[0002] A caster is a rotating device installed at the bottom of equipment, vehicles or furniture, used to provide support and convenient mobility. They are usually composed of tires, bearings, brackets and connectors, etc. However, existing casters may scratch the bottom plate during use, and when the furniture load is too high, the caster parts will deform, resulting in caster damage. Therefore, an anti-scratch and anti-deformation caster is needed.

Detailed implementation manners

[0025] Please refer to Figures 1-7 , the present utility model provides a technical solution: an anti-scratch and anti-deformation caster, including a mounting plate 1 and a caster mechanism 2, and the caster mechanism 2 is arranged at the lower end of the mounting plate 1;

[0026] The caster mechanism 2 includes a main shock absorber 21, a secondary shock absorber 22, a rotating member 23, a connecting plate 24, a protective member 25 and a rolling member 26. The main shock absorber 21 is fixedly connected to the lower end of the mounting plate 1, the secondary shock absorber 22 is arranged outside the main shock absorber 21, the rotating member 23 is installed at the lower end of the main shock absorber 21, the connecting plate 24 is arranged outside the rotating member 23, the protective member 25 is installed outside the connecting plate 24, and the rolling member 26 is installed inside the connecting plate 24.

[0027] As a further implementation of the above technical solution: as Figure 3 shown in Figure 6 , the main shock absorber 21 includes a limiting block 211 and a spring 212. The limiting block 211 is welded to the lower surface of the mounting plate 1, and the spring 212 is installed at the lower end of the limiting block 211. The limiting block 211 plays a positioning role during installation, and at the same time, during use, the cooperation of the spring 212 and the limiting block 211 enables the device to have a better shock absorption effect.

[0028] As a further implementation of the above technical solution: as Figure 3 shown in Figure 6As shown in the figure, the secondary shock absorber 22 includes an elastic telescopic rod 221 and a mounting seat 222. The lower end of the mounting plate 1 is fixedly connected to the elastic telescopic rod 221, and the lower end of the elastic telescopic rod 221 is fixedly connected to the mounting seat 222. The limiting block 211 and the mounting seat 222 form an elastic structure through the spring 212. The elastic telescopic rod 221 connects the mounting plate 1 and the mounting seat 222 together, enabling the device to have a certain shock absorption effect and preventing the internal parts from deforming due to the vibration of the device.

[0029] As a further implementation of the above technical solution: As Figure 4 shown in Figure 5 the figure, the rotating member 23 includes a connecting shaft 231, a clamping block 232, a main fixed bearing 233, and a connecting block 234. The lower end of the mounting seat 222 is fixedly connected to the connecting shaft 231. Clamping blocks 232 are fixedly connected to both the upper and lower ends of the connecting shaft 231. A main fixed bearing 233 is installed on the outer side of the connecting shaft 231, and a connecting block 234 is installed on the outer side of the main fixed bearing 233. Moreover, the outer diameter dimension of the connecting shaft 231 matches the inner diameter dimension of the main fixed bearing 233. When forces in different directions are applied to the device, the rolling member 26 will rotate following the direction of the applied force and roll forward. The clamping block 232 can prevent the connecting shaft 231 from disengaging from the main fixed bearing 233.

[0030] As a further implementation of the above technical solution: As Figure 3 shown in Figure 4 the figure, the connecting plate 24 is V-shaped, and the material of the connecting plate 24 is titanium alloy. The V-shaped connecting plate 24 can evenly transmit the received force to the connecting shaft 231. Titanium alloy has high strength and rigidity, can withstand large loads and pressures, prolong the service life of the device, and is not prone to deformation.

[0031] As a further implementation of the above technical solution: As Figure 2 shown in the figure, the protective member 25 includes a fixed block 251, a main protection plate 252, and a secondary protection plate 253. The fixed block 251 is welded to the outer side of the connecting plate 24, the main protection plate 252 is fixedly connected to the outer side of the fixed block 251, and the secondary protection plate 253 is welded to the upper end of the main protection plate 252. Through the setting of the protective member 25, it is prevented that foreign objects enter the inside of the connecting plate 24 and cause the foreign objects to jam the rolling member 26, making the device unable to roll.

[0032] As a further implementation of the above technical solution: As Figure 3As shown, the rolling element 26 includes a rotating shaft 261, a secondary fixed bearing 262, a roller 263 and a rubber sleeve 264. The rotating shaft 261 is bolted to the inner side of the connecting plate 24. The secondary fixed bearing 262 is fixedly connected to the outer side of the rotating shaft 261. The roller 263 is installed on the outer side of the secondary fixed bearing 262. The rubber sleeve 264 is clamped to the outer side of the roller 263. The rubber sleeve 264 prevents the device from scratching the ground during use and is easy to replace. The rotating shaft 261 is made of titanium alloy, enabling the rotating shaft 261 to withstand large loads and pressures.

[0033] Working principle: First, move an anti-scratch and anti-deformation caster to the working position. In the first step, when using the device, install the device at the bottom of the equipment. In the second step, when the staff places items inside the equipment, during the placement process, the device will be subjected to a downward pressure. At the moment of placement, the pressure on the device is relatively large, and then the pressure will decrease. In the third step, at the moment when the pressure is the largest, the cooperation of the main shock absorber 21 and the secondary shock absorber 22 will weaken a part of the pressure, making the pressure on the device smaller and preventing the internal parts from deforming due to excessive pressure. In the fourth step, when the device moves with the equipment at different heights, due to the gravity of the equipment and the device itself, the device will be subjected to a large impact force. The cooperation of the main shock absorber 21 and the secondary shock absorber 22 converts the impact force into vibrations between the equipment and the device, preventing the internal parts of the device from deforming due to the impact force. In the fifth step, when the device moves, the connecting plate 24 evenly transmits the pressure received to the rotating shaft 261, and the rotating shaft 261 then transmits the pressure to the roller 263. Subsequently, the roller 263 transmits the pressure to the ground through the rubber sleeve 264. The rubber sleeve 264 prevents the device from scratching the ground due to excessive pressure during the movement process. In this way, the use process of an anti-scratch and anti-deformation caster is completed.
