Description

Technical Field

[0001] The present application relates to the field of rowing machines, and in particular to a rowing machine for training simulation. Background Art

[0002] Rowing machine is also known as rowing machine, rowing machine, rowing machine, ergometer, land rowing machine, indoor rowing machine. Rowing machine is a machine used for training purposes to simulate water rowing. Indoor rowing competition has become a professional competition. Indoor rowing machine is also commonly called ergometer (commonly known as erg or ERGO in foreign countries), which measures the power consumed by athletes during exercise.

[0003] The rowing machines currently in use cannot enable trainees to experience the shaking feeling when rowing on the water, which makes it impossible for trainees to truly get the feeling of training on the water. Although the existing rowing machines can achieve the purpose of fitness, for some rowing athletes or rowing enthusiasts, it is particularly important to always maintain the feeling and state of rowing on the water. Therefore, some places will set up some rowing training halls, and set up longer pools in the training halls to facilitate rowing training personnel to conduct training. However, for some beginners, if the beginners are allowed to practice directly on the water, due to the lack of training of the beginners, it is easy for the kayak to capsize and cause the beginners to fall into the water, making it inconvenient for the beginners to practice. At the same time, the beginners occupying the venue or falling into the water may easily affect the training of professional trainees. Based on the above problems, it is necessary to design a rowing machine that can simulate the shaking generated when rowing on the water. Summary of the invention

[0024] In summary, this application includes the following beneficial technical effects:

[0025] 1. The training simulation rowing machine utilizes a compression spring, a turntable, and a chassis to simulate the state of the rowing machine on the water, so that beginners can quickly adapt to the instability of rowing on the water through training, and can quickly get used to the shaking feeling of rowing on the water, so that beginners can adapt to the feeling of rowing on the water through simulation training, so that beginners can quickly perform water training.

[0026] 2. By arranging the first ball joint seat and the second ball joint seat on the turntable and the base respectively, the stability of the base on the compression spring is enhanced, so that when the trainee slides on the rowing machine, the base is not prone to shaking or tilting at a large angle. At the same time, the risk of the compression spring breaking when the trainee is training on the rowing machine is also reduced, the service life of the compression spring is extended, and the risk of injury to the trainee during training is reduced.

[0027] 3. By arranging a buffer spring in the connecting tube, the buffer spring can provide a buffer force to the connecting rod when the trainee is training on the rowing machine. When the trainee is training on the rowing machine, due to its heavy weight, if the connecting rod and the connecting tube are arranged as one body, the bending moment it bears is large, making it easy to break. However, the two are arranged separately, and a buffer spring is placed in the connecting tube, so that the buffer spring provides a reverse buffer force to the connecting rod, which not only reduces the risk of the connecting rod breaking, but also well protects the safety of the trainee during training and extends the service life of the entire training simulation rowing machine.

DETAILED DESCRIPTION

[0033] The present application is further described in detail below in conjunction with the accompanying drawings.

[0034] The embodiment of the present application discloses a rowing machine for training simulation.

[0035] Reference Figure 1 The training simulation rowing machine includes a chassis 1, a turntable 2 and a rowing machine 3.

[0036] The chassis 1 is placed on the ground or fixed to the ground with anchor bolts. The turntable 2 is rotatably connected to the chassis 1 , and the rowing machine 3 is installed on the turntable 2 .

[0037] Reference Figure 1 and Figure 2 The rowing machine 3 includes a base 31 , a water tank 32 , a rotating shaft 33 , paddles 34 , a pull rope 35 , an elastic rope 36 and a sliding seat 37 .

[0038] Four compression springs 41 are evenly distributed on the bottom of the base 31. The four compression springs 41 are respectively arranged at the bottom of the four end corners of the base 31. The top of the compression spring 41 is welded to the bottom of the base 31, and the bottom of the compression spring 41 is welded to the turntable 2. The four compression springs 41 are used to support the base 31 to achieve the shaking of the rowing machine 3 on the turntable 2, which is convenient for beginners to experience the instability caused by rowing on water. At the same time, in order to improve the stability of the connection between the compression spring 41 and the turntable 2 and the base 31, mounting plates 411 are fixed at both ends of the compression spring 41, and then the mounting plates 411 at both ends of the compression spring 41 are fixed to the turntable 2 and the base 31 by bolt connection.

[0039] Reference Figure 1 and Figure 2 The water tank 32 is fixed on the base 31. A water inlet pipe is provided on the top of the water tank 32. The top of the water inlet pipe is a water inlet. A water inlet ball valve is installed on the water inlet pipe. A water outlet pipe is provided at the bottom of the water tank 32. The bottom of the water outlet pipe is a water outlet. A water outlet ball valve is installed on the water outlet pipe.

[0040] The rotating shaft 33 is passed through the water tank 32, and both ends of the rotating shaft 33 pass through the water tank 32, and the contact ends of the rotating shaft 33 and the water tank 32 need to be sealed. A plurality of paddles 34 are fixed to the part of the rotating shaft 33 located in the water tank 32. When the rotating shaft 33 rotates, the paddles 34 drive the water in the water tank 32 to rotate, thereby achieving the problem of resistance caused by imitating paddling. The base 31 is provided with three layers, upper, middle and lower, so that two upper and lower cavities are formed on the base 31. The water tank 32 is placed in the lower cavity on the base 31, and the two ends of the rotating shaft 33 are respectively rotatably connected to the middle and lower layers of the base 31, and the top of the rotating shaft 33 extends out of the middle layer of the base 31 and extends into the upper cavity of the base 31.

[0041] Reference Figure 1 and Figure 2 One end of the pull rope 35 is fixed to the protruding end of the rotating shaft 33 , and the other end of the pull rope 35 is a free end for the training personnel to pull. A pull rod 351 is fixed to the free end of the pull rope 35 .

[0042] One end of the elastic rope 36 is fixed to the middle layer of the base 31, and the other end of the elastic rope 36 is fixed to the rotating shaft 33, and the elastic rope 36 is wound around the rotating shaft 33. The winding direction of the elastic rope 36 on the rotating shaft 33 is opposite to the winding direction of the pull rope 35 on the rotating shaft 33. In this way, after the trainee pulls the pull rope 35 to make the rotating shaft 33 drive the paddle 34 to stir the water in the water tank 32, the elastic rope 36, under the action of its own elastic force, drives the rotating shaft 33 to reverse so that the rotating shaft 33 drives the paddle 34 to return to its original position, thereby resetting the rotating shaft 33 and the paddle 34.

[0043] Reference Figure 1 and Figure 2 The base 31 is also provided with two parallel slide rails 311, and the sliding seat 37 is slidably connected to the two slide rails 311. A limit baffle is provided at the edge of the sliding seat 37 to prevent the sliding seat 37 from falling off the two slide rails 311. The base 31 is also provided with a pedal part for the trainer to step on. An anti-skid pad 312 is fixedly attached to the pedal part, and a strap 313 for fixing the trainer's shoes is provided on the anti-skid pad 312.

[0044] A fixed pulley 38 is also fixed to the base 31 , and the fixed pulley 38 is located on the upper layer of the base 31 . The pull rope 35 is wound around the fixed pulley 38 so that the pull rope 35 can be transferred from the upper cavity of the base 31 to the top of the base 31 , thereby facilitating the training personnel to pull the pull rope 35 .

[0045] Reference Figure 1 and Figure 2Two fixing columns 39 are also provided on the base 31, and the two fixing columns 39 are located above the footrest part. The pull rope 35 is located between the two fixing columns 39, and the pull rod 351 is located on the side of the fixing column 39 away from the water tank 32, so that when the elastic rope 36 pulls the rotating shaft 33 to rotate, the pull rope 35 is prevented from being entangled on the rotating shaft 33.

[0046] During training, the trainee adds water into the water tank 32 and closes the water inlet ball valve. The trainee then steps on the pedal part and uses the straps 313 to fix the shoes. The trainee pushes forward to make the legs almost straight. At the same time, the arm pulls the pull rope 35 backward and bends the arm. The pull rope 35 drives the rotating shaft 33 and the paddle blade 34 to rotate. The paddle blade 34 stirs the water in the water tank 32. The sliding seat 37 slides backward on the slide rail 311. After the trainee's legs are almost straight, the legs and arms are relaxed. The elastic rope 36 pulls the rotating shaft 33 to rotate. At the same time, the pull rope 35 is wound around the rotating shaft 33. The staff then returns to the initial position on the rowing machine 3, resets, and then pulls the pull rope 35 again to train. This cycle is repeated to achieve the purpose of simulating rowing.

[0047] Further, refer to Figure 1 and Figure 3 A first ball joint seat 42 is provided on the top of the turntable 2. The bottom of the first ball joint seat 42 is fixed to the turntable 2 by bolt connection. There are four first ball joint seats 42. The four first ball joint seats 42 are respectively located inside the four compression springs 41. A connecting tube 43 is provided on the first ball joint seat 42. The connecting tube 43 is hollow inside. The side of the connecting tube 43 away from the turntable 2 is open. The open end of the connecting tube 43 is a free end. The end of the connecting tube 43 close to the turntable 2 is solid and connected to a first articulated ball. This end of the connecting tube 43 is a fixed end. The first articulated ball is installed in the first ball joint seat 42.

[0048] Reference Figure 3 and Figure 4 The bottom of the base 31 is provided with a second ball joint seat 44, the bottom of the second ball joint seat 44 is fixed to the base 31 by bolt connection, and the number of the second ball joint seats 44 is also four, and the four second ball joint seats 44 are respectively located inside the four compression springs 41. The second ball joint seat 44 is spherically jointed with a connecting rod 45, which is a solid rod. One end of the connecting rod 45 is fixed to the second hinge ball, and this end of the connecting rod 45 is a fixed end. The other end of the connecting tube 43 is a free end, and the diameter of the connecting rod 45 is slightly smaller than the inner diameter of the connecting tube 43, so that the free end of the connecting rod 45 can be inserted into the free end of the connecting tube 43.

[0049] During installation, the connecting rod 45 is inserted into the connecting tube 43. In order to prevent the connecting rod 45 from hitting the bottom of the connecting tube 43 when it moves downward in the connecting tube 43, thereby causing injuries to the trainee, a buffer spring 46 is installed inside the connecting tube 43. The bottom of the connecting rod 45 abuts against the buffer spring 46.

[0050] Further, refer to Figure 3 and Figure 4 When the trainee is training on the rowing machine 3, if the compression spring 41 and the mounting plate 411 are broken, the connecting rod 45 may be easily disengaged from the connecting tube 43, and the trainee may be injured. In order to avoid the above problem, a limiting ring 47 is fixed on the free end of the opening of the connecting tube 43, and the inner diameter of the limiting ring 47 is smaller than the inner diameter of the connecting tube 43. A limiting plate 48 is fixed on the free end of the connecting rod 45, and the diameter of the limiting plate 48 is slightly smaller than the diameter of the connecting tube 43. The diameter of the connecting rod 45 is slightly smaller than the inner diameter of the limiting plate 48. During installation, the limiting ring 47 is firstly passed through the connecting rod 45, and then the limiting plate 48 is welded to the free end of the connecting rod 45, and then the limiting plate 48 is installed in the connecting tube 43, and finally the limiting ring 47 is welded and fixed to the connecting tube 43.

[0051] The working process of this embodiment:

[0052] The trainee sits on the sliding seat 37 and pulls the pull rod 351 on the pull rope 35, and uses the pull rope 35 to drive the rotating shaft 33 and the paddle 34 to rotate, and the paddle 34 stirs the water in the water tank 32 to simulate the resistance of rowing on water; while the trainee is training on the rowing machine 3, since the bottom of the rowing machine 3 is supported by four springs, four compression springs 41 are used to simulate the shaking feeling caused by rowing on water, and the connection between the connecting rod 45 and the connecting pipe 43 is used to avoid the excessive separation of the compression spring 41 so that the base 31 is separated from the turntable 2. At the same time, a buffer spring is installed inside the connecting pipe 43 to buffer the connecting rod 45, so as to reduce the direct impact of the base 31 on the connecting pipe 43 during the downward process, thereby reducing the possibility of injury to the trainee, and the turntable 2 is rotatably connected to the chassis 1 to simulate the instability caused by rowing on water or the situation where the boat spins on the water.

[0053] The working principle of this embodiment:

[0054] The training simulation rowing machine 3 is provided with four compression springs 41 between the base 31 on which the rowing machine 3 is installed and the turntable 2 rotatably connected to the chassis 1, so that when the trainee or the beginner is training on the rowing machine 3, the rowing machine 3 has extremely strong instability. The compression spring 41 can be compressed and the turntable 2 can be rotated on the chassis 1, and the two are combined to simulate the instability of rowing on water, so that the trainee or the beginner can better and faster adapt to the shaking and instability in the process of rowing on water, so that the beginner can quickly master simple rowing skills and quickly adapt to the instability caused by the left and right shaking during the rowing process. At the same time, a first ball joint seat 42, a connecting rod 45, a connecting tube 43 and a second ball joint seat 44 are connected between the base 31 and the turntable 2, which increases the stability of the connection between the base 31 and the turntable 2, reduces the risk of breakage of the compression spring 41 due to the repeated shaking of the base 31 during the training of the trainees or beginners, and improves the safety of the trainees or beginners during the training. At the same time, a buffer spring 46 is placed in the connecting tube 43, so that the squeezing force of the connecting rod 45 on the connecting tube 43 is released through the buffer spring 46, reducing the risk of breakage or squeezing deformation of the connecting rod 45 and the connecting tube 43, protecting the personal safety of the trainees or beginners during the training, and extending the service life of the training simulation rowing machine 3. The training simulation rowing machine 3 simulates the instability caused by the left and right swaying during rowing on the water, and simulates the instability of the left and right swaying during rowing on the water more realistically, so that beginners can use the instability caused by the left and right swaying during rowing on the water better and faster, thereby reducing the risk of the beginners falling into the water due to the boat capsizing or swaying during rowing on the water.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
