[0004] To achieve the above-mentioned purpose, the technical solution provided by the utility model is: a skipping rope with adjustable length, which includes a rope, a rope collection box is provided at both ends of the rope, a handle is installed on the rope collection box, an opening on one side of the rope collection box is formed with an installation port, a box cover is installed at the installation port, a rotating shaft is movably installed at the center of the bottom of the inner cavity of the rope collection box, a rope body through hole penetrating inside and outside is provided on the rope collection box at the end away from the handle, the end of the rope passes through the rope body through hole and is connected to the rotating shaft, an adjustment handle is provided on the top of the rotating shaft, and an adjustment handle through hole is provided at the center of the box cover, and the adjustment handle through hole cooperates with the adjustment handle.

[0005] A hinge seat is installed on the top of the rotating shaft, one end of the adjusting handle is movably hinged on the hinge seat through the hinge shaft, and the other end of the adjusting handle forms a knob end. The box cover on one side of the perforated side of the adjusting handle is provided with a concave mounting groove, which cooperates with the knob end of the adjusting handle.

[0006] The box cover is installed on the rope collecting box through threads.

[0007] A connecting shaft is horizontally installed at the lower part of one side of the rotating shaft, and a mounting sleeve is connected to the end of the rope. The mounting sleeve is mounted on the connecting shaft, and a limiting shaft is fixed at the outer end of the connecting shaft. The mounted mounting sleeve is limited by the limiting shaft.

[0008] After the utility model adopts the above scheme, the length of the rope can be adjusted according to the user's requirements on the length of the rope. When the rope is too long and needs to be shortened, the knob end of the adjusting handle is buckled out of the installation slot, and then the adjusting handle is rotated. The adjusting handle drives the rotating shaft to rotate, and the rotating shaft drives the rope to be wound through the connecting shaft, thereby shortening the rope. When the rope is adjusted to an appropriate length, the knob end of the adjusting handle is clamped in the installation slot again. When the rope is too short and needs to be lengthened, the knob end of the adjusting handle is buckled out of the installation slot, and then the rope outside the rope collection box is pulled to make the rope wound on the rotating shaft come back. When the rope is adjusted to an appropriate length, the knob end of the adjusting handle is clamped in the installation slot again. After adopting the above scheme, the utility model has a reasonable structure and good use effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In the description of this patent, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "set" should be understood in a broad sense, for example, it can be fixedly connected or set, or it can be detachably connected or set, or connected or set in one piece. For ordinary technicians in this field, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0015] The present invention is further described below in conjunction with all the accompanying drawings. The preferred embodiments of the present invention are as follows: Figure 1 To Attachment Figure 3 The length-adjustable skipping rope described in this embodiment includes a rope 1, a rope collection box 2 is provided at both ends of the rope 1, a handle 3 is installed on the rope collection box 2, an installation port is formed at one side of the rope collection box 2, a box cover 4 is installed at the installation port, and the box cover 4 is installed on the rope collection box 2 through a thread, a rotating shaft 5 is movably installed at the center of the bottom of the inner cavity of the rope collection box 2, a rope body through hole 6 penetrating inside and outside is provided on the rope collection box 2 at the end away from the handle 3, a connecting shaft 11 is horizontally installed at the lower part of one side of the rotating shaft 5, the end of the rope 1 passes through the rope body through hole 6 and is connected to the installation sleeve 13, and the installation sleeve 13 It is mounted on the connecting shaft 11, and a limiting shaft 12 is fixed on the outer end of the connecting shaft 11. The mounted installation sleeve 13 is limited by the limiting shaft 12. An adjusting handle 7 is provided on the top of the rotating shaft 5, and an adjusting handle through-hole 8 is provided at the center of the box cover 4. The adjusting handle through-hole 8 cooperates with the adjusting handle 7. A hinge seat 9 is installed on the top of the rotating shaft 5. One end of the adjusting handle 7 is movably hinged to the hinge seat 9 through a hinge shaft, and the other end of the adjusting handle 7 forms a knob end.
