Technical Field

The invention relates to the technical field of hydraulic product structures, in particular to a rotatable nozzle structure for an airplane.

Background

At present, hydraulic products are widely applied to the field of aviation, however, the connecting nozzle of the hydraulic product is fixed and limited by the installation space of an airplane, so that the pipeline connection of an airplane brake system is difficult, and the product needs to be detached again to adjust the installation position, thereby wasting time.

Disclosure of Invention

The invention aims to: the rotatable adapter nozzle structure for the airplane can effectively solve the problem that a hydraulic product is difficult to connect with an airplane brake system pipeline only by adjusting the position of the adapter nozzle without detaching the product again.

The utility model provides an aircraft is with rotatable coupling nozzle structure, is chewed including the connecting pipe, the one end periphery cover of connecting pipe is equipped with the bearing housing, and the other end is connected on hydraulic pressure oil pipe, the relative both sides in the lower part are chewed to the connecting pipe in the bearing housing have seted up half-circular arc draw-in groove respectively, be equipped with the steel ball in the draw-in groove, the inside circumference of bearing housing downside has seted up the spout that is suitable for the steel ball rolling, the cover is equipped with the connecting cap on the bearing housing, the inside circumference of bearing housing upper portion upwards all seted up the sealing washer standing groove with the inside circumference of connecting cap upside, is equipped with first sealing washer and second sealing washer in the two sealing washer standing grooves respectively, the connecting cap is kept away from the connecting pipe and is chewed one end and is passed through threaded connection on the part casing.

Further, a protection ring for protecting the first sealing ring is arranged in a sealing ring placing groove of the bearing sleeve.

Furthermore, a gasket is sleeved on the periphery between the connecting cap and the part shell.

Furthermore, the connection mode of the bearing sleeve and the connection cap is threaded connection.

Still further, the steel ball can be fixed or movably arranged in the clamping groove.

The invention has the beneficial effects that:

according to the rotatable pipe nozzle structure for the airplane, the pipe nozzle can freely rotate for 360 degrees through the arranged pipe nozzle, the bearing sleeve sleeved on the periphery of the pipe nozzle and the steel ball on the pipe nozzle, frequent disassembly of parts is avoided, and the problem that a hydraulic product is difficult to connect with a pipeline of an airplane brake system is effectively solved.
