Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a gas sensor with a movable protective cover. Background Technique

[0002] A gas sensor is a device that converts information such as the composition and concentration of a gas into information that can be utilized by personnel, instruments, computers, etc., and is a converter that converts the volume fraction of a certain gas into a corresponding electrical signal. When the existing gas sensor is in use, it will be placed in a protective cover to protect the gas sensor, which can avoid damage caused by collision and can also avoid contamination and corrosion by dust and water vapor in the air.

[0003] The protective covers for existing gas sensors are all of fixed sizes and do not have the function of moving and stretching, so the protection area cannot be adjusted. In different use environments, different protection areas are required, which will bring inconvenience to the use of gas sensors. Therefore, we provide a gas sensor with a movable protective cover.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1-4 shown, the present utility model provides a technical solution: a gas sensor with a movable protective cover, including a protective cover 1. The protective cover 1 includes a fixed cover 11 with openings on both the left and right sides. On both the left and right sides of the fixed cover 11, there are movable covers 12 with openings on the sides close to the fixed cover 11. The fixed cover 11 and the two movable covers 12 form the protective cover 1.

[0024] Specifically, a fixed sleeve 2 is arranged in the inner cavity of the fixed cover 11. A gas sensor 4 is connected through the inner cavity of the fixed sleeve 2. The fixed sleeve 2 and the gas sensor 4 are fixedly connected by screws. During installation, the gas sensor 4 can be placed in the fixed sleeve 2 and then fixed by screws.

[0025] Among them, the outer ring of the fixed sleeve 2 is fixedly connected to the inner ring of the fixed cover 11 through a plurality of support rods 3. The fixed sleeve 2 is fixed to the inner wall of the fixed cover 11 through a plurality of support rods 3.

[0026] Furthermore, a filling groove 21 is opened between the inner and outer walls of the fixed sleeve 2. The inner cavity of the filling groove 21 is filled with a soft pad 22. The soft pad 22 can be made of soft materials such as cotton and sponge. The soft pad 22 can buffer and protect the gas sensor 4, making it not easily damaged when subjected to external collisions.

[0027] Specifically, a through hole 122 is opened on the side of the movable cover 12 away from the fixed cover 11. A plurality of sealing pieces 5 are evenly arranged in the inner cavity of the through hole 122. The sealing pieces 5 can be made of materials such as rubber and silica gel. The wires and air pipes connecting the gas sensor 4 to external devices can be led out through the through hole 122. The sealing pieces 5 can seal the through hole 122 to prevent dust and water vapor in the air from entering the protective cover 1, and can protect the gas sensor 4 from being contaminated and corroded.

[0028] Specifically, insertion covers 111 are arranged on both the left and right sides of the fixed cover 11, with openings on both the left and right sides. On the side of the movable cover 12 close to the fixed cover 11, insertion slots 121 are opened. The insertion covers 111 are inserted into the inner cavities of the insertion slots 121. During use, by pulling out or inserting the insertion covers 111 into the insertion slots 121, the overall length of the protective cover 1 can be adjusted, so that it has a movable telescopic function, and further the protection area can be adjusted, providing convenience for the use of the gas sensor.

[0029] Furthermore, a plurality of threaded grooves 112 are evenly formed in the outer circumference of the insertion cover 111, and a plurality of insertion holes 123 are evenly formed in the outer circumference of the movable cover 12. The insertion holes 123 and the corresponding threaded grooves 112 are fixedly connected by bolts. Before adjusting the length of the protective cover 1, the bolts can be loosened and withdrawn from the insertion holes 123 and the threaded grooves 112. After adjustment, they are inserted into the insertion holes 123 and the corresponding threaded grooves 112 again to fix the insertion cover 111 in the insertion slot 121, thereby fixing the fixed cover 11 and the movable cover 12 together.
