Description

Technical Field

[0001] The utility model relates to the technical field of gas chromatographs, in particular to a detection device for acrylate gases in nitrogen. Background Art

[0002] For a previous gas chromatograph, when it needs to be moved, the moving wheels can be extended by rotating the handwheel. After the moving wheels are extended, the gas chromatograph can be pulled to facilitate its position movement. However, when pulling the gas chromatograph, if the ground is uneven, it is easy to cause the gas chromatograph to jolt, which can easily damage the internal electronic devices and thus affect the service life of the gas chromatograph.

[0003] In the prior art, CN210803376U, a portable gas chromatograph, is provided to solve this technical problem. By safely placing the gas chromatograph body in the placement groove, the shock absorption component effectively absorbs the vibration generated during movement, reduces the damage to the internal electronic devices caused by shaking. At the same time, the anti-disconnection component further stabilizes the instrument body and limits the shaking amplitude. And the built-in buffer spring can not only provide additional buffering for the instrument body, but also avoid hard contact with the groove wall, reducing the potential damage risk. The design of the protective plate and the protective ring can effectively block the intrusion of water and corrosive substances, protecting the shock absorption component and the instrument body from corrosion, thereby improving the service life and stability of the gas chromatograph.

[0004] However, during its use, there may also be certain technical problems. For example, when the device is in use, it is necessary to first release the fixing of the telescopic leg by the locking bolt, and then the telescopic spring pulls the telescopic leg to move upward so that the telescopic leg is located inside the fixed leg, thereby making the moving wheel contact the ground, so as to facilitate the staff to push the gas chromatograph body to the required position. However, since there are four groups of lifting support legs on this device, and a person can only release the fixing of the telescopic leg by the locking bolt on one group of lifting support legs at a time, this may cause the device to be unstable, and the person who needs to disassemble it has to hold the device for auxiliary fixing, which may cause inconvenience to the staff during use. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a detection device for acrylate gases in nitrogen, which can not only move the gas chromatograph body to the required position, but also facilitate the staff to use it.

[0006] The present utility model is achieved through the following technical solutions. A detection device for acrylate gases in nitrogen is provided, which includes a connecting seat and a gas chromatograph body installed in the connecting seat. A moving wheel is installed at the bottom of the connecting seat. A top plate is arranged below the connecting seat. A threaded rod is arranged between the top plate and the connecting seat. The upper end of the threaded rod is rotatably connected to the bottom of the connecting seat. The lower end of the threaded rod passes through the top plate and is threadedly connected to the top plate. A turbine located between the top plate and the connecting seat is sleeved on the outer side wall of the threaded rod. A worm meshing with the turbine and rotatably connected to the bottom of the connecting seat is provided on the turbine. The moving wheel includes two support plates arranged below the top plate. The upper ends of the support plates pass through the top plate and are fixedly connected to the bottom of the connecting seat. The two support plates are distributed along the left-right direction of the connecting seat. A runner is arranged between the two support plates at a position below the top plate. A rotating shaft rotatably connected to the inner side wall of the support plate is coaxially fixedly connected to the runner.

[0007] When the present utility model is in use, by setting the connecting seat and the gas chromatograph body installed in the connecting seat, a moving wheel is installed at the bottom of the connecting seat, and a top plate is arranged below the connecting seat. A threaded rod is arranged between the top plate and the connecting seat. The upper end of the threaded rod is rotatably connected to the bottom of the connecting seat. The lower end of the threaded rod passes through the top plate and is threadedly connected to the top plate. A turbine located between the top plate and the connecting seat is sleeved on the outer side wall of the threaded rod. A worm meshing with the turbine and rotatably connected to the bottom of the connecting seat is provided on the turbine. The moving wheel includes two support plates arranged below the top plate. The upper ends of the support plates pass through the top plate and are fixedly connected to the bottom of the connecting seat. The two support plates are distributed along the left-right direction of the connecting seat. A runner is arranged between the two support plates at a position below the top plate. A rotating shaft rotatably connected to the inner side wall of the support plate is coaxially fixedly connected to the runner. When the device is in use, a force needs to be applied to the device first. The runner rotates around the rotating shaft on the support plate under the action of the force, so as to push the device to the required position. Then, the worm is rotated, so that the worm rotates on the connecting seat and drives the turbine to rotate on the connecting seat, thereby driving the threaded rod to rotate. At this time, since the support plate passes through the top plate and is fixed to the connecting seat, the top plate will not rotate under the drive of the threaded rod, but will be driven to move downward and press against the top of the runner to make it unable to rotate, so as to fix the device at the required position. Then, the gas chromatograph body is used to detect the acrylate gases in nitrogen. After the detection is completed, the worm is rotated in the reverse direction to drive the turbine and the threaded rod to rotate in the reverse direction, so that the top plate returns to the initial position and no longer presses against the top of the runner, and the staff can continue to push the device to move. In this way, not only can the gas chromatograph body be moved to the required position, but also it is convenient for the staff to use.

[0008] Preferably, a rubber pad adapted to the runner is installed at the bottom of the top plate, and anti-slip lines are provided on the rubber pad. By installing a rubber pad adapted to the runner at the bottom of the top plate and providing anti-slip lines on the rubber pad, the fixing effect of the top plate on the runner can be improved by using the rubber pad and the anti-slip lines, and the runner can be prevented from rotating when the device is in use.

[0009] Preferably, a connecting plate is fixedly connected to the bottom of the connecting seat, a second bearing seat is fixedly installed on the connecting plate, and the worm is rotatably connected to the connecting seat through the second bearing seat on the connecting plate. By fixedly connecting a connecting plate to the bottom of the connecting seat, fixedly installing a second bearing seat on the connecting plate, and rotatably connecting the worm to the connecting seat through the second bearing seat on the connecting plate, the stability between the connecting seat and the worm during the use of the device can be improved by using the second bearing seat and the connecting plate, and the worm can be prevented from detaching from the connecting seat when the device is in use.

[0010] Preferably, a first bearing seat is fixedly installed at the bottom of the connecting seat, and the threaded rod is rotatably connected to the connecting seat through the first bearing seat. By fixedly installing a first bearing seat at the bottom of the connecting seat and rotatably connecting the threaded rod to the connecting seat through the first bearing seat, the stability between the connecting seat and the threaded rod during the use of the device can be improved by using the first bearing seat, and the threaded rod can be prevented from detaching from the connecting seat when the device is in use.

[0011] Preferably, a rotating handle is fixedly connected to one end of the worm away from the connecting plate, and the rotating handle is located outside the top plate. By fixedly connecting a rotating handle to one end of the worm away from the connecting plate and the rotating handle being located outside the top plate, the rotating handle can be used to facilitate the rotation of the worm by the staff.

[0012] Preferably, four moving wheels are provided at the bottom of the connecting seat, and the four moving wheels are equidistantly distributed along the circumference of the connecting seat. By providing four moving wheels at the bottom of the connecting seat and making the four moving wheels equidistantly distributed along the circumference of the connecting seat, the stability of the device during movement can be improved.

[0013] The beneficial effects of the present utility model are as follows: By providing a connecting seat and a gas chromatograph body installed in the connecting seat, a moving wheel is installed at the bottom of the connecting seat, and a top plate is provided below the connecting seat. A threaded rod is provided between the top plate and the connecting seat. The upper end of the threaded rod is rotatably connected to the bottom of the connecting seat, and the lower end of the threaded rod passes through the top plate and is threadedly connected to the top plate. A turbine is sleeved on the outer side wall of the threaded rod and is located between the top plate and the connecting seat. A worm meshing with the turbine is rotatably connected to the bottom of the connecting seat. The moving wheel includes two support plates provided below the top plate. The upper ends of the support plates pass through the top plate and are fixedly connected to the bottom of the connecting seat. The two support plates are distributed along the left-right direction of the connecting seat. A rotating wheel is provided between the two support plates and is located below the top plate. A rotating shaft coaxially fixed to the rotating wheel is rotatably connected to the inner side wall of the support plate. When the device is in use, force needs to be applied to the device first. The rotating wheel rotates on the support plate around the rotating shaft under the action of the force, so as to push the device to the required position. Then, the worm is rotated, so that the worm rotates on the connecting seat and drives the turbine to rotate on the connecting seat, thereby driving the threaded rod to rotate. At this time, since the support plate passes through the top plate and is fixed to the connecting seat, the top plate will not rotate driven by the threaded rod, but will be driven to move downward and press against the top of the rotating wheel to make it unable to rotate, so as to fix the device at the required position. Then, the gas chromatograph body is used to detect acrylate gases in nitrogen.

[0020] To clearly illustrate the technical features of this solution, the following will elaborate on this solution through specific implementation manners.

[0021] As Figures 1 - 4 shown, the detection device for acrylate gases in nitrogen of the present utility model includes a connection seat 2 and a gas chromatograph body 1 installed in the connection seat 2. A moving wheel is installed at the bottom of the connection seat 2. A top plate 3 is arranged below the connection seat 2. A threaded rod 13 is arranged between the top plate 3 and the connection seat 2. The upper end of the threaded rod 13 is rotatably connected to the bottom of the connection seat 2. The lower end of the threaded rod 13 passes through the top plate 3 and is threadedly connected to the top plate 3. A turbine 12 located between the top plate 3 and the connection seat 2 is sleeved on the outer side wall of the threaded rod 13. A worm 8 rotatably connected to the bottom of the connection seat 2 is engaged with the turbine 12. The moving wheel includes two support plates 9 arranged below the top plate 3. The upper ends of the support plates 9 pass through the top plate 3 and are fixedly connected to the bottom of the connection seat 2. The two support plates 9 are distributed along the left and right directions of the connection seat 2. A runner 4 located below the top plate 3 is arranged between the two support plates 9. A rotating shaft 6 rotatably connected to the inner side wall of the support plate 9 is coaxially fixedly connected to the runner 4.

[0022] By installing a rubber pad 5 adapted to the runner 4 at the bottom of the top plate 3 and providing anti-slip lines on the rubber pad 5, the rubber pad 5 and the anti-slip lines can improve the fixing effect of the top plate 3 on the runner 4 and prevent the runner 4 from rotating during the use of the device. By fixedly connecting a connecting plate 11 to the bottom of the connection seat 2, fixedly installing a second bearing seat 14 on the connecting plate 11, and rotatably connecting the worm 8 to the connection seat 2 through the second bearing seat 14 on the connecting plate 11, the second bearing seat 14 and the connecting plate 11 can improve the stability between the connection seat 2 and the worm 8 during the use of the device and prevent the worm 8 from detaching from the connection seat 2 during the use of the device. By fixedly installing a first bearing seat 10 at the bottom of the connection seat 2 and rotatably connecting the threaded rod 13 to the connection seat 2 through the first bearing seat 10, the first bearing seat 10 can improve the stability between the connection seat 2 and the threaded rod 13 during the use of the device and prevent the threaded rod 13 from detaching from the connection seat 2 during the use of the device. By fixedly connecting a rotating handle 7 to one end of the worm 8 away from the connecting plate 11 and the rotating handle 7 being located outside the top plate 3, the rotating handle 7 can facilitate the staff to rotate the worm 8. By arranging four moving wheels at the bottom of the connection seat 2 and making the four moving wheels evenly distributed along the circumferential direction of the connection seat 2, the stability of the device during movement can be improved.

[0023] Combined with the attached Figures 1 - 4It can be seen that the usage method of the present utility model is as follows: First, a force needs to be applied to the device first, so that the rotating wheel 4 rotates around the rotating shaft 6 on the support plate 9 under the action of the force, thereby pushing the device to the required position. Then, rotate the rotating handle 7 to drive the worm 8 to rotate in the second bearing seat 14 on the connecting plate 11, and drive the turbine 12 to rotate in the first bearing seat 10 on the connecting seat 2, thereby driving the threaded rod 13 to rotate. At this time, since the support plate 9 passes through the top plate 3 and is fixed to the connecting seat 2, the top plate 3 will not rotate driven by the threaded rod 13, but will be driven to move downward, and the rubber pad 5 will contact the rotating wheel 4, thereby pressing against the top of the rotating wheel 4 to prevent it from rotating, so that the device is fixed at the required position. Then, use the gas chromatograph body 1 to detect the acrylate gas in nitrogen. After the detection is completed, rotate the worm 8 in the reverse direction to drive the turbine 12 and the threaded rod 13 to rotate in the reverse direction, so that the top plate 3 returns to the initial position and no longer presses against the top of the rotating wheel 4, and the staff can continue to push the device to move.
