Abstract

The invention discloses a plugging bolt. The plugging bolt comprises a bolt, wherein a flexible inner plugging plate is tightly matched with the part, adjacent to the inner side surface of a plug, on a threaded rod of the bolt; and corresponding to the inner plugging plate, a flexible outer plugging plate is tightly matched with a threaded rod on the inner side of a nut. One end of the outer side of the nut on the threaded rod is provided with a polygonal rotary chuck with the diameter no more than that of the threaded rod. The inner plugging plate and the outer plugging plate are discs which are made of an engineering plastic or glue model material, the outsides of the discs are provided with arc convex surfaces and the insides of the discs are provided with arc concave surfaces. The plugging bolt provided by the invention can be used for plugging broken holes which are made of different materials and are of different sizes; the plugging bolt has the advantages of convenience for operation, high repairing efficiency and low cost; and the plugging bolt is suitable for plugging panels and boxes which contain various liquids or gases.

Description

A kind of leak stopping bolt

Technical field:

The present invention is a kind of equipment special that leaky sheet material or casing are carried out leak stopping of being used for.

Background technique:

At present, the container that various sheet materials are made is particularly used sheet metal, for a long time through wind, drench with rain and Exposure to Sunlight, the formation leak that easily is corroded leaks outside liquid or gas in the container, causing can't proper functioning.Present repair mode has soldering method, riveting reinforcing method, glue reinforcing method, plug reinforcing method etc., and the shortcoming of existence is that the soldering method easily makes the material of periphery oxidized because of high temperature, causes new bigger leak to form; The riveting reinforcing method can not be carried out riveting to box plate face leak and be mended; The glue reinforcing method can't be implemented glue to the leak that moisture is arranged and mend; The plug reinforcing method presses the bigger leak plug added time easily to come off to the ocsillator strenght imperial palace.

Summary of the invention:

The object of the invention provides a kind of leak of various sheet materials, casing and different size that is applicable to and carries out leak stopping, is having or not the leak stopping bolt that all can repair under the situation of moisture.

Technological scheme of the present invention is finished as follows, it includes a bolt, it is characterized in that: on the screw rod of bolt, stifled dish in the flexibility is arranged, tighten with the corresponding screw rod of interior stifled dish and be combined with stifled dish outside the flexibility in the nut inboard by plug inner side surface drive fit.Be provided with the polygonal rotation chuck that a diameter is not more than screw rod at the screw rod upper cap nut outside one end.Inside and outside stifled dish is the curved convex surface in the outside that engineering plastics or glue moulding material make, the disk of inboard curved concave surface.The present invention can be used for the leak stopping of various different materials, different big or small holes, has easy to operately, and repairing efficiency height, the advantage that cost is low are applicable to sheet material, the casing leak stopping of various dress liquid or gas.

Description of drawings:

Fig. 1 is a kind of structural representation of the present invention.

Embodiment:

Describing embodiment in detail in conjunction with above accompanying drawing, as shown in drawings, is a kind of structural representation when being used to repair big small opening.It is to lean on plug 1 inner side surface drive fit therefrom to feel at ease on the screw rod 3 of a bolt to adorn stifled dish 2 in the flexibility, drive fit is equipped with stifled dish 4 outside the flexibility on the screw rod of corresponding inboard at nut 5 with interior stifled dish, inside and outside stifled dish is the curved convex surface in the outside of engineering plastics or injection moulding of glue moulding material or compression moulding, the disk of inboard curved concave surface, be provided with the square rotation chuck 6 that a diameter is not more than screw rod at the screw rod upper cap nut outside one end, can conveniently firmly tighten the screw rod rotating nut the stifled dish in the interior outside is clamped on the sheet material at small opening place.If be coated with the thick blocking agent of last layer 0.05mm between inside and outside stifled dish and small opening place sheet material when leak stopping, then plugging effect is better.

Claims

1. leak stopping bolt, it includes a bolt, it is characterized in that: by plug inner side surface drive fit stifled dish in the flexibility is arranged on the screw rod of bolt, tighten with the corresponding screw rod in the nut inboard of interior stifled dish and be combined with stifled dish outside the flexibility.

2. a kind of leak stopping bolt as claimed in claim 1 is characterized in that: be provided with the polygonal rotation chuck that a diameter is not more than screw rod at the screw rod upper cap nut outside one end.

3. as claim 1,2 described a kind of leak stopping bolts, it is characterized in that: inside and outside stifled dish is the curved convex surface in the outside that engineering plastics or glue moulding material make, the disk of inboard curved concave surface.
