Abstract

The utility model relates to a lock tongue device which comprises lock box. A lock tongue forms a slide fit with an opening of a cover plate arranged on the outer side of the lock box. The middle of the back surface of the lock tongue is hinged with a tongue connecting sheet. The back surface of the lock tongue on both sides of the tongue connecting sheet is provided with two counter bores. A lock tongue telescopic spring is inserted in the counter bores. The tongue connecting sheet extends from the back surface of the lock tongue out of the lock box through an opening arranged on the box wall of the inner side of the lock box to be connected with a lock core. One side of the lock tongue is fixedly connected with a lock tongue locking and unlocking mechanism. An action sensing component of the mechanism is a driving rod with a door closing probe. The door closing probe of the driving rod is arranged in the hole position of the cover plate arranged on the outer side of the lock box beside the lock tongue. As the lock tongue device is provided with a lock tongue locking and unlocking mechanism, the probe is touched when a door is closed. The lock tongue can be automatically unlocked, and the lock tongue can be automatically bounced to lock the door. When the door is opened, the mechanism can lock the lock tongue automatically without extending to affect the post door closing actions and the problem that the lock tongue can not be controlled is solved by a simple mode.

The specific embodiment

As Fig. 1-shown in Figure 4, in this exemplary embodiment, comprise lock box 1, slidable fit has dead bolt 3 in the opening of the balustrade deching 2 of lock box 1, the company's of being hinged with tongue piece 4 in the middle of the back side of dead bolt 3, dead bolt 3 back sides have two counterbores in company tongue piece 4 both sides, be fitted with dead bolt Telescopic spring 5 in the counterbore, company's tongue piece 4 self-locking dorsal surface of tongue stretch out lock box 1 by the opening on the lateral box wall in the lock box 1 backward and are connected with lock core, side at dead bolt 3 is installed with locking and release mechanism of a cover dead bolt 3, the action sensing element of this mechanism is one to have the drive link 7 that closes gate probe 6, and the pass gate probe 6 of drive link 7 is arranged on the tapping of the balustrade deching 2 of dead bolt next door lock box.

Lock and release mechanism comprise the block tongue frame 8 that is fixed on the lock box base plate, perpendicular to slidable fit in the chute of dead bolt 3 directions of motion block tongue sheet 9 is arranged in the block tongue frame 8, the outside of block tongue sheet 9 is equipped with pushing spring 10, the direction of motion that is parallel to dead bolt 3 in the block tongue frame 8 is provided with a through hole 11, install drive link 7 in the through hole 11, what block tongue sheet 9 was provided with a correspondence in these through hole 11 positions pushes away hole 12 partially, this pushes away the outer hole wall in hole 12 inwardly departs from a setting than the outer hole wall of above-mentioned through hole 11 corresponding positions distance partially, drive link 7 is provided with a conical surface section 20 that is used to produce inclined to one side thrust at this correspondence position, drive link 7 is provided with conical probe 6 at lock box balustrade deching 2 places, be coated with back-moving spring 13 on the conical probe 6 medial segment drive links 7, be fixed with anticreep pad 14 on the inner termination of drive link 7, the inboard termination of block tongue sheet 9 and the cotter way 15 of dead bolt corresponding position are in the door opening state clamping matching that locks mutually.

Slide on lock box 1 inwall of position at dead bolt 3 back sides and to be pasted with the automatic clamp 16 of a dead bolt, the automatic clamp 16 of dead bolt is provided with dead bolt Telescopic spring 5 and passes the hole with the correspondence that connects tongue piece 4, one side of the automatic clamp 16 of dead bolt is equipped with back-moving spring 17, is provided with the spacing top board 18 of dead bolt on the automatic clamp of dead bolt of the lateral deviation position between the automatic clamp 16 of dead bolt and the dead bolt back side.

Start when opening the door when connecting tongue piece 4, the automatic clamp 16 of dead bolt up slips and makes spacing top board 18 skews allow open position, allows dead bolt 3 indentations; After dead bolt 3 indentations, block tongue sheet 12 sticks into block tongue sheet 9 in the cotter way 15 of dead bolt top by the effect of pushing spring 10, makes dead bolt 3 not emit, and promptly door is opened.When at closing time, probe 6 is pressed into to drive to move also in the drive link 7 and moves on the push card tongue piece 9, dead bolt 3 just ejects under the effect of dead bolt Telescopic spring 5 automatically, the automatic clamp 16 of dead bolt resets downwards under the effect of back-moving spring 17 simultaneously, because of the position-limiting action of spacing top board 18 is stuck in again on dead bolt 3 back sides, make not retractable of dead bolt 3.
