SUMMERY OF THE UTILITY MODEL

The utility model provides a simple structure guarantees that the temperature-sensing probe makes progress perpendicularly and the attach fitting of the good water pump of leakproofness.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: the connecting joint of the water pump comprises a shell, a pump body and a connecting joint, wherein the pump body is installed in the shell, the connecting joint is installed at the water inlet end of the pump body, a support is fixedly installed in the shell, the pump body is fixedly installed on the support, the connecting joint comprises a switching joint which is in threaded connection with the water inlet end of the pump body and a water inlet joint which is sleeved outside the switching joint, the water inlet joint is fixedly installed on the support, and a temperature probe is installed at the upper end of the water inlet joint.

The end part of the water inlet joint is integrally formed with a flange, and the flange is fixedly arranged on the support.

Wherein, be provided with first sealing washer between crossover sub with the pump body is intake and is held.

And a second sealing ring is arranged between the conversion joint and the water inlet joint.

The two second sealing rings are sleeved on the conversion joint in parallel.

And a third sealing ring is arranged between the temperature probe and the water inlet joint.

Compared with the prior art, the utility model discloses following beneficial effect has: the utility model discloses set up the end of intaking of crossover sub direct mount to water pump to make water inlet joint suit to crossover sub, make the temperature probe of installing on the water inlet connects upwards perpendicularly, guarantee the sealing performance of joint connection department simultaneously.
