Fastening outer ring and inflatable goal with the fastening outer ring

Abstract

The invention discloses a fastening outer ring, which includes an outer ring and a fastening adjustment device. The outer ring has two ends and is in a retractable structure. The two ends of the outer ring form connecting ends. The fastening An adjustment device is connected to the connecting end, the fastening adjustment device adjusts the circumference of the outer ring, and it also includes a metal ring in a retractable structure, the inner wall of the outer ring is circular and has a positioning groove , the eyelet is stuck in the positioning groove and protrudes from the positioning groove. The fastening outer ring uses the linear principle of the metal ring to fasten the solid object, and then uses the outer ring to squeeze the solid object in a large area, and has a double fastening effect on the solid object, so the fastening is strong, The fastening outer ring has good sealing performance, low production cost, and can be adjusted according to the thickness, softness and hardness of the hose and the surface condition of the solid object. In addition, the invention also discloses an inflatable goal with the fastening outer ring.

Description

technical field [0001] The invention relates to a fastening outer ring, in particular to a seamless fastening outer ring used for fixing and sealing hoses in hose connections. Background technique [0002] In modern society, hoses have become an indispensable part of people’s lives. The hoses need to be connected when they are used. The connection of hoses generally requires three parts, namely hoses, hose connectors and fastening outer rings. Under the premise that the pipe and hose connectors have been fixed, the fastening outer ring further fixes the hose, and the fastening outer ring plays an important role in the connection and fastening of the hose. On the one hand, the fastening outer ring should be easy to operate and easy to use , The purpose of low cost; On the other hand, it requires good fastening and sealing. With the improvement of people's living standards and the enrichment of entertainment life, hoses are also applied to people's entertainment life, such as...

Problems solved by technology

The tongue throat hoop overlaps up and down through a metal tongue. By tightening the tongue, the inner diameter of the tongue is gradually reduced to lock the object to be fixed. Since the metal tongue is a plane, it is only suitable for locking the plane, but The tongue has a certain thickness, and there is a drop of tongue thickness between the upper circle of tongue and the next circle of tongue, forming a 90° right-angle space. If the hose is relatively thin or hard, the right-angle space often forms Dead angle, resulting in air leakage, which makes the sealing of the tongue throat hoop not good. At the same time, the product is mostly locked by a screw device, and the screw device is fixed on the tongue by another iron piece. The iron piece of the fixed screw device There will also be a dead angle of air leakage between the tongue and the tongue; moreover, when this tongue throat hoop meets a hose connector with external teeth or grooves, the fastening effect is not good; another common tongue throat hoop The locking mode is to open a row of threaded openings on the tongue, and then move the screw on these threaded openings to gradually lock the object to be fixed. This method requires high technology. If the screw and the threaded opening do not cooperate well, it will run If the metal tongue throat hoop is made of iron material, the iron sheet is prone to edges or burrs, which is more likely to cause damage to the hose, and the iron throat hoop The tongue is soft and easy to deform; if it is made of stainless steel, it is more elastic and not easy to deform, but the price is more expensive and the production cost is high

The steel wire hose clamp bends two steel wires into a circle, and tightens the circle to lock the object to be fixed. The steel wire hose clamp has a strong force and a small contact area with the hose, which can bite the hose tightly, but in case of When the hose is thinner, the hose will be broken. At the same time, the rigidity of the steel wire should be better, and the steel wire should not be too thin, otherwise it will easily deform and cause air leakage. The pipe clip is fixed and cannot be adjusted. single solid
