Abstract

The utility model provides an aluminum alloy push pull window lock, which comprises a hollow lock shell and a screwed plug and an outer screw respectively arranged at the front and rear end of the hollow shell, and is characterized in that the hollow lock shell is internally equipped orderly from front to back with a lock pin, a socket and a push clamp, the lock pin is provided with a spring arranged between the screw plug and the lock pin back clamp platform; the rear end of the socket has an inserting shaft is in corresponding with the inserting hole of the push clamp front, while the latch of the rear end of the socket is opposite to the latch of the push clamp front in different positions; the inner rear part of the hollow lock shell is provided with sliding slots with different depth opposite to the element rest of the push clamp outside, and the siding slots with different depth are positioned at intervals with the same space, the outside of the socket is provided with an element rest corresponding with the deep sliding slot at the inner rear part of the hollow lock shell. The utility model has advantages that the lock pin and the lock hole of the lock are easy to install on the middle frame of the push pull window, promising perfect concealment, extremely easy installation and firm and reliable locking.

Description

The aluminium alloys sliding window lock

Technical field:

The utility model relates to a kind of lockset, specifically a kind of aluminium alloys sliding window lock.

Background technology:

Present more common on the market aluminium alloys sliding window lock mainly contains the formula of the pulling lock that is installed on the center and the button that is installed on the windowsill locked.The former can see that outside window disguise is relatively poor, if do not lock, cause chance just can for bad person's burglary; And the latter installs relatively effort, also will check whether lock after locking, because should the lock latch hook too small with the locked groove contact area, be difficult for pinning, and safety is lower.

Summary of the invention:

In view of the deficiency that above-mentioned prior art exists, the purpose of this utility model provides the aluminium alloys sliding window lock of better, the easy for installation and easy pinning of a kind of disguise.

The purpose of this utility model is achieved in that it comprises hollow lock housing and the plug and the outer nut of this hollow lock housing rear and front end that is placed in, it is characterized in that: be provided with lock pin, cutting ferrule successively and push away card before and after in hollow lock housing, lock pin is provided with and places the spring that blocks behind plug and the lock pin between the platform; The cutting ferrule rear end is with and is inserted axle and to push away card jack that front end is with corresponding, cutting ferrule rear end institute with teeth with push away the card front end dislocation with teeth relative; The rear portion is provided with and pushes away the chute that the outside institute of card is corresponding with convex tendon and weight differs in hollow lock housing, and the chute equi-spaced apart that this weight differs is discharged, the cutting ferrule outside have with hollow lock housing in the rear portion be with the corresponding convex tendon of dark chute.During use, only need boring a hole on the window center and this lockset can be installed, draw at another and bore one on window center and get final product with the corresponding lockhole of this lockset lock pin once drawing.When two draw the window center to intersect (window is in closure state), window locks can be closed by pushing away card.

The lock pin and the lockhole that the utility model has the advantages that lockset are drawing on the center of window, and better disguised, it is also very convenient, sealed firm to install.

Below in conjunction with accompanying drawing the utility model is done to describe in detail.

Description of drawings:

Fig. 1 is the utility model structural representation;

Fig. 2 is an A-A view among Fig. 1;

Fig. 3 is the cutting ferrule structural representation;

Fig. 4 is Fig. 3 right side view.

The specific embodiment:

By accompanying drawing as can be known, the utility model mainly by lock pin 1, plug 2, hollow lock housing 3, spring 4, cutting ferrule 5, push away card 6 and outer nut 7 constitutes.Plug 2 and outer nut 7 hollow lock housing 3 rear and front ends that are placed in; Lock pin 1, cutting ferrule 5 and push away card 6 front and back and place successively in the hollow lock housing 3, lock pin 1 are provided with and place the spring 4 between the card platform 1-1 behind plug 2 and the lock pin; Cutting ferrule 5 rear ends are with and are inserted axle 5-3 and to push away card 6 jacks that front end is with (indicating among the figure) corresponding, cutting ferrule 5 a rear ends 5-2 with teeth with push away card 6 a front ends 6-1 with teeth and misplace relative; In hollow lock housing 3 rear portion be provided with push away card 6 outside and chute 3-1,3-2 that weight differ corresponding with convex tendon 6-2, the chute equi-spaced apart discharging that this weight differs, cutting ferrule 5 outsides have with hollow lock housing 3 interior rear portions is with the corresponding convex tendon 5-1 of dark chute 3-1.Every promotion pushes away card 6 once, and cutting ferrule 5 rotates (by latch 5-2, the 6-1 decision of dislocation mutually).When cutting ferrule 5 rotates to when being with on it that the rear portion is with dark chute 3-1 corresponding in convex tendon 5-1 and the hollow lock housing 3, in the hollow lock housing 3 of lock pin 1 retraction under the effect of spring 4, this moment, lockset was in open mode; When cutting ferrule 5 rotates to when being with on it that the rear portion is with shallow chute 3-2 corresponding in convex tendon 5-1 and the hollow lock housing 3, cutting ferrule 5 can not after move, with spring 4 compressions, lock pin 1 Shen goes out outside the hollow lock housing 3, this moment, lockset was in closure state.

This lockset also can be installed on the boundary frame area that draws window, is oppositely arranged some lockholes on the window bottom frame drawing of correspondence, makes it to adjust the size of drawing window to open, and regulates ventilation.In that to draw window to open hour sealed, both made family unmanned, the bad person also is difficult in the inlet chamber.
