They can protect electrical circuits, ensure electrical safety, facilitate wiring and maintenance, and provide waterproofing, dustproofing, and moisture protection. Under certain conditions, multiple conduits need to be spliced ​​together to meet more building needs. Therefore, an external device is needed to lock the conduit joints together to prevent them from loosening and separating.

[0003] Building electrical conduits typically consist of sealing rings at pipe joints and locking devices at pipe joints. Currently, pipe joints on the market are usually fixed together by welding or other methods, which is cumbersome and makes disassembly difficult, resulting in difficulties in pipe inspection and maintenance. The sealing rings currently on the market have poor sealing performance and cannot meet the needs of more buildings.

[0004] In response to the technical problems of poor sealing performance due to difficulty in installing and replacing sealing devices and sealing rings, this application proposes a sealing device for pipes used in building electrical systems. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A sealing device for building electrical pipes includes two pipe bodies aligned with each other at opposite ends. A first clamping strip is installed on the upper side of the middle of the outer wall of the two pipe bodies. A second clamping strip is connected to the bottom end of the first clamping strip via a rotating assembly. A second fixing block is fixedly connected to the front end of the second clamping strip. Tightening blocks are connected to the top ends of the two second fixing blocks via a connecting assembly.

The outermost side of the sealing ring is provided with a weather-resistant rubber layer, the inner side of which is provided with a heat-insulating rubber layer, the inner side of which is provided with an expanding rubber layer, and the inner side of which is provided with a reinforcing fiber layer.

[0009] Furthermore, the rotating assembly includes a fixed rod fixedly connected to the rear end of the first pressing bar, a rotating plate rotatably connected to the outer wall of the fixed rod, and the rear end of the second pressing bar fixedly connected to the bottom end of the rotating plate.

[0010] Furthermore, a rectangular groove is formed at the rear end of the first pressing strip corresponding to the outer wall of the rotating plate, and the size of the rectangular groove is the same as the size of the rotating plate.

[0011] Furthermore, the connecting assembly includes a rotating column rotatably connected to one end of each of the two second fixed blocks, a lead screw fixedly connected to the top of the rotating column, and the inner wall of the screw block being threadedly connected to the upper side of the outer wall of the lead screw.

[0012] Furthermore, fixing strips are fixedly connected to both the left and right sides of the outer wall of the screw block to facilitate hand-tightening of the screw block.

[0013] Furthermore, the sealing ring is primarily made of rubber.

[0014] 1. In this utility model, tightening the screw block on the screw rod can press the first and second clamping strips together, thereby pressing the pipe connection.

Detailed Implementation

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-3 This utility model provides an embodiment of a sealing device for building electrical pipes, comprising two pipe bodies 1, which are aligned with each other at opposite ends. A first clamping strip 2 is installed on the upper side of the middle of the outer wall of each pipe body 1. (Referring to...) Figure 4 The first pressing strip 2 is fixedly connected to a fixing rod 3 at its rear end. A rotating plate 4 is rotatably connected to the outer wall of the fixing rod 3. A second pressing strip 5 is fixedly connected to the bottom end of the rotating plate 4. A second fixing block 7 is fixedly connected to the left and right sides of the front end of the second pressing strip 5. A rotating column 8 is rotatably connected to one end of the two second fixing blocks 7. A screw rod 9 is fixedly connected to the top of the rotating column 8. A screw block 10 is threadedly connected to the upper side of the outer wall of the screw rod 9. A first fixing block 6 is fixedly connected to the front end of the first pressing strip 2. A rectangular groove is opened on the outer wall of the rotating plate 4 at the rear end of the first pressing strip 2. The size of the rectangular groove is the same as the size of the rotating plate 4. Fixing strips 11 are fixedly connected to the left and right sides of the outer wall of the screw block 10 to facilitate the screw block 10 being turned by hand.

[0026] Specifically, the first pressing strip 2, the rotating plate 4, the second pressing strip 5, the first fixing block 6, the second fixing block 7, the rotating column 8, the screw rod 9, the screw block 10, and the fixing strip 11 together form a sealing device. The fixing strip 11 allows the operator to easily screw the screw block 10 by hand. The second fixing blocks 7 are respectively fixed with connecting rods, and the rotating column 8 rotates on the connecting rods on both sides.

[0027] Reference Figure 1 , Figure 5 and Figure 6The sealing ring 12 is fitted on the inner wall of the connection between the two pipe bodies 1 at opposite ends. The outermost side of the sealing ring 12 is provided with a weather-resistant rubber layer 13. A heat-insulating rubber layer 14 is provided on the inner side of the weather-resistant rubber layer 13. An expansion rubber layer 15 is provided on the inner side of the heat-insulating rubber layer 14. A reinforcing fiber layer 16 is provided on the inner side of the expansion rubber layer 15. The sealing ring 12 is mainly made of rubber.

[0028] Specifically, the weather-resistant rubber layer 13 is made of EPDM rubber, the heat-insulating rubber layer 14 is made of neoprene rubber, the expandable rubber layer 15 is made of water-swellable rubber, and the reinforcing fiber layer 16 is made of glass fiber. The weather-resistant rubber layer 13 is made of EPDM rubber, which has excellent ozone resistance, UV resistance, and aging resistance. EPDM rubber can maintain its physical properties for a long time, preventing cracking and aging of the sealing ring, thus extending its service life. The heat-insulating rubber layer 14 is made of neoprene rubber, which has good weather resistance, chemical corrosion resistance, and heat insulation properties. In the sealing ring 12, the heat-insulating rubber layer 14 can effectively block the transfer of external heat, preventing high temperatures from damaging the electrical equipment and wiring inside the pipeline. While mitigating adverse effects, it also resists the erosion of some chemicals. The expanding rubber layer 15 is water-swellable rubber, which expands in volume when in contact with water or a humid environment. The expanding rubber layer 15 can effectively prevent the leakage of groundwater or condensate inside the pipe. The water-swellable rubber can automatically fill the tiny gaps that may appear due to water intrusion, enhancing the sealing effect. The reinforcing fiber layer 16 is made of glass fiber, which has high strength and tensile strength. In the structure of the sealing ring 12, it can provide support for the sealing ring 12 and enhance the structural integrity of the sealing ring 12. When the pipe is deformed due to external pressure or changes in internal fluid pressure, the reinforcing fiber layer 16 can prevent the rubber ring from deforming excessively, ensuring the stability of the sealing effect.

[0029] Working principle: Two pipe bodies 1 are connected together, and a sealing ring 12 is fitted at the internal connection. The first clamping strip 2 is tightly attached to the connection of the pipe body 1. The rotating plate 4 is rotated, which drives the second clamping strip 5 to rotate. The rotating column 8 is rotated, which drives the screw 9 to rotate. The screw 9 passes through the middle of the first fixing block 6. The fixing strip 11 is tightened to press the bottom of the fixing block 10 tightly against the upper side of the first fixing block 6. The first fixing block 6 and the second fixing block 7 are pressed together, thereby pressing the connection of the pipe body 1 with the first clamping strip 2 and the second clamping strip 5 to prevent the connection of the pipe body 1 from loosening. The weather-resistant rubber layer 13 is in direct contact with the external environment or the outer shell of the pipe device, and mainly plays a protective role, resisting physical wear and chemical corrosion. It may also be used to prevent impurities from entering the internal structure. The heat-insulating rubber layer 14 prevents high temperature from adversely affecting the electrical equipment and wiring inside the pipe. The expanding rubber layer 15 can automatically fill the tiny gaps that may appear due to moisture intrusion, enhancing the sealing effect. The reinforcing fiber layer 16 prevents the rubber ring from being excessively deformed, ensuring the stability of the sealing effect.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
