BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments;

[0013] Figure 1 It is a structural diagram of the utility model;

[0014] Figure 2 It is a cross-sectional view of the present utility model. DETAILED DESCRIPTION

[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0016] Reference Figure 1-2 This specific embodiment adopts the following technical solution: a rubber plunger, including a plunger body, the plunger body includes a hollow cylinder 1 and a nest 2, the top of the hollow cylinder 1 is embedded with the nest 2, and the cross-section of the nest 2 is I-shaped.

[0017] It is worth noting that there is a circle of circular grooves 21 in the middle of the nest 2, and the circular grooves 21 are embedded and matched with the inner edge 11 of the top of the hollow cylinder 1.

[0018] It is worth noting that a groove 22 is provided at the top center of the nest 2 .

[0019] It is worth noting that the nest 2 is made of ASTM D200050A15 F17 EF31 rubber.

[0020] In addition, the hollow cylinder 1 is made of 1008 / 1022 carbon steel.

[0021] The nest 2 of this specific embodiment adopts ASTM D200050A15 F17 EF31 rubber parts: this rubber material has good heat resistance, low temperature resistance and liquid resistance, and can maintain stable performance in various harsh working environments. The hollow cylinder 1 adopts 1008 / 1022 carbon steel: this carbon steel material has high strength and wear resistance, and can withstand high pressure and high wear working conditions. The cross-section of the nest 2 is I-shaped: this design can provide better support and stability, while reducing the amount of material used, reducing weight and cost. The circular groove 21 is embedded in the inner edge 11 at the top of the hollow cylinder 1; this embedded design can ensure a tight fit between the nest 2 and the hollow cylinder 1 to prevent leakage and loosening. Groove 22: The groove 22 is set in the center of the top of the nest 2 to provide additional sealing space and further enhance the sealing effect.

[0022] Since this specific embodiment uses high-strength carbon steel material and rubber parts with good elasticity, this plunger can withstand higher pressures and is suitable for applications in high-pressure environments. The wear resistance of carbon steel material can effectively reduce the wear of the plunger during long-term use and extend its service life. The design and embedded fit of the rubber nest can provide a good sealing effect to prevent liquid or gas leakage. The embedded fit between the nest 2 and the hollow cylinder 1 allows the various parts of the plunger to be independently disassembled and replaced, facilitating maintenance and care.

[0023] The rubber plunger in this embodiment combines the advantages of high-strength carbon steel and high-performance rubber materials, offering excellent pressure resistance, wear resistance, and sealing properties, making it suitable for a variety of harsh working environments. Its detachable design also facilitates maintenance and replacement, improving efficiency and cost-effectiveness.
