Detailed Description

Referring to fig. 2 to 4, the present utility model provides a pipe repair structure including a cover portion 10, a joint portion 20, a fastener 30, and a gasket 40.

The cover part 10 is used for surrounding a pipeline, the cover part 10 is a C-shaped plate structural member, specifically, the cover part 10 is formed by bending a steel plate with the thickness of 0.8-1.2 mm, so that the cover part 10 is ensured to have certain rigidity, and bending and mounting difficulties of the cover part 10 can be reduced. The covering part 10 is provided with the notch 11 so as to divide the covering part 10 into at least two parts, the cutting direction formed in the notch 11 is perpendicular to the length direction of the covering part 10, the sealing gasket 40 is arranged on the inner circumferential surface of the covering part 10 and used for covering the damaged position of the pipeline, the two parts of the covering part 10 can be bent at the notch position, so that the covering part 10 can be attached to the bent pipe, the sealing gasket 40 can be fixed on the bent pipe, the tightness between the sealing gasket 40 and the pipeline is favorably increased, and the sealing property of the sealing gasket is improved.

The engaging portion 20 includes two oppositely disposed ear plates 21, the two ear plates 21 are respectively connected to the surrounding openings of the covering portion 10, and both ends of the two ear plates 21 are aligned with both ends of the covering portion 10. Alternatively, the two ear plates 21 and the cover portion 10 may be fixedly connected by welding or the like, and of course, the ear plates 21 and the cover portion 10 may also be integrally formed so as to be formed, specifically, the ear plates 21 are formed by bending the cover portion 10, and the ear plates 21 are flat plates.

The fasteners 30 are used to connect the two ear panels 21 to secure the cover 10 to the pipe. In one embodiment, the fastening member 30 may be a connecting member such as a rivet, and in another embodiment, the fastening member 30 may also be a bolt 31 and a nut 32 matching the bolt 31, specifically, when the fastening member 30 is a bolt 31 and a nut 32, the two lugs 21 are provided with fastening holes 22 aligned with each other, and the bolt 31 penetrates the fastening hole 22 from one side and is locked with the nut 32 of the other fastening hole 22, so as to fix the covering portion 10 on the pipe.

Alternatively, the slit 11 penetrates the radial direction of the cover 10 and extends to the ear plate 21 so that the entire cover 10 can be bent from the position of the slit 11. Since the two ear plates 21 are elongated, they have a constant bending rate, and the ear plates 11 can be bonded to the surface of the bent tube.

Further, the width of the slit 11 is 2mm to 3mm, and the width of the slit 11 is not preferably excessively large to secure the stability between the cover 10 and the bent pipe.
