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 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 swing type dead bolt, belong to machinery manufacturing technology field.

Background technology

The upper common door lock using of door of building generally comprises two parts: embed the lock body in door and be fixed on the keeper on doorframe.Conventionally door lock is locked a door by the dead bolt of lock body is inserted and is locked in keeper, by revolving, dead bolt is exited to keeper, opens the door.Yet, thisly by manipulation, revolve the mode of controlling dead bolt and stretch to realize open and close door just seemed to very inconvenient in some cases, but as held in both hands in hand, have object need wear door and when crossing and assist to open the door without other people; And for example restaurant waiter serves a dish and pushes when entering dining room from kitchen.

In order to overcome common door lock, be not suitable with the shortcoming of above-mentioned occasion, on market, occurred again that a kind of need not manipulation revolve handle, only need to promote the door lock that door leaf just can be opened, they are generally used in being left unlocked or unlatched on the door of state, and this door lock does not generally revolve handle, only has dead bolt, as Men Busuo and when being left unlocked or unlatched state, dead bolt inserts keeper with Anti-blow-open or avoids in opening-wide state, and need only promote door leaf while needing, and dead bolt is promoted retraction by keeper can wear door and mistake.

Refer to Fig. 2, the cross section of Door-lock bolt 1 is generally triangle, before and after it, both sides respectively have a tongue inclined-plane, front 11 becomes a front bevel angle α with door leaf plane, rear lingual surface 12 becomes a back bevel angles β with door leaf plane, in general, αHe back bevel angles, the front bevel angle β of dead bolt is 45 °, thereby for the door leaf that has fixed thickness, the length of dead bolt 1 (being that the tip of the tongue is to the distance of dead bolt root) is exactly certain.Thisly there is fixing lingual surface oblique angle, fixedly the long door lock of tongue is left unlocked or unlatched when upper for above-mentioned, sometimes just there will be some problems: when the lingual surface of dead bolt 1 or keeper contact surface are when rough, push and will feel very heavy; When the crack between a door and its frame between door leaf and doorframe is larger, the degree of depth that dead bolt 1 stretches into keeper is just not enough, thereby causes door leaf location unreliable; Etc..

In order to address the above problem, the Chinese patent application < < that application number the is 201110452912.9 without spin door lock > > that is left unlocked or unlatched of handle provides a kind of door lock, its dead bolt has asymmetric double lingual surface, thereby and wherein a lingual surface oblique angle, much smaller than 45 ° of length that lengthen dead bolt 1, has guaranteed that dead bolt 1 stretches into keeper and has enough degree of depth.Although this patent application has solved door leaf and located insecure problem, but produced the diminish power that causes pushing of lingual surface oblique angle, become the large even phenomenon of door leaf self-locking.

Summary of the invention

The present invention is directed to the deficiencies in the prior art, a kind of door lock swing type dead bolt is provided, make to adopt the door lock of this dead bolt to be arranged on to be left unlocked or unlatched when upper, can reduce the power of pushing, avoid door leaf locking phenomenon, realize the object that easily pushes and come in and go out.

The present invention is achieved by the following technical solutions:

A kind of door lock swing type dead bolt, be arranged on lock body, it comprises tongue body, tongue seat, bearing pin and flexible member, described tongue base device is on described lock body, described tongue body is articulated with on this tongue seat and can be swung around this bearing pin by bearing pin, these tongue body both sides are respectively equipped with front and rear lingual surface, this front and door leaf plane form front bevel angle α, this rear lingual surface and door leaf plane form back bevel angles β, a side place that departs from bearing pin on described tongue seat is provided with the second blind hole, this second blind hole tongue seat is around provided with tongue seat inclined-plane, the vertical plane of this tongue seat inclined-plane and door leaf plane forms tongue seat oblique angle γ, position corresponding with the second blind hole on described tongue body is provided with the first blind hole, described flexible member is arranged in this first blind hole and the second blind hole and described tongue seat and tongue body is pushed to both sides.

Door lock of the present invention swing type dead bolt, 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 °; Described flexible member is cylindrical compression spring.

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

1, the present invention is provided with the flexible member that is offset to hinge pin axle one side between the tongue seat being hinged and tongue body, therefore, when door leaf is promoted from rear side, tongue body just can be promoted by the keeper on doorframe and swing around bearing pin, make the angle of front bevel angle α become large, 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 less αHe back bevel angles, the front bevel angle β that is not more than 45 °, thereby lengthened the length of dead bolt, reach most the more than 1.4 times of common dead bolt, thereby guaranteed the reliable of door leaf location, even if door gap is bigger or when having fitful wind, still can keep door leaf to be left unlocked or unlatched state in reliably.
