Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a device for fixing a vehicle-mounted radio device, and particularly to a fixing device that can reliably prevent the radio device from being stolen.

(Prior Art) Conventional wireless device fixing devices of this type include those that simply use screws and bolts, and those that use plate springs or coil springs to facilitate attachment and detachment.
However, they were completely defenseless against theft. Fixing devices with locks are also known as an anti-theft measure, but since the heads of screws or bolts are exposed on the outside, even if they cannot be removed easily, those screws or bolts can be removed over time. It was inevitable that the radio would be stolen after it was removed.

(Problems to be Solved by the Invention) The present invention solves the drawbacks of the prior art described above, and is capable of reliably preventing theft by locking the radio, while making it easy to attach and detach the radio. The present invention provides a fixing device for an in-vehicle radio.

(Means for Solving the Problems) The present invention is to fix the housed radio to the vehicle from the inside of the box through screw holes provided at the bottom of the rectangular box so as to cover it and hide it. a chassis for accommodating a radio device configured as such, and an opening 1C through which guide protrusions R1 provided on both sides of the radio device pass when the radio device is inserted toward the bottom of the chassis; R1 is the opening 1
When the wireless device is moved toward the rear of the chassis after being inserted to the bottom of R1, the guide protrusion R1
guide recess 1A into which is inserted and fixed, and the opening 1
a pair of guide plates attached to both inner surfaces of the chassis, and a guide protrusion 1B forming one end of the chassis; It consists of a fixture attached to the bottom of the front side, and the fixture includes:
a cam rotation shaft having a cam that rotates eccentrically by turning an attached knob; a means for converting the eccentric rotation force of the cam of the cam rotation shaft into linear motion force; and a linear motion force transmitted from the means to a push rod for moving and fixing the radio toward the rear of the chassis; a rotary cylinder lock for locking movement of the push rod at a fixed position of the radio by operating a key; and the key. The lock means is operated by the rotation of the rotating shaft of the cylinder lock due to the rotation of the cylinder lock, and locks the movement of the push rod.

(Example) Embodiments of the present invention shown in the drawings will be described in detail below.

FIG. 1 shows an embodiment of the present invention, in which 1 is a guide for a radio R, 2 is a connection socket for the radio, 3 is a fixture for the radio, 4 is a cylinder lock, and 5 is a chassis.

Now, to fix the radio R, align the convex part R1 of the radio with the left and right guide recesses 1A, and turn the knob of the fixture 3 clockwise by 180 degrees. The radio device R is pushed out along the guide recess 1A, and the plug of the radio device R is fitted into the plug seat 2. After that, turn the key of the cylinder lock 4 to lock it.

The structure of the fixture 3 and the cylinder lock 4 are as shown in FIG.

Stopper pin, 21: Rubber, 22: Lock pin, 23: Coil spring, 24: Mounting bracket, 2
5: Cam lock plate, 26: Above the mounting board, 27: Below the mounting board, 28: Knob.

The cam rotation shaft 12 is sandwiched between the upper and lower mounting boards 26 and 27, and the rotation angle is 180° by the stopper 19, stopper pin 20, and slider 14.
It is determined that Turn this cam rotation shaft 12 to the right.
When turned 180 degrees, the slider 14 hanging from the guide rod 13 moves forward by the action of the cam, and slider 1
The push rod 15 fixed to 4 also moves to push the radio R (to the left). A padding rubber 21 is glued to the tip of the push rod 15 to prevent the radio R from being scratched. Due to the shapes of the slider 14 and the cam rotation shaft 12, the rotation of the rotation shaft stops at the maximum amount of movement. Although the lock pin 22 is always separated from the cam rotation shaft 12 by a coil spring 23, the cam lock plate 25 shown in FIG. 2 attached to the cylinder lock 4 shown in FIG. 1 turns the key of the cylinder lock 4. At the same time, the rotation cam pushes the lock pin 22, and the tip of the lock pin 22 is pressed against the cam rotation shaft 1.
It enters the hole provided in 2 to prevent reverse rotation. In other words, the radio is fixed in a locked state.

On the other hand, to release the lock, turn the cylinder lock lock 4 shown in Figure 1 with a key, and then turn the cylinder lock plate 2 shown in Figure 2.
Turn 5. Then the lock pin 22 locks into the coil spring 2.
The cam comes off from the rotating shaft 12 with a force of 3. The cam rotation shaft 12 can now rotate 180 degrees to the left. When the cam rotation shaft 12 is turned to the left, the stopper pin 20 fixed to the cam rotation shaft 12 moves to the stopper 1.
It hits 9 and stops at 180° rotation. The slider 14 and push rod 15 are pushed back toward the cam rotation shaft 12 (to the right) by the force of the coil spring 16. Now there is no longer anything pressing radio R, and the first
It can be removed by pulling it from the plug seat 2 shown in the figure along the concave shape of the left and right guides 1.

The cover 11 in FIG. 2 is fixed with screws from the back side of the chassis 5 in FIG. 1, and the screw heads are not exposed on the surface. The chassis 5 in Figure 1 has a hole for mounting it on a car in the part where the radio R is accommodated, and a third
When the radio R shown in the figure is installed, the screw 30
There is only 1mm from the top of the radio to the bottom of the radio R, so even if you try to disassemble it, no tools will be able to fit in. The guide 1 and plug seat 2 shown in FIG. 1 are also fixed with screws from the inside of the chassis 5 shown in FIG. 1, so that when the radio is installed as shown in FIG. 3, there is no gap in which a tool can fit.

(Effects of the invention) As described above, according to the invention, the push rod of the fixing device positions the radio in its locked state,
The locked state is securely fixed by locking the cylinder lock, and since the chassis is screwed to the vehicle from the inside, the screw heads are completely covered by the radio in the locked state. As a result, theft prevention is reliably achieved.
