In order to achieve the above object, the utility model is achieved by the following technical programs:
A kind of connection structure of hard tube and cable, including fitting body and hard tube, the hard tube are socketed in cable outer surface, institute
It states fitting body both ends and is equipped with external screw thread, and bosom is provided with step surface, the hard tube is located at fitting body interior step face
Left side, the fitting body left outer surface is connected with metal end formula nut by screw thread, and the metal end formula nut is living
Dynamic to be linked in hard tube outer surface, the metal end formula nut inner cavity is provided with end formula joint sealing circle, the end formula joint sealing
Circle is located at hard tube outer surface；Outer surface is connected with round metal nut, the round metal by screw thread on the right side of the fitting body
Nut is movably combined in cable outer surface, and round metal nut inner cavity is provided with jacket type sealing element, the jacket type sealing
Part is located at the right side in fitting body interior step face.
Preferably, the end formula joint sealing circle is close to the tapered structure in the side of fitting body.
Preferably, the metal end formula nut and round metal nut outer surface are hex surface structure, the metal end formula
Nut uses arc transition, and the round metal nut is that 60 degree of angles are smoothly connected.
Preferably, nitrile rubber material can be used in the end formula joint sealing circle, and silicon can be used in the jacket type sealing element
Rubber material.
The utility model provides the connection structure of a kind of hard tube and cable.Have following the utility model has the advantages that by metal
Formula joint sealing circle in end is set in the formula nut of end, and the tapered end of end formula joint sealing circle is made to be directed toward fitting body, to work as metal
When end formula nut is screwed in one end of fitting body, the tapered end of meeting pressed end formula joint sealing circle forces it to be deformed inward extruding
Hard tube makes steel pipe be easily installed connection to play the role of locking to hard tube；By the way that jacket type sealing element is arranged, to work as
When round metal nut screws in fitting body, squeezing action can be generated to jacket type sealing element, force its deformation inwardly tightening, and then right
Cable plays the role of locking and sealing.
Detailed description of the invention
It, below will be to description of the prior art in order to illustrate more clearly of the utility model or technical solution in the prior art
Needed in attached drawing be briefly described.
The structural schematic diagram of Fig. 1 the utility model；
Figure label explanation:
1, fitting body；2, hard tube；3, metal end formula nut；4, formula joint sealing circle is held；5, round metal nut；6, jacket type
Sealing element；7, cable.
Specific embodiment
To keep the purpose of this utility model, technical solution and advantage clearer, implement below in conjunction with the utility model
Attached drawing in example, is clearly and completely described the technical solution in the utility model.
As shown in Figure 1, the connection structure of a kind of hard tube and cable, including fitting body 1 and hard tube 2, hard tube 2 are socketed in cable
7 outer surfaces, 1 both ends of fitting body are equipped with external screw thread, and its bosom is provided with step surface, and hard tube 2 is located inside fitting body 1
The left side of step surface, 1 left end outer surface of fitting body are connected with metal end formula nut 3 by screw thread, and metal end formula nut 3 is living
Dynamic to be connected to 2 outer surface of hard tube, 3 inner cavity of metal end formula nut is provided with end formula joint sealing circle 4, holds 4, formula joint sealing circle
In 2 outer surface of hard tube；1 right end outer surface of fitting body is connected with round metal nut 5,5 activity of round metal nut by screw thread
It is connected to 7 outer surface of cable, 5 inner cavity of round metal nut is provided with jacket type sealing element 6, and jacket type sealing element 6 is located at fitting body 1
The right side in interior step face.
End formula joint sealing circle 4 is close to the tapered structure in the side of fitting body 1.
Metal end formula nut 3 and 5 outer surface of round metal nut are hex surface structure, and metal end formula nut 3 uses circular arc
Transition, round metal nut 5 are that 60 degree of angles are smoothly connected.
Nitrile rubber material can be used in end formula joint sealing circle 4, and silicone rubber material can be used in jacket type sealing element.
Working principle is as follows:
By the way that fitting body 1 and hard tube 2 are socketed in 7 outer surface of cable, and hard tube 2 is mounted on 1 interior step of fitting body
