Abstract
The utility model discloses a support rolling wheel for a small cargo trailer. The support rolling wheel comprises a support seat main body (1), wherein the upper part of the support seat main body (10) is provided with a mounting inner screw hole (2), the lower part of the support seat main body (1) is provided with two support arms (3), and two rolling wheels (4) which are arranged in a parallel and adjacent manner are arranged between the two support arms (3). The support rolling wheel has the advantages that the bearing capability is high, the centre-of-gravity position is low, stability is high, the structure is simple, and cost is low.
Description
Technical field
The utility model relates to towing appliance, is specifically related to a kind of supporting scroll wheel for the goods towing dolly.
Background technology
The goods towing dolly is storage field towing appliance commonly used.The goods towing dolly in use, often need stop and moving, but, the supporting scroll wheel of the goods towing dolly of prior art is generally the single-wheel structure, because in order to support the needs of weight, it is bigger generally must wheel to be set, therefore the whole center of gravity of the supporting scroll wheel of the goods towing dolly that causes is higher, and the regular general cargo towing dolly does not all have braking mechanism, therefore make the goods towing dolly when stopping, easily owing to ground does not steadily produce moment of transference, cause the goods towing dolly to be moved, thereby cause goods to bump, tilt even avalanche, cause serious economy loss.
Summary of the invention
The technical problems to be solved in the utility model provides that a kind of weight capacity is good, center-of-gravity position is low, good stability, the supporting scroll wheel that is used for the goods towing dolly simple in structure, with low cost.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of supporting scroll wheel for the goods towing dolly, comprise the supporting base body, described supporting base upper part of body is provided with the installation inner bolt hole, and the bottom of described supporting base body is provided with two hold-down arms, be provided with two scroll wheels between described two hold-down arms, described two scroll wheels adjacent layout arranged side by side.
As further improvement in the technical proposal:
Described supporting base upper part of body is provided with cylinder table, and described installation inner bolt hole is located on the axis of described cylinder table.
Described two scroll wheels size is identical and be fixed between described two hold-down arms by same anchor shaft.
The utlity model has following advantage: the utility model is because the bottom of supporting base body is provided with two hold-down arms, be provided with two scroll wheels between two hold-down arms, two scroll wheel adjacent layouts arranged side by side, therefore load-bearing can be shared fully between two scroll wheels of adjacent layout arranged side by side, weight capacity is better, and can reduce the whole center-of-gravity position of whole supporting base body, thereby make that the center of gravity of goods towing dolly is lower, be not easy in use to slide, stability is better during placement, and it is good to have weight capacity, center-of-gravity position is low, good stability, simple in structure, advantage with low cost.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the perspective view of the utility model embodiment.
Fig. 2 is the side-looking structural representation of the utility model embodiment.
Marginal data:
1, supporting base body; 11, cylinder table;
2, inner bolt hole is installed; 3, hold-down arm; 4, scroll wheel.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
As depicted in figs. 1 and 2, the supporting scroll wheel that present embodiment is used for the goods towing dolly comprises supporting base body 1, the top of supporting base body 1 is provided with installs inner bolt hole 2, the bottom of supporting base body 1 is provided with two hold-down arms 3, be provided with 4, two scroll wheels of two scroll wheels, 4 adjacent layouts arranged side by side between two hold-down arms 3.Present embodiment is because the bottom of supporting base body 1 is provided with two hold-down arms 3, be provided with two scroll wheels 4 between two hold-down arms 3, two scroll wheel 4 adjacent layouts arranged side by side, therefore load-bearing can be shared fully between two scroll wheels 4 of adjacent layout arranged side by side, weight capacity is better, and can reduce the whole center-of-gravity position of whole supporting base body 1, thereby make that the center of gravity of goods towing dolly is lower, be not easy in use to slide, stability is better during placement, and it is good to have weight capacity, center-of-gravity position is low, good stability, simple in structure, advantage with low cost.
In the present embodiment, the top of supporting base body 1 is provided with cylinder table 11, inner bolt hole 2 is installed is located on the axis of cylinder table 11, makes that the length of thread that inner bolt hole 2 is installed is longer, and structural strength is higher.
In the present embodiment, two scroll wheels, 4 sizes are identical and be fixed between two hold-down arms 3 by same anchor shaft, and this structure is installed more simple and convenient.
The above only is preferred implementation of the present utility model, and protection domain of the present utility model is not limited in above-mentioned embodiment, and every technical scheme that belongs to the utility model principle all belongs to protection domain of the present utility model.For a person skilled in the art, some improvements and modifications of under the prerequisite that does not break away from principle of the present utility model, carrying out, these improvements and modifications also should be considered as protection domain of the present utility model.
