[0002] Strictly speaking, freestyle is not a swimming style, but a competition event in competitive swimming. Its competition rules have almost no restrictions on swimming styles. Crawl has a reasonable structure, low resistance, and a uniform and fast speed. It is the most labor-saving and fastest swimming style. Therefore, people often use crawl, a swimming style with low resistance and high speed, in such competitions that have almost no restrictions on swimming styles. Therefore, freestyle and crawl are usually regarded as the same now.

[0003] The invention patent with patent application publication number CN107998636A discloses a freestyle training device, including a bottom panel, a front support frame and a rear support frame for supporting the bottom panel, a hand part, a leg part, and a head and chest part; the arc foot pad at the bottom of the rotating board cooperates with the roller on the upper surface of the car board to realize the rotation of the body when changing arms while paddling; the two ropes wound around the upper and lower pulleys connect the slider and the car board, so that the hand paddling action and the chest turning action as well as the action of pushing the body forward when paddling are well coordinated. After half a paddling cycle, the return process is automatically realized by the elastic stopper at the end of the bottom panel and the telescopic spring connecting the front and rear parts. This invention enables a wide range of freestyle enthusiasts or trainers to get rid of the limitations of the sports venue, and can practice swimming postures and strength training on land. To a certain extent, it overcomes the confusion of beginners in the process of freestyle learning and exploration or the fear of underwater movement of water-phobic people, and improves the efficiency of learning.

[0004] However, the freestyle land training device uses various mechanical structures to train the legs and arms, but cannot simulate the ups and downs produced during swimming. It is relatively mechanical, resulting in unsatisfactory training effects. Therefore, a freestyle land training device is now proposed. Summary of the invention

[0054] As attached Figure 1 , Figure 2 and Figure 8 As shown, each side panel 7 is provided with a card slot 12, and a side slot 13 is provided on one side of the card slot 12. The card slot 12 is used to card-connect the bottom end of the hand-held mechanism 8. The card slot 12 can be card-connected with the bottom end of the hand-held mechanism 8. The card slot 12 is exposed at the card-connecting part of the hand-held mechanism 8 through the side slot 13, which is convenient for locking the sliding position of the hand-held mechanism 8.

[0055] As attached Figure 4 and Figure 6 As shown, the isolation box 2 includes a box body 201 , and a groove and a sleeve groove are respectively provided at the upper and lower ends of the box body 201 , and the sleeve groove is sleeved on the top of the magnetic box 1 .

[0056] Two slide rails 202 are welded in the groove and are parallel to each other.

[0057] Two nitrogen springs 203 are installed on both sides of the inner wall of the groove and are connected to the two ends of the bottom of the suspension plate 3.

[0058] As attached Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the suspension board 3 includes a magnetic board 301 , and the bottom end of the magnetic board 301 has the same magnetic pole as the opposite side of the magnetic suspension assembly 11 .

[0059] Two suspension grooves 302 are each disposed at the bottom end of the magnetic plate 301 and are respectively sleeved on the slide rails 202 .

[0060] The prone plate 303 is installed on the top of the magnetic plate 301, and the top of the prone plate 303 is smooth.

[0061] When the magnetic plate 301 is subjected to the repulsive force of the magnetic levitation component 11, it is suspended and lifted on the slide rail 202. When the prone plate 303 is subjected to the force, it will rise and fall or swing in the direction of the force. During the swinging process, the nitrogen springs 203 on both sides will buffer the swinging force. At the same time, the magnetic plate 301 is always on the slide rail 202 and in a suspended state. Among them, the magnetic levitation component 11 is an existing magnetic levitation technology.

[0062] As attached Figure 1 , Figure 2 , Figure 8 and Fig. 9 As shown, the hand-held mechanism 8 includes a support plate 801 , a clamping block is welded on the bottom end of the support plate 801 , and the clamping block is slidably engaged in the clamping slot 12 .

[0063] The first locking button 802 is inserted into the side groove 13 and is spirally connected to one side of the clamping block.

[0064] The vertical groove 803 is opened in the middle of the top of the support plate 801.

[0065] The connecting rod 804 is inserted into the vertical groove 803 .

[0066] The turntable 805 is movably mounted on one end of the connecting rod 804 and has a sliding groove 15 on the other side relative to the supporting plate 801 .

[0067] The second locking button 806 is screwed on the other end of the connecting rod 804 , and one side of the second locking button 806 is connected to the supporting plate 801 .

[0068] When adjusting the position of the glove 14 according to the trainee's body shape, push the support plate 801 so that the block at the bottom moves in the slot 12. After moving to the appropriate position, lock the first locking button 802 to fix the position of the support plate 801. Then, move the connecting rod 804 up and down in the vertical slot 803, so that the turntable 805 moves up and down, so that the glove 14 is at an appropriate height. Then, rotate the second locking button 806 to fix the height position of the turntable 805. Then, according to the trainee's own arm span, move the support rod 1601 in the slide slot 15, so that the circular swing position of the glove 14 is adjusted on the turntable 805, and the position of the glove 14 is fixed by locking the third locking button 1603.

[0069] As attached Figure 1 , Figure 2 and Fig.11As shown, the foot connection mechanism 10 includes two brackets 1001 , and each bracket 1001 is welded to both sides of the top end of the rear plate 9 .

[0070] Crossbar 1002 , which is installed at the top between two brackets 1001 .

[0071] Two elastic ropes 1003 , one end of each elastic rope 1003 is bolted to the cross bar 1002 .

[0072] Two straps 1004 are respectively tied to the other end of the two elastic ropes 1003 .

[0073] When the trainee is doing swimming training and his legs are swinging, the straps 1004 are tied to the trainee's ankles. During the swinging process, tension is generated on the two elastic ropes 1003 at the bottom of the horizontal bar 1002. The elastic ropes 1003 generate a pull back force on the trainee due to the elastic effect, thereby simulating the water resistance of the trainee's legs in the water.

[0074] As attached Fig. 9 and Fig.10 As shown, the adjustment assembly 16 includes a support rod 1601 , and the support rod 1601 is inserted into the slide groove 15 .

[0075] The chuck 1602 is welded to one end of the support rod 1601 and is slidably engaged in the slide groove 15 .

[0076] The third locking button 1603 is screwed onto the support rod 1601 , and one side of the third locking button 1603 is pressed onto the slide groove 15 .

[0077] The insertion rod 1604 is movably connected to the other end of the support rod 1601, and the other end of the insertion rod 1604 is installed with a glove 14.

[0078] When the trainee swings his arms, the trainee inserts both hands into the gloves 14 respectively, and then performs swimming training. During the swinging process, the gloves 14 swing along with the arms, causing the turntable 805 to rotate, thereby reflecting the state of the arms swinging in the water.

[0079] As attached Figure 5 As shown, the isolation box 2 and the suspension board 3 are both made of plastic material, and a silicone pad is attached to the top of the suspension board 3.

[0080] As attached Figure 4 As shown, the nitrogen spring 203 is composed of two plastic clamping tubes that are slidably clamped, and nitrogen is filled in the internal communication grooves of the two plastic clamping tubes to form the nitrogen spring 203.

[0081] The working principle of the present invention is as follows: when a trainee is doing freestyle swimming training, the trainee lies on the floating board 3, with the chin of the head placed on the headrest 6 supported by the elastic rod 5, and then adjusts the positions of the gloves 14 on both sides according to the trainee's arm span. During the adjustment, the support plate 801 can slide in the card slot 12, so that the position of the gloves 14 can move forward and backward on both sides of the trainee, so that the gloves 14 can be adjusted to the appropriate position on the side of the trainee, and then the position of the adjustment component 16 can be slid and adjusted in the slide slot 15, so that when the trainee performs the action of simulating manual paddling, it can be in line with the trainee's arm span. After the position of the gloves 14 is adjusted, the two straps 1004 on the foot connection mechanism 10 are tied to the trainee's ankles respectively;

[0082] After the trainer is combined with the trainer, the magnetic suspension assembly 11 in the magnetic box 1 is connected to the power supply, so that the suspension board 3 at the top floats to support the trainer. The trainer starts training and performs swimming movements. During the training process of the trainer, due to the swinging of the arms and legs, the suspension board 3 is subjected to the irregular pressure of the trainer and produces ups and downs. During the ups and downs, the trainer's ups and downs are simulated. In the process of ups and downs, the suspension board 3 produces pressure on the nitrogen spring 203, and the nitrogen spring 203 automatically rebounds the suspension board 3 to reset the suspension board 3. At the same time, when the trainer's feet swing, the elastic rope 1003 is stretched and contracted to simulate the resistance of the trainer's legs to the trainer's legs when the trainer swings his legs in the water. As the trainer's movements are irregular, the more the suspension board 3 shakes. The trainer can adjust his own movements and adjust the ups and downs of the suspension board 3, thereby standardizing the trainer's movements and helping the trainer find his own relatively labor-saving movements, so as to improve his own competitive level through training.

[0083] The present invention can be used by trainees of different body shapes, and the fixed position of the arms can be adjusted according to the arm length of the trainees, so that external constraints can be reduced during training. In addition, combined with the suspended support of the prone board 303, the ups and downs of swimming can be realistically simulated, thereby improving the training effect.

[0084] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection. "upper", "lower", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may change;
