Description
Technical field
The utility model relates to the hand barrow technical field, the caster bracket that particularly a kind of hand barrow is used.
Background technology
The hand barrow batch manufacturing starts from 1840s, and is bringing into play very important effect in retail and wholesale market always.Hand barrow has metal or plastic container are stored goods, and hand barrow frame basket is supported by two front-wheels and two trailing wheels, and front-wheel can rotate by 360 degree, and trailing wheel generally is a directional wheel, can not rotate.Generally from back go-cart control car, the rotation of front-wheel makes the user can control car more easily to the user.Also have four wheels of some hand barrows all to use cardan wheel, four wheels in front and back all can rotate by 360 degree.
The caster bracket straddle mounting is in wheel top, the general top board that uses with double-deck bearing hoodle structure, upper strata steel bowl is provided with 10 hoodles (being positioned on the top board), and lower floor's steel bowl is provided with 10 hoodles, ironcasting passes bearing, and up load is in car body, and bearing arrangement can rotate by 360 degree support.
The late nineteen eighties, the load capacity of hand barrow constantly increases, and the load that bears of bearing is also increasing like this, and the carrying of steel ball is overweight, and the friction between steel bowl and the steel ball increases, and often causes rotating fault and takes place, and has influenced the service life of cardan wheel.Particularly hand barrow is often washed by water blast gun, and the bearing after the flushing often is in no oil or oil starvation state, and in this case, car body weight is big approximately, and the friction between bearing steel bowl and the steel ball is also big more, has reduced the service life of cardan wheel greatly.
The price one tunnel of steel is high at present, and productive costs climbs up and up.For the manufacturer of hand barrow, control the total amount of hand barrow self and reduce production costs most important.
Summary of the invention
The technical problems to be solved in the utility model is, provides a kind of in light weight, and cost of manufacture is low, the caster bracket that the hand barrow of long service life is used.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is, the caster bracket that a kind of hand barrow is used, comprise wheel, base and bearing, the lower end of the base wheel that is rotationally connected, the upper end connection bearing of underframe is characterized in that: also comprise a pole, this pole hollow, its upper end sidewall is provided with the assembling through hole, the lower end is provided with screw through-hole by the connecting strap shutoff on the connecting strap, a stock screw passes this screw hole and cooperates with nut, the screw mandrel enemy of stock screw is provided with major axis, and this major axis matches with bearing on the underframe.
Described bearing is double-deck hoodle bearing, on its lower floor's steel bowl excircle some double wedges is set, and a side of lower floor's steel bowl is provided with brake lever, and the front end of brake lever is provided with the brake tooth that matches with double wedge on the lower floor steel bowl excircle, and the rear end of brake lever is provided with brake facing.
The upper end of pole is by the rubber sheet gasket shutoff.
Also be provided with support pad between pole and the bearing.
The pole that the utility model adopts hollow is connected with bearing on the underframe by the stock screw, has reduced the weight of hand barrow self in the assurance load capacity, and the consumption of having saved steel has reduced productive costs.Owing to reduced the weight of hand barrow self, the friction force of bearing steel bowl and steel ball reduces greatly so simultaneously.Particularly be cleaned the situation of back steel bowl inner oil shortage at hand barrow, the friction force between reduction bearing steel bowl and the steel ball can promote the service life of caster bracket.
Lower floor's steel bowl of pole and bearing is fixed, on the excircle of lower floor's steel bowl double wedge is set, on the brake lever of lower floor's steel bowl one side the brake tooth is set, when needing brake, move the handle of brake lever, brake tooth on the brake lever is mutually meshing with double wedge, and the brake facing on the brake lever is close to wheel simultaneously, stops the rotation of cardan wheel in brake.
In sum, the utlity model has in light weightly, cost of manufacture is low, and long service life can be stopped the beneficial effect that cardan wheel rotates simultaneously in the process of brake.

The specific embodiment
As Fig. 1, shown in Figure 2, the bottom of bearing 2 wheel 1 that is rotationally connected, the upper end of bearing is provided with a double-deck hoodle bearing 3, on lower floor's steel bowl excircle of this bearing 18 double wedge 3a are set, one side of lower floor's steel bowl is provided with brake lever 4, this brake lever 4 is rotatably connected on the bearing 2, and the front end of brake lever is provided with 3 brake tooth 4a, and the rear end of brake lever is provided with a brake facing 4b, when needs brake, press down the handle 4c of brake lever, the double wedge 3a of the brake tooth 4a of brake lever front end and lower floor's steel bowl excircle is meshing, and brake facing 4b holds wheel tightly, when stopping wheel 1 rolling, stop the rotation of cardan wheel like this.
The upper end of bearing 2 connects the pole 8 of hollow, the upper end sidewall of this pole is provided with assembling through hole 8a, the lower end is by connecting strap 9 shutoff, screw through-hole 9a is set on the connecting strap 9, the stock screw passes this screw hole 9a and cooperates with two nuts 7, and screw mandrel 6 enemies of stock screw are provided with major axis 5, this major axis 5 double-deck hoodle bearing 3 on the bearing 2 that is rotationally connected, a support pad 10 also is set between pole 8 and the bearing 2, is used for strengthening being connected of pole and bearing.The upper end of pole 8 is by rubber sheet gasket 11 shutoff.
