본 고안은 진공 청소기에 있어서, 선단의 먼지 흡입 노즐부와 흡입연장 호스 사이에 길이 가변식으로 결합설치되면서 손잡이 역할도 겸하는 흡입연장관에 관한 것으로, 특히 버튼식0으로 연장관의 길이를 사용자의 키나 장소에 알맞게 자유로이 가변 조절할 수 있도록한 것이다.The present invention relates to a suction extension tube having a variable length coupled between the dust suction nozzle portion of the vacuum cleaner and the suction extension hose in the vacuum cleaner, and also serves as a handle, in particular the length of the extension tube by the button type 0 user's height or location It can be freely adjusted to suit.

일반적인 진공청소기 구조를 살펴보면, 도면 제1도에서와 같이 후방부에 전동송풍 모터를 내장하고 전방부의 집진실에 흡입 연장호스 결합공(11')을 구비한 본체(1)에 플렉시블한 흡입연장호스(2')와 길이가변형 흡입연장 호스(3'), 그리고 흡입노즐(4')이 차례로 결합 설치되므로서, 전동 송풍모터의 배압에 의하여 관내에 흡입력이 작용하여 먼지가 흡입노즐-흡입연장관-흡입연장호스를 통해 집진실에 수거되는 것이다.Referring to the structure of a general vacuum cleaner, as shown in FIG. 1, a flexible suction extension hose is installed in a main body 1 having an electric blower motor in a rear part and a suction extension hose coupling hole 11 'in a dust collecting chamber in a front part. (2 '), variable-length suction extension hose (3'), and suction nozzle (4 ') are installed in turn, so that the suction force acts on the tube by the back pressure of the electric blower motor, and dust is sucked in. It is collected in the dust collection room through the suction extension hose.

여기에서, 종래의 흡입연장호스는 후방에 축소직경부(31')와 전방에 확대직경부(32')를 구비한 복수개의 연장관(3')이 상호 축소 및 확대부 결합 형태로 끼워 맞춤 결합 구성되어 있다.Here, the conventional suction extension hose is fitted with a plurality of extension pipes 3 'having a reduced diameter portion 31' at the rear and an enlarged diameter portion 32 'at the front to form a mutually reduced and expanded portion coupling form. Consists of.

따라서, 사용자가 통상적으로 흡입연장호스(2')의 곡관부(21')를 손잡이로 하여 바닥면에 흡입노즐(4')을 이동시키면서 청소작업을 행하게 될때, 사용자의 신장이나 사용 장소의 특성에 따라 흡입연장관의 길이를 가변시켜야 함에도, 종래의 끼워맞춤 결합구조에서는 연장관의 가감외에 별 다른 길이 가변 방법이 없으므로, 실제로 길이조절이 불가능하여 가변시킴이 없이 그대로 사용하므로서, 작업상의 비능률과 불편 그리고 효율적인 청소가 되지 못하는 문제점이 있었다.Therefore, when the user performs cleaning while moving the suction nozzle 4 'on the floor by using the curved pipe portion 21' of the suction extension hose 2 'as a handle, the characteristics of the user's height and the place of use Although the length of the suction extension pipe should be varied according to the above, in the conventional fitting coupling structure, since there is no variable length method other than the addition and the extension of the extension pipe, it is not possible to actually adjust the length, so it is used as it is without changing the inefficiency and inconvenience in operation. And there was a problem that can not be efficient cleaning.

따라서, 본 고안의 목적은 상기와 같은 종래의 문제점을 해결함과 동시, 길이 가변 조작형 흡입 연장관을 제공하여 사용자의 신체조건이나 작업장소별 특성에 따라 임의로 신장 또는 단축시켜 작업능률 향상과 청소의 효율을 향상시킬 수 있는 흡입연장관을 제공함에 있는 것이다.Accordingly, an object of the present invention is to solve the conventional problems as described above, at the same time, by providing a variable length operation suction extension tube to arbitrarily stretch or shorten according to the user's physical condition or the characteristics of each work place to improve work efficiency and cleaning It is to provide a suction tube that can improve the efficiency.

상기와 같은 목적을 달성하기 위하여, 내외측으로 상호 끼워 맞춤 결합되는 1쌍의 연장관을 구비하면서 외측연장관의 말단부에는 록크공과 체결 나사부를 형성하고, 록크공에는 푸쉬돌기와 록크돌기를 구비한 탄성 홀더수단이 결합 설치되면서 커버로서 커버링 되었으며, 또 다른 내측 연장관에는 길이방향을 따라 복수개의 록크공과, 외주면에 상기 외측연장관의 체결 나사부와 나사 결합될 커플링 너트가 결합되므로서, 커플링 너트를 풀면서 외측 연장관측 탄성홀더 수단의 푸쉬돌기를 누르면 록크돌기가 록크공에서 이탈되면서 내측 연장관의 록킹이 해제되어 다른 록크공을 결합시키는 방법으로 그 길이를 가변시킬 수 있도록 한 것으로, 이를 첨부된 도면에 의거 보다 상세히 설명하면 다음과 같다.In order to achieve the above object, it is provided with a pair of extension pipes to be fitted to each other in and out, while forming a lock ball and a fastening screw portion at the distal end of the outer extension pipe, the lock hole is provided with an elastic holder means having a push protrusion and a lock protrusion Covered as a cover while being installed in combination, another inner extension pipe is coupled to the plurality of lock holes along the longitudinal direction, and the coupling nut to be screwed with the fastening screw portion of the outer extension pipe on the outer peripheral surface, so as to loosen the coupling nut to extend the outer Pressing the push projection of the observing elastic holder means releases the locking protrusion from the lock hole and releases the locking of the inner extension tube so that the length can be changed by combining the other lock balls. The explanation is as follows.

즉, 도면 제2,3도는 본 고안의 구성을 나타낸 분리 사시도 및 결합상태 단면도로서, 상호 내, 외측에서 끼워맞춤 결합되는 1쌍의 내, 외측 연장관(5)(8)을 구비하면서, 보다 큰 직경의 외측 연장관(5)에는 일측단 부위외주면에 체결나사부(51)와 가이드턱(52)및 그 전방 양측에 각각 록크공(53)이 대칭으로 형성되었다.That is, FIGS. 2 and 3 are separated perspective views showing the structure of the present invention and a cross-sectional view of the coupling state, and having a pair of inner and outer extension pipes 5 and 8 that are fitted in and out of each other. In the outer extension pipe 5 having a diameter, lock balls 53 are formed symmetrically on the fastening screw portion 51 and the guide jaw 52 and both front sides of one side portion outer peripheral surface thereof.

그리고, 상기 양측록크공(53)에는 중앙부 상측에 푸쉬돌기(71)를 구비한 원호형 탄성홀더수단(7)의 내측면 양측에 형성된 록크돌기(72)가 관통 삽입 형태로 결합 되었으며, 그 외측방에는 확대 직경부(61)에 형성될 돌출공(62)으로 푸쉬돌기(71)를 돌출시킨 커버(6)가 실링패킹(64)을 접착한 실링턱(63)으로 외측면과 가이드턱(52)상에 밀폐 지지 결합 설치되었다.In addition, the lock protrusions 72 formed on both sides of the inner side surface of the arc-shaped elastic holder means 7 having the push protrusions 71 on the upper side of the center portion are coupled to each other in the lock hole 53. In the room, the cover 6 which protrudes the push protrusion 71 to the protruding hole 62 to be formed in the enlarged diameter portion 61 is a sealing jaw 63 to which the sealing packing 64 is adhered, and the outer surface and the guide jaw ( 52, an airtight support coupling was installed.

그리고, 상기 내측 연장관(8)에는 길이방향 양측으로 외측 연장관의 록크공(53)과 일치되어 상기 탄성홀더수단의 록크돌기와 삽입 결합될 복수개의 록크공(81)들이 일정 간격으로 배열 형성되었으며, 그 외주면에는 상기 체결나사부(51)와 나사 결합되는 나사부(91)를 구비한 커플링 너트(9)가 끼워 맞춤 결합되므로서, 커플링너트(9)는 체결나사부(51)와 결합되고, 내측 연장관(8)은 외측 연장관(5)내에서 양측 록크공(81)에 탄성홀더수단(7)의 록킹돌기(72)를 삽입시킨 상태로 결합 설치 구성된 것이다(도면 제3도 참조).In addition, the inner extension pipe 8 has a plurality of lock balls 81 to be inserted and coupled to the lock protrusion of the elastic holder means to be aligned at regular intervals to coincide with the lock holes 53 of the outer extension pipe in both longitudinal directions. The coupling nut 9 is coupled to the fastening screw portion 51 by the coupling nut 9 having the screw portion 91 screwed to the fastening screw portion 51 on the outer circumferential surface thereof. (8) is configured to be coupled and installed in the state in which the locking projection 72 of the elastic holder means 7 is inserted into both lock holes 81 in the outer extension pipe 5 (see Fig. 3).

이상과 같이 구성된 본 고안은, 외측연장관(5)의 커버(6)확대부 돌출공(62)으로 돌출된 푸쉬돌기(71)를 누르면 탄성홀더수단(7)의 양측단 부위가 외측으로 벌려지면서 록크돌기(72)가 록크공(81)에서 측방 이탈되므로서, 내측 연장관(8)의 록킹이 해제되므로 이를 밀어넣거나 길게 빼낸뒤, 해당 록크공을 외측 연장관측 록크공과 일치시키고 푸쉬돌기(71)에 가하던 힘을 제거하면 자체 탄성에 의해 오무라들면서 록크돌기(72)가 록크공 (81)내로 삽입되어 상호 견고하게 결합되는 것이다.The present invention configured as described above, while pressing the push projection 71 protruding into the cover 6, the enlarged protrusion hole 62 of the outer extension pipe 5, while both side end portions of the elastic holder means 7 is opened to the outside Since the locking protrusion 72 is released laterally from the lock ball 81, the locking of the inner extension pipe 8 is released so that the lock protrusion 72 is pushed or pulled out, and the lock ball is aligned with the outer extension observation lock ball and the push protrusion 71 is removed. When the force applied to the removal of the rock projections by the elasticity of the lock protrusion 72 is inserted into the lock ball 81 is to be firmly coupled to each other.

이상과 같이 구성되고 작동되는 본 고안은, 내측 연장관(8)이 외측 연장관(5)내에서 출몰 형태로 길이 가변 자재토록 록킹 결합됨에 따라, 이를 사용시 조작자의 신장이나 청소장소의 특성에 맞추어 연장관의 길이를 가변 조작 사용하므로서, 조작이 간편하고 능률적이며 청소의 효율을 높이고 종래의 제반 결점을 완벽하게 해결할 수 있는 특출한 효과가 있는 것이다.The present invention constructed and operated as described above, as the inner extension pipe 8 is locked to the variable length in the form of the appearance in the outer extension pipe 5, the use of the extension tube in accordance with the characteristics of the stretcher or cleaning place of the operator when using it By varying the length of the operation, the operation is simple, efficient, and the cleaning effect is increased, and there is an outstanding effect that can completely solve all the conventional defects.
