Detailed implementation manners

[0024] For the convenience of those skilled in the art to understand, the present utility model will be further described below in conjunction with the embodiments and the drawings. The content mentioned in the implementation manners does not limit the present utility model. The present utility model will be described in detail below with reference to the drawings. Embodiment

[0025] Please refer to Figures 2 - 4 , a specific implementation of a bearing journal with rope protection includes a support main body 1. The top end of the support main body 1 has a journal part 12 that contracts inward, and the journal part 12 is used for sleeving and fixing the rope. The top end of the support main body 1 is a module fixing part 11 for fixing the object to be lifted. The module fixing part 11 is composed of a polygonal columnar body, and several insertion holes 111 are provided in the middle of the module fixing part 11. When connecting the object to be lifted, an external bolt can pass through the insertion holes 111 and then be threadedly connected to the surface of the object to be lifted, effectively connecting the support main body 1 and the object to be lifted.

[0026] A rotatable top cover 2 is provided at the top end of the journal part 12. A fastening part 3 extending downward is provided on one side of the top cover 2. A fastening groove 32 is provided on the inner wall of the fastening part 3. The horizontal height of the fastening groove 32 is the same as that of the journal part 12. A protection area 6 for preventing the rope from falling off is formed between the fastening groove 32 and the journal part 12. A reset connecting part 4 is provided between the top of the fastening part 3 and one side of the top cover 2. The fastening part 3 is movably connected to the top cover 2 through the reset connecting part 4, and the fastening part 3 can swing along the edge of one side of the top cover 2 with the reset connecting part 4 as the axis.

[0027] A buckling piece 3 extending downward is provided on one side of the top cover 2, and a buckling groove 32 is provided on the inner wall of the buckling piece 3. The horizontal height of the buckling groove 32 is consistent with the shaft neck 12, and a protection area 6 for preventing the rope from falling off is formed between the buckling groove 32 and the shaft neck 12. When the rope forms a loop and is connected to the shaft neck 12, the buckling piece 3 can firmly buckle the buckling groove 32 inside the protection area 6 through the resetting connector 4, and the stability can be greatly improved.

[0028] Specifically, Figure 3 As shown, one end of the neck portion 12 away from the module fixing portion 11 is an upwardly extending limiting protrusion 13, and a sleeve hole 21 is opened in the middle of the top cover 2. The top cover 2 is rotatably sleeved on the middle of the limiting protrusion 13 through the sleeve hole 21. When the direction of the rope located at the neck portion 12 needs to be adjusted, one side of the top cover 2 can be moved so that the top cover 2 can be rotated along the middle of the limiting protrusion 13, so that the top cover 2 can play a role of universal rotation adjustment.

[0029] Specifically, Figure 3 As shown, the reset connector 4 includes a connecting pin 41 and a torsion spring 42, the torsion spring 42 is sleeved in the middle of the connecting pin 41, and one end of the torsion spring 42 is in contact with the top cover 2, and the other end of the torsion spring 42 is in contact with the buckle 3, a connecting slot 22 is provided on one side of the top cover 2 close to the buckle 3, a rotating protrusion 31 is provided on the top of the buckle 3, the middle of the connecting pin 41 is plugged with the rotating protrusion 31, and both ends of the connecting pin 41 are rotatably embedded in the inside of the connecting slot 22;

[0030] Under the action of the elastic stress of the torsion spring 42 itself, the elastic stress of downward swinging can be continuously applied to the fastener 3, so that the fastener 3 can be firmly attached to the shaft neck 12, maintaining the high strength and stability of the protection area 6. When it is necessary to open the fastener 3 and separate it from the shaft neck 12, the end of the wrench can be inserted into the gap between the rope and the buckle groove 32, and the wrench can be turned to flip the fastener 3 upward along the connecting pin 41 as the axis.

[0031] Among them, in a further embodiment, Figures 2 - 4 As shown, an end surface of the fastening member 3 away from the buckle groove 32 is provided with a lever 5 extending outward, the axial direction of the lever 5 and the fastening member 3 are parallel to each other, a connecting threaded hole 33 is provided in the middle of the fastening member 3, and the end of the lever 5 is screwed and fixed to the middle of the fastening member 3 through the connecting threaded hole 33;

[0032] An outwardly extending lever 5 is provided on one end face of the fastening member 3 away from the fastening groove 32, so that the lever 5 can be connected with the pin 41 as a fulcrum to form a lever structure. The operator can manually push the lever 5 without the aid of external tools to make the fastening member 3 flip upward along the connecting pin 41 as the axis, thereby expanding the opening of the protective area 6 and removing the knotted ring from the shaft neck 12. Example

[0033] See also Figure 5 , which specifically implements a supporting shaft neck with rope protection, wherein the parts of the supporting shaft neck in Example 2 that are the same as those in Example 1 are not repeated here, and the difference lies in that the module fixing portion 11 is composed of a cylindrical threaded portion 11a. When connecting an object to be lifted having a matching threaded hole, the module fixing portion 11 composed of the cylindrical threaded portion 11a can be directly threadedly connected to the matching threaded hole, thereby effectively connecting the support main component 1 to the object to be lifted.
