Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a movable structure of a socket base.
[0002]
[Prior art]
In the conventional apparatus shown in FIG. 8, when the socket base is movable, the operating lever is provided in the vertical direction, which is the movable direction of the socket base. However, since the operating lever is located between the fluorescent lamp and the reflector shade, It was an obstacle in the reflex shade.
[0003]
[Problems to be solved by the invention]
The present invention provides an operation lever that does not hinder the irradiation light of the lamp in the reflection shade by providing the operation lever in a horizontal direction perpendicular to the movable direction of the socket base.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, an operation lever is provided in the socket mounting portion in a horizontal direction perpendicular to the movable direction of the socket base, and is disposed inside the fixing portion to the instrument body, and the fixing portion is sandwiched from the outside. By fixing the socket mounting part with the fixing plate as described above, the fixed guide convex part of the operation lever is fixed at the guide hole position of the fixed part, and by fixing the control lever, the fixed guide convex part is fixed to the fixed part. Detach from the guide hole and enter the released state, enabling a vertical sliding structure.

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows the entire lighting fixture adopting the movable structure of the socket base of the present invention. From the fixture body 10, the socket base 20 of the movable structure of the present invention, the lamp socket 30, the reflective shade 40 and the reflective shade fixture 50, Composed.
FIG. 2 is a detailed view of the socket base of the present invention, FIG. 3 is a cross-sectional view taken along line AA ′ of the detailed view, and FIG. 4 is an exploded view of the cross-sectional view.
The socket base 20 is composed of a fixed portion 21 for fixing to the fixture body 10 and a movable portion 22 for fixing and moving the lamp socket 30. The movable portion 22 includes a socket mounting portion 221, an operation lever 222 having a spring property, and a fixed plate. 223.
[0006]
The operation lever 222 is provided with a fixed guide convex portion 224, fixed to the socket mounting portion 221, and disposed inside the fixed portion 21. Further, the fixing plate 223 is fixed to the socket mounting portion 221 so as to sandwich the fixing portion 21 from the outside. The fixed portion 21 is provided with a guide hole 211 into which the fixed guide convex portion 224 of the operation lever 222 is fitted, and is fixed at a position where the fixed guide convex portion 224 is fitted into the guide hole 211.
[0007]
FIGS. 5 and 6 are views of the socket base of the present invention in a state of being fixed at the respective guide positions. When the operating lever 222 is squeezed in the direction of arrow B, the fixed guide convex portion 224 is moved from the guide hole 211. The socket mounting portion 221 can be moved in the up and down direction indicated by the arrow C.
Further, as shown in FIG. 7, since the operation lever 222 is positioned in the horizontal direction, it does not hinder the irradiation light in the reflection shade 40 of the fluorescent lamp 60.
[0008]
【The invention's effect】
ADVANTAGE OF THE INVENTION According to this invention, the movable structure of the socket stand which can slide a socket to an up-down direction, without interfering with the irradiation light within the reflective shade of a fluorescent lamp is enabled.
