When the connection between the input hose and the output hose needs to be quickly disconnected, only a spanner is needed to clamp the female screw sleeve 21 and the male screw sleeve 31 respectively, and then the female screw sleeve is twisted in the opposite direction, and as the bottom of the female screw 22 is in threaded fit with the male screw groove 36 on the male screw sleeve 31, the female screw sleeve 21 drives the female screw 22 to be separated from the male screw groove 36 of the male screw sleeve 31 during reverse rotation, after the male screw sleeve 31 is separated from the female screw 22, the female screw 22 and the male screw 32 are held by both hands, and the positioning bolt 9 and the limiting bolt 10 are separated from the positioning groove 11 and the limiting groove 12 respectively by pulling in the opposite directions, so that the quick connection can be quickly disassembled;
The through holes 27 on the sealing gasket 26 can be communicated with the male head channel 35 and the female head channel 24, so that fluid or gas which is introduced into the through holes 27 from the female head channel 24 cannot leak and can be completely introduced into the male head channel 35, the sealing gasket 26 is integrally customized, and the sealing gasket has the sealing deformation resistance 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, so that the sealing gasket 26 cannot be damaged when the top end of the male head 32 is abutted against the bottom end of the female head 22, namely, the fastening connection between the male head 32 and the female head 22 is completed by adopting a wrench, the strength 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, the sealing gasket 26 is 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 the sealing surface is the rest part of the top surface of the male head 32 and the bottom surface of the female head 22 outside the caulking groove 25, so that the sealing gasket 26 cannot be broken and damaged;
When the input hose or the output hose is connected with the measuring needle 5, the input hose or the output hose is directly inserted on the measuring needle 5;
When the measuring needle 5 is connected with the fixed groove 34 or the female head 22 of the male head 32, the sealing ring is sleeved in the annular groove of the hollow screw rod 6, then the hollow screw rod 6 of the measuring needle 5 is screwed into the threaded mounting inner hole formed in the fixed groove 34 or the female head 22 until one side of the connecting plate facing the hollow screw rod 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 rod 6 and the threaded mounting inner hole are screwed tightly, and the sealing ring in the annular groove on the hollow screw rod 6 is accommodated in the sealing ring groove on the threaded mounting inner hole and is tightly pressed by the connecting plate and the bottom surface of the sealing ring groove, so that the fixing of the measuring needle 5 and the sealing of the male head channel 35 or the female head channel 24 are completed;
The marking plates 7 are fixedly sleeved on the male probe assembly 33 and the female probe assembly 23, the marking plates 7 can not only mark serial numbers of the probes 5 and prevent the connection errors of the input hose and the output hose, but also limit and fix the probes 5, prevent the probes 5 from bending, and prevent dust, water drops and the like in the outside air from entering to pollute and affecting the connection stability and the data accuracy;
In addition, the marking plate 7 is fixed through the cooperation of the rivet and the rivet table, and sealing glue 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.
While the invention has been described in detail in the foregoing general description and specific examples, it will be apparent to those skilled in the art that modifications and improvements can be made thereto. Accordingly, such modifications or improvements may be made without departing from the spirit of the invention and are intended to be within the scope of the invention as claimed.
