Joint structure

Abstract

The invention discloses a joint structure. The joint structure comprises a first joint and a second joint which are mutually connected; a buckling block is arranged in a protruding way on the pipe wall at one end of the first joint; a groove, a spring space, a buckling disengaging part and a retainer ring part are arranged on the pipe wall of the second joint; a spring component obliquely extends and is formed in a direction towards the buckling disengaging part on the spring space; and when the first joint is connected with the second joint, the buckling block slides into the groove, and then, the joints are rotated, so that the buckling block is moved along the direction of the groove and jacks the spring component open for clamping and fixing. By means of the design, the joint structure is a practical creation which is easy to manufacture, convenient to operate and difficult to loose, and can be quickly joined.

Description

technical field [0001] The invention relates to a joint structure, in particular to a joint structure characterized in that two joints are respectively provided with snap-press parts and release parts. Background technique [0002] There are many products with inflatable airbags on the market, such as air mattresses, children's swimming pools, rubber boats, etc., and these products all need to be provided with an inflatable joint for users to inflate the airbags before using the products. [0003] In the prior art, the joint structure used to inflate the airbag is made of an elastic hollow hose made of glue. One end of the pipe body is arranged in the airbag, and the other end is connected with a plug body, and a plug body is arranged in the pipe body. The rubber check valve piece prevents gas from leaking out. However, when this kind of joint is inflated, insert the exhaust head of the pumping device into the hose and press the check valve piece against an angle to drive th...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the joint structure used to inflate the airbag is made of an elastic hollow hose made of glue. One end of the pipe body is arranged in the airbag, and the other end is connected with a plug body, and a plug body is arranged in the pipe body. The rubber check valve piece prevents gas from leaking out. However, when this kind of joint is inflated, insert the exhaust head of the pumping device into the hose and press the check valve piece against an angle to drive the gas into the airbag. After repeated use for several times, the hose is easy to loosen or break, and the joint must be fixed by hand when inflating the exhaust head and the hose, otherwise the exhaust head and the joint will become loose. It brings considerable inconvenience to users, so many joint structures have been produced on the market in response to the above-mentioned shortcomings of joints to improve

[0004] In order to solve the shortcomings of the above-mentioned joints, there is another joint structure on the market, which is composed of a male joint, a female joint and a fastening piece. One end of the male joint is provided with a clamping groove, and one end of the female joint Set a hole corresponding to the clamping groove, set a clamping block corresponding to the hole of the female joint on the fastening piece, buckle the clamping block into the hole of the female joint and clamp the clamping groove of the male joint with the clamping block It is easy to assemble and disassemble, and it is not necessary to fix the junction of the two joints by hand when inflating, but the joint structure is three-piece design, its manufacturing cost is relatively much higher, and the fastening parts are often lost in actual use. After the fastening parts are lost in this joint structure, the male joint and the female joint cannot be used normally, resulting in resources. Waste also brings a lot of inconvenience for users and manufacturers, so there are still shortcomings in the joint structure of the prior art that need to be improved
