Abstract

The invention discloses a castor for furniture bottoms and relates to the field of furniture fittings. The castor comprises a connecting base, a support frame and a roller, the support frame is rotationally connected to the bottom of the connecting base through a first rotating shaft arranged along the vertical direction, the roller is connected to the support frame rotationally through a second rotating shaft arranged along the horizontal direction, a support seat is arranged on the support frame with the length in the vertical direction, a telescopic structure is arranged in the roller and comprises a connection layer, a cover layer and a plurality of telescopic rods, the telescopic rods connected with the connection layer and the cover layer can extend and retract radially, the connection layer is fixedly connected with the second rotating shaft, permanent magnets are arranged on one side, close to the telescopic rods, of the cover layer peripherally, electromagnets in mutual repulsion with the permanent magnets after being energized are arranged on one side, close to the telescopic rods, of the connection layer peripherally, and the cover layer is made of wearproof stretchable TPU material. Through the technical scheme, the problem that the support seat can only be moved with force larger than gravity of furniture when the support seat and the roller are switched is solved.

Description

technical field [0001] The invention relates to the field of furniture accessories, in particular to a caster for the bottom of furniture. Background technique [0002] The caster used for the bottom of the furniture includes a connection seat connected to the bottom of the furniture, a support frame that is rotatably connected below the connection seat through a first rotating shaft arranged in a vertical direction, and is rotatably connected to the support frame through a second rotating shaft arranged in a horizontal direction the scroll wheel. However, such casters have certain disadvantages: when the furniture moves to a certain designated position, it cannot be positioned, and the casters slide, and the furniture is easily moved under force. [0003] The patent application number is CN201410395309.5 discloses a caster, which includes a connecting seat, a support frame connected below the connecting seat through a first rotating shaft arranged in a vertical direction, ...
