Description

Technical Field

[0001] The utility model relates to the technical field of meter connectors, in particular to a meter connector which can be quickly installed. Background Art

[0002] A meter joint is a component that connects an instrument meter and a pipe. Its function is to facilitate installation and maintenance, and it also serves as a seal. It is usually used for the installation and maintenance of metering pipes. In the installation of water meters in residential households, meter joints are also required to connect the two ends of the water meter to the tap water pipe. Therefore, meter joints that can be installed quickly play an important role.

[0003] Conventional meter joints have some disadvantages. First, they have a simple structure and need to be disassembled and assembled with a wrench. They are not easy to install quickly and are prone to damage to water meters and pipes. Second, they have poor performance and poor practicality. Utility Model Content

[0004] The utility model aims to provide a meter connector which can be quickly installed to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a meter joint that can be quickly installed, comprising a main joint pipe and a water meter, the main joint pipes are respectively arranged at both ends of the water meter, one end of the inner wall of the main joint pipe is provided with a locking thread, and the surface of the locking thread is provided with a wear-resistant layer, both ends of the water meter are provided with pipe heads, and the outer wall of the pipe head is threadedly matched with the locking thread, and a rubber sealing ring is provided on one end of the inner wall of the main joint pipe corresponding to the pipe head.

[0006] By adopting the above technical scheme, one end of the main joint pipe can be twisted toward the pipe head so that the locking thread and the thread on the outer wall of the pipe head cooperate with each other, and the main joint pipe is locked on the pipe head. At the same time, when twisting the main joint pipe, the external thread is aligned with the internal thread, and then the main joint pipe and the secondary joint ring are tightened, so that the main joint pipe and the sealing sleeve are connected together, and the main joint pipe can be disassembled and assembled by holding the anti-slip sleeve. Since the anti-slip sleeve has a large area and anti-slip patterns on the surface, the friction between the hand and the main joint pipe is increased. Therefore, the main joint pipe can be installed between the water meter and the rubber sealing sleeve by hand, which is easy and quick to install.

[0007] The utility model is further configured as follows: an explosion-proof layer is arranged on the inner wall of the main joint pipe, and an antifreeze layer is arranged on the inner wall of the explosion-proof layer.

[0008] By adopting the above technical solution, the explosion-proof layer is made of PVC material to avoid the main joint pipe from bursting, which is beneficial to improving the service life of the main joint pipe. The antifreeze layer is made of hard polyurethane foam plastic material to avoid the phenomenon of water flow freezing in severe cold weather.

[0009] The utility model is further configured as follows: an anti-slip sleeve is arranged at one end of the outer wall of the main joint pipe, and an external thread is arranged at the other end of the outer wall of the main joint pipe.

[0010] The utility model is further configured as follows: a secondary joint ring is arranged on the side of the main joint pipe, and a rubber sealing sleeve is arranged on the outer wall of the secondary joint ring.

[0011] By adopting the above technical solution, the main joint pipe can be disassembled and assembled by holding the anti-slip sleeve. Since the anti-slip sleeve has a large area and anti-slip patterns on the surface, the friction between the hand and the main joint pipe is increased. Therefore, the main joint pipe can be installed between the water meter and the rubber sealing sleeve by hand.

[0012] The utility model is further configured as follows: an inner thread is provided at one end of the inner wall of the secondary joint ring, and the inner thread is threadably matched with the outer thread.

[0013] By adopting the above technical solution, when the main joint pipe is twisted, the external thread is aligned with the internal thread, and then the main joint pipe and the secondary joint ring are tightened, so that the main joint pipe and the sealing sleeve are connected together.

[0014] The utility model is further configured as follows: an inner hot melt adhesive layer is arranged at one end of the inner wall of the rubber sealing sleeve.

[0015] The utility model is further configured as follows: a hose is arranged on the side of the rubber sealing sleeve, and a rubber stacking ring is arranged on the outer wall of the hose.

[0016] By adopting the above technical solution, the hose passes through the water pipe, and one end of the hose can be hot-melted to form an inner hot-melt adhesive layer, and the hot-melted adhesive stains are accumulated into an annular adhesive pile ring.

[0017] The utility model is further configured as follows: an outer hot melt adhesive layer is arranged on the side of the adhesive stacking ring, and the outer hot melt adhesive layer is fixedly connected to the inner hot melt adhesive layer.

[0018] By adopting the above technical solution, one end of the inner wall of the rubber sealing sleeve is hot-melted to form an outer hot-melt adhesive layer, and the outer hot-melt adhesive layer is sheathed on the outside of the inner hot-melt adhesive layer through the rubber sealing sleeve, so that the rubber sealing sleeve and the hose are tightly adhered.

[0019] Compared with the prior art, the utility model has the following beneficial effects: easy and quick installation and good performance;

[0020] (1) One end of the main joint pipe can be twisted toward the pipe head so that the locking thread and the thread on the outer wall of the pipe head cooperate with each other, and the main joint pipe is locked on the pipe head. At the same time, when twisting the main joint pipe, align the outer thread with the inner thread, and then tighten the main joint pipe and the secondary joint ring, so that the main joint pipe and the sealing sleeve are connected together. In addition, the main joint pipe can be disassembled and assembled by holding the anti-slip sleeve. Since the anti-slip sleeve has a large area and anti-slip patterns on the surface, the friction between the hand and the main joint pipe is increased. Therefore, the main joint pipe can be installed between the water meter and the rubber sealing sleeve by hand, which is easy and quick to install.

[0021] (2) The wear-resistant layer is made of KNM anti-corrosion and wear-resistant pipe coating. The wear-resistant layer can form a high-hardness wear-resistant layer on the surface of the locked thread to avoid damage to the main joint pipe caused by disassembly and maintenance of the water meter. The antifreeze layer is made of hard polyurethane foam plastic material to avoid water flow freezing in severe cold weather and has good performance. BRIEF DESCRIPTION OF THE DRAWINGS
