[0021] Figure 2 It is a half-section view of this application. DETAILED DESCRIPTION

[0022] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] A self-extruding plugging cover, comprising

[0024] The cover 1 includes an opening 11, a bottom 12, an outer portion 13 provided on the bottom 12 and used to be sleeved on the outer periphery of the tube body, and an inner plug portion 14 used to be inserted into the tube body. A cavity 15 for inserting the tube body is formed between the outer portion 13 and the inner plug portion 14;

[0025] A boost ring 131 is provided on the inner wall of the outer portion 13 , and a blocking ring 141 is provided on the outer wall of the inner plug portion 14 . Both the boost ring 131 and the blocking ring 141 protrude toward the cavity 15 .

[0026] The utility model provides a self-extruding plugging cover. After the tube body is inserted into the cavity, the inside of the tube body is sealed by the plugging ring, and the outside of the tube body is tightly pressed by the boosting ring, thereby achieving a double anti-leakage effect. The outer portion can also serve as a fulcrum for easy pulling out.

[0027] Furthermore, as a preferred embodiment of this solution but not limiting, the cross section of the boosting ring 131 is in the shape of a right-angled trapezoid, with its oblique side facing the opening 11. The oblique side facilitates the insertion of the tube, and the right-angle side facilitates leakage prevention.

[0028] Furthermore, as a preferred embodiment of this solution but not a limitation, multiple blocking rings 141 are spaced apart along the axis of the inner plug 14 to form a sealing section, and the boosting ring 131 is disposed around the outer periphery of the sealing section. When the tube is inserted into the cavity, the inner plug first enters the tube and presses against it, and then the boosting ring presses against it, avoiding simultaneous resistance and facilitating insertion of the tube.

[0029] Furthermore, as a preferred embodiment of this solution but not limiting, the cross section of the blocking ring 141 is in the shape of a right triangle, with its hypotenuse facing the opening 11, so as to facilitate insertion into the tube body.

[0030] Furthermore, as a preferred embodiment of this solution but not limiting, the inner plug portion 14 is provided with an inner cavity 142, the diameter of which gradually increases from the opening 11 of the inner cavity 142 to the bottom 12. This increases the supporting force of the inner plug portion, and as the tube is inserted, the plugging ring gradually becomes less likely to be squeezed into the inner cavity, thereby gradually improving the sealing effect.

[0031] Furthermore, as a preferred embodiment of this solution but not limiting, the outer diameter of the outer portion 13 gradually increases along the direction from the opening 11 of the cavity 15 to the bottom 12. The outer portion is formed into an inverted frustum, which facilitates gripping and pulling out the cover, while also increasing support for the booster ring and improving the sealing effect.

[0032] Furthermore, as a preferred embodiment of this solution but not limiting, an anti-slip strip 16 is provided on the outer wall of the peripheral portion 13 along its length to increase friction and facilitate screwing into the cover.

[0033] Furthermore, as a preferred embodiment of this solution but not limiting, the end of the inner plug 14 is provided with a guide section 143, and the guide section 143 and the blocking ring 141 are arranged in sequence from the opening 11 to the bottom 12, so as to facilitate alignment with the inner cavity of the tube.

[0034] Furthermore, as a preferred embodiment of this solution but not limiting, a first enclosing ring 17 made of stainless steel is embedded in the outer portion 13, and the first enclosing ring 17 is provided corresponding to the boosting ring 131 to improve the pressure resistance and enhance the sealing performance.

[0035] Furthermore, as a preferred embodiment of this solution but not limiting, a second encircling ring 18 made of stainless steel is embedded in the inner plug portion 14, and the second encircling ring 18 is provided corresponding to the sealing section to improve pressure resistance and enhance sealing performance.

[0036] The above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application. Other embodiments whose principles and basic structures are the same or similar to those of the present application are within the scope of protection of the present application.
