Abstract

PURPOSE:To protect an assigning number module by using a slide member driven by a screw not turned by a conventional screw driver so as to lock a cover thereby designing the structure in which the cover cannot be opened without a special jig. CONSTITUTION:A slot 6 engaged with a projection 5 provided to an aperture 2 of an enclosure 1 is provided to one end of the cover 3 and a lock piece 8 having a hole 7 engaged with the slide member 4 is provided to the other end. Further, the slide member 4 is formed as L-shape, supported freely slidably between the enclosure 1 and a slide member holding member 13, one end is engaged with the hole of the lock 8 provided to the cover 3 and the tip of the screw 10 is fitted to the other leading part turnably by a C-ring 14 without axial play. Further, the screw 10 is screwed to a nut fixed by the slide member holding member 13 and a screw driver slot 12 engaging with a special screw driver is formed to its head 11.

Description

[Detailed Description of the Invention] [Summary] This is a locking structure for a lid, in which the lid has a groove at one end that engages with the casing in a concave-convex engagement, and the other end that engages with a slide member. A locking piece having a matching hole is provided, and a screw is provided in the casing to enable sliding movement of the slide member, and by rotating the screw, the lid can be locked and opened.

[Industrial application field]

The present invention is a mobile phone assigned number module (
Number Assignment module)
This concerns the locking structure of the lid of the room in which the device is installed.

[Prior Art and Problems to be Solved by the Invention] Conventional telephones do not have such protection for assigned number modules. However, it is necessary that this assigned number module cannot be easily removed by the user.

The present invention was created in view of these points, and an object of the present invention is to provide a lid lock structure that cannot be easily opened.

[Means for solving problems]

Therefore, in the present invention, a removable lid 3 that closes the opening 2 of the housing l, a slide member 4 that locks the lid,
The lid 3 comprises a driving means for driving the sliding member, and the lid 3 is provided with a groove 6 at one end that engages with a protrusion 5 on the edge of the opening 2 of the housing l, and a groove 6 at the other end. is provided with a locking piece 8 having a hole 7 that engages with the slide member 4, and the slide member 4 is configured such that one end thereof can be freely engaged and detached from the hole 7 of the locking piece 8 of the lid 3. The driving means is slidably supported by the housing 1, and has a nut 9 provided on the housing 1 and a screw 10 screwed into the nut, and the tip of the screw is rotatably attached to one end of the slide member 4. The main feature is that the screw can be mounted without play in the axial direction, and that the head 11 of the screw is provided with a special driver groove 12.

[Effect]

By locking the lid with a sliding member driven by a screw that cannot be moved with a normal screwdriver, the assigned number module can be protected by preventing the lid from being opened without special tools.

〔Example〕

FIG. 1 is a sectional view showing an embodiment of the present invention.

In the figure, 1 is the casing of the mobile phone, 2 is the opening, and 3
is a lid, 4 is a slide member, 5 is a protrusion, 6 is a groove, 7 is a hole,
8 is an engagement piece, 9 is a NAND, 10 is a screw, 11 is a screw head, 12 is a driver groove, 13 is a slide member holding member, 14 is a C ring, and 15 is an assigned number module.

As shown in FIG. 1, this embodiment is comprised of an M3 that can be attached to and removed from an opening 2 of a housing 1, a slide member 4, and a slide member drive section. One end of the lid 3 is provided with a groove 6 that engages with a protrusion 5 provided in the opening 2 of the housing 1, and the other end is provided with a hole 7 that engages with a slide member 4. A locking piece 8 is provided. Further, the slide member 4 has an L-shape, is slidably supported between the housing 1 and the slide member holding member 13, and has one end attached to the lid 3.
It can be engaged with the hole 7 of the engagement piece 8 provided on the other side, and the tip of the screw 10 can be rotated by the C-ring 4 on the other rising part, and the screw 10 can be attached without any play in the axial direction. There is. Further, the slide member driving section consists of a nut 9 and a screw 10, and the screw 10 is screwed into the nut 9 fixed by a slide member holding member 13, and has a driver groove 12 in its head 11 that engages with a special screwdriver. It is formed.

FIG. 2 is a diagram showing an example of the driver groove 12 in the head 11 of the screw 10. This has a pin 16 in the center of the hole for a Phillips screwdriver.

In this embodiment configured as described above, when the lid 3 is set in the opening 2 of the housing l and the screw 10 is tightened, the slide member 4 moves forward and engages with the hole 7 of the locking piece 8 of the lid 3. to lock. When trying to open it, use a special screwdriver to remove screw 1.
0 in the counterclockwise direction, the slide member 4 will move back and the lock can be released. In this way, the lid 3 cannot be opened without a special screwdriver. Therefore, it cannot be opened with a regular screwdriver. This makes it possible to prevent tampering and protect the assigned number module.

〔Effect of the invention〕

As described above, according to the present invention, the lid can be locked with an extremely simple structure, which is extremely useful in practice.
