Description

Technical Field

[0001] This utility model belongs to the field of treadmill technology, and in particular relates to a magnetic resistance device for treadmills. Background Technology

[0002] Treadmills are a common type of fitness equipment. Based on their power source, they can be divided into three types: electric treadmills, mechanical treadmills, and magnetic control treadmills. Both mechanical and magnetic control treadmills are equipped with magnetic resistance devices, which are used to adjust the resistance and thus meet the needs of different users.

[0003] Existing magnetic resistance devices mainly consist of three parts: a magnet support, an adjustment structure, a magnet, and a flywheel. Multiple magnets are installed within the magnet support via the adjustment structure, with the magnets located on the outside of the flywheel. During use, the distance between the magnets and the flywheel is adjusted using the adjustment structure, thereby regulating the resistance. However, since the magnets and adjustment structure are typically connected by bolts, it is inconvenient to install and disassemble the magnets, making it difficult to replace magnets that have lost or weakened their magnetism. Furthermore, over long periods of use, dust easily accumulates on the flywheel, and the presence of dust affects the eddy current effect between the magnets and the flywheel, thus impacting the flywheel's resistance.

[0004] To address these issues, we provide a magnetic resistance device for treadmills. Utility Model Content

[0005] The purpose of this invention is to provide a magnetic resistance device for a treadmill. The device limits the permanent magnet vertically using upper and lower clamps, and further limits it horizontally using fixed and movable clamps, thus fixing the permanent magnet to the adjustment plate. This solves the problem of inconvenient installation and removal of the permanent magnet in existing systems. Simultaneously, the third threaded rod drives the U-shaped frame and sponge to move, allowing the sponge to contact the flywheel and clean the dust on it, thus solving the problem of inconvenient cleaning of dust on the flywheel in existing systems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

An adjustment assembly is provided on the inner side of the support frame, including an adjustment plate movably connected to the inner side of the support frame. Upper and lower clamping plates are welded to the upper and lower surfaces of the adjustment plate, and a permanent magnet is clamped between the upper and lower clamping plates. A fixed clamping plate is clamped to the rear end of the permanent magnet, and a movable clamping plate is clamped to the front end of the permanent magnet. The fixed clamping plate is fixedly connected to the rear end of one side of the outer wall of the adjustment plate.

One end of the first threaded rod extends to the inner side of the bracket and is fixedly connected to the center of the outer wall of the other side of the adjustment plate. The other end of the first threaded rod is fixedly connected to a first knob.

[0010] A further feature of this invention is that: a limiting rod is fixedly connected to both the upper and lower sides of the outer wall on the other side of the adjusting plate, and the end of the limiting rod away from the adjusting plate passes through the mounting block and is fixedly connected to the limiting plate.

[0011] A further feature of this invention is that grooves are provided on both the upper and lower sides of the outer wall of one side of the adjusting plate, and protrusions are movably connected inside the grooves. The ends of the protrusions located outside the grooves are fixedly connected to the outer wall of one side of the movable clamping plate.

[0012] A further feature of this invention is that: a locking block is welded to one side of the outer wall of both the fixed clamping plate and the movable clamping plate, and the free end of the locking block is attached to the outer wall of the permanent magnet away from the adjusting plate.

[0016] 1. This utility model, by setting an adjustment component, first places the permanent magnet between two upper and lower clamping plates, so that the rear end of the permanent magnet is engaged with the front end face of the fixed clamping plate. Then, the second knob is rotated, which drives the second threaded rod to rotate. The second threaded rod drives the moving clamping plate to move, so that the moving clamping plate is engaged with the front end of the permanent magnet, thereby fixing the permanent magnet on the adjustment plate. This facilitates the installation and disassembly of the permanent magnet and makes it convenient to replace permanent magnets that have lost or weakened magnetism.
