Abstract
Provided is a tension sensing unlocking system. The tension sensing unlocking system is characterized by comprising a sensing lock, a gear and a sensor circuit, the sensing lock is connected with the gear, the gear is connected with the sensor circuit through a metal wire, the sensor circuit is connected with a power source, a switch, an indicator lamp and an electromagnet in series in sequence, the sensor circuit is further connected with a metal strip in parallel, the metal strip is connected through a spring, a rack is arranged on the top of the metal strip, and the tail end of the rack is arranged under the gear. The tension sensing unlocking system is simple in structure, convenient to use and low in cost, has high market economic benefit, and is worth popularizing.
Description
Technical field
The utility model belongs to induction lock release field, is specifically related to a kind of pulling force induction system for unlocking.
Background technology
Along with the raising day by day of people's life, people also more and more pay attention to life, are all provided with lock everywhere to ensure the safety of life and property in life.Therefore various locks also just appear at people's sight line, from before general iron lock, copper be locked into the normal induction lock using of present people.But the system architecture of the gravity sensing using in the market lock is all very complicated, and cost is also high, use also inconvenience, in use bring many problems to people.
Utility model content
The utility model provides a kind of and uses simply, and cost is low, the pulling force induction system for unlocking that accuracy is high.
A kind of pulling force induction system for unlocking, is characterized in that: comprise induction lock, gear and sensor circuit; Described induction lock is connected with gear; Described gear is connected with sensor circuit by wire; Described sensor circuit is in series with power supply, switch, indicator lamp and electromagnet successively, and with the bonding jumper being connected by spring in addition of sensor circuit parallel connection, this bonding jumper top is provided with the tooth bar engaging with gear, and tooth bar end is engaged under gear.
According to a kind of pulling force induction system for unlocking described in the utility model, it is characterized in that: on described sensor circuit, be also in series with pressure password display, can conveniently clearly show the power that section release is any time used.
According to a kind of pulling force induction system for unlocking described in the utility model, it is characterized in that: described indicator lamp is LED lamp to remind clearly people when to start release, release when finished.
The beneficial effects of the utility model are: simple in structure, easy to use, with low cost.
Brief description of the drawings
1-pressure password display in figure, 2-spring, 3-bonding jumper, 4-induction lock, 5-gear, 6-electromagnet, 7-indicator lamp, 8-wire, 9-power supply, 10-switch, 11-tooth bar.
Detailed description of the invention
As shown in Figure 1, a kind of pulling force induction system for unlocking, comprises induction lock 4, gear 5 and sensor circuit; Described induction lock 4 is connected with gear 5; Described gear 5 is connected with sensor circuit by wire 8; Described sensor circuit is in series with power supply 9, switch 10, indicator lamp 7 and electromagnet 6 successively, the bonding jumper 3 being connected by spring 2 in addition with sensor circuit parallel connection, these bonding jumper 3 tops are provided with the tooth bar 11 engaging with gear, and gear 5 ends are engaged under gear 5; On described sensor circuit, be also in series with pressure password display 1, can conveniently clearly show the power that section release is any time used; Described indicator lamp 7 is LED lamp, can remind clearly people when to start release, when finishes release.
In use, only need be by power connection, closing switch, now whole sensor circuit energising, electromagnet produces magnetic, attracts the bonding jumper in parallel with sensor circuit, bonding jumper is under the drive of electromagnet, attract toward electromagnet direction, with bonding jumper on tooth bar meshed gears toward the opposite direction motion of bonding jumper motion, thereby the induction lock being connected with gear is under the effect of gear pulling force and open; After finishing using, only power switch need be closed, last electromagnet loses magnetism, and bonding jumper is got back to original position, once responds to release thereby complete.
