Description

Insertion and extraction structure of endoscope connector Technical Field The invention relates to the technical field of medical equipment, in particular to an endoscope connector plug structure. Background The gastroscope is widely used in the medical field, and is configured to have an elongated access portion, one end of the gastroscope is inserted into a human body, the other end is divided into a light guide portion, an air supply pipeline and an image signal harness, the light guide portion, the air supply pipeline and the image signal harness are connected with a host, the image signal harness transmits an image signal to an image processing device of the host, and the image processing device processes image information and outputs a processing result to a display. When the operator finishes the operation of the electronic endoscope or replaces the electronic endoscope, the light guide, the air supply line, and the image signal harness need to be removed. For convenience of operation, the light guide part, the air supply pipeline and the image signal wire harness are integrated into one component for insertion and extraction, and the component is called a light guide connector in the present case. Most of the pulling and inserting mechanisms of connectors used on endoscopes in the existing market utilize fastening-position hard pulling and inserting mechanisms, the hard pulling and inserting of the structure is laborious, and the inserting core is easy to damage due to violent pulling and inserting. Disclosure of Invention In order to solve the above problems, an object of the present invention is to provide an insertion structure of an endoscope connector, in which a female connector and a male connector are inserted and pulled out by means of rotational connection, and the insertion is more rapid and labor-saving when the female connector and the male connector are screwed in and out, thereby effectively protecting the insertion core. In order to achieve the purpose, the invention adopts the following technical scheme that the endoscope image processor panel comprises a connector male joint embedded in an endoscope image processor panel hole and a connector female joint butted with the connector male joint, and is characterized in that: The male connector comprises a first connecting cylinder extending out of the end part of the endoscope image processor and a male connector fixed in the first connecting cylinder, wherein the outer end of the male connector is provided with an inserting core; The connector female joint comprises a rotary shell, a first sleeve clamped in the rotary shell, an inner barrel connected to the bottom end of the first sleeve and partially extending into the first sleeve, and a second sleeve assembly arranged in the first sleeve and fixedly connected with the inner barrel, wherein the outer end of the second sleeve assembly is inserted with a female seat, and the outer end of the female seat is provided with a jack matched with the ferrule; At least two arc grooves are formed from the outer end of the first sleeve to the side wall, the arc openings of the arc grooves correspond to the first screws, and notches are formed at the inner ends of the arc grooves; The lock pin is in butt joint with the jack, the outside of the first connecting cylinder stretches into the space, the first screw is clamped into the arc opening, the rotating shell is rotated and drives the first sleeve to rotate, and the first screw moves into the clamping notch along the arc groove so that the male connector and the female connector of the connector are kept relatively locked. According to the technical scheme, after the inserting core of the male connector is in butt joint with the inserting hole of the female connector, the female seat, the second sleeve assembly and the inner barrel in the female connector are fixed relative to the male connector, the rotary shell in the female connector is fixed relative to the first sleeve, the rotary shell is rotated relative to the male connector, the first screw on the first connecting barrel in the male connector moves to the notch at the bottom of the groove along the arc-shaped groove on the first sleeve to be clamped, so that the rotary shell and the first sleeve are locked relative to the male connector, and when the male connector is unscrewed, the first screw moves to be disconnected from the first sleeve along the arc-shaped groove, and the inserting core is disconnected from the inserting hole by slightly exerting force outwards due to the fact that the inner barrel is connected with the first sleeve, so that the male connector is completely pulled out, and the male connector is more convenient and quick. Preferably, the second sleeve assembly comprises a first rotary joint and a second sleeve, the upper end head of the second sleeve extends into the first rotary joint to be sleeved and fixed, the lower portion of the female seat axially extends t
