Technical Field

[0001] This utility model belongs to the field of boiler connector technology, and particularly relates to a quick connector for an electric boiler. Background Technology

[0002] Electric boiler connectors are an important component of electric boiler systems. They are responsible for connecting the electric boiler to the heating pipes, ensuring the efficient and safe transmission of heat energy. Electric boiler connectors are key components that connect the electric boiler to the heating system, allowing the heat energy generated by the electric boiler to be transmitted through pipes to the space or equipment that needs to be heated.

[0003] In the prior art, patent CN214662649U discloses a novel water inlet connector for an electric heating boiler. This technical solution reinforces the locking block through the cooperation of various components, making it more resistant to slippage and easier to disassemble compared to traditional connectors where both ends are threaded to the water pipe. However, this quick connector cannot change the direction of the water flow during use, making it inconvenient to adapt to the direction of the pipeline system, thus increasing the installation difficulty of the pipeline system. Utility Model Content

[0004] This utility model provides a quick connector for an electric boiler, aiming to solve the problem that quick connectors for electric boilers cannot change the direction of the water flow during use and are not convenient for adaptive adjustment according to the direction of the pipeline system.

[0006] The other end of the connecting sleeve is detachably provided with a second connecting plate. The surface of the second connecting plate is threaded with a number of second connecting bolts. The other end of the connecting sleeve is provided with a number of threaded holes that are adapted to the second connecting bolts. An internal threaded cylinder is fixedly connected inside the second connecting plate. The internal threaded cylinder is threaded with a threaded tube. The other end of the threaded tube is connected to a U-shaped tube. The other end of the U-shaped tube is connected to an external connecting tube. The surface of the external connecting tube is provided with a second engaging groove.

[0007] Preferably, a sealing ring is provided between the second connecting plate and the other end of the mating connecting sleeve.

[0008] Preferably, the other end of the connecting end is connected to a connecting pipe, and the surface of the connecting pipe is provided with a first engaging groove.

[0009] Preferably, a first connecting plate is fixedly connected to the side wall of the connecting end, and the first connecting plate is detachably connected to one end face of the mating connecting sleeve by a plurality of first connecting bolts.

[0010] Preferably, a temperature sensor is provided on the top of the mating connection sleeve, and the sensing end of the temperature sensor extends into the inner cavity of the mating connection sleeve.

[0011] Preferably, a lifting ring is fixedly connected to the top of the docking sleeve.

[0012] Beneficial effects

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] After the threaded pipe is connected to the internal threaded cylinder, and multiple second connecting bolts are connected to the threaded holes at different positions, the orientation of the external pipe can be adjusted. This facilitates adaptive adjustment according to the boiler's piping system, which is beneficial for the installation and operation of the boiler piping. The second locking groove improves the locking stability after the external pipe is connected to the external pipe, and the temperature sensor facilitates the detection of water temperature, which is beneficial for the operation of the boiler.
