[0026] The technical scheme in this embodiment will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1-5 As shown, a specific embodiment 1 of the utility model: a counting rope skipping handle, comprising a handle body 1, the handle body 1 having an accommodating space 11 therein, and a through hole 12 is provided at the center of one end face thereof, the through hole 12 is used for the rope skipping input shaft to pass through, the rope skipping input shaft is used to connect the rope skipping and can be transmitted to the counter inside the handle, the accommodating space 11 of the handle body 1 has an empty area A11a and an empty area B11b in the radial direction, the empty area A11a is used to accommodate the counting wheel group, and the empty area B11b is used to accommodate the carry wheel group, and a transmission mechanism 2 is also provided in the handle body 1, the transmission mechanism 2 is used to transmit the main axis of the rope skipping input shaft and the counting wheel group whose central axes are parallel and staggered.

[0028] Specifically, the transmission mechanism 2 is a slider coupling.

[0029] Specifically, the slider coupling is composed of two half couplings 21' and an intermediate disk 22'. The intermediate disk 22' and the two half couplings 21' are matched through a group of grooves 23' and convex teeth 24'. The convex teeth 24' on both sides are perpendicular to each other and slide in the corresponding radial grooves 23' to realize the connection of the two half couplings 21'. The two half couplings 21' are used to connect the input shaft of the skipping rope and the main shaft of the counting wheel group respectively. Specifically, the two half couplings 21' have grooves 23' on the end faces, and the intermediate disk 22' has convex teeth 24' on both sides. The convex teeth 24' are fixed or integrally arranged with the intermediate disk 22'. The convex teeth 24' on both sides of the intermediate disk 22' are perpendicular to each other and pass through the center; or the two half couplings 21' have convex teeth 24' on the end faces, and the intermediate disk 22' has grooves 23' on both sides; or the intermediate disk 22' has convex teeth 24' on one side and grooves 23' on the other side.

[0030] Specifically, the first half coupling 21a is coaxially connected to the skipping rope input shaft; the second half coupling 21b is coaxially connected to the main shaft of the counting wheel set.

[0031] Specifically, the first half coupling 21a has an axial hole 1 21a1 for inserting the input shaft of the skipping rope, and the second half coupling 21b has an axial hole 21b1 for inserting the main shaft of the counting wheel set. The handle body 1 also has a bracket 3, and the bracket 3 has a support opening 31. The second half coupling 21b also has a concave neck 21b2, and the neck 21b2 is axially positioned and clamped in the support opening 31 of the bracket 3, and the neck 21b2 can rotate in the support opening 31. When the neck 21b2 is installed in the support opening 31, since the neck 21b2 is concave, the wall edge of the support opening 31 is clamped into the annular notch 21b3 formed by the neck, and the wall edge of the support opening 31 will be blocked by the two side surfaces of the notch in the axial direction, thereby forming the axial positioning of the neck 21b2.

[0032] Specific working principle: The transmission mechanism 2 is used to transmit the skipping rope input shaft and the main shaft of the counting wheel group whose central axes are parallel and staggered.

[0033] When the skipping rope is used, the input shaft of the skipping rope is transmitted to the slider coupling, and then the slider coupling is transmitted to the main shaft of the counting wheel set. The slider coupling is a coupling commonly used in mechanical transmission. Its main function is to connect two shafts with different central axes, and keep the relative position and relative angle of the axes unchanged while transmitting power. The purpose of transmitting torque is achieved by connecting the protruding teeth 24' on both sides of the intermediate disk 22', which are distributed at 90 degrees relative to each other, and the grooves 23' on the two side half couplings 21'. Because the protruding teeth 24' can slide in the grooves 23', the relative displacement between the two shafts during installation and operation can be compensated.

[0034] It is not necessary to set the main axis of the counting wheel set to coincide with the central axis of the handle body, and because the central axis of the main axis of the counting wheel set can be set away from the central axis of the handle body 1, the empty area A11a can be set close to the side of the handle body 1, thereby reducing or removing the empty area B on the other side in the prior art. The diameter of the handle body can be reduced.

[0035] like Figure 6-8 As shown, another structure of a slider coupling in a counting rope skipping handle is as follows: the slider coupling is composed of two half-couplings 21" and an intermediate slider 22", the slider 22" is a square slider, and the intermediate slider 22" slides in the corresponding radial grooves 211" on the end faces of the half-couplings 21" on both sides thereof to achieve the connection of the two half-couplings 21", and the two half-couplings 21" are used to connect the input shaft of the rope skipping and the main shaft of the counting wheel set respectively. The groove 211" is formed between two convex strips 212" on the end face of the half-coupling 21", and the convex strip 212" is fixed or integrally arranged with the half-coupling 21".

[0036] Specifically, the first half coupling 21a is coaxially connected to the skipping rope input shaft, and the second half coupling 21b is coaxially connected to the main shaft of the counting wheel set. The second half coupling 21b also has a neck 21b2.

[0037] Specific embodiment 3 of the utility model: The transmission mechanism 2 in a counting skipping rope handle can also be a gear transmission group. The gear transmission group has: a driving gear for coaxially connecting the skipping rope input shaft, and a driven gear for coaxially connecting the counting wheel group main shaft, and the driving gear and the driven gear are directly or indirectly meshed. When only the driving gear and the driven gear are provided, the two gears are meshed side by side.

[0038] It should be noted that the descriptions of "first", "second", etc. in the present utility model are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. In the description of the present utility model, the meaning of "several" is at least two, such as two, three, etc., unless otherwise clearly and specifically limited.

[0039] In the description of the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "couple", "connect", and "fix" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
