[0016] In order to make the technical scheme of the application more clear, the application is further described in detail below in combination with the drawings and specific embodiments.

[0017] Embodiment 1

[0018] According to the drawings Figures 1-3The utility model provides a kind of gas detection sensor protection structure, including cover plate 3 and gas detection sensor 4, the front surface of gas detection sensor 4 is embedded with display screen 5, display screen 5 is fixedly connected with gas detection sensor 4, the front surface of gas detection sensor 4 is close to the periphery of display screen 5 is equipped with multiple spiral springs 7, multiple spiral springs 7 are all pasted with gas detection sensor 4, the front surface of multiple spiral springs 7 is provided with a plastic ring 6, plastic ring 6 is fixedly connected with spiral spring 7, the rear surface periphery of plastic ring 6 is equipped with telescopic cylinder 8, telescopic cylinder 8 is pasted with plastic ring 6, telescopic cylinder 8 is pasted to the front surface of gas detection sensor 4 behind, the front surface of plastic ring 6 is provided with circular shaft 1 above, circular shaft 1 is fixedly connected with plastic ring 6, the front surface of circular shaft 1 is equipped with baffle 9, baffle 9 is fixedly connected with circular shaft 1, the outer lateral wall of circular shaft 1 is equipped with cover plate 3, cover plate 3 is rotatably connected with circular shaft 1.

[0019] The front surface of cover plate 3 is provided with a plurality of rubber vertical bars 2, which are fixedly attached to cover plate 3. When the staff wants to rotate the cover plate 3, the fingers can be contacted on the rubber vertical bars 2, and the cover plate 3 can be rotated by pushing it with the fingers. The rubber vertical bars 2 can play a role of anti-skid, which facilitates the staff to push and rotate the cover plate 3, so as to open the cover plate 3.

[0020] In the embodiment, the cover plate 3 is located in front of the plastic ring 6, and the cover plate 3 is rotatably connected with the plastic ring 6. The cover plate 3 can be rotated by 360°. When it is needed to view the data on the display screen 5, the cover plate 3 can be held and rotated, which is simple to operate.

[0021] In the embodiment, the telescopic cylinder 8 is located at the periphery of the plurality of spiral springs 7. The telescopic cylinder 8 is a rubber bellows. The telescopic cylinder 8 can be compressed and shortened. The telescopic cylinder 8 can shield dust from the periphery of the spiral springs 7. Moreover, due to the presence of the telescopic cylinder 8, the spiral springs 7 can not be blocked when compressed.

[0022] In the embodiment, the diameter of the baffle 9 is greater than the diameter of the circular shaft 1. The baffle 9 plays a blocking role, which can prevent the cover plate 3 from falling off the circular shaft 1.
