Description

Technical Field

[0001] This utility model relates to the field of children's integrated wheel technology, and in particular to a modular splicing children's integrated wheel. Background Technology

[0002] A one-piece wheel refers to a wheel assembly where the hub, rim, and spokes are cast from the same material using a mold to form a single, integrated structure. This design makes the hub, rim, and spokes an inseparable unit, thereby improving the stability and reliability of the wheelset.

[0003] In existing technology, children's strollers typically use one-piece wheels for movement. However, traditional one-piece wheels have a fixed structure, making it difficult to flexibly adjust and replace parts according to different needs. When a part of the wheel is damaged, the entire wheel often needs to be replaced, which not only increases the cost of use but also wastes resources.

[0004] In response to this technical problem, this application proposes a modular, interlocking, one-piece child wheel. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a modular, interlocking children's wheel. A limiting block, under the elastic force of a first spring, pops out and engages with a limiting groove on the inner wall of a first insert block, achieving initial splicing and fixing of the two rims. At this point, the first insert block can be further tightened to the rim using a first bolt. This allows for quick and stable assembly of the rim portion, avoiding the problem of inflexible adjustment inherent in traditional one-piece wheel structures.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A modular, interlocking children's integrated wheel includes a rim, spokes fixedly connected to the inner walls of both sides of the rim, connecting rings fixedly connected to the inner walls of the spokes, bearings provided on the inner walls of the connecting rings, first inserts fixedly connected to both sides of the inner walls of the rim, first slots formed in the inner walls of the rim, the first inserts corresponding to the first slots, pre-assembly components provided on both sides of the inner walls of the rim, the first inserts connected to the rim by first bolts, fixing components provided on both sides of the inner walls of the connecting rings, a valve guard fixedly connected to the inner wall of the right side of the rim, and protective components provided on both sides of the outer walls of the valve guard.

[0008] Furthermore, the pre-assembly assembly includes limiting blocks that are slidably connected on both sides of the inner wall of the wheel rim. One end of the inner side of the limiting block is arc-shaped, and the limiting block is connected to the inner wall of the wheel rim by a first spring.

[0009] Furthermore, one end of the first spring is connected to the limiting block, and the other end of the first spring is connected to the inner wall of the wheel rim.

[0010] Furthermore, a limiting groove is formed on the inner wall of the first insertion block, and the outer wall of the limiting block corresponds to the limiting groove.

[0011] Furthermore, the fixing component includes a second insert block fixedly connected to both sides of the inner wall of the connecting ring, and the second insert block is connected to the connecting ring by a second bolt.

[0012] Furthermore, the inner wall of the connecting ring is provided with a second slot, and the outer wall of the second insert block corresponds to the second slot.

[0013] Furthermore, the protective assembly includes slide rods fixedly connected to both sides of the outer wall of the valve protector, a top plate slidably connected to the outer wall of the slide rods, and the top plate and the outer wall of the valve protector are connected by a second spring.

[0014] Furthermore, one end of the second spring is connected to the top plate, and the other end of the second spring is connected to the outer wall of the valve guard.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the limiting block pops out under the elastic force of the first spring and is inserted into the limiting groove on the inner wall of the first insert block, thereby achieving the initial splicing and fixing of the two wheel rims. At this time, the first insert block and the wheel rim can be further tightened and connected by the first bolt, which can quickly and stably complete the assembly of the wheel rim part and avoid the problem of the traditional one-piece wheel structure being unable to be flexibly adjusted.

[0017] 2. In this utility model, for the valve guard on the right wheel rim, the top plate slidably connected to the slide rod on both sides of its outer wall can provide a certain degree of protection for the valve part under the elastic force of the second spring, preventing the collision of stones and the accumulation of dust.

[0024] 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.

[0025] Reference Figures 1-3 This utility model provides an embodiment of a modular, interlocking children's integrated wheel, including a rim 1, spokes 2 fixedly connected to the inner walls of both sides of the rim 1, connecting rings 3 fixedly connected to the inner walls of the spokes 2, bearings 4 disposed on the inner walls of the connecting rings 3, first inserts 5 fixedly connected to both sides of the inner walls of the rim 1, first slots 10 formed in the inner walls of the rim 1, the first inserts 5 corresponding to the first slots 10, and limiting blocks 6 slidably connected to both sides of the inner walls of the rim 1, one end of the limiting block 6 being arc-shaped, and the limiting blocks 6 being connected to the inner walls of the rim 1. The first spring 7 is connected to the first spring 7. One end of the first spring 7 is connected to the limiting block 6, and the other end of the first spring 7 is connected to the inner wall of the wheel rim 1. The inner wall of the first insert block 5 is provided with a limiting groove 8. The outer wall of the limiting block 6 corresponds to the limiting groove 8. The first insert block 5 and the wheel rim 1 are connected by the first bolt 9. The second insert block 11 is fixedly connected to both sides of the inner wall of the connecting ring 3. The second insert block 11 is connected to the connecting ring 3 by the second bolt 12. The inner wall of the connecting ring 3 is provided with a second slot 13. The outer wall of the second insert block 11 corresponds to the second slot 13.

[0026] Specifically, during the assembly of the two wheel rims 1, the first insert 5 on one wheel rim 1 is precisely aligned with the first slot 10 on the other wheel rim 1 and inserted. Upon insertion, the first insert 5 pushes the limiting block 6, causing the limiting block 6 to slide along the inner wall of the wheel rim 1 and compress the first spring 7. When the first insert 5 reaches the appropriate position, the limiting block 6 springs back under the elastic force of the first spring 7, locking into the limiting groove 8 on the inner wall of the first insert 5, thus initially fixing the two wheel rims 1. At this point, the first bolt 9 can be used to further tighten the connection between the first insert 5 and the wheel rim 1. Simultaneously, the second inserts 11 on both sides of the connecting ring 3 should also be inserted into the second slot 13 of the other connecting ring 3, and the second inserts 11 should be firmly fixed to the connecting ring 3 using the second bolt 12.

[0027] Reference Figure 1 , Figure 2 and Figure 4 A valve guard 14 is fixedly connected to the inner wall of the right wheel rim 1. A sliding rod 15 is fixedly connected to both sides of the outer wall of the valve guard 14. A top plate 16 is slidably connected to the outer wall of the sliding rod 15. The top plate 16 is connected to the outer wall of the valve guard 14 through a second spring 17. One end of the second spring 17 is connected to the top plate 16, and the other end of the second spring 17 is connected to the outer wall of the valve guard 14.

[0028] Specifically, the valve protector 14 on the right rim 1 has a top plate 16 slidably connected to the slide rods 15 on both sides of its outer wall. Under the elastic force of the second spring 17, this plate provides some protection to the valve area, preventing stone impacts and dust accumulation. One end of the second spring 17 is connected to the top plate 16, and the other end is connected to the outer wall of the valve protector 14. When the tire needs to be inflated, simply pull the top plate 16 upwards and compress the second spring 17 to expose the valve for easy operation. After inflation, the elastic force of the second spring 17 helps the top plate 16 automatically return to its original position.

[0029] Working principle: When two wheel rims 1 need to be spliced, the first insert 5 on one wheel rim 1 is aligned with the first slot 10 on the other wheel rim 1 and inserted. During the insertion process, the first insert 5 will squeeze the limiting block 6, causing the limiting block 6 to slide towards the inner wall of the wheel rim 1 and compress the first spring 7. When the first insert 5 is inserted into the appropriate position, the limiting block 6 pops out under the elastic force of the first spring 7 and is locked into the limiting groove 8 on the inner wall of the first insert 5, realizing the initial splicing and fixing of the two wheel rims 1. At this time, the first insert 5 and the wheel rim 1 can be further tightened and connected by the first bolt 9. At the same time, the second inserts 11 on both sides of the connecting ring 3 can be inserted into the second slot 13 of the other connecting ring 3, and the second inserts 11 are fixed to the connecting ring 3 by the second bolt 12.

[0030] For the valve protector 14 on the right rim 1, the top plate 16 slidably connected to the slide rods 15 on both sides of its outer wall can provide a certain degree of protection for the valve part under the elastic force of the second spring 17, preventing the collision of stones and the accumulation of dust. One end of the second spring 17 is connected to the top plate 16, and the other end is connected to the outer wall of the valve protector 14. When it is necessary to use the valve to inflate the tire, simply pull the top plate 16 upward and compress the second spring 17 to expose the valve for easy inflation. After inflation, the top plate 16 can be reset by the elastic force of the second spring 17.

[0031] 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.
