Detailed description of the invention
For the ease of the understanding of those skilled in the art, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
In one of them embodiment of the present utility model, provide a kind of Demountable caster, as shown in accompanying drawing 1,2,3,4,5,6, the wheel seat 2 comprising permanent seat 1 and be connected on permanent seat 1, and being divided into the wheel 3 of wheel seat 2 both sides, namely as a whole castor comprises two wheels 3 that wheel seat about 2 splits; Wheel seat 2 is provided with axis hole 5, is equipped with rotating shaft 6 in axis hole 5, and wheel 3 is fixed on rotating shaft 6 two ends.In the present embodiment, wheel 3 has multiple with the fixed form of rotating shaft 6, and such as rotating shaft 6 two ends arrange pin-and-hole, inserts latch and be fixed in rotating shaft 6 by wheel 3 when wheel 3 is loaded onto in rotating shaft 6, also screw thread can be set at rotating shaft 6 two ends, fixed by nut locking when wheel 3 is loaded onto in rotating shaft 6, do not limit concrete connection mode at this, therefore, wheel 3 is when damaging, replaceable single wheel 3, without integral replacing castor, economizes on resources.The lateral surface of two wheels 3 is snapped with end cap 12, and wheel 3 is provided with hole clipping 13, and end cap 12 is provided with the buckle 14 coordinated with hole clipping 13; The back of buckle 14 is provided with reinforced rib, can strengthen fastening power, also can ensure that in repeatedly disassembly and assembly be that buckle 14 can not produce fatigue failure.The setting of end cap 12 can prevent that dust etc. is dirty to be entered in wheel, ensure that castor rolls in use smooth and easy, and adopts snap fit to facilitate to change end cap 12 at any time.Be provided with axle sleeve 7 between rotating shaft 6 and wheel 3, axle sleeve 7 outside face is provided with clamping projection 8, is provided with the buckling groove mated with clamping projection in the centre hole of wheel 3.For increasing the area of contact of buckling groove and clamping projection 8, slow down rate of depreciation, the present embodiment clamping projection 8 and buckling groove are all set to as strip shape, and length bearing of trend is identical with the axis of rotating shaft 6.In the present embodiment, castor is when rolling, and can fix for rotating shaft 6, axle sleeve 7 rotates along rotating shaft 6 rotating band driving wheel 3; Also can be rotating shaft 6 relative with axle sleeve 7 fixing, rotating shaft 6 drives wheel 3 to rotate; Or can rotate for rotating shaft 6, axle sleeve 7 phase countershaft 6 is also rotatable, realizes two wheels 3 and does not restrict mutually, make wheel 3 contact with ground surface and realize turning.
Be connected and fixed by detachable pipe link 4 between permanent seat 1 and wheel seat 2, wheel seat 2 is provided with the connecting element of fixed connecting rod 4; In the present embodiment, pipe link 4 upper end is major part, and lower end is shaft position, and shaft position is provided with annular groove 41; Permanent seat 1 is provided with through hole 9, the wheel seat 2 corresponding with through hole 9 position is provided with wheel seat counterbore 10, pipe link 4 is through through hole 9, upper end is connected on through hole 9 aperture, lower end grafting is fixed in wheel seat counterbore 10, the connecting element be located on wheel seat 2 is connected in restriction pipe link about 4 play in annular groove 41, achieves the fixing of castor; The present embodiment connecting element is bolt, and wheel seat 2 is provided with the fixed orifice 11 penetrating wheel seat 2, and bolt is through fixed orifice 11, and one end is connected on wheel seat 2 by bolt head, and the other end is fixed by nut locking; In the present embodiment, nut is non-standard component, nut periphery is circular, an end face is provided with the screw-threaded counterbore of mating with bolt, another end face is provided with interior hexagonal counterbore or plum blossom counterbore, screw-threaded counterbore is that lock bolt uses, and interior hexagonal counterbore or plum blossom counterbore are coordinate spanner to use when assembling fixing and dismounting and change.Fixed orifice 11 one end open is the polygon counterbore 111 with bolt head form fit, the other end is the circular counter bore 112 with nut form fit, nut is rotatable in circular counter bore, therefore locking or dismounting can be realized, and regular nut in the Castor structure of the present embodiment can only interlocking in wheel seat outer end, and can bolt be exposed, the easy corrosion of bolt, and wheel spacing can be increased.When being locked, bolt head submerges in polygon counterbore 111, nut submerges in circular counter bore 112, the head of nuts and bolt is concordant with the surface of wheel seat, seem that profile is succinct, the spacing between two wheels 3 can be shortened, avoid the spacing increased between two wheels because bolt two ends will be dodged, also can reduce the space of draw-bar box indent simultaneously.
The castor that the present embodiment provides, wheel 3 has two kinds of dismounting modes, a kind of for changing single wheel 3, another kind of for change whole wheel seat 2 by connecting element, can change, economize on resources according to the different damage rates of castor.
The utility model another embodiments provides a kind of suitcase, this draw-bar box comprises the Demountable caster in casing, telescopic bar and above-described embodiment.Draw-bar box have employed above-mentioned Demountable caster, solves that traditional Castor for trunk or bag can not be changed, the problem of maintenance difficult, avoids the wasting of resources behavior abandoning whole case and bag because castor can not change.
Above-described embodiment is preferably implementation of the present utility model, is not to restriction of the present utility model, and under the prerequisite not departing from inventive concept of the present utility model, any apparent replacement is all within protection domain of the present utility model.
