Description

Technical Field

[0001] This utility model relates to the technical field of casters, and in particular to a non-slip and wear-resistant caster structure. Background Technology

[0002] Casters are used to transport heavy objects, but casters are usually single wheels, so they are not easy to fix in place. This repeated movement can easily wear down the wheels. Utility Model Content

[0003] This invention aims to overcome the shortcomings of existing technologies, such as the inability to stop caster rotation and the tendency for wheels to wear out, by providing a non-slip and wear-resistant caster structure that can stop caster rotation when needed and reduce wheel wear.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A non-slip and wear-resistant caster structure includes: The swivel wheel serves as the main body of the caster. Two side plates are placed on the left and right sides of the rotating wheel, respectively; A top plate is placed above the rotating wheel, and the left and right sides of the top plate are respectively fixedly connected to two side plates; The main shaft has a T-shaped cross-section. The T-shaped horizontal section of the main shaft is placed on the outer side of one side plate, and the T-shaped vertical section of the main shaft passes through the center of the side plate and the wheel. The main shaft is rotatably connected to the wheel. A fixing nut is placed on the outer side of the other side plate. The fixing nut is threaded to the spindle, and the spindle is connected to the side plate through the fixing nut. A brake baffle is placed between two side plates. The cross-sectional shape of the brake baffle is V-shaped with the V-shaped opening facing the wheel. The lower end of the brake baffle is lower than the lower end face of the wheel. A rotating shaft is placed on the upper end of the brake baffle. The rotating shaft is fixedly connected to the upper end of the brake baffle. The rotating shaft is placed in front of the top plate. The two ends of the rotating shaft are rotatably connected to the sides of the two side plates respectively. Two clamping plates are placed on the left and right sides of the rotating wheel, respectively. One end of the clamping plate is fixedly connected to the brake baffle, and the other end of the clamping plate is placed between the rotating wheel and the side plate. One side of the clamping plate is in contact with the inner side of the side plate, and the other side of the clamping plate is in contact with the side of the rotating wheel. Several anti-slip grooves are evenly distributed on the outer surface of the wheel, and the anti-slip grooves are perpendicular to the two side plates.

[0005] During installation, place the caster wheel between the two side plates and secure it with the main shaft and fixing nuts. Then, fix the top plate to the bottom of the support plate with screws. When braking is needed, rotate the brake baffle downwards around the pivot axis so that the lower end of the brake baffle contacts the ground and the two locking plates engage between the caster wheel and the side plates to restrict the rotation of the caster wheel. This double braking reduces the rotation of the caster wheel. When braking is no longer needed, simply flip up the brake baffle. The anti-slip grooves on the caster wheel not only prevent slipping but also allow for clear observation of the wear level of the caster wheel, achieving the purpose of stopping the caster wheel rotation when needed and reducing wheel wear.

[0006] Preferably, the front end face of the top plate is provided with a groove, the cross-sectional shape of which is arc-shaped. The outer surface of the rotating shaft is provided with a retaining strip, the shape of which corresponds to the shape of the groove. The retaining strip is fixedly connected to the rotating shaft, and the groove lies along the movement path of the retaining strip rotating around the rotating shaft. The angle between the retaining strip and the brake baffle is 90°-180°. The brake baffle is engaged with the top plate through the cooperation of the retaining strip and the groove on the rotating shaft. The groove and retaining strip are designed so that when braking is not required, the brake baffle can be flipped upwards without falling off due to vibration or other reasons, thus affecting the rotation of the rotating wheel.

[0007] Preferably, a damping block is provided between the side plate and the rotating shaft. The damping block is fixedly connected to the inner side of the side plate and contacts the side of the rotating shaft. The damping block provides resistance to the movement of the rotating shaft, reducing the downward tilting of the brake baffle.

[0008] Preferably, a hollow shaft is provided at the center of the rotating wheel, and the rotating wheel is wrapped around the outer surface of the hollow shaft. The rotating wheel and the hollow shaft are fixedly connected. A spring is provided inside the hollow shaft. The T-shaped vertical section of the main shaft passes through the side plate and the hollow shaft and is placed on the outside of another side plate. The spring is wrapped around the main shaft, and its two ends are fixedly connected to the inner surface of the side plate. The hollow shaft prevents the main shaft from contacting the rotating wheel, reducing wear, and the spring increases the cushioning capacity of the rotating wheel's side surface.

[0009] Preferably, the outer surface of the rotating wheel is provided with a plurality of anti-slip strips, the anti-slip strips being perpendicular to the anti-slip grooves, the anti-slip strips being placed between two adjacent anti-slip grooves, and a plurality of anti-slip strips being placed between two anti-slip grooves. The anti-slip strips are evenly distributed on the outer surface of the rotating wheel and are fixedly connected to the outer surface of the rotating wheel. The anti-slip strips increase the anti-slip capability of the rotating wheel.

[0010] Preferably, the top plate has a plurality of mounting holes, which are evenly distributed on the top plate. The mounting holes facilitate fixing to the cargo plate with screws.

[0011] The beneficial effects of this utility model are: it can stop the caster from rotating when needed and reduce wheel wear; the slot and locking strip are designed so that when braking is not needed, the brake baffle can be flipped up and will not fall down due to vibration or other reasons, thus affecting the rotation of the caster; the damping block can provide resistance to the movement of the shaft and reduce the downward flipping of the brake baffle; the hollow shaft prevents the main shaft from contacting the caster and reduces wear; the spring can increase the cushioning capacity of the caster's side; the anti-slip strip increases the anti-slip capability of the caster; and the mounting holes facilitate fixing to the cargo plate with screws.

The brake baffle 6 is V-shaped with its opening facing the wheel 1, and its lower end is lower than the lower end face of the wheel 1. The rotating shaft 7 is placed on the upper end of the brake baffle 6 and is fixedly connected to the upper end of the brake baffle 6. The rotating shaft 7 is placed in front of the top plate 3, and its two ends are rotatably connected to the sides of the two side plates 2 respectively. Two clamping plates 8 are placed on the left and right sides of the wheel 1 respectively. One end of the clamping plate 8 is fixedly connected to the brake baffle 6, and the other end of the clamping plate 8 is placed between the wheel 1 and the side plate 2. One side of the clamping plate 8 is in contact with the inner side of the side plate 2, and the other side of the clamping plate 8 is in contact with the side of the wheel 1. Several anti-slip grooves 9 are evenly distributed on the outer surface of the wheel 1, and the anti-slip grooves 9 are perpendicular to the two side plates 2.

[0016] like Figure 6 As shown, a slot 10 is provided on the front end face of the top plate 3. The cross-sectional shape of the slot 10 is arc-shaped. A strip 11 is provided on the outer side of the rotating shaft 7. The shape of the strip 11 corresponds to the shape of the slot 10. The strip 11 is fixedly connected to the rotating shaft 7. The slot 10 is on the movement path of the strip 11 rotating around the rotating shaft 7. The angle between the strip 11 and the brake baffle 6 is 90°-180°. The brake baffle 6 is engaged with the top plate 3 through the cooperation of the strip 11 and the slot 10 on the rotating shaft 7.

[0017] like Figure 4 As shown, a damping block 12 is provided between the side plate 2 and the rotating shaft 7. The damping block 12 is fixedly connected to the inner side of the side plate 2 and the damping block 12 is in contact with the side of the rotating shaft 7.

The rotating wheel 1 is fixedly connected to the hollow shaft 13. A spring 14 is provided inside the hollow shaft 13. The T-shaped vertical section of the main shaft 4 passes through the side plate 2 and the hollow shaft 13 and is placed on the outside of another side plate 2. The spring 14 is surrounded around the main shaft 4. The two ends of the spring 14 are fixedly connected to the inner surface of the side plate 2 respectively.

[0019] like Figure 7As shown, a number of anti-slip strips 15 are provided on the outer side of the rotating wheel 1. The anti-slip strips 15 are perpendicular to the anti-slip grooves 9.

The damping block 12 prevents the shaft 7 from rotating too fast and also provides a double guarantee to prevent the brake baffle 6 from flipping down. The spring 14 can act as a buffer against the impact on the side of the caster wheel 1, achieving the purpose of stopping the caster wheel rotation when needed and reducing wheel wear.
