Next, the detachable corner crown portion 4 has a connection support plate 9 having a plurality of mooring holes 13 provided at regular intervals, the mooring holes 13 being moored to locking pieces 7 of a key lever 6 projecting at one end from the bottom surface of the dial lock type lock 2. And a crowned portion 10 connected to the other end of the connection support plate 9 in a T-shape similarly to the fixed corner crowned portion 3 described above. The crowned portion 10 covers the corners of the case in the up-down direction, and is formed by bending a mooring piece 11 for inserting and mooring the connection opening provided in the case.
Further, the shield plate 12 is provided in a state where the connection opening portion does not interfere with the harness connected to the connector in a state of crossing the mooring piece portion 11.
[0021]
Therefore, as shown in FIG. 3, the circuit board storage box 14 has a circuit board 16 mounted on a base 15 and each corner of the case 17 is fastened and fixed to the base 15 by screws.
[0022]
A fixed corner crown portion 3 connected and fixed to the dial lock type lock 2 is attached so as to cover one corner of the case 17, and a detachable corner crown portion 4 is attached to the other corner. The connection support plate 9 is inserted into the bottom surface of the dial lock type lock 2 so as to cover it. At this time, with the auxiliary shielding plate 19 attached to the connection opening 18 formed at the front and rear ends of the case 16, both ends of the auxiliary shielding plate 19 are fixed to the fixed corner crowning portion 3 and the removable corner crowning portion 4. The key lever 6 is operated and locked and connected by the setting portion 10 in a locked state.
[0023]
By further turning the dial 5, the password becomes the erased number and the key lever 6 is locked.
[0024]
In the present invention having the above configuration, since the corners of the case are covered with the crown portions, the screws for fastening the base and the case are completely shielded, and it becomes impossible to remove the screws from the outside. .
[0025]
In addition, when the fixed corner crown portion and the detachable corner crown portion are locked by a dial lock type lock for mooring with the mooring piece inserted into the connection opening of the case. It becomes impossible to remove it from the circuit board storage box.
[0026]
Furthermore, since the connection opening of the case is covered by the shielding plate and the auxiliary shielding plate so as not to hinder the harness, it is possible to prevent the connection opening from being fraudulent.
[0027]
FIG. 4 is a perspective view for explaining another example of the lock device for a circuit board storage box to which the present invention is applied, and FIG. 5 is a side explanatory view in FIG. The lock device main body 1 shown here includes a dial lock type lock 2, a rectangular locking plate 20 which is connected and fixed to the dial lock type lock 2, and a detachable which can be freely connected and fixed to the dial lock type lock 2. And a rectangular locking plate 21.
[0028]
Therefore, the dial lock type lock 2 is provided with four dials 5 each having a number from 0 to 9 attached to the four dials 5.
[0029]
The key lever 6 is unlocked by turning the dial 5 to set the number to the password, and the key lever 6 is locked when the number of the password is erased.
[0030]
Here, the key lever 6 has a halfway portion pivotally supported in the dial lock type lock 2 and a locking piece 7 formed at the lower end thereof. Therefore, by turning the key lever 6 right and left, the locking piece 7 at the lower end is configured to be able to protrude from the bottom surface of the dial lock type lock 2.
[0031]
One end of the rectangular locking plate 17 is connected to and fixed to the bottom surface of the dial lock type lock 2 by a screw 8, and the rectangular locking plate 17 can be locked from the case of the openable / closable circuit board storage box to the bottom of the base. It is bent into a shape.
[0032]
Further, the detachable rectangular locking plate 20 is provided with a plurality of mooring holes 13 at fixed intervals, the mooring holes 13 being moored to the locking pieces 7 of the key lever 6 projecting at one end from the bottom surface of the dial lock type lock 2. Like the stop plate 19, it is bent into a rectangular shape so that it can be locked from the case of the openable / closable circuit board storage box to the bottom surface of the base.
[0033]
Therefore, as shown in FIG. 6, the openable circuit board storage box 14 has a circuit board 16 mounted on a base 15, one end of a case 17 is pivotally supported on the circuit board 16, and the other end is screwed on the other end. Thereby, the base 15 is fastened and fixed.
[0034]
Then, a rectangular locking plate 20 connected and fixed to the dial lock type lock 2 is mounted so as to fit from the case 17 to the bottom surface of the base 15, and a detachable rectangular locking plate 21 is similarly connected to one end of the same. Is inserted into the bottom surface of the dial lock type lock 2 so as to fit over the bottom surface of the base 15 so as to be symmetrical with the rectangular locking plate 20.
[0035]
At this time, with the auxiliary shielding plates 19 attached to the connection openings 18 formed at the front and rear ends of the case 17, these auxiliary shielding plates 19 are fixed to the rectangular locking plate 20 and the detachable rectangular locking The key lever 6 is operated and locked and connected by the plate 21.
[0036]
By further turning the dial 5, the password becomes the erased number and the key lever 6 is locked.
[0037]
In the present invention having the above configuration, the case and the base are locked in such a manner as to be wound by the rectangular locking plate and the detachable rectangular locking plate, so that it is impossible to open the case and perform an illegal operation. Become.
[0038]
Further, the connection opening of the case is covered by the auxiliary shielding plate so as not to hinder the harness, so that illegality from the connection opening becomes impossible.
[0039]
Here, the dial of the dial lock type lock does not necessarily need to be formed by four, and may be three or two as long as the lock cannot be easily released. In addition, it is preferable to adopt a configuration in which a password setting function is provided on the dial lock type lock so that the password can be changed periodically.
[0040]
Further, the fixed corner mounting portion and the detachable corner mounting portion, the rectangular locking plate, and the removable rectangular locking plate are configured to be compatible with a circuit board storage box corresponding to various pachinko / slot machines. Things.
