Embodiment Construction

[0031] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0032] like Figures 1 to 3 As shown, a quick-change joint includes a cylindrical locking sleeve 1, and a cylindrical locking frame 2 is inserted in the locking sleeve 1. The locking sleeve 1 and the locking frame 2 are firmly connected in the circumferential direction. The side of the tight sleeve 1 is threaded to the limit screw 2 14, the outer wall of the locking frame 2 is provided with a strip-shaped limit groove 2c and the limit groove 2c is arranged parallel to the axial direction, and the inner end of the limit screw 14 is embedded in the limiting groove 2c.

[0033] A connecting pipe 3 is inserted into the locking frame 2, a spring 4 is arranged between the connecting pipe 3 and the locking frame 2, a shoulder 2b...

Abstract

The invention provides a quick-change connector, and belongs to the technical field of machines. The problems that an existing quick-change locking connector cannot be rapidly connected, after long-time use, the connecting effect is not ideal, and leakage is easily generated are solved. The quick-change connector comprises a locking sleeve, a locking framework is inserted in the locking sleeve, a connecting pipe is inserted in the locking framework, a first spring is arranged between the connecting pipe and the locking framework, the outer side of the locking framework is sleeved with a second spring, a plurality of upper locking blocks are arranged at the upper end of the locking framework, first threaded teeth are arranged at the inner ends of the upper locking blocks, the second spring can push the locking sleeve to move relative to the locking framework and enables the first threaded teeth to stretch out of the inner side wall of the locking framework, a plurality of lower locking blocks are hinged to the lower end of the locking framework, second threaded teeth are arranged at one ends of the lower locking blocks, outer threads are arranged on the outer side wall of the connecting pipe, and the second threaded teeth are engaged with the outer threads of the connecting pipe. According to the quick-change connector, the beneficial effects of being rapid in connection and good in connection effect are achieved.

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: 201320625...
