Description

Snap-on indicating lock and door bolt seat thereof

Technical field

The utility model relates to a kind of lockset, particularly a kind ofly is applied to snap-on indicating lock and the door bolt holder structure thereof that door-plate is opened or lock is pulled.

Background technology

General public place such as school, speedway rest station or scenic spot etc. are provided with the interim public dressing room that uses for student, driving or visitor.

And public dressing room is when avoiding using, there is unwitting people to swarm into suddenly, the lockset of a handled easily can be set between door-plate and doorframe, this lockset generally includes a card door bolt and a door bolt seat, this card door bolt has the dead bolt and an indicating piece of a slidingtype, operating this dead bolt opens or locks when pulling door-plate, this indicating piece can with the switching different colours, outdoors people is clear to know its user mode and make, as: green expression unlocking condition, the state of pulling is locked in red expression, so this kind lockset is called indicating lock again.Yet the card door bolt and the door bolt seat of this indicating lock are state separately at ordinary times, when door-plate is subjected to wind blows, cause door-plate knocking door case or card door bolt through regular meeting, not only can cause annoying noise, and might damage its partition architecture or lock structure.

Cause for this reason, but and develop the indicating lock that a kind of this door-plate of buckle, the bump of avoiding the door-plate wind-engaging to be produced with solution, and can not cause and be pulled by lock and can't be from the awkward situation of external opening.See also Fig. 1, be the structural representation of the indicating lock of existing windproof bump.As shown in FIG., this indicating lock 10 comprises a pedestal 11 that is installed on a door-plate 20 ora terminalis, and a door bolt seat 12 that is arranged at a doorframe 30 ora terminalis, has a spring snap type dead bolt 111 and a fixed dead bolt 112 in this pedestal 11.This spring snap type dead bolt 111 utilizes elastic force and this doorframe 30 of packing, forms the effect of these door-plate 20 positions of temporary transient clip, with the bump that prevents that these door-plate 20 wind-engagings from being produced, only need pull at or push open during opening-closing door and get final product.Revolving being located at this door-plate 20 inside of this fixed dead bolt 112, operation back and can the semipermanent lock pull and in this door bolt 12, reach the effect of locking.Yet, the indicating lock 10 of this kind double lock tongue, not only comparatively complicated and the degree of difficulty when increasing assembling of structure, and when installing, when the spacing dimension between door-plate and the doorframe is too big and be difficult for fastening, spacing hour then is difficult for snapping in very much, and its part is made and use costs by numerous also can increasing.

Hereat, because above-mentioned disappearance, the utility model provides the structure of a kind of snap-on indicating lock and door bolt seat thereof, its utilization is divided into one first axostylus axostyle and one second axostylus axostyle of one first housing both sides, and drive the single dead bolt of this slide plate, or this first axostylus axostyle of turn and can open a door-plate by the outside, this second axostylus axostyle interlock of turn and being opened or lock this door-plate of pulling by inside is once to solve the demand of windproof and opening-closing door.

Summary of the invention
