Must be placed higher.

In addition, the pull-out structure is such that the ridge 113 of the chassis 101, the connector 112, and the cable 107 have a surface so as not to hit the front frame of the housing 100, the mounting position of the connector 112 is lowered, and the cable 107 has low rigidity. It is necessary to select, the restriction in the design of the chassis 101 occurs, and the mounting area of the board and parts is reduced, and the slide rail 109 also has the load of the housing 100 and the chassis 101, the length of the chassis 101, the chassis 101 and the mounting position. Regulated by etc., slide rail 1
It often happens that the specifications of 09 itself are exceeded, and some of them do not have a rotating mechanism, so it takes time for maintenance and adjustment, and a lot of space is required. Housing 100 on it
Requires a lot of space between the ceiling of the room and the ceiling of the room, and if there is not enough space, lower the chassis and reconnect the cable 107,
The biggest problem, such as the need to perform maintenance, occurred and we could not obtain a technically satisfactory product.

The present invention has been made in view of the above-mentioned points, and does not require a stepping stone when adjusting and maintaining the chassis at a high position,
It is an object of the present invention to eliminate the above-mentioned various restrictions in the design of a chassis, reduce the load applied when the chassis rotates, and provide a chassis drawer structure suitable for adjustment and maintenance.

[Means for Solving the Problems]

In order to solve the above problems, the present invention has a chassis drawing structure as described below.

In a panel chassis that is equipped with a slide rail and is mounted in a housing and can be pulled out, a side plate to which the slide rail is mounted and a chassis portion on which a component, a board, etc. are mounted are separated, and a pressure damper is provided on a side surface of the housing. , The side plate and the chassis portion are mutually connected through a shaft,
The structure is such that the chassis can be rotated via the shaft, a hook is attached to the upper surface of the rear part of the chassis, and a moving hook is attached to the upper part of the front of the chassis at a position where the hook meshes with the hook, and the moving hook and the pressure damper are connected by a wire. When the panel chassis is pulled out from the housing, the hooks on the upper surface of the rear portion of the chassis and the moving hooks on the upper portion of the front surface of the housing are engaged with each other and interlock with the chassis portion that rotates about the axis to come out.

[Action]

By constructing the chassis pull-out structure as described above, the side plate and the chassis part are divided, and the chassis part can be rotated downward by the shaft, so that the shelf box part of the chassis part on which the components such as the board are mounted is lowered. It is easy to adjust and replace the board and parts. In addition, since the pressure damper is connected to the moving hook attached to the upper part of the front surface of the housing by the wire, the pressure of the pressure damper increases and the load on the chassis portion gradually decreases when the chassis portion rotates.
