All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The utility model provides a quick change structure of manometer quick-operation joint that adapts to multiple screw thread, includes joint shell 1, connects base 2 and air inlet one 3 a plurality of, joint shell 1 is connected with joint base 2, and air inlet one 3 is established on joint base 2 and the direction is vertical decurrent, still includes quick change casing 4, quick change base 5 and nut 6, be equipped with vertical ascending air inlet two 7 on the quick change base 5, air inlet two 7 department is equipped with a plurality of sealed pads 8, air inlet two 7 are through sealed 8 and air inlet one 3 intercommunication, the face that quick change base 5 contacted with air inlet two 7 is horizontal, be equipped with the cavity 9 that is used for holding quick-operation joint in the quick change casing 4 between the quick change casing 5, joint shell 1 is connected with nut 6, the spiro union between the inner wall of nut 6 and quick change casing 4; the connector comprises a connector shell 1, a nut 6 and a clamping groove 12, wherein the connector shell 1 is provided with a positioning pin 10, the nut 6 is provided with a pin hole 11 for the positioning pin 10 to pass through, the nut 6 is also provided with the clamping groove 12 for accommodating the positioning pin 10, the pin hole 11 is communicated with the clamping groove 12, and the clamping groove 12 is horizontal; the clamping groove 12 is also provided with a stop pin 13 for limiting the travel of the positioning pin 10.

The application has been subjected to many experiments and attempts in the concrete implementation, because the design needs to solve two problems, namely quick disassembly and sealing performance; in the prior art, the air inlet of the quick connector is generally in a vertical direction and a horizontal direction, the air inlet in the horizontal direction needs to be in a radial sealing mode, a plurality of sealing rings are required to be installed on the inner wall of the quick-change shell 4, the outer diameter of the connector shell 1 is basically the same as the inner diameter of the cavity 9 of the quick-change shell 4 during design, the connector shell 1 is then inserted into the quick-change shell 4, but a plurality of attempts find that the air inlet of the connector shell 1 cuts off the sealing rings on the inner wall of the quick-change shell 4, the friction of the side sealing rings is not favorable for quick-putting the connector shell 1, so that the tightness cannot be ensured after long-term use, and the sealing rings are not deformed when the air inlet I3 is disassembled back and forth for a plurality of times during installation; however, when the joint is axially sealed, a certain gap exists between the joint base 2 and the quick-change base 5, the size of the gap is generally about 40-50 threads, the gap cannot keep the air tightness of the sealing gasket 8 on the quick-change base 5, so the scheme design of the application is very ingenious, after the locating pin 10 on the joint shell 1 is put into the clamping groove 12 along the pin hole 11 on the nut 6, the locating pin 10 falls into the clamping groove 12, the clamping groove 12 of the nut 6 is horizontal, when the locating pin 10 is positioned in the clamping groove 12 in the nut 6, the whole quick-change joint can be ensured to be in a vertical state, the gap between the quick-change base 5 and the joint base 2 is designed to be 1 millimeter, tr60 x 4 is the screw specification of the nut 6, the screw pitch is 4 millimeters, and when the nut 6 rotates from the figure, the gap between the quick-change base 5 and the joint base 2 can be offset by only 1/4 circles, and the axial compression between the two can be realized; the bottom of the quick connector is tightly matched with the bottom of the quick-change base 5, so that the sealing gasket 8 is tightly pressed, the first air inlet 3 and the second air inlet 7 are communicated, when the quick connector needs to be replaced, the screw cap 6 can be directly rotated again, the quick connector is driven to gradually float upwards through the screw cap 6, the positioning pin 10 on the connector housing 1 is returned to the position of the pin hole 11 on the screw cap 6 again, the positioning pin 13 can effectively control the position of the positioning pin 10, when the screw cap 6 is rotated slightly, the positioning pin 10 emits a sound of 'pyridazine', the replacement position is reached, at this time, the whole connector housing 1 can be lifted up by lifting the handle mechanism 14 by an operator, and when the quick connector of other types is put in again, the handle mechanism 14 of the quick connector of other types is only needed to be put in the pin hole 11 of the screw cap 6, and then the quick connector can be replaced by rotating the screw cap 6 slightly.
The design of the application has two advantages, namely, the quick-change shell 4 can be assembled with the pressure gauge verification table through the connecting piece 15, the existing pressure gauge verification table can be used for directly modifying and upgrading the existing verification equipment through the connecting piece; and secondly, the nut, the quick-change shell 4 and the quick-change base 5 of the product do not need to be disassembled, so that the air tightness and the stability of the equipment can be maintained even if the product is used for a long time.
