Description

Scalable and rotation lock tongue

Technical field

The present invention relates to special measures related with door and window, are related to lock tongue, espespecially a kind of scalable and rotation lock tongue.

Background technique

Lock body is a kind of common Hardware fitting, is installed in door and window fan.Door and window by lock body sash and door and window fan it Between be responsible for door and window open and lock.The lock tongue used on lock body is its core part, directly plays the unlatching and locking of door and window Effect.The lock body lock tongue of the prior art can only make elastic movement, and the lock tongue simple function of this structure determines that door and window can only It is opened and direct locking functions toward one side.In real life, we need the both sides of door and window that can open sometimes, only door void It closes, i.e., door is not latched, and only serves the effect that radix saposhnikoviae is blown open.The lock tongue of the prior art cannot be applicable in this demand.

Summary of the invention

In view of the shortcomings of the prior art, the purpose of the present invention is to provide a kind of scalable and rotation lock tongues.It is intended to solve Certainly door and window can not only be left unlocked or unlatched but also can locking, when being left unlocked or unlatched the problem of the both sides of door and window can be by opening of doors and windows.

The technical solution adopted by the present invention to solve the technical problems is: providing a kind of scalable and rotation lock tongue, packet Include housing unit and tongue body component, it is characterised in that: the tongue body component includes tongue body, scaling platform and spring, spring one end It is fixed on the bottom of housing unit, the other end connects scaling platform, and tongue body is rotationally loaded on scaling platform, with scaling platform Flexible, the tongue body two sides have the ear of oblong-shaped convex, with the convex matching of the ear, there is rectangular locking groove in lock housing, when Bayonet lock stops ear convex after being inserted into locking groove, and tongue body is made not to be able to rotate (locking).

The tongue body has one section of arcuate bottom, and the plane contact of the arcuate bottom and scaling platform top can be rotated tongue body Ground is placed on scaling platform.

Fluted among the tongue body bottom, the groove is stuck in the two sides of scaling platform.Play the role of mutually limiting.

There are limited post in the tongue body two sides, have position-limited edge to be adapted in lock housing with the limited post.Prevent tongue body from being detached from Lock housing.

Further:

The housing unit can be the lock housing including bottom opening and the detachable pedestal loaded on the lock housing bottom, There is projection seat on the pedestal, one end of the spring is placed in projection seat, and the other end connects scaling platform.

The housing unit can also be the lock housing for including side opening and side panel loaded on the lock housing side, described Projection seat is arranged at lock housing bottom, and one end of the spring is placed in projection seat, and the other end connects scaling platform.

There is projection seat on the pedestal, one end of the spring is placed on outside projection seat.Fixed function is risen to spring.

The beneficial effects of the present invention are: solve door and window not only and can be left unlocked or unlatched but can locking, on the both sides of door and window when being left unlocked or unlatched The problem of by opening of doors and windows.It can freely be opened in the state that door and window is closed, i.e., the handle or knob on direct sliding door and window are just It can open, not need the modes such as key, turn-knob and open.It can prevent wind from blowing door and window open.Bolt can also be inserted into close door lock.

Specific embodiment

Referring to attached drawing, a kind of scalable and rotation the lock tongue of the present invention, including housing unit 2 and tongue body component 1, feature Be: the tongue body component 1 includes tongue body 11, scaling platform 12 and spring 13, and the bottom of housing unit 2 is fixed in 13 one end of spring Portion, the other end connect scaling platform 12, and tongue body 11 rotationally loaded on scaling platform 12, stretches with scaling platform 12, described There are the ear of oblong-shaped convex 112 in 11 two sides of tongue body, match with the ear convex 112, there is rectangular locking groove 22 in lock housing 21, Stop ear convex 112 after bayonet lock 3 is inserted into locking groove 22, tongue body 11 is made not to be able to rotate (locking).

In an embodiment of the present invention:

The tongue body 11 has one section of arcuate bottom 111, and the contact with platform of the arcuate bottom 111 and 12 top of scaling platform makes Tongue body 11 is rotationally placed on scaling platform 12.

Fluted 113 among 11 bottom of tongue body, the groove 113 is movably stuck in the two sides of scaling platform 12.It rises To the effect mutually limited.

There are limited post 114 in 11 two sides of tongue body, have position-limited edge 25 to be adapted in lock housing 21 with the limited post 114.Make Tongue body 11 cannot be detached from lock housing 21.

In the first embodiment of the present invention: the lock housing 21 of the housing unit 2 including bottom opening and being loaded on the lock The detachable pedestal 24 of shell bottom has projection seat 241 on the pedestal 24, and one end of the spring 13 is placed in projection seat 241, separately One end connects scaling platform 12.

In the second embodiment of the present invention: the housing unit 2 include side opening lock housing 21 and be loaded on the lock Projection seat 241 is arranged at the side panel 27 in shell-side face, 21 bottom of lock housing, and one end of the spring 13 is placed in projection seat 241, the other end Connect scaling platform 12.

When use:, can be under non-locking states due to the rotatability of lock tongue after lock tongue is installed to door and window fan Handle or knob (referring to Fig. 5 Fig. 6 Fig. 7), i.e., on direct sliding door and window can be freely opened when door and window closing to be opened, and do not needed The modes such as key, turn-knob are opened.And door and window is under closing (not being locking) state, because having certain resistance when lock tongue rotation, So can prevent wind from blowing door and window open.Tongue body 11 is able to rotate not when bayonet lock 3 is inserted into locking groove 22, and locking is played to door and window and is made With (referring to Figure 11).

Lock housing 21 of the invention has bottom opening (see Fig. 4) and side opening (see Figure 12) two kinds of forms.
