Description
Technical Field
The invention relates to special measures related to doors and windows, in particular to a pull-type telescopic and rotary lock tongue control mechanism.
Background
The lock body is a common hardware fitting and is arranged on a door and window sash. The door and window is responsible for opening and locking the door and window between door and window frame and door and window fan through the lock body. The lock tongue used on the lock body is a core part of the lock body and directly plays roles in opening and locking doors and windows. The lock body lock tongue in the prior art can only do back-and-forth telescopic movement, and the single function of the lock tongue of the structure determines the functions of opening and directly locking the door and the window only to one side. In real life, two sides of a door or window can be opened sometimes, and only the door is closed in a virtual mode, namely the door is not locked, and only the function of preventing wind from blowing is achieved. The prior art bolts do not address this need. To solve this problem, the applicant has further filed a patent on a retractable and rotatable bolt:
referring to fig. 1 to 12, the retractable and rotatable lock tongue includes a housing assembly 2 and a tongue body assembly 1, and is characterized in that: the tongue body assembly 1 comprises a tongue body 11, a telescopic platform 12 and a spring 13, one end of the spring 13 is fixed at the bottom of the shell assembly 2, the other end of the spring 13 is connected with the telescopic platform 12, the tongue body 11 is rotatably arranged on the telescopic platform 12 and stretches along with the telescopic platform 12, rectangular lug bosses 112 are arranged on two sides of the tongue body 11 and matched with the lug bosses 112, a rectangular locking groove 22 is formed in the lock shell 21, and when the bayonet lock 3 is inserted into the locking groove 22, the lug bosses 112 are blocked, so that the tongue body 11 cannot rotate (be locked).
Further:
the tongue 11 has a section of arc-shaped bottom 111, and the arc-shaped bottom 111 contacts with the platform at the top end of the telescopic platform 12, so that the tongue 11 is rotatably placed on the telescopic platform 12.
A groove 113 is arranged in the middle of the bottom of the tongue 11, and the groove 113 is movably clamped on two sides of the telescopic platform 12. Plays a role of mutual limiting.
The two sides of the tongue 11 are provided with limiting posts 114, and the lock shell 21 is provided with limiting edges 25 which are matched with the limiting posts 114. So that the tongue 11 cannot be separated from the lock case 21.
In the first embodiment: the shell assembly 2 comprises a lock shell 21 with an opening at the bottom and a detachable base 24 arranged at the bottom of the lock shell, a boss 241 is arranged on the base 24, one end of the spring 13 is sleeved on the boss 241, and the other end is connected with the telescopic platform 12.
In a second embodiment: the shell assembly 2 comprises a lock shell 21 with an open side surface and a side panel 27 arranged on the side surface of the lock shell, a convex seat 241 is arranged at the bottom of the lock shell 21, one end of the spring 13 is sleeved on the convex seat 241, and the other end of the spring is connected with the telescopic platform 12.
The door and window can be virtually covered and locked, and the door and window can be opened at two sides of the door and window during virtually covering. Can be freely opened in the state that the door and window is closed, namely, the handle or the handle on the door and window can be directly pulled to be opened without the need of a key, a knob and other modes. Can prevent the wind from blowing the door and window open. A bolt can also be inserted to lock the door and window.
However, this application does not give how the bayonet 3 cooperates with the tongue to achieve the above object, which is a drawback. The present application is directed to a mating control mechanism implemented by the above-mentioned patent.
Disclosure of Invention

The door and window can be virtually covered and locked, and the control problem of the telescopic and rotary lock tongue which can open the door and window at two sides of the door and window during virtually covering is solved.
The technical scheme adopted for solving the technical problems is as follows: the utility model provides a scalable and pivoted spring bolt control mechanism of pulling, including lock body shell and scalable and pivoted spring bolt, scalable and pivoted spring bolt includes casing subassembly and tongue body subassembly, tongue body subassembly includes the tongue body, flexible platform and spring, and the bottom of casing subassembly is fixed in to spring one end, and flexible platform is connected to the other end, and the tongue body is rotationally adorned on flexible platform, and flexible along with flexible platform, there is the lug of rectangular shape in tongue body both sides, with the lug matches, has the locking groove of L shape on the left and right sides lock shell of lock shell, blocks behind the locking groove when the cardboard of bayonet lock inserts from the below that makes the tongue body unable rotation, its characterized in that: the lock body shell comprises a first lock body shell of a left half part and a second lock body shell of a right half part, the clamping pin is fork-shaped, the upper part of the clamping pin is two clamping plates, the cross sections of the clamping plates are U-shaped, the lower part of the clamping plates are pull handles, guide grooves are formed in the side edges of the clamping plates, the first pin shaft penetrates through the guide grooves, the clamping pin is movably arranged in the lock body shell, the pull handles extend out of the lock body shell, and the reset spring is elastically connected with the clamping pin and the lock body shell.
When no external force acts, the elastic force of the return spring enables the clamping plates of the two clamping pins to be respectively inserted into the locking grooves at two sides of the lock shell, so that the tongue body cannot rotate, and the tongue body is in a locking state. When the pull handle of the lower bayonet lock overcomes the elasticity of the return spring, the clamping plates of the two bayonet lock are separated from the respective locking grooves, and the tongue body can rotate to be in an open state.
The beneficial effects of the invention are as follows: the door and window can be opened and closed by the telescopic and rotary lock tongue, and both sides of the door and window can be opened when the door and window is virtually covered and closed.
