본 고안은 사설교환기의 인쇄회로기판용 및 전원공급용 선반을 적층시켜 고정하기 위한 선반 적층 고정장치에 관한 것으로, 특히 선반의 조립 및 분해 작업이 용이해질 수 있게 한 것이다.The present invention relates to a shelf stacking fixing device for stacking and fixing a shelf for a printed circuit board and a power supply of a private exchange, and in particular, to facilitate the assembly and disassembly of the shelf.
종래에는 사설교환기의 인쇄회로기판용 및 전원공급용 선반을 적층고정하기 의해 제 3 도에 도시한 바와 같이 각 선반(11)의 상면에 나사공을 형성하고 이와 대응하는 하면에는 스크류 삽입공을 형성하여 조립시 각 선반을 차례로 적층시킨후 스크류 삽입공과 나사공 사이에 나사풀림 방지를 위한 스프링왓샤(13)와 고정스크류(12)를 결합하여 적층된 각 선반을 고정시켰으며, 선반이 고정된후 각 선반에 인쇄회로기판 및 전원공급 모듈을 장착하였다.Conventionally, as shown in FIG. 3, screw holes are formed on the upper surface of each shelf 11, and screw insertion holes are formed on the corresponding lower surface by stacking and fixing the shelf for the printed circuit board and the power supply of the private exchanger. After assembling each shelf in turn, the spring washer (13) and the fixing screw (12) were combined to prevent loosening of screws between the screw insertion hole and the screw hole. Each shelf was equipped with a printed circuit board and a power supply module.
그러나 상기한 종래의 구조에서는 선반(11)의 측면판에 통풍 및 분해 조립을 위한 구멍이 형성되어 있지 않기 때문에 선반(11)의 조립시에는 각 선반을 적층고정한후 선반(11)내부에 인쇄회로기판 및 전원공급 모듈을 장착하여야 했고 반대로 선반의 분해시에는 1차적으로 선반에 장착된 내장품을 모두 꺼낸 후 분해 조립용 공구(예를 들어 스패너등)를 선반의 안쪽으로 넣고 고정스크류(12)를 풀어주어야 했다.However, in the conventional structure described above, since the holes for ventilation and disassembly are not formed in the side plates of the shelf 11, when the shelf 11 is assembled, each shelf is laminated and fixed, and then a printed circuit is installed in the shelf 11. On the contrary, when disassembling the shelf, take out all the internal components mounted on the shelf and insert the disassembly tool (e.g., spanner) into the inside of the shelf and insert the fixing screw (12). I had to let go.
따라서 교환기의 이동 또는 사용자의 필요에 따라 선반을 분해할때 분해 작업이 매우 번거롭고 인쇄회로기판 및 전원공급 모듈등의 부품이 손상될 우려가 많으며, 또한 각 선반이 고정스크류(12)와 스프링왓샤(13)에 의해 단순 결합되는 구조이어서 선반에 외력이나 진동이 가해지는 경우 흔들림으로 인한 고정스크류(12)의 풀림현상이 발생하여 고정스크류(12)가 선반으로부터 이탈할 우려가 있음은 물론 선반간의 마찰로 인해 도장이 벗겨지기 쉬운 문제점이 있다.Therefore, when dismantling the shelf according to the movement of the exchanger or the user's needs, the disassembly work is very cumbersome, and there is a possibility that parts such as a printed circuit board and a power supply module may be damaged, and each shelf may have a fixing screw 12 and a spring washer ( 13) Since the structure is simply coupled by the external force or vibration applied to the shelf, loosening of the fixed screw 12 due to shaking occurs, there is a fear that the fixed screw 12 may be separated from the shelf, as well as friction between the shelves Due to the problem that the paint is easy to peel off.
본 고안은 선반에 외력이나 충격이 가해지는 경우에도 스크류가 쉽게 풀리거나 이탈되지 않고 또 선반의 분해 조립작업이 용이해질수 있는 개선된 구조의 장치를 제공하기 위한 것인바, 이를 첨부된 도면 제 1 도와 제 2 도를 참조하여 더욱 상세히 설명하면 다음과 같다.The present invention is to provide a device of an improved structure that does not easily loosen or detach the screw even when an external force or impact is applied to the shelf and can be easily disassembled and assembled work of the shelf, it is attached to the first drawing A detailed description with reference to FIG. 2 is as follows.
통풍공(2)를 가진 선반(1)의 상면에 고정나사(3)를 용접고정하여 상방으로 돌출된 나사부에 방진고무(4)를 끼우고 이와 대응하는 하면에는 브라켓(5)을 용접함과 함께 이 브라켓(5)의 구멍에 나사공(7)과 멈춤링(8)을 가진 세트스크류(6)을 삽입하여 세트스크류(6)의 회전에 따라 고정나사(3)가 세트스크류(6)의 나사공(7)으로 끼워져 결합될 수 있게한 것이다.Weld and fix the fixing screw 3 on the upper surface of the shelf 1 having the ventilation hole 2, and insert the anti-vibration rubber 4 into the threaded portion projecting upward, and weld the bracket 5 to the lower surface corresponding thereto. The set screw (6) having the screw hole (7) and the stop ring (8) is inserted into the hole of the bracket (5). As the set screw (6) rotates, the set screw (3) of the set screw (6) It is to be fitted into the screw hole (7) to be coupled.
도면중 미설명 부호 9는 나사의 풀림방지를 위한 스프링왓샤이다.In the figure, reference numeral 9 is a spring washer for preventing loosening of the screw.
이와같이 구성된 본 고안은 여러개의 선반(1)을 차례로 적층시켜 제 2 도에 일점쇄선으로 도시한 바와같이 각 선반(1)의 하면에 고정된 고정나사(3)와 상면 브라켓(5)에 삽입된 세트스크류(6)가 수직상으로 일치한 상태에서 선반(1)측면에 형성된 통풍공(2)으로 분해 조립용 공구를 넣고 세트스크류(6)를 조임방향으로 회전시키면 제 2 도에 실선과 같이 고정나사(3)가 세트스크류(6)에 형성된 나사공(7)으로 끼워져 견고히 고정되고, 반대로 선반(1)을 분해할때에는 선반에 내장품이 모두 장착되어 있는 상태에서 통풍공(2)을 통해 공구를 넣고 세트스크류(6)를 풀림방향으로 회전시켜 간단히 분해할 수 있게 된다.The present invention configured as described above is stacked on a plurality of shelves (1) in turn and inserted into the fixing screw (3) and the upper bracket (5) fixed to the lower surface of each shelf (1) as shown by a dashed line in FIG. When the set screw 6 is vertically aligned, the disassembly tool is inserted into the vent hole 2 formed on the side of the shelf 1, and the set screw 6 is rotated in the tightening direction to fix the solid screw as shown in FIG. The screw (3) is screwed into the screw hole (7) formed in the set screw (6) and is firmly fixed. On the contrary, when disassembling the shelf (1), the tool is opened through the vent hole (2) while all the internal parts are mounted on the shelf. And set screw 6 can be disassembled simply by rotating in set direction.
따라서 선반의 분해시 선반내에 장착된 인쇄회로기판 및 전원공급 모듈등 내장품을 모두 꺼낸후에야 분리가 가능했던 종래의 구조에 비해 선반의 분해 작업이 용이해지고 분해작업에 따른 내장품의 손상을 방지할 수 있게 된다.Therefore, when disassembling the shelf, it is easier to disassemble the shelf and prevent damage to the internal parts due to the disassembly work, compared to the conventional structure in which the internal parts such as the printed circuit board and the power supply module which are mounted in the shelf can be removed after being removed. do.
또 사용중 선반에 외력이나 충격이 가해지는 경우에도 그 충격을 방진고무(4)가 흡수할 수 있어 충격에 의한 나사풀림 현상이 덜 발생하게 되고 방진고무(4)에 의해 각 선반사이에 간격이 생겨 선반간의 마찰로 인한 도장의 벗겨짐 현상을 사전에 방지할 수 있으며, 또 장기간 사용에 따라 세트스크류(6)가 풀리는 경우에도 멈춤링(8)에 의해 세트스크류(6)가 브라켓(5)에서 이탈하지 않게 되므로 부품의 손실을 방지할 수 있게 된다.In addition, even when an external force or impact is applied to the shelf during use, the shockproof rubber 4 can absorb the shock, so that the loosening of the screw occurs less by the shock and the gap between the shelves is caused by the vibrationproof rubber 4. Peeling of the coating due to friction between the shelves can be prevented in advance, and the set screw 6 is separated from the bracket 5 by the stop ring 8 even when the set screw 6 is loosened due to long term use. This prevents the loss of parts.
