[0002] A carbon monoxide detector is a gas detection instrument with a high-brightness liquid crystal display that can be flexibly configured with a variety of different gas sensors.

[0003] In the prior art patent (Patent Name: A Carbon Monoxide Concentration Tester; Application Number: 202320984741.2), by providing a rotating cylinder, a rotating disc, a detection head, a movable disc and a slider, by flipping the rotating disc outwards and simultaneously rotating the retracting cylinder movably connected inside the rotating groove, the detection head fixedly connected to the bottom end with a movable disc is retracted and protected.

[0004] The above-mentioned technical patent has the following defects: (1) Before retracting the detection head, it is necessary to open and close the rotating disc, resulting in inconvenient use of the detection head; (2) The protection structure function of the detection head is relatively single, only having a protection function and unable to realize the installation function of the tester, so that the installation method of the tester is limited, reducing the convenience during use. Therefore, a carbon monoxide concentration tester is proposed to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems in the prior art, and a carbon monoxide concentration tester is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A carbon monoxide concentration tester includes a tester body. A detection head for detecting the carbon monoxide concentration is arranged at the top end of the tester body. A slide rail distributed circumferentially around the detection head is fixedly connected to the top end of the tester body. A slider is slidably connected to the inner side of the slide rail. A protection plate is fixedly connected to the top end of the slider. An arc-shaped support plate is fixedly connected between adjacent slide rails at the top end of the tester body, and multiple arc-shaped support plates form a cylindrical shape.

[0008] Preferably, the protection plate is composed of an arc-shaped plate and a sector-shaped plate, and the sector-shaped plate is fixedly connected to the top end of the arc-shaped plate.

[0009] Preferably, opposite reset springs are fixedly connected to the back of the protection plate, and one end of each reset spring is fixedly connected to the inner wall of the arc-shaped support plate.

[0010] Preferably, a trapezoidal block is fixedly connected to the back of the protection plate, and one end of the inclined surface of the trapezoidal block passes through the gap between adjacent arc-shaped support plates.

[0011] Preferably, external threads are commonly provided on the outer surfaces of multiple arc-shaped support plates, and an internally threaded ring is threadedly connected to the outer surfaces of the multiple arc-shaped support plates. The bottom end face of the internally threaded ring is inclined.

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

[0013] By providing a protection plate, arc-shaped support plates, an internally threaded ring, and trapezoidal blocks, the present utility model rotates the internally threaded ring clockwise to move it downward and press the inclined surface of the trapezoidal block, so that the trapezoidal block drives the protection plate to move towards the detection head and form a cylindrical structure, realizing the function of wrapping and protecting the detection head and avoiding the detection head from being collided;

[0014] When using the detection head, rotate the internally threaded ring counterclockwise to move it upward. Under the pulling force of the return spring, the protection plates move away from each other. Then rotate the internally threaded ring clockwise again, so that each protection plate realizes the clamping function for an object (such as a bump or a hanging rope), and the installation function of the tester can be realized.

[0021] 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 the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0022] Referring to Figures 1-5 , a carbon monoxide concentration tester includes a tester body 1. A detection head 8 for detecting the carbon monoxide concentration is provided at the top of the tester body 1. A slide rail 7 distributed circumferentially around the detection head 8 is fixedly connected to the top of the tester body 1. A slider 9 is slidably connected to the inner side of the slide rail 7. A protection plate 2 is fixedly connected to the top of the slider 9. The setting of the slide rail 7 facilitates the movement of the protection plate 2. An arc-shaped support plate 3 is fixedly connected between adjacent slide rails 7 at the top of the tester body 1, and a plurality of arc-shaped support plates 3 form a cylindrical shape.

[0023] The protection plate 2 is composed of an arc-shaped plate and a sector-shaped plate. The sector-shaped plate is fixedly connected to the top of the arc-shaped plate. When the protection plate 2 is closed, a closed space is formed around the protection plate 2, and a circular opening structure is formed at the top.

[0024] Oppositely arranged return springs 6 are fixedly connected to the back of the protection plate 2. One end of each return spring 6 is fixedly connected to the inner wall of the arc-shaped support plate 3. The setting of the return springs 6 enables, after the internal thread ring 4 moves upward, the trapezoidal block 5 to lose the extrusion force of the internal thread ring 4, and under the pulling force of the return springs 6, the protection plate 2 is reset.

[0025] A trapezoidal block 5 is fixedly connected to the back of the protection plate 2. One end of the inclined surface of the trapezoidal block 5 passes through the gap between adjacent arc-shaped support plates 3. External threads are commonly provided on the outer surfaces of a plurality of arc-shaped support plates 3, and an internal thread ring 4 is commonly threadedly connected to the outer surfaces of a plurality of arc-shaped support plates 3. The bottom end face of the internal thread ring 4 is inclined.

[0026] It should be noted that when the internal thread ring 4 moves downward, the internal thread ring 4 will push the inclined surface of the trapezoidal block 5, causing the trapezoidal block 5 to drive the protection plate 2 to move towards the detection head 8, and the protection plate 2 is closed to achieve the function of wrapping and protecting the detection head 8, avoiding the collision of the detection head 8.

[0027] When the utility model is in use, when it is necessary to use the detection head 8, the internal thread ring 4 can be rotated counterclockwise, so that the internal thread ring 4 moves upward. After the internal thread ring 4 moves upward, the trapezoidal block 5 loses the extrusion force of the internal thread ring 4. Under the action of the pulling force of the return spring 6, the protection plate 2 is reset (the protection plate 2 moves away from the detection head 8), so that the detection head 8 is exposed, facilitating the detection of carbon monoxide concentration. By rotating the internal thread ring 4 clockwise, the protection plates 2 everywhere can realize the clamping function of an object (such as a bump or a hanging rope), and the installation function of the tester can be realized;

[0028] When the detection head 8 is not in use, by rotating the internal thread ring 4 clockwise, the internal thread ring 4 will push the inclined surface of the trapezoidal block 5, so that the trapezoidal block 5 drives the protection plate 2 to move towards the detection head 8, and the protection plate 2 closes to realize the wrapping protection function of the detection head 8, avoiding the collision of the detection head 8.

[0029] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the utility model.
