Description

The alumium alloy door and window automatic locking

The utility model belongs to the fastening means of push-pull door, window.

The novel aluminum alloy section bar that is used to make plug-type Frame for door and window of Chu Xianing in the market, its shape, size are with traditional different, its position of installing for lock is narrower, traditional aluminium alloy door's sash lock, what have is loaded on this new section bar because of its profile broad discomfort, though the size that has is fit to, and need pull latch fitting when it is locked, use inconvenient.

The purpose of this utility model provides the alumium alloy door and window automatic locking that a kind of profile width can be done less, simple in structure, easy to usely.

The purpose of this utility model is to adopt following measure to realize.

The utility model is made up of lock 1 and snap close 2, described lock 1 by lock 3, pull handle 4, the pin 5 and spring 6 form, the epimere of pulling handle 4 is extruded with a dead bolt with oblique lingual surface vertical with pulling handle handle body, pulling handle 4 places lock 3 vallecular cavities and is hinged and forms lever with pin 5, spring 6 places lock 3 vallecular cavities, it pulls handle 4 hypomeres corresponding to what dead bolt was suppressing the balance pivot other end, makes to pull handle 4 epimeres and be resisted against on the lock 3, and dead bolt protrudes in outside the lock 3 vallecular cavities bottom.

Can protrude in the outer bolt periphery in lock 3 vallecular cavities bottoms, be provided with lock 3 is connected as a single entity and protect frame 7, after locking, but the dead bolt dropout is rocked and prevented in the front and back of protecting frame 7 restraint doors, window.

The snap portion part that interlocks with dead bolt on the snap close 2 is a ring-type, also can be hook-shaped.

During use, lock 1 and snap close 2 are installed in respectively on dodge gate (window) frame and fixed gate (window) frame, when dodge gate (window) is pushed to snap close 2 places, snap close 2 is collided and the jack-up dead bolt with the oblique lingual surface of dead bolt of lock 1, after dead bolt is crossed in snap close 2 front portions, spring 6 resets dead bolt by the leverage of pulling handle 4, and snap close 2 interlocks with dead bolt, and automatic locking just locks.When opening the door (window), fasten with finger and to pull handle 4 upper ends and outwards pull, dead bolt is thrown off snap close 2, at this moment just can draw back dodge gate (window), and finger is decontroled, and dead bolt resets under spring 6 effects.

With the phase-locked comparison of traditional alumium alloy door and window, the utility model is simple in structure and sturdy and durable, and is not fragile; Can automatically lock when closing the doors and windows, easy to use; The design that lever is pulled handle can make the utility model profile width can do lessly and have enough surely intensity, is not only applicable to lock the narrower novel section bar in installation site, also is adapted at using on traditional aluminium alloy door's window profile simultaneously.

Be described further below in conjunction with the embodiment accompanying drawing.

Fig. 1 is that embodiment locks the front view with snap close;

Fig. 2 is the left view that Fig. 1 locks;

Fig. 3 is the stereogram of embodiment snap close;

Fig. 4 is the stereogram that embodiment pulls handle;

Fig. 5 is that the A-A that locks of Fig. 1 is to sectional view;

Fig. 6 pulls the structural representation that handle is locked when cocked;

Fig. 7 is the schematic diagram of the oblique lingual surface of snap close jack-up dead bolt;

Fig. 8 is the schematic diagram of automatic locking locking;

Fig. 9 is the schematic diagram that automatic locking is threaded off.

The alumium alloy door and window automatic locking is made up of lock 1 and snap close 2.Snap close 2 is rectangular ring with lock 1 snap portion part that interlocks 201.The lock 1 by lock 3, pull handle 4, the pin 5 and spring 6 form, lock 3 usefulness Zn-base alloy injection mouldings form, and have vallecular cavity 301.The cross section of pulling handle 4 is a rectangle, and its epimere is extruded with a dead bolt 401 vertical with pulling handle handle body, and dead bolt 4 has an oblique lingual surface 402, pulls handle 4 upper ends 403 and is skewed and is shaped on anti-skidding asperities.Pull handle 4 and place lock groove 301 and hinged with pin 5 and lock 3, lock vallecular cavity 301 leaves a room 302 above pulling handle 4, be used to stretch into finger and remove to pull handle 4, spring 6 places on the positioning seat 303 of lock vallecular cavity bottom protrusion, suppressing the hypomere of pulling handle 4, the epimere of pulling handle 4 is resisted against on the lock vallecular cavity bottom 304.Dead bolt 401 is outstanding from lock vallecular cavity bottom opening, is with one outside it and protects frame 7, protects frame 7 and makes for one with lock 3.

Above-mentioned illustrated lock 1 is applicable to the occasion that snap close 2 interlocks with it from the left side, makes position with above-mentioned diagram symmetry into if will pull dead bolt 401 on the handle, and then the lock of being formed just is applicable to the occasion that snap close interlocks with it from the right side.
