DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Example: Reference Figure 1-5 The leg stretching exerciser shown in the figure comprises a base 1, a fixing plate 2 is fixed on the top of the base 1, two first springs 3 are fixed on the left side of the fixing plate 2, a carrier plate 4 is fixed on the left end of the two first springs 3, a seat plate 5 is fixed on the top of the carrier plate 4, a backing plate 26 is fixed on the upper surface of the seat plate 5, two armrests 27 are fixed on the backing plate 26, and the coordinated use of the backing plate 26 and the armrests 27 can provide back and arm support for elderly users, making the elderly users safer when exercising, a supporting plate 6 is fixed on the left side of the carrier plate 4, a first stud 7 is threadedly connected to the supporting plate 6, a first card slot 8 adapted to the first stud 7 is opened on the base 1, a slide plate 9 is fixed on the right side of the carrier plate 4, and a first stud 7 is threadedly connected to the first stud 7. A first slide groove 10 is provided on the fixed plate 2, and the slide plate 9 passes through the inside of the first slide groove 10. A reserved groove 11 is provided on the front and rear sides of the fixed plate 2. A carrier tube 12 is rotatably connected between the upper and lower inner walls of the reserved groove 11 through a pin shaft. A carrier tube 13 is fixed to the outer wall of the carrier tube 12. A second stud 14 is threadedly connected to the fixed plate 2. A second card groove matched with the second stud 14 is provided on the carrier tube 13. Knobs are fixed to the tops of the first stud 7 and the second stud 14. A second spring 15 is fixed inside the carrier tube 13. A telescopic rod 16 is fixed to the right end of the second spring 15. The telescopic rod 16 is slidably matched with the inner wall of the carrier tube 13, and a pedal 18 is fixed to the right end of the telescopic rod 16.

[0025] With the help of the first stud 7, it is possible to control whether the seat plate 5 can move on the base 1, and with the help of the second stud 14, the use direction of the carrier tube 13 can be controlled, so that the elderly user can use the first spring 3 and the second spring 15 to flex and extend the legs to achieve lateral stretching movement of the legs, and can also use the two carrier tubes 13 to swing outward to achieve further stretching during the opening and closing swing of the legs.

[0026] Among them, a universal caster 17 is provided at the bottom of the carrier tube 13, and the universal caster 17 makes the carrier tube 13 smoother when opening and closing and swinging. A fixed caster 20 is provided at the bottom of the carrier plate 4, and a second slide groove 21 for sliding the fixed caster 20 is provided on the base 1. With the help of the fixed caster 20, the seat plate 5 can be supported to slide better in the second slide groove 21 provided on the base 1, so that the seat plate 5 can move more smoothly.

[0027] Among them, two limit columns 22 are fixed through the slide plate 9, and the two limit columns 22 are respectively arranged on the left and right sides of the fixed plate 2. The two limit columns 22 can limit the range of movement of the slide plate 9 inside the first slide groove 10 to prevent the first spring 3 from being over-stretched or compressed.

[0028] Among them, a plurality of auxiliary rollers 23 are rotatably connected between the front and rear inner walls of the first slide groove 10 through bearings. The plurality of auxiliary rollers 23 are respectively located on the upper and lower sides of the slide plate 9, and the slide plate 9 is tightly fitted with the auxiliary rollers 23. The plurality of auxiliary rollers 23 respectively arranged on the upper and lower sides of the slide plate 9 make the slide plate 9 slide more smoothly in the first slide groove 10.

[0029] Among them, a limit rod 24 is fixed through the telescopic rod 16, and a limit groove for the limit rod 24 to slide is opened on the carrier tube 13. The cooperation between the limit rod 24 and the limit groove can prevent the telescopic rod 16 from being completely separated from the carrier tube 13, and can prevent the second spring 15 from being over-stretched or compressed.

[0030] Among them, a limiting belt 19 is fixed to the left side of the pedal 18, and a strap 25 is fixed on the telescopic rod 16. The strap 25 is provided with Velcro. The ankles of the elderly user can be bound to the telescopic rod 16 by using the strap 25 and the Velcro thereon. The elderly user's feet are placed on the pedal 18, and the limiting belt 19 can limit their feet. In this way, the stability of the elderly user's legs during exercise can be guaranteed to prevent them from suddenly falling off the pedal 18 and getting injured.

[0031] Working principle of this utility model:

[0032] When in use, the base 1 is placed on a horizontal ground and fixed, the elderly user sits on the seat plate 5 with his buttocks, the back can lean on the back plate 26, the arms can be placed on the armrests 27, the elderly user steps on the pedal 18, the limiting belt 19 can limit the user's foot, the strap 25 is passed around the user's ankle, and the user's leg is bound to the telescopic rod 16 with Velcro, at this time, the user's leg is in an arched state, the first stud 7 is disengaged from the first slot 8, and the second stud 14 is inserted into the second slot, so that the carrier 13 cannot rotate, the elderly user can exert force to increase the distance between the seat plate 5 and the pedal 18 until the legs are straightened and the body is slightly arched forward, at this time the first spring 3 and the second spring 15 are both in a stretched state, after a few seconds, the body relaxes, the seat plate 5 and the pedal 18 are brought close, the legs are arched again, and the user's leg tendons are stretched and the knee and ankle joints are active;

[0033] In order to further stretch the leg tendon, the first stud 7 can be rotated and inserted into the first slot 8, forcing the seat plate 5 to be unable to move, and the second stud 14 can be disengaged from the second slot. At this time, the carrier tube 13 can rotate around the carrier tube 12, and the elderly user can swing the two carrier tubes 13 outward to achieve further stretching during the opening and closing swing of the legs. In this way, the leg stretching exercise needs of elderly users can be met.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
