[0002] At present, many users in the market require that the skipping rope has a two-way counting function, that is, no matter whether the user jumps forward or backward, the number of skips can be recorded. In the prior art, many skipping ropes with two-way counting functions generally adopt ratchet mechanisms, which will generate continuous "tatta" noises during operation, affecting the user experience. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a two-way counting transmission assembly, which has the same transmission direction when driven forward or backward, can be applied to a skipping rope to provide a two-way counting function, does not include a ratchet mechanism, and can basically achieve silence during the driving and transmission process.

[0004] The technical solution of the present invention is to provide a two-way counting transmission assembly, including a first-stage bevel gear, a first-stage transmission member, a reversing bevel gear, a second-stage bevel gear, a second-stage transmission member, a counter turntable, and a transmission block; the reversing bevel gear meshes with both the first-stage bevel gear and the second-stage bevel gear, and the first-stage bevel gear drives the second-stage bevel gear in the reverse direction through the reversing bevel gear; the first-stage bevel gear is connected to the first-stage transmission member for co-directional transmission; the second-stage bevel gear is connected to the second-stage transmission member for co-directional transmission; the transmission block is rotatably arranged on the counter turntable, and the counter turntable limits the maximum rotation angle of the transmission block; the first-stage transmission member and the second-stage transmission member are respectively located on both sides of the counter turntable and can both cooperate with the transmission block to drive the counter turntable; when the first-stage bevel gear rotates forward, the first-stage transmission member and the second-stage transmission member can jointly drive the transmission block to rotate towards the first-stage transmission member side until the transmission block avoids the second-stage transmission member and the first-stage transmission member can push the transmission block to drive the counter turntable to rotate forward; when the first-stage bevel gear rotates in the reverse direction, the first-stage transmission member and the second-stage transmission member can jointly drive the transmission block to rotate towards the second-stage transmission member side until the transmission block avoids the first-stage transmission member and the second-stage transmission member can push the transmission block to drive the counter turntable to rotate forward.

[0005] Compared with the prior art, the two-way counting transmission component of the present invention has the following advantages: when the first-stage bevel gear rotates forward, the first-stage transmission member rotates forward, the second-stage bevel gear and the second-stage transmission member rotate in the reverse direction, and the first-stage transmission member and the second-stage transmission member can jointly drive the transmission block to rotate towards the first-stage transmission member until the transmission block is limited by the counter turntable when it rotates to the maximum rotation angle. At this time, the transmission block avoids the second-stage transmission member, so the second-stage transmission member can no longer drive the transmission block to rotate, while the first-stage transmission member can push the transmission block to drive the counter turntable to rotate forward; when the first-stage bevel gear rotates in the reverse direction, the first-stage transmission member rotates in the reverse direction, the second-stage bevel gear and the second-stage transmission member rotate forward, and the first-stage transmission member and the second-stage transmission member can jointly drive the transmission block to rotate towards the second-stage transmission member until the transmission block is limited by the counter turntable when it rotates to the maximum rotation angle. At this time, the transmission block avoids the first-stage transmission member, and the first-stage transmission member can no longer drive the transmission block to rotate, while the second-stage transmission member can push the transmission block to drive the counter turntable to rotate forward; thus, regardless of whether the first-stage bevel gear rotates forward or in the reverse direction, the counter turntable can rotate forward. Applying the two-way counting transmission component of the present invention to a skipping rope, swinging the rope to drive the first-stage bevel gear, whether it is a forward jump or a reverse jump, the counter turntable can drive the counter and the transmission direction remains unchanged, achieving the function of two-way counting; in addition, the two-way counting transmission component does not include a ratchet structure and can basically achieve silence during the transmission process.

[0006] Preferably, a transmission block gap is provided on the counter turntable, and the transmission block is arranged in the transmission block gap and is pivotally connected to the counter turntable; a primary transmission bar and a secondary transmission bar are provided on the transmission block, and the primary transmission bar and the secondary transmission bar are respectively located on both sides of the counter turntable, and the sizes of the primary transmission bar and the secondary transmission bar cannot pass through the transmission block gap; when the primary bevel gear rotates forward, the primary transmission member can push the primary transmission bar, and the secondary transmission member can push the secondary transmission bar to make the transmission block rotate to one side of the primary transmission member, until the secondary transmission bar avoids the secondary transmission member and the primary transmission member can push the primary transmission bar to drive the counter turntable to rotate forward; when the primary bevel gear rotates reversely, the primary transmission member can push the primary transmission bar, and the secondary transmission member can push the secondary transmission bar to make the transmission block rotate to one side of the secondary transmission member, until the primary transmission bar avoids the primary transmission member and the secondary transmission member can push the secondary transmission bar to drive the counter turntable to rotate forward. With this structure, a primary transmission bar and a secondary transmission bar are arranged on the transmission block, and the primary transmission member drives the transmission block to rotate by pushing the primary transmission bar, and the secondary transmission bar drives the transmission block to rotate by pushing the secondary transmission bar; when the transmission block rotates to the point where the primary transmission bar avoids the primary transmission member, the primary transmission member can no longer drive the transmission block to rotate, and after the transmission block is limited by the counter turntable, the secondary transmission member can push the secondary transmission bar to drive the counter turntable to rotate forward; when the transmission block rotates to the point where the secondary transmission bar avoids the secondary transmission member, the secondary transmission member can no longer drive the transmission block to rotate, and after the transmission block is limited by the counter turntable, the primary transmission member can push the primary transmission bar to drive the counter turntable to rotate forward; the transmission structure is simple and the production and assembly are convenient.

[0044] When using the two-way counting skipping rope of the present invention for backward skipping, the rope connecting member 1 rotates backward as the rope swings backward, and drives the first-stage bevel gear 2 to rotate backward as well. At this time, the first-stage transmission member 6 rotates backward, while the second-stage bevel gear 4 and the second-stage transmission member 5 rotate forward. The first-stage transmission rib 6-2 can push the first-stage transmission bar 9-1, and the second-stage transmission rib 5-1 can push the second-stage transmission bar 9-2 to make the transmission block 9 rotate towards the second-stage transmission member 5 until the first-stage transmission bar 9-1 abuts against the relative blocking surface 7-11. At this time, the first-stage transmission bar 9-1 avoids the first-stage transmission rib 6-2, and the second-stage transmission rib 5-1 can continue to push the second-stage transmission bar 9-2, so that the second-stage transmission bar 9-2 drives the counter turntable 7 to rotate forward, that is, the second-stage transmission member 5 can push the transmission block to drive the counter turntable 7 to rotate forward, and the counter turntable 7 drives the counter shaft 10-1 to rotate forward to make the counter 10 count.

[0045] That is, no matter whether the user skips forward or backward, the counter can accurately count; in addition, the two-way counting transmission component of the present invention does not include a ratchet structure, and can basically achieve silence during the transmission to the counter turntable.

[0046] The above are only specific embodiments of the present invention, and are not used to limit the scope of implementation of the present invention; if the present invention is modified or equivalently replaced without departing from the spirit and scope of the present invention, it should be covered by the protection scope of the claims of the present invention.
