Universal electric furnace switch having counting function

Abstract

The invention discloses a universal electric furnace switch having a counting function. The universal electric furnace switch comprises a knob switch, a pin shaft and a counter. A zigzag groove changing with a rotating angle of a rotary shaft is formed in the rotary shaft of the knob switch along the cross section of the rotary shaft, the grooving direction of the zigzag groove is in the circumference direction of the rotary shaft, the groove bottom face of the zigzag groove is connected with the outer circumferential face of the rotary shaft in the rotating direction of the rotary shaft, and the depth of the zigzag groove is changed in the radial direction of the rotary shaft. The width of the zigzag groove is consistent to the diameter of the pin shaft. When an operator turns the knob switch, the rotary shaft of the knob switch gradually pushes the pin shaft to gradually exit out of the zigzag groove, the pin shaft performs linear motion along a via hole with rotation of the rotary shaft and triggers a counting switch on the counter, the counting switch records operation information and operation time of current switching and next switching, and the information is displayed to the outside through a display screen. The universal electric furnace switch can automatically record switching times and switching time after opening each time, and informationized management of electric furnace operation is achieved.

Description

technical field [0001] The invention relates to a switch for a universal electric furnace, in particular to a switch for a universal electric furnace with a counting function, which belongs to the technical field of machinery and electronics. Background technique [0002] At present, large-scale construction quality inspection companies need to use various types of test instruments to sample, analyze and inspect buildings when performing inspection tests on buildings, such as using a universal electric furnace to heat and sample samples for analysis. [0003] The operator needs to fill in the operation record after each test operation, which includes the opening time of the instrument and the number of times of use. Due to the level and sense of responsibility of the operator, there are often cases of forgetting or omissions, which makes the test There are hidden dangers in data and equipment management, which is not conducive to the realization of scientific test equipment ...
