The invention relates to an installation fixture for testing transmission door and window lever handles. The installation fixture comprises a fixing part, an adjusting part, a base and a centering part; a transmission door / window lever handle is installed on the fixing part through screws; the fixing part is confined in a waist-shaped limiting groove of the adjusting part by screws for adjusting the x-axial position of the lever handle; the other pair of waist-shaped limiting grooves of the adjusting part are respectively sleeved on two bolts of the base for adjusting the y-axial position of the lever handle; the base is fixed on the base surface of the equipment, and is used for supporting the adjusting part, the fixing part and the door and window lever handle for transmission. The centering part is installed on the rotating shaft of the driving arm, and aligns the rotating shaft center of the door and window lever handle for transmission by emitting infrared light beam. Compared with the prior art, the invention can realize the precise clamping when the lever handles of a door and window for transmission are tested, and provides the guarantee for the detection of the handled performance index. At the same time, the invention can be applied to the lever handles of different types and mounting holes, and has wide universality.
Description
technical field [0001] The invention relates to a test installation fixture for a door and window handle for transmission. Background technique [0002] The door and window handle for transmission has been widely used in the construction industry. It is used in conjunction with the transmission locker and multi-point locker in the door and window to realize the locking and unlocking of the door and window lock points. According to the requirements of the relevant test standards for transmission door and window handles, when testing performance indicators such as life, force and torque, the contact point must be calibrated at the position of the specified length of the handle. Before calibrating the contact point of the handle handle, it is necessary to measure the length from the center of rotation of the handle to the outermost end of the handle. In addition, when testing performance such as life, force and moment, if the rotation axis of the driving arm can be coaxial wit...
