Abstract
The utility model relates to an electric switching mechanism for the plunger latch of an anti-theft door. The switching mechanism comprises a main motor frame for fixing a lifting motor; a screw is fixed on the output shaft of the lifting motor and connected with a plunger latch push-pull rod; the upper end of the main motor frame is in threaded connection with a transmission screw on the output shaft of a standby motor; the standby motor is fixed at the upper end of a standby motor frame; and the main motor frame and the standby motor frame are in slide fit vertically. The utility model overcomes the defect in the prior art that the common electric switching mechanism for the plunger latch of an anti-theft door has lower reliability, and in case of motor failure, the anti-theft door can not be opened or locked. By adopting the structural design, the mechanism with the standby motor greatly improves the working reliability of the electric switching mechanism for the plunger latch of an anti-theft door, and has the advantages of compact structure, flexible open and close, and long service life.
Description
Technical field
The utility model relates to a kind of security door lock bolt electric opening and closing mechanism.
Background technology
The lock bolt electric opening and closing mechanism of tradition security door, the advance and retreat of its lock bolt generally all have a motor to control, and are not difficult to find that if job failure appears in above-mentioned motor, security door just can not be opened, only by some destructive means.Certainly, destructive means bring the damage that can not repair also certainly will for the main body of security door, and user's loss is great.
Summary of the invention
For the reliability that overcomes common security door lock bolt electric opening and closing mechanism in the prior art lower, if job failure appears in motor, the problem of security door with regard to not opening, the utility model provides a kind of security door lock bolt electric opening and closing mechanism, the compact conformation of this security door lock bolt electric opening and closing mechanism, open and close flexibly, good reliability.
The technical scheme that its technical problem that solves the utility model adopts is: comprise the fixedly main motor frame of lifting motor, standing screw on the output shaft of lifting motor, screw rod interlock lock bolt pull bar, the upper end of the main motor frame drive screw on the standby motor output shaft that is threaded, standby motor is fixed on standby motor frame upper end, and main motor frame slides up and down with standby motor frame and cooperates.
Main motor frame is made of upper slide, lower skateboard and the connecting rod that is connected upper slide, lower skateboard, standby motor frame is made of standby motor mounting plate and the upper slide bar that is fixed on standby motor mounting plate lower end, lifting motor is fixed on the lower skateboard, the upper slide drive screw on the standby motor output shaft that is threaded, upper slide slides up and down with the upper slide bar of standby motor mounting plate lower end and cooperates, and standby motor is fixed on the standby motor mounting plate.
The lower end of drop shot links to each other with support, support is made of upper mounted plate, bottom plate and the drop shot that is connected upper mounted plate, bottom plate, drop shot and upper mounted plate are affixed, and the connecting rod and the upper mounted plate of main motor frame are slidingly matched, and lower skateboard and drop shot are slidingly matched.
Lock bolt pull bar and drop shot are slidingly matched.
The utility model has improved the reliability of security door lock bolt electric opening and closing mechanism work by above-mentioned specific design greatly in order to the structure with motor, has compact conformation, opens and closes advantage flexible, long service life.
