Description

Technical Field

[0001] The utility model application relates to the technical field of combustible gas detectors, in particular to a combustible gas detector which is convenient to fix. Background Art

[0002] A combustible gas detector is a detector that responds to the concentration of a single or multiple combustible gases. There are two types: catalytic and infrared optical. It is a point-type gas detection device installed in explosive hazardous environments. It can convert the combustible gas concentration on site into an electrical signal and transmit it to the monitoring equipment in the safe area to achieve the purpose of monitoring the combustible gas concentration on site. It has a wide range of applications.

[0003] When most combustible gas detectors are used, they need to be fixed to the site to be detected by means of mounting parts. However, since the fixing needs to be adjusted according to the site, the combustible gas detectors need to be adjusted according to the shape of the mounting body during installation. For flat mounting bodies, they can be fixed directly by means of fixing plates. When detecting combustible gas transmission pipelines, they need to be fixed to the pipelines, which requires mounting parts that can be used to fix the pipelines. This makes the installation and fixing of combustible gas detectors inconvenient. Summary of the invention

[0008] Furthermore, a shock-absorbing rubber pad is symmetrically fixed to one side of the detector body away from the fixed connecting piece, and the two shock-absorbing rubber pads are both arranged in an arc shape that matches the dial of the detector body.

[0009] Furthermore, a "convex" rotating hole cooperating with the rotating block and the connecting screw is provided inside the fixing sleeve, and the thickness between the fixing sleeve and the fixing connecting piece is greater than the thickness of the supporting block.

[0010] Furthermore, both ends of the fixed contact and one end of the two movable contacts close to the fixed contact are both configured as semicircular shapes, and each movable contact close to the fixed contact has grooves on the upper and lower sides thereof for cooperating with the support block.

[0011] Furthermore, the two support blocks are both arranged in an "I" shape, and one end of the two movable connecting pieces close to the fixed connecting piece is provided with a rotating hole that matches with the middle part of the support block.
