[0025] As shown in Figure 1 The present embodiment discloses a hole sealing device, which can be used to seal a hole 300 that penetrates a wall. The hole sealing device of the present embodiment comprises a connecting strip 100 and two sealing members 200 for sealing two sides of the hole 300. The two sealing members 200 can be sealed at two hole opening positions of the hole 300, and the connecting strip 100 can pull the two sealing members 200 tightly so that the sealing members 200 are stabilized at the hole opening positions.

[0026] As shown in Figure 2 The sealing member 200 of the present embodiment comprises a plug 210, which is configured in a horn shape. The horn-shaped plug 210 has a large port 210a, which faces the hole opening of the hole 300 and covers the hole opening surface of the hole 300, thereby sealing the hole opening. The horn-shaped plug 210 can tightly fit the wall 400, and the leakage of grout can be avoided during the sealing process.

[0027] In the present embodiment, the outer diameter of the large port 210a of the plug 210 is 1.5 to 8 times the inner diameter of the hole 300 to be sealed. In some preferred embodiments, the outer diameter of the large port 210a of the plug 210 is 3 to 5 times the inner diameter of the hole 300 to be sealed.

[0028] As shown in Figure 3 and Figure 4 In the present embodiment, the sealing member 200 further comprises a rigid cylinder 220, which is fixedly connected with the plug 210. The inner circumferential wall of the rigid cylinder 220 is provided with a clamping groove 220a (as shown in Figure 4As shown, the depth direction of the clamping groove 220a is configured as the radial direction of the rigid cylinder 220, and the connecting strip 100 is provided with a clamping tooth 110 which can be clamped in the clamping groove 220a. In this embodiment, the connecting strip 100 is connected with the plug 210 through the rigid cylinder 220, and the material of the rigid cylinder 220 has a certain rigidity (for example, metal material and the like), so that the connection between the connecting strip 100 and the plug 210 is more stable, and the traditional threaded connection mode is cancelled in this embodiment, and a clamping mode is adopted, on the one hand, the processing technology is simplified, and on the other hand, the operation steps can be simplified, and the rapid connection between the connecting strip 100 and the plug 210 is realized. In some preferred embodiments, the depth of the clamping groove 220a is greater than or equal to the thickness of the connecting strip 100 (including the clamping tooth 110), so as to avoid the disengagement of the clamping tooth 110 and the clamping groove 220a of the rigid cylinder 220.

[0029] As shown in the figure, Figure 3 In this embodiment, the center of the plug 210 is provided with a center hole 210b, the center hole 210b is configured as a through hole, the shape of the rigid cylinder 220 is configured as a circular cylinder, and the outer circumferential surface of the rigid cylinder 220 is in close contact and fixedly connected with the inner circumferential wall of the center hole 210b (for example, bonding and the like). The center hole 210b and the rigid cylinder 220 are coaxially arranged, and in some other embodiments, the center hole 210b, the rigid cylinder 220 and the hole to be plugged 300 are coaxially arranged.

[0030] As shown in the figure, Figure 3 In this embodiment, the plugging piece 200 further comprises a hole cover 230, at least a part of the hole cover 230 can be inserted into the rigid cylinder 220, so as to plug the rigid cylinder 220. The function of the hole cover 230 is to close the rigid cylinder 220, so as to avoid the overflow or outflow of the filling material 500 in the hole 300 from the plug 210. In some preferred embodiments, a thin rope 240 (as shown in the figure) is connected between the hole cover 230 and the plug 210, that is, one end of the thin rope 240 is connected with the hole cover 230, and the other end of the thin rope 240 is connected with the plug 210, and the thin rope 240 can connect the hole cover 230 with the plug 210, so as to avoid the loss of the hole cover 230, and the use is convenient. Figure 2

[0031] In this embodiment, the plug 210 is configured of flexible material, so that the plug 210 can easily pass through the hole 300 and extend to the outdoor side. It should be noted that even if the plug 210 of this embodiment is not flexible material (for example, some spring steel and the like), it can also be deformed under the extrusion of the hole 300. In some preferred embodiments, the material of the plug 210 is configured as rubber.

[0032] In this embodiment, the plugging piece 200 has the following advantages: ​

[0033] First, the plug 210 of the present embodiment can ensure the sealing quality of the through-wall hole 300, and the rubber material itself has strong waterproof performance, so that the sealing effect is waterproof after sealing;

[0034] Second, the plug 210 is in a trumpet shape (also known as a mushroom shape) in a natural state. After being installed on both sides of the through-wall hole 300, the plug 210 can be tightly attached to the surface of the wall 400 under the tension of the connecting strip 100, preventing the filling material from leaking out. Even if the filling material has a slight expansion, there will be no leakage. The plugs 210 at both ends can also ensure the filling quality of the hole 300. The flexible plug 210 can act as a buffer and shock absorber, and has the advantages of heat preservation and maintenance.

[0035] As shown in Figure 5 In some preferred embodiments, the connecting strip 100 is in the shape of a long strip, and a plurality of clamping teeth 110 are arranged along the length direction of the connecting strip 100. Any one of the clamping teeth 110 can be clamped together with the clamping groove 220a along the radial direction of the rigid cylinder 220. After being clamped together, the connecting strip 100 cannot move relative to the rigid cylinder 220 and the plug 210 in the axial direction (i.e., the length direction of the hole 300). The plurality of clamping teeth 110 arranged on the connecting strip 100 can separate the two plugs 210 by any distance, facilitating the matching of the plugs 210 to seal the holes 300 on the wall 400 of different thicknesses. In addition, the plurality of clamping teeth 110 located in the middle position of the hole 300 can ensure that the connecting strip 100 is more tightly combined with the filling material, thereby improving the bonding force between the entire device and the wall 400. Moreover, the filling material and the connecting strip 100 work together, which is similar to embedding a through fiber material in the filling material, thereby improving the overall performance of the sealing material.

[0036] In some preferred embodiments, the material of the connecting strip 100 is configured to have a certain rigidity and can be wound together, such as polymeric materials (polyethylene PE, polypropylene PP, polyvinyl chloride PVC, etc.), strip steel (first-grade strip steel, etc.), or ABS plastic (BS new plastic, etc.). The connecting strip 100 is selected to have a certain rigidity, so that it can smoothly pass through the hole 300 with the plug 210 and push the plug 210 out to the outdoor side. In addition, the connecting strip 100 can be wound together like a tape measure (as shown in Figure 6 ), which can be cut for use, thereby being convenient and fast.

[0037] One working mode of the hole sealing device of the present embodiment is as follows:

[0038] Preparation: The worker is located on the indoor side, and the hole 300 to be sealed is cleaned;

[0039] First, the big port 210a of the first plug 210 is directed towards the worker (i.e. towards the indoor side), then the connecting strip 100 is clamped with the first plug 210, and then the rigid cylinder 220 of the first plug 210 is closed with the hole cover 230;

[0040] Second, the big port 210a of the second plug 210 is directed away from the worker, then the connecting strip 100 is passed through the rigid cylinder 220 inside the second plug 210 (at this time, the connecting strip 100 and the rigid cylinder 220 of the second plug 210 are not clamped together), thus forming the opposite structure of the big ports 210a of the two plugs 210, and then the two plugs 210 are separated along the length direction of the connecting strip 100 by a distance greater than the thickness of the wall 400;

[0041] Third, the worker holds the connecting strip 100 on the indoor side, inserts the first plug 210 into the hole 300 (the small port of the first plug 210 is directed towards the outdoor side), and pushes the first plug 210 out to the outdoor side of the hole 300 through the connecting strip 100, then pulls the connecting strip 100 back, and when resistance is encountered, it proves that the big port 210a of the first plug 210 is tightly pressed against the surface of the outdoor wall 400;

[0042] Fourth, the second plug 210 is pushed along the length direction of the connecting strip 100 so that its big port 210a is pressed against the wall surface on the indoor side, then the clamping teeth 110 on the connecting strip 100 are clamped into the clamping groove 220a of the rigid cylinder 220 of the second plug 210, and the structure of the connecting strip 100 tightly clamping the two plugs 210 on both sides of the hole 300 is formed;

[0043] Fifth, the worker cuts the connecting strip 100 exposed outside the second plug 210 on the indoor side, thus leaving a section of the connecting strip 100 inside the hole 300, the length direction of which is clamped with the rigid cylinders 220 of the two plugs 210 at both ends, and then the worker uses the rigid cylinder 220 on the indoor side as a filling port to inject filling material into the hole 300, and when the filling material overflows from the rigid cylinder 220 on the indoor side, it proves that the filling is dense, and the hole cover 230 is quickly covered on the rigid cylinder 220 on the indoor side to complete the plugging.

[0044] It should be noted that in the fifth step of the embodiment, the rigid cylinder 220 is used as a filling port, which is only a preferred way, and other ways can also be used to inject filling material into the hole 300, for example, an additional injection port is provided on the second plug 210, or the connecting strip 100 and the rigid cylinder 220 inside the second plug 210 are clamped together after the filling material is injected into the hole 300, which are some optional ways.

[0045] The above is only a specific implementation of the present application, and those skilled in the art can clearly understand that, for the convenience and brevity of description, the specific working process of the system, module and unit described above can refer to the corresponding process in the foregoing method embodiments, which will not be described here. It should be understood that the protection scope of the present application is not limited to this, and any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed in the present application, and these modifications or replacements should be covered within the protection scope of the present application.
