Description

Technical Field

[0001] This utility model relates to the field of pet running wheel technology, and in particular to a novel snap-fit ​​device for a pet running wheel. Background Technology

[0002] With the increasingly sophisticated development of the pet breeding market, the demand for functionality and safety of pet activity products continues to rise. Among them, pet running wheels, as core exercise equipment, have become a key pain point for users in terms of structural stability and adaptability. In recent years, as the scale of pet breeding has expanded, the types of pets have also expanded from traditional small hamsters to medium and large pets, which has placed higher demands on the load-bearing capacity and assembly stability of running wheels.

[0003] Currently, most pet running wheels on the market use a "snap fastener" connection method. The fastening point is concentrated on the edge of the wheel, and the fastener is fixed only by friction. When large pets use the wheel, the lateral tension and radial pressure generated by the rotation of the wheel will be concentrated at the fastening point, which can easily cause the snap fastener to fall off or break. This not only affects the lifespan of the running wheel, but may also cause pets to get pinched or fall. Based on this, a new type of fastening device for pet running wheels is proposed for improvement. Utility Model Content

[0004] In view of the safety and durability issues of traditional snap-fit ​​pet wheels in the context of medium to large pet use, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a novel snap-fit ​​device for a pet running wheel, comprising two wheel bodies, four edge connectors and two central connectors. The wheel bodies are symmetrically provided with first annular protrusions on both sides of their surfaces, and each of the first annular protrusions has a first recess at its end. The wheel bodies are also provided with second annular protrusions on both sides of their surfaces, and a third annular protrusion is provided in the center of the wheel body, each of the third annular protrusions has a second recess at its end. The edge connectors are fitted into the surface of the first recess, and the central connectors are fitted into the surface of the second recess.

[0006] As a preferred embodiment, a first annular groove is formed on both sides of the inner wall of the wheel, and a second annular groove is formed in the middle of the inner wall of the wheel.

[0007] As a preferred embodiment, the surface of the first recessed portion is provided with a first through hole, and the surface of the second recessed portion is provided with a second through hole.

[0008] As a preferred embodiment, the first annular groove has a first fixing sleeve symmetrically arranged on its inner wall, and the second annular groove has a second fixing sleeve symmetrically arranged on its inner wall.

[0009] As a preferred embodiment, the inner wall of the edge connector is symmetrically provided with first screw holes, one end of the first screw holes passes through the inner wall of the first through hole and extends into the interior of the first fixing sleeve, and the first fixing sleeve is connected to the first screw holes by screws.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Reference Figures 1-4 This is the first embodiment of the present invention, which provides a novel snap-fit ​​device for a pet running wheel, including two wheel bodies 1, four edge connectors 9 and two central connectors 10. The wheel bodies 1 are symmetrically provided with first annular protrusions 2 on both sides of the surface, and each end of the first annular protrusions 2 is provided with a first recess 7. The wheel bodies 1 are also provided with second annular protrusions 3 on both sides of the surface, and a third annular protrusion 4 is provided in the middle of the wheel body 1. Each end of the third annular protrusion 4 is provided with a second recess 8. The edge connectors 9 are fitted into the surface of the first recess 7, and the central connectors 10 are fitted into the surface of the second recess 8.

[0023] A first annular groove 5 is provided on both sides of the inner wall of the wheel body 1, and a second annular groove 6 is provided in the middle of the inner wall of the wheel body 1.

[0024] A first annular groove 5 is provided on both sides of the inner wall of the wheel body 1, and a second annular groove 6 is provided in the middle of the inner wall of the wheel body 1.

[0025] The surface of the first recessed portion 7 is provided with a first through hole 71, and the surface of the second recessed portion 8 is provided with a second through hole 81;

[0026] The inner wall of the first annular groove 5 is symmetrically provided with a first fixing sleeve 51, and the inner wall of the second annular groove 6 is symmetrically provided with a second fixing sleeve 61.

[0027] The inner wall of the edge connector 9 is symmetrically provided with first screw hole rods 91. One end of the first screw hole rod 91 passes through the inner wall of the first through hole 71 and extends into the interior of the first fixing sleeve 51. The first fixing sleeve 51 is connected to the first screw hole rod 91 by screws.

[0028] The inner wall of the middle connector 10 is symmetrically provided with second screw hole rods 11. One end of the second screw hole rod 11 passes through the inner wall of the second through hole 81 and extends into the interior of the second fixing sleeve 61. The second fixing sleeve 61 is connected to the second screw hole rod 11 by screws.

[0029] Specifically, when assembling a pet running wheel, first align the two wheel bodies 1, then align the four edge connectors 9 one by one with the first recesses 7 on both sides of the surface of the two wheel bodies 1, so that the inner wall of the edge connector 9 fits against the surface of the first recesses 7, and then the first screw rod 91 passes through the first through hole 71 and extends into the inside of the first fixing sleeve 51. Then screws are screwed into the first fixing sleeve 51 from the inner wall of the wheel body 1, so that the first fixing sleeve 51 is connected and fixed to the first screw rod 91.

[0030] Then, the two central connecting pieces 10 are aligned with the second recesses 8 in the middle of the two wheel bodies 1, and the central connecting pieces 10 are fitted into the surface of the second recesses 8. The second screw rod 11 then passes through the second through hole 81 and extends into the interior of the second fixing sleeve 61. Then, the screw is screwed into the second fixing sleeve 61 from the inner wall of the wheel body 1, so that the second fixing sleeve 61 is connected and fixed to the second screw rod 11. Thus, the two wheel bodies 1 are aligned and spliced ​​together by the edge connecting piece 9 and the central connecting piece 10 to form a complete ring running wheel, which can rotate stably for pets to use.

[0031] This design uses the edge connector 9 to bear the lateral tension on both sides of the wheel body 1, and the middle connector 10 to reinforce the support in the middle of the wheel body 1. The overall load-bearing capacity is greatly improved, which can meet the daily activities of small pets and stably bear the weight and impact of movement of large pets, achieving adaptability to all types of pets. Through the combination of edge connector 9, middle connector 10 and screw fixing, the safety hazard of "the buckle easily coming off when using large pets" is fundamentally solved, and the product life is longer.

[0032] Reference Figures 1-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the surface of the wheel body 1 is provided with a plurality of grooves 12, which are distributed in a circular pattern.

[0033] Specifically, by creating grooves 12 on the surface of the wheel body 1, the amount of material used can be reduced without reducing the overall strength of the wheel body 1, thus achieving lightweighting and making the running wheel rotate more flexibly.
