Description

Technical Field

[0001] This utility model relates to the field of foam roller technology, and in particular to a PU foam roller. Background Technology

[0002] Foamed wheels are wheels made of foamed plastic material through injection molding. They are characterized by dimensional stability, shrinkage rate of less than 1%, stable chemical composition, corrosion resistance, aging resistance, and good wear resistance. In particular, they are resistant to organic solvents, strong acids, and weak alkalis. Foamed wheels have a wide range of applications, especially in the fields of automobiles, airplanes, and various transportation equipment.

[0003] An existing patent (publication number: CN222451858U) discloses that "This utility model relates to the field of tire manufacturing technology, specifically to a foamed PU tire. The solution of this application forms a raised protective layer by setting protective protrusions on both sides of the tire body. When the tire encounters a sharp object during operation, it will first come into contact with the protective protrusions, preventing the sharp object from directly scratching the sidewall of the tire body. The protective protrusions are made of a material with good toughness, which can absorb and disperse the impact force from sharp objects, further improving the protective effect. This effectively solves the problem that the sidewalls of existing solid tires are easily scratched by sharp objects, and helps to extend the tire's service life."

[0004] In the process of developing this application, the inventors discovered the following problems with the prior art: the protective ridge strip in the PU foam tire is integrally molded with the tire body. Although the protective ridge strip can completely surround the side of the tire to form an effective protective layer and can absorb and disperse the impact force from sharp objects to a certain extent, once the protective ridge strip is damaged, the entire roller must be replaced, which not only increases the cost but also wastes resources.

[0005] Therefore, those skilled in the art have provided a PU foam roller to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a PU foam roller with a detachable protective mechanism. When the protective wheel cover is damaged, only the damaged part needs to be replaced, without replacing the entire roller, thus reducing maintenance costs.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A PU foam roller includes a hub, with protective mechanisms provided on both sides of the hub. Each of the two protective mechanisms includes a protective wheel cover. Each of the two protective wheel covers has a locking block fixedly provided on the opposite side. The hub has a locking groove on both sides, and the two locking blocks are respectively locked inside the locking groove.

[0009] A reinforcing ring is fixedly provided on the outer surface of the hub, and multiple fixing holes are provided inside the reinforcing ring. A roller body is fixedly provided on the outer surface of the hub.

[0010] Furthermore, multiple mounting holes are provided on one side of the wheel hub, and multiple fixing blocks are fixedly installed inside the wheel hub.

[0011] Furthermore, the roller body is fixedly provided with anti-slip texture.

[0012] Furthermore, both of the aforementioned card blocks are made of rubber.

[0013] Furthermore, both of the aforementioned protective wheel covers are made of nylon.

[0014] Furthermore, the two protective wheel covers are disposed on opposite sides of the roller body.

[0015] Furthermore, the roller body is fixedly installed inside multiple fixing holes.

[0016] This utility model has the following beneficial effects:

[0017] This utility model proposes a PU foam roller. When installing the protective mechanism, it is only necessary to align the locking block on one side of the protective wheel cover and insert it into the locking groove to complete the installation of the protective wheel cover. This allows the protective wheel cover to provide effective protection for both sides of the roller body and the hub. Moreover, the installation process is relatively simple and does not require complicated installation tools, thus improving installation efficiency. When the protective wheel cover is damaged and needs to be replaced, simply pull the protective wheel cover to move the locking block and disengage it from the locking groove, thereby achieving the replacement of the protective wheel cover. Not only is the operation simple, but it also eliminates the need to replace the entire roller, reducing maintenance costs and improving resource utilization. Attached Figure Description

[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 1-4 One embodiment provided by this utility model:

[0026] A PU foam roller includes a hub 6, with protective mechanisms 3 on both sides of the hub 6. Each of the two protective mechanisms 3 includes a protective wheel cover 302. Each of the two protective wheel covers 302 has a locking block 301 fixedly installed on the opposite side of each of the two protective wheel covers 302. Each of the two sides of the hub 6 has a slot 303. The two locking blocks 301 are respectively locked inside the slot 303.

[0027] A reinforcing ring 8 is fixedly provided on the outer surface of the hub 6, and multiple fixing holes 7 are provided inside the reinforcing ring 8. A roller body 1 is fixedly provided on the outer surface of the hub 6.

[0028] Multiple mounting holes 4 are provided on one side of the hub 6. Multiple fixing blocks 5 are fixedly installed inside the hub 6. Anti-slip texture 2 is fixedly installed on the outside of the roller body 1. Both locking blocks 301 are made of rubber. Both protective wheel covers 302 are made of nylon. The two protective wheel covers 302 are set on opposite sides of the roller body 1. Multiple fixing holes 7 are fixedly installed inside the roller body 1.

[0029] Specifically, when installing the protective mechanism 3, first align the locking block 301 on one side of the protective wheel cover 302 with the corresponding slot 303 on the outside of the wheel hub 6, and then smoothly insert it so that the locking block 301 is firmly locked into the slot 303. Next, install the other side of the protective wheel cover 302 in the same way. After installation, the two protective wheel covers 302 will be positioned on opposite sides of the roller body 1 and the wheel hub 6. The elastic combination of the nylon protective wheel cover 302 and the rubber locking block 301 can absorb impact energy, reduce the risk of roller damage due to collision, and ensure the long-term stable operation of the roller. Moreover, the simple and convenient snap-fit ​​installation method does not require complex tools, improving installation efficiency and reducing installation costs. After completing the installation of the protective mechanism 3, the roller can be securely installed onto the corresponding equipment through the multiple mounting holes 4 on one side of the wheel hub 6 using bolts or other suitable connectors. When the protective wheel cover 302 is... When the roller body 1 is scratched and its protection is compromised, the protective wheel cover 302 can be pulled to disengage the locking block 301 from the locking groove 303, facilitating replacement and saving costs. The reinforcing ring 8 fixed to the outer surface of the hub 6, and the multiple fixing holes 7 inside the reinforcing ring 8, are fixedly connected to the roller body 1, enhancing the firmness of the connection between the hub 6 and the roller body 1 and improving the overall structural strength of the roller, enabling it to withstand greater pressure and load. At the same time, the fixing block 5 inside the hub 6 further strengthens the structural stability of the hub 6, ensuring the reliability of the roller during operation and preventing the hub 6 from moving. The anti-slip texture 2 on the outside of the roller body 1 increases the friction between the roller and the surface of the object it contacts, allowing the roller to roll more stably during operation. Whether on a horizontal or sloping working surface, it can effectively prevent slippage, improving the safety and stability of the equipment operation.

[0030] Working principle: When installing the protective mechanism 3, align and insert the locking block 301 on one side of the protective wheel cover 302. The corresponding side of the wheel hub 6 has a locking groove 303. Lock the locking block 301 into the locking groove 303. Then, install the other side of the protective wheel cover 302 in the same way. After installation, the opposite side of the protective wheel cover 302 will be located on both sides of the roller body 1 and the wheel hub 6, playing a protective role. Then, through the multiple mounting holes 4 opened on one side of the wheel hub 6, use bolts or other connectors to install the roller onto the corresponding equipment. When the equipment drives the wheel hub 6 to rotate, the wheel hub 6 will synchronously drive the roller body 1 to rotate. The anti-slip texture 2 on the outside of the roller body 1 increases the friction when the roller moves relative to the surface of the contacting object, ensuring the stable rolling of the roller. During the operation of the roller, the protective wheel cover 302 can protect the roller body 1 and both sides of the wheel hub 6.

[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.
