[0002] Building pipelines are an important part of building engineering, used to transport gases, liquids or fluids containing solid particles. They are widely used in multiple systems inside buildings, such as water supply, drainage, heating, gas supply, and fire protection. Pipe fittings are key components for ensuring the integrity and function of the pipeline system, and can improve the installation efficiency and sealing effect of pipeline connections.

[0003] A search revealed Chinese Patent Publication No. CN216239009U, which discloses a fastener for building construction. The fastener includes a long bolt, an internal thread, and a rubber plug. When connecting two metal pipes, the two pipes are first rotated into the connecting holes at the front and rear ends of the main housing, respectively, and simultaneously engaged with the internal thread until they reach the interior of the fastener. The long bolt then secures the fastener, achieving a double-fixing effect and ensuring a more secure fit. The rubber plug also provides waterproofing, preventing rust buildup inside the fastener and making disassembly easier while protecting the quality of the metal pipes.

[0004] In actual use, when the aforementioned connectors are used to rotate and install one side of the metal pipe, it is necessary to rotate the entire metal pipe to be installed, or rotate the connector and the installed metal pipe. If the metal pipe to be installed is long or heavy, it will increase the installation difficulty and thus affect the installation efficiency. Therefore, a high-strength connector for building engineering is proposed to solve the above problems. Utility Model Content

[0032] 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.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a high-strength connector for building engineering, comprising a right connecting pipe 1, a sealing bearing 2 fixedly connected to the left side surface of the right connecting pipe 1, the outer left surface of the sealing bearing 2 being fixedly connected to the left side surface of the right connecting pipe 1, a connecting cylinder 3 fixedly connected inside the sealing bearing 2, which, when the connecting cylinder 3 rotates, drives the inner ring of the sealing bearing 2 to rotate synchronously, the inner diameter of the connecting cylinder 3 being the same as the diameter of the right connecting pipe 1, thus avoiding obstruction of pipe insertion; a sealing rubber ring 4 fixedly connected to the center of the connecting cylinder 3, which, when both pipes are inserted into the connector, can squeeze the sealing rubber ring 4. The pressure causes the sealing rubber ring 4 to deform and seal the connection between the two pipes, improving the sealing effect and reducing leakage. The left connecting pipe 5 is fixedly connected to the left side surface of the connecting cylinder 3. The right connecting pipe 1 and the left connecting pipe 5 are the same size. The left connecting pipe 5 is rotatably connected to the right connecting pipe 1 through the cooperation of the sealing bearing 2 and the connecting cylinder 3. The outer wall surfaces of the right connecting pipe 1 and the left connecting pipe 5 are provided with anti-slip grooves 11. The anti-slip grooves 11 can increase the friction between the outer wall of the right connecting pipe 1 and the left connecting pipe 5 and the user's palm, reducing slippage during the twisting process. The inside of the right connecting pipe 1 and the left connecting pipe 5 is fixedly connected with internal threads 7.

[0034] After inserting the two pipes into the right connecting pipe 1 and the left connecting pipe 5 from the left and right sides of the connector respectively, the right connecting pipe 1 and the left connecting pipe 5 can be rotated separately so that the internal thread 7 matches the pre-set external thread on the outside of the pipe for threaded connection. This allows the pipes to enter the connector for connection and installation when the operator screws the right connecting pipe 1 and the left connecting pipe 5, avoiding the need to rotate long and heavy pipes, which would affect the efficiency of connection and installation.

[0035] Reference Figures 4-6A reinforcing tube 6 is fixedly connected to the left end of the right connecting pipe 1. The reinforcing tube 6 is sleeved on the outside of the sealing bearing 2 and the left connecting pipe 5. The reinforcing tube 6 can improve the connection strength at the connection between the right connecting pipe 1 and the left connecting pipe 5, reduce the bending between the left connecting pipe 5 and the right connecting pipe 1, and avoid affecting the connection and sealing effect of the pipe. An annular groove 8 is opened on the inner wall surface of the left side of the left connecting pipe 5. A sealing ring 9 is fixedly connected inside the annular groove 8. The right side surface of the sealing ring 9 is fixedly connected to the inner wall surface of the right side of the annular groove 8. The inner diameter of the sealing ring 9 is larger than the inner diameter of the left connecting pipe 5. The larger diameter sealing ring 9 can avoid obstructing the insertion of the pipe.

[0036] Reference Figures 4-6 A compression unit 10 is provided on the left side of the left connecting pipe 5, and an annular groove 8, a sealing ring 9, and a compression unit 10 are also provided on the right side of the right connecting pipe 1. This allows for sealing of the gap between the pipe entering the right connecting pipe 1 and the right connecting pipe 1. The compression unit 10 includes an annular threaded groove 101, which is formed on the left side surface of the left connecting pipe 5. A threaded cylinder 102 is threadedly connected inside the annular threaded groove 101. When the threaded cylinder 102 rotates, it can move linearly in the left and right directions under the limitation of the annular threaded groove 101. An extrusion cylinder 103 is fixedly connected to the left side of the inner part of the 2. The extrusion cylinder 103 is located directly to the left of the sealing ring 9. The inner diameter of the extrusion cylinder 103 is larger than the inner diameter of the left connecting pipe 5. The outer diameter of the extrusion cylinder 103 is the same as the outer diameter of the sealing ring 9. When the threaded cylinder 102 moves, it can drive the annular threaded groove 101 to move synchronously. When the threaded cylinder 102 moves to the right, it will squeeze the sealing ring 9, causing the sealing ring 9 to be squeezed and deformed. A handle 104 is fixedly connected to the left side surface of the threaded cylinder 102. The user can drive the threaded cylinder 102 to rotate through the handle 104.

[0037] After the pipe is screwed into the connector, the user can rotate the handle 104 to rotate the threaded cylinder 102, causing the threaded cylinder 102 to move into the annular threaded groove 101, which in turn causes the extrusion cylinder 103 to move towards the sealing ring 9, extruding the sealing ring 9 and sealing the gap between the outer wall of the pipe and the connector, preventing rainwater from entering the connector through the gap.

[0038] Working principle: Insert two pipes into the left connecting pipe 5 and right connecting pipe 1 from the left and right ends of the connector, respectively. Then, rotate the right connecting pipe 1 and left connecting pipe 5 respectively, so that the pre-set external thread on the outside of the pipe engages with the internal thread 7 to complete the threaded connection. This allows the pipe to enter the connector for installation. When both pipes are inside the connector, the sealing rubber ring 4 can be squeezed to seal the connection between the two pipes, improving the leak-proof effect. After the connection is completed, rotate the handle 104 to rotate the threaded cylinder 102, causing the threaded cylinder 102 to move into the annular thread groove 101. This moves the extrusion cylinder 103 to move the sealing ring 9, causing the sealing ring 9 to deform and seal the gap between the pipe and the connector, preventing rainwater from entering.

[0039] 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.
