Detailed Description

To facilitate an understanding of the utility model, the utility model is described more fully below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete.

Referring to fig. 1 to 4, in this embodiment, a centrifuge tube with two fastening positions includes a tube body 1 and a tube cap 2, the tube body 1 is connected to the tube cap 2 through a flexible connecting bridge 3, wherein the tube body 1, the tube cap 2 and the flexible connecting bridge 3 are integrally formed, and the tube cap 2 can be opened and closed in a direction relative to the tube body 1 by utilizing flexibility of the flexible connecting bridge 3.

In this embodiment, the tube body 1 has a nozzle 11 with an upper opening, and the tube body 1 is formed with a flange 12 extending toward the periphery of the nozzle 11, wherein the flange 12 is annularly arranged on the periphery of the nozzle 11. The bottom surface of the tube cap 2 is formed with a tube plug 21 which is matched with the tube opening 11 of the tube body 1 in an embedded manner, wherein the tube plug 21 of the embodiment is of a columnar structure, and the diameter width of the tube plug can be equal to or slightly larger than that of the tube opening 11. Secondly, the outer wall of the pipe plug 21 is formed with an annular sealing part 211 which is in contact fit with the inner wall of the pipe orifice 11, and the annular sealing part 211 is in contact fit with the inner wall of the pipe orifice 11, so that the sealing effect between the pipe plug 21 and the pipe orifice 11 is improved. In addition, the nozzle 11 is in a horn shape with a wide top and a narrow bottom, so that the pipe plug 21 can be more conveniently embedded in the nozzle 11.

In the present embodiment, the fixing buckles 22 are symmetrically formed on the left and right sides of the tube cover 2, wherein the fixing buckles 22 of the present embodiment are convexly formed on the left and right sides of the bottom surface of the tube cover 2, and the end of each fixing buckle 22 is formed with a hook 221. Secondly, the two fixing fasteners 22 are used for being fastened and matched with two sides of the protruding edge 12, specifically, when the tube cap 2 is closed with the tube body 1, the tube cap 2 is sealed and closed with the tube body 1 by using the two fixing fasteners 22 to be fastened and matched with two sides of the protruding edge 12 and the tube plug 21 to be embedded into the tube opening 11, and the hook portion 221 is fastened and matched with the bottom surface of the protruding edge 12, so that the hook portion cannot be easily disengaged.
