Description

Technical Field

[0001] This utility model relates to the field of pet tools, and more particularly to a running wheel. Background Technology

[0002] As people's living standards improve, pet breeding has gradually come into the public eye, and hamsters are a popular small pet. They are known for their love of exercise, and in order to meet the exercise needs of hamsters, owners usually put a running wheel in the cage for them to use.

[0003] Currently available running wheels use bolt connections between the running wheel body and the running wheel connecting rod, which makes disassembly inconvenient and cleaning difficult.

[0004] Therefore, given the current state of the existing technology, developing a running wheel is an urgent problem to be solved. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a novel running wheel.

[0006] This solution provides a running wheel, including a running wheel body, which is connected to a running wheel connecting rod via a connecting part, and the connecting part can be quickly separated from the running wheel body.

[0007] Furthermore, the connecting part is connected to the running wheel body by magnetic attraction, and one end of the running wheel connecting rod is connected to the base.

[0008] Furthermore, the connecting part includes a first connecting part, which is hollow. A partition is provided in the middle of the first connecting part. Multiple grooves are provided on the inner wall of one end of the first connecting part. Magnetic material or material that can be attracted by magnetic material is placed inside the grooves. Multiple notches are provided on the outer surface of the first connecting part. Several bearings are provided inside the first connecting part. The bearings are connected to the connecting shaft. The connecting shaft is connected to the bolts on the fixed plate by bolts.

[0009] Furthermore, the running wheel body is bowl-shaped or a hollow column, with a protruding post in the middle of the running wheel body. The protruding post is hollow inside and is connected to one end of the connecting part.

[0010] Furthermore, the running wheel connecting rod is provided with a sliding groove, a retaining sleeve is fitted on the running wheel connecting rod, and a through hole is provided on the retaining sleeve, through which the connecting shaft passes.

[0011] Furthermore, the protruding post is provided with a baffle, one side of the protruding post is engaged with the connecting part two, one side of the connecting part two is provided with an inner ring, and the inner ring is provided with a plurality of grooves one, and magnetic material or material that can be attracted by magnetic material is placed inside the grooves one.

[0012] Furthermore, the base is equipped with a counterweight inside.

[0013] Furthermore, the inner wall of the running wheel body is corrugated.

[0014] Furthermore, the plurality of grooves on the second connecting part are arranged in a uniform circumferential array, and the diameter of the circumferential array of the grooves is the same as the diameter of the circumferential array of the grooves.

[0015] Furthermore, the first connecting part is connected to the first snap-fit ​​part through a notch, thereby restricting the axial rotation between the first connecting part and the running wheel body. The fixed disk is provided with a second snap-fit ​​part on one side, and the connecting shaft is connected to the second snap-fit ​​part through the second notch, thereby restricting the axial rotation between the connecting shaft and the fixed disk.

[0016] As can be seen from the above technical solutions, this utility model has the following advantages:

[0017] 1. The connecting part described in this utility model includes a first connecting part, which is hollow. A partition is provided in the middle of the first connecting part. Multiple grooves are provided on the inner wall of one end of the first connecting part. Magnetic material or material that can be attracted by magnetic material is placed inside the grooves. The magnetic material on the first connecting part and the magnetic material on the second connecting part attract each other. The two are separated by the partition. The partition is integrally injection molded with the running wheel body. Alternatively, the material attracted by the magnetic material on the first connecting part attracts the magnetic material on the second connecting part, or the magnetic material on the first connecting part attracts the material attracted by the magnetic material on the second connecting part. By adopting a magnetic attraction method, the running wheel body can be connected to the connecting part, and it can also be quickly separated by plugging and unplugging. It can be quickly disassembled and the running wheel body can be easily cleaned.

[0018] 2. In this utility model, the other end of the connecting shaft is connected to the bearing by an interference fit. The outer ring of the bearing is fitted into the second connecting part. The ferrule is fitted onto the running wheel body. The connecting shaft passes through the through hole on the ferrule and the sliding groove on the running wheel connecting rod, and is then connected to the bolt of the fixed plate. The notch on the connecting shaft and the snap-fit ​​part on the ferrule snap-fit ​​each other. Multiple sets of snap-fit ​​parts and notches are provided in pairs, so that the connecting shaft is stationary relative to the running wheel connecting rod. Thus, the second connecting part rotates axially relative to the connecting shaft through the bearing. The height of the running wheel body is connected by adjusting the tightness of the fixed plate and the connecting shaft, which solves the problem that the height of the running wheel body cannot be adjusted.

[0019] 3. In this utility model, the grooves of the connecting part 2 are evenly arranged in three places. When the connecting part 1 and the connecting part 2 are fixedly connected, the grooves overlap with the grooves of the connecting part 1. The permanent magnets fixed in the groove 801 and the permanent magnets fixed in the groove 1 attract each other. One hand holds the running wheel body, and the other hand rotates the connecting part 2 along the axial direction of the protrusion, so that the grooves of the connecting part 2 and the grooves of the connecting part 1 are offset. The attraction between the permanent magnets in the groove 1 and the permanent magnets in the groove is greatly reduced. Then the connecting part 2 can be easily removed, and the connecting part 1 can be easily removed from the protrusion. This solves the problem that the connecting part 1 needs a lot of force to separate from the protrusion. The above structure makes the connecting part 1 stably connected to the running wheel body, and when it needs to be disassembled and cleaned, the connecting part 1 can be easily separated from the running wheel body.

Detailed Implementation

[0035] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0036] Example 1: As Figure 1 As shown, this utility model provides a running wheel, including a running wheel body. The running wheel body is connected to a running wheel connecting rod through a connecting part. The connecting part and the running wheel body can be quickly separated. The connecting part is connected to the running wheel body by magnetic attraction.

[0037] like Figure 1 As shown, one end of the connecting part 11 is connected to the base 2.

[0038] like Figure 1-12As shown, the connecting part 11 includes a first connecting part 8, which is hollow. A partition 803 is provided in the middle of the first connecting part 8. Multiple grooves 801 are provided on the inner wall of one end of the first connecting part 8. Magnetic materials or materials that can be attracted by magnetic materials are placed inside the grooves 801. The magnetic materials on the first connecting part 8 and the second connecting part 9 are attracted to each other, and the two are separated by the partition 803. The partition 803 is integrally injection molded with the running wheel body 1. Alternatively, the materials attracted by magnetic materials on the first connecting part 8 and the magnetic materials on the second connecting part 9 are attracted to each other, or vice versa. By using magnetic attraction, the running wheel body 1 can be connected to the connecting part 11, and can also be quickly separated by plugging and unplugging, allowing for quick disassembly and convenient cleaning of the running wheel body 1.

[0039] like Figure 1-13 As shown: The outer surface of the connecting part 8 has multiple notches 802. The interior of the connecting part 8 contains several bearings 16, which are connected to the connecting shaft 17. Preferably, two bearings 16 are used, as two bearings provide greater stability. One end of the connecting shaft 17 is threadedly connected to a bolt (not shown in the figure). One end of the bolt is connected to the fixing plate 6 by adhesive bonding, and the other end of the bolt is threadedly connected to the connecting shaft 17. One end of the connecting shaft 17 has a threaded hole 21 (the thread line is not shown in the figure). The other end of the connecting shaft 17 is connected to the bearing 16 by an interference fit. The bearing 16 has an outer... The ring is inserted into the connecting part 2 9, the ferrule 7 is fitted onto the running wheel body 1, the connecting shaft 17 passes through the through hole 19 on the ferrule 7 and the slide groove 5 on the running wheel connecting rod 4, and is then connected to the bolt of the fixing plate 6. The notch 2 18 on the connecting shaft 17 and the snap-fit ​​part 20 on the ferrule 7 snap-fit ​​each other. Multiple sets of snap-fit ​​parts 20 and notches 2 18 are provided in pairs, so that the connecting shaft 17 is stationary relative to the running wheel connecting rod 4. Thus, the connecting part 2 9 rotates axially relative to the connecting shaft 17 through the bearing 16. The height of the running wheel body 1 is connected by adjusting the tightness of the fixing plate 6 and the connecting shaft 17, which solves the problem that the height of the running wheel body 1 cannot be adjusted.

[0040] like Figure 1-12 As shown, the running wheel body 1 is bowl-shaped, and a protruding post 10 is provided in the middle of the running wheel body 1. The protruding post 10 is hollow inside and is connected to one end of the connecting part 11.

[0041] like Figure 1-12 As shown, the running wheel connecting rod 4 is provided with a sliding groove 5, and a retaining sleeve 7 is fitted on the running wheel connecting rod 4. The retaining sleeve 7 is provided with a through hole 19. Preferably, the retaining sleeve 7 is composed of two parts that are snapped together.

[0042] like Figure 1-12As shown, the protruding post 10 is provided with a baffle 13. One side of the protruding post 10 is engaged with the connecting part 2 9. One side of the connecting part 2 9 is provided with an inner ring 902. The inner ring 902 has a plurality of grooves 1 901 inside. Magnetic material or material that can be attracted by magnetic material is placed inside the grooves 1 901. The outer diameter of the inner ring 902 is smaller than the inner diameter of the protruding post 10, so that the connecting part 2 9 can be engaged with the protruding post 10. The connecting part 2 9 can rotate around the axial direction of the protruding post 10.

[0043] Preferably, the grooves 901 of the connecting part 2 are evenly arranged in three positions, and the grooves 801 of the connecting part 18 are evenly arranged in three positions. When the connecting part 18 is fixedly connected to the connecting part 29, the grooves 801 and 901 overlap. The permanent magnets fixed in the grooves 801 and 901 attract each other. One hand holds the running wheel body 1, and the other hand rotates the connecting part 29 along the axis of the protrusion 10, so that the grooves 901 of the connecting part 29 and 801 of the connecting part 18 are offset. The attraction between the permanent magnets in the grooves 901 and 801 is greatly reduced. Then the connecting part 29 can be easily removed, and the connecting part 18 can be easily removed from the protrusion 10. This solves the problem that the connecting part 18 needs a lot of force to separate from the protrusion 10. The above structure makes the connecting part 18 stably connected to the running wheel body 1, and can be easily separated from the running wheel body 1 when it needs to be disassembled for cleaning.

[0044] The magnetic materials include magnets, metal alloy magnets, ferrite magnets (ceramic magnets), permanent magnets (such as neodymium iron boron magnets and ferrite magnets), and rare earth permanent magnet materials, which can adsorb other materials such as iron, cobalt, and nickel.

[0045] Materials that can be adsorbed by magnetic materials: such as iron, cobalt, and nickel.

[0046] like Figure 1-12 As shown, the base 2 is equipped with a counterweight 12 inside, which can improve the overall stability of the running wheel.

[0047] like Figure 1-12 As shown, the inner wall of the running wheel body 1 is corrugated. The corrugated inner wall is in direct contact with the small animal. By setting the corrugation, the friction can be improved. Preferably, the inner wall of the running wheel body 1 can also be made of frosted surface.

[0048] like Figure 1-12As shown, the connecting part 2 9 has a plurality of grooves 901 arranged in a uniform circumferential array, and the connecting part 1 8 has a plurality of grooves 801 arranged in a uniform circumferential array. The diameter of the circumferential array of grooves 901 is the same as the diameter of the circumferential array of grooves 801. The number of grooves 801 and grooves 901 is the same. Preferably, the number of grooves 801 and grooves 901 is 2-5, and more preferably, the number is 3.

[0049] like Figure 1-12 As shown, the connecting part 8 is connected to the snap-fit ​​part 14 through the notch 802. Multiple sets of notches 802 and snap-fit ​​parts 14 are arranged in pairs to restrict the axial rotation between the connecting part 8 and the running wheel body 1. A snap-fit ​​part 20 is provided on one side of the fixed disk 6. The connecting shaft 17 is connected to the snap-fit ​​part 20 through the notch 28. Multiple sets of notches 28 and snap-fit ​​parts 20 are arranged in pairs to restrict the axial rotation between the connecting shaft 17 and the fixed disk 6. With the above structural arrangement, the running wheel body 1 can rotate relative to the running wheel connecting rod 4. Preferably, the connecting part 9 is a polygonal column, and the hollow cavity of the protrusion 10 is also a corresponding polygonal cavity, so that the connecting part 9 can be directly snapped into the cavity of the protrusion 10, so that the connecting part 9 and the protrusion 10 can be snapped together without the notch 802 and snap-fit ​​part 14.

[0050] Bearing 16 is a silent bearing.

[0051] Example 2: The difference is that the protruding post 10 does not have a baffle 13, and the connecting part 2 9 and the connecting part 1 8 are in direct contact, thereby increasing the attraction between the two. This allows the size of the connecting part 1 8 to be designed to be smaller, solving the problem of insufficient attraction. Preferably, one of the grooves in the connecting part 2 9 and the connecting part 1 8 is provided with magnetic material, and the other is provided with material that is attracted by the magnetic material. Alternatively, both the grooves in the connecting part 2 9 and the connecting part 1 8 are provided with magnetic material.
