상기에 있어 받침대(12)의 좌우피니언기어(20)를 연결하는 축봉(18)에는 어느 한 지지관(16)과 인접하는 부분에 파지가 용이한 형태로서 외면에 원주를 따라 다수의 조정공(24)을 갖고 또 축봉(18)과 함께 회전하는 뭉치(26)를 스프링(28)을 이용하여 외측방향으로 탄력설치하고, 상기 뭉치(26)의 회전으로 선택된 어느 한 조정공(24)과 마주하는 받침대(12)의 지지관(16)에는 걸림봉(30)을 돌출형성한다.As described above, the shaft rod 18 connecting the left and right pinion gears 20 of the pedestal 12 is easily gripped to a portion adjacent to any one of the support tubes 16, and has a plurality of adjustment holes along the circumference of the outer surface. A bundle 26 having a shaft 24 and rotating together with the shaft 18 is elastically installed in the outward direction using a spring 28 and faces one of the adjustment holes 24 selected by the rotation of the bundle 26. The support tube 16 of the pedestal 12 to protrude from the locking bar (30).
이때 축봉(18)은 사각봉체로서 뭉치(26)가 갖는 사각의 결합공(32)을 관통하도록 하여 뭉치(26)가 축봉(18)을 따라 슬라이딩 가능하면서 회전시 함께 회전할 수 있도록 한다.At this time, the shaft rod 18 is a square rod body so as to penetrate the square coupling hole 32 having the bundle 26 so that the bundle 26 can be rotated while rotating while being slid along the shaft 18.
또한 뭉치가 축봉을 따라 슬라이딩하면서 회전시에는 함께 회전하도록 구성함에 있어 축봉은 사각 이외에도 육각이나 팔각등으로 형성하고 뭉치 (26)의 결합공 또한 육각이나 팔각등으로 형성하여 결합해 주면 된다.In addition, the shaft is configured to rotate together when rotating while rotating along the shaft, the shaft is formed in a hexagon or octagon, etc. in addition to the square, and the coupling hole of the bundle 26 is also formed in a hexagon or octagon and combined.
또한 축봉의 단면이 원형으로 구성될 경우에도 뭉치에 안내장공을 형성하여 상기 안내장공을 통하여 축봉에 안내봉을 연결고정해 주게 되면 뭉치는 축봉을 따라 안내장공에 의해 주어진 거리만큼 슬라이딩 가능하면서 회전시에는 축봉과 함께 회전할수가 있는바, 본 고안은 뭉치(26)가 축봉(18)을 따라 적정후퇴거리를 갖고 또 축봉과 함께 회전될 수 있는 구조이면 모두 만족한다.In addition, even if the cross section of the shaft is formed in a circular guide hole formed in the bundle to connect the guide rod to the shaft through the guide hole when the bundle is slidable by the guide hole along the shaft while rotating There is a bar that can be rotated with the bar, the present invention satisfies all if the bundle 26 has a proper retraction distance along the shaft 18 and can be rotated with the shaft.
본 고안은 기본적으로 받침대(12)의 좌우지지관(14)(16)에 설치된 피니언기어(20)의 회전으로 랙기어(10)를 갖는 승강대가 승강하여 높낮이가 조정된다.In the present invention, the platform having the rack gear 10 is elevated by the rotation of the pinion gear 20 installed on the left and right support pipes 14 and 16 of the pedestal 12 to adjust the height.
그러나 승강대의 높낮이 조절을 위한 피니언기어(20)의 회전을 원할 경우 스프링(28)으로 탄력설치되는 뭉치(26)를 후퇴시켜서 걸림봉(30)과의 걸림이 해지되게 한 상태에서 뭉치(26)를 원하는 방향으로 회전시켜 주게 되면 승강대의 높낮이가 조정된다.However, if you want to rotate the pinion gear 20 for the height adjustment of the lifting platform to retract the bundle 26 is installed elastically with a spring (28) in the state that the catch with the catch rod 30 is terminated (26) If you rotate in the desired direction, the height of the platform is adjusted.
또한 승강대의 높낮이 조정후 잡고 있던 뭉치(26)를 놓아주게 되면 상기 뭉치(26)는 스프링(28)의 반발력으로 전진하게 되고, 이러한 뭉치(26)의 전진시 받침대(12)의 지지관(16)으로부터 돌출형성된 걸림봉(30)은 뭉치(26) 외면에 갖는 수개의 조정공(24) 중 선택된 한 조정공(24)과 결합되고 이러한 선택된 조정공(24)과 걸림봉(30)의 결합시 뭉치(26)는 회전이 방지되므로 승강대는 조정된 높낮이를 유지하게 된다.In addition, if the bundle 26 held after the height adjustment of the platform is released, the bundle 26 is advanced by the repulsive force of the spring 28, and the support tube 16 of the pedestal 12 when the bundle 26 is advanced. The locking rod 30 protruding from the coupling rod is coupled to one of the adjustment holes 24 selected from several adjustment holes 24 on the outer surface of the bundle 26, and is coupled to the selected adjustment hole 24 and the locking rod 30. Bundle 26 is prevented from rotating so the platform is maintained adjusted height.
이와 같이 본 고안은 뭉치(26)의 회전으로 승강대의 높낮이가 조정되고 높낮이 조정후 잡고 있던 뭉치(26)를 놓아주게 되면 스프링(28)에 의한 전진으로 받침대(12)의 지지관(16)으로부터 돌출형성된 걸림봉(30)이 뭉치(26)의 선택된 조정공(24)과의 결합으로 조정된 높낮이를 유지하도록 하므로서 구조가 간단하여 제조경비와 고장발생률을 줄일 수 있고 높낮이 조절이 용이하게 이루어지며 높낮이 조정후 부품의 별도보관을 요하지 않아 불편함과 분실우려를 없애줄수가 있는 유용한 고안인 것이다.As such, the present invention adjusts the height of the platform by the rotation of the bundle 26, and releases the bundle 26 held after the height adjustment, and then protrudes from the support tube 16 of the pedestal 12 by the spring 28. Since the formed locking rod 30 maintains the height adjusted by the combination with the selected adjustment hole 24 of the bundle 26, the structure is simple to reduce the manufacturing cost and the failure rate, and the height is easily adjusted and the height is lowered. It is a useful design that can eliminate inconvenience and loss of worry because it does not require separate storage of parts after adjustment.
