Description

Technical Field

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

[0002] The gas leak detector uses the latest electronic circuits and is specially designed to meet the current and future detection of SF6 gas leakage in various switches, fully enclosed combination electrical appliances and other devices. The instrument test is a qualitative analysis. The operator only needs to turn on the switch, and the leak detector will be programmed to search for multiple gases immediately. When the leaking gas approaches the leak detector, a computer-like alarm will give an alarm signal, and the alarm speed and frequency will increase with the increase in the leakage amount.

[0003] There is a large amount of coal dust in the air in the existing coal mining areas. When the gas leak detector is temporarily idle during the detection of mining equipment, the coal dust will enter the gaps between the buttons on its outer surface and may then enter the inside of the gas leak detector, which will not only cause the buttons to malfunction, but may also affect the normal use of the gas leak detector, greatly reducing the detection efficiency. For this reason, we provide a gas leak detector. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a gas leak detector, comprising: a protective mechanism 1, the protective mechanism 1 comprises a shell 11, a gas leak detector body 13 is provided on one side of the shell 11, a shell 2 12 is sleeved on the outer surface of the shell 11, the shell 2 12 is slidably connected to the shell 11, a clamping block 14 is fixedly connected to the outer surface of the shell 11, a clamping groove 15 matching the clamping block 14 is provided on the shell 2 12, a positioning groove 16 is provided on the outer surface of the shell 11, a slide groove 17 is provided on the outer surface of the shell 11, a slide groove 2 18 is provided on the outer surface of the shell 11, a semicircular block 19 is fixedly connected to the inner wall of the shell 2 12, a semicircular block 2 101 is provided at the bottom of the semicircular block 19, and the semicircular block 2 101 is fixedly connected to the inner wall of the shell 2 12.

[0026] In this embodiment, by setting the protection mechanism 1, when the gas leak detector body 13 is temporarily placed, the gap between the button and the display screen can effectively avoid the contamination of coal dust. At the same time, the shell 11 and the shell 2 12 are tightly connected through the engagement of the clamping block 14 and the clamping groove 15. The positioning groove 16 opened on the shell 11 can play the purpose of positioning and installing when the shell 2 12 is connected to the shell 11, making the connection between the shell 11 and the shell 2 12 easier. In addition, the slide groove 17 and the slide groove 2 18 are connected with the positioning groove 16. 16 is interconnected, so after the semicircular block 19 and the semicircular block 2 101 enter the positioning groove 16, they can finally fit and slide with the slide groove 17 and the slide groove 2 18, and the circumferential diameter of the semicircular block 19 and the semicircular block 2 101 is greater than the circumferential diameter of the block 14. When the inner wall of the shell 2 12 is placed on the top of the block 14, the semicircular block 19 and the semicircular block 2 101 will not be separated from the slide groove 17 and the slide groove 2 18, so that the groove 15 opened on the shell 2 12 can smoothly and tightly fit with the block 14 fixedly connected to the shell 11.

[0027] Example 2

[0028] like Figure 1-Figure 4As shown, an auxiliary mechanism 2 is provided at one end of the gas leak detector body 13, and the auxiliary mechanism 2 includes a fixed block 21, which is fixedly connected to the gas leak detector body 13, and a telescopic rod 22 is sleeved inside the fixed block 21, and the telescopic rod 22 is slidably connected to the fixed block 21. A cross bolt 23 is penetrated inside the telescopic rod 22 and the fixed block 21, and the cross bolt 23 is slidably connected to the telescopic rod 22 and the fixed block 21, and a nut 24 is penetrated on the outer surface of one end of the cross bolt 23, and the nut 24 is threadedly connected to the cross bolt 23.

[0029] In this embodiment, by providing an auxiliary mechanism 2, the gas leak detector body 13 is more convenient to use, can detect a larger area, and can detect special parts of coal mining equipment, thereby improving the practicality of the gas leak detector body 13. The fixed block 21 and the telescopic rod 22 are detachable, and thus will not affect the carrying of the gas leak detector body 13. In addition, a cross bolt 23 and a nut 24 are provided to make the connection between the telescopic rod 22 and the fixed block 21 more stable and easier to release the connection.

[0030] Working principle:

[0031] like Figure 1-Figure 4 As shown, when the utility model is in use, the telescopic rod 22 can be first inserted into the fixed block 21, and the cross bolt 23 and the nut 24 are used to tightly connect the telescopic rod 22 and the fixed block 21, and the telescopic rod 22 is extended and retracted, so that the gas leak detector body 13 can reach a more special position. When the gas leak detector body 13 is temporarily idle, the shell 11 in the protective mechanism 1 can be connected with the shell 2 12, and one end of the semicircular block 19 fixedly connected to the shell 2 12 is first sleeved with the shell 11, and the semicircular block 19 is positioned and installed with the positioning groove 16, so that the semicircular block 19 can slide in the positioning groove 16, and then the shell 2 12 is continuously pushed, so that the semicircular block 19 gradually approaches the slide groove 2 18. At the same time, the semicircular block 101 will also slide in the positioning groove 16 until the semicircular block 19 is placed at the end of the positioning groove 16 close to the slide groove 18. At this time, the semicircular block 101 will be placed at the end of the slide groove 17, and then the shell 12 is pressed. Driven by the shell 12, the semicircular block 19 and the semicircular block 101 will slide into the slide groove 18 and the slide groove 17 respectively, and continue to slide in the slide groove 18 and the slide groove 17 until the shell 12 contacts the block 14. When the semicircular block 19 and the semicircular block 101 cannot slide in the slide groove 18 and the slide groove 17, the block 14 will be tightly engaged with the slot 15 opened on the shell 12, so as to protect the gas leak detector body 13.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
