Bidirectional transmission lock box for flat-opened doors and windows

Abstract

The invention relates to the technical field of building hardware, and particularly discloses a bidirectional transmission lock box for flat-opened doors and windows. The bidirectional transmission lock box for the flat-opened doors and the windows comprises a first wheel guard plate and a second wheel guard plate, and is characterized in that center holes, threaded column mounting holes, semicircle grooves, ratchet wheel grooves and small windows are formed in the first wheel guard plate and the second wheel guard plate correspondingly, a small mounting hole corresponding to the center hole is formed in the second wheel guard plate, driving gears are mounted in the center holes, a small gear is arranged in the small mounting hole, and clamping columns are arranged in the semicircle grooves; and the driving gears mesh with a first rack and the small gear, and the small gear meshes with a second rack. According to the bidirectional transmission lock box for the flat-opened doors and thewindows, the structure is reasonable, safety and reliability are achieved, the mechanical performance is stable, the transmission accuracy is high, the defects of unattractive mounting, poor transmission performance, poor use experience of the whole windows and the like in the prior art are overcome, the advantage of quick mounting is achieved, and the user experience of the doors and windows isimproved more advantageously.

Description

(1) Technical field [0001] The invention relates to the technical field of architectural hardware, in particular to a two-way transmission lock box for casement doors and windows. (2) Background technology [0002] At present, there are many kinds of transmission lock boxes for cooking, and two-way transmission lock boxes have become more and more common. However, the existing products in the market all use screws for end-face installation, which destroys the profile and poor installation aesthetics; the transmission structure is the movement of the active rack with the driven rack, which has poor mechanical effects and affects product performance; the handle installation screw directly passes through the transmission lock. box, the lock box will tilt during the tightening process, and the transmission experience of the whole window is poor. Therefore, improving the overall performance of the two-way transmission lock box is an important issue that the construction hardware...
