[0027] An embodiment of this utility model provides a caster with an anti-tangling cover, such as... Figure 1-6 As shown, it includes:

[0028] The wheel frame 100 includes a top plate 110 and two support arms 120 respectively connected to the top plate 110.

[0029] The wheel body 200 is rotatably mounted between two support arms 120. The wheel body 200 has stepped grooves 210 on both sides near the two support arms 120.

[0030] The anti-tangle cover body 300 includes a cover part 310, which is rotatably connected to the stepped groove 210. The cover part 310 is provided with a first groove 320, which is engaged with the support arm 120. The cover part 310 covers the outer side of the lower end of the support arm 120.

[0031] The wheel frame 100 is the main structure of the caster, used to support the wheel body 200 and provide an installation interface. The wheel frame 100 includes a top plate 110 and two support arms 120. The top plate 110 is used to connect to external objects (such as furniture, equipment, etc.), and the support arms 120 are used to mount the wheel body 200. The wheel body 200 is used to realize the movement function. The wheel body 200 is rotatably mounted between the two support arms 120, and stepped grooves 210 are provided on both sides of the wheel body 200 near the support arms 120. The stepped grooves 210 are used to cooperate with the anti-entanglement cover body 300 to prevent debris from getting tangled in the wheel body 200 and affecting the normal use of the caster. The anti-entanglement cover body 300 is used to prevent debris from getting tangled in the wheel body 200. It includes a cover part 310, which is rotatably connected by cooperating with the stepped grooves 210 on the wheel body 200, and is engaged with the support arms 120 through a first groove 320, thereby fixing it to the wheel frame 100. By engaging the stepped groove 210 of the wheel body 200 with the anti-tangling cover body 300, the cover body 310 covers the outer side of the lower end of the support arm 120, effectively preventing debris (such as cables, strips of cloth, etc.) from tangling around the wheel body 200 and the wheel frame 100, thus avoiding the caster from getting stuck or damaged due to tangled debris. This utility model has a simple design, is easy to produce and install, and reduces manufacturing costs. The anti-tangling cover body 300 is fixed to the wheel frame 100 by a snap-fit ​​method, resulting in a stable structure that is not easily loosened.

[0032] In some embodiments, the wheel 200 is fixed to the support arm 120 by fasteners 220, and the inner wall of the first groove 320 is also provided with a second groove 330, which is used to avoid the fasteners 220.

[0033] Fasteners 220 (such as screws, bolts, etc.) are used to securely install the wheel body 200 onto the support arm 120, ensuring that the wheel body 200 will not loosen during use. The use of fasteners 220 improves the installation accuracy and stability of the wheel body 200, enabling it to better withstand loads and impacts. Fasteners 220 facilitate the installation and disassembly of the wheel body 200, making maintenance and replacement easier. The fasteners 220 can be installed by directly passing through the support arm 120 and the wheel body 200, or by using other auxiliary structures (such as nuts, washers, etc.). The inner wall of the first groove 320 also has a second groove 330, which is used to avoid interfering with the fasteners 220. When the anti-tangle cover body 300 is installed on the wheel body 200, the fasteners 220 may interfere with the anti-tangle cover body 300. By providing the second groove 330 on the inner wall of the first groove 320, the anti-tangle cover body 300 can be installed smoothly while avoiding collisions or interference with the fasteners 220. The design of the second groove 330 allows the anti-tangle cover body 300 to be installed on the wheel 200 more easily, without worrying about interference from the fastener 220. The recessed design allows for better fit between the anti-tangle cover body 300, the wheel 200, and the support arm 120, resulting in a cleaner overall appearance. This avoids damage caused by interference between the fastener 220 and the anti-tangle cover body 300, improving the overall lifespan and reliability of the caster.

[0034] In some embodiments, the cover portion 310 is further provided with a third groove 340, which is connected to the first groove 320, and the depth of the first groove 320 is greater than the depth of the third groove 340.

[0035] The third groove 340 connects with the first groove 320, forming a stepped groove structure. The depth of the first groove 320 is greater than the depth of the third groove 340. The third groove 340 increases the contact area and mating depth between the cover body 310 and the wheel body 200, thereby improving the overall stability of the anti-tangling cover body 300. When the wheel body 200 vibrates or is impacted during movement, the deeper first groove 320 and the shallower third groove 340 work together to reduce the risk of the anti-tangling cover body 300 loosening or falling off. The first groove 320 is mainly used for engaging with the support arm 120, while the third groove 340 further optimizes this engaging effect. Through the groove design of different depths, more precise positioning and mating can be achieved, ensuring that the anti-tangling cover body 300 fits tightly against the wheel body 200 and the support arm 120 after installation, preventing debris from entering. The stepped structure design of the third groove 340 and the first groove 320 not only optimizes the function, but also makes the overall structure more compact and reasonable, and improves the appearance and craftsmanship of the product.

[0036] In some embodiments, the lower inner wall of the first groove 320 is arc-shaped.

[0037] The lower inner wall of the first groove 320 is arc-shaped. In some embodiments, its two side walls are straight, i.e., its cross-sectional shape resembles the letter "U". This shape, with two side walls and a bottom, provides good support and positioning. The depth of the U-shaped groove is greater than the depth of the third groove 340, which allows the first groove 320 to fit more tightly with the support arm 120, while providing sufficient space for the third groove 340 to accommodate support arms 120 of different sizes. The U-shaped groove design makes the installation and removal of the anti-tangle cover body 300 more convenient. Users only need to align the anti-tangle cover body 300 with the support arm 120 and press it gently to achieve a snap-fit, without complicated tools or operations. During removal, simply pry the sides of the anti-tangle cover body 300 gently to easily remove it from the support arm 120 for easy cleaning and maintenance. The U-shaped groove design not only has functional advantages but also makes the overall appearance of the anti-tangle cover body 300 more concise and aesthetically pleasing. This design conforms to the concept of modern industrial design and enhances the overall quality of the product.

[0038] Furthermore, the third groove 340 is arc-shaped.

[0039] The third groove 340 is arc-shaped, meaning its cross-section is a circular arc. The third groove 340 is connected to the first groove 320, but its depth is less than that of the first groove 320, forming a stepped structure. The arc-shaped design makes the third groove 340 more gentle when in contact with the wheel 200 or other components.

[0040] The smooth curve of the arc-shaped groove can effectively disperse stress and avoid stress concentration caused by sharp edges or straight transitions.

[0041] In some embodiments, the support arm 120 is provided with a snap-fit ​​groove 121, and the first groove 320 is provided with a buckle 321 that engages with the snap-fit ​​groove 121.

[0042] A snap-fit ​​groove 121 is provided on the support arm 120 for engaging with a snap fastener 321 on the anti-tangle cap body 300. This design allows the anti-tangle cap body 300 to be securely fixed to the support arm 120. The snap fastener 321 is provided on the first groove 320 of the anti-tangle cap body 300, matching the snap-fit ​​groove 121 on the support arm 120. The snap fastener 321 typically has a certain degree of elasticity, allowing it to easily snap into the snap-fit ​​groove 121 during installation and remain stable during use. The engagement of the snap fastener 321 with the snap-fit ​​groove 121 ensures that the anti-tangle cap body 300 will not loosen or fall off during use. This design provides additional fixing force, preventing the anti-tangle cap body 300 from shifting due to vibration or impact. The elastic design of the snap fastener 321 can accommodate a certain amount of installation error, ensuring a reliable connection under different conditions. The snap fastener 321 design makes the installation and removal of the anti-tangle cap body 300 more convenient. Users simply align the anti-tangle cover body 300 with the snap-fit ​​slot 121 on the support arm 120 and press gently to complete the installation. For disassembly, simply pry the snap fastener 321 to remove the anti-tangle cover body 300 from the support arm 120; no complicated tools are required. The design of the snap fastener 321 and snap-fit ​​slot 121 not only offers functional advantages but also makes the overall appearance of the anti-tangle cover body 300 more concise and aesthetically pleasing. This design aligns with modern industrial design principles and enhances the overall quality of the product.

[0043] Furthermore, three snap-fit ​​slots 121 are provided, two of which are respectively located on both sides of the center line of the support arm 120, and the other snap-fit ​​slot 121 is located on the center line of the support arm 120 and its position is higher than the two snap-fit ​​slots 121.

[0044] Three locking slots 121 are provided, and this multi-point locking design provides a more stable connection. Two locking slots 121 are respectively located on both sides of the center line of the support arm 120. This symmetrical layout ensures that the anti-tangle cap body 300 is evenly stressed on both sides, reducing tilting or loosening caused by unilateral stress. The third locking slot 121 is located on the center line of the support arm 120, and its position is higher than the two locking slots 121 on both sides. This design forms a triangular support structure, further enhancing the stability of the anti-tangle cap body 300. The design of the three locking slots 121 forms a stable triangular support structure, which can effectively prevent the anti-tangle cap body 300 from loosening or falling off during use. By setting a higher locking slot 121 on the center line of the support arm 120, the vertical displacement of the anti-tangle cap body 300 can be further restricted, ensuring its position on the wheel 200 is more stable.
