[0031] The present invention is further described in detail below with reference to the embodiments given in the accompanying drawings.

[0032] like Figures 1 to 9 As shown, a fitness device described in this embodiment includes a base 1, a left support plate 2, a right support plate 3, a left limit locking mechanism 4 and a right limit locking mechanism 5, wherein the left support plate 2 is connected to the left side of the base 1 and can be rotated relative to the base 1 to adjust the angle between itself and the right support plate 3, the right support plate 3 is connected to the right side of the base 1 and can be rotated relative to the base 1 to adjust the angle between itself and the left support plate 2, a left handle 6 is provided on the left support plate 2, and a right handle 7 is provided on the right support plate 3, the left limit locking mechanism 4 is used to lock the left support plate 2 on the base 1 when it is rotated to a desired position, and the right limit locking mechanism 5 is used to lock the right support plate 3 on the base 1 when it is rotated to a desired position.

[0033] As described above, the left and right sides of the base 1 are respectively provided with a first slide groove 11 and a second slide groove 12, and the ends of the left support plate 2 and the right support plate 3 close to the base 1 are respectively provided with a first sliding portion 21 and a second sliding portion 31, the first sliding portion 21 is slidably matched with the first slide groove 11 so that the left support plate 2 can rotate relative to the base 1, and the second sliding portion 31 is slidably matched with the second slide groove 12 so that the right support plate 3 can rotate relative to the base 1.

[0034] As described above, a plurality of first limiting holes 110 are arranged at intervals along the sliding track of the first sliding connection portion 21 in the first sliding groove 11. The left limiting locking mechanism 4 includes a left locking pin 41 and a left return spring 42. The left locking pin 41 is movably arranged at the end of the left support plate 2 close to the base 1. The left return spring 42 is used to keep the left locking pin 41 moving toward the base 1. The front end of the left locking pin 41 can be inserted into any one of the first limiting holes 110 to lock the left support plate 2 in the corresponding position of the base 1. The tail of the left locking pin 41 is provided with a left unlocking push button 410. Pushing the left unlocking push button 410 in the direction away from the base 1 can cause the left locking pin 41 to escape from the first limiting hole 110 and release the lock on the left support plate 2. A plurality of second limiting holes 120 are arranged at intervals along the sliding track of the second sliding connection portion 31 in the second sliding groove 12. The right limiting locking mechanism 5 includes a right locking pin 51 and a right return spring 52. The right locking pin 51 is movably arranged at one end of the right supporting plate 3 close to the base 1. The right return spring 52 is used to keep the right locking pin 51 moving toward the base 1. The front end of the right locking pin 51 can be inserted into any second limiting hole 120 to lock the right supporting plate 3 at the corresponding position of the base 1. A right unlocking push button 510 is provided at the tail of the right locking pin 51. By pushing the right unlocking push button 510 in the direction away from the base 1, the right locking pin 51 can be disengaged from the second limiting hole 120 and the lock on the right supporting plate 3 can be released.

[0035] When the distance between the left and right handles 6 and 7 needs to be adjusted, it is only necessary to rotate the left and right support plates 2 and 3 to adjust the angle between them. The rotation process of the left support plate 2 is as follows: push the left unlocking push button 410 away from the base 1 to make the left locking pin 41 escape from the current first limiting hole 110, then rotate the left support plate 2 to the desired position along the first slide 11, then release the left unlocking push button 410, so that the left locking pin 41 is inserted into the first limiting hole 110 at another corresponding position under the action of the left return spring 42. The rotation process of the right support plate 3 is as follows: push the right unlocking push button 510 away from the base 1 to make the right locking pin 51 escape from the current second limiting hole 120, then rotate the right support plate 3 to the desired position along the second slide 12, then release the right unlocking push button 510, so that the right locking pin 51 is inserted into the second limiting hole 120 at another corresponding position under the action of the right return spring 52.

[0036] As described above, the base 1 is further provided with a mounting groove 13 communicating with the first slide groove 11 and the second slide groove 12 , and the mounting groove 13 allows the first sliding portion 21 and the second sliding portion 31 to be respectively installed in or removed from the first slide groove 11 and the second slide groove 12 .

[0037] And, specifically, the first slide groove 11 and the second slide groove 12 both include wide mouth portions 111, 121 and narrow mouth portions 112, 122 located outside the wide mouth portions 111, 121, and the first sliding portion 21 and the second sliding portion 31 both include wide portions 211, 311 that slide with the corresponding wide mouth portions 111, 121 and narrow portions 212, 312 that slide with the corresponding narrow mouth portions 112, 122, so that the first sliding portion 21 and the second sliding portion 31 can slide in the first slide groove 11 and the second slide groove 12 respectively and will not radially separate from the base 1. At the same time, the groove width of the installation groove 13 is greater than the width of the wide parts 211 and 311 of the first sliding part 21 and the second sliding part 31. Therefore, when the left support plate 2 or the right support plate 3 needs to be disassembled, it is only necessary to rotate the left support plate 2 or the right support plate 3 to a position where the first sliding part 21 or the second sliding part 31 is directly opposite to the installation groove 13 after releasing the lock of the left support plate 2 or the right support plate 3, and then pull out the left support plate 2 or the right support plate 3. Similarly, when the left support plate 2 or the right support plate 3 needs to be installed, it is only necessary to align the first sliding part 21 of the left support plate 2 or the second sliding part 31 of the right support plate 3 with the installation groove 13 and insert it, and then slide the first sliding part 21 or the second sliding part 31 into the first sliding groove 11 or the second sliding groove 12 accordingly.

[0038] In this embodiment, the mounting groove 13 is an open groove structure arranged on the rear side of the base 1 and opening toward the rear of the base 1. The first slide groove 11 is an arc-shaped slide groove extending horizontally from the left side of the base 1 to the rear side to the mounting groove 13. The second slide groove 12 is an arc-shaped slide groove extending horizontally from the right side of the base 1 to the rear side to the mounting groove 13.

[0039] As described above, the upper surface of the end of the left support plate 2 away from the base 1 is concavely provided with a first annular mounting groove 22, and a plurality of first limiting convex portions 221 are arranged at intervals on the outer side wall of the first annular mounting groove 22.

The left handle 6 can be detachably mounted in the first annular mounting groove 22 in a plurality of different orientations through the first annular mounting portion 61, and no matter which orientation the left handle 6 is mounted in, each first limiting groove 611 can be matched with each first limiting convex portion 221 to limit the left handle 6 in the installation orientation. When the angle of the left handle 6 needs to be adjusted, the left handle 6 only needs to be pulled out of the first annular mounting groove 22, and then the left handle 6 is switched to another orientation and then re-inserted into the first annular mounting groove 22 through the first annular mounting portion 61.

[0040] As described above, the upper surface of the end of the right support plate 3 away from the base 1 is concavely provided with a second annular mounting groove 32, and a plurality of second limiting protrusions 321 are arranged at intervals on the outer side wall of the second annular mounting groove 32. The lower end of the right handle 7 is provided with a second annular mounting portion 71, and a plurality of second limiting grooves 711 are arranged at intervals on the outer circumferential surface of the second annular mounting portion 71. The right handle 7 can be detachably mounted in the second annular mounting groove 32 in a plurality of different orientations through the second annular mounting portion 71, and no matter which orientation the right handle 7 is mounted in, each second limiting groove 711 can be matched with each second limiting protrusion 321 to limit the right handle 7 to the installation orientation. When the angle of the right handle 7 needs to be adjusted, the right handle 7 only needs to be pulled out of the second annular mounting groove 32, and then the right handle 7 is switched to another orientation and then re-inserted into the second annular mounting groove 32 through the second annular mounting portion 71.

[0041] As described above, a first circular platform 23 is formed on the inner side of the first annular mounting groove 22, and a second circular platform 33 is formed on the inner side of the second annular mounting groove 32. Hanging rings 231 and 331 are hinged in the middle of the upper surfaces of the first circular platform 23 and the second circular platform 33. The hanging rings 231 and 331 can be rotated to an upright state when in use so that the user can hook the tension rope for tension training. The hanging rings 231 and 331 can also be rotated to a flat state when not in use for storage.

[0042] As described above, the bottom surfaces of the first annular mounting portion 61 and the second annular mounting portion 71 are provided with a plurality of rollers 612, 712 spaced apart along the circumferential direction. Therefore, when the left handle 6 and the right handle 7 are removed from the first annular mounting groove 22 and the second annular mounting groove 32 respectively, the exerciser can also use the two handles as abdominal wheels.

[0043] As described above, a rubber suction cup 8 is provided at the bottom of the base 1, and a transmission rod 9 is connected to the middle of the rubber suction cup 8. The transmission rod 9 is movably arranged in the base 1, and the upper end of the transmission rod 9 passes through the upper surface of the base 1. A spring 10 is sleeved on the lower end of the transmission rod 9, and the upper end of the spring 10 abuts against the base 1, and the lower end of the spring 10 abuts against the rubber suction cup 8. The upper surface of the base 1 is provided with a U-shaped cavity 14 opened toward the front end of the base and a foot hook frame 15 that can be received in the U-shaped cavity 14. The end of the foot hook frame 15 close to the closed end of the U-shaped cavity 14 is hinged to the upper end of the transmission rod 9 through a pin 16, and the end of the foot hook frame 15 away from the closed end of the U-shaped cavity 14 is a free end and is provided with a foot hook portion 151 for hooking the feet of a human body.

[0044] The foot hook frame 15 can be turned upward to an upright state when in use, so that the exerciser can hang the two foot hooks on the foot hook frame to do sit-ups. When the foot hook frame 15 is turned upward to an upright state, on the one hand, the rubber suction cup 8 is driven by the transmission rod 9 to squeeze out the internal air and then adsorb and fix on the supporting surface (such as the ground), so that the fitness device is fixed and will not move during exercise. On the other hand, the side of the foot hook frame 15 facing the closed end of the U-shaped cavity 14 abuts against the closed end of the U-shaped cavity 14, thereby preventing the foot hook frame 15 from turning upward too much.

[0045] In addition, to ensure smooth upward flipping of the foot hook frame 15 , an arc-shaped guide surface 152 is further provided at one end of the foot hook frame 15 close to the closed end of the U-shaped cavity 14 .

[0046] The above is only a preferred embodiment of the present invention, and should not be used to limit the scope of the present invention.
