Detailed Description
The invention will now be further described with reference to the accompanying drawings. The drawings are simplified schematic diagrams only illustrating the basic structure of the present invention in a schematic manner, and thus show only the components related to the present invention.
Referring to fig. 1, the aluminum pipe connection sealing structure comprises a first aluminum pipe 1 and a second aluminum pipe 2, wherein an annular accommodating groove 3 is inwards recessed at the end part of one end of the first aluminum pipe 1, and an extending cylinder 4 matched with the inner diameter of the accommodating groove 3 outwards extends from the end part of the second aluminum pipe 2. The extension cylinder 4 is inserted into the receiving groove 3 and two aluminum pipes are connected by means of insertion.
As shown in fig. 1, an elastic gasket 7 is provided between the end of the extension cylinder 4 and the bottom of the receiving groove 3, and a buffer portion 71 having a triangular shape is provided on the elastic gasket 7 toward the inside of the first aluminum pipe 1. The elastic gasket 7 can compensate for the position deviation when the first aluminum pipe 1 and the second aluminum pipe 2 are installed, improve the installation accuracy, and simultaneously can buffer the impact between the first aluminum pipe 1 and the second aluminum pipe 2. The triangular buffer enables water flow to flow from any direction and can stop the flow speed of water in the aluminum pipe, so that the impact of the water flow on the aluminum pipe is reduced, and the service life of the aluminum pipe is prolonged.
As shown in fig. 2, the end of the extension tube 4 is recessed with a second groove 42, the second groove 42 is located on the outer side of the elastic pad 7, and the water-swelling water stop 6 is arranged in the second groove 42. Meet water inflation sealing rod 6 and carry out sealed for the first time to the aluminum pipe, meet water inflation sealing rod 6 and can the inflation deformation after meeting water, then be full of second recess 42 to produce huge contact pressure, prevent the seepage.
As shown in fig. 2, the end of the extension cylinder 4 is further recessed with a labyrinth groove 43, the labyrinth groove 43 is located outside the second groove 42, and the bottom of the receiving groove 3 is provided with a labyrinth ring 31 fitted to the labyrinth groove 43. The labyrinth ring 31 is embedded in the labyrinth groove 43, so that the flow direction of water is bent, the water is not easy to leak outwards, and the aluminum pipe is sealed secondarily.
As shown in fig. 2, a first groove 41 is annularly arranged on the outer side wall of the extension cylinder 4, and a sealing rubber ring 5 is arranged in the first groove 41. The sealing rubber ring 5 is used for sealing the aluminum pipe for three times, so that the sealing effect is further improved, and meanwhile, the sealing rubber ring 5 enables external water to be difficult to enter the aluminum pipe from the outside.
As shown in fig. 2, a drainage hole 44 is formed on the outer side wall of the extension cylinder 4, and the drainage hole 44 is located above the extension cylinder 4. When water enters the outer side wall of the extension cylinder 4, the water can be directly discharged from the water discharge hole 44 into the aluminum pipe, and at the same time, the water outside the aluminum pipe can also be discharged from the water discharge hole 44 into the aluminum pipe.
As shown in figure 2, the joint of the second aluminum pipe 2 and the extension cylinder 4 is provided with a guide inclined surface 21, and one end of the first aluminum pipe 1, which is positioned at the accommodating groove 3, is provided with an inner chamfer 11 matched with the guide inclined surface 21. The inner chamfer 11 and the guide inclined plane 21 are more convenient for the insertion connection of the first aluminum pipe 1 and the second aluminum pipe 2, and the installation of the first aluminum pipe 1 and the second aluminum pipe 2 is improved.
As shown in fig. 1, in order to improve the corrosion resistance of the first aluminum pipe 1 and the second aluminum pipe 2, a corrosion-resistant layer 8 is coated on the inner side walls of the first aluminum pipe 1 and the second aluminum pipe 2, and the corrosion-resistant layer 8 is preferably epoxy resin.
The specific implementation mode is as follows:
when the first aluminum pipe 1 and the second aluminum pipe 2 are connected in a plugging manner, the extension cylinder 4 is embedded into the accommodating groove 3, so that the guide inclined surface 21 is contacted with the inner chamfer 11, the elastic gasket 7 is clamped in the extension cylinder 4 and the accommodating groove 3, and the position deviation of the first aluminum pipe 1 and the second aluminum pipe 2 can be adjusted. When water in the aluminum pipe flows, the water is contacted with the elastic gasket 7, the flowing speed of the water is reduced, and the impact of the water flow on the inner wall of the aluminum pipe is reduced. The water-swelling water stop strip 6, the labyrinth groove 43, the labyrinth ring 31 and the sealing rubber ring 5 seal the connection part of the aluminum pipe layer by layer, so that the leakage phenomenon of the aluminum pipe is reduced.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
