Technical Field
[0001] The utility model relates to the technical field of gas detection devices, in particular to a rechargeable portable gas detection alarm. Background Technique
[0002] A gas detection alarm is a device used to monitor and detect the concentration of harmful gases in the environment. Once it detects a gas concentration exceeding a preset threshold, it will emit an alarm to alert people and prompt them to take corresponding safety measures. Many workplaces often need to use gas detectors to ensure the safety of the working environment. For example, in mining and tunnel engineering or construction sites, it is often necessary to detect harmful gases to ensure the safety of workers. However, the sites are usually complex, which easily causes the gas detection alarm to be dropped or bumped, and the dust is relatively large, making the gas detection alarm prone to damage. Moreover, the existing gas detection alarms lack corresponding protection. Therefore, those skilled in the art provide a rechargeable portable gas detection alarm to solve the problems raised in the above background technique. Content of the Utility Model
[0003] The purpose of the utility model is to provide a rechargeable portable gas detection alarm to solve the problems raised in the above background technique.
[0004] To achieve the above purpose, the utility model provides the following technical solutions:
[0005] The rechargeable portable gas detection alarm includes a protective shell and a gas detection alarm body. A sliding cover is slidably installed at the upper end of the protective shell. Three buffer springs are equally spaced and fixedly installed on the inner walls of both sides of the protective shell. The other ends of the buffer springs are fixedly connected to protective plates. A through hole is opened at the upper end of the protective shell. The gas detection alarm body is detachably installed inside the protective shell, and the two side end faces of the gas detection alarm body are in contact with the protective plates.
[0006] As a further solution of the utility model: A threaded pipe is integrally connected to the upper surface of the protective shell above the through hole, and a screw cap is threadedly installed on the outer wall of the threaded pipe.
[0007] As a further solution of the utility model: A detection head is arranged at the upper end of the gas detection alarm body, and the position of the detection head matches that of the through hole.
[0008] As a further solution of the utility model: A rectangular window is opened in the middle of the upper end of the sliding cover, and an acrylic plate is adhered in the rectangular window.
[0009] As a further solution of the utility model: Sliders are fixedly connected to the lower end of the sliding cover near both left and right sides, and the sliders are located in the sliding grooves and are slidably connected to the inner walls of the sliding grooves.
[0010] As a further solution of the utility model: Card slots are centrally formed on the surfaces of the opposite sides of the two sliders.
[0011] As a further solution of the utility model: Spring cavities are formed on the inner walls at both ends of the two sliding grooves, and reset springs are fixedly installed on the inner bottom walls of the spring cavities.
[0012] As a further solution of the utility model: One ends of the reset springs are fixedly connected to connecting rods, and one ends of the connecting rods are fixedly connected to arc ball heads, and the arc ball heads are all located in the sliding grooves.
[0013] Compared with the prior art, the utility model provides a rechargeable portable gas detection alarm, which has the following technical effects and advantages:
[0014] 1. In places such as mine and tunnel projects, construction sites, etc., the dust on-site is relatively large, which easily dirties the detection head of the gas detection alarm, resulting in easy detection errors. The utility model protects the detection head of the gas detection alarm through a rotary cover. When detecting, the rotary cover is unscrewed, and when not in use, the rotary cover is screwed on, so that the rotary cover plays a protective role for the detection head of the gas detection alarm.
[0015] 2. The utility model protects the gas detection alarm body through a protective shell, and the buffer spring and the protection plate can play a role in shock absorption and buffering, and can protect the gas detection alarm body when the gas detection alarm body is collided or dropped.
[0016] 3. The utility model is provided with a sliding cover at the upper end of the protective shell. When using the gas detection alarm body and it is necessary to press the function button on the gas detection alarm body, the sliding cover can be quickly slid open for operation, and the center of the sliding cover is an acrylic plate, which is not only convenient for perspective but also has a certain strength and is resistant to smashing and falling.
