Built-in type lifting sliding door lock

Abstract

The invention belongs to the technical field of building door and window transmissions, and particularly relates to a built-in type lifting sliding door lock which comprises a lock point linking mechanism and a lock base. The built-in type lifting sliding door lock is characterized in that the lock base is of a flat plate structure which is conveniently embedded into a section bar, wherein a mainbody of the lock base is equipped with a guide-in slot and a lock slot which communicate with each other in sequence; and the lock point linking mechanism comprises a lock point, a slide plate, a fixed plate, a pulling sheet A, a pulling sheet B, a connecting sheet and a cam. The built-in type lifting sliding door lock has the beneficial effects that: displacement changes of the lock point are converted into rotation changes of the cam, damping is converted, flexibility and convenience are achieved, and hand feeling comfort is strengthened; the structure is delicate, and is properly simplified, a fault rate is reduced by a connecting way of parts, and the service life is long; through the built-in structural features, the lock point is conveniently mounted inside a door leaf, and a lock base flat plate is conveniently embedded into a door frame as a result of a flat structure, so that phenomena such as collision when the children get in and out and clothes hooking when the adults get in and out are reduced; and moreover, the built-in type lifting sliding door lock is elegant in appearance and is safe to use.

Description

technical field [0001] The invention belongs to the technical field of building door and window actuators, in particular to a lifting type built-in sliding door lock. Background technique [0002] At present, the lifting and sliding door locks used in buildings are all fixed on the door frame abruptly. When children enter and exit, they are easy to bump and cause injuries, and adults often have clothes caught when they enter and exit; in addition, the traditional The lift-type door locks in the market are either simple in structure, using the lock handle to directly lift the lock point, and the internal structure combination is rigid, or the structure is complex, and the components are prone to failure, which greatly reduces the use experience and service life. Contents of the invention [0003] In order to solve the above-mentioned problems and make up for the deficiencies of the traditional technology, the present invention provides a built-in lifting push-pull door lock...
