Abstract
The utility model discloses a castor which can ensure that the relative position of an inner castor and an outer castor is fixed. The castor comprises the inner castor and the outer castor, wherein the inner castor is used for installing a rotating shaft, and the outer castor is arranged on the outer side of the inner castor. An annular boss is arranged in the middle of the annular side face of the inner castor. The two sides, on the annular side face of the inner castor, of the annular boss form a pair of circular beads. A plurality of connecting through holes are formed in the surface of the annular boss. An annular groove matched with the annular boss is formed in the middle of the annular side face of the inner side of the outer castor. Connecting columns corresponding to the connecting through holes in a one-to-one mode are arranged on one pair of side faces of the annular groove. The castor can be widely used in various universal wheels.
Description
Technical field
The utility model relates to a kind of cardan wheel being arranged in various glide, is specifically related to the castor on a kind of cardan wheel.
Background technology
At present, for the castor in the glide such as tote cart, its structure comprises: for the interior wheel of turning cylinder being installed and being arranged on interior foreign steamer of taking turns outside, the middle part of the annular side of inside taking turns is provided with annular boss, make interior annular side of taking turns form a pair of shoulder in the both sides of annular boss, the middle part of the interior annular side of described foreign steamer offers the annular groove matching with annular boss.This castor adopts the method for quadric injection mould to be made conventionally.Owing to not guaranteeing the inside and outside fixing detent mechanism of relative position of taking turns between inside and outside wheel, the cardan wheel that adopts this castor to be made, in actual use, when easily skidding in situation wet and slippery and heavily loaded on road, has affected normally sliding of castor; And, while skidding, also change the friction mode on foreign steamer and ground, become cliding friction from friction of rolling, accelerate the wearing and tearing of foreign steamer, shorten the service life of castor.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of and can guarantee the fixing castor of inside and outside relative position of taking turns.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of castor, comprise the interior interior foreign steamer of taking turns outside of taking turns and be arranged on, the middle part of the annular side of inside taking turns is provided with annular boss, make interior annular side of taking turns form a pair of shoulder in the both sides of annular boss, on the surface of described annular boss, be provided with several connecting through holes, the middle part of the interior annular side of described foreign steamer offers the annular groove matching with annular boss, is provided with and connecting through hole joint pin one to one in the pair of sidewalls of annular groove.
Spacing between adjacent connecting through hole all equates between two.
On described interior at least one side end face of taking turns, be provided with several covering of the fan type pits, the connecting portion between adjacent covering of the fan type pit is taken turns the radial reinforced rib of inside and outside circle in forming and connecting between two.
On described interior both sides end face of taking turns, be provided with several covering of the fan type pits, the connecting portion between adjacent covering of the fan type pit is taken turns the radial reinforced rib of inside and outside circle in forming and connecting between two.
Several described covering of the fan type pits are evenly distributed on interior end face of taking turns a corresponding side.
The width that is positioned at a pair of shoulder of annular boss both sides in described interior annular side of taking turns equates.
The width of described shoulder be equivalent to annular boss thickness 3/8ths to 5/8ths between.
The beneficial effects of the utility model are: be used to form connecting through hole owing to having offered on annular boss; in the time that quadric injection mould forms foreign steamer; form joint pin; inside and outside relative position of taking turns is fixed; guarantee that castor is wet and slippery and can normally slide heavily loaded in the situation that on ground; reduce the friction on foreign steamer and ground, extended the service life of castor.In addition, owing to being provided with several covering of the fan type pits on interior end face of taking turns, connecting portion between adjacent covering of the fan type pit is taken turns the radial reinforced rib of inside and outside circle in forming and connecting between two, reduce on the one hand the weight of castor, reduce material cost, having improved on the other hand the weight capacity of whole castor, is to kill two birds with one stone.

Reference numeral in Fig. 1 to Fig. 3 is: 1, interior wheel, 10, centre hole, 2, annular side, 21, shoulder, 3, covering of the fan type pit, 4, radial reinforced rib, 5, annular boss, 6, connecting through hole, 7, foreign steamer.
The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiments of castor described in the utility model in detail.
As Fig. 1, shown in Fig. 3, a kind of castor described in the utility model, comprise: by an injection moulding form interior wheel 1 and be formed on interior foreign steamer 7 of taking turns 1 outside by quadric injection mould, the center of inside taking turns 1 end face is provided with the centre hole 10 for turning cylinder is installed, as shown in Figure 2, the middle part of inside taking turns 1 annular side 2 is provided with annular boss 5, make interior 1 the annular side 2 of taking turns form a pair of shoulder 21 in the both sides of annular boss 5, this width W 1 to shoulder 21 equates, be equivalent to annular boss 5 thickness W2 3/8ths to 5/8ths between, be generally 1/2nd, on the surface of annular boss 5, be circumferentially evenly provided with several connecting through holes 6, that is: the spacing between adjacent connecting through hole 6 all equates between two, and be greater than the width of connecting through hole 6, the middle part of the interior annular side of described foreign steamer 7 offers the annular groove matching with annular boss 5, in the pair of sidewalls of annular groove, be provided with and connecting through hole 6 joint pin one to one.In the present embodiment, described interior wheel on 1 both sides end face is all evenly provided with six covering of the fan type pits 3 (can be also through covering of the fan type through hole), between two the connecting portion between adjacent covering of the fan type pit 3 form and connect in the radial reinforced rib 4 of inside and outside circle of wheel 1.
