Abstract
The invention relates to a cutting sleeve-type pipe joint which comprises a hollow joint body and a connecting nut which is internally provided with a conical surface, a pipe is arranged in the hollow part between the joint body and the connecting nut in a penetrating way, a cutting sleeve is arranged between the pipe and the joint body as well as the connecting nut, and the thickness of the front end of the cutting sleeve is larger than 10 percent to 25 percent of the thickness of a cutting edge. In the cutting sleeve-type pipe joint, as the thickness of the front end of the cutting sleeve is larger than 10 percent to 25 percent of the thickness of the cutting edge, the sealed length between the front end of the cutting sleeve and the joint body is improved, and obvious stopping feeling exists in the installation operation; therefore, the cutting sleeve-type pipe joint is characterized by good tightening feeling and strong anti-vibration capability.
Description
Technical field
The invention belongs to engineering machinery field, employed Bite type fittings when being specifically related to a kind of connection oil pipe and tracheae pipeline.
Background technique
In automobile, boats and ships and engineering mechanical device, there be being connected of many oil pipes and tracheae.Adopt fittings body and a nut of a hollow mostly, pipe is set in the middle vacancy of fittings body and nut, between pipe and fittings body, nut, also has cutting ferrule, when utilizing nut and fittings body to screw to the extruding force of cutting ferrule, cutting ferrule is deformed, and cutting ferrule tip side incision pipe plays effect fixing and sealing.The single-blade cutting ferrule has characteristics such as incision property is good, and torque force is low, but the single-blade cutting ferrule of prior art, because the thickness of cutting ferrule front end is less than cutting edge thickness, there is defectives such as tightening sense difference and freedom from vibration difference in pipe joint.
Summary of the invention
There is defectives such as tightening sense difference and freedom from vibration difference in the Bite type fittings that the objective of the invention is to solve existing single-blade cutting ferrule, design a kind of tighten sense well, Bite type fittings that the anti-vibration ability is strong.
The object of the present invention is achieved like this: Bite type fittings of the present invention, it comprises fittings body, the attaching nut of hollow, the conical surface is arranged in the attaching nut, pipe is set in vacancy among fittings body and the attaching nut, also have a cutting ferrule between pipe and fittings body, attaching nut, the nose thickness of cutting ferrule is greater than cutting edge thickness 10%-25%.
Above-mentioned Bite type fittings is because the nose thickness of cutting ferrule is greater than the 10%-25% of cutting edge thickness.Improved the seal length of cutting ferrule front end and fittings body, had in the fitting operation and significantly end sense.Therefore, have the sense of tightening well, characteristics that the anti-vibration ability is strong.
Description of drawings
Fig. 1 is the mounting structure schematic representation of Bite type fittings of the present invention.
Fig. 2 is the structural representation of the cutting ferrule of Bite type fittings of the present invention.
Embodiment
The invention will be further described by embodiment below in conjunction with accompanying drawing:
As depicted in figs. 1 and 2, Bite type fittings of the present invention, it comprises fittings body 1, the attaching nut 2 of hollow, in the attaching nut 2 conical surface is arranged, pipe 4 is set in vacancy among fittings body 1 and the attaching nut 2, also have a cutting ferrule 3 at pipe 4 and fittings body 1,2 of attaching nuts, front end 5 thickness of cutting ferrule 3 are greater than cutting edge thickness 20%.
Claims (1)
1, a kind of Bite type fittings, it comprises fittings body (1), the attaching nut (2) of hollow, the attaching nut has the conical surface in (2), pipe (4) is set in vacancy among fittings body (1) and the attaching nut (2), also have a cutting ferrule (3) between pipe (4) and fittings body (1), attaching nut (2), front end (5) thickness that it is characterized in that above-mentioned cutting ferrule (3) is greater than cutting edge thickness (6) 10%-25%.
