Utility Model Content

Based on this, the purpose of the utility model is to provide a physical exercise arm trainer to solve the technical problem that the trainer is not well adapted to the height of the user.

To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a physical exercise arm trainer, comprising a chassis, a telescopic rod connected to the top of the chassis, a table top connected to the top of the telescopic rod, a support shaft passing through the table top, a disc and a screw rod connected to both ends of the support shaft respectively, a support disc and a gear are sleeved on the outside of the support shaft, a screw rod passes through the side of the support shaft, a hand wheel and a limit plate are connected to both ends of the screw respectively, a guide rod is fixedly connected to the side of the limit plate, a fixed block is connected under the table top, a motor is installed on the fixed block, and a threaded sleeve is connected to the side of the telescopic rod through the fixed rod.

By adopting the above technical solution, after the staff rotates the handwheel, the screw and the guide rod cooperate to make the limit plate move and fit the lead screw. After the motor is started, the output end drives the support shaft to rotate through the meshing of two gears. The rotation of the support shaft drives the limit plate to rotate. At this time, the friction between the limit plate and the lead screw drives the lead screw to rotate. After the lead screw rotates, it cooperates with the telescopic rod and the threaded sleeve to drive the table to rise and fall. After adjusting to the appropriate height, the user turns off the device. After the height adjustment of the trainer is completed, the user reverses the handwheel to make the limit plate move away from the lead screw. At this time, the support shaft no longer drives the lead screw to rotate, and the table stops rising and falling. The user holds the gripping rod and pushes the disc to rotate for rehabilitation exercise. The output end of the motor can also drive the two gears to mesh to make the support shaft rotate. The support shaft drives the disc and the gripping rod to move, and then drives the user's arm to move to achieve the effect of rehabilitation exercise. After the exercise, the motor is turned off, and the use is completed.

Furthermore, the disc is connected with a grip rod, and a cavity is provided inside the support shaft.

By adopting the above technical solution, the telescopic rod is extended and retracted to change the height of the table top, and the support shaft drives the disc and the handle to move.

Furthermore, the support shaft is rotatably connected to the table top, and the screw rod is rotatably connected to the support shaft.

By adopting the above technical solution, after the motor is started, the output end drives the support shaft to rotate through the meshing of two gears, and the rotation of the support shaft drives the limit plate to rotate.

Furthermore, there are two support plates, and the two support plates are symmetrically distributed.

By adopting the above technical solution, the two support plates fix the support shaft to prevent the support shaft from falling.

Furthermore, the limiting plate abuts against the screw rod, and the screw rod is threadedly connected to the support shaft.

By adopting the above technical solution, after the screw rod rotates, it cooperates with the telescopic rod and the threaded sleeve to drive the table top to rise and fall.

Furthermore, there are four telescopic rods, and the four telescopic rods are distributed in a rectangular array.

By adopting the above technical solution, the four telescopic rods are distributed in a rectangular array and have stability.

Furthermore, the limiting plate is in an arc shape, and the inner diameter of the limiting plate is equal to the diameter of the top of the screw rod.

By adopting the above technical solution, the screw rod is driven to rotate by the friction force between the limit plate and the screw rod.

In summary, the utility model mainly has the following beneficial effects:

1. The utility model is provided with a telescopic rod, a gear, a screw, a limit plate, a guide rod, a threaded sleeve and a screw rod. After the hand wheel is rotated, the limit plate is displaced and fits the screw rod through the cooperation of the screw rod and the guide rod, thereby achieving the purpose of connecting the support shaft with the screw rod. After the motor is started, the output end drives the support shaft to rotate through the meshing of two gears. Since the support shaft and the screw rod are in a connected state at this time, the screw rod can be rotated when the support shaft rotates. Since the threaded sleeve is fixed, the screw rod will move upward, and then the telescopic rod and the table top will move upward synchronously, which is convenient for adjusting the height to adapt to users of different heights. The structure is simple and convenient to use.
