Window handle multi-functional detection machine

Abstract

The invention discloses a window handle multifunctional detection machine, which includes a workbench, and is characterized in that it also includes a usability test device and a strength performance test device; the usability test device includes a simulated window; a swing cylinder is fixedly connected to the mounting plate , the swing cylinder is connected to the "7"-shaped transmission rod, and the "7"-shaped transmission rod is directly below the simulation window and the movable sleeve assembly is set on the cross bar; one side of the mounting frame is provided with a cantilever beam, and the other end of the cantilever beam is connected with a nylon wedge seat The strength performance testing device includes a bearing platform, a loading plate, a loading head, a transmission shaft and a handle frame; the handle frame is arranged under the bearing platform; the strength performance testing device also includes a weight for loading the load plate. Realize the operation torque test, wind pressure test, closed gap test, service life test and additional operating force test of the test handle on the same workbench, and truly simulate the use of the handle without increasing the need for test execution. Hand wear.

Description

technical field [0001] The invention belongs to the technical field of window handle detection, and relates to detection equipment for window handle operating torque, wind pressure resistance, closing gap, service life and ability to resist additional external force, specifically a multifunctional detection machine for window handles. Background technique [0002] When people use the handle to close the window sash and turn the dead bolt to compress the wedge-shaped seat to lock the window sash, the handle is subjected to tension on the handle, and the dead bolt rotates while overcoming the elastic resistance of the sealing strip and pressing the wedge-shaped seat. Therefore, to analyze and judge the quality of the handle, in addition to the most basic appearance inspection and feel, the most important thing is to judge the performance of the handle. For this reason, it is necessary to simulate the actual use of the handle to test the operating torque, Additional torque test...

AI Technical Summary

Problems solved by technology

[0004] 1. The life test is carried out under the condition that the deadbolt simulates the elastic resistance, but the handle fails to simulate the tensile force, which cannot really simulate the actual use of the handle;

[0005] 2. Its reciprocating force cannot be 100% converted into the rotational force of the handle, and the rotation of the handle is not very smooth. Not only the rotation angle is small, but the actual rotatable angle of the handle cannot be completely simulated, but also the wear of the handle will be increased.
