Embodiment
[0021] Such as Figures 1 - 4As shown in the figure, an exhaust gas detection device for a sealed space includes a mounting base 1 and a mounting mechanism. The mounting mechanism includes a detection device 2, which is provided on the top end face of the mounting base 1. A connection slot 11 is opened on the top surface of the mounting base 1. A connection plug 3 is provided on the bottom end face of the detection device 2. The connection plug 3 is movably connected to the inside of the connection slot 11. An activity slot 12 is opened inside the connection slot 11. A connection rotating rod 13 is connected by a bearing inside the activity slot 12. A gear 14 is provided on the outside of the connection rotating rod 13. A connection sliding rod 17 is fixedly connected to the inside of the activity slot 12. The other end of the connection sliding rod 17 is slidably connected to the inside of a positioning plug 15. A spring 18 is sleeved on the outside of the connection sliding rod 17. The two ends of the spring 18 are fixedly connected to the inside of the activity slot 12 and one end of the positioning plug 15 respectively. A tooth block 16 is provided on the outside of the positioning plug 15. The tooth block 16 is meshed with the gear 14. A positioning slot 31 is opened on the outside of the connection plug 3. One end of the positioning plug 15 is movably connected to the inside of the positioning slot 31; One end of the connection rotating rod 13 penetrates through the mounting base 1 and is located outside the mounting base 1 and is fixedly connected to a fixed circular block 32. An auxiliary component is provided on the outside of the fixed circular block 32. A lifting component 10 is provided at the bottom of the mounting base 1;
[0022] Exhaust gas refers to the toxic and harmful gases discharged by humans in the production and living processes. In order to avoid damage to the human body caused by these gases, ventilation and dispersion are required in a timely manner. However, ventilation cannot be carried out in a sealed space, so machines for auxiliary dispersion will be set up. At the same time, in order to better monitor the exhaust gas content in the space, a detection device will be set up in the space;
[0023] When the existing detection device is not installed on the wall, its height is fixed. However, in order to better carry out detection, the height of the detection device needs to be adjusted according to specific situations. In this way, the detection device needs to be connected to a liftable platform. In order not to add excessive disassembly and assembly time and complexity, a simple and stable connection method is required;
[0024] First, align the connection plug 3 with the connection slot 11 and then insert it. When the connection plug 3 touches the outside of the positioning plug 15 and pushes the positioning plug 15 to move backward, the gear 14 rotates accordingly. At the same time, the spring 18 contracts until the connection plug 3 completely enters the connection slot 11. Then the spring 18 extends and the gear 14 also rotates. One end of the positioning plug 15 is inserted into the positioning slot 31, thus fixing the connection plug 3. In this way, the detection device 2 can be installed on the mounting base 1. When it is necessary to remove the mounting base 1, rotate the fixed circular block 32 to drive the connection rotating rod 13 to rotate, so that the gear 14 rotates accordingly, driving the positioning plug 15 to retreat, and allowing the connection plug 3 to freely enter and exit the connection slot 11;
[0025] The detection device 2 can be stably connected to the installation base 1. At the same time, the connection means is simple and easy to operate, without bringing more operation burden to the staff. When the installation base 1 is placed in a sealed space, its height can be adjusted according to specific situations to better control the overall situation.
[0026] In other embodiments, this embodiment discloses that, as shown in Figure 4 As shown, the auxiliary component includes a groove 33, which is opened on the outer side of the fixed circular block 32. An auxiliary rotating block 34 is movably connected to the outer side of the fixed circular block 32. A convex block 35 is provided on the inner side of the auxiliary rotating block 34, and the convex block 35 is movably inserted into the inner side of the groove 33. Through this design, when it is necessary to rotate the fixed circular block 32, the convex block 35 on the auxiliary rotating block 34 can be aligned with the groove 33 and then inserted, and then the fixed circular block 32 can be turned by applying force to the auxiliary rotating block 34, which is more convenient to use.
[0027] In other embodiments, this embodiment discloses that, as shown in Figure 4 As shown, the convex blocks 35 are symmetrically arranged around the inner side of the auxiliary rotating block 34, and the number of the grooves 33 is the same as that of the convex blocks 35. Through this design, the connection points between the auxiliary rotating block 34 and the fixed circular block 32 can be increased, thereby improving the connection stability. Embodiment
[0028] In other embodiments, this embodiment discloses that, as shown in Figure 2 、 Figure 4 As shown, it further includes an alternative mechanism. The alternative mechanism includes an empty slot 20, which is opened on the back surface of the detection device 2. A fixed rod 4 is movably connected to the inner side of the empty slot 20. An installation slot 41 is opened on the top end surface of the fixed rod 4. A connection slot 21 that is communicated with the empty slot 20 is opened on the top end of the detection device 2. A connecting rod 22 is movably connected to the inner side of the connection slot 21. An L-shaped positioning rod 23 is provided on the side of the connecting rod 22 close to the fixed rod 4. One end of the L-shaped positioning rod 23 is movably inserted into the inner side of the installation slot 41, and one end of the connecting rod 22 penetrates through the detection device 2 and is located outside the top end of the detection device 2 and is fixedly connected to a top sealing plate 24.
[0029] Push the fixed rod 4 into the empty slot 20, and then push the connecting rod 22 downward. The L-shaped positioning rod 23 enters the installation slot 41 to lock the fixed rod 4, and the installation base 1 can be stably connected to the fixed rod 4. The fixed rod 4 can be fixedly connected to any wall or platform. When it is necessary to install the installation base 1 on the wall for work, it can be more conveniently connected to the wall, and at the same time, the state is stable, which can enhance the use flexibility of the installation base 1.
