[0024] like Figure 1-Figure 5 As shown, the walking machine column locking mechanism 100 provided by the present invention includes a first member 1 fixed to the walking machine frame, a second member 2 fixed to the walking machine column, and a third member 3 movably disposed between the first and second members 1 and 2. The first member 1 is provided with a first receiving slot 10. The third member 3 includes a connecting rod 31, a wrench 32 rotatably connected to the connecting rod 31, and a movable member 33 partially received in the first receiving slot 10. The movable member 33 includes a protrusion 331 that protrudes into the first receiving slot, a main body 330 connected to the protrusion 331, and a spring 332 located at an end of the main body 330 away from the protrusion 331. When the protrusion 331 is pressed downward by a force toward the first receiving slot 10, the spring 332 abuts against the bottom of the first receiving slot 10. When the spring 332 is free of force, the protrusion 331 protrudes out of the first receiving slot 10, allowing the second member 2 to rotate relative to the first member 1.

[0025] Specifically, the second member 2 is rotatably connected to the first member 1 via a screw 4. The second member 2 is provided with a second receiving groove 21 that can enclose a first receiving space with the first receiving groove 10, and a third receiving groove 22 that can enclose a second receiving space with the first receiving groove 10. When the spring 332 is not under force, the movable member 3 can move between the second receiving groove 21 and the third receiving groove 22. In other words, when the upright post of the treadmill is erected to an open state, the movable member 3 is located in the first receiving space enclosed by the second receiving groove 21 and the first receiving groove 10. When the upright post of the treadmill is rotated toward the base of the treadmill to a folded state, the movable member 3 is located in the second receiving space enclosed by the third receiving groove 22 and the first receiving groove 10.

[0026] In this embodiment, the main body 330 includes a first part 333 connected to the protrusion 331 and a second part 334 connected to the spring 332. The thickness of the first part 333 is less than the thickness of the protrusion 331, and the width of the second part 334 is greater than the width of the protrusion 331. The first receiving groove 10 includes a front groove 101 for accommodating the first part 333 and a rear groove 102 for accommodating the second part 334. The distance that the second part 334 can move in the rear groove 102 is equal to the distance that the protrusion 331 can move in the front groove 101.

[0027] Preferably, the first portion 333 is generally fan-shaped, with the width of the first portion 333 at the end near the protrusion 331 being greater than the width of the first portion 333 at the end near the second portion 334. The width of the open end of the front slot 101 of the first receiving slot 10 is also greater than the width of the end of the front slot 101 that connects to the rear slot 102. In other words, the slightly inclined sidewall of the front slot 101 extending toward the rear slot 102, combined with the generally fan-shaped first portion 333, prevents the column from shaking during locking, ensuring safety and stability.

[0028] In this embodiment, the first component 1 includes a through hole 103 for accommodating the screw 4 and a limiting column 104 located on the reverse extension line of the line connecting the center of the through hole 103 and the center of the first receiving groove 10. The second component 2 is provided with a sliding groove 23 corresponding to the limiting column 104. When the second component 2 rotates relative to the first component 1, the limiting column 104 moves in the sliding groove 23.

[0029] In this embodiment, the wrench 32 includes an abutment portion 321 connected to the connecting rod 31 and a tail portion 322 away from the connecting rod 31. When the wrench 32 rotates close to the first component 1, the abutment portion 321

[0030] The spring 332 abuts against the protrusion 331 and compresses the spring 332, causing the protrusion 331 to enter the front groove 101. A stopper 24 is provided between the second receiving groove 21 and the third receiving groove 22 of the second member 2. When the protrusion 331 is located in the front groove 101, the stopper 24 blocks the protrusion 331, preventing the second member 2 from rotating relative to the first member 1. The angle between the two side walls of the stopper 24 is approximately equal to the angle through which the second member 2 can rotate relative to the first member 1.

[0031] The utility model provides a walking machine column locking mechanism, comprising a first member fixed to the walking machine frame, a second member fixed to the walking machine column, and a third member movably disposed between the first and second members. The first member is provided with a first receiving groove, and the third member includes a connecting rod, a wrench rotatably connected to the connecting rod, and a movable member partially received in the first receiving groove. The movable member includes a protrusion that can protrude into the first receiving groove, a main body connected to the protrusion, and a spring located at an end of the main body away from the protrusion. When the spring is not under load, the second member can rotate relative to the first member. The relative movement between the first and second members is limited by the position change of the movable member, which is convenient for operation and safe and stable.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
