Two-way lock box structure and door/window using structure

Abstract

The invention provides a two-way lock box structure and a door / window using the structure. The technical key point of the two-way lock box structure is as follows: the two-way lock box structure comprises a bottom plate, two parallel panels mounted on the bottom plate, a rotating handle articulated with the panels, a driving part, a first driving bar linked with the driving part and capable of sliding along the bottom plate and a second driving bar capable of reversely driving with the driving part through a gear-rack component and sliding along the bottom plate, wherein the rotating handle comprises a shifting rod; the driving part is provided with a shifting groove driven to move horizontally by the shifting rod; a notch part capable of reversely stopping is formed in the top end of theshifting groove; the rotating handle also comprises a limiting part used for limiting upward swing of the shifting rod; when the shifting rod enters the notch part of the shifting groove, the shiftingrod is in an upward swing position; if the driving bars are reversely pushed, the shifting rod is continuously jacked upwards by the notch part; in addition, the limiting part is used for limiting the upward swing of the shifting rod, and the shifting rod is locked and cannot be pushed, so that the lock box structure has a function of preventing prying; the driving part can be punched and moldedby stainless steel; compared with the existing zinc alloy die-casting parts, the strength of the driving part is higher.

Description

technical field [0001] The invention relates to the technical field of doors, windows and hardware accessories thereof, in particular to a two-way lock box structure for doors and windows and a door / window using the structure. Background technique [0002] In the existing two-way lock box structure, there are usually two structures to realize two-way transmission, one is a multi-link transmission structure, and the other is a rack and pinion transmission structure; in the multi-link transmission structure, multiple connecting rods pass through The hinge shaft is hinged to achieve linkage, and multiple pins need to be set to limit the movement trajectory of the connecting rod. Therefore, there are many parts, and the force between the stacked connecting rods is uneven, resulting in an unstable internal structure. And in the rack and pinion transmission structure, generally comprise driving gear and driven gear, as the Chinese real new patent that authorized announcement numbe...

Problems solved by technology

[0002] In the existing two-way lock box structure, there are usually two structures to realize two-way transmission, one is a multi-link transmission structure, and the other is a rack and pinion transmission structure; in the multi-link transmission structure, multiple connecting rods pass through The hinge shaft is hinged to achieve linkage, and multiple pins need to be set to limit the movement trajectory of the connecting rod. Therefore, there are many parts, and the force between the stacked connecting rods is uneven, resulting in an unstable internal structure.

And in the rack and pinion transmission structure, generally comprise driving gear and driven gear, as the Chinese real new patent that authorized announcement number is CN205976751U, disclose a kind of novel two-way transmission lock box, its principle is to drive the large gear by handle, with The meshing pinion drives the rack A and rack B for two-way transmission, but the structure of the lock box has the following disadvantages: On the one hand, in order to ensure the stability of the transmission (not only to ensure the width of the meshing surface of the rack and pinion, but also to prevent sideways swing in the rack transmission), the rack needs to reach a certain width, resulting in the rack parts usually can only be molded by zinc alloy die-casting, the strength of the parts is not high, and easy to corrode; on the other hand, the lock box lacks Anti-theft structure, when the rack A or rack B is pushed in the opposite direction, the lock box can be opened from the outside without using the handle
