Description

Technical Field

[0001] This utility model relates to the field of gas chromatograph technology, specifically a gas chromatograph with a protective outer shell. Background Technology

[0002] Gas chromatography is an instrument that uses chromatographic separation and detection techniques to perform qualitative and quantitative analysis of complex mixtures of multiple components. It is typically used to analyze thermally stable organic compounds in soil with boiling points not exceeding 500℃, such as volatile organic compounds, organochlorines, organophosphorus compounds, polycyclic aromatic hydrocarbons, and phthalates.

[0003] The existing Chinese utility model patent with publication number CN216132997U discloses a gas chromatograph with a protective structure, including a protective housing with a limiting groove on the inner side of the protective housing and a limiting slider installed inside the limiting groove; a support block installed above the limiting slider, with a support block sliding surface on the left side of the outer surface of the support block; and a gas chromatograph body support plate disposed on the left side of the support block sliding surface, with support plate sliding surfaces on both sides of the gas chromatograph body support plate. Compared with the prior art, this utility model provides a gas chromatograph with a protective structure, which has the following beneficial effects: the protective housing and the sliding support block are provided on the outer side of the gas chromatograph body, so that the protective housing can block most of the collision damage to the gas chromatograph body, playing a protective role, avoiding damage to the gas chromatograph body from collisions or affecting its detection accuracy, and extending the service life of the gas chromatograph body.

[0004] When a gas chromatograph is started, it shakes, which can cause uneven distribution of the sample in the column, affecting the separation effect and thus the accuracy of the detection results. In addition, most existing gas chromatographs are made of plastic, which is thin and has low strength. They may deform when subjected to impact, and cannot provide good protection for the internal components. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a gas chromatograph with a protective shell mechanism, which has the advantages of reducing the impact of shaking on the detection results and protecting the shell, thus solving the above-mentioned technical problems.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a gas chromatograph with a protective outer shell, comprising: a limiting frame, a limiting block fixedly installed on the left side of the limiting frame, a limiting column fixedly installed below the limiting block, a movable frame inserted through the rear side of the limiting column, a limiting plate fixedly installed inside the limiting frame, a silicone block fitted above the limiting plate, a base fixedly installed inside the movable frame, a connecting shaft fixedly installed inside the base, a movable block inserted through the center of the connecting shaft, a damping rod fixedly installed above the movable block, a spring inserted through the outer side of the damping rod, a connecting frame fixedly installed at the upper end of the damping rod, a movable shaft inserted through the connecting frame, a connecting block fixedly installed behind the movable shaft, and a gas chromatograph body fixedly installed behind the connecting block; the limiting column can restrict the movement direction of the movable frame.

[0009] As a preferred embodiment of this utility model, the limiting block is symmetrically installed at the upper and lower ends of the front and rear sides of the limiting frame with the center of the limiting frame as the reference. The limiting post is symmetrically installed on the left and right sides of the limiting block with the center of the limiting block as the reference. The limiting post connects the limiting blocks on the upper and lower sides of the limiting frame. The limiting block can fix the position of the limiting post.

[0010] As a preferred technical solution of this utility model, the front and rear sides of the limiting frame are provided with opening structures, the front and rear ends of the movable frame are fitted with the opening structures of the limiting frame, and the movable frame and the limiting posts on the front and rear sides of the limiting frame form a sliding connection; the movable frame can protect the gas chromatograph body.

[0011] As a preferred technical solution of this utility model, the limiting plate is installed symmetrically on the top and bottom surfaces of the inner wall of the limiting frame with the center of the limiting frame as the reference. The silicone blocks are installed equidistantly above the limiting plate, and the silicone blocks and the limiting plate form a fixed connection. The silicone blocks are in contact with the movable frame. The limiting plate facilitates the equidistant installation of the silicone blocks.

[0012] As a preferred embodiment of this utility model, the base is installed symmetrically on the front and rear sides of the inner wall of the movable frame with the center of the movable frame as the reference. The connecting shaft is installed symmetrically inside the base with the center of the base as the reference. The movable block is rotatably connected to the base through the connecting shaft. The connecting shaft facilitates the rotation of the movable block.

[0013] As a preferred embodiment of this utility model, the upper end of the spring is fixedly connected to the connecting frame, and the lower end of the spring is fixedly connected to the movable block; the spring facilitates the restoration of the damping rod.

[0014] As a preferred technical solution of this utility model, the connecting frame is rotatably connected to the connecting block through a movable shaft. The connecting block is symmetrically installed at the upper and lower ends of the front and rear sides of the gas chromatograph body. The connecting block can restrict the position of the gas chromatograph body.

[0015] Compared with the prior art, the present invention provides a gas chromatograph with a protective outer shell, which has the following advantages:

[0016] 1. This utility model utilizes silicone blocks, which are equidistantly installed above the limiting plate, forming a fixed connection between the silicone blocks and the limiting plate. Simultaneously, the limiting plate is mirror-symmetrically installed on the top and bottom surfaces of the inner wall of the limiting frame, with the center of the limiting frame as the reference. The silicone blocks contact the movable frame. Due to the deformation capability of silicone, the silicone blocks can deform upon impact to absorb some of the impact force. Meanwhile, the gas chromatograph body is movably installed inside the movable frame via a connecting block, connected by a damping rod. A portion of the impact force is absorbed by the damping rod, causing it to contract and rotate at a certain angle. This method prevents the impact force from being directly transmitted to the gas chromatograph body, thus providing protection for the gas chromatograph body.

[0017] 2. This utility model utilizes a damping rod whose upper end is connected to the gas chromatograph body via a connecting frame, movable shaft, and connecting block, forming a rotational connection. The lower end of the damping rod is connected to the base via the movable block and connecting shaft. Vibrations generated during the operation of the gas chromatograph body cause the damping rod to contract. Since the upper end of the spring is fixedly connected to the connecting frame and the lower end of the spring is fixedly connected to the movable block, the spring is squeezed by the connecting frame and movable block after the damping rod contracts. The spring's elastic force during contraction causes the damping rod to return to its original position. This method can absorb the vibration generated during the operation of the gas chromatograph body through the damping rod, thereby reducing the impact of vibration on the detection results.

[0028] The front and rear sides of the limiting frame 1 are provided with opening structures. The front and rear ends of the movable frame 13 are fitted with the opening structures of the limiting frame 1, and the movable frame 13 and the limiting posts 12 on the front and rear sides of the limiting frame 1 form a sliding connection.

[0029] The limiting plate 14 is installed symmetrically on the top and bottom surfaces of the inner wall of the limiting frame 1 with the center of the limiting frame 1 as the reference. The silicone block 15 is installed equidistantly above the limiting plate 14, and the silicone block 15 and the limiting plate 14 form a fixed connection. The silicone block 15 is in contact with the movable frame 13.

[0030] The base 16 is mirror-symmetrically installed on the front and rear sides of the inner wall of the movable frame 13 with the center of the movable frame 13 as the reference. The connecting shaft 17 is symmetrically installed inside the base 16 with the center of the base 16 as the reference. The movable block 18 is rotatably connected to the base 16 through the connecting shaft 17.

[0031] The upper end of the spring 110 is fixedly connected to the connecting frame 111, and the lower end of the spring 110 is fixedly connected to the movable block 18.

[0032] The connecting frame 111 is rotatably connected to the connecting block 113 via the movable shaft 112. The connecting block 113 is symmetrically installed at the upper and lower ends of the front and rear sides of the gas chromatograph body 114.

[0033] Specifically, the limiting frame 1 can limit the position of the limiting block 11, the limiting block 11 can fix the position of the limiting post 12, the limiting post 12 can limit the movement direction of the movable frame 13, the movable frame 13 can protect the gas chromatograph body 114, the limiting plate 14 can facilitate the equidistant installation of the silicone blocks 15, the silicone blocks 15 can protect the gas chromatograph body 114, the base 16 can facilitate the rotational connection between the movable block 18 and the movable frame 13, the connecting shaft 17 can facilitate the rotation of the movable block 18, the movable block 18 can facilitate the rotation of the damping rod 19, the damping rod 19 can absorb the force generated by vibration, the spring 110 can facilitate the restoration of the damping rod 19, the connecting frame 111 can facilitate the upper end of the damping rod 19 to be rotated with the connecting block 113 through the movable shaft 112, the movable shaft 112 can facilitate the rotation of the connecting frame 111, and the connecting block 113 can limit the position of the gas chromatograph body 114.

[0034] In use, the silicone blocks 15 are equidistantly installed above the limiting plate 14, forming a fixed connection between them. The limiting plate 14 is mirror-symmetrically installed on the top and bottom surfaces of the inner wall of the limiting frame 1, with the center of the limiting frame 1 as the reference. The silicone blocks 15 contact the movable frame 13. Due to the deformability of the silicone material, the silicone blocks 15 can deform upon impact to absorb some of the force. Simultaneously, the gas chromatograph body 114 is movably installed inside the movable frame 13 via the connecting block 113, connected by a damping rod 19. A portion of the impact force is absorbed by the damping rod 19, causing it to contract and rotate at a certain angle. This method prevents the impact force from being directly transmitted to the gas chromatograph body 114, facilitating the operation of the gas chromatograph body. 114 provides protection. The upper end of the damping rod 19 is connected to the gas chromatograph body 114 via the connecting frame 111, the movable shaft 112, and the connecting block 113, forming a rotational connection. The lower end of the damping rod 19 is connected to the base 16 via the movable block 18 and the connecting shaft 17. Vibrations generated during the operation of the gas chromatograph body 114 will cause the damping rod 19 to contract. Since the upper end of the spring 110 is fixedly connected to the connecting frame 111 and the lower end of the spring 110 is fixedly connected to the movable block 18, the spring 110 will be squeezed by the connecting frame 111 and the movable block 18 after the damping rod 19 contracts. The spring force of the spring 110 during contraction will restore the damping rod 19. This method can absorb the vibration generated during the operation of the gas chromatograph body 114 through the damping rod 19, thereby reducing the impact of vibration on the detection results.

[0035] In use, the silicone blocks 15 are equidistantly installed above the limiting plate 14, forming a fixed connection between them. The limiting plate 14 is mirror-symmetrically installed on the top and bottom surfaces of the inner wall of the limiting frame 1, with the center of the limiting frame 1 as the reference. The silicone blocks 15 contact the movable frame 13. Due to the deformability of the silicone material, the silicone blocks 15 can deform upon impact to absorb some of the force. Simultaneously, the gas chromatograph body 114 is movably installed inside the movable frame 13 via the connecting block 113, connected by a damping rod 19. A portion of the impact force is absorbed by the damping rod 19, causing it to contract and rotate at a certain angle. This method prevents the impact force from being directly transmitted to the gas chromatograph body 114, facilitating the operation of the gas chromatograph body. 114 provides protection. The upper end of the damping rod 19 is connected to the gas chromatograph body 114 via the connecting frame 111, the movable shaft 112, and the connecting block 113, forming a rotational connection. The lower end of the damping rod 19 is connected to the base 16 via the movable block 18 and the connecting shaft 17. Vibrations generated during the operation of the gas chromatograph body 114 will cause the damping rod 19 to contract. Since the upper end of the spring 110 is fixedly connected to the connecting frame 111 and the lower end of the spring 110 is fixedly connected to the movable block 18, the spring 110 will be squeezed by the connecting frame 111 and the movable block 18 after the damping rod 19 contracts. The spring force of the spring 110 during contraction will restore the damping rod 19. This method can absorb the vibration generated during the operation of the gas chromatograph body 114 through the damping rod 19, thereby reducing the impact of vibration on the detection results.
