Detailed Description

The following further describes embodiments of the present invention with reference to the drawings.

As shown in fig. 1 to 4, the utility model relates to a filtering water guide pipe for buildings, which comprises two fixing plugs 4 arranged in parallel, wherein an inner pipe 3 and an outer pipe 1 are connected between the two fixing plugs 4, the inner pipe 3 and the outer pipe 1 are coaxially arranged, filter cotton 2 is arranged between the inner pipe 3 and the outer pipe 1, the filter cotton 2 is coarse filter cotton, a plurality of holes 5 are uniformly distributed on the pipe walls of the inner pipe 3 and the outer pipe 1 respectively, and the holes 5 achieve the purpose of water permeability when the product is used. The diameter of the holes 5 is 5-10 mm, preferably, the diameter of the holes 5 is 5 mm.

Further, in order to realize reliable insertion and fixation of the axial two ends of the inner pipe 3 and the axial two ends of the outer pipe 1, the fixed plug 4 comprises a chassis 4-3, and a fixed plug outer ring 4-1 and a fixed plug inner ring 4-2 are constructed on the surface of the chassis 4-3.

The axial two ends of the inner pipe 3 are respectively connected with the corresponding inner rings 4-2 of the fixed plugs, and the axial two ends of the outer pipe 1 are respectively connected with the corresponding outer rings 4-1 of the fixed plugs.

It can be understood that, in order to facilitate the reliable connection of the inner tube 3 and the outer tube 1, the inner ring 4-2 of the fixed plug and the outer ring 4-1 of the fixed plug form an annular slot respectively.

During specific production, the diameter of the outer pipe 1 is 25-50 cm, the diameter of the inner pipe 3 is 20-45 cm, and the diameter of the outer pipe 1 is larger than that of the inner pipe 3. Preferably, the outer tube 1 has a diameter of 30cm and the inner tube 2 has a diameter of 22.5 cm.
