Description

Technical Field

[0001] This utility model relates to the field of mass spectrometry technology, and in particular to a liquid phase solution storage structure. Background Technology

[0002] A liquid chromatography-mass spectrometry (LC-MS) instrument is an analytical instrument that combines a liquid chromatograph (LC) with a mass spectrometer (MS). The sample solution is delivered into the chromatographic column by a high-pressure pump. Within the column, different compounds, due to varying interaction forces with the stationary and mobile phases, pass through the column at different speeds under the influence of the mobile phase, thus achieving separation. The separated components then sequentially enter the mass spectrometer detector, where they are ionized in the ion source into ions with different mass numbers and charges. These ions move in an electromagnetic field, and due to their different mass-to-charge ratios (m / z), their motion varies. The mass analyzer separates the ions according to their mass-to-charge ratios, resulting in a mass spectrum arranged in order of mass-to-charge ratio.

[0003] Existing technology, such as the patent with publication number CN220626282U, discloses a solution storage device for a liquid chromatography-mass spectrometer. By driving the bidirectional threaded screw to rotate, due to the interaction between the threads, nut one and nut two move in opposite directions on the slide rail. Therefore, nut one drives the bearing rod one and the arc-shaped clamp to approach the outer liner, and nut two drives the bearing rod two and the arc-shaped clamp to approach the outer liner. As nut one and nut two move in opposite directions, the arc-shaped clamp holds the outer liner on the main body of the mass spectrometer.

[0004] It uses a drive screw to move the clamping plate to clamp and fix the liquid storage bottle, which makes clamping and disassembly quite troublesome. Utility Model Content

When fixing the liquid storage bottle, it is only necessary to perform a simple operation of inserting the card holder and then inserting the card holder into the fixing seat. When it is necessary to remove the liquid storage bottle, it is only necessary to press down on the liquid bottle and then lift it to achieve separation. The clamping and disassembly process of the liquid storage bottle can be completed quickly and easily.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A liquid phase solution storage structure includes a mounting base disposed on the main body of a mass spectrometer and a retainer connected to the mounting base;

Detailed Implementation

[0029] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] See Figures 1-4 This utility model provides a technical solution:

[0031] Example:

[0032] like Figures 1-4As shown, a liquid phase solution storage structure includes a cylindrical mounting base 2 (open at one end and closed at the other end) and a cylindrical retainer 3 (open at one end and closed at the other end) connected to the mounting base 2, which is mounted on the main body 1 of a mass spectrometer.

[0033] The fixed base 2 has a U-shaped cross section, and the card holder 3 is detachably connected to the fixed base 2 via a quick-release assembly;

[0034] The card holder 3 is used to fix the liquid storage bottle 4.

[0035] like Figures 2-4 As shown, the quick-release assembly includes a limiting block 10, a first telescopic rod 13, a first spring 14 (wherein multiple sets of limiting blocks 10, first telescopic rods 13, and first springs 14 can be provided, and each set of limiting blocks 10, first telescopic rods 13, and first springs 14 is evenly distributed along the bottom circumference of the card seat 3), a second telescopic rod 16, a second spring 17, and a relief ring 8. The second telescopic rod 16 is vertically installed at the inner bottom of the fixed seat 2 to support the card seat 3. When the card seat 3 moves toward the bottom of the fixed seat 2, the second telescopic rod 16 retracts and compresses the second spring 17. The second spring 17 is sleeved on the outside of the second telescopic rod 16.

[0036] The first telescopic rod 13 is radially arranged on the outer bottom surface of the card seat 3, and the movable end of the first telescopic rod 13 is connected to the limiting block 10. The outer diameter of the card seat 3 is adapted to the inner diameter of the fixed seat 2.

[0037] The inner circumferential wall of the fixed base 2 is provided with a sliding groove 7, and the card seat 3 is engaged with the fixed base 2 through the sliding groove 7 and the limiting block 10; the relief ring 8 is slidably disposed in the sliding groove 7, and the relief ring 8 can move along the axial direction of the fixed base 2.

[0038] The retraction ring 8 is used to squeeze the first telescopic rod 13 to retract when the card seat 3 moves toward the bottom of the fixed seat 2, so that the limiting block 10 is located on the inner side of the outer circumferential wall of the card seat 3, and moves with the limiting block 10 to the top of the slide groove 7 when the card seat 3 moves in the opposite direction until the limiting block 10 contacts the inner circumferential wall of the fixed seat 2.

[0039] Furthermore, such as Figure 2 and Figure 3 As shown, the card holder 3 has an L-shaped mounting plate at its outer bottom. A mounting cavity is provided between the mounting plate and the outer bottom surface of the card holder 3. The first telescopic rod 13 is set in the mounting cavity, and the fixed end of the first telescopic rod 13 is connected to the vertical section of the mounting plate. The width of the mounting cavity is adapted to the width of the limiting block 10 and is used to guide the limiting block 10 to ensure that the displacement of the limiting block 10 is always linear.

[0040] The limiting block 10 is provided with a first inclined surface 9, which is used to guide the limiting block 10 when the card seat 3 enters the fixed seat 2.

[0041] The cross-section of the relief ring 8 is an isosceles trapezoid, and the side of the relief ring 8 away from the liquid storage bottle 4 is a second inclined surface 11.

[0042] A chamfer 12 is provided between the top surface of the slide groove 7 and the inner wall of the fixed base 2. The chamfer 12 allows the limiting block 10 to smoothly transition from the relief ring 8 to the inner wall of the fixed base 2.

[0043] The card holder 3 is equipped with an adsorption component, which is used to adsorb the liquid storage bottle 4 onto the card holder 3 by means of the pressure difference between the inside and outside of the card holder 3.

[0044] The adsorption assembly includes a sealing ring 5 and a blocking block 6. The sealing ring 5 is coaxially disposed on the inner wall of the card holder 3. The inner diameter of the sealing ring 5 is adapted to the outer diameter of the liquid storage bottle 4. The bottom of the card holder 3 is provided with a through hole for communicating with the interior of the card holder 3. The blocking block 6 is inserted into the through hole for opening or closing the through hole.

[0045] The end of the second telescopic rod 16 is provided with a lifting plate 15. The lifting plate 15 can increase the contact area with the card holder 3, thereby ensuring the stability of the card holder 3.

[0046] The first telescopic rod 13 and the second telescopic rod 16 have the same structure but different dimensions, and are both existing technologies. They can be, but are not limited to, combinations of sleeves and connecting rods. The connecting rod is slidably disposed within the sleeve as the movable end of the telescopic rod, and the sleeve serves as the fixed end connected to the mounting plate or fixed base 2. Their specific working principles will not be elaborated here.

[0047] Working principle: When it is necessary to fix the liquid storage bottle 4, first install the liquid storage bottle 4 onto the card holder 3. The sealing block 6, sealing ring 5 and card holder 3 cooperate with each other to form a suction cup, so that the liquid storage bottle 4 can be adsorbed onto the card holder 3. When it is necessary to separate the liquid storage bottle 4 from the card holder 3: remove the sealing block 6 from the card holder 3, so that the air pressure inside and outside the card holder 3 is the same, and release the adsorption and fixation of the liquid storage bottle 4.

[0048] After the liquid storage bottle 4 is fixed, the holder 3 is aligned with the fixed base 2, and the holder 3 is placed into the fixed base 2. During this process, the limiting block 10 retracts radially along the holder 3 under the action of the first inclined surface 9 (the first spring 14 is compressed and the first telescopic rod 13 retracts) until the end face of the limiting block 10 contacts the inner circumferential wall of the fixed base 2. As the holder 3 moves downward until the limiting block 10 is aligned with the slide groove 7, since there is no limiting force from the inner circumferential wall of the fixed base 2, the limiting block 10 resets under the action of the first spring 14 and extends into the slide groove 7. At this time, the upper surface of the limiting block 10 forms an axial limiting force with the top surface of the slide groove 7, thereby preventing the holder 3 from being pulled out. The liquid storage bottle 4 is fixed to the mass spectrometer body 1 through the holder 3 and the fixed base 2.

[0049] When it is necessary to remove the liquid storage bottle 4, press down on the liquid storage bottle 4. The liquid storage bottle 4 drives the card holder 3 to move downward. The card holder 3 drives the limiting block 10 to move synchronously. When the limiting block 10 contacts the relief ring 8, the limiting block 10 contracts radially under the squeezing action of the relief ring 8 and the first inclined surface 9 until the limiting block 10 contracts and passes over the relief ring 8.

[0050] At this point, the liquid storage bottle 4 is lifted, and the liquid storage bottle 4 drives the card holder 3 and the limiting block 10 to move accordingly. At the same time, under the friction of the limiting block 10 and the second inclined surface 11, the retraction ring 8 moves upward synchronously until the retraction ring 8 moves to contact the top surface of the slide groove 7. The axial limiting effect of the top surface of the slide groove 7 on the retraction ring 8 prevents the retraction ring 8 from continuing to move. At this time, the limiting block 10 continues to move along the second inclined surface 11 and retracts until it passes over the inside of the retraction ring 8 and enters the inner circumferential wall of the fixed seat 2. Then, by continuing to apply upward force, the card holder 3 and the fixed seat 2 can be separated.

[0051] After the card holder 3 is separated from the fixed seat 2, the sealing block 6 is removed to connect the inside of the card holder 3 with the outside. After the air pressure inside and outside the card holder 3 is the same, the liquid storage bottle 4 can be easily removed.

[0052] When fixing the liquid storage bottle, this utility model only requires a simple operation of inserting the card holder and then inserting the card holder into the fixing base. When it is necessary to remove the liquid storage bottle, it is only necessary to press down on the liquid dispensing bottle and then lift it to separate it. The clamping and disassembly process of the liquid storage bottle can be completed quickly and easily.

[0053] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
