Abstract

The utility model discloses a kind of oil circuit connecting tube, described oil circuit connecting tube comprises polyfluortetraethylene pipe and is socketed in the steel pipe at polyfluortetraethylene pipe two ends, goes back spacer sleeve and be connected to a plurality of reinforcing rings on the polyfluortetraethylene pipe body between described steel pipe; Described reinforcing ring and steel pipe are all combined closely with polyfluortetraethylene pipe.By by the exposed elasticity that can improve whole body of teflon tubular portion, the setting by reinforcing ring can improve the intensity of exposed part body again.The elasticity that can improve body like this can guarantee the rigidity of body again.

Description

A kind of oil circuit connecting tube
Technical field
The utility model relates to a kind of oil circuit connecting tube.
Background technique
As everyone knows, existing automobile oil-way connection pipe fitting is steel part, and one end is connected the other end and is connected with output unit with input device.Because automobile work is running state, between input device and output unit, can misplace by occurrence positions, and steel part deformability is poor, can cause in the course of time oil-way pipe distortion even to be broken.It is better that prior art is badly in need of a kind of elasticity, the oil circuit connecting tube that intensity is higher.
Model utility content
The purpose of this utility model is to overcome the defect existing in prior art, provides a kind of elasticity better, the oil circuit connecting tube that intensity is higher.
For achieving the above object, the technical solution of the utility model has been to provide a kind of oil circuit connecting tube, described oil circuit connecting tube comprises polyfluortetraethylene pipe and is socketed in the steel pipe at polyfluortetraethylene pipe two ends, goes back spacer sleeve and be connected to a plurality of reinforcing rings on the polyfluortetraethylene pipe body between described steel pipe; Described reinforcing ring and steel pipe are all combined closely with polyfluortetraethylene pipe.By by the exposed elasticity that can improve whole body of teflon tubular portion, the setting by reinforcing ring can improve the intensity of exposed part body again.The elasticity that can improve body like this can guarantee the rigidity of body again.
As preferably, the polyfluortetraethylene pipe between described reinforcing ring is bellows, and described bellows length is 0.3 ~ 0.8cm, and described reinforcing ring length is 2 ~ 4 times of bellows length.Such design is the further optimization to scheme.
As preferably, the outside coated one deck asbestos braid of described reinforcing ring and bellows, described asbestos braid external diameter is identical with outer diameter of steel pipes, and described reinforcing ring is aluminium ring.Because oil pipe operate outside ambient temperature is all higher in many cases, the asbestos braid heat insulation effect of setting fire of can making a draft.
As preferably, described outer surface of steel tube is provided with burr, and described steel pipe and the establishment of asbestos braid external overall have steel wire establishment belt.Such structure contributes to further to improve the intensity of body, is also a kind of protection to body simultaneously.
Advantage of the present utility model and beneficial effect are: by by the exposed elasticity that can improve whole body of teflon tubular portion, the setting by reinforcing ring can improve the intensity of exposed part body again.The elasticity that can improve body like this can guarantee the rigidity of body again.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, polyfluortetraethylene pipe; 2, steel pipe; 3, reinforcing ring; 4, bellows; 5, asbestos braid; 6, steel wire establishment belt.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, a kind of oil circuit connecting tube, described oil circuit connecting tube comprises polyfluortetraethylene pipe 1 and is socketed in the steel pipe 2 at polyfluortetraethylene pipe 1 two ends, goes back spacer sleeve and be connected to a plurality of reinforcing rings 3 on polyfluortetraethylene pipe 1 body between described steel pipe 2; Described reinforcing ring 3 is all combined closely with polyfluortetraethylene pipe 1 with steel pipe 2.
Polyfluortetraethylene pipe 1 between described reinforcing ring 3 is bellows 4, and described bellows 4 length are 0.3 ~ 0.8cm, and described reinforcing ring 3 length are 2 ~ 4 times of bellows 4 length.
Described reinforcing ring 3 and the outside coated one deck asbestos braid 5 of bellows 4, described asbestos braid 5 external diameters are identical with steel pipe 2 external diameters, and described reinforcing ring 3 is aluminium ring.
Described steel pipe 2 outer surfaces are provided with burr, and described steel pipe 2 and the 5 external overall establishments of asbestos braid have steel wire establishment belt 6.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing from the front lower of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
