Description

Special crab-claw bolt anti-theft alarm door lock

The utility model relates to lockset, is a kind of insurance lock that belongs to cylinder lock and have warning function.

In existing pin tumbler lock technology, the dead bolt structure of all kinds of locksets is all similar, fairly simple, is generally single tongue lockset, and also having some is two tongue locksets, and the contour structures of dead bolt has plenty of oblique tongue, has plenty of the rectangle tongue.Two tongue locksets are than the safety height of single tongue lockset.But these present dead bolts are unitary structure, after lockset is locked, dead bolt is set in the little shell on the doorframe only straight-throughly, just because its just straight-through being set in the little shell, so this monomer-type dead bolt is unable to undergo to dial, sled, as long as stretching into crack between a door and its frame with foreign matter stirs dead bolt, dead bolt is removed the locking function with regard to being easy to displacement.The height of the general safety of all thinking lock depends on tapered end mechanism, and there is no question about for this, but if can have one need not key operatedly just dial motionless, the dead bolt of prizing not open, the safety that will improve lockset greatly.In addition, existing pellet shot from a slingshot insurance lock does not mostly have warning function, in case the picking lock phenomenon takes place, also Nobody Knows, can only let matters drift.

The purpose of this utility model is for a kind of safe-guard door lock with special construction dead bolt being provided, making it after the lockset locking, promptly use powerfully dial, sled, even with the way of impact, all can't mobile dead bolt locked position, to guarantee the safety of lockset.Another purpose of the present utility model is to set up a warning function for lockset, makes it that lockset can send alarm sound when unblanking without normal mode.

It is the same with existing all kinds of pin tumbler lockes that the purpose of this utility model is achieved in that, the utility model includes also that big shell, base plate, tapered end mechanism, tapered end are dialled peach, the dead bolt assembly, sled mechanism, interior handle and the handle that are made of dead bolt and hyoplastron are dialled peach, doorframe is locked little shell.The design has done unique improvement to the dead bolt assembly, mainly is to have comprised a pair of chain hook tongue, and each chain hook tongue has an opening hook groove that contains upper and lower interior angle, and the last interior angle of opening hook groove is generally the obtuse angle, and following interior angle is generally acute angle.This a pair of chain hook tongue is arranged on the dead bolt both sides, and concrete structure is: the dead bolt bilateral symmetry of dead bolt assembly open and be shaped on a groove, chain hook tongue is inlayed hinge in this symmetrical grooves with its hook channel opening external position.When having the lockset locking of this compound dead bolt assembly,, dead bolt realizes in the dead bolt hole of little shell that the blocking function, the chain hook tongue in the dead bolt grooves on two sides is the upper and lower edge of the dead bolt hole of the little shell in hook jail simultaneously except that being set in straight-throughly.Warning function of the present utility model is realized as follows: tapered end is dialled the peach vicinity and is provided with a gauge tap that is electrically connected with known warning device on base plate, dials the peach vicinity in interior handle again and is provided with an alarm switch that is electrically connected with above-mentioned same warning device.Gauge tap plays alarm condition setting effect, promptly dials peach with the key turns tapered end and sets the opening and closing state with touch control switch; Alarm switch plays the warning effect, when gauge tap is set to " closure " state, promptly is in when needing alarm condition, and handle is dialled peach and when touching alarm switch, warning device then sounds the alarm in rotating.

In the utility model, the last interior angle of chain hook tongue opening hook groove is the best to get 92-95 degree angle.

Therefore, because the dead bolt of dead bolt assembly partly is a kind of compound dead bolt in the utility model, have a straight-line dead bolt and colonize in a pair of chain hook tongue of doing swing in the dead bolt bilateral symmetry groove, when lockset is in blocking, dead bolt runs through in the dead bolt hole of little shell, and simultaneously, chain hook tongue is the upper and lower edge of the little shell dead bolt hole in hook jail then, direction put by hook and the dead bolt moving direction is perpendicular, can very stop dead bolt contracting under non-normal condition to be moved effectively.So, the utlity model has powerful pick-proof, anti-ly unload, antitheft effect, no matter use any instrument, even unload the latch of Xiamen, also can't pry open this lockset, guaranteed the safety of lockset.Gauge tap in the utility model and alarm switch; play alarm settings and steal the alert effect of information; as the people at picking lock or have interior handle that the stranger desires rotation lock after enter house elsewhere again to open lockset when run away in the gate; lockset promptly sends chimes of doom, takes safeguard measure rapidly with reminds people.The utility model is simple in structure, as long as change the structure of dead bolt assembly and increase by two switches that are electrically connected with warning device, can play powerful antitheft and warning effect.So the utility model is applicable on the various pin tumbler lockes such as comprising single tongue lock, two tongue lock or skew bolt lock, rectangle tongue lock and adopts.

Embodiment of the present utility model as shown in drawings.Below in conjunction with accompanying drawing the utility model is described specifically.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the lateral view of the dead bolt part of dead bolt assembly in the utility model.

Fig. 1, embodiment illustrated in fig. 2 be that a kind of dead bolt 5 of dead bolt assembly is the lockset of rectangle tongue, be blocking shown in the figure.Among the figure, 1 is the big shell of lock in order to load whole latch fitting, and 2 is the little shell of lock that places for dead bolt on the doorframe in order to be fixed on.See by figure, the dead bolt assembly of device in big shell is made up of dead bolt 5 and hyoplastron 16, and wherein, dead bolt 5 bottom mid portions are shaped on a groove 6, the upper end mid portion of hyoplastron 16 is shaped on a flange 7, and flange 7 both sides are provided with and the perpendicular backup plate 8 of hyoplastron 16 plate faces; Hyoplastron 16 is solidified as a whole dead bolt 5 and hyoplastron 16 with rivet 15 be entrenched in the groove 6 of dead bolt 5 with its flange 7 after.See by figure again, open to dead bolt 5 bilateral symmetry and be shaped on groove 4, be hinged with bearing pin 13 in place, nearly bottom after a pair of chain hook tongue 3,9 is embedded in this groove 4.The hook groove 11 of chain hook tongue 3,9 toward the outer side, in the present embodiment, the last interior angle 10 of hook groove 11 be 93 the degree angles, following interior angle 12 is an acute angle.After chain hook tongue 3,9 usefulness bearing pins 13 are hinged in the groove of dead bolt 5, but hook is put the edge of big shell 1 and little shell 2 in its hook groove 11, and the exterior angle 14 of going to the bottom of chain hook tongue 3,9 can be resisted against on the backup plate 8 of hyoplastron 16.See by figure again, present embodiment is provided with the warning device that is made of warning circuit 19, loudspeaker 20 and battery 21 under big shell 1, the switch of controlling this warning device has two, and wherein one is gauge tap, be arranged on the base plate nearly tapered end and dial the peach place, dial peach with tapered end and can touch and exceed; Another is an alarm switch, is arranged on handle and dials near the peach, dials peach with handle and can touch and exceed.Whether gauge tap will report to the police in order to set, and dials peach with the lock core of key turns tapered end mechanism and tapered end and sets; Alarm switch is in order to implement reporting to the police, and during handle, handle is dialled peach 17 and touched alarm switches 18 closures within rotating lockset, and 19 connections of warning circuit realize reporting to the police.
