Description

Technical Field

[0001] The utility model relates to the technical field of hoses, and more specifically, to an adjustable hose handshake assembly. Background Art

[0002] A train includes locomotives at both ends and multiple carriages in the middle. An air compressor is provided at the locomotive of the train, and the main air source is transported from the locomotive to each carriage. The connecting hose is used to convey the air source from the main air pipe to each train pipe. The connecting hoses located on the two locomotives are not required to be used under normal train conditions. The connecting hoses need to be fixed on the hose handshakes. Only when the train breaks down (unable to supply air), the connecting hoses are removed from the hose handshakes and docked with the air supply equipment on the locomotive of the rescue train to meet the air supply requirements of the train carriages.

[0003] Currently, the hose handshakes used in trains are used to temporarily fix the hose connectors (installed at one end of the connecting hose for mating connection with the hose handshakes). When one end of the connecting hose (the end away from the hose connector) is screwed and fixed on the main air pipe valve, the orientation of the hose connector at the other end is not fixed (during the process of screwing the connecting hose on the main air pipe valve, the hose connector rotates together with the connecting hose).

Specifically, the lapping of the convex - block structure and the U - shaped structure is realized by inserting the convex - block structure into the U - shaped structure, and through the lapping of two groups of convex - block structures and U - shaped structures, it is beneficial to realize quick docking and positioning.

[0034] Optionally, the movable body 1 further includes a push rod 13 and a limit block 14. The push rod 13 penetrates through the body structure 11 and is movable relative to the body structure 11 along its extending direction. The limit block 14 is connected to one end of the push rod 13. A limit groove adapted to the shape of the limit block 14 is formed on the connector body 51, and the limit block 14 is configured to be disposed in the limit groove.

[0035] In this embodiment, in combination with the attached Figure 1 As shown, the push rod 13 is movably connected to the body structure 11 in the vertical direction (the Z-axis direction in the attached Figure 1 drawing). The push rod 13 may be in a T-shaped structure, which is convenient for an operator to manually operate the push rod 13. The limit block 14 can be connected to the lower end of the push rod 13 by bolts or welding. A limit groove adapted to the shape of the limit block 14 is formed on the connector body 51. The operator can manually operate the push rod 13 to make the limit block 14 fall into the limit groove, so as to realize the connection between the body structure 11 of the movable body 1 and the connector body 51. Specifically, through the lapping between the lapping portion of the movable body 1 and the mating portion of the hose connector 5, and combined with the connection between the body structure 11 of the movable body 1 and the connector body 51 through the push rod 13, the connection stability between the movable body 1 and the hose connector 5 can be ensured.

[0036] Optionally, the movable body 1 further includes a first spring 15. The radial dimension of the opening part of the groove 16 is larger than that of its bottom wall part, and the part of the groove 16 close to its opening is used to accommodate the limit block 14. The push rod 13 penetrates through the groove 16. The first spring 15 is sleeved on the push rod 13, and the first spring 15 is located in the groove 16. One end of the first spring 15 abuts against the bottom wall of the groove 16, and the other end abuts against the limit block 14.

[0037] In this embodiment, in combination with the attached Figure 1 As shown, a stepped groove 16 is formed on the body structure 11. The radial dimension of the part of the stepped groove 16 close to its opening is larger, which is convenient for accommodating the limit block 14. The radial dimension of the part of the stepped groove 16 close to its bottom wall is smaller, which is convenient for accommodating and limiting the first spring 15. The push rod 13 is in the vertical direction (the attached Figure 1The first spring 15 is sleeved on the push-pull rod 13 and is located in the groove 16, wherein the upper end of the first spring 15 abuts against the bottom wall of the groove 16, and the other end abuts against the upper surface of the stop block 14. The stop block 14 is located outside the groove 16 in the initial state, that is, the first spring 15 provides a force to push the stop block 14 downward. When the movable body 1 and the hose connector 5 need to be docked, the operator needs to pull the push-pull rod 13 upward to retract the stop block 14 into the groove 16 (at this time, the first spring 15 is in a compressed state). When the movable body 1 and the hose connector 5 are aligned, the operator releases the push-pull rod 13 to make the stop block 14 fall into the stop groove. In this way, under the action of the first spring 15, the stop block 14 will not fall out of the stop groove due to the vibration of the train, thereby ensuring the connection stability between the movable body 1 and the hose connector 5.

[0038] Optionally, the movable body 1 further includes a connecting shaft 17 , one end of which is connected to a side of the overlapping portion 12 away from the main body structure 11 , and the universal ball 3 is connected to the other end of the connecting shaft 17 .

[0039] In this embodiment, combined with the attached Figure 1 As shown, the left end of the connecting shaft 17 (attached Figure 1 The positive direction of the middle X-axis) can be connected to the right side wall of the overlap portion 12 by bolts, and the universal ball 3 can be connected to the right end of the connecting shaft 17 by bolts.

[0040] Optionally, a flexible dust cover 4 is sleeved on the connecting shaft 17, and the flexible dust cover 4 is used to prevent dust from entering the spherical cavity.

[0041] In this embodiment, combined with the attached Figure 1 As shown, a flexible dust cover 4 is sleeved on the connecting shaft 17, wherein the flexible dust cover 4 can be made of rubber material to prevent dust from entering the spherical cavity.

[0042] Optionally, the fixed body 2 includes a cylinder 21 and a disc structure 22 , the disc structure 22 is connected to one end of the cylinder 21 , and the spherical cavity is formed at one end of the cylinder 21 away from the disc structure 22 .

[0043] In this embodiment, combined with the attached Figure 1 and attached Figure 3 As shown, the fixed body 2 includes a cylinder 21 and a disc structure 22 , wherein the disc structure 22 can be connected to one end of the cylinder 21 by welding, and the spherical cavity is opened at one end of the cylinder 21 away from the disc structure 22 .

[0044] Optionally, the fixed body 2 further includes a nut structure 23 for threadedly connecting with the cylinder 21 to adjust the tightness of the spherical cavity holding the universal ball 3.

[0045] In this embodiment, as shown in the accompanying Figure 1 figures, an external thread is provided on the outer surface of the cylinder 21, and an internal thread is provided on the inner wall of the nut structure 23. The nut structure 23 can be threadedly connected to the cylinder 21. By adjusting the degree of screwing of the nut structure 23 on the cylinder 21, the tightness of the universal ball 3 in the spherical cavity can be adjusted.

[0046] Optionally, the fixed body 2 further includes a pin shaft 24 and a second spring 25. The nut structure 23 is provided with a through first through hole along its axial direction, and a plurality of second through holes are provided on the disk structure 22 at intervals along its circumferential direction. The pin shaft 24 is used to pass through the first through hole and the second through hole. A receiving groove is provided on the inner wall of the first through hole. A shoulder 241 is provided on the pin shaft 24. The second spring 25 is sleeved on the pin shaft 24. Both the shoulder 241 and the second spring 25 are located in the receiving groove. One end of the second spring 25 abuts against the shoulder 241, and the other end abuts against the inner wall of the receiving groove away from the first through hole.

[0047] In this embodiment, as shown in the accompanying Figure 1 and the accompanying Figure 2 figures, vibrations will occur during the running of the train, which may easily cause the nut structure 23 to become loose on the cylinder 21. Based on this, a through first through hole is provided on the nut structure 23 along its axial direction. The diameter of the disk structure 22 is larger than that of the cylinder 21. Second through holes are provided near the edge of the disk structure 22. The pin shaft 24 is used to pass through the first through hole and the second through hole to improve the connection stability between the nut structure 23 and the cylinder 21.

[0048] Moreover, to prevent the pin shaft 24 from affecting the relative rotation between the nut structure and the cylinder 21, in this embodiment, the fixed body 2 is further provided with a second spring 25. The second spring 25 is sleeved on the pin shaft 24 and is located in a receiving groove formed in the inner wall of the first through hole. A shoulder 241 is provided on the pin shaft 24, and the shoulder 241 is also located in the receiving groove. By arranging the shoulder 241 in the receiving groove, the pin shaft 24 can be prevented from disengaging from the first through hole. Moreover, one end of the second spring 25 abuts against the shoulder 241, and the other end abuts against the inner wall of the receiving groove. Since the second spring 25 can elastically expand and contract, when it is necessary to adjust the relative rotation between the nut structure and the cylinder 21, a force can be applied to the pin shaft to compress the second spring 25, so that the pin shaft 24 disengages from the second through hole of the disc structure 22. At this time, the nut structure 23 can be screwed into the disc structure 22 and the cylinder 21. When the nut structure 23 is screwed into place relative to the disc structure 22 and the cylinder 21, the force applied to the pin shaft 24 can be released. At this time, the pin shaft 24 moves towards the disc structure 22 under the action of the elastic restoring force of the second spring 25 and inserts into the second through hole of the disc structure 22, so that the nut structure 23 cannot rotate relative to the disc structure 22 and the cylinder 21. Thus, the pin shaft 24 can prevent the nut structure 23 from loosening. In this way, through the arrangement of the second spring 25, it not only does not affect the screwing movement between the nut structure 23 and the cylinder 21 and the disc structure 22, but also can prevent the nut structure 23 from loosening, improving the connection stability between the nut structure 23 and the cylinder 21.

[0049] Optionally, the fixed body 2 further includes a connection seat 26. The connection seat 26 is connected to the end face of the disc structure 22 facing away from the cylinder 21. The connection seat 26 has a U-shaped structure, and a long slot 261 is formed in the middle thereof. A connection hole is formed in the handshake mounting bracket, and the long slot 261 and the connection hole are used for bolt connection to mount the connection seat 26 on the handshake mounting bracket.

[0050] In this embodiment, in combination with the attached Figure 1 and the attached Figure 3 As shown, the connection seat 26 has a U-shaped structure, and a long slot 261 is formed in the middle thereof. The handshake mounting bracket is usually an L-shaped bracket structure, and a connection hole is formed thereon. The long slot 261 and the connection hole are used for bolt connection to mount the connection seat 26 on the handshake mounting bracket.

[0051] The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0052] Although the present utility model is disclosed as above, the protection scope of the present utility model is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model, and these changes and modifications will all fall within the protection scope of the present utility model.
