Description

Technical Field

[0001] The utility model relates to the technical field of combustible gas detection, in particular to a combustible gas detection alarm for safety acceptance evaluation. Background Art

[0002] The combustible gas detection alarm used for safety acceptance evaluation is a very important device. It is used to monitor the concentration of combustible gases in the environment. Once the gas concentration exceeds the safe range, an alarm will be issued to ensure the safety of personnel and equipment. It can also monitor the concentration of combustible gases in the environment in real time and transmit the data to the monitoring system or operator to take timely response measures.

[0003] However, in the prior art, some existing combustible gas detection alarms usually have reserved holes drilled in the wall where they need to be installed when the staff install the equipment, and then fix the equipment to the wall with tools and bolts. This method does not require the use of appropriate tools to remove the nuts that fix the instrument before adjusting the position of the instrument. When the equipment needs to be fine-tuned for use in experiments, if the height of the instrument cannot be adjusted directly, it is necessary to drill holes in the wall again. Frequent removal of nuts may cause thread wear or damage, which in turn affects the stability of the fixings and may even damage the instrument itself or the wall, reducing the reliability and durability of the installation, while also increasing the difficulty and time cost of the experiment. Utility Model Content

[0028] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a combustible gas detection alarm for safety acceptance evaluation, comprising: an adjusting mechanism 1, the adjusting mechanism 1 comprises a mounting frame 11, a fixing mechanism 2 is arranged on one side of the mounting frame 11, a handle 12 is arranged on the inner wall of a slot opened at the bottom of the mounting frame 11, a threaded rod 13 is arranged at one end of the handle 12, a fixing ring 14 is arranged on the surface of the other end of the threaded rod 13, a nut 15 is arranged on the surface of the threaded rod 13, a threaded column 16 is arranged on the surface of the nut 15, a threaded tube 17 is arranged on the surface of the threaded column 16, an instrument 18 is arranged at one end of the threaded tube 17, a detection probe 19 is arranged at the bottom of the instrument 18, an alarm component 110 is arranged on the top of the instrument 18, sliders 111 are arranged on the inner walls of the slide grooves opened on both sides of the mounting frame 11, and a connecting frame 112 is arranged on one side of the two sliders 111.

[0029] In this embodiment, the inner wall of the card slot opened at the bottom of the mounting frame 11 is rotatably connected to the surface of the handle 12, one end of the handle 12 is fixedly connected to one end of the threaded rod 13, the other end surface of the threaded rod 13 is rotatably connected to the inner wall of the fixing ring 14, one side of the fixing ring 14 is fixedly connected to the top of the inner wall of the mounting frame 11, the surface of the threaded rod 13 is threadedly connected to the inner wall of the nut 15, the surface of the nut 15 is fixedly connected to one end of the threaded column 16, the surface of the threaded column 16 is threadedly connected to the inner wall of the threaded tube 17, and one end of the threaded tube 17 is fixedly connected to the instrument 18; compared with the traditional method of directly mounting the instrument 18 on the wall by bolts, this method does not need to be adjusted when adjusting the position of components such as the instrument 18. It is necessary to use appropriate tools to first remove the nut 15 that fixes the instrument 18 before the position of the instrument 18 can be readjusted. There is no need to use additional tools or remove the fixing nut 15. The position can be adjusted by turning the handle 12, which not only saves cumbersome steps and improves the adjustment efficiency, but also drives the threaded column 16 and the instrument 18 and other components to move synchronously. The position change during the adjustment process is more precise, and the position of the instrument 18 can be accurately controlled to ensure the accuracy of monitoring. At the same time, this adjustment mechanism is suitable for various scenarios and environments. Whether it is a wall, a ground or other platform, it can be used flexibly and has strong versatility and applicability.

[0030] The bottom of the meter 18 is connected to one end of the detection probe 19, and the top of the meter 18 is connected to one end of the alarm component 110. The inner walls of the slide grooves opened on both sides of the mounting frame 11 are slidably connected with sliders 111, and one side of the two sliders 111 is fixedly connected to a connecting frame 112, and the two connecting frames 112 are respectively threadedly fixed to the two sides of the meter 18 by bolts; there is no need to completely fix the meter 18 and the bracket in advance, but by aligning the threaded tube 17 and the threaded column 16, and then adjusting the position of the slider 111 and fixing it, the entire installation process is not only simpler and faster, but the movement of the slider 111 can also assist in adjusting the position of the meter 18, and at the same time, it can also provide additional support and stability during the movement of the meter 18, reducing movement and looseness caused by vibration or other factors. Example

[0031] like Figure 1-Figure 2 As shown, the fixing mechanism 2 includes a mounting plate 21 , and the mounting plates 21 are fixedly connected to both the top and bottom sides of the mounting frame 11 , and the inner walls of the threaded grooves formed on the plurality of mounting plates 21 are threadedly connected to fixing members 22 .

[0032] In this embodiment, through the cooperation of the above components, the combination of the threaded groove and the fixing piece 22, the mounting plate 21 can not only be firmly fixed on the wall, ensuring that the connection between the mounting frame 11 and the wall is firm and reliable, and not easily loosened or moved due to external forces, but the setting of the reserved holes makes the installation process easier. The staff only needs to rotate the fixing piece 22 to the reserved hole position, and then complete the fixation through threaded connection, eliminating the step of using a large number of bolts and nuts 15 in the traditional installation method, thereby improving the installation efficiency. At the same time, this installation method is suitable for various types of walls, including brick walls, concrete walls, etc., and has strong versatility and applicability, and can meet the installation requirements of different scenarios.

[0033] Working principle:

[0034] like Figure 1-Figure 4 As shown, when the staff installs it, they can first align the threaded tube 17 and the threaded column 16 connected to the instrument 18, and then rotate the instrument 18 to form a limit by threading the threaded connection between the threaded tube 17 and the threaded column 16. After installation, move the slider 111 to a suitable position, and finally use bolts to threadably fix the connecting frame 112 and the instrument 18. In this way, when adjusting the position of the instrument 18, the slider 111 will also assist its movement, thereby increasing the stability of the instrument 18 during movement. When the staff needs to adjust the position of the instrument 18, they can first rotate the handle 12. When the handle 12 rotates, it will synchronously drive the threaded rod 13. The threaded rod 13 will realize rotation by cooperating with the inner wall of the fixing ring 14. When the threaded rod 13 rotates, the thread on its surface will cooperate with the thread groove on the inner wall of the nut 15, thereby realizing the up and down adjustment of the nut 15. When the nut 15 is adjusted up and down, it will synchronously drive the threaded column 16 and the instrument 18 and other components to move synchronously.
