Description

[Detailed description of the invention] The present invention relates to a meter cover assembly mechanism, and more specifically, the meter cover is engaged with the main body by a locking claw, and the outer surface of the locking claw is pressed by the side wall of the back cover. The present invention relates to a meter cover assembly mechanism that prevents deformation of the locking pawl and securely locks the meter cover so that it does not fall off from the main body due to impact, etc. when dropped.

Conventionally, transparent meter covers that cover the instrument panels of various measuring instruments such as testers are screwed to appropriate positions on the main body at their periphery, or fixed using adhesives or the like.

However, when fixing with screws, there are problems such as not only the number of parts increases, but also the time required for assembly.Furthermore, when using adhesives, the fixation is not strong and there is a risk of impact if the main body is dropped. There are problems such as sticking, peeling, and falling off.

The present invention has been developed to solve the above-mentioned problems, and its purpose is to fix the meter cover securely with one touch, and to fix it on the side edge of the meter cover and the tip of the meter cover in various instruments where the upper part of the instrument panel is covered with a transparent meter cover. A support arm having a claw is provided, and the locking claw of the support arm is engaged with an appropriate member to cover the instrument panel and fix the meter cover, and at the same time, the back cover is fitted to cover the internal mechanism of the instrument and is fixed. To provide a meter cover assembling mechanism in which a side wall is inserted into a side opposite to the locking claw of the support arm.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

10 is a tester, 12 is its front cover, 14
is the back cover.

The front cover 12 is mutually fixed to the internal mechanism 20 of the tester 10 via the rotation shaft 18 of the operating knob 16 by appropriately tightening screws or the like.

The back cover 14 covers the back side of the internal mechanism 20 and is fitted to the front cover 12 by having its side wall 22 fitted into the inner surface of the side wall 24 of the front cover 12, and is connected to the internal mechanism 20 with appropriate screws or the like. Fixed.

Reference numeral 26 denotes a meter cover, which is made of a transparent synthetic resin plate and is fitted into a recess 30 provided in the front cover 12 and covers an instrument panel 32 fixed to the upper surface of the bottom 28 of the recess 30.

Reference numeral 34 denotes a support arm, which is protruded from the side edge of the meter cover 26 and inserted through a through hole 29 provided in the bottom 28, and has a locking claw 3 at its tip that locks onto the lower surface of the bottom 28.
6 is provided. The inner surface of the side wall 22 of the back cover 14 contacts the outer surface of the support arm 34 to prevent the support arm 34 from opening outward.

That is, in the present invention, by first pushing the meter cover 26 into the recess 3 of the front cover 12 with the back cover 14 removed, the locking pawl 36 comes into contact with the side edge of the through hole 29 in the bottom part 28. Upon contact, the support arm 34 is elastically opened outward, and by further pressing, the locking pawl 36 locks on the lower surface of the bottom portion 28, thereby preventing it from coming out.

Next, the back cover 14 is attached, but when this is done, the upper edge of the side wall 22 of the back cover 14 enters the space between the outer surface of the support arm 34 and the inner surface of the side wall 24 of the front cover 12, and the support arm 34 from elastically opening into the space. Although the above embodiment has been explained using a tester as an example, it goes without saying that it can be applied to other instruments.

As described above, according to the present invention, when the back cover is attached, the side wall of the back cover presses the support arm and prevents the support arm from opening in the opposite direction of the locking claw. The meter cover will not come off at all even if there is a shock caused by dropping the meter. Furthermore, the meter cover can be easily assembled with one touch, which has many practical advantages.

Although various preferred embodiments of the present invention have been explained above, it goes without saying that the present invention is not limited to each of the above-mentioned embodiments, and may be modified within the scope of the spirit of the invention. It goes without saying that the following modifications can be made.
