[0023] The application will be further described below in conjunction with specific drawings. In the description of the embodiments, unless otherwise stated, the terms "left", "right", and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the application and simplifying the description, and therefore cannot be understood as indicating or implying that the application must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the application.
[0024] As Figures 1-4 shown, the hole protection device provided by the utility model mainly comprises a support rod 100 and a plurality of baffles 200. The support rod 100 is provided with a preset length and is in a long cylindrical structure. In the embodiment, the support rod 100 is composed of a metal tube to increase its support strength. The plurality of baffles 200 are movably connected with the support rod 100, and a fold is arranged between adjacent two baffles 200 for folding and storing the baffles 200. Specifically, as Figure 1 and Figure 2 shown, the fold comprises a first fold 201 and a second fold 202, and the extension lines of the straight lines where the first fold 201 and the second fold 202 are located intersect at a first center point. The first center point is located on the central axis of the support rod 100, so that the plurality of baffles 200 can be better folded. It should be particularly pointed out that the folding directions of the first fold 201 and the second fold 202 on the same baffle 200 are opposite, so as to ensure that adjacent two baffles 200 can be folded to make the entire device form a smaller volume after being folded, thereby facilitating storage. That is, when the first fold 201 is folded inward, the second fold 202 is folded outward, and when the first fold 201 is folded outward, the second fold 202 is folded inward. In the embodiment, folding inward means that the fold is close to one side of the support rod 100, and folding outward means that the fold is away from one side of the support rod 100. When the baffles 200 are supported open, the plurality of baffles 200 can form a support surface, and the support surface covers the hole entirely, as Figure 4 shown. In the embodiment, when the plurality of baffles 200 are supported open, the plurality of baffles 200 are located on the same horizontal plane. In the embodiment, in order to facilitate storage and reduce the weight of the baffles 200, the baffles 200 are made of transparent acrylic plates. The transparent acrylic plates can also facilitate construction personnel to identify the size of the hole, thereby avoiding the construction personnel from stepping on the hole or the edge of the hole.
[0025] Alternatively, if the weight and cost of the baffles 200 are not considered, the baffles 200 can also be composed of relatively thin steel plates or iron plates.
[0026] In the present application, by adopting the above structure, the protection device can be stored for multiple uses, thereby reducing the cost and avoiding the generation of construction waste. Meanwhile, it is convenient for construction personnel to operate and install.
[0027] In one embodiment, in order to meet the folding requirements between multiple baffles 200, while also improving the connection strength between adjacent baffles 200, hinges 203 are arranged at the folding seams of the baffles 200, wherein the hinges 203 are metal structures, and a proper number of hinges 203 are installed according to the length of the folding seam. It needs to be particularly pointed out that the folding directions of the hinges 203 at the two sides of the same baffle 200 are opposite, thereby ensuring that the baffle 200 can be folded into a smaller volume when being folded and stored.
[0028] In one embodiment, in order to fix the position of the multiple baffles 200 relative to the hole when being supported open, a positioning hole group is arranged on the multiple baffles 200, the positioning hole group includes multiple first positioning holes 204, and an appropriate positioning pin 301 is arranged on the first positioning hole 204, wherein the positioning pin 301 is detachable relative to the first positioning hole 204. When the positioning pin 301 is fixed on the first positioning hole 204, the positioning pin 301 protrudes relative to the baffle 200, as shown in Figure 2 At this time, the protruding part of the positioning pin 301 can abut against the edge of the high-efficiency air port, thereby fixing the relative position of the baffle 200 and the high-efficiency air port, and fixing the relative position of the protection device formed by the baffle being supported open relative to the high-efficiency air port, thereby ensuring that the high-efficiency air port is always covered by the protection device.
[0029] In the present embodiment, the positioning hole group includes multiple first positioning holes 204, the first positioning holes 204 are designed at intervals from the support rod 100 to the periphery of the baffle 200, and the number of the positioning pins 301 is determined according to the number of edges of the protection device. In the present embodiment, the number of edges of the protection device is 4, and the number of the positioning pins 301 is 4. The 4 positioning pins 301 abut against the 4 edges of the high-efficiency air port. By arranging the above-mentioned positioning hole group, the positioning pin 301 can be inserted according to the size of the high-efficiency air port.
[0030] In one embodiment, in order to avoid the positioning pin 301 from falling off, the operator finds the positioning pin 301 during installation, and a fixing rope 302 arranged on the support rod 100 is further included. One end of the fixing rope 302 is fixedly connected to one end of the support rod 100, and the other end of the fixing rope 301 is fixedly connected to the positioning pin 301, thereby ensuring that the positioning pin 301 is always connected with the support rod 100, and avoiding the positioning pin 301 from falling off. In the present embodiment, the number of the fixing ropes 302 matches the number of the positioning pins 301, and the fixing rope 302 is arranged with a certain length, which can ensure that the positioning pin 301 is inserted into the first positioning hole 204 close to the edge of the baffle 200.
[0031] Further, in order to facilitate the construction personnel to see the protection device formed by the baffle 200, a warning sign is arranged on the fixing rope 302. Specifically, the warning sign can be a warning flag or a reflective strip, or a cloth strip of a more eye-catching color, so that the construction personnel can see it and avoid stepping on the protection device arranged on the high-efficiency air inlet, on the one hand to avoid damage to the device, and on the other hand to avoid injury from falling from the air inlet.
[0032] In one embodiment, since the baffle 200 is expanded to form a planar state covering the hole, in order to ensure that the protection device composed of the baffle 200 remains in a planar state in the expanded state, a fixed baffle edge 101 is arranged at one end of the support rod 100, as shown in the figure. Figure 2 When the plurality of baffles 200 are expanded to form a planar structure, the plurality of baffles 200 are all in abutment with the fixed baffle edge 101. The protection device formed by the plurality of baffles 200 will not collapse towards the lower side of the hole, thereby avoiding the protection device from falling from the hole.
[0033] Further, in order to realize the movable connection between the baffle 200 and the support rod 100, as shown in the figure, a fixed ring 102 is arranged on the support rod 100, the fixed ring 102 is sleeved on the support rod 100, the plurality of baffles 200 are hinged with the fixed ring 102, and the fixed ring 102 moves relative to the axial direction of the support rod 100, thereby realizing the synchronous folding and unfolding of the plurality of baffles 200. Figure 3 Further, in order to realize the movable connection between the baffle 200 and the support rod 100, as shown in the figure, a fixed ring 102 is arranged on the support rod 100, the fixed ring 102 is sleeved on the support rod 100, the plurality of baffles 200 are hinged with the fixed ring 102, and the fixed ring 102 moves relative to the axial direction of the support rod 100, thereby realizing the synchronous folding and unfolding of the plurality of baffles 200.
[0034] Further, a guide bevel 1031 is arranged on the elastic buckle 103. When the plurality of baffles 200 are changed from the folded state to the support state, the fixed ring 102 can extrude the elastic buckle 103 through the guide bevel 1031, so that the elastic buckle 103 is retracted into the support rod 100, thereby enabling the fixed ring 102 to pass through the elastic buckle 103 and abut against the fixed baffle edge 101. By arranging the guide bevel 1031, the construction personnel only need to push the fixed ring 102 to slide along the axis of the support rod 100 during operation, without the need to press the elastic buckle 103, thereby facilitating the operation.
[0035] In one embodiment, the number of the baffles 200 is 8, each baffle 200 is a right triangle structure, and each baffle 200 is of the same size, and in the expanded state, as shown in Figure 4 Fig. 8, the baffles 200 can form a square structure. Alternatively, the number of the baffles 200 is at least 4, and the four triangles form a rectangle when expanded.
[0036] The above description is only preferred embodiments of the present application, and it should be pointed out that, for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made. These improvements and refinements should also be considered within the scope of the present application.
