Detailed Description
The essential features and advantages of the invention will be further explained below with reference to examples, but the invention is not limited to the embodiments listed.
As shown in fig. 1 to 4, the concrete impermeability tester of the embodiment includes a base 1 and an upper cover 2, and a sealing assembly is disposed between the base 1 and the upper cover 2. The sealing assembly comprises a bottom plate 3 and a sealing part 4, wherein the bottom plate 3 comprises a plate body 31 and a convex part 32, the plate body 31 is annular, and a hollow part 33 is formed in the middle of the plate body 31. The convex portions 32 are provided on both sides of the plate body 31 and have a ring shape. The sealing portion 4 includes a connecting groove 41, an inner annular surface 42 and an outer annular surface 43, the plate body 31 is disposed in the connecting groove 41, and the plate body 31 is fixedly connected to the base 1. The inner ring surface 42 has a first protruding ring 421, the outer ring surface 43 has a second protruding ring 431, the first protruding ring 421 and the second protruding ring 431 are located above the plate body 31, and when the upper cover 2 is folded with the base 1, the first protruding ring 421 and the second protruding ring 431 are respectively contacted with the slot 21 of the upper cover 2. In the technical scheme, the bottom plate 3 is arranged, so that the structural strength of the sealing part can be enhanced, and meanwhile, the sealing part is convenient to connect with the base; the bottom plate 3 in this embodiment is made of a metal material, and the seal portion 4 is made of a rubber material. Further, the strength of the bottom plate can be enhanced by providing the convex portion 32. Through setting up first bulge loop 421 and second bulge loop 431 for can support when the upper cover is installed and press first, second bulge loop, make and form a plurality of contact surfaces between upper cover and slot, thereby realize that the multilayer is sealed, promote the leakproofness.
