Background
In the production operation field of enterprises, some devices using gas or liquid working media are frequently used, a hose joint is an important part for connecting a hydraulic device and a rubber hose, a medium conveying pipeline adopts a hose, and the connection and use of various high-pressure hoses and low-pressure hoses are a common phenomenon, particularly in a heat processing unit using oxygen, fuel gas, compressed air, nitrogen, hydrogen, argon, carbon dioxide gas and the like as working media. The common characteristics of the three connection modes are that the bundled or hooped hose is subjected to inward shrinkage type extrusion deformation, and the sealing and connection are realized by the anti-slip friction resistance between the inner surface of the hose or the inner surface of an inner layer pipe and the outer surface of a connecting pipe core (an inverted conical pipe joint or a smooth straight pipe joint with a large diameter and a small diameter), the connection force is only generated on the inner surface of the pipe, the connection strength and the sealing performance of the hose are not easy to guarantee without using special tools or tools, the hose is easy to leak or even fall, and the loading and unloading operations are complicated and laborious.
Disclosure of Invention
The present invention is directed to solving the above-mentioned deficiencies of the prior art and to providing an adjustable diameter end fitting for a hose.
The utility model provides an adjustable diameter's tip joint for hose, includes metal collapsible tube and screw, metal collapsible tube's both ends all be equipped with fixed joint, fixed joint all link to each other with flexible joint, flexible joint's shape be trapezoidal hundred pleat forms, be equipped with round joint recess on fixed joint's the outer wall, be equipped with the fixed disk in the joint recess, be equipped with a plurality of screw hole on the fixed disk, the screw run through the screw hole, the afterbody of screw all is equipped with the fixed head, the top of fixed head all is equipped with staple bolt body recess, flexible joint's the outside be equipped with the locking staple bolt, locking staple bolt and staple bolt body recess looks joint.
As a further improvement, the number of the screws is 4.
As a further improvement, the depth of the joint groove is equal to one fourth of the width of the fixed disc.
As a further improvement, the number of the fixing heads is 4, and the shape of the 4 fixing heads is a quarter circular ring.
As a further improvement, the diameter of the anchor ear groove is equal to that of the locking anchor ear.
As a further improvement, the fixed disc is in a circular ring shape.
Has the advantages that:
this device is provided with flexible joint, and flexible joint's shape is trapezoidal hundred pleat forms, and flexible joint cooperatees with the locking staple bolt, can adjust the diameter size of locking staple bolt at any time to the size of control flexible joint diameter, thereby enlarge metal collapsible tube's use extensively, regard as the part of connecting other rigid pipes with flexible joint, screw up the bolt behind the flexible joint with rigid pipe stopper income, alright realize connecting, simple structure, stability is better, and life increases.
