Description

Technical Field

[0001] This utility model relates to the field of gas detector technology, and specifically to a gas detector with an extended probe. Background Technology

[0002] A gas detector is an instrument for detecting gas concentrations. This instrument is suitable for hazardous locations where flammable or toxic gases are present. It can continuously monitor the concentration of the gas in the air up to its lower explosive limit for extended periods. It is widely used in various industries such as gas, petrochemicals, metallurgy, steel, coking, and power generation where flammable or toxic gases are present. It is an ideal monitoring instrument for ensuring the safety of property and personnel. Gas detectors can detect: flammable gases: natural gas (methane), liquefied petroleum gas (isobutane, propane), coal gas (hydrogen), acetylene, pentane, alkynes, alkenes, alcohol, acetone, toluene, alcohols, hydrocarbons, light oil, and various liquid vapors; toxic gases: carbon monoxide, hydrogen sulfide, ammonia, chlorine, oxygen, phosphine, sulfur dioxide, hydrogen chloride, chlorine dioxide, and many other toxic and harmful gases.

[0003] Gas detectors have a wide range of applications. However, the probes of some existing gas detectors cannot be adjusted. When gas needs to be detected in a narrow space, the probe is often too far from the gas to be detected, which affects the accuracy of gas detection. Therefore, there is an urgent need for a gas detector with an extended probe to overcome the above defects. Utility Model Content

[0004] The purpose of this invention is to provide a gas detector with an extended probe head, which has the advantage of easy adjustment, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gas detector with an extended probe, comprising a gas detector body, a moving assembly, a probe assembly, and a gas guide spring tube. The moving assembly is located on the left side of the gas detector body, and the gas guide spring tube is connected to the left side of the top of the gas detector body. The probe assembly is located on the top of the moving assembly. The moving assembly includes an L-shaped moving rod, a first sliding groove, a first threaded rod, a first slider, an L-shaped connecting seat, and a drive motor. The probe assembly includes a moving probe, a positioning ring, a positioning rod, a fixed seat, a metal hose, a gas guide tube, a second sliding groove, a second slider, a U-shaped frame, a second threaded rod, a fixed block, a turntable, a connecting rod, and a sealing ring.

[0006] Furthermore, the L-shaped moving rod is fixedly installed at the bottom left side of the gas detector body, the drive motor is fixedly installed at the bottom of the L-shaped moving rod, the first slide groove is opened inside the L-shaped moving rod, and the first slider slides inside the first slide groove.

[0007] Furthermore, the first threaded rod rotates inside the first slider via a thread, the L-shaped connecting seat is fixedly installed on the right side of the first slider, and the output shaft of the drive motor passes through the inner cavity of the first slide groove and is fixedly connected to the bottom of the first threaded rod.

[0008] Furthermore, the metal hose is positioned on top of the L-shaped connector, the fixing seat is connected to the top of the metal hose, the positioning rods are fixedly installed on both sides of the top of the fixing seat, and the air guide tube is connected to the center of the top of the fixing seat.

[0009] Furthermore, the second groove is formed inside the positioning rod, the second slider slides inside the second groove, a U-shaped frame is fixedly installed on the back of the second slider, and the movable probe head is set on the surface of the air duct.

[0010] Furthermore, the positioning ring is fixedly installed on the surface of the moving probe, the sealing ring is fixedly installed in the inner cavity of the moving probe, the connecting rod is fixedly installed on the top of the second slider, and the top of the connecting rod is fixedly connected to the bottom of the positioning ring.

[0012] Furthermore, the surface of the second threaded rod is rotatably connected to the inside of the fixed block via a bearing, and the top of the air guide spring tube extends through to the top of the L-shaped connector and communicates with the bottom of the metal hose.

[0013] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:

[0014] This invention detects gas through the cooperation of the gas detector body, the gas-conducting spring tube, and the detector head assembly. A movable component allows for height adjustment of the detector head assembly. During use, adjusting the height involves activating the drive motor, which rotates the first threaded rod, causing the first slider to move the L-shaped connecting seat upwards. Simultaneously, the gas-conducting spring tube deforms and moves upwards synchronously with the detector head assembly. Adjusting the position of the movable detector head allows for further adjustment. Rotating the turntable rotates the second threaded rod, which in turn moves the U-shaped frame, the second slider, the connecting rod, and the positioning ring upwards, thus adjusting the position of the movable detector head. This design offers convenient adjustment and solves the problem of some existing gas detectors where the detector head cannot be adjusted, resulting in the detector head being too far from the gas detection location in confined spaces, affecting detection accuracy.
