[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-5A canvas tarpaulin with a multi-cross brace structure includes a canvas body 1, cross brace bodies 2, canvas sleeves 4, fixing cones 5, fixing rings 6, and a positioning mechanism. Multiple cross brace bodies 2 are provided on one side of the canvas body 1, and multiple fixing holes 3 are opened on each cross brace body 2. The canvas sleeves 4 are fitted onto the cross brace bodies 2, and a pin is fixed between the canvas sleeves 4 and the cross brace bodies 2. The fixing cones 5 pass through and slide along the axial direction of the fixing cones 5 in the fixing holes 3. The fixing cones 5 pass through the canvas sleeves 4 and the canvas body 1. The fixing rings 6 are fitted onto the fixing cones 5. The positioning mechanism is provided between the fixing rings 6 and the fixing cones 5 for positioning the fixing rings 6 and the fixing cones 5.

[0033] Reference Figures 2-5 The positioning mechanism includes an annular groove 9, a positioning groove 10, a positioning block 12, and a synchronous rotation mechanism. An annular groove 9 is provided on the fixed cone 5, and multiple positioning grooves 10 are provided on the inner wall of the fixed ring 6. A positioning post 11 is rotatably mounted within each positioning groove 10, and a positioning block 12 is fixedly mounted on each positioning post 11. The synchronous rotation mechanism is mounted on the fixed ring 6 and is used to drive the multiple positioning posts 11 to rotate synchronously. The synchronous rotation mechanism includes a drive groove, a first gear 13, and a drive ring 14. The drive groove is annular and is located on the outer wall of the fixed ring 6. A first gear 13 is rotatably mounted within the drive groove on one side of the positioning post 11. The first gear 13 rotates synchronously with the positioning post 11. A positioning rod is fixedly installed between the positioning posts 11. The driving ring 14 is rotatably installed in the driving groove. A first toothed ring is fixedly installed on the inner wall of the driving ring 14. The first toothed ring meshes with the first gear 13. A torsion spring 15 is fitted on the positioning post 11. The two ends of the torsion spring 15 are fixedly connected to the positioning block 12 and the side wall of the positioning groove 10, respectively. A rubber pad is fixedly installed on the side wall of the positioning block 12. Specifically, after the fixing ring 6 is fitted on the fixing cone 5, the positioning post 11 is driven to rotate under the action of the torsion spring 15, so that the positioning block 12 extends into the annular groove 9, thereby facilitating the fixation between the fixing ring 6 and the fixing cone 5 through the cooperation of the positioning ring and the annular groove 9.

[0034] Reference Figures 3-5 A support ring 7 is provided on one side of the fixing ring 6. The support ring 7 is fitted onto the fixing cone 5. Multiple support springs 8 are fixedly installed between the fixing ring 6 and the support ring 7. After the fixing ring 6 is installed, the support ring 7 can be driven by the elastic force of the support springs 8 to press the canvas body 1 against the surface of the cross brace body 2, thereby improving the fixing stability between the cross brace body 2 and the canvas body 1. At the same time, the positioning block 12 can be pressed against the side wall of the annular groove 9 by the elastic force of the support springs 8, thereby further improving the installation stability between the fixing ring 6 and the fixing cone 5.

[0035] Working principle: In use, the operator places the cross brace body 2 through the canvas sleeve 4 onto the canvas body 1. The operator then passes the cross brace body 2 through the canvas sleeve 4, the fixing port 3, and the canvas body 1. Next, the operator rotates the drive ring 14 on the fixing ring 6. The rotation of the drive ring 14 drives the first toothed ring to rotate, and simultaneously, through the meshing of the first toothed ring with the first gear 13, it drives the first gear 13 and the positioning pin 11 to rotate, thereby moving the positioning block 12 into the positioning groove 10. The operator then places the fixing ring 6 and the support ring 7 onto the fixing cone 5 and releases the drive ring 14. Finally, the operator presses... When the positioning block 12 is aligned with the annular groove 9, the positioning block 12 can extend into the annular groove 9 under the action of the torsion spring 15. Thus, the positioning ring 6 and the fixed cone 5 can be fixed through the cooperation of the positioning ring and the annular groove 9. At this time, the support ring 7 can be driven by the elastic force of the support spring 8 to press the canvas body 1 onto the surface of the cross brace body 2, thereby improving the fixing stability between the cross brace body 2 and the canvas body 1. At the same time, the positioning block 12 can be pressed against the side wall of the annular groove 9 by the elastic force of the support spring 8, thereby further improving the installation stability between the fixed ring 6 and the fixed cone 5.
