[0029] The utility model embodiment provides a column folding mechanism, combined with Figure 1-9 As shown, it includes a body component, a locking and unlocking component and a column component rotatably connected to the body component, the column component is provided with a latch 41, the body component is provided with a plurality of sockets 21 adapted to the latch 41, the sockets 21 are distributed on the rotation track of the latch 41, the locking and unlocking component is used to lock / unlock the column component, when the column component is in a locked state, the latch 41 is inserted into the socket 21 for positioning; when the column component is in an unlocked state, the latch 41 can move in a direction away from the socket 21, so that an external force can drive the column component to rotate.

[0030] The column folding mechanism of the utility model is provided with a latch 41 on the column assembly, and a plurality of insertion holes 21 on the body assembly, and the insertion holes 21 are distributed on the rotation track of the latch 41, so that the column assembly can be rotated and folded relative to the body assembly. The structure is simple and stable, not easy to be damaged, and can save space while meeting the different usage habits of customers.

[0031] like Figure 1 As shown, in this embodiment, the left and right ends of the column 3 are integrated, so when both the left and right ends of the column 3 are in the unlocked state, the user can drive the column 3 to rotate and fold. When the user uses the treadmill, the column 3 can be used upright or folded by the column folding mechanism. In this embodiment, the rotation angle of the column 3 relative to the horizontal plane is 0-90°.

[0032] In this embodiment, a control component (not shown) is provided in the treadmill, and the control component includes a gyroscope, which is used to detect the angle between the column 3 and the horizontal plane. When the gyroscope detects that the column 3 is in an upright state, the control component controls the treadmill's walkway to automatically change speed to a running mode of 1-10 km / h; when the gyroscope detects that the column 3 is in a folded state, the control component controls the treadmill's walkway to automatically change speed to a walking mode of 1-6 km / h.

[0033] The body assembly includes a body 1 and a fixing member 2 fixedly connected to each other, the jack 21 is arranged on the fixing member 2, the column assembly includes a column 3 and a rotating member 4 fixedly connected to each other, and the latch 41 is arranged on the rotating member 4.

[0034] In this embodiment, the fixing member 2 and the body 1 are fixed by welding, and the rotating member 4 and the column 3 are fixed by welding. The pin 41 is columnar, and the socket 21 is a round hole, and the diameters of the pin 41 and the socket 21 are adapted to each other. The body 1 is fixed, and when the column 3 rotates around the body 1, the rotating member 4 rotates around the fixing member 2. When the pin 41 is inserted into the socket 21, the rotating member 4 and the fixing member 2 fit together, and the rotating member 4 cannot rotate relative to the fixing member 2, thereby fixing the position between the column 3 and the body 1. In other embodiments, the fixing member 2 and the body 1 can also be integrally formed, and the rotating member 4 and the column 3 can also be integrally formed.

[0035] There may be one latch pin 41 and two insertion holes 21 , and the two insertion holes 21 are respectively located at the starting point and the end point of the rotation path of the latch pin 41 .

[0036] like Figure 5 and 7As shown, in this embodiment, the fixed part 2 and the rotating part 4 are both approximately circular, and there are two latches 41 that are symmetrically distributed on both sides of the center of the rotating part 4. The provision of two latches 41 can make the force more uniform and the structure more stable. There are four sockets 21 that are symmetrically distributed on the fixed part 2, and the center line of the four sockets 21 forms a square. The two sockets 21 located on the diagonal of the square form a group, and the four latches 41 form two groups, which are respectively adapted to the fixed positions of the latches 41 at two rotation angles.

[0037] The fixing member 2 is provided with a first limiting opening 22 , and the rotating member 4 is provided with a first limiting block 42 . The first limiting block 42 slides in the first limiting opening 22 . The first limiting opening 22 is used to limit the rotation angle of the column assembly.

[0038] like Figure 5 and 7 As shown, in this embodiment, the first limiting opening 22 is provided at the edge of the fixing member 2 and is arc-shaped, and the side walls at both ends of the first limiting opening 22 provide limiting functions for the first limiting block 42. When the column 3 is in the unlocked state, the user rotates the column 3, and when the first limiting block 42 abuts against any one end of the side wall of the first limiting opening 22, it means that the rotation angle of the column 3 has reached the limit, and at this time, the locking column 3 can make the column 3 stand up or fold up.

[0039] The locking and unlocking assembly includes a handle 5, a first locking portion 31 is provided on the column 3, a second locking portion 51 is provided on the handle 5, an unlocking groove 311 is provided on the first locking portion 31, and a locking block 511 is provided on the second locking portion 51; when the handle 5 is rotated so that the locking block 511 enters the unlocking groove 311, the column assembly is in an unlocked state.

[0040] like Figure 8 and 9 As shown, in this embodiment, there are two locking blocks 511 and two unlocking grooves 311. The first locking portion 31 is recessed inwardly on one side of the column 3, and the second locking portion 51 is protruding on one side of the handle 5. The unlocking groove 311 is recessed on the first locking portion 31, and the unlocking groove 311 is located at the lowest point in the horizontal direction of the first locking portion 31. The locking block 511 is protruding on the second locking portion 51. Both the locking block 511 and the unlocking groove 311 are provided with matching guide surfaces. When the user rotates the handle 5, the locking block 511 slides out of the unlocking groove 311 under the action of the guide surface. At this time, the column assembly is locked relative to the body 1 and cannot rotate.

[0041] An accommodating cavity 6 is formed between the fixing member 2 and the rotating member 4 . A spring 61 is installed in the accommodating cavity 6 . Two ends of the spring 61 abut against the machine body 1 and the first locking portion 31 , respectively.

[0042] like Figure 4 As shown, the spring 61 provides a reset function for the locking and unlocking assembly. When the user rotates the handle 5 to make the locking block 511 leave the unlocking slot 311, the spring 61 is in a compressed state; when the user rotates the handle 5 to make the locking block 511 rotate to the position corresponding to the unlocking slot 311, the column assembly moves a short distance toward the handle 5 under the action of the spring 61, so that the locking block 511 and the unlocking slot 311 are engaged. At this time, the pin 41 and the socket 21 are separated, and the column 3 can be rotated and folded.

[0043] The column 3 is provided with a second limit block 32 , and the handle 5 is provided with a second limit opening 52 . The second limit block 32 is suitable for sliding in the second limit opening 52 , and the second limit opening 52 is used to limit the rotation angle of the handle 5 .

[0044] like Figure 2 , 8 As shown in FIGS. 9 and 10 , in this embodiment, the second limit block 32 is protruded from the lower end of the column 3 , the second limit opening 52 is arranged at the edge of the handle 5 and is arc-shaped, and the side walls at both ends of the second limit opening 52 provide a limiting function for the second limit block 32 .

[0045] When the lock block 511 leaves the unlocking slot 311, the locking and unlocking assembly locks the column assembly, and the second limit block 32 abuts against the side wall of one end of the second limit opening 52, indicating that the handle 5 is in a locked state and the column 3 cannot rotate. When the user rotates the handle 5, so that the second limit block 32 abuts against the side wall of the other end of the second limit opening 52, it means that the handle 5 is in an unlocked state and the column 3 can rotate. This setting is more intuitive, allowing the user to know the unlocking and locking positions of the handle 5, making the operation simpler and more convenient.

[0046] The first locking portion 31 is provided with a first locking groove 312 , and the locking block 511 is provided with a sliding block 512 ; when the handle 5 is rotated to make the sliding block 512 enter the first locking groove 312 , the column assembly is in a locked state.

[0047] like Figure 8 and 9 As shown, in this embodiment, the slider 512 is convexly arranged on the locking block 511. When the locking block 511 leaves the unlocking groove 311, until the slider 512 abuts against the first locking groove 312, it indicates that the locking position is reached. The slider 512 is arranged to cooperate with the first locking groove 312 to make the locking structure more stable. At the same time, the user can further determine that the locking is successful by the feel of the slider 512 being engaged in the first locking groove 312.

[0048] A second locking groove 313 is provided on the first locking portion 31, and the second locking groove 313 is adapted to the slider 512, and there is a height difference in the horizontal direction between the first locking groove 312 and the second locking groove 313; when the handle 5 is rotated to make the slider 512 enter the second locking groove 313, the column assembly is in a locked state.

[0049] like Figure 8 and 9 As shown, in this embodiment, the second locking groove 313 can further confirm whether the handle 5 is locked, making the structure more stable and reliable. The second locking groove 313 is higher than the first locking groove 312 in the horizontal direction. When the slider 512 is rotated and locked, it first passes through the first locking groove 312 and then enters the second locking groove 313. Setting such a height difference can improve the hand feel and make the user feel the vibration when locking more clearly.

[0050] The locking and unlocking assembly also includes a connecting rod 7, which passes through the handle 5, the column assembly and the fixing member 2 at the same time. One end of the connecting rod 7 is connected to the body 1, and the other end of the connecting rod 7 is abutted and connected to the handle 5.

[0051] like Figure 3 and 4 As shown, in this embodiment, a nut is provided at one end of the connecting rod 7 close to the handle 5, the connecting rod 7 is fixed, and the nut provides a limiting function for the handle 5. When the user rotates the handle 5 to make the locking block 511 leave the unlocking slot 311, the locking block 511 will apply a thrust to the column assembly, so that the column assembly moves in a direction close to the body assembly until the latch 41 is inserted into the socket 21 and locked. At this time, the spring 61 is compressed, and the handle 5 is limited by the nut and cannot move, so as to form a locked state. When the user rotates the handle 5 to make the locking block 511 rotate to a position corresponding to the unlocking slot 311, the column assembly moves in a direction close to the handle 5 under the action of the spring 61 until the locking block 511 is engaged with the unlocking slot 311 to form an unlocked state.

[0052] Another embodiment of the utility model provides a treadmill, comprising the above-mentioned column folding mechanism.

[0053] Although the disclosure is as above, the protection scope of the disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the disclosure, and these changes and modifications will fall within the protection scope of the utility model.
