Detailed Implementation

[0016] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.

[0017] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "bottom", "top", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] Please refer to Figure 1-3This embodiment provides a quick-release locking structure for the telescopic uprights of a treadmill, including a bent tube 1, uprights 2, and a quick-release locking structure. The bent tube 1 is a hollow U-shaped tube used to connect the left and right uprights 2. The middle section of the bent tube 1 is used to install and connect instruments such as dashboards and electronic watches, and can also be used as a handrail. The outer side of the bent tube 1 is provided with scales, and the bottom of the bent tube 1 is provided with a limiting sleeve 3. The limiting sleeve 3 is a convex sleeve, with one small end fitted into the bent tube 1 and the large end fitted into the upright 2 to prevent swaying. The upright 2 is a hollow column, with the lower end connected to the treadmill frame and the upper end provided with a connecting part 5 and several limiting holes 4. The cross-section of the connecting part 5 is U-shaped, and the U-shaped opening of the connecting part 5 is provided with a vertical opening groove 6 for stress relief and to facilitate clamping by the quick-release locking structure.

[0019] The quick-release locking structure includes a sleeve 7, a quick-release head 8, a screw 9, a fixing seat 10, a bushing 11, and an arc-shaped piece 12. The sleeve 7 is a U-shaped piece with a connecting hole 13 at the opening. The quick-release head 8 has an arc-shaped handle 14, with a hinge hole 15 at one end and an arc-shaped cam structure on the outside of the hinge hole 15. The screw 9 is located in the connecting hole 13 of the sleeve 7, with one end screwed to the fixing seat 10 and the other end hinged to the hinge hole 15 of the handle 14. The fixing seat 10 has a central... The bushing 11 has a through hole with an internal thread in the center. The upper opening of the bushing 11 has a limiting part 16 and several adapting grooves 17 to facilitate the compression and locking of the bent tube 1. The bushing 11 also has several limiting posts 18, the number and position of which correspond to the limiting holes 4 at the upper end of the column 2. One side of the limiting post 18 has a chamfer to facilitate insertion into the limiting hole 4. The limiting post 18 has a U-shaped hollow around it. The arc-shaped piece 12 has a through hole and an arc-shaped groove. The arc-shaped groove facilitates the rotation of the outer arc cam of the handle 14.

[0020] This embodiment provides a treadmill column telescopic quick-release locking structure. During installation, the bent tube 1 is fitted into the bushing 11, the limiting sleeve 3 is fitted into the bent tube 1, the bushing 11 is fitted into the column 2, and the sleeve 7 is fitted onto the outside of the connecting part 5 of the column 2. The screw 9 passes through the arc-shaped piece 12, then through the two connecting holes 13 of the sleeve 7, and is screwed into the fixing seat 10. Rotating the handle 14 of the quick-release head 8 drives the screw 9 to rotate. After rotating to a suitable tightness, the quick-release head 8 is moved so that the thicker part of the arc cam structure of the quick-release head 8 presses against the arc-shaped piece 12 to complete the clamping and fixing. When the height needs to be adjusted, the two quick-release heads 8 are moved to rotate the arc cam of the quick-release head 8, loosening the clamping structure. The bent tube 1 is moved inside the column 2. After adjusting to a suitable height, the quick-release head 8 is moved to rotate the arc cam of the quick-release head 8 to clamp and complete the adjustment.
