DETAILED DESCRIPTION

[0026] 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.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figures 1 to 7As shown, this embodiment provides a sports stretching device, including a base plate 4, a base plate 4, a vertical plate 2 fixedly connected to one side of the base plate 4, a seat cushion mounting plate 3 fixedly connected to the top surface of the vertical plate 2, a seat cushion 1 mounted on the seat cushion mounting plate 3, the vertical plate 2, the seat cushion mounting plate 3, and the base plate 4 form an installation space for a stretching assembly; the stretching assembly includes a leg plate 8, the leg plate 8 is mounted on a slit assembly, the slit assembly is mounted on a leg lifting assembly, the leg lifting assembly is mounted on the base plate 4, the slit assembly is transmission-connected to a slit driving component, and the leg lifting assembly is transmission-connected to a leg lifting driving component.

[0029] The present invention drives the leg-lifting assembly to realize the leg-lifting action through the leg-lifting driving component, drives the two leg panels 8 to expand outward through the splitting driving component to realize the splitting action, and the leg-lifting assembly and the leg-lifting assembly cooperate with each other to realize various stretching exercises. The setting of the seat cushion 1 can make the exerciser more comfortable. Compared with the conventional tensioner, it is more diversified in exercise, and can effectively improve the exercise of the stretching needs of the physical exercisers.

[0030] A further optimized solution is that the leg lifting assembly includes two movable blocks 11 rotatably connected to the base plate 4, the two movable blocks 11 are symmetrically arranged, the rotating shaft outside the movable block 11 is connected to a worm gear 17, the worm gear 17 is meshed with a worm 14, the worm gear 14 is rotatably connected to the side wall of the base plate 4, and the worm gear 14 is transmission connected to the leg lifting drive component.

[0031] A further optimized solution is that the leg-lifting driving component includes a shaking handle 12, which is rotatably connected to the base plate 4, and one end of the shaking handle 12 close to the base plate 4 is axially connected to a second bevel gear 16, the second bevel gear 16 is meshed with a first bevel gear 15, and the first bevel gear 15 is axially connected to the worm 14.

[0032] By shaking the handle 12, the second bevel gear 16 is driven to rotate, the first bevel gear 15 drives the worm 14 to rotate, and the worm 14 further drives the worm wheel 17 to rotate, and the worm wheel 17 drives the movable block 11 to rotate up and down, so that the leg plate 8 rotates up and down. Since the worm wheel 17 and the worm 14 can be self-locking, the leg plate 8 can be prevented from moving downward in this case, which effectively solves the problem of force loss during the stretching process.

[0033] According to a further optimized solution, the slit assembly includes a rotating gear 7 rotatably connected to the top surface of the movable block 11, the leg plate 8 is installed on one side of the rotating gear 7, and the rotating gear 7 is transmission-connected to the slit driving component.

[0034] A further optimized solution is that the fork driving component includes a sliding block 6 slidably connected to the top surface of the base plate 4, a give way groove 601 is opened inside the sliding block 6, a pull rod 5 is connected to the end of the sliding block 6 away from the vertical plate 2, both sides of the sliding block 6 are meshed with two rotating gears 7, the pull rod 5 is slidably matched with the base plate 4, and a spring 13 is installed between the sliding block 6 and the vertical plate 2.

[0035] By moving the pull rod 5, the pull rod 5 drives the sliding block 6 to move, so that the sliding block 6 drives the rotating gear 7 to rotate, and the rotating gear 7 can further drive the leg plate 8 to expand outward to achieve the fork tensioning. The function of the spring 13 is to make the sliding block 6 and then the leg plate 8 return to its original position.

[0036] According to a further optimized solution, the pull rod 5 is threadedly connected to the sliding block 6 .

[0037] The pull rod 5 and the sliding block 6 are threadedly connected to each other so that people of different heights can exercise with each other. When the human body is higher, the arm length is also higher. The pull rod 5 can be rotated appropriately to increase the distance between the end of the pull rod 5 and the sliding block 6.

[0038] A further optimized solution is that the end of the pull rod 5 away from the sliding block 6 is fixedly connected to the push-pull handle 10, the middle part of the push-pull handle 10 is rotatably connected to the annular sleeve 1001, the outer side of the annular sleeve 1001 is fixedly connected to the limiting block 1002, a torsion spring is installed between the annular sleeve 1001 and the push-pull handle 10, the side of the bottom plate 4 away from the sliding block 6 is fixedly connected to the limiting strip 9, a plurality of limiting grooves 901 are opened on the limiting strip 9 along the length direction, and the limiting block 1002 matches the limiting groove 901.

[0039] The cooperation between the limiting groove 901 on the limiting strip 9 and the limiting block 1002 can make the limiting block 1002 gradually stuck in the corresponding limiting groove 901. At the same time, the limiting block 1002 also has a limiting function to prevent the pull rod 5 from retreating under the action of the spring 13, thereby achieving a fixed support for the split tie rod.

[0040] In a further optimized solution, a plurality of baffles 18 are installed on the side where the two leg plates 8 are close to each other, and the plurality of baffles 18 are arranged at equal intervals along the length direction of the leg plates 8. The function of the baffles 18 is to provide an outward thrust during the splitting process.
