Description

One-handed insertion of a secure quick connector structure

This creation is about a one-handed safety quick joint structure, especially one that can be opened with one hand, can open or close the connecting pipe quickly, and is safe, airtight, durable, and not easy to fall off due to collision. Insert a secure quick connector structure.

In recent years, in the field of industrial technology of existing pipe connection methods, two types of fixed and detachable connection methods have been widely used; the fixed connection method is generally through welding, hot melting, or bonding. Because it cannot be disassembled after connection, it has been adopted by a small number of people today; however, the detachable connection method is generally detachable by means of threading, snapping, or socketing, which is currently sold in the market. The joint structure is different, and usually has the disadvantages that the structure is too complicated, the processing is difficult, the disassembly and installation is not easy, and the parts are easily damaged.

For example, when using a commercially available quick connector, the operator needs to use two-hand operation when connecting or disassembling, which causes problems such as difficulty in disassembly and installation, and is generally designed in a commercially available quick-connect structure that can be engaged with one-handed operation. The utility model has a structure in which a male connector and a female connector are buckled, and the structure uses the protrusions inside the outer ring and the abutting members of the abutting component to push a plurality of balls to each other, thereby achieving the purpose of one-hand operation. However, since the commercially available one-handed safety quick joint structure does not have safety measures, the outer ring can push a plurality of spheres when the pipe joint is inserted into the body by the male joint, and then the male joint is buckled. The combination can only be achieved by the action of the connection, and can not be further locked, resulting in problems such as inaccurate bonding or pipe falling off, and causing fluid leakage in the pipe.

Moreover, in order to increase the airtight stability in the pipeline, a return spring is usually provided in the quick joint structure, and the airtight effect is achieved by the process of the return spring abutting the joint body. For example, a commercially available quick joint structure, in addition to a return spring, is additionally provided with a valve core assembly, and the valve is pressed against the return spring to achieve an airtight effect. In other words, although the use of a spring to abut the valve can partially achieve the effect of airtightness, and even further use of an O-type valve, a better degree of airtightness can be achieved, but the conditions of airtightness, stability, pressure, etc. are still extremely high when the pipe is combined. Insufficient, so still can not get good connection quality.

On the other hand, for the structural selection of the quick connector, it is necessary to consider the simplification of the structure, and select a quick connector that is easier to assemble and combine components or components to exhibit the best effect. That is, in the case of a commercially available quick connector, it is common practice to configure a specific cut shape in one of the joints, and another corresponding joint to configure a specific accommodation space, if the specific cut shape is undetermined combination , will cause the stability of the joint structure; and if the misalignment during cutting, will cause the component and the corresponding component pairing problem, resulting in waste of resources and cost. Therefore, the selection of components or components that are easier to assemble and combine in the structural selection of the quick connector is undoubtedly an important key to determining the stability and cost of use.

However, it is indisputable that at least the quick connectors sold on the market exist, for example, (1) cannot be removed by one hand; (2) it is not easy to remove and disassemble; (3) it is easy to fall off; (4) the airtight stability is poor; 5) The structure is too complicated, the assembly or assembly cost is high; (6) the parts are prone to damage problems and many other shortcomings.

Therefore, the mechanical industry does not expect to develop a kind of common defect that can improve the above-mentioned various commercial quick joints, and can further develop a one-hand operation, and can improve the airtight stability, safety, and durability. And novel techniques such as structural simplification.

In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years, reviewing and researching the problems of the conventional quick joints mentioned above, and carefully evaluating various types of one-handed operations that can be improved and improved. The improvement of airtight stability, safety, structural simplification, etc., to complete the creation.

In other words, this creation provides a one-handed insertion of a secure quick connector structure. According to the novel technology of the present invention, in addition to improving the common defects of the above-mentioned various commercially available quick connectors, it is also possible to reduce material waste caused by an excessively complicated structure, and to effectively improve the manufacturing and assembly speed and the like. In addition, the one-handed operation of the creation of the creation of the safety quick connector achieves an optimized user experience, and further improves the efficiency of the work.
