DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figures 1 to 7As shown, in an embodiment of the present invention, a multifunctional auxiliary device for sports training includes a base 1, a positioning seat 2 is installed on the top of the base 1, support rollers 3 are fixedly connected to both ends of the positioning seat 2, and a limiting shaft 9 is fixedly installed on the bottom end of the positioning seat 2, and the limiting shaft 9 is embedded in the interior of the base 1;

[0036] The bottom end of the positioning seat 2 is fixedly connected with a first pull rope 4, one end of the first pull rope 4 away from the positioning seat 2 is fixedly installed with a first mounting plate 22, a first connecting hook 5 is fixedly installed on the side wall of the first mounting plate 22, and a stretching component is arranged on one side of the first mounting plate 22;

[0037] The stretching assembly includes a first spring 7 arranged on one side of the first mounting plate 22, and a plurality of first springs 7 are evenly distributed. Both ends of the first spring 7 are fixedly connected to the second mounting plates 23, one of the second mounting plates 23 is fixedly installed on the inner wall of the base 1, and the side wall of the other second mounting plate 23 is fixedly installed with a second connecting hook 6, and the second connecting hook 6 is embedded in the inside of the first connecting hook 5, and a protective assembly is arranged above the first connecting hook 5 and the second connecting hook 6.

[0038] Through the arrangement of the positioning seat 2, the support roller 3 and the limiting shaft 9, during physical training, the trainee can sit on the top of the base 1 facing the positioning seat 2, place the feet on the bottom of the support roller 3, and perform sit-up training;

[0039] Through the setting of the stretching component, the trainee sits on the top of the base 1 facing the positioning seat 2, places the feet on the bottom of the support roller 3, straightens the back, supports the hands behind the back or on both sides of the body to maintain balance, slowly lifts the legs to separate the positioning seat 2 from the base 1, and makes the legs form an angle of about 45 degrees with the base 1, and lifts the legs reciprocatingly to perform leg strength training;

[0040] During the reciprocating leg-lifting training, the first pull rope 4 is connected to the first spring 7. Under the elastic force of the first spring 7, a certain weight is applied to the leg strength training, so that the leg muscles, including the quadriceps femoris, calf muscles and buttocks muscles on the front of the thigh, can be trained more comprehensively. This comprehensive training helps to improve the strength and endurance of the legs.

[0041] At the same time, multiple first springs 7 are provided, and each first spring 7 is set to a different weight or resistance strength. By adjusting different spring combinations, the resistance to lifting the positioning seat 2 can be adjusted according to the individual's physical condition, thereby meeting the training needs of athletes of different levels.

[0042] like Figure 2 and Figure 3 As shown, a second limiting plate 13 is disposed on one side of the second mounting plate 23 , and the second limiting plate 13 is fixedly mounted inside the base 1 .

[0043] The position of the second mounting plate 23 is limited by the second limiting plate 13. When the positioning seat 2 is lifted for leg strength training, the first pull rope 4 drives the first spring 7 to stretch. When the positioning seat 2 is lowered, the second mounting plate 23 moves to one side of the second limiting plate 13 when it is reset by the elastic force of the first spring 7.

[0044] like Figure 1 and Figure 2 As shown, the protection assembly includes a protection plate 14 arranged above the first connecting hook 5 and the second connecting hook 6 , and two protection plates 14 are symmetrically arranged, and both protection plates 14 are slidably installed on the top of the base 1 .

[0045] Protecting the connection position between the first connecting hook 5 and the second connecting hook 6 can not only prevent external debris from entering, but also make the surface of the base 1 a whole plane, making it convenient for trainers to train at the top of the base 1.

[0046] like Figure 6 and Figure 7 As shown, the side walls of the two protection plates 14 are fixedly connected with rack plates 15 , a gear 16 is meshedly connected between the two rack plates 15 , and a rotating shaft 17 is fixedly installed inside the gear 16 .

[0047] When one of the guard plates 14 moves, the movement of the guard plate 14 drives the rotation of the gear 16, and the rotation of the gear 16 drives the movement of the other rack plate 15, so that the two guard plates 14 move synchronously, so that the two guard plates 14 can be opened and closed synchronously.

[0048] like Figure 6 and Figure 7 As shown, the rotating shaft 17 is rotatably installed inside the base 1, and a coil spring 18 is installed on the outer wall of the rotating shaft 17. One side of the two protective plates 14 is slidably connected to a limit rod 20. The two limit rods 20 are fixedly connected by a connecting rod 19, and the connecting rod 19 is embedded in the inside of the base 1.

[0049] When the two protection plates 14 are closed, the coil spring 18 stores elastic potential energy and limits the protection plates 14 through the two limiting rods 20;

[0050] When the first spring 7 with different elastic force needs to be replaced, the limiting rod 20 is slid to the side away from the protective plate 14. When the limiting rod 20 is separated from the protective plate 14, the elastic potential energy released by the coil spring 18 drives the rotating shaft 17 to rotate, so that the two protective plates 14 move outward and open;

[0051] After replacement, the protective plate 14 is pushed inwards, so that the coil spring 18 stores elastic potential energy, and the protective plate 14 is limited by the limiting rod 20 .

[0052] like Figure 6 As shown, a second spring 21 is arranged on one side of the connecting rod 19, and the second springs 21 are evenly arranged.

[0053] like Figures 1 to 7 As shown, a ring sleeve 10 is provided on one side of each of the two support rollers 3, and a second pull rope 11 is fixedly connected to one side of the ring sleeve 10. The end of the second pull rope 11 away from the ring sleeve 10 passes through the interior of the support roller 3 and the positioning seat 2 and extends to the interior of the base 1. The bottom end of the second pull rope 11 is fixedly mounted on the side wall of the first mounting plate 22.

[0054] The trainee kneels on the top of the base 1 facing the positioning seat 2 in a four-legged position, with both hands placed just below the shoulders, knees perpendicular to the hips, and the back parallel to the ground to ensure the stability of the body. Then one of the hands is put inside the ring 10 and lifted upward to fully exercise the arm and forearm muscles.

[0055] like Figure 1 , Figure 2 and Figure 4 As shown, a first limiting plate 12 is fixedly mounted on the outer wall of the second pull rope 11 , and the first limiting plate 12 is arranged on one side of the supporting roller 3 .

[0056] The ring sleeve 10 is limited.

[0057] like Figure 2 and Figure 4 As shown, the outer walls of the first pull rope 4 and the second pull rope 11 are both provided with pulleys 8 , and the pulleys 8 are rotatably installed inside the base 1 .

[0058] Reducing friction during stretching makes stretching smoother and thus more efficient.

[0059] A method of a multifunctional auxiliary device for sports training, comprising the following steps:

[0060] S1: When doing sit-up training, the trainee can sit on the top of the base 1 facing the positioning seat 2, with the feet placed on the bottom of the support roller 3, and do sit-up training;

[0061] S2: When doing leg training, the trainee sits on the top of the base 1 facing the positioning seat 2, places the feet on the bottom of the support roller 3, straightens the back, supports the hands behind the back or on both sides of the body to maintain balance, slowly lifts the legs to separate the positioning seat 2 from the base 1, and makes the legs and the base 1 form an angle of about 5 degrees with the first connecting hook of the first pull rope 4, and lifts the legs reciprocatingly to perform leg strength training;

[0062] S3: When performing hand training, the trainee kneels on the top of the base 1 facing the positioning seat 2 in a four-legged position, places both hands just below the shoulders, knees perpendicular to the hips, keeps the back parallel to the ground, ensures the stability of the body, and then puts one hand inside the ring 10 and lifts it upwards, so that the arm and forearm muscles are fully exercised;

[0063] S4: When it is necessary to replace the first spring 7 with a different elastic force, slide the limit rod 20 to the side away from the protective plate 14. When the limit rod 20 is separated from the protective plate 14, the elastic potential energy is released by the coil spring 18 to drive the rotating shaft 17 to rotate. The rotation of the rotating shaft 17 drives the rotation of the gear 16. The rotation of the gear 16 drives the movement of the rack plate 15. The movement of the rack plate 15 drives the movement of the protective plate 14, so that the two protective plates 14 move outward and open. Then, take the first connecting hook 5 out of the second connecting hook 6, hang it in the other second connecting hook 6, and replace the first spring 7 with different elastic force.

[0064] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
