[0035] After the test tube cap 2 is fixed, a support body 13 is provided on one side of the hinged position of the test tube cap body 21 inside the test tube cap to support the inside of the cap body. When the test tube cap 2 moves up and down, the test tube cap body 21 is hingedly opened and closed through the support of the support body 13; preferably, the upper edge of the support body 13 is flush with the upper edge of the test tube opening.

[0036] Optionally, the support body 13 is L-shaped, and its lower part is integrally or connected to the test tube wall; or, the vertical part of the support body 13 is a cylinder, which is integrally or adhesively provided on the outer side of the test tube wall.

[0037] Preferably, the silica gel sealing body 213 inside the test tube cap body 21 further includes a circular outer ring 2131 and a circular inner ring 2132. When the cap is closed, the circular outer ring 2131 and the circular inner ring 2132 fit / squeeze to surround the test tube opening ring to achieve sealing.

[0038] It should be noted that the circular outer ring 2131, the circular inner ring 2132, and the opening end 11 of the test tube are all circular rings, and the circular outer ring 2131 and the circular inner ring 2132 fit to squeeze the circular opening end of the test tube body 1 by different sizes.

The heights of the circular outer ring 2131 and the circular inner ring 2132 protruding relative to the circular base 2133 are different. For example, the height of the circular outer ring 2131 is greater to achieve a better squeezing and locking effect from the circular opening end of the test tube body 1.

[0040] The vacant part of the upper part of the support body 13 that is independent of the test tube wall allows the circular outer ring 2131 and the circular inner ring 2132 to fit into it without being squeezed.

[0041] Preferably, the hinge structure between the test tube lid body 21 and the cylindrical part 22 of the test tube lid 2 is provided with an independent first cross bar 211 in the inner space of the cylindrical part 22, so that there is a vacant part between the first cross bar 211 and the edge of the cylindrical part 22. At the same time, by the first cross bar 211 being located inside the accommodation through groove 222, the cylindrical part 22 of the test tube lid 2 is in a closed state at the height where the first cross bar 211 is located. Further, by the test tube lid body 21 being provided with an open cylinder 212 on one side of the first cross bar 211 and being snapped onto the cross bar for opening and closing, the test tube lid body 21 is hingedly connected around the cross bar. The first cross bar 211 and the cylindrical part 22 are tightened and fixed by exposing both ends after passing through the cylindrical part 22. The tightening method can be achieved by squeezing and sleeving silicone fixing caps at both ends. This is prior art and will not be elaborated here.

[0042] Preferably, the silica gel sealing body 213 inside the test tube lid body 21 is adhesively bonded to a plastic support part 214 on its outer side, and the plastic support part 214 extends a plastic protruding part 215 outward at the end opposite to the hinge of the test tube lid body 21.

[0043] Preferably, a fixing structure 12 with a vacant part is provided below the side of the test tube opening end 11 opposite to the support body 13. After the test tube lid 2 is fixed, a deformable and smooth fixing part 216 protruding inward from the plastic protruding part 215 extending from the test tube lid body 21 is provided. The deformable and smooth fixing part 216 can be snapped into and fixed in the fixing structure 12. When the test tube lid 2 is moved upward until the test tube lid body 21 is placed above the test tube opening end 11 and sealed by the silica gel sealing body 213, the protruding part extends downward and is sleeved in the fixing structure 12 of the lower part of the test tube opening end 11. When the test tube lid 2 is moved downward, the deformable and smooth fixing part 216 is lifted, and the test tube lid body 21 is lifted upward by the support body 13.

[0044] Preferably, the fixing structure 12 includes two protruding second cross bars 121 and an arc-shaped bar 122 having the same shape as the test tube between the two second cross bars 121. The two second cross bars 121 and the arc-shaped bar 122 are integrally formed rod frames and are integrally formed with the test tube wall at their respective positions.

[0045] A socket groove 223 with a lower end opening is provided at the cylindrical part 22 of the test tube cap 2 opposite to the rod frame. The lower end of the socket groove 223 is sleeved into the rod frame and its upper end is in a connected shape, realizing the limitation of the movement track of the test tube cap 2. Preferably, by arranging the fixing structure 12 below the edge of the test tube opening, when the test tube cap 2 moves downward and the cover body 21 of the test tube cap is lifted to a vertical or nearly vertical state, the connected part at the upper end of the socket groove 223 abuts against the rod frame position.

[0046] Preferably, the smooth fixing part is a soft silica gel body, which is squeezed into and out of the vacant part of the fixing structure 12 in a fitting manner.

An accommodation through groove 222 is provided at the contact part of the cylindrical part 22 and the inner silica gel extrusion body 221 with the vertical area of the support body 13 to penetrate the support body 13.

[0048] Preferably, the upper and lower parts of the support body 13 have different widths. When the test tube cap 2 moves downward, the width of the lower part of the support body 13 gradually increases, realizing the extrusion and fixing effect of the inner silica gel extrusion body 221 on the support body 13 and achieving relative fixation of the position between the test tube cap 2 and the test tube. Further, when the test tube cap 2 moves downward, the cover body 21 of the test tube cap rotates upward around the hinge position through the support body 13 to open the test tube.

[0049] The working principle of a multi-morphology bacteria-proof test tube of the present utility model is as follows:

[0050] The test tube includes a test tube body 1, a support body 13 integrated with or connected to the test tube body 1, and a fixing structure 12 with a vacant part on the side opposite to the support body 13 and integrated with or connected to the test tube body 1. The whole is used as a test tube body 1 without a cap when not connected to the test tube cap 2;

[0051] It further includes a test tube cap 2 detachably connected to the opening end 11 of the test tube. The opening cylinder 212 of the cover body 21 of the test tube cap is hinged and inserted into the first cross bar 211 to complete its connection and installation with the cylindrical part 22 of the test tube cap 2. After the cylindrical part 22 of the test tube cap 2 is clamped into the support body 13 through the accommodation through groove 222, it is connected and installed with the test tube body 1. The test tube cap 2 can move up and down outside the test tube wall.

[0052] When the test tube cap 2 moves downward, the cap body 21 of the test tube cap rotates upward and is hinged under the support of the support body 13 to open the test tube. The silica gel extrusion body 221 in the accommodation through groove 222 is extruded and clamped on the support body 13, and the upward opening state of the test tube cap body 21 is maintained through extrusion, so as to open the test tube opening to operate the solid and liquid in the test tube.

[0053] During the process of the test tube cap 2 moving upward and / or the cap body 21 of the test tube cap being pressed downward, the silica gel sealing body 213 inside the cap body 21 of the test tube cap fits and presses against the edge of the opening end 11 of the test tube to seal the test tube opening and achieve the sealing of the test tube, and the deformable smooth fixing part 216 is snapped into and fixed in the fixing structure 12 to maintain the sealed state of the test tube.

[0054] Furthermore, during the above operation process, there is no phenomenon that the operator touches the part of the test tube body 1 that may come into contact with the solid and liquid in the test tube, which greatly ensures the cleanliness of the solid and liquid in the test tube body 1 and prevents them from being contaminated by bacteria, achieving the antibacterial effect.

[0055] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
