Description
Technical field
The utility model relates to a kind of door lock, particularly a kind of antitheft door lockset; The utility model also relates to the matching used key of a kind of and aforementioned antitheft door lockset.
Background technology
Door lock is a kind of anti-theft tool that people commonly use, but the door lock generally used now, and in its lock core, pellet or blade are exposed in locked groove, with master key, hit spoon or now popular tinfoil unlocking method be easy to just lock to be opened, theftproof performance is poor.And present lock core structure complexity, lock is easy to damage in use.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides a kind of reasonable in design, easy to use, the antitheft door lockset that theftproof performance is good.
Another technical problem to be solved in the utility model is to provide the matching used key of a kind of and above-mentioned antitheft door lockset.
Technical problem to be solved in the utility model is to realize by following technical scheme, the utility model is a kind of antitheft door lockset, be characterized in: comprise lock housing, the front of lock housing is provided with key mouth and spanner, the sidewall of lock housing is provided with at least two dead bolt holes, be fixedly connected with latch plate in lock housing, be provided with the mortise lock groove be communicated with the key mouth in latch plate, be provided with the dead bolt coordinated with dead bolt hole between latch plate and lock housing side plate, dead bolt is fixed on bolt plate, the lower end of bolt plate is connected with the tongue bar, on the tongue bar, back-moving spring is housed, lock housing is provided with the locking mechanism of unblanking coordinated with bolt plate, rear in latch plate is provided with unlocking mechanism, described unlocking mechanism comprises several levers setting up and down and the Eccentric Circular Ring be connected with spanner, be provided with the plectrum of propping up lever between several levers, plectrum is fixedly connected on Eccentric Circular Ring, be provided with between lever and also be provided with return spring, be respectively equipped with the support slot with lever mated in the upper and lower of latch plate, be provided with on bolt plate and the anterior through hole coordinated of lever, also be connected with the driving lever coordinated with back-moving spring on the tongue bar on described plectrum, one side of Eccentric Circular Ring is provided with the baffle plate that covers lockhole, and latch plate is provided with the long through-hole coordinated with baffle plate.
Technical problem to be solved in the utility model can also further realize by following technical scheme, the locking mechanism of unblanking comprises the rotating shaft of vertical setting, the front of lock housing is provided with the knob be connected with rotating shaft, rotating shaft is provided with and coordinates the locking hook with bolt plate, and locking hook and rotating shaft are provided with limit spring.
Technical problem to be solved in the utility model is to realize by following technical scheme, the utility model is a kind of and the matching used key of antitheft door lockset, be characterized in: the sheet key body that described key comprises the sheet the shank of the key and is connected with the shank of the key, the sheet the shank of the key is provided with the slotted hole coordinated with baffle plate, and the both sides up and down of sheet key body are respectively equipped with the draw-in groove with lever mated.
The utility model is different from traditional safe-guard door lock structure, it does not have lock core, key does not produce rotation in use, and the slotted hole first passed on the key by a baffle plate before unblanking covers the key mouth, thereby in the situation that there is no key, all unlocking tools can't be operated, because key does not rotate, and stressed hardly in the process of unblanking, so key can be done very thinly, the mortise lock groove is a long finedraw, thereby more antitheft.
Compared with prior art, the utility model is simple in structure, easy to make, and theftproof performance is good, has covered lockhole when unblanking, and theftproof performance is increased greatly, and owing to there is no lock core, each parts can obtain with metal-made, and the performance that anti-violence is unblanked also increases greatly.
The accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model.
Fig. 2 is Fig. 1 plan structure schematic diagram.
Fig. 3 is the structural representation of key.
The specific embodiment
Referring to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands the utility model further, and do not form the restriction to its right.
During use, at the state pinned, the spanner 15 that first turns clockwise, plectrum 12 erects and props up several levers 2,14 from the level rotation, simultaneously because spanner 15 rotations make off-centre operation rotarily drive baffle plate 8 and move away lockhole.Like this key 16 is inserted to the mortise lock groove from 16 mouthfuls of keys, another mistake hour hands rotary spanner 15, the driving lever 9 be connected with plectrum 12 rotarilys actuate tongue bar 10 and moves backward, and make back-moving spring 11 pressurizeds, thereby drive bolt plate 7 and dead bolt 6 retreat through lever 2,14 side plate that leaves lock housing 1, the locking hook 5 of bolt plate 7 locking mechanism of being unblanked catches on, lock is opened, when spanner 15 is rotated counterclockwise, baffle plate 8 can be through the slotted hole on sheet the shank of the key 19, and lever 2,14 also can ride on the draw-in groove 20 of sheet key body 18.While again needing to lock, turn knob 17, locking hook 5 rotation release lock hyoplastrons 7, back-moving spring 11 decompress(ion)s and bolt plate 7 is resetted, dead bolt 6 stretches out has locked, and at the spanner 15 that turns clockwise, plectrum 12 is propped up lever 2,14, key 16 can be extracted, another mistake hour hands rotary spanner 15 makes baffle plate 8 cover lockhole.
