It is suitable for repairing drainage holes and gaps in water pipes in construction projects. It can quickly and effectively fill these defects and is a commonly used hole repair device in construction projects.

[0003] Existing hole-sealing devices, when repairing holes, mainly use two semi-circular ring structures to connect to the outside of the pipe and then seal the hole. Since the diameter of the holes varies, the hole-sealing devices are mostly connected to the wall by adhesive. The forming time is long, and during the shaping process, the device may shift or detach in part, thereby reducing its fixing effect and causing it to fall off later in use. Utility Model Content

[0004] The purpose of this utility model is to provide a hole-filling device for building engineering, so as to solve the problem mentioned in the background art that the device is mostly connected to the wall by adhesive, which has a long molding time and may cause positional displacement or partial detachment during the molding process, thereby reducing its fixing effect.

[0008] Preferably, one end of the positioning ring is internally rotatably connected to a threaded rod, and the threaded rod is externally threaded to a butterfly nut; the other end of the positioning ring is provided with a snap-fit ​​groove.

[0009] Preferably, the threaded rods of one set of sealing components are rotatably engaged with the locking groove of another set of sealing components, and the butterfly nuts of one set of sealing components abut against the outer wall of the positioning ring of the other set of sealing components.

[0021] 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.

[0022] Please see Figure 1-5 One embodiment of this utility model is a hole-filling device for building construction, comprising:

[0023] Two sets of sealing components 1, each of which includes a sealing ring 11 and a positioning ring 12, and the sealing rings 11 of the two sets of sealing components 1 are connected in a ring structure;

[0024] The positioning component 2 includes a worm gear 21, with a worm wheel 22 meshing externally. A main shaft 23 is fixedly connected to the center of the worm wheel 22, and an abutment rod 25 is fixedly connected externally to the main shaft 23. An anti-slip ball 26 is fixedly connected to the end of the abutment rod 25. A through hole is provided on the sealing ring 11 corresponding to the worm gear 21, and the end of the worm gear 21 is flush with the surface of the sealing ring 11. Through this structure, the rotation of the worm gear 21 drives the worm wheel 22 and the main shaft 23 to rotate. Furthermore, the rotation of the abutment rod 25 causes the anti-slip ball 26 to abut against the inner wall of the opening, thereby achieving the locking and squeezing positioning of the sealing component 1. This effectively improves the stability of the device installation and prevents it from sliding off later in use.

[0025] Furthermore, a threaded rod 13 is rotatably connected to one end of the positioning ring 12, and a butterfly nut 14 is threadedly connected to the outside of the threaded rod 13. A snap-fit ​​groove 17 is provided at the other end of the positioning ring 12. The threaded rod 13 of one set of sealing components 1 is rotated and snapped into the snap-fit ​​groove 17 of another set of sealing components 1. The butterfly nut 14 of one set of sealing components 1 abuts against the outer wall of the positioning ring 12 of another set of sealing components 1. Through the docking of the two sets of sealing components 1, the threaded rod 13 and the butterfly nut 14 are used to achieve mutual snap-fit ​​and positioning, so that the two sealing rings 11 can be spliced ​​into a firm ring and fitted onto the outer wall of the pipe.

[0026] Furthermore, the two ends of the positioning rings 12 that are close to each other are respectively provided with plug-in posts 15 and positioning holes 16, and the plug-in posts 15 and positioning holes 16 of the two sets of sealing components 1 are plugged into each other and engaged. The plugging of the plug-in posts 15 and positioning holes 16 achieves the pre-tightening connection between the two, thereby preventing positional displacement when they are locked together and improving the convenience of subsequent operations.

[0027] Furthermore, the positioning components 2 are provided in four sets, with each pair of positioning components 2 connected to the outer wall of a sealing component 1. The outer wall of the worm gear 21 is rotatably connected to the outer wall of the positioning ring 12 through the bearing seat 24, and the outer wall of the main shaft 23 is rotatably connected to the outer wall of the sealing ring 11 through the bearing seat 24, while ensuring the stability of its support.

[0028] Furthermore, the worm gear 21 has an internal hexagonal groove at the center of one end inside the sealing ring 11, the abutment rod 25 has a Y-shaped structure, and the outer wall of the anti-slip ball 26 is provided with anti-slip texture. The internal hexagonal groove of the worm gear 21 facilitates its rotation drive and avoids causing protrusions on the outside of the sealing ring 11, ensuring aesthetics. The anti-slip texture on the outer wall of the anti-slip ball 26 can improve the friction between the anti-slip ball 26 and the inner wall of the opening, thereby improving its positioning stability. Moreover, the adjustment angle of each group of positioning components 2 can effectively adapt to the inner wall of the opening for abutment positioning.

[0029] Working principle: The threaded rods 13 used in this application are all products that can be purchased directly from the market. Their principles and connection methods are existing technologies known to those skilled in the art, so they will not be described in detail here. When using this utility model, the two sets of sealing components 1 are first docked and engaged, so that the plug-in post 15 and the positioning hole 16 are inserted into each other. Then, the threaded rod 13 and the butterfly nut 14 are engaged and squeezed to complete the tight fixing of the sealing ring 11. Then, the positioning ring 12 is placed inside the opening. By rotating the worm gear 21, the abutment rod 25 is tilted, and the anti-slip ball 26 is positioned against the inner wall of the opening to complete the squeezing and engaging installation of the sealing component 1, ensuring the overall stability of the device installation.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
