Description

Technical Field

[0001] This utility model relates to the field of gas analysis technology, specifically to a portable gas analyzer. Background Technology

[0002] A gas analyzer is a process analysis instrument used to measure the composition of gases. In many production processes, especially those involving chemical reactions, automatic control based solely on physical parameters such as temperature, pressure, and flow rate is often insufficient. Due to the wide variety of gases being analyzed and the diverse analytical principles, there are many types of gas analyzers, commonly including thermal conductivity gas analyzers, electrochemical gas analyzers, and infrared absorption analyzers. Because of the different detection locations, gas analyzers often need to be carried to different locations for use, thus requiring portability.

[0003] A portable gas analyzer with publication number CN222212708U includes a housing. A display is located at the left end of the housing, and a control button is located at the lower left end. Two symmetrically distributed protective doors are hinged to the left end of the housing, and a sealing strip is fixedly connected between each of the two protective doors, with the two sealing strips in contact with each other. A handle is fixedly connected to the left end of each protective door. An auxiliary limiting mechanism is provided on the housing. By adding a shoulder strap, a winding roller, and a limiting disc to the housing, the length of the shoulder strap can be adjusted by rotating the winding roller when carrying the gas analyzer. After the shoulder strap length is adjusted, it can be carried by hand or on the back, making the analyzer easier to carry. Furthermore, the limiting disc can limit the length of the shoulder strap, making the device more convenient to use.

[0004] The aforementioned device has some defects in its use. The display position is relatively fixed and cannot be adjusted according to usage needs. In actual operation, the analyzer is usually placed on the ground or table, and its display position is not in a convenient position for the operator, which leads to situations such as bending over or squatting when using it, making it inconvenient to adjust and use. In addition, the device only has a handle on the top, and it can only be pulled by the top handle when carrying and moving it. The operation method is relatively simple and inconvenient. Moreover, there is no rolling structure, which makes it inconvenient to adjust the position in a small range. Utility Model Content

[0005] The purpose of this invention is to provide a portable gas analyzer that solves the problems of inconvenient observation and use, and limited handling and adjustment methods in existing instruments.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a portable gas analyzer, comprising a housing, an operation panel is provided on one side of the top of the housing at an angle to the bottom, a triangular fixing plate is rotatably connected to both sides of the operation panel, a pressing plate is slidably connected to the top of the housing near the operation panel, rollers are rotatably connected to the top and bottom of the side wall of the housing away from the operation panel, and a groove is provided at the center of the top of the housing.

[0007] The control panel has a display panel installed inside, an arc-shaped toothed plate is fixedly connected to the top of the control panel, and sliding grooves are provided on both sides of the control panel.

[0008] One side of the triangular fixing plate is fixedly connected to the inclined surface of the box body, and a rectangular hole is opened inside the side of the triangular fixing plate away from the box body, and a threaded rod is inserted through the rectangular hole;

[0009] The extrusion plate is slidably connected to the top of the box, and the end of the extrusion plate near the operating plate is bent towards the bottom. A compression spring is provided at the bottom end of the extrusion plate.

[0010] Preferably, the connecting toothed plate is engaged with one side of the arc-shaped toothed plate, and a receiving groove is provided on the top of the box near the bottom of the extrusion plate. Both sides of the top of the operating plate are rotatably connected to the inside of the triangular fixing plate through a rotating shaft. The extrusion plate is equipped with a connecting toothed plate on the side near the operating plate, and the connecting toothed plate is engaged with the arc-shaped toothed plate.

[0011] Preferably, a slider is slidably connected inside the groove, one end of the threaded rod passes through the rectangular hole and is fixedly connected to the slider, and a fixing nut is threadedly connected to the outer wall of the threaded rod.

[0012] Preferably, one end of the compression spring is fixedly connected to the inner sidewall of the receiving groove, and the end of the compression spring away from the receiving groove is fixedly connected to the sidewall of the bottom bend of the compression plate.

[0013] Preferably, a pull groove is provided at the center of both sides of the box body, and multiple connecting pipes are installed at the bottom of the side wall of the box body near the operation panel, with a handle fixedly connected at the center of the groove.

[0014] Preferably, anti-slip blocks are fixedly installed on both sides of the bottom of the end of the box near the operation panel, and rollers corresponding to the rollers are opened at the top and bottom corners of the side of the box away from the operation panel, and arc grooves are installed inside the rollers.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. Pull the handle in the groove at the top to lift the entire device for easy carrying and movement. Alternatively, insert your hands into the pull slots on both sides of the case for easy lifting and carrying. During use, ensure the rollers and anti-slip blocks are in contact with the ground or tabletop to prevent displacement. To adjust the position, easily lift the end of the case near the anti-slip blocks, bringing the two rollers on one side into contact with the ground or tabletop, allowing you to easily rotate the rollers and adjust the case's position. The case can also be tilted to bring all four rollers on one side into contact with the ground, allowing for direct movement and position adjustment without manual handling, thus improving portability.

[0017] 2. When the operating plate rotates, it drives the arc-shaped toothed plate to rotate as well. After adjusting to the appropriate position, the push on the pressing plate is released, and then the pressing plate can be moved towards one end of the operating plate under the elastic force of the pressing spring. This allows the connecting toothed plate to re-engage with the arc-shaped toothed plate, thus limiting the operation plate and preventing accidental rotation. At the same time, the movement of the operating plate can drive the slider inside the slide groove to move, thereby moving the threaded rod. When fixing is required, the fixing nut can be rotated to press and fit against the triangular fixing plate, thereby fixing the position of the threaded rod and supporting the operating plate. This allows for easy adjustment of the angle of the operating plate. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-5 A portable gas analyzer is shown, comprising a housing 1. An operation panel 2 is inclined from the top to the bottom of the housing 1. Triangular fixing plates 3 are rotatably connected to both sides of the operation panel 2. A compression plate 4 is slidably connected to the top of the housing 1 near the operation panel 2. Rollers 5 are rotatably connected to the top and bottom of the side wall of the housing 1 away from the operation panel 2. A groove 6 is formed at the center of the top of the housing 1. A display panel 201 is installed inside the operation panel 2. An arc-shaped toothed plate 202 is fixedly connected to the top of the operation panel 2. Sliding grooves 203 are formed on both sides of the operation panel 2. One side of the triangular fixing plate 3 is fixedly connected to the inclined surface of the housing 1. A rectangular hole 301 is formed inside the side of the triangular fixing plate 3 away from the housing 1. A threaded rod 302 is inserted through the rectangular hole 301. The compression plate 4 is slidably connected to the top of the housing 1. The end of the compression plate 4 near the operation panel 2 is bent to the bottom. A compression spring 402 is provided at the bottom of the compression plate 4.

[0028] like Figure 4 , Figure 5 As shown, the connecting toothed plate 401 is engaged with one side of the arc-shaped toothed plate 202. The top of the housing 1 is provided with a receiving groove 403 near the bottom of the extrusion plate 4. The top two sides of the operating plate 2 are rotatably connected to the inside of the triangular fixing plate 3 through a rotating shaft. The extrusion plate 4 is equipped with a connecting toothed plate 401 near the operating plate 2, and the connecting toothed plate 401 is engaged with the arc-shaped toothed plate 202. One end of the extrusion spring 402 is fixedly connected to the inner side wall of the receiving groove 403, and the end of the extrusion spring 402 away from the receiving groove 403 is fixedly connected to the side wall of the bottom bend of the extrusion plate 4. Moving the extrusion plate 4 releases the engagement between the connecting toothed plate 401 and the arc-shaped toothed plate 202, thereby facilitating the rotation of the operating plate 2 and adjusting the angle of the operating plate 2. At the same time, when the operating plate 2 rotates, it can drive the arc-shaped toothed plate 202 to rotate as well.

[0029] like Figure 1 , Figure 5As shown, a slider is slidably connected inside the slide groove 203. One end of the threaded rod 302 passes through the rectangular hole 301 and is fixedly connected to the slider. A fixing nut 303 is threadedly connected to the outer wall of the threaded rod 302. When the operating plate 2 moves, it can drive the slider inside the slide groove 203 to move, thereby causing the threaded rod 302 to move. When it is necessary to fix it, the fixing nut 303 can be rotated so that the fixing nut 303 is pressed and fitted with the triangular fixing plate 3, thereby fixing the position of the threaded rod 302 and thus supporting the operating plate 2.

[0030] like Figure 3 , Figure 4 As shown, a pull groove 102 is provided at the center of both sides of the box body 1. Multiple connecting pipes 101 are installed at the bottom of the side wall of the box body 1 near the operation panel 2. A handle 601 is fixedly connected to the center of the groove 6. Pulling the handle 601 in the groove 6 at the top can lift the entire device for easy carrying and movement. At the same time, according to the needs of use, both hands can be inserted into the pull grooves 102 on both sides of the box body 1 to facilitate lifting the box body 1 for carrying.

[0031] like Figure 1 , Figure 4 As shown, anti-slip blocks 501 are fixedly installed on both sides of the bottom of the end of the box 1 near the operation panel 2. Rollers 503 corresponding to rollers 5 are provided at the top and bottom corners of the side of the box 1 away from the operation panel 2. The rollers 503 have arc grooves 502 installed inside, so that the rollers 5 and anti-slip blocks 501 contact the ground or tabletop, thereby preventing the box 1 from shifting. When the position needs to be adjusted, the end of the box 1 near the anti-slip blocks 501 can be easily lifted, so that the two rollers 5 on one side of the box 1 contact the ground or tabletop, so that the box 1 can be pushed to make the rollers 5 rotate, thereby facilitating the displacement adjustment of the box 1. The box 1 can also be tilted to adjust the position, so that all four rollers 5 on one side of the box 1 contact the ground, thereby directly pushing the box 1 to move.

[0032] In use, the handle 601 in the groove 6 at the top can be easily pulled to lift the entire device for easy carrying and movement. Alternatively, the hands can be inserted into the pull slots 102 on both sides of the box 1 to easily lift and carry it. During use, the rollers 5 and anti-slip blocks 501 can be in contact with the ground or tabletop to prevent displacement of the box 1. When adjustment is needed, the end of the box 1 closest to the anti-slip blocks 501 can be easily lifted, causing the two rollers 5 on one side of the box 1 to contact the ground or tabletop, making it easy to push the box 1 to rotate the rollers 5 and adjust the displacement of the box 1. The box 1 can also be tilted to adjust its position, so that all four rollers 5 on one side of the box 1 are in contact with the ground, allowing direct movement of the box 1 for easy position adjustment without manual handling, thus improving portability.

[0033] When the device is in use, the gas to be detected can be connected to the connecting pipe 101 through a conduit, and then the gas can be injected into the detection structure inside the housing 1 to analyze its gas composition. The results are then displayed on the display panel 201. When the angle of the display panel 201 needs to be adjusted, the fixing nut 303 can be easily released, and the pressing plate 4 can be moved to release the engagement between the connecting toothed plate 401 and the arc-shaped toothed plate 202, thus facilitating the rotation of the operating plate 2 to adjust its angle. Simultaneously, the rotation of the operating plate 2 causes the arc-shaped toothed plate 202 to rotate accordingly. Once the desired position is reached, the pushing of the pressing plate 4 is released, thereby releasing the elastic force of the pressing spring 402. The pressure plate 4 moves towards one end of the operating plate 2, thereby re-engaging the connecting toothed plate 401 with the arc-shaped toothed plate 202, thus limiting the operation plate 2 and preventing accidental rotation. At the same time, the movement of the operating plate 2 can drive the slider inside the slide groove 203 to move, thereby moving the threaded rod 302. When fixation is required, the fixing nut 303 can be rotated, causing the fixing nut 303 to press and fit against the triangular fixing plate 3, thereby fixing the position of the threaded rod 302 and thus supporting the operating plate 2. With the operating plate 2, which is easy to adjust the angle, users can easily observe the display panel 201 from different positions and angles, making it more convenient and faster to operate the operating plate 2.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
