[0002] After searching, Chinese patent CN220298220U discloses a highly wear-resistant, pressure-resistant and silent universal wheel, comprising a mounting plate, a plurality of mounting holes are opened on the mounting plate, a bearing seat is fixedly connected to the side of the mounting plate, a rotating cylinder is rotatably connected to the bearing seat, a connecting column is slidably connected to the inside of the rotating cylinder, the connecting column passes through one end of the rotating cylinder and is fixedly connected to a mounting frame, a roller is rotatably connected to the mounting frame, and the utility model provides a first compression spring, a second compression spring and a third compression spring, so that when the roller is subjected to vibration impact, the vibration can be reduced in turn, thereby achieving the purpose of protecting luggage and bags and avoiding damage to fragile items in the luggage and bags; when the shock-absorbing property of the universal wheel is weakened, the adjusting screw is rotated to adjust the initial elastic force of the first compression spring, the second compression spring and the third compression spring, thereby improving the shock-absorbing effect of the universal wheel and increasing the service life of the universal wheel.

[0003] As mentioned above, most of the current highly wear-resistant, pressure-resistant and silent universal wheels adopt a shock-absorbing structure to reduce the vibration impact on the roller, so as to increase the service life of the universal wheel. At the same time, the shock-absorbing design can reduce the noise of the universal wheel to a certain extent. However, in actual applications, the main reason for the noise generated by the universal wheel is the friction between the roller and the bracket. The shock-absorbing design alone cannot achieve a significant noise reduction effect. For this reason, the applicant has designed a highly wear-resistant, pressure-resistant and silent universal wheel to solve the above problems. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-5 The utility model provides a technical solution: a highly wear-resistant, pressure-resistant and silent universal wheel, comprising a mounting plate 100 and a bracket 300 rotatably assembled under the mounting plate 100 through a riveted rod 200, a wheel set 400 is assembled in the bracket 300, the wheel set 400 comprises a roller 410 and a bolt 420 for mounting the roller 410 on the bracket 300, a liner 430 is coaxially embedded in the interior of the roller 410, the exterior of the bolt 420 is rotatably connected to the liner 430 through a bearing 440, and further comprises two baffles 450 which are symmetrically distributed and coaxially cover both sides of the roller 410 respectively, the inner sides of the two baffles 450 are coaxially embedded with inner liner gaskets 4510 covering the outside of the liner 430, the outer sides of the two baffles 450 are coaxially embedded with outer liner rings 4520, the outer ends of the outer liner rings 4520 extend to the outside of the baffles 450 and contact the inner wall of the bracket 300.

[0029] Based on the above structural setting, the highly wear-resistant, pressure-resistant and silent universal wheel is composed of a mounting plate 100, a riveted rod 200, a bracket 300 and a wheel set 400, wherein the mounting plate 100 is used for positioning and assembling the universal wheel, the riveted rod 200 realizes the rotational connection between the bracket 300 and the mounting plate 100, and the bracket 300 provides structural support for the rotational installation of the wheel set 400. Specifically, during use, the bushing 430 is rotatably mounted on the bolt 420 through the bearing 440, the roller 410 is sleeved on the outside of the bushing 430, and the two baffles 450 are coaxially covered on both sides of the roller 410, and the above five, namely the bushing 430, the roller 410, the bolt 420 and the two baffles 450, constitute the wheel set 400 assembled at the bottom of the bracket 300. During the rotation of the wheel set 400, due to the covering of the baffle 450 The liner 430 will not contact the bracket 300, and thus no noise will be generated. At the same time, due to the arrangement of the inner liner gasket 4510 and the outer liner ring 4520, the baffle plate 450 will not contact the liner 430 and the bracket 300, and thus no noise will be generated, thereby achieving a significant noise reduction effect. The highly wear-resistant, pressure-resistant and silent universal wheel optimizes the traditional caster structure and coaxially covers two baffle plates 450 on both sides of the roller 410. On the one hand, it can provide effective protection for the roller 410 and at the same time enhance the stability of the roller 410. On the other hand, the inner liner gasket 4510 and the outer liner ring 4520 respectively arranged on the inner and outer sides of the baffle plate 450 can effectively isolate the contact between the bracket 300 and the liner 430, and also isolate the contact between the baffle plate 450 and the liner 430 and the bracket 300, thereby significantly improving the noise reduction effect.

[0030] Furthermore, the roller 410 is provided with a plurality of hollow holes 460, all of which are fan-shaped structures, and the plurality of hollow holes 460 are distributed in a ring array. The roller 410 is the outer edge of the wheel set 400, and can be made of elastic materials such as polyurethane, rubber, and artificial rubber, which can absorb the vibration force generated by the collision between the roller 410 and the ground, thereby reducing noise, and the design of the hollow hole 460 structure further improves the shock absorption performance of the roller 410.

[0031] Furthermore, it also includes a plurality of pads 500 arranged between the mounting plate 100 and the bracket 300, and the plurality of pads 500 are distributed in a circular array. The pads 500 are arranged between the mounting plate 100 and the bracket 300 to reduce the noise generated between the mounting plate 100 and the bracket 300, and the pads 500 can effectively reduce the transmission of vibration and noise between the mounting plate 100 and the bracket 300.

[0032] Furthermore, a protrusion 110 is provided at the bottom of the mounting plate 100, and a plurality of T-slots 120 are provided on the protrusion 110 for inserting the cushion block 500. Preferably, by providing a plurality of T-slots 120 distributed in an annular array on the protrusion 110, it is helpful to quickly disassemble and assemble the cushion block 500, and the operation is convenient.

[0033] Furthermore, it also includes a cover 140 fixedly disposed on the outside of the protrusion 110 by means of screws 130, and a plurality of limiting holes 150 are provided on the cover 140 for the pad 500 to pass through. The cover 140 is disposed on the outside of the protrusion 110, and the plurality of limiting holes 150 can be used to position the installation of the pad 500, thereby ensuring that the pad 500 is securely and firmly installed on the protrusion 110.
