Abstract
Provided is a downpipe joint used on external walls of a building for connecting a plastic pipe and a metal pipe, the downpipe comprises a circular upper socket, a circular lower socket and a circular edge, the internal diameter of the circular upper socket is equal to or larger than the external diameter of the plastic pipe, the external diameter of the circular upper socket is equal to or smaller than the internal diameter of the metal pipe, the internal diameter of the circular edge is larger than or equal to the external diameter of the metal pipe. when in installation, the plastic pipe is inserted into the circular upper socket, the metal pipe is inserted into the lower socket and is enclosed by the circular edge. Such a joint effectively solves the problems that other substitutes is inconvenience in installation, is easy to be damaged and the metal pipe is easy to be corroded because of external water leakage etc. The downpipe joint provided has the effects of convenient installation, simple structure, durable use or beautiful shape etc.
Description
Technical field
The utility model relates to a kind of building component, relates in particular to a kind of plastic pipe of leader and special joint of metal tube of connecting.
Background technology
Owing to do not have this kind special joint in the past, adopt product replacements such as common plastics tube mostly, install very inconvenient; The joint leaks easily when rainy, causes the wall humidity, the wall mouldy cracking that makes moist easily, and joint damages problems such as metal tube easy-to-rust easily.
Summary of the invention
The utility model provides a kind of plastic pipe of leader and special joint of metal tube of connecting.Have easy for installation, simple in structure, the durable effect that waits attractive in appearance.
To achieve these goals, the technical solution adopted in the utility model is: a kind of leader joint, it is characterized in that by bellmouth on the circle, circular socket down and circle are formed along the limit, the internal diameter of bellmouth is equal to or greater than the plastic pipe external diameter on the circle, the circular external diameter of socket down is equal to or less than the metal tube internal diameter, and circular internal diameter along the limit is more than or equal to the metal tube external diameter.
Owing to adopted this kind joint, solved other substitutes effectively inconvenience, the easy damage and the outer problems such as metal tube corrosion that seep water and cause are installed.
Description of drawings
Fig. 1 is a sectional drawing of the present utility model;
Fig. 2 is a section installation drawing of the present utility model.
Among the figure: 1, bellmouth on the circle; 2, circular socket down; 3, circular along the limit.
The specific embodiment
The utility model is by bellmouth on the circle 1 and circular socket 2 down and circularly 3 form along the limit.The top plastic pipe inserts the last bellmouth of leader joint during installation; Following socket inserts the metal tube inside of leader below, and circle is just in time protected the metal tube end along the limit.After the installation as shown in Figure 2.Because circular upward the bellmouth external diameter is close with the metal tube internal diameter, certain taper is arranged, so easy for installation, also very firm again; Circle is protected the metal tube end along the limit, also better appearance.
Claims (4)
1. a leader joint is used for external wall and connects plastic pipe and metal tube, it is characterized in that by bellmouth on the circle, and circular socket down and circle are formed along the limit.
2. leader joint according to claim 1 is characterized in that the circular internal diameter of going up bellmouth is equal to or greater than the plastic pipe external diameter.
3. leader joint according to claim 1 is characterized in that the circular external diameter of socket down is equal to or less than the metal tube internal diameter.
4. leader joint according to claim 1 is characterized in that circular internal diameter along the limit is more than or equal to the metal tube external diameter.
