Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides an embodiment: the utility model provides a pipe fitting with buffer function, including bolster 1, outer pipe fitting 2 and interior pipe fitting 4, the outside of interior pipe fitting 4 is fixed with outer pipe fitting 2, outer pipe fitting 2 can protect interior pipe fitting 4, the condition of damage can not appear in the assurance interior pipe fitting 4, the both ends of interior pipe fitting 4 all movable mounting have bolster 1, through coupling mechanism 12 mutual installation between bolster 1 and the interior pipe fitting 4, under coupling mechanism 12's effect, can dismantle the maintenance to bolster 1, the installation of the bolster 1 of also being convenient for simultaneously, the inside of bolster 1 all is fixed with buffer gear 9, buffer gear 9 inside bolster 1 can carry out certain buffering decompression to the water of intaking the pipe fitting, guarantee that the pressure of rivers can not too big break through the pipe fitting.

Further, be connected through spring 3 between outer pipe fitting 2 and the inner pipe fitting 4, when pipe fitting 4 in the rivers punching press, inner pipe fitting 4 can have power extrusion spring 3, and spring 3 produces the reverse effort and reduces the impact force of rivers to further cushion rivers.

Further, buffer gear 9 includes axostylus axostyle 7 and rubber buffering circle 8, and rubber buffering circle 8 is installed in the surface rotation of axostylus axostyle 7, and when rivers will get into in inner tube spare 4, can wash away rubber buffering circle 8 on the axostylus axostyle 7 earlier, and rubber buffering circle 8 can rotate, reduces the impact force of rivers direct impact pipe fitting, has formed the protection to the pipe fitting.

Further, the connecting mechanism 12 comprises a connecting hole 5 and a connecting piece 10, the connecting hole 5 and the connecting piece 10 are matched with each other for use, the connecting hole 5 is formed at two ends of the inner pipe piece 4, the connecting piece 10 and the buffer piece 1 are integrated, and the buffer piece 1 can be disassembled and assembled from the inner pipe piece 4 through matching between the connecting hole 5 and the connecting piece 10, so that the buffer piece 1 can be maintained.

Further, the surface of connecting hole 5 is provided with first connecting screw thread 6, and the surface of connecting piece 10 is provided with the second connecting screw thread 11 that uses of mutually supporting with first connecting screw thread 6, and the connection between connecting hole 5 and the connecting piece 10 is based on mutually supporting of first connecting screw thread 6 and second connecting screw thread 11, during forward rotation, can connecting hole 5 and connecting piece 10 zonulae occludens, during reverse rotation, can separate connecting hole 5 and connecting piece 10.

The working principle is as follows: when in use, the buffer member 1 is matched with the connecting hole 5 in the inner pipe member 4 through the connecting piece 10, then the buffer member 1 is rotated in the forward direction, the buffer member 1 can be fixed on the inner pipe member 4 under the action of the first connecting thread 6 and the second connecting thread 11, then when water flows through the pipe member, the rubber buffer ring 8 on the shaft rod 7 in the buffer mechanism 9 can be firstly impacted, the rubber buffer ring 8 can rotate, the impact force of the water flow is reduced, the inner pipe member 4 is protected, then the water flow enters the inner part of the inner pipe member 4, when the inner pipe member 4 is impacted, the spring 3 can be compressed, the spring 3 can generate reverse action force to reduce the impact force of the water flow, so as to further buffer, when the buffer member 1 needs to be maintained, the buffer member 1 can be rotated in the reverse direction, the buffer member 1 can be removed from the inner pipe member 4 under the action of the first connecting thread 6 and the second connecting thread 11 for maintenance, and in the middle of the pipe fitting use, outer pipe fitting 2 forms the protection to interior pipe fitting 4, guarantees that interior pipe fitting 4 can not receive the influence of external factor, makes the life of interior pipe fitting 4 strengthen to the holistic life of pipe fitting has been prolonged.
