In addition, the embodiments of the present utility model can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0028] In order to better understand the purpose, structure and function of the utility model, the handheld gas detector of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0029] like Figure 1-5 As shown, a handheld gas detector of the utility model comprises a detector body 1, a fixing frame 7 is welded on the surface of the detector body 1, a shaft rod 8 is welded on the other end of the fixing frame 7, a shaft sleeve 9 is sleeved on the surface of the shaft rod 8, a fixing block 10 is welded on the surface of the shaft sleeve 9, a protective cover 5 is welded on the surface of the fixing block 10, a screen 3 is installed on the surface of the detector body 1, a button 4 is installed on the surface of the detector body 1, a magnet frame 6 is bonded to the surface of the detector body 1, and the iron frame is installed by magnetism. On the premise that the material of the protective cover 5 is metal iron, when the protective cover 5 is closed, it will fit with the magnet frame 6. At this time, the magnetic attraction effect will make the protective cover 5 adsorbed on the magnet frame 6, thereby providing a fixing effect for the protective cover 5, which is very convenient to use. The material of the protective cover 5 is metal iron, and the bottom of the protective cover 5 fits on the magnet frame 6. The screen 3 is located inside the protective cover 5, and the button 4 is located inside the protective cover 5. By installing the protective cover 5, when the handheld gas detector is carried or stored, the protective cover 5 can be used to protect the screen 3 and the button 4, so that they will not be collided and then damaged, and the protectiveness is strong when used.

[0030] A fixing plate 15 is installed at the bottom of the detector body 1, and a side plate 16 is welded on the top of the fixing plate 15. A hole groove 17 is opened on the side of the side plate 16. A soft strip 18 runs through the hole groove 17. One end of the soft strip 18 is fixedly connected to the hanging strap 12, and the other end of the soft strip 18 is adhered to a baffle 19. The side of the baffle 19 is attached to the side plate 16. By installing the hanging strap 12, when the handheld gas detector needs to be carried, the hanging strap 12 can be used to hang the handheld gas detector on a belt or wrist. At this time, it will not occupy the position of the palm, which is very convenient to carry.

[0031] An externally threaded rod 13 is welded to the bottom of the detector body 1, and the externally threaded rod 13 passes through the fixing plate 15. A nut 14 is installed on the surface of the externally threaded rod 13, and the top of the nut 14 is attached to the bottom of the fixing plate 15. The fixing plate 15 can be fixed to the detector body 1 by installing the externally threaded rod 13, using the externally threaded rod 13 to pass through the fixing plate 15, and installing the nut 14 on the externally threaded rod 13. When in use, the fixing plate 15 can be installed and disassembled, which is very convenient to use.

[0032] The protective cover 5 has a soft film 20 bonded inside, and the bottom of the soft film 20 is attached to the surface of the screen 3. By installing the soft film 20, the screen 3 can be protected by the soft film 20, which further improves the protective effect of the screen 3 during use, and has strong protective performance during use.

[0033] The anti-skid pad 11 is bonded to the side of the detector body 1, and the anti-skid pad 11 is symmetrically distributed. By pressing the anti-skid pad 11, the friction between the palm and the detector body 1 can be increased when holding the detector body 1, so that the hand will not slip, and the stability is strong during use.

[0034] The receiver 2 is installed on the surface of the detector body 1, and the external threaded rods 13 are symmetrically distributed. Through the distribution of the external threaded rods 13, when the fixing plate 15 is installed using the external threaded rods 13, the fixing effect of the fixing plate 15 can be further improved, and the stability is stronger during use.

[0035] The working principle of the handheld gas detector is as follows: when using the handheld gas detector, the fixing plate 15 should be installed at the bottom of the detector body 1 first. At this time, the external threaded rod 13 can be passed through the fixing plate 15, and the nut 14 can be installed on the surface of the external threaded rod 13 until one end of the nut 14 fits against the fixing plate 15. At this time, the fixing plate 15 will be fixed. After that, the handheld gas detector can be used. When using it, the protective cover 5 should be opened first. When opening the protective cover 5, the protective cover 5 can be rotated using the shaft 8 as the center. When the handheld gas detector is used, the protective cover 5 can be rotated using the shaft 8 as the center again. The protective cover 5 is fixed to the magnetic frame 6 by the magnetic effect, and the screen 3 and the button 4 can be protected by the protective cover 5 when the handheld gas detector is carried or stored. The protective cover 5 will not be damaged by collision, and the protective cover 5 has strong protection when used. When the handheld gas detector needs to be carried, the handheld gas detector can be hung on the belt or wrist by the hanging strap 12. At this time, the handheld gas detector will not occupy the position of the palm, which is very convenient to carry.

[0036] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
