Description

Technical Field

[0001] This utility model relates to the field of exterior wall construction technology, and more specifically, to a temporary sealing device for reserved openings in exterior walls. Background Technology

[0002] During basement construction, to avoid water seepage caused by openings in the exterior walls for outdoor pipeline installation, construction companies typically leave openings during concrete pouring. However, due to the relatively long construction period, water often seeps into the basement through these openings due to groundwater or rain / snow, potentially causing corrosion and damage to indoor facilities before pipeline installation is complete. Furthermore, traditional opening sealing procedures are cumbersome, use expensive materials, and require a dry, water-free environment. When water is present at the opening, construction workers often need to expend significant manpower and resources to clean and dry the opening before sealing it.

[0003] Therefore, there is an urgent need for a temporary sealing device for pre-reserved openings in exterior walls that can quickly achieve water shut-off and cleaning before construction to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a temporary sealing device for reserved openings in exterior walls. The temporary sealing device for reserved openings in exterior walls provided by this utility model has the advantages of rapid water shut-off sealing, solving the problems of complex construction, incomplete water shut-off and cleaning, and poor sealing effect of traditional opening sealing methods.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

The first self-locking nut and the second self-locking nut are respectively disposed on both sides of the first elastic sealing member and abut against the first elastic sealing member to restrict the movement of the first elastic sealing member.

[0010] Preferably, the diameter of the first elastic sealing element is larger than the diameter of the reserved opening.

[0011] Preferably, the second sealing component includes a movable element and a second elastic sealing element;

[0012] The movable component is movably mounted on the connecting screw so that it can move as the connecting screw rotates. One end of the second elastic sealing component is fixedly connected to the movable component, and the other end of the second elastic sealing component is fixedly connected to the limiting component. The second elastic sealing components are symmetrically arranged on both sides of the connecting screw, and the diameter of the second elastic sealing component can increase or decrease as the movable component moves.

[0025] Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0028] like Figure 1 As shown, a temporary sealing device for a reserved opening in an exterior wall includes: a first sealing component, a second sealing component, a connecting screw 11, a limiting component, and a driving component 1. The first sealing component, the second sealing component, and the limiting component are all coaxially mounted on the connecting screw 11. The output shaft of the driving component 1 is connected to the connecting screw 11. The limiting component is fixedly connected to the connecting screw 11 and is located near one end of the driving component 1. One end of the second sealing component is connected to the limiting component, which can be engaged with the outside of the reserved opening. The other end of the second sealing component is rotatably connected to the connecting screw 11. The first sealing component is fixedly connected to the connecting screw 11, and the outer wall of the first sealing component can abut against the inner wall of the reserved opening.

[0029] In this embodiment, the temporary sealing device for the reserved opening in the exterior wall is configured with a first sealing component. When the device is driven into the reserved opening by the driving component 1, the first sealing component abuts against the inner wall of the reserved opening. Under the action of the driving component 1, the first sealing component is interference-fitted with the inner wall of the reserved opening and continuously moves into the opening. Through the movement of the first sealing component, the temporary sealing device for the reserved opening in the exterior wall can gradually push the debris in the reserved opening to the outside of the opening and form the first blockage of the water flow in the opening, preventing external water from flowing into the opening. Furthermore, during the process of the temporary sealing device for the reserved opening in the exterior wall being inserted into the opening, the setting of the limiting component allows the entire device to be locked onto one end of the reserved opening. After the limiting component is locked, the driving component 1 continues to act on the connecting screw 11. At this time, the first sealing component stops penetrating the opening, and the diameter of the second sealing component gradually increases as the connecting screw 11 continues to rotate clockwise, further forming a second seal on the opening, preventing water from seeping in through the gaps of the first sealing component. In addition, the second sealing component can monitor the pressure between the opening and the second sealing component in real time to determine the sealing performance between the second sealing component and the opening.

[0030] This temporary sealing device for pre-reserved openings in exterior walls, through the arrangement of a first sealing component and a second sealing component, not only effectively cleans residual debris from the opening but also seals it with the double sealing components, preventing water seepage during subsequent processes. This allows for rapid sealing of the opening even in the presence of flowing water. Furthermore, after construction is completed, the device can be reusable by using a reverse-acting connecting screw 11 to reduce the diameter of the second sealing component, causing the first sealing component to detach from the opening. This improves economic efficiency, simplifies the sealing process, reduces labor intensity, and saves manpower and resources.

[0031] like Figure 1 As shown, the first sealing assembly includes a first self-locking nut 10, a second self-locking nut 8, and a first elastic sealing member 9. Both the first self-locking nut 10 and the second self-locking nut 8 are connected to the connecting screw 11. The first elastic sealing member 9 is symmetrically arranged on the connecting screw 11 about its axis. The first self-locking nut 10 and the second self-locking nut 8 are respectively located on both sides of the first elastic sealing member 9 and abut against it to restrict its movement. The diameter of the first elastic sealing member 9 is larger than the diameter of the reserved opening.

[0032] In this embodiment, the first self-locking nut 10 and the second self-locking nut 8 ensure that the first elastic sealing member 9, which is mounted on the connecting screw 11 in the temporary sealing device for the reserved opening in the external wall, does not change position when the connecting screw 11 rotates. When the device is pushed into the opening, the position of the first elastic sealing member 9 pushes out any debris from the opening and achieves the first sealing of the opening. Furthermore, in a preferred embodiment, since the waterproof sleeves used for the reserved opening all have corresponding specifications, the diameter of the first elastic sealing member 9 is 5mm larger than the inner diameter of the waterproof sleeve used for the reserved opening. This allows the first elastic sealing member 9 to fit tightly against the inner wall of the opening, thereby achieving the purpose of pushing out and sealing the impurities in the opening.

[0033] See Figure 1 The second sealing assembly includes a movable component and a second elastic sealing component 5. The movable component is movably mounted on the connecting screw 11 so that it can move with the rotation of the connecting screw 11. One end of the second elastic sealing component 5 is fixedly connected to the movable component, and the other end is fixedly connected to a limiting component. The second elastic sealing components 5 are symmetrically arranged on both sides of the connecting screw 11 and can move with the movable component. The movable component includes a flange nut 6 and a movable component 7. The movable component 7 is fixedly mounted on the flange nut 6 and symmetrically arranged about the flange nut 6 as an axis. The movable component 7 is fixedly connected to the second elastic sealing component 5, and the flange nut 6 is threadedly connected to the connecting screw 11.

[0034] In this embodiment, the movable part is preferably a thick iron sheet with a diameter smaller than the inner diameter of the reserved opening. Under the action of the connecting screw 11, the flange nut 6, which is threadedly connected to the connecting screw 11, moves along the connecting screw 11 as the connecting screw 11 rotates. When the connecting screw 11 rotates clockwise, the flange nut 6 moves along the connecting screw 11 toward the limiting piece 4. The movement of the flange nut 6 causes the movable part to approach the limiting component and compress the second elastic sealing member 5, which is disposed between the limiting component and the movable part. This causes the length of the second elastic sealing member 5 to decrease and the diameter to increase until the second elastic sealing member 5 abuts against the inner wall of the opening. At this time, the second elastic sealing member 5 forms a second seal, further preventing water and other substances that seep in through the first elastic sealing member 9 from entering the room.

[0035] In a preferred embodiment, the diameter of the movable member 7 is smaller than the inner diameter of the reserved opening. The diameter of the second elastic sealing member 5 gradually decreases from the middle to both ends along the length of the connecting screw 11, and a pressure sensor is provided at the point of maximum diameter in the middle of the second elastic sealing member 5. In this embodiment, the pressure sensor is located at the point where the second elastic sealing member 5 is most easily deformed by compression, and the pressure generated by the compression between the second elastic sealing member 5 and the inner wall of the opening can be monitored in real time. The pressure sensor is preferably a pressure film sensor.

[0036] In one embodiment, the limiting assembly includes a limiting plate 4 and a third self-locking nut 2. The limiting plate 4 is fixedly connected to the second sealing assembly and is snapped into the pre-drilled opening. The third self-locking nut 2 is connected to a connecting screw 11, and the limiting plate 4 passes through the connecting screw 11. The third self-locking nut 2 abuts against the limiting plate 4 to restrict its movement. The limiting assembly also includes a washer 3, which is disposed between the third self-locking nut 2 and the limiting plate 4.

[0037] In this embodiment, the limiting piece 4 allows the drive component 1 to be abutted against the outside of the opening during the pushing process, while the third self-locking nut 2 prevents the limiting piece 4 from axially shifting as the connecting screw 11 rotates. Furthermore, the washer 3 positioned between the third self-locking nut 2 and the limiting piece 4 further prevents friction between them, extending their service life and reducing wear.

[0038] In a preferred embodiment, the first elastic sealing member 9 and the second elastic sealing member 5 are both preferably rubber balls, the limiting piece 4 and the moving member 7 are both preferably iron pieces, and the driving member 1 can be a drive motor, a handle, etc.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
