Detailed Description

The utility model relates to a quick sealing device, which comprises a convex sealing gasket and a fixing device, wherein the convex sealing gasket is used for sealing a leakage part; the fixing device is used for fixing the convex sealing gasket.

The following description will be made in detail with reference to the drawings and preferred embodiments of the present invention.

Example 1

As shown in fig. 3, the convex gasket 3 is made of rubber, and includes a planar portion 31 and a convex portion 32 disposed on the planar portion 31, and the convex portion 32 is a hemisphere, so that when plugging, the elastic convex portion 32 can partially enter the leak, thereby sealing the leak more tightly.

As shown in fig. 1 and 2, the fixing device comprises an upper die 2 and a lower die 1, wherein the upper die 2 and the lower die 1 are both semi-annular structures of semi-hollow circles, a hollow accommodating cavity is formed after the upper die 2 and the lower die 1 are butted, so that a pipeline to be repaired is hooped tightly, and the convex sealing gasket 3 is attached to the hollow accommodating cavity for plugging. A joint is respectively extended from two ends of the semi-annular structures of the upper die 2 and the lower die 1, the joint is a plane structure in the embodiment, an upper die plane structure 21 is extended from the upper die 2, and a lower die plane structure 11 is extended from the lower die 1. When in connection, the plane structures of the upper die 2 and the lower die 1 are attached together, detachable connecting devices are arranged on the upper die plane structure 21 and the lower die plane structure 11, the connecting device at one end is of a clamping structure, and the connecting device at the other end is of a clamping device. Two rectangular through holes are formed in an upper die plane structure 21 at the clamping structure end, two rectangular convex strips 12 are arranged on a lower die plane structure 11, the rectangular convex strips 12 penetrate through the rectangular through holes, and the clamping structure can prevent the lower die 1 and the upper die 2 from generating relative displacement in the horizontal direction. The clamping device end comprises a clamping handle 4 and a fastening nut 5, threaded through holes are formed in an upper die plane structure 21 and a lower die plane structure 11, the clamping handle 4 is composed of a rotating handle and a screw rod, the clamping handle 4 is installed in the threaded through holes, the fastening nuts 5 are installed above the upper die plane structure 21 and below the lower die plane structure 11 respectively on the clamping handle 4, and the lower die 1 and the upper die 2 can be tightly attached together by screwing the fastening nuts 5.
