Abstract
The utility model relates to a member of a baggage handcart which is used in shopping malls, stations, airports and the like, in particular to a baggage handcart wheel which is used for solving the problems of unstable structure and high cost in the traditional wheel. The baggage handcart wheel comprises a wheel boss and a wheel rim installed on the wheel boss, wherein the circumferential edge of the wheel boss is evenly distributed with axial through hole grooves; the circumferential roller face of the wheel boss is evenly distributed with cambered open slots; the inner side of the circumference of the wheel rim tallies with the axial through hole grooves and the cambered open grooves of the wheel boss in shape; and the wheel rim and the wheel boss are compounded into an integral body through injection molding. Compared with the traditional structure of which the outer side of the circumference of the wheel boss is in a groove shape and contains the wheel rim, the wheel rim and the wheel boss are compounded into an integral body through injection molding, and the axial through hole grooves and the cambered open grooves are arranged on the wheel rim, the thickness of the wheel rim and the production cost are reduced, the positioning and the combination of the wheel boss and the wheel rim are more stable without easily generating relative shift.
Description
Technical field
The utility model relates to the member of the baggage cart that uses on ground such as market, station, airport, refers to a kind of baggage cart wheel particularly.
Background technology
At present, the wheel that has the used diameter 180mm of baggage cart now generally adopts the punching press of plastics core wheel to rivet the structure of natural rubber wheel rim.Because in this structure, the employed material contracts amount of core wheel and wheel rim is inconsistent, so the quality instability of riveted joint back product; And because need punching press riveted joint, so the natural rubber wheel rim must have enough thickness to have enough elastic extension rates to guarantee it, cost height so not only, and cause wheel to be difficult to the requirement of satisfied use because of wheel rim relatively moves easily with core wheel.
Summary of the invention
The purpose of this utility model is exactly to overcome high with the cost built on the sand problem of above-mentioned existing car wheel structure, provide a kind of steady quality reliable, be convenient to the mechanization batch manufacturing, and baggage cart wheel with low cost.
For achieving the above object, the baggage cart that provides of the utility model comprises core wheel with wheel and is installed in wheel rim on the core wheel.The circumferential edges place of described core wheel is evenly equipped with the axially extending bore groove, is evenly equipped with the circular arc open slot on the circumference tread of described core wheel.The shape of the inside circumference shape of described wheel rim and the axially extending bore groove of described core wheel and circular arc open slot matches.Described wheel rim and core wheel are compound by injection moulding to be one.
Further, the axially extending bore groove of described core wheel and circular arc open slot are staggered arrangement states at interval in a circumferential direction.
The axially extending bore groove of described core wheel and circular arc open slot respectively are furnished with four to eight.
The axially extending bore groove of described core wheel and circular arc open slot can respectively be furnished with six.
Described wheel rim is the wheel rim of elastic body material preferably.
The beneficial effects of the utility model are: wheel rim and core wheel are compound by injection moulding to be one, and the setting of axially extending bore groove and circular arc open slot on the wheel rim, the structure that is the groove shape with traditional core wheel periphery and holds wheel rim is compared, the thickness of wheel rim significantly reduces, productive costs is reduced, on the other hand, the location of core wheel and wheel rim and combination more firmly are difficult for relatively moving; Wheel rim adopts the elastic body material, makes the performances such as elasticity, intensity and resistance to abrasion of wheel product obviously strengthen, and not only Mechanized Processing is more convenient, and can recycle.
Description of drawings
Fig. 1 is the structural representation of the baggage cart of diameter 180mm with wheel;
Fig. 2 is the A-A sectional structure scheme drawing of Fig. 1;
Among the figure, wheel rim 1, core wheel 2, deep groove ball bearing 3, packing ring 4, interior cover 5, wheel cap 6, axially extending bore groove 7, circular arc open slot 8.
The specific embodiment
Below in conjunction with the drawings and specific embodiments baggage cart of the present utility model is made of wheel and to be described in further detail:
As depicted in figs. 1 and 2, this baggage cart wheel, diameter is 180mm, comprises core wheel 2 and the wheel rim 1 that is installed on the core wheel 2.Core wheel 2 is connected with pivot pin by two 6203 moldeed depth ditch ball-bearing casings 3, is provided with packing ring 4 between two deep groove ball bearings 3, cover 5 in being arranged with on the pivot pin.The both sides of core wheel 2 also are provided with wheel cap 6.The circumferential edges place of core wheel 2 is evenly equipped with six axially extending bore grooves 7, be evenly equipped with six circular arc open slots 8 on its circumference tread, and axially extending bore groove 7 and circular arc open slot 8 are staggered arrangement states at interval in a circumferential direction so that the location of core wheel 2 and wheel rim 1 with combine.The shape of the inside circumference shape of wheel rim 1 and the axially extending bore groove 7 of core wheel 2 and circular arc open slot 8 matches.Add man-hour, wheel rim 1 is compound by injection moulding with core wheel 2 to be one, core wheel 2 first injection moldeds, and wheel rim 1 serves as the axle injection molded with core wheel 2 then, the material of wheel rim 1 can be elastic bodys such as TPR, TPE, TPV, with wear-resistant, antiageing, and can repeated usage.
