Description

Technical Field

[0001] The present invention relates to the technical field of training equipment, in particular to a land training device for water sports. Background Art

[0002] As a water sport that carries a thousand-year-old folk culture and competitive spirit, dragon boat rowing's charm lies not only in the teamwork interwoven with drum beats and calls, but also in the precise control of paddling rhythm and body balance as the boat cuts through the water, amidst the turbulence of waves and the impact of water currents. This explosive power output under dynamic balance is the core characteristic that distinguishes dragon boating from other land-based team sports. However, due to factors such as site conditions in natural waters, weather changes, and safety management, professional dragon boat teams' daily training has become increasingly dependent on land-based simulation equipment. Among these, the dragon boat ergometer, such as the prior art publication number CN212235919U, has become an important tool for improving athletes' physical fitness and technique by fundamentally recreating paddling movements and resistance.

[0003] At present, mainstream dragon boat ergometers are mostly based on fixed platforms and can only reproduce the forward and backward force trajectory when paddling, but cannot simulate the left and right swing of a real dragon boat when sailing on the water due to factors such as the difference in the depth of the unilateral paddle blade entering the water and the lateral impact of the water flow. This makes it difficult for athletes to train their core stability and lateral muscle control when dealing with the tilt of the hull during land training, as well as the on-the-spot adaptability to adjust the paddling angle in dynamic balance.

[0004] Secondly, dragon boat racing is a collective sport based on teamwork, and the consistency of multiple people's movements is crucial. However, existing ergometers are only for single-person training and cannot achieve the linkage of multiple people's movements, which makes it difficult for the team to coordinate during land training, and ultimately leads to a serious disconnect between training results and actual combat needs.

Side plates 164 are fixed on both sides of the end of the swing rod 16 close to the fixed rod 15. The swing rod 16 is rotatably connected to the fixed rod 15. Specifically, a groove 151 is provided at one end of the fixed rod 15 close to the swing rod 16. A rotating shaft 161 is fixed at one end of the swing rod 16 close to the fixed rod 15. The rotating shaft 161 is provided inside the groove 151 and is rotatably connected to the inner wall of the groove 151. A torsion spring 161 is provided on the outer wall of the rotating shaft 161. 162, a fixed block 19 is provided at one end of the swing link 16 away from the fixed link 15, and the end of the rotating shaft 161 away from the fixed link 15 is rotatably connected to the fixed block 19 via the rotating shaft 2 163, a support leg 17 is provided on the outer side of the end of the swing link 16 away from the fixed link 15, the fixed block 19 is fixed to the support leg 17, and the swing link 16 is rotatably connected to the support leg 17, a seat cushion 18 is fixed to the top of the end of the swing link 16 away from the fixed link 15, and pedals 113 are fixed on both sides of the support leg 17.

[0047] When the swing rod 16 does not rotate, the fixed rod 15 and the rotating shaft 161 are fixed by a latch to fix the fixed rod 15 and the swing rod 16 so that the person can perform fixed paddling training.

[0048] Next, a driving assembly 2 is provided on both sides of the fixed rod 15, which is used to drive the swing rod 16 to swing to simulate the swing of the dragon boat on the water surface; specifically, the driving assembly 2 includes a threaded barrel 21, which is installed on the outer wall of the fixed rod 15 through a bearing seat, and the internal thread of the threaded barrel 21 is connected to a threaded rod 22, one end of the threaded rod 22 extends out of one end of the threaded barrel 21, and a telescopic rod 23 is fixed to one end of the threaded rod 22, and an inclined plate 24 is fixed to the end of the telescopic rod 23 away from the threaded rod 22, and the inclined plate 24 is close to the side of the fixed rod 15 and fits with the outer wall of the fixed rod 15, which is used to limit the rotational movement of the telescopic rod 23 and the threaded rod 22, so that the threaded barrel 21 drives the threaded rod 22 to move laterally when the threaded barrel 21 rotates.

[0049] The other end of the threaded barrel 21 is provided with a shell 25, and the shell 25 is fixed to the outer wall of the fixed rod 15. A flip cover 28 is hinged at the bottom of the shell 25 away from the fixed rod 15. An upper pulley 26 and a lower pulley 27 are arranged in the shell 25. The upper pulley 26 is rotatably connected to the inner wall of the shell 25, and the lower pulley 27 is rotatably connected to the inner wall of the flip cover 28. The traction rope 14 passes between the upper pulley 26 and the lower pulley 27, and the upper pulley 26 is in transmission connection with the end of the threaded barrel 21 close to the shell 25. Figure 3 and Figure 4 As shown, the transmission structure between the upper pulley 26 and the end of the threaded barrel 21 close to the housing 25 includes but is not limited to a bevel gear set transmission connection.

[0050] This embodiment is suitable for single-person training:

[0051] During single-person fixed training, a pin is inserted between the fixed rod 15 and the rotating shaft 161 to fix the fixed rod 15 and the swing rod 16. Then the person sits on the seat 18, one foot steps on the pedal 110, the other foot steps on the pedal 113, and holds the dragon boat paddle 13 to perform paddling movements. The movement of the dragon boat paddle 13 pulls the wind resistance device 11 connected to its axis through the traction rope 14 to rotate, providing wind resistance and facilitating personnel training.

[0052] During single-person swing training, the latch between the fixed rod 15 and the rotating shaft 161 is pulled out, the flip cover 28 is opened, and the traction rope 14 is placed on the upper pulley 26 of the housing 25, and then the flip cover 28 is closed. At this time, the traction rope 14 is between the upper pulley 26 and the lower pulley 27. Then the person sits on the cushion 18, and when holding the dragon boat paddle 13 to do paddling movements, the traction rope 14 stretches to drive the upper pulley 26 and the lower pulley 27 to rotate. The rotation of the upper pulley 26 drives the threaded cylinder 21 to rotate, thereby driving the threaded rod 22 to move, and then drives the inclined plate 24 to move in the direction close to the side plate 164 through the telescopic rod 23. When the inclined surface of the inclined plate 24 contacts the side plate 164, the inclined plate 24 continues to move to drive The movable side plate 164 moves upward, thereby driving the swing arm 16 and the rotating shaft 161 to rotate, and at the same time the torsion spring 162 twists; when the traction rope 14 contracts, the upper pulley 26 is driven to reverse, thereby separating the inclined plate 24 from the side plate 164, and the swing arm 16 and the side plate 164 are reset under the elastic force of the torsion spring 162, so that when the personnel row the dragon boat paddle 13 back and forth, the swing arm 16 swings back and forth to drive the personnel to swing, realizing the simulation of the swinging of a real dragon boat when it is sailing on the water due to the difference in the depth of the single-side paddle blade entering the water, the lateral impact of the water flow and other factors, so as to train the personnel to cope with the core stability and lateral muscle control when the hull tilts, and the on-the-spot adaptability of adjusting the paddling angle in dynamic balance.

[0053] Then, by adjusting the length of the telescopic rod 23, the movement distance of the inclined plate 24 relative to the side plate 164 can be adjusted, thereby adjusting the movement height of the side plate 164, and then adjusting the swing amplitude of the swing rod 16, which is convenient for different people to perform different swing intensity training and has a wide range of applications.

[0054] Moreover, in this embodiment, there are two groups of driving components 2. When the person adjusts the paddling direction, that is, whether the person is paddling on the left or the right, the swing rod 16 can be driven to swing to simulate the swing of the dragon boat on the water.

[0055] Example 2: Figure 6-Figure 7 As shown, in this embodiment, a secondary training assembly 3 is provided at the end of the swinging rod 16 away from the fixed rod 15. Each set of secondary training assemblies 3 is provided with a second dragon boat paddle 4 on one side, facilitating teamwork training. Specifically, the secondary training assembly 3 includes a swinging plate 31 and a fixed plate 32 provided at one end of the swinging plate 31. The fixed plate 32 has a mounting slot 33 defined at the end near the swinging plate 31. A third rotating shaft 34 is fixed to the end of the swinging plate 31 near the fixed plate 32. The third rotating shaft 34 is disposed within the mounting slot 33 and extends from the end of the fixed plate 32 away from the swinging plate 31. The swinging plate 31 is rotatably connected to the fixed plate 32 via the third rotating shaft 34. A second torsion spring 35 is provided on the outer wall of the third rotating shaft 34. The second torsion spring 35 is disposed within the mounting slot 33.

[0056] When the swinging board 31 does not rotate, the swinging board 31 and the fixed board 32 are fixed by a latch, so that multiple people can perform fixed paddling training.

[0057] A seat cushion 2 311 is fixed to the top of the end of the swing plate 31 away from the fixed plate 32, and a support leg 4 310 is provided on the outside of the end of the swing plate 31 away from the fixed plate 32. A fixed block 2 36 is fixed to one side of the support leg 4 310, and the fixed block 2 36 is provided at the end of the swing plate 31 away from the fixed plate 32. The swing plate 31 is rotatably connected to the support leg 4 310, and the end of the swing plate 31 away from the fixed plate 32 is rotatably connected to the fixed block 2 36 through a rotating shaft 4 37. A pedal 2 313 is fixed on both sides of the support leg 4 310.

[0058] Two connecting plates 38 are fixed to the outer wall of one end of the fixed plate 32 away from the swinging plate 31, a pedal 2 312 is provided at the top of the swinging plate 31, and a support leg 3 39 is fixed to the bottom end of the fixed plate 32. Two movable wheels are fixed on the support leg 3 39. Lifting the rotating shaft 4 37 facilitates moving the auxiliary training component 3 through the two movable wheels on the support leg 3 39.

[0059] This embodiment is suitable for multi-person collaborative training:

[0060] When two people are training, a set of auxiliary training components 3 can be installed with the dragon boat training component 1. Specifically, the third shaft 34 is inserted into the second shaft 163, and the connecting plate 38 is installed on the outer wall of the fixing block 19. The third shaft 34 and the second shaft 163, and the connecting plate 38 and the fixing block 19 are fixed by bolts. Figure 11 and Figure 12 shown.

[0061] When multiple people are training, multiple groups of auxiliary training components 3 can be installed with the dragon boat training component 1. Specifically, after one group of auxiliary training components 3 is installed with the dragon boat training component 1, the third rotating shaft 34 of one group of auxiliary training components 3 is inserted into the fourth rotating shaft 37 of another group of auxiliary training components 3, and the connecting plate 38 of one group of auxiliary training components 3 is installed on the outer wall of the second fixed block 36 of the other group of auxiliary training components 3. The third rotating shaft 34 and the fourth rotating shaft 37, as well as the connecting plate 38 and the second fixed block 36 are fixed by bolts. Figure 13 shown.

[0062] After the installation is completed, when conducting fixed training with multiple people, a pin is inserted between the fixed rod 15 and the rotating shaft 161 to fix the fixed rod 15 and the swing rod 16, and a pin is inserted between the swing plate 31 and the fixed plate 32 to fix the swing plate 31 and the fixed plate 32. Then, multiple people sit on the seat cushion 18 and the seat cushion 2 311 respectively, one foot can be stepped on the pedal 1 110 or the pedal 2 312, and the other foot can be stepped on the pedal board 1 113 or the pedal board 2 313. Then, the dragon boat paddle 1 13 and the dragon boat paddle 2 4, and the two adjacent dragon boat paddles 2 4 are connected by the connecting rope 6. Then, multiple people slide the dragon boat paddle 13 and the dragon boat paddle 2 4 respectively. The movement of the dragon boat paddle 13 is pulled by the traction rope 14 to rotate the wind resistance 11 connected to its axis to provide wind resistance. At the same time, people can sense the movements of other dragon boat paddles through the connecting rope 6, so as to train the consistency of multiple people's movements, improve team coordination, effectively enhance team tacit understanding and collaborative reaction speed, and lay the foundation for the tactical execution of collective projects.

[0063] When multiple people are in swinging training, the pin between the fixed rod 15 and the rotating shaft 161 is pulled out, the pin between the swing plate 31 and the fixed plate 32 is pulled out, the flip cover 28 is opened and the traction rope 14 is placed between the upper pulley 26 and the lower pulley 27. When the first person rows the dragon boat paddle 13 to drive the swing rod 16 to swing, the swing rod 16 drives the swing plate 31 to swing through the rotating shaft 34. At the same time, the rotating shaft 4 37 on one group of auxiliary training components 3 drives the rotating shaft 3 34 of another group of auxiliary training components 3 to swing, thereby achieving the swing rod 16 and the swing plates 31 on multiple groups of auxiliary training components 3 to swing, so as to drive multiple people to swing synchronously, and the swing amplitude is adjustable, so as to simulate the swinging of a real dragon boat when it is sailing on the water due to the difference in the water entry depth of one side paddle blade, the lateral impact of the water flow and other factors, so as to collaboratively train multiple people to cope with the core stability and lateral muscle control when the hull tilts, and the on-the-spot adaptability of adjusting the paddling angle in dynamic balance.

[0064] Example 3: Figures 8-10 As shown, protective components 5 are provided on both sides of seat cushion 1 18 and both sides of seat cushion 2 311. The protective components 5 include a fixed slide 51 and a lifting plate 52 slidably arranged in the fixed slide 51. The fixed slide 51 and the lifting plate 52 are fixed by bolts to facilitate adjustment of the height of the protective component 5.

[0065] The fixed slide plate 51 of the protective component 5 at the seat cushion 1 18 is fixed on the pedal 1 113 , and the fixed slide plate 51 of the protective component 5 at the seat cushion 2 311 is fixed on the pedal 2 313 .

[0066] Before training, the height of the protective component 5 is lowered. After the person sits on the seat cushion 1 18 or the seat cushion 2 311, the lifting plate 52 is moved upward to adjust the height of the protective component 5 to protect the person on both sides, greatly reducing the probability of the person falling during swing training and improving safety.
