Description

Automatic one-way counting function counting skipping rope handle

technical field

The invention relates to the technical field of sports equipment, in particular to a rope skip handle with automatic one-way counting function.

Background technique

The two handles of the counting skipping rope in the prior art are a counting handle and a common handle respectively, and the counting interval is 000-999. Before skipping the rope, the user must determine which hand holds the counting handle (such as the right hand) to ensure that the The sequence of 001, 002, 003 is counted forward. If the other hand (such as the left hand) is used to hold the counting handle and skip the rope, the counting sequence will be 999, 998, 997, resulting in reverse counting. It is often the case that the user only finds that the counting is reversed after skipping the rope, causing the user to lose count information.

After adopting the above structure, compared with the prior art, the technology of the present invention has the following advantages: because the rotating head rotates in one direction, the bidirectional ratchet rotating shaft meshes with the first gear and rotates synchronously, and the first gear is changed by the gears. The direction mechanism meshes with the second gear, and the second gear drives the counter synchronously; the rotating head rotates in the opposite direction, then the bidirectional ratchet rotating shaft meshes with the second gear and rotates synchronously, that is, if the rotating head passes through the bidirectional ratchet rotating shaft and the first When one gear is engaged, the second gear is driven by the gear reversing mechanism, and the second gear drives the counter in a single direction. If the rotating head meshes with the second gear through the bidirectional ratchet shaft, the second gear drives the counter in a single direction. The gears all drive the counter in the same direction, so it is a counting handle and a common handle, but the user does not need to distinguish between the counting handle and the ordinary handle when skipping the rope. No matter which hand holds the counting handle, it can be guaranteed that the jump rope is 001, 002, 003. The sequence counts forward. In other words, no matter which direction the skipping rope is thrown, the counter will rotate forward in the order of 001,002,003.

Working principle: When the user swings the skipping rope, the rotating head rotates with the rope, and the rotating head is connected with the bidirectional ratchet shaft in the disguised module, so the rotation direction and speed of the bidirectional ratchet shaft and the rotating head are the same.

The first situation: when the user holds the handle with the right hand, the rotating head rotates clockwise (clockwise in the view from left to right in the figure), the ratchet teeth on the left end of the two-way ratchet shaft engage with the ratchet groove of the first gear 5 and Drive the first gear 5 to rotate clockwise (at this time, the ratchet teeth on the right end of the two-way ratchet shaft and the ratchet groove of the second gear 6 slip), and the first gear 5 drives the third gear 7 to rotate. The second gear 6 will rotate counterclockwise, and the second gear 6 will drive the counter turntable to rotate counterclockwise through the contact transmission between the inner teeth on the right side and the convex teeth on the left side of the counter turntable, so as to realize the forward counting of the counter (001, 002, 003...).

The second situation: when the user holds the handle with the left hand, the rotating head rotates counterclockwise, the ratchet teeth on the right end of the two-way ratchet shaft engage with the ratchet groove of the second gear 6 and drive the second gear 6 to rotate clockwise (at this time, the left end of the two-way ratchet shaft rotates clockwise). The ratchet teeth and the ratchet groove of the first gear 5 slip), and the second gear 6 directly drives the counter to count forward.

Above, no matter which hand the user holds the counting handle, or whether the skipping rope is thrown forward or backward, there will be no reverse error count (999, 998, 997...).
