Abstract
The invention discloses a bearing roller for a tow truck for goods, and the roller comprises a bearing seat body (1); an installation internal screw hole (2) is arranged in the upper part of the bearing seat body (1); two support arms (3) are arranged at the lower part of the bearing seat body; two rollers (4) are arranged between the two support arms (3); and the two rollers (4) are arranged adjacently in parallel. The bearing roller for the tow truck for goods has the advantages of good load bearing capability, low gravity position, good stability, simple structure and low cost.
Description
Technical field
The present invention relates to towing appliance, be 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 to stop and moving, but, the supporting scroll wheel of the goods towing dolly of prior art is generally the single-wheel structure, because the needs for a load-bearing material, it is larger generally must wheel to be set, the whole center of gravity of the supporting scroll wheel of the goods towing dolly that therefore causes is higher, and the regular general cargo towing dolly does not all have braking mechanism, therefore so that the goods towing dolly when stopping, easily owing to ground does not steadily produce moment of transference, causes the goods towing dolly to be moved, thereby cause goods to bump, tilt even avalanche, cause serious economic loss.
Summary of the invention
The technical problem to be solved in the present invention 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 used in the present invention is:
A kind of supporting scroll wheel for the goods towing dolly, comprise the supporting base body, the top of described supporting base 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:
The top of described supporting base 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 present invention has following advantage: the present invention 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 so 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 embodiment of the invention or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the perspective view of the embodiment of the invention.
Fig. 2 is the side-looking structural representation of the embodiment of the invention.
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 the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention are 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 so 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, so that the length of thread of installation inner bolt hole 2 is longer, 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 invention, and protection scope of the present invention is not limited in above-mentioned embodiment, and every technical scheme that belongs to the principle of the invention all belongs to protection scope of the present invention.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 invention, carrying out, these improvements and modifications also should be considered as protection scope of the present invention.
