Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
A quick-change structure of a quick-change connector of a pressure gauge adapting to various threads comprises a connector shell 1, a connector base 2 and a plurality of air inlets one 3, wherein the connector shell 1 is connected with the connector base 2, the air inlets one 3 are arranged on the connector base 2, the direction of the air inlets is vertical downward, the quick-change connector further comprises a quick-change shell 4, a quick-change base 5 and screw caps 6, a second air inlet 7 which is vertical upward is arranged on the quick-change base 5, a plurality of sealing gaskets 8 are arranged at the positions of the second air inlets 7, the second air inlets 7 are communicated with the first air inlets 3 through the sealing gaskets 8, the contact surface of the quick-change base 5 and the second air inlets 7 is horizontal, the quick-change base 5 is detachably connected with the quick-change shell 4, a cavity 9 for containing the quick-change connector is arranged in the quick-change shell 4, the connector shell 1 is connected with the screw caps 6, and the screw caps 6 are screwed with the inner walls of the quick-change shell 4; 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 further provided with a 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; a stop pin 13 for limiting the stroke of the positioning pin 10 is further arranged in the clamping groove 12.
The thread specification of the screw cap 6 is Tr60 x 4; the joint shell 1 is also provided with a lifting handle mechanism 14, and the lifting handle mechanism 14 is connected with the top of the joint shell 1; the quick-change housing 4 is further provided with a connecting piece 15 for replacement and disassembly with the verification platform.
The invention is subjected to a plurality of experiments and trials during the specific implementation, and the reason is that the two problems to be solved by the design are two, namely the quick disassembly and the guarantee of the sealing property are required; in the prior art, an air inlet of a quick connector generally has a vertical direction and a horizontal direction, the air inlet in the horizontal direction needs to adopt a radial sealing mode, a plurality of sealing rings are required to be installed on the inner wall of a quick-change shell 4, the outer diameter of a connector shell 1 is basically the same as the inner diameter of a cavity 9 of the quick-change shell 4 during design, and then the connector shell 1 is inserted into the quick-change shell 4, but the air inlet of the connector shell 1 is found to cut off the sealing rings on the inner wall of the quick-change shell 4 after multiple attempts, and the friction of the side sealing rings is not beneficial to the quick placement of the connector shell 1, so that the sealing performance cannot be ensured after long-term use, and the sealing rings cannot be deformed even if the air inlet I3 is repeatedly disassembled during installation; however, during axial sealing, a certain gap exists between the connector base 2 and the quick-change base 5, the gap generally ranges from 40 to 50 threads, and the gap cannot keep the air tightness of the sealing gasket 8 in the quick-change base 5, so the scheme design of the invention is ingenious, after the positioning pin 10 on the connector shell 1 is placed along the pin hole 11 on the nut 6, the positioning pin 10 can fall into the clamping groove 12, the clamping groove 12 of the nut 6 is horizontal, when the positioning pin 10 is positioned in the clamping groove 12 in the nut 6, the whole quick-change connector can be ensured to be in a vertical state, the gap between the quick-change base 5 and the connector base 2 is designed to be 1 mm, the Tr60 is 4 mm which is the thread specification of the nut 6, and the thread pitch is 4 mm, when the nut 6 rotates, only 1/4 turns are rotated, the gap between the quick-change base 5 and the connector base 2 can be offset, and the axial compression between the two is realized; make quick-operation joint's bottom and quick-change base 5's bottom closely cooperate, thereby guarantee that sealed pad 8 is compressed tightly, air inlet one 3 and two 7 intercommunications of air inlet, when needs change quick-operation joint, can directly rotate nut 6 once more, drive quick-operation joint through nut 6 and come up gradually, and make the locating pin 10 on the joint shell 1 get back to the pinhole 11 position on the nut 6 once more, stop the position that round pin 13 can effectual control locating pin 10, when making light commentaries on classics nut 6, locating pin 10 sends "the sound of" Da "and makes a sound gently, just reach the change position, carry through operating personnel and pull handle mechanism 14 this moment, just can carry whole joint shell 1, when putting into the quick-operation joint of other models once more, only need carry the handle mechanism 14 of the quick-operation joint of other models, put into the pinhole 11 of nut 6 with the locating pin 10 of joint shell 1, then light commentaries on classics nut 6 just can realize the change of quick-operation joint.
The design of the invention has two advantages, firstly, the quick-change shell 4 can be assembled with the pressure gauge calibration stand through the connecting piece 15, the existing pressure gauge calibration stand can be provided with the quick-change mechanism of the invention through the connecting piece, and the existing calibration equipment can be directly modified and upgraded; and secondly, the screw cap, 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 kept even if the product is used for a long time.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
