[0034] See also Figures 1 to 9The utility model shows a rotating connection mechanism, which includes a first connector 10 and a second connector 20. The first connector 10 can be an arc columnar structure, a circular columnar structure or a square arc structure, and the cross-sectional shape of the first connector 10 can be circular, elliptical, square, etc. Similarly, the second connector 20 can be an arc columnar structure, a circular columnar structure or a square arc structure, and the cross-sectional shape of the second connector 20 can be circular, elliptical, square, etc. Of course, the first connector 10 and the second connector 20 can also be other structural shapes and other sizes. Preferably, the first connector 10 and the second connector 20 can be made of plastic parts or plastic parts, or metal parts, and the material setting can be selected according to actual needs, and is not specifically limited here.

[0035] The first connecting body 10 is provided with a receiving groove 11. For example, the circumferential surface of the first connecting body 10 is concave inward to form the receiving groove 11. A columnar body 30 is provided in the receiving groove 11. The end surface of the columnar body 30 is provided with a first crown tooth portion 31. The first end of the second connecting body 20 is provided with a sleeve groove 21. The sleeve groove 21 is provided with a second crown tooth portion 22. The sleeve groove 21 is used to be sleeved on at least part of the outer periphery of the columnar body 30. The second crown tooth portion 22 is meshed with the first crown tooth portion 31. When the first connecting body 10 and the second connecting body 20 rotate relative to each other (such as Figure 1 , can be rotated from direction A to direction B), the first connector 10 and the second connector 20 can be rotated relative to each other, and have a certain damping feeling, which can improve the rotation feel, and the first connector 10 and the second connector 20 can be relatively fixed at a predetermined angle, without the need for other fixing devices for auxiliary fixation, which is more convenient. The number of teeth of the first crown tooth portion 31 and the second crown tooth portion 22 can be selected and set according to actual needs, and is not specifically limited here.

[0036] The surface of the first connecting body 10 at the opening of the accommodating groove 11 is provided with a guide limiting portion 12, and the first end of the second connecting body 20 is provided with an arc groove 23. The guide limiting portion 12 is located in the arc groove 23. The arc groove 23 can be a semicircular arc groove structure or a C-shaped groove structure. Of course, the size and shape of the arc groove 23 can be selectively set according to the required rotation range, and no specific limitation is made here.

[0037] When the second connecting body 20 rotates, the arc groove 23 can rotate along the guide limiting portion 12 , and can guide and limit the rotation angle of the second connecting body 20 to a certain extent.

[0038] like Figure 5 Figure and Figure 6As shown, in some embodiments, the column 30 can be roughly cylindrical, and the column 30 can be detachably installed in the receiving groove 11, so that the column 30 can be assembled into the receiving groove 11 and it is also convenient to replace the column 30. When the column 30 is damaged, it can be directly replaced.

[0039] The outer diameter of the columnar body 30 is smaller than the inner diameter of the receiving groove 11. After the columnar body 30 is installed in the receiving groove 11, its axial end can protrude from the periphery of the opening of the receiving groove 11. The columnar body 30 can be made of plastic or plastic parts, or metal parts, and its material setting can be selected according to actual needs, and is not specifically limited here.

[0040] like Figures 3 to 6 As shown, in some embodiments, a limiting column 13 is provided in the accommodating groove 11, and a limiting groove 32 is provided on the columnar body 30 and is sleeved on the limiting column 13. The limiting column 13 can be roughly cylindrical, and the limiting groove 32 can be roughly cylindrical. The outer diameter of the limiting column 13 is close to the inner diameter of the limiting groove 32 to achieve relative fixation. The axial dimension (or length dimension) of the limiting column 13 can be greater than or equal to the groove depth of the limiting groove 32. Of course, the limiting column 13 can be a triangular columnar structure or a square columnar structure, and the limiting groove 32 can be a triangular columnar groove structure or a square columnar groove structure, so that the two can be better fixed together relatively due to the existence of limiting edges in the structure. Of course, the limiting column 13 can also be other structures and other sizes, and the shape of the limiting groove 32 can be adapted to the limiting column 13, and no specific limitation is made here.

[0041] like Figures 3 to 6 As shown, in some embodiments, the inner side wall of the receiving groove 11 is provided with a plurality of protrusions 14, and the protrusions 14 are spaced apart from the limiting pillars 13. The circumferential outer surface of the columnar body 30 is provided with a plurality of recesses 33, and the recesses 33 are relatively fixed to the protrusions 14. The recesses 33 and the protrusions 14 can be mutually engaged and fixed together. Furthermore, the protrusions 14 can be a rib plate structure, and the recesses 33 can be a longitudinal groove structure. Figure 4 As shown, the convex parts 14 can be four arranged at intervals, and the four can be arranged roughly symmetrically, so that when the first crown tooth part 31 and the second crown tooth part 22 rotate relative to each other, the force between the columnar body 30 and the convex parts 14 is more uniform, so that the columnar body 30 is installed more firmly. Of course, the convex parts 14 can also be two, three or any other number, which is not specifically limited here.

[0042] like Figure 6As shown, in some embodiments, the structure of the columnar body 30 located between adjacent recesses 33 is provided with a groove 34, and the groove 34 can reduce the structural weight of the columnar body 30, and can effectively reduce the weight of the entire rotating connection mechanism while ensuring the overall rigidity of the columnar body 30.

[0043] In some embodiments, the columnar body 30 may be an integral structure with the first connecting body 10 .

[0044] like Figure 3 , Figure 4 , Figure 5 , Figure 8 , Fig. 9 As shown, in some embodiments, the surface of the first connecting body 10 located at the opening of the accommodating groove 11 is also provided with an annular groove 15, and the first end of the second connecting body 20 is provided with an annular convex wall 24 on the side facing the first connecting body 10, and the annular convex wall 24 is arranged in the annular groove 15, so that when the first connecting body 10 and the second connecting body 20 rotate relative to each other, the annular convex wall 24 and the annular groove 15 rotate relative to each other, which can improve the stability of the rotation.

[0045] like Figure 3 , Figure 4 , Figure 5 , Figure 8 , Fig. 9 As shown, the guide limit portion 12 is located at the inner circle of the annular groove 15. The surface of the first connector 10 located at the opening of the accommodating groove 11 is also provided with a connecting portion 16, and the connecting portion 16 can be located at the outer circle of the annular groove 15. The connecting portion 16 can be arranged opposite to the guide limit portion 12, such as symmetrically. Of course, the number and position of the connecting portion 16 can also be selected according to actual needs, and are not specifically limited here.

[0046] Furthermore, the rotation connection mechanism also includes a limit plate 40, a first fastener and a second fastener. The limit plate 40 is located on the side of the first end of the second connecting body 20 away from the first connecting body 10. The first fastener is passed through the limit plate 40 and connected to the connecting portion 16. The second fastener is passed through the limit plate 40 and connected to the guide limit portion 12 to limit the second connecting body 20 to prevent the second connecting body 20 from being separated from the first connecting body 10. The limit plate 40 can also be defined as a limit cover in some embodiments. The limit plate 40 can be made of plastic or plastic parts, or metal parts. The material setting can be selected according to actual needs and is not specifically limited here.

[0047] like Figure 5As shown, further, the connecting portion 16 and the guide limiting portion 12 are both columnar, such as cylindrical, the connecting portion 16 is provided with a first connecting hole 161, and the guide limiting portion 12 is provided with a second connecting hole 121. The limiting plate 40 is provided with a first through hole 41 and a second through hole 42 at intervals. The first fastener is provided through the first through hole 41 and is inserted into the first connecting hole 161, and the second fastener is provided through the second through hole 42 and is inserted into the second connecting hole 121.

[0048] Preferably, the first connection hole 161 and the second connection hole 121 may be screw holes, and the first fastener and the second fastener may be bolts or screws.

[0049] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 8 , Fig. 9 As shown, in some embodiments, the first connecting body 10 is provided with a first connecting structure 10a at both ends in the length direction; and / or, the second connecting body 20 is provided with a second connecting structure 20a at the second end. The first connecting structure 10a may be a groove structure, and the second connecting structure 20a may be a groove structure, so as to facilitate connection with a tubular member, etc. Of course, the first connecting structure 10a and the second connecting structure 20a may also be internal thread grooves or external thread portions, etc., which are not specifically limited here.

[0050] The rotating connection mechanism is assembled as follows:

[0051] The columnar body 30 is installed in the accommodating groove 11 of the first connecting body 10, the limiting groove 32 and the limiting column 13 are plugged and fixed to each other, the recessed portion 33 and the convex portion 14 are relatively engaged and fixed, the sleeve groove 21 of the second connecting body 20 is sleeved on at least part of the outer periphery of the columnar body 30, the second crown tooth portion 22 and the first crown tooth portion 31 are meshed with each other, and then the limiting plate 40 is installed, so that the second connecting body 20 and the first connecting body 10 can be relatively rotatably fixed together.

[0052] The ball frame of the ball frame of the related art is generally fixed, and its tilt angle cannot be adjusted, which has great limitations. Fig.10 As shown, the present application also discloses a ball frame, which can be used as a basketball frame, a rugby frame or a water polo frame, etc. The ball frame can be used for playing or training.

[0053] The ball frame includes two rotating connection mechanisms, the number of which is symmetrical, and the two first connecting bodies 10 are connected to arc-shaped bodies 50 at both ends in the length direction to form a ball frame. The arc-shaped body 50 can be an arc-shaped hose. The second ends of the two second connecting bodies 20 are connected to the supporting body 60 to form a frame.

[0054] When the angle of the ball frame needs to be adjusted, it is only necessary to relatively rotate the first connector 10 and the second connector 20 , thereby improving the applicability of the ball frame.

[0055] Of course, the rotating connection mechanism may also be provided with other devices and equipment, which are not specifically limited here.

[0056] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model.
