Description

Technical Field

[0001] The utility model relates to the technical field of test workbenches, in particular to a workbench for liquid chromatography instruments. Background Technique

[0002] Liquid chromatography instruments belong to analytical test devices. The mobile phase can be injected into the system through a liquid pump, and then the sample liquid is guided to flow from the injector into the mobile phase, and is loaded into the chromatographic column under the guidance of the mobile phase. The components are separated through multiple adsorption and desorption operations and sent to the detector for detection. Then, the concentration data is sent to the external recorder through a signal and displayed through a chromatogram.

[0003] However, the workbench carrying the chromatograph is often a flat table body. Since the liquid chromatography instrument consists of multiple devices, if they are directly stacked on the table, there is a lack of auxiliary reinforcement at the edges. When the table shakes, each instrument will also shake accordingly, and the outer casing exposed to the air will also be contaminated with dust, which is very inconvenient.

[0004] Now, a new workbench for liquid chromatography instruments is proposed to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a workbench for liquid chromatography instruments to solve the problem of lack of protection of the instruments proposed in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A workbench for liquid chromatography instruments, including a table body and a protective frame. A protective frame is fixed on the left side of the top of the table body, and grooves are provided at the front and rear of the lower part inside the protective frame. The two sides of the top of the groove are respectively movably connected with limit blocks. Horizontal chambers are respectively provided between the two sides at the front and rear of the top of the protective frame, and a winding rod is provided between the two sides in the horizontal chamber. Elastic shafts are respectively assembled between the two sides of the winding rod and the horizontal chamber. A transparent dust-proof cloth is wound around the outer side of the winding rod, and a pull rod is horizontally fixed below the transparent dust-proof cloth. Longitudinal chutes are respectively provided at the front and rear ends of the left and right sides of the inner wall of the protective frame. A water pool is fixed on the upper right of the table body, and a storage box is fixed on the lower right of the table body.

[0007] Preferably, a temperature-assisted box is placed on the table top at the upper left of the table body, a detector is lapped above the temperature-assisted box, an automatic injector is lapped above the detector, and an infusion pump group is lapped above the automatic injector.

[0008] Preferably, the pull rod can be embedded in the groove, and the limit block can rotate horizontally on both sides above the groove.

[0009] Preferably, a frame is fixed at the rear of the top of the pool, and a water inlet is fixed at the center of the top of the frame. A faucet is installed between the lower part of the water inlet and the frame, and a hose is connected to the top end of the faucet. A nozzle is fixed at the end of the hose. A sleeve is fixed at the front left of the frame. A card slot is fixed on the left side inside the pool, and a filter box is inserted and fixed in the card slot.

[0010] Preferably, guide pipes are respectively fixed on both sides of the bottom of the pool, and a ring is fixed at the bottom of the guide pipe. Slide bars are respectively fixed on both sides of the bottom of the ring. A circle of folding pipes is fixed at the top of the ring, and insertion cylinders are respectively fixed on both sides of the top of the folding pipe. A spring is fixed between the top of the insertion cylinder and the ring. Waste liquid buckets are respectively placed on both sides inside the storage box.

[0011] Preferably, the spring is nested outside the slide bar, and the slide bar can vertically lift along the inner wall of the insertion cylinder.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: The workbench of the liquid chromatography instrument not only provides protection for the liquid chromatography instrument, realizes separate cleaning and sample preparation, but also facilitates garbage cleaning.

[0013] (1) By fixing a protective frame on the left side of the top of the table body, the temperature assistance box, detector, automatic sampler and infusion pump group are arranged in sequence from bottom to top on the upper left of the surface of the table body. The outside of this liquid chromatography instrument is wrapped by the protective frame, and shielding structures are installed at both the front and rear ends of the protective frame. Just hold the pull rod and lift it up and down along the two side chutes, and the transparent dust-proof cloth can be drawn out from the winding rod connected to the elastic shaft. After the pull rod slides into the groove inside, rotate the limit blocks assembled on both sides to make the transparent dust-proof cloth stably cover the front and rear ends of the protective frame, which can not only prevent the instrument from falling but also prevent the outer shell from getting dusty.

[0014] (2) By fixing a pool on the upper right of the table body, the inside of the pool is divided into two chambers. The filter box is fixed by a card slot in the left chamber, while the right chamber has no shielding. Just connect the external pipeline to the water inlet, turn the faucet to pour clean water into the hose, and then remove the nozzle from the sleeve to clean the utensils containing sample liquid and auxiliary materials. Different liquids can be processed separately to avoid the generation of extra substances due to liquid mixing.

[0015] (3) By placing waste liquid buckets on both sides inside the storage box, the two groups of guide pipes at the bottom of the pool respectively pass through the table body and are connected to the waste liquid buckets at the bottom. At this time, the folding pipe unfolds and presses on the top of the waste liquid bucket. At this time, the spring is stretched, and the folding pipe connected to the insertion cylinder can be fixed on the waste liquid bucket along the slide bar to prevent the waste liquid from splashing elsewhere when it falls into the storage box through the guide pipe. When replacing the waste liquid bucket, lift up the folding pipe and other objects, separate the folding pipe from the waste liquid bucket, and then the bucket body can be taken out.
