AI Technical Summary
In existing fitness bikes, magnets are usually fixed on the magnet stand by glue bonding, which is troublesome to operate and not stable enough, and is prone to fall off due to aging of glue.
A new magnet rack structure is designed, including a magnet rack, a limit cover and several magnets. The limit cover is locked on the lower surface of the magnet frame by screws, forming a mounting groove to secure the magnet, ensuring that the magnet is securely installed.
It realizes the firm installation of the magnet on the magnet stand, with simple operation and no need to wait for the glue to solidify, high efficiency and stable structure, avoiding the problems of magnet falling out and unstable resistance.

Description
Technical Field
[0001] The utility model relates to the technical field of fitness vehicles, in particular to a novel magnet frame structure. Background Art
[0002] An exercise bike, also known as an indoor bike or spinning bike, is a popular piece of aerobic exercise equipment used for cardiorespiratory exercise at home and in gyms. It simulates the experience of riding a bicycle, but allows users to exercise in a comfortable indoor environment, unaffected by weather and traffic conditions.
[0003] The resistance of an exercise bike is usually determined by a metal flywheel and a magnet that matches the flywheel. The magnet is installed in the exercise bike through a magnet frame and is located on the circumference of the flywheel. The position of the magnet frame can be adjusted by operating the adjustment mechanism, thereby adjusting the distance between the magnet and the flywheel, thereby providing different resistances.
[0004] In the prior art, magnets are usually fixed on the magnet frame by gluing, which is troublesome to operate. In addition, since the magnets are usually glued to the bottom surface of the magnet frame, they may fall off after a long period of use due to aging of the glue, and the structure is not stable enough. Utility Model Content
[0005] The purpose of the utility model is to provide a novel magnet frame structure, which solves the problems existing in the prior art, is easy to assemble, and can realize the firm installation of the magnet on the magnet frame.
[0006] In order to achieve the above purpose, the solution of the utility model is:
[0007] A novel magnet frame structure comprises a magnet frame, a limit cover and a plurality of magnets; the limit cover is screwed to the lower surface of the magnet frame by a plurality of screws, and a side facing the magnet frame is recessed to form a plurality of mounting grooves, the bottom of the mounting groove is provided with a bottom opening, and the side of the mounting groove is provided with a side opening for the magnet to enter and exit the mounting groove; the inner wall of the bottom opening is provided with a plurality of limit flanges for limiting the magnet; the magnet enters the limit cover pre-installed on the magnet frame through the side opening, and is clamped on the magnet frame by the limit cover to achieve fixation after the screws are tightened.
[0008] Screws are arranged at both ends and the middle position of the limiting cover.
[0009] The side openings are divided into two groups and are respectively arranged on both sides of the limiting cover.
[0010] The limiting cover is provided with a through hole for the screw to pass through, and the magnet frame is provided with a screw hole for the screw to be threadedly connected.
[0011] After adopting the above technical solution, the utility model has the following technical effects:
[0012] During assembly, the utility model can pre-install the limit cover on the magnet frame, and then install the magnets into the corresponding installation grooves one by one through the side openings, and then tighten the screws so that the limit cover and the magnet frame clamp the magnets towards each other, thereby realizing the installation of the magnets on the magnet frame. The whole process is simple to operate, and there is no need to wait for the glue to solidify. The magnets can be installed and used immediately, with high efficiency and firm structure. The bottom opening of the installation groove does not affect the external output of the magnetic force of the magnet, so that the resistance provided by the magnet to the flywheel of the fitness bike is stable, and the limit flange can prevent the magnet from falling out of the installation groove.

[0018] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.
[0019] refer to Figures 1 to 3 As shown, the utility model discloses a novel magnet frame structure, comprising a magnet frame 1, a limiting cover 2 and a plurality of magnets 3;
[0020] The limiting cover 2 is fixed to the lower surface of the magnet frame 1 by a plurality of screws 4, and a plurality of mounting grooves 21 are formed in a recessed manner on a side facing the magnet frame 1. A bottom opening 211 is provided at the bottom of the mounting groove 21 to connect to a side of the limiting cover 2 facing away from the magnet frame 1, and a side opening 212 is provided on the side of the mounting groove 21 for the magnet 3 to enter and exit the mounting groove 21; a plurality of limiting flanges 2111 for limiting the magnet 3 are provided on the inner wall of the bottom opening 211;
[0021] The magnet 3 enters the limiting cover 2 pre-installed on the magnet frame 1 through the side opening 212 and is clamped on the magnet frame 1 by the limiting cover 2 after the screw 4 is tightened to achieve fixation.
[0022] Through the above scheme, during assembly, the utility model can pre-install the limit cover 2 on the magnet frame 1, and then install the magnets 3 into the corresponding installation grooves 21 one by one through the side openings 212, and then tighten the screws 4 so that the limit cover 2 and the magnet frame 1 clamp the magnets 3 towards each other, thereby realizing the installation of the magnets 3 on the magnet frame 1. The whole process is simple to operate, and there is no need to wait for the glue to cure. It is ready to use after installation, with high efficiency and firm structure. The bottom opening 211 of the installation groove 21 does not affect the external output of the magnetic force of the magnet 3, ensuring that the resistance provided by the magnet 3 to the flywheel of the fitness bike is stable, and the limit flange 2111 can prevent the magnet 3 from falling out of the installation groove 21.
[0023] Specific embodiments of the present utility model are shown below.
[0024] Screws 4 are provided at both ends and the middle position of the above-mentioned limit cover 2. The limit cover 2 is locked by at least three screws 4, which makes the structure more solid and can prevent the middle position of the limit cover 2 from being compressed and deformed due to the gravity of the magnet 3, thereby preventing the magnet 3 from loosening.
[0025] The side openings 212 are divided into two groups and are respectively arranged on both sides of the limiting cover 2 to avoid opening holes on only one side of the limiting cover 2 which would cause a decrease in strength on one side, thereby ensuring the stability of the overall structure of the limiting cover 2.
[0026] The limiting cover 2 is provided with a through hole 22 for the screw 4 to pass through, and the magnet frame 1 is provided with a screw hole 11 for the screw 4 to be threadedly connected.
[0027] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
