Abstract

The utility model provides a pipe convenient for connection, comprising a hose, a nut which is arranged at an end of the hose and is provided with a T-shaped water nozzle, as well as a water nozzle having an outer thread matched with an inner thread of the nut. The pipe is characterized in that the T-shaped water nozzle and the water nozzle having the outer thread matched with the inner thread of the nut are made of copper or aluminum; the hose covers the T-shaped water nozzle and the water nozzle having the outer thread matched with the inner thread of the nut; the hose is sleeved with a casing pipe; the wall of the casing pipe is in a concave-convex shape; the outer diameter of the T-shaped water nozzle and the water nozzle having the outer thread matched with the inner thread of the nut is greater than the inner diameter of the hose; the distance between the T-shaped water nozzle and the water nozzle having the outer thread matched with the inner thread of the nut and the inner wall of the casing pipe is less than the thickness of the wall of the hose. Compared with the prior art, the pipe has the advantages that the hose is steadily sealed and fixed on the T-shaped water nozzle and the water nozzle with stable sealing-fixing quality.

Description

A kind of pipe that connects of conveniently refuting

Technical field:

The utility model relates to a kind of pipe fitting.

Background technique:

Existing conveniently refute the pipe that connects by flexible pipe, be arranged on having nut that T shape water chews, having the externally threaded water that matches with nut inner thread and chew and constitute of the sub-two ends of flexible pipe, T shape Shui Zui, water are chewed the two ends that are fixed on flexible pipe by locking hoop, and the end face that T shape Shui Zui is connected with Shui Zui is provided with seal washer.During use, to have externally threaded water chews in the nut on another flexible pipe into of spinning, making T shape water chew end face and water, to chew end face close mutually, push the seal washer between both ends of the surface simultaneously, thereby just both ends of the surface are tightly connected together, and two flexible pipe or flexible pipe and water supply stopcock or flexible pipe are coupled together with watering device.This kind conveniently refuted the pipe that connects and chewed owing to its T shape water, water is chewed the two ends that only are fixed on flexible pipe by the locking hoop that has screwing mechanism, thereby and locking hoop is by screwing mechanism the diameter of locking hoop to be received little hose diameter is shunk to make it be fixed on T shape water to chew, water is chewed, like this, the power that locking hoop acts on the flexible pipe is uneven, be not easy to guarantee flexible pipe to be subjected to uniform pressure and sealing and fixing is chewed at T shape water, water is chewed, be subjected to the restriction of the quality of flexible pipe, the contraction of pipe diameter is very difficult, like this, just making flexible pipe be not easy sealing and fixing chews at T shape water, water is chewed, it is chewed from T shape water easily, water is chewed and is come off, and, screwing mechanism on the locking hoop had both influenced the use of pipe as an obstacle, and simultaneously, flexible pipe is fixed on T shape water and chews, the quality that water is chewed is subjected to the influence of operator and screwing mechanism quality very big.

Summary of the invention:

Goal of the invention of the present utility model is to provide a kind of flexible pipe chew at T shape Shui Zui, water and stay-in-grade pipe that connects of conveniently refuting sealing and fixing of sealing and fixing firmly.

The utility model is to realize like this, comprise flexible pipe, be arranged on the nut that T shape water is chewed that has of the sub-termination of flexible pipe, having the externally threaded water that matches with nut inner thread chews, its specialization is that T shape water chews, having the material that the externally threaded water that matches with nut inner thread chews is copper or aluminium, tube socket is chewed at T shape water, having the externally threaded water that matches with nut inner thread chews, be socketed with sleeve pipe in the flexible pipe outside, cover tube wall concave-convex surface, T shape water is chewed, it is bigger than the internal diameter of flexible pipe to have the external diameter that the externally threaded water that matches with nut inner thread chews, and T shape water is chewed, have and externally threaded water that nut inner thread matches is chewed and internal surface of sleeve pipe between distance less than the thickness of flexible pipe tube wall.Make for convenience, the pipe that the externally threaded water that matches with nut inner thread chews with the flexible pipe connecting part is chewed, had to T shape water is to strut pipe.Because the material that T shape Shui Zui, water are chewed is copper or aluminium, like this, can earlier the tube socket that is socketed with sleeve pipe be chewed at external diameter T shape Shui Zui, the water littler than inner diameter, the external diameter of T shape Shui Zui, water being chewed with instrument enlarges to become and struts pipe then, make the internal diameter of its external diameter greater than flexible pipe, make the tube wall of flexible pipe be sandwiched in T shape Shui Zui, water is chewed and sleeve pipe between.The expansion of inner diameter is relatively easy, and employing instrument external diameter that T shape Shui Zui, water are chewed to enlarge the sealing load that flexible pipe is subjected to everywhere even, assurance flexible pipe sealing and fixing is chewed at T shape Shui Zui, water, adopt the sleeve pipe of tube wall concave-convex surface, when the external diameter of T shape Shui Zui, water being chewed with instrument enlarges, T shape Shui Zui, Shui Zui are subjected to the influence of sleeve pipe, and its tube wall is concave-convex surface also, thereby prevent that flexible pipe from chewing and splitting away off from T shape Shui Zui, water.

The utility model compared with the prior art, have flexible pipe firmly sealing and fixing at T shape Shui Zui, water chew and stay-in-grade advantage sealing and fixing.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Embodiment:

Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:

As shown in the figure, the utility model comprises flexible pipe 1, the T shape water that has that is arranged on flexible pipe 1 termination is chewed 2 nut 3, the water that has the outside thread 5 that matches with nut 3 internal threads chews 4, chew 2 at T shape water, water is chewed 4 and is provided with seal ring 11, its specialization is that T shape water chews 2, it is copper or aluminium that the water that has an outside thread 5 that matches with nut 3 internal threads is chewed 4 material, flexible pipe 1 is socketed in T shape water and chews 2, the water that has the outside thread 5 that matches with nut 3 internal threads is chewed on 4, be socketed with sleeve pipe 6 in flexible pipe 1 outside, sleeve pipe 6 tube wall concave-convex surfaces, T shape water chews 2, it is bigger than the internal diameter of the flexible pipe 1a that has sleeve pipe 6 that the water that has an outside thread 5 that matches with nut 3 internal threads is chewed 4 external diameter, and T shape water chews 2, have and the water of the outside thread 5 that nut 3 internal threads match chew 4 and sleeve pipe 6 inwalls between distance less than the thickness of flexible pipe 1a tube wall.

Make for convenience, the water that T shape water chews 2, have an outside thread 5 that matches with nut 3 internal threads chew 4 with the pipe of flexible pipe connecting part be to strut pipe.

In order to prevent that nut 3 from chewing 2 along T shape water and moving axially, T shape water is chewed 2 and is provided with positioning ring 7, and positioning ring 7 and T shape water are chewed 2 termination 8 and formed annular grooves 9, and nut 3 rotates by the snap ring above it 12 and is arranged in the groove 9.

Make for convenience, the concave-convex grain 10 on the sleeve pipe 6 is a curl.
