Technical Field

[0001] The utility model relates to the technical field of liquid storage for liquid chromatographs, in particular to a liquid storage device for liquid chromatographs. Background Art

[0002] Existing liquid chromatographs are all provided with a liquid storage device, which generally includes a box body and a positioning frame, on which a positioning port is provided for storing a liquid storage bottle. However, the stability of the existing storage device is poor, and the liquid storage bottle may fall and break due to carelessness of the staff.

[0003] According to the description of a liquid storage device for a liquid chromatograph disclosed on the patent website (authorization announcement number: CN 219641646U), "The utility model relates to the technical field of liquid storage bottle storage, and discloses a liquid storage device for a liquid chromatograph, including a chromatograph body, a liquid storage mechanism is arranged on the top of the chromatograph body, and a supporting mechanism is arranged on the bottom of the chromatograph body. In the utility model, the liquid storage bottle is first fixed by the liquid storage mechanism, and liquid storage bottles of different sizes can be placed, and the impact force brought to the placement box by collision is reduced. The liquid storage bottle is placed in the placement slot. When the clamping plate touches the liquid storage bottle, the spring 2 is squeezed due to the force and the telescopic column 2 is contracted. After the placement, the spring 2 squeezes the clamping plate due to its own force to fix the liquid storage bottle. At the same time, because the spring 2 can be deformed, the clamping plate can clamp liquid storage bottles of different volumes, making the liquid storage mechanism more stable. When the device collides, the spring 1 and the telescopic column 1 can be contracted to reduce the impact force caused by the collision."

[0033] Embodiment 2:

[0034] See also Figure 4 In combination with the first embodiment, it is further obtained that the lifting component 31 includes a crossbeam 313, the crossbeam 313 is fixedly installed at the bottom inner side of the protective mechanism 2, a slider 318 is slidably installed inside the crossbeam 313, a connecting rod 317 is rotatably installed inside the top of the slider 318, a lifting plate 315 is rotatably installed at one end of the connecting rod 317 away from the slider 318, a spring shaft 312 is fixedly installed on the top of the lifting plate 315, a sponge pad 311 is fixedly installed on the top of the spring shaft 312, a multiple bidirectional threaded rod 316 is threadedly installed inside the slider 318, and a hexagonal rotating cap 314 is fixedly installed on the left end of the multiple bidirectional threaded rod 316, which can push the glass bottle to lift.

[0035] The lifting plate 315 is fixedly installed at the inner bottom of the protection mechanism 2, a T-shaped slot is provided inside the crossbeam 313, a slider 318 is slidably installed inside the T-shaped slot, and a multi-bidirectional threaded rod 316 is provided with opposing threads outside to limit the lifting of the glass bottle.

Two first spring rods 322 and two second spring rods 325 are provided to buffer the liquid storage glass bottle for the liquid chromatograph.

[0038] In actual operation, when the device is used, when it is necessary to store the storage liquid for the liquid chromatograph, the glass bottle is filled with the storage liquid for the liquid chromatograph, and then the glass bottle is placed on the inner side of the first curved plate 321, and the first curved plate 321 and the second curved plate 324 are in contact with the outside of the glass bottle, and then the glass bottle is slidably installed on the inner side of the first curved plate 321 and the second curved plate 324, and finally the bottom of the glass bottle is in contact with the sponge pad 311, and the storage of the storage liquid for the liquid chromatograph is completed.
