Abstract
The invention discloses a water pipe expansion joint. A water pipe is connected in a sealed mode through an expansion joint from inside to outside, an expansion sleeve is uniformly expanded outwards through screwing in of a screw, and then the water pipe is tightened through an external hoop ring. Compared with a traditional clamping hoop, the water pipe expansion joint has a better circular degree and is convenient to install.
Description
Technical field
The present invention relates to a kind of water pipe expansion pipe, belong to the pipe fitting field.
Background technique
Traditional water pipe is generally undertaken fastening by clip, but due to problems such as incompressibility such as leather hoses, thus sealing can't guarantee fully, and traditional clip is because the problem of modern crafts, the circularity of clip also can't guarantee fully.
Summary of the invention
The object of the invention is to: a kind of technological scheme that can address the above problem is provided.
The present invention realizes by the following method:
A kind of water pipe expansion pipe, described expansion pipe comprises joint body, expansion bolt, inipple and garter spring, described joint body is a reducing round tube shape structure, described joint body inwall is provided with screw thread, described joint body is processed with some roads groove from the shorter end of diameter to the long end of diameter, the length that is shorter in length than joint body of described groove, described inipple are arranged on the long end of the local diameter of joint;
The fluted part outer wall of described joint body processing also is processed with some annular grooves, and described garter spring is socketed in described groove;
Described expansion bolt is screw rod, and described screw rod one end is processed with interior hexagonal bayonet socket, and described screw rod center is processed with the through hole that diameter is L, and described screw rod is threaded in joint body by the joint body inwall.
As further innovation of the present invention, described garter spring adopts elastic metallic to make.
As further innovation of the present invention, described elastic metallic is cast steel.
As further innovation of the present invention, described some roads groove is symmetrical arranged with respect to the joint body axle center.
As further innovation of the present invention, described inside grooves is filled with rubber.
Beneficial effect
1. the present invention is connected and sealed to water pipe by interior expansion pipe outward by one, by screw, screw in expansion sleeve is expanded uniformly outwardly, then outside garter spring is strained water pipe, and than traditional clip, the present invention has the convenience of better circularity and installation.
2. garter spring of the present invention is used elastic metallic to make, and prevents that overexpansion from stretching and the garter spring that produces damages and reveals.
3. uniformity and the sealing in order to expand, expansion slot of the present invention is for being symmetrical arranged uniformly.
4. in order to be that sealing is better, the present invention also is provided with rubber in the inside grooves of garter spring, coordinates and has improved sealing by rubber and outside clip.

Fig. 2 is erection drawing of the present invention.
Fig. 3 is the schematic diagram of expansion bolt of the present invention.
Fig. 4 is the transverse cross-sectional view of expansion pipe channel portions of the present invention.
In figure: 1, garter spring; 2, groove; 3, joint body; 4, inipple.
Embodiment
Below in conjunction with accompanying drawing, be described further
A kind of water pipe expansion pipe, described expansion pipe comprises joint body 3, expansion bolt, inipple 4 and garter spring 1, described joint body 3 is a reducing round tube shape structure, described joint body 3 inwalls are provided with screw thread, described joint body 3 is processed with some roads groove 2 from the shorter end of diameter to the long end of diameter, the length that is shorter in length than joint body 3 of described groove 2, described inipple 4 are arranged on the long end of the local diameter of joint;
The part outer wall that described joint body 3 is processed with groove 2 also is processed with some annular grooves, and described garter spring 1 is socketed in described groove;
Described expansion bolt is screw rod, and described screw rod one end is processed with interior hexagonal bayonet socket, and described screw rod center is processed with the through hole that diameter is L, and described screw rod is threaded in joint body 3 by joint body 3 inwalls;
Described garter spring 1 adopts elastic metallic to make;
Described elastic metallic is cast steel;
Described some roads groove 2 is symmetrical arranged with respect to joint body 3 axle center;
Described inside grooves is filled with rubber.
In use, at first by expansion bolt 5 from joint body 3, taking out, garter spring 1 is enclosed within on water pipe to be connected, afterwards water pipe is nested into to the expansion head end that is provided with groove 2, afterwards garter spring 1 is moved in the groove of expansion head end setting, then expansion bolt is screwed in joint body 3, by rotation expansion bolt 5, the expansion head end of joint body is constantly expanded, by with the coordinating of garter spring 1, water pipe is tightly connected, finally by the inipple of joint body 4 and the first-class connection of the fire hose, current flow out by the hole in the middle of expansion bolt.
