Shear lifting mechanism producing large swing angle motion

Abstract

The invention relates to a shear lifting mechanism producing large swing angle motion. The shear lifting mechanism comprises a fixing plate, a transmission rod, a driving rod, an off-axis driven rod and a shear force rod group, wherein the fixing plate is mounted at a door and window sash end, the transmission rod is arranged on the fixing plate in a sliding manner, one end of the transmission rodis connected with a drive execution mechanism, and the other end and one end of the driving rod are hinged to the fixing plate; the other end of the driving rod is hinged to the middle of the off-axis driven rod; one end of the shear force rod group is hinged to the top end of the fixing plate and one end of the off-axis driven rod; the other end is hinged to the door and window sash end; and theother end of the off-axis driven rod is hinged to the fixing plate. The shear lifting mechanism changes a drive force bearing point and a force output point on the basis of a linear lifting functionof traditional shear lifting, so that short-range linear reciprocation can be realized, large travel pushing and contraction motion can be produced, and sector motion at a large swing angle can be realized.

Description

technical field [0001] The invention relates to the field of door and window components, in particular to a scissors lifting mechanism that generates a large swing angle motion. Background technique [0002] At present, due to the structure and the setting of the force point of the shear lift mechanism of the door and window components, the opening angle is not much different from the pushing angle, which requires a large range to open a large angle, which is not convenient for subsequent doors and windows. Due to the needs of the development of automation, it is still impossible to realize the movement of short stroke and large swing angle. Contents of the invention [0003] In order to solve the above problems, the present invention provides a scissor lift mechanism that produces a large swing angle movement. The present invention changes the drive force point and force output point on the function of the traditional scissor lift to achieve linear lift, so that it can re...
