Description

Technical Field

[0001] The utility model relates to the technical field of galvanized pipes, in particular to a galvanized pipe which is convenient and quick to connect. Background Art

[0002] Galvanized steel pipes are divided into cold-dip galvanized steel pipes and hot-dip galvanized steel pipes. Cold-dip galvanized steel pipes have been banned, while the latter are temporarily recommended by the state. In the 1960s and 1970s, developed countries in the world began to develop new pipes and gradually banned galvanized pipes. China's Ministry of Construction and other four ministries also issued a document to ban the use of galvanized pipes as water supply pipes from 2000. Galvanized pipes are rarely used for cold water pipes in newly built communities, and some communities use galvanized pipes for hot water pipes. Hot-dip galvanized steel pipes are widely used in fire protection, electricity and highways.

[0003] During the use of galvanized pipes, due to the limited length of the pipeline, a connecting structure is required for subsequent use. Galvanized pipes usually cannot be connected quickly, which will cause certain inconveniences during use, thus affecting the efficiency of installation and connection. Based on this, we propose a galvanized pipe that is easy to connect and quick to connect. Utility Model Content

[0021] The working principle of the above technical solution is as follows: when in use, firstly, the outer side threads of multiple galvanized pipes 1 containing threaded strips 12 are connected and installed with connectors 9, and connectors 9 are rotated by clamping the clamping joint 8 with a wrench, so that connectors 9 are installed on the outer side of galvanized pipe 1 under the action of threaded strips 12, and at the same time, one end of connectors 9 is against one side of sealing gasket 10, and a reaction force is applied under the action of elastic deformation of sealing gasket 10, so that connectors 9 are tightly attached to the outer side of galvanized pipe 1. During installation, connectors 9 are preset on the outer side of galvanized pipe 1 to reduce installation and use, and then during installation, only one end of sealing cone 15 of another galvanized pipe 1 needs to be docked with the inside of connector 9, so that limit strip 4 docks with limit groove 11 and slides in, and finally sealing cone 15 docks with the inner side of sealing cone 2 14, and finally bolts are inserted into bolt hole 2 7 and bolt hole 1 6 to fix. The scheme has a tight connection, which is convenient for rapid connection and installation of larger pipelines and improves efficiency.

[0022] In another embodiment, Figure 1-Figure 4 As shown, the specification size of sealing cone 1 5 is matched with the specification size of sealing cone 2 14 .

[0023] Sealing cone 15 can be docked on the inner side of sealing cone 214 to facilitate sealing, so that the structure is tightly connected, and one side of sealing cone 214 is tightly fitted to the outer side of one end of galvanized pipe 1 after being fixed, and the sealing between sealing cone 15 and sealing cone 214 is firmly sealed under the extrusion of the pipeline connection, thereby increasing the sealing of the connection.

[0024] In another embodiment, Figure 1-Figure 4 As shown, the specifications and dimensions of the four bolt holes 6 are matched with the specifications and dimensions of the bolt holes 2 7 , and the positions of the bolt holes 1 6 correspond to the positions of the bolt holes 2 7 .

[0025] Inserting bolts into bolt hole 1 6 and bolt hole 2 7 can ensure a stable connection between the support ring 2 and the retaining ring 3. The overall structure has a good use effect, is easy to connect and install tightly, and stabilizes the structural strength.

[0026] In another embodiment, Figure 1-Figure 4 As shown, the specification and size of the limiting groove 11 are matched with the specification and size of the limiting strip 4.

[0027] The butt joint between the limiting strip 4 and the limiting groove 11 facilitates the reduction of sliding, so that the structure can be quickly positioned during installation, and reduces rotation during connection, thereby increasing the structural strength.

[0028] In another embodiment, Figure 3 and Figure 5 As shown, the soft sealing edge 17 is movably sleeved on the outer side of the second galvanized pipe 15 , and the specification and size of the rubber sealing ring 20 are matched with the specification and size of the second galvanized pipe 15 .

[0029] The soft sealing edge 17 facilitates the two ends of the galvanized pipe 15 to be sealed when the pipe sleeve 16 squeezes the two ends. After squeezing out the air, the two ends are sealed to increase the air tightness, which is convenient for increasing the air pressure adsorption force. The rubber sealing ring 20 facilitates the two ends of the galvanized pipe 15 to be stably connected, and has good performance.

[0030] In another embodiment, Figure 3 and Figure 5 As shown, the position of the hoop 18 corresponds to the position of the rubber ring 13, and a nut is threadedly connected to the outer side of the bottom end of the fastening bolt 19.

[0031] By setting the pipe sleeve 16, old galvanized pipes and galvanized pipes that need to be cut can be installed. The two galvanized pipes 15 are inserted into the pipe sleeve 16, and the opposite ends are located on both sides of the rubber sealing ring 20 and on the inner side of the rubber ring 13. Then the fastening bolts 19 are rotated to make the hoop 18 squeeze the pipe sleeve 16, and make the rubber ring 13 fit on the outside of the galvanized pipe 15, and the two ends are squeezed and fit on the outside of the rubber sealing ring 20. At this time, the two galvanized pipes 15 can be tightly fitted, and the installation efficiency is stabilized, the invariance of the connection to the old galvanized pipes is increased, the overall stability is good, and the connection and installation are quick.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
