The implementation scenario is specifically as follows: the preset female head 22 is connected with an input hose;

the male head 32 is connected with an output hose;

the measuring pins 5 are sequenced on the indication board 7 of the female measuring pin assembly 23 from 1, for example, the number 1 female measuring pin 5 and the number 2 female measuring pin 5;

the measuring pins 5 are sequenced on the indication plate 7 of the male measuring pin assembly 33 from 1, for example, the 1 # male measuring pin 5 and the 2 # male measuring pin 5:

when multi-channel conveying is needed, firstly screwing off the male head-tail protection 4 and the female head-tail protection 1, penetrating the external input hose through the female head-tail protection 1 according to a set rule and inserting the external input hose on the measuring pin 5 of the female head measuring pin assembly 23, after the input hose is completely inserted, screwing the female head-tail protection 1 and the female head thread groove 28 in the female head screw sleeve 21, sleeving the male head screw sleeve 31 on the bottom end of the male head 32 and moving upwards along the male head 32 until the circular bottom end surface of the male head 32 is abutted against the bottom surface of the male head groove of the male head screw sleeve 31, penetrating the external output hose through the male head-tail protection 4 according to the set rule and inserting the external output hose on the measuring pin 5 of the male head measuring pin assembly 33, after the output hose is completely inserted, screwing the male head-tail protection 4 on the bottom end of the male head 32 (the bottom end of a round rod) and screwing, at the moment, because the male head-tail protection 4 is abutted against the male head-tail protection 31, the bottom end of the male head screw sleeve 31 can not be detached from the male head 32, the positioning bolt 9 is aligned with the positioning groove 11, the limiting bolt 10 is aligned with the limiting groove 12, so that the positioning bolt 9 is connected with the positioning groove 11, and the limiting bolt 10 is connected with the limiting groove 12, because the diameters of the positioning bolt 9 and the limiting bolt 10 are inconsistent, the male channel 35 is correspondingly communicated with the female channel 24 one by one according to a set rule, so that the measuring pins 5 on the female measuring pin assembly 23 are correspondingly communicated with the measuring pins 5 on the male measuring pin assembly 33 one by one, namely, the No. 1 male measuring pin 5 is communicated with the No. 1 female measuring pin 5 through the matching of the male channel 35 and the female channel 24, and thus, the multichannel communication can be realized, and the disorder of the multichannel can also be avoided, namely, the No. 1 input hose is inevitably communicated with the No. 1 output hose;

when the input hose and the output hose need to be connected through the quick connector, only the male thread groove 36 on the male thread insert 31 needs to be connected with the female thread 22 continuously, and because the male thread groove is formed in the male thread insert 31 and is in relative sliding connection with the circular table of the male thread 32, when the male thread groove 36 on the male thread insert 31 is in threaded connection with the female thread 22, the rotation of the male thread insert 31 cannot affect the male thread 32, namely the rotation of the male thread insert 31 cannot drive the male thread 32 to rotate;

when the connection between the input hose and the output hose needs to be quickly disconnected, only a wrench needs to be adopted to clamp the female screw sleeve 21 and the male screw sleeve 31 respectively, and then the female screw sleeve 21 and the male screw sleeve 31 are twisted in opposite directions, because the bottom of the female screw sleeve 22 is in threaded fit with the male screw thread groove 36 on the male screw sleeve 31, the female screw sleeve 21 can drive the female screw sleeve 22 to be separated from the male screw thread groove 36 of the male screw sleeve 31 during reverse rotation, after the male screw sleeve 31 and the female screw sleeve 22 are separated, the female screw sleeve 22 and the male screw 32 are held by two hands, and the positioning bolt 9 and the limiting bolt 10 can be separated from the positioning groove 11 and the limiting groove 12 respectively by pulling in opposite directions, so that the quick disassembly of the quick connector can be realized;

due to the arrangement of the sealing gasket 26, the through hole 27 on the sealing gasket can be communicated with the male channel 35 and the female channel 24, so that fluid or gas introduced into the through hole 27 from the female channel 24 cannot leak and can be completely introduced into the male channel 35, the sealing gasket 26 is integrally customized, and has the sealing deformation-resistant function of an O-shaped sealing ring and the end face sealing function of a flat gasket;

the thickness of the sealing gasket 26 is slightly larger than the depth of the caulking groove 25, and thus, when the top end of the male head 32 is abutted against the bottom end of the female head 22, the sealing gasket 26 cannot be damaged, namely, because the fastening connection between the male head 32 and the female head 22 is completed by a wrench, the force control effect of the wrench is poor, if the caulking groove 25 is not arranged, the sealing gasket 26 is directly arranged between the top surface of the male head 32 and the bottom surface of the female head 22, and the sealing surface is the sealing gasket 26, the sealing gasket 26 can be broken and damaged due to excessive pressure in the fastening process, after the caulking groove 25 is arranged, part of the sealing gasket 26 outside the caulking groove 25 can be pressed into the caulking groove 25, and at the moment, the sealing surface is the residual part of the top surface of the male head 32 and the bottom surface of the female head 22 outside the caulking groove 25, and the sealing gasket 26 cannot be broken and damaged;

when the input hose or the output hose is connected with the measuring probe 5, the input hose or the output hose is directly inserted on the measuring probe 5;

when the measuring pin 5 is connected with the fixed groove 34 or the female head 22 of the male head 32, firstly, the sealing ring is sleeved in the annular groove of the hollow screw 6, then the hollow screw 6 of the measuring pin 5 is screwed into the thread installation inner hole formed in the fixed groove 34 or the female head 22 until one side of the connecting plate facing the hollow screw 6 is abutted against the inner bottom surface of the fixed groove 34 or the top surface of the female head 22, at the moment, the hollow screw 6 and the thread installation inner hole are screwed, and the sealing ring in the annular groove of the hollow screw 6 is accommodated in the sealing ring groove on the thread installation inner hole and is tightly pressed by the connecting plate and the groove bottom surface of the sealing ring groove, so that the measuring pin 5 is fixed and the male head channel 35 or the female head channel 24 is sealed;

in addition, the male probe assembly 33 and the female probe assembly 23 are fixedly sleeved with the marking plates 7, the marking plates 7 can mark the serial numbers of the probes 5, prevent the input hose and the output hose from being connected in a wrong way, limit and fix the probes 5, prevent the probes 5 from being bent, and prevent dust, water drops and the like in the outside air from entering to cause pollution and influence the connection stability and the data accuracy of the probes;

in addition, the marking plate 7 is fixed through the matching of the rivet and the rivet table, and sealant is poured between the marking plate 7 and the top surface of the female head 22 and between the marking plate 7 and the inner bottom surface of the fixing groove 34 of the male head 32, so that the sealing effect can be further improved.

Although the utility model has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the utility model.
