Description

TECHNICAL FIELD

[0001] The utility model relates to the field of water supply and drainage pipeline construction equipment, and concretely relates to a water supply and drainage pipe connecting and fixing structure for building construction. BACKGROUND

[0002] In the field of building, the water supply and drainage system is the key infrastructure to ensure the normal operation of the building and the comfort of the residents' life, which covers residential buildings, commercial buildings, industrial plants and various public facilities and other scenes. In the residence, the water supply and drainage pipelines of the kitchen and the bathroom are directly related to the convenience of the residents' daily water use and the cleanliness of the living environment; the stable operation of the water supply and drainage system in public facilities such as hospitals and schools is related to the public health and the normal teaching and medical order. Under normal circumstances, most scenes have high requirements for the sealing of the water supply and drainage pipeline connection, however, in some temporary building construction sites, such as temporary water supply and drainage of simple sheds, due to the short use cycle, the sealing requirement is relatively low; some temporary water supply and drainage pipelines for agricultural irrigation have low requirements for water quality, and a small amount of leakage has little effect on the overall irrigation, so the sealing requirement is also poor.

[0003] Based on the above-mentioned part of the scene summary, the traditional water supply and drainage pipe connection fixing adopts rigid connection components, such as fixed size metal pipe clamps or plastic connecting pieces. The inner diameter of these components is fixed, and once the water supply and drainage pipeline with deviation from the standard specification is encountered, it is difficult to adapt. For example, in the temporary building construction site, due to material procurement restrictions or on-site emergency needs, various non-standard pipe diameters of pipe materials may appear, and the traditional fixing device cannot be flexibly adjusted, or the installation is difficult, or the fixing effect is poor after installation, and problems such as pipe loosening and displacement are prone to occur. In the temporary pipeline laying for agricultural irrigation, the pipe diameters of irrigation pipelines from different sources are uneven, and the traditional way needs to prepare connecting pieces of various specifications, which is complicated and high in cost, and cannot guarantee the stable connection of each pipe diameter.

In the installation process, the water supply and drainage pipeline is inserted into the inner wall of silica gel tube 4, and the end surface of the water supply and drainage pipeline is kept in the middle position inside silica gel tube 4.

[0030] The two end surfaces of connecting hoop 3 are symmetrically welded with threaded column 31, and the inner wall of threaded column 31 is flush with the inner wall of connecting hoop 3, so as to prevent the silica gel tube 4 located on the inner side from being wrinkled. The outer side of threaded column 31 is provided with a round table extrusion block 32 through threaded cooperation, and a threaded groove is formed in the end surface of threaded column 31.

The sealing hoop 6 externally supports the gear rod 52 and other connected components, thereby increasing the service life and sealing property of the gear rod 52 and other components.

[0040] Meanwhile, the cross section of the sealing hoop 6 is L-shaped, and the inner wall of the sealing hoop 6 is provided with an O-shaped ring 62, further increasing the sealing property of the outer support of the sealing hoop 6.
