Description

Technical Field

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

[0002] The anti-gravity treadmill includes a pair of uprights, a treadmill platform positioned at the base of the uprights, a main control panel mounted on the uprights, and a pair of handrails on the main control panel. A screw mechanism connects the main control panel to the uprights, with the screw and nut of the mechanism providing a fixed connection. The screw is housed within the uprights and driven by a motor. The motor shaft is connected to the screw via a coupling, which transmits power from the motor to the coupling, which in turn transmits power to the screw. This power transmission process requires a stable support structure. Utility Model Content

[0003] The technical problem solved by this utility model is: in the anti-gravity running platform, the lead screw mechanism used for lifting the main control panel requires a stable support structure for the motor to transmit power to the lead screw.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a support structure for the motor power transmission of a lead screw mechanism for lifting the main control console of an anti-gravity running platform, including a back plate and a support. The back plate is welded into the column of the anti-gravity running platform, and the support is installed on the back plate through a threaded connector. The support is U-shaped, the motor is installed at the bottom of the support, a coupling is set in the support, a bearing is installed at the top of the support, the bearing is matched on the lead screw, and the bottom end of the lead screw is connected to the motor shaft through the coupling.

[0005] According to the above technical solution, the motor is installed at the bottom of the support, the support is installed on the back plate, and the back plate is welded into the column, thus the motor is stably fixed.

[0006] According to the above technical solution, the lead screw is pivotally connected to the top of the support via a bearing. The support is installed on the back plate, and the back plate is welded into the column. Therefore, the connection end between the lead screw and the motor shaft is stably positioned.

[0007] With the motor and one end of the lead screw stably positioned, the coupling can reliably transmit the motor's power to the lead screw.

[0008] The back plate has threaded holes, the support has connection holes, and the back of the support has a limiting protrusion. When the limiting protrusion abuts against the bottom of the back plate, the threaded hole and the connection hole are aligned. The long bolt is fitted into the connection hole and the threaded hole to fix the support to the back plate.

[0009] The support has a protrusion at the front, the height of which is greater than or equal to the height of the long bolt head. The cover plate of the column is fixed to the protrusion by a connector. Because the height of the protrusion is greater than or equal to the height of the long bolt head, the cover plate will not interfere with the head of the long bolt, and the cover plate can cover the entire support, making the support hidden in the column.

[0010] The support has an upper bearing stop at the top and a lower bearing stop below the top. The upper bearing stop abuts against the top of the bearing outer ring, and the lower bearing stop abuts against the bottom of the bearing outer ring. The upper and lower bearing stop are connected by a threaded connector. The bearing inner ring is fitted onto a lead screw.

[0011] The lower limit component of the bearing is provided with an upwardly protruding annular structure. A step is formed between the upwardly protruding annular structure and the body of the lower limit component of the bearing. The upwardly protruding annular structure fits into the bearing hole at the top of the support and abuts against the bottom of the outer ring of the bearing.

[0012] The support has a recessed structure at its top, within which the bearing upper limit positioning component fits. This allows the bearing upper limit positioning component to be effectively positioned and to abut against the top of the bearing outer ring. Furthermore, the thickness of the support top can be increased to enhance the support's strength.

[0013] The technical effects of this utility model are as follows: First, the motor and the lead screw power end are stably positioned in the column of the anti-gravity running platform; second, the motor stably transmits power to the lead screw through the coupling. Attached Figure Description
