DETAILED DESCRIPTION

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] like Figures 1-4 As shown, the military truck tarpaulin includes a tarpaulin body 1. In this embodiment, the tarpaulin body 1 adopts an existing product; a retractable bracket assembly is connected to the tarpaulin body 1, and the retractable bracket assembly includes a plurality of support rods 6. The tarpaulin body 1 is connected to the support rods 6. The sides of the support rods 6 are connected to guide blocks 5. A regulating cross bar 8 is provided between adjacent guide blocks 5. The regulating cross bar 8 is connected to one of the guide blocks 5. The regulating cross bar 8 is slidably connected to the guide groove portion 5c of the other guide block 5. The other guide block 5 also has a limiting groove portion 5b, and the regulating cross bar 8 has a limiting block 10 that matches the limiting groove portion 5b. The other guide block 5 is also equipped with a mounting seat 9, and a spring plunger 11 is installed on the mounting seat 9. A card hole 8a that matches the spring plunger 11 is provided on the regulating cross bar 8. The end of the support rod 6 is connected to the tarpaulin body 1 The fork block 2 is equipped with an auxiliary guide wheel 3. With this structure, when it is necessary to unfold, the outermost guide block 5 is pulled outward. With the cooperation of the regulating cross bar 8 and the auxiliary guide wheel 3, the support rods 6 are translated and eventually the support rods 6 are moved away from each other, thereby unfolding the tarpaulin body 1; when it is necessary to fold, the outermost guide block 5 is pushed inward. With the cooperation of the regulating cross bar 8 and the auxiliary guide wheel 3, the support rods 6 are translated and eventually the support rods 6 are moved close to each other, thereby folding the tarpaulin body 1. At this time, the ball of the spring plunger 11 can be stuck in the card hole 8a, which plays an auxiliary positioning role; in this embodiment, the auxiliary guide wheel 3 cooperates with the car body of the truck through the existing technology, that is, the auxiliary guide wheel 3 can roll horizontally on the car body, and the auxiliary guide wheel 3 can be prevented from being separated from the car body by the limiting pin 4, which also adopts the existing technology.

[0018] The support rod 6 is U-shaped.

[0019] The outermost guide block 5 has a handle groove 5a.

[0020] A limiting pin 4 is also installed at the end of the support rod 6.

[0021] The tarpaulin body 1 is connected to the support rods 6 via a plurality of fixing members 7 .

[0022] In the present invention, the telescopic bracket assembly cooperates with the tarpaulin body 1 so that the tarpaulin body 1 can be expanded or folded as needed.

[0023] The above components are all common standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0024] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
