[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. 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.
[0024] Please see Figures 1-4 In this embodiment of the utility model, a protective device for building engineering includes a first support column 1 and a second support column 2. The first support column 1 and the second support column 2 are connected to multiple sets of movable columns 4 by cross rods 3. The bottom ends of the first support column 1 and the second support column 2 are respectively welded with a first support plate 5 and a second support plate 6. The side of the first support column 1 is fixedly installed with two sets of upper and lower first splicing blocks 7. The side of the second support column 2 is fixedly installed with two sets of second splicing blocks 8 corresponding to the first splicing blocks 7. Each set of second splicing blocks 8 is equipped with a buckle assembly for connecting the first splicing blocks 7.
[0025] When in use, the operator pulls the first support column 1 and the second support column 2 in the opposite direction. The first support column 1 and the second support column 2 drive the cross bar 3 to rotate, and the cross bar 3 drives the movable column 4 to move. Adjusting the distance between the movable columns 4 allows for easy control of the enclosure length of the protective device. The unfolded protective device can enclose dangerous areas during construction. The first splicing block 7 and the second splicing block 8 facilitate the assembly and use of two adjacent sets of protective devices. The snap-fit components facilitate quick connection between the devices.
[0026] Among them, the movable column 4, the first support column 1 and the second support column 2 are each provided with a fixed node 9 and a movable node 10 that are rotatably connected to the end of the cross bar 3. The movable column 4, the first support column 1 and the second support column 2 are provided with a connecting groove 11 for the movable node 10 to slide up and down. Pulling the first support column 1 and the second support column 2 can move the movable node 10 connected to the cross bar 3, which can facilitate the adjustment of the protective device.
[0027] In one embodiment, the latching assembly includes a first spring 12 connected to the second splicing block 8. A baffle 13 is connected to the end of the first spring 12. A rod 14 that passes through the second splicing block 8 is welded onto the baffle 13. The rod 14 can slide up and down inside the second splicing block 8.
[0028] Pulling the baffle 13 moves the insert rod 14. After the first splicing block 7 and the second splicing block 8 are connected, the insert rod 14 is inserted into the interior of the first splicing block 7, which facilitates the quick assembly of the two sets of protective devices. The first spring 12 provides support for the insert rod 14. Both sets of baffles 13 are connected to the same pull plate 16 through the movable rod 15. The end of the movable rod 15 is rotatably connected to the baffle 13 and the pull plate 16 through the pin. Pulling the pull plate 16 moves the movable rod 15, and the movable rod 15 moves the baffles 13, which can facilitate the simultaneous opening and closing of the two sets of buckle components.
[0029] Furthermore, an L-shaped fixing plate 17 is welded to the front of the second support column 2, and two sets of tie rods 18 are welded to the side of the pull plate 16, which pass through the L-shaped fixing plate 17. The tie rods 18 can slide inside the L-shaped fixing plate 17. The ends of the two sets of tie rods 18 are connected to the same movable plate 19. Pulling the tie rods 18 will move the pull plate 16. The L-shaped fixing plate 17 provides support for the tie rods 18, which can improve the stability of the upper and lower sets of insertion rods 14. A second spring 20 is installed between the L-shaped fixing plate 17 and the pull plate 16 and sleeved on the outside of the tie rods 18, which can facilitate the automatic snap-locking and reset of the insertion rods 14.
[0030] In one embodiment, a connecting rod 21 is rotatably mounted on the top of the first support plate 5, and a fixing knob 22 is threadedly connected to the end of the connecting rod 21. Positioning holes 23 corresponding to the fixing knob 22 are provided on both the first support plate 5 and the second support plate 6.
[0031] When the fixing knob 22 on the connecting rod 21 is threaded to the positioning hole 23 on the first support plate 5, it can prevent the connecting rod 21 from rotating arbitrarily. When the protective device is folded and stored, the fixing knob 22 at the end of the connecting rod 21 is installed into the positioning hole 23 on the second support plate 6, which can prevent the protective device for construction projects from being scattered during transportation. The bottom of the first support plate 5 and the second support plate 6 are both equipped with two sets of universal wheels 24, which can facilitate the movement of the protective device for construction projects.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
