Description
Technical field
The utility model relates to a kind of supplemental components, especially a kind of swivel joint.
Background technique
Pneumatic system is comprised of air pressure generator, control unit, executive component and auxiliary element, thereby wherein the transmission of source of the gas need to connect the composition transmission system by tracheae and joint.Pneumatic tool is the executive component of pneumatic system, is connected with source of the gas by tracheae, at present all adopts general quick inserting joint directly to be connected between pneumatic tool and tracheae.Need rotation frequently at some special occasions pneumatic tools, adopt existing joint usually easily to make the tracheae distortion, even knotting, cause endotracheal air-flow freely even not obstructed, affect air tool normal use, can cause tracheae gas leakage when serious, even fracture.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, provide a kind of can atwirl swivel joint into and out of pore.
for achieving the above object, the utility model adopts a kind of swivel joint, comprise body, connecting body, rotating machinery, body connects by rotating machinery with connecting body, rotating machinery comprises rotating shaft and the bearing of hollow, one end of rotating shaft is fixedly installed back-up ring on circumference, form a circle draw-in groove on the other end circumference of rotating shaft, rotating shaft is arranged on bearing centre, bearing is fixed on inner body wall, body arranges respectively bearing support and bearing cap in the both ends of the surface of bearing, form the cavity of an annular between bearing support and bearing inwardly, back-up ring in rotating shaft is arranged in cavity, body consists of rotation by bearing and rotating shaft and coordinates, be provided with fastening piece on connecting body, fastening piece is stuck in draw-in groove.
The beneficial effects of the utility model are to adopt body and rotating shaft to be rotationally connected, this physical efficiency is rotated in rotating shaft, realized spinfunction, can be arranged on 360 ° of equipment that rotate arbitrarily, have shockproof when High Rotation Speed, noise free, without advantages such as leakage, long service life, equipment operation is got up more flexible.
The fastening piece that the utility model further is set on described connecting body is interior hexagonal stopping screw.Interior hexagonal stopping screw can be riveted tightly in draw-in groove easily, also can unclamp screw, makes body and connecting body separately, and is easy to use.
The utility model further is set to described swivel joint and comprises plastic casing, air pipe sleeve, and plastic casing one end is sealedly connected on connecting body, and the air pipe sleeve sealing is arranged in the plastic casing the other end.
