Description

캐스터용 바퀴{wheel for caster}Caster wheels {wheel for caster}

본 고안은 실내에서 주로 사용하는 운반기에 부착되는 캐스터용 바퀴에 관한 것으로 보다 구체적인 것은 소음이 적고 부드럽게 회전하며 바퀴축부에 이물질이 개입될 수 없도록 패킹을 형성하고 바퀴회전축이 바퀴본체에 형성된 축잡이에 견고하게 결합하여 요동없이 안정적인 회전을 할 수 있도록 구성한 것이다.The present invention relates to a caster wheel attached to a carrier mainly used in the room. More specifically, it forms a packing so that the noise is smooth and rotates smoothly, and foreign matter does not enter the wheel axle. It is firmly combined to make stable rotation without shaking.

종래의 캐스터용 바퀴는 여러가지가 공지되어 있으나 쿠션재로 된 바퀴와 바퀴가 장치되는 바퀴본체 사이에 간격이 형성되어 먼지와 같은 미세한 이물질이 쉽게 내부로 침투하여 회전축 외면에 끼이게 되므로 회전축의 회전이 방해를 받아 원활하게 회전하지 못해 소음이 발생하고 고장의 원인이 되는 불편이 있었다Conventional caster wheels are known in many ways, but a gap is formed between the wheel made of cushion material and the wheel body in which the wheels are mounted so that fine foreign matter such as dust easily penetrates inside and gets caught on the outer surface of the rotating shaft, thus preventing rotation of the rotating shaft. It could not rotate smoothly in response to noise, causing inconvenience

본 고안은 위와 같은 종래의 불편을 해소하여 수명이 오래가고 회전이 원활 한 캐스터용 바퀴가 되도록 한 것이다.The present invention is to solve the conventional inconveniences as described above to be a caster wheel is a long life and smooth rotation.

본 고안은 바퀴본체 중심부에 형성된 바퀴축부에 바퀴회전축이 억지끼움으로 결합되어 회전하도록 구성하고 바퀴본체와 바퀴체가 결합되는 접촉부에 패킹을 개재하여 미세먼지와 같은 이물질이 바퀴본체 내부로 들어갈 수 없도록 틈새막음부를 형성하여 오래 사용하여도 회전축의 회전이 뻑뻑해 지지 않는 제품이 되게 한 것이다.The present invention is configured so that the wheel rotation shaft is coupled to the wheel shaft portion formed in the center of the wheel body to rotate and through the packing on the contact portion where the wheel body and the wheel body is coupled, so that foreign matters such as fine dust cannot enter the wheel body. The blocking part is formed so that the rotation of the rotating shaft does not become stiff even after long use.

이와 같이 된 본 고안은 바퀴본체(1)에 형성된 바퀴축부에 바퀴회전축이 결합될 때 바퀴회전축 끝에 형성된 환상요입홈에 바퀴축부 속에 형성된 환상돌재가 강제 결합하므로 바퀴중심부에 형성된 바퀴회전축의 돌출부가 바퀴축부 속에 끼워지면 그 스스로 빠질 수 없게 조립되므로 결합후에 이완될 염려가 없고, 바퀴지지축은 열가소성 합성수지제이고 바퀴회전축은 금속봉체로서 합성수지제 바퀴축부 내경에 알맞게 끼워지는 규격이고, 바퀴축부에 삽입되는 바퀴회전축의 돌출부 길이가 길어서 바퀴축 내에 끼워지면 흔들림이 발생하지 않으므로 떨림이 없이 안정된 회전이 이루어질 수 있고, 바퀴본체 외주연이 바퀴와 결합되는 면부에 패킹이 개방되어 상호간에 틈새를 만들지 않으므로 미세먼지가 바퀴본체속으로 들어갈 염려가 없어, 바퀴축부와 바퀴회전축이 결합되어 있는 공간에 먼지와 같은 미세 이물질이 들 어가지 않아 오래 사용하여도 바퀴회전축에 이물질이 끼이지 않아 회전축의 회전이 방해받을 염려가 없게 되어 원활한 회전이 달성되는 이점을 가지게 된다.The present invention as described above, when the wheel rotation shaft is coupled to the wheel shaft formed on the wheel body 1, the annular recess formed in the wheel shaft portion is forced to the annular recess groove formed at the end of the wheel rotation shaft, so that the protrusion of the wheel rotation shaft formed at the center of the wheel wheel If it fits in the shaft part, it cannot be pulled out by itself, so there is no fear of relaxation after joining.The wheel support shaft is made of thermoplastic synthetic resin and the wheel rotation shaft is a metal rod that fits to the inner diameter of the wheel shaft made of synthetic resin. If the length of the protrusion of the rotating shaft is inserted into the wheel shaft, the shaking does not occur, so stable rotation can be achieved without shaking, and since the packing is opened on the surface where the outer circumference of the wheel body is combined with the wheel, it does not form a gap between each other, There's no worry about getting into the wheel body, Fine foreign matters such as dust do not enter the space where the wheel rotation shaft is coupled, so that even if used for a long time, the wheel rotation shaft does not get caught and there is no fear that the rotation of the rotation shaft will be disturbed.

그리고 본 고안의 바퀴는 바퀴본체 외주면에 고무링이 피복되어 있어서 접지회전시 쿠션을 발휘하므로 부드럽게 회전하게 되어 마찰소음도 거의 없는 이점을 가지는 것이다.In addition, the wheel of the present invention is coated with a rubber ring on the outer circumference of the wheel body, thereby exhibiting a cushion during ground rotation, thereby smoothly rotating and having almost no friction noise.

본 고안은 합성수지제로 성형되어 반구형체(100)로 되며 외면에 상향 연결관(101)이 형성되어 연결관속에 하단연결부가 끼워져서 회전하는 연결볼트(102)가 구비되고 반구형체 내면 중심부에서 개방부쪽으로 직각 돌출되게 원통형상의 축잡이(103)가 형성되어 축잡이 구멍속에 내향으로 환상돌재(104)가 형성된 바퀴본체(1)와 The present invention is formed of a synthetic resin to form a hemispherical body 100, the upper connection pipe 101 is formed on the outer surface is provided with a connecting bolt 102 is rotated by inserting the lower connection portion in the connection pipe and the opening portion in the hemispherical inner surface center A cylindrical shaft holder 103 is formed so as to project at right angles toward the wheel body 1 and the annular stone 104 is formed inward in the shaft hole.

반구형체(100)의 개방부쪽에 장치되며 합성수지제로 성형된 바퀴체(200)의 외주면에 PVC 또는 고무중에서 선택한 탄성체로 된 외륜체(201)가 피복되고 바퀴체에 중심부(200a)에 금속봉체로 된 회전축(3)이 끼워져서 바퀴체 중심부에 끼워진 회전축의 돌출부(301)가 축잡이(103)속으로 삽입되고 돌출부(301)에 형성된 환상요입홈(302)에 축잡이구멍속에 형성된 환상돌재(104)가 강제 결합하여 바퀴 회전축(3)이 형성되는 바퀴(2)와 It is installed on the open side of the hemispherical body 100 and the outer circumferential surface of the wheel body 200 formed of synthetic resin is coated with an outer ring body 201 made of an elastic body selected from PVC or rubber, and the wheel body is made of a metal rod body at the center 200a. The projection 301 of the rotation shaft inserted into the center of the wheel body is inserted into the shaft holder 103 and the annular stone 104 formed in the shaft hole in the annular recess groove 302 formed in the projection 301. ) And the wheel 2 and the wheel rotation shaft (3) is forcibly combined
