본 고안은 진공청소기의 바퀴에 관한 것이다.The present invention relates to a wheel of the vacuum cleaner.

종래에는 제2도에 도시한 바와 같이 삽입관(13)이 일체로 형성된 바퀴(4)를 진공청소기 몸체(1)에 결합시켰으나 이는 구조가 간단하고 제작비용이 저렴하게 드는 장점이 있기는 하나, 전체적으로 취약하여 진공청소기의 자중에 의해 삽입관 (13)이 연장되는 부위(13')가 전단되거나 사용중 장애물에 부딪히거나 하여 외륜부(4')가 깨져버리는 등의 문제점이 있었다. 이러한 문제점을 고려하여 제3도에 도시한 바와 같이 바퀴( 4)내에 내측커버(7)와 외측커버(8)을 결합하고 여기에 따로 고정판(18)을 결합하여 이를 진공 청소기 몸체(1) 하단에 나사(16)로서 결합한 바퀴를 사용하였으나, 이 또한 견고하기는 하나 부품수가 많아 조립이 번거롭고 금형제작 비용이 많이 소요되는 문제점이 있었다.Conventionally, as shown in FIG. 2, the wheels 4 integrally formed with the insertion tube 13 are coupled to the vacuum cleaner body 1, but this has the advantage of simple structure and low manufacturing cost. There is a problem that the outer ring portion 4 'is broken due to the overall weakness and the portion 13' where the insertion tube 13 extends due to the weight of the vacuum cleaner is sheared or hits an obstacle during use. In consideration of these problems, as shown in FIG. 3, the inner cover 7 and the outer cover 8 are coupled to the wheels 4, and the fixing plate 18 is coupled to the wheel 4 to lower the vacuum cleaner body 1. Although the wheel was used as a screw 16, but this is also robust, but the number of parts, there is a problem in that the assembly is cumbersome and mold manufacturing costs are high.

본 고안은 상기와 같은 문제점을 감안하여 안출된 것으로 부품수가 감소되면서 충분한 강도를 유지할 수 있는 진공청소기의 바퀴를 제공함에 그 목적이 있다.The object of the present invention is to provide a wheel of a vacuum cleaner that can maintain sufficient strength while reducing the number of parts to be devised in view of the above problems.

이하, 본 고안을 첨부된 도면에 의하여 상세히 설명한다면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도에 도시한 바와 같이 진공 청소기 몸체(1)의 양측의 바퀴 결속 부위에 외부로 연장관(2)이 형성되고, 내부가 공간부로 형성된 바퀴(4) 외측면에는 단턱(5)이 형성되어 있으며 내측면에는 환상의 걸림턱(6)이 형성된다.As shown in FIG. 1, an extension tube 2 is formed at the outside of the wheel binding portions of the vacuum cleaner body 1, and a step 5 is formed at an outer surface of the wheel 4 formed as a space. The inner side is formed with an annular locking jaw (6).

한편, 이에 결합되는 외측 커버와 내측커버(8)를 마련하되, 상기 외측 커버(7)에는 중앙의 나사공(9)이 형성된 돌부(10)가 일체로 형성되고 상기 내측 커버(8)는 내측으로 절결홈(11)과 걸림돌기(12)가 형성된 삽입관(13)이 형성되고 그 둘레에 상기 연장관(2)를 감싸주는 수납공간부(14)가 형성되면 상기 내측 커버(8)의 외측으로는 내륜부(15)가 형성되어 있다.Meanwhile, an outer cover and an inner cover 8 coupled thereto are provided, and the outer cover 7 is integrally formed with a protrusion 10 having a central screw hole 9 formed therein, and the inner cover 8 has an inner side. When the insertion tube 13 formed with the cutout groove 11 and the locking projection 12 is formed and the receiving space portion 14 surrounding the extension tube 2 is formed around the outer side of the inner cover 8 Inner ring part 15 is formed.

도면중 설명부호(17)은 결합공이다.In the figure, reference numeral 17 is a coupling hole.

이와같이 구분된 본 고안은 상기 바퀴(4)의 단턱(5)에 상기 외측 커버(7)가 걸리도록 하여 결합하고 상기 내측커버(8)의 내륜부(15)가 상기 걸림턱(6)을 극복하도록 강제로 내측커버(8)을 눌러 바퀴(4) 내부에 결합하여 나사(16)으로 외측커버(7)와 내측커버(8)을 결속 고정한후 상기 내측커버(8)의 삽입관(13)을 진공청소기 몸체 (1)에 형성된 연장관(2)에 밀어 끼워 주게되면 삽입관(13)이 오므라지면서 삽입되는 동시에 삽입관(13)의 단부에 형성된 걸림돌기(12)가 진공청소기 몸체(1) 내벽(3)에 걸려져 이탈이 방지되는 상태로 바퀴(4)의 회전축 역활을 하게 된다. 여기서, 상기 외측 커버(7)의 돌부(10)는 나사(13)에 의해 상기 내측 커버(8)과 결속고정되어 상기 삽입관 (13)과 동일축상에 위치하게 됨으로써 상기 삽입관(13)의 취약부분(13')의 강도를 보강해 주는 역할을 한다.The present invention divided as described above is coupled to the stepped portion 5 of the wheel 4 so that the outer cover 7 is engaged, and the inner ring portion 15 of the inner cover 8 overcomes the locking step 6. Press the inner cover (8) to force the inside of the wheel (4) so as to bind the outer cover (7) and the inner cover (8) by the screw 16 and then the insertion tube (13) of the inner cover (8) Is inserted into the extension tube (2) formed in the vacuum cleaner body (1) when the insertion tube 13 is retracted and inserted at the same time the locking projection 12 formed at the end of the insertion tube 13 is the vacuum cleaner body (1) The inner wall (3) is caught and acts as a rotating shaft of the wheel (4) in a state that the separation is prevented. Herein, the protrusion 10 of the outer cover 7 is fixed to the inner cover 8 by a screw 13 to be positioned on the same axis as the insertion tube 13 so that the insertion tube 13 is closed. It serves to reinforce the strength of the weak portion (13 ').

이와같이 본 고안은 종래 바퀴에 비해 부품수가 적게 들면서도 충분한 강도를 유지할 수 있으므로 매우 경제적이고 실용적인 고안인 것이다.As such, the present invention is a very economical and practical design because it can maintain sufficient strength while reducing the number of parts compared to the conventional wheels.
