The invention relates to a mechanical accessory, in particular to a castor. The invention relates to a quick-dismantling type castor for a wheel, which comprises a fork and a wheel, wherein the center of the wheel is provided with a wheel shaft; according to the invention, the foot fork and the wheel shaft are designed to be matched with each other to form a clamping structure, so that the foot fork and the wheel can be quickly assembled and disassembled; meanwhile, the dust cover with the pocket-shaped cavity structure is designed, so that the wheels can be prevented from being wound by foreign matters, and the joint of the wheel shaft and the foot fork can be prevented from being wound by the foreign matters. The caster wheel can well prevent the caster wheel from being wound by the foreign matters, and can quickly separate the wheel from the fork even if the foreign matters are wound, so that the wound foreign matters can be cleaned conveniently, and the service life of the caster wheel is prolonged.
Description
Technical Field
The invention relates to a mechanical accessory, in particular to a castor.
Background
The caster is a common mechanical accessory which is arranged at the bottom of the appliance to ensure that the appliance is convenient and flexible to move, and is widely applied to the fields of hand and foot frames, shelves, instruments, mechanical equipment, furniture and the like. The wheels of the casters in the market are generally riveted with the foot forks through transverse shafts or are connected with the foot forks through bolts, and when the casters are used on seats of barbershops, hair cut off on the ground can be easily wound on the wheels and the joints of the wheels and the foot forks; because the truckle of above-mentioned structure can't realize quick assembly disassembly in the use, can't separate wheel and fork and equipment promptly, therefore winding hair is difficult to clear up, has seriously influenced the normal use of truckle.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide the wheel quick-dismantling type castor which can quickly separate and assemble the wheel and the foot fork and is convenient for cleaning windings.
In order to achieve the aim, the quick-dismantling type wheel caster comprises a fork and wheels, wherein the center of each wheel is provided with a wheel shaft, and two ends of each wheel shaft are in a circular clamping groove structure; the two sides of the wheel are respectively provided with a left dust cover and a right dust cover, and the dust covers comprise a bottom plate and pocket-shaped opening cavities arranged on the bottom plate; the bottom plate of the dustproof cover is provided with a through hole through which the wheel axle can pass, two ends of the wheel axle respectively pass through the through holes on the left dustproof cover and the right dustproof cover, and the annular clamping groove structures at the two ends are arranged in the pocket-shaped cavity of the dustproof cover; the foot fork is inserted into the pocket-shaped cavity of the dust cover, and the opening directions of the pocket-shaped cavities of the left dust cover and the right dust cover are respectively consistent with the insertion directions of the foot fork at the left side and the right side; the lower ends of the two side foot forks are in inverted U-shaped bayonet structures, and the bayonet structures are matched with annular clamping groove structures at two ends of the wheel shaft; the bayonet spring piece is riveted at the foot fork clamping opening structure, a riveting hole is formed in the upper end of the bayonet spring piece and riveted with the foot fork, the lower end of the bayonet spring piece is of an opening structure, the lower ends of two sides of the opening structure of the bayonet spring piece extend inwards to form two lug structures, and the lug structures are attached to the sides of the clamping opening structure at the lower end of the foot fork.
Preferably, the bottom plate of the dust cover is a round bottom plate, and a plurality of reinforcing ribs are arranged on the surface of the bottom plate at the inner side of the pocket-shaped cavity.
When the wheel is assembled, the wheel shaft passes through the center of the wheel, and the two ends of the wheel shaft respectively pass through the through holes of the left dust cover and the right dust cover; then inserting the foot fork into the pocket-shaped cavity of the dust cover, mutually clamping the inverted U-shaped bayonet structure at the lower end of the foot fork and the annular clamping groove structures at the two ends of the wheel shaft, and simultaneously clamping the two lug structures at the lower end of the bayonet spring piece on the annular clamping groove structures by virtue of the elasticity of the bayonet spring piece so as to connect the wheel, the dust cover and the foot fork together; when the wheel is disassembled, the foot fork can be quickly separated from the wheel only by slightly pulling the foot fork upwards with force under the elastic action of the bayonet spring piece lug structure.
According to the invention, the foot fork and the wheel shaft are designed to be matched with each other to form a clamping structure, so that the foot fork and the wheel can be quickly assembled and disassembled; meanwhile, the dust cover with the pocket-shaped cavity structure is designed, so that the wheels can be prevented from being wound by foreign matters, and the joint of the wheel shaft and the foot fork can be prevented from being wound by the foreign matters. The caster wheel can well prevent the caster wheel from being wound by the foreign matters, and can quickly separate the wheel from the fork even if the foreign matters are wound, so that the wound foreign matters can be cleaned conveniently, and the service life of the caster wheel is prolonged.
