Abstract
The utility model relates to a plastic steering bracket truckle. A steering bracket with or without a brake lever is provided with a vertical steering shaft and a horizontal truckle through bearings to form the utility model. The utility model is characterized in that a reinforcing rib structure is fixedly connected between a cambered frame strip of the steering bracket; the middle part of the reinforcing rib is fixedly connected with a bearing seat of the horizontal truckle on the steering bracket and fixedly connected with both ends of the cambered frame strip to form a bowstring structure; the bearing seat of the vertical steering shaft is also fixedly connected into integration. The cambered frame strip, the reinforcing rib and the bearing seat are all integral forming structures. The brake lever is provided with one to two sets of brake pairs. The vertical steering shaft or/ and the horizontal truckle are correspondingly provided with engaging gears which are matched with the brake pairs. The steering bracket, the reinforcing rib, the brake lever and the brake pairs are totally made of light weight engineering plastic materials. The utility model has the advantages of more optimized structure, light weight, low price, convenient technology and manufacture and convenient production manufacturing for factories in China.
Description
[technical field]
The utility model relates to the transportation means field, but is specifically related to the used caster wheel field of a kind of local haul instrument.
[background technology]
Caster wheel for closely, at a slow speed, the transportation device of low-power is particularly suitable, now has been widely used on the hand barrow in many places such as hospital, factory floor, shop, also is used freely-movable bearing as many main equipments etc., purposes is very extensive.But existing caster wheel, its turning rack adopts lightweight metal material such as aluminum alloy through precision cast more, suitably cutting forms again, structure is unreasonable, and (the arc frame bar as whole turning rack is separated from one another, lonely outstanding, globality is relatively poor), technological requirement is very high, the machining clearance complexity, influence factor is more, be difficult to reach desired mechanical strength index, so the turning rack of now domestic high-quality castor is all from developed country's import, not only cost is higher, also be difficult to guarantee the duration, though and adopted light-weight metal, but the castor overall weight still lays particular stress on, the various operation costs of maker are improved, and be not easy to user installation, use, and carrying in particular cases.
[summary of the invention]
At the above-mentioned shortcoming of prior art, technical problem to be solved in the utility model be to provide a kind of structure optimize more and light weight inexpensive, be convenient to processes, be convenient to the plastics turning rack castor that domestic manufacturers manufacture.
For this reason, technical solution of the present utility model is a kind of plastics turning rack castor, be to be equipped with the vertical duction axle by bearing on or without the turning rack of brake lever and horizontal castor constitutes, it is characterized in that: also be fixed with reinforcing rib structure between the arc frame bar of described turning rack.
The middle part of described reinforced rib also with described turning rack on the bearing seat of horizontal castor be connected mutually.
Described reinforced rib and arc frame bar two ends are connected and constitute a bowstring structure, and the bearing seat of vertical duction axle also is solidly fixed.
Described arc frame bar and reinforced rib, bearing seat all are the structures that the one molding forms.
Described brake lever is provided with 1～2 cover brake and pays, and correspondingly described vertical duction axle is or/and horizontal castor is provided with the engaging gear that cooperates braking brake to pay.
Described horizontal castor is the two-wheeled parallel form, and this two horizontal castor is fixed on the horizontal shaft two ends that are supported on the described turning rack.
It all is that the lightweight engineered plastic material is made that described turning rack and reinforced rib thereof, brake lever, brake are paid.
The utility model carries out structure of modification to the turning rack of original aluminum alloy material " the no string of bow is arranged ", two ends, lonely outstanding arc frame bar each other will be separated originally, become one with a reinforced rib captive joint, form a kind of later-model " bowstring structure ", strengthened the structural mechanical property of turning rack greatly; Owing to adopted above-mentioned bowstring structure, strengthened the structural mechanical property of turning rack, therefore relatively weakened requirement to material property, allow people to adopt more light weight, inexpensive, the material of low performance such as engineering plastics are made the critical component-turning rack of castor, and this purpose already by experiment sample confirmed the performance that it is good, laboratory sample proves: it is lighter to the utlity model has weight, being convenient to domestic conditions shapes, and tooling cost such as reduces greatly at remarkable advantage, and, further some other part is also adopted engineering plastics manufacturing, obtained stronger resultant effect;
The utility model structure both can be used for the not turning rack castor of belt brake device, also can be used for having the turning rack castor of single shaft or twin shaft brake gear, and applicability is extensive, belongs to initiative at home, had quite advanced.
Below in conjunction with drawings and Examples the utility model is made and to further specify.
