Description

Technical Field

[0001] This utility model belongs to the field of sleeve bending connection technology, specifically a novel bending connection through-wall sleeve. Background Technology

[0002] Wall bushings are also called wall pipes, waterproof sleeves, or wall embedded pipes. Waterproof sleeves are divided into rigid waterproof sleeves and flexible waterproof sleeves. In the power industry, those used for conducting electricity are called AC wall bushings. Based on the material, they can be divided into dry capacitor type AC wall bushings and porcelain insulated AC wall bushings, which are abbreviated as silicone rubber bushings and burglar bushings, respectively.

[0003] Existing through-wall sleeves with bend connections mostly adopt a simple bend pipe structure. By setting an installation point at the bend of the pipe, the bent pipe is fitted inside the sleeve. However, in the production process of bend-connected through-wall sleeves, the size of the sleeve needs to be enlarged accordingly to facilitate the installation of the pipe. As a result, the bend of the pipe cannot make full contact with the pipe, lacking a stable support point, which can easily lead to damage to the pipe inside the sleeve.

[0004] Therefore, this utility model provides a novel through-wall sleeve with a bending connection. Utility Model Content

[0009] Preferably, the multiple rubber clamping blocks have internal deformation cavities, and the deformation cavities are set according to the size of the rubber clamping blocks; this step achieves controllable clamping at the corner of the pipe inside the sleeve by opening deformation cavities inside the rubber clamping blocks, which improves the stability and flexibility of the sleeve and enhances the reliability of the sleeve clamping function.

[0010] Preferably, the built-in ribs and built-in rings are made of stainless steel; the first pair of connecting pipes, the second pair of connecting pipes, and the limiting block are also made of stainless steel. This step improves the stability of the new type of bent-connected through-wall sleeve by using stainless steel, which helps to prevent the built-in ribs and built-in rings from rusting inside the first and second sleeves, reduces the deformation between the first pair of connecting pipes, the second pair of connecting pipes, and the limiting block, and thus reduces the shaking of the sleeve.

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 4As shown, a novel through-wall sleeve with a bent connection according to an embodiment of the present invention includes a first sleeve 1 and a second sleeve 3. A reinforcing ring 2 is fixedly connected to the sidewalls of the first sleeve 1 and the second sleeve 3. A first pair of connecting pipes 4 is fixedly connected to the end of the first sleeve 1, and a second pair of connecting pipes 5 is fixedly connected to the end of the second sleeve 3. A positioning plate 8 is provided at the end of the first sleeve 1 near the end of the second sleeve 3. A fixing strip 13 is fixedly connected inside the positioning plate 8. A rubber clamping block 11 is fixedly connected inside the fixing strip 13, and multiple rubber clamping blocks 11 are arranged in a circumferential array. Clamping grooves 14 are formed on the sidewalls of the rubber clamping blocks 11, and the clamping grooves 14 are symmetrically arranged. The first pair of connecting pipes 4 and... The second connecting pipe 5 has an internal extrusion bevel 20, which is positioned to correspond to the size and location of the rubber clamping block 11. Fixing protrusions 7 are fixed to the side walls of the first sleeve 1 and the second sleeve 3, arranged in a circumferential array. During operation, workers can connect the multiple fixing protrusions 7 on the side walls of the first sleeve 1 and the second sleeve 3 using bolts, thereby connecting the first sleeve 1 and the second sleeve 3 together. Simultaneously, the corners of the internal pipes of the first sleeve 1 and the second sleeve 3 are clamped and fixed. During this process, workers install the first sleeve 1 inside the wall and complete the connection between the pipe and the second sleeve 3. After the second sleeve 3 is installed, multiple bolts can be installed on the multiple fixing protrusions 7 on the side walls of the first pair of pipes 4 and the second pair of pipes 5, and the bolts are tightened. During the tightening process, the first pair of pipes 4 and the second pair of pipes 5 will move closer to each other, and the extrusion slopes 20 at the ends of the first pair of pipes 4 and the second pair of pipes 5 will come into contact with multiple rubber clamping blocks 11 and apply pressure to the rubber clamping blocks 11. The multiple rubber clamping blocks 11 will then deform under force and come into contact with the pipes inside the first sleeve 1 and the second sleeve 3. After the two come into contact, the bolts between the multiple fixing protrusions 7 will continue to be tightened, and the multiple rubber clamping blocks 11 will continue to deform until the rubber clamps... The clamping groove 14 on the side wall of the holding block 11 is in close contact with the pipe, and the end of the second pair of pipes 5 contacts the side wall of the positioning plate 8, thus completing the installation. The fixing strip 13 fixes multiple rubber clamping blocks 11 inside the positioning plate 8, and the reinforcing ring 2 strengthens the structural strength of the first sleeve 1 and the second sleeve 3. This step, by setting the fixing protrusion 7 and the rubber clamping block 11, and opening the clamping groove 14 on the side wall of the rubber clamping block 11, clamps and fixes the corner of the pipe inside the sleeve, which helps to reduce shaking, solves the problem of lack of support at the bend of the pipe inside the sleeve, and improves the stability and protection capability of the new type of bent-connection through-wall sleeve.

[0026] like Figure 5As shown, the first sleeve 1 and the second sleeve 3 are internally provided with built-in rings 18, and multiple built-in rings 18 are arranged in a circular array; built-in ribs 17 are fixedly connected between the multiple built-in rings 18, and multiple built-in ribs 17 are arranged in a linear array; the ends of the built-in ribs 17 are fixedly connected to the inside of the first pair of connecting pipes 4 and the second pair of connecting pipes 5; during operation, the built-in ribs 17 and the built-in rings 18 located inside the first sleeve 1 and the second sleeve 3 can provide support to the first sleeve 1 and the second sleeve 3 through their own elasticity, and the inside of the first pair of connecting pipes 4 and the second pair of connecting pipes 5... The built-in ribs 17 and built-in rings 18 can provide support to the first pair of pipes 4 and the second pair of pipes 5 through their own elasticity. The multiple evenly arranged built-in ribs 17 and built-in rings 18 can average the stress on the sleeve. This step strengthens the structural strength of the first sleeve 1, the second sleeve 3, the first pair of pipes 4 and the second pair of pipes 5 by setting the built-in ribs 17 and built-in rings 18, which helps to solve the problem of uneven stress on the sleeve, improves the protection capability of the new type of bent-connected through-wall sleeve, expands the application scenarios of the sleeve, and extends the service life of the sleeve.

[0027] like Figures 2 to 4 As shown, limiting blocks 9 are fixed to the sidewalls of the first pair of connecting pipes 4, and multiple limiting blocks 9 are arranged in a circumferential array; limiting grooves 10 are formed on the sidewalls of the positioning disk 8, and multiple limiting grooves 10 are set to correspond to the size and position of the limiting blocks 9; the end of the second pair of connecting pipes 5 is provided with an installation groove 19, and the installation groove 19 is set to correspond to the size of the limiting blocks 9; during operation, after the operator connects the first sleeve 1 and the second sleeve 3 together with bolts, multiple limiting blocks 9 located at the end of the first pair of connecting pipes 4 will pass through the sidewalls of the positioning disk 8, thereby restricting the movement of the positioning disk 8. This is accompanied by the first pair of connecting pipes 4, the positioning disk 8, and the second pair of connecting pipes 5. When the connecting pipe 5 is clamped, the position of the positioning plate 8 will be firmly locked. At the same time, multiple limiting blocks 9 will pass through the limiting groove 10 and enter the installation groove 19 corresponding to the second pair of connecting pipes 5. In daily use, the multiple limiting blocks 9 entering the installation groove 19 can work with the fixing protrusion 7 and bolts to provide additional support for the second sleeve 3. This step, by setting the limiting blocks 9 and the installation groove 19 to provide additional support for the second sleeve 3, helps to prevent the second sleeve 3 from bending under force, enhances the structural strength of the new type of bent-connected through-wall sleeve, improves the protective capability of the new type of bent-connected through-wall sleeve, and extends its service life.

[0028] like Figure 4As shown, multiple rubber clamping blocks 11 have deformable cavities 12 inside, and the deformable cavities 12 are set according to the size of the rubber clamping blocks 11. During operation, the operator can control the degree of deformation of the rubber clamping blocks 11 by controlling the size of the deformable cavities 12 inside the rubber clamping blocks 11, thereby controlling the clamping effect of the rubber clamping blocks 11 on the pipe inside the sleeve. This step, by opening deformable cavities 12 inside the rubber clamping blocks 11, makes the clamping at the corner of the pipe inside the sleeve controllable, improves the stability and flexibility of the sleeve, and enhances the reliability of the sleeve clamping function.

[0029] like Figure 2 and Figure 5 As shown, the built-in rib 17 and built-in ring 18 are made of stainless steel; the first pair of connecting pipes 4, the second pair of connecting pipes 5, and the limiting block 9 are also made of stainless steel. During operation, the stainless steel built-in rib 17 and built-in ring 18 can effectively prevent rusting, thus preventing the built-in rib 17 and built-in ring 18 from rusting and separating. The stainless steel first pair of connecting pipes 4, the second pair of connecting pipes 5, and the limiting block 9 can improve the stability of the connection by utilizing the rigidity of stainless steel. This step improves the stability of the through-wall sleeve of the new type of bent connection by using stainless steel, which helps to prevent the built-in rib 17 and built-in ring 18 from rusting inside the first sleeve 1 and the second sleeve 3, reduces the deformation between the first pair of connecting pipes 4, the second pair of connecting pipes 5, and the limiting block 9, and thus reduces the shaking of the sleeve.

[0030] like Figures 1 to 3 As shown, a support sleeve 6 is fixedly connected to the side wall of the second connecting pipe 5, and a fixing block 16 is fixedly connected to both ends of the support sleeve 6. During operation, the support sleeve 6 and the fixing block 16 can provide support for the internal pipe of the second sleeve 3 through their larger size, thereby maintaining the stability of the internal pipe. This step improves the safety of the sleeve by setting the support sleeve 6 and the fixing block 16 to protect the internal pipe of the sleeve, which helps to avoid deformation at the bend of the internal pipe of the sleeve.

[0031] like Figure 3 As shown, a reinforcing rod 15 is fixed between two fixed blocks 16, and multiple reinforcing rods 15 are arranged in a circumferential array. During operation, the multiple reinforcing rods 15 arranged in a circumferential array strengthen the structural stability of the support sleeve 6 by connecting the two fixed blocks 16. This step maintains the stability of the support sleeve 6 by setting the reinforcing rods 15, which helps to prevent the support sleeve 6 from deforming, improves the structural stability of the sleeve, and helps to extend its service life.

[0032] During operation, workers can connect the first sleeve 1 and the second sleeve 3 together by using bolts to connect multiple fixing protrusions 7 on the side walls. Simultaneously, the corners of the internal pipes of the first sleeve 1 and the second sleeve 3 are clamped and fixed. After installing the first sleeve 1 inside the wall and completing the installation of the pipes and the second sleeve 3, workers can install multiple bolts on the fixing protrusions 7 on the side walls of the first connecting pipe 4 and the second connecting pipe 5, and tighten the bolts. During the tightening process, the first connecting pipe 4 and the second connecting pipe 5 will move closer to each other, and the extrusion slopes 20 at the ends of the first connecting pipe 4 and the second connecting pipe 5 will contact multiple rubber clamping blocks 11, thus clamping the rubber... When pressure is applied to the holding block 11, the multiple rubber clamping blocks 11 deform under stress and come into contact with the pipes inside the first sleeve 1 and the second sleeve 3. After contact, the bolts between the multiple fixing protrusions 7 will continue to tighten, and the multiple rubber clamping blocks 11 will continue to deform until the clamping grooves 14 on the side wall of the rubber clamping block 11 are in close contact with the pipe, and the end of the second connecting pipe 5 contacts the side wall of the positioning plate 8, thus completing the installation. The fixing strip 13 fixes the multiple rubber clamping blocks 11 inside the positioning plate 8, and the reinforcing ring 2 strengthens the structural strength of the first sleeve 1 and the second sleeve 3. The built-in ribs 17 and the built-in rings 18 located inside the first sleeve 1 and the second sleeve 3 can use their own elasticity to hold the first sleeve 1 and the second sleeve 3 together. With the support applied, the built-in ribs 17 and built-in rings 18 inside the first pair of connecting pipes 4 and the second pair of connecting pipes 5 can provide support through their own elasticity. Multiple evenly arranged built-in ribs 17 and built-in rings 18 can evenly distribute the stress on the sleeve. After the worker connects the first sleeve 1 and the second sleeve 3 together with bolts, multiple limiting blocks 9 located at the end of the first pair of connecting pipes 4 will pass through the side wall of the positioning plate 8, thereby restricting the movement of the positioning plate 8. With the clamping of the first pair of connecting pipes 4, the positioning plate 8, and the second pair of connecting pipes 5, the position of the positioning plate 8 will be securely locked. Simultaneously, the multiple limiting blocks 9, after passing through the limiting groove 10, will enter the corresponding installation groove 19 of the second pair of connecting pipes 5. In daily use, multiple... The limiting block 9 inside the mounting groove 19 can cooperate with the fixing protrusion 7 and bolts to provide additional support for the second sleeve 3. Workers can control the deformation degree of the rubber clamping block 11 by controlling the size of the deformation cavity 12 inside the rubber clamping block 11, thereby controlling the clamping effect of the rubber clamping block 11 on the internal pipe of the sleeve. The stainless steel internal ribs 17 and internal rings 18 effectively prevent rusting, thus preventing the internal ribs 17 and internal rings 18 from rusting and separating. The stainless steel first pair of connecting pipes 4, second pair of connecting pipes 5, and limiting block 9 can improve the stability of the connection by utilizing the rigidity of stainless steel. The support sleeve 6 and fixing block 16 can provide support for the internal pipe of the second sleeve 3 through their larger size, thereby maintaining the stability of the internal pipe.Multiple reinforcing rods 15 arranged in a circular array enhance the structural stability of the support sleeve 6 by connecting two fixing blocks 16.
