Description

Technical Field

[0001] This utility model relates to the field of animal running wheels, and more specifically, to a magnetically fixed animal running wheel structure. Background Technology

[0002] Animals in cages can increase their activity level and release their natural instincts by running on running wheels. While running wheels are designed to meet the animals' exercise needs, existing animal running wheel devices are unreliable and offer a poor user experience. With continued use, the inertia of the rotating wheel can cause the axle system to become unstable, leading to significant shaking, abnormal noises, and even malfunction. Furthermore, the bedding materials such as paper and cotton inside the cages contain dust, which can be stirred up and enter the running wheel's axle system when the animal runs on it, also causing bearing noises and 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 wheels are locked to the bearings and fixed shafts, and when the running wheels malfunction, disassembly tools are required to separate them, which makes disassembly and repair more troublesome and time-consuming. Therefore, it is not possible to quickly disassemble and replace the running wheels and fixed shafts in a simple and quick way. In addition, dirt and grime can easily accumulate in the gaps of the connecting parts in the track groove.

[0005] Therefore, a magnetically fixed animal running wheel structure is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a magnetically fixed animal running wheel structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a magnetically fixed animal running wheel structure, comprising a running wheel body, a connecting plate, and a fixed base. A circular deep groove is formed on the front surface of the running wheel body, and an anti-slip running track is formed on the side of the circular deep groove. A connecting plate is provided on the rear side of the running wheel body, and a threaded hole is formed on the connecting plate. A screw is screwed through the threaded hole into a pre-reserved threaded groove on the rear surface of the running wheel body to achieve a fixed connection with the running wheel body. A connecting post is provided in the middle of the rear surface of the connecting plate, and a connecting groove is formed from back to front on the connecting post. A first magnetic attractor is provided inside the connecting groove. A vertical rod is provided at the rear of the top surface of the fixed base, and an adjusting lock sleeve is sleeved on the vertical rod. Through holes are formed on the front and rear sides of the adjusting lock sleeve, through which a rotating shaft is inserted. A combined magnetic attractor is fixedly connected to the front end of the rotating shaft, and two bearings are sleeved on its outer side. Steel sleeves are sleeved on the bearings.

[0008] Preferably, the connection method between the first magnetic suction component and the connecting groove includes fixing by mechanical fasteners or direct bonding, which can withstand radial and axial loads.

[0009] Preferably, the second magnetic accumulator is a neodymium iron boron magnet, which can generate a strong attraction force on the first magnetic accumulator, which is an iron block or a magnet.

[0010] Preferably, the front and rear surfaces of the upright are provided with through sliding adjustment grooves, and the corners inside the grooves are all rounded. The width of the sliding adjustment groove is the same as that of the rotating shaft. When the adjusting lock sleeve is fitted onto the upright, the rear end of the rotating shaft passes through the sliding adjustment groove to the rear side of the adjusting lock sleeve, and a locking cap is screwed onto the thread reserved on the rear side of the shaft.

[0011] Preferably, a limiting groove is provided at the opening of the connecting groove, and a limiting block is also provided on the steel sleeve. The size of the steel sleeve matches the size of the connecting groove, and the size of the limiting block matches the size of the limiting groove. The surface of the steel sleeve can be tightly fitted to the surface of the connecting column.

[0012] Preferably, handles are provided on both sides of the connecting plate.

[0013] Preferably, the running wheel body can be customized in color and shape.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] Compared with existing technologies, this device creates a running track by opening a circular deep groove on the running wheel body, and fixes it to the connecting plate at the rear with screws. This structure allows the running wheel body to be disassembled separately for cleaning, and there are no other connecting parts in the circular deep groove where the running track is located, making it less likely to accumulate dirt. It is further equipped with connecting columns, connecting grooves, combined magnetic components, rotating shaft, steel sleeve, and bearings. The steel sleeve is clamped and fixed to the bearing by the magnetic attraction of the combined magnetic components, so that the running wheel body and connecting sleeve can rotate with the steel sleeve on the rotating shaft. The installation and limiting fixation by magnetic attraction can be quick to install and quick to disassemble, improving the convenience of disassembly and assembly. Attached Figure Description
