Detailed Description
For better understanding of the objects, technical solutions and technical effects of the present invention, the present invention will be further explained with reference to the accompanying drawings and embodiments. It is to be noted that the following examples are only for explaining the present invention and are not intended to limit the present invention.
It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present, and when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
The terms "upper", "lower", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positions based on the orientations or positions shown in the drawings, and are for convenience of description only and should not be construed as limiting the technical solution. The meaning of "a number" is two or more unless specifically defined otherwise.
As shown in fig. 1 and 2, a sealing and waterproof structure for a caulking groove of a pipe piece comprises a waterproof filling layer 1 filled in the caulking groove 103, a sealing rubber strip 2 is arranged in the caulking groove 103, the sealing rubber strip 2 is located between the waterproof filling layer 1 and the caulking groove 103, one side, close to the waterproof filling layer 1, of the sealing rubber strip 2 is an arc surface 22, and one side, close to the caulking groove 103, of the sealing rubber strip 2 is a plane 21.
The utility model discloses earlier at embedding joint strip 2 in caulking groove 103, pack waterproof filling layer 1 in caulking groove 103 remaining space again, constitute new caulking groove 103 waterproof seal structure, because joint strip 2's waterproof seal nature is better, can promote the water-proof effects of caulking groove 103 department, and joint strip 2 has certain elasticity, can pack firmly into in the caulking groove 103.
