Description

Technical Field

[0001] The utility model relates to the technical field of connecting pipes for train main air, in particular to a combined hose handshake for train main air. Background Art

[0002] The train is equipped with a pipeline system that provides compressed air, which is mainly used to power various pneumatic equipment on the train.

[0003] For combined trains, hoses are needed to connect the piping systems of different trains. After the hoses are connected, functions such as train braking can be used normally.

[0004] In the prior art, both ends of the hose connecting the pipe system have threaded connection ends, which are connected to each other through threaded connection, and the auxiliary tool can only use a manual wrench, which is not only inefficient, but also prone to the problem of installation tightness not meeting the requirements; when the threaded connection end is installed relatively loosely, the threaded connection end is easy to fall off during the process of strong vibration during train operation; when the threaded connection end is installed tightly, the thread structure is easy to be damaged. When disassembling and assembling, new threaded connection ends or hoses can only be replaced, which has a high cost.

[0005] For this reason, we provide a combined train main air hose handshake to solve the above problems. Utility Model Content

[0006] In view of the problems existing in the above-mentioned prior art, the utility model provides a combined train main air hose handshake, which solves the problems of low efficiency and difficulty in controlling the installation strength when installing the train main air hose using a wrench.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts a combined train main air hose handshake, comprising:

[0008] A hose, a connector and a winding reel, wherein two connectors and two winding reels are provided, the two connectors are rotatably arranged at both ends of the hose, and the winding reel is fixedly arranged at the outer ring of the hose and located on one side of the connector;

[0009] The outer ring of the connector is provided with an annular groove, one side of the annular groove is provided with a hexagonal groove, and an armrest ring is provided on the hexagonal groove. The inner ring of the armrest ring is a hexagonal groove structure, and the diameter of the annular groove is smaller than the vertical distance between the opposite sides of the hexagonal groove structure. A plurality of armrests are fixedly provided on the outer ring of the armrest ring;

[0010] A connecting plate is fixedly provided at the outer ring of the connecting head, and a pull rope is fixedly connected to the end of the connecting plate. The pull rope is wound on the winding reel. When the connecting head is tightened on the end of the train main air duct, the pull rope wound on the winding reel reaches a tightened state, and the end of the pull rope away from the connecting plate is fixed at the outer ring of the winding reel.

[0011] As a further optimization of the above solution, a display ring is provided on the inner wall of the winding coil, and when the pull rope is in a tightened state, the display ring just leaks out.

[0012] As a further optimization of the above solution, pin holes are provided at the outer rings of the connecting plate and the winding coil, and the two pin holes are relatively positioned by being engaged simultaneously by a pin rod.

[0013] As a further optimization of the above solution, an elastic rope is fixedly provided at the outer ring of the connecting plate, a pull ring is fixedly provided at the end of the pin rod, and the end of the elastic rope is wound and fixed on the pull ring.

[0014] As a further optimization of the above solution, the inner ring of the connector has an internal thread.

[0015] As a further optimization of the above solution, the inner circle of the winding coil is bonded and fixed to the outer circle of the hose.

[0016] The utility model is a combined train main air hose handshake, which has the following beneficial effects:

[0017] The utility model discloses a combined train main air hose handshake. When the connector needs to be connected to the end of the train main air duct, the handrail ring is slid to the outside of the hexagonal groove. Then, the corresponding handrail is toggled on either side of the outer ring of the handrail ring with one hand to make the handrail ring drive the connector to rotate, so that the connector is connected to the end of the train main air duct through threaded cooperation. The connection efficiency is high, which solves the problem of low efficiency when the existing wrench is generally used to install the train main air hose.

[0018] Because the vibration during the train process causes the connector to tend to detach or loosen, the pull rope will reversely tighten the connector to prevent the connector from detaching or loosening due to vibration;

[0019] When the pull rope is tightened, the display ring just leaks out, which can indicate that the connector is just rotated into place, making it easy to control the safety strength, and solving the problem of difficult control of installation strength when using a wrench to install the train main air hose.

[0020] With reference to the following description and drawings, a specific embodiment of the present invention is disclosed in detail, indicating how the principles of the present invention can be adopted. It should be understood that the scope of the embodiments of the present invention is not limited thereby, and within the spirit and scope of the appended claims, the embodiments of the present invention include many changes, modifications and equivalents.

[0027] Please refer to the instruction manual Figure 1-5 The utility model provides a technical solution: a combined train main air hose handshake, comprising: a hose 1, a connector 2 and a winding reel 3, wherein two connectors 2 and two winding reels 3 are provided, and the two connectors 2 are rotatably arranged at the two ends of the hose 1, and the winding reel 3 is fixedly arranged at the outer circle of the hose 1 and located on one side of the connector 2, and the inner circle of the winding reel 3 is bonded and fixed to the outer circle of the hose 1;

[0028] An annular groove 7 is provided at the outer ring of the connector 2, and the inner ring of the connector 2 has an internal thread. A hexagonal groove 6 is provided on one side of the annular groove 7, and a handrail ring 4 is provided on the hexagonal groove 6. The inner ring of the handrail ring 4 is a hexagonal groove structure, and the diameter of the annular groove 7 is smaller than the vertical distance between the opposite sides of the hexagonal groove structure. A plurality of handrails 5 are fixedly provided at the outer ring of the handrail ring 4. When the connector 2 needs to be docked with the end of the train main air duct, the handrail ring 4 is slid to the outside of the hexagonal groove 6, and then the corresponding handrail 5 on either side of the outer ring of the handrail ring 4 is toggled with one hand to make the handrail ring 4 drive the connector 2 to rotate, so that the connector 2 is connected to the end of the train main air duct through threaded cooperation, and the connection efficiency is high, which solves the problem of low efficiency when using a wrench to install the train main air hose.

[0029] After the connector 2 is connected to the end of the train's main air duct, the handrail ring 4 is slid into the annular groove 7. Since the annular groove 7 is a circular groove, the handrail ring 4 can rotate in the annular groove 7 without causing the connector 2 to rotate. Therefore, it is avoided that foreign objects touch the handrail 5 and cause the connector 2 to loosen or continue to be tightened.

[0030] Furthermore, a connecting plate 8 is fixedly provided at the outer ring of the connecting head 2, and a pull rope 13 is fixedly connected to the end of the connecting plate 8. The pull rope 13 is wound on the winding reel 3, and the end of the pull rope 13 away from the connecting plate 8 is fixed at the outer ring of the winding reel 3. When the connecting head 2 is tightened on the end of the main air duct of the train, the pull rope 13 wound on the winding reel 3 reaches a tightened state. If the connecting head 2 tends to detach and loosen due to vibration during the train process, the pull rope 13 will reversely tighten the connecting head 2 to prevent the connecting head 2 from detaching or loosening due to vibration.

[0031] In the present invention, a display ring 14 is provided on the inner wall of the winding reel 3. When the pull rope 13 is tightened, the display ring 14 just leaks out, which can indicate that the connector 2 is just rotated into place, making it convenient to control the safety strength, and solving the problem of difficult control of installation strength when using a wrench to install the train main air hose.

[0032] Furthermore, in the present invention, pin holes 12 are provided at the outer rings of the connecting plate 8 and the winding roll 3. The two pin holes 12 are simultaneously engaged and positioned relative to each other by a pin rod 11, thereby locking the connecting head 2 and the pull rope 13 at the same time, thereby preventing the connecting head 2 from loosening or continuing to tighten, and also preventing the tightened pull rope 13 from loosening.

[0033] During specific use, an elastic rope 9 is fixedly provided at the outer ring of the connecting plate 8, and a pull ring 10 is fixedly provided at the end of the pin rod 11. The end of the elastic rope 9 is wrapped and fixed on the pull ring 10. The pin rod 11 is easy to use. When the connecting head 2 needs to be rotated, the pin rod 11 can be taken out from the pin hole 12 through the pull ring 10. Moreover, since the elastic rope 9 connects the pull ring 10 and the pin rod 11, the pin rod 11 is not easy to lose.
