Abstract

The invention relates to a combined sealing strip for an underwater cabin observation window. The combined sealing strip comprises a male sealing strip and a female sealing strip which are connected in a matched way. The cross section of the male sealing strip is in the shape of an inverted T, a protruding connecting end is formed on an upper part of the male sealing strip, a cavity is made in theprotruding connecting end, and U-shaped grooves are symmetrically formed in two side walls of the lower part of the male sealing strip. The cross section of the male sealing strip is in the shape ofa letter U, a sealing and embedding groove adapted to the protruding connecting end of the male sealing strip is formed in the female sealing strip, and a vibration damping chamber is arranged in themiddle of the female sealing strip, lip-shaped grooves are symmetrically formed on two sides of a lower part of the female sealing strip, end grooves are formed at a root of the protruding connectingend on the male sealing strip, and ribs adapted to the end grooves of the male sealing strip are formed on two side groove wall ends of the sealing and embedding groove. According to the combined sealing strip, the male sealing strip and the female sealing strip are matched and connected in the form of plugging, the overall sealing of an observation window is ensured, and the vibration damping effect is greatly improved.

Example Embodiment

[0018] The present invention will be further described in detail below with reference to the drawings and specific embodiments. The following embodiments are only descriptive and not restrictive, and the protection scope of the present invention cannot be limited by this.
[0019] The general idea of ​​the present invention is to provide a combined sealing strip for the observation window of the launch tank. By dividing the sealing strip into a male sealing strip and a female sealing strip, and using the plug-in form to cooperate and connect, the observation window is guaranteed The overall tightness.
[0020] A combined sealing strip for the observation window of the launch tank, comprising a male sealing strip 7 and a female sealing strip 6 which are matched and connected. The male sealing strip and the female sealing strip are respectively installed in the observation window hole and the observation window glass wall Above, when the observation window glass is installed, the sealed connection is realized through the mating connection between the arc convex block of the male sealing rubber strip and the sealing embedding groove of the female sealing rubber strip.
[0021] The cross section of the male sealing rubber strip is in the shape of "convex", one end of which is provided with a protruding connecting end 12, the protruding connecting end is an internally hollowed arc bump, and the inside is hollowed out, and the hollowed out is a cavity 11. When the male sealing strip and the female sealing strip are connected and installed, it not only strengthens its own elasticity, but also plays a role of damping; the other end of the male sealing strip has a first mounting part, The middle of the end face of the first mounting part is provided with a first slot 8 with an arc-shaped cross section, and a U-shaped slot 9 is uniformly formed in the middle of the symmetrical side wall of the first mounting part. The symmetrical U-shaped slot and the first slot are arranged , So that the first mounting part forms a double-layer sealing structure, and the male sealing strip is sealed and embedded in the observation window hole through the first clamping groove and the U-shaped groove. When the male sealing strip and the female sealing strip are connected and installed, Due to mutual squeezing, the end faces on both sides of the card slot are close to the inner surface of the observation window hole to form an internal end face seal. In order to make the seal tighter, end face grooves 10 are symmetrically formed at the roots of both sides of the arc convex block. The shaped groove forms a better elastic pre-tightening sealing force, thereby realizing the sealing of the surface of the observation window.
[0022] The cross section of the female sealing strip is in the shape of "concave", and one end of the mother sealing strip body is formed with a sealing embedding groove 4, and the ends of the groove walls on both sides of the sealing embedding groove are formed with end faces with the male sealing strip. Groove matching convex strip 5, when the female sealing strip and the male sealing strip are connected and installed, the convex strip of the female sealing strip is embedded in the end groove of the male sealing strip to realize the sealing of the overall sealing strip Stability; the other end of the mother sealing strip is made with a second mounting part, the middle of the end surface of the second mounting part is made with a second slot 1 with an arc-shaped cross section, in the middle of the side wall of the second mounting part There is a lip-shaped groove 2 in the uniformly symmetrical system. A gap is provided in the female sealing strip at the position between the second mounting part and the sealing embedding groove, and the inside is hollowed out as a damping cavity 3. The arrangement of the groove makes the second mounting part also form a double-layer sealing structure. When it is connected and installed with the male sealing strip, it not only strengthens its own elasticity, but also plays a role of damping vibration; the female sealing strip passes The second card slot and the lip-shaped groove sealing card are embedded on the viewing window glass installation plate. When the male sealing strip and the female sealing strip are connected and installed together, the lip-shaped grooves increase its holding capacity and form an end face due to mutual extrusion. seal.
[0023] The arc convex block of the male sealing rubber strip is inserted into the sealing embedding groove of the female sealing rubber strip in the form of plugging, and the convex strip of the female sealing rubber strip is embedded in the end groove of the male sealing rubber strip due to the extrusion , Realize the surface sealing ability of the integral sealing strip.
[0024] The protruding distance of the protruding connecting end of the present invention is equal to the recession distance of the sealing embedding groove. A chamfer is provided in the opening of the sealing embedding groove of the female sealing rubber strip, so that the arc convex block of the male sealing rubber strip is inserted There is a gap in the side wall of the female sealing tape when the seal is embedded in the groove, which not only facilitates the installation of the male sealing tape into the female sealing tape, but also provides a deformation distance for the deformation of the male sealing tape, preventing it from breaking, and extending the overall seal The service life of the tape.
[0025] Further, the first mounting part and the second mounting part of the male sealing rubber strip are respectively located on the opposite outer sides of the mating connection of the male sealing rubber strip and the female sealing rubber strip. The protruding connecting end of the male sealing strip is hollowed out, and the second mounting part of the female sealing strip is hollowed out. Through the hollow setting, the male sealing strip and the female sealing strip can have better elasticity. When connecting, it makes the installation more convenient, and the hollow setting is used to strengthen the overall elasticity. When the glass is impacted by changes in water pressure, the gap between the glass and the installation groove changes, the male and female sealing strips can When elastic deformation occurs, the stability of the connection is always ensured and the sealed connection is ensured.
[0026] Although the embodiments and drawings of the present invention are disclosed for illustrative purposes, those skilled in the art can understand that various substitutions, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims Therefore, the scope of the present invention is not limited to the content disclosed in the embodiments and drawings.
