Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
The technical scheme of the specific implementation of the utility model is as follows:
as shown in fig. 1 and 2, a quick connector locking mechanism includes a female connector and a male connector;
the female joint comprises a female valve body 2 with a first flow channel 1, two chutes 3 which penetrate through the peripheral wall of the female valve body 2 along the wall thickness direction of the female valve body 2 are arranged on the peripheral wall of one end, close to the male joint, of the female valve body 2, the two chutes 3 are symmetrically arranged along the axis of the female valve body 2, locking pins 4 are arranged in each chute 3, the locking pins 4 are perpendicular to the axis of the female valve body 2, the middle parts of the locking pins 4 are positioned in the female valve body 2, an unlocking ring 5 is sleeved at one end, close to the male joint, of the female valve body 2, an annular cavity 6 is reserved between the unlocking ring 5 and the female valve body 2, the annular cavity 6 is communicated with the chutes 3, a tightening ring 7 is arranged in the annular cavity 6, the tightening ring 7 is connected with the unlocking ring 5, the tightening ring 7 is positioned at one side, far away from the male joint, of the locking pins 4, and one end, far away from the locking pins 4, of the tightening ring 7 is connected with a tightening spring 8, two ends of the locking pin 4 respectively extend into the annular cavity 6 and are tightly attached to the end face of the tightening ring 7;
the male connector comprises a male valve body 10 with a second flow passage 9, an annular clamping table 11 which can be matched and locked with the locking pin 4 is arranged on the peripheral wall of the male valve body 10, and a first inclined surface 12 which can act on the middle part of the locking pin 4 is arranged at one end, close to the female connector, of the annular clamping table 11.
A fixed valve core 13, a movable valve sleeve 14 and a first spring 15 are arranged in the first flow channel 1, and two ends of the first spring 15 are respectively connected with the movable valve sleeve 14 and the inner wall of the first flow channel 1; a movable valve core 16 and a second spring 17 are arranged in the second flow passage 9, and two ends of the second spring 17 are respectively connected with the movable valve core 16 and the inner wall of the second flow passage 9.
The end of the annular clamping platform 11 far away from the female joint is provided with a second inclined surface 18 which can act on the middle part of the locking pin 4.
The working principle of the quick connector locking mechanism provided by the utility model is as follows: when the connection operation of the male connector and the female connector is carried out, the male valve body 10 is inserted into the female valve body 2 by one hand, the male valve body 10 is firstly contacted with the movable valve sleeve 14 and pressed into the female valve body 2 together against the movable valve sleeve 14, so that the first spring 15 is compressed, meanwhile, the fixed valve core 13 is pressed into the male valve body 10 against the movable valve core 16, so that the second spring 17 is compressed, then along with the increase of the pressing force, the mutual pressing depth of the male end and the female end is deepened, and the annular clamping table 11 on the male valve body 19 pushes the locking pin 4 to move along the inclined groove 3 and away from the axis of the female valve body 2 through the first inclined surface 12, in the process, the locking pin 4 drives the tightening ring 7 and the unlocking ring 5 to retreat and compress the tightening spring 8, until the annular clamping table 11 moves to cross the locking pin 4, the tightening ring 7 pushes the locking pin 4 to reset under the elastic force of the tightening spring 8, so that the locking pin 4 is clamped at the rear side of the annular clamping table 11, and the locking pin 4 contacts with the second inclined surface 18 of the annular clamping table 11, at this time, the male valve body 10 cannot return, and the second flow passage 9 in the male valve body 10 is communicated with the first flow passage 1 in the female valve body 2, so that the connection operation of the male connector and the female connector is completed. When the disconnection operation of the male connector and the female connector is carried out, the unlocking ring 5 is pulled by one hand to retreat, the unlocking ring 5 drives the jacking ring 7 to retreat so as to release jacking of the locking pin 4, at the moment, the first spring 15 exerts acting force on the male valve body 10 through the movable valve sleeve 14, the annular clamping table 11 of the male valve body 10 pushes the locking pin 4 to the direction far away from the axis of the female valve body 2 through the second inclined surface 18 until the locking pin 4 moves to the edge of the second inclined surface 18, at the moment, the male valve body 10 retreats from the female valve body 2 under the elastic force action of the first spring 15, and therefore the disconnection operation of the male connector and the female connector is completed.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the technical principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
