The lock A normally used in automobiles is as shown in Figure 7, in which a square keyhole B is provided in the center of the front surface, and the keyhole B is secured by a square plate C that is biased by the force of a built-in spring. It is always blocked, and when in use, the square plate C is opened and locked or unlocked by inserting the key into the keyhole B, but when a car is parked, it is tampered with and the keyhole B gets stuck. If an object such as a board or a board is forced into the lock, the lock will become unusable.
Furthermore, it had the disadvantage of being easily destroyed.

The purpose of the present invention is to provide a device that effectively protects a lock from such mischief.The front surface of the lock body is covered with a non-magnetic case, and a key corresponding to the keyhole of the lock body is attached to the case. In addition to opening an insertion hole, a shutter plate for opening and closing the key insertion hole is rotatably arranged inside the case, and a magnetic key for opening and closing the shutter plate from the outside of the case. It is characterized by the fact that magnets are provided so that different poles face each other.

In the present invention constructed in this manner, when the magnetic key is brought into close contact with the case from the outside and the different polarities of the magnets provided at opposing parts of the shutter plate match and attract each other, the magnetic key The key insertion hole in the case can be opened and closed by moving the shutter plate, so when the key insertion hole is closed with the shutter plate, the key hole is completely hidden, and unless a special magnetic key is used, the key insertion hole cannot be closed. Since the lock cannot be opened, it is impossible to play tricks on the lock, and destruction of the lock is effectively prevented.

Hereinafter, one embodiment of the present invention will be described based on the drawings. In FIGS. 1 and 2, 1 is a lock A.
It is a case that covers the front side of the lock A, and is made of non-magnetic material (aluminum, stainless steel, brass, etc.) in the shape of a truncated cone, and the flange part 2 at the bottom is attached to the lock A side using instant adhesive. It can be easily attached by adhering and fixing it to a part, for example, the automobile body 3. At this time, the center 0 1 of the case 1 is fixed eccentrically so as to be spaced l 1 from the center 0 2 of the lock A, and the front surface 4 of the case 1 is fixed coaxially to the center 0 2 and approximately l 1 from the center 0 2 of the lock A. A key insertion hole 5 of the same size is correspondingly opened, and a guide groove 6 is recessed in the front surface 4 coaxially with the center 0 1 and having a radius of eccentricity l 1 between the centers 0 1 and 0 2 . It is formed as follows. Inside this case 1, a shutter plate 7 consisting of a rotating plate having approximately the same area as the case front 4 is held freely rotatable, and the above-mentioned eccentricity l 1 is placed from the center of rotation of this shutter plate 7. A through hole 8 of the same size as the key insertion hole 5 is provided at this location, so that when the shutter plate 7 is rotated, the hole 5 is opened only when the through hole 8 overlaps the key insertion hole 5. . In addition, at two locations sandwiching the rotation center 0 1 of the shutter plate 7, and at two locations sandwiching the rotation center 0 1 of the shutter plate 7,
Magnets 9, 9 are buried at positions spaced apart from the center by an eccentricity l1 . Figure 5 shows the shutter plate 7 from outside the case.
shows a magnetic key 10 for rotating the
This key has a T-shaped bar 12 fixed to the tip of the knob 11, and this bar 12
Magnets 13, 13 are attached at the same interval as the magnets 9, 9 (twice l1 ).

In the case configured in this way, the case front 4
Since the key insertion hole 5 is closed by the shutter plate 7 and the lock A inside is not visible, the user cannot even know that the lock A exists, so it is impossible to play tricks on the lock A. However, the user uses the magnetic key 10.
When the magnets 13, 13 of the case are fitted into the guide grooves 6 on the front surface 4 of the case as shown in FIG. 13, 13 and the magnet 9 on the shutter plate 7 side.
The 9 different kindred spirits will match each other and attract each other. However, the magnetic key 10 and shutter plate 7
Since the case 1 located between the two is made of a non-magnetic material as described above, it does not interfere with the attraction of the two magnets 13 and 9 by the magnets 13 and 9. The shutter plate 7 also rotates, and the shutter plate 7
When the through hole 8 overlaps the key insertion hole 5, the hole 5 is opened (FIG. 1 shows this open state). Therefore, after inserting the specified key into the lock A through the key insertion hole 5 and locking or unlocking, the shutter plate 7 is closed again using the magnetic key 10.
Perform the rotation operation to close the key insertion hole 5.

The present invention has been described above, and as is clear from the above embodiments, the intended purpose can be suitably achieved, and the key insertion hole of the lock body is closed unless a special dedicated magnetic key is used. This has the excellent effect of eliminating the negative effects of unauthorized unlocking and preventing damage to the lock due to mischief. This protection device can also be used with ordinary locks used on ordinary doors.
