Description

Technical Field

[0001] This utility model belongs to the field of wall sleeve technology, and in particular relates to a sealing structure for a wall sleeve. Background Technology

[0002] Through-wall sleeves are key components used in fields such as power and construction for conducting electricity or allowing pipes to pass through walls. They are mainly divided into two categories: rigid waterproof sleeves and flexible waterproof sleeves. Rigid waterproof sleeves are suitable for static waterproofing scenarios such as basements. They are made of steel pipes with wing rings and are mainly used for general pipes passing through walls.

[0003] A search revealed an existing technology (publication number: CN223167995U) for a wall sleeve, which states that it "includes a connecting sleeve and porcelain sleeves installed at both ends of the connecting sleeve. The connecting sleeve includes a connecting seat and a connecting flange. One end of the connecting seat is provided with a connecting flange, and the connecting flange is fitted onto the surface of one of the porcelain sleeves. The connecting seat is located between the connection points of the two porcelain sleeves." However, this existing technology lacks a sealing structure. Vibrations generated during fluid flow in the pipeline can cause the pipeline to collide with the wall sleeve, easily causing damage. Furthermore, pipeline vibration can also lead to loosening of the wall sleeve. Therefore, designing a sealing structure for the wall sleeve is essential. Utility Model Content

[0004] This utility model provides a sealing structure for a through-wall sleeve, which aims to solve the problem that the lack of a sealing structure in the prior art leads to vibrations generated when fluid flows in the pipe, causing the pipe to collide with the through-wall sleeve and easily resulting in damage.

[0005] This utility model is implemented as follows: a through-wall sleeve sealing structure includes: a sleeve body; two inflatable frames assembled inside the sleeve body, the two inflatable frames being symmetrically arranged, each inflatable frame having a folded airbag inside, and a plurality of inflatable heads equidistantly arranged on the inner side of each inflatable frame, the other end of each inflatable head being inserted and connected to the air inlet of the folded airbag, a rubber pad being glued to the inner side of the folded airbag, and a pair of sponge strips being glued to the outer wall of the rubber pad, a connecting pipe being provided between the two inflatable frames, and both ends of the connecting pipe being inserted and connected to the two inflatable frames respectively, a material conveying pipe being welded to one of the inflatable frames, and an air inlet being provided on the inflatable frame, with an air inlet pipe inserted into the air inlet.

[0006] Preferably, the air intake pipe is a flexible hose made of PVC material, and a sealing plug is inserted into the end of the air intake pipe away from the air inlet.

[0007] Preferably, a limiting ring is welded to the outer wall of the sleeve body, and a plurality of fixing holes are equally spaced on the limiting ring, and bolts are installed in the fixing holes by means of threads.

[0008] Preferably, a plurality of protective covers are welded at equal intervals on the limiting ring, the number of protective covers being the same as the number of fixing holes, and the positions of the fixing holes and the protective covers corresponding one-to-one.

[0009] Preferably, a cover plate is hinged to the protective cover, and the size of the cover plate is the same as the size of the protective cover.

[0010] Preferably, both ends of the conveying pipe pass through the inflatable frame.

[0011] Preferably, a sealing plate is screwed onto each of the two inflatable frames, and the center of the sealing plate is hollowed out.

[0012] Preferably, the rubber pad is made of neoprene rubber and the sponge strip is made of EVA foam.

[0013] Compared with related technologies, the through-wall sleeve sealing structure provided by this utility model has the following beneficial effects: 1. By inserting the pipe into the casing body and blowing air into the inflation frame through the air inlet pipe, the air enters the folding airbag through the inflation head and inflates the folding airbag. The folding airbag inflates and squeezes the pipe inserted into the casing body, thus sealing and fixing the pipe. Rubber pads and sponge strips can improve the tightness of the fit between the folding airbag and the pipe and increase friction. Foaming agent is filled into the casing body through the feed pipe to fill the space inside the casing body, thereby improving the sealing effect. The connecting pipe can connect the two inflation frames to facilitate the inflation of the folding airbag. This method can increase the sealing between the pipe and the casing body, thereby avoiding vibrations caused by fluid flow in the pipe, which could cause the pipe and the casing body to collide and cause damage. At the same time, it can effectively prevent the casing body from loosening.

[0014] 2. Bolts can be used to connect the limiting ring to the installation position to fix the main body of the sleeve. The cover plate can be used to seal the bolts in the protective cover to prevent external moisture from entering the fixing hole and causing rusting. This can ensure the tightness of the bolt connection. The sealing plate can limit the foaming position of the foaming agent. Attached Figure Description

[0021] In a further preferred embodiment of the present invention, the air inlet pipe 10 is a flexible hose made of PVC material, and a sealing plug 11 is inserted into the end of the air inlet pipe 10 away from the air inlet 9.

[0022] In this embodiment, the air intake pipe 10 can be sealed using the sealing plug 11. Example 2

[0023] Based on Embodiment 1, a preferred embodiment of the through-wall sleeve sealing structure provided by this utility model is as follows: Figures 1 to 4 As shown: a limiting ring 12 is welded to the outer wall of the sleeve body 1, and several fixing holes 13 are equally spaced on the limiting ring 12. Bolts 14 are installed on the fixing holes 13 by thread.

[0024] In this embodiment, the limiting ring 12 can be connected to the installation position by bolt 14 to achieve the effect of fixing the sleeve body 1.

[0025] In a further preferred embodiment of this utility model, a plurality of protective covers 15 are welded at equal intervals on the limiting ring 12. The number of protective covers 15 is the same as the number of fixing holes 13, and the positions of the fixing holes 13 and the protective covers 15 correspond one-to-one.

[0035] In summary, by inserting the pipe into the sleeve body 1 and blowing air into the inflation frame 2 through the air inlet pipe 10 from the inflation port 9, the gas can enter the folded airbag 3 through the inflation head 4 and inflate the folded airbag 3. The folded airbag 3 inflates and compresses the pipe inserted into the sleeve body 1, thus sealing and fixing the pipe. The rubber pad 5 and sponge strip 6 can improve the tightness of the fit between the folded airbag 3 and the pipe and increase friction. Foaming agent is filled into the sleeve body 1 through the feed pipe 8, which can improve the internal space of the sleeve body 1. The filling process improves the sealing effect. The sealing plate 17 can limit the foaming position of the foaming agent. The connecting pipe 7 can connect the two inflation frames 2 to each other, making it convenient to inflate the folded airbag 3. The bolt 14 can connect the limiting ring 12 to the installation position to achieve the fixing effect of the sleeve body 1. The cover plate 16 can seal the bolt 14 in the protective cover 15 to prevent external moisture from entering the fixing hole 13 and causing rust at the fixing hole 13, thus ensuring the tightness of the bolt 14 connection.
