Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a slide pole used to stand a tent, a camouflage net or the like at a predetermined height.

[Conventional technology]

In order to support a tent, camouflage net, etc. upright at a predetermined height, multiple columns of tube pillars are sequentially inserted and extended so that a so-called sliding slide pole, which is long, is expandable and portable. It has been widely used due to its good properties and easy operation of expansion and contraction.

However, most conventional slide poles have plugs attached to the joints of the upper and lower pipe columns and insert and hold the plugs, but the plugs often fall off or become lost, making it impractical. Also, in cold regions, the insertion holes are often frozen and blocked, and mud is often attached during transportation, which makes it impossible to insert plugs. There is also a screw type that replaces this, but the screw part wears relatively early and the service life is short. Besides, the screw type (similar to the present invention) is also used, but it is a target When the weight of tents, camouflaged nets, etc. is large, the mooring force for supporting them is insufficient, and the emergence of a slide pole having a stable and reliable mooring force has been strongly demanded. .

[Problems to be solved by the invention]

The present invention has been made in view of such a situation, and even when a large tent or a camouflaged net which is relatively heavy when standing is supported, a slide pole having a sufficient holding force, that is, a bearing strength, can be further handled. It is an object of the present invention to provide a slide pole which has many advantages such that it is easy and the manufacturing cost is relatively low, and the height of the pole can be arbitrarily changed at any time.

[Action]

In the present invention, due to both the anti-slip effect in the large diameter column due to the elastic ring of the anti-slip collar part and the pressure contact effect within the large diameter column due to the elastic ring of the tightening collar part, the space between the large and small tubular columns is Fixation can be achieved.

First, the anti-slip effect is that the collar is sandwiched between the metal rings and tightened, and the two anti-slip collars expand and bulge outward due to the notches and adhere to the inside of the large-diameter pipe column. It is generated by force. In this case, two anti-slip collars are provided side by side to synergistically increase the anti-slip effect of the elastic ring.

On the other hand, the pressure contact effect is generated when the elastic body ring in the tightening collar portion and the circumferential groove portion of the collar portion cooperate with each other to press the elastic body ring into the inner side of the large diameter pipe column. Since the phase difference of the circumferential groove is 90 ° between the two tightening collars, a pressure welding effect can be obtained over the entire circumference of the inner wall.
