Description

Technical Field

[0001] This utility model relates to the field of gas chromatography technology, specifically a gas chromatography stationary device. Background Technology

[0002] A gas chromatograph is an instrument used to separate and analyze the components of complex gas mixtures. It uses a gas as the mobile phase (carrier gas), typically helium, nitrogen, or hydrogen. When a sample is injected into the injection port, it vaporizes instantly (if the sample is a liquid or solid). Gas chromatographs are widely used in the petrochemical, pharmaceutical, and food industries, among others.

[0003] Existing gas chromatographs are typically placed on a workbench for support to ensure stability during operation. However, in practice, the fixed height of the workbench, with varying heights among operators, makes it difficult for shorter operators to operate the instrument. This results in obstructed vision or limited operating space, hindering operation and ultimately leading to poor performance. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a gas chromatograph fixing device, which solves the problem that when a gas chromatograph is fixed at a certain height during use, it cannot be flexibly adjusted according to the height of the operator, resulting in obstructed vision or inconvenience in operation, thus affecting the operator's work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gas chromatography stationary device, comprising a support plate, an installation groove on the support plate, a chromatograph body movably connected in the installation groove, a fixing plate below the support plate, a fixing frame fixedly connected to the lower end face of the fixing plate, a forward and reverse motor fixedly connected to the fixing frame, a rotating shaft connected to the output end of the forward and reverse motor, the rotating shaft being rotatably connected to the fixing plate, a screw rod fixedly connected to the end of the rotating shaft away from the forward and reverse motor, an adjusting disc screwed onto the outer wall of the screw rod, a plurality of connecting rods fixedly connected to the upper end face of the adjusting disc, the connecting rods being fixedly connected to the support plate, the plurality of connecting rods being evenly distributed around the axis of the adjusting disc, stabilizing rods fixedly connected to the four corners of the lower pad surface of the support plate, and fixing columns slidably connected to the outer wall of the stabilizing rods.

[0006] The beneficial effects of this utility model are as follows: the installation groove on the upper surface of the support plate can be used to install and fix the chromatograph body, preventing the chromatograph body from shifting randomly. With the operation of the forward and reverse motors, the rotating shaft drives the screw rod to rotate, and the screw rod is screwed to the adjustment plate. This causes the adjustment plate to lift up with multiple connecting rods, allowing the chromatograph body on the support plate to be raised and lowered. This can be flexibly adjusted according to the user's height, improving the flexibility of use, facilitating operation by staff, and improving work efficiency.

[0007] In order to enable flexible movement of the fixed device;

[0008] As a further improvement to the above technical solution: support legs are fixedly connected to the four corners of the lower end face of the fixed plate, and casters are fixedly connected to the lower end face of the support legs;

[0009] The beneficial effects of this improvement are as follows: by using support legs and casters, the fixed plate can be supported, ensuring that the fixed plate remains sufficiently stable during use. Furthermore, by using casters, the fixed plate can be moved flexibly, improving the flexibility of the fixing device.

[0010] In order to fix the position of the fixing device;

[0011] As a further improvement to the above technical solution: two symmetrical electric telescopic columns are fixedly connected to the fixed plate, a stabilizing block is fixedly connected to the movable end of the electric telescopic column, and a rubber block is fixedly connected to the lower end face of the stabilizing block;

[0012] The beneficial effects of this improvement are as follows: by extending the electric telescopic column, the rubber block on the lower end of the stabilizing block moves towards the ground, generating greater friction between the rubber block and the ground, thereby ensuring the stability of the fixing device during use and preventing the fixing device from shifting randomly when stationary.

[0013] In order to limit the movement of the stabilizer bar and ensure the stability of the connection between the stabilizer bar and the fixed post;

[0014] As a further improvement to the above technical solution: a groove is provided inside the fixed column, and a slider is slidably connected inside the groove, and the slider is fixedly connected to the stabilizer rod;

[0015] The beneficial effects of this improvement are as follows: by using the slide groove and slider, the stabilizer bar can be raised and lowered flexibly while being limited to prevent it from separating from the fixed column, thus ensuring the stability of the sliding between the stabilizer bar and the fixed column.

[0016] In order to guide the stable block;

[0017] As a further improvement to the above technical solution: two symmetrical guide rods are fixedly connected to the upper end face of the stabilizing block, and the guide rods are slidably connected to the fixed plate;

[0018] The beneficial effects of this improvement are: by using the guide rod, the stabilizing block can be guided, ensuring that the stabilizing block maintains a vertical movement trajectory during the lifting and lowering process, without tilting or swaying, and allowing the stabilizing block and rubber block to make stable contact with the ground.

[0019] In order to increase the friction of the rubber block;

[0020] As a further improvement to the above technical solution: the lower end face of the rubber block is provided with multiple evenly distributed grooves;

[0021] The beneficial effects of this improvement are: by using grooves, the friction between the rubber block and the ground can be increased, thereby assisting the rubber block and the stabilizing block in fixing the position of the fixing plate and ensuring sufficient stability of the gas chromatograph during use.

[0022] In order to control the direction of movement of the fixed device;

[0023] As a further improvement to the above technical solution: a handle is fixedly connected to one side of the support plate;

[0024] The beneficial effects of this improvement are: the use of handles allows for flexible control of the fixing plate and support plate, making it easier for workers to move the fixing device.

[0025] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. Attached Figure Description

Detailed Implementation

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0033] like Figures 1 to 5As shown in the figure, the gas chromatography stationary device provided in this embodiment includes a support plate 1 with a mounting groove 11. A chromatograph body 12 is movably connected in the mounting groove 11. The chromatograph body 12 can be fixed in place by the mounting groove 11 on the upper surface of the support plate 1, ensuring sufficient stability of the chromatograph body 12 and preventing arbitrary displacement. A fixing plate 13 is provided below the support plate 1. A fixing frame 14 is fixedly connected to the lower surface of the fixing plate 13. A forward and reverse motor 15 is fixedly connected to the fixing frame 14, which can fix the forward and reverse motor 15 and ensure stable output of the forward and reverse motor 15. A rotating shaft 16 is connected to the output end of the forward and reverse motor 15. The rotating shaft 16 is rotatably connected to the fixing plate 13. The rotating shaft 16 is located away from the forward and reverse motor 15. A screw rod 17 is fixedly connected to one end of the support plate 1. An adjusting disc 18 is screwed onto the outer wall of the screw rod 17. Multiple connecting rods 19 are fixedly connected to the upper surface of the adjusting disc 18. The connecting rods 19 are fixedly connected to the support plate 1. The multiple connecting rods 19 are evenly distributed around the axis of the adjusting disc 18. Under the operation of the forward and reverse motor 15, the rotating shaft 16 drives the screw rod 17 to rotate and is screwed onto the adjusting disc 18. This causes the adjusting disc 18 to lift and lower the four connecting rods 19, allowing for flexible lifting and lowering of the chromatograph body 12 on the support plate 1. Stabilizing rods 20 are fixedly connected to the four corners of the lower surface of the support plate 1. Fixed posts 21 are slidably connected to the outer wall of the stabilizing rods 20. The four stabilizing rods 20 slide on their respective fixed posts 21, which can limit the position of the support plate 1 and ensure support. The plate 1 is stable during lifting and lowering, without tilting or swaying. Support legs 31 are fixedly connected to the four corners of the lower end face of the fixed plate 13, and casters 32 are fixedly connected to the lower end face of each support leg 31. The four support legs 31 and their corresponding casters 32 provide support for the fixed plate 13, ensuring its stability. The casters also allow for flexible movement of the fixing device. Two symmetrical electric telescopic columns 41 are fixedly connected to the fixed plate 13. A stabilizing block 42 is fixedly connected to the movable end of each electric telescopic column 41, and a rubber block 43 is fixedly connected to the lower end face of each stabilizing block 42. The extension of the two electric telescopic columns 41 moves their respective stabilizing blocks 42 and rubber blocks 43 downwards, bringing the rubber blocks 43 into contact with the ground and increasing friction. The rubber block 43 has multiple evenly distributed grooves 71 on its lower end face. These grooves increase the friction of the rubber block 43, ensuring the fixing device remains stationary. A sliding groove 51 is provided inside the fixing post 21, and a slider 52 is slidably connected within it. The slider 52 is fixedly connected to the stabilizer rod 20. The four sliders 52 slide within their respective sliding grooves 51, limiting the stabilizer rod 20 and preventing it from detaching from the fixing post 21 during lifting and lowering. Two symmetrical guide rods 61 are fixedly connected to the upper end face of the stabilizing block 42. These guide rods 61 are slidably connected to the fixing plate 13.The stabilizer block 42 can be guided to ensure that it maintains a vertical movement trajectory during lifting and lowering. A handle 81 is fixedly connected to one side of the support plate 1. The handle 81 allows for control of the movement direction of the fixing device, facilitating operation by the staff.

[0034] The working principle and usage process of this utility model are as follows: First, by using the handle 81 and four universal wheels 32, the fixing device can be moved to the desired position. With the extension of the two electric telescopic columns 41, the corresponding stabilizing blocks 42 and rubber blocks 43 move towards the ground, generating significant friction between the rubber blocks 43 and the ground, thus securing the fixing device. When adjustment is needed, the rotating shaft 16 rotates under the action of the forward and reverse motors 15, causing the screw rod 17 to connect with the adjusting disc 18. This allows the adjusting disc 18 to raise and lower along with the four connecting rods 19. The raising and lowering of the connecting rods 19 flexibly raises and lowers the chromatograph body 12 on the support plate 1. The four stabilizing rods 20 slide on their respective fixing columns 21, guiding and limiting the support columns to ensure sufficient stability of the support plate 1 and prevent tilting or swaying. This completes the usage process of the gas chromatograph fixing device.
