Description

A kind of closedown structure

Technical field

The utility model relates to a kind of locking lockset.

Background technology

Locking has a lot of superior parts, particularly security performance good, and it is with good crashproof, pick-proof, anti-plug performance and more and more be widely used.Traditional closedown structure mostly can not promptly locked a door in that door is pent like common safe-guard door lock at closing time like that simultaneously synchronously, and it can only be after shutting up the door carefully earlier, with key dead bolt is ejected and with door locked, therefore traditional locking is cumbersome in use again; Though have the locking that need not use key to lock a door at closing time on the market, the complex structure of this class locking, volume is bigger.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provide a kind of simple in structure, volume is little and the locking that need not can lock a door with key.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of closedown structure, comprise tapered end, dead bolt assembly that is connected with tapered end and the knob assembly that is connected with the dead bolt assembly, the tapered end circle is installed on the described tapered end, one end of tapered end circle is equipped with space washer, space washer is encapsulated in tapered end in the tapered end circle, sword iron is installed on the tapered end, sword iron is connected with knob assembly with the dead bolt assembly respectively, it is characterized in that described sword iron can rotate to an angle on tapered end, in the tapered end circle back-moving spring is installed, rotating spring bearer plate is installed on the back-moving spring, spring bearer plate is provided with the column of compressible spring, on tapered end, be set with and dial peach, dialling peach can rotate and drive sword iron and rotate with it on tapered end, space washer is provided with the arcuate socket that the peach anglec of rotation is dialled in restriction, the rotating locking knob of going out is installed on the tapered end circle, the locking knob of going out is provided with positioning stud, one end of positioning stud interts on spring bearer plate, the other end interts in the arcuate socket on space washer, when going out the locking knob, positioning stud can drive spring bearer plate and dial peach and rotate.

As the utility model improvement of the technical scheme, described space washer is provided with the anti-drilling sheet that contacts with spring bearer plate.

Dead bolt assembly described in the utility model comprises dead bolt, the lock bolt sleeve of dead bolt is installed and drives the shift fork that dead bolt moves that described sword iron interts in shift fork and can drive the shift fork rotation.

Knob assembly described in the utility model comprises backstop, be installed in the backstop and the knob core that is connected with sword iron and be fixedly mounted on knob on the knob core.

The beneficial effects of the utility model are: the utility model can be by being rotatably installed in that the locking knob of going out on the tapered end circle ejects dead bolt and with door locked, and need not use key, so easy to use; And simple in structure, volume is little, and properties of product are stable.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is an assembling schematic diagram of the present utility model;

Fig. 2 is the structural representation that removes back cover portion;

Fig. 3 is a perspective exploded view of the present utility model.

The specific embodiment

With reference to Fig. 1, Fig. 2, the disclosed a kind of closedown structure of the utility model, dead bolt assembly 2 that comprise tapered end 1, is connected with tapered end 1 and the knob assembly that is connected with dead bolt assembly 2, tapered end 1, dead bolt assembly 2 and knob assembly are assembled on the body by fixed connecting piece during installation.Tapered end circle 3 is installed on tapered end 1, one end of tapered end circle 3 is equipped with space washer 4, and space washer 4 is encapsulated in tapered end 1 in the tapered end circle 3, and sword iron 5 is installed on tapered end 1, sword iron 5 is connected with knob assembly with dead bolt assembly 2 respectively, rotates the dead bolt action that sword iron 5 can drive the dead bolt assembly.

With reference to Fig. 3, wherein dead bolt assembly 2 comprises dead bolt 21, lock bolt sleeve 22 and shift fork, and dead bolt 21 is installed in the lock bolt sleeve 22 and can slides in lock bolt sleeve 22, and shift fork is installed in an end of lock bolt sleeve 22, can drive the dead bolt action when shift fork rotates, sword iron interts in shift fork and can drive the shift fork rotation.

Knob assembly comprises backstop 6, be installed in the backstop 6 and the knob core 7 that is connected with sword iron 5 and be fixedly mounted on knob 8 on the knob core 7, one end of sword iron 5 is fixedlyed connected with knob core 7, when driving the rotation of knob core by knob, the knob core can drive sword iron and rotate, and then drives the dead bolt action of dead bolt assembly.

Sword iron 5 can rotate to an angle on tapered end 1, back-moving spring 9 is installed in tapered end circle 3, back-moving spring 9 upper spring pressing plates 10, spring bearer plate 10 can rotate in tapered end circle 3, and spring bearer plate 10 is provided with column 11, when spring bearer plate 10 rotates, column 11 compressible back-moving springs 9, space washer 4 is provided with the anti-drilling sheet 12 that contacts with spring bearer plate 10, and anti-drilling sheet 12 can keep the stability of rotation of spring bearer plate 10, swells in the process of being compressed to prevent back-moving spring 9.On tapered end 1, be set with and dial peach 13, dial peach 13 and can on tapered end 1, rotate and drive sword iron 5 with its rotation, space washer 4 is provided with arcuate socket 14, arcuate socket 14 can limit the anglec of rotation of dialling peach 13, the rotating locking knob 15 of going out is installed on tapered end circle 3, the locking knob 15 of going out is provided with positioning stud 16, one end of positioning stud 16 interts on spring bearer plate 10, the other end interts in the arcuate socket 14 on space washer 4, when the locking knob 15 of going out rotated, positioning stud 16 can drive spring bearer plate 10 and dial peach 13 and rotate.
