Abstract

An oscillating spring bolt for a door lock is arranged on a lock body and comprises a bolt body, a bolt base, a pin shaft and elastic elements, wherein the bolt base is arranged on the lock body, and the bolt body is hinged onto the bolt base through the pin shaft and can oscillate around the pin shaft. A front bolt surface and a back bolt surface are respectively arranged on two sides of the bolt body, the front bolt surface and a door leaf plane form a front oblique angle alpha, and the back bolt surface and the door leaf plane form a back oblique angle beta. A second blind hole is arranged at the position on one side of the bolt base deviating from the pin shaft, a bolt base inclined surface is arranged on the bolt base on the periphery of the second blind hole, and the bolt base inclined surface and the vertical surface of the door leaf plane form a bolt base oblique angle gamma. A first blind hole is arranged on the bolt body at the position corresponding to the second blind hole, and the elastic elements are respectively arranged in the first blind hole and the second blind hole and push and press the bolt base and the bolt body toward two sides. The oscillating spring bolt reduces door push force, avoids door leaf self locking, ensures door leaf positioning reliability, and can be applied to various door locks, especially special unlatched doors.

Description

A kind of door lock is used the swing type dead bolt

Technical field

The present invention relates to a kind of door lock of building, relate in particular to a kind of door lock and use the swing type dead bolt, belong to machinery manufacturing technology field.

Background technology

A common door lock that upward uses of building generally comprises two parts: embed the lock body in the door and be fixed on the keeper on the doorframe.Usually door lock inserts and is locked in the keeper through the dead bolt with lock body and locks a door, and opens the door dead bolt is withdrawed from keeper through revolving.Yet this revolving through manipulation just seems very inconvenient to the stretch mode that realizes the open and close door of control dead bolt in some cases, but as in hand, hold in both hands have object need wear door and cross do not have other people and assist to open the door in; And for example the restaurant waiter serves a dish and pushes when getting into the dining room from the kitchen.

In order to overcome the shortcoming of the above-mentioned occasion of common door lock incompatibility, occur a kind of need not the manipulation on the market again and revolved handle, only need to promote the door lock that door leaf just can be opened; They generally are used to be in the door of the state of being left unlocked or unlatched, and this door lock does not generally revolve handle, has only dead bolt; Be in when being left unlocked or unlatched state as Men Busuo; Dead bolt inserts keeper in case wind or avoid being in opening-wide state, and need only promote door leaf when needing, and dead bolt is promoted retraction by keeper can wear door and mistake.

See also Fig. 2, the cross section of Door-lock bolt 1 is generally triangle, and both sides respectively have a tongue inclined-plane before and after it; Front 11 becomes a front bevel angle α with the door leaf plane; Back lingual surface 12 becomes a back bevel angles β with the door leaf plane, in general, the front bevel angle α of dead bolt and back bevel angles β are 45 °; Thereby for the door leaf that fixed thickness is arranged, the length of dead bolt 1 (being the distance of the tip of the tongue to the dead bolt root) is exactly certain.This have fixing lingual surface oblique angle, door lock that fastened tabs is long and be used for above-mentioned door when lasting of being left unlocked or unlatched, and some problems will occur sometimes: when the lingual surface of dead bolt 1 or keeper contact surface are rough, push and will feel that ten minutes is heavy; When the crack between a door and its frame between door leaf and the doorframe was big, the degree of depth that dead bolt 1 stretches into keeper was just not enough, thereby caused the door leaf location unreliable; Or the like.

In order to address the above problem; Application number is that 201110452912.9 one Chinese patent application " handle be left unlocked or unlatched door lock " without spin provides a kind of door lock; Its dead bolt has the asymmetric double lingual surface; And wherein thereby a lingual surface oblique angle has guaranteed that much smaller than the length of 45 ° of dead bolts 1 that extended dead bolt 1 stretches into keeper enough degree of depth are arranged.Though this patent application has solved door leaf and located insecure problem, diminish and cause the power that pushes to become the phenomenon of big even door leaf self-locking but produced the lingual surface oblique angle.

Summary of the invention

The present invention is directed to the deficiency of prior art, provide a kind of door lock to use the swing type dead bolt, the door lock that adopts this dead bolt is installed in is left unlocked or unlatched a last time, can reduce the power of pushing, avoid the door leaf locking phenomenon, realize the purpose that easily pushes and come in and go out.

The present invention realizes through following technical scheme:

A kind of door lock is used the swing type dead bolt, is installed on the lock body, and it comprises tongue body, tongue seat, bearing pin and flexible member; Said tongue base device is on said lock body; Said tongue body is articulated on this tongue seat through bearing pin and can swings around this bearing pin, and these tongue body both sides are respectively equipped with front and back lingual surface, and this front and door leaf plane form front bevel angle α; This back lingual surface and door leaf plane form back bevel angles β; A side place that departs from bearing pin on the said tongue seat is provided with second blind hole, and the tongue seat around this second blind hole is provided with tongue seat inclined-plane, and the vertical plane on this tongue seat inclined-plane and door leaf plane forms tongue seat oblique angle γ; Position corresponding with second blind hole on the said tongue body is provided with first blind hole, and said flexible member is arranged in this first blind hole and second blind hole and with said tongue seat and tongue body and pushes to both sides.

Door lock of the present invention is used the swing type dead bolt, and its front bevel angle α is 10 °～35 °, and back bevel angles β is 30 °～45 °, and tongue seat oblique angle γ is 8 °～18 °; Said flexible member is a cylindrical compression spring.

Compared with prior art, door lock of the present invention can be obtained following beneficial effect with the swing type dead bolt:

1, the present invention is provided with the flexible member that is offset to hinge pin axle one side between tongue seat that is hinged and tongue body; Therefore, when door leaf by when rear side promotes, tongue body just can and be swung around bearing pin by the promotion of the keeper on the doorframe; Make the angle of front bevel angle α become big; Thereby reduced the power of pushing, avoided the phenomenon of door leaf self-locking, reached the effect that easily pushes and come in and go out.

2, tongue body of the present invention has and is not more than 45 ° less front bevel angle α and back bevel angles β; Thereby the length of the dead bolt that extended; Reach most more than 1.4 times of common dead bolt; Thereby guaranteed the reliable of door leaf location, even the crack between a door and its frame gap is bigger or when fitful wind is arranged, still can keep the door leaf to be in the state of being left unlocked or unlatched reliably.
