Description

The control mechanism of ejecting type rotatable flexible 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 ejecting type rotatable flexible lock tongue Control mechanism.

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.To solve this In addition problem, the applicant have applied for patent with regard to scalable and rotation lock tongue:

Referring to attached drawing 1~12, the scalable lock tongue with rotation of described one kind, including housing unit 2 and tongue body component 1, Be characterized in that: the tongue body component 1 includes tongue body 11, scaling platform 12 and spring 13, and housing unit 2 is fixed in 13 one end of spring Bottom, the other end connects scaling platform 12, and tongue body 11 is flexible with scaling platform 12 rotationally loaded on scaling platform 12, 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 in lock housing 21 Slot 22 stops 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).

Further:

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: the lock housing 21 of the housing unit 2 including bottom opening and loaded on the lock housing bottom Detachable pedestal 24 has projection seat 241 on the pedestal 24, and one end of the spring 13 is placed in projection seat 241, other end connection Scaling platform 12.

In a second embodiment: the housing unit 2 include side opening lock housing 21 and loaded on the lock housing side Projection seat 241 is arranged at side panel 27,21 bottom of lock housing, and one end of the spring 13 is placed in projection seat 241, and other end connection is flexible Platform 12.

The patent solve door and window not only and can be left unlocked or unlatched but also can locking, can asking opening of doors and windows on the both sides of door and window when being left unlocked or unlatched Topic.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 can be opened, and not need to lock The modes such as spoon, turn-knob are opened.It can prevent wind from blowing door and window open.Bolt can also be inserted by door and window locking.

But this application does not provide bayonet lock 3 is how to cooperate to reach object above with lock tongue, this is its disadvantage.The application It is the mating control mechanism for above-mentioned patent working.

Summary of the invention

For the missing and needs of the prior art, the purpose of the present invention is to provide a kind of ejecting type rotatable flexible lock tongues Control mechanism.Aim to solve the problem that door and window not only and can be left unlocked or unlatched but can locking, when being left unlocked or unlatched the both sides of door and window can by opening of doors and windows can The control problem of flexible and rotation lock tongue.

The technical solution adopted by the present invention to solve the technical problems is: providing a kind of ejecting type rotatable flexible lock tongue Control mechanism, including lock body shell, scalable and rotation lock tongue and control mechanism, described scalable and rotation lock tongue includes shell Body component and tongue body component, the tongue body component includes tongue body, scaling platform and spring, and spring one end is fixed on housing unit Bottom, the other end connect scaling platform, and tongue body is rotationally loaded on scaling platform, flexible with scaling platform, the tongue body two Side has the ear of oblong-shaped convex, with the convex matching of the ear, there is rectangular locking groove in lock housing, after bayonet lock is inserted into locking groove Stop ear convex, is able to rotate tongue body not, it is characterised in that: the lock body shell includes the lock body shell one of left side and the lock of right side Body shell two, the control mechanism include press component and two bayonet locks, and two bayonet locks are loaded on tongue body component two sides, and respectively It is respectively rotationally loaded in shell by the second shaft, upper part has snap-gauge and locking groove to match, and can inject tongue in locking groove Body locking, two bayonet locks are connected by first rotating shaft, wherein being equipped with reset spring, reset spring in the second shaft of a bayonet lock Two bayonet locks of elastic connection, the press component movably push up convex, the convex apical grafting in top wherein one loaded on having in lock body thereon Bayonet lock.

When without external force, the torsion of reset spring makes the snap-gauge of bayonet lock be inserted into locking groove, and tongue body is not able to rotate, and makes tongue body In blocking.When by the convex torsion for overcoming reset spring that bears down on one, making the snap-gauge of bayonet lock be detached from locking groove, tongue body can turn It is dynamic, it is in the open state.

The beneficial effects of the present invention are: solving the control problem that scalable and rotation lock tongue is opened and is latched, make door Window can not only be left unlocked or unlatched but also can locking, can be by opening of doors and windows on the both sides of door and window when being left unlocked or unlatched.
