Abstract
The utility model discloses a flexible energy-stored type dual gear on an electronic control lock, comprising a big gear meshed with a worm connected on a motor, a containing cavity is arranged on thebig gear, a left mounting groove and a right mounting groove are arranged in the containing cavity, the left and right ends of the left mounting groove and the right mounting groove are respectivelyprovided with springs, a mall gear meshed with a rack on a locking dog is arranged in the containing cavity, and convex ribs plugged in the left and right mounting grooves and arranged between the left and right springs are arranged on the small gear; in the design, dual gears are arranged in a splitting way, and the spring is arranged between the dual gears, the spring is adopted to prevent the rotating shaft of the motor to be locked after the locking dog has resistant force; meanwhile, displacement allowance is avoided after locking when the locking dog has resistant force, thereby improving the safety and being widely applied to the manufacturing of the electronic control lock.
Description
Technical field
The utility model relates to a kind of dual gear, particularly a kind ofly is used for the intelligent electric-controlled flexible energy storage type dual gear of locking.
Background technique
At present, electric control lock on the market normally is provided with the motor that is connected with control circuit in lock body, being connected with gear or worm and worm gear on the motor is meshed with tooth bar, be fixed with dead bolt on the tooth bar, but when dead bolt runs into excessive resistance in the process of motion, locking phenomenon appears in machine shaft, thereby causes damage of product easily.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of flexible energy storage type dual gear that is used on the electric control lock simple in structure, easy to use.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of flexible energy storage type dual gear that is used on the electric control lock, it comprise be connected motor on the gearwheel that is meshed of worm screw, described gearwheel is provided with holding cavity, be provided with left and right mounting groove in the holding cavity, the left and right two ends of left and right mounting groove are respectively arranged with spring, be equipped with in the described holding cavity with dead bolt on the tooth bar pinion in mesh, described small gear is provided with and is plugged in the left and right mounting groove, and the convex tendon between left and right spring.
The beneficial effects of the utility model are: this design designs the dual gear split, be provided with spring between it, after adopting spring to prevent that dead bolt from meeting obstructions, locking phenomenon appears in machine shaft, the locking back produces deflection yoke when having avoided dead bolt to meet obstructions simultaneously, improve Safety performance, thereby can be widely used in the making of electric control lock.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structure broken away view of the present utility model;
Fig. 2 is the structure broken away view of the utility model other direction.
Embodiment
With reference to Fig. 1, Fig. 2, a kind of flexible energy storage type dual gear that is used on the electric control lock, it comprise be connected motor on the gearwheel 1 that is meshed of worm screw, described gearwheel 1 is provided with holding cavity 11, be provided with left and right mounting groove 12,13 in the holding cavity 11, the left and right two ends of left and right mounting groove 12,13 are respectively arranged with spring 3, be equipped with in the described holding cavity 11 with dead bolt on tooth bar pinion in mesh 2, described small gear 2 is provided with and is plugged in the left and right mounting groove 12,13, and the convex tendon between left and right spring 3 21,22.
The working principle of this product is: when electric control lock is locked a door, motor moves forward by worm screw control tooth bar, thereby make dead bolt insert the effect that realization is locked a door automatically in the doorframe bayonet socket, in the process of locking a door, when if dead bolt runs into excessive resistance, tooth bar will be controlled small gear 2 stop motions, motor still is in rotary state, thereby rotatory force is delivered on the gearwheel 1, gearwheel 1 is rotated and pressure spring 3, after the resistance of dead bolt is removed, under the pressure of spring 3, will control small gear 2 and dead bolt be inserted the doorframe bayonet socket fully by tooth bar, this design is provided with spring 3 with dual gear split design between it, after employing spring 3 prevents that dead bolt from meeting obstructions, locking phenomenon appears in machine shaft, the locking back produces deflection yoke when having avoided dead bolt to meet obstructions simultaneously, improves Safety performance, thereby can be widely used in the making of electric control lock.
