Description

A kind of effective nut connector that connects of conveniently refuting

Technical field:

The utility model relates to a kind of pipe joint.

Background technique:

The existing effective nut connector that connects of conveniently refuting is to be chewed by T shape water, the nut that cross-under is chewed at T shape water constitutes, T shape water is chewed and is fixedly connected on the flexible pipe, to have the externally threaded water that matches with nut inner thread during use chews in the nut that spins into, to chew end face close mutually with having the externally threaded water that matches with nut inner thread to make T shape water chew end face, push the seal washer between both ends of the surface simultaneously, thereby just both ends of the surface are tightly connected together, make with T shape water to chew, to have and chew two flexible pipe that are connected with the externally threaded water that nut inner thread matches or flexible pipe couples together with watering device with water supply stopcock or flexible pipe.This kind conveniently refute the effective nut connector that connects since nut only cross-under chew at T shape water, like this, nut just is easy to chew from T shape water and is slipped on the flexible pipe, and then drops out from flexible pipe, accommodates and refutes depositing, using and bring very big inconvenience of the pipe that connects.

Summary of the invention:

Goal of the invention of the present utility model is to provide a kind of to be deposited, easy to use, nut is not easy from what refute conveniently that the pipe that connects falls down conveniently to refute the effective nut connector that connects.

The utility model is to realize like this, mainly water on the flexible pipe is chewed by being fixedly connected on, the nut of cross-under on water is chewed constitutes, the connection termination that water is chewed is provided with annular recess, and the end of the nut of corresponding annular recess is provided with snap ring, and snap ring rotates and is arranged in the annular recess.Because the snap ring of nut above it is positioned in the annular recess that water chews, like this, nut just can not be chewed and flexible pipe moves axially along water, prevent nut from water chew, flexible pipe falls down.

Here, the material that water is chewed is copper pipe or alloy aluminum pipe, and the annular recess that water is chewed is chewed the extruding bulge loop on the sidewall and is positioned at water by water and chews the folded turnover ring of end face and form.Adopt copper pipe or alloy aluminum pipe, because copper pipe or alloy aluminum pipe have the good ductility energy, just can chew by extrusion process and to process the extruding bulge loop on the sidewall at water, then, snap ring on the nut is leaned against on the extruding bulge loop, adopting folded turnover technology just tube end outwards can be overturn 90 ° becomes the folded turnover ring, makes snap ring be positioned at extruding bulge loop and folded turnover interannular.

The utility model compared with the prior art, have deposit, easy to use, nut is not easy from conveniently refuting the advantage that the pipe that connects falls down.

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 mainly constitutes by being fixedly connected on the nut 3 that water on the flexible pipe 1 chews 2, cross-under is chewed on 2 at water, water is chewed 2 connection termination and is provided with annular recess 4, and the end of the nut 3 of corresponding annular recess 4 is provided with snap ring 5, and snap ring 5 rotates and is arranged in the annular recess 4.It is copper pipe or alloy aluminum pipe that water is chewed 2 material, and water is chewed annular recess 4 on 2 and chewed the extruding bulge loop 6 on 2 sidewalls by water and be positioned at water and chew the folded turnover ring 7 of 2 end faces and form.

Here, flexible pipe 1 is socketed in water and chews on 2, and flexible pipe 1 arranged outside has sleeve pipe 8, and sleeve pipe 8 tube wall concave-convex surfaces, water are chewed 2 the external diameter internal diameter greater than the flexible pipe 1a that has sleeve pipe 8, and flexible pipe 1a sealing and fixing chews 2 and 8 of sleeve pipes at water.It is to strut pipe that water chews 2, strutting pipe 2 is to form like this, the flexible pipe 1a that will be socketed with sleeve pipe 8 earlier is socketed in external diameter and chews than the little water of flexible pipe 1a internal diameter on 1 the copper pipe or Al-alloy pipe, with instrument copper pipe or Al-alloy pipe external diameter are enlarged to become then and strut pipe 2, make the internal diameter of its external diameter, the tube wall of flexible pipe 1a is sandwiched in strut 8 of pipe 2 and sleeve pipes greater than flexible pipe 1a.Be subjected to the influence of sleeve pipe 8, strut also concave-convex surface of pipe 2 tube walls, thereby prevent that flexible pipe 1 from splitting away off from strutting pipe 2.The concave-convex grain of sleeve pipe 8 tube walls is ripples.

Claims (7)
