[0028] In order to make the purpose, technical scheme and beneficial technical effects of the utility model clearer and more understandable, the utility model will be further described in detail below in combination with the drawings and specific embodiments. It should be understood that the specific embodiments described in the specification are only for the purpose of explaining the utility model and are not intended to limit the utility model.

[0029] It should also be understood that the terms used in this utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in the utility model specification and the appended claims, the singular forms "a", "an" and "the" are intended to include the plural forms unless the context clearly indicates otherwise.

[0030] It should be further understood that the term "and / or" used in the utility model specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes these combinations.

[0031] In the embodiments of the utility model, a wall hole sealing device 100 is provided for forming a sealed formwork for pouring concrete outside the wall hole 300 of the outer wall 200, and facilitating disassembly without the need for supporting and fixing operations outside the outer wall.

[0032] As Figures 1-4 shown, the wall hole sealing device 100 includes: a first screw 10, a second screw 20, a sleeve 30, a rectangular plate 40, and an expansion plate 50.

[0033] Specifically, the sleeve 30 is a cylindrical tube, and its inner wall is provided with internal threads. The sleeve 30 can be made of plastic, metal or alloy. When the wall hole 300 needs to be blocked, the sleeve 30 is placed in the wall hole 300 and fixed by concrete. The two ends of the sleeve 30 are respectively located on the inner and outer sides of the outer wall 200. After the concrete solidifies, the sleeve 30 is embedded in the concrete, and the two ends can be used as the entrance and exit of the air conditioning pipe, network cable and other pipes that need to pass through the outer wall 200. The two ends can also be closed by a plunger, concrete or the like.

[0034] The first screw rod 10 is screwed to one side of the sleeve 30, and the second screw rod 20 is screwed to the side of the sleeve 30 away from the first screw rod 10. That is, the first screw rod 10 and the second screw rod 20 respectively extend from the two ends of the sleeve 30.

[0035] The rectangular plate 40 is fixed to the end of the first screw rod 10 away from the sleeve 30, forming a kind of umbrella-like structure. In this embodiment, the rectangular plate 40 is a square plate. The first screw rod 10 is vertically fixed to the geometric center of the rectangular plate 40.

[0036] The extension plate 50 is arranged around the rectangular plate 40, forming a larger rectangle that can be folded to a certain extent. Specifically, the extension plate 50 includes four trapezoidal plates 51. As known to all, each trapezoidal plate 51 includes two parallel sides of different lengths and two oblique sides respectively connecting the two ends of the two parallel sides. The two oblique sides of each trapezoidal plate 51 are respectively connected to two adjacent trapezoidal plates 51, for example, the adjacent trapezoidal plates 51 are movably connected by a rabbet hinge structure 52, that is, the connection is a rabbet structure, and a conventional hinge is provided for connection, so that the trapezoidal plates 51 can be deformed and the sealing of the joint can be ensured to prevent slurry leakage.

[0037] The shorter parallel edges of the trapezoidal plates 51 are movably connected to one edge of the rectangular plate 40, so that the four longer parallel edges of the four trapezoidal plates 51 together enclose a larger rectangle relative to the rectangular plate 40. Further, the outer side of the trapezoidal plate 51 extends at least 5 cm relative to the edge of the wall hole 300. That is, the area of the plane formed by the trapezoidal plates 51 and the rectangular plate 40 is larger than the area of the wall hole 300, while the area of the rectangular plate 40 is smaller than the area of the wall hole 300, so that when the rectangular plate 40 passes through the wall hole 300, the expansion plate 50 is resisted by the inner wall of the wall hole 300 and is folded inward to form an umbrella-shaped structure, and after completely passing through the wall hole 300, the expansion plate 50 automatically expands to form a sealing formwork that fits the outer wall of the outer wall 200. It should be noted that the inner side of the outer wall 200 can be closed by a conventional sealing formwork, so that the sealing formworks on the inner and outer sides form a cavity structure for concrete pouring. Of course, the sealing formwork on the inner side of the wall 200 is also provided with a avoiding hole for the second screw 20 to pass through. After the concrete blocks the wall hole 300 and solidifies, the first screw 10 and the second screw 20 are respectively screwed out from both ends of the sleeve 30, so that the two end structures can be taken out, which is simple and convenient to operate.

[0038] Further, the trapezoidal plates 51 and the rectangular plate 40 are movably connected by a press-type hinge (not shown in the figure). It should be noted that the "press-type hinge" is a common hardware, which is mainly used to connect and support two plate structures to enable them to open and close. Its characteristic is that one of the plates can be opened or closed by pressing without additional handles or handles. The press-type hinge includes a base (fixed to the rectangular plate 40, usually with screw holes for fixation), a hinge arm (a rotatable part connecting the base and the trapezoidal plate 51, enabling the trapezoidal plate 51 to open and close), a pressing device (located on the hinge arm, provided with a spring and other components, enabling the trapezoidal plate 51 to pop out or close by pressing), a connecting piece (fixed to the trapezoidal plate 51, connected to the hinge arm), etc. When the expansion plate 50 is pressed, the spring of the pressing device is compressed, so that the expansion plate 50 is folded. When the rectangular plate 40 passes through the wall hole 300, the pressure disappears, the spring releases the elastic potential energy, the expansion plate 50 expands, and finally the rectangular plate 40 and the expansion plate 50 form a flat structure to block the outer side of the wall hole 300.

[0039] In the present embodiment, the rectangular plate 40 and the expansion plate 50 are both aluminum alloy plates.

[0040] Further, in some embodiments, the outer wall of the sleeve 30 is provided with a water stop wing ring 31. The water stop wing ring 31 is annular and is fixed to the outer wall of the sleeve 30 in a circumferential direction to form a protruding structure. In the present embodiment, the water stop wing ring 31 is vertically arranged at the midpoint of the sleeve 30. When the sleeve 30 is embedded in the solidified concrete, the water stop wing ring 31 can effectively prevent external rainwater and other liquids from penetrating from the outside of the wall to the inside of the wall through the gap between the sleeve 30 and the concrete.

[0041] In summary, the wall hole plugging device 100 provided by the utility model, referring to the invention structure of umbrella principle, when the rectangular plate 40 passes through the wall hole 300, the expansion plate 50 is resisted by the inner wall of the wall hole 300 and is inwards folded, and after passing through the wall hole 300 completely, it is automatically unfolded to form a plane with the rectangular plate 40 to seal the outside of the wall hole 300, forming an outer sealing formwork, without the operation of the operating personnel outside the outer wall 200, the safety is improved. When the inner side of the outer wall 200 is also sealed by the formwork, the concrete is poured into the wall hole 300 for plugging, and after solidification, the first screw rod 10 and the second screw rod 20 are screwed out of the sleeve 30 to take out the structure at both ends, at this time, the sleeve 30 is buried in the wall hole 300, the process is simple, and the operation is simple.

[0042] The utility model is not limited to the description in the specification and embodiments, therefore, for those skilled in the art, other advantages and modifications can be easily realized, therefore, the utility model is not limited to specific details, representative equipment and the drawing examples shown and described here without departing from the spirit and scope of the general concept defined by the claims and equivalent range.
