Air hose connector for tight-lock coupler

Abstract

The invention discloses an air hose connector for a tight-lock coupler of a vehicle. The air hose connector comprises valve port rubber, a valve head, a pressure spring, a valve body, a sealing pad, a tappet, a tappet spring, a main air hose and an uncoupling pipe, wherein the valve head is provided with a barrel which extends towards the direction of the valve body; the barrel sleeves a valve hole base of the valve body and is in sliding fit with the valve hole base; a sealing ring is arranged between the valve body and the valve hole base of the valve body; the pressure spring sleeves outside the barrel; one end of the pressure spring is propped against the valve head and the other end is propped against the valve body; the rear part of the uncoupling pipe is inserted into an uncoupling pipe hole of the valve body and is in sliding seal fit with the uncoupling pipe hole; an uncoupling pipe spring is arranged in the uncoupling pipe hole; one end of the uncoupling pipe spring is propped against the rear end of the uncoupling pipe and the other end is propped against the valve body wall at the bottom of the uncoupling pipe hole. The air hose connector is simple in structure, high in spare part universality and easy to use and maintain.

Description

technical field [0001] The invention relates to a vehicle pipe connector, in particular to an air pipe connector for realizing the automatic connection of a main air pipe of a closely-connected coupler and an uncoupling air pipe. Background technique [0002] In order to improve the riding comfort of EMUs and subway vehicles and reduce the longitudinal impact of couplers between carriages, close-fitting coupler buffer devices are generally used for the connection of high-speed EMUs and subway vehicles. The close-connected coupler buffer device is divided into fully automatic, semi-automatic and semi-permanent coupler buffer devices. The fully automatic and semi-automatic coupler buffer devices require the connection of the air duct while the mechanical coupler is connected. Leakage. [0003] The air duct connector is mainly used to realize the automatic connection of the main air duct of the airtight coupler and the uncoupling air duct and the automatic locking of the main ...

Problems solved by technology

[0003] The air duct connector is mainly used to realize the automatic connection of the main air duct of the airtight coupler and the uncoupling air duct and the automatic locking of the main air duct. The air duct connectors of the prior art, such as figure 1 As shown, it is mainly composed of valve body 06, valve head 02, tappet 010, gasket 07, pressure spring 04, tappet spring 08, valve port rubber 01, rubber tube 03, main air duct 09, uncoupling tube 011, etc. , the air duct connector can realize the automatic conduction of the main air duct and the uncoupling air duct when the coupler is connected, and the automatic locking of the main air duct when the coupler is unhooked, but the sealing structure inside the main air duct connector is controlled by the rubber tube 03 , The pressure spring 04 and the valve body 06 are extruded together; the sealing structure of the unhooking air pipe connector is composed of two ends of the unhooking pipe 011 extruding each other, the structure is complex, the manufacturing technology is difficult, and the parts are not universal. Inconvenient to maintain
