Abstract
The invention discloses a duplex coded anti-theft lock, which comprises a door pin (1), a door bolt (2), a movable sleeve (3), a connecting rod (4), a door bolt lifting piece (5), a movable lifting lever (6), a movable pressing rod (7), a movable cover hook (8), an inner wheel (9), a return spring (10), a support rod (11), a mechanical lock (12), a movable cover (13), a coded lock (14) and a bayonet lock (15), wherein a key is inserted to rotate the mechanical lock (12), and the movable lifting lever (6) is downwards pressed through the movable pressing rod (7), so that the movable cover hook (8) is separated to open the coded lock (14); through the combined action of the coded lock (14), the mechanical lock (12) and the movable lifting lever (6), the door bolt (2) can be lifted to open a door; and simultaneously, the door bolt (2) is vertically arranged on a door frame, so that lawbreakers cannot toggle the door bolt through a crack, and the efficacies that the coded lock cover can only be opened in such a way that the key is inserted to rotate the mechanical lock, and the door can only be opened through toggling the coded lock and rotating the mechanical lock are achieved. The duplex coded anti-theft lock is simple and reliable, is suitable to be popularized and used in door lock manufacturing enterprises and decoration industries, is suitable to be used by residents in urban and rural areas, and has very large market prospect.
Description
Technical field
The present invention relates to a kind of door lock, more particularly, the present invention relates to the doubly-linked puzzle theft-proof lock of a kind of mechanical lock and coded lock use.
Conventional mechanical door lock generally designs keeper between doorframe and the gap of door, and this door lock, as long as rotate key or back down keeper and just door can be opened, is easy to be grasped by lawless person; Conventional coded lock, its combination disk is exposed to outside, is also easy to be obtained password and open door by lawless person.At present, no matter be any door lock all because of keeper doorframe with door gap between transversal stretching, thereby cause lawless person need only keeper is destroyed, just forcing open the door enters the room carries out illegal activity.Up to the present, conventional door lock does not also solve the safe and reliable problem of door lock better.
summary of the invention
The object of the invention is to solve the deficiencies in the prior art, a kind of safer reliable doubly-linked puzzle theft-proof lock is provided.
Object of the present invention is achieved by following technical proposals.
Install mechanical lock 12 and the coded lock 14 with removable cover 13 in the positive corresponding positions of door; The correspondence position at the door back side is established the movable driving lever 6 with support bar 11 and return spring 10, movable driving lever 6 tail ends are close to the movable depression bar 7 being connected with mechanical lock 12, the front end of movable driving lever 6 is close to the door bolt lifting piece 5 being contained on doorframe, door bolt lifting piece 5 connects a door bolt 2 being contained in above in movable sleeve 3 by connecting rod 4, and door bolt 2 is with to be contained in a contact surface of the keeper of carrying on the back and extend to doorframe 1 angled and can folding; On removable cover 13, connect removable cover and hook 8, removable cover hooks 8 and links by the hole on door and movable driving lever 6; On the interior wheel 9 of coded lock 14, establish groove, inside take turns 9 grooves and engage with the bayonet lock 15 being located on movable driving lever 6 under opening.
The invention has the beneficial effects as follows:
1, in the time that reeve key rotating machinery locks 12, movable depression bar 7 rotates simultaneously and presses down movable driving lever 6, at this moment movable driving lever 6 and removable cover hook 8 depart from and open the removable cover 13 of coded lock 14, just can reveal coded lock 14, have played the object that does not make coded lock 14 expose.
2, further adjust the password of coded lock 14, make the bayonet lock 15 on the whole alignment activity driving levers 6 of groove on wheel 9 in it, rotating machinery lock 12, makes movable depression bar 7 continue to press down movable driving lever 6 again, and at this moment bayonet lock 15 engages with interior groove of taking turns on 9, movable driving lever 6 front ends lift and drive 5 liftings of door bolt lifting piece, door bolt lifting piece 5 by the whole door bolts 2 of connecting rod 4 lifting, makes it to depart from keeper 1 again, and door can be opened, otherwise door is shut.After door is shut, the groove in bayonet lock 15 departs from wheel 9, and the movable driving lever 6 of dieback, make it to stir.Reach the dual fail-safe object of simultaneously opening the door with mechanical lock and coded lock.Lawless person does not have the key of mechanical lock not open puzzle locked cap, does not understand the password of coded lock, has mechanical lock key not open door yet.
3, door bolt 2 is located on doorframe, and vertically downward, lawless person can not stir door bolt by crack between a door and its frame, thereby more safe and reliable.
4,1 pairing of door bolt 2 and keeper arranges more than 1, and can arrange multiplely, makes lawless person can not prize door leaf, and door is more firm.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further elaborated.
Embodiment 1: install mechanical lock 12 and the coded lock 14 with removable cover 13 in the positive corresponding positions of door; The correspondence position at the door back side is established the movable driving lever 6 with support bar 11 and return spring 10, movable driving lever 6 tail ends are close to the movable depression bar 7 being connected with mechanical lock 12, the front end of movable driving lever 6 is close to the door bolt lifting piece 5 being contained on doorframe, door bolt lifting piece 5 connects a door bolt 2 being contained in above in movable sleeve 3 by connecting rod 4, door bolt 2 be contained in the contact surface of the keeper of carrying on the back and extend to doorframe 1 angle at 45 ° can folding; On removable cover 13, connect removable cover and hook 8, removable cover hooks 8 and links by the hole on door and movable driving lever 6; Coded lock 14 is established more than one combination disk, in corresponding one of each combination disk, takes turns 9, inside takes turns on 9 and establishes groove, inside takes turns 9 grooves and engages with the bayonet lock 15 being located on movable driving lever 6 under opening.
