Water feeding connector device for passenger car

Abstract

The invention relates to a water feeding connector device for a passenger car. The water feeding connector device for the passenger car comprises a tube, a rubber sleeve, a guiding barrel, a piston and water tube connector, wherein the tube is hollow, and openings are formed in two ends of the tube; the water tube connector is sealed and is detachably mounted at one end of the tube; the rubber sleeve is hollow, openings are formed in two ends of the rubber sleeve, the rubber sleeve is mounted at the other end of the tube in a sealed manner, and a compaction cavity is formed between the side wall of the rubber sleeve and the inner wall of the tube; the guiding barrel is a barrel of which the two ends are provided with openings, the guiding barrel is inserted in the tube, the inside of the guiding barrel is divided into a water inlet cavity and a piston cavity by a partition, the water inlet cavity and the piston cavity are independent from each other and are arranged coaxially, an exhaust hole is formed in the bottom wall of the piston cavity, water inlet holes are formed in the wall of the water inlet cavity, and an opening end of the water inlet cavity communicates with the watertube connector; the piston is axially slidably arranged in the piston cavity; a guiding tube is arranged at the end, which is close to the rubber sleeve, of the piston; the end, which is away from thepiston, of the guiding tube extends into the other end of the rubber sleeve; and a plurality of through holes are uniformly distributed in the side wall of the guiding tube. The water feeding connector device for the passenger car has the advantages that the device is convenient to assemble and disassemble, water feeding self-locking and automatic disassembling after water feeding is finished canbe realized, and thus, the labor intensity is relieved.

Description

technical field [0001] The invention relates to the technical field of locomotive accessories, in particular to a passenger car water supply joint device. Background technique [0002] Currently, each train has a dedicated water injection port. The process of adding water to the train is often done manually, usually through the connection of the water pipe joint and the water injection port to realize the water injection, but the disassembly and assembly between the traditional water pipe joint and the water injection port is more troublesome, and there are some defects in the sealing performance, resulting in The work efficiency of the train crew is low, the labor intensity is high, and it is very likely to cause a waste of water resources. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a passenger car water supply joint device, which effectively overcomes the defects of the prior art. [0004] The technical ...
