Abstract

The invention provides a quick-change connector, and belongs to the technical field of machines. The quick-change connector solves the problems that after an existing quick-change connector is used for a long time, leakage is prone to being generated, and the connecting effect is not ideal. The quick-change connector comprises a barrel-shaped locking sleeve. A barrel-shaped locking framework is inserted and movably connected in the locking sleeve. A connecting pipe is inserted in the locking framework. A plurality of upper locking blocks capable of moving horizontally are arranged at the upper end of the locking framework. A pushing force spring is arranged between each upper locking block and the locking framework. First threaded teeth the same in tooth shape are arranged at the inner ends of the upper locking blocks. A plurality of first convex bodies are arranged on the inner side wall of the upper end of the locking sleeve, and the first convex bodies are located on the outer sides of the upper locking blocks. A first spring is arranged between the connecting pipe and the locking framework. The two ends of the first spring abut against the connecting pipe and the locking framework correspondingly. The quick-change connector has the beneficial effects of being good in sealing effect and connecting effect and long in service life.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a joint, in particular to a quick-change joint. Background technique [0002] At present, a water pump connector is usually provided at the water pump outlet to realize the connection between the water pump and the external equipment, which solves the troublesome problem of connection between the water pump and the external equipment due to the mismatch of size, shape or thread. The interface between the water pump outlet and the water pump joint is generally fixed by threaded connection, and the interface is further sealed. When the angle of the water pump joint needs to be adjusted, the seal at the interface will inevitably be damaged. After the angle of the water pump joint is adjusted in place, the joint needs to be resealed, which is very troublesome. [0003] A water pump inlet and outlet quick connector disclosed in Chinese patent literature (application number: 2013206258...
