[0002] A gas alarm is a gas leak detection alarm instrument. When flammable or toxic gas leaks in an industrial environment and the gas alarm detects that the gas concentration has reached the critical point set by the explosion or poisoning alarm, the alarm will send out an alarm signal to remind workers to take safety measures and drive the exhaust, cut-off, and spray systems to prevent explosions, fires, and poisoning accidents, thereby ensuring safe production.

[0003] According to a gas alarm capable of wireless alarm with publication number CN219105586U, the gas alarm capable of wireless alarm fixes the gas alarm body by a fixing plate and fixing bolts, a warning light is fixedly installed on the outer side of the gas alarm body, a display is fixedly installed on the upper surface of the gas alarm body, and mounting holes are evenly opened on the side of the mounting frame. The warning light can be used to flash a reminder in time when the detection module detects abnormal gas, and the working status of the gas alarm capable of wireless alarm can be displayed in real time through the display.

[0004] In the above patent, the display is exposed to the outside world. When the display is hit by the outside world, the impact force can easily cause damage to the display screen, making the display of the gas alarm unusable and affecting its service life. Utility Model Content

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

[0013] 1. When the gas alarm is operated, the protective cover, the protective window and the connecting block are rotated with the fixed frame as the axis. The rotation of the connecting block drives the rotating shaft to push the connecting frame to descend. The descent of the connecting frame pushes the connecting rod to descend. The connecting rod pushes the connecting pipe to extend and deform. The connecting pipe rotates on the outside of the support frame. After the protective cover is opened, the gas alarm is controlled by the control display to operate. After the operation is completed, the protective cover is released, the connecting pipe loses the limit and resets. The connecting pipe pushes the connecting rod to rise. The connecting rod pushes the connecting block, the protective cover and the protective window to rotate, so that the protective cover fits with the top of the protective ring. The control display of the gas alarm is protected by the protective cover and the protective window, thereby ensuring that the control display is not physically damaged, reducing the risk of damage, and thus reducing maintenance costs.

[0014] 2. When the detection direction of the gas alarm is adjusted, the fixing plate and the support rod are driven to rise through the machine body, and the support rod pushes the second spring to perform compression deformation. At the same time, the limit hole and the limit rod are separated. After the machine body is rotated to the required angle, the machine body is released, the second spring loses the limit and is reset. The second spring pushes the support rod, the fixing plate, the machine body and the limit hole to descend, so that the limit hole and the limit rod are engaged, and the detection angle of the gas alarm is fixed by the limit hole and the limit rod. By arranging the connecting plate, the limit rod, the fixing tube, the support rod, the second spring and the limit hole, the detection direction of the gas alarm is easy to adjust, thereby improving the application range of the gas alarm and providing convenience for the operator.
