Description

Technical Field

[0001] This utility model belongs to the field of hamster running wheel technology, specifically relating to a magnetically coupled hamster running wheel. Background Technology

[0002] Hamsters are naturally energetic, and their instincts are to run and forage. Wild hamsters are very active animals. If a hamster is deprived of toys for an extended period, its physical functions will decline, and it will only be able to crawl around in its cage. It has been observed that hamsters without a running wheel often channel this energy elsewhere, such as chewing on the cage. Therefore, caged hamsters can increase their activity levels and release their natural instincts by using a running wheel. The design of the running wheel effectively meets the exercise needs of hamsters.

[0003] Existing hamster running wheel devices, such as the magnetically coupled hamster running wheel with announcement number CN219741542U, include a running wheel, a bracket for supporting the running wheel, and a bearing assembly. They address the issues of bearing dust prevention and loosening through structures such as ball-end plungers and sealing rings. Traditional running wheels of this type typically use mechanical locking methods such as screws, clips, or interference fits to fix the running wheel to the axle and bearings.

[0004] However, the aforementioned existing technical solutions still have the following significant drawbacks in practical use: Inconvenient disassembly and maintenance. The running wheel, bearings, and fixed shaft are mostly rigidly locked (e.g., screwed). When the running wheel malfunctions or needs cleaning, specialized disassembly tools such as screwdrivers are required for separation, making the disassembly process cumbersome, time-consuming, and labor-intensive, preventing quick disassembly and replacement. Potential issues with height adjustment and locking. Many running wheels with height adjustment functions have unreliable locking mechanisms (such as simple screw tightening or elastic pin positioning). Under the vibration and impact generated by the hamster's continuous running, the adjustment mechanism is prone to loosening and slippage, leading to unexpected changes in the running wheel height or overall wobbling, producing abnormal noise, affecting user experience and safety. Numerous cleaning dead spots. Complex mechanical connection structures (such as screw holes and slots) easily create unsanitary corners, hiding bedding, dust, and dirt. This not only makes thorough cleaning difficult for users but also allows long-term accumulation of debris to affect the flexibility of rotating parts, exacerbating wear and abnormal noise.

[0005] Therefore, it is necessary to develop a hamster wheel that can achieve quick, tool-based disassembly and assembly and convenient cleaning, and ensure reliable height locking and stable operation after adjustment, in order to overcome the shortcomings of existing technologies. Utility Model Content

[0006] The purpose of this invention is to provide a magnetically coupled hamster wheel 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 coupled hamster wheel, comprising:

[0008] The running wheel body has a running track cavity extending outward on one side for the hamster to run in. The running track cavity has an assembly cylinder slot. The assembly cylinder slot is located on the other side of the running wheel body and extends outward around the slot, with a combined limiting frame for limiting and inserting the running wheel body.

[0009] A support column, the bottom of which is fixedly connected to a base, and the support column is provided with a strip-shaped adjustment lock groove;

[0010] An adjusting lock sleeve consisting of a rear locking sleeve and a front locking sleeve is fitted onto the support upright. Both the front locking sleeve and the rear locking sleeve have connecting holes and are located on the same plane as the strip-shaped adjusting lock groove.

[0011] The first locking device has a fastening post at its rear end, a fixing hole at the end of the fastening post, and a magnetic sleeve at its front end.

[0012] The second locking device has a front end that matches the threaded hole of the fastening post on the first locking device, and a rear end that is a shell for easy gripping.

[0013] A magnetic kit, one end of which can be inserted into the assembly cylindrical slot, can generate a magnetic attraction force that attracts the magnetic sleeve.

[0014] The first locking device is connected to the running wheel body by inserting the magnetic sleeve into the combined limiting frame; the fastening post at the rear end of the first locking device passes through the front locking sleeve, the strip-shaped adjusting locking groove, and the rear locking sleeve in sequence and is locked by the locking post of the second locking device.

[0015] Preferably, one end of the magnetic sleeve extends outward and is provided with a limiting outer ring block that is adapted to the limiting combination of the combined limiting frame.

[0016] Preferably, the fixing method between the rear fastening post of the first locking device and the front locking post of the second locking device can be one of threaded connection, fitting fixation, or snap-fit ​​fixation.

[0017] Preferably, the magnetism of the magnetic sleeve can be generated by its magnetic material or by the magnetic material inside it, and the magnetism of the magnetic kit can be generated by its magnetic material or by the magnetic material inside it.

[0018] Preferably, the magnetic sleeve can rotate independently relative to the first locking fastener.

[0019] Preferably, the fastening post and the strip-shaped adjusting lock groove are fitted with a clearance.

[0020] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0021] By combining magnetic attraction and mechanical locking, a high degree of unity is achieved in convenience, stability, and adjustability. In terms of connection structure, the magnetic attraction between the magnetic sleeve and the magnetic assembly allows the running wheel to be quickly and accurately positioned and connected to the first locking fastener, eliminating the tedious step of aligning screw holes in traditional methods. Simultaneously, the cooperation between the limiting outer ring block and the combined limiting frame ensures the stability of the connection, preventing wobbling during operation. The magnetic sleeve can rotate independently relative to the first locking fastener, achieving quiet and smooth rotation and operation. Regarding adjustment, through the gap fit between the fastening post and the strip-shaped adjustment lock groove, and the adjustment lock sleeve composed of the front and rear locking sleeves, users can easily and continuously adjust the running wheel height simply by loosening the second locking fastener, and then tighten it again for a secure fixation. Its simple and reliable structure greatly improves the flexibility of use and the user experience. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figures 1-11 This utility model provides a technical solution: a magnetically coupled hamster running wheel, including a running wheel body 10. One side of the running wheel body 10 extends outward to form a running track cavity for the hamster to run. The running track cavity has a cylindrical mounting slot 101. A combined limiting frame 102 extends outward from the outer side of the groove on the other side of the running wheel body 10, for limiting and inserting the running wheel body 10. A base 201 is fixedly connected to the bottom of a support rod 20, and a strip-shaped adjusting lock groove 202 is provided on the support rod 20. The adjusting lock sleeve consists of a rear lock sleeve 3 and a front lock sleeve 4, which are fitted onto the support rod 20. Both the front lock sleeve 4 and the rear lock sleeve 3 have connecting holes and are located on the same plane as the strip-shaped adjusting lock groove 202.

[0036] The first locking device 1 has a fastening post 11 at its rear end, a fixing hole at the end of the fastening post 11, and a magnetic sleeve 12 with magnetism at its front end.

[0037] The second locking device 2 has a locking post 21 at the front end that matches the threaded hole of the fastening post 11 on the first locking device 1, and a housing at the rear end for easy gripping.

[0038] One end of the magnetic kit 5 can be inserted into the assembly cylindrical slot 101 and can generate a magnetic attraction force that attracts the magnetic sleeve 12.

[0039] During assembly, the first locking component 1 is inserted into the combined limiting frame 102 via the magnetic sleeve 12 to complete the assembly connection with the running wheel body 10; then, the fastening post 11 at the rear end of the first locking component 1 passes through the connecting hole of the front locking sleeve 4, the strip-shaped adjusting lock groove 202, and the connecting hole of the rear locking sleeve 3 in sequence, and is finally locked by the locking post 21 of the second locking component 2, thereby realizing the adjustable fixation of the running wheel body 10 on the support pole 20, allowing the user to adjust the height of the running wheel by sliding the adjusting sleeve in the strip-shaped adjusting lock groove 202.

[0040] Example 2

[0041] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below, with reference to the specific working method described in detail:

[0042] like Figure 2 and Figure 5 As shown, in a preferred embodiment, one end of the magnetic sleeve 12 extends outward and is provided with a limiting outer ring block 13, which is adapted to the combined limiting frame 102 on the running wheel body 10. When the magnetic sleeve 12 is inserted into the combined limiting frame 102, the limiting outer ring block 13 and the combined limiting frame 102 form a tight limiting combination, effectively preventing relative movement or detachment between the first locking fastener 1 and the running wheel body 10, ensuring connection stability, and facilitating quick assembly and disassembly.

[0043] like Figure 1 As shown, in a preferred embodiment, the fastening post 11 at the rear end of the first locking member 1 and the locking post 21 at the front end of the second locking member 2 can be fixed by one of the following methods: threaded connection, interlocking fixation, or snap-fit ​​fixation. For example, in the threaded connection method, the end of the fastening post 11 is provided with an external thread, and the locking post 21 is provided with a matching internal thread, and fastening can be achieved by rotating the second locking member 2; in the interlocking fixation method, the fastening post 11 and the locking post 21 are designed as interlocking convex and concave structures; in the snap-fit ​​fixation method, quick locking is achieved through snap-fit ​​and slot, providing multiple implementation methods.

[0044] like Figure 1 As shown, in a preferred embodiment, the magnetism of the magnetic sleeve 12 can be generated by its own material, such as a permanent magnet material like neodymium iron boron, or by a magnetic material embedded inside it, such as a magnet fixed inside a plastic shell. Similarly, the magnetism of the magnetic kit 5 can also be generated by its own magnetic material or by a magnetic material provided inside it, thereby ensuring a strong magnetic attraction between the magnetic sleeve 12 and the magnetic kit 5, making the connection between the running wheel body 10 and the first locking fastener 1 reliable and easy to separate.

[0045] like Figure 1As shown, in a preferred embodiment, the magnetic sleeve 12 can rotate independently relative to the first locking fastener 1. When the running wheel body 10 is attracted to the magnetic sleeve 12 by the magnetic kit 5, the running wheel body 10 can rotate freely, while the first locking fastener 1 remains stationary.

[0046] like Figure 1 As shown, in a preferred embodiment, the fastening post 11 is fitted with the strip-shaped adjustment lock groove 202 with a clearance fit. Furthermore, the diameter of the fastening post 11 is slightly smaller than the width of the strip-shaped adjustment lock groove 202, allowing the fastening post 11 to slide smoothly within the strip-shaped adjustment lock groove 202. This facilitates the user in adjusting the height of the running wheel body 10. Once adjusted to the ideal position, it can be fixed by locking it with the second locking fastener 2. The clearance fit ensures the flexibility and stability of the adjustment.

[0047] The workflow of this utility model begins with overall assembly: First, the magnetic kit 5 is inserted into the assembly cylindrical slot 101 of the running wheel body 10 and fixed. Next, the magnetic sleeve 12 at the front end of the first locking fastener 1 is aligned and attracted to the magnetic kit 5 already installed on the running wheel. At the same time, the limiting outer ring block 13 on the first locking fastener 1 is embedded in the combined limiting frame 102 of the running wheel body 10, thereby achieving a quick and stable connection between the running wheel body 10 and the first locking fastener 1. Then, the rear locking sleeve 3 and the front locking sleeve 4 fitted on the support pole 20 are adjusted to the desired height so that their connection holes are aligned with the strip-shaped adjustment lock groove 202 on the support pole 20. Subsequently, the fastening post 11 at the rear end of the first locking fastener 1 is passed sequentially through the connection hole of the front locking sleeve 4, the strip-shaped adjustment lock groove 202, and the connection hole of the rear locking sleeve 3. Finally, the locking pin 21 at the front end of the second locking pin 2 and the fastening pin 11 at the rear end of the first locking pin 1 are locked together by means of threaded connection, thereby firmly fixing the entire running wheel assembly to the support pole 20. When the hamster runs in the running track cavity of the running wheel body 10, the running wheel body 10 will rotate smoothly around the first locking pin 1 through the magnetic attraction connection between the magnetic kit 5 and the magnetic sleeve 12.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
