Definitions
- the present invention relates to a caster, and in particular, allows the caster to rotate more smoothly when it rotates 180 degrees reversely, and in particular to effectively support the weight of an object on the upper part, so that the product does not shake at all and the caster can It was invented to allow smooth reverse rotation.
- casters are a workbench. It is mounted on the lower end of relatively heavy products such as refrigerators and washing machines. In particular, when moving 180 degrees in the reverse direction while moving heavy products, a lot of strain occurs on the casters, resulting in damage to the casters when used for a long time.
- the overall configuration it is composed of a first panel 211, a second panel 213, a caster panel 221, and a caster body 223, and is formed of four units as a whole.
- the present invention is to solve the above problems
- the caster When the caster goes straight and turns at an angle to rotate, especially when it rotates 180 degrees in the opposite direction, it rotates more smoothly with less force and has multiple thrusts to handle the weight on the upper side of the caster. It was installed with ball bearings.
- the product on the upper side can be safely moved and the product can bear the weight of the product on the upper side, so the product's lifespan can be increased. there is.
- a center body, a connecting body, and a lower body are sequentially formed on the lower side of the support plate formed at the upper end, and in particular, a rotating body is mounted between the connecting body and the center body,
- six thrust ball bearings are installed between the support plate, the center body, the connecting body, the rotating body, and the lower body so that the caster goes straight and turns at any angle to rotate, especially when it rotates 180 degrees in reverse and moves in the opposite direction. It is made to rotate.
- a rotating body is added between the connecting body and the central body, a thrust ball bearing is additionally installed between the connecting body and the rotating body, and a thrust ball bearing is additionally installed between the rotating body and the central body.
- the upper and lower pillars formed on the center body are additionally installed so that the thrust ball bearing and the central axis of the wheel can easily get out of position, so that the caster rotates by turning or rotating 180 degrees in reverse. This is to solve the problem of a large crowd coming to the caster.
- the present invention can safely move the object on the upper side by reducing the vibration of the caster when the caster goes straight and then turns and rotates or reverses 180 degrees to move in the opposite direction, and can handle the weight on the upper side of the caster.
- 6 thrust ball bearings are installed between parts by additionally mounting a rotating body so that
- the upper and lower pillars formed in the center body, the thrust ball bearing, and the central axis of the wheel are improved so that they can easily deviate from a straight line, so that the caster can rotate more smoothly.
- Figure 2 is an overall longitudinal cross-sectional view of the present invention.
- Figure 3 is an embodiment in which the wheel, the upper pillar part, and the lower pillar part of the present invention are on a straight line.
- Figure 4 is a longitudinal cross-sectional view when the caster of the present invention is located in the opposite direction.
- Figure 5 is an embodiment in which the caster of the present invention is positioned in the opposite direction, the wheel, the upper column portion, and the lower column portion are on a straight line.
- the center body 3, the connecting body 4, and the lower body 5 are sequentially mounted on the lower side of the support plate 2 and the support plate 2 formed at the upper end of the caster 1,
- the center body 3 is composed of an upper pillar part 6 and a lower pillar part 7, but the upper pillar part 6 and the lower pillar part 7 are configured on a diagonal line,
- the thrust ball bearing 9 is mounted between the support plate 2 and the upper nut 8 so that the support plate 2 and the upper nut 8 can rotate freely.
- the lower body part 5 and the lower pillar part 7 are fixed using the lower nut 10, and the thrust ball bearing 11 is mounted between the lower body part 5 and the lower nut 10,
- a thrust ball bearing 12 is mounted between the outer upper surface of the lower body part 5 and the outer lower surface of the center body 3 so that the lower body part 5 and the center body 3 can rotate freely.
- the present invention allows the caster 1 to rotate more smoothly when reversely rotating at 180 degrees
- the rotating body 20 is mounted between the lower side of the coupling body 4 and the outer side of the center body 3, and the thrust ball bearing 21 is mounted between the coupling body 4 and the rotating body 20, and the rotating body 20 and the center body A thrust ball bearing 22 is mounted between (3).
- the caster 1 is composed of 5 units composed of the support plate 2, the central body 3, the connecting body 4, the rotating body 20, and the lower body 5, and the 5 units are divided into 6 units.
- Thrust ball bearings (9) (11) (12) (13) (21) (22) are interconnected.
- the caster 1 When the caster 1 rotates, it rotates more smoothly and by reducing the load generated during rotation, it can rotate smoothly with less force.
- FIGS. 3 and 5 represent the central axes of the parts
- A represents the central axis of the thrust ball bearing (13, 21)
- B represents the central axis of the upper column (5) and the thrust ball bearing (9, 22)
- C represents the lower column (7) and the thrust ball bearing (11) represents the central axis of (12)
- D represents the central axis of the wheel.
