Description

Technical Field

[0001] This utility model relates to the field of medical rehabilitation equipment, specifically to an anti-gravity treadmill. Background Technology

[0002] The main structure of the anti-gravity treadmill includes a pair of uprights, a treadmill connected to the uprights, handrails mounted on the uprights, and an inflatable cushion above the treadmill. To accommodate users of different heights, a locking mechanism is installed between the handrails and the uprights, with locking holes on the uprights. When adjusting the handrail height, the user raises the swing arm on the handrail frame. The swing arm swings upward, unlocking the locking mechanism, which disengages from the locking holes on the uprights, allowing the handrail frame to rise and fall freely along the uprights. When the handrail reaches the appropriate height, the swing arm needs to be released to return to its original position so that the locking mechanism can re-insert into the corresponding locking holes to fix the handrail frame's height on the uprights. However, the integrated handrail frame and handrail structure are quite heavy. When the user releases the swing arm, the handrail frame descends linearly along the uprights under gravity, and the locking mechanism may not have enough time to insert into the corresponding locking holes on the uprights. Utility Model Content

[0003] The technical problem solved by this utility model is as follows: When adjusting the height of the handrail, the user lifts the swing frame on the handrail frame, the swing frame swings up and unlocks the locking pin structure, and the locking pin structure disengages from the lock hole of the column; after the handrail frame freely rises and falls along the column to a suitable height, the user releases the swing frame, and under the action of gravity, the handrail frame descends linearly along the column, and the locking pin structure does not have time to insert into the corresponding lock hole of the column.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an anti-gravity running platform lifting platform with an unlocking and lifting structure, including a handrail frame, a handrail fixedly connected to the handrail frame, sliders arranged on both sides of the handrail frame, a locking pin structure arranged on the handrail frame, and a swing frame for unlocking the locking pin structure. The sliders cooperate with the vertical guide rails on the column. The locking pin structure includes a rotating shaft pivotally connected to the handrail frame, a connecting rod connected to the rotating shaft, and a locking pin hinged to the connecting rod. The locking pin is movably inserted into the side wall of the handrail frame and can protrude outward from the side wall of the handrail frame to cooperate with the locking hole on the column. The swing frame is fixedly connected to the rotating shaft, and a handle is provided on the side of the swing frame, which is fixedly connected to the handrail frame.

[0005] According to the above technical solution, the user raises the swing frame upwards, causing it to swing relative to the handrail frame. This drives a pair of rotating shafts on both sides of the swing frame to rotate, simultaneously unlocking the locking pin structures on the left and right sides. The user raises or lowers the handrail frame to adjust its height. After adjustment, the user grips the handle to release the swing frame, which remains stationary while the swing frame returns to its original position. Simultaneously, the swing frame drives the pair of rotating shafts to rotate in opposite directions, causing the locking pins of the left and right locking pin structures to insert into the lock holes of the left and right pillars, respectively, thus locking the handrail frame and handrail in place.

[0006] The handrail frame has an upright plate, a rotating shaft is pivotally connected to the upright plate, a swing frame is fixedly connected to the end of the rotating shaft, and a handle is mounted on a handle frame, which is fixedly installed on the upright plate. Specifically, the swing frame is fixedly connected to the end of the rotating shaft by fastening bolts, and the handle frame is fixedly installed on the upright plate by a pair of bolts.

[0007] The upright plate is equipped with an upright plate tension spring seat, and the swing frame is equipped with a swing frame tension spring seat. A tension spring is installed between the swing frame tension spring seat and the upright plate tension spring seat. When the swing frame swings upward, the tension spring is stretched, and the handrail frame is unlocked from the upright. When the user releases the swing frame, the tension spring releases its elastic potential energy, the swing frame swings downward to return to its original position, and the relative position of the handrail frame and the upright is locked.

[0008] The swing frame includes a pair of side plates and connecting rods that connect the pair of side plates. The pair of side plates are fixedly connected to a pair of rotating shafts in a one-to-one manner. The user raises the handrail by holding the connecting rods.

[0009] A limiting block is fixedly installed on the upright plate. The limiting block includes a first limiting surface and a second limiting surface. When the swing frame swings downward, it can abut against the first limiting surface. When the swing frame swings upward, it can abut against the second limiting surface. When it abuts against the first limiting surface, the swing frame reaches the limit position of its downward swing. When it abuts against the second limiting surface, the swing frame reaches the limit position of its upward swing.

[0010] The back of the handrail is fitted with a back panel, which has a clearance groove. The handrail and the side panel fit into the clearance groove.

[0011] Compared to existing technologies, the handrail of this invention allows the user's hand to move freely up and down along the column to a suitable height. The user's hand then moves from the swing frame to the side handle, releasing the swing frame and gripping the handle. In this way, when the handrail remains stationary, the locking pin structure engages with the locking hole of the column to lock the height of the handrail, preventing the handrail from descending linearly along the column under gravity, thus avoiding the locking pin structure not having enough time to insert into the corresponding locking hole of the column.
