Description

Technical Field

[0001] The utility model relates to the technical field of decoration, in particular to a wall hole embedded part. Background Art

[0002] During the installation of air conditioners and gas, pipes usually need to pass through the wall. If the existing hole drilling method is adopted, it is not only time-consuming and laborious, but also may cause the problem of exposed wall reinforcement. Therefore, during the construction of the wall, embedded parts are usually set at specific positions of the wall according to the possible subsequent installation needs, so as to avoid drilling holes in the wall later.

[0003] The traditional method for installing embedded parts is to drive long nails on the formwork, place the embedded pipe on the cantilever end of the long nail, and then seal the pipe orifice with tape.

[0004] In the traditional method of installing embedded parts, due to the impact of concrete during concrete pouring, the embedded pipe will shift, resulting in inaccurate positioning of the embedded pipe and affecting the subsequent use of the embedded part. At the same time, in the traditional method of using tape to seal the pipe orifice, it is very difficult to completely seal the pipe orifice. During the wall plastering stage, there is still a phenomenon that the paint enters the pipe and causes pipe pollution. Summary of the Utility Model

[0005] An object of the utility model is to solve the problems of inaccurate positioning of the embedded pipe and incomplete sealing of the pipe orifice.

[0006] In particular, an embodiment of the present application provides a wall hole embedded part, including:

[0007] An embedded pipe for passing through a hole in a casting formwork, and a first limiting structure is arranged on the inner wall of the embedded pipe;

[0008] Two positioning pipes, and a second limiting structure for cooperating with the first limiting structure is arranged on the outer wall of one end of the two positioning pipes, and an annular cover plate extending radially is formed on the outer wall of the other end. After the positioning pipes are connected to the embedded pipe, the annular cover plate presses the formwork for concrete pouring; and

[0009] A sealing cover, and the sealing cover is inserted into the positioning pipe to seal the pipe orifice of the positioning pipe.

[0010] Further, the sealing cover includes a base and a handle fixedly connected, and the handle is arranged on the side away from the positioning pipe and is arranged radially along the sealing cover, so as to operate the handle to assemble the sealing cover on the positioning pipe.

[0011] Further, a third limiting structure is arranged on the outer side wall of the base;

[0012] The inner wall of the positioning pipe is provided with a fourth limiting structure that cooperates with the third limiting structure. Through the cooperation of the third limiting structure and the fourth limiting structure, the plugging cover is fixed in the positioning pipe.

[0013] Further, the third limiting structure is an external thread provided on the base, and the fourth limiting structure is an internal thread provided on the inner wall of the positioning pipe.

[0014] Further, a concave cavity is formed on the side of the base away from the positioning pipe, and the handle is arranged in the concave cavity.

[0015] Further, the first limiting structure is an internal thread provided on the inner wall of the embedded pipe, and the second limiting structure is an external thread provided on the outer wall of the positioning pipe.

[0016] Further, a waterproof rubber pad is sleeved on the positioning pipe.

[0017] The beneficial effects of the present utility model are as follows:

[0018] 1. On the one hand, through the cooperation of the first limiting structure on the inner wall of the embedded pipe and the second limiting structure on the outer wall of the positioning pipe, the positioning pipe can clamp the formwork after being inserted into the embedded pipe, so that the embedded part is firmly installed on the formwork, avoiding the displacement of the embedded part during the concrete pouring; by installing a plugging cover on the positioning pipe, it is possible to avoid contaminating the pipeline during the subsequent decoration process.

[0019] 2. By providing a handle on the plugging cover, the operation is more convenient.

[0020] 3. A concave cavity is provided on the base, and the handle is arranged in the concave cavity, avoiding the handle protruding from the wall surface, which is convenient for later plastering the wall surface.

[0021] 4. By providing a third limiting structure on the outer wall of the base and a fourth limiting structure on the inner wall of the positioning pipe, the plugging cover is firmly installed in the positioning pipe.

[0022] 5. Threads are respectively provided on the inner wall of the embedded pipe and the outer wall of the positioning pipe. During the wall plastering stage, the depth of the positioning pipe inserted into the embedded pipe can be adjusted more precisely. When using the embedded part as a plastering guide, the thickness of the wall plastering can be controlled more precisely.

[0023] 6. A waterproof rubber ring is provided to improve the waterproof performance of the embedded part, and to prevent rainwater from seeping into the house through the gap between the annular cover plate and the wall, causing moisture and mildew on the inner wall.

Detailed implementation manners

[0029] To make the above - mentioned objects, features and advantages of the present application more obvious and understandable, the following will describe the detailed implementation manners of the present application with reference to the accompanying drawings. It can be understood that the specific embodiments described herein are only used to explain the present application, rather than limiting the present application. Additionally, it should be noted that for the sake of description, only the parts related to the present application are shown in the drawings, not all structures. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or devices.

[0031] Referring to "embodiment" in this context means that the specific features, structures or characteristics described in connection with the embodiment can be included in at least one embodiment of the present application. The phrase appears in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0032] As Figure 1As shown, in one embodiment, a wall hole embedded part 100 includes: an embedded pipe 1, two positioning pipes 3, and a plugging cover 4. The embedded pipe 1 is used to pass through a hole in a casting formwork 2, and a first limiting structure 11 is provided on the inner wall of the embedded pipe 1. On the outer walls of one ends of the two positioning pipes 3, there are second limiting structures 31 for cooperating with the first limiting structure 11, and annular covers 32 extending radially are formed on the outer walls of the other ends. After the positioning pipes 3 are connected to the embedded pipe 1, the annular covers 32 press against the formwork 2 for concrete casting. During the wall casting stage, first, a hole is drilled in the formwork 2, the wall hole embedded part 100 is inserted into the hole, and the annular cover 32 presses against the formwork 2 to prevent the pipe orifice from shifting under the impact of concrete during casting.

[0033] Furthermore, to prevent paint from entering the pipe and causing pipe pollution during the subsequent wall plastering stage, a plugging cover 4 is provided at the orifice of the positioning pipe 3 to plug the orifice. At the same time, by providing the plugging cover 4, when the embedded part 100 is not needed, it can prevent external rainwater from entering the room through the orifice.

[0034] As Figure 2 shown, in one embodiment, the plugging cover 4 includes a base 41 and a handle 42 fixedly connected. The handle 42 is arranged on the side away from the positioning pipe 3 and along the radial direction of the plugging cover 4.

[0035] As Figure 1 shown, to ensure that the plugging cover 4 can be firmly installed in the positioning pipe 3, a third limiting structure 43 is provided on the outer side of the base 41, and a fourth limiting structure (not shown) for cooperating with the third limiting structure 43 is provided on the inner wall of the positioning pipe 3. Through the cooperation of the third limiting structure 43 and the fourth limiting structure, the plugging cover 4 is firmly installed in the positioning pipe 3.

[0036] In one embodiment, the third limiting structure 43 is an external thread provided on the base 41, and the fourth limiting structure is an internal thread provided on the inner wall of the positioning pipe 3. The plugging cover 4 is threadedly connected to the positioning pipe 3. In another embodiment, the positioning pipe 3 and the plugging cover 4 can also be connected by a clamping method. Other connection methods that can firmly install the plugging cover 4 on the positioning pipe 3 all fall within the protection scope of the present utility model and will not be elaborated herein.

[0037] As Figure 1 shown, in one embodiment, a concave cavity 44 is formed on the side of the base 41 away from the positioning pipe 3, and the handle 42 is arranged in the concave cavity 44 so that the plugging cover 4 does not protrude from the wall surface, which not only meets the aesthetic requirements but also makes it more convenient for subsequent wall plastering.

[0038] As Figure 1As shown, in one embodiment, the first limiting structure 11 is an internal thread provided on the inner wall of the embedded pipe 1, and the second limiting structure 31 is an external thread provided on the outer wall of the positioning pipe 3. The embedded pipe 1 and the positioning pipe 3 are threadedly connected. During the plastering stage of the wall, according to the need for the thickness of the wall plastering, a certain length of the positioning pipe 3 can be taken out from the embedded pipe 1 as a plastering control block, providing a basis for controlling the thickness of the wall plastering. And by setting the thread, the extraction length of the positioning pipe 3 is more accurate, and the standard of the wall plastering thickness is also more accurate, ensuring the quality of the wall plastering.

[0039] When installing the wall embedded part 100 on the exterior wall, although the annular cover plate 32 can press tightly against the wall surface, due to the unevenness of the wall plastering, external rainwater may seep into the room through the gap between the annular cover plate 32 and the wall surface, resulting in the damp and mildew of the interior wall surface. As Figure 1 shown, in one embodiment, a waterproof rubber pad 5 is sleeved on the positioning pipe 3. While the annular cover plate 32 presses against the wall surface, the waterproof rubber pad 5 can fill the gap between the annular cover plate 32 and the wall surface to prevent rainwater from seeping in.

[0040] The above-described embodiments merely represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
