Technical Field

[0001] The utility model relates to the technical field of oil pipe connection, in particular to a railway locomotive high-pressure oil pipe joint which is convenient for quick installation. Background Art

[0002] Locomotives are the basic power of railway transportation. The traction of passenger and freight trains and the shunting operations at stations are all undertaken by locomotives. Locomotives play an important role in the safety, punctuality, high-speed running, high quality and low consumption of railway transportation. They are also key equipment for the development of the railway transportation industry. In railway locomotives, high-pressure oil pipe connectors are used to connect oil pipes to transmit high-pressure oil.

[0003] Existing oil pipe joints are usually connected by internal and external threads. During use, due to the short length of the threaded section, they are prone to falling off under long-term high-pressure use and vibration. In addition, some installation positions are relatively harsh and it is not convenient to use a wrench, resulting in low installation efficiency. Utility Model Content

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] Example 1

[0030] Reference Figure 1-Figure 4 A railway locomotive high-pressure oil pipe connector that is easy to install quickly is used in the field of oil pipe connection, including: a first connector 1 and a second connector 2, wherein one side of the second connector 2 is plugged into the first connector 1, and one end of the second connector 2 is tapered, which is adapted to the tapered inner wall of one end of the first connector 1. This design facilitates the positioning and plugging of the first connector 1 and the second connector 2.

[0031] The sliding ring 8 is rotatably sleeved on the second connecting head 2, and the outer wall of the sliding ring 8 is fixedly sleeved with a mounting ring 4. A plurality of pins 11 are penetrated through the outer wall of the mounting ring 4, and a slot 17 for cooperating with the plurality of pins 11 is provided on the outer wall of the first connecting head 1. When the pin 11 is inserted into the slot 17, the first connecting head 1 and the second connecting head 2 can be fixed, thereby achieving quick installation.

[0032] In addition, the sleeve 3 is fixedly sleeved on the second connector 2, forming an installation space therebetween for installing the oil pipe. A rectangular hole 7 is also provided on the outer wall of the sleeve 3. This observation hole is used to observe the position of the oil pipe in the sleeve 3, making it convenient for users to install and adjust.

[0033] In order to simultaneously drive multiple pins 11 to move and insert into the slots 17, the present invention also designs a braking mechanism, which includes a rotating ring 6 rotatably sleeved on the outer wall of the mounting ring 4, and the inner wall of the rotating ring 6 is fixedly provided with multiple protrusions 18 used in conjunction with the pins 11. A bolt 5 is threaded through one side of the mounting ring 4, and one side of the bolt 5 conflicts with the rotating ring 6 to limit the rotating ring 6. When it is necessary to fix the first connector 1 and the second connector 2, it is only necessary to rotate the bolt 5 to separate it from the rotating ring 6, and then rotate the rotating ring 6 to make the protrusion 18 push the pin 11 to move until the pin 11 is inserted into the slot 17. Finally, rotate the bolt 5 again to make it conflict with the rotating ring 6 to limit the rotating ring 6, thereby maintaining the position of the pin 11 in the slot 17.

[0034] In order to further optimize the structure, the inner end of the pin 11 is provided with an inclined surface 16 used in conjunction with the slot 17. When the pin 11 moves, the inclined surface 16 can further guide the second connector 2 to be inserted into the first connector 1, ensuring the accuracy and stability of the connection.

[0035] A limiting ring 13 is fixedly provided on the inner wall of the rotating ring 6, and a plurality of protrusions 18 are evenly distributed on the inner wall of the limiting ring 13. At the same time, a rectangular opening 12 corresponding to the limiting ring 13 is opened at the outer end of the pin 11 to limit the pin 11 and prevent it from rotating during movement.

[0036] In order to realize the reset movement of the pin 11, an annular groove 9 is opened at one end of the mounting ring 4, and the outer wall of the pin 11 is fixedly sleeved with a positioning ring 14 located in the annular groove 9. The outer wall of the pin 11 is also sleeved with a spring 15 located in the annular groove 9, and the two ends of the spring 15 are respectively fixedly connected to the inner wall of the annular groove 9 and one side of the positioning ring 14. When the rotating ring 6 rotates to separate the protrusion 18 from the pin 11, the elastic force of the spring 15 will push the pin 11 to reset and move, which is convenient for the next use.

[0037] In addition, a plurality of positioning blocks 19 used in conjunction with the plurality of protrusions 18 are fixedly disposed on the outer wall of the mounting ring 4 . The positioning blocks 19 are used to limit the positions of the protrusions 18 to ensure that the protrusions 18 can accurately push the pins 11 to move.

[0038] In order to improve the sealing of the joint, a sealing gasket 10 is also provided at one end of the first connector 1, and the other end of the sealing gasket 10 is in contact with the sliding ring 8. When the first connector 1 and the second connector 2 are connected, the sealing gasket 10 can further ensure the sealing between the two and prevent leakage of high-pressure oil.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
