[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0023] like Figures 1 to 4 As shown, a portable water conservancy engineering layout display rack includes a storage roll 1. Support rods 4 are rotatably connected to the edges of both ends of the storage roll 1. The bottom end of each support rod 4 has a spike-like structure. A connecting shaft 5 is fixedly connected to the center of the top of the outer side of each support rod 4. Connecting ears 2 are fixedly connected to the top of both ends of the outer wall of the storage roll 1. A fixing shaft 3 is fixedly connected to the center of the top of the outer surface of each connecting ear 2. A tension spring 6 is fixedly connected to the outer walls of the adjacent fixing shaft 3 and connecting shaft 5. The length of the tension spring 6 after reset is less than the length of the adjacent fixing shaft 3 and connecting shaft 5. The distance between them is such that the fixed shaft 3 is located outside the storage roll 1 and higher than the connecting shaft 5. The length of the support rod 4 is adapted to the length of the storage roll 1. The two support rods 4 at one end of the storage roll 1 are in contact with the outer wall of the storage roll 1. The two support rods 4 at the other end of the storage roll 1 are left with a distance equal to the thickness of the support rod 4 between them and the outer wall of the storage roll 1. The inner wall of the storage roll 1 is rolled up and fixedly connected to the display curtain 8. The top of both ends of the outer wall of the storage roll 1 is fixedly connected to an L-shaped blocking frame 7. The L-shaped blocking frame 7 is in contact with the top and one side of the support rod 4. The support rod 4 has a positioning arc structure.

[0024] As an optional technical solution of this utility model: a winding shaft 13 is rotatably connected to the center of the inner wall of the storage roll 1. The display screen 8 is rolled up and fixed to the outer wall of the winding shaft 13. Both ends of the winding shaft 13 are provided with winding springs 14. The center of the winding spring 14 is fixedly connected to the winding shaft 13, and the outer ring of the winding spring 14 is fixedly connected to the inner wall of the storage roll 1. The winding shaft 13 can be automatically driven to retract the display screen 8 by the winding spring 14. At the same time, it can provide tension after the display screen 8 is pulled open.

[0025] As an optional technical solution of this utility model: the width of the display screen 8 is less than the length of the storage roll 1. A pull rod 9 is fixedly connected to the bottom of the display screen 8. The length of the pull rod 9 is greater than the length of the bottom outlet of the storage roll 1. Hooks 12 are fixedly connected to both ends of the pull rod 9. A hanging hole 11 is opened at the center of the bottom of the support rod 4. The position of the hook 12 corresponds to the position of the hanging hole 11 and can be hooked and fixed with the hanging hole 11. Promotional posters can be pasted on the display screen 8. At the same time, after being pulled out, the hook 12 can be hung inside the hanging hole 11 to fix the display screen 8 after it is pulled open.

[0026] As an optional technical solution of this utility model: a lifting handle 10 is fixedly connected to the center of the top of the outer wall of the storage roll 1, and the width of the support rod 4 is smaller than the diameter of the storage roll 1. The storage roll 1 can be easily lifted and carried by the lifting handle 10.

[0027] As an optional technical solution of this utility model: the rotation center of the support rod 4 corresponds to the center of the arc structure at the top of the support rod 4, thereby preventing the top of the support rod 4 from interfering with the inner wall of the L-shaped blocking frame 7 when it rotates.

[0028] The working process of this utility model is as follows: When the user uses it...

[0029] 1) By pulling the support rod 4, it rotates downwards. When the angle between its rotation and the storage drum 1 is greater than 45 degrees, the support rod 4 is quickly extended by the pull of the tension spring 6, so that it can be perpendicular to the storage drum 1.

[0030] 2) The bottom spike structure can be directly inserted into the construction site ground for fixation, thereby supporting the storage roll 1 and allowing the display curtain 8 inside the storage roll 1 to be pulled open for support and display.

[0031] 3) Promotional posters can be pasted on the display screen 8. At the same time, after being pulled out, the hook 12 can be hung inside the hanging hole 11 to fix the display screen 8 after it is pulled out.

[0032] 4) At the same time, when storing, simply pull out the hook 12, and the winding spring 14 will automatically drive the winding shaft 13 to retract the display screen 8. At the same time, simply push the support rod 4, and when its rotation angle with the storage roll 1 is less than 45 degrees, the tension spring 6 will pull the support rod 4 to automatically retract.

[0033] In summary, this utility model, by pulling the support rod 4 downwards, when the angle between its rotation and the storage roll 1 is greater than 45 degrees, is quickly unfolded by the pull of the tension spring 6, making it perpendicular to the storage roll 1. The bottom spike structure allows it to be directly inserted into the ground for fixation, thus supporting the storage roll 1. This allows the display curtain 8 inside the storage roll 1 to be opened for display. Simultaneously, during storage, simply pushing the support rod 4, when the angle between its rotation and the storage roll 1 is less than 45 degrees, causes the support rod 4 to automatically retract by the pull of the tension spring 6. This enables rapid unfolding and retraction, improving the speed of unfolding and storage and increasing the efficiency of carrying and transferring. The L-shaped blocking frame 7 effectively positions the unfolded and retracted positions of the support rod 4, ensuring that it remains vertically positioned and supported when unfolded, and parallel to the storage roll 1 when retracted.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
