Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-5 An embodiment of this utility model provides a foldable temporary sunshade for construction, including a sunshade canvas 1. A side block 2 is fixedly installed on one side of the sunshade canvas 1, and a side block 3 is provided on the other side of the sunshade canvas 1. Rotating seats 7 are symmetrically fixedly installed at the front and rear ends of the side blocks 1 2 and 2 3 respectively. Support brackets 4 are rotatably provided below each of the four rotating seats 1 7. Telescopic rods 16 are symmetrically provided at the front and rear ends between the side blocks 1 2 and 2 3 respectively. One end of the telescopic rod 16 contacts the side block 2 3, and a rotating seat 2 15 is rotatably installed at the other end of the telescopic rod 16. Both the rotating seats 1 7 and the rotating seat 2 15 are U-shaped plates, and the rotating seat 2 15 is fixedly connected to the side block 1 2.

[0025] The support bracket 4 can be rotated and extended via the rotating seat 7, while the telescopic rod 16 can be flexibly adjusted in length and rotated, allowing the entire sunshade to be folded and retracted, greatly reducing the space occupied during transportation and storage, thereby reducing handling costs and difficulties, and improving the portability and practicality of the sunshade.

[0026] Please see Figure 2 and Figure 3 The support bracket 4 includes a telescopic strip 401 and a fixed square tube 402. The telescopic strip 401 is positioned above the fixed square tube 402. The lower end of the telescopic strip 401 slides into the interior of the fixed square tube 402. The upper end of the telescopic strip 401 is rotatably connected to the rotating seat 7. Elongated slots 4021 are symmetrically arranged on both end faces of the fixed square tube 402. Fixing bolts 9 are installed inside the fixed square tube 402. The fixed square tube 402 and the telescopic strip 401 are fixedly connected by fixing bolts 9. The screw head of the fixing bolt 9 is located on one side of the fixed square tube 402. The screw end of the fixing bolt 9 passes through the elongated slot 4021 and slides through the lower end of the telescopic strip 401 before extending to the other side of the fixed square tube 402. A nut is threaded on the outer side of the screw end of the fixing bolt 9, so that the telescopic strip 401 and the fixed square tube 402 can be stably connected.

[0027] By loosening the fixing bolts 9, the telescopic strip 401 can be raised and lowered, thereby adjusting the overall height of the support bracket 4. This allows the awning to be adjusted according to actual needs, adapting to different construction scenarios. At the same time, the adjustment method is simple and quick, requiring only the loosening of the fixing bolts to raise and lower it. This also facilitates further reduction in volume when folding, increasing practicality.

[0028] Please see Figure 2A pad 8 is fixedly installed on the lower outer side of the fixed square tube 402, and the pad 8 has multiple through holes inside.

[0029] The pad 8 enhances the stability of the support bracket, and the through-hole structure facilitates fixing with ground nails or counterweights, improving wind resistance and ensuring safety in severe weather.

[0030] Please see Figure 1 and Figure 5 The interior of the second side block 3 is provided with a cavity. A winding rod 13 is rotatably installed inside the cavity of the second side block 3. One end of the sunshade canvas 1 extends into the cavity of the second side block 3 and is fixedly installed on the outside of the winding rod 13. A rotating cap 14 is provided at the front end of the second side block 3. The front end of the winding rod 13 extends to the front end of the second side block 3 and is fixedly connected to the rotating cap 14.

[0031] When the sunshade is not needed, the sunshade canvas 1 is rolled up into the cavity of the side block 3 by rotating the rotating cap 14 to drive the winding rod 13. The rolled-up sunshade canvas 1 is better protected and avoids damage from wind, sun and rain erosion caused by long-term exposure, thus extending the service life of the sunshade canvas. When the sunshade is needed, simply rotate the rotating cap 14 in the opposite direction to unfold the sunshade canvas 1.

[0032] Please see Figure 1 and Figure 4 A fixing plate 5 is symmetrically fixedly installed at the front and rear ends of the upper part of side block 2. The fixing plate 5 has a threaded hole inside. A rotating plate 6 is symmetrically installed at the front and rear ends of the upper part of side block 3. A rotating shaft 10 is fixedly installed inside the rotating plate 6. The rotating shaft 10 passes through the rotating plate 6 and is rotatably connected to side block 3. A bottom groove is provided at one end of the rotating plate 6. A threaded rod 11 is threadedly installed inside the rotating plate 6 along the upper part of the bottom groove. The upper end of the threaded rod 11 extends to the upper part of the rotating plate 6 and is fixedly installed with a handwheel 12. After the temporary sunshade is folded, by rotating one end of the rotating plate 6 to the upper part of the fixing plate 5, the threaded rod 11 is aligned with the threaded hole. Then, the handwheel 12 is rotated so that the lower end of the threaded rod 11 is screwed into the threaded hole of the fixing plate 5, which increases the stability of the two side blocks after folding.

[0033] Side block 1 (2) and side block 2 (3) are locked after folding through a fixing plate (5), a rotating plate (6), a threaded rod (11), and a handwheel (12), preventing the two side blocks from unfolding during transportation and increasing practicality.

[0034] Working principle: When in use, first unfold the folded sunshade, separate side block 1 (2) and side block 2 (3), and rotate the rotating cap 14 in the opposite direction to rotate the retracting rod 13 inside the block cavity, unfolding the sunshade canvas 1 from its retracted state. Rotate the rotating seat 7 to rotate the support bracket 4 to the support position. Since the support bracket 4 consists of a telescopic strip 401 and a fixed square tube 402, connected by fixing bolts 9, loosening the fixing bolts 9 allows the telescopic strip 401 to move up and down within the fixed square tube 402. After adjusting the height of the support bracket 4 according to the actual construction needs, tighten the fixing bolts 9 to secure it. At this time, the pad 8 on the lower outer side of the fixed square tube 402 increases the contact area with the ground, enhancing stability. It can also be further secured with ground nails or counterweights through the through holes on the pad 8, improving wind resistance. The telescopic rod 16 between side block 2 and side block 3 can be flexibly adjusted in length and rotated to assist in supporting the overall shape of the sunshade. After the sunshade is used, loosen the fixing bolt 9 to lower the height of the support bracket 4. Rotate the rotating seat 7 to retract and extend the support bracket 4, and rotate the telescopic rod 16 after it retracts. Then rotate the rotating cap 14 to drive the winding rod 13 to roll up the sunshade canvas 1 into the cavity of side block 3 for protection. Next, rotate the rotating plate 6 on side block 3 around the rotating shaft 10 to the top of the fixing plate 5 on side block 2, so that the threaded rod 11 corresponds to the threaded hole in the fixing plate 5. Rotate the handwheel 12 to screw the lower end of the threaded rod 11 into the threaded hole, lock the position of the two side blocks, and complete the folding of the sunshade. This greatly reduces the space occupied during transportation and storage, reduces the cost and difficulty of handling, and improves portability and practicality.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
