Description

A kind of hose coupling
Technical field
It is especially that a kind of hose for connecting hoses on hydraulic device connects the utility model relates to a kind of connector Head.
Background technique
Current hose coupling generally comprises hollow connector rod core and covers the nut in connector rod core lower part, connector rod Core is connected on the pipeline in hydraulic device by nut, and after tightening nut, connector rod core one end end face can be with pipeline one end end Face is close to, and generates flexible deformation at abutting to be sealed, however, since connector rod core and pipeline are hollow structure, Its contact area is very small, only an annular facet, therefore, the sealing of above-mentioned hose coupling in actual use Effect is not highly desirable, and hose is not connected firmly, easy to fall off.
Utility model content
The technical problem to be solved by the present invention is to provide one kind to enable hose conveniently, securely, and cracky does not leak Piping connection and the preferable hose coupling of sealing effect in ground and hydraulic device.
In order to solve the above-mentioned technical problem, the utility model provides a kind of hose coupling, including hollow joint tube core, institute The one end for stating hollow joint tube core is hollow conical pipe, and the smaller diameter end of the hollow conical pipe is equipped with the flange of protrusion, institute The other end for stating flange is connector, and the hollow joint tube core is integrally formed, and is arranged on the outside of the hollow conical pipe point Duan Jia, the sectional splint then push the sectional splint to the sky in the fixed hose of smaller diameter end of the hollow conical pipe The larger diameter end of heart conical pipe makes hose and connector fixation and sealing effect is good to compress hose.
Further, the internal diameter of the sectional splint is greater than the outer diameter of the smaller diameter end of the hollow conical pipe and is less than described The outer diameter of the larger diameter end of hollow conical pipe will not take off while being easily installed the sectional splint from the hollow conical pipe It falls.
Further, the sectional splint includes first segment folder and second segment folder, and the first segment folder and second segment folder pass through Screw closure is easily installed and locks, and the end of the first segment folder and second segment folder is additionally provided with the screw thread of the second screw of installation Hole facilitates the larger diameter end that the sectional splint is pushed to the hollow conical pipe.
Further, the outer surface of the hollow conical pipe is equipped with anti-skidding dimpled grain, increases hose and the hollow conical pipe The friction of outer surface, prevents hose from slipping.
Further, the hollow joint tube core material is copper pipe, is simple to manufacture and cost is relatively low.
The beneficial effect of the hose coupling of the utility model compared with prior art is: structure is simple and convenient to operate and energy Enough make hose good with connector fixation, not cracky and sealing effect.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model structure;
Fig. 2 is the utility model overall structure diagram.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art The utility model may be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
As depicted in figs. 1 and 2, a kind of hose coupling, including hollow joint tube core 1, one end of the hollow joint tube core 1 For hollow conical pipe 11, hose 3 is set on the hollow conical pipe 11, and the smaller diameter end of the hollow conical pipe 11 is equipped with convex The other end of flange 12 out, flange 12 described in the end abutment of hose 3, the flange 12 is connector 13, is used for Other pipelines are connected, the hollow joint tube core 1 is integrally formed, and guarantees the intensity and leakproofness of the hollow joint tube core 1, institute The outside for stating hollow conical pipe 11 is arranged sectional splint 2, for fixing hose 3, when work, is first set in the sectional splint 2 Smaller diameter end and locking close to the hollow conical pipe 11, then the sectional splint 2 pushes the big of the hollow conical pipe 11 to Diameter end, hose 3 is increasing by the extruding force between the hollow conical pipe 11 and sectional splint 2, to make hose 3 and hose Being completely embedded between 3 connectors and securely.
As the further technical solution of the utility model, to ensure that the sectional splint 2 is supported with the hollow joint tube core 1 It connects securely and will not slip, the internal diameter of the sectional splint 2 is greater than the outer diameter of the smaller diameter end of the hollow conical pipe 11 and is less than The outer diameter of the larger diameter end of the hollow conical pipe 11, to facilitate the installation sectional splint 2 and fixed locking hose 3.
As the further technical solution of the utility model, the sectional splint 2 includes that first segment folder 21 and second segment press from both sides 22, The first segment folder 21 and second segment folder 22 are sealed by the first screw 23, and two-part sectional splint 2 is easily installed and locks, simultaneously For convenience of the larger diameter end that the sectional splint 2 is pushed to the hollow conical pipe 11, the first segment folder 21 and second segment folder 22 End be additionally provided with the threaded hole of the second screw 24 of installation, the sectional splint 2 is set in close to the hollow conical pipe 11 Smaller diameter end and by the first screw 23 lock after, second screw 24 is screwed out in the air from screw thread, makes the second screw 24 Flange 12 described in end abutment, the second screw 24 abutted during back-out with the flange 12 it is even closer, from And push the sectional splint 2 mobile to the larger diameter end of the hollow conical pipe 11, until second screw 24 can not continue It screws out.
As the further technical solution of the utility model, the outer surface of the hollow conical pipe 11 is equipped with anti-skidding dimpled grain, It will not be slipped after clamping hose 3 by the sectional splint 2 and hollow conical pipe 11.
As the further technical solution of the utility model, 1 material of hollow joint tube core be copper pipe, it is easily manufactured and Cost is relatively low.
Embodiment described above is only preferred embodiments for fully illustrating the utility model, the utility model Protection scope it is without being limited thereto.Those skilled in the art made equivalent substitute or change on the basis of the utility model It changes, both is within the protection scope of the present invention.The protection scope of the utility model is subject to claims.
