[0041] The following further explains the present utility model in conjunction with specific embodiments:

[0042] A linkage mechanism for the left and right armrests and instrument panel of a treadmill mainly consists of an instrument rod component 1, a left armrest component 2, a right armrest component 3, an instrument panel component 4, an armrest connecting rod group 5, and an instrument connecting rod group 6. The instrument rod component 1 is the base of the linkage mechanism. The instrument rod component 1 is composed of an instrument rod 11, a left connecting seat 12, a right connecting seat 13, a bushing 14, and a pressing plate 15. The left armrest component 2 is composed of a left armrest tube 21, a left rotating shaft 22, and a left limiting block 23. A left armrest connecting rod connecting seat 24 is designed on the left rotating shaft 22. The right armrest component 3 is composed of a right armrest tube 31, a right rotating shaft 32, and a right limiting block 33. A right armrest connecting rod connecting seat 34 is designed on the right rotating shaft 32. The instrument panel component 4 is usually used to display treadmill data and send user instructions. The dial component 4 is fixedly connected to the instrument connecting rod 6. The armrest connecting rod group 5 is composed of a first connecting rod 51 and a first gear 52; the instrument connecting rod group 6 is composed of a second connecting rod 61, a second gear 62, and a damping sleeve 63.

[0043] Among them, a left connecting seat 12 and a right connecting seat 13 are welded to the upper end of the instrument rod 11, and the lower end is fixed to the treadmill. The left connecting seat 12 is designed with a left rotation limiting platform 16, and the left connecting seat 12 is inserted into the bushing 14; the left armrest component 2 passes through the bushing and is connected to the armrest connecting rod group 5. A left limiting block 23 is welded to the left armrest component 2. When the left limiting block 23 of the left armrest component 2 rotates to contact the left rotation limiting platform 16 of the left connecting seat 12, the rotation stops. The rotation angle of the left armrest component 2 is generally designed to rotate within 0 - 90 degrees. The right connecting seat 13 is designed with a right rotation limiting platform 17, and the right connecting seat 13 is inserted into the bushing 14; the right armrest component 3 passes through the bushing and is connected to the armrest connecting rod group 5. A right limiting block 33 is welded to the right armrest component 3. When the right limiting block 33 of the right armrest component 3 rotates to contact the right rotation limiting platform 17 of the right connecting seat 13, the rotation stops. The rotation angle of the right armrest component 3 is generally designed to rotate within 0 - 90 degrees.

[0044] Because the left armrest component 2 and the right armrest component 3 are fixedly connected by the armrest connecting rod group 5 with bolts, the left armrest component 2 and the right armrest component 3 can rotate in conjunction. The instrument connecting rod group 6 is fixed to the left connecting seat 12 and the right connecting seat 13 through the pressure plate 15. The gear 2 62 of the instrument connecting rod group 6 is meshed with the gear 1 52 of the armrest connecting rod group 5. By designing a suitable gear rotation ratio, the armrest and the instrument panel can rotate at different angles, and the rotation of the gear can make the armrest and the instrument panel rotate in opposite directions, so that the armrest and the instrument panel can be linked to unfold and retract. Appropriate damping sleeves 63 are designed at both ends of the instrument connecting rod group 6 to adjust the rotation resistance of the entire mechanism.

[0045] The instrument rod component and the handrail component of this embodiment are not limited to round tubes; at the same time, this embodiment is not limited to using two pairs of gear structures at both ends of the connecting rod, and a pair of gear structures can also be used in the middle of the connecting rod.
