[0045] The present disclosure provides a foldable treadmill for users to perform running exercises, and the foldable treadmill includes a frame and a support column. The support column is arranged on the frame and is used to install an armrest, and can also be used to install a display device, an operation panel and other devices required for the foldable treadmill, so that the user can obtain relevant motion information and adjust various parameters of the foldable treadmill when running or walking on the foldable treadmill.

[0046] Specifically, the support column is rotatably arranged on the frame, and is constructed to be able to rotate between a use position and a storage position relative to the frame, and can be fixed in the use position or the storage position by a clamping mechanism; the clamping mechanism includes a first clamping member, a second clamping member and a clamping elastic member, the first clamping member is arranged on the frame, the second clamping member is arranged on the support column, and the clamping elastic member is constructed to extend under the action of its own elastic force to push the second clamping member to clamp with the first clamping member, or to be compressed under the action of an external force to disengage the second clamping member from the first clamping member.

[0047] When the foldable treadmill of the present invention is in use, the compression elastic member of the clamping mechanism can extend under the action of its own elastic force to push the second clamping member to clamp with the first clamping member, so that the support column and the frame remain relatively fixed, so that the support column can be in a use position relative to the frame, and the display device, operation panel and other devices fixed on the support column can be located in front of the user, so that the user can obtain relevant motion information and adjust various parameters of the foldable treadmill when running or walking on the foldable treadmill.

Moreover, after the foldable treadmill of the present invention is folded, the thickness of the entire package is relatively small, which is conducive to the simultaneous transportation of a large number of foldable treadmills of the present invention.

[0049] When the foldable treadmill of the present invention needs to be converted to a motion state, since the support column and the frame can rotate relative to each other, the operator can directly push the support column to the use position, and then the compression elastic member of the clamping mechanism can extend under its own elastic force to push the second clamping member to clamp with the first clamping member, so that the support column and the frame remain relatively fixed, so as to fix the support column in the use position. The clamping mechanism in the foldable treadmill of the present invention can effectively switch the clamping state between the support column and the frame, the overall structure is simple, the operation is convenient and fast, and the user experience is effectively improved.

[0050] For ease of understanding, refer to Figures 1 to 12 , the specific structure and working principle of the foldable treadmill disclosed in the present invention are explained in detail in combination with an embodiment.

[0051] like Figures 1 to 10 As shown, the present disclosure provides a foldable treadmill for users to perform running exercises, and includes a frame 10 and a support column 20. The support column 20 is arranged on the frame 10, and is used to install an armrest 40. It can also be used to install a display device, an operation panel and other devices required for the foldable treadmill, so that the user can obtain relevant motion information and adjust various parameters of the foldable treadmill when running or walking on the foldable treadmill.

[0052] Specifically, Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 and Fig. 9 As shown, the support column 20 is rotatably arranged on the frame 10, and is constructed to be able to rotate between the use position and the storage position relative to the frame 10, and can be fixed in the use position or the storage position by a clamping mechanism 30; the clamping mechanism 30 includes a first clamping member 31, a second clamping member 32 and a clamping elastic member 33, the first clamping member 31 is arranged on the frame 10, the second clamping member 32 is arranged on the support column 20, and the clamping elastic member 33 is constructed to extend under the action of its own elastic force to push the second clamping member 32 to clamp with the first clamping member 31, or to be compressed under the action of an external force to disengage the second clamping member 32 from the first clamping member 31.

[0053] like Figures 3 to 5 As shown, when the foldable treadmill of the present invention is in use, the compression elastic member 33 of the clamping mechanism 30 can be extended under the action of its own elastic force to push the second clamping member 32 to clamp with the first clamping member 31, so that the support column 20 and the frame 10 remain relatively fixed, so that the support column 20 can be in a use position relative to the frame 10, and the display device, operation panel and other devices fixed on the support column 20 can be located in front of the user, so that the user can obtain relevant motion information and adjust various parameters of the foldable treadmill when running or walking on the foldable treadmill.

[0054] And as Figures 7 to 9 As shown, when the foldable treadmill of the present invention needs to be stored or transported, the user or other operator can compress the clamping elastic member 33 of the clamping mechanism 30 through external force to disengage the second clamping member 32 from the first clamping member 31, so that the support column 20 and the frame 10 can rotate relative to each other. The operator can then rotate the support column 20 to the storage position, thereby folding the foldable treadmill of the present invention, effectively reducing the space occupied by the foldable treadmill of the present invention, which is not only convenient for the storage of the foldable treadmill of the present invention, but also for its packing. Moreover, after the foldable treadmill of the present invention is folded, the thickness of the entire package is relatively small, which is conducive to the simultaneous transportation of a large number of foldable treadmills of the present invention.

[0055] When the foldable treadmill of the present disclosure needs to be converted to a motion state, since the support column 20 and the frame 10 can rotate relative to each other, the operator can directly push the support column 20 to the use position, and then the compression elastic member 33 of the clamping mechanism 30 can extend under its own elastic force to push the second clamping member 32 to clamp with the first clamping member 31, so that the support column 20 and the frame 10 remain relatively fixed, so as to fix the support column 20 in the use position. The clamping mechanism 30 in the foldable treadmill of the present disclosure can effectively switch the clamping state between the support column 20 and the frame 11, the overall structure is simple, the operation is convenient and quick, and the user experience is effectively improved.

[0056] like Figure 3As shown, in one embodiment of the present disclosure, the support column 20 is configured to have an angle with the frame 10 when in the use position, and to be parallel to the frame 10 when in the storage position. When the support column 20 is in the use position, the display device, operation panel and other devices fixed on the support column 20 can be at a certain height from the frame 10, which is convenient for the user to obtain relevant motion information and adjust various parameters of the foldable treadmill when running or walking on the foldable treadmill; and when the support column 20 is configured to be parallel to the frame 10 when in the storage position, the overall thickness of the foldable treadmill of the present disclosure can be effectively reduced after the folding of the foldable treadmill of the present disclosure, which is not only convenient for the storage of the foldable treadmill of the present disclosure, but also convenient for its packaging. After packaging, the thickness of the entire package is small, which is conducive to the simultaneous transportation of a large number of foldable treadmills of the present disclosure.

[0057] Specifically, Figure 3 As shown, the angle between the support column 20 and the frame 10 when in the use position can be an acute angle between 60° and 75°, so that the display device, operation panel and other devices fixed on the support column 20 can be located in a more suitable position in front of the user. In other embodiments of the present disclosure, the angle between the support column 20 and the frame 10 when in the use position can be set as needed, which is not limited here.

[0058] In order to ensure that the support column 20 is parallel to the frame 10 when in the storage position. Figure 5 As shown, in one embodiment of the present disclosure, the frame 10 includes a frame body 11 and a fixing portion 12, the fixing portion 12 is configured to protrude from the upper surface of the frame body 11 and is located at the front end of the frame body 11, the fixing shaft 13 is fixedly disposed on the fixing portion 12, and the support column 20 is configured to be rotatably disposed on the fixing shaft 13 extending in the horizontal direction on the frame 10, the support column 20 is always located above the frame 10 during the process of rotating around the fixing shaft 13, and can be rotated to be parallel to the frame 10 without interfering with the frame 10. After the foldable treadmill of the present disclosure is folded, the overall thickness is approximately the sum of the thickness of the support column 20 and the thickness of the frame 10, which can effectively reduce the overall thickness of the foldable treadmill of the present disclosure after folding.

[0059] In another embodiment of the present disclosure, the frame 10 includes a frame body 11 and a fixing portion 12, the fixing portion 12 is constructed to be located on the front side of the frame body 11 and at the same height as the frame body 11, the fixing shaft 13 is fixedly arranged on the fixing portion 12, and the support column 20 is constructed to be rotatably arranged on the fixing shaft 13 extending in the horizontal direction on the frame 10, and is located on the outside of the frame 10 in the vertical plane; the support column 20 can rotate to the same horizontal height as the frame 10 during the rotation around the fixing shaft 13, and will not interfere with the frame 10. After the foldable treadmill of the present disclosure is folded, the overall thickness is approximately the larger thickness of the support column 20 and the thickness of the frame 10, usually the thickness of the frame 10, thereby further reducing the overall thickness of the foldable treadmill of the present disclosure after folding.

[0060] The structure of the clamping mechanism 30 can be various, such as Figure 5 As shown, in one embodiment of the present disclosure, the first clamping member 31 is configured to be fixedly disposed on the fixed shaft 13 and is generally circular; the second clamping member 32 is disposed on the support column 20 and is generally arc-shaped and disposed on the circumferential outer side of the first clamping member 31. The second clamping member 32 can move around the circumferential outer side of the first clamping member 31 during the rotation of the support column 20 around the fixed shaft 13, and can approach the first clamping member 31 under the action of the compression elastic member 33 and be clamped at different circumferential positions of the first clamping member 31, so that the support column 20 can rotate between the use position or the storage position and be fixed in the use position or the storage position.

[0061] Further, such as Figure 5 and Fig. 9 As shown, in one embodiment of the present disclosure, a first latching member 31 is provided with a first latching tooth portion 311, and a second latching member 32 is provided with a second latching tooth portion 321, and the first latching tooth portion 311 and the second latching tooth portion 321 are configured to be able to engage at a first extreme position and a second extreme position, so that the support column 20 can be fixed in the use position or the storage position by the latching mechanism 30. The first latching member 31 and the second latching member 32 are engaged by the first latching tooth portion 311 and the second latching tooth portion 321 that can engage with each other, so that the first latching tooth portion 311 and the second latching tooth portion 321 can engage at the first extreme position and the second extreme position, so that the support column 20 can be fixed in the use position or the storage position by the latching mechanism 30.

[0062] Specifically, the length of the tooth section of the first tooth portion 311 is greater than the length of the second tooth portion 321; when the second tooth portion 321 is fully engaged with the first end of the first tooth portion 311, the first tooth portion 311 and the second tooth portion 321 are engaged at the first extreme position, and at this time, the support column 20 is in the use position; when the second tooth portion 321 is fully engaged with the second end of the first tooth portion 311, the first tooth portion 311 and the second tooth portion 321 are engaged at the second extreme position, and at this time, the support column 20 is in the storage position.

[0063] Specifically, Figure 1 As shown, in one embodiment of the present disclosure, the support column 20 is rotatably arranged between the fixed portion 12 and the first clamping member 31, which can effectively ensure that the support column 20 will not deflect during the rotation around the fixed axis 13, and the support column 20 is close to the first clamping member 31, so that the second clamping member 32 on the support column 20 can be clamped with the first clamping member 31.

[0064] Further, such as Figure 5 and Fig. 9 As shown, in one embodiment of the present disclosure, the first latching tooth portion 311 and the second latching tooth portion 321 are configured to be able to engage at any position between the first extreme position and the second extreme position, so that the support column 20 can be fixed at any position between the use position and the storage position through the latching mechanism 30. Figure 5 As shown, when the first latch tooth portion 311 is engaged between the first end and the second end of the second latch tooth portion 321, the first latch tooth portion 311 and the second latch tooth portion 321 are engaged at any position between the first extreme position and the second extreme position, and the angle between the support column 20 and the bracket can be adjusted to better adapt to users of different heights.

[0065] Specifically, Figure 5 and Fig. 9 As shown, in one embodiment of the present disclosure, a first tooth portion 311 is provided on the outer peripheral surface of the first clamping member 31; the second clamping member 32 is provided with a rotating end 322 and a free end 323, the rotating end 322 is rotatably provided on the support column 20, the free end 323 is constructed to be rotated under control of an external force, and the second clamping member 32 is provided with a second tooth portion 321 on the inner peripheral surface between the rotating end 322 and the free end 323; the second tooth portion 321 is constructed to engage with or disengage from the first tooth portion 311 during the rotation of the second clamping member 32.

[0066] When the second clamping member 32 needs to be separated from the first clamping member 31, it is only necessary to control the free end 323 of the second clamping member 32 to rotate under the control of external force, so that the second tooth portion 321 can be separated from the first tooth portion 311, that is, the second clamping member 32 is separated from the first clamping member 31; when the second clamping member 32 needs to be clamped with the first clamping member 31, the clamping elastic member 33 of the clamping mechanism 30 can extend under the action of its own elastic force to push the free end 323 of the second clamping member 32 to rotate, thereby making the second tooth portion 321 mesh with the first tooth portion 311, that is, the second clamping member 32 is clamped with the first clamping member 31. When it is necessary to adjust the clamping angle between the support column 20 and the frame 10, it is only necessary to control the second clamping piece 32 to separate from the first clamping piece 31, and then rotate the support column 20. During the rotation of the support column 20, the second clamping piece 32 will be driven to rotate. After the support column 20 is rotated to the target position, the second clamping piece 32 is controlled to clamp with the first clamping piece 31. The second clamping piece 32 can move around the circumferential outer side of the first clamping piece 31 during the rotation of the support column 20 around the fixed axis 13, and be clamped at different circumferential positions of the first clamping piece 31, so that the support column 20 can rotate between the use position or the storage position, and be fixed in the use position, the storage position, or any position of the use position and the storage position.

[0067] like Figure 5 and Fig. 9 As shown, in one embodiment of the present disclosure, the first latch tooth portion 311 and the second latch tooth portion 321 are both helical teeth, the helical teeth of the first latch tooth portion 311 are configured to be inclined toward the rotating end 322 , and the helical teeth of the second latch tooth portion 321 are configured to be inclined toward the free end 323 . Since the first latch tooth portion 311 and the second latch tooth portion 321 are both bevel teeth, and the bevel teeth of the first latch tooth portion 311 are inclined toward the rotating end 322 side, and the bevel teeth of the second latch tooth portion 321 are inclined toward the free end 323 side, the first latch tooth portion 311 and the second latch tooth portion 321 can be staggered at an angle, which helps to improve the clamping strength between the first latch tooth portion 311 and the second latch tooth portion 321. When the first latch tooth portion 311 and the second latch tooth portion 321 are in the clamping state, even if the user shakes the support column 20, the first latch tooth portion 311 and the second latch tooth portion 321 are not easy to separate, thereby ensuring that when the user shakes the support column 20 in the use position, the support column 20 can remain in the use position and will not suddenly rotate and slide, thereby ensuring the safety of the user when using the foldable treadmill disclosed herein.

[0068] Further, such as Figure 5 and Fig. 9As shown, in one embodiment of the present disclosure, a first limiting assembly 81 is provided between the support column 20 and the frame 10, and the first limiting assembly 81 is configured to limit the rotation of the support column 20 between the use position and the storage position. By providing the first limiting assembly 81 on the support column 20 and the frame 10, the rotation range of the support column 20 can be effectively limited, and the user is prevented from excessively rotating the support column 20, which causes the support column 20 to be unable to be fixed. Specifically, the first limiting assembly 81 may include a first limiting column 811 provided on one of the support column 20 and the frame 10 and a first limiting groove 812 provided on the other. During the rotation of the support column 20 on the frame 10, the first limiting column 811 can rotate relative to the first limiting groove 812 in the first limiting groove 812. When the first limiting column 811 moves to the two ends of the first limiting groove 812, it will be blocked, thereby preventing the support column 20 from continuing to rotate.

[0069] like Figures 1 to 10 As shown, in one embodiment of the present disclosure, the foldable treadmill of the present disclosure also includes an armrest portion 40. When the user runs or walks on the foldable treadmill, the user can hold the armrest portion 40. The armrest portion 40 helps the user maintain balance, which can effectively reduce the risk of falling and injury. It can also provide support for the user's body, reduce foot pressure when tired, extend the exercise time and achieve better results.

[0070] like Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the armrest portion 40 is rotatably arranged on the frame 10, and is constructed to be rotatable between a first position and a second position relative to the support column 20, and a transmission member 50 is provided on the armrest portion 40 that is transmission-connected to the clamping mechanism 30. The transmission member 50 is constructed to drive the clamping mechanism 30 to keep the support column 20 and the frame 10 relatively fixed when the armrest portion 40 is rotated to the first position, and to drive the clamping mechanism 30 to enable the support column 20 and the frame 10 to rotate relative to each other when the armrest portion 40 is rotated to the second position.

[0071] like Figure 3 and Figure 4 As shown, when the foldable treadmill of the present invention is in use, the armrest portion 40 is in the first position, and the armrest portion 40 can drive the clamping mechanism 30 through the transmission member 50 to keep the support column 20 relatively fixed to the frame 10, so that the support column 20 can be in the use position relative to the frame 10, and the display device, operation panel and other devices fixed on the support column 20 can be located in front of the user, so that the user can obtain relevant motion information and adjust various parameters of the foldable treadmill when running or walking on the foldable treadmill.

[0072] like Figure 7 and Figure 8 As shown, when the foldable treadmill of the present invention needs to be stored or transported, the user or other operator can control the armrest portion 40 to rotate to the second position. When the armrest portion 40 is rotated to the second position, the transmission member 50 can be used to drive the clamping mechanism 30 to allow the support column 20 and the frame 10 to rotate relative to each other. The operator can then rotate the support column 20 to the storage position, thereby folding the foldable treadmill of the present invention, effectively reducing the space occupied by the foldable treadmill of the present invention, which is not only convenient for the storage of the foldable treadmill of the present invention, but also for its packing. Moreover, after the foldable treadmill of the present invention is folded, the thickness of the entire package is relatively small, which is conducive to the simultaneous transportation of a large number of foldable treadmills of the present invention.

[0073] When the foldable treadmill of the present disclosure needs to be converted to a motion state, since the armrest 40 is already in the second position, the support column 20 and the frame 10 can rotate relative to each other, and the operator can directly push the support column 20 to the use position, and then push the armrest 40 to rotate to the first position, so as to use the transmission member 50 to drive the clamping mechanism 30 to keep the support column 20 and the frame 10 relatively fixed, so as to fix the support column 20 in the use position. Whether it is a folding process or an unfolding process, the user can use the rotating armrest 40 to switch the clamping state between the support column 20 and the frame 11, which is convenient and quick to operate, and effectively improves the user's experience.

[0074] Specifically, Figures 3 to 10 As shown, in one embodiment of the present disclosure, the first end of the transmission member 50 is arranged on the armrest portion 40, and the second end is constructed to be transmission-connected to the first clamping member 31, and is constructed to pull the second clamping member 32 to rotate during the rotation of the armrest portion 40 to the second position, so as to disengage the second clamping member 32 from the first clamping member 31 and compress the elastic member 33.

[0075] During the rotation of the armrest portion 40 from the first position to the second position, the free end 323 of the second clamping member 32 can be pulled to rotate through the transmission member 50, compressing the clamping elastic member 33, and causing the second clamping member 32 to disengage from the first clamping member 31. During the rotation of the armrest portion 40 from the second position to the first position, the clamping elastic member 33 can extend under the action of its own elastic force to push the free end 323 of the second clamping member 32 to rotate, thereby pushing the second clamping member 32 to clamp with the first clamping member 31, thereby keeping the support column 20 and the frame 10 relatively fixed.

[0076] like Figure 1 and Figure 2As shown, in one embodiment of the present disclosure, in the foldable treadmill of the present disclosure, two support columns 20 are provided and are located on the left and right sides of the frame 10, and two armrests 40 are provided and are respectively provided on the corresponding support columns 20. When the user runs or walks on the foldable treadmill, the user can hold the armrests 40 on both sides with both hands to maintain body balance and reduce the risk of falling and injury. The two armrests 40 can also provide support for the user's body at the same time, reduce the pressure on the feet when tired, further extend the user's exercise time and achieve better results.

[0077] like Figure 1 and Figure 2 As shown, the foldable treadmill of the present invention also includes a running belt 60 and a crossbeam portion 70. The running belt 60 is arranged on the frame 10 and is located between two support columns 20 and / or between two armrest portions 40. The running belt 60 is constructed to rotate under the action of external force, and the crossbeam portion 70 is fixedly arranged inside the upper ends of the two support columns 20.

[0078] Specifically, the treadbelt 60 can rotate driven by the motor, and the user can run or walk on the treadbelt 60. The crossbeam 70 is used for display devices, operation panels and other devices. When the support column 20 is in the use position relative to the frame 10, the display device, operation panel and other devices can be located in front of the user, so that the user can obtain relevant motion information when running or walking on the foldable treadmill and adjust various parameters of the foldable treadmill, such as the working state of the treadbelt 60, the rotation speed and the like.

[0079] like Figure 3 and Figure 4 As shown, in one embodiment of the present disclosure, the armrest portion 40 is configured to have an angle with the support column 20 when in the first position, and to be parallel to the support column 20 when in the second position. Since the armrest portion 40 has an angle with the support column 20 when in the first position, it is convenient for the user to hold the armrest portions 40 on both sides; since the armrest portion 40 is parallel to the support column 20 when in the second position, the overall thickness of the foldable treadmill of the present disclosure after folding can be further reduced. Further, as Figure 3 and Figure 4 As shown, the armrest 40 is in the first position, and the support column 20 is parallel to the frame 10 when in the use position, which makes it easier for the user to hold the armrests 40 on both sides, making the user more comfortable when using the foldable treadmill of the present disclosure.

[0080] like Figure 6 and Fig.10As shown, in one embodiment of the present disclosure, a winding shaft 41 is provided on the armrest portion 40, and the first end of the transmission member 50 is fixed on the winding shaft 41, and is constructed to be tightened on the winding shaft 41 during rotation along the first direction, so as to use the second end to pull the second clamping member 32 to rotate, and to be released on the winding shaft 41 during rotation along the second direction, so that the clamping elastic member 33 pushes the first clamping member 31 to clamp with the second clamping member 32.

[0081] It is understandable that if Figure 3 and Figure 4 As shown, in one embodiment of the present disclosure, the first direction is a direction closer to the second position from the first position, and the second direction is a direction closer to the first position from the second position. Figures 8 to 10 As shown, during the rotation of the armrest 40 from the first position to the second position along the first direction, the transmission member 50 is gradually tightened on the winding shaft 41, and the second end of the transmission member 50 pulls the free end 323 of the second clamping member 32 to rotate, compresses the clamping elastic member 33, and causes the second clamping member 32 to be separated from the first clamping member 31. During the rotation of the armrest 40 from the second position to the first position along the second direction, the clamping elastic member 33 can extend under its own elastic force to push the free end 323 of the second clamping member 32 to rotate, so that the transmission member 50 is gradually released on the winding shaft 41, and the second clamping member 32 is pushed to clamp with the first clamping member 31, so that the support column 20 and the frame 10 remain relatively fixed.

[0082] Further, such as Figures 3 to 10 As shown, in one embodiment of the present disclosure, a guide portion 21 is fixedly provided at the upper end of the support column 20, and an abutment portion 22 is fixedly provided at the lower end, and the transmission member 50 is configured to penetrate the guide portion 21 and the abutment portion 22. The guide portion 21 and the abutment portion 22 can effectively limit the movement range of the transmission member 50, prevent external interference, and play a role in protecting the transmission member 50.

[0083] like Figures 3 to 10 As shown, in one embodiment of the present disclosure, the clamping elastic member 33 is configured to have one end abutting against the abutting portion 22, and the other end abutting against the second clamping member 32. Specifically, one end of the clamping elastic member 33 abuts against the abutting portion 22, and the other end abuts against the free end 323 of the second clamping member 32, so that the clamping elastic member 33 can effectively extend under the action of its own elastic force to push the second clamping member 32 to clamp with the first clamping member 31.

[0084] like Figure 6 and Fig.10As shown, in one embodiment of the present disclosure, a winding portion 23 is provided in the support column 20, and the winding portion 23 is located above the armrest portion 40; the transmission member 50 is configured to extend from above the guide portion 21, bypass the winding portion 23, and then be fixed on the winding shaft 41 of the armrest portion 40. Since the transmission member 50 extends from above the guide portion 21, bypasses the winding portion 23, and is then fixed on the winding shaft 41 of the armrest portion 40, the contact surface between the transmission member 50 and the winding portion 23 is a smooth curved surface, which can effectively reduce the friction generated during the reciprocating movement of the transmission member 50, and effectively extend the service life of the transmission member 50.

[0085] Therefore, in one embodiment of the present disclosure, the foldable treadmill of the present disclosure also includes a fixing member, which is configured to fix the armrest portion 40 in a first position so that the clamping mechanism 30 can keep the support column 20 relatively fixed to the frame 10, or to fix the armrest portion 40 in a second position so that the support column 20 can remain in a state of relative rotation with the frame 10.

[0086] When the fixing piece fixes the armrest portion 40 in the first position, it can ensure that the armrest portion 40 will not rotate when the user holds the armrest portion 40, thereby preventing the user from pushing the armrest portion 40 empty. It can also effectively prevent the user from mistakenly pushing the armrest portion 40 to the second position, causing the support column 20 to rotate relative to the frame 10, causing various structures such as the support column 20 and the armrest portion 40 to suddenly fall off, thereby ensuring the user's safety.

[0087] When the fixing member fixes the armrest portion 40 in the second position, it can prevent the compression elastic member 33 from being able to pull the armrest portion 40 from the second position to the first position through the transmission member 50 under the action of its own elastic force, and facilitate the armrest portion 40 to remain in the second position, parallel to the support column 20, so as to further reduce the overall thickness of the foldable treadmill of the present invention after folding.

[0088] Specifically, Fig.11 and Fig.12As shown, in one embodiment of the present disclosure, a column fixing hole 91 is provided on the support column 20, and a first handrail fixing hole 92 and a second handrail fixing hole 93 are provided on the handrail portion 40. The fixing piece is constructed to penetrate the column fixing hole 91 and one of the first handrail fixing hole 92 and the second handrail fixing hole 93 to fix the handrail portion 40 in the first position or the second position. That is, when the handrail portion 40 is in the first position, the first handrail fixing hole 92 overlaps with the column fixing hole 91, and the user can pass the fixing piece through the column fixing hole 91 and the first handrail fixing hole 92 to fix the handrail portion 40 in the first position; when the handrail portion 40 is in the second position, the second handrail fixing hole 93 overlaps with the column fixing hole 91, and the user can pass the fixing piece through the column fixing hole 91 and the second handrail fixing hole 93 to fix the handrail portion 40 in the second position. The foldable treadmill disclosed in the present disclosure can also use other devices to fix the handrail portion 40 in the first position or the second position, which will not be repeated here.

[0089] Further, such as Fig.11 and Fig.12 As shown, in one embodiment of the present disclosure, a second limiting assembly 82 is provided between the armrest portion 40 and the support column 20, and the second limiting assembly 82 is configured to limit the rotation of the armrest portion 40 between the use position and the storage position. By providing the second limiting assembly 82 on the armrest portion 40 and the support column 20, the rotation range of the armrest portion 40 can be effectively limited to prevent the user from over-rotating the armrest portion 40. Specifically, the second limiting assembly 82 may include a second limiting column 821 provided on one of the armrest portion 40 and the support column 20 and a second limiting groove 822 provided on the other. During the rotation of the armrest portion 40 on the support column 20, the second limiting column 821 can rotate relative to the second limiting groove 822 in the second limiting groove 822. When the second limiting column 821 moves to the two ends of the second limiting groove 822, it will be blocked, thereby preventing the armrest portion 40 from continuing to rotate.
