Abstract
The utility model relates to an anti-theft lock, which is composed of a power supply, a switch, a starter, an alarm device, a high voltage module, a connecting rod and a lock. The high voltage module [1] and the alarm device [2] are connected in parallel and are formed into an anti-theft branch, the branch is connected in series with the power supply E, the switch K, the starter [3], the connecting rod [4] and a keyhole [5], one end of the connecting rod is inserted into the keyhole [5] from the backside of the lock, and the other end of the connecting rod is connected with the starter [3]. When a key is inserted into the keyhole [5] of the lock, the connecting rod [4] is pushed, a circuit is switched on, the high voltage is released by the high voltage module [1], and the alarm device [2] generates the alarm and has the function of preventing the theft.
Description
The utility model relates to a kind of lock, particularly a kind of theftproof lock of circuit control.
All kinds of theftproof locks on the market mainly are by mechanical device at present, the difficulty when increasing the thief picking lock, thus play antitheft effect, but this class theftproof lock or cost height or anti-theft effect are not good enough.
The purpose of this utility model is to provide that a kind of cost is low, the theftproof lock by circuit control of good anti-theft effect.
The utility model is finished like this, high-pressure modular and alert exhale device to be connected in parallel to constitute antitheft branch road, one end of connecting rod inserts keyhole from the back side of locking son, and the other end connects starter, and power supply, switch, starter, connecting rod, keyhole and antitheft branch road are connected in series and constitute the loop.
Also has a kind of theftproof lock, it exhales device to be connected in series successively by power supply, switch, starter, police, one end of connecting rod is connected with the keyhole of lock, the other end is connected with starter, starter is made of isolation baffle plate, three springs, pistons, and the spring in centre position abuts against on the piston, and two springs on both sides connect respectively from switch comes and from alert lead of exhaling device to come, piston is provided with two contacts, and two springs with the plate washer both sides are corresponding respectively.
The utility model is described in further detail now to reach enforcement one example in conjunction with the accompanying drawings.
Fig. 1 is the utility model schematic diagram.
As shown in Figure 1, high-pressure modular ［ 1 ］ and alert exhale device ［ 2 ］ to be connected in parallel to constitute antitheft branch road, one end of connecting rod ［ 4 ］ connects the keyhole ［ 5 ］ of lock, the other end connects starter ［ 3 ］, and power supply E, K switch, starter ［ 3 ］, connecting rod ［ 4 ］, keyhole ［ 5 ］ and the series connection of antitheft branch road constitute the loop.Starter ［ 3 ］ is made of isolation baffle plate ［ 6 ］, spring ［ 7 ］ ［ 8 ］ ［ 9 ］ and piston ［ 10 ］, isolation baffle plate ［ 6 ］ is provided with three springs ［ 7 ］ ［ 8 ］ ［ 9 ］, middle springs ［ 9 ］ abuts against on the connecting rod ［ 4 ］, two springs ［ 7 ］ ［ 8 ］ on both sides are connected from K switch with from alert lead of exhaling device ［ 2 ］ to come, piston ［ 10 ］ is provided with two contacts ［ 11 ］, and is corresponding with two springs ［ 7 ］ ［ 8 ］ on isolation baffle plate ［ 6 ］ both sides respectively.
Connect K switch during use, during thief's picking lock, key must move ahead along keyhole ［ 5 ］, promote connecting rod ［ 4 ］, connecting rod ［ 4 ］ promotes piston ［ 10 ］, thereby two contacts ［ 11 ］ on the piston ［ 10 ］ are contacted with spring ［ 7 ］ ［ 8 ］, at this moment, circuit is connected high-pressure modular and is discharged high pressure, and the alert device ［ 2 ］ of exhaling is reported to the police, thereby plays antitheft effect.
Also has a kind of theftproof lock, it is by power supply E, K switch, starter ［ 3 ］, the police exhales device ［ 2 ］ to be connected in series successively, one end of connecting rod ［ 4 ］ inserts keyhole ［ 5 ］ from the back side, the other end is connected with starter ［ 3 ］, starter ［ 3 ］ is by isolation baffle plate ［ 6 ］, three springs ［ 7 ］ ［ 8 ］ ［ 9 ］, piston ［ 10 ］ constitutes, isolation baffle plate ［ 6 ］ is provided with three springs ［ 7 ］ ［ 8 ］ ［ 9 ］, middle springs ［ 9 ］ abuts against on the piston ［ 10 ］, two springs ［ 7 ］ ［ 8 ］ on both sides are connected from K switch with from alert lead of exhaling device ［ 2 ］ to come, piston ［ 10 ］ is provided with two contacts ［ 11 ］, and is corresponding with two springs ［ 7 ］ ［ 8 ］ on isolation baffle plate ［ 6 ］ both sides respectively.
