[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] Example

[0020] See also Figure 1 - Figure 4The utility model provides a technical solution: a pushing device for quickly loading a brake pipe, comprising a shell 1, a bushing 2, a spring 3, a fixing plate 6 and a clip spring 7. The inside of the shell 1 is movably connected with the bushing 2, and a spring 3 is fixedly installed on one side of the bushing 2. The spring 3 is elastic and plays an auxiliary role. The spring 3 is located inside the shell 1, and a fixing plate 6 is fixedly installed on one side of the shell 1. The outer end of the fixing plate 6 is symmetrically fixedly installed with a clip spring 7. The two clip springs 7 are in the form of hooks to quickly connect the two joints together, and a rubber sleeve is used to increase the reliability of its fixation.

[0021] Furthermore, a first sealing ring 4 is fixedly installed on the outer end of the housing 1. The material of the first sealing ring 4 is silicone and has a good sealing effect. A copper gasket 5 is movably connected to one side of the first sealing ring 4. The copper gasket 5 is used to fill the gap between mechanical parts to prevent leakage of fluid and particulate matter. The copper gasket 5 and the fixed plate 6 are fixedly connected.

[0022] Furthermore, rubber sleeves 8 are movably installed on the outer ends of the two clamping springs 7. The rubber sleeves 8 are made of rubber and fix the spring sheets to increase the force of the spring sheets to bounce open, thereby ensuring a secure connection. A joint valve 9 is fixedly installed inside the outer shell 1. There is a one-way valve inside the joint body of the joint valve 9. When the male and female joints are separated, the valve core of the one-way valve extends downward and outward under the action of their respective springs and is nailed to the conical lock hole of the joint body, thereby closing the passage.

[0023] Furthermore, a second sealing ring 10 is symmetrically fixedly installed inside the joint valve 9 , and the second sealing ring 10 makes the sealing effect of the connection better. A valve core 11 is fixedly installed on one side of the second sealing ring 10 , and the valve core 11 is fixedly installed inside the housing 1 .

[0024] Furthermore, the rubber sleeve 8 is symmetrically and fixedly installed with connecting blocks 12, which make the connection more secure, and the two connecting blocks 12 are installed opposite to each other.

[0025] Furthermore, a fixing block 13 is symmetrically fixedly installed on the outer end of the bushing 2 , and a fixing groove 14 is provided at the outer ends of the two fixing blocks 13 . The fixing groove 14 and the fixing block 13 are adapted in size, and the two fixing grooves 14 are opened on the inner wall of the housing 1 .

[0026] To sum up: this joint is installed in advance on the bushing 2. During on-site installation, just insert the end of the retaining spring 7 into the system end of the vehicle body brake pipe. At this time, the retaining spring 7 is buckled into the system end slot to prevent the brake pipe from falling out. The rubber sleeve 8 fixes the spring sheet to increase the force of the spring sheet to bounce open and ensure a secure connection. During use, the first sealing ring 4 is used to seal the connection, and then the copper gasket 5 is used to reinforce the seal to fill the gap between the mechanical parts and prevent leakage of fluid and particulate matter. When installed on the bushing 2, the fixing blocks 13 on both sides of the bushing 2 are clamped in the inside of the fixing groove 14 to make the installation more convenient and firm.
