Description

Technical Field

[0001] This utility model relates to the field of gas detector calibration technology, and in particular to a novel bracket for gas detector calibration. Background Technology

[0002] A gas detector is an instrument for detecting gas concentrations. It is suitable for hazardous locations where flammable or toxic gases are present, and can continuously monitor the concentration of the gas in the air up to its lower explosive limit. It is widely used in various industries such as gas, petrochemicals, metallurgy, steel, coking, and power generation, where flammable or toxic gases are present, making it an ideal monitoring instrument for ensuring property and personal safety.

[0003] Combustible gas circulation mixing chamber is an essential device for the calibration and inspection of gas detectors. In traditional combustible gas mixing chambers, the detector bracket is fixed by manually rotating the shaft 4 and using screws.

[0004] However, there are many types and sizes of gas detectors on the market, making it difficult to find a single mounting bracket that is compatible with all detectors. Furthermore, since traditional mounting brackets use a mechanical manual rotating shaft, the door needs to be reopened and manually rotated for each orientation test, which increases calibration time and safety, and results in gas waste. Utility Model Content

[0005] The purpose of this invention is to solve the problem mentioned in the background art that there are many types and sizes of gas detectors, making it difficult to find a single bracket that is compatible with all detectors. Therefore, this invention proposes a new type of bracket for gas detector calibration.

A motor is fixedly connected to one side of the fixed bracket, and a rotating shaft is fixedly connected to the output end of the motor. A rotating bracket is fixedly connected to the end of the rotating shaft away from the motor. Multiple electromagnets are fixedly connected to the side of the rotating bracket away from the rotating shaft. Multiple fixing blocks are fixedly connected to the side of the detector body close to the rotating bracket. The fixing blocks are provided with fixing holes corresponding to the electromagnets.

[0008] Preferably, the fixed bracket and the motor are provided with a plurality of corresponding fastening holes.

[0009] Preferably, a connecting rod is fixedly inserted at the center of the rotating bracket, and the detector body is provided with a connecting groove corresponding to the connecting rod.

[0010] Preferably, a locking plate is fixedly connected to the bottom of the fixed bracket, and the locking plate is provided with multiple locking holes.

[0011] Preferably, a plurality of support blocks arranged in a ring are fixedly connected to the side of the fixed bracket near the rotating bracket, and ball bearings are rotatably connected inside the support blocks, with the edges of the ball bearings contacting the rotating bracket.

[0012] Preferably, a plurality of the electromagnets are arranged around the outside of the rotating bracket.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In this utility model, by replacing the original screw holes on the fixed plate with controllable electromagnets, the electromagnets attract the device after the control switch is turned on, which effectively solves the problem of incompatibility of screw holes on the bracket caused by different detector sizes.

[0015] 2. This utility model solves the problem of wasted personnel and costs caused by frequent door openings and manual equipment rotation during orientation experiments by replacing the mechanical rotating shaft with stepper motor control. Attached Figure Description
