Description

Integral close-fitting press-riveting quick-inserting pneumatic connector Technical Field The utility model relates to the technical field of pneumatic connectors, in particular to an integrated tight-fitting press-riveting quick-insertion pneumatic connector. Background Among automatic devices, pneumatic, solenoid valves are often used, and are also a major device. The connection between the air pipe and the electromagnetic valve generally needs a joint to be connected, the joint is connected with the electromagnetic valve through screw threads at present, screw threads are required to be processed on the electromagnetic valve, and screw threads matched with the screw threads are also required to be processed on the joint. The processing screw thread also needs certain time and technology cost, and the solenoid valve still needs the installation with the joint after the purchase, probably still can be because the screwing of screw thread moves during the installation, and the friction running-in of two teeth leads to having the dropping of metal fillings, and the metal fillings can get into the solenoid valve, leads to the production of trouble, and tracheal screw thread is screwed up simultaneously and is unable to guarantee its gas tightness, and then leads to the problem that the joint can appear leaking gas. Most of the existing pneumatic connectors are disposable, and the clamp springs inside the pneumatic connectors cannot be replaced when damaged and can only be directly discarded, so that the waste of materials and the increase of the use cost are caused, and therefore, a novel pneumatic connector needs to be developed. Disclosure of utility model The utility model provides an integrated tight-fit press-riveting quick-insertion pneumatic connector aiming at the problems. In order to solve the problems, the utility model adopts the following technical scheme: an integral close-fitting press-riveting quick-insertion pneumatic connector, comprising: The lower end face of the valve body is provided with a connecting air channel, the top of the connecting air channel is communicated with a connecting vent hole, the bottom of the connecting air channel is in an opening shape, and a close-fit squeeze rivet joint is arranged in the connecting air channel; Further comprises: And the fastening core button is inserted into the close-fit press rivet joint. Preferably, the snap spring and the gasket are fixedly arranged in the close-fit press rivet joint, the press core button is inserted in the close-fit press rivet joint, and the press core button, the snap spring and the gasket are communicated with the inside of the sealing ring. Preferably, a clamp spring and a gasket are arranged in the close-fit squeeze rivet joint, and the button of the buckle core body, the clamp spring and the gasket are communicated with the inside of the sealing ring. Preferably, the buckle core button comprises an extrusion part and a pulling and inserting part, wherein an opening groove is formed in the extrusion part, and the opening groove extends to the pulling and inserting part. Preferably, one end of the extrusion part is provided with a limiting boss, and one side of the limiting boss is provided with a chamfering structure. Preferably, a fastening structure is arranged on the inner side of the fastening core button. Preferably, a connector cavity is arranged in the buckle core button, and a shaping boss structure is arranged on the inner side of the connector cavity. Preferably, two ends of the shaping boss structure are respectively provided with a first conical structure surface and a second conical structure surface, and two ends of the second conical structure surface are respectively provided with a first flange structure and a second flange structure. The beneficial effects of the utility model are as follows: The utility model sets up the joint and the mode of the tight fit press rivet fit connection, can connect the joint conveniently, easy to install, easy to dismantle, change of the part after the installation, can guarantee the tight tightness of the joint junction through the mode of the tight fit press rivet at the same time, and then guarantee the gas tightness of the joint junction. Meanwhile, metal scraps cannot be generated in the installation process, so that the stability and safety of the electromagnetic valve in the use process are improved, and the electromagnetic valve has practicability and use universality.
