Description

Technical Field

[0001] The utility model relates to an operating device, in particular to an electric aging operating device for a catalytic combustible gas detector, belonging to the technical field of production and manufacturing of catalytic combustible gas detectors. Background Art

[0002] A combustible gas detector is a detection instrument that responds to the concentration of single or multiple combustible gases, including two types: catalytic type and infrared optical type, where:

[0003] The catalytic combustible gas detector measures the concentration of combustible gas by using the resistance change of a refractory metal platinum wire after heating. That is, when the combustible gas enters the detector, an oxidation reaction is caused on the surface of the platinum wire. The heat generated makes the temperature of the platinum wire rise, causing the resistivity of the platinum wire to change. The concentration of the combustible gas can be measured by detecting the resistivity of the platinum wire;

[0004] The infrared optical combustible gas detector, on the other hand, uses the absorption principle of infrared light sources by alkane combustible gases to detect the concentration of combustible gas in the on-site environment through an infrared sensor.

[0005] Since the catalytic combustible gas detector measures the concentration of combustible gas by using the resistance change of a refractory metal platinum wire after heating, the condition of the oxide layer on the surface of the platinum wire has a very important influence on its detection response and detection accuracy.

[0006] Therefore, before the formal market launch of the catalytic combustible gas detector, it is usually necessary to conduct power-on aging or simply electric aging on it, that is, to apply electricity to the platinum wire inside the catalytic combustible gas detector to pre-form a dense and uniform oxide layer on the surface of the platinum wire, so as to ensure the consistency of the initial working conditions of the catalytic combustible gas detector, thereby ensuring its working stability and detection accuracy.

[0007] In the prior art, the power-on aging operation of the catalytic combustible gas detector is usually carried out independently one by one. Obviously, such an operation method is time-consuming and laborious, with very low work efficiency, affecting the economic benefits of the enterprise. Content of the Utility Model

[0075] The locking claw 51 is a J-shaped member and is arranged at the end of the locking end of the slot cover 40. The locking frame 52 is arranged on the tabletop 10 of the operation table 10 on the side where the locking end is located. The buckle 53 is arranged inside the locking frame 52. One end of the telescopic rod 54 has a plug, and the plug is located outside the locking frame 52. The rest of the telescopic rod 54 penetrates into the side wall of the locking frame 52 and enters the inside of the locking frame 52 and is connected to the buckle 53. The spring 55 is sleeved on the telescopic rod 54 located inside the locking frame 52. The buckle 53 can extend under the action of the spring 55 to lock and fix the locking claw 51 inserted into the locking frame 52, and the buckle 53 can also release and unlock the locked locking claw 51 by pulling back the plug.

[0076] Furthermore, one side or both sides of the buckle 53 are also provided with limiting sliders 56, and the inner side wall of the locking frame 52 corresponding to the limiting sliders 56 is also provided with limiting grooves 57 adapted to the limiting sliders 56. The limiting sliders 56 are embedded in the limiting grooves 57 to limit the distance of the buckle 53 moving back and forth in the locking frame 52.

[0077] Furthermore, as Figures 1 to 3 shown, a support rod 12 is also arranged at the bottom of the operation table 10.

[0078] Optionally, as Figure 3 shown, the support rod 12 can be adjusted up and down, so that the height of the operation table 10 can be adjusted to better adapt to the operation environment and the operation of the operator.
