Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.
As shown in fig. 1-3: the metal waterproof quick corrugated pipe fixing joint comprises a metal main body 3, a rubber sheath 4 and a corrugated pipe clamping sleeve 5; the metal main body 3 is provided with a step hole, and the rubber sheath 4 is arranged in the metal main body 3 and is abutted against the step surface; bellows cutting ferrule 5 suit is in 6 tip of bellows, and the downthehole fixings of step that inserts in metal master 3 make bellows 6 compress tightly rubber sheath 4 and seal.
In this embodiment, the rubber sheath 4 is a tapered sleeve, and the bellows 6 is pressed at the end with a larger caliber of the rubber sheath 4, and because the rubber sheath 4 is designed to be tapered, compression deformation in two axial and radial directions is generated when the bellows is pressed, so that the bellows is more favorable for sealing a gap between the bellows 6 and the metal main body 3, and the sealing effect is improved.
In the embodiment, the side wall of the corrugated pipe clamp sleeve 5 is provided with a plurality of reeds 8, the inner side surface and the outer side surface of each reed 8 are respectively provided with a clamping table, and the inner wall of the metal main body 3 is provided with a clamping groove 7 corresponding to the clamping table on the outer side surface of each reed 8; the card platform card of reed 8's medial surface is in the recess on 6 surfaces of bellows, earlier with 5 suits of bellows cutting ferrule on bellows 6, utilizes the elasticity of reed 8 to make its inboard card platform card 6 surfaces of bellows, inserts metal main part 3 with bellows cutting ferrule 5 and bellows 6 together again in, the card is in draw-in groove 7 department, simple structure, stability, convenient equipment.
In this embodiment, the reed 8 is formed by forming a U-shaped hole in the side wall of the corrugated pipe ferrule 5, and the part surrounded by the U-shaped hole forms the reed 8, so that the integrity is good and the processing is easy.
In this embodiment, still include metal nut 1 and rubber gasket 2, metal nut 1 and the external screw thread department of rubber gasket 2 suit in the outer end of metal main part 3, and metal nut 1 passes through threaded connection in the external screw thread of metal main part 3, and during the installation, metal main part 3 fastens in EMUs carriage main part through metal nut 1 to utilize rubber gasket 2 to play effectual shockproof effect.
