Description

Technical Field

[0001] This utility model relates to the field of gymnastics bars, and more particularly to a foldable gymnastics bar. Background Technology

[0002] Gymnastics bars are a general term for various equipment, gear, and supplies used in sports competitions and fitness exercises. Especially for teenagers, physical exercise is very important, and gymnastics bars are a common type of sports equipment used in gymnastics.

[0003] The existing Chinese patent CN214550861U, disclosed on November 2, 2021, is an adjustable gymnastic ring bar, including a support frame, a vertical rod, a telescopic rod, a horizontal rod, hanging ropes, hanging rings, and a two-way adjustment mechanism. This invention achieves the advantage of simultaneously adjusting two hanging rings by setting a two-way adjustment mechanism at the upper end of the horizontal rod, where a winding wheel winds the pull rope, causing the pull ropes at both ends to drive the left and right moving blocks to move towards the center inside the mounting frame. Furthermore, by setting a rotating mechanism at the upper end of the two-way adjustment mechanism, a knob drives a worm gear through a rotating shaft, causing the worm gear to drive a rotating rod and a winding wheel through a worm wheel, thus enabling the winding wheel to wind and pull the pull rope, achieving the advantage of quickly rotating the winding wheel.

[0036] Reference Figures 1-6 A foldable gymnastics bar includes a gymnastics activity adjustment bar, a gymnastics support placement frame, a folding support mechanism, a rotating folding mechanism, and a folding anti-loosening mechanism.

[0037] Two gymnastics support racks are symmetrically mounted on the gymnastics movement adjustment bar. The height of the gymnastics movement adjustment bar can be adjusted between the two support racks, allowing for different height positions. The gymnastics movement adjustment bar is supported by the two support racks. A folding support mechanism is symmetrically mounted on the lower end of each gymnastics support rack. The folding support mechanism can fold upwards from the lower end of the support rack, effectively reducing space occupation and facilitating placement. A rotating folding mechanism is installed between the support rack and the folding support mechanism. The rotation of the folding mechanism effectively prevents the support rack and the folding support mechanism from folding arbitrarily. A folding anti-loosening mechanism is installed and connected to the outer end of the support rack. The folding anti-loosening mechanism can unfold and clamp on the outside of the support rack, thus ensuring stable placement of the folding support mechanism during folding and preventing it from loosening.

[0038] Reference Figures 1-4 In a preferred embodiment, the gymnastics activity adjustment bar includes a middle grip bar 1, which is convenient for personnel to hold and operate. Connecting bar sleeves 11 are sleeved around both ends of the middle grip bar 1, which can be effectively inserted. The connecting bar sleeves 11 and the middle grip bar 1 are fixedly connected by positioning screws 12. When the positioning screws 12 are loosened, the connecting bar sleeves 11 and the middle grip bar 1 can be disassembled and replaced. A movable support arm 2 is fixedly connected to the lower end of the connecting bar sleeve 11. The connecting bar sleeve 11 can be supported and placed by the movable support arm 2. A gymnastics support placement frame is installed around the movable support arm 2. The movable support arm 2 can be adjusted and supported on the gymnastics support placement frame.

[0039] The inner side of the movable support arm 2 is provided with an adjustment hole for adjusting the height of the plug 21, so as to facilitate adjustment.

[0040] The gymnastics support frame includes a bottom connecting plate 6, with two geometric frames 4 fixedly connected to both ends of the bottom connecting plate 6. The bottom connecting plate 6 can drive the two geometric frames 4 to be placed symmetrically. Folding support mechanisms are movably installed on the inner sides of both ends of the geometric frames 4. The folding support mechanisms can be positioned and rotated in the grooves of the geometric frames 4. A fixed support arm 3 is fixedly connected to the middle of the upper end of the geometric frames 4. The geometric frames 4 can support the fixed support arm 3 for placement. An adjusting plug 21 is inserted into the inner side of the upper end of the fixed support arm 3. It can be effectively inserted and positioned during adjustment. A locking bolt 22 is threaded and rotated on the fixed support arm 3 below the adjusting plug 21, so as to effectively lock and fix it. A folding anti-loosening mechanism is fixedly connected to the outer end of the movable support arm 2. The folding anti-loosening mechanism can abut and clamp on the outer side of the movable support arm 2.

[0041] The folding support mechanism includes a connecting arm plate 52, with placement arm plates 5 fixedly connected to both ends of the connecting arm plate 52. The connecting arm plate 52 can drive the two placement arm plates 5 to be placed symmetrically and stably. The outer end of the placement arm plate 5 is fixedly connected to an anti-slip rubber sleeve 51. The rubber material of the outer end anti-slip rubber sleeve 51 effectively prevents slippage during placement. The inner end of the placement arm plate 5 is sleeved in the lower end groove of the geometric frame 4. The placement arm plate 5 can be positioned and rotated in the lower end groove of the geometric frame 4. The placement arm plate 5 and the geometric frame 4 are movably connected by a fourth pin 41, thereby enabling stable positioning and rotation.

[0042] Reference Figures 1-6 In a preferred embodiment, the folding anti-loosening mechanism includes a T-slot positioning sleeve 8. A fixed support arm 3 is fixedly connected to the inner end of the T-slot positioning sleeve 8, allowing the T-slot positioning sleeve 8 to be stably fixed on the fixed support arm 3. A T-shaped rotating column 82 is rotatably mounted on the inner side of the outer end of the T-slot positioning sleeve 8, allowing the T-shaped rotating column 82 to be positioned and rotated within the T-slot positioning sleeve 8. A rotating connecting plate 81 is fixedly connected to the outer end of the T-shaped rotating column 82, enabling the T-shaped rotating column 82 to drive the rotating connecting plate 81 to rotate. A lifting handle 84 is fixedly connected to the outer side of the movable end of the rotating connecting plate 81 for the user to grip. The lifting handle 84 facilitates the rotation of the rotating connecting plate 81. An abutment spring 831 is fixedly connected to the inner side of the movable end of the rotating connecting plate 81. The rotating connecting plate 81 can elastically abut against the abutment spring 831. A rubber soft sleeve 83 is fixedly connected to the periphery of the abutment spring 831 on the rotating connecting plate 81. The abutment spring 831 can elastically abut against the rubber soft sleeve 83. When rotated and unfolded, the rubber soft sleeve 83 is located on the outer side of the placement arm plate 5. When the person squeezes the rubber soft sleeve 83, it causes the abutment spring 831 to deform, thereby effectively rotating the outer side of the placement arm plate 5 to abut against the abutment.

[0043] The rotating folding mechanism includes a rotating inner arm 7, with a wrapping arm 73 sleeved around the upper circumference of the rotating inner arm 7. The rotating inner arm 7 and the wrapping arm 73 are movably connected by a second pin 74, allowing for folding. The rotating inner arm 7 and the wrapping arm 73 are fixedly connected by a positioning shaft 75, which effectively positions the arm during support. Third positioning rotating plates 77 are installed on both sides of the upper end of the rotating inner arm 7, and are movably connected to the rotating inner arm 7 and the third positioning rotating plates 77 by a third pin 76, allowing the rotating inner arm 7 to rotate and be positioned between the two third positioning rotating plates 77. The third positioning rotating plates 77 are fixedly connected to the fixed support arm 3 for stable placement. First positioning rotating plates 72 are installed on both sides of the lower end of the rotating inner arm 7, and are movably connected to the rotating inner arm 7 and the first positioning rotating plates 72 by a first pin 71, allowing for folding and positioning. The first positioning rotating plates 72 are fixedly connected to the placement arm plate 5 for stable placement.

[0044] Working principle: During use, the height of the gymnastics activity adjustment bar can be adjusted between the two gymnastics support racks, allowing for different height positions. The gymnastics activity adjustment bar can be supported by the two gymnastics support racks. The folding support mechanism can be folded at the lower end of the gymnastics support racks. Folding upwards can effectively reduce space occupation and facilitate placement. By rotating the support of the folding mechanism, the gymnastics support racks and folding support mechanism can be effectively prevented from folding arbitrarily. The folding anti-loosening mechanism can be unfolded on the outside of the gymnastics support racks to clamp, so that the folding support mechanism can be placed stably when folded and placed, preventing it from loosening and unfolding.

[0045] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
