Direct insertion type train water feeding anti-pulling pipe quick connector

Abstract

The invention relates to the technical field of passenger car water feeding equipment and train water injection nozzle connection, in particular to a direct insertion type passenger train water feeding anti-pulling pipe quick connector which comprises a water jacket and a clamping spring. The water jacket is a cylinder, and the clamping spring comprises an annular hanging part and a plurality of elastic limiting pieces arranged below the annular hanging part; the elastic limiting pieces are uniformly distributed on the circumference of the annular hanging part, and the lower ends of the elastic limiting pieces obliquely extend to the perpendicular bisector of the annular hanging part to form a funnel shape; the clamp spring is hung at the upper end of the water jacket through the annular hanging part; a locking sleeve is further arranged below the clamping spring, and a reset spring is further arranged between the locking sleeve and the water jacket; and the upper end of the water jacket is connected with a train water injection nozzle, and the lower end of the water jacket is connected with a water feeding rubber pipe. The direct insertion type passenger train water feeding anti-pulling pipe quick connector is used for overcoming the defects of inconvenient operation, high labor intensity and low efficiency in the existing water feeding work of trains.

Description

technical field [0001] The invention relates to the technical field of connection between passenger car water supply equipment and train water injection nozzles, in particular to an in-line passenger train water supply anti-tension pipe quick connector. Background technique [0002] Existing quick joints mainly use rubber materials to make a cone-shaped barrel-shaped structure similar to the shape of the water injection nozzle of the train. The small-diameter end of the cone-shaped barrel is connected with a rubber hose using a pipe fitting. The rubber hose is connected to the water supply equipment, and the large cone-shaped end is inserted into the train. The water injection nozzle uses the deformation of the rubber to fit the water injection nozzle of the train to form friction, so as to realize the connection with the water injection of the train. This structure needs to manually screw the quick connector on the water injection nozzle of the train, which is extremely inc...

Problems solved by technology

[0004] The embodiment of the present invention provides an in-line passenger train water-loading anti-pull pipe quick connector, which is used to solve the defects of inconvenient operation, high labor intensity and low efficiency in the existing train water-filling work; at the same time, when the train starts, water injection When the nozzle and the water supply joint are not separated, the train water injection nozzle can be automatically separated from the train water injection nozzle by the pulling force generated by the train.
