Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-2 This utility model provides a technical solution:

[0019] Example 1

[0020] The problems to be solved are as follows: the existing test tube sealing structure is inconvenient to open, requiring two hands to operate and making it difficult to open with one hand, and the sealing structure of the test tube is insufficient.

[0021] The solution is as follows: A plastic single-handed press-type cap-opening tube includes a device body 1, which comprises a test tube body 2, an elastic sealing cap 3, a spring hinge 4, a control button device 5, and a mounting cover 6. The mounting cover 6 has a cylindrical structure and is installed on the top of the test tube body 2. One end of the spring hinge 4 is welded to the mounting cover 6, and one end of the elastic sealing cap 3 is installed on the other end of the spring hinge 4. The mounting cover 6 has a mounting opening 7 on its side and a mounting groove 15 on its top. The mounting groove 15 and the mounting opening 7 are a through structure. The control button device 5 is installed inside the mounting opening 7. The control button device 5 has an L-shaped structure. The button device 5 includes a push button 8, a moving rod 9, a locking rod 10, a locking block 11, and a return spring 12. The moving rod 9 is installed on the right end of the push button 8. The locking rod 10, the moving rod 9, and the locking block 11 are smoothly transitioned and integrally formed. The locking rod 10 is located at the top right end of the moving rod 9, and the locking block 11 is located on the left side of the top of the locking rod 10. The locking block 11 has a trapezoidal shape. The return spring 12 is sleeved on the moving rod 9. The elastic sealing cover 3 has a limiting groove 13 at its left end. The limiting groove 13 has a trapezoidal shape. The elastic sealing cover 3 has a lifting block 14 at its top. The lifting block 14 has a rectangular shape.

[0022] Analysis of the above content: When sealing the elastic sealing cover 3, the operator presses the elastic sealing cover 3, which can then be inserted into the locking block 11. The locking block 11 can then be inserted into the limiting groove 13 inside the elastic sealing cover 3, thereby locking and limiting the elastic sealing cover 3. If it is necessary to open the elastic sealing cover 3, the operator can press the push button 8. Pressing the push button 8 pushes the moving rod 9, which drives the locking block rod 10. The locking block rod 10 can then push the locking block 11 out of the limiting groove 13 of the elastic sealing cover 3, and the elastic sealing cover 3 can then rebound through the spring hinge 4, thereby opening the sealing protrusion 16.

[0023] Example 2:

[0024] Please see Figure 1-2 The present invention provides a technical solution based on Embodiment 1: the bottom of the mounting cover 6 is provided with an outer sealing ring 17, the outer sealing ring 17 is in the shape of a ring, the top of the mounting cover 6 is provided with a sealing protrusion 16, the sealing protrusion 16 is located at the center of the mounting groove 15, the sealing protrusion 16 is in the shape of a cylinder, and the sealing protrusion 16 and the mounting cover 6 are in a through structure.

[0025] Analysis of the above content: During sealing, the elastic sealing cover 3 is inserted into the top of the mounting cover 6, then the bottom outer side of the elastic sealing cover 3 is inserted into the top outer side of the mounting cover 6, and then the center of the elastic sealing cover 3 is placed on the sealing protrusion 16, thereby achieving the purpose of double sealing.

[0026] Example 3:

[0027] Please see Figure 1-2 Based on Embodiment 1, this utility model provides a technical solution: a protective rubber sleeve 18 is installed on the surface of the test tube body 2, and the protective rubber sleeve 18 has a T-shaped structure.

[0028] Analysis of the above content: The protective rubber sleeve 18 can effectively protect the test tube body 2. For example, when the test tube body 2 is bumped, the protective rubber sleeve 18 can effectively achieve the purpose of cushioning and reduce the scratches on the test tube body 2. The T-shaped structure of the protective rubber sleeve 18 is to facilitate the staff to observe the internal condition of the test tube body 2 from the side without the protective rubber sleeve 18.

[0029] Working principle: During operation, when sealing the elastic sealing cover 3, the operator presses the elastic sealing cover 3, which can then be inserted into the locking block 11. The locking block 11 can then be inserted into the limiting groove 13 inside the elastic sealing cover 3, thereby locking and limiting the elastic sealing cover 3. If it is necessary to open the elastic sealing cover 3, the operator can press the push button 8. Pressing the push button 8 pushes the moving rod 9, which drives the locking block rod 10. The locking block rod 10 can then push the locking block 11 out of the limiting groove 13 of the elastic sealing cover 3, and the elastic sealing cover 3 can then rebound through the spring hinge 4, thereby opening the sealing protrusion 16.

[0030] To further demonstrate the novelty and authenticity of this solution, the following data is provided:

[0031] I. Efficiency data of single-handed press-to-open / close structure

[0032]

[0033] Data Explanation:
