Description

[Detailed Description of the Invention] The present invention relates to a fixing structure for detachably fixing a box-shaped device with a lid to a base.

A description will be given below using a car telephone radio device as an example.

FIG. 1 shows an outline of this car telephone radio device, and as shown in the figure, it is composed of a box-shaped main body 1 that houses a radio device (not shown) and a lid 2. Attachment is such that it is fixed to the stand 3 using a hook 4 and fixing means such as screws.

In order to prevent tampering and theft, such devices are normally installed so that they cannot be easily removed from the base 3 and the lid cannot be opened easily, and should be removed in the event of a breakdown or maintenance inspection. The attachment must be made so that it can be easily removed from the stand.

The present invention was devised based on this requirement.

For this reason, the present invention has a fixed structure in which a box-shaped device with a lid is detachably fixed to a base, and the device is attached at the tip with a hook that engages with the hook-shaped hook portion of the base. A cylinder lock is formed by including an outer cylinder having an outer cylinder, and an inner cylinder which is always pressed outward by a spring inserted into the outer cylinder and is movable only in the axial direction within the outer cylinder, A cylinder lock is attached to the main body of the device so as to be rotatable through an angle of 90 degrees, a rectangular plate-shaped handle for closing the lid is attached to the upper end of the inner cylinder, and the inner cylinder of the cylinder lock is attached to the outer cylinder. The device is characterized in that a recessed portion is formed in the main body and the lid to prevent rotation of the handle when the handle is locked with a push-in key.

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

FIG. 2 shows an exploded perspective view of the embodiment.

In the figure, 1 is the main body, 2 is the lid, 5 is the outer cylinder of the cylinder lock, 6 is the spring, 7 is the inner cylinder of the cylinder lock, 8 is the handle fixed to the end of the inner cylinder, 9 is the washer, and 10 is the Natsuto, 11
1 is a hook, and 12 is a bolt. The main body 1 has a cylindrical portion 1a for accommodating a cylinder lock and a recess 1b for housing a handle 8. The lid 2 also has a recess 2a for receiving a part of the handle 8. It is formed.

Note that the upper fan-shaped portion 1 of the cylindrical portion 1a provided in the main body 1
c is the protrusion 5 when the outer cylinder 5 of the cylinder lock is inserted.
This serves as a stopper for the outer cylinder 5 to limit the rotation angle to 90'.

Alternatively, the protrusion may be provided in the X portion and the groove may be provided in the Y portion.

Further, the inner cylinder 7 of the cylinder lock is provided with a screw 7c and a lock pin 7b that can be moved in and out by key operation, and the outer cylinder 5 has a guide hole 5b into which the screw 7a of the inner cylinder is inserted, and a hole 5C into which the lock pin 7b is inserted. is formed.

Further, a notch 11a is formed in the flange portion of the hook 11.

Each member thus formed is assembled as shown in FIG.

The assembly order is to attach the bundle 8 in advance, remove the screw 7a,
The inner cylinder 7 with the lock pin 7b retracted is moved to the outer cylinder 5 together with the spring 6.
and assemble the screw 7a to the inner cylinder 7 through the guide hole 5b.

Next, the outer tube 5 is inserted into the cylindrical portion 1a of the main body 1, the washer 9 is fitted from below and tightened with the nut 10, and the hook 11 is attached with the bolt 12.

At this time, the direction of the notch 11a of the hook 11 is made to match the longitudinal direction of the bundle 8.

Next, the operation of this embodiment assembled in this manner will be described.

First, as shown in FIG. 4, after engaging the hook hole 13 provided at the rear of the main body 1 with the hook portion 4 of the base 3,
When installing the main body 1, rotate it in the direction of arrow P until it touches the base 3.

At this time, during attachment, the hook portion 4a provided on the stand 3 passes through the cutout portion 11a of the hook fitting 11.

Next, when the bundle 8 is rotated 90 degrees counterclockwise, the hook 11 rotates and engages with the hook part 4a of the mounting base 3, as shown in FIG. Fix it.

Next, as shown in FIG. 6, the rear part of the lid 2 is engaged with the groove 14 formed in the rear part of the main body 1, and the bundle 8 is pushed down in the direction of the arrow Q, and the cylinder lock is operated with the key 15. When the lock pin 7b is engaged with the hole 5C of the outer cylinder, the inner cylinder 7 of the cylinder lock is locked to the outer cylinder 5.

In this state, the bundle 8 presses the end of the lid 2 to prevent it from opening.

Furthermore, since the bundle 8 is fitted into the recess 1b formed in the main body 1 and is prevented from rotating, the hook 11 cannot be rotated either, making it impossible to attach or remove the main body 1 using the base 3.

Next, opening the lid 2 and removing the main body 1 can be done in the reverse order as described above. When the cylinder lock is unlocked by operating the key 15, the bundle 8 pops out together with the inner cylinder 7 by the action of the spring 6, and the lid 2 is opened. be free.

Further, since the bundle 8 can be freely rotated, the hooking fitting 11 can be rotated to disengage the hook portion 4a of the mounting base 3, and the main body 1 can be removed from the mounting base 3.

Incidentally, when the lid 2 is fixed with the screw 16 as shown in FIG. 7, the bundle 8 is rotated.

It can be removed in the state shown in the figure.

As explained above, the device fixing structure according to the present invention makes it possible to fix the main body and close the lid using a single cylinder lock, which is very easy to handle.
