Description

Technical Field

[0001] The invention relates to the technical field of sports equipment, in particular to a counting rope skipping handle with automatic unidirectional counting function. Background Art

[0002] The two handles of the counting skipping rope in the prior art are respectively a counting handle and an ordinary handle, and the counting range is 000-999. Before skipping, the user must determine which hand holds the counting handle (such as the right hand) to ensure that the counting is forward in the order of 001, 002, 003 when skipping. If the other hand (such as the left hand) is used to hold the counting handle for skipping, the counting sequence is 999, 998, 997, resulting in reverse counting. It often happens that the user finds out that the counting is reversed after skipping, causing the user to lose the counting information. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a counting rope skipping handle with automatic unidirectional counting function, which does not need to distinguish between a counting handle and an ordinary handle when skipping rope, and the counter rotates forward in the same direction in sequence no matter from which direction the skipping rope is swung.

[0004] The technical solution of the present invention is to provide an automatic unidirectional counting function counting rope skipping handle with the following structure, including a shell, in which a rotating head and a counter are arranged; also including a bidirectional ratchet shaft, a first gear and a second gear, the first gear and the second gear are rotatably connected between the rotating head and the counter, the first gear is close to the rotating head, the second gear is close to the counter and the two are circumferentially limited, the bidirectional ratchet shaft is connected between the first gear and the second gear and only meshes with one of the gears and rotates synchronously; the bidirectional ratchet shaft is circumferentially limited with the rotating head; a gear reversing mechanism is connected to the first gear and the second gear; when the rotating head rotates in one direction, the bidirectional ratchet shaft meshes with the first gear and rotates synchronously, the first gear meshes with the second gear through the gear reversing mechanism, and the second gear synchronously drives the counter; when the rotating head rotates in the opposite direction, the bidirectional ratchet shaft meshes with the second gear and rotates synchronously.

[0005] One end of the bidirectional ratchet shaft is provided with a first connecting shaft extending outward along the axis and a first ratchet tooth arranged on the end surface, the first connecting shaft passes through the first gear and is embedded in the center hole of the rotating head, the first gear is provided with a first ratchet groove matching the first ratchet tooth, and the first ratchet tooth drives the first gear to rotate circumferentially in one direction; the other end of the bidirectional ratchet shaft is provided with a second connecting shaft extending outward along the axis and a second ratchet tooth arranged on the end surface, the second connecting shaft is embedded in the hole of the second gear, the second gear is provided with a second ratchet groove matching the second ratchet tooth, and the second ratchet tooth drives the second gear to rotate circumferentially in one direction.

[0006] The outer walls of the first gear and the second gear are bevel gears and are symmetrically distributed on the left and right. The first gear and the second gear are coaxially arranged. The gear reversing mechanism is a third gear. The third gear is a bevel gear and is meshed with the bevel gears on the outer walls of the first gear and the second gear at the same time. A rotating shaft is provided at the tail end of the third gear and is installed on the housing.

[0007] The outer side walls of the first gear and the second gear are the first spur gear, and the gear reversing mechanism includes a second spur gear and a third spur gear, the second spur gear and the third spur gear are meshed with each other and both ends are rotatably connected in a fixed seat in the shell, the second spur gear is meshed with the first spur gear on the first gear, and the third spur gear is meshed with the first spur gear of the second gear, and the first gear drives the second gear to rotate through the second spur gear and the third spur gear.

A convex tooth is provided on the turntable of the counter, and the turntable of the counter is movably embedded in the inner hole of the second gear. The convex tooth abuts against the block and the two rotate synchronously.

[0009] The second gears 6 all drive the counter 3 in the same direction.

[0010] After adopting the above structure, the technology of the present invention has the following advantages compared with the prior art: since the rotating head rotates in one direction, the bidirectional ratchet shaft meshes with the first gear and rotates synchronously, the first gear meshes with the second gear through the gear reversing mechanism, and the second gear drives the counter synchronously; the rotating head rotates in the opposite direction, the bidirectional ratchet shaft meshes with the second gear and rotates synchronously, that is, if the rotating head meshes with the first gear through the bidirectional ratchet shaft, the second gear is driven through 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, and the second gear drives the counter in both ways in the same direction, so that there is a counting handle and an ordinary handle, but the user does not need to distinguish between the counting handle and the ordinary handle when skipping rope, no matter which hand holds the counting handle, it can ensure that the skipping rope is counted in the order of 001, 002, 003. In other words, no matter from which direction the skipping rope is swung, the counter rotates in the order of 001, 002, 003. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figure 1-9 As shown, the automatic unidirectional counting function counting rope skipping handle of the present invention comprises a housing 1, wherein the housing 1 comprises an upper housing and a lower housing, and the upper housing is also provided with a counting reset button. A rotating head 2 and a counter 3 are provided in the housing 1. Two cylindrical bosses are provided at the bottom of the counter 3 module, and the bosses are inserted into the counter hole grooves of the lower housing, so that the counter 3 is installed on the lower housing 1.

[0023] The automatic unidirectional counting function counting rope skipping handle of the present invention also includes a bidirectional ratchet shaft 4, a first gear 5 and a second gear 6, the first gear 5 and the second gear 6 are rotatably connected between the rotating head 2 and the counter 3, the first gear 5 is close to the rotating head 2, the second gear 6 is close to the counter 3 and the two are circumferentially limited, the bidirectional ratchet shaft 4 is connected between the first gear 5 and the second gear 6 and only meshes with one of the gears and rotates synchronously; the bidirectional ratchet shaft 4 and the rotating head 2 rotate circumferentially, and the rotating head 2 rotates in one direction, then the bidirectional ratchet shaft 4 meshes with the first gear 5 and rotates synchronously, the first gear 5 meshes with the second gear 6 through the gear reversing mechanism, and the second gear 6 drives the counter 3 synchronously; the rotating head 2 rotates in the opposite direction, then the bidirectional ratchet shaft 4 meshes with the second gear 6 and rotates synchronously, and the second gear 6 drives the counter 3 in the same direction.

[0024] like Figure 8 and Fig. 9 As shown, one end of the bidirectional ratchet shaft 4 is provided with a first connecting shaft 4.1 extending outward along the axis and a first ratchet tooth 4.2 arranged on the end surface, the first connecting shaft 4.1 passes through the first gear 5 and is embedded in the center hole of the rotating head 2, the first gear 5 is provided with a first ratchet groove 5.1 matching the first ratchet tooth 4.2, and the first ratchet tooth 4.2 drives the first gear 5 to rotate circumferentially in one direction; the other end of the bidirectional ratchet shaft 4 is provided with a second connecting shaft 4.3 extending outward along the axis and a second ratchet tooth 4.4 arranged on the end surface, the second connecting shaft 4.3 is embedded in the hole of the second gear 6, the second gear 6 is provided with a second ratchet groove 6.1 matching the second ratchet tooth 4.4, and the second ratchet tooth 4.4 drives the second gear 6 to rotate circumferentially in one direction.

[0025] [like Figure 1-4 As shown, the outer wall of the first gear 5 and the second gear 6 is a bevel gear and the two are symmetrically distributed on the left and right. The first gear 5 and the second gear 6 are coaxially arranged. The gear reversing mechanism is a third gear 7, which is a bevel gear and meshes with the bevel gears on the outer wall of the first gear 5 and the second gear 6 at the same time. The tail end of the third gear 7 is provided with a rotating shaft and is installed on the housing 1. The third gear 7 is installed on the gear hole groove of the lower housing. The left shaft of the two-way ratchet shaft 4 passes through the first gear 5, the right shaft passes through the second gear 6, and the end of the left shaft is inserted into the rotating head 2. The first gear 5 and the second gear 6 are limited in the axial direction by the limiting ribs on the lower housing. At the same time, the two-way ratchet shaft 4 is clamped by the first gear 5 and the second gear 6, so the two-way ratchet shaft 4 is also limited in the axial direction. The first gear 5, the second gear 6, and the third gear 7 are bevel gears that mesh with each other.

[0026] The shell 1 includes an upper shell and a lower shell, and the upper shell and the lower shell are both provided with a first reinforcing rib 1.1 and a second reinforcing rib 1.2. The first reinforcing rib 1.1 is provided with a first through hole, and the rotating head 2 is movably embedded in the first through hole. The second reinforcing rib 1.2 is provided with a second through hole, and the extension shaft on the second gear 6 close to the counter 3 is movably embedded in the second through hole.

[0027] like Figure 5-7 As shown, the outer side walls of the first gear 5 and the second gear 6 are the first spur gears, and the gear reversing mechanism includes a second spur gear 8 and a third spur gear 9. The second spur gear 8 and the third spur gear 9 are meshed with each other and both ends are rotatably connected to a fixed seat 10 in the housing 1. The second spur gear 8 is meshed with the first spur gear on the first gear 5, and the third spur gear 9 is meshed with the first spur gear of the second gear 6. The first gear 5 drives the second gear 6 to rotate through the second spur gear 8 and the third spur gear 9.

[0028] An inner hole is provided at one end of the second gear 6 close to the counter 3, and radially distributed blocks 11 are provided in the inner hole. A convex tooth 12 is provided on the turntable of the counter 3, and the turntable of the counter 3 is movably embedded in the inner hole of the second gear 6. The convex tooth 12 abuts against the block 11 and the two rotate synchronously.

[0029] Working principle: When the user swings the skipping rope, the rotating head 2 rotates with the swing of the rope, and the rotating head 2 is connected to the bidirectional ratchet shaft 4 in the phase-changing module, so the rotation direction and speed of the bidirectional ratchet shaft 4 and the rotating head 2 are the same.

[0030] The first case: when the user holds the handle with his right hand and the rotating head rotates clockwise (clockwise from left to right in the figure), the ratchet teeth at the left end of the two-way ratchet shaft 4 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 at 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. Through the transmission of the third gear 7, the second gear 6 will rotate counterclockwise. The second gear 6 drives the counter dial 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 dial, thereby realizing the forward counting of the counter (001, 002, 003...).

[0031] The second situation: when the user holds the handle with his left hand and the rotating head rotates counterclockwise, the ratchet teeth at 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 ratchet teeth at the left end of the two-way ratchet shaft slip with the ratchet groove of the first gear 5), and the second gear 6 directly drives the counter to count forward.

[0032] As described above, no matter which hand the user holds the counting handle, or whether the skipping rope is swung forward or backward, there will be no reverse erroneous counting (999, 998, 997...).
