Abstract
The utility model relates to a telescopic castor, which belongs to the manufacture field of portable household equipment, and comprises a castor composed of wheels, shafts, and a fork plate, and a fixing plate rigidly connected with the fork plate, wherein, a screw rod is fixedly connected between the fixing plate and the fork plate, the upper end surface of a cylinder is matched with the screw rod in a screw form, and the opening of the lower part of the cylinder is covered on the entire castor. The castor of the utility model can extend out the cylinder and can move conveniently, and the castor can also retract in the cylinder and stand without sliding.
Description
The utility model relates to home appliances, and especially portable utensil is made the field.For the roving home appliances of needs,, generally be that castor or cardan wheel are installed in its underpart as sofa, hand barrow etc.(castor is made up of wheel, axle and fork plate usually, and being rigidly connected on the fork plate of castor one is used for the adapter plate that fixes with above-mentioned home appliances base, its connection mode or; Adapter plate directly connects firmly on the fork plate; Or: be fixedly connected with a rigid bar between adapter plate and the fork plate), its advantage is, because the rolling of castor or cardan wheel, moving of sofa or hand barrow just becomes a light nothing the matter, and still, its shortcoming is also given birth to therefrom.Sofa or hand barrow that castor or cardan wheel are installed are difficult to strong fix when static placement, the unstable trend of sliding is always arranged.
The purpose of this utility model is to overcome above weak point and a kind of telescopic castor is provided, solving above-mentioned utensil when the static placement, and problem that can not strong fix.
The purpose of this utility model realizes by following design: a kind of telescopic castor, comprise by wheel, axle, fork plate and form caster wheel, with the rigidly connected adapter plate of fork plate, be fixedly connected with a screw mandrel between this adapter plate and the fork plate, the upper surface of cylindrical shell cooperates as spiral with this screw mandrel, the lower openings of cylindrical shell covers on the whole castor, and this screw mandrel is positioned at the axial location of above-mentioned cylindrical shell.
According to above design, the cylindrical shell upper surface cooperates with the screw mandrel spiral, and promptly cylindrical shell can be along screw mandrel do the upper and lower displacement campaign.To top offset, castor promptly stretches out lower openings end face when utensil (be applicable to mobile) of cylindrical shell to cylindrical shell along screw mandrel; Otherwise, cylindrical shell along screw mandrel to bottom offset, castor promptly withdraw among the cylindrical shell when placement (be applicable to utensil static).Therefore, when the static placement of utensil, the turn cylindrical shell makes the lower openings end face and the ground direct contact of cylindrical shell to bottom offset, thereby strong fix when utensil also just can leave standstill does not have again the unstable phenomenon of sliding to occur.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Accompanying drawing is the schematic perspective view of an embodiment of the utility model.
In the accompanying drawing, axle 9 is erected on the fork plate 8, wheel 7 and 9 movable connections of axle, promptly by wheel 7, fork plate 8 and axle 9 forms castor (also can add bearing as, but spool 9 axle sleeves on a bearing, the outer ring of bearing connects firmly a rubber wheel again, fork plate 8 connects firmly with axle 9) concerning existing castor, adapter plate 1 is directly to fix with fork plate 8, perhaps, is fixedly connected with a rigid bar between adapter plate 1 and the fork plate 8.In the utility model, be fixedly connected with a screw mandrel 3 between adapter plate 1 and the fork plate 8, the upper surface of cylindrical shell 5 cooperates with screw mandrel 3 spirals, the upper surface that is cylindrical shell 5 is provided with the negative thread (directly offering tapped bore on the upper surface of cylindrical shell and 5) that matches with screw mandrel 3, accompanying drawing illustrates another kind of mode, promptly connects firmly mutually with cylindrical shell 5 with screw mandrel 3 spiral nut engaged 4.Be fixedly connected with handle 10 on the screw mandrel 3, be used for turn screw mandrel 3 and do spiral rising or descending motion with respect to cylindrical shell 5.Hole 2 on the adapter plate 1 is as using the utility model and other utensil (as sofa) when fixing, cylindrical shell 5 outsides are fixedly connected with knob 2 (1-4), so that turn cylindrical shell 5.Concerning cardan wheel, fully as shown in drawings, only needing to change castor into cardan wheel can become telescopic cardan wheel (non-rolling position, the top of cardan wheel and screw mandrel 3 connect firmly).This telescopic cardan wheel also belongs to the protection domain of utility model.
