Abstract
Description
Technical Field
[0001] This utility model relates to the field of animal running wheels, and more specifically, to an animal running wheel fixing device based on magnetic coupling. Background Technology
[0002] When keeping small animals in cages, animal running wheels are often used to increase their activity level and allow them to release their natural instincts. While running wheels are designed to meet the exercise needs of small animals, existing running wheel systems are often unreliable and offer a poor user experience. With continued use, the inertia of the rotating wheel can cause problems with the axle system's stability. Furthermore, the bedding materials inside the cage, such as paper or cotton, can generate dust. This dust can be stirred up during running and enter the running wheel's axle system, leading to abnormal bearing noise and potential malfunction.
[0003] Therefore, a hamster running wheel with announcement number "CN219741542U" includes a running wheel, a bracket for supporting the running wheel, and a bearing assembly. The bracket has a mounting groove, and both ends of the bearing assembly pass through the running wheel and the mounting groove, respectively. The running wheel is rotatably connected to the bracket via the bearing assembly. The bearing assembly includes a bearing, a sealing ring, a ball-head plunger, a bearing housing, and a bearing housing cover. The bearing is movably disposed inside the bearing housing, the bearing housing cover is disposed on one side of the bearing housing, and the sealing ring is disposed on one side of the bearing. The bearing housing has a fixing groove for the ball-head plunger to pass through, and the bearing housing cover has several spherical grooves for fixing the ball-head plunger. One end of the ball-head plunger is fixedly connected to the fixing groove, and the end of the ball-head plunger with a ball head is movably connected to the spherical groove. The sealing ring effectively prevents dust and sand from entering the bearing, and the ball-head plunger effectively prevents the bearing housing cover from loosening from the bearing housing, thus making this hamster running wheel stable and durable.
[0004] However, the above-mentioned animal running wheels still have the following obvious defects during use: the running wheel is locked to the bearing and the fixed shaft, and when the running wheel fails, it is necessary to use disassembly tools to separate the two. Therefore, disassembly and repair are troublesome and time-consuming, and it is not possible to quickly disassemble and replace the running wheel and the fixed shaft in a simple and quick way. In addition, dirt and grime can easily accumulate inside the running wheel.
[0005] Therefore, an animal running wheel fixing device based on magnetic coupling is proposed to address the above problems. Utility Model Content
[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an animal running wheel fixing device based on magnetic coupling to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an animal running wheel fixing device based on magnetic coupling, comprising a running wheel body and a support pole. The outer ring of the front surface of the running wheel body extends outward to form an annular track. A cylindrical block is provided at the center of the front surface of the running wheel body. The rear side of the cylindrical block extends to the rear side wall of the running wheel body, and a circular groove is provided on its rear side. A first combination magnetic attractor is fixedly connected to the circular groove in a non-detachable manner. An adjusting lock sleeve is sleeved on the support pole. The adjusting lock sleeve has through holes on its front and rear sides, through which a magnetic shaft is inserted. Two bearings are sleeved at the front end of the magnetic shaft. A steel sleeve is sleeved on the bearings. A second combination magnetic attractor is provided at the front end of the steel sleeve. The second combination magnetic attractor can attract the magnetic shaft and the first combination magnetic attractor.
[0008] Preferably, the fixed connection between the combined magnetic component and the circular groove includes fixing by mechanical fasteners or direct bonding, which can withstand radial and axial loads.
[0009] Preferably, at least one of the combined magnetic component one and the combined magnetic component two is a magnetic body, and the two can attract each other.
[0010] Preferably, the front and rear surfaces of the support pole are provided with through strip-shaped adjustment grooves, and the corners of the grooves are rounded. The width of the strip-shaped adjustment groove is the same as that of the magnetic shaft. When the adjustment lock sleeve is fitted onto the support pole, the rear end of the magnetic shaft passes through the strip-shaped adjustment groove to the rear side of the adjustment lock sleeve, and a lock cap is screwed onto the thread reserved on the rear side.
[0011] Preferably, the size of the steel sleeve matches the circular groove, and its front surface and side surface can fit tightly against the circular groove.
[0012] Preferably, the front side of the cylindrical block is provided with a connecting groove, and the inner wall of the connecting groove is threaded, on which a front sleeve with a matching thread is screwed.
[0013] Preferably, a connecting ring is provided on the rear surface of the adjusting lock sleeve, the connecting ring is located on the outer ring of the lock cap, and a rear sleeve is sleeved on its outer side.
[0014] The technical effects and advantages of this utility model are as follows:
[0015] Compared with existing technologies, this device features an integrated running wheel structure, directly extending outward from one side of the running wheel body to create a circular track, instead of connecting the separate running wheel and track with connectors. This eliminates the problem of dirt accumulation caused by connecting structures, making it easier for users to clean. The device incorporates cylindrical blocks, circular grooves, combined magnetic components, a magnetic shaft, a steel sleeve, and bearings, forming a magnetically connected structure. The running wheel body is magnetically fixed to the steel sleeve, which in turn is fixed to the bearing by the magnetic shaft. Utilizing magnetic force for installation and limiting fixation, it allows for quick assembly and disassembly, improving the convenience of installation and disassembly. Attached Figure Description
