Description

Technical Field

[0001] The present invention relates to the technical field of rope skipping, and in particular to a mechanical rope skipping counting structure and a mechanical counting rope skipping handle. Background Art

[0002] Rope skipping is a sport suitable for people of different age groups. It can be used indoors or outdoors with a skipping rope. However, there are two types of existing adjustment machines or skipping rope handles. One is a counting version that allows users to clearly know the number of jumps, and the other is an ordinary non-counting version. Users need to count by themselves. According to market research, the counting version of the skipping rope device is more in line with market demand, and most of them use the skipping rope handle for counting. However, the counting handle is divided into electronic and mechanical types. Among them, the mechanical type has a counting range of 000-999. Before skipping, the user must determine which hand holds the counting handle (such as the right hand) to ensure that the skipping is counted in the order of 001, 002, and 003. If the other hand (such as the left hand) is used to hold the counting handle for skipping, the counting order is 999, 998. , 997, resulting in reverse counting. Users often find that the counting is reversed after jumping rope, causing users to lose counting information. The electronic type requires the installation of a series of electrical components such as chips, circuit boards, sensors, batteries, etc. in the counting handle, which is relatively expensive and easily damaged after long-term use. Summary of the Invention

[0003] Purpose of the present invention: In order to overcome the defects of the prior art, the present invention provides a mechanical skipping rope counting structure, which drives the counter input end to always rotate in one direction through the transmission structure, and the transmission structure has a simple structure, which makes it more convenient to assemble, and the cost is relatively low, the stability is relatively good, and it is not easy to damage.

[0004] The present invention discloses a mechanical rope skipping counting structure, which is characterized by comprising:

[0005] Mounting seat;

[0006] Counter, used to record the number of rope skipping;

[0007] A rotating head is provided on the mounting base for rotation, and a driving gear is provided on the rotating head for synchronous rotation;

[0008] The pendulum block is swingably mounted on the mounting seat, a transmission shaft is rotatably provided on the pendulum block, a first transmission gear meshing with the driving gear is provided at a position corresponding to the driving gear, and a second transmission gear is provided on the transmission shaft;

[0009] A linkage gear is rotatably mounted on a mounting base and is linked to an input terminal of the counter;

[0010] A driven gear is rotatably mounted on a mounting seat and meshes with the linkage gear;

[0011] A magnetic member is provided on one of the pendulum block and the rotating head, and an adapter that can be magnetically matched with the magnetic member is provided on the other. When the magnetic member and the adapter are magnetically matched, the rotating head can drive the pendulum block to swing, thereby disengaging the second transmission gear from the engagement between the linkage gear and the driven gear, or disengaging the driven gear from the engagement between the linkage gear and the driven gear;

[0012] A blocking surface, which is used to limit the swing angle of the pendulum block;

[0013] The mounting seat is provided with a swing groove, the swing block is swingably arranged in the swing groove, and the blocking surface is formed by the inner wall of the swing groove.

[0014] By adopting the above technical solution, the mounting base can assemble the rotating head, the pendulum block and other components into one body, so that it is more convenient and stable when assembled into the handle. During use, the rotation of the rope will drive the rotating head to rotate. When the rotating head rotates in the forward direction, the magnetic part and the adapter will be relatively attracted when they are aligned, which can drive the pendulum block to swing to one side of the swing groove. When the pendulum block swings to against the inner wall of the swing groove, it will limit the swing of the pendulum block. At this time, the magnetic part will be separated from the adapter by the inertia force of the rotation of the rotating head, and the second transmission gear will mesh with the driven gear. At this time, because the driving gear will drive the first transmission gear to rotate in the opposite direction, the second transmission gear is reversed. Because the driven gear is meshed with the second transmission gear, the driven gear will rotate forward at this time, and because the driven gear is meshed with the linkage gear, the linkage gear It will reverse and drive the counter to count. When the rotating head rotates in the opposite direction, the magnetic part and the adapter will be relatively attracted when they are aligned, which can drive the pendulum block to swing to the other side of the swing groove. When the pendulum block swings to against the inner wall of the swing groove, it will limit the swing of the pendulum block. At this time, the magnetic part will be separated from the adapter by the inertial force of the rotation of the rotating head. At the same time, the second transmission gear is engaged with the linkage gear. At this time, because the active gear will drive the first transmission gear to rotate forward, the second transmission gear rotates forward, and then the linkage gear is engaged with the second transmission gear, so the linkage gear will rotate in the opposite direction to drive the counter to count. Regardless of whether the rotating head is rotated forward or reverse, it will drive the linkage gear to rotate in the opposite direction, and the counting will be more accurate, so that the user can get better results when using it. In addition, the structure is relatively simple and the cost is relatively low.

[0015] The present invention is further provided with an extension plate on the side of the mounting seat facing away from the counter, the extension plate is located on the outside of the pendulum block and is provided with a guide groove, the pendulum block is provided with a guide block adapted thereto, the guide block is rotatably arranged in the guide groove and can be abutted against the inner wall of the guide groove to form a movable limit of the pendulum block.

[0016] By adopting the above technical solution, the guide block and the guide groove can play a guiding role when the pendulum block swings, making it more stable when in use, and the guide block can also be against the inner wall of the guide groove, so that the pendulum block plays a limiting role when sliding axially along the transmission shaft, further improving stability.

[0017] The present invention is further configured as follows: the magnetic member and the adapter are both magnets, the adapter is arranged on the pendulum block and is arranged toward the rotating head, the magnetic member is arranged on the rotating head and rotates synchronously with the rotating head, and the adapter is located on the rotation track of the magnetic member.

[0018] By adopting the above technical solution, the magnets can be assembled by cutting grooves on the rotating head and the pendulum block, so that the entire head does not need to be made of iron material, which can reduce the relative production cost.

[0019] The present invention is further configured as follows: the swing groove is configured in an arc shape, and the arc center of the swing groove overlaps with the rotation center of the rotating head.

[0020] The above technical solution can better conform to the rotation trajectory of the rotating head, making it more stable when in use.

[0021] The present invention is further provided with: the linkage gear includes a first gear plate and a second gear plate, the first gear plate and the second gear plate are arranged in front and behind along the axial direction of the transmission shaft, the first gear plate is linked with the input end of the counter, and the second gear plate is engaged with the driven gear.

[0022] The above technical solution can facilitate the staggered installation of the input end of the counter and the driven gear, making it more convenient during assembly.

[0023] Another object of the present invention is to disclose a mechanical counting rope skipping handle, which includes a handle body, a rope skipping mechanical counting structure is arranged on the handle body, and an observation area for observing the count of the counter is also provided on the handle body.

[0024] By adopting the above technical solution, the handle can connect the rope to the rotating head, making it convenient for the user to view the counting situation.

[0025] A further configuration of the present invention is that the handle body includes an upper shell and a lower shell that are separately arranged and snap-connected. BRIEF DESCRIPTION OF THE DRAWINGS

For example, it can be a fixed connection, an integral connection, or a detachable connection; it can be the internal communication of two elements; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] The present invention discloses a mechanical counting skipping rope handle. In an embodiment of the present invention, the handle body 1 includes an upper shell 11 and a lower shell 12 which are split and snap-connected. The upper shell 11 and the lower shell 12 cooperate to form an assembly cavity. The assembly cavity has a built-in mounting seat 2, a counter 3 and a rotating head 4 (the counter 3 can be purchased directly on the market and will not be introduced in detail in this article. The mounting seat 2 can be mounted on the upper shell 11 or the lower shell 12 in a split manner, or it can be formed by injection molding the upper shell or the lower shell). The counter 3 is arranged on one side of the mounting seat 2; the rotating head 4 is rotatably arranged on the mounting seat 2, and the rotating head 4 is provided with a driving gear 41 which rotates synchronously with the mounting seat 2 (the rotating head 4 can be hinged to achieve rotation through a hinge shaft, or it can be provided with a shaft, and the shaft is directly rotatably arranged on the mounting seat 2); the mounting seat 2 is provided with a swinging groove 21, and a swing block 5 is swingably arranged on the swinging groove 21 (of course, the swing block 5 can be directly swingably arranged on the mounting seat 2, and then a guide groove is provided on the swing block 5. A guide rail is set on the mounting seat 2 to realize the swing of the pendulum block 5). A transmission shaft 51 is rotatably passed through the pendulum block 5. The transmission shaft 51 is provided with a first transmission gear 52 meshing with the driving gear 41 at a position corresponding to the driving gear 41, and a second transmission gear 53 is provided at the end of the transmission shaft 51 close to the counter 3; the inner wall of the end of the swing groove 21 is a limiting surface 211, which can limit the swing amplitude of the pendulum block 5, thereby preventing the second transmission gear 53 from swinging too much. A linkage gear 22 that cooperates with the input end of the counter 3 and a driven gear 23 that meshes with the linkage gear 22 are provided on the side of the mounting seat 2 close to the counter 3. The linkage gear 22 and the driven gear 23 are both rotatably set on the mounting seat 2; one of the pendulum block 5 and the rotating head 4 is provided with a magnetic component 42, and the other is provided with an adapter 54 that can be magnetically matched with the magnetic component 42. When the magnetic component 42 and the adapter 54 are magnetically matched, the rotating head 4 can drive the pendulum block 5 to swing, prompting the second transmission gear 53 to swing to mesh with the linkage gear 22 or with the driven gear 23.

[0040] By adopting the above technical solution, the mounting base 2 can assemble the rotating head 4, the pendulum block 5 and other components into one body, so that it is more convenient and stable when it is assembled into the handle. When in use, the rotation of the rope will drive the rotating head 4 to rotate. When the rotating head 4 rotates forward, when the magnetic element 42 and the adapter 54 are aligned, they will be relatively attracted, which can drive the pendulum block 5 to swing to one side of the swing groove 21. When the pendulum block 5 swings to the inner wall of the swing groove 21, it will limit the swing of the pendulum block 5. At this time, the inertia force of the rotation of the rotating head 4 The magnetic part 42 will separate from the adapter 54. At the same time, the second transmission gear 53 will mesh with the driven gear 23. At this time, because the driving gear 41 will drive the first transmission gear 52 to rotate in the opposite direction, the second transmission gear 53 will be reversed. Since the driven gear 23 is meshed with the second transmission gear 53, the driven gear 23 will rotate forward at this time. Since the driven gear 23 is meshed with the linkage gear 22, the linkage gear 22 will reverse and drive the counter 3 to count. When the rotating head 4 rotates in the opposite direction, when the magnetic part 42 is meshed with the adapter 5 When the first gear 53 is in the forward direction, the second gear 53 is engaged with the second gear 22.

[0041] An extension plate 6 is provided on the side of the mounting base 2 facing away from the counter 3. The extension plate 6 is located on the outside of the pendulum block 5 and is provided with a guide groove 61 (the extension plate 6 is most preferably arc-shaped, and the guide groove 61 is also arc-shaped, which will not affect the swing of the pendulum block 5). The pendulum block 5 is provided with a guide block 55 that is compatible with it. The guide block 55 is rotatably set in the guide groove 61 and can be abutted against the inner wall of the guide groove 61 to form a movable limit for the pendulum block 5. When the pendulum block 5 swings, the guide block 55 and the guide groove 61 can play a guiding role, making it more stable when in use, and the guide block 55 can also be abutted against the inner wall of the guide groove 61, so that the pendulum block 5 plays a limiting role when sliding axially along the transmission shaft 51, further improving stability.

[0042] The magnetic component 42 and the adapter 54 are both magnets. The adapter 54 is arranged on the pendulum block 5 and is arranged toward the rotating head 4. The magnetic component 42 is arranged on the rotating head 4 and rotates synchronously with it. The adapter 54 is located on the rotation track of the magnetic component 42. The magnets can be assembled by grooving on the rotating head 4 and the pendulum block 5, so that they do not need to be made of iron material as a whole, which can reduce the relative production cost. Of course, the magnetic component 42 can also be arranged on the rotating head 4, and the adapter 54 can be made of magnetic material (such as iron).

[0043] The swing groove 21 is arranged in an arc shape, and the arc center of the swing groove 21 overlaps with the rotation center of the rotating head 4, which can better conform to the rotation trajectory of the rotating head 4 and make it more stable when in use.

[0044] The linkage gear 22 includes a first gear disc 221 and a second gear disc 222. The first gear disc 221 and the second gear disc 222 are arranged in front and behind along the axial direction of the transmission shaft 51. The first gear disc 221 is linked to the input end of the counter 3, and the second gear disc 222 is engaged with the driven gear 23, which can facilitate the staggered installation of the input end of the counter 3 and the driven gear 23, making it more convenient during assembly.

[0045] The handle body 1 is also provided with an observation area 13 for observing the counter count. The observation area 13 can be a through hole to facilitate exposure of the display area of the counter 3. Of course, the observation area 13 can also be provided with a transparent cover to facilitate observation of the display area of the counter 3.
