Description

Technical Field

[0001] This utility model relates to the field of vacuum parallel concentrator technology, and in particular, to a concentrator cup compatible ring structure for a vacuum parallel concentrator. Background Technology

[0002] A vacuum parallel concentrator is a laboratory device based on the principle of vacuum decompression. By reducing ambient pressure, it lowers the boiling point of the solvent. Combined with heating and shaking functions, it enables rapid, parallel concentration or drying of multiple samples. It is widely used in pretreatment processes for environmental monitoring, food safety, and biochemical analysis, efficiently evaporating solvents and condensing them for recovery, avoiding damage to the target analytes from high temperatures.

[0003] Sample racks are typically used to support concentration cups, allowing them to be immersed in hot water. For example, the rack may have several placement holes into which the concentration cups can be directly inserted to maintain their upright position. However, when using irregularly shaped concentration cups (such as heart-shaped flasks) for solution concentration, the lack of stable support at the body and bottom can easily lead to tilting, rendering them unusable for concentration. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a compatible ring structure for a vacuum parallel concentrator's concentrator cup.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A concentrator cup compatibility ring structure for a vacuum parallel concentrator includes a connecting ring sleeved on the outside of the concentrator cup. The connecting ring includes a first abutting surface and a second abutting surface facing each other. The first abutting surface is used to support the outer wall flange of the concentrator cup, and the second abutting surface is used to engage the placement hole of the sample holder, so that the connecting ring is supported on the sample holder. The connecting ring is formed by splicing at least two connecting units, and a plurality of the connecting units are spliced ​​together by connectors.

[0007] Preferably, the outer wall of the connecting ring is provided with a connecting ring groove, and the connecting member includes a connecting ring sleeved in the connecting ring groove.

[0008] Preferably, the bottom of the inner wall of the connecting ring is formed with a flared opening, which gradually widens from top to bottom.

[0009] Preferably, the inner wall of the connecting ring is provided with an inwardly tapered clamping portion, which abuts against the outer wall of the concentration cup.

[0010] Preferably, the bottom of the inner wall of the connecting ring is provided with a receiving portion, which is used to engage with the outer wall protrusion of the concentration cup.

[0011] Preferably, the connecting ring is an O-ring.

[0012] Preferably, a gripping ring is provided on the outer wall of the connecting ring.

[0013] Preferably, the gripping ring is formed by assembling gripping blocks constructed on the outer wall of the connecting unit.

[0014] Preferably, the gripping ring and the connecting ring are separate, and fasteners are adapted between the gripping ring and the connecting ring.

[0015] Preferably, the top of the outer wall of the connecting ring is provided with an abutment ring groove, and the fastener includes a screw that passes through the gripping ring and extends into the abutment ring groove.

[0016] The beneficial effects of this invention are as follows: Two connecting units are sleeved onto the outside of the concentration cup and joined together to form a connecting ring. At this point, the outer flange of the concentration cup can be supported by the first contact surface of the connecting ring, allowing the concentration cup to be placed within the connecting ring. Subsequently, the connecting ring can be inserted into the placement hole of the sample holder. The second contact surface of the connecting ring allows it to be placed on the sample holder, ultimately achieving a stable position between the concentration cup and the sample holder. Compared with existing technologies, this invention allows for faster and more convenient installation onto the outer wall of the concentration cup and provides a more stable connection between the concentration cup and the sample holder, reducing the likelihood of the concentration cup tilting.

Detailed Implementation

[0022] 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.

[0023] like Figures 1 to 4 As shown, a concentrator cup compatible ring structure for a vacuum parallel concentrator includes a connecting ring 1 formed by assembling at least two connecting units 4. Figure 1 A preferred example is shown where there are two connecting units 4. As can be seen from the figure, the two connecting units 4 are joined together to form a connecting ring 1, and the two are also kept in a stable joined state by a connector 5.

[0024] The two ends of the connecting ring 1 are respectively provided with a first abutting surface 2 and a second abutting surface 3. When the connecting unit 4 is sleeved on the outside of the concentration cup and assembled into the connecting ring 1, the first abutting surface 2 can be used to support the outer wall flange 14 of the concentration cup, so that the concentration cup can be supported in the connecting ring 1.

[0025] The connecting ring 1 can be engaged in the placement hole of the sample holder 19 through the second abutment surface 3, which allows the connecting ring 1 and the concentration cup to be stably supported in the placement hole.

[0026] For example, the concentration cup can be a heart-shaped cup, which includes a heart-shaped body 15 and a mouth 16 from bottom to top, with a flange 14 provided on the outer wall of the mouth 16. The mouth 16 of the heart-shaped cup is stably supported on the top of the sample holder 19 by the connecting ring 1, while the body 15 of the heart-shaped cup is immersed in hot water to facilitate concentration.

[0027] The inner wall of the connecting ring 1 is constructed from bottom to top as a flared opening 8, a receiving portion 10, and a connecting portion 17. The connecting portion 17 is used to fit onto the outside of the bottle opening 16, and a clamping portion 9 is provided on the inner wall of the connecting portion 17. The clamping portion 9 is adapted to be tapered inward so as to abut against the bottle opening 16 to exert a clamping force on the condenser cup. The receiving portion 10 can engage with the protrusion 18 provided on the outer wall of the bottle opening 16. The flared opening 8 is specifically adapted to gradually expand from top to bottom so as to engage with the top of the bottle body 15.

[0028] For example, the connecting ring 1 is made entirely of an elastic material. In other configurations, the inner wall of the connecting ring 1 may not adopt the above-described structure and design; for example, it can be joined to the outer wall of the condenser cup by the adaptive use of an elastic material.

[0029] In some embodiments, a groove for the connecting ring 1 is formed on the outer wall of the connecting ring 1, and the connecting member 5 includes a connecting ring 7 disposed in the groove for the connecting ring 1, for example, the connecting ring 7 can be an O-ring. After the connecting unit 4 completes the splicing opening on the outside of the bottle mouth 16, the connecting ring 7 can be fitted onto the outside of the connecting ring 1 from top to bottom until the connecting ring 7 is engaged in the groove for the connecting ring 1. The connecting ring 7 can exert a binding force on the two connecting units 4, thereby ensuring the reliability of the shape of the connecting ring 1.

[0030] The assembly of adjacent connecting units 4 can also be achieved by bolt fastening or other methods, but the connection method of the connecting ring 7 is more convenient, so it is shown in the form of the preferred embodiment of this utility model.

[0031] In some embodiments, a gripping ring 11 is also provided on the outer wall of the connecting ring 1, allowing the operator to more easily lift the connecting ring 1 and the concentration cup inside it. For example, the gripping ring 11 can be formed by assembling gripping blocks (not shown) constructed on the outer wall of the connecting unit 4. In other configurations, the gripping ring 11 can also be separately disposed from the connecting ring 1, and the two can be connected by fasteners 12.

[0032] For example, the top outer wall of the connecting ring 1 may be constructed with an abutment groove 13, and the fastener 12 includes a screw that passes through the holding ring 11 and extends into the groove of the connecting ring 1. In a preferred example, the holding ring 11 and the connecting ring 7 are located at the upper and lower ends of the connecting ring 1, respectively. In this case, the holding ring 11 also serves to restrain the connecting ring 1, making the spliced ​​state of the connecting ring 1 more stable and reliable.

[0033] 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.
