Description

Technical Field

[0001] This utility model relates to the field of physics, and more particularly to industrial gas detectors, especially a gas detection sensor device that is easy to install. Background Technology

[0002] Gas detection sensors are widely used to detect gas leak concentrations, ensuring environmental safety and preventing potential hazards. In existing technologies, gas detection sensors are installed in equipment or embedded in walls, requiring periodic removal for inspection and replacement. However, due to the small size of gas detection sensors and limited installation space, operators must wear protective clothing and gloves, making operation inconvenient and difficult. Special tools are required for removal, making the process cumbersome. Utility Model Content

[0003] The purpose of this invention is to provide a gas detection sensor device that is easy to install, thereby solving the technical problem that it is very difficult to remove and install gas detection sensors in the prior art.

[0004] This utility model provides a gas detection sensor device that is easy to install, including a housing, in which a gas detection sensor is disposed. A boss is provided on the front side of the housing, and through holes are respectively provided on the left and right sides of the boss. The two through holes are coaxially arranged. A pull ring is provided on the front side of the housing. The pull ring includes a pull rod, and one end of a connecting rod is perpendicularly connected to each end of the pull rod. The two connecting rods are arranged in parallel. The other end of the two connecting rods is perpendicularly connected to a short rod. The two short rods are coaxial and facing each other. The two short rods are respectively inserted into the two through holes. The pull ring can rotate around the axis of the through holes. Limit blocks are provided on the left and right sides of the boss on the front side of the housing. The limit blocks are located behind the connecting rods and extend in the vertical direction. A forward-extending protrusion is provided on the upper part of the limit block, and the protrusion is located above the connecting rod.

[0005] Furthermore, the boss has an inner cavity, which is connected to the inner cavity of the shell.

[0006] Compared with existing technologies, this invention offers significant and positive advantages. When the pull ring rotates downwards, it is in a retracted state, occupying no extra space. The limiting block restricts the connecting rod, limiting the downward rotation angle of the pull ring. This ensures that a gap remains between the pull ring and the front side of the housing after downward rotation, allowing the operator to easily rotate the lever upwards to the open state. When the pull ring rotates upwards, it is in the open state. The protrusion further limits the upward rotation angle of the lever, approximately 90°. This allows the operator to easily remove the device by hand or insert it into the corresponding installation area, eliminating the need for special tools, reducing operational difficulties caused by limited space, and improving maintenance efficiency.

[0012] The present invention will be further described below with reference to embodiments, but the present invention is not limited to these embodiments. Any similar variations using the present invention should be included within the protection scope of the present invention. The use of directions such as up, down, front, back, left, right, center, inside, and outside in the present invention is only for the convenience of clear description and is not intended to limit the technical solution of the present invention.

[0013] like Figures 1-5 As shown, this utility model provides a gas detection sensor device that is easy to install, including a housing 1, in which a gas detection sensor is disposed. A boss 2 is provided on the front side of the housing 1, and through holes 3 are respectively provided on the left and right sides of the boss 2. The two through holes 3 are coaxially arranged. A pull ring 4 is provided on the front side of the housing 1. The pull ring 4 includes a pull rod 5. The two ends of the pull rod 5 are respectively vertically connected to one end of a connecting rod 6. The two connecting rods 6 are arranged in parallel. The other ends of the two connecting rods 6 are respectively vertically connected to short rods 7. The two short rods 7 are coaxial and facing each other. The two short rods 7 are respectively inserted into the two through holes 3. The pull ring 4 can rotate around the axis of the through hole 3. Limiting blocks 8 are respectively provided on the left and right sides of the boss 2 on the front side of the housing 1. The limiting blocks 8 are located behind the connecting rods 6 and extend in the vertical direction. A forward-extending protrusion 9 is provided on the upper part of the limiting block 8. The protrusion 9 is located above the connecting rods 6.

[0014] Furthermore, the boss 2 is provided with an inner cavity, and the inner cavity of the boss 2 is connected to the inner cavity of the shell 1.

[0015] The working principle of this utility model: like Figure 1 As shown, when the pull ring 4 rotates downwards, it is in a retracted state, not occupying extra space. The limiting block 8 limits the connecting rod 6, thereby restricting the downward rotation angle of the pull ring 4, ensuring that there is still a gap between the pull ring 4 and the front side of the housing 1 after it rotates downwards. This gap allows the operator to use the operator to rotate the pull rod 5 upwards to the open state. Figure 2 As shown, the pull ring 4 is in the open state after being rotated upwards. The protrusion 9 acts as a limiter on the connecting rod 6, thereby limiting the upward rotation angle of the pull rod 5. The limit angle of the pull ring 4 rotating upwards is about 90°, which makes it easy for the operator to hold the pull rod 5 to take out the device or put it into the corresponding installation area without the need for special tools, reducing the operational difficulties caused by the small space and improving maintenance efficiency.
