Description

Technical Field

[0001] This utility model relates to the field of treadmill technology, and in particular to a treadmill motor fixing structure. Background Technology

[0002] Existing treadmills include a frame with a running belt mounted on it, which is driven by a motor. The motor is fixed to the frame and connected to the running belt shaft via a belt mechanism. The motor and belt mechanism drive the running belt shaft to rotate, which in turn moves the running belt.

[0003] However, in existing treadmills, the belt is prone to loosening during prolonged use. Since the motor is usually directly fixed to the treadmill frame with screws, the motor position cannot be adjusted. Therefore, the belt tension cannot be adjusted by adjusting the motor position, which will cause the belt to slip and reduce transmission efficiency. Summary of the Invention

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, the treadmill motor fixing structure includes a frame 1, a motor 3, and adjusting components 6. The motor 3 includes a motor shaft 3-1 and a motor housing 3-2 that can rotate relative to the motor shaft 3-1. A first pulley 3-3 is provided on the motor housing 3-2, and the first pulley 3-3 is integrally formed with the motor housing 3-2. The adjusting components 6 are respectively provided at both ends of the motor shaft 3-1, and the two ends of the motor shaft 3-1 are connected to the adjusting components 6. A moving adjustment mechanism is provided between the adjusting components 6 and the frame 1, and the moving adjustment mechanism is used to drive the adjusting components 6 to move. A locking mechanism is provided between the adjusting components 6 and the frame 1, and the locking mechanism controls the locking or unlocking of the adjusting components 6.

[0023] This utility model also includes a second pulley 4, and a transmission belt 5 is provided between the second pulley 4 and the first pulley 3-3. The second pulley 4 is coaxially connected to the shaft of the running belt 2; the first pulley 3-3 is driven to rotate by the motor 3, and when the first pulley 3-3 rotates, it drives the second pulley 4 to rotate through the synchronous belt, and the rotation of the second pulley 4 drives the running belt shaft to rotate, and finally drives the running belt 2 to move through the running belt shaft.

[0024] The motor 3 used in this invention is a rotary motor 3. When the motor 3 is running, the motor shaft 3-1 remains fixed, and the motor housing 3-2 rotates around the motor shaft 3-1; the first pulley 3-3 is arranged coaxially with the motor housing 3-2, and when the motor housing 3-2 rotates, it drives the first pulley 3-3 to rotate synchronously.

[0025] In this invention, the installation position of the motor 3 can be adjusted. When the timing belt becomes loose, the locking mechanism releases the adjusting member 6, and then the adjusting member 6 is moved by the moving adjusting mechanism. When the adjusting member 6 moves, it drives the motor shaft 3-1. When the motor shaft 3-1 moves, it drives the motor housing 3-2 and the first pulley 3-3 set on the motor housing 3-2 to move, causing the first pulley 3-3 to move away from the second pulley 4, thereby tightening the timing belt. After the adjustment is completed, the adjusting member 6 is locked and fixed by the locking mechanism. After the adjusting member 6 is locked and fixed, the motor 3 is also fixed. This invention can easily adjust the position of the motor 3, thereby adjusting the tension of the transmission belt 5 and preventing the transmission belt 5 from slipping, which would reduce the transmission efficiency.

[0026] Specifically, the adjusting component 6 includes a limiting body 6-1, which is U-shaped and located on the outer side of the end of the motor shaft 3-1. A fitting spacer 9 is fitted onto the end of the motor shaft 3-1, positioned between the limiting body 6-1 and the motor shaft 3-1. Ear plates 6-2 are respectively provided on both sides of the limiting body 6-1, and each ear plate 6-2 has an adjusting through hole 6-3. The locking mechanism includes a locking screw 10 and a fixing plate 8 mounted on the frame 1. The fixing plate 8 has a threaded hole, and the locking screw 10 passes through the adjusting through hole 6-3 on the ear plate 6-2 and connects to the threaded hole on the fixing plate 8. The adjusting through hole 6-3 is an oblong hole.

[0027] After loosening the locking screw 10, the adjusting part 6 is in the loose state and can be moved. The adjusting through hole 6-3 is an oblong hole, which can ensure that the adjusting part 6 has a certain amount of room to move. After tightening the locking screw 10, the adjusting part 6 is in the locked state and cannot be moved, so the motor 3 cannot be moved either.

[0028] Furthermore, the movable adjustment mechanism includes an adjusting screw 7 and a pull plate 6-5. The pull plate 6-5 is located at the end of one of the ear plates 6-2 on the adjusting component 6. The pull plate 6-5 has an adjusting threaded hole 6-6, and the frame body 1 has an adjusting screw through hole corresponding to the adjusting threaded hole 6-6. The adjusting screw 7 passes through the adjusting screw through hole on the frame body 1 and connects to the adjusting threaded hole 6-6 on the pull plate 6-5. The adjusting screw 7 and the pull plate 6-5 are threadedly engaged. When tensioning the transmission belt 5, rotating the adjusting screw 7 causes the adjusting component 6 to move away from the second pulley 4, thereby tensioning the pulley.

[0029] In this embodiment, the adapter sleeve 9 is made of rubber. Rubber material has a certain shock absorption effect and good insulation properties. Even if the motor 3 leaks current, the current will not be conducted to the metal frame 1 due to the insulation effect of the adapter sleeve 9, thus ensuring safety in use.

[0030] The frame 1 is welded from steel pipes. The adjusting screw through-hole is located on the inner side of the steel pipe on the frame 1, and the outer side of the steel pipe on the frame 1 has an operating hole 1a corresponding to the adjusting screw through-hole. The screw head of the adjusting screw 7 is hidden within the steel pipe. In this invention, the screw head of the adjusting screw 7 is hidden within the steel pipe; this concealed design ensures the treadmill's simple and aesthetically pleasing appearance. The operating hole 1a on the outer side of the steel pipe, corresponding to the adjusting screw through-hole, facilitates the insertion of tools such as a hex wrench into the adjusting screw 7 and its rotation.

[0031] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
