본 고안은 진공청소기의 연장관을 서로 연결하는 결합장치에 관련된 것으로서, 특히 고정링과 결합구조를 이용하여 인접하는 연장관을 용이하게 결합하거나 분리시킬 수 있도록 한 결합장치에 관한 것이다.The present invention relates to a coupling device for connecting the extension tubes of the vacuum cleaner to each other, and more particularly, to a coupling device that can be easily coupled or separated by an adjacent extension tube using a fixing ring and coupling structure.

일반적으로 진공청소기는, 제1도에 도시된 바와같이, 본체(1)와 흡입구(7)사이를 호스(3), 호스 연결관(4) 및 연장관(5a, 5b)으로 연결하여 사용하였다.In general, as shown in FIG. 1, the vacuum cleaner was used by connecting the main body 1 and the suction port 7 with the hose 3, the hose connecting pipe 4, and the extension pipes 5a and 5b.

그리고, 상기 인접하는 두 개의 연장관(5a, 5b)은 결합장치를 이용하여 동축선상에서 서로 연결하여 사용하였으며 상기 결합장치는 제2도 및 제3도에 도시된 바와 같이 연장관(5a, 5b) 및 스프링 고정구(8)로 구성되었다.In addition, the two adjacent extension pipes 5a and 5b were connected to each other on a coaxial line using a coupling device, and the coupling device was extended to the extension pipes 5a and 5b as shown in FIGS. It consists of a spring fixture (8).

연장관(5a, 5b)은 단부에 스프링고정구(8)의 돌출머리(8a)를 끼우기 위한 통공(9a, 9b)을 각각 뚫고, 일측의 연장관(5a)의 외경을 타측 연장관(5b)의 내경이하의 칫수로 형성한다.Extension pipes (5a, 5b) through the through holes (9a, 9b) for fitting the projection head (8a) of the spring fixture 8 to the end, respectively, the outer diameter of one extension pipe (5a) is less than the inner diameter of the other extension pipe (5b) Form with the dimensions of.

또한 스프링고정구(8)은 탄성을 가지는 재질로 형성하고, 그 형상을 원통형상으로 형성하되, 이주면중 소정구간을 절개하고, 스프링 고정구(8)의 외경은 상기 연장관(5a, 5b)중에서 적은 외경칫수를 가지는 연장관(5a) 내경 칫수 이상의 칫수로 형성하여 스프링 고정구(8)를 연장관(5a)의 내경에 끼워넣으면 스프링 고정구(8)은 탄력을 가진 상태에서 연장관(5a)의 내주면에 밀착하도록 하였다.In addition, the spring fastener (8) is formed of a material having elasticity, the shape is formed in a cylindrical shape, the predetermined section of the migration surface is incised, the outer diameter of the spring fastener (8) is less in the extension pipe (5a, 5b) Extension pipe (5a) having an outer diameter dimension formed by the dimensions of the inner diameter or more dimensions to insert the spring fastener (8) in the inner diameter of the extension pipe (5a) so that the spring fastener (8) is in close contact with the inner peripheral surface of the extension pipe (5a) It was.

그러므로, 연장관(5a, 5b)을 연결하고자 하는 경우에는 스프링고정구(8)를 연장관(5a)의 내경에 탄력적으로 끼워넣으며, 상기 연장관(5a)을 또다른 연장관(5b)의 내경에 끼워 넣되, 상기 스프링고정구(8)의 돌출머리(8a)가 연장관(5a)의 통공(9a)을 통과한 상태에서 또 다른 연장관(5b)의 통공(9b)을 연이어 관통하도록 하여 양 연장관(5a, 5b)을 연결하였다.Therefore, in the case of connecting the extension pipes 5a and 5b, the spring fixture 8 is elastically fitted into the inner diameter of the extension pipe 5a, and the extension pipe 5a is inserted into the inner diameter of another extension pipe 5b, Both extension pipes 5a and 5b are provided so that the protruding head 8a of the spring fixture 8 passes through the through hole 9b of another extension pipe 5b in a state in which the protruding head 8a passes through the through hole 9a of the extension pipe 5a. Connected.

그리고 연결된 상태의 연장관(5a, 5b)을 분리시키고저 하는 경우에는 스프링고정구(8)의 돌출머리(8a)를 연장관(5b)의 외부에서 눌러 돌출머리(8a)가 통공(9b)을 이탈하도록 한 상태에서 양 연장관(5a, 5b)에 힘을 반대 방향으로 가해 양 연장관(5a, 5b)을 서로 분리시켰다.When the extension pipes 5a and 5b in the connected state are separated, the protruding head 8a of the spring fastener 8 is pushed out of the extension pipe 5b so that the protruding head 8a leaves the through hole 9b. In one state, force was applied to both of the extension tubes 5a and 5b in the opposite direction to separate the extension tubes 5a and 5b from each other.

그러나, 아기와 같은 종래 결합장치는 별도의 스프링 고정구를 구비해야 하므로 생산 비용이 높을 뿐만 아니라 연결되어 있는 양 연장관을 분리시킬 때 손가락으로 돌출머리를 눌러야 하므로써 사용에 많은 분편이 있었다.However, conventional coupling devices such as babies have to be provided with separate spring fasteners, so that the production cost is high and there are many fragments in use because they have to press the protruding head with fingers when separating the two extension pipes that are connected.

따라서, 본 고안은 연장관의 연결 또는 분리가 손쉽게 이루어 질수 있고, 구조가 간단하게 이루어지는 결합 장치를 제공함에 그 목적이 있다.Accordingly, the present invention has an object to provide a coupling device that can be easily connected or disconnected extension tube, the structure is simple.

본 고안은 이를 위하여 연장관의 일단부에 결합구조를 형성하고, 고정링에는 내주면에 안내턱을 형성함과 아울러 외주면에 돌기를 형성하되 고정링의 외주면중 일부 구간을 절대하며, 상기 연장관의 결합구조에 끼워지는 또다른 연장관의 단부에는 외주연에 걸림턱을 상기 걸림턱의 일부구간을 절개하여 안내홈을 형성하였다.The present invention forms a coupling structure at one end of the extension tube for this purpose, the guide ring is formed on the inner circumferential surface and a protrusion is formed on the outer circumferential surface of the fixing ring, but a part of the outer circumferential surface of the fixing ring is absolute, and the coupling structure of the extension tube At the end of the other extension tube to be fitted in the engaging jaw to the outer periphery was formed by guiding the cutting section of the engaging jaw.

이와 같이 본 고안은 상기 고정링을 매개로 하여 두 개의 연장관을 동축선상에 연결할 수 있도록 한 것으로서 이를 첨부한 도면에 도시된 본 고안의 실시예에 따라 상술하면 다음과 같다.As such, the present invention allows the two extension tubes to be connected on the coaxial line through the fixing ring, and according to the embodiment of the present invention shown in the accompanying drawings, the following is as follows.

본 고안은, 제4도에 도시된 바와 같이, 일측 연장관(5b)의 연결부위인 일단부에 결합구조의 결합부(10b)를 형성하고, 상기 결합부(10b)에 통공(11)을 뚫는다.According to the present invention, as shown in FIG. 4, the coupling portion 10b of the coupling structure is formed at one end of the connection portion of the one extension tube 5b, and the through hole 11 is drilled in the coupling portion 10b. .

상기 연장관(5b)의 내경에 끼워지는 또 다른 연장관(5a)의 연결부위인 단부에는 걸림턱(13)을 형성하되 상기 걸림턱(13)의 소정구간을 절개하여 안내홈(12)을 형성하고, 상기 걸림턱(13)의 후부에는 고정링(14)의 안내턱(14a)이 끼워지는 공간인 안착홈(16)을 형성한다.The hooking jaw 13 is formed at the end of the connection portion of the other extension pipe 5a inserted into the inner diameter of the extension pipe 5b, and the guide groove 12 is formed by cutting a predetermined section of the locking jaw 13. The rear end of the locking jaw 13 forms a seating groove 16 which is a space into which the guide jaw 14a of the fixing ring 14 is fitted.

상기 안착홈(16)을 형성하는 바닥면(16a)은 연장관(5b)의 중심점을 기준하여 편심되게 형성하여 상기 중심점으로부터 바닥면(16a)까지의 거리가 점진적으로 변화되게 형성한다.The bottom surface 16a forming the seating groove 16 is formed to be eccentric with respect to the center point of the extension pipe 5b so that the distance from the center point to the bottom surface 16a is gradually changed.

그리고, 고정링(14)은 일부 구간이 절개된 형태의 원통형체로 형성하고, 내주면에는 안태넉(14a)을 일체로 형성하며, 외주면에는 돌기(14b)를 일체로 형성한다.In addition, the fixing ring 14 is formed as a cylindrical body in which some sections are cut, the inner circumferential surface is formed integrally 14a, and the outer circumferential surface is integrally formed with a projection (14b).

그러므로, 연장관(5a, 5b)을 연결하여 결합시키고자 하는 경우에는 고정링(14)을 결합부(10b)에 탄력적으로 끼워 넣으면 돌기(14b)가 통공(11)에 끼워져 고정링(14)은 연장관(5b)에 결합된다.Therefore, in the case where the extension pipes 5a and 5b are connected to each other and the fixing ring 14 is elastically inserted into the coupling portion 10b, the protrusion 14b is fitted into the through hole 11 so that the fixing ring 14 is It is coupled to the extension pipe 5b.

이어서 연장관(5a)의 안내홈(12)을 고정링(14a)의 안내턱(14a)에 끼워 넣은 뒤, 제5a도에 도시된 바와 같이 연장관(5a)을 밀어 넣은다.Subsequently, the guide groove 12 of the extension tube 5a is inserted into the guide jaw 14a of the fixing ring 14a, and then the extension tube 5a is pushed in as shown in FIG. 5A.

이때 연장관(5a)를 돌리면 제5b도에 도시된 바와 같이 안내턱(4a)이 안착홈(16)에 끼워진 상태에서 편심된 바닥면(16a)이 안내턱(14a)을 전짐적으로 압박하게 되므로 양 연장관(5a, 5b)은 연결된다.At this time, when the extension tube 5a is rotated, as shown in FIG. 5B, the eccentric bottom 16a in the state where the guide jaw 4a is fitted into the seating groove 16 compressively compresses the guide jaw 14a. Both extension pipes 5a and 5b are connected.

또한 결합된 상태의 연장관(5a, 5b)을 분리시키고자 하는 경우에는 양 연장관(5a, 5b)을 서로 다른 방향으로 회전시키고 이로인해 안내홈(12)이 안내턱(14a)으로부터 이탈하게 되어 연장관(5a, 5b)을 분리시키게 된다.In addition, in order to separate the extension pipes 5a and 5b in a coupled state, the two extension pipes 5a and 5b are rotated in different directions, thereby causing the guide groove 12 to be separated from the guide jaw 14a. (5a, 5b) will be separated.

이와같이 본 고안은 연장관의 결합 구조가 간단하여 생산 비용이 절감되며, 연장관의 결합력이 양호하여 양 연장판을 결합한 뒤 유동이 없어지고, 양 연장관의 결합이 양 연장관을 돌려서 이루어지므로 사용이 편리해지는 작용효과가 있다.As such, the present invention has a simple coupling structure of the extension pipe to reduce the production cost, and the coupling force of the extension pipe is good, so that the flow is lost after combining the two extension plates, and the operation of the two extension pipes is made by turning both extension pipes. It works.
