リアランスを広げると、パイプ接合のガタを発生して使
いにくいものにしていた。Problems to be Solved by the Invention However, in the above-described conventional configuration, since the joining surface is in the entire joining mode, dust sucked by cleaning enters the joining surface and accumulates. A hardening defect occurred. In order to prevent this, if the clearance at the joint surface is widened, rattling of the pipe joint is generated, making it difficult to use.
そこで本発明は、このような従来の問題点を解消した
もので、パイプ接続部の塵埃付着による着脱操作性を良
好とし、かつパイプの剛性を高めて掃除作業性を向上さ
せることを目的とする。Accordingly, the present invention has been made to solve such a conventional problem, and has an object to improve the cleaning workability by improving the operability by attaching and detaching dust to a pipe connecting portion and increasing the rigidity of the pipe. .
課題を解決するための手段 上記目的を達成するために本発明は、第１パイプと、
この第１パイプに内嵌合される第２パイプとを具備し、
この第２パイプの第１パイプに対する接合部の外周面に
は同第１パイプの内周面に接する環状平面を長手方向に
間隔をおいて形成し、かつこれら平面間を凹状に形成
し、前記凹状部分に長手方向のリブを形成したものであ
る。Means for Solving the Problems In order to achieve the above object, the present invention provides a first pipe,
A second pipe fitted inside the first pipe,
On the outer peripheral surface of the joint portion of the second pipe to the first pipe, annular planes that are in contact with the inner peripheral surface of the first pipe are formed at intervals in the longitudinal direction, and these planes are formed in a concave shape. A rib in the longitudinal direction is formed in the concave portion.
作用 本発明のパイプ接続装置は、上記の構成により、第２
パイプを第１パイプに内嵌合して差し込んだ場合、同第
２パイプの嵌合部の両端部側は、パイプの挿入時に密状
態に第１パイプと嵌合されるが、その中間部には大きく
隙間を構成しているので離脱時には両パイプの接合面に
堆積した塵埃が当該隙間に払われ離脱しやすくなる。Action The pipe connection device of the present invention has
When the pipe is internally fitted and inserted into the first pipe, both ends of the fitting portion of the second pipe are tightly fitted with the first pipe when the pipe is inserted, Has a large gap, so that the dust accumulated on the joint surface of the two pipes at the time of detachment is blown to the gap and easily detached.
また、リブを形成することでパイプ接合でのパイプ剛
性を高め、しなりの少ない使いやすいものにする。In addition, by forming the ribs, the rigidity of the pipe at the time of joining the pipes is increased, so that the pipe is less bent and easy to use.
実 施 例 以下、本発明の実施例を添付図面にもとづいて説明す
る。Embodiments Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
第１図において、２は第１パイプに内嵌合する第２パ
イプであり、その外周面には、間隔をおいて２条の環状
平面3,4が形成してあり、またそれらの間は凹状部６が
存在する。In FIG. 1, reference numeral 2 denotes a second pipe which is fitted inside the first pipe, and two annular flat surfaces 3, 4 are formed at an outer peripheral surface thereof at intervals, and a space between them is provided. There is a concave portion 6.
上記環状平面3,4は第１パイプ１の内周面５に当接す
るように構成している。The annular flat surfaces 3 and 4 are configured to contact the inner peripheral surface 5 of the first pipe 1.
第２図の実施例では、前方の環状平面３から凹状部６
にかけて長手方向のリブ７を形成している。また第３図
は、リブ７を両環状平面3,4を結ぶように長手方向に構
成したものである。In the embodiment shown in FIG.
To form a longitudinal rib 7. FIG. 3 shows the rib 7 formed in the longitudinal direction so as to connect the two annular flat surfaces 3 and 4.
上記の構成において、掃除作業時のパイプ接合状態に
おいて環状平面3,4が接合相手の内周面５に当接してい
るのでパイプ接合のガタを無くすことができるととも
に、その間が凹部となっているので、接合部分の長さが
短く面積が小さいために、塵埃吸入によるパイプ接合部
への塵埃の堆積分がこの凹部に拡散され、パイプ離脱が
固くなるのを防止できるものである。In the above configuration, since the annular flat surfaces 3 and 4 are in contact with the inner peripheral surface 5 of the mating partner in the pipe joining state at the time of the cleaning operation, the play of the pipe joining can be eliminated, and the gap therebetween is a concave portion. Therefore, since the length of the joining portion is short and the area is small, the accumulation of dust on the joining portion of the pipe due to dust inhalation is prevented from being diffused into the concave portion, and the detachment of the pipe can be prevented from becoming hard.
また、第２図，第３図のようにリブ７を形成すること
により、掃除作業時のパイプ上側からの加重に対する剛
性を強化するものである。By forming the ribs 7 as shown in FIGS. 2 and 3, the rigidity against the load from the upper side of the pipe during the cleaning operation is enhanced.
発明の効果 以上のように本発明によれば、パイプ接合のガタツキ
を損う事なくパイプ着脱性を著しく改善できるものであ
り、また掃除作業時のパイプの剛性を高めパイプのしな
りをなくして使いやすい電気掃除機用パイプ接続装置を
提供し得るものである。Advantageous Effects of the Invention As described above, according to the present invention, it is possible to significantly improve pipe detachability without damaging the rattling of the pipe joint, and also increase the rigidity of the pipe at the time of cleaning work and eliminate the bending of the pipe. An easy-to-use vacuum cleaner pipe connection device can be provided.
