Description

[Detailed Description of the Invention] The present invention relates to a locking mechanism for a wall-mounted casing provided primarily as a countermeasure against eavesdropping in CATV terminal equipment.

Locking the housing cover has already been proposed in various ways for the purpose of protecting the inside of the housing from third parties, especially malicious persons who attempt to spy on the inside of the housing.

However, for CATV terminals that are normally structured to be fixed to a wall, firmly mounting them on the wall with appropriate fixing means and locking the case cover to prevent unauthorized opening are independent of each other. Therefore, even if the key lock mechanism cannot be unlocked, if the locking means is forcibly released, the interior may be manipulated relatively easily.

The present invention was developed to improve the above-mentioned drawbacks.The casing structure is divided into two parts, and when the casing cover is on, the fixing means to the wall cannot be touched, and the casing can be locked. The present invention aims to provide a locking mechanism for a wall-mounted case configured so that the cover cannot be removed.

For this purpose, the present invention has a case in which the base of the case is mounted on a wall surface, a case cover is attached to the base, and the case is locked, the base has a bracket structure having a wall surface mounting part and a bottom surface mounting part, The key box is provided with a key box into which a key is inserted from the bottom and locked, and a hook is provided in the wall mounting part, and the case cover is attached to the base from above while engaging with the hook, and the key is enclosed. The present invention is characterized in that a lock claw engages with the housing cover when operated, thereby prohibiting removal.

Hereinafter, one embodiment of the present invention will be specifically described with reference to the drawings. In the figure, reference numeral 1 denotes an L-shaped housing base having a base wall attachment portion 1a and a base bottom attachment portion 1b, and has a bracket structure. The housing base 1 has a key box 2 mounted on its bottom mounting portion, and is provided with a key hole (not shown) on the lower surface of the bottom mounting portion.
By inserting the key 3 from there and locking the lock, the lock pawl 2a can be rotated horizontally.

In addition, ribs 1c are provided on both sides of the wall mounting part.
is upright, and an upward L-shaped hook 4 is integrally formed therein, and the wall mounting part 1a itself is equipped with a screw mounting hole 1d, and the wall mounting part 1a is equipped with a screw 5 to attach it to the wall. mounted on.

On the other hand, the housing cover 6 attached to the housing base 1 has an engagement hole 6a into which the hook 4 is inserted and a key box 2 on the bottom and back surfaces, respectively.
For example, a CATV terminal device is built into the housing cover 6. The mounting screws of the housing cover 6 cannot be disassembled unless the back surface or bottom surface is removed.

In such a configuration, for the housing base 1,
By sliding the housing cover 6 from top to bottom with the hook 4 engaged with the engagement hole 6a, the hook 4 is engaged with the upper edge of the engagement hole 6a, and the key box 2 is engaged at the same time. It can be inserted into the matching hole 6b. The housing cover 6 attached in this way is
Locking with the key 3 engages the lock claw 2a with the edge of the bottom panel, preventing it from being pulled upwards, making it impossible to remove it.

As detailed above, the present invention, for example,
By adopting the wall-mounted structure of devices such as CATV terminal devices that are at risk of being viewed internally by internal operations, it is possible to prevent unauthorized opening of the case by preventing the internal structure from being touched other than by officially releasing the lock. Practical effects can be obtained.
