[0018] It is necessary to point out here that the following specific embodiments are only used to further illustrate the application, and cannot be understood as limiting the protection scope of the application, and the skilled in the art can make some non-essential improvements and adjustments to the application according to the above application content.

[0019] Embodiment

[0020] As Figure 1 - Figure 4 As shown in the figure, an energy-saving water supply and drainage pipeline connecting device for building engineering construction includes a connecting sleeve 1, which is in a circular tube structure. An anti-skid handle 2 is fixedly sleeved on the outer wall of the middle section of the connecting sleeve 1. The anti-skid handle 2 allows the user to hold the connecting sleeve 1 through the anti-skid handle 2, thereby avoiding the rotation of the connecting sleeve 1 in the palm of the user when the connecting sleeve 1 is under stress, and facilitating the subsequent connection of the external water supply and drainage pipeline to the end of the connecting sleeve 1.

[0021] An annular flange 3 is integrally formed on the inner wall of the middle section of the connecting sleeve 1. A bellows 4 is arranged in the connecting sleeve 1. Sealing pads 5 are fixedly connected to the two ends of the bellows 4. The sealing pads 5 are in an annular structure, and the outer side wall of the sealing pads 5 is in sliding contact with the inner wall of the connecting sleeve 1. The inner diameter of the sealing pads 5 is set according to the inner diameter of the water supply and drainage pipeline to be connected. After the end of the water supply and drainage pipeline is fixed in the connecting sleeve 1, the sealing pads 5 can be fitted to the end of the water supply and drainage pipeline to seal the end of the water supply and drainage pipeline. The inner diameter of the sealing pads 5 is set according to the inner diameter of the water supply and drainage pipeline to be connected, which can avoid the impact of the water flow in the water supply and drainage pipeline on the sealing pads 5 when the water flow passes through the sealing pads 5, affecting the fitting degree of the sealing pads 5 and the end of the water supply and drainage pipeline, and causing water leakage at the connection between the water supply and drainage pipeline and the sealing pads 5.

[0022] Two sealing pads 5 are arranged on the two sides of the annular flange 3. A plurality of slide rods 6 are annularly distributed on one side of the sealing pads 5 close to the annular flange 3. One end of the slide rods 6 is fixed to the sealing pads 5, and the other end of the slide rods 6 is fixedly connected to a gasket 7. One end of the slide rods 6 connected to the gasket 7 is slidably sleeved with a slide pipe 8. The end of the slide pipe 8 away from the slide rods 6 is fixed to the annular flange 3. A spring 9 is arranged in the slide pipe 8. One end of the spring 9 is fixed to the end wall of the slide pipe 8, and the other end of the spring 9 is fixed to the gasket 7. The spring 9 is in a compressed state after the water supply and drainage pipeline is connected. When the water supply and drainage pipeline produces relative displacement with the connecting sleeve 1 due to vibration caused by water flow impact, the spring 9 can push the slide rods 6 to slide outward from the slide pipe 8 under the elastic force of the spring 9, thereby pushing the sealing pads 5 to move synchronously, compensating for the displacement of the water supply and drainage pipeline, and making the sealing pads 5 always fit the end of the water supply and drainage pipeline, thereby avoiding water leakage at the connection between the end of the water supply and drainage pipeline and the bellows 4, and causing water resource waste.

[0023] The connecting sleeve 1 is provided with clamping structures at both ends for fixing the water supply and drainage pipes, the clamping structures comprise a joint 10 fixedly connected to the end of the connecting sleeve 1, the joint 10 is in the shape of a circular truncated cone, a plurality of contraction grooves 13 are formed in the side wall of the joint 10 away from the end of the connecting sleeve 1, a tapered external thread 12 is formed on the outer surface of the joint 10, and the clamping structures further comprise a locking ring 14 sleeved on the outer surface of the joint 10 and screwed with the joint 10 through the tapered external thread 12, when the water supply and drainage pipes are connected, the end of the water supply and drainage pipes can be inserted into the joint 10, and the water supply and drainage pipes are slid into the connecting sleeve 1 until the end of the water supply and drainage pipes extrudes the spring 9 to the maximum compression amount of the spring 9, then the user screws the locking ring 14 to the end of the joint 10 close to the connecting sleeve 1, the side wall of the joint 10 is extruded to contract along the contraction grooves 13 through the locking ring 14, and the water supply and drainage pipes are clamped and fixed in the joint 10, so that the connection of the water supply and drainage pipes is completed;

[0024] The inner diameter of the joint 10 away from the end of the connecting sleeve 1 is not less than the outer diameter of the water supply and drainage pipes to be connected, the water supply and drainage pipes can be conveniently inserted into the joint 10 from the end of the joint 10 away from the connecting sleeve 1, the anti-skid lines 11 are formed on the inner wall of the joint 10, the friction between the inner wall of the joint 10 and the outer surface of the water supply and drainage pipes can be increased, and relative sliding between the end of the water supply and drainage pipes and the joint 10 caused by water flow impact is avoided as much as possible.

[0025] It should be noted that the water supply and drainage pipe connecting device for energy-saving building engineering construction is used, the ends of two water supply and drainage pipes to be connected are respectively inserted into the joints 10 at both ends of the connecting sleeve 1, and the water supply and drainage pipes are slid into the connecting sleeve 1 until the ends of the water supply and drainage pipes extrude the spring 9 to the maximum compression amount of the spring 9, then the user screws the locking ring 14 to the end of the joint 10 close to the connecting sleeve 1, the side wall of the joint 10 is extruded to contract along the contraction grooves 13 through the locking ring 14, and the water supply and drainage pipes are clamped and fixed in the joint 10, so that the connection of the water supply and drainage pipes is completed, since the spring 9 is in a compressed state after the water supply and drainage pipes are connected, when the water supply and drainage pipes vibrate due to water flow impact and relatively displace the connecting sleeve 1, the spring 9 can push the sliding rod 6 to slide out of the sliding pipe 8 under the elastic force of the spring 9, so as to push the sealing gasket 5 to move synchronously, the displacement of the water supply and drainage pipes is compensated, the sealing gasket 5 always adheres to the end of the water supply and drainage pipes, water leakage at the connection between the end of the water supply and drainage pipes and the corrugated pipe 4 is avoided as much as possible, the problem of water resource waste is solved, and the device is more energy-saving and environment-friendly.

[0026] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be noted that, for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
