Detailed description of the invention
Referring to figs. 1 through Fig. 5, the castor embodiment of the utility model band cleaning mechanism is described further.
With a castor for cleaning mechanism, comprise mount pad 3, Connection Block 1, roller 4 and protective cover 2, Connection Block 1 comprise the turning cylinder 11 that is rotationally connected with mount pad 3 and with the mounting rod 12 for installing roller 4, mounting rod 12 and turning cylinder 11 are connected in " L " font.By the setting of protective cover 2, protective action can be played by actv. pair roller 4, avoid weight, impurity etc. directly to drop into castor inside, roller 4 is blocked, affect roller 4 and rotate.Simultaneously, turning cylinder 11 is provided with and rotates round end 111, by rotating round end 111 and coordinating between rotation hole 32 on mount pad 3, make to relatively rotate around axis between turning cylinder 11 and mount pad 3, thus the roller 4 achieved on castor, can be rotated the axis direction 360 ° rotation of moving axis 11, changes the sense of motion of castor.Simultaneously, at impurity along with roller 4 rotates, when entering castor inside, conveniently clear up, protective cover 2 is also provided with above roller 4, and protective cover 2 slip is connected on turning cylinder 11, when after castor a period of time, inside is wound with impurity, cause rotating at need, by by protective cover 2 along turning cylinder 11 to one end slippage away from roller 4, make, between roller 4 and protective cover 2, there is space, simultaneously, by being arranged on the inhibiting device 13 on turning cylinder 11, protective cover 2 position can be fixed, avoid protective cover 2 landing in scale removal process, the inner impurity of easy cleaning, extend the service life of castor.
Protective cover 2 comprises and overlaps the axle sleeve 22 penetrated on turning cylinder 11 and the arc 21 for side roller 4, and axle sleeve 22 radial direction row is provided with the spacing hole 23 coordinated with inhibiting device 13.When the inner impurity of castor is too much, by by the axle sleeve 22 of protective cover 2 along turning cylinder 11, to one end slippage away from roller 4, make to form space between protective cover 2 and roller 4, impurity is facilitated to clear up, simultaneously, axle sleeve 22 is arranged spacing hole 23, when protective cover 2 slippage is opened, by the fit form of spacing hole 23 with inhibiting device 13, when can make protective cover 2 on side roller 4 and cleaning impurity two positions, carry out spacing, can not only be more stable when side roller 4, the also convenient cleaning work to impurity.
Preferably, inhibiting device 13 is comprised and is arranged on turning cylinder 11 slotted eye 131 in the radial direction, is arranged on the spring 133 in slotted eye 131 and is conflicted to the ball 132 of slotted eye 131 mouthfuls by spring 133.Using the form of ball 132 and spring 133 as stop gear, when the axle sleeve 22 on protective cover 2, pass through slippage, make the position of ball 132 on spacing hole 23 position on axle sleeve 22 and stop gear to pair time, ball 132 is outwards ejected by the effect of spring 133, be stuck in the spacing hole 23 of axle sleeve 22, realize the restriction to axle sleeve 22 position, simultaneously, protective cover 2 is needed to remove, when impurity in pair roller 4 is cleared up, by pressing ball 132, spring 133 is compressed, ball 132 is inwardly pressed in slotted eye 131, again axle sleeve 22 slippage is left, and stop gear is provided with two, be respectively used to protective cover 2 is limited on roller 4 position, pair roller 4 is protected, and be arranged on the other end of turning cylinder 11 counter roller 4, for the fixedly separated protective cover 2 opened, impurity is facilitated to clear up.
Further, slotted eye 131 opening part diameter is less than ball 132 diameter, and ball 132 can be avoided to drop in slotted eye 131, ensures the integraty of stop gear.Further, be regular hexagon by turning cylinder 11 cross-sectional plane, the inside face of axle sleeve 22 is the regular hexagon matched with turning cylinder 11, orthohexagonal cross-sectional plane, axle sleeve 22 and turning cylinder 11 can be made to relatively rotate, ensure that arc 21 can be positioned at above roller 4 all the time, prevent impurity from directly dropping in roller 4, and orthohexagonal structure, can mutual slip between easier turning cylinder 11 and axle sleeve 22, make arc 21 better protecting effect, during cleaning, more convenient operation.
Simultaneously, runner is provided with two, and be positioned at the both sides of mounting rod 12, two rollers 4 are rotatably connected on mounting rod 12 by roller bearing 5, mounting rod 12 is provided with roller bearing hole 121, by roller bearing hole 121, when roller bearing 5 is mounted on mounting rod 12, can relatively rotate, therefore achieve relatively rotating of roller 4 and mounting rod 12.Simultaneously, rotation round end 111 diameter on turning cylinder 11 is less than the incircle of turning cylinder 11 regular hexagonal section, therefore, when installing protective cover 2 and turning cylinder 11, after the regular hexagon inside protective cover 2 Upper shaft sleeve 22 is matched with the regular hexagon of turning cylinder 11, connection, being rotated by turning cylinder 11 is mounted on mount pad 3 again, mount pad 3 being provided with the mounting hole 31 for installing castor, can castor being mounted to above baggage container, swivel chair etc. by mounting hole 31, making carrying more convenient.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
