Description

Technical Field

[0001] The invention relates to the technical field of sports training, in particular to an electric skipping rope for sports training. Background Art

[0002] Rope skipping is a sport game in which one or more people do various jumping movements on a ring-shaped rope. As an ancient folk entertainment activity of the Han nationality, rope skipping has been played during every festival since the Southern Song Dynasty, and every household has participated in competitions. Rope skipping is not only an entertainment activity, but regular rope skipping can also serve as a physical exercise and ensure people's health.

[0003] When trainees use skipping rope for training, since each person has a different height, the length of the rope required for skipping rope is also different. Manually swinging the rope consumes a lot of manpower. In the process of swinging the rope, the person jumping rope may be hit if he is not careful. At the same time, the skipping rope needs to be bent when it is stored after use for easy storage. There will be creases on the rope that has been bent for a long time, and it will be in a bent state when used again, which is not conducive to the use of trainees. The rope will frequently contact with the ground during use, and dust will accumulate on the surface of the rope. Not only is it unclean, but it may also affect the use of the rope.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present invention provides an electric skipping rope for sports training, which has the following beneficial effects:

[0018] 1. The electric skipping rope for sports training stores the rope through a drum. When skipping rope training is required, the rope is pulled at this time, and the drum will rotate accordingly. The rotation of the drum will prompt the second roller to move, so that the first roller will rotate through the drive belt. In this state, the first roller will synchronously drive the rotating block to rotate. When the rotating block and the driven member are in a meshing state, the rotating block will drive the driven member to move, and then pull the rectangular block to move, so that one group of positioning blocks fixedly connected to the rectangular block moves, thereby driving one group of card blocks to move in the groove opened inside the limit block. At this time, the moving rectangular block will cause another group of card blocks to move in the opposite direction through the rubber belt, so that the other group of card blocks squeezes the spring. When the rotating block is not engaged with the driven member, the rectangular block is not subjected to force at this time, and the spring in the compressed state will rebound, so that the other group of card blocks returns to the initial position, and then one group of card blocks is also restored to the initial position through the rubber belt. As the rope is pulled, the two groups of card blocks perform continuous reciprocating motion, thereby achieving the purpose of straightening the bent rope.

[0019] 2. The electric skipping rope for sports training is started by the staff by starting the external first motor and the third motor. The start of the first motor will drive the drum to start rotating, thereby winding the rope. During the winding process, the drum will drive the second roller, the transmission belt, and the first roller to move, and then the two groups of blocks will be continuously reciprocated through the rotating block, the follower, the rectangular block and the rubber belt. With the movement of the block, the positioning block and the clamping block will also move accordingly, and the dirt on the surface of the rope inside the clamping block will be cleaned. With the rotation of the drum, the telescopic part will also periodically extend and retract under the action of the third motor, and then the wedge block will reciprocate in the groove opened in the fixing part, so that the rope is evenly wound around the drum, thereby achieving the purpose of conveniently cleaning the dust on the rope and winding up the rope firmly.

[0020] 3. The electric skipping rope for sports training is started by a staff member by starting the external second motor. The rotating shaft will rotate under the action of the second motor, thereby driving the connecting member 1 and the connecting member 2 to swing with the rotating shaft as the rotation center. During the rotation, since the connecting member 2 is hinged to the columnar body, and the columnar body is clamped in the elliptical groove provided in the side plate, the connecting member 1 and the connecting member 2 will rotate with an elliptical rotation trajectory under the limitation of the groove provided on the side plate, so that the rope clamped in the limiting member will swing with an elliptical trajectory, thereby achieving the purpose of preventing the trainees from being injured due to the swinging amplitude of the rope during the rope swinging process.

[0035] The inside of the limit block 101 is connected with two groups of horizontally flush blocks 102. The blocks 102 are provided with small holes whose sizes match the rope 206. The sizes of the blocks 102 match the grooves provided inside the limit block 101. Under the joint action of the rectangular block 105, the positioning block 103 and the rubber belt 106, the two groups of blocks 102 make reciprocating motions in opposite directions inside the grooves provided inside the limit block 101, thereby straightening the rope 206 in a bent state.

[0036] The upper and lower ends of the clamping block 102 are fixedly connected to two symmetrical positioning blocks 103. The positioning blocks 103 are provided with grooves whose sizes match those of the clamping block 104. The positioning blocks 103 define the position of the clamping block 104. The positioning blocks 103 move under the action of the clamping block 102, thereby driving the position of the clamping block 104 to change.

[0037] One side of the positioning block 103 is hinged with two clamping blocks 104 facing each other. The size of the clamping block 104 is adapted to the groove provided on the positioning block 103. The initial position of the clamping block 104 is inclined at 45 degrees to the horizontal plane. The clamping block 104 reciprocates under the action of the positioning block 103 and the clamping block 102 to clean the dirt on the surface of the rope 206 in the reeled state.

[0038] A rectangular block 105 is fixedly connected to the bottom of one group of positioning blocks 103. The rectangular block 105 defines the position of the rubber belt 106. When the rectangular block 105 moves under the action of the follower 109, it will drive one group of card blocks 102 connected thereto to move, and will also make the other group of card blocks 102 move in the opposite direction through the rubber belt 106 to straighten the rope 206, or drive the positioning block 103 and the clamping block 104 connected to the two groups of card blocks 102 to clean the dirt on the surface of the rope 206 in the reeled state;

The two blocks 102 connected to the two ends of the rubber belt 106 move in opposite directions by turning the wheel 107.

[0040] A rotating wheel 107 is arranged on the inner side of the end of the rubber belt 106 away from the rectangular block 105. The rotating wheel 107 is hinged with the limit block 101. A groove whose size matches that of the rubber belt 106 is arranged on the outer side of the rotating wheel 107. The rotating wheel 107 limits the position of the rubber belt 106. Two symmetrical springs 108 are fixedly connected to one side of another set of limit blocks 101 close to the rotating wheel 107. The size of the spring 108 matches the distance between another set of card blocks 102 and the inner wall of the limit block 101. When the rotating block 110 is engaged with the follower 109, the spring 108 will be contracted by the pressure of the card block 102. When the rotating block 110 is not engaged with the follower 109, the spring 108 rebounds to restore the card block 102 to its initial position, and the cycle repeats.

[0041] A follower 109 is fixedly connected to the side of the rectangular block 105 away from the rubber belt 106. The follower 109 is clamped on the limit block 101. The follower 109 is provided with a plurality of cylinders whose spacing between each other matches the size of the groove provided on the rotating block 110. The outer size of the follower 109 matches the slide groove provided on the limit block 101. When the follower 109 is engaged with the rotating block 110, the follower 109 will drive the rectangular block 105 to move, and then the two clamping blocks 102 will move through the rectangular block 105 and the rubber belt 106 and other structures. When the rotating block 110 is not engaged with the follower 109, the follower 109 will return to the initial position under the rebound force of the spring 108, waiting to be engaged with the rotating block 110 again.

[0042] A rotating block 110 is provided at one end of the follower 109 away from the rubber belt 106. The rotating block 110 is hinged to the side plate 115. A half-circle size is provided on the outer side of the rotating block 110 to match the spacing between the cylinders provided on the follower 109. When the rotating block 110 is engaged with the follower 109, the rotating block 110 starts to rotate through the roller 111, thereby driving the follower 109 to move.

[0043] A roller 111 is fixedly connected to one side of the rotating block 110. A groove having a size matching that of the transmission belt 112 is provided on the outer side of the roller 111. The roller 111 rotates under the action of the transmission belt 112 and the roller 2 113, thereby driving the rotating block 110 to move.

[0045] The inner part of the transmission belt 112 away from the roller 111 is clamped with the second roller 113, and the outer side of the second roller 113 is provided with a groove whose size matches the transmission belt 112. The second roller 113 rotates under the action of the roller 114, thereby driving the transmission belt 112 and the roller 1 111 to move;

[0046] A drum 114 is fixedly connected to one side of the roller 2 113, and the drum 114 is connected to the power output shaft of the external first motor. The drum 114 stores the rope 206, and the rotation of the drum 114 will also drive the roller 2 113 to rotate. The drum 114 is hinged with a side plate 115 at one end away from the roller 2 113. An elliptical groove with a size matching the columnar body 204 is provided on the outer side of the side plate 115. The side plate 115 limits the positions of structures such as the limit block 101 and the drum 114, and also limits the movement trajectory of the connector 1 202 and the connector 2 203.

The outer side of the connecting piece 1 202 away from the rotating shaft 201 is sleeved with a connecting piece 203, and the connecting piece 203 is provided with a groove with a size adapted to the connecting piece 1 202. The connecting piece 203 rotates under the action of the rotating shaft 201 and the connecting piece 1 202, and is also affected by the elliptical grooves provided on the columnar body 204 and the side plate 115, so that the connecting piece 1 202 and the connecting piece 2 203 rotate in an elliptical motion trajectory;

[0052] Embodiment 3

[0053] See also Figure 1 , Figure 2 , Figure 5 , Figure 8 and Fig. 9, an electric skipping rope for sports training, comprising a fixing member 301, the fixing member 301 is fixedly connected to the side plate 115, a groove having a size matching that of a wedge block 302 is provided in the fixing member 301, and the fixing member 301 defines the position and movement trajectory of the wedge block 302;

[0054] A wedge block 302 is clamped inside the fixing member 301. The size of the wedge block 302 matches the groove on the fixing member 301. A through hole whose size matches the rope 206 is provided inside the wedge block 302. Under the action of the telescopic member 303, the wedge block 302 reciprocates horizontally inside the fixing member 301, and cooperates with the rotating drum 114 to store the rope 206 in an orderly manner.

[0055] A telescopic member 303 is fixedly connected to one side of the wedge block 302. The end of the telescopic member 303 away from the wedge block 302 is fixedly connected to the side plate 115. The telescopic member 303 is connected to the power output end of the external third motor. The telescopic member 303 is continuously extended or retracted under the action of the third motor, thereby driving the wedge block 302 to move inside the fixed member 301.

[0056] Working process and principle: please refer to Figures 1 to 10 , an electric skipping rope for sports training, wherein a rope 206 is stored by a drum 114. When skipping rope training is required, the rope 206 is pulled, and the drum 114 rotates accordingly. The rotation of the drum 114 causes the second roller 113 to move, thereby driving the transmission belt 112 to cause the first roller 111 to start rotating. In this state, the first roller 111 synchronously drives the rotating block 110 to rotate. When the rotating block 110 and the driven member 109 are in a meshing state, the rotating block 110 drives the driven member 109 to move, thereby pulling the rectangular block 105 to move, so that one group of positioning blocks 103 fixedly connected to the rectangular block 105 is moved. The moving rectangular block 105 moves in the groove of the limit block 101, and the moving rectangular block 105 makes the other group of blocks 102 move in the opposite direction through the rubber belt 106, so that the other group of blocks 102 squeeze the spring 108. When the rotating block 110 is not engaged with the follower 109, the rectangular block 105 is not subjected to force, and the spring 108 in the compressed state rebounds, so that the other group of blocks 102 returns to the initial position, and then the rubber belt 106 makes one group of blocks 102 return to the initial position. With the pulling of the rope 206, the two groups of blocks 102 perform continuous reciprocating motion.

[0057] The staff starts the external first motor and the third motor. The first motor starts to drive the drum 114 to start rotating, so that the rope 206 is wound. During the winding process, the drum 114 drives the second roller 113, the transmission belt 112, and the first roller 111 to move, and then the two groups of blocks 102 are made to perform continuous reciprocating motion through the rotating block 110, the driven member 109, the rectangular block 105, and the rubber belt 106. With the movement of the block 102, the positioning block 103 and the clamping block 104 will also move accordingly, and the dirt on the surface of the rope 206 inside the clamping block 104 will be cleaned. With the rotation of the drum 114, the telescopic member 303 will also perform periodic extension and retraction motion under the action of the third motor, so that the wedge block 302 reciprocates in the groove opened in the fixing member 301, so that the rope 206 is evenly wound around the drum 114;

[0058] When the staff starts the external second motor, the shaft 201 will rotate under the action of the second motor, thereby driving the connecting piece 1 202 and the connecting piece 203 to swing with the shaft 201 as the rotation center. During the rotation, since the connecting piece 203 is hinged with the columnar body 204, the columnar body 204 is clamped in the elliptical groove opened on the side plate 115. Therefore, the connecting piece 1 202 and the connecting piece 203 will rotate with an elliptical rotation trajectory under the limitation of the groove opened on the side plate 115, so that the rope 206 stuck in the limiting piece 205 swings with an elliptical trajectory.

[0059] In summary, the electric skipping rope for sports training stores the rope 206 through the drum 114. When skipping rope training is needed, the rope 206 is pulled, and the drum 114 will rotate accordingly. The rotation of the drum 114 will prompt the second roller 113 to move, so that the roller 111 starts to rotate through the drive belt 112. In this state, the roller 111 will synchronously drive the rotating block 110 to rotate. When the rotating block 110 and the driven member 109 are in a meshing state, the rotating block 110 will drive the driven member 109 to move, and then pull the rectangular block 105 to move, so that one group of positioning blocks 103 fixedly connected to the rectangular block 105 moves, thereby driving the A group of blocks 102 moves in the grooves provided inside the limit block 101. At this time, the moving rectangular block 105 will cause another group of blocks 102 to move in the opposite direction through the rubber belt 106, so that the other group of blocks 102 squeezes the spring 108. When the rotating block 110 is not engaged with the follower 109, the rectangular block 105 is not subjected to force, and the spring 108 in the compressed state will rebound, so that the other group of blocks 102 returns to the initial position, and then the rubber belt 106 also returns one group of blocks 102 to the initial position. As the rope 206 is pulled, the two groups of blocks 102 perform continuous reciprocating motion, thereby achieving the purpose of straightening the bent rope 206.

[0060] The staff starts the external first motor and the third motor. The start of the first motor will drive the drum 114 to start rotating, thereby winding the rope 206. During the winding process, the drum 114 will drive the roller 2 113, the transmission belt 112, and the roller 1 111 to move, and then the two groups of blocks 102 will be continuously reciprocated through the rotating block 110, the driven member 109, the rectangular block 105 and the rubber belt 106. With the movement of the block 102, the positioning block 103 and the clamping block 104 will also move accordingly, and the dirt on the surface of the rope 206 inside the clamping block 104 will be cleaned. With the rotation of the drum 114, the telescopic member 303 will also periodically extend and retract under the action of the third motor, so that the wedge block 302 will reciprocate in the groove opened in the fixing member 301, so that the rope 206 is evenly wound around the drum 114, thereby achieving the purpose of conveniently cleaning the dust on the rope 206 and firmly winding the rope 206.

[0061] When the staff starts the external second motor, the shaft 201 will rotate under the action of the second motor, thereby driving the connecting piece 1 202 and the connecting piece 203 to swing with the shaft 201 as the rotation center. During the rotation, since the connecting piece 203 is hinged with the column 204, the column 204 is clamped in the elliptical groove provided on the side plate 115. Therefore, the connecting piece 1 202 and the connecting piece 203 will rotate with an elliptical rotation trajectory under the limitation of the groove provided on the side plate 115, so that the rope 206 stuck in the limiting piece 205 swings in an elliptical trajectory, thereby achieving the purpose of preventing the trainees from being injured due to the swinging amplitude of the rope 206 during the rope swinging process.
