Comprising an upper fire hydrant body, a lower fire hydrant body, a connecting device, a lifting inner ring, an outer ring body and a buffer space, wherein the upper fire hydrant body and the lower fire hydrant body are arranged in a split manner; the connecting device is arranged between the upper fire hydrant body and the lower fire hydrant body; the lifting inner ring is arranged on the peripheral side of the lower fire hydrant body; and the elastic connecting piece is arranged between the lifting inner ring and the outer ring body and is positioned in the buffer space.

The present application relates to the technical field of decoration engineering, and discloses a gypsum board sealing device, which comprises a main body, the main body comprises at least one first protruding part and a second protruding part, the size of the main body is smaller than the size of a ceiling opening, the first protruding part is formed in the middle of the outer wall of the main body and protrudes outward, the second protruding part is formed in the lower part of the outer wall of the main body and protrudes outward, and the second protruding part is larger than the size of the ceiling opening. The main body can well block the ceiling opening, the first protruding part can provide better sealing effect, and the second protruding part can prevent the main body from falling off from the ceiling opening. The size of the main body of the gypsum board sealing device is smaller than the size of the ceiling opening, after the main body is placed in the ceiling opening, the main body can be completely in the ceiling opening, and the subsequent process construction will not be affected.

The utility model discloses a high-temperature-resistant and wear-resistant silica gel ball, and relates to a structural part of a common sieve. The utility model relates to the technical field of sieve cleaning or heating. The high-temperature-resistant and wear-resistant silica gel ball comprises a first hard silica gel layer, the rear side of the first hard silica gel layer is connected with a second hard silica gel layer, first soft silica gel is adhered to the inner surface of the first hard silica gel layer, second soft silica gel is adhered to the inner surface of the second hard silica gel layer, and the first hard silica gel layer and the second hard silica gel layer are adhered through heat vulcanization. The first soft silica gel and the second soft silica gel are also bonded through heat vulcanization, a first hollow groove is formed in the first soft silica gel, a second hollow groove is formed in the second soft silica gel, in this way, the interior of the silica gel ball can be arranged to be of a hollow structure with an elastic mechanism, and then the silica gel ball has a larger deformation space; and the elastic restoring force is enhanced, so that the elasticity of the silica gel ball is improved, the speed of removing blockages in the screen holes by the vibrating screen is increased, and the screening efficiency is improved.
