Description

plug

technical field

The utility model belongs to a leak-stopping device, in particular to a leak-stopping plug used for leak-stopping boards or boxes with leaks.

Background technique

At present, containers made of various plates, especially metal plates, are easily corroded to form holes after being exposed to wind, rain and sun for a long time, causing the liquid in the container to leak out, resulting in failure to work normally. The current repair methods include welding repair method, riveting repair method, glue repair method, plug repair method, etc. The disadvantage is that the welding repair method is easy to oxidize the surrounding materials due to high temperature, resulting in the formation of new and larger loopholes; riveting repair The method cannot rivet the loopholes on the box body surface: the glue patching method cannot implement glue patching for the loopholes with moisture; the plug patching method is easy to fall off when the loopholes with high vibration intensity and large internal pressure are patched. Especially the leaks in the fuel tank of automobiles, because gasoline is a solvent and is flammable, the methods such as welding repair method, riveting repair method, glue repair method, etc. cannot be solved in time. If the above-mentioned problems are encountered on the way of long-distance transport vehicles, there is no effective way to plug the leaks, and the vehicles can only break down on the spot, which directly affects the completion of the transport task. Application number (201110194509.0) discloses a leak plug, which includes a bolt, on the screw rod of the bolt, there is a flexible inner plug tightly fitted on the inner side of the plug, corresponding to the inner plug on the screw rod inside the nut The tight fit has a flexible outer plugging disc. A polygonal rotating chuck with a diameter not larger than the screw rod is provided at the outer end of the nut on the screw rod. Both the inner and outer plugging discs are made of engineering plastics or plastic-plastic materials, and are circular discs with an arc-shaped convex surface on the outside and an arc-shaped concave surface on the inside. The invention can be used for plugging holes of different materials and sizes, has the advantages of convenient operation, high repair efficiency and low cost, and is suitable for plugging various plates and boxes containing liquid or gas. This device volume is too large, only has the small hole of more than 8mm for the diameter of vehicle fuel tank or water tank and can't be used.

Utility model content

The utility model aims to overcome the deficiencies in the prior art, and provides a plugging plug for plugging leaky tanks, especially suitable for rapid plugging of small holes above 5mm in automobile fuel tanks or water tanks.

In order to achieve the above object, the utility model is realized through the following technical scheme, a leak plug, which is characterized in that: it includes a flexible plug and a fastening bolt, and a through hole is arranged in the middle of the flexible plug, and Fastening bolts with ingot nuts run through the through holes.

The cross-sectional shape of the flexible plugging plug on the longitudinal axis is an isosceles trapezoidal truncated cone.

The flexible plugging plug is made of oil-resistant rubber or plastic material or engineering plastic.

The diameter of the lower bottom of the flexible plugging embolus is 16mm-Φ35mm, and the diameter of the upper bottom is Φ8mm-Φ20mm.

Washers are respectively arranged between the two ends of the flexible plugging plug and the fastening bolts.

The fastening bolt is in interference fit with the via hole, and its diameter is Φ3mm-Φ5mm.

Beneficial effects: it can be used for leak plugging of various materials and holes of different sizes, and has the advantages of convenient operation, high repair efficiency and low cost, and is suitable for leak plugging of various plates and boxes containing liquid or gas. It is especially suitable for quick plugging of small holes above 8mm in automobile fuel tanks or water tanks. A number of plugging plugs of different specifications can be carried with the vehicle to plug the leak at any time. If the above-mentioned problems are encountered on the way of the long-distance transport vehicle, the leak can still be effectively blocked by "not going to the village or going to the shop" to avoid the vehicle from breaking down on the spot. Ensure the smooth completion of transportation tasks.
