Description

Built-in lock for pull door or window

This utility model belongs to lock technology field.

Known to the inventor, the pull-type door and window of present real abdomen generally uses padlock or simple and easy built-in lock, and is outside the lock bridge of padlock is exposed to, not only dangerous but also bother, also not attractive in appearance during use; The pulling force of simple and easy built-in lock concentrates on the panel, causes panel flexible, causes lock malfunctioning; The built-in lock that uses on the pull-type door and window except that it can not be applied to real abdomen door and window, also has only a guide pillar and a Ka Liang on the structure on an empty stomach, and the carrying pulling force is little, and the i.e. lock of closing the door, and uses inconvenience.

The purpose of this utility model is to provide a kind of collection built-in lock, and the padlock advantage is safe in utilization in one, and pull-type easily door and window built-in lock is to overcome the shortcoming of above-mentioned lock.

The utility model is achieved in that

On the basis of original simple and easy pull-type built-in lock in conjunction with pad lock structure, guide pillar and guide pillar spring, U-shaped Ka Liang, double-pin and dog chart have been increased, and make the structural change of original structural frame, lock body, lock core, screw, supported hole are arranged on the structural frame, lead on the lock body and ask hole, Ka Liang hole, biasing post, stopper slot are arranged, to adapt to the needs of use on the lock core.

Because pin is a double-pin, tension can reach 300kg, and is survivable; Two legs of U-shaped Ka Liang enter in the Ka Liang hole when locking fully, can prevent to be sawed beam; Because the effect of guide pillar and guide pillar spring makes lock body draw by not locking when pull-type door and window is closed, lock body is pressed into the i.e. advantage of lock, and is easy to use.Because the panel middle part is stressed, two ends are supported by screw, overcome the middle part distortion.

Reach the structure and the course of work thereof that embodiment describes the built-in lock that forms in conjunction with the utility model in detail in conjunction with the accompanying drawings.

Accompanying drawing 1 is a structural representation of the present utility model.

The following describes embodiment:

Pull-type door and window built-in lock is made of structural frame 1, panel 3, guide pillar 4, U-shaped card beam 5, double-pin 6, dog chart 7, guide pillar spring 8, lock body 10, lock core 11, pellet shot from a slingshot member 15 that structure is identical.Wherein guide pillar and guide pillar spring, U-shaped Ka Liang, double-pin, dog chart are new parts; Structural frame, the structure of lock body and lock core has improvement, and panel and pellet shot from a slingshot member are with originally basic identical.Screw 2 fixed panels are arranged on the structural frame, have supported hole 12 to support lock body, structural frame is fixed on the door (or window), and lock body places in the structural frame, has on it to lead to ask that hole 9, Ka Liang hole 16 enter to guarantee the correspondence position of lock body and U-shaped Ka Liang guide pillar; Lock core places in the lock body, its front end has two biasing posts 13 and double-pin to articulate, there is stopper slot 14 side, the rotational angle of restriction lock core, and guide pillar 4 is positioned on the panel, guide pillar spring 8 places in the pilot hole of lock body, because its effect makes pull-type door (window) when closing, lock body is not in the lock state, when needing locking, promote lock body, make its compression guide pillar spring, lock body moves forward, pin is compressed, lock body continues to move forward, after putting in place, under the dog chart effect, pin blocks Ka Liang, reaches lock-out state.Pin is a cylinder, front end has an inclined-plane, the breach of inclined-plane and U-shaped card beam two leg front portions matched when pin stretched out, place dog chart in the semicircle orifice on the pin, articulate with biasing post respectively by double-pin breach radially, two pin configuration are identical, and placement direction is opposite, lock core clockwise rotates when putting in place, pin compression dog chart.Get back to the shape position of unblanking, otherwise pin produces rightabout power under the dog chart effect, pin is moved round about, drive lock core simultaneously and be rotated counterclockwise, under the stopper slot effect, it is put in place stop, making double-pin reach claimed condition.The two leg tops of U-shaped Ka Liang are cone, make it enter lock body smoothly.The bottom of Ka Liang is fixed on door (or window) frame.

This utility model is widely used on the pull-type door and window of real abdomen.
