The utility model discloses it is right the spacing mode of tarpaulin spool 2 does not do specifically and restricts, and it contains but not limited to the condition enumerated in the following embodiment:

example 1: in this embodiment, the bracket 1 and the tarpaulin reel 2 are both provided with magnetic members, and the magnetic members attract each other under the action of magnetic force, so that the tarpaulin reel 2 is always attached to the bracket 1 and moves along the bracket 1.

Example 2: as a preferred embodiment, a sliding groove is formed in one side of the bracket 1 facing the tarpaulin reel 2, and the tarpaulin reel 2 is provided with a sliding block which is located in the sliding groove and moves along the sliding groove.

Due to the arrangement of the sliding grooves, the tarpaulin reel 2 can move along the support 1 all the time, and the moving stability is guaranteed. In addition, the sliding groove can limit the tarpaulin reel 2, and prevent the tarpaulin reel 2 from moving in a direction away from the bracket 1, for example, the tarpaulin reel 2 flies or inclines due to wind blowing.

The present embodiment is not particularly limited to the arrangement position of the slide groove, and preferably, the bracket 1 has a guide bar on which the slide groove is arranged, and the guide bar includes a lateral portion parallel to the bearing portion 12 and a vertical portion parallel to the support portion 11. Of course, the sliding groove may be opened in the supporting portion 11 and the supporting portion 12 to simplify the structure of the bracket, and is not limited in detail herein.

As a preferred embodiment of the present invention, as shown in fig. 8 and 10, the covering member 3 is provided with a tightening shaft 6 perpendicular to the tarpaulin reel 2 at one side of the tarpaulin reel 2, and the tightening shaft 6 can rotate around its axis and can move up and down with respect to the covering member 3.

The tightening shaft 6 rotates towards the edge of the tarpaulin, and the tarpaulin positioned on one side of the tarpaulin unfolding direction is wound on the tightening shaft 6 to tighten the tarpaulin in the direction perpendicular to the tarpaulin unfolding direction, so that the tarpaulin at the top is prevented from collapsing. Meanwhile, the tensioning shaft 6 moves downwards, so that the tarpaulin completely covers the covering part 3, the covering effect is improved, and wind and sand are prevented from blowing into the carriage from one side of the bracket 1.

As a preferred embodiment, be provided with the magic son on the stayguy 6 and paste, the tarpaulin is provided with the female subsides of magic, the magic son is pasted and is pasted with the female laminating of magic, makes the tarpaulin be in the winding on the stayguy 6 is more effective, prevents that the tarpaulin from skidding.

It should be noted that the tarpaulin cover folding device of the present invention is not only suitable for various vehicles for transporting goods, such as general trucks, van trucks, flat trucks, etc., but also suitable for small vehicles with carriages, such as tricycles, etc., and is not limited thereto.

In addition, the tarpaulin can be replaced by a quilt, a net cover and the like according to requirements so as to play a role in insulating temperature or fixing goods in the carriage. Of course, the duvet, the net cover, and the like may be provided inside or outside the awning cloth so as to be unfolded or folded together with the awning cloth.

The utility model can be realized by adopting or using the prior art for reference in places which are not mentioned in the utility model.

The embodiments in the present specification are described in a progressive manner, and the same and similar parts among the embodiments are referred to each other, and each embodiment focuses on the differences from the other embodiments.

The above description is only an example of the present invention, and is not intended to limit the present invention. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
