Description

Technical Field

[0001] The present application relates to the technical field of building sealing, and in particular to a casing sealing structure. Background Art

[0002] Currently, when pipes pass through walls during construction, they often require a casing to be placed inside the wall. Pipes can leak during use. Without a casing, leaking water or other media can seep directly into the wall, causing moisture, mold, and damage. A casing can prevent leaking media from diffusing into the wall, protecting its integrity.

[0003] When arranging the existing casing, it is first prefabricated on the steel frame inside the wall, and the casing is fixedly connected to the steel frame by welding. The welded steel frame will be placed in the construction area for standby or directly prepared into a prefabricated wall, but no pipes will be laid at this time. In order to ensure the cleanliness of the inside of the casing and prevent debris from entering the casing and damaging the waterproof coating on the inner wall of the casing, the end of the casing needs to be sealed when the pipeline is not laid. The traditional end sealing method generally uses oil paper for sealing.

[0004] The above-mentioned existing technical solutions have the following defects: the oil paper itself is brittle and the outdoor environment is unstable. For example, wind, sand, rain, etc. can easily damage the oil paper, resulting in the loss of the sealing purpose and poor protection effect. Utility Model Content

[0005] In order to achieve the purpose of improving the protection effect of the casing, the present application provides a casing sealing structure.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A sleeve sealing structure includes a first mounting assembly and a second mounting assembly, wherein the first mounting assembly is connected to the outer wall of the sleeve, and the second mounting assembly is used to seal the sleeve pipe mouth and is connected to the first mounting assembly; the second mounting assembly includes a sealing plate, a locking plate and a connecting ring, the sealing plate cover is provided to the pipe mouth of the sleeve to seal the sleeve, the locking plate is fixedly connected to the peripheral side of the sealing plate, an elastic member is provided between the connecting ring and the end of the locking plate facing away from the sealing plate, and the two ends of the elastic member are respectively fixedly connected to the connecting ring and the locking plate; the elastic member is used to drive the connecting ring to be inserted into the first mounting assembly, and the first mounting assembly limits the connecting ring.

[0008] By adopting the above solution, the first mounting assembly is first fixed to the outer wall of the sleeve, and then the sealing plate cover is arranged at the pipe mouth of the sleeve; and because an elastic member is provided, after the sealing plate cover is arranged at the pipe mouth of the sleeve, the elastic member pushes the connecting ring into the first mounting assembly under its own elastic action, and the first mounting assembly locks the connecting ring, so that the second mounting structure is fixedly connected to the first mounting assembly. Because the first mounting assembly is fixedly connected to the sleeve, the second mounting structure is fixedly connected to the sleeve, thereby achieving the purpose of sealing the sleeve and improving the protection effect of the sleeve.

[0009] Furthermore, the first mounting assembly includes a connecting plate, which is generally in the shape of a circular ring. The connecting plate is sleeved outside the sleeve and fixedly connected to the sleeve. A connecting groove is provided on the connecting plate corresponding to the connecting ring.

[0010] By adopting the above solution, when the elastic member drives the connecting ring to be inserted into the connecting groove, the positioning assembly limits the relative position relationship between the connecting ring and the connecting groove, and then the connecting ring limits the position relationship between the sealing plate and the sleeve through the elastic member.

[0011] Furthermore, a receiving groove is provided on the connecting plate, the receiving groove is located outside the connecting groove, and the positioning assembly is arranged in the receiving groove. The positioning assembly includes a pushing member and a locking member, one end of the pushing member is fixedly connected to the receiving groove, and the other end of the pushing member is fixedly connected to the locking member; a through hole is provided in the connecting groove corresponding to the locking member, and when the connecting ring is inserted into the connecting groove, the pushing member pushes the locking member through the through hole to the connecting groove to limit the connecting ring.

[0012] By adopting the above solution, when the connecting ring is inserted into the connecting groove, the pushing member can push the locking member through the through hole to the opposite side of the connecting groove. At this time, the locking member is located on the top wall of the connecting ring, thereby limiting the relative position relationship between the connecting ring and the connecting groove, and preventing the connecting ring from falling out in the direction away from the bottom wall of the connecting groove.

[0013] Furthermore, a blocking plate is provided on the side of the connecting groove close to the through hole, and the blocking plate is slidably connected to the side wall of the connecting groove.

[0014] Furthermore, a linkage plate is fixedly connected to the side of the blocking plate facing away from the through hole. When the connecting ring is inserted into the connecting groove, the connecting ring synchronously presses the connecting plate to move toward the bottom wall of the connecting groove.

[0015] By adopting the above scheme, when the elastic member drives the connecting ring to move toward the direction close to the bottom wall of the connecting groove, because a linkage plate is provided, the connecting ring abuts against the linkage plate, and the connecting ring presses the linkage plate to synchronously move toward the direction close to the bottom wall of the connecting groove, and the linkage plate drives the supporting member to shrink toward the direction close to the bottom wall of the connecting groove, thereby driving the blocking plate to slide along the side wall of the connecting groove, so that the through hole is opened; when the through hole is opened, the pushing member pushes the locking member through the through hole under its own elastic action and abuts against the side wall of the connecting groove away from the through hole, thereby locking the state of the connecting ring inserted into the connecting groove.

[0016] Furthermore, a placement groove is provided in the connection groove corresponding to the support member, one end of the support member is fixedly connected to the bottom wall of the placement groove, and the other end of the support member is fixedly connected to the blocking plate, and the placement groove is used to accommodate the support member.

[0017] By adopting the above solution and setting the placement groove, the support member can be completely received inside the placement groove, which facilitates the plug-in fit between the connecting ring and the connecting groove.

[0018] Furthermore, a locking groove is provided on a side of the connecting groove facing away from the through hole, corresponding to the locking piece, and the locking piece is plug-fitted into the locking groove.

[0019] By adopting the above solution, the locking piece is plugged into and matched with the locking groove, which can enhance the locking effect of the locking piece on the connecting ring.

[0020] Furthermore, a limiting assembly is provided between the pushing member and the locking member, and the limiting assembly includes a limiting plate and a sliding plate. The limiting plate is connected to the accommodating groove, a sliding groove is provided on the limiting plate, a slider is fixedly connected to the sliding plate, the slider is slidably connected to the sliding groove, and the limiting plate is connected to the locking member.

[0021] By adopting the above solution, when the pushing member drives the locking member to move, the slider moves synchronously along the sliding groove, thereby limiting the path of the pushing member and preventing the pushing member from deforming and causing the locking member to be unable to align with the through hole.

[0022] In summary, this application has the following technical effects:

[0023] 1. With this structure, the first mounting assembly is first fixed to the outer wall of the casing, and then the sealing plate cover is installed on the pipe opening of the casing. Because the elastic member is provided, after the sealing plate cover is installed on the pipe opening of the casing, the elastic member pushes the connecting ring into the first mounting assembly under its own elastic action. The first mounting assembly locks the connecting ring, so that the second mounting structure is fixedly connected to the first mounting assembly. Because the first mounting assembly is fixedly connected to the casing, the second mounting structure is also fixedly connected to the casing, thereby achieving the purpose of sealing the casing and improving the protective effect of the casing.

[0024] 2. By providing a positioning assembly, when the connecting ring is inserted into the connecting groove, the pushing member can push the locking member through the through hole to the opposite side of the connecting groove. At this time, the locking member is located on the top wall of the connecting ring, thereby limiting the relative position of the connecting ring and the connecting groove, preventing the connecting ring from falling away from the bottom wall of the connecting groove;
