Abstract
The utility model relates to an anti-theft lock with an inclined bolt buckling function. The anti-theft lock comprises a lock body, wherein an inclined bolt and an inner handling shifting sheet are arranged in the lock body, and a reset spring, a positioning sheet and a sliding guide sheet are arranged at the rear end of the inclined bolt. The sliding guide sheet and the inclined bolt are arranged integrally, and one end of the inner handling shifting sheet is in butting matching with the sliding guide sheet. An inclined bolt buckling mechanism is further arranged in the lock body and can buckle the sliding guide sheet when the inclined bolt shrinks into the lock body to enable the inclined bolt to be in an inner-shrinking state. The locking buckling on the sliding guide sheet is removed by the aid of shifting of the inner handling shifting sheet, and then the inclined bolt extends out of the lock body under the effect of the reset spring. The inclined bolt buckling function is added on the anti-theft lock, the inclined bolt can be pressed down by hands when the lock body is not started, the inclined bolt retreats into the lock body and is buckled, and a door cannot be locked when the door is closed. Therefore, in house decorating, a house owner does not need to give keys to constructors, and the anti-theft lock is particularly suitable for being used in engineering projects.
Description
Technical field:
The utility model relates to door latch structure, especially a kind of theftproof lock with button latch bolt function.
Background technology:
As everyone knows, the i.e. locking voluntarily after touching doorframe of the latch bolt on the safe-guard door lock, indoor can opening by handle outdoorly then opened with key.When the resident family that security door is housed need fit up, the householder generally will give the constructor with key, after the finishing completion, regain again key, because constructor's quality is uneven, sometimes the phenomenon that key is joined to walk or lost to other people can occur unavoidably, thereby bring potential safety hazard for householder's indoor property, also some more careful householder can change a safe-guard door lock again after the finishing completion, can for no reason increase so again householder's decoration cost, therefore await improving.
The utility model content:
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, and a kind of theftproof lock with button latch bolt function is provided, and it can not press latch bolt with hand when lock body starts, and makes latch bolt return in the lock body and be fastened, and close the door this moment can be with on the door lock.
The purpose of this utility model is achieved through the following technical solutions:
A kind of theftproof lock with button latch bolt function, comprise lock body, be provided with latch bolt and interior handle plectrum in the described lock body, described latch bolt rear end is provided with back-moving spring, spacer and slide guide sheet, described slide guide sheet and latch bolt Integral design, one end of described interior handle plectrum is supported with the slide guide sheet and is cooperated, also be provided with a button latch bolt mechanism in the described lock body, this button latch bolt mechanism fastens described slide guide sheet in the time of being reduced in the lock body in described latch bolt, make latch bolt keep inside contracting state, and remove snap close to described slide guide sheet according to stirring of described interior handle plectrum, make latch bolt under the effect of back-moving spring, stretch out lock body.
Described button latch bolt mechanism comprises a buckle and a buckle torsion spring, described buckle one end is rotationally connected with the bearing pin that is arranged in the lock body, the other end is buckled on the described slide guide sheet in the time of can being reduced in the lock body in described latch bolt, and complies with the snap close of removing described slide guide sheet of stirring of described interior handle plectrum.
Also be provided with tapered end, master latch, master latch supporting plate, master latch toggle mechanism, master latch lock-out state position-limit mechanism in the described lock body, described master latch lock-out state position-limit mechanism is supported with the other end of described interior handle plectrum and is cooperated.
Compared with prior art, the beneficial effects of the utility model are:
Increased a button latch bolt function, this function can not pressed latch bolt with hand when lock body starts, and makes latch bolt return in the lock body and be fastened, and close the door this moment can be with on the door lock.Therefore when house decoration, even if the householder does not provide key, the constructor does not worry being locked yet, thereby has avoided in the fitment process, when key is provided to bring many unfavorable of householder and the inconvenience of bringing to the constructor when not providing key.In the time will removing this function, insert key towards the opening direction 90-degree rotation or press down 45 degree with handle inside and can recover normal condition, be particularly suitable for being installed on object of construction production with locking.
Description of drawings:
Introduce in detail the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation that latch bolt is return lock body in the utility model.
Fig. 2 is the structural representation that latch bolt is stretched out lock body in the utility model.
The specific embodiment:
As depicted in figs. 1 and 2, as a kind of embodiment of the utility model, this theftproof lock with button latch bolt function comprises lock body 1, is provided with latch bolt 2 and interior handle plectrum 3 in the lock body 1, and latch bolt 2 rear ends are provided with back-moving spring 4, spacer 5 and slide guide sheet 6.Slide guide sheet 6 and latch bolt 2 Integral designs can be to fix, be welded as a whole, and also can be one-body molded.One end of interior handle plectrum 3 is supported with slide guide sheet 6 and is cooperated, also be provided with a button latch bolt mechanism 7 in the lock body 1, this button latch bolt mechanism 7 comprises a buckle 71 and a buckle torsion spring 72, buckle 71 1 ends are rotationally connected with the bearing pin 20 that is arranged in the lock body 1, the other end can be reduced to lock body 1 and be buckled on the slide guide sheet 6 when interior in latch bolt 2, make latch bolt 2 keep inside contracting state, and comply with the snap close of removing slide guide sheet 6 of stirring of interior handle plectrum 3, make latch bolt 2 under the effect of back-moving spring 4, stretch out lock body 1.
