Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] like Figures 1-5As shown, this split-assembly multi-point lubrication cast traction seat includes a housing 1 and supports 2 fixedly connected to the left and right sides of the lower end face of the housing 1. A pull rod 7 mechanism is provided inside the housing 1. The pull rod 7 mechanism includes a handle rod 6, a pull rod 7, a pin block 3, and a locking hook 5 connected in sequence. A traction pin hole 8 is provided in the middle of the housing 1. The end of the handle rod 6 is hinged to one end of the pull rod 7, and the other end of the pull rod 7 is hinged to the housing 1. The middle part of the pull rod 7 is hinged to the pin block 3, and the other end of the pin block 3 is connected to one side of the locking hook 5. The locking hook 5 is rotatably mounted outside the traction pin hole 8. The locking hook 5 can engage the traction pin in the traction pin hole 8. Rotating the locking hook 5 can release the connection between the traction pin and the housing 1. The end of the handle rod 6 that is hinged to the pull rod 7 is also connected to a handle rod return spring 9. The end of the handle rod is connected, and the other end of the handle rod return spring 9 is connected to the housing 1. The handle rod 6 is driven to move outward to the housing 1. The handle rod 6 drives the locking hook 5 to rotate through the pull rod 7 and the pin block 3, releasing the traction pin and releasing the handle rod 6. Under the drive of the handle rod return spring 9, the locking hook 5 is reset. A locking hook return spring 10 is provided on the outside of the locking hook 5. One end of the locking hook return spring 10 is connected to the locking hook 5, and the other end of the locking hook return spring 10 is connected to the housing 1. The locking hook return spring 10 assists the locking hook 5 in resetting. The handle rod 6, pull rod 7, pin block 3, locking hook 5 and other parts can be shared with the same model of stamped and welded traction seat. Furthermore, the handle rod 6, pull rod 7, pin block 3 and locking hook 5 can all use the existing structure that has been produced, or can be optimized based on it.

[0023] The modular multi-point lubrication cast traction seat provided by this utility model has a supporting rib plate 11 on the front side of the housing 1 outside the traction pin hole 8. Bearing structures 12 are provided at both ends of the supporting rib plate 11. Unlike the prior art where the support 2 is rotatably mounted on the housing 1 via a rotating shaft 13, the rotating shaft 13 on the support 2 of this traction seat is rotatably mounted inside the bearing structure 12. A locking hook rotating pin hole 14 is provided on the front side of the housing 1 between the traction pin hole 8 and the supporting rib plate 11. A pull rod rotating pin hole 15 is provided on the front side of the housing 1 outside the supporting rib plate 11. The locking hook 5 is rotatably mounted to the locking hook rotating pin hole 14 via a locking hook bolt 16. The end of the pull rod 7 away from the handle rod 6 is rotatably mounted to the pull rod rotating pin hole 15 via a pull rod bolt 17. The traction seat also includes a locking hook fixing mounting plate 18 and a handle rod fixing mounting plate 19. The locking hook fixing mounting plate 18 is fixed to the support rib plate 19 via locking hook fixing mounting plate bolts 20. On the support rib plate 18, the locking hook 5 is restricted above the housing 1 by the locking hook fixing mounting plate 18, and the handle rod fixing mounting plate 19 is fixed to the limiting groove 28 by the handle rod fixing mounting plate bolt 21. The handle rod 6 is restricted within the limiting groove 28 by the handle rod fixing mounting plate 19. The handle rod 6, pull rod 7, pin block 3, locking hook 5, locking hook fixing mounting plate 18 and handle rod fixing mounting plate 19 can be progressively stacked and installed on the outside of the housing 1 and the open-ended support rib plate 11. There is no complicated installation operation such as plugging, making the installation simpler and simplifying the assembly process. The pin block 3, locking hook fixing mounting plate 18 and handle rod fixing mounting plate 19 are separate installation structures from the housing 1. Since the housing structure has no internal cavity structure that affects the demolding, there is no need to add complex processes such as core boxes during casting. The structure is simple, convenient for production, and solves the problem of difficult assembly of parts such as pin block 3, locking hook 5 and spring in subsequent assembly.

[0024] A lubrication system is also provided on the housing 1. The lubrication system includes a bearing lubrication hole 22, a lubrication oil passage 23, and an oil guide groove 24. The bearing structure 12 is provided with a bearing surface 25. The lubrication oil passage 23 and the bearing lubrication hole 22 are provided on the bearing surface 25 and penetrate the housing 1. One end of the lubrication oil passage 23 is provided on the end face of the housing 1 and can be connected to an external lubrication nozzle. The other end of the lubrication oil passage 23 is provided at the lubrication hole 26 in the oil guide groove 24 on the rear side of the housing 1. This can realize multi-point lubrication and provide a lubrication oil passage 23 provided inside the housing 1, which solves the problems of oil pipes being exposed to the outside and being prone to wear and heavy weight in the prior art.

[0025] The housing 1 is integrally formed with the supporting rib plate 11 and the bearing structure 12. The supporting rib plate 11 has a reinforcing rib 27 on the outside, which provides support for the inside of the housing 1. The supporting rib plate 11 is set as an open rectangle. The handle rod 6, the pull rod 7, the pin block 3 and the locking hook 5 can be installed in sequence. The locking hook 5 and the pin block 3 are prefabricated connecting parts, and there is no need to connect them again. The specific installation sequence is: locking hook 5 and pin block 3 - locking hook fixing plate 18 - pull rod 7 - handle rod 6 - locking hook fixing plate 19 - support 2 - handle rod return spring 9 - locking hook return spring 10. There is no complicated installation operation such as plugging. The locking hook fixing plate 18 and the handle rod fixing plate 19 are detachably installed on the housing 1 by bolts. The locking hook fixing plate 18 and the handle rod fixing plate 19 adopt a split structure to realize the convenient installation of the locking hook 5 and the pull rod 7 without plugging.

[0026] A limiting groove 28 is provided in the middle of the handle rod 6. The limiting groove 28 is fixed below the support 2 on the same side and limits the range of movement of the handle rod 6.

[0027] A limit rod 29 is provided on the edge of the support 2 away from the handle rod 6. The end of the limit rod 29 contacts the locking hook 5, and the rotation range of the locking hook 5 is limited by the limit rod 29.
