Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a board removing structure mounted on a chassis such as a housing.

[0002]

2. Description of the Related Art An example of a conventional substrate punching structure will be described with reference to FIGS.

[0003] 1 is a chassis, 2 is a board, 14 is a handle,
15 is a component of the handle 14, which is a rotation axis, and 16, 17 are handles
14 components, projection 20; force applied to projection 16; 21 projection
A force acting on 17 and 22 are forces acting on the substrate 2.

[0004] The board 2 is mounted on the chassis 1, and a handle 14 is attached to the board 2 via a rotating shaft 15.

In order to remove the substrate 2 from the chassis 1,
A force 20 is applied to the protrusion 16 as shown in FIG. The projection 16 is a handle
Due to the fourteen components, the handle 14 rotates around the rotation shaft 15 as a fulcrum. Since the projection 17 is a component of the handle 14, a force 21 acts to push the chassis 1 by rotating the handle 14. However, since the chassis 1 is absolutely fixed and held, the chassis 1 does not actually move, and a force 22 in a direction opposite to the force 21 acts on the substrate 2 as shown in FIG. Moves in parallel and is removed from the chassis 1.

[0006]

Problems to be solved by the present invention will be described with reference to FIG.

[0007] In the above-mentioned conventional board removing structure, when a plurality of boards are mounted on the chassis 1, the handle is not used.
Since 14 is attached to each substrate 2, there is a disadvantage that the mounting operation of the handle 14 to each substrate 2 must be performed in order to mount it on the chassis 1. When the board 2 is replaced for maintenance or the like, the handle 14
Must also be replaced together. This replacement of the handle 14 has the disadvantage of increasing costs in terms of both materials and man-hours.

An object of the present invention is to provide a substrate punching structure in which the above-mentioned disadvantages are eliminated.

[0009]

According to the present invention, a guide hole is provided in a chassis to achieve the above object, and the handle moves along the guide hole when the handle is attached to the chassis. Further, a first projection to be inserted into the hole at the end of the substrate is provided, and a second projection orthogonal to the first projection is provided. As a result, the first protrusion is inserted into the hole at the end of the board, and the handle is rotated by applying force to the second protrusion. With the attached handle, it is possible to remove a plurality of substrates.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A substrate cutting structure according to an embodiment of the present invention will be described with reference to FIGS. 1 to 5 and FIG.

Reference numeral 4 denotes a handle of this embodiment, 3 denotes a hole of a component of the substrate 2, 11 denotes a component of the chassis 1, and a guide hole.
Is a component of the handle 4 and a rotation axis, and 6 and 7 are handles 4
Is a force applied to the protrusion 6, 9 is a force acting on the handle, and 10 is a force acting on the substrate 2.

The board 2 is mounted on the chassis 1, and the handle 4 is mounted on the guide hole 11 via the rotating shaft 5. The projection 7 is located at a position to enter the hole 3.

The guide hole 11 has a shape as shown in FIG. 5, and the handle 4 is attached to the guide hole 11 via the rotary shaft 5, so that the handle 4 freely moves in parallel on the guide hole 11.

In order to remove the substrate 2 from the chassis 1,
A force 8 is applied to the protrusion 6 as shown in FIG. Since the handle 4 is attached to the chassis 1 by the rotation shaft 5, a force 9 is applied, and the handle 4 rotates around the rotation shaft 5 as a fulcrum. Since the projection 7 is a component of the handle 4, the handle 4 rotates to move in a similar manner to the substrate 2 with the rotation shaft 5 as a fulcrum, and enters the hole 3 as shown in FIG. A force 10 acts so as to push the inner wall of the board 3, and the board 2 moves in parallel as shown in FIG.

As shown in FIG. 5, the handle 4 is located at a position where the leftmost substrate 2 is to be pulled out. By freely moving the guide hole 11 in parallel, as shown in FIG. You can move to the position.

As described above, all the three boards 2 can be pulled out only by the handle 4, and a plurality of boards can be replaced without replacing the handle together at the time of maintenance replacement.

A method of attaching the handle 4 to the chassis 1 will be described with reference to FIG. The handle 4 is divided into a handle upper portion 23 and a handle lower portion 24. A projection 7 and a D-axis (a shaft having a D-shaped cross section) 25 are provided on the upper handle 23 and the lower handle 24.
Are provided with a projection 6 and a D hole (a hole having a D-shaped cross section; a hole into which a D-axis 25 is inserted). Further, a screw hole 27 is provided in the D-axis 25. After the D shaft 25 is inserted into the guide hole 11, the handle 4 can be attached to the chassis 1 by inserting the chassis 1 into the D hole 26 and sandwiching the chassis 1 between the upper handle 23 and the lower handle 24 with screws 28.

[0018]

The effects of the present invention will be described.

According to the present invention, the required number of handles for removing a board is satisfied by one board (two handles: a handle attached to the upper part of the chassis and a handle attached to the lower part of the chassis). Material cost and man-hours for mounting are unnecessary, and the cost can be reduced.
