Technical Field

[0002] A floor spring is a hydraulic door closer, and the device for pressing the spring is a turbine instead of a rack and pinion. The detection method of "zero position deviation" in the new version of "GB / T2697-2013" standard is described as follows: Connect the indicating rod to the output shaft of the floor spring with screws, and use a dynamometer to push the indicating rod to rotate. When the reading of the dynamometer is 16N - 17N, record the offset distance at 300mm of the indicating rod.

[0003] After retrieval, in the application with the patent application number 201720778560.9, a detection device for door control hardware floor spring is disclosed, and in particular, a detection device for detecting the zero position deviation of the floor spring is disclosed. The detection device for detecting the zero position deviation of the floor spring includes a floor spring fixing device arranged on the bottom plate, and is characterized in that: a floor spring is fixed on the floor spring fixing device, one end of the output shaft of the floor spring is connected to one end of the indicating rod, and a measurement deviation device is correspondingly arranged at the other end of the indicating rod, and a scale is extended on the measurement deviation device corresponding to the indicating head on the indicating rod;

[0004] Although the detection device for the door control hardware floor spring controls the pulling force by the rotation of the screw and can accurately ensure that the force value is between 16 - 17N, the detection device for the door control hardware floor spring measures the displacement at 300mm of the indicating rod through a scale, which is likely to cause a large detection error.
