Description

The fixing struture of a multi-step foldable pipe

The present invention relates to a multi-stage pipe fastening structure, and more particularly, to a multi-stage pipe fastening structure in which a small diameter pipe is inserted into a pipe of a large diameter so that it can be fixed and released easily, The present invention relates to a multi-stage pipe fixing structure which is developed in order to provide a multi-stage pipe fixing structure.

There are two types of pipes: a folding type in which several pipes with different diameters are inserted sequentially, a folding type in which the pipes are pulled out and fixed, and a separable type in which a plurality of pipes are assembled to each other to be.

In the case of the separation type, the length of the separation type is shorter than that of the long type, so it is easier to carry and store than the long type. However, there is a characteristic that the connection can be firmly established according to the connection type.

On the other hand, in the case of folding type, not only the length but also the volume is greatly reduced, which is very easy to store and carry, but most of the drawbacks are that solid fixing is not performed.

In the case of the fixed type in the folding type, when the small diameter pipe inserted in the large diameter pipe which is seen in the old antenna and the fishing rod is pulled out and the outer diameter is gradually expanded and fixed, It is not suitable for the part where the force acts.

In addition, when a flange coupled to the end of a large diameter pipe is provided with a pair of flanges to rotate the outer flange, the process of fixing the inner flange by pressing the small diameter pipe is troublesome. There is a risk of looseness or breakage.

Also, there is a method in which a hook protruded by an inner spring is inserted and caught in a groove of a pipe of a large diameter. However, in this case, even if the pipe is slightly rotated, it is not fixed and is not inserted into a button or hook of a large- Is disadvantageous in that it is inconvenient to press the button with the button being in close contact with the bottom of the pipe of the large diameter, and loose and the flow is severe.

Therefore, it is necessary to develop a multistage pipe fastening structure that has a simple structure but has a fixed fastening and is easy to use.
