Description

Technical Field

[0001] The utility model relates to the technical field of trainers, in particular to a magnetic resistance type upper limb trainer. Background Technique

[0002] With the development of national fitness, people's requirements for outdoor fitness equipment have also increased. Most of the existing outdoor upper limb trainers are composed of a rotating shaft and a rotating plate. There is usually no resistance or mechanical damping is provided between the rotating shaft and the rotating plate, resulting in limited training effect. It is not convenient to adjust the damping size, which affects the user experience. For example, the patent with the publication number CN220609010U discloses an intelligent magnetic resistance upper limb trainer, including a support frame and a magnetic resistance upper limb trainer body. Its characteristics are: at least two magnetic resistance upper limb trainer bodies are connected to the support frame. The magnetic resistance upper limb trainer body includes a housing, an aluminum flywheel, a rotating shaft, a crank, a magnet group A, a magnet group B and a column. The upper end of the column is connected to the housing. Magnet groups A and B with different magnetic poles are respectively arranged on two opposite inner side surfaces in the housing. The aluminum flywheel is arranged in the housing through the rotating shaft. The rotating shaft is perpendicular to two opposite inner side surfaces of the housing. The rotating shaft is connected to the crank outside the housing. The crank is used to drive the rotating shaft to drive the aluminum flywheel to rotate. The aluminum flywheel is used to cut the magnetic induction lines generated by the magnet group A and the magnet group B when it rotates, so as to generate a rotational resistance. This device has a simple and compact structure, occupies a small area, and has a good damping effect. However, due to the action of electromagnetic force, after the hand leaves the device, the aluminum flywheel will immediately rotate back a certain angle and then enter a swinging state, which is easy to cause accidental injury to users. And the device can only rotate, and the use effect is relatively single.

[0003] Therefore, the utility model provides a magnetic resistance type upper limb trainer. Content of the Utility Model

Detailed Embodiment

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please refer to Figures 1 to 5 , the present utility model provides a technical solution: a magnetoresistive upper limb trainer, including a base 1, a support rod 2 is installed on the base 1, the support rod 2 is a telescopic structure, one end of the support rod 2 is installed with a fixed plate 3, a rotating housing 4 is rotatably matched on the fixed plate 3, a plurality of electromagnets 5 are fixed on the fixed plate 3, the rotating housing 4 corresponds to the support rod 2, a limiting structure is installed between the rotating housing 4 and the fixed plate 3, and pressing training structures are installed on both the upper side of the rotating housing 4 and the lower side of the fixed plate 3.

[0023] In this embodiment, the support rod 2 includes a telescopic rod 201, connecting rods 202 are fixed at both ends of the telescopic rod 201, the two connecting rods 202 are respectively fixedly connected to the base 1 and the fixed plate 3, the connecting rod 202 at the top is rotatably connected to the rotating housing 4, and a bearing 6 is installed between the connecting rod 202 and the rotating housing 4.

[0024] Specifically, the overall height of the device can be adjusted by adjusting the length of the telescopic rod 201, so that the device is suitable for people of different heights.

[0025] A rotating groove 7 is formed in the fixing plate 3, and the rotating groove 7 corresponds to the rotating outer shell 4. The limiting structure includes a plurality of first limiting blocks 8 and a plurality of second limiting blocks 9. The first limiting blocks 8 are fixed on the peripheral side of the rotating outer shell 4, and the second limiting blocks 9 are fixed on the peripheral side in the rotating groove 7. Both the first limiting blocks 8 and the plurality of second limiting blocks 9 are in an inclined triangular structure, the first limiting blocks 8 correspond to the second limiting blocks 9, and both the first limiting blocks 8 and the second limiting blocks 9 are made of elastic materials.

[0026] Specifically, when the rotating outer shell 4 is rotated, the electromagnet 5 is energized, so that the rotating outer shell 4 cuts the magnetic induction lines, and a certain damping force can be applied to the rotating outer shell 4, thereby increasing the training difficulty.

[0027] When the rotating outer shell 4 rotates, the first limiting blocks 8 are driven by the rotating outer shell 4 to rotate together. There is a certain friction between the second limiting blocks 9 and the first limiting blocks 8, thereby increasing the damping force. When the rotation stops, at this time, the second limiting blocks 9 limit the first limiting blocks 8, thereby preventing the rotating outer shell 4 from rotating back or continuing to rotate by inertia, so that the rotating outer shell 4 can stop immediately, thereby preventing harm to the user.

[0028] The pressing training structure includes support blocks 14 fixed on the upper side of the rotating outer shell 4 and the lower side of the fixing plate 3. A pressing sleeve 10 is slidably fitted on the support blocks 14. A limiting ring 13 is fixed on the peripheral side of the support blocks 14, and the limiting ring 13 corresponds to the pressing sleeve 10. A first magnet 11 is fixed on the support blocks 14, and a second magnet 12 is fixed in the pressing sleeve 10. The magnetic poles of the opposite sides of the first magnet 11 and the second magnet 12 are the same.

[0029] Specifically, when performing pressing training, the upper pressing sleeve 10 is pressed downward or the lower pressing sleeve 10 is pressed upward, so that the second magnet 12 approaches the first magnet 11, and the second magnet 12 repels the first magnet 11, thereby achieving a better training effect.

[0030] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only includes an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
