Description

Technical Field

[0001] The utility model relates to the technical field of swimming training equipment, in particular to a one-to-one simulation training device for freestyle swimming on land. Background Art

[0002] Freestyle is a competitive swimming event, and its competition rules have almost no restrictions on swimming postures; the crawl stroke has a reasonable structure, less resistance, and a uniform and fast speed. It is the most labor-saving and fastest swimming posture. In freestyle competitions, crawl stroke, a swimming posture with low resistance and fast speed, is often used. For some beginners, when practicing freestyle, they need to learn the movements and techniques. It is obviously not realistic to go into the water directly. They need to learn the correct swimming movements on land before they can go into the water with protective measures.

[0003] The body movements in freestyle swimming mainly include the arm stroke, the coordinated lateral movement of the torso and the kicking movement of the lower body. Since the arm stroke has a large amplitude and is an action that people tend to pay attention to, there are many devices that train the strength and posture of the arm stroke. These training devices ignore the torso movement and the kicking movement. Some training devices only train the upper limb strength, such as patent documents CN201721051702, 20170822. It is impossible to achieve all-round movement coordination training, and it is necessary to improve and transform it. Utility Model Content

[0045] The tension training device includes a folding groove limit baffle 22, a handle 18, a front support frame, a tension training steel cable, a weight tray and a guide steel cable 172, which are arranged on the crossbeam 121.

[0046] The front support frame includes a support frame A 11, a support frame B 12 and a top frame 13. The top frame 13 is square, and the two front corners of the bottom surface of the top frame 13 are vertically provided with limiting steel cables 171 connected to the base; so that the tension training steel cable can basically coincide with the position of the limiting steel cable 171, reducing the friction between the load-bearing chassis 16 and the limiting steel cable 171, and increasing the service life of the device.

[0047] The support frame A 11 is arranged at the front end of the base, the middle part of the support frame B 12 is connected to the front end of the support beam 21, and a steering cross frame is arranged at the upper part of the support frame;

[0048] The upper guide wheels 19 are symmetrically arranged on the left and right sides of the top frame 13, the lower guide wheels 19 are arranged on both sides of the base; the middle guide wheels 19 are symmetrically arranged on the left and right ends of the bogie cross frame,

[0049] A folding groove limit baffle 22 is provided on the supporting crossbeam 21, and the two handles 18 on the tension training device are placed in the folding groove of the folding groove limit baffle 22; the two handles 18 are fixed, and the folding groove can prevent the handles 18 from being pulled off due to the self-falling of the load-bearing chassis 16.

[0050] The two ends of the tension training steel cable are respectively fixedly connected to the counterweight tray and the handle 18; a through hole is provided in the middle of the counterweight tray, and two guide steel cables 172 are arranged symmetrically on the left and right, with the upper end thereof being mounted on the top frame 13 and the lower end being mounted on the base.

The rear end of the tension training steel cable passes through the folding line slot and is then fixedly connected to the handle 18. When the hand-pulling steel cable is pulled, each tension training steel cable passes through several guide wheels 19 to convert the hand-pulling force into a vertical upward pulling force, and the load-bearing chassis 16 drives the weight plate 15 to rise vertically along the limit steel cable 171 to achieve the training effect.

[0051] The trunk support pad 23 is provided with straps to fix the trainee on the trunk support pad 23 to prevent the trainee from rolling off during training.

[0052] How to use the device:

[0053] When in use, the swimmer first lies prone on the torso support pad 23, with the head facing the front support frame, the feet backward, and the toes inserted into the rear foot fastener 33.
