate, and one jiao of described drive motors gripper shoe is hinged on reversion short switch fixed head; One jiao in another two jiaos of described drive motors gripper shoe corresponding with the contact of reversion short switch.
Further, described securing rod is arc-shaped structure, securing rod edge arranges driving rack, the gears meshing that the output shaft of described driving rack and drive motors is installed, securing rod arranges along the edge of the circular arc low groove of mounting base and can be driven along the slip of circular arc low groove by drive motors, and described reversion short switch, drive motors and serial battery are connected on wire.
Compared with prior art, the utility model tool has the following advantages:
When securing rod is when performing blocking order and running into obstruction, one end of securing rod is stuck, the output gear of drive motors and driving rack all cannot rotate, drive motors is stressed to be moved to the left, and then in another two jiaos of drive motors gripper shoe one jiao is pressed on the contact of reversion short switch, drive motors electrode is changed, drive motors output shaft is rotated counterclockwise, when after arrival assigned address, motor stops, with obstruction being removed, avoid because securing rod is stuck in latching process, and then the situation damaging drive motors occurs.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of clamp-proof mechanism, comprise mounting base 1, be arranged on the electric machine support fixed head 2 in mounting base 1, reversion short switch fixed head 6, reversion short switch 7, drive motors gripper shoe 4, securing rod 10 and drive motors 5, reversion short switch fixed head 6 is L-type structure, one end of reversion short switch fixed head 6 is fixedly connected on electric machine support fixed head 2, and reversion short switch 7 is fixedly connected on the other end of reversion short switch fixed head 6.Drive motors gripper shoe 4 is gusseted plate, and one jiao of drive motors gripper shoe 4 is hinged on reversion short switch fixed head 6.One jiao in another two jiaos of drive motors gripper shoe 4 corresponding with the contact of reversion short switch 7.When securing rod is blocked by obstruction, the upper of the contact of reversion short switch 7 can be pressed in during drive motors gripper shoe 4 Forced rotation, drive motors 4 is reversely rotated, avoid and damage drive motors 5.
Securing rod 10 is arc-shaped structure, locking bar 10 edge arranges driving rack 10-1, the gears meshing that the output shaft of driving rack 10-1 and drive motors 5 is installed, securing rod 10 arranges along the edge of the circular arc low groove of mounting base 1 and can drive along the slip of circular arc low groove by drive motors 5, and reversion short switch 7, drive motors 5 and serial battery are connected on wire.The motion driving securing rod 10 is coordinated, the function completing locking and unblank by the gear on the output shaft of driving rack 10-1 and drive motors 5.
When securing rod is when performing blocking order and running into obstruction, one end of securing rod 10 is stuck, output gear and the driving rack 10-1 of drive motors 5 all cannot rotate, drive motors 5 is stressed to be moved to the left, and then in another two jiaos of drive motors gripper shoe one jiao is pressed on the contact of reversion short switch 7, drive motors 5 electrode is changed, drive motors 5 output shaft is rotated counterclockwise, when after arrival assigned address, drive motors 5 stops with obstruction being removed, avoid because securing rod is stuck in latching process, and the situation damaging drive motors occurs.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
