Description

The automatic blocking device that door and window is used

The utility model relates to the device that can be used for making the door and window automatic blocking.

Door and window is had by the locking device of locking and unlatching automatically and easily much reported, some is come into operation.Though its concrete form of structure is not quite similar, principle all is made up of the latch hook two-part structure that can be subjected to fasten manual snap close with it cooperation together in lock body, and handle wherein and the general member that all adopts the monolithic devices that is connected as a single entity of snap close.In a single day though it can have certain advantage in some cases, the structure of some this monolithic devices member is comparatively complicated, has brought certain difficulty for processing and assembling, and has damaged also and can only integrally have been changed, its inconvenience and disadvantage are arranged.

The purpose of this utility model is at above-mentioned situation, and the automatic blocking device that provides a kind of door and window that adopts the split combining form to constitute to use makes its production and processing and assembling and maintain and replace all convenient.

Door and window of the present utility model automatic blocking device does not change the basic structure principle of existing this class locking device, promptly still the manual snap close and the latch hook two-part structure that can fasten cooperation is with it formed by can being subjected in the lock body.Wherein on the lock body seat, has a groove that has a opening that can ccontaining handle.An end that is connected in the handlebody on the lock body seat through hinge is a pushing end, and the other end be for can be positioned at the handle at this slot opening place of lock body seat, and is provided with the elastic construction of the usefulness that resets between handlebody and lock body seat, as elastic components such as torsion spring commonly used, extension springs.Place, evagination bottom at this lock body seat groove is provided with free bearing, be connected with locked body through hinge, one end of locked body has and can bump the bonnet lock hole that the latch hook that cooperates the inclined-plane fastens mutually with having the top, and the other end has to lean to cooperate with the pushing end of handlebody and leans the inclined-plane.Between locked body and lock body seat and be combined with this that can make said locked body and lean the elastic components such as torsion spring, extension spring or stage clip that the inclined-plane can be all the time keeps in touch with this pushing end of handlebody.

Below with example shown in the drawings foregoing of the present utility model is described further.But this should be interpreted as that the scope of the above-mentioned theme of the utility model only limits to following example.

Fig. 1 is the structural representation of the utility model locking device.

Fig. 2 is the A-A structure chart of Fig. 1.

Fig. 3 is the schematic construction of Fig. 1 device when being in opening.

This door and window as shown in the figure automatic blocking device is formed the manual snap close and the latch hook two-part structure that can fasten cooperation with it by can being subjected in the lock body.Wherein has a groove 2 that has opening that can ccontaining handle 4 on the lock body seat 1.An end that is connected in the handlebody 6 on the lock body seat 1 through hinge 5 is a pushing end 7, and the other end is for being positioned at the handle 4 of these groove 2 opening parts of lock body seat.1 of handlebody 6 and lock body seat are provided with the extension spring or the torsion spring 3 of the usefulness that resets.Place, evagination bottom at lock body seat groove 2 is provided with free bearing 12, is hinged through hinge 10 and locked body 9.One end of locked body 9 has and can make to fasten mutually the bonnet lock hole 11 that cooperate with latch hook 13, and the other end has to lean to cooperate with the pushing end 7 of handlebody and leans inclined-plane 8.1 of locked body 9 and lock body seat also are combined with this that can make said locked body 9 and lean elastic components 14 such as the torsion spring that can be all the time keeps in touch with handlebody pushing end 7 on inclined-plane 8 or stage clip.

During use, handle 4 places by pulling handle body 6 in the groove 2 of lock body seat 1, handlebody is rotated around hinge 5, its pushing end 7 can promote locked body 9 also around hinge 10 rotations along the inclined-plane 8 that leans of locked body 9, bonnet lock hole 11 on the locked body just can be removed the state that fastens mutually with latch hook 13, door and window can be opened, and its state as shown in Figure 3.When closing the doors and windows, lock body is closed and is moved to the latch hook direction with door and window, after the top that contacts latch hook 13 when the end at bonnet lock hole 11 places of locked body is bumped and is cooperated the inclined-plane, locked body can be rotated around hinge 10 by the roof pressure of latch hook 13 automatically, bonnet lock hole 11 is entered with the fastening of latch hook 13 cooperate the position, the door and window locking is lived.Elastic component 3 that matches with handlebody 6 and the elastic component 14 that matches with locked body 9 can make handlebody 6 and locked body 9 can remain as shown in Figure 1 basic status.This shows that the structure of the utility model locking device is very simple, stable working state is reliable, and because locked body and handlebody are split type structural member, to production and processing, and assembling, maintenance and replacing parts have all brought very big convenience.
