Specific embodiment
In order that those skilled in the art more fully understands the technical solution of the utility model, below in conjunction with accompanying drawing pair
The utility model is further detailed.
It is a kind of joint connecting structure that the utility model embodiment is provided referring to shown in Fig. 1 and Fig. 2, it is used to connect
Steel pipe 2 and flexible pipe 1, also bag joint 3, joint 3 include：
Lining core 31, one end of lining core 31 is inserted on flexible pipe 1, it is preferable that using elastic conjunction mode realize lining core 31 with it is soft
The connection of pipe 1, can also use engagement thread certainly；The other end of lining core 31 is the external part for stretching out flexible pipe 1, and external part is circumscribed with
Engaging round platform 32, the effect for engaging round platform 32 is mating connection nut 33, realizes its being fixed with attaching nut 33.
Attaching nut 33, as shown in figure 3, the connection of joint 2 and steel pipe 3 is realized in its effect；One end of attaching nut is provided with
The spacing round platform 34 of inside projection, spacing round platform 34 engages with round platform 32 is engaged；The other end of attaching nut 33 is fixed on steel pipe 3
On, the outer wall of steel pipe 3 is provided with external screw thread, that is to say, that attaching nut 33 is connected on steel pipe 3 by the way that screw thread cooperation is outer, the company of screwing
Connected nut 33, attaching nut 33, to the lateral movement away from flexible pipe, and drives steel pipe 3 and the relative motion of flexible pipe 1 on steel pipe 3.
Attaching nut 33 is fixed on steel pipe 3 by screw thread cooperation, and the connection of flexible pipe 1 and steel pipe 3 is realized with this.
This programme connected nut outside the end of joint 2, its connection with steel pipe 3 is realized by screw thread fit form, connection
It is reliable, it is to avoid when flexible pipe is adjusted, joint 2 disconnects with steel pipe 3, influence normal vehicle operation.Simultaneously external nut is facilitated
Installation of the flexible pipe on steel pipe.
With reference to shown in Fig. 4 and Fig. 5, steel pipe 3 on the side end face for engaging round platform 32 just to offering an annular groove 35；Annular
Rubber ring 35 is installed in groove 35, when flexible pipe is connected with joint and tightens, rubber washer 36 is extruded, and then reach sealing function.
When flexible pipe moves towards adjustment, the circle of rubber blanket 36 will not occur breakage because of being dismounted for multiple times, meanwhile, rubber ring 36 also plays buffering
The effect of joint and steel pipe intermolecular forces.
In this programme, lining core 31 realizes being connected to for the two with flexible pipe 1 using elastic conjunction, in order that lining core 31 with
The cooperation of flexible pipe 1 is tightr, in this programme, as shown in fig. 6, lining core includes column and is located at the engaging circle of column end
Platform 32；Multiple continuous locking slots 37 are provided with along the length direction of column on column, each locking slot is endless groove, ring-type
When groove coordinates, to contract deformation, because flexible pipe is to be inserted into column, thus, the endless groove of column is carried for its both sides
The reaction force of supplying flexible pipe outer wall one, so that it is even closer with the cooperation of flexible pipe.Certainly, can also be in the column of lining core
One layer of sleeve 38 of upper parcel, as shown in Fig. 2 sleeve 38 is made up of elastomeric material, facilitates dismounting of the lining core 31 on flexible pipe 1.
It should be noted that in such scheme, the external diameter for engaging round platform 32 is equal with the internal diameter of attaching nut 33, to ensure
After attaching nut 33 and steel pipe 3 tighten cooperation, lining core 31 determines with the relative position of attaching nut 33.
Some one exemplary embodiments of the present utility model only are described by way of explanation above, undoubtedly, for
One of ordinary skill in the art, in the case of without departing from spirit and scope of the present utility model, can be with a variety of
Mode is modified to described embodiment.Therefore, above-mentioned accompanying drawing and description are inherently illustrative, should not be construed as
Limitation to the utility model claims.
