Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, and in particular to a sampling device for quality testing of Chinese medicinal materials. Background Technology

[0002] Traditional Chinese medicine (TCM) herbs mainly come from natural medicines and their processed products, including plant oils, animal oils, mineral oils, and some chemical drugs and biological products. Common TCM herbs include wolfberry, rhubarb, poria cocos, plantain seed, hawthorn, licorice, yam, ginseng, atractylodes macrocephala, motherwort, black nightshade, and clematis chinensis. Some TCM herbs need to be pulverized, and samples need to be taken for testing after pulverization.

[0003] To ensure the efficacy of Chinese medicinal materials, it is necessary to sample and test them regularly. Currently, sampling is mostly done using double-layer powder sampling tubes, which consist of an outer tube and an inner tube that can rotate between each other. However, there is currently no control mechanism between the outer and inner tubes, which makes it difficult to control the angle when adjusting the inner and outer tubes, and can easily cause powder to spill out from the inlet. There is room for improvement. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sampling device for quality testing of Chinese medicinal materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sampling device for quality testing of traditional Chinese medicinal materials includes an insertion tube, a storage tube installed inside the insertion tube, a first channel formed on the outer wall of the insertion tube, a second channel formed on the outer wall of the storage tube that matches the first channel, a top sleeve fixed to the top of the storage tube, two guide grooves formed on the outer wall of the insertion tube, a lower fixing ring fitted on the outer wall of the insertion tube, a guide block that matches the guide grooves fixed inside the lower fixing ring, and a pressing mechanism for moving the lower fixing ring on the outer wall of the storage tube.

[0007] As a further embodiment of this utility model, an upper fixing ring is fixedly sleeved on the outer wall of the storage tube, and a spring is fixed between the lower fixing ring and the upper fixing ring, with the spring sleeved on the outer wall of the insertion tube.

[0008] As a further embodiment of this utility model, the pressing mechanism includes a fixed sleeve sleeved on the outer wall of the storage tube, two fixed ears fixed on the outer wall of the lower fixed ring, a positioning rod fixed on the top of the fixed ears, and the positioning rod fixedly passing through the hole on the fixed sleeve.

[0009] As a further embodiment of this utility model, the outer wall of the top sleeve is fixed with two brackets, and the brackets are provided with insertion holes for the positioning rod to pass through.

[0010] As a further embodiment of this utility model, two protective shells are fixed to the bottom of the upper fixing ring, the protective shells cover the spring, and the two protective shells are provided with a gap for the fixing ear to move.

[0011] As a further embodiment of this invention, a cone is fixed at the bottom of the insertion tube to facilitate the insertion of the medicinal powder.

[0012] As a further embodiment of this invention, the top of the storage tube is equipped with a plug to serve as a seal.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention utilizes a set of components including an insertion tube, a storage tube, a pressing mechanism, a lower fixing ring, a guide groove, and an upper fixing ring. When sampling is required, pinching the fixing sleeve and the support causes the fixing sleeve to move upward, and the guide block on the lower fixing ring slides in the guide groove, forcing the insertion tube to rotate until the first channel on the insertion tube and the second channel on the storage tube are in the same position. At this point, the insertion tube is inserted into the Chinese herbal medicine powder for sampling. Then, the fixing sleeve is released naturally, and the first and second channels are misaligned again to seal the powder. This effectively solves the problems raised in the background technology, enabling sampling and sealing by pressing. Sealing is achieved simply by releasing the pressing mechanism, making it safer and avoiding the scattering of medicinal powder caused by improper manual rotation. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Reference Figures 1-4 A sampling device for quality testing of Chinese medicinal materials includes an insertion tube 1, a storage tube 3 installed inside the insertion tube 1, a first channel 4 opened on the outer wall of the insertion tube 1, a second channel 5 adapted to the first channel 4 opened on the outer wall of the storage tube 3, a top sleeve 7 fixed on the top of the storage tube 3, two guide grooves 13 opened on the outer wall of the insertion tube 1, a lower fixing ring 10 sleeved on the outer wall of the insertion tube 1, a guide block adapted to the guide groove 13 fixed inside the lower fixing ring 10, and a pressing mechanism 6 for moving the lower fixing ring 10 on the outer wall of the storage tube 3.

[0023] In this embodiment, an upper fixing ring 11 is fixedly sleeved on the outer wall of the storage tube 3, and a spring 12 is fixed between the lower fixing ring 10 and the upper fixing ring 11. The spring 12 is sleeved on the outer wall of the insertion tube 1.

[0024] In this embodiment, the pressing mechanism 6 includes a fixed sleeve 16 sleeved on the outer wall of the storage tube 3, and two fixed ears 14 fixed on the outer wall of the lower fixed ring 10. A positioning rod 15 is fixed on the top of the fixed ears 14, and the positioning rod 15 is fixedly arranged through the hole on the fixed sleeve 16.

[0025] In this embodiment, two supports 8 are fixed to the outer wall of the top sleeve 7. Each support 8 has an insertion hole 17 for the positioning rod 15 to pass through. In the initial state, i.e., when the spring 12 is in its natural state, the first channel 4 on the insertion tube 1 is misaligned with the second channel 5 on the storage tube 3, and the insertion tube 1 and the storage tube 3 are not connected. When sampling is required, the fixed sleeve 16 and the supports 8 are pinched to move the fixed sleeve 16 upwards. The fixed sleeve 16, through the positioning rod 15, causes the lower fixing ring 10 to move upwards, compressing the spring 12 and lowering the lower fixing ring 10. The guide block slides in the guide groove 13, forcing the insertion tube 1 to rotate. It should be noted that the spring 12 itself has torque force and will not interfere with the rotation of the insertion tube 1 until the first channel 4 on the insertion tube 1 and the second channel 5 on the storage tube 3 are in the same position. At this time, the insertion tube 1 is inserted into the Chinese herbal medicine powder for sampling. Then the fixing sleeve 16 is released naturally, the spring 12 is extended, and the first channel 4 and the second channel 5 are misaligned again to block the powder, so that the sampled powder is stored in the storage tube 3. The powder can be poured out from the top of the storage tube 3.

[0026] In this embodiment, two protective shells 18 are fixed to the bottom of the upper fixing ring 11. The protective shells 18 cover the spring 12, and the two protective shells 18 are provided with a gap for the fixing ear 14 to move, which serves the purpose of protection and aesthetics.

[0027] In this embodiment, a cone 2 is fixed at the bottom of the insertion tube 1 to facilitate the insertion of the medicine powder into the insertion tube 1.

[0028] In this embodiment, the top of the storage tube 3 is equipped with a plug 9, which serves to seal the tube.

[0029] Working principle: The system includes an insertion tube 1, a storage tube 3, a pressing mechanism 6, a lower fixing ring 10, a guide groove 13, and an upper fixing ring 11. In the initial state, when the spring 12 is in its natural state, the first channel 4 on the insertion tube 1 and the second channel 5 on the storage tube 3 are misaligned, and the insertion tube 1 and the storage tube 3 are not connected. When sampling is required, the fixing sleeve 16 and the bracket 8 are pinched, causing the fixing sleeve 16 to move upward. The fixing sleeve 16 drives the lower fixing ring 10 to move upward via the positioning rod 15, compressing the spring 12. The guide block on the lower fixing ring 10 slides in the guide groove 13, forcing the insertion tube 1 to rotate. It should be noted that the spring... The spring 12 itself has a torque force and will not interfere with the rotation of the insertion tube 1 until the first channel 4 on the insertion tube 1 and the second channel 5 on the storage tube 3 are in the same position. At this time, the insertion tube 1 is inserted into the Chinese herbal medicine powder for sampling. Then the fixing sleeve 16 is released naturally, the spring 12 is stretched, and the first channel 4 and the second channel 5 are misaligned again to seal, so that the sampled medicine powder is stored in the storage tube 3. The medicine powder can be poured out from the top of the storage tube 3, which effectively solves the problem raised in the background technology. It can achieve sampling and sealing by pressing. The sealing can be done by simply releasing the pressing mechanism 6, which is safer and avoids the medicine powder from scattering due to improper manual rotation.

[0030] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.
