Treadmill frame for realizing folding and slope lifting of treadmill platform

A treadmill frame for realizing folding and slope lifting of a treadmill platform, comprising a treadmill platform (1), a base (2), a bracket (3), a telescopic rod (4) and a switch piece (5);

• a running belt (6) is arranged at a front and back of the treadmill platform (1);
• the base (2) is under the treadmill platform (1) and is configured to fall on a ground;
• a bottom end of the bracket (3) is pivoted on the base (2), and a top end of the bracket (3) is tilted backward and pivoted on a front half of the treadmill platform (1);
• one end of the telescopic rod (4) is pivoted on the base (2), and a pivot point of the telescopic rod (4) and the base (2) is located behind a pivot point of the bracket (3) and the base (2), the other end of the telescopic rod (4) is pivoted on the treadmill platform (1), and a pivot point of the telescopic rod (4) and the treadmill platform (1) is located in front of a pivot point of the bracket (3) and the treadmill platform (1), so as to form a cross between the bracket (3) and the telescopic rod (4);
• the switch piece (5) is configured to pivotally connect a front end of the treadmill platform (1) on the base (2) or loosen the front end of the treadmill platform (1) from the base (2), and a rotation shaft is coaxial with a rotation shaft of the bracket (3) pivoted on the base (2), and is located in front of the pivot point of the treadmill platform (1) and the telescopic rod (4).
