Abstract

The utility model relates to a door lock which can lock and proof wind. The wind proof function of the wind-proof door lock is achieved by a wind proof device, wherein, the wind proof device comprises a guide body arranged on a lock catch box and a composite body lock bolt composed of a curved surface-shaped rolling body and a square lock bolt. When the door lock in an opened state, the curved surface of the rolling body is still contacted with the lock catch box, which leads the door lock to be in a pre-opened state, and the door lock can be freely opened under certain exogenic action, so that the favorable function of wind proof is achieved. At the same time, the guide body which can form a curved surface shape or an inclined plane shape is arranged on the lock catch box, which causes the lock bolt to be easily pressed in the lock catch box.

Description

Wind-proof door lock

The utility model is a kind of door lock, it relate to a kind of can locking, windproof door lock.

In the prior art, do not see the like products involved as yet with the utility model.Door lock generally is made of several parts such as keeper, release and lock housings.The dead bolt of conventional door lock all adopts inclined plane shape, need not the external force effect need only arranged with key operated at closing time like this, and dead bolt is easy to enter keeper and door lock is closed, and is easy to use.But there is not wind-shielding function, still not ideal enough.

The purpose of this utility model just is to overcome the shortcoming that existing door lock exists, and proposes a kind of can locking a door, door lock design scheme that again can be windproof.

The purpose of this utility model is achieved in that and is provided with wind-proof device on lock body, this device comprises: guide way on the keeper and the complex dead bolt that is made of curved surface shaped rolling element and dead bolt, when door lock place opening, the rolling element curved surface still contacts with keeper, forms one " family of power and influence ".

Because the species complex dead bolt of dead bolt of the present utility model for being made of curved surface shaped rolling element and square dead bolt, when door lock was in locking states, dead bolt was fastened by keeper, needed could open with key.When door lock is in opening, because rolling element still contacts with keeper, form one " family of power and influence ", make door lock be in a kind of " the accurate unlatching " state, only under a certain size external force effect, door lock could freely be opened, therefore, this door lock still has " locking " ability after unlatching, play good windbreak function.And the guide way on the keeper makes when closing the rolling element motion flexibly, and noise is very little.

Further set forth enforcement of the present utility model below in conjunction with accompanying drawing.

Fig. 1 is the utility model generalized section.

Fig. 2 is the utility model schematic top plan view.

Fig. 3 is the utility model keeper sectional drawing.

As shown in the figure, embed a rotatable curved body 3 in notch of processing and constitute complex dead bolt 4 on common square dead bolt 2, curved surface forms rolling element 3 available metals or engineering plastics are made cydariform, cylindricality or sphere, is cylindricality in this example.Dead bolt drag body 5 to link to each other with complex dead bolt 4 and with latch bolt spring 6, bumper bar 7 contacts; Spring 6 is protected spring base 7, and releasing plate 8 and knob 9 constitute release; and drive releases by knob 9 and make complex dead bolt 4 be in two kinds of states: state one: square dead bolt 2 stretches out lock housing 1, and when being in this shape, the dead bolt plane contacts with keeper 10; door is needed to open Kai with key by locking.State two: square dead bolt 2 retraction lock housings 1, when being in this state, the surface of rolling contacts with keeper 10, because contact surface is a curved surface, contact surface produces one less than 90 ℃ pressure angle, thereby produce the component on the dead bolt direction of motion, the size of this component depends on the motive force on the door, when component during greater than dead bolt elastic force, door is promptly by open, and (for example 5 grades) component is less than latch bolt spring power during less than certain value when wind scale, and door is closed, and opener's motive force can be opened greater than certain value (for example strong breeze power) door, has therefore realized wind-shielding function.In order to make complex dead bolt 4 can conveniently be pressed into keeper 10, therefore on keeper 10, be provided with guide way 11, this guide way can be curved body, also can be clinohedral, as 11 being depicted as clinohedral among the figure

When guide way 11 is bent body, can be fixing cydariform again or it cuts body ", cylindricality or its " cut body ", spherical or its " cut body " and also can be rotating cydariform, cylindricality, spherical.
