Description

Technical Field

[0001] The utility model belongs to the technical field of natural gas detectors, and in particular relates to a natural gas leakage detector. Background Art

[0002] Natural gas refers to all gases that exist naturally in nature. A natural gas leak detector is a device specifically used to detect natural gas leaks. It can detect the gas concentration generated after a natural gas leak and remind users to take timely measures through sound and light alarms or other means to avoid danger. When the gas concentration exceeds a certain threshold, the alarm will emit sound and light alarms or other alarm signals to remind users to take timely measures.

[0003] The natural gas detectors currently on the market have the following problems when used:

[0004] 1. When using a traditional detector, the body and the detection probe are connected by a metal hose, and the length of the metal hose is relatively long. Therefore, it is easy to affect the carrying effect during the carrying process due to the long metal hose, and the metal hose without a fixed structure is easy to be pulled, so it is not convenient to use;

[0005] 2. Most detectors are often used in handheld mode during application. If the user does not hold it firmly, or the body is hit during testing and falls, it is easy to fall to the ground and cause damage. Therefore, the stability when holding is poor. Utility Model Content

[0028] like Figure 1-4 As shown, a natural gas leak detector of the utility model includes a detector body 1 and a metal hose 5. The metal hose 5 is provided on the top of the detector body 1. The outside of the detector body 1 is connected to a protective sleeve 2. The outside of the protective sleeve 2 is installed with a side plate 7. The outside of the side plate 7 is connected to a first clamp ring 8. The first clamp ring 8 is connected to a second clamp ring 9 through a rotating shaft. Due to the installation of the first clamp ring 8 and the second clamp ring 9, it is convenient to store the metal hose 5. Strong magnets 11 are embedded on the inner sides of the first clamp ring 8 and the second clamp ring 9. The strong magnets 11 are symmetrically distributed. A push plate 10 is provided on the outside of the second clamp ring 9. Due to the installation of the strong magnet 11, the closed first clamp ring 8 and the second clamp ring 9 can be adsorbed and fixed.

[0029] The bottom of the protective cover 2 is connected to the U-shaped frame 12, and the number of U-shaped frames 12 is set to two groups. An elastic plate 16 is provided at the bottom of the protective cover 2, and hard plates 15 are installed on both sides of the elastic plate 16. The hard plates 15 are inserted into the U-shaped frame 12. Due to the installation of the elastic plate 16 and the U-shaped frame 12, the detector body 1 can be better held.

[0030] A card slot 14 is provided inside the U-shaped frame 12, and a card block 13 is provided at the bottom of the hard board 15. The card blocks 13 are evenly distributed, and the card blocks 13 are embedded inside the card slot 14. By installing the card block 13 and the card slot 14, it is convenient to fix and install the hard board 15 in the U-shaped frame 12.

[0031] The detector body 1 has an embedding groove 4 on its outside, and the protective cover 2 has a locking ball 3 inside. The locking ball 3 is embedded in the locking groove 14 . The installation of the locking ball 3 and the locking groove 14 facilitates the installation of the protective cover 2 on the outside of the detector body 1 .

[0032] A slot 19 is provided at the top of the protective sleeve 2, an insert plate 18 is embedded in the slot 19, and a protective cover 20 is provided on the top of the insert plate 18. By installing the insert plate 18 and the protective cover 20, not only the detector body 1 can be protected, but also the worn protective cover 20 can be replaced.

[0033] A metal probe 6 is installed at the bottom of the metal hose 5, and a charging port 17 is opened on the outside of the protective cover 2. Due to the installation of the charging port 17, it is convenient for the charger to directly pass through the protective cover 2 for charging.

[0034] The working principle of the natural gas leak detector: When using the natural gas detector, first of all, in order to avoid falling during use and thus affecting the detector body 1, the protective cover 2 is installed on the outside of the detector body 1 before use, and the card ball 3 is installed inside the protective cover 2, so that the protective cover 2 can be fixed. Secondly, in order to facilitate the taking of the detector body 1, a holding structure is installed on the back, and the hard plates 15 on both sides of the elastic plate 16 are first clamped in the U-shaped frame 12. Since the card block 13 is installed inside, it will not get loose. This not only makes it more stable when held, but also is not easy to fall. Then the detection can be carried out. However, in order to better protect the screen, the protective cover 20 is first removed when in use. This In this way, the detection can be carried out. Start the power supply in the detection room, then comb the metal hose 5 so that the metal probe 6 at the bottom can be used for detection. After the use of the detector body 1 in the hands of the staff, in order to store the longer metal hose 5 without affecting the carrying effect, a clamping and fixing structure is installed on the side. First, push the push plate 10 on the side of the second clamp plate, and then clamp the metal hose 5 into the inside of the first clamp ring 8. Then close the second clamp ring 9 by rotating the rotating shaft, so that the side of the metal hose 5 is embedded with a strong magnet 11 for adsorption and fixation. In this way, the metal hose 5 is fixed by a fixed structure and is prevented from being pulled. Therefore, it is more convenient to use. When it is needed next time, the second clamp ring 9 is rotated in the opposite direction to take out the metal hose 5 inside it.
