Description

  The present invention relates to a climbing multi-stage stick, and in particular, an outer connecting pipe having a fixed gap having an engaging end formed in the lower part thereof and an engaging hole formed on the outer peripheral surface, and an outer connecting pipe An inner connecting pipe that can be adjusted in length by being inserted into the inner connecting pipe, a support body that is coupled to the upper part of the inner connecting pipe and that has a pressing gap that presses the inner peripheral surface of the outer connecting pipe, and a concave groove inside the support body The present invention relates to a button type mountain climbing cane that includes a button that locks and unlocks by being inserted into or separated from a locking hole of an outer connecting officer by being elastically provided by an elastic member that is inserted into or separated from a through hole.

  The structure of a conventional button type mountain climbing cane is shown in FIGS.

  The multistage stick according to the prior art includes an outer connecting pipe 1 disposed at an upper portion and an inner connecting pipe 11 inserted into the outer connecting pipe 1. If the connection structure of these connection pipes is seen, the fixed gap 3 in which the engagement end 4 was formed will be couple | bonded with the lower part of the outer side connection pipe 1, and the locking hole 2 will be formed in the outer peripheral surface. A support body 14 is provided on the inner upper part of the inner connection pipe 11 that is inserted into the outer connection pipe 1 and can be adjusted in length, and a pressure that presses the inner peripheral surface of the outer connection pipe 1 is provided on the upper stage of the support body 14. A gap 13 is formed. Further, in order to fix and separate the outer connecting pipe 1 and the inner connecting pipe 11, a through hole 12 is formed in the inner connecting pipe 11, and a locking hole 2 is formed in the outer connecting pipe 1. Further, a button 22 that locks and unlocks by being inserted into or separated from the locking hole 2 of the outer connecting pipe 1 through the through-hole 12 by the elastic force of the elastic member 21 provided at the lower part of the support 14. Is provided.

  In such a conventional multi-stage stick, as shown in FIG. 1, when the button 22 is pushed and the inner connecting pipe 11 is pushed upward in a state where the button 22 is inserted into the locking hole 2 of the outer connecting pipe 1, the button 22 Since the elastic member 21 is compressed and contacts the inner peripheral surface of the outer connecting pipe 1, the length of the inner connecting pipe 11 can be adjusted in the outer connecting pipe 1.

  After the inner connecting pipe 11 is moved to the required length and adjusted, the compressed button 22 is inserted into the other locking hole 2 formed in the outer connecting pipe 1, so that the adjusted length is adjusted. Can be maintained.

  However, since the above-described prior art is configured such that the cylindrical inner connecting pipe 11 is inserted into the cylindrical outer connecting pipe 1, the inner connecting pipe 11 is linearly moved while the button 22 is compressed and moved. However, it is difficult to align the next locking hole 2 and the button 22 with each other.

  Therefore, after the inner connecting pipe 11 is roughly moved, the compressed button 22 is engaged while pushing or pulling the inner connecting pipe 11 or by slightly rotating the inner connecting pipe 11 leftward or rightward. Since it must be engaged with the stop hole 2, it is very inconvenient and troublesome.

  Further, when the inner connecting pipe 11 is pulled too much below the outer connecting pipe 1 or when the tip of the inner connecting pipe 11 is locked to another object in a folded state, the inner connecting pipe 11 passes through. While the button 22 inserted into the hole 12 moves in a compressed state, it eventually passes over the engagement end 4 formed in the fixed gap 3 of the outer connecting pipe 2 and is shown in FIG. 2 as a virtual line (one-dot chain line). As shown, the problem that the inner connecting pipe 11 is completely separated from the outer connecting pipe 1 occurs.

  As described above, since the inner connecting pipe 11 is easily separated from the outer connecting pipe 1, the inner connecting pipe 11 is frequently lost, and the reliability of the stick is lowered.

  Therefore, the present invention has been made to solve such a conventional problem, and a fixed gap in which a close contact piece of a lower elastic piece provided on a support body of an inner connecting pipe is coupled to an outer connecting pipe. Engage with the engagement end to prevent movement, prevent the inner connection tube from being detached from the outer connection tube, and rotate the inner connection tube with the contact piece engaged with the engagement end of the fixed gap If this is done, the button that has been compressed can be automatically inserted into the locking hole of the outer connecting pipe and maintained in the locked state, so the button type mountain climbing cane can be easily coupled to the locking hole. The purpose is to provide a structure for preventing connection pipe detachment.

  In order to solve the above-described problems, the connection type detachment prevention structure for a button type mountain climbing cane according to the present invention has a fixed gap having an engagement end formed at a lower portion thereof, and is connected to an outer peripheral surface. An outer connecting pipe in which a stop hole is formed, an inner connecting pipe that is inserted into the outer connecting pipe and can be adjusted in length, and is joined to an upper portion of the inner connecting pipe to press the inner peripheral surface of the outer connecting pipe The support body in which the pressing gap is formed and the elastic member elastically provided in the concave groove inside the support body are inserted into or separated from the locking hole of the outer connecting pipe through the through hole and locked. And a button-type mountain climbing cane having an unlocking button, the inner connecting pipe is extended downward from the bottom surface of the support body of the inner connecting pipe in order to prevent the inner connecting pipe from being detached from the outer connecting pipe. The elastic piece and the elastic force of the elastic piece A contact piece formed at a lower stage of the elastic piece so as to be in close contact with the inner peripheral surface of the connection pipe, and a through hole formed in the inner connection pipe so that the contact piece contacts the outer connection pipe. To do.

  Here, it is preferable that the contact piece has a larger area than the engagement hole formed in the outer connection pipe so that the contact piece does not engage with the engagement hole of the outer connection pipe during the movement.

  According to the button type mountain climbing cane of the present invention configured as described above, the lower elastic piece close contact piece provided on the support body of the inner connecting pipe is engaged with the engaging end of the fixed gap coupled to the outer connecting pipe. It is possible to prevent the inner connecting pipe from being detached from the outer connecting pipe.

  Also, when the inner connecting pipe is rotated with the contact piece engaged with the engaging end of the fixed gap, the compressed button is automatically inserted into the locking hole of the outer connecting pipe to maintain the locked state. Therefore, the button can be easily coupled to the locking hole.
