Detailed Description
As shown in fig. 1, a rope skipping handle and rope body connecting piece comprises a first rotating piece 1, a second rotating piece 2 and a central rotating shaft 3.
The first rotating member 1 is a cylinder, one surface of the first rotating member connected with the second rotating member 2 is an inclined surface A, and an included angle between a plane perpendicular to the central axis of the first rotating member 1 and the inclined surface is alpha, wherein alpha is 10-35 degrees. The second rotating member 2 is a cylinder, one surface of the second rotating member which is connected with the first rotating member 1 is an inclined surface B, and an included angle between a plane which is perpendicular to the central axis of the second rotating member 2 and the inclined surface is beta, wherein beta is alpha. Bevel a is substantially the same shape as bevel B.
The first rotating member 1 is connected with the second rotating member 2 through a central rotating shaft 3, and after connection, an inclined plane A of the first rotating member 1 is connected with an inclined plane A of the second rotating member 2. After the connection, the first rotating member 1 and the second rotating member 2 can rotate relative to each other around the central rotating shaft 3.
The central rotation axis 3 is located at the center of the inclined plane a of the first rotation member 1 and the center of the inclined plane B of the second rotation member 2, and is perpendicular to the inclined plane a of the first rotation member 1 and the inclined plane B of the second rotation member 2. As shown in fig. 2, the central rotating shaft 3 is cylindrical, the side wall near the end is provided with an installation groove 3-1, one end of the central rotating shaft 3 is fixedly connected with the first rotating member 1 or the second rotating member 2, and the other end is connected with the second rotating member 2 or the first rotating member 1 through a clamp spring 3-2; or the two ends of the central rotating shaft 3 are respectively connected with the first rotating part 1 and the second rotating part 2 through clamp springs 3-2.
As shown in fig. 3, the first rotating member 1 is provided with a positioning protrusion 4 and a spring block 5 at an eccentric position on the inclined surface.
As shown in fig. 4 and 5, the second rotating member 2 has a circular groove 6 formed on the inclined surface thereof, and a tooth-shaped groove 7 formed at the bottom of the circular groove 6. The end surface of the tooth-shaped groove 7 is in a gear shape, and the circular groove 6 and the tooth-shaped groove 7 are arranged at the center of the inclined plane of the second rotating member 2; the edge of the bottom of the round groove 6 is provided with a limiting mechanism. The limiting mechanism can adopt the following two modes:
1. as shown in fig. 4, the limiting mechanism is a limiting bulge 8 arranged at the bottom edge of the circular groove 6;
2. as shown in fig. 5, the depth of the tooth-shaped groove 7 is partially smaller than that of the other parts, forming a limit step 9.
The positioning protrusion 4 is located at the edge of the circular groove 6 and is matched with the limiting protrusion 8 or the limiting step 9 in position to limit the maximum relative rotation angle of the first rotating member 1 and the second rotating member 2 to be 180 degrees.

When the first rotating piece 1 and the second rotating piece 2 rotate relatively, the elastic block 5 makes circular motion, the elastic block 5 reaches the tooth protrusion position of the tooth-shaped groove 7, and the tooth protrusion extrudes the elastic claw 5-1 to deform the elastic claw; the shape is recovered after the tooth is protruded. Therefore, the resistance of rotation is increased, and the rotation is not free and free. When the positioning bulge 4 reaches the position of the limit bulge 8 or the limit step 9, the rotation cannot be continued, and the relative rotation is just 180 degrees at the moment.
The skipping rope comprises a rope body and two handles, and at present, the rope body and the handles are directly connected. With this connection, the head of the string is connected to the first rotating member or the second rotating member, while the handle is connected to the second rotating member or the first rotating member. When the rope skipping handle is used, the connecting piece is rotated, when the central axes of the first rotating piece and the second rotating piece are consistent, the inclined plane included angle alpha of the first rotating piece is complementary with the inclined plane included angle beta of the second rotating piece, and at the moment, the whole rope skipping handle is a linear handle. After the rope skipping handle is rotated for 180 degrees, the included angle theta between the central axes of the first rotating piece and the second rotating piece is 180 degrees- (alpha + beta), and the whole rope skipping handle is a fold-line-shaped handle. The included angle theta of the fold lines is 110-160 degrees, which belongs to the application range. When α is 15 to 30 °, θ is 120 to 150 °, which is a relatively comfortable use range. According to the test, the included angle theta of the broken line body is about 135 degrees, which is more fit for the human body, therefore, alpha is 22.5 degrees, which is the best choice.
