[0007] The present invention describes a height-adjustable pull-up fitness frame, such as... Figure 1 and Figure 2 As shown, it includes a counterweight frame 1, which ensures that the center of gravity of the entire device is in a low position, making the overall structure relatively stable, allowing users to exercise with peace of mind and achieve ideal fitness results.

[0008] Two vertically arranged columns 2 are installed on the counterweight frame 1. A connecting crossbar 3 is provided between the tops of the two columns 2. The connecting crossbar 3, the counterweight frame 1, and the two columns 2 form a relatively stable frame structure, thereby enhancing the stability of the overall device. A horizontally arranged support rod 4 is provided in the middle of each column 2, and a horizontally arranged top rod 5 is provided at the top of the column 2. A vertically arranged upright rod 6 is installed between the support rod 4 and the top rod 5. A guide sleeve slider 7 that can be vertically raised and lowered is installed on the upright rod 6.

[0009] The support pole 4 not only provides a mounting base for the upright pole 6, but also provides users with arm support for exercise. For example... Figure 3 and Figure 4 As shown, a handle bar 8 and a connecting plate 9 are installed on the outer side of the guide sleeve slider 7. A single lever 10 is bolted between the two connecting plates 9, and the single lever 10 can be detached from the connecting plates 9. The handle bar 8 is located on both sides of the single lever 10, allowing the user to perform wide-grip pull-ups when gripping the handle bar 8.

[0010] To achieve locking of the single lever 10 at different height positions, a sleeve 11 is fitted around the outer periphery of the single lever 10. Hooks 12 are fixedly connected to both ends of the sleeve 11 along its length. The sleeve 11 and its hooks 12 can rotate relative to the single lever 10, and rotating the sleeve 11 causes the hooks 12 to rotate synchronously without affecting the normal raising and lowering of the single lever 10. The column 2 also has several hanging holes 13 that cooperate with the hooks 12. When the hooks 12 rotate into the hanging holes 13, the single lever 10 is fixed at a designated height position on the column 2.

[0011] When the height of the single lever 10 needs to be adjusted, the user can hold the sleeve 11 and rotate it to allow the hook 12 to rotate out of the hanging hole 13. After the restriction is removed, the guide sleeve slider 7 of the single lever 10 can be vertically adjusted along the upright 6. After the adjustment is in place, rotate the sleeve 11 to allow the hook 12 to rotate into the hanging hole 13, which can achieve relative locking of the single lever 10 at the height of the upright 2. The above adjustment method is fast, convenient and has a stable limiting effect.

[0012] Furthermore, to enhance other training functions of this device, such as Figure 5 and Figure 6 As shown, grip rings 14 are attached to both ends of the sleeve 11 along its length, providing a ring-like function for users to exercise their arms. A barbell bar 15 is mounted on the outside of the connecting plate 9, with several weight plates 16 mounted on it. A foam sleeve 17 is also installed in the middle of the sleeve 11. The barbell bar 15 allows users to perform weighted squats or heavy lifting exercises. During weighted squats, the foam sleeve 17 provides protection for the user's shoulders and neck. Elastic resistance bands 18 can also be attached to the connecting plate 9 to provide upper limb stretching exercises.

[0013] To provide users with corresponding massage functions, a massage bracket 19 can be installed on the column 2. The massage bracket 19 is equipped with a vertically arranged first massage roller 20 and a horizontally arranged second massage roller 21. A horizontally arranged third massage stick 26 is installed on the column 2. The first massage roller 20 and the second massage roller 21 can massage the user's back, while the third massage stick 26 can massage the user's arms. When the user uses the first massage roller 20 for a horizontal back massage, they can also extend their arms and press them on the third massage stick 26, and sway their body from side to side to massage their back and arms simultaneously. The arms can also help support the body's balance.

[0014] In order to achieve adjustment of the height position of the second massage roller 21, such as Figure 7As shown, the massage bracket 19 has adjustable plates 22 on both sides of its bottom. Each adjustable plate 22 has a vertical groove 23 and several horizontal grooves 24 connected to the vertical grooves 23. Each horizontal groove 24 is located at a different height on the adjustable plate 22. Locking handles 25 are installed at both ends of the shaft of the second massage roller 21. Rotating the locking handles 25 locks the shaft of the second massage roller 21 within the horizontal grooves 24. A screw can be installed at the end of the locking handle 25. A screw hole is provided on the shaft of the second massage roller 21 to cooperate with the screw. When the locking handle 25 is rotated, the end face of the shaft and the end face of the locking handle 25 clamp and fix the adjustable plate 22, thus forming a limit.

[0015] When the height position of the second massage roller 21 needs to be adjusted, first loosen the locking handle 25 to release the lock on the horizontal groove 24, then move the shaft of the second massage roller 21 from the horizontal groove 24 to the vertical groove 23, and vertically move the horizontal shaft to the designated position in the horizontal groove 24 according to the height to be adjusted, and then turn the locking handle 25 to lock the shaft.

[0016] Furthermore, a support wheel 27 is installed on the column 2 on the lower side of the support rod 4, and the user can place his / her legs on the support wheel 27 for massage.

[0017] The counterweight frame 1 is designed as a rectangular frame, which is highly stable and durable. When using the first massage roller 20 and the second massage roller 21 for back exercises, if both feet are on the ground and the body pushes backward, the entire fitness frame can easily shift and deviate from its intended direction. To solve this problem, a flat base plate 28 is installed inside the counterweight frame 1. The top surface of the flat base plate 28 is flush with the top surface of the counterweight frame 1, and the flat base plate 28 can also cover the counterweight frame 1. Its length and width dimensions are the same as the counterweight frame 1. The flat base plate 28 also prevents the user from tripping over the counterweight frame 1 when leaving the fitness frame. When the user is exercising or receiving a massage on the flat base plate 28, regardless of the amplitude of their body movements, the fitness frame will not shift relative to the ground.

[0018] Furthermore, such as Figure 8 As shown, a rotatable swing arm 29 can be installed on the counterweight frame 1. One end of the swing arm 29 is provided with a vertically arranged sleeve 30, and the other end of the swing arm 29 is equipped with a rotatable turntable 31 through a bearing. A guide post 35 that cooperates with the sleeve 30 is installed on the counterweight frame 1. A vertically arranged screw is provided inside the guide post 35. One end of the screw that extends out of the guide post 35 is fitted with a cover 32 that cooperates with the sleeve 30. The sleeve 30 is located on the outer periphery of the guide post 35 between the cover 32 and the counterweight frame 1.

[0019] The cover 32 and guide post 35 are positioned to limit the movement of the sleeve 30 and guide its rotation. When the user needs to exercise using the foot pedal turntable 31, the turntable 31 can be swung to the front of the counterweight frame 1 and the front of the upright post 2 via the swing rod 29. The user can then place their feet on the turntable 31 and grip the upright post of the massage bracket 19 with both hands to rotate their body and perform waist twisting movements. The user can also grip the sleeve 11 with both hands and adjust it to a suitable height for high-arm gripping and waist twisting movements, achieving the purpose of aligning the spine and relaxing the muscles throughout the body. When the user does not need to exercise using the turntable 31, they can use their hands or feet to push the turntable 31 via the swing rod 29 to adjust it to the rear position of the counterweight frame 1, thus freeing up space on the flat base plate 28 of the counterweight frame 1 for other exercise movements.

[0020] Furthermore, such as Figure 9 As shown, both ends of the sleeve 11 along its length are connected and installed with swings 34 via hanging rings 33. The swings 34 can be hung on the single lever 10. The appropriate height of the swing can be quickly adjusted by adjusting the height of the single lever 10 to meet the user's comfort, provide the best height for people of different heights, and increase the fun of exercise.

[0021] Furthermore, such as Figure 10 As shown, a detachable long shaft 36 is installed at the axial position of the second massage roller 21. Both ends of the long shaft 36 are provided with screw holes. The screw on the locking handle 25 is engaged with the screw holes. A long shaft sleeve 37 is fitted around the outer periphery of the long shaft 36. Spacers 38 are fitted at both ends of the long shaft sleeve 37 that extend out of the second massage roller 21. The spacers 38 are engaged between the second massage roller 21 and the adjusting plate 22. Rotating the locking handle 25 can clamp and fix the adjusting plate 22 with the spacers 38 without affecting the relative rotation of the second massage roller 21.

[0022] Furthermore, such as Figure 11 As shown, a spacer 38 can also be installed on the rotating shaft of the first massage roller 20. The vertical height position of the first massage roller 20 can be adjusted by the spacer 38. The spacer 38 can be installed at the upper or lower end of the first massage roller 20 according to the needs of the exerciser, so as to realize the installation of the first massage roller 20 at different height positions on the massage bracket 19.

[0023] Furthermore, such as Figure 12As shown, a reinforcing column 39 can also be installed at the bottom of the massage bracket 19. The reinforcing column 39 is fixedly connected to the bottom counterweight frame 1. The reinforcing column 39 can improve the overall stability of the fitness frame, solve the resonance of the double column fitness frame, and prevent the rings and barbell plates from shaking when the double column fitness frame is in use. In addition, the structure is relatively sturdy and durable from the appearance, giving people a visual aesthetic, and also providing an installation position for the adjustment plate 22 of the massage axis, increasing the strength.

[0024] The height-adjustable pull-up fitness frame described in this utility model also has the following advantages: Multifunctional Exercise: In addition to basic pull-up bar exercises, this invention integrates various fitness accessories such as a barbell bar 15, elastic ropes 18, as well as grip rings 14 and a swing 34, providing users with a variety of exercise options.
