Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lid rotation structure of a device housing such as a transmitter/receiver of a multiplex radio device.

Conventionally, a transmitter/receiver such as a multiplex radio device has been constructed by connecting several housing units with each circuit function with waveguides or coaxial capes, and mounting them on a rack or subrack. However, with the recent development of various devices in the microwave domain and the development of dielectric filters, etc., each circuit function has been modularized and microwave strip lines have been used, making it possible to implement the same implementation form as intermediate frequency or low frequency circuits. Significant miniaturization has become possible, and it has become possible to implement all circuit functions in one housing.

In this current situation, the high frequency section is placed on the main body side of the housing,
It is desirable to be able to mount the intermediate frequency or low frequency circuit on the printed board on the lid side of the housing. In this case, the lid can be opened and closed without separating it from the housing body, and it can be easily adjusted or replaced. It is desired that it can be easily installed and removed.

As shown in Fig. 1, the device casing has a rotation center downward from the casing main body 1 which is mounted in a horizontal position, and can be opened and closed in the direction of arrow A, with a lid side 2 opening downward. configured.

By the way, as shown in the side view of FIG. 2, the so-called hinge at the center of rotation of the lid 2 is conventionally protruded integrally on both sides of the end of the housing body 1 near the joint opening on one side of the body side 1 and the lid side 2. The provided rotating shaft 3 is engaged with a rotating structure 4 having an L-shaped notch 5 integrally formed on both sides of the end of the lid 2 (the figures only show one end), In this state, the housing body 1
To open the lid 2, loosen the set screw (not shown) connecting it to the housing body 1, bring the bottom of the L-shaped notch 5 of the rotating structure 4 into contact with the rotating shaft 3, and then open the lid 2 in the direction of arrow A. Rotate.

As described above, when the lid 2 is rotated to position 2, it wraps around the bottom of the housing body 1, and as is clear from the figure, a space 7 is required between it and other devices 6 installed below. This makes it impossible to mount multiple devices at high density.

Further, even if the lid 2 is stopped at an open position of about 90', which is an intermediate state in which the lid 2 does not turn downward, a space must be secured for the thickness of the lid 2, which causes a problem of dead space.

In view of the above-mentioned conventional problems, the present invention aims to provide a lid rotating structure that does not require interference with adjacent devices or create unnecessary space when opening and closing the lid from the main body. The present invention consists of a lid having a predetermined depth and a housing main body, and a rotation center on one side of the lid that can be opened and closed. A guide fitting having a groove that receives the hinge shaft of the lid perpendicularly to the axial direction and allows the lid to move in the distance direction between the openings is provided protruding along the side surface of the lid, and a tip of the groove is provided. The lid is rotatable, and a notch is provided in the middle of the groove to allow the insertion and removal of the plunger shaft, and the tip of the guide fitting comes into contact with a wall surface of the lid when the lid is opened. The above object is achieved by having a structure that locks at a predetermined angle.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 3 is a side view of the lid in the direction of arrow B in FIG. 1, showing an embodiment of the present invention in which only the main parts are schematically shown.

In the figure, a shows the case main body 1, b shows a state in which the lid 2 is removed, figure 0 is a view in the direction of arrow C in figure a, and figure d is a view in the direction of arrow D in figure b.

Both ends of the lower side of the housing body (only one side is shown in the figure)
A guide support fitting 10 with a groove 9 that receives the hinge shaft 8 of the lid 2 and allows the lid 2 to be pulled out and moved in the E direction is attached in the direction of the arrow E, which is perpendicular to the direction of the rotation axis perpendicular to the plane of the paper. .

On one lid 2, the hinge shaft 8 is attached to a protrusion 11 that can be integrally protruded at a corresponding position (similarly, only one side is shown in the figure).
are planted protrudingly on both sides.

The guiding support fitting 10 is divided into two parts 12 at the center in order to guide the width of the protruding part of the lid, and the grooves 9 are formed in the protruding parts 13 and 13 on both sides, facing each other with the divided part 12 in between. A notch 14, 14 is provided in the middle of the grooves 9, 9 so that the hinge shaft 8 can be inserted and removed upward.

Note that the other guide support fitting and hinge shaft portion, which are not shown, also have the same configuration.

Thus, the distance between the lower end 15 of the protrusion 11 and the end 16 of the groove 9 is predetermined.

With the above configuration, the lid 2 is brought close to the housing body 1, and the hinge shaft 8 is fitted into the notch 14 of the guide support fitting 10 by falling into the fitting groove 9.

The protrusion 11 is guided along the division 12.

Then, the lid is brought close to the housing body 1 so as to face it, and is connected with screws or the like (not shown).

This state is shown in FIG. 4 in a similar side view.

Next, attach the casing body 1 to a rack (not shown), etc., and attach the lid 2.
To explain the opening procedure, remove the screws (not shown) connecting the lid 2 and the main body, and then move the lid 2 in the direction shown by arrow E.
Pull out in the direction.

At this time, the hinge shaft 8 fits into the groove 9 and is guided.

The lid 2' is at the position where the hinge shaft 8 touches the end 16 of the groove 9, and the lid 2' is rotated and tilted as shown by arrow A around this shaft position 8', and the lid 2' is rotated approximately 90 degrees to the position. The lower end 15 of the protrusion 13 comes into contact with the wall surface of the lid 2.

The relationship between this end 15, the shaft 8, and the groove end 16 is such that, in the illustrated state, further rotation of the lid is prevented. ′ do not touch.

It will be easily understood that the inclination angle position 2' of the lid 2 can be arbitrarily determined by appropriately selecting the lengths of the guide support fittings and the grooves 9.

Further, when removing the lid 2, the hinge shaft 8 is positioned in a notch 14 provided in the middle of the groove 9, and the entire lid side 2 is lifted up.

As described above, according to the present invention, the lid is rotated at the end of the groove by providing a groove in the housing body as a guide support that receives the hinge shaft in a direction orthogonal to the rotation axis direction and allows the lid to be pulled out and moved. The lid can be opened and closed without hitting other adjacent units, etc. even if the lid is opened without needing space, and the lid can be opened and closed without separating it from the housing body.The lid can also be attached to and removed from the housing body. Since it is easy to use, it is extremely effective in practical use as a lid rotating structure for housings of not only communication equipment but also other electrical equipment.
