The wheel body 2 is fixedly connected to the dustproof end cover 3 and the shaft frame 1 through the bolt assembly 4, and the wheel body 2 can rotate with the bolt assembly 4 as the central axis; the bolt assembly 4 includes bolts and nuts, and the threaded connection between the bolts and nuts facilitates the installation and disassembly of the wheel body 2 and the dustproof end cover 3; a falling path is formed between the end face of the wheel body 2 and the dustproof end cover 3; the impurities move along the falling path when they fall, so as to prevent the impurities from falling and affecting the rotation of the wheel body 2.

[0032] The dustproof end cover 3 is provided with a mounting groove 31, the bottom wall of which protrudes from the end surface of the wheel body 2; this can prevent impurities on the surface of the wheel body 2 from falling to the side of the wheel body 2 and accumulating during the rotation of the wheel body 2, thereby affecting the rotation of the wheel body 2.

[0033] In some embodiments, the end of the dustproof end cover 3 away from the wheel body 2 is a spherical surface, which can improve the smoothness of the surface of the dustproof end cover 3 and further reduce the possibility of debris such as lines and hair entering the wheel body 2.

[0034] The wheel body 2 includes a fixed wheel 21, a rotating wheel 22, a groove 23 and a tire 24; the fixed wheel 21 can be a bearing, and the fixed wheel 21 is provided with a rotating wheel 22, so that the rotating wheel 22 can rotate on the fixed wheel 21 when the fixed wheel 21 does not rotate, and the rotating wheel 22 is provided with a tire 24, through the friction between the tire 24 and the ground, the rotating wheel 22 is driven to rotate, thereby realizing the movement of the object on the universal wheel; grooves 23 are provided on both end surfaces of the rotating wheel 22, and dustproof end covers 3 are provided in the grooves 23 to prevent dust from entering the interior of the wheel body 2 and reduce the influence of dust accumulation on the wheel body 2; the groove 23 can be an annular groove to facilitate the fixed installation of the dustproof end cover 3; the dustproof end cover 3 protrudes from the groove 23; it can prevent lines and other debris on the tire 24 from falling to the connection between the fixed wheel 21 and the rotating wheel 22 during the rotation of the wheel body 2, thereby wrapping around the universal wheel and affecting the rotation of the universal wheel.

[0035] In some embodiments, a locking device 5 is provided on the shaft frame 1, which can limit the rotation of the rotating wheel 22, facilitate fixing the position of the universal wheel when needed, improve the flexibility and safety of use, and thus adjust the state of the universal wheel according to different needs and improve the scope of application. The locking device 5 can be existing technology, and the specific structure will not be repeated.

[0036] In some embodiments, the connecting plate 6 can be a long strip with four mounting holes 61 at the four corners, which can be fixedly connected to mobile equipment such as industrial carts. The mounting holes 61 can be waist-shaped holes, which can provide a larger adjustment space during the installation process, making the installation process more flexible.

[0037] In some embodiments, the mounting groove 31 is an arc groove facing away from the axle frame 1, and the shape of the other end of the wing plate 12 is adapted to the mounting groove 31. The thickness of the wing plate 12 may be smaller than the depth of the mounting groove 31. After the wing plate 12 and the mounting groove 31 are installed, the bottom wall of the mounting groove 31 has an upward supporting force on the wing plate 12, thereby improving the connection strength between the axle frame 1 and the wheel body 2, making the entire structure more stable, and improving the load-bearing capacity and durability of the universal wheel.

[0038] In some embodiments, a guide strip is provided on the top of the mounting groove 31, and the symmetry axis of the guide strip coincides with the symmetry axis of the rotation groove 31. The guide block is arc-shaped, and the length of the guide strip is greater than the width of the rotation groove 31. Impurities falling above the mounting groove 31 can be guided to both sides of the mounting groove 31, further improving the anti-winding performance. The cross-section of the guide strip can be U-shaped, which can support impurities falling above the mounting groove 31 and guide them to both sides of the mounting groove 31 under the action of the guide strip, thereby preventing impurities falling above the mounting groove 31 from entering the connection between the shaft frame 1 and the dustproof end cover 3 and affecting the rotation of the wheel body 2.

[0039] The specific working principle is as follows:

[0040] When in use, multiple universal wheels are installed on the mobile device through the connecting plate 6, and the position can be adjusted as needed; multiple universal wheels work together to carry the entire mobile device. When the mobile device is in use, the wheel body 2 rotates continuously. During the rotation of the wheel body 2, the dustproof end covers 3 at both ends of the wheel body 2 prevent dust from entering, thereby reducing the impact of dust accumulation on the wheel body 2; when impurities such as lines are adsorbed on the tire 24, the impurities will rotate with the tire 24. When the impurities fall, the impurities will fall along the two end surfaces of the wheel body 2. Since the dustproof end covers 3 protrude from the end surfaces of the wheel body 2, and the protruding end surfaces of the dustproof end covers 3 are spherical surfaces, when the impurities fall, the impurities will slide along the surface of the dustproof end covers 3. Due to the inertia when falling, when the impurities fall from the surface of the dustproof end covers 3, they will continue to move in the direction away from the wheel body 2, thereby preventing the impurities from falling to the connection between the fixed wheel 21 and the rotating wheel 22, thereby winding around the universal wheel and affecting the rotation of the universal wheel.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
