Technical Field
[0001] This utility model relates to the technical field of building water supply and drainage, specifically a pipe connection structure. Background Technology
[0002] The main purpose of building water supply and drainage is to meet people's needs for domestic, industrial, and fire-fighting water, and to ensure that water quality, quantity, and pressure meet the prescribed requirements. Building water supply systems introduce water from the town's water supply network or a self-supplied water source into the building, and then distribute it to various water points through distribution pipes to meet the needs of domestic, industrial, and fire-fighting water. During building water supply and drainage, pipe connections are required.
[0003] Existing pipe connection structures require compatibility with pipes of the same specifications for use. However, different pipe sizes are needed for different pipes, resulting in poor performance. Furthermore, pipe connections typically have filters installed to filter the drainage, but these filters are prone to accumulating dirt and are difficult to clean. Therefore, we propose a new pipe connection structure to address the aforementioned problems. Utility Model Content
[0004] The purpose of this utility model is to provide a pipe connection structure to solve the problems mentioned in the background art. Existing pipe connection structures need to be adapted to pipes of the same specification for use. When dealing with different pipes, different sizes of pipe connection structures are required, resulting in poor performance. In addition, filter screens are generally installed at pipe connections to filter drainage, but dirt easily adheres to the filter screens and are difficult to clean.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipe connection structure, including a fixed ring, side rings, and mounting holes. Both ends of the fixed ring are fixed with connecting sleeves, and the connecting sleeves at both ends of the fixed ring are provided with side rings. Positioning bolts are evenly installed on the surface of the side rings. Mounting rods are fixed on the surface of the fixed rings, and fastening nuts are connected to the ends of the mounting rods. Mounting holes are opened on the surface of the side rings. An inner support ring is fixed inside the side rings. Clamping rings are fixed at both ends of the fixed rings inside the connecting sleeves. Sealing gaskets are provided between the clamping rings and the connecting sleeves. A filter plate is fixed on one side of the inside of the fixed rings, and filter holes are evenly opened on the surface of the filter plate. A groove is opened at the bottom of the fixed rings, and a sealing plug is installed at the bottom of the fixed rings.
[0006] Preferably, the side ring and the fixed ring are connected by a mounting rod and a fastening nut. The mounting rod and the positioning bolt are staggered, and there are six sets of both the mounting rod and the positioning bolt.
[0007] Preferably, the inner support rings at both ends of the side ring are engaged with the connecting sleeves at the ends of the fixed ring, and the surface of the side ring is fixedly connected to the pipe by positioning bolts.
[0008] Preferably, the end of the retaining ring is inclined, and the retaining ring is connected to the sealing gasket by adhesive bonding.
[0009] Preferably, the sealing gasket is composed of a rubber gasket body, an inner cavity, and a separator strip. The inner cavity is formed inside the rubber gasket body, and the separator strip is uniformly fixed in the inner cavity inside the rubber gasket body.
[0010] Preferably, the four corners of the sealing plug are connected to the slot below the fixing ring by threaded nails to form a snap-fit disassembly and installation connection, and one end of the slot is fitted to the surface of the filter plate.
[0011] Compared with the prior art, the beneficial effects of this utility model are: the pipe connection structure,
[0012] The structure can be adapted to pipes of different sizes by using retaining rings with inclined ends on the fixed ring, in conjunction with the inner support ring and sealing gasket inside the side ring. It can also be used with positioning bolts, mounting rods and fastening nuts to facilitate the use of the structure.
[0013] The groove below the fixing ring, combined with the use of a removable sealing gasket, makes it easy to remove the sealing gasket during cleaning, allowing the filter plate on the inner surface of the fixing ring to be cleaned through the groove, thus improving the convenience of cleaning the filter plate.
