Description
Technical field
The utility model relates to a kind of lockset, particularly a kind of Dual-safety lock.
Background technology
Bicycle is the good vehicles of a kind of conventional convenience, people are stolen to prevent bicycle, usually all can be pinned with lockset, but existing lockset is easy to be opened by the special tool of robber, therefore anti-theft capability is poor, can not guarantee the safety of bicycle.
Summary of the invention
Problem to be solved in the utility model is: provide a kind of structure simple, there is the warning function Dual-safety lock that thus anti-theft capability is strong.
In order to solve the problem, Dual-safety lock of the present utility model, comprise manual lock, dc source, electromagnetic lock, warning device and protective resistance, the first contact is provided with in described manual lock, second contact and the 3rd contact, keyhole is provided with in described manual lock, groove is provided with in described keyhole, the top of keyhole is fixed in described first contact, the bottom of keyhole is fixed in described second contact, described 3rd contact is fixed in groove, described electromagnetic lock is serially connected with between the positive pole of dc source and negative pole, described first contact is connected with the positive pole of dc source, be connected with the negative pole of dc source again after described second contact is connected in series with warning device, described 3rd contact is connected with the negative pole of dc source after connecting with protective resistance again, described first contact and the 3rd contact are triggered by the key matched with manual lock.
Further, in order to can insert key at manual lock state under fast electromagnetic lock is locked, Dual-safety lock of the present utility model, is also in series with a hand switch between described protective resistance and the negative pole of dc source.
Further, Dual-safety lock of the present utility model, described warning device is alarming horn.
Further, Dual-safety lock of the present utility model, described warning device also can be alarm lamp.
The beneficial effect that the utility model obtains is: (1) structure is simple, (2) under the state not inserting key when manual lock, first contact, second contact and the 3rd contact are all in off-state, the circuit that now electromagnetic lock and dc source form is in closure state, now electromagnetic lock is in the lock state, manual lock is also in the lock state, thus there is double locking function, in time having people to think theft bicycle, in order to open manual lock, can specialist tools or iron wire be inserted in the lockhole of manual lock, now the first contact can be connected with the second contact by specialist tools or iron wire, be serially connected with again between dc source after warning device and electromagnetic lock parallel connection, not only electromagnetic lock can not be opened, simultaneously also can by alarm activation, given the alarm by warning device, theft personnel are avoided to take further action, thus avoid bicycle stolen, security performance is high, (3) when needs riding bicycle time, key is inserted in manual lock, close hand switch simultaneously, now the first contact is connected with the 3rd contact by key, first contact, 3rd contact, protective resistance and hand switch form a loop, make electromagnetic lock short circuit, thus by electromagnetic lock unlock, very easy to use, when needs promptly enter line-locked to electromagnetic lock time, press hand switch, now by the first contact, 3rd contact, there is open circuit in the circuit of protective resistance and hand switch composition, electromagnetic lock is short circuit no longer, thus the quick lock in realized electromagnetic lock, (4) warning device is alarming horn or alarm lamp, thus can send alarm sound or warning light, forces theft personnel to destroy electromagnetic lock or manual lock further, thus improves the security performance of whole safety lock further.

Detailed description of the invention
As depicted in figs. 1 and 2, Dual-safety lock of the present utility model, comprise manual lock 1, dc source 5, electromagnetic lock 6, warning device 7 and protective resistance 8, the first contact 2 is provided with in described manual lock 1, second contact 3 and the 3rd contact 4, keyhole is provided with in described manual lock 1, groove is provided with in described keyhole, the top of keyhole is fixed in described first contact 2, the bottom of keyhole is fixed in described second contact 3, described 3rd contact 4 is fixed in groove, between the positive pole that described electromagnetic lock 6 is serially connected with dc source 5 and negative pole, described first contact 2 is connected with the positive pole of dc source 5, be connected with the negative pole of dc source 5 again after described second contact 3 is connected in series with warning device 7, described 3rd contact 4 is connected with the negative pole of dc source 5 after connecting with protective resistance 8 again, described first contact 2 and the 3rd contact 4 are triggered by the key matched with manual lock 1, a hand switch 9 is also in series with between described protective resistance 8 and the negative pole of dc source 5, described warning device 7 is alarming horn or alarm lamp.
Dual-safety lock of the present utility model, structure is simple, when under the state that manual lock 1 does not insert key, first contact, second contact 2 and the 3rd contact 3 are all in off-state, the circuit that now electromagnetic lock 6 and dc source 5 form is in closure state, now electromagnetic lock 6 is in the lock state, manual lock 1 is also in the lock state, thus there is double locking function, in time having people to think theft bicycle, in order to open manual lock 1, can specialist tools or iron wire be inserted in the lockhole of manual lock 1, now the first contact 2 and second tactile 3 can be connected by specialist tools or iron wire, be serially connected with between dc source 5 again after warning device 7 and electromagnetic lock 6 parallel connection, not only electromagnetic lock 6 can not be opened, also warning device 7 can be started simultaneously, given the alarm by warning device 7, theft personnel are avoided to take further action, thus avoid bicycle stolen, security performance is high.
When needs riding bicycle time, key is inserted in manual lock 1, close simultaneously and manually open 9 passes, now the first contact 2 is connected with the 3rd contact 4 by key, first contact 2, 3rd contact 4, protective resistance 8 and hand switch 9 form a loop, make electromagnetic lock 6 short circuit, thus electromagnetic lock 6 is unlocked, very easy to use, when needs promptly enter line-locked to electromagnetic lock 6 time, press hand switch, now by the first contact 2, 3rd contact 4, there is open circuit in the circuit that protective resistance 8 and hand switch 9 form, electromagnetic lock 6 no longer short circuit, thus the quick lock in realized electromagnetic lock 6.
Warning device 7 is alarming horn or alarm lamp, thus can send alarm sound or warning light, forces theft personnel to destroy electromagnetic lock 6 or manual lock 1 further, thus improves the security performance of whole safety lock further.
