Description

Technical Field

[0001] This utility model belongs to the field of drainage pipe connection technology, and in particular relates to a drainage pipe connection device for building engineering. Background Technology

[0002] During the construction of building projects, drainage pipe systems undertake key functions such as rainwater collection, sewage transportation, and flood control and drainage. Pipe connections are used to integrate prefabricated pipe sections into a complete drainage system. Common water supply and drainage pipes are often made of plastic, metal, concrete, and reinforced concrete. Most of them use flanges and gaskets or threaded bolts for connection. Moisture in the underground soil and corrosive media in sewage can quickly erode metal bolts and nuts, causing rust, loosening of fasteners, expansion of sealing gaps, and ultimately leakage. Simple flange connections are easily impacted by the water flow in the drainage pipe, which can cause the flange to loosen and lead to leakage. Utility Model Content

[0003] Based on the above background, the purpose of this utility model is to provide a drainage pipe connection device for building engineering.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A drainage pipe connection device for building engineering includes a pipe body and a connection component disposed between two pipe bodies; Both ends of the tube are frustum-shaped, with their diameters gradually increasing outwards. The outer ends of the tube are provided with first connecting blocks, which are circular rings. The connecting assembly includes a transition tube with connecting pipes at both ends. The outer side of the connecting pipe is a frustum shape with a diameter that gradually decreases in the axial direction. When the connecting pipe is inserted into the tube body, the outer side of the connecting pipe is in contact with the inner side of the tube body. The outer side of the transition tube is provided with a second docking block, and the second docking block and the docking tube are connected to a first connecting groove, and the end of the tube body is correspondingly inserted into the first connecting groove; The first docking block and the second docking block are connected by plugging in each other; The first docking block and the second docking block are connected to the outside of a clamp assembly.

[0005] Furthermore, the inner end side of the tube body is provided with a first sealing groove, and the outer side of the connecting tube is provided with a first sealing gasket, which is snapped into the first sealing groove.

[0006] Furthermore, the second mating block has a second sealing groove inside, and the second sealing groove is located on the periphery of the first connecting groove; a second sealing gasket is provided inside the second sealing groove.

[0007] Furthermore, a stop block is provided inside the second sealing groove; The second sealing gasket is made of silicone or rubber, and the unsealed second sealing gasket is teardrop-shaped. The connection end between the second sealing gasket and the second sealing groove is located on the side of the block away from the transition tube.

[0008] Furthermore, a first slot is provided on the side of the first docking block near the second docking block, and a first insert is provided on the second docking block, with the first insert correspondingly inserted into the first slot.

[0009] Furthermore, a second slot is provided on the side of the second docking block near the first docking block; a second insert is provided on the first docking block, and the second insert is inserted into the second slot.

[0010] Furthermore, the first insert and the second slot are concentrically arranged.

[0011] Furthermore, both the first docking block and the second docking block have slots on their outer periphery. The clamp assembly includes two semi-circular retaining rings, the two ends of which are respectively engaged with the retaining grooves of the first and second mating blocks; The two retaining rings are connected by bolts and nuts.

[0012] Furthermore, a protective cover is fitted onto the connecting end of the two retaining rings, and the protective cover is bonded to the retaining ring; The bolts and nuts are housed inside the protective cover.

[0013] This utility model has the following beneficial effects: 1. The first sealing gasket and the first sealing groove provide initial sealing at the connection position to prevent water leakage. When the connecting pipe is inserted into the pipe body, the end of the pipe body is inserted into the first connecting groove. The pipe body squeezes the second sealing gasket to completely fill the second sealing groove. The second sealing gasket is interference-fitted with the outside of the pipe body, which further improves the sealing performance of the connection position.

[0014] 2. The first and second mating blocks are snapped into the inside of the snap rings, with both ends of the snap rings snapped into the slots. The two snap rings are then fixed in place by bolts and nuts, thereby fixing the first and second mating blocks in place. Then, the protective cover is fitted onto the connecting ends of the two snap rings, and the end of the protective cover is glued to the outside of the snap rings, thereby fixing the protective cover to the end of the snap rings and protecting the bolts and nuts, thus better preventing the bolts and nuts from rusting.
