[0032] The present utility model will be further described below in conjunction with the accompanying drawings and specific implementation manners.

[0033] Embodiment 1

[0034] As Figures 1-9 shown, this embodiment provides an inverted exerciser 1, which includes a lumbar arch frame 10, a backrest 20, and a headrest 30. The backrest 20 is pivotally connected to the lumbar arch frame 10, and the backrest 20 and the lumbar arch frame 10 are pivotally connected by the mutual sleeving of a pivot sleeve and a rotating shaft rod. Specifically, in this embodiment, the lumbar arch frame 10 includes two support leg frames 11 and a rotating shaft rod 13 connected between the two support leg frames 11. The middle part of the backrest 20 is pivotally connected to the rotating shaft rod 13. The rotating shaft rod 13 is arranged in the middle of the tops of the two support leg frames 11, so that the backrest 20 is pivotally connected to the middle position at the top of the lumbar arch frame 10. The inverted exerciser 1 is used for users to practice inverted exercises.

[0035] The backrest 20 includes a main structural tube 21 and rollers 25 rotatably connected to both sides of the main structural tube 21. 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 rotating shaft rod 13, so that the backrest 20 is pivotally connected to the rotating shaft rod 13. Multiple massage protrusions can be arranged on the surface of the roller 25, and the massage protrusions can massage the muscles, thereby enhancing the exercise effect of the inverted 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 play a role in providing a complete surface support. It is easy to understand that in other embodiments, a rotating shaft rod can also be arranged on the backrest 20, and a pivot sleeve can be arranged on the lumbar arch frame 10, so as to pivotally connect the backrest 20 to the lumbar arch frame 10.

[0036] An angle locking mechanism is provided between the arch waist support 10 and the backrest 20. In this embodiment, the angle locking mechanism is arranged between the pivot sleeve 23 and the rotating shaft rod 13. Specifically, a first mounting member 17 is fixedly connected to the rotating shaft rod 13, and a first locking structure is arranged 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 arranged on the second mounting member 24, wherein 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 arch waist support 10 and the backrest 20 can be locked. Thus, the user can better find a suitable angle through the back for exercise, so that the user can exert force better, and the safety during use can also be improved.

[0037] In this embodiment, the first locking structure is a protruding pin 16 arranged on the first mounting member 17 as the pin, and the second locking structure is an opening 242 arranged on the second mounting member 24 as the bayonet. As Figures 3-5 shown, the protruding pin 16 is displaceably connected to the first mounting member 17, so that the protruding pin 16 can be engaged with or disengaged from the opening 242 by displacement. When the protruding 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 arch waist support 10 can be locked. Using the engagement of the protruding pin 16 and the opening 242 as the angle locking mechanism has a simple and reliable structure, is easy to manufacture, has a low cost, and improves the safety of the device.

[0038] As Figures 2-5 shown, in this embodiment, the number of the openings 242 on the second mounting member 24 is 3, so that the backrest 20 can be locked relative to the arch waist support 10 at three different angles, as Figure 9 shown. Of course, the number of the openings 242 on the second mounting member 24 can also be more or less than 3, so that the backrest 20 can be locked relative to the arch waist support 10 at more or fewer different angles. For example, the number of the openings 242 on the second mounting member 24 can also be 2 or 4 or 5.

[0039] The rotating shaft rod 13 can be composed of a middle tube 131 and connecting sleeves 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 screws 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 leg 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 into a plate shape. 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 into 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 Figures 4-5 shown, the outer edge of the first mounting member 17 also extends along the axial direction of the connecting sleeve 132 and towards the direction close to the second mounting member 24 to form a flange 171. The flange 171 forms a protection structure towards the second mounting member 24, which can prevent the angle locking mechanism from being accidentally touched, thereby improving safety.

[0040] In other embodiments, the angle locking mechanism between the lumbar arch 10 and the backrest 20 can also be of other types. For example, the pivot sleeve and the rotating shaft rod can be locked to each other by a locking pin to form an angle locking mechanism; or a buckle can be used to lock the pivot sleeve and the rotating shaft rod to each other to form an angle locking mechanism.

[0041] An angle limiting mechanism is also provided between the lumbar arch 10 and the backrest 20. In this embodiment, the angle limiting mechanism is provided between the pivot sleeve 23 and the rotating shaft rod 13. Specifically, a first limiting structure is further provided on the first mounting member 17; a second limiting structure is further provided on the second mounting member 24, where the first limiting structure and the second limiting structure are a set of convex blocks and sliding grooves that can be mutually limited and matched, so that the maximum rotation angle of the pivot sleeve 23 relative to the rotating shaft rod 13 can be limited. In this embodiment, the first limiting structure is a convex platform 15 provided on the first mounting member 17 as a convex block, and the second limiting structure is an arc-shaped groove 241 provided on the second mounting member 24 as a sliding groove. As Figures 3-5 shown, the arc-shaped groove 241 is at least partially arranged around the pivot sleeve 23, and the convex platform 15 can slide in the arc-shaped groove 241 and is limited by the arc-shaped groove 241, so that the maximum value of the adjustable angle of the backrest 20 relative to the lumbar arch 10 is limited, and the safety of the inverted exerciser 1 is greatly improved. And the angle locking mechanism and the angle limiting mechanism are both arranged between the first mounting member 17 and the second mounting member 24, with a compact structure, simplified number of parts, and low manufacturing cost.

[0042] In other embodiments, the angle limiting mechanism between the lumbar support 10 and the backrest 20 can also be of other types. For example, an angle limiting mechanism can be formed by setting a limit switch; or an angle limiting mechanism can be formed by setting a limit stop.

[0043] As Figures 2-5 shown, in this embodiment, a second mounting member 24 is provided at each end of the pivot sleeve 23, corresponding to the first mounting members 17 on the two connecting sleeves 132 respectively, so that the force on the inverted exerciser 1 is more balanced.

[0044] As Figures 1-2 shown, the support leg frame 11 is of an inverted U-shaped structure. Anti-slip foot pads 111 are sleeved on the legs of the support leg frame 11 that contact the ground. The anti-slip foot pads 111 are made of rubber, for example, to play an anti-slip role when the inverted exerciser 1 is placed on the ground.

[0045] An armrest 12 is provided on the outer side of the support leg frame 11, so that it is convenient for the user to grasp the armrest 12 to exercise. The force application point is better during exercise, the exercise is more convenient and the safety is higher.

[0046] As a further improvement of this embodiment, as Figure 8 shown, a buffer elastic rope 40 is connected between the two support leg frames 11 of the lumbar support 10 and the main structural tube 21 of the backrest 20. The buffer elastic rope 40 can play a buffering role in the rotational movement of the backrest 20 on the lumbar support 10, preventing the backrest 20 from rotating too fast during exercise and causing potential safety hazards. Moreover, the buffer elastic rope 40 can help the backrest 20 return to the initial position in time, making it more convenient to use.

[0047] As Figure 8 shown, in the initial state, the total of three connection points of the buffer elastic rope 40 on the two support leg frames 11 of the lumbar support 10 and the main structural tube 21 of the backrest 20 form a "one" character arrangement. Such a setting is beneficial to the installation of the buffer elastic rope, the installation is simple and efficient, and it is conducive to self-maintenance after aging; in the state where the buffer elastic rope 40 is stretched and stressed, the total of three connection points of the buffer elastic rope 40 on the two support leg frames 11 of the lumbar support 10 and the main structural tube 21 of the backrest 20 form a "V" character arrangement. The buffer elastic rope 40 is in a stretched state. According to Hooke's law, the longer the buffer elastic rope 40 is stretched, the greater the tension on the rope, so that the buffer protection force increases, and the structure is simple and efficient.

[0048] As Figure 7As 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 one 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.

[0049] The headrest tube 31 is provided with a plurality of positioning holes 311 along the length direction, the main structure tube 21 is threadedly connected with the locking piece 20, and the locking piece 20 can extend into the inner cavity of the main structure tube 21, so that when the headrest 30 is adjusted to a suitable height relative to the backrest 20, the locking piece 20 rotates and one end of the locking piece 20 extends into the inner cavity of the main structure tube 21, and one end of the locking piece 20 cooperates with the positioning hole 311 to lock the headrest tube 31, thereby locking the height of the headrest 30 relative to the backrest 20. The height adjustment structure is simple and reliable, and can improve the safety performance of the inverted exerciser 1.

[0050] The headrest 30 is detachably connected to the backrest 20. In some embodiments, the inverted exerciser 1 may not be provided with 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 and is 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 is swung and flipped to the front or back side of the arch frame 10, it tilts, and one end of it touches the ground and the other end is tilted above the arch frame 10; when the arch frame 10 is grasped with both hands and the backrest 20 is flipped to the shoulders touching the ground and the waist and hips are off the ground and the feet are straightened, the human body is inverted.

[0051] Example 2

[0052] This embodiment is a simplified embodiment of embodiment 1. Figure 10 As shown, in this embodiment, the first mounting member 17' and the second mounting member 24' are not provided with an angle locking mechanism, and the rest is the same as that of embodiment 1. This embodiment has a simpler structure and is more convenient to process.
