[0033] Embodiment 1

[0034] Combine the following Figure 1-Figure 2 , Fig. 9 The utility model describes an EP tube explosion-proof cover clamp, the EP tube 20 includes a tube body 21, the top of the tube body 21 has a tube mouth 22, the tube mouth 22 is provided with a tube cover 23, the tube cover 23 has an opening portion 24 and a hinge portion 25, the hinge portion 25 is connected to the tube body 21, and the opening portion 24 and the hinge portion 25 both have a portion protruding from the outer wall of the tube body 21. The clamp includes a main body 10, which is made of a highly elastic flexible material. A first fixing hole 11, a second fixing hole 12 and a third fixing hole 13 are sequentially opened along the length direction of the main body 10, and a clamping section 14 is provided between the second fixing hole 12 and the third fixing hole 13; wherein, when the main body 10 is configured to clamp the EP tube 20, the first fixing hole 11 is sleeved on the tube body 21, the second fixing hole 12 is located at the position of the opening 24, at least a part of the opening 24 is located in the second fixing hole 12, the third fixing hole 13 is located at the position of the hinge 25, at least a part of the hinge 25 is located in the third fixing hole 13, and the clamping section 14 is tightly attached to the upper surface of the tube cover 23 to form a clamp structure surrounding the tube cover 23. The EP tube 20 is also called a centrifuge tube, and its tube mouth 22 is usually provided with a tube cover 23 for sealing the tube body 21. In order to prevent the tube cover 23 from breaking open due to high temperature or other factors during operation, the tube cover 23 is usually limited to ensure that the tube cover 23 will not separate from the tube mouth 22. In this embodiment, when pressing, the main body 10 protects the tube cover 23 so that the pressing section 14 can apply pressure to the tube cover 23, thereby achieving a fastening and limiting effect on the tube cover 23 to prevent the tube cover 23 from breaking open. The overall structure is simple, the manufacturing cost is low, the service life is long, and the installation and disassembly are convenient.

[0035] The main body 10 is made of a flexible material, so each fixing hole has a high expansion capacity, and the main body 10 is bent to embrace the pipe cover 23. Figure 2As shown, the first fixing hole 11 is sleeved on the tube body 21 and is close to the position of the tube mouth 22, the second fixing hole 12 is located on one side of the opening 24, and the protruding part of the opening 24 is located in the second fixing hole 12, and then the pressing section 14 is located on the upper surface of the tube cover 23, and then one end of the third fixing hole 13 is pulled so that the third fixing hole 13 is located on one side of the hinge part 25, and the main structure of the hinge part 25 is located through the third fixing hole 13, so that the entire main body 10 covers the tube cover 23, thereby realizing the pressing of the tube cover 23. That is, by stretching the main body 10, the pressing section 14 can apply downward pressure to the tube cover 23, ensuring the stability of the sealing of the tube cover 23.

[0036] It is understandable that the ambient temperature usually does not exceed 120°C during operation, which prevents the flexible material of the main body 10 from plastic deformation, thereby ensuring the tightening effect. In addition, the capacity of the EP tube 20 is usually small, which limits the pressure of the internal heated gas. Through experiments, the flexible material can be compressed. The main body 10 made of flexible material is conducive to rapid disassembly and assembly, and on the other hand, it has high toughness and can be reused, which prevents aging and has a long service life, reducing the cost of use.

[0037] In the specific setting, the main body 10 is constructed as a rectangular block structure, and the rounded corners are processed on each corner of the rectangular block. The width of the main body 10 is greater than or equal to the diameter of the tube cover 23, which enables the main body 10 to completely cover the tube cover 23 and improve stability. Specifically, the main body 10 is about 1-2 cm long, 0.8-1 cm wide, and 0.1-0.2 cm thick, and the aperture of the first fixing hole 11 is smaller than the outer diameter of the tube body 21, the aperture of the second fixing hole 12 is smaller than the size of the protruding part of the opening 24, and the aperture of the third fixing hole 13 is smaller than the size of the hinge 25, which makes each fixing point more stable, thereby improving the stability of the clamp. In a further example, the aperture of the first fixing hole 11 can be arbitrarily adapted between 4-12 mm, so that the centrifuge tube explosion-proof clamp can adapt to EP tubes 20 of multiple models and sizes.

[0038] In specific applications, the flexible material is one of silicone, rubber, and latex. Of course, it can also be other medical-grade flexible materials to avoid pollution and potential harm.

[0039] According to an embodiment of the present invention, a marking through hole 141 is provided on the pressing section 14. The marking through hole 141 is directly opposite to the tube cover 23, so that it is convenient to identify the label on the tube cover 23.

[0040] According to an embodiment provided by the utility model, the hole shapes of the first fixing hole 11, the second fixing hole 12 and the third fixing hole 13 are one or more combinations of circular holes, triangular holes or strip holes. They have different sizes at different positions, so different hole shapes can be used to adapt to different positions, thereby improving the stability of the fixing point.

[0041] When setting specific Figure 1 As shown, the first fixing hole 11 is configured as a round hole, the second fixing hole 12 is configured as a triangular hole, and the third fixing hole 13 is configured as a buckle point hole, so as to achieve stable fastening at different positions.

[0042] According to an embodiment provided by the utility model, a gripping portion 15 for manual gripping is provided at one end close to the third fixing hole 13. The gripping portion 15 is configured as a triangular structure, and the gripping portion 15 can be conveniently gripped manually during installation and removal.

[0043] In a preferred embodiment, both sides of the first fixing hole 11 and both sides of the pressing section 14 are provided with flexible protrusions 16, and the flexible protrusions 16 are used to seal the gap between the tube cover 23 and the tube mouth 22 when pressing. When the clamp is clamped, that is, when pressed by the clamp, the first fixing hole 11 is located on the tube body 21 below the tube cover 23, and the pressing section 14 is located on the upper part of the tube cover 23. At this time, the upper and lower flexible protrusions 16 can fit together to achieve the sealing of the gap between the tube mouth 22 and the tube cover 23 of the EP tube 20, thereby improving the overall sealing and avoiding the loss of the cover during the hot and cold alternation process and the internal seepage pollution.

[0044] In specific examples, such as Figure 3-5 As shown, the flexible protrusion 16 can be a strip-shaped structure or a tooth-shaped structure. In the tooth-shaped structure, sealing is achieved by mutual meshing of the upper and lower parts.

[0045] According to an implementation mode provided by the utility model, Figure 8 As shown, the explosion-proof cover clamp includes a plurality of main bodies, which are arranged in parallel, and a hollow structure 30 is provided between adjacent main bodies, so that the adjacent main bodies can be folded. In some common scenarios, a plurality of EP tubes are arranged in a regular manner. In this embodiment, by arranging a plurality of main bodies, a plurality of EP tubes can be operated simultaneously, thereby improving the operation efficiency.

[0046] During specific processing, a plurality of arranged main body structures are formed on a whole piece of material, and then a hollow structure 30 is processed between adjacent main bodies, so that adjacent main bodies can be folded with the hollow structure 30 for easy storage and placement.

[0047] The specific installation process is as follows: Figure 2As shown, first, the first fixing hole 11 is put on the position of the hinge part 25, and the holding part 15 is pinched, and the first fixing hole 11 is stretched to make it fit on the tube body 21, and the first fixing hole 11 is close to the position of the tube mouth 22. Then, the holding part 15 is pinched to sequentially put the second fixing hole 12 on the opening part 24, and stretched backward so that the pressing line section is located at the tube cover 23, and the third fixing hole 13 is buckled on the main body of the hinge part 25, thereby completing the installation.

[0048] During the installation process, the first fixing hole 11 can also be inserted from the bottom of the tube body 21 , and then the main body 10 is moved upward so that the first fixing hole 11 reaches a position close to the tube opening 22 .

[0049] The specific disassembly process is as follows: Figure 2 As shown, pinch the holding portion 15 and gently lift it upward, so that the third fixing hole 13 is separated from the hinge portion 25, and then the second fixing hole 12 is separated from the opening portion 24 in turn along the reverse direction of the installation path, and the holding portion 15 is pulled to stretch the first fixing hole 11, so that the first fixing hole 11 is separated from the tube body 21.

[0050] Embodiment 2

[0051] According to another embodiment provided by the utility model, Figure 6 , Figure 7 As shown, the clamp includes a main body 10, and a first fixing hole 11, a second fixing hole 12 and a third fixing hole 13 are sequentially opened along the length direction of the main body 10, and a clamping section 14 is provided between the second fixing hole 12 and the third fixing hole 13. The main body 10 is made of a hard material, and a flexible portion 17 is provided around the aperture of the first fixing hole 11, the second fixing hole 12 and the third fixing hole 13, and a first bending portion 110 is provided between the first fixing hole 11 and the second fixing hole 12, a second bending portion 120 is provided between the second fixing hole 12 and the clamping section 14, and a third bending section 130 is provided between the clamping section 14 and the third fixing hole 13. In this embodiment, the general structure of the clamp is the same as that of the first embodiment, and the clamp in the second embodiment can also be installed and disassembled in the same manner as the embodiment, which will not be repeated here, and the differences between the second embodiment and the first embodiment will be explained below.

[0052] In this embodiment, the main body 10 is made of hard plastic, and a flexible portion 17 is provided around the edge of each fixing hole, so that each fixing point can be fixed through the flexible portion 17. In order to bend the hard plastic parts at the edge, a first bending portion 110, a second bending portion 120 and a third bending portion 130 are provided on the main body 10, and during installation and removal, the bending portions are bent to form an embracing structure.

[0053] In a specific embodiment, the bending portion may be a flexible connector, or a fold may be processed at each bending portion of the hard material. Specifically, the fold may be a thin sheet-shaped connector.

[0054] In a specific application, the material of the flexible portion 17 is one of silicone, rubber, and latex. The arrangement of the flexible portion 17 can facilitate the connection at the fixed point.

[0055] In this embodiment, the main structure of the main body 10 is made of hard material, so that each fixing hole can be adapted to an EP tube with a similar diameter. When installing this example, the first fixing hole 11 is inserted upward from the bottom of the tube body 21. After the first fixing hole 11 is installed to the specified position, the gripping part 15 is pinched to sequentially cover the second fixing hole 12 on the opening part 24, and stretched backward so that the pressing line section is located at the tube cover 23, and the third fixing hole 13 is buckled on the body of the hinge part 25, thereby completing the installation.
