Abstract

The utility model discloses a movable castor, which belongs to the technical field of casters, wherein the protruding distance of the tail end of a first clamping block far away from the axis of a rotation stopping piece is smaller, so that the tail end of the first clamping block far away from the axis of the rotation stopping piece is prevented from blocking the movement of a second clamping block, and the first braking part can smoothly rotate along a first rotation direction; the second clamping block is propped against any one of the first clamping blocks, and in the process of upward movement of the second clamping block, the second clamping block can slide along the first clamping block which is obliquely arranged, so that the first clamping block is helped to be guided to drive the rotation stopping piece to rotate, the first clamping block is staggered with the second clamping block, and the second clamping block is further smoothly inserted between two adjacent first clamping blocks, and the rotation stopping piece and the rotating shaft are braked; therefore, by adopting the movable caster, the way of braking the rotation stopping piece and the rotating shaft by the first braking part is smoother, and the braking operation of the movable caster is more convenient.

Description

Movable castor Technical Field The utility model relates to the technical field of casters, in particular to a movable caster. Background The movable castor is configured to rotate about a vertical axis and may be mounted to the bottom of an implement such as a trolley, rollator, or medical equipment cart to facilitate movement of the implement. At present, a braking device of a movable castor can generally stop the rotation of a roller and the universal rotation of the whole castor at the same time, and the braking device stops the universal rotation of the castor in a mode that a braking part compresses or clamps a rotating shaft. However, the conventional braking portion does not perform smooth braking operation of the rotating shaft, and a user needs to repeatedly operate the rotating shaft several times to brake the rotating shaft successfully, so that the braking operation of the movable caster is inconvenient. Disclosure of utility model The present utility model aims to solve at least one of the technical problems existing in the prior art. Therefore, the movable castor is provided with the first braking part for braking the rotation stopping piece and the rotating shaft, so that the braking operation of the movable castor is more convenient. According to an embodiment of the present utility model, a movable caster comprises: The mounting seat is provided with an up-down through shaft hole; The rotating shaft is rotatably arranged in the shaft hole; the rotation stopping piece is connected with the bottom of the rotating shaft, a plurality of first clamping blocks are arranged at the bottom of the rotation stopping piece and are distributed at intervals around the rotating axis of the rotation stopping piece, and the downward protruding distance of each first clamping block is gradually reduced outwards along the radial direction of the rotation stopping piece; the roller is hinged with the mounting seat; The locking piece is hinged with the mounting seat and is provided with a first braking part and a second braking part, the first braking part is positioned below the rotation stopping piece, the top of the first braking part is provided with a second clamping block, and the second braking part is positioned above the roller; The locking piece rotates along a first rotation direction to enable the second clamping block to be inserted between any two adjacent first clamping blocks, the second braking portion abuts against the roller, and the locking piece rotates along a second rotation direction to enable the second clamping block to be separated from the rotation locking piece, and the second braking portion is separated from the roller.
