Description

High-sealing type quick pneumatic connector capable of performing secondary limiting

Technical Field

The invention relates to the technical field of quick pneumatic connectors, in particular to a high-sealing type quick pneumatic connector capable of performing secondary limiting.

Background

The quick pneumatic connector is a quick connector mainly used for air piping and pneumatic tools, when the connector which can realize pipeline connection or disconnection is not linked without tools, when a ferrule of a parent body moves to the other end, a stainless steel ball automatically rolls outwards, a daughter is disconnected under the action of the common spring force of the parent body and the daughter, valves of the daughter and the parent body are respectively closed and the fluid flow is instantly blocked, and the quick pneumatic connector is divided into 1 two-end open-close type, wherein when the parent body is linked, when the daughter is inserted into the parent body, the ferrule returns to the original position under the action of the spring, the steel ball rolls to lock the daughter in tight connection, meanwhile, the valves of the parent body and the daughter are mutually pushed to be opened, the fluid flows, and the O-shaped ring can completely block the leakage of the fluid; 2. both ends are open: unlinked-when the ferrule of the mother body is pushed to the other end, the steel balls automatically roll outwards, and therefore the daughter body is removed; the fluid flows out and is linked because the daughter and the parent body are not provided with valves, when the daughter is inserted into the parent body, the ferrule is pushed to the previous position by the acting force of the spring of the ferrule, the steel balls are locked, the fluid flows, and the O-shaped ring is arranged in the fluid flow to prevent liquid leakage; 3. one-way open-close type: when the connection is not carried out, when the ferrule of the parent body moves to the other end, the stainless steel ball automatically rolls outwards, the daughter is bounced open by the counterforce of the valve spring, the valve can be automatically closed to block the fluid flow, when the daughter is inserted into one side of the parent body with the ferrule, the valve is opened to cause the fluid flow, the gasket is pushed back to the original position by the force of the spring, the stainless steel ball can be locked to ensure the connection of the daughter and the parent body, the gasket inside can completely block the leakage of the fluid, and the connection is not required to be used for purposes other than quick fluid connectors, and the use attention points are as follows: the quick connector is not required to be used for fluids other than applicable fluids, is not required to be connected with quick fluid connectors produced by other companies, is not required to exceed the highest using pressure when in use, is not required to be used outside the using temperature range, prevents the abrasion or leakage of sealing materials, is not required to be manually beaten, bent, stretched, prevents the damage, is not required to be used in places where metal powder or sand dust is mixed, prevents the poor work or the leakage, can cause the poor work or the leakage if sundries are adhered, and is not required to be disassembled, so that the application range is as follows: the quick coupling for connecting pneumatic tools such as an air pipeline, an air compressor, a grinding machine, an air drill, a striking wrench, a pneumatic screwdriver and the like has a plurality of defects in the existing quick pneumatic coupling in the market, such as:

1. the quick pneumatic connector in the current market does not have a secondary limiting function, and because the quick pneumatic connector in the current market has defects, a mechanism which can be used for secondary limiting is lacked, so that the quick pneumatic connector is not firm in connection, the quick pneumatic connector is easy to break in the connection process, and further air leakage occurs, so that the environment pollution or potential safety hazard is caused, and the quick pneumatic connector in the current market is not practical;
