[0026] All terms used in this protocol have the same meaning as understood by one of ordinary skill in the art, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and not as idealized or highly formalized, unless explicitly defined herein.

[0027] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0028] refer to Figures 1-3As shown, this solution provides a weighing support tube assembly, which includes a connecting base 1 and a support tube 2. The first end of the support tube 2 is connected to the connecting base 1 and the second end allows a flexible tubular sample to enter. The connecting base 1 can be connected to an electronic balance and allows the support tube 2 to extend vertically so as to support the flexible tubular sample through the inner wall of the support tube 2.

[0029] The connecting base 1 can be connected to the electronic balance so that the weighing support tube assembly is stably held on the electronic balance.

[0030] One end of the support tube 2 is connected to the connecting base 1, and the other end forms an opening to allow the sample to be measured to enter, for example, to allow the flexible tubular sample to be measured to enter.

[0031] After the connecting base 1 is connected to the electronic balance, the support tube 2 remains vertically extended, with its second end located at the top, allowing the flexible tubular sample to enter by its own gravity. The flexible tubular sample can be supported on the inner wall of the support tube 2, and its overall shape remains roughly vertically extended. Of course, the flexible tubular sample does not extend in a straight line, but in a curve. It is only under the action of the support tube 2 that the overall shape remains roughly straight to avoid entanglement.

[0032] In this scheme, the support tube can provide stable support for the flexible tubular sample, prevent it from tangling, and achieve accurate measurement of the flexible tubular sample.

[0033] In some embodiments, the weighing support tube assembly further includes a limiting tube 3 disposed at the second end of the support tube 2. The limiting tube 3 includes a tapered section 31 and a straight section 32 connected in sequence. The tapered section 31 guides the flexible tubular sample into the tube, and the straight section 32 accommodates and supports the flexible tubular sample. The limiting tube 3 can be disposed within the support tube 2, including the tapered section 31 and the straight section 32. The inner diameter of the straight section 32 is smaller than the inner diameter of the support tube 2 but larger than the outer diameter of the flexible tubular sample. Therefore, the straight section 32 can support the flexible tubular sample, while the tapered section 31 can guide the flexible tubular sample into the straight section 32. (Reference) Figure 2 As shown, the inner diameter of the tapered tube 31 gradually decreases from top to bottom, and the inner diameter of the straight tube 32 is the same as the inner diameter of the lower end of the tapered tube 31.

[0034] In some embodiments, the limiting tube 3 is detachably disposed within the support tube 2 and clearance-fitted with the support tube 2. The tapered tube portion 31 and the straight tube portion 32 may have substantially the same outer diameter, and are clearance-fitted with the support tube 2. After the limiting tube 3 is inserted into the support tube 2, it will not move laterally under the restraining effect of the support tube 2. In addition, the limiting tube 3 may include a flange disposed at the upper end of the tapered tube portion 31 to hold the limiting tube 3 at the upper end of the support tube 2.

[0035] In some embodiments, a sealing plate is provided at the first end of the support tube 2. The lower end of the flexible tubular sample entering the support tube 2 can be supported on the sealing plate, and the upper end of the flexible tubular sample can remain outside the support tube 2, facilitating clamping by an operator using a clamping tool. The size of the support tube 2 can be determined according to the length of the flexible tubular sample, ensuring that the length of the support tube 2 is less than the length of the flexible tubular sample, so as to ensure that the upper end of the flexible tubular sample can remain outside the support tube 2. The support tube 2 can be a seamless tube to avoid the influence of seams on the flexible tubular sample.

[0036] In some embodiments, the connecting base 1 includes a positioning tube 11, the first end of which is capable of accommodating the insertion of the first end of the support tube 2. The positioning tube 11 can support and accommodate the support tube 2, and can restrict the lateral movement of the support tube 2.

[0037] In some hosts, the support tube 2 is detachably inserted into the positioning tube 11, and the support tube 2 and the positioning tube 11 are in a clearance fit. The detachable fit between the support tube 2 and the positioning tube 11 facilitates the replacement of support tubes 2 of different sizes to accommodate samples of different sizes. The outer diameter of the support tube 2 is substantially the same as the inner diameter of the positioning tube 11, and the clearance fit restricts the lateral movement of the support tube 2, improving stability.

[0038] In some embodiments, the support base includes a connecting rod 12 connected to the second end of the positioning tube 11. The connecting rod 12 has a threaded structure and can be screwed onto the electronic balance. The connecting rod 12 may form an external thread or a threaded hole, and it can be screwed onto the electronic balance to connect the weighing support tube assembly to the electronic balance. When connected to the electronic balance, the connecting rod 12 extends vertically, causing the positioning tube 11 and the support tube 2 to also extend vertically.

[0039] In some embodiments, the connecting base 1 further includes an adapter that can be detachably connected to the connecting rod 12. The adapter can be connected to the connecting rod 12; depending on the type of electronic balance, a corresponding adapter can be selected to connect the connecting rod 12 to the electronic balance. One end of the adapter can form a threaded structure (threaded hole or threaded rod) that mates with the connecting rod 12, while the other end can form other connecting structures, such as threaded rods of different outer diameters.

[0040] In some embodiments, the connecting base 1 includes a support plate 13 located between the second end of the positioning tube 11 and the connecting rod 12. The support plate 13 protrudes radially relative to the positioning tube 11 to support calibration weights. Calibration weights can be mounted on the support plate 13. Before weighing, the calibration weights can be measured to determine if the weighing support tube assembly is suitable. For example, if the difference between the measurement result and the actual weight of the calibration weight is too large, it indicates a problem with the weighing support tube assembly.

[0041] In some embodiments, the support plate 13 is circular, and the support plate 13, the connecting rod 12, and the positioning tube 11 are coaxially arranged. That is, the centers of gravity of the support plate 13, the connecting rod 12, and the positioning tube 11 are aligned. Furthermore, the support tube 2 is coaxial with the positioning tube 11, and the limiting tube 3 is coaxial with the support tube 2. This ensures that the center of gravity of the overall structure coincides with the central axis of the support tube 2, and the overall structure is free from eccentricity, thus avoiding affecting the measurement results.

[0042] The weighing support tube assembly is entirely made of metal.
