[0045] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

The concave bearing member is formed at the end of the concave joint end tube and forms an angle with the concave joint end tube. The outer diameter limiting member is formed on the outside of the concave bearing member, and the inner diameter limiting member is formed on the inside of the concave bearing member. A gap is left between the outer diameter limiting member and the inner diameter limiting member. The circumferential positioning member is formed in the outer diameter limiting member. The convex bearing member The component is formed at the end of the convex joint end tube, and cooperates with the outer diameter limiting component, and forms an angle with the convex joint end tube. The inner diameter matching component is formed on the inner side of the convex load-bearing component, and cooperates with the inner diameter limiting component. The concave joint end tube and the convex joint end tube are connected by the inner diameter matching component and the inner diameter limiting component. The inner diameter matching component and the inner diameter limiting component can rotate with each other, so that the concave joint end tube and the convex joint end tube form different angles. The circumferential matching component is formed in the convex load-bearing component, and cooperates with the circumferential positioning component. The circumferential matching component circumferentially positions the convex load-bearing component and the circumferential positioning component, and then positions the angle formed between the concave joint end tube and the convex joint end tube.

[0047] In this embodiment, the concave load-bearing component includes a load-bearing end ring 110, which is formed at the end of the concave joint end tube. Its axis forms a 45° angle with the axis of the concave joint end tube, and its inner edge protrudes toward the inside of the concave joint end tube to form a avoidance opening. The interior of the concave joint end tube can be connected to the outside through the avoidance opening, and its outer edge protrudes toward the outside of the concave joint end tube.

[0048] The outer diameter limiting component includes a limiting outer ring 120, which is formed at the outer edge of the load-bearing end ring, extends along the circumference of the load-bearing end ring, and protrudes outward along the axial direction of the load-bearing end ring. The load-bearing end ring and the limiting outer ring enclose a containing space.

[0049] The inner diameter limiting component includes a limiting inner ring 131 and a limiting flange 132. The limiting inner ring is formed on the inner edge of the load-bearing end ring, extends along the circumference of the load-bearing end ring, and protrudes axially toward the outside of the load-bearing end ring. A gap is left between the limiting outer ring and the limiting inner ring. The limiting flange is formed on the inner wall of the limiting inner ring, extends along the circumference of the limiting inner ring, and protrudes radially toward the inside of the limiting inner ring.

[0050] In this embodiment, an expansion and contraction gap 133 is opened in the limiting inner ring, and a group of expansion and contraction gaps are provided. Each expansion and contraction gap extends along the axial direction of the limiting inner ring and is arranged sequentially along the circumference of the limiting inner ring, so that the limiting inner ring can expand outward or retract inward.

[0051] The circumferential positioning component includes a group of positioning notches 140 , each of which is respectively opened on the inner wall of the limiting outer ring and arranged in sequence along the circumference of the limiting inner ring.

[0052] The convex load-bearing component includes a load-bearing retaining ring 210, which is formed at the end of the convex joint end tube. Its axis forms a 45° angle with the axis of the convex joint end tube, and its inner edge protrudes toward the inside of the convex joint end tube to form a threading opening. The interior of the convex joint end tube can be connected with the outside through the threading opening, and its outer edge protrudes toward the outside of the convex joint end tube. The end face of the limiting outer ring can be engaged with the outer edge of the load-bearing retaining ring, and the limiting outer ring is used to axially position the load-bearing retaining ring.

[0053] The inner diameter matching component includes a matching inner ring 221 and a matching flange 222. The matching inner ring is formed on the inner edge of the load-bearing retaining ring, extends along the circumference of the load-bearing retaining ring, and protrudes axially toward the outside of the load-bearing retaining ring. Its diameter is smaller than the diameter of the limiting inner ring and can extend into the limiting inner ring. The matching flange is formed on the outer wall of the matching inner ring, extends along the circumference of the matching inner ring, and protrudes radially toward the outside of the matching inner ring. Its diameter is larger than the diameter of the limiting flange. When the matching inner ring extends into the limiting inner ring, the matching flange and the limiting flange abut against each other to perform axial positioning on the matching inner ring and the limiting inner ring.

[0054] In this embodiment, the limiting inner ring is made of elastic material, and is divided into a plurality of limiting claws by expanding and contracting the gap. The limiting flange and the matching flange both have an arc-shaped outer wall structure. When the matching inner ring moves along its axial direction, the matching flange applies pressure to each limiting claw to deflect it outward. When the matching flange enters the inner side of the limiting claw, the limiting claw returns to its original position. At this time, the limiting flange abuts against the matching flange to play an axial positioning role.

[0055] The circumferential matching component includes a matching block 230, which is formed on the load-bearing retaining ring and extends radially along the load-bearing retaining ring. Its end protrudes to the outside of the load-bearing retaining ring and is adapted to the shape of the positioning slot. It can extend into the positioning slot to perform circumferential positioning of the limiting outer ring and the load-bearing retaining ring.

[0056] In this embodiment, a bearing boss is provided in the middle part of the bearing retaining ring, which protrudes outward along the axial direction of the bearing retaining ring, and its diameter is smaller than the diameter of the limiting outer ring, so that the end face of the limiting outer ring can still be engaged with the outer edge of the bearing retaining ring, and the matching block is formed on the bearing boss, making it easier to engage with the positioning groove.

[0057] In this embodiment, the end of the matching card block has an arc-shaped outer convex surface, and the inner wall of the positioning groove has an arc-shaped inner concave surface, so that the matching card block can be easily inserted into the positioning notch or removed from the positioning notch.

[0058] like Figures 9-11 As shown, the adapter for the cable sleeve proposed by the present invention includes the above-mentioned matching assembly, and also includes a first locking end 300 and a second locking end 400. The first locking end is installed on the concave engagement end tube, and the concave engagement end tube can be connected to the sleeve body through the first locking end. The second locking end is installed on the convex engagement end tube, and the convex engagement end tube can be connected to the sleeve body through the second locking end. By adjusting the angle between the concave engagement end tube and the convex engagement end tube, and positioning through the positioning groove and the matching card block, the adapter can achieve a variety of angle states.
