Description

The scalable lock tongue control mechanism with rotation of extending type

Technical field

The present invention relates to special measures related with door and window, are related to lock tongue, espespecially a kind of extending type it is scalable and rotation Lock tongue control mechanism.

Background technology

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 actual 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 windproof effect 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, described a kind of scalable and rotation lock tongue, including housing unit 2 and tongue body component 1, It is 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 rotationally loaded on scaling platform 12, flexible with scaling platform 12, There are the ear of oblong-shaped convex 112 in 11 both sides of the 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, prevents tongue body 11 from rotating (locking).

Further：

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

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

There are limited post 114 in 11 both sides of the tongue body, have position-limited edge 25 to be adapted with the limited post 114 in lock housing 21.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, one end of the spring 13 to be placed in projection seat 241 on the pedestal 24, other end connection Scaling platform 12.

In a second embodiment：The lock housing 21 of the housing unit 2 including lateral opening and loaded on the lock housing side Side panel 27,21 bottom of the lock housing have projection seat 241, one end of the spring 13 to be 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 need not 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 coordinate to reach object above with lock tongue, this is its disadvantage.The application It is the mating control mechanism for above-mentioned patent working.

Invention content

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

The technical solution adopted by the present invention to solve the technical problems is：The lock that a kind of extending type is scalable and rotates is provided Tongue control mechanism, including lock body shell and scalable and rotation lock tongue, described scalable and rotation lock tongue includes housing unit With tongue body component, the tongue body component includes tongue body, scaling platform and spring, and spring one end is fixed on the bottom of housing unit, The other end connects scaling platform, and tongue body is rotationally loaded on scaling platform, and flexible with scaling platform, there are length in the tongue body both sides The ear of square shape is convex, with the convex matching of the ear, has L-shaped locking groove in the left and right face lock housing of lock housing, when bayonet lock snap-gauge from Blocking ear is convex after locking groove is inserted into lower section, prevents tongue body from rotating, it is characterised in that：The lock body shell includes the lock body of left side The lock body shell two of shell one and right side, the bayonet lock are in fork-shaped, and top is two snap-gauges, and cross section takes the shape of the letter U, and lower part is to draw Handle, snap-gauge side have guide groove, the first axis pin to pass through the guide groove, bayonet lock are made movably to be loaded in lock body shell, and pull handle stretches out Outside lock body shell, resetting spring elastic connection bayonet lock and lock body shell.

When without outer force effect, the elastic force of resetting spring makes the snap-gauge of two bayonet locks be inserted into the locking groove on lock housing both sides respectively, makes Tongue body cannot rotate, and tongue body is in blocking.When the pull handle for pulling down bayonet lock overcomes the elastic force of resetting spring, make two bayonet locks Snap-gauge is detached from respective locking groove, and tongue body can rotate, and is in open state.

The beneficial effects of the invention are as follows：It solves the control problem that scalable and rotation lock tongue is opened and is latched, makes 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.
