Description
Technical field
The utility model is about a kind of connection flexible pipe, and is special relevant with a kind of joint structure of the flexible pipe that spins.
Background technique
The flexible pipe more application connects in the water route of tap, sanitary equipment, shower; It is relatively-stationary structure that general flexible pipe connects between back connecting end and the external piece; Flexible pipe is easily because reverse or twine and cause jointing stress to concentrate and break in the use, influences working life and external form attractive in appearance of flexible pipe.For overcoming aforementioned disadvantages, industry transfers to use a kind of spin flexible pipe, and wherein a kind of structure is as shown in Figure 1; Mainly be made up of flexible pipe 1 ', joint 2 ', connecting sleeve 3 ' and attaching nut 4 ', joint 2 ' one end is fixedly connected with flexible pipe 1 ', and the other end protrusion flexible pipe is outer to form rotating the connection with connecting sleeve 3 '; Be connected with the external piece screw lock through attaching nut 4 ' at last; Utilize this structure, flexible pipe 1 ' utilize joint 2 ' and connecting sleeve 3 ' can relative to rotate and eliminate reversing and twining of taking place in the use, protection flexible pipe; But said structure is because joint 2 ' is that face contacts with connecting sleeve 3 ' fitting surface; Joint 2 ' need overcome bigger frictional force when relatively rotating with connecting sleeve 3 ', has some setbacks during rotation, and it is desirable that the actual effect that eliminates stress does not become.
The model utility content
Therefore, the utility model provides a kind of spin hose coupling structure to above-mentioned deficiency, can effectively solve reversing and the winding problem of taking place in the flexible pipe use, and then the protection flexible pipe, prolongs the working life of flexible pipe.
The utility model is adopted following technical scheme to reach above-mentioned purpose: a kind of spin hose coupling structure; Mainly be made up of flexible pipe, joint, adapter sleeve and attaching nut, flexible pipe is a hollow tube body, and an end of joint is fixedlyed connected with flexible pipe; The other end is connected with adapter sleeve; What the attaching nut became flexible is nested with in the outside of flexible pipe, joint and adapter sleeve, and wherein moulding two ring grooves in interval on the outer wall of this joint other end supply to be provided with sealing ring and " C " type ring respectively; This adapter sleeve is set on the other end of joint, forms rotating the connection with joint.
The middle part of this connecting sleeve is provided with up big and down small ladder trepanning, passes through chamfered transition between this size trepanning.
Outside the part convex hole groove, its external diameter is littler than the big trepanning internal diameter of connecting sleeve, and was bigger than little trepanning internal diameter when " C " type of being somebody's turn to do was located on the joint ring groove.
Also be provided with limited step on the outer wall of this connecting sleeve.
This attaching nut's inwall is provided with boss, and the end is provided with the internal thread that is connected with external piece.
Adopt said structure, can relatively rotate between the utility model joint and connecting sleeve, and through improving the cooperating structure between joint and the connecting sleeve; Make two member fitting surface area of contact little; Thereby the power of reducing friction, making between flexible pipe and the external piece A can flexible free and relaxed rotation, uses lighter.
Description of drawings
Fig. 1 is for commonly using the spin hose construction;
Fig. 2 is the STRUCTURE DECOMPOSITION figure of the utility model;
Fig. 3 is the structure sectional view of the utility model.
Embodiment
The utility model spin hose coupling structure is like Fig. 2, shown in 3; Mainly form by flexible pipe 1, joint 2, connecting sleeve 3 and attaching nut 4; Flexible pipe 1 is a hollow tube body, and an end 21 of joint 2 stretches in the flexible pipe and is fixedly connected with flexible pipe, cooperates with connecting sleeve 3 outside the other end 22 protrusion flexible pipes; The middle part of joint 2 is the through hole 23 that runs through two ends; Moulding two ring grooves 24,25 at interval on the outer wall of this joint the other end 22 supply respectively seal ring 5 and " C " type ring 6 are set, when being located at ring groove 25 outside the part convex hole groove; Connecting sleeve 3 is set on the other end 22 of joint protrusion flexible pipe; Form rotating connections with joint 2, the middle part of this connecting sleeve 3 is provided with the up big and down small ladder trepanning 31,32 that cooperates with joint, this size trepanning 31, passes through inclined-plane 33 transition between 32; The aperture of this big trepanning 31 is greater than the external diameter of joint 2 the other ends 22; The external diameter of 32 matched junction the other ends 22 of little trepanning, joint 2 utilize the inclined-plane 33 in " C " type ring 6 and the connecting sleeve trepanning on the joint the other end to cooperate to realize self-locking when being connected with connecting sleeve 3, the external diameter of this " C " type ring 6 is littler than the big trepanning of connecting sleeve 31; Bigger than little trepanning 32, also be provided with limited step 34 on the outer wall of connecting sleeve 3 in addition; Said attaching nut 4 is loosening is nested with the outside at flexible pipe 1, joint 2 and connecting sleeve 3; These attaching nut's 4 inwalls are provided with boss 41; The end is provided with the internal thread 42 that is connected with external piece; Flexible pipe is connected with the external piece screw lock through attaching nut 4, and the boss 41 that connects back attaching nut's 4 inwalls pushes up the limited step 34 that supports with the connecting sleeve outer wall.
Adopt said structure, 3 of the utility model joint 2 and connecting sleeves can relatively rotate, and through improving the cooperating structure between joint and the connecting sleeve; Make two member fitting surface area of contact little; Thereby the power of reducing friction, making between flexible pipe and the external piece A can flexible free and relaxed rotation, uses lighter.
