Abstract

The utility model relates to a door lock, particularly a multi-function theft-proof ball-shaped door lock, and is composed of a bolt, a combined type lock body, a lock head, an indoor ball handle, and an outdoor ball handle. The bolt is a lengthened and is provided with an anti-saw pin which can rotate along the bolt in the axial direction. A bolt tug which is connected with the bolt and synchronously runs is provided with a bump which can lead the bolt to become a movable bolt and a bump which can lead the bolt to be retracted in the lock body. The bolt retraction gear of the utility model can become the movable bolt, and the bolt extension gear can become a fixed bolt. In addition, a lengthening-shaped bolt can be formed. The utility model has the advantages of self locking, anti-saw performance, anti-prying performance, etc.

Description

Multi-function theft-proof ball shaped door lock

The utility model relates to a kind of door lock, the spherical door lock of particularly a kind of multifunctional burglary-resistant.

At present, in civilian door lock field, " department does not make " lock moulding is outmoded, and open and close Men Shiwu handle, its dead bolt are single oblique dead bolt, are easy to cause stolen accident, and its security insurance coefficient is lower; Though another kind of two tongue combined type door lock is not locked security insurance coefficient height than " department makes ", but still has above-mentioned shortcoming.Existing spherical door lock is handsome in appearance, easy to use, but does not have inside and outside chain safeties, and short oblique tongue is crossed the threshold by the sled tongue easily, thereby causes the shortcoming of stolen accident.

The purpose of this utility model is to provide a kind of multifunctional burglary-resistant spherical door lock, makes it both overcome moulding of " department does not make " lock and the defective of using, and has improved the security insurance performance of door lock with knob again.

The technical solution of the utility model is: in the spherical door lock of the multifunctional burglary-resistant that is made of dead bolt, combined type lock body, tapered end, indoor ball handle, outdoor ball handle, its dead bolt is microscler for adding, and be equipped with can be along the anti-saw pin of dead bolt axial rotation.Be connected with dead bolt and the dead bolt of synchronous operation drags to be equipped with on one's body and can make dead bolt become the projection of movable lug and the projection that can make its whole indentation lock bodies.

Be equipped with the tongue spacer that contracts in the lock body, the one end is by pivot pin and lock body and is rotationally connected, and is equipped with torque spring; The other end is equipped with inside and outside runner, and the centre is equipped with the concave surface that drags projection on one's body to match with dead bolt.

Also be equipped with dead bolt limited support sheet in lock body, the one end is by pivot pin and lock body and is rotationally connected, and is equipped with torque spring, also is equipped with the supporting surface that drags projection on one's body to match with dead bolt on dead bolt limited support sheet.

In addition, the utility model also is equipped with windproof tongue on lock body.

According to technique scheme, dead bolt indentation of the present utility model one retaining can become movable lug, and stretching out a retaining can become slow-witted tongue, and forms and add microscler dead bolt, and has characteristics such as self-locking, anti-saw, pick-proof.

The utility model will be further described below in conjunction with drawings and Examples:

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model sectional drawing;

Fig. 3 is that Fig. 2 K is to view.

With reference to Fig. 1, the utility model is made of lock body 17, outdoor ball handle 22, indoor ball handle 9, tapered end 2, dead bolt 8.Indoor and outdoor ball handle is connected with lock body 17 by inside and

outside tail bar

10,3 respectively.The root of ball handle all is equipped with to be decorated toppedly 18, is equipped with button 12 on the indoor ball handle 9.Dead bolt 8 is built-in with anti-saw pin 19, and this anti-saw pin 19 can be along dead bolt 8 axial rotation, when the ruffian steals, be difficult to this cancellation sawed-off, thereby played the burglary insurance effect.Be equipped with tapered end 2 in the outdoor ball handle, key 1 inserted rotate just unlatching, locking door lock in the tapered end 2.

With reference to Fig. 2, dead bolt 8 drags body 6 to be connected with dead bolt, and has torque spring to support.Inside and outside

tail bar

10,3 inserts in the through hole in the middle of the inside and outside

thumb wheel

11,4, and can drive one and play rotation.Dead bolt drag an end of body 6 be equipped with outside pulley 5, be subjected to the effect of outer thumb wheel 4 during work.One end of dead bolt limited support sheet 7 and lock body 17 are and are rotationally connected, and are subjected to the effect of torque spring.On dead bolt limited support sheet 7, also be provided with a supporting surface 20 ', during work, it can be arranged on dead bolt and drag the projection 20 on the body 6 to coincide mutually.Contract end of tongue spacer 13 and lock body 17 is and is rotationally connected, and is subjected to the effect of torque spring.On the tongue spacer 13 that contracts, also be provided with supporting surface 21 ', during work, it can be arranged on the projection 21 that dead bolt drags body 6 and coincide mutually.

Also be equipped with windproof tongue 15 on lock body 17, it is to be dead bolt 8 whole indentation lock bodies 17, establishes and prevent again that Men Buhui from being opened by wind, during use, need not use key and ball handle, only needs manpower open and close get final product, very convenient reliably.

With reference to Fig. 3, lock panel 16 is housed before the combined type lock body 17.

The course of work of the present utility model is as follows:

One, with key open and close door lock

Key 1 is inserted tapered end 2, and outer tail bar 3 is rotated in dextrorotation, and outer tail bar drives outer thumb wheel 4, and outer thumb wheel drives outer pulley 5, and outer pulley promotes dead bolt and drags body 6, and first grade of dead bolt indentation at this moment is spacing in the movable lug position with dead bolt 8 by dead bolt limited support sheet 7.Continue to promote as pulley, second grade of dead bolt indentation is promptly in the whole indentation lock bodies of dead bolt.At this moment door just can be opened.Otherwise key is left-handed, and dead bolt stretches out first grade and is movable lug, and key continues left-handed dead bolt and stretches out second grade, and movable lug becomes slow-witted tongue.Transfer to key this moment, and dead bolt is maintained at the elongated spring bolt position.Simultaneously, indoor ball handle also is maintained at the state that can not rotate.Outdoor after laying the key under the door like this to the indoor function that has played insurance.

Two, with indoor ball handle open and close door lock

With tail bar 10 in the indoor ball handle 9 left-handed rotations, thumb wheel 11 in interior tail bar drives, interior thumb wheel drive the coaxial interior pulley of pulley 5, and interior pulley promotes dead bolt and drags body 6, and first grade of dead bolt indentation is spacing in the movable lug position with dead bolt 8 by dead bolt limited support sheet 7.Continue to promote second grade of whole indentation lock body of dead bolt as interior pulley.Otherwise indoor ball handle dextrorotation dead bolt stretches out first grade and is movable lug.Indoor ball handle continues dextrorotation, and dead bolt stretches out second grade, and movable lug becomes slow-witted tongue.Advance button 12 this moment, and dead bolt is maintained at the elongated spring bolt position, and outdoor key just can't be opened tapered end and cross the threshold, indoor like this to the outdoor function that plays insurance.

In addition, the utility model can and have the whole indentation lock bodies of dead bolt and remains on the function that can not stretch out in the lock body.
