Description

Technical Field

[0001] This utility model relates to the field of gas detector technology, and in particular to a portable gas detector. Background Technology

[0002] A gas detector is an instrument used to detect the concentration of leaked gases. These include portable gas detectors, handheld gas detectors, stationary gas detectors, and online gas detectors. They primarily utilize gas sensors to detect the types of gases present in the environment; gas sensors are used to detect the composition and concentration of gases.

[0003] Existing portable gas detectors are usually placed in pockets, hung on the body by a rope, or fixed to the body. Gas detectors placed in pockets are inconvenient to use; gas detectors hung on the body by a rope are prone to accidental activation; gas detectors fixed to the body are not convenient to take out or operate. Therefore, there is a need for a gas detector that is both portable and easy to operate. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a portable gas detector whose body can be adjusted on the human body via a sleeve mounted on a fixed plate. This allows the gas detector to be adjusted to an angle that is easy to carry and operate, making it convenient to carry and use. The invention is simple, efficient, safe, reliable, and easy to operate.

[0005] This utility model is achieved through the following technical solution: a portable gas detector is provided, including a fixing plate fixed to a human body by a fixing device; a sleeve is mounted on the side of the fixing plate away from the human body, the body of the gas detector is fixed on the sleeve, and the operating end of the gas detector is located on the side of the sleeve away from the fixing plate; by adjusting the angle of the body of the gas detector on the human body by the sleeve mounted on the fixing plate, the gas detector can be adjusted to an angle that is easy to carry and easy to operate, thereby facilitating the carrying and use of the gas detector.

[0006] As an optimization, a groove extending toward the housing is provided on the fixed plate, and the axis of the groove is parallel, intersecting, or not in plane with the rotation axis of the housing; a limiting block is slidably provided in the groove, and a spring is provided in the groove to drive the limiting block to move toward the housing; a limiting groove adapted to the limiting block is provided on the housing, and the movement trajectory of the limiting groove intersects with the movement trajectory of the slider; the rotation angle of the housing and the housing is limited by the limiting block and the limiting groove, which facilitates the carrying and use of the gas detector.

[0007] As an optimization, the limiting grooves are arranged around the rotation axis of the casing, and limiting grooves are respectively set on the left and right sides and the front and rear sides of the rotation axis of the casing; the limiting grooves on the left and right sides and the front and rear sides facilitate the carrying and use of the gas detector.

[0008] As an optimization, multiple sliding grooves are provided on the fixed plate, and the sliding grooves are evenly arranged around the rotation axis of the casing; multiple limiting grooves facilitate a more secure limitation of the rotation angle of the casing and the body, making it easier to carry and use the gas detector.

[0009] As an optimization, magnetic material A is fixed on the left and right sides of the fixing plate, and magnetic material B, which is attracted to magnetic material A, is fixed on the left and right sides of the casing, with magnetic material A located on the movement trajectory of magnetic material B; the magnetic materials A and B increase the force of fixing the casing when carrying the gas detector, preventing the casing and casing from rotating during the carrying process.

[0010] The beneficial effects of this utility model are as follows: By adjusting the angle of the gas detector body on the human body through the sleeve mounted on the fixed plate, the gas detector can be adjusted to an angle that is easy to carry and operate, thus facilitating the carrying and use of the gas detector; the rotation angle of the sleeve and the body is limited by the limiting block and the limiting groove, facilitating the carrying and use of the gas detector; the limiting grooves on the left and right sides and the front and rear sides facilitate the carrying and use of the gas detector; the multiple limiting grooves provide a more secure limitation of the rotation angle of the sleeve and the body, facilitating the carrying and use of the gas detector; the magnetic materials A and B increase the force of fixing the sleeve when carrying the gas detector, preventing the sleeve and the body from rotating during carrying.

[0018] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0019] like Figures 1-5 The portable gas detector of this utility model includes a fixing plate 2 fixed to a human body via a fixing device 1; a sleeve 4 is mounted on the side of the fixing plate 2 away from the human body, the body 5 of the gas detector is fixed on the sleeve 4, and the operating end of the gas detector is located on the side of the sleeve 4 away from the fixing plate 2; the fixing plate 2 is fixed to the outside of the forearm of the human body via the fixing device 1, and a rotating shaft 3 with an axis perpendicular to the fixing plate 2 is mounted on the fixing plate 2; the sleeve 4 is fixed to the rotating shaft 3 or the sleeve 4 is mounted on the rotating shaft 3, and the axis of the rotating shaft 3 is perpendicular to the sleeve 4.

[0020] The gas detector body 5 is fixed to the sleeve 4, and the fixing plate 2 is fixed to the human body through the fixing device 1. Rotating the sleeve 4 on the fixing plate 2 causes the sleeve 4 to rotate the body 5 until the axis of the sleeve 4 is parallel to the axis of the fixing plate 2, and the body 5 is in a position that is easy to carry. Continuing to rotate the sleeve 4 on the fixing plate 2 causes the sleeve 4 to rotate the body 5 until the axis of the sleeve 4 is perpendicular to the axis of the fixing plate 2, and the body 5 is in a position that is easy to operate.

[0021] like Figure 1 , Figure 2 and Figure 3 The fixed plate 2 shown has a sliding groove 201 extending toward the sleeve 4. The axis of the sliding groove 201 is parallel, intersecting, or not in plane with the rotation axis of the sleeve 4. A limiting block 6 is slidably provided in the sliding groove 201, and a spring 7 is provided in the sliding groove 201 to drive the limiting block 6 to move toward the sleeve 4. A limiting groove 401 adapted to the limiting block 6 is provided on the sleeve 4, and the movement trajectory of the limiting groove 401 intersects the movement trajectory of the slider. The axis of the sliding groove 201 is perpendicular to the fixed plate 2. The side of the limiting block 6 facing the sleeve 4 is a spherical crown structure, and the center of the spherical crown is located on the axis of the limiting block 6.

[0022] Rotate the sleeve 4 on the fixed plate 2. The sleeve 4 drives the body 5 to rotate. The limiting block 6 moves away from the sleeve 4 along the axial direction of the slide groove 201. The spring 7 contracts, and the limiting block 6 disengages from the limiting groove 401. The limiting groove 401 rotates around the rotation axis of the sleeve 4 to the movement trajectory of the limiting block 6. The spring 7 relaxes, and the limiting block 6 moves towards the sleeve 4 along the axial direction of the slide groove 201 until the limiting block 6 enters the limiting groove 401. The sleeve 4 and the body 5 stop rotating.

[0023] like Figure 3 The limiting grooves 401 shown are arranged around the rotation axis of the sleeve 4, and the limiting grooves 401 are respectively provided on the left and right sides and the front and rear sides of the rotation axis of the sleeve 4; the limiting grooves 401 are evenly arranged around the rotation axis of the sleeve 4.

[0024] Rotate the sleeve 4 on the fixed plate 2. The sleeve 4 drives the body 5 to rotate. The limiting block 6 moves away from the sleeve 4 along the axial direction of the slide groove 201. The spring 7 contracts, and the limiting block 6 disengages from the limiting groove 401. Until the limiting groove 401 rotates around the rotation axis of the sleeve 4 to the designated movement trajectory of the limiting block 6, the spring 7 relaxes, and the limiting block 6 moves towards the sleeve 4 along the axial direction of the slide groove 201 until the limiting block 6 enters the limiting groove 401. The sleeve 4 and the body 5 then stop rotating.

[0025] like Figure 3 Multiple grooves 201 are provided on the fixed plate 2 shown, and the grooves 201 are evenly arranged around the rotation axis of the sleeve 4.

[0026] like Figure 2 and Figure 3 The fixed plate 2 shown has magnetic material A8 fixed on its left and right sides, and the sleeve 4 has magnetic material B9 fixed on its left and right sides, which is attracted to magnetic material A8. Magnetic material A8 is located on the movement trajectory of magnetic material B9. Magnetic material A8 can be a magnet, and magnetic material B9 can be a magnet, iron, etc.

[0027] When the sleeve 4 drives the body 5 to rotate to a position where the axis of the sleeve 4 is parallel to the axis of the fixed plate 2, the magnetic materials A8 and B9 attract each other, and the sleeve 4 is firmly fixed on the fixed plate 2.

[0028] In actual production, the body 5 of the gas detector is fixed to the sleeve 4, and the fixing plate 2 is fixed to the human body through the fixing device 1. When the sleeve 4 is rotated on the fixing plate 2, the sleeve 4 drives the body 5 to rotate. The limiting block 6 moves along the axis of the slide 201 away from the sleeve 4 in the slide 201. The spring 7 contracts, and the limiting block 6 disengages from the limiting groove 401. Until the axis of the sleeve 4 is parallel to the axis of the fixing plate 2, the limiting groove 401 rotates around the rotation axis of the sleeve 4 to the designated movement trajectory of the limiting block 6. The spring 7 is released, and the limiting block 6 moves along the axis of the slide 201 towards the sleeve 4 in the slide 201 until the limiting block 6 enters the limiting groove 401. The sleeve 4 and the body 5 stop rotating, and the body 5 is in a portable position.

[0029] Continue rotating the sleeve 4 on the fixed plate 2. The sleeve 4 drives the body 5 to rotate. The limiting block 6 moves away from the sleeve 4 along the axial direction of the slide groove 201. The spring 7 contracts, and the limiting block 6 disengages from the limiting groove 401 until the axis of the sleeve 4 is perpendicular to the axis of the fixed plate 2. At the same time, the limiting groove 401 rotates around the rotation axis of the sleeve 4 to the designated movement trajectory of the limiting block 6. The spring 7 relaxes, and the limiting block 6 moves towards the sleeve 4 along the axial direction of the slide groove 201 until the limiting block 6 enters the limiting groove 401. The sleeve 4 and the body 5 stop rotating, and the body 5 is in a position that is easy to operate. At the same time, the magnetic materials A8 and B9 attract each other, and the sleeve 4 is firmly fixed on the fixed plate 2.
