Description
ROTARY PIPE CONNECTOR
BACKGROUND OF THE INVENTION
(a) Field of the Invention:
The present invention relates to a pipe connector, and more particularly to a rotary pipe connector for securing a pipe to a liquid reservoir fitting for permitting the pipe to be rotated through 360° relative to the liquid reservoir fitting.
(b) Description of the Prior Art:
Regular rubber hoses are intensively used in oil and chemical delivery vehicles, pumpers, gasoline pumps, movable water pumps, etc. for delivering oil, liquid chemicals, gasoline or water. When connecting a rubber hose to a vehicle, pumper, gasoline pump or water pump. a pipe connector shall be used.
When a pipe connector is fastened to a rubber hose and installed in I~ a vehicle, pumper, gasoline pump or water pump, the rubber hose cannot be freely rotated relative to the vehicle, pumper, gasoline pump or water pump. If the rubber hose is twisted, the hose body of the rubber hose is forced to deform, causing the liquid delivery efficiency to be affected (see Figure 1). Further, frequently twisting the rubber hose may cause the hose body to break. causing a leakage. It is dangerous when a liquid chemical leaks out through a crack in the rubber hose of a chemical delivery vehicle.
SUMMARY OF THE INVENTION
The present invention provides a rotary pipe connector for securing a pipe to a liquid reservoir fitting for permitting the pipe to be rotated through 360° relative to the liquid reservoir fitting.
A rotary pipe connector according to the preferred embodiment of the present invention is comprised of a first connector member fastened to the pipe. and a second connector member fastened to the machine fitting and inserted into a center through hole at the first connector member and stopped at an inside annular flange inside the first connector member. A plurality of steel balls are inserted through a radial screw hole at the first connector member into matched annular ball grooves between the inside wall of the first connector member and the outside wall of the second connector member to secure the second connector member to the inside of the first connector member, for permitting the second connector member to be rotated with the connected pipe in the first connector member.
