Description

Technical Field

[0001] The utility model belongs to the technical field of gas testing, and in particular relates to a portable comprehensive gas tester. Background Art

[0002] A gas detector is an instrument tool for detecting gas leakage concentration. It mainly uses gas sensors to detect the types of gases present in the environment. Gas sensors are sensors used to detect the composition and content of gases. Currently, portable gas detectors are small in size and suitable for carrying in bags.

[0003] However, the air inlet nozzle used for testing of the portable gas detector is in a protruding state as a whole. Therefore, when the detector is packed and carried, the air inlet nozzle is easily squeezed and there is a risk of damage, which makes the safe packaging and carrying of the detector have certain defects. In addition, the portable gas detector is not convenient to be placed upright independently, which requires personnel to hold and keep the air inlet nozzle aligned with the gas to be tested for a long time to perform the test and wait operation during gas detection. Especially when the gas to be detected is harmful, there is a risk of affecting physical health when holding the test results.

[0004] Therefore, a portable comprehensive gas tester is needed to solve the problems in the prior art that the tester is not convenient for safe packaging and carrying and is not convenient for independent erection and use during the test process. Utility Model Content

[0007] It should be noted in the solution that a flip hole is horizontally opened through the surface of the flip bracket, and the locking stud is rotatably connected to the flip hole of the flip bracket.

[0008] It is further worth mentioning that a locking gasket is provided between the flip bracket and the locking knob, and the locking gasket is fixed on an end face of the locking knob close to the locking stud.

[0009] It should be further explained that a distance-adjusting groove is provided on one side surface of the gas tester, and the distance-adjusting sliding block is slidably connected in the distance-adjusting groove of the gas tester.

[0010] As a preferred implementation, a non-slip rubber pad is embedded and fixed on the lower end surface of the flip bracket, and the air inlet end of the air inlet nozzle is tightly attached to the sealing rubber block.

[0011] As a preferred implementation, the inner surface of the flip bracket is attached to the side of the gas tester, and the upper end surface of the flip bracket and the upper surface of the gas tester are on the same horizontal plane.

[0012] As a preferred implementation, a liquid crystal display screen is disposed on the upper surface of the gas tester, and a control button is disposed on the upper surface of the gas tester on one side of the liquid crystal display screen.

[0013] As a preferred implementation, a USB charging port is provided in the middle of the tail end of the gas tester, and a gas detection mechanism is provided inside the gas tester.

[0014] Compared with the prior art, the portable comprehensive gas tester provided by the utility model has at least the following beneficial effects:

[0015] ⑴ Through the setting of the protective mechanism, the flip bracket can be horizontally enclosed on the side of the gas tester to improve the protruding state of the air inlet nozzle, which can improve the safety of the air inlet nozzle of the gas tester during packaging and carrying. The flip bracket can also be adjusted so that the sealing block blocks the USB charging port and plays a role in waterproof and dustproof, so as to adapt to gas testing in different complex application places.

[0016] ⑵ Through the set adjustment mechanism and flip bracket, the opening and closing angle between the flip bracket and the gas tester can be adjusted so that the gas tester can be placed upright. This can save the tedious steps of manual holding and waiting during the gas detection process, thereby adapting to the application scenario where the air inlet nozzle does not need to be held hand when detecting harmful gases.
