Abstract
The invention discloses a trundle capable of guaranteeing the fixed relative position between an inner wheel body and an outer wheel body. The trundle comprises the inner wheel body for installing a rotating shaft and the outer wheel body arranged on the outer side of the inner wheel body. An annular boss is arranged in the middle of the annular side face of the inner wheel body, a pair of circular beads are formed on the two sides of the annular boss through the annular side face of the inner wheel body, a plurality of connecting through holes are formed in the surface of the annular boss, the middle of the annular side face of the inner side of the outer wheel body is provided with an annular groove matched with the annular boss, and a pair of side walls of the annular groove is provided with connecting columns corresponding to the connecting through holes in a one-to-one mode. The trundle can be widely applied to various universal wheels.
Description
Technical field
The present invention relates to a kind of cardan wheel being arranged in various glide, be 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, easily skids in wet and slippery and heavily loaded situation on road, has affected normally sliding of castor; And, while skidding, also changed the friction mode on foreign steamer and ground, from friction of rolling, become cliding friction, accelerated the wearing and tearing of foreign steamer, shortened the service life of castor.
Summary of the invention
Technical matters to be solved by this invention 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 used in the present invention 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.
Beneficial effect of the present invention is: owing to having offered on annular boss, be used to form connecting through hole; when quadric injection mould forms foreign steamer; form joint pin; inside and outside relative position of taking turns is fixed; guaranteed 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, reduced on the one hand the weight of castor, reduced material cost, having improved on the other hand the weight capacity of whole castor, is to kill two birds with one stone.
Accompanying drawing explanation
Fig. 1 is interior structural representation of taking turns of the present invention.
Fig. 2 is that the left TV structure signal of Fig. 1 is longer.
Fig. 3 is the structural representation of castor of the present invention.
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 of the present invention in detail.
As Fig. 1, shown in Fig. 3, a kind of castor of the present invention, comprise: the interior wheel 1 forming by an injection moulding 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 for the centre hole 10 of 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 in the both sides of annular boss 5, form a pair of shoulder 21, 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.
