Embodiment Construction

[0013] Hereinafter, in combination with preferred embodiments, the specific implementation manner provided according to the present invention is described in detail as follows: See the drawings for details, a plugging plug, including a flexible plugging plug 1 and a fastening bolt 2, the flexible plugging plug A through hole 3 is provided in the middle of the sub, and a fastening bolt with an ingot nut 4 penetrates through the through hole. The longitudinal cross-sectional shape of the flexible plugging plug is a truncated cone with an isosceles trapezoid. The flexible plugging plug is made of oil-resistant rubber or plastic or engineering plastics. The diameter of the lower bottom B of the flexible plugging plug is Φ16mm-Φ35mm, and the diameter of the upper bottom A is Φ8mm-Φ20mm. Washers 5 are respectively arranged between the two ends of the flexible plugging plug and the fastening bolt. The fastening bolt has an interference fit with the through hole, and its diameter is ...

Abstract

The invention relates to a plugging bolt, characterized in that a flexible plugging bolt and a fastening bolt are included, wherein said flexible plugging bolt is provided with a through hole in the middle, and a fastening bolt with a wing nut penetrates into the through hole. The invention has the advantageous effects as follows: the plugging bolt can be used for plugging broken holes with different materials and different sizes, convenient to operate, high in the repairing efficiency and low in the cost, and it can be used to plug various plates and cases fulfilled with liquid, and specifically suitable for fast plugging of small holes greater than 5mm of an automobile oil tank or water tank. A plurality of plugging bolts in different specifications can be carried for plugging anytime. The plugging bolt can effectively plug when a truck encounters the above problem during a long-distance transport at a desolate place. Thus, a vehicle on-site breaking-down can be prevented and the transport mission can be finished successfully.

Description

Technical field [0001] The invention belongs to a leakage plugging device, and particularly relates to a plugging plug used for plugging leaky plates or boxes. Background technique [0002] At present, containers made of various plates, especially metal plates, are prone to corrosion and leaks after long-term wind, rain, and sun exposure, causing liquid in the container to leak out, resulting in failure to work normally. The current repair methods include welding repair method, riveting method, glue repair method, plug repair method, etc. The disadvantage of welding repair method is that the surrounding materials are easily oxidized due to high temperature, leading to the formation of new and larger loopholes; The method cannot be used to rivet the leaks in the cabinet panel: the rubber patch method cannot implement the rubber patch for the leaks with moisture; the plug patch method is easy to fall off when plugging the leaks with high vibration intensity and large internal press...
