It identifies the types of gases present in the environment through built-in sensors, and automatically issues an alarm when the gas concentration exceeds the set safety value to remind the operator.

[0003] The existing high-altitude carbon dioxide detectors in the factory area are mainly installed and positioned by using lugs on the outer wall of the device and bolts. This makes the disassembly and assembly process cumbersome during subsequent maintenance, requiring tools and hindering the quick disassembly and assembly of the device, thus reducing the convenience of subsequent maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide an atmospheric carbon dioxide upper-altitude detector to solve the problem mentioned in the background art, which is that the mounting and positioning of the outer wall of the instrument is done by bolts, which makes it inconvenient to quickly disassemble and assemble the instrument during subsequent maintenance, thus reducing the convenience of subsequent maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an atmospheric carbon dioxide upper-altitude detector, comprising:

[0006] The detection body has a positioning support lug integrally provided on its outer wall;

[0007] The positioning component includes a positioning frame, a support shaft fixedly connected to the top of the positioning frame, and an abutment rotatably connected to the outside of the support shaft. The abutment abuts against the top of the detection body. A support member is fixedly connected to the bottom of the positioning frame, and a positioning lug is inserted into the inside of the support member.

[0008] Preferably, the positioning frame has an isosceles trapezoidal structure, and positioning holes are provided at all four corners of the positioning frame. The bottom outer wall of the positioning frame is integrally formed with a positioning plate.

[0009] Preferably, the support member is fixedly connected to the corner of the positioning frame and the positioning plate, and the support member has an L-shaped structure.

[0010] Preferably, the end of the support shaft away from the positioning frame is provided with a threaded post, and the external thread of the threaded post is connected to a nut, and the nut abuts against the outer wall of the abutment.

[0011] Preferably, the abutment member has a stepped cam structure and is steppedly engaged at the top and rear edge of the detection body.

[0012] Preferably, it also includes an extrusion plate, the height of which is greater than the height of the support member, and one end of a telescopic tube is connected to the side of the extrusion plate that is close to the positioning frame.

[0013] Preferably, a spring is sleeved on the outside of the telescopic tube, and the two ends of the spring abut against the positioning frame and the extrusion plate on the side where they are close to each other. The outer wall of the extrusion plate slides against the outer wall of the positioning plate and the support.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the utility model realizes the quick installation and positioning of the testing machine body through the setting of the snap-fit ​​elastic abutment structure, thereby improving the convenience of its subsequent disassembly and maintenance.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5One embodiment of this utility model is an atmospheric carbon dioxide upper-altitude detector, comprising:

[0023] The testing machine body 1 has a positioning lug 11 integrally formed on its outer wall; the positioning assembly 2 includes a positioning frame 21, a support shaft 22 fixedly connected to the top of the positioning frame 21, and an abutment 23 rotatably connected to the outside of the support shaft 22, the abutment 23 abutting against the top of the testing machine body 1, and a support member 25 fixedly connected to the bottom of the positioning frame 21, with the positioning lug 11 inserted into the inside of the support member 25. The positioning lug 11 and the support member 25 are engaged and positioned to achieve quick installation and positioning of the testing machine body 1. At the same time, the abutment 23 at the top of the testing machine body 1 is used to limit the abutment and ensure the stability of the positioning lug 11 engaged inside the support member 25, preventing it from shaking, thereby ensuring the stability of the installation of the testing machine body 1.

[0024] Furthermore, the positioning frame 21 has an isosceles trapezoidal structure, and positioning holes are provided at all four corners of the positioning frame 21. The bottom outer wall of the positioning frame 21 is integrally formed with a positioning plate 24. The support member 25 is fixedly connected to the corner of the positioning frame 21 and the positioning plate 24. The support member 25 has an L-shaped structure, and the inner wall of the vertical end of the support member 25 is provided with a positioning groove that fits the positioning lug 11. This allows the positioning lug 11 to be precisely engaged in the positioning groove during the installation of the testing machine body 1. Then, the abutment of the top abutment member 23 of the testing machine body 1 is used to achieve auxiliary positioning of the testing machine body 1, ensuring the stability of the installation of the testing machine body 1 and effectively preventing it from shaking randomly.

[0025] Furthermore, a threaded post is provided at the end of the support shaft 22 away from the positioning frame 21, and a nut is connected to the external thread of the threaded post. The nut abuts against the outer wall of the abutment 23, which facilitates the disassembly and maintenance of the abutment 23. The abutment 23 has a stepped cam structure and is steppedly engaged at the top and rear edge of the testing machine body 1. Through the stepped structure of the abutment 23, the top of the testing machine body 1 can be abutted and limited after the positioning support 11 is engaged, thereby preventing the testing machine body 1 from being displaced due to shaking. Through the engagement of the positioning support 11 and the positioning groove and the abutment limitation of the abutment 23, the stability of the installation of the testing machine body 1 is effectively improved.

[0026] Furthermore, it also includes a pressing plate 27, the height of which is greater than the height of the support member 25. One end of a telescopic tube 26 is connected to the side of the pressing plate 27 that is close to the positioning frame 21. A spring 28 is sleeved on the outside of the telescopic tube 26, and both ends of the spring 28 abut against the side of the positioning frame 21 and the pressing plate 27 that are close to each other. The outer wall of the pressing plate 27 slides against the outer walls of the positioning plate 24 and the support member 25. Due to the elastic setting of the spring 28, when the testing machine body 1 is installed, the positioning lug 11 abuts against the pressing plate 27, causing the pressing plate 27 to move backward, thus placing the positioning lug 11 inside the support member 25. This further releases the abutment against the pressing plate 27. The pressing plate 27 is pushed forward by the elastic influence of the spring 28, thereby engaging the positioning lug 11 into the positioning groove of the support member 25. At this time, rotating the abutment member 23 completes the engagement and positioning of the top of the testing machine body 1, thus achieving stable installation of the testing machine body 1.

[0027] Working Principle: The detection body 1 used in this application are all products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here. When using this utility model, firstly rotate the abutment 23 so that the stepped engaging end of the abutment 23 is at the top, and then install the detection body 1. Push the positioning ear 11 to push the extrusion plate 27 backward and then lower it. Then the positioning ear 11 is placed inside the support 25. At this time, the extrusion plate 27 is elastically squeezed and moves forward, so that the positioning ear 11 abuts against the inside of the vertical end positioning groove of the support 25. At the same time, rotate the abutment 23 so that the stepped end of the abutment 23 engages with the top and rear of the detection body 1, which can realize the stable installation and positioning of the detection body 1 and effectively prevent it from shaking. Finally, after the detection body 1 is powered on, it can detect and alarm the concentration of carbon dioxide through its internal sensor.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
