Description

Technical Field

[0001] This utility model relates to the field of liquid storage bottle fixing, and more specifically, to a rapid fixing device for liquid storage bottles of liquid chromatographs. Background Technology

[0002] Liquid chromatographs are core instruments in the field of analytical chemistry used to separate and analyze high-boiling-point, non-volatile, and thermally unstable organic compounds. They mainly consist of a reservoir (liquid bottle), a high-pressure pump, an injector, a chromatographic column, a detector, and a data processing system. The reservoir is used to store the mobile phase solvent, providing a stable and clean liquid source for the entire chromatographic analysis process. Its reliability and stability directly affect the accuracy and repeatability of the analytical results.

[0003] In practical use, the storage bottle is usually placed above or to the side of the liquid chromatograph, and the mobile phase is delivered to the pump through the pumping line. Since the storage bottle is exposed, even slight touches or vibrations during instrument operation or daily laboratory work can cause it to tip over, leading to mobile phase leakage, experimental interruption, or even instrument damage. In view of this, we propose a quick-fixing device for the liquid chromatograph storage bottle. Utility Model Content

[0004] The purpose of this invention is to solve the problem that liquid storage bottles are prone to tipping over.

[0005] To achieve the above-mentioned objectives and improve the aforementioned problems, this utility model provides a rapid fixing device for a liquid chromatograph storage bottle, comprising a liquid chromatograph body, a storage base fixedly connected to the upper surface of the liquid chromatograph body, a groove formed on the upper surface of the storage base, a conical groove formed on the bottom wall of the groove, a placement groove formed on the bottom wall of the conical groove, a fixing platform fixedly connected to the bottom wall of the placement groove, a third spring fixedly connected to the upper surface of the fixing platform, a sink base fixedly connected to the upper end of the third spring, a clearance groove formed on the inner wall of the placement groove, a telescopic rod rotatably connected to the top wall of the clearance groove, a sleeve slidably fitted on the outer surface of the telescopic rod, a clamping block provided at the end of the sleeve, the telescopic rod and the sleeve being integrally inclined downwards, and a connecting component provided on the clamping block.

[0006] As a preferred technical solution of this application, the connecting assembly includes two connecting ears, which are fixedly connected to the outer surface of the clamping block. A rotating shaft is fixedly connected between the two connecting ears, and the sleeve is rotatably sleeved on the outer surface of the rotating shaft.

[0007] As a preferred technical solution of this application, a torsion spring is fixedly connected between the sleeve and the connecting ear, and a torsion spring is also fixedly connected between the telescopic rod and the inner wall of the relief groove.

[0008] As a preferred technical solution of this application, a first spring is fixedly connected between the sleeve and the telescopic rod, and a rotating seat is rotatably connected to the bottom wall of the groove.

[0009] As a preferred technical solution of this application, a knob is fixedly connected to the rotating seat, a crossbar is fixedly connected to the inner wall of the knob, and a displacement ring is provided inside the placement groove.

[0010] As a preferred technical solution of this application, a compression ring is fixedly connected to the upper surface of the displacement ring, the upper surface of the compression ring is set to be wavy, and the lower surface of the crossbar is in contact with the upper surface of the compression ring.

[0011] As a preferred technical solution of this application, a sliding rod is fixedly connected to the lower surface of the extrusion ring, and a telescopic groove is provided on the bottom wall of the conical groove, with the lower end of the sliding rod sliding through the interior of the telescopic groove.

[0012] As a preferred technical solution of this application, a second spring is fixedly connected to the bottom wall of the telescopic groove, and the upper end of the second spring is fixedly connected to the lower end of the sliding rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: 1. Through the cooperation of the liquid chromatograph body, storage base, groove, conical groove, placement groove, fixing platform, third spring, sink base, clearance groove, telescopic rod, sleeve, clamping block and other structures, the liquid storage bottle is automatically clamped and fixed when inserted into the placement groove. When the liquid storage bottle is pressed down, the bottle body pushes the clamping block to expand outward and move downward along the telescopic rod and sleeve. At the same time, the first spring is stretched and the torsion spring is compressed until the bottom of the bottle contacts the sink base and the third spring is compressed to complete the locking. This device can quickly fix the liquid storage bottle without additional operation, effectively prevent tipping, and is simple, stable and reliable to operate. 2. By coordinating the connecting ear, rotating shaft, torsion spring, first spring, rotating seat, knob, crossbar, displacement ring, squeezing ring, sliding rod, telescopic groove, and second spring, the liquid storage bottle can be quickly unlocked and automatically reset. Rotating the knob drives the crossbar to rotate, and the crossbar presses down on the wavy upper surface of the squeezing ring, pushing the displacement ring downward. The displacement ring actively pushes open the clamping block to unlock the liquid storage bottle. After rotating the knob again, the second spring pushes the sliding rod to reset the squeezing ring. At the same time, the torsion spring and the first spring return the clamping block to its original position. This unlocking method is simple and intuitive, and has an anti-accidental lifting and jamming function, improving the safety of use. Attached Figure Description

A connecting component is provided on the clamping block 12.

[0021] By coordinating the structures of the liquid chromatograph body 1, storage base 2, groove 3, conical groove 4, placement groove 5, fixing platform 6, third spring 7, sink base 8, clearance groove 9, telescopic rod 10, sleeve 11, and clamping block 12, the liquid storage bottle is automatically clamped and fixed when inserted into the placement groove 5. When the liquid storage bottle is pressed down, the bottle body pushes the clamping block 12 to expand outward and move downward along the telescopic rod 10 and sleeve 11. At the same time, the first spring 16 is stretched and the torsion spring 15 is compressed until the bottom of the bottle contacts the sink base 8 and the third spring 7 is compressed to complete the locking. This device can quickly fix the liquid storage bottle without additional operation, effectively prevent tipping, and is simple, stable and reliable to operate.

[0022] Example 2 The rapid fixation device for the liquid chromatograph storage bottle provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the connecting assembly includes two connecting ears 13 for connecting components. The connecting ears 13 are fixedly connected to the outer surface of the clamping block 12. A rotating shaft 14 is fixedly connected between the two connecting ears 13. A sleeve 11 is rotatably sleeved on the outer surface of the rotating shaft 14. A torsion spring 15 is fixedly connected between the sleeve 11 and the connecting ears 13 to maintain the angle of the clamping block 12 when no external force is applied. Similarly, a torsion spring 15 is fixedly connected between the telescopic rod 10 and the inner wall of the relief groove 9 to maintain the angle of the telescopic rod 10. A first spring 16 is fixedly connected between the sleeve 11 and the telescopic rod 10 to provide cushioning and alerting. A rotating seat 17 is rotatably connected to the bottom wall of the groove 3.

[0023] A knob 18 for manual operation is fixedly connected to the rotating base 17. A crossbar 19 is fixedly connected to the inner wall of the knob 18. A displacement ring 20 is provided inside the placement groove 5. A compression ring 21 is fixedly connected to the upper surface of the displacement ring 20. The upper surface of the compression ring 21 is wavy. The lower surface of the crossbar 19 contacts the upper surface of the compression ring 21. A sliding rod 22 is fixedly connected to the lower surface of the compression ring 21. A telescopic groove 23 is provided on the bottom wall of the conical groove 4. The lower end of the sliding rod 22 slides through into the interior of the telescopic groove 23. A second spring 24 is fixedly connected to the bottom wall of the telescopic groove 23. The upper end of the second spring 24 is fixedly connected to the lower end of the sliding rod 22.

[0024] By coordinating the connecting ear 13, rotating shaft 14, torsion spring 15, first spring 16, rotating seat 17, knob 18, crossbar 19, displacement ring 20, squeezing ring 21, sliding rod 22, telescopic groove 23, and second spring 24, the liquid storage bottle can be quickly unlocked and automatically reset. Rotating the knob 18 drives the crossbar 19 to rotate, and the crossbar 19 presses down on the wavy upper surface of the squeezing ring 21, pushing the displacement ring 20 downward. The displacement ring 20 actively pushes open the clamping block 12 to unlock the liquid storage bottle. After rotating the knob 18 again, the second spring 24 pushes the sliding rod 22 to reset the squeezing ring 21. At the same time, the torsion spring 15 and the first spring 16 return the clamping block 12 to its original position. This unlocking method is simple and intuitive, and has an anti-accidental lifting and jamming function, which improves the safety of use.

[0025] The usage process of the rapid fixing device for liquid chromatograph storage bottles provided by this utility model is as follows: When placing and securing the liquid storage bottle, simply align it with the placement groove 5, then press it downwards to allow it to enter the interior of the placement groove 5 and contact the clamping block 12. Continuing to move it downwards will cause the clamping block 12 to move downwards and expand outwards. As the clamping block 12 moves downwards, it stretches the first spring 16 and simultaneously compresses the two torsion springs 15. Continuing to press it will bring it into contact with the upper surface of the base 8 and compress the third spring 7, thus completing the locking process. When the liquid storage bottle moves upwards, it will simultaneously compress the first spring 16. At this point, the increased resistance serves as a reminder to the staff that the device is not unlocked. Continuing to pull the sleeve 11 and telescopic rod 10 upwards will cause them to retract to their limit and become completely jammed, preventing further pulling. To unlock, simply rotate the knob 18 to drive the horizontal bar 19 in a circular motion. This, in turn, uses the cooperation of the horizontal bar 19 and the compression ring 21 to push the displacement ring 20 downwards. After the displacement ring 20 moves downwards, it actively pushes the clamping block 12 to unfold, thus unlocking the device. At the same time, the movement of the compression ring 21 will also compress the second spring 24. After the knob 18 is rotated again, the elastic force of the second spring 24 can reset the compression ring 21.
