CASTER WITH HORIZONTAL BRAKING

A caster with horizontal braking includes a connecting base, a wheel rotatably connected to the connecting base, and a brake assembly including a movable plate slidably connected to the connecting base and a rotary plate. The movable plate is provided with a brake pad at an end and a first abutting plate with a limiting portion thereon, and is rotatably connected to the connecting base. A second abutting plate fitted with the first abutting plate is arranged on the rotary plate. When the rotary plate is rotated to cause the second abutting plate to push the first abutting plate to move backward, the brake pad moves backward to abut against the wheel, one end of the second abutting plate is abutted against the limiting portion, the force applied by the wheel to the brake pad opposites the force applied by the second abutting plate to the limiting portion.
