DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0025] See also Figure 1-4 As shown, the utility model is an adjustable connection structure of a rigging, comprising an adjustable connection portion, the adjustable connection portion comprising a connection frame 14;

[0026] The connecting frame 14 can be connected to an external lifting rope to cooperate with the use of a hook to lift the cargo to be lifted.

[0027] The connecting frame 14 is configured to be open and rounded at its edges and corners.

[0028] The adjustable connection portion further includes an adjusting threaded tube 11, an adjusting threaded column 12, and a connecting ring 13; the adjusting threaded tube 11 is fixedly connected to the middle portion of the upper end of the rigging, and the adjusting threaded column 12 is provided on the inner thread of the middle portion of the adjusting threaded tube 11, and the connecting ring 13 is fixedly connected to the upper portion of the outer surface of the adjusting threaded column 12, and the opposite sides of the outer surface of the connecting ring 13 are fixed to the lower end portion of the connecting frame 14;

[0029] The connecting ring 13 is installed and fixed between the connecting frame 14 and the adjusting threaded column 12. The adjusting threaded column 12 is extended and retracted in the adjusting threaded tube 11 to adjust the connecting frame 14 and meet different lifting requirements.

[0030] Connecting guide part, the connecting guide part includes a mounting groove 21, a guide frame 22, a movable groove 23, a bracket 24 and a guide roller 25; the mounting groove 21 is opened at the central position of the inner top of the connecting frame 14, and the mounting groove 21 is fixedly connected to the guide frame 22, and the inner upper surface of the guide frame 22 is equidistantly opened with movable grooves 23, and the end of the top of the inner wall of the movable groove 23 is fixed with a movable spring, and the lower end of the movable spring is fixed with a bracket 24, and the lower part of the inner side of the bracket 24 is rotatably connected to the guide roller 25, and the guide roller 25 extends out of the movable groove 23 and rolls in contact with the lifting rope;

[0031] The installation groove 21 is used to structurally install the guide frame 22, and the guide frame 22 is used in conjunction with the bracket 24 and the movable spring to structurally install the guide roller 25. The depth of the movable groove 23 and the elastic expansion and contraction of the movable spring can meet the needs of the up and down position adjustment of the guide roller 25, and the contact with the external lifting rope in a rolling contact manner can reduce the friction between the two, thereby reducing the probability of falling off during subsequent lifting.

[0032] The guide frame 22 is configured in an arc shape, and the inner wall of the guide frame 22 is configured with a smooth surface.

[0033] Working principle: Apply rotational force to the adjusting threaded column 12 in advance, adjust the height of the connecting frame 14 by adjusting the threaded column 12 in the adjusting threaded tube 11, and then pass the external lifting rope through the lower part of the guide frame 22. A plurality of guide rollers 25 are evenly spaced on the inner wall of the guide frame 22. At this time, the external lifting rope is in contact with the plurality of guide rollers 25. When the external lifting rope is pulled, the rolling contact between the two can satisfy the external lifting rope for appropriate position adjustment. Then, connect the external lifting rope to the external lifting equipment, and hook the hook with the cargo to be lifted.

[0034] This solution utilizes multiple guide rollers 25 to contact the external lifting rope. When the lifting rope is moved, the rolling friction contact can reduce the friction generated by the hard contact between the two, reduce the wear on the surface of the lifting rope, save costs, and reduce safety risks during lifting.

[0035] See also Figure 1-4As shown, this embodiment is based on the above-mentioned embodiment 1 and further includes a limiting portion, which includes a limiting threaded tube 31, a limiting frame 32, a torsion spring 33, a limiting plate 34 and a limiting spring 37; the limiting threaded tube 31 is symmetrically fixedly connected to the upper part of the front and rear ends of the guide frame 22, and the limiting frame 32 is connected to the limiting frame 32 through the inner thread of the limiting threaded tube 31. The torsion spring 33 is penetrated on both sides of one end of the limiting frame 32, and the inner side of the torsion spring 33 is fixed to the end of one end of the limiting plate 34. The limiting spring 37 is fixedly connected to the end of the middle part of the inner side of the limiting plate 34;

[0036] The limiting threaded tube 31 is threadedly installed on the limiting frame 32, and the position of the bracket 24 can be adjusted by using the thread extension. The limiting frame 32 is fixed to the limiting plate 34 with a torsion spring 33. The torsion spring 33 relies on its own elastic force to restore the limiting plate 34 to its original state after use. The limiting plate 34 is used in conjunction with the limiting spring 37 to limit the external suspension rope to prevent shaking while meeting the autonomous adjustment of the force.

[0037] The limiting portion further includes a mounting block 35 and a mounting bolt 36. The mounting block 35 is symmetrically arranged in the middle of the front and rear ends of the guide frame 22. The mounting bolt 36 extends through the end of the mounting block 35 and extends into the guide frame 22. The two sides of the central position of the outer side of the mounting block 35 are fixed to one end of the limiting spring 37.

[0038] The mounting block 35 is used in conjunction with a mounting bolt 36 to fix one end of the limiting spring 37 .

[0039] Working principle: After the external suspension rope is guided and adjusted to the appropriate position as mentioned above, a rotational force can be applied to the limiting plate 34, and the limiting plate 34 originally set with the lower end facing upward can be converted to be set with the lower end facing downward, so that the inner side of the lower end of the limiting plate 34 conflicts with the external suspension rope. During the conflict, the limiting spring 37 is deformed by the force and can independently adjust the position of the limiting plate 34. After the limiting plate 34 is used, the torsion spring 33 and the limiting spring 37 recover their deformation after releasing the force to restore the original position.

[0040] This solution can meet the angle adjustment requirements of the limiting plate 34, while meeting the structural requirements of the external suspension rope, avoiding hard friction between the two, further reducing the probability of surface damage to the external suspension rope, further reducing costs, and meeting usage requirements.
