Description

Technical Field

[0001] The utility model relates to the field of treadmills, and particularly relates to a treadmill capable of reducing the probability of the upright post toppling over. Background Art

[0002] A treadmill is a fitness equipment commonly used in families and gyms. Moreover, it is the simplest one among current home fitness equipment and is the best choice for home fitness equipment.

[0003] Chinese Patent with publication number CN216222762U discloses a folding treadmill, which includes a running platform, upright posts hinged on both sides of the running platform, and a locking structure arranged between the upright posts and the running platform to limit the relative rotation of the upright posts with respect to the running platform. The locking structure includes a rotating shaft rotatably arranged on the running platform and passing through the upright posts at both ends, fixed disks concentrically and fixedly arranged on both sides of the running platform with respect to the rotating shaft, a moving disk concentrically and fixedly arranged on the upright posts with respect to the rotating shaft, and a limiting component arranged between the fixed disk and the moving disk to limit the relative rotation of the moving disk with respect to the fixed disk. The activation or release of the limiting structure is controlled by the moving disk approaching or moving away from the fixed disk. A control mechanism for controlling the moving disk to approach or move away from the fixed disk synchronously is arranged between the rotating shaft and the upright posts. The limiting component includes a first tooth surface arranged on one side of the fixed disk close to the main body and a second tooth surface arranged on one side of the moving disk close to the running platform and meshing with or disengaging from the first tooth surface. The rotating shaft can rotate and slide relative to the running platform. The control mechanism includes a limiting block arranged at one end of the rotating shaft, a mounting block arranged at the other end of the rotating shaft, and a driving component arranged between the mounting block and the upright post close to the mounting block to increase or decrease the distance between the mounting block and this upright post. The driving component includes a fixed block arranged on the side of the upright post far from the running platform close to the mounting block, a convex block arranged on the side of the fixed block far from the upright post, a pressing block arranged on the side of the mounting block close to the fixed block and fitting with the convex block, and a guiding block arranged on the mounting block and fitting with the pressing block. The side surface of the guiding block close to the fixed block is arranged as an inclined surface whose distance from the mounting block gradually decreases along the circumferential direction of the rotating shaft from the side close to the mounting block to the side far from the mounting block. The maximum distance between this inclined surface and the mounting block is equal to the height of the pressing block. During the rotation of the mounting block, the convex block and this inclined surface are in extrusion and sliding cooperation.

[0004] When the mounting block on the rotating shaft rotates to make the inclined surface thereon abut against the convex block on the fixed block of the upright post, at this time, the second tooth surface arranged on the moving disk can be disengaged from the first tooth surface on the fixed disk, and at this time, the upright post can rotate. However, when people run on the running platform, vibrations will be generated, and the vibrations on the running platform will also act on the mounting block at the bottom of the upright post, causing the mounting block to deflect. If the mounting block deflects when people are running on the running platform, resulting in the inclined surface on the mounting block abutting against the convex block on the fixed block, at this time, the upright post will topple down due to gravity, thereby increasing the probability of danger when people exercise on the treadmill. Content of the Utility Model

[0005] In view of the disadvantages of the prior art that when people run on a treadmill, vibrations will be generated, and the vibrations on the treadmill will also act on the mounting blocks at the bottom of the columns, causing the mounting blocks to deflect. If people run on the treadmill and the mounting blocks deflect, the inclined surfaces on the mounting blocks will abut against the bumps on the fixed blocks. At this time, the columns will fall down due to gravity, resulting in an increased probability of danger when people exercise on the treadmill, the present utility model provides a treadmill that can reduce the probability of the columns falling down.

[0006] To solve the above technical problems, the present utility model is solved by the following technical solutions:

[0007] A treadmill that can reduce the probability of the columns falling down, comprising a running platform, columns rotatably arranged on both sides of the running platform through rotating shafts, and a locking component for restricting the relative rotation of the columns with respect to the running platform. The locking component includes a fixed gear disk fixed to the running platform and a movable gear disk that can approach or move away from the fixed gear disk, which are respectively arranged on the opposite sides of the running platform and the columns. The rotating shaft is rotatably inserted into the central holes of the fixed gear disk and the movable gear disk. A driving component that rotates synchronously in the positive and negative directions with the rotating shaft and can drive the movable gear disk to approach and engage with the fixed gear disk or move away from the fixed gear disk as it rotates in the positive and negative directions is fixed to one end of the rotating shaft away from the running platform. A damping component for increasing the rotational resistance of the rotating shaft is arranged between the rotating shaft and the movable gear disk. The damping component includes a pressing member elastically telescoped on the inner wall of the central hole of the movable gear disk and an abutting plane arranged on the outer wall of the rotating shaft for the pressing member to abut against.

[0008] With the above scheme, the pressing member elastically telescoped on the inner wall of the central hole of the movable gear disk can abut against the abutting plane on the rotating shaft when the columns are erected on both sides of the running platform. At this time, the damping of the rotation of the rotating shaft will increase, and the probability of the rotating shaft driving the driving component to rotate will decrease, reducing the probability of the mutually engaged fixed gear disk and movable gear disk separating from each other, thereby reducing the probability of the columns falling down due to the vibrations generated when people run on the treadmill.

[0009] Preferably, the pressing member includes a receiving hole arranged on the inner wall of the central hole of the movable gear disk, a ball telescoped on the receiving hole, and an elastic member for elastically pressing the ball against the abutting plane.

[0010] With the above scheme, the ball arranged can abut against the surface of the rotating shaft inserted into the central hole of the movable gear disk when it is installed in the receiving hole. When the ball abuts against the abutting plane on the rotating shaft, the ball will be pushed by the elastic member and partially protrude out of the receiving groove and abut against the abutting plane on the rotating shaft. At this time, the rotational damping of the rotating shaft will increase, thereby reducing the probability of the columns falling down due to the vibrations when people run on the treadmill.

[0011] Preferably, the receiving hole penetrates through the outer ring wall of the movable gear disk, and a pressing member for closing the receiving hole and pressing the elastic member and the ball is provided at one end of the receiving hole close to the outer ring wall of the movable gear disk.

[0012] Adopting the above solution, arranging the receiving hole to penetrate through the outer ring wall of the movable gear disk facilitates the installation of the ball and the pressing member into the receiving hole.

[0013] Preferably, the receiving hole is a threaded through hole, and the pressing member is a jacking bolt that mates with the threaded through hole.

[0014] Adopting the above solution, when the elastic member and the ball are installed into the receiving hole, the jacking bolt can close one end of the receiving hole close to the outer ring wall of the movable gear disk. At the same time, after the jacking bolt is screwed into the receiving hole, it can also squeeze the elastic member installed in the receiving hole, so that the elastic member is in a state where the ball is ejected to partially protrude out of the receiving hole after the ball retracts.

[0015] Preferably, a blocking member for restricting the ball from detaching from the receiving hole is provided at one end of the receiving hole close to the rotating shaft.

[0016] Preferably, the blocking member includes a blocking ring protruding from one end of the receiving hole close to the rotating shaft, and the ball partially penetrates through the blocking ring and is in abutting fit with the abutting plane.

[0017] Adopting the above solution, when the ball is loaded into the receiving hole, the provided blocking ring can block the ball, so that the ball can only partially protrude out of the blocking ring and abut against the splicing plane on the rotating shaft, thus facilitating the installation of the ball.

[0018] Preferably, one end of the rotating shaft away from the driving member is a threaded section. The threaded section passes through the fixed gear disk and is threadedly fitted with a locking nut. An anti-detachment member for restricting the relative rotation of the locking nut with respect to the threaded section is provided on the locking nut.

[0019] Adopting the above solution, by screwing the locking nut onto the threaded section at one end of the rotating shaft away from the driving member, the probability of the rotating shaft detaching from the fixed gear disk and the movable gear disk can be reduced. The anti-detachment member provided on the locking nut can reduce the probability of the locking nut detaching from the threaded section of the rotating shaft, thereby further reducing the probability of the rotating shaft detaching from the fixed gear disk and the movable gear disk.

[0020] Preferably, the anti-detachment member includes a threaded hole vertically opened on the outer wall of the locking nut and a pressing bolt that mates with the threaded hole and abuts against the threaded section.

[0021] Adopting the above solution, after the locking nut is screwed onto the threaded section of the rotating shaft, the provided pressing bolt can be screwed into the threaded hole on the locking nut, thereby pressing the threaded section of the rotating shaft and reducing the probability of the locking nut rotating relative to the threaded section.

[0022] Preferably, the driving component includes a driving handle located at one end of the movable gear disk away from the fixed gear disk and fixedly connected to the rotating shaft, a pressing inclined surface and a pressing block which are respectively arranged on opposite sides of the driving handle and the movable gear disk and are in a state of abutting against each other, and a pressing plane which abuts against the pressing block after the movable gear disk and the fixed gear disk are engaged.

[0023] With the above scheme, when the driving handle rotates until the pressing inclined surface thereon abuts against the pressing block on the movable gear disk, the mortgaged block can slide on the mortgaged inclined surface at this time, and the movable gear disk can be disengaged from the fixed gear disk, and at this time the column can rotate; when the driving handle rotates until the pressing plane thereon abuts against the pressing block on the movable gear disk, the pressing block will abut against the pressing inclined surface at this time, and at this time the movable gear disk will be engaged with the fixed gear disk, and at this time the column is limited and cannot rotate.

[0024] Preferably, the elastic member is a spring.

[0025] With the above scheme, the arranged spring can drive the ball to partially extend out of the accommodating hole and abut against the abutting plane of the rotating shaft when the splicing plane balls on the rotating shaft are opposite.

[0026] Since the utility model adopts the above technical scheme, it has remarkable technical effects: when the column stands on both sides of the treadmill, the pressing member telescopically arranged on the inner wall of the central hole of the movable gear disk can abut against the abutting plane on the rotating shaft. At this time, the damping of the rotation of the rotating shaft will become larger, and the probability of the rotating shaft driving the driving component to rotate will be reduced, so that the probability of the mutually engaged fixed gear disk and movable gear disk being separated from each other will be reduced, thereby reducing the probability of the column tipping over due to the vibration generated when people run on the treadmill.

[0040] Embodiment

[0041] A treadmill capable of reducing the probability of the upright column tipping over, referring to Figures 1-4 , includes a running platform 1, upright columns 2 rotatably arranged on both sides of the running platform 1 through a rotating shaft 5, and a locking component for restricting the relative rotation of the upright columns 2 with respect to the running platform 1. The locking component includes a fixed gear disk 4 fixed to the running platform 1 and a moving gear disk 3 that can approach or move away from the fixed gear disk 4, which are respectively arranged on one side of the running platform 1 and the upright column 2 opposite to each other. The rotating shaft 5 is rotatably inserted into the central holes 6 of the fixed gear disk 4 and the moving gear disk 3. A driving component that rotates in the same direction and reversely as the rotating shaft 5 and can drive the moving gear disk 3 to approach and engage with the fixed gear disk 4 or move away from the fixed gear disk 4 as it rotates in the same direction and reversely is fixed to one end of the rotating shaft 5 away from the running platform 1. Referring to Figure 4 , Figure 11, the driving component includes a driving handle 18 located at one end of the movable gear disk 3 away from the fixed gear disk 4 and fixedly connected to the rotating shaft 5, and a pressing inclined surface 16 and a pressing block 19 which are arranged on opposite sides of the driving handle 18 and the movable gear disk 3 and are in a state of abutting against each other. One end of the pressing inclined surface 16 is provided with a pressing plane 17 which abuts against the pressing block 19 after the movable gear disk 3 and the fixed gear disk 4 are engaged. A damping component for increasing the rotational resistance of the rotating shaft 5 is arranged between the rotating shaft 5 and the movable gear disk 3. The damping component includes a pressing member elastically and telescopically arranged on the inner wall of the central hole 6 of the movable gear disk 3 and a abutting plane 15 arranged on the outer wall of the rotating shaft 5 for the pressing member to abut against.

[0042] Reference Figures 6-10 , the pressing member includes a receiving hole 8 arranged on the inner wall of the central hole 6 of the movable gear disk 3, a ball 7 telescopically arranged on the receiving hole 8, and an elastic member for elastically pressing the ball 7 against the abutting plane 15. The elastic member is a spring 9. The receiving hole 8 penetrates through the outer ring wall of the movable gear disk 3, and one end of the receiving hole 8 close to the outer ring wall of the movable gear disk 3 is provided with a pressing member for closing the receiving hole 8 and pressing the elastic member and the ball 7. The receiving hole 8 is a threaded through hole, and the pressing member is a jacking bolt 10 matched with the threaded through hole. One end of the receiving hole 8 close to the rotating shaft 5 is provided with a blocking component for restricting the ball 7 from disengaging from the receiving hole 8. The blocking component includes a blocking ring 11 protruding from one end of the receiving hole 8 close to the rotating shaft 5. The ball 7 partially penetrates through the blocking ring 11 and abuts against the abutting plane 15 in a matching manner.

[0043] Reference Figures 4-5 , one end of the rotating shaft 5 away from the driving component is a threaded section 14. The threaded section 14 passes through the fixed gear disk 4 and is threadedly matched with a locking nut 12. The locking nut 12 is provided with an anti-loosening component for restricting the locking nut 12 from rotating relative to the threaded section 14. The anti-loosening component includes a threaded hole 20 vertically opened on the outer wall of the locking nut 12 and a pressing bolt 13 matched with the threaded hole 20 and abutting against the threaded section 14.

[0044] Specific usage process of the vertical column: When the vertical column 2 needs to rotate, first, rotate the driving handle 18, so that the driving handle 18 drives the rotating shaft 5 to rotate. When the driving handle 18 rotates, the pressing block 19 on the moving gear disk 3 will gradually move from the pressing plane 17 on the driving handle 18 to the pressing inclined plane 16. When the pressing block 19 abuts against the pressing inclined plane 16, at this time, the moving gear disk 3 can be separated from the fixed gear disk 4, and the vertical column 2 can rotate relative to the running platform 1 and stand upright on both sides of the running platform 1. At the same time, the rotating shaft 5 will also squeeze the balls 7 in the moving gear disk 3, so that part of them retracts into the accommodating hole 8. At this time, the balls 7 will squeeze the spring 9 to make the spring 9 contract. When the vertical column 2 rotates and stands upright on both sides of the running platform 1, at this time, the driving handle 18 can be rotated again until the pressing plane 17 on it abuts against the pressing block 19 on the moving gear disk 3. At this time, the moving gear disk 3 will approach the fixed gear disk 4 and mesh with the fixed gear disk 4. At the same time, the rotating shaft 5 will also rotate under the drive of the driving handle 18 until the abutting plane 15 on it is opposite to the balls 7. At this time, the contracted spring 9 will recover and pop out part of the balls 7 outside the accommodating hole 8 and abut against the splicing plane, thereby increasing the damping of the rotation of the rotating shaft 5. At this time, the position of the vertical column 2 will be limited, and the probability that the vertical column 2 will fall due to the vibration generated by people on the running platform 1 will be reduced.

[0045] The above is only the preferred implementation mode of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
