In order to make the technical problems, technical schemes and beneficial effects to be solved by the present application more clear, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

A sample swab tube provided by embodiments of the present application will now be described.

Please refer to fig. 1, 2 and 3, which are schematic structural diagrams of a sampling swab tube. The sampling swab tube comprises a tube body 1 and a cap 2, wherein the cap 2 comprises a cap main body 3 and a plug body 4 for being plugged into the tube body 1; the outer diameter of the cap main body 3 is larger than the outer diameter of the plug body 4, a first circumferential outer convex ring 5 and a second circumferential outer convex ring 6 which are distributed up and down are arranged on the outer surface of the plug body 4, and a circumferential inner convex ring 7 which is used for being clamped above the second circumferential outer convex ring 6 is arranged on the inner side of the pipe body 1 to play a role in fixation and sealing. The first circumferential outer convex ring 5 is matched with the inner wall of the pipe body 1, and plays a role in auxiliary sealing.

When the device is opened, the cap 2 can be taken out for sampling only by holding the tube body 1 with one hand, holding the cap 2 with the thumb and the index finger, applying pushing force to the thumb, laterally snapping the cap 2, separating the second circumferential outward convex ring 6 of the plug body 4 of the cap 2 from the circumferential inward convex ring 7 of the tube body 1, and then inserting the cap 2 back into the tube body 1 after the sampling is completed, so that the device is convenient and quick to operate with one hand in the opening process. In addition, when the cap 2 is taken out, the other hand can be used for connecting the tube body 1, or the tube body 1 can be placed on the bracket all the time, so that the whole operation can be carried out by one hand. Because no axial force is required, the support does not need to have a clamping function, and only the support tube body 1 is required to be prevented from falling down.

In order to avoid the cap 2 from shaking in the tube 1, referring to fig. 3, in one embodiment, when the circumferential inner convex ring 7 is tightly attached to the second circumferential outer convex ring 6, the lower end surface of the cap main body 3 contacts with the upper end surface of the tube 1.

Referring to fig. 5, in one embodiment, to avoid multiple snapping, the opening of the tube body 1 is broken, and the lower edge of the second circumferential outer convex ring 6 is 1.6-1.65mm away from the bottom of the plug body 4.

In order to facilitate the disengagement and entry of the second circumferentially outer convex ring 6 into the circumferentially inner convex ring 7, in one embodiment the first circumferentially outer convex ring 5, the second circumferentially outer convex ring 6 and the circumferentially inner convex ring 7 are all circular arc shaped protrusions.

Further, the radial height of the circular arc-shaped protrusion (namely, the distance between the outer surface of the plug body and the highest point of the circular arc-shaped protrusion) is 0.05mm-0.07mm, and the radius R of the arc-shaped section of the circular arc-shaped protrusion is 0.5mm-0.7mm. In this range, the second circumferential outer convex ring 6 and the circumferential inner convex ring 7 cooperate, which not only can play a good fixing role, but also can be smoothly broken off, and effectively avoid the cracking of the opening of the pipe body 1.

Still further, in one embodiment, the outer diameter of the portion of the plug body 4 where the first circumferential outer convex ring 5 and the second circumferential outer convex ring 6 are not provided is 10-12mm, the total length of the plug body 4 is 7.4-7.8mm, and the lower edge of the first circumferential outer convex ring 5 is 3-3.2mm from the upper edge of the second circumferential outer convex ring 6.

In addition, the cap 2 has a function of clamping the collecting sliver, referring to fig. 3, 4 and 5, in one embodiment, a receiving cavity 8 for allowing the collecting sliver to pass through is provided in the plug body 4, a placement block 9 is provided in the cap body 3, and a placement cavity 10 corresponding to the receiving cavity 8 is provided in the placement block 9.

Three supporting bars 11 are uniformly distributed between the outer wall of the placement cavity 10 and the inner wall of the cap main body 3 in the circumferential direction, and the outer sides of the supporting bars 11 are equal in height with the cap main body 3, so that materials can be reduced, and the cap main body 3 can be reinforced.

In one embodiment, a conical transition section 12 for communicating the two is arranged between the accommodating cavity 8 and the placing cavity 10, the inner diameter of the conical transition section 12 gradually contracts from bottom to top, and the conical transition section 12 plays a guiding role, so that the cotton sliver can be conveniently inserted and collected.

The utility model only needs one hand to open the operation, and is convenient and quick. The outer surface of the plug body 4 of the cap 2 is provided with a first circumferential outer convex ring 5 and a second circumferential outer convex ring 6 which are distributed up and down, and the inner side of the pipe body 1 is provided with a circumferential inner convex ring 7. During assembly, the second circumferential outer convex ring 6 enters the lower part of the circumferential inner convex ring 7 to play a role in fixing and sealing, and the first circumferential outer convex ring 5 is matched with the inner wall of the pipe body 1 to play a role in auxiliary sealing. When the circumferential inner convex ring 7 is tightly attached to the second circumferential outer convex ring 6, the lower end surface of the cap main body 3 is contacted with the upper end surface of the pipe body 1, so that the combination is tight, and the shaking can be avoided. In addition, in order to avoid multiple breaking, the opening of the tube body 1 is cracked, and the lower edge of the second circumferential outward convex ring 6 is 1.6-1.65mm away from the bottom of the plug body 4.

When the tube body 1 is opened, the cap 2 is only required to be held by one hand, the cap 2 is held by the thumb and the index finger, the cap 2 is pulled sideways by applying pushing force, the second circumferential outward convex ring 6 of the plug body 4 of the cap 2 is separated from the circumferential inward convex ring 7 of the tube body 1, the cap 2 can be taken out for sampling, and after the sampling is completed, the cap 2 is inserted back into the tube body 1. In addition, when the cap 2 is taken out, the other hand can be used for connecting the tube body 1, or the tube body 1 can be placed on the bracket all the time, so that the whole operation can be carried out by one hand.

The above embodiments are only for illustrating the technical solution of the present application, and are not limiting thereof; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present application, and are intended to be included in the scope of the present application.
