DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of this patent to clearly and completely describe the technical solutions in the embodiments of this patent. Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0025] See also Figure 1-4 , this patent provides a technical solution:

[0026] In the technical solution, a reel assembly with an anti-loosening structure includes two bearing seats 3, a reel body 1 is mounted between the two bearing seats 3, and reel hubs 5 are installed on both side walls of the reel body 1;

[0027] The side walls of the reel hubs 5 on both sides are equipped with rotating shafts 2, which are installed in the bearing seats 3;

[0028] The bearing seat 3 includes a shaft cylinder a301 and a shaft cylinder b302 which are arranged opposite to each other. The inner walls of the shaft cylinder a301 and the shaft cylinder b302 are evenly provided with a rotation cavity 22, and a ball 23 is installed inside the rotation cavity 22.

[0029] The ball 23 is arranged in close contact with the rotating shaft 2;

[0030] The two side walls of the shaft cylinder a301 and the shaft cylinder b302 are both installed with connecting plates 25, and the side walls of the connecting plates 25 are provided with mounting holes 24, and the mounting holes 24 are equipped with fasteners 4;

[0031] The fastener 4 includes a fastening screw 6 and an anti-slip screw 10, and a fastening nut 7 is threadedly connected to the outside of the fastening screw 6;

[0032] In this technical solution, the rotating shaft 2 can rotate in the bearing seat 3, thereby driving the reel body 1 to rotate. The bearing seat 3 is composed of two semicircular shaft cylinders a 301 and b 302 with the same structure. The bearing seat 3 is divided into two parts, which can be easily maintained and assembled. The inner walls of the shaft cylinders a 301 and b 302 are evenly and equidistantly provided with rotating cavities 22 along their centers. The balls 23 can rotate in the rotating cavities 22. When the rotating shaft 2 fitted thereto rotates, the balls 23 rotate successively, thereby maintaining the rotation stability of the rotating shaft 2. The shaft cylinders a 301 and b 302 can be prevented from loosening by the setting of the connecting plate 25 and the fastener 4.

[0033] In some technical solutions, reference Figure 1-4 The bottom end of the fastening screw 6 is provided with an anti-slip groove 8, and the anti-slip screw 10 is screwed into the anti-slip groove 8; the outer portion of the anti-slip screw 10 is sleeved with an anti-slip cylinder 9, and the outer wall of the anti-slip cylinder 9 is provided with three limiting columns 17, and the three limiting columns 17 are distributed in a triangular shape;

[0034] The inner wall of each limiting column 17 is provided with a spiral groove 18 that matches with the fastening screw 6 .

[0035] In this technical solution, the fastening screw 6 and the fastening nut 7 cooperate to realize the bolt in the prior art, and an anti-slip groove 8 is set at the bottom end of the fastening screw 6, and the anti-slip screw 10 is screwed in. Three limiting columns 17 installed on the anti-slip cylinder 9 outside the anti-slip screw 10 support the fastening nut 7, thereby circumferentially limiting the fastening nut 7, and the spiral groove 18 on the limiting column 17 engages with the fastening screw 6, thereby limiting the anti-slip cylinder 9 and the anti-slip screw 10.

[0036] In some technical solutions, reference Figure 1-4 The inner wall of the anti-slip cylinder 9 is provided with a reverse internal thread 19 , and the outer part of the anti-slip screw 10 and the anti-slip cylinder 9 are provided with a reverse external thread, and the reverse internal thread 19 and the reverse external thread 20 match each other.

[0037] In this technical solution, the external thread of the anti-slip screw 10 is divided into two parts, the front part cooperates with the internal thread of the anti-slip screw groove 8, and the rear part cooperates with the reverse internal thread 19 of the anti-slip cylinder 9, thereby installing the anti-slip cylinder 9 on the outside of the anti-slip screw 10.

[0038] In some technical solutions, reference Figure 1-4 The outer wall of the fastening nut 7 is provided with an annular rotation groove 11 , and the end of the limiting column 17 is arranged in the annular rotation groove 11 .

[0039] In this technical solution, when the anti-slip screw 10 is screwed into the anti-slip groove 8, the anti-slip cylinder 9 will rotate accordingly, and when the limiting column 17 contacts the fastening nut 7, it can rotate in the annular groove 11 until it contacts the inner wall of the annular groove 11, thereby supporting the fastening nut 7 for circumferential limiting.

[0040] In some technical solutions, reference Figure 1-4 A fixing ring 12 is fixedly mounted on the outer upper end of the fastening screw 6 , and an annular pressing sheet 14 , a spring 16 and an annular rubber sheet 15 are mounted on the circumferential surface of the fastening screw 6 .

[0041] In this technical solution, when the fastening screw 6 is rotated, the annular rubber sheet 15 slides upward due to the action of the screw hole. With further twisting, the annular rubber sheet 15 contacts the fixing ring 12. The annular rubber sheet 15 is deformed due to the action of the fixing ring 12 to seal the screw hole. The spring 16 is located on the upper side of the annular pressing sheet 14, so that the annular pressing sheet 14 is squeezed downward due to the action of the spring 16. The extrusion block 13 is squeezed downward due to the action of the annular pressing sheet 14, so that the extrusion block 13 further squeezes the edge of the annular rubber sheet 15, thereby improving the sealing effect. The annular pressing sheet 14 is located on the upper side of the fixing ring 12, the spring 16 is located on the upper side of the annular pressing sheet 14, the annular rubber sheet 15 is located on the lower side of the fixing ring 12, and the extrusion block 13 is fixedly installed at the lower end edge of the annular pressing sheet 14.

[0042] In some technical solutions, reference Figure 1-4 A winding groove 20 is distributed on the outer side of the reel body 1, a fixing plate 303 is installed on the rear side wall of the shaft cylinder a301 and the shaft cylinder b302, and a supporting column 21 is installed on the bottom end of the fixing plate 303.

[0043] In this technical solution, the assembled bearing seat 3 is installed on the support column 21 through the fixing plate 303.
