The driving member is a prior art, generally a motor, and the power output end of the motor is connected to the central rod 5;

[0029] Both ends of the center rod 5 are fixed with connecting tubes 10, the right end of the left connecting tube 10 is fixed to the left end of the center rod 5, and the left end of the right connecting tube 10 is fixed to the right end of the center rod 5. The two connecting tubes 10 are installed in the corresponding fixing plates 6. The right side wall of the left fixing plate 6 is provided with a blind hole to the left, and a bearing is installed in the blind hole. The left end of the left connecting tube 10 is fixed in the inner ring of the bearing, and the left side wall of the right fixing plate 6 is provided with a blind hole to the right, and a bearing is installed in the blind hole. The right end of the right connecting tube 10 is fixed in the inner ring of the bearing; the connecting tubes 10 are provided with through grooves that communicate with each other from top to bottom, and a sliding rod 11 is vertically and independently installed in the through groove. The through groove is provided on the upper tube wall of the connecting tube 10, and the sliding rod 11 is vertically installed in the through groove and slides up and down along the through groove; the upper end of the sliding rod 11 is horizontally fixed with a first clamping plate 9, such as Figure 3As shown, the left end of the first clamping plate 9 is fixed to the upper end of the sliding rod 11; a tension spring 12 is installed between the lower end of the sliding rod 11 and the inner bottom of the connecting tube 10, the upper end of the tension spring 12 is fixed to the lower end of the sliding rod 11, and the lower end of the tension spring 12 is fixed to the inner bottom of the connecting tube 10; in the natural state of the tension spring 12, the bottom of the first clamping plate 9 presses the top corner of the tarpaulin 8 onto the center rod 5, and under the action of the tension spring 12, the sliding rod 11 is pulled downward, the first clamping plate 9 is pulled toward the center rod 5, and the tarpaulin 8 is clamped on the outside of the center rod 5; this paragraph of text as a whole constitutes a downward The pulling assembly of the sliding rod 11 is used. When the pulling assembly is used, when the first clamping plate 9 is pulled away from the outside of the central rod 5, the sliding rod 11 moves upward, and the tension spring 12 is deformed by force. After the tarpaulin 8 is placed between the first clamping plate 9 and the central rod 5, the first clamping plate 9 is released, and the tension spring 12 loses the force and recovers the deformation, and the sliding rod 11 is pulled downward to clamp the tarpaulin 8 on the central rod 5; of course, the pulling assembly is vertically fixed with a vertical tube 14 at the bottom of the connecting tube 10, and the sliding rod 11 is vertically and independently installed in the vertical tube 14, and the vertical tube 14 plays a guiding role on the sliding rod 11, so that the sliding rod 11 The rod 11 can only slide along the length direction of the vertical tube 14 to prevent the sliding rod 11 from deviating when moving; this paragraph of text as a whole constitutes a clamping assembly for clamping the left and right corners of the tarpaulin. When the clamping assembly is used, the first clamping plate 9 is pulled upward to make the first clamping plate 9 leave the surface of the center rod 5, and a gap for placing the tarpaulin 8 is formed between the first clamping plate 9 and the center rod 5. The corner of the tarpaulin 8 is placed in the gap, and the sliding rod 11 is pulled downward by the pulling assembly to clamp the corner of the tarpaulin 8 on the center rod 5 through the first clamping plate 9; of course, in the clamping assembly, the first clamping plate 9 The thickness is 1cm-2cm. The first plywood 9 clamps the corners of the tarpaulin 8. When the tarpaulin 8 is rolled up, the tarpaulin 8 will be wrapped around the outside of the first plywood 9. The thickness of the first plywood 9 will directly affect the rolling effect of the tarpaulin 8. If the thickness of the first plywood 9 is too thick, the two sides of the tarpaulin 8 will be padded during the rolling process, affecting the subsequent storage of the tarpaulin 8. If the thickness of the first plywood 9 is too thin, it will affect the structural strength of the plywood 9, resulting in the inability to clamp the corners of the tarpaulin 8. The thickness of the first plywood 9 can be selected as any value between 1cm, 1.5cm, 2cm, and 1cm-2cm.

[0030] A groove is opened upward at the bottom of the horizontal plate 1, and a slider 4 is independently installed in the groove, and the slider 4 slides up and down along the depth direction of the groove; a push plate 2 is horizontally fixed to the bottom of the slider 4, and a spring 3 is arranged between the top of the slider 4 and the bottom of the groove, the upper end of the spring 3 is fixed to the bottom of the groove, and the lower end is fixed to the top of the slider 4; in the natural state of the spring 3, the push plate 2 pushes the tarpaulin 8 to be pressed against the center rod 5, and under the action of the spring 3, when the tarpaulin 8 is rolled up, the tarpaulin 8 is pushed and pressed against the center rod 5 by the push plate 2, so that the tarpaulin 8 can be tightened on the center rod 5; this paragraph of text as a whole constitutes a pressing component that presses the tarpaulin 8 against the center rod 5; of course, in the pressing component, the length of the push plate 2 is equal to the length of the center rod 5, and when the tarpaulin 8 is rolled up, the tarpaulin 8 is pressed against the center rod 5 by the push plate 2.

[0031] When this embodiment is used, one end of the tarpaulin 8 is extended into the center rod 5 from between the two fixing plates 6, and the two top corners of the tarpaulin 8 are pressed against the center rod 5 by the clamping assembly. The center rod 5 is driven to rotate by the driving member to roll up the tarpaulin 8 on the center rod 5. During the rolling process of the tarpaulin 8, the tarpaulin 8 is pressed against the center rod 5 by the pressing assembly, so that the tarpaulin 8 can be tightened on the center rod 5, thereby reducing the floor space occupied by the tarpaulin 8, replacing manual rolling of the tarpaulin 8, and reducing labor intensity.

[0032] Example 2

[0033] This embodiment further illustrates the technology. Figure 4 As shown, a limit plate 13 is horizontally fixed on the slide bar 11 above the vertical tube 14, and the slot width of the through slot is smaller than the width of the limit plate 13. The limit plate 13 limits the slide bar 11 to prevent the slide bar 11 from moving up too much and slipping out of the through slot, thereby ensuring the stability of the slide bar 11 when moving.

[0034] like Figure 2 and Figure 3 As shown, the first clamping plate 9 is an arc-shaped plate structure with its opening facing downward. The first clamping plate 9 with an arc-shaped structure presses the tarpaulin 8 and then fits against the outer side of the central rod 5. When the tarpaulin 8 is rolled up, the tarpaulin 8 is wrapped around the outer side of the first clamping plate 9, and the first clamping plate 9 with an arc-shaped structure does not affect the rolling up of the tarpaulin 8.

[0035] like Figure 1 and Figure 2 As shown, the push plate 2 is an arc-shaped plate structure with its opening facing downward, and the lower end of the push plate 2 is an arc-shaped structure, so that the lower end of the push plate 2 is more closely attached to the center rod 5, which is beneficial to the rolling up of the tarpaulin 8.

[0036] Example 3

[0037] This embodiment further illustrates the technology. Figure 1 and Figure 2As shown, second clamping plates 7 are horizontally fixed on adjacent side walls of the two fixing plates 6. There are two second clamping plates 7. The left end of the left second clamping plate 7 is fixed on the right side wall of the left fixing plate 6, and the right end of the right second clamping plate 7 is fixed on the left side wall of the right fixing plate 6.

[0038] The second clamping plate 7 is provided with a front-to-back connecting groove, the right side wall of the left second clamping plate 7 is provided with a front-to-back connecting groove to the left, and the left side wall of the right second clamping plate 7 is provided with a front-to-back connecting groove to the right, and the width of the groove is slightly greater than the thickness of the tarpaulin 8;

[0039] The end of the tarpaulin 8 is inserted into the chute in the second clamping plate 7 and then rolled up on the central rod 5. The tarpaulin 8 is flattened when passing through the chute to prevent wrinkles from being generated when the tarpaulin 8 is rolled up on the central rod 5, thereby extending the service life of the tarpaulin 8.

[0040] In this embodiment, the second clamping plate 7 can also use pressure rollers. Two pressure rollers are installed on the right side wall of the left fixed plate 6. The two pressure rollers are horizontally distributed front and back. Two pressure rollers are installed on the left side wall of the right fixed plate 6. The two pressure rollers are horizontally distributed front and back. A gap is left between the two pressure rollers on the same side for the tarpaulin 8 to pass through. The two ends of the tarpaulin 8 pass through the gap between the pressure rollers and are rolled up on the center rod 5.

[0041] Example 4

[0042] This embodiment further illustrates the technology. Figure 5 As shown, the tarpaulin 8 includes base fibers 18, which are staggered and connected to form a grid structure. A wear-resistant layer 15 is arranged on the outside of the tarpaulin 8. The outside of the base fibers 18 is wrapped with silica sol. The base fibers 18 are immersed in the silica sol before being staggered and connected, so that the silica sol is wrapped on the outside of the base fibers 18 to form composite fibers. The porous properties and compressible gradient effect of the silica gel itself make the treated composite fibers have extremely strong absorption properties for high-intensity impact forces, thereby improving the strength of the tarpaulin 8.

[0043] like Figure 5 As shown, a surface layer 17 is provided between the base fiber 18 and the wear-resistant layer 15. The surface layer 17 is made of silica aerogel and low-density polyethylene, which are processed, melt-plasticized and extruded by a coating machine, and then coated on the grid-structured composite fiber. The surface layer improves the waterproofness, thermal insulation and aging resistance of the tarpaulin 8.

[0044] like Figure 5 As shown, a flame retardant layer 16 is provided between the wear-resistant layer 15 and the surface layer 17. When a fire occurs outside and ignites the wear-resistant layer, the flame retardant layer 16 prevents the fire from spreading to the tarpaulin, so that the fire stops burning due to lack of combustibles, thereby improving the fire resistance of the tarpaulin.
