Description

Technical Field

[0001] The utility model belongs to the technical field of gas detection alarm equipment, and in particular relates to a portable gas detection alarm instrument. Background Art

[0002] Portable gas detection alarm is a gas leak detection alarm instrument. When flammable or toxic gas leaks in an industrial environment, the detection alarm detects that the gas concentration reaches the critical point set by the explosion or poisoning alarm, and the alarm will send out an alarm signal to remind workers to take safety measures and drive the exhaust, cut-off, and spray systems to prevent explosions, fires, and poisoning accidents, thereby ensuring safe production.

[0003] The existing portable gas detection alarm is generally a handheld instrument, with a detection tube for air intake at the top of the instrument. The detection tube can suck the gas in the environment into the instrument for detection and analysis. However, the detection tube of the existing portable gas detection alarm is usually protruding and exposed at the top of the instrument. It is easy to be bumped during carrying, which shortens the service life of the instrument. Utility Model Content

[0008] As a preferred implementation, a guide rod is fixedly installed in another slide groove, and another connecting block is slidably sleeved on the guide rod.

[0009] As a preferred implementation, a sealing ring is fixedly connected to the inner wall of the lower end of the detection tube.

[0010] As a preferred implementation, a rotating shaft is fixedly connected to the top end of the back side of the gas detector body, and a cover plate is hinged on the rotating shaft.

[0011] As a preferred implementation, a torsion spring is mounted on the rotating shaft, and the cover is automatically closed by the torsion spring.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The portable gas detection alarm device is provided with a receiving slot. When the device is carried, the detection tube is retracted into the receiving slot, which can prevent the receiving slot from being hit and extend the service life of the device. When the device is used for detection, the motor can be started to drive the screw to rotate, so that the screw drives the connecting block to slide along the slide slot, so that the connecting block drives the detection tube to extend from the top of the receiving slot along the air inlet pipe, and the detection tube can be used for detection, which is convenient to use.
