[0026] 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.

[0027] Please see Figures 1-3 and Figure 7 This utility model provides a technical solution: an extendable construction protective shed, including: a protective plate 1, a sliding groove 2, an extension plate 3, and support legs 4; the protective plate 1 has a sliding groove 2 inside, the extension plate 3 is slidably connected in the sliding groove 2, the bottom of the extension plate 3 is bolted to the support legs 4, the bottom of the support legs 4 is bolted to the fixed casters 5, the protective plate 1 and the extension plate 3 are provided with limit components 6, and the support legs 4 are provided with reinforcement components 7 on the outside;

[0028] The extendable construction protective canopy can pull the outrigger 4 to drive the extension plate 3 to slide outward from the groove 2, expanding the support area. The fixed caster 5 reduces the friction when the outrigger 4 moves, making it easier to push the fixed caster 5.

[0029] exist Figure 7 In the middle, the limiting component 6 includes a slot 601 opened below the inner wall of the slide groove 2, and an irregular through groove 602 opened on the inner wall of the extension plate 3. A plug rod 603 is slidably connected in the irregular through groove 602, and the plug rod 603 is engaged in the slot 601.

[0030] The extendable construction protective canopy has a rod 603 that is simultaneously inserted into the irregular through groove 602 and the slot 601 to prevent the extension plate 3 from sliding in the slide groove 2.

[0031] exist Figure 7In the middle, a spring 604 is abutted above the insertion rod 603, and the spring 604 abuts against the inner wall of the irregular through groove 602.

[0032] The extendable construction protective canopy has a spring 604 that constantly pushes the insertion rod 603 downward, allowing the insertion rod 603 to be inserted into the slot 601.

[0033] exist Figure 1 , Figure 2 and Figure 7 In the middle, a steel wire rope 605 is connected through the spring 604. The steel wire rope 605 is connected to the upper surface of the insertion rod 603, and the outer side of the steel wire rope 605 abuts against the pulley 606. The pulley 606 is rotatably connected to the inner wall of the irregular through groove 602. The end of the steel wire rope 605 away from the insertion rod 603 is connected to a pull ring 607.

[0034] The extendable construction protective shed has two sets of pulleys 606 to reduce the friction when the wire rope 605 is pulled. The pull ring 607 increases the force-bearing space. Pulling the pull ring 607 drives the wire rope 605 to pull the insert rod 603 upward, and retracts the insert rod 603 into the irregular through groove 602, releasing the restriction on the extension plate 3. Pulling the support leg 4 drives the extension plate 3 to slide. After expanding the space, the pull ring 607 is released, and the spring 604 pushes the insert rod 603 downward to insert into the slot 601, fixing the position of the extension plate 3.

[0035] exist Figure 3 In the middle, a limiting groove 608 is opened at the bottom of the extension plate 3, and a limiting block 609 is slidably connected in the limiting groove 608. The limiting block 609 is connected to the lower inner wall of the slide groove 2 by bolts.

[0036] When the extension plate 3 of the extendable construction protective shed slides in the slide groove 2, the limiting block 609 slides in the limiting groove 608 to limit the extension plate 3 and prevent the extension plate 3 from falling out of the slide groove 2.

[0037] exist Figure 1 In the middle, the reinforcement component 7 includes a support sleeve 701 that is bolted to one side of the support leg 4. A column 702 slides through the support sleeve 701. A handle bolt 703 abuts against the outside of the column 702. The handle bolt 703 is threadedly connected to the inner wall of the support sleeve 701.

[0038] The extendable construction protective shed, after lifting the column 702 and hollow pile 704 from the ground, tightens the handle bolt 703 to press the column 702 into the support sleeve 701, preventing the column 702 from sliding down.

[0039] exist Figure 1 , Figure 2 , Figure 4 and Figure 5In the middle, a hollow pile 704 is fixedly connected to the bottom of the column 702, and a bidirectional threaded rod 705 is rotatably inserted through the hollow pile 704 and the inner wall of the column 702.

[0040] When the wind speed is high and the extendable construction protective shed is easily blown away, holes are drilled in the ground, the column 702 is lowered down, the hollow pile 704 is inserted into the hole, and the column 702 is brought into contact with the ground. Then, the handle bolt 703 is tightened to fix the position of the column 702 and the hollow pile 704, so as to prevent the extendable construction protective shed from moving in the windy environment.

[0041] exist Figure 5 and Figure 6 In the middle, the outer side of the double-threaded rod 705 is threadedly connected to a slip ring 706, the outer side of the slip ring 706 is rotatably connected to a transmission plate 707, and the other end of the transmission plate 707 is rotatably connected to a pressure plate 708, which slides through the inner wall of the hollow pile 704.

[0042] When the double-threaded rod 705 is rotated, it causes two sets of slip rings 706 to slide in opposite directions, pushing the transmission plate 707 to rotate between the slip rings 706 and the pressure plate 708. This pushes the pressure plate 708 outward from the hollow pile 704 and presses it against the inner wall of the hole, preventing the extendable construction protective shed from tipping over in strong winds.

[0043] exist Figure 5 and Figure 6 In the middle, the outer side of the bidirectional threaded rod 705, which is far from the slip ring 706, is connected to a worm gear 709 by a screw. The outer side of the worm gear 709 is engaged with a worm 710, which rotates through the inner wall of the column 702.

[0044] This extendable construction protective shed is self-locking via a worm gear 710 and a worm wheel 709. The worm gear 710 has a hexagonal groove, which can be rotated manually or with an electric screwdriver to drive the worm wheel 709 to rotate. The worm wheel 709 then drives the bidirectional threaded rod 705 to rotate.

[0045] In summary: When using this extendable construction protective shed, first, move the shed to the construction site requiring protection. Depending on the size of the site, pull the pull ring 607 while simultaneously pulling the outrigger 4 to expand the support space. Then, release the pull ring 607 and pull the outrigger 4 again to ensure the extension plate 3 cannot slide. Next, lock the fixed casters 5. If the wind speed is high, the extendable construction protective shed is easily blown away. Drill holes in the ground with an electric drill and loosen the handle bolt 7. After step 03, insert the hollow pile 704 into the hole and abut the column 702 against the ground. Then tighten the handle bolt 703 to fix the position of the column 702 and the hollow pile 704. Then use an electric screwdriver to rotate the worm gear 710, which will drive the pressure plate 708 to press against the inner wall of the hole, fixing the hollow pile 704 in the hole for reinforcement and preventing it from being squeezed against the inner wall of the hole and overturning due to strong winds. The contents not described in detail in this instruction are existing technologies known to those skilled in the art.

[0046] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
