Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure for attaching a dial plate and a transparent plate to an instrument case in an instrument such as a combination meter for an automobile.

FIG. 1 shows a conventional example of attaching a facing plate to an instrument case, in which a locking claw 2 integrally formed on the facing plate 1 passes through a through hole 4 formed in an instrument case 3 and is attached to an outer part 5 of the instrument case. It has a locking structure.

Further, according to the conventional example, the attachment of the transparent plate 6 disposed in front of the facing plate 1 to the instrument case 3 is the same as the locking structure of the facing plate described above, but as shown in FIG. The outer locking position 8 of the locking claw 7 to the instrument case 3 is located at the outer locking position 8 of the locking claw 2 on the facing plate.
It is slightly shifted from the outer locking position 5.

However, in such a conventional locking structure of the facing plate 1 and the transparent plate 6 to the instrument case 3, the locking claws 2 and 7 are simply locked to the outer parts 5 and 8 of the instrument case 3. Since these locking claws 2 and 7 are exposed to the outside of the instrument case 3, they are easily subjected to some external force, and if external force is applied, these locking claws will easily come off from the instrument case 3. In particular, if the locking claws 2 of the facing plate 1 come off, the transparent plate 6 must be removed from the instrument case 3 and the locking claws of the facing plate must be locked to the instrument case again, which is inconvenient. It was hot.

The present invention was made in order to eliminate such conventional inconveniences, and includes a protective wall that prevents the locking claws of the instrument's face plate and/or transparent plate from receiving external forces from outside the instrument. By providing such a protective wall, it is possible to prevent the locking claws of the facing plate and/or transparent plate from easily coming off from the instrument case due to external force.

An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 3 shows an example in which the present invention is applied when attaching a dial of an instrument to an instrument case, and corresponds to FIG. 1 showing a conventional example.

In FIG. 3, the facing plate 1 has an integrally formed locking claw 2 similar to the conventional example, and this locking claw passes through a through hole 4 formed in the instrument case 3 to extend to the outside of the instrument case. However, according to the present invention, the locking claw 2 of the facing plate 1 is secured to the outside portion 5 of the instrument case 3 to which the locking claw 2 is locked, to protect the locking claw 2 from external force. A protective wall 9 is integrally formed.

By providing such a protective wall 9 on the instrument case 3, the locking claws 2 of the dial plate 1 will not be directly subjected to external force, and therefore the dial plate 1 will not easily come off from the meter case 3 due to external force. Definitely prevented.

In addition, such a protective wall 9 can be used not only in the outer portion 5 of the instrument case 3 where the locking claw 2 of the facing plate 1 is locked, but also in the instrument case 3 where the locking claw 7 of the transparent plate 6 is locked. It is also possible to provide the locking claw 7 of the transparent plate 6 on the outer part 8 (see Figure 2) of the transparent plate 6 to similarly protect it from external forces and prevent it from easily coming off from the instrument case, or if necessary, either It can also be provided on one side.

As described above, according to the present invention, there is provided a structure for attaching a dial plate and a transparent plate to an instrument case in an instrument, which is extremely useful in industry and is protected from external forces and does not easily come off.
