Description

Technical Field

[0001] The utility model relates to the technical field of animal running wheels, in particular to a hamster running wheel. Background Art

[0002] As economic prosperity improves, people are beginning to prioritize spiritual independence, and more and more people are willing to live alone. This has led to a surge in pet companionship, shifting from medium- to large-sized pets to smaller, adorable pets. These smaller pets are easier to care for and more suitable for both young and old, leading to a surge in popularity. For example, the most common hamster, with its low maintenance requirements and low cost, high survival rate, and its active nature that brings joy to owners, has consistently ranked among the top small pets. Hamsters are typically kept in small cages, lacking the freedom of movement enjoyed by larger pets. This lack of exercise can reduce their mobility and shorten their lifespan over time. Fitness training can improve their mobility, making specialized hamster wheels essential and in high demand.

[0003] The current hamster running wheels mainly have the following problems:

[0004] The structural design is complex, which will lead to an increase in cost. Referring to a new hamster running wheel device disclosed in patent number CN202220893657.5, although the patent has been slightly improved, it still requires multiple manual thread adjustments to achieve overall assembly or disassembly. For example, the technical content disclosed therein: "A first external thread 31 can be provided on the outer wall of one end of the mounting shaft 3, and a first horizontally arranged threaded hole 222 is recessed on the outer wall of the adjusting sleeve 22. One end of the mounting shaft 3 is inserted into the first threaded hole 222 of the adjusting sleeve 22 and is threadedly connected to the first threaded hole 222, thereby being connected to the adjusting sleeve 22. The mounting shaft can also be connected to the adjusting sleeve by other connection methods, which are not limited to this embodiment.

[0005] And it is also mentioned in the embodiment: "A transverse first screw hole 221 is provided through the wall of the adjustment sleeve 22, and the first locking screws 23 are respectively threadedly connected to the corresponding first screw holes 221 and lock the outer wall of the mounting column 21, thereby locking the adjustment sleeve 22 on the mounting column 21. Among them, in other embodiments, in order to enable the adjustment sleeve to be more firmly locked on the mounting column, the number of first locking screws can be increased according to user needs, which is not limited to this embodiment." Obviously, although this document no longer requires the use of instruments to unscrew or tighten the screws when disassembling or installing the running wheel body, there are many steps for disassembling and assembling the screws on other structures, and there is no actual overall improvement to simplify the structure of the hamster running wheel.

[0006] 2. The design of the bracket adjustment structure is unreasonable, which reduces the effectiveness of the overall structure. Referring to a hamster running wheel disclosed in patent number CN201921368504.3, it is disclosed that: "The butterfly nut 8 is connected to the proximal bracket end 31 of the axial mechanism 32 to lock the axial mechanism 32 on the support portion 23. The rotating mechanism 3 and the support frame 2 can be conveniently loosened / locked by the butterfly nut 8, and the strip-shaped through hole 231 cooperates with the axial mechanism 32." However, analysis shows that because the butterfly nut 8 and the axial mechanism 32 in this document are too small, compared with the volume of the running wheel body 1, the strip-shaped through hole 231 is obviously not enough to generate a large friction resistance to clamp the front and back sides to fix the running wheel body 1, which makes the rationality of this document questionable.

[0007] Therefore, in view of the above-mentioned current situation, it is urgent to develop a novel hamster running wheel to meet the needs of actual use. Utility Model Content

[0008] In view of the deficiencies in the prior art, the utility model provides a hamster running wheel.

DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] refer to Figure 1-4 A hamster running wheel includes a base 100, a bracket 200 and a runway 300. The runway 300 is connected to the bracket 200 through a connecting shaft 600. The bracket 200 is provided with an adjustment slide 201 for adjusting the connecting shaft 600 up and down. The two ends of the connecting shaft 600 are respectively connected to a protective cap 400 and an adjustment knob 500. The bottom end of the bracket 200 is fixedly connected to one side of the base 100. A reinforcement 101 is provided at the fixed connection between the bracket 200 and the base 100.

[0030] Of particular note is the presence of a closed disk on one side of the runway 300, with a bearing assembly 800 located on the back. The bearing assembly 800 includes a first bearing 801 and a second bearing 802, with a plastic sleeve 803 positioned between the first and second bearings 801 and 802. A stopper 804 is located on the inner wall of the bearing assembly 800, between the first and second bearings 801 and 802. The stopper 804 within the bearing assembly 800 is intended to prevent the bearings from shifting. The plastic sleeve 803 is intended to prevent the inner and outer rings of the bearings from misaligning. Based on actual feedback from past product sales users, if two bearings are placed side by side without the plastic sleeve 803 or other retaining rings to limit their position, tightening the screws will cause the outer and inner rings of the bearings to become misaligned, resulting in the bearings becoming misaligned and unable to rotate. Therefore, the provision of the plastic sleeve 803 in this patent is essential.

[0031] At the same time, one end of the connecting shaft 600 is set to pass through the closing disk of the runway 300 to fix the protective cap 400, and the other end of the connecting shaft 600 passes through the No. 1 bearing 801, the plastic sleeve 803, the No. 2 bearing 802 and the bracket 200 in sequence to be connected to the adjusting knob 500; the end of the other end of the connecting shaft 600 is set as an external threaded column 601, and the adjusting knob 500 is provided with an internal thread groove 501, and the external threaded column 601 of the connecting shaft 600 is threadedly connected to the adjusting knob 500; a positioning member 700 is provided between the bearing assembly 800 and the bracket 200, and the positioning member 700 forms a conical structure around the connecting shaft 600 on a side close to the bearing assembly 800.

[0032] Finally, the upper and lower ends of the adjustment slide 201 on the bracket 200 are designed as semicircular notches, and the semicircular notches are connected by rectangular notches; rubber pads 202 are provided around the adjustment slide 201 on the front and rear sides of the bracket 200, and the coverage area of the rubber pads 202 is equal to the coverage area of the sliding adjustment of the adjustment knob 500 and the positioning member 700; the side of the adjustment knob 500 close to the bracket 200 is provided with a rubber layer, and the side of the positioning member 700 close to the bracket 200 is provided with a rubber layer; the protective cover The diameter of the cap 400 and the positioning member 700 is larger than the diameter of the bearing assembly 800; through the above arrangement, compared with the prior art documents, the rubber layer on the adjusting knob 500 and the positioning member 700 in this patent and the rubber pad 202 on the bracket 200 form resistance to each other, and the adjusting knob 500 and the positioning member 700 are further clamped by threads, and the friction force on the bracket 200 is much greater than the total weight of the runway 300 plus the weight of the hamster. Therefore, the new hamster running wheel with a simple structure and light weight of this patent has a reasonable design and a stable overall structure.

[0033] The utility model only sets one end of the connecting shaft to pass through the closed disk of the runway to fix the protective cover cap, and the other end passes through the No. 1 bearing, the plastic sleeve, the No. 2 bearing and the bracket in sequence to be connected to the adjusting knob. The external threaded column of the connecting shaft is threadedly connected to the internal threaded groove of the adjusting knob, and a positioning piece is provided between the bearing assembly and the bracket. This is sufficient to make the structure of the entire hamster running wheel complete and simple in structure. It is not only convenient to install and disassemble, but also helps to reduce production costs and improve market competitiveness.

[0034] The present utility model improves the defects in the existing technology of pet running wheels by arranging a plastic sleeve between the bearings, and setting a limit block on the inner wall of the bearing assembly and between the bearings. The limit block in the bearing assembly is used to prevent the bearing from shifting, and the plastic sleeve is set to prevent the inner and outer rings of the bearing from being misaligned. According to actual feedback from past product sales users, if two bearings are set side by side without a plastic sleeve or other retaining ring for limiting, the outer and inner rings of the bearings will not be in line when the screws are tightened, resulting in the bearings being misaligned and unable to rotate. Therefore, the plastic sleeve set here in this patent can effectively solve the problem of the bearings being misaligned and unable to rotate.

[0035] The utility model improves the structural defects of the existing technology by setting the diameter of the protective cap and the positioning part to be larger than the diameter of the bearing assembly, and the rubber layer on the adjusting knob and the positioning part and the rubber pad on the bracket to form resistance with each other. The adjusting knob and the positioning part are further clamped by the thread, and the friction force on the bracket is much greater than the total weight of the runway and the hamster. Therefore, this patented new hamster running wheel with a simple structure and lightweight quality has a reasonable design and a stable overall structure.
