Abstract

A semiautomatic lock of roll-up doors is a lock, which includes two lock tongue axes which are in parallel, a connecting plate, a lock slider, a lock shell, a reset spring and a locking device. A traction plate is positioned between the lock tongue axes and the lock slider; the traction plate is provided with a vertical slide axis; the reset spring is connected between the lock shell and the vertical slide axis. The lock shell is provided with a swinging and translating guide groove; one end of the swinging and translating guide groove which is close to a paddle is provided with an anti-opening recess area; one end of the paddle is fixed to the lock core, and the other end leans to the vertical slide axis; when working, the paddle toggles the vertical slide axis to swing and more to a polar bit along the swinging and translating guide groove. At this time, the locking device clasps the lock tongue axis. The utility model is in a double-tongue opening way, with low noise upon locking and unlocking, and locking is reliable, which is applicable to all roll-up door locks.

Description

The semi-automatic lock of rolling door

Technical field

The utility model relates to a kind of lockset, especially a kind of rolling screen door lock.

Background technology

Rolling door is a management place security door commonly used, and the lock that uses in the rolling door mostly is common lock, and theftproof performance is low.Have a kind of " rolling door automatic locking " more common rolling screen door lock on anti-theft feature that is published by patent No. ZL0124719.2 to strengthen to some extent now, structure also improves to some extent, in the use simple and convenient some.But this lock generally uses on the monolock tongue, in the use of locking of double lock tongue and many dead bolts, will adopt the functional entity of two times or many times, and it is poor to open and close the lock resiliency, and wherein a kind of embodiment is reliable inadequately on locking function.Need on structure and the locking function to improve.

Summary of the invention

The utility model purpose be to provide a kind of many tongues lock use, the semi-automatic lock of the little and reliable lock of noise when opening and closing lock.

The utility model comprises tapered end, lock core, lock housing, dead bolt axle, lock bolt sleeve and return spring; Lock bolt sleeve is installed on the lock housing, and dead bolt axle cunning is contained in the lock bolt sleeve, and tapered end then is installed in the lock housing, and the dead bolt axle has 2 and them to be parallel to each other, and the end of dead bolt axle in lock housing is connected with junction plate, is fixed with big riveting axle and little riveting axle on the junction plate; Between dead bolt axle and the tapered end drawing plate is arranged, drawing plate is hinged on the big riveting axle near an end of junction plate, and the other end of drawing plate has perpendicular perpendicular slide-bar, and return spring then is connected between perpendicular slide-bar and the lock housing; Lock housing panel inner face has the swinging translational guide groove, the swinging translational guide groove stretches along the rotation direction of unblanking, and be arcuation, lock core is connected with dials plate, an end of dialling plate is fixed on the lock core, and the other end of dialling plate leans against on the perpendicular slide-bar, and the big riveting axle on the junction plate is positioned on the geometirc symmetry axis of 2 dead bolt axles, when locking, the perpendicular slide-bar on the drawing plate is between the geometirc symmetry axis and group plate of 2 dead bolt axles; Stir perpendicular slide-bar upwards swing and the translation in the swinging translational guide groove on the drawing plate when dialling plate work; Lock housing also is hinged with the locking device of dead bolt axle, and locking device comprises swing hook and torsion spring, and dead bolt axle swing hook when the back utmost point position of withdrawal in the lock housing hooks the little riveting axle on the junction plate.The swinging translational guide groove of lock housing panel inner face is having the anti-recess of opening near an end of dialling plate, the anti-recess of opening is the shrinkage pool of swinging translational guide groove lower extreme point near the tapered end direction.

Description of drawings

Further the utility model is elaborated below in conjunction with embodiment and accompanying drawing:

Fig. 1 is the schematic diagram of unblanking of the utility model embodiment;

Fig. 2 is the locking schematic diagram of embodiment;

Fig. 3 is the swing hook schematic diagram;

Fig. 4 is a lock housing panel inner face swinging translational guide groove outline drawing.

The specific embodiment

Referring to figs. 1 through Fig. 4, embodiment comprises tapered end 4, lock

core

3,12,2 lock bolt sleeves 13 of 6,2 parallel dead bolt axles of lock housing and return spring 11, and lock bolt sleeve 13 is installed on the lock housing 6, dead bolt axle 12 sliding being contained in the

lock bolt sleeve

13, and 4 of tapered ends are installed in the lock housing 6.Article 2, the end of dead bolt axle 12 in lock housing 6 is connected with junction plate 1, and riveting has big riveting axle 2 and little riveting axle 10 on the junction plate 1, and big riveting axle 2 is riveted on the symmetrical center line of 2 dead bolt axles; Between dead bolt axle 12 and the tapered end 4 drawing plate 9 is arranged, drawing plate 9 one ends are hinged on the big riveting axle 2, and perpendicular slide-bar 8 is fixed in the other end of drawing plate 9, and 11 of return springs are connected between lock housing 6 and the perpendicular slide-bar 8.Lock housing 6 panel inner faces have swinging translational guide groove 5, swinging translational guide groove 5 is arcuation, and lock core 3 is connected with dials plate 14, and swinging translational guide groove 5 is having the anti-recess 17 of opening near an end of dialling plate 14, prevent opening recess 17 in swinging translational guide groove 5 lower ends, an end of dialling plate 14 is fixed on the lock core 3; The perpendicular slide-bar 8 of stirring the swinging translational device when dialling plate 14 work is along upwards swing and translation of swinging translational guide groove 5.Lock housing 6 also is hinged with the locking device of dead bolt axle, and locking device is made up of swing hook 7, torsion spring 16, baffle plate 15 and unlocking knob, and dead bolt axle 12 is the little riveting axle 10 on the swing hook 7 hook position junction plates 1 when the back utmost point position of withdrawal in the lock housing 6.During blocking, dead bolt axle 12 stretches out lock bolt sleeve 13, and the perpendicular slide-bar 8 of drawing plate 9 imports anti-opening in the recess 17, and drawing plate 9 relative 2 dead bolt axle 12 centre symmetry line are flapped toward down (see figure 2), and swing hook 7 is subjected to torsion spring 16 twisting forces clockwise and spacing by baffle plate 15.This moment is if dead bolt axle 12 contracts in stressed, owing to be positioned at the opposite side of swinging translational guide groove 5, perpendicular slide-bar 8 can only move backward in the recess 17 and is obstructed securely anti-opening, and that is to say that locking is reliable.The process of unblanking, key rotation lock core 3, with lock core 3 affixed dial plate 14 also thereupon up time rotate and stir the perpendicular slide-bar 8 that is positioned at swinging translational guide groove 5 and move along swinging translational guide groove 5, thereby drive junction plate 1 and dead bolt axle 12 in lock housing 6 translation until utmost point position, little rivet 10 on the junction plate 1 falls in the swing hook 7 just at this moment, moves on the utmost point position in 12 on dead bolt axle is hooked in securely.The process of unblanking also finishes thereupon.The baffle plate 15 of locking device has vertical edge, baffle plate 15 is fixed together with unlocking knob, swing hook 7 is hinged on the lock housing 6, during block action, clockwise rotates unlocking knob, baffle plate 15 is also rotating thereupon, rotate counterclockwise thereby promote swing hook 7, swing hook 7 thereby break away from little riveting axle 10 is under the reset force effect of return spring 11,1 speed of junction plate moves and promotes dead bolt axle 12 to lock bolt sleeve 13 directions and moves simultaneously until stretching out utmost point position and falling in the locating hole of guiding groove, and rolling door is locking firmly just.

The two tongues of the utility model are opened, and open and close the little and reliable lock of lock process noise, and it is applicable to all rolling screen door locks.
