[0030] To further illustrate various embodiments, the present invention is provided with accompanying drawings. These drawings form part of the disclosure of this invention and are primarily used to illustrate the embodiments and, in conjunction with the relevant description in the specification, to explain the operating principles of the embodiments. By referring to these drawings, those skilled in the art will understand other possible implementations and the advantages of this invention. The components in the figures are not drawn to scale, and similar reference numerals are generally used to represent similar components.

[0031] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0032] like Figure 1-9 As shown, this embodiment provides a handstand exerciser 1, comprising a waist frame 10, a backrest 20, and a headrest 30. The backrest 20 is pivotally connected to the waist frame 10. The waist frame 10 includes two support legs 11 and a central shaft 13 connected between the two support legs 11. The middle portion of the backrest 20 is pivotally connected to the central shaft 13. The central shaft 13 is positioned in the middle of the tops of the two support legs 11, so that the backrest 20 is pivotally connected to the middle position of the top of the waist frame 10. The handstand exerciser 1 is used for users to practice handstand exercises.

[0033] The backrest 20 includes a main structural tube 21 and rollers 25 rotatably connected to both sides of the main structural tube 21, so that the backrest 20 has a structure in the shape of the Chinese character "丰". A connecting tube 22 is connected to the back side of the main structural tube 21. One end of the connecting tube 22 is connected to the main structural tube 21, and the other end is connected to a pivot sleeve 23. The pivot sleeve 23 is sleeved on the outer periphery of the central shaft 13, so that the backrest 20 is pivotally connected to the central shaft 13. Multiple massage protrusions can be provided on the surface of the roller 25, and the massage protrusions can massage the muscles, thereby enhancing the exercise effect of the inversion exerciser 1. Of course, in other embodiments, the backrest 20 can also adopt a plate - type backrest, which is used for users with back and spinal injuries. The backrest of this structure can provide a complete surface support.

[0034] An angle - locking mechanism is provided between the lumbar arch support 10 and the backrest 20. In this embodiment, the angle - locking mechanism is provided between the pivot sleeve 23 and the central shaft 13. Specifically, a first mounting member 17 is fixedly connected to the central shaft 13, and a first locking structure is provided on the first mounting member 17; a second mounting member 24 is fixedly connected to the pivot sleeve 23. The first mounting member 17 and the second mounting member 24 are opposite and arranged side by side, and a second locking structure is provided on the second mounting member 24. The first locking structure and the second locking structure are a set of a pin and a bayonet that can be engaged with each other, so that the angle between the lumbar arch support 10 and the backrest 20 can be locked. Thus, the user can better find a suitable angle through the back to roll the roller, so that better force can be exerted, and the safety during use can also be improved.

[0035] In this embodiment, the first locking structure is a convex pin 16 provided on the first mounting member 17 as the pin, and the second locking structure is an opening 242 provided on the second mounting member 24 as the bayonet. As Figure 3-5 shown, the convex pin 16 is displaceably connected to the first mounting member 17, so that the convex pin 16 can be engaged with or disengaged from the opening 242 by displacement. When the convex pin 16 is engaged with the opening 242, the angle of the first mounting member 17 relative to the second mounting member 24 is locked, so that the angle of the backrest 20 relative to the lumbar arch support 10 can be locked. Using the way of engaging the convex pin 16 with the opening 242 as the angle - locking mechanism, the structure is simple and reliable, easy to manufacture, with low cost, and the safety of the device is improved.

[0036] As Figure 2-5 shown, in this embodiment, the number of openings 242 on the second mounting member 24 is 3, so that the backrest 20 can be locked at three different angles relative to the lumbar arch support 10. As Figure 9Of course, the number of openings 242 on the second mounting member 24 can be more or less than three, so that the backrest 20 can be locked at more or fewer different angles relative to the waist frame 10. For example, the number of openings 242 on the second mounting member 24 can be two, four, or five.

[0037] The central axis 13 can be composed of a middle tube 131 and a connecting sleeve 132 connected to both ends of the middle tube 131. The middle tube 131 is sleeved in the inner cavity of the connecting sleeve 132, and the middle tube 131 and the connecting sleeve 132 are locked to each other by a screw 17. One end of the connecting sleeve 132 is locked and connected to the middle tube 131, and the other end of the connecting sleeve 132 is fixedly connected to the support bracket 11. In this embodiment, the first mounting member 17 is connected to the outer periphery of the connecting sleeve 132, and extends radially outward from the outer periphery of the connecting sleeve 132 to form a plate shape along the radial direction of the connecting sleeve 132. The second mounting member 24 is connected to the outer periphery of the pivot sleeve 23, and extends radially outward from the outer periphery of the pivot sleeve 23 to form a plate shape. The plate-shaped first mounting member 17 and the second mounting member 24 have a simpler structure and are easier to manufacture. Preferably, as Figure 4-5 As shown, the outer edge of the first mounting member 17 also extends along the axial direction of the connecting sleeve 132 and toward the second mounting member 24 to form a flange 171. The flange 171 forms a protective structure toward the second mounting member 24, which can prevent the angle locking mechanism from being accidentally touched, thereby improving safety.

[0038] An angle limiting mechanism is also provided between the waist frame 10 and the backrest 20. In this embodiment, the angle limiting mechanism is provided between the pivot sleeve 23 and the central axis 13. Specifically, a first limiting structure is also provided on the first mounting member 17; a second limiting structure is also provided on the second mounting member 24, wherein the first limiting structure and the second limiting structure are a group of protrusions and slide grooves that can cooperate with each other to limit each other, so that the maximum rotation angle of the pivot sleeve 23 relative to the central axis 13 can be limited. In this embodiment, the first limiting structure is the boss 15 provided on the first mounting member 17 as a protrusion, and the second limiting structure is the arc groove 241 provided on the second mounting member 24 as a slide groove. As shown Figure 3-5 As shown, the arcuate groove 241 is at least partially disposed around the pivot sleeve 23. The boss 15 is able to slide within the arcuate groove 241 and is restrained by the arcuate groove 241, thereby limiting the maximum adjustable angle of the backrest 20 relative to the arch frame 10, greatly enhancing the safety of the inverted exerciser 1. Furthermore, the angle locking mechanism and the angle limiting mechanism are simultaneously disposed between the first mounting member 17 and the second mounting member 24, resulting in a compact structure, a simplified number of parts, and low manufacturing costs.

[0039] like Figure 2-5As shown, in this embodiment, a second mounting member 24 is provided at each end of the pivot sleeve 23, respectively corresponding to the first mounting members 17 on the two connecting sleeves 132, so that the force on the inverted exerciser 1 is more balanced.

[0040] like Figure 1-2 As shown, the support frame 11 is an inverted U-shaped structure. The support legs of the support frame 11 that contact the ground are provided with anti-skid pads 111, which are made of rubber, for example, to prevent the handstand exerciser 1 from slipping when placed on the ground.

[0041] An armrest 12 is provided on the outer side of the supporting leg frame 11, so that the user can conveniently grasp the armrest 12 to exercise, and the fulcrum is better during exercise, making exercise more convenient and safer.

[0042] As a further improvement of this embodiment, Figure 8 As shown, a buffer elastic cord 40 is connected between the two support legs 11 of the arch waist frame 10 and the main structural tube 21 of the backrest 20. The buffer elastic cord 40 can cushion the rotational movement of the backrest 20 on the arch waist frame 10, preventing the backrest 20 from rotating too quickly during exercise and causing safety hazards. The buffer elastic cord 40 also helps the backrest 20 return to its original position in a timely manner, making it more convenient to use.

[0043] like Figure 7 As shown, the headrest 30 is detachably and height-adjustably connected to the backrest 20. Specifically, the headrest 30 includes a headrest tube 31 and a headrest roller 32 connected to one end of the headrest tube 31. The headrest tube 31 is telescopically inserted into the inner cavity of the main structure tube 21 of the backrest 20, and the end of the main structure tube 21 connected to the headrest tube 31 is connected to a locking member 20, which can lock the relative position of the main structure tube 21 and the headrest tube 31. Since the headrest 30 is height-adjustably connected to the backrest 20, it can support the heads of practitioners of different heights, has a wider range of applications, and is more comfortable for users to use.

[0044] The headrest tube 31 is provided with a plurality of positioning holes 311 along its length. The main structure tube 21 is threadedly connected to the locking member 20, and the locking member 20 can extend into the inner cavity of the main structure tube 21. Therefore, when the headrest 30 is adjusted to a suitable height relative to the backrest 20, the locking member 20 rotates and one end of the locking member 20 extends into the inner cavity of the main structure tube 21. One end of the locking member 20 engages with the positioning holes 311, thereby locking the headrest tube 31 and locking the headrest 30 relative to the backrest 20. This height adjustment structure is simple and reliable, and can improve the safety performance of the inverted exerciser 1.

[0045] The headrest 30 is detachably connected to the backrest 20. The headrest 30 is detachably connected to the backrest 20, so that at the beginning of training, the headrest can be inserted to protect the head and neck of the practitioner; and at the later stage of training, the headrest can be removed for advanced training, such as Figure 10 In this embodiment, the headrest tube 31 is detachably inserted into the inner cavity of the main structural tube 21 of the backrest 20, thereby allowing the headrest 30 to be detachably connected to the backrest 20. In other embodiments, the headrest 30 can be detachably connected to the backrest 20 in other ways. For example, the headrest 30 can be pivotally connected to the backrest 20, so that when in use, the headrest 30 pivots relative to the backrest 20 to a working position, thereby forming a detachable connection between the headrest 30 and the backrest 20.

[0046] In some embodiments, the inversion exerciser 1 can also be provided without the headrest 30, which is also a feasible technical solution. In this solution, the arch frame 10 is placed on the ground to serve as an armrest, and the backrest 20 is provided for the waist and back to lie on in a seesaw-like manner. The middle of the back of the backrest 20 is eccentrically hinged to the middle of the top of the arch frame 10. When the backrest 20 swings and flips to the front or back of the arch frame 10, it tilts, with one end touching the ground and the other end tilting above the arch frame 10. When the person lies on the arch frame 10 with both hands, the backrest 20 flips to the ground with the shoulders touching the ground, the waist and hips off the ground, and the feet are straight, the person is inverted.

[0047] In this embodiment, the headrest 30 is detachably connected to the backrest 20, so that at the beginning of training, the headrest can be inserted to protect the head and neck of the practitioner; and in the later stage of training, the headrest can be removed for advanced training, and the practitioner can perform training movements of higher difficulty, so that the practitioner has more training methods to choose from, and the training effect is further improved.

[0048] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the form and details of the present invention without departing from the spirit and scope of the present invention as defined by the appended claims, and all of these changes are within the scope of protection of the present invention.
