Description

Technical Field

[0001] This utility model belongs to the field of treadmills, and in particular relates to a quick disassembly and fixing device for treadmill uprights. Background Technology

[0002] Treadmills or walking machines are common fitness equipment in people's daily lives. They are devices used for walking or running exercises. To increase exercise intensity, people often find that the speed of a walking machine without handrails is limited to within 6 km / h. Adding handrails allows for a higher speed limit and increased exercise intensity. However, some machines on the market have a structure with a central support column and handrails, which is complex and difficult to assemble. They are usually transported fully assembled, resulting in a larger package size, which is inconvenient for transport.

[0003] For example, a Chinese invention patent discloses a safe and comfortable treadmill [application number CN201810690079.3], which includes a treadmill body, a running platform, and a support column. The support column is movably connected to the rear of the treadmill body, and a fixed platform is fixedly connected to the top of the support column. A handrail is nested at the top of the front of the support column, and a protective pad is nested around the outside of the handrail. A mounting plate is fixedly connected to the front of the treadmill body, and the running platform is nested in the middle of the mounting plate. Rollers are movably connected to the lower part of the retraction cavity. The rollers can rotate, making it easier and less strenuous to move the treadmill body. The ventilation holes can blow out cool air, improving the comfort of using the treadmill body. However, this structure is complex, difficult to assemble, and has high manufacturing costs. Usually, it is transported in its assembled state, but the package is large and not conducive to transportation. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by providing a quick disassembly and fixing device for treadmill uprights.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A quick-release and fixing device for a treadmill upright includes a frame base, with support frames on both sides of the frame base. Handrails are connected to the support frames, and anti-rotation components are provided on the outer side of the handrails. When the handrails and anti-rotation components are in contact, they form a snap-fit. The anti-rotation components have through holes that penetrate the support frames. A screw is inserted through the handrail, and the screw passes through the through hole with a nut screwed to the end of the screw away from the handrail, which is in contact with the inner side of the support frame.

[0006] In the aforementioned quick disassembly and fixing device for a treadmill column, the handrail is provided with a locking and releasing arc channel, and both ends of the locking and releasing arc channel are provided with end walls. A connecting block is fixed on the screw. When the connecting block abuts against one end of the locking and releasing arc channel, the handrail and the anti-rotation component are in a fitted state. When the connecting block abuts against the other end of the locking and releasing arc channel, the handrail and the anti-rotation component are in a non-fitted state.

[0007] In the aforementioned treadmill column quick disassembly and fixing device, the handrail has a circular cavity, the circular cavity has a stop block, the locking and releasing arc channel is set in the circular cavity, and the connecting block rotates in the circular cavity and fits against the inner wall of the circular cavity.

[0008] In the aforementioned treadmill column quick disassembly and fixing device, a progressive push structure is provided between the circular cavity and the connecting block. During the process of the screw rotating and the handrail and anti-rotation component moving from being in contact to not being in contact, the progressive push structure causes the connecting block to move outward of the circular cavity along with the screw.

[0009] In the aforementioned treadmill column quick disassembly and fixing device, the progressive push structure includes a horizontal push block disposed within a locking and releasing arc channel, and an arc-shaped segment disposed on the inner surface of the connecting block. The height of the horizontal push block is lower than the height of the abutment block, and the thickness of the arc-shaped segment gradually increases from one end to the other. During the process of the screw rotating to cause the handrail and anti-rotation component to go from being in contact to not being in contact, the horizontal push block pushes the arc-shaped segment to move the screw outward.

[0010] In the aforementioned treadmill column quick disassembly and fixing device, the anti-rotation component and the handrail are provided with several teeth placed at equal intervals, and the gap between two adjacent teeth is adapted to the shape of the teeth.

[0011] In the aforementioned quick disassembly and fixing device for a treadmill column, a handle is provided at the end of the screw away from the nut.

[0012] In the aforementioned quick disassembly and fixing device for a treadmill column, the handle is placed vertically upward and parallel to the handrail when the handrail and anti-rotation component are in contact.

[0013] In the aforementioned quick disassembly and fixing device for a treadmill upright, the nut is restricted from rotating or fixed within the support frame via a slot.

[0014] Compared with existing technologies, the advantages of this utility model are: 1. The handrail, anti-rotation component, and support frame are connected by a screw, and the handrail and anti-rotation component are tightly attached and locked together by tightening the nut, so that the handrail is placed vertically and stably. During use, the anti-rotation component and the handrail are locked together so that the handrail will not wobble. The screw is easy to disassemble, so it is easy to pack and transport separately, reducing the packaging volume.

[0015] 2. The connecting block can slide within the locking and releasing arc channel, thereby limiting the rotation angle of the handrail when adjusting its tightness.

[0016] 3. During the snap-fit ​​process, the teeth on the anti-rotation component are embedded in the gap between adjacent teeth on the handrail, and the teeth on the handrail are embedded in the gap between adjacent teeth on the anti-rotation component, thus forming a double snap-fit ​​structure.

[0017] 4. The handle allows for easy rotation of the screw. During use, the direction of the handle can be directly observed to determine whether the handrail and anti-rotation component are properly aligned, preventing injury during use. Attached Figure Description

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] This embodiment provides a quick disassembly and fixing device for treadmill uprights, combined with... Figure 1-5As shown, the vehicle includes a frame base 10, with support frames 11 on both sides of the frame base 10. The support frames 11 are connected to handrails 12, and the outer side of the handrails 12 is provided with an anti-rotation component 13. When the handrails 12 and the anti-rotation component 13 are in contact, they form a snap-fit. The anti-rotation component 13 can be provided with a through hole 14, which penetrates the support frame 11. The handrails 12 are provided with a screw 15, which penetrates the through hole 14, and the end of the screw 15 away from the handrails 12 is screwed with a nut 16 that fits against the inner side of the support frame 11.

[0022] In this embodiment, when installing the treadmill, the screw 15 passes through the handrail 12, the anti-rotation component 13, and the support frame 11. The tightening of the nut 16 makes the handrail 12 and the anti-rotation component 13 fit tightly together and form a snap-fit, so that the handrail 12 is placed vertically and stably. During use, the snap-fit ​​between the anti-rotation component 13 and the handrail 12 will not cause the handrail 12 to shake. The screw 15 is tightened in to facilitate disassembly, thereby facilitating separate packaging and transportation and reducing the packaging volume.

[0023] The handrail 12 is provided with a locking and releasing arc channel 17. The two ends of the locking and releasing arc channel 17 are provided with end walls. A connecting block 18 is fixed on the screw 15. When the connecting block 18 abuts against one end of the locking and releasing arc channel 17, the handrail 12 and the anti-rotation component 13 are in a close fit. When the connecting block 18 abuts against the other end of the locking and releasing arc channel 17, the handrail 12 and the anti-rotation component 13 are not in a close fit.

[0024] In this embodiment, the connecting block 18 can slide within the locking and releasing arc channel 17, thereby limiting the rotation angle of the armrest 12 in adjusting its tightness.

[0025] The handrail 12 has a circular cavity 19, and the circular cavity 19 has a stop block 20. The locking and releasing arc channel 17 is set in the circular cavity 19, and the connecting block 18 rotates in the circular cavity 19 and fits against the inner wall of the circular cavity 19.

[0026] A progressive structure is also provided between the circular cavity 19 and the connecting block 18. During the process of the screw 15 rotating and the handrail 12 and the anti-rotation component 13 moving from being in contact to not being in contact, the progressive structure causes the connecting block 18 to move outward along with the screw 15.

[0027] In this embodiment, as the screw 15 rotates, causing the handrail 12 and the anti-rotation component 13 to move from being in contact to not being in contact, the progressive pushing structure causes the connecting block 18 to move the screw 15 outward from the circular cavity 19 until the connecting block 18 is pushed out of the circular cavity 19. At this point, the screw 15 can continue to be rotated so that the screw 15 and the nut 16 are disengaged.

[0028] The progressive push structure includes a horizontal push block 21 disposed in the locking and releasing arc channel 17, and an arc segment 22 disposed on the inner surface of the connecting block 18. The height of the horizontal push block 21 is lower than the height of the abutment block 20. The thickness of the arc segment 22 gradually increases from one end to the other. During the process of the screw 15 rotating to make the handrail 12 and the anti-rotation member 13 go from being in contact to not being in contact, the horizontal push block 21 pushes the arc segment 22 to make the screw 15 move outward.

[0029] Both the anti-rotation component 13 and the handrail 12 are provided with a number of equally spaced teeth 23, and the gap between two adjacent teeth 23 is adapted to the shape of the teeth 23.

[0030] In this embodiment, during the snap-fitting process, the teeth 23 on the anti-rotation member 13 are embedded in the gap between adjacent teeth 23 on the handrail 12, and the teeth 23 on the handrail 12 are embedded in the gap between adjacent teeth 23 on the anti-rotation member 13, thereby forming a double snap-fitting structure.

[0031] The end of the screw 15 away from the nut 16 is provided with a handle 24.

[0032] In this embodiment, the handle 24 allows for easy rotation of the screw 15.

[0033] The handle 24 is placed vertically upward and parallel to the handle 12 when the armrest 12 and the anti-rotation component 13 are in contact.

[0034] In this embodiment, the orientation of the handle 24 can be directly observed during use to determine whether the armrest 12 and the anti-rotation component 13 are in contact, thus preventing injury during use.

[0035] The nut 16 is restricted from rotation or fixed within the support frame 11 by a slot. The specific embodiments described herein are merely illustrative examples of the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0036] Although this article frequently uses terms such as frame base 10, support frame 11, handrail 12, anti-rotation component 13, through hole 14, screw 15, nut 16, locking and releasing arc channel 17, connecting block 18, circular cavity 19, stop block 20, horizontal push block 21, arc segment 22, tooth 23, handle 24, etc., these terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any kind of additional limitation would be contrary to the spirit of this utility model.
