Description

[Detailed description of the invention] This invention relates to a motor support device in which a motor is attached to a panel via anti-vibration rubber.In particular, the attachment of anti-vibration rubber to support the motor as a buffer is related to structural improvements. It is.

Conventionally, anti-vibration rubber that cushions the motor is made by forcibly pressing the lower support piece C of anti-vibration rubber B into a through hole provided in panel A against elasticity, as shown in Figure 5. It was installed by fitting the groove into the through hole.

For this reason, it took a considerable amount of effort to attach the vibration isolating rubber B to the panel A, resulting in extremely poor workability.

It is also known that a large-diameter through-hole larger than the diameter of the anti-vibration rubber and a small-diameter through-hole into which the groove of the anti-vibration rubber fits are formed in succession to improve workability. However, there was a drawback that the large diameter through hole was exposed after the anti-vibration rubber was installed.

The present invention has been devised in view of the above-mentioned drawbacks of the conventional art, and will be described below with reference to FIGS. 1 to 4 showing one embodiment of the present invention applied to a motor support device for a record player.

Figure 1 shows the state when the turntable is removed. 1 is a synthetic resin panel, 2 is a support shaft for the turntable (not shown), 3 is a pickup arm, and 4 is a buffer for a motor (described later). It is a vibration-proof rubber that supports the panel 1 and is mounted within the recessed portion 5 formed in the panel 1.

FIG. 2 shows the support structure of the motor, and the concave portion 5 of the panel 1 has a U-shaped notch 7 into which a fitting groove 6 formed in the anti-vibration rubber 4 fits, as shown in FIG. Mounting piece part 8 having
are integrally formed, and a flange portion 9 surrounding the temporary mounting of the vibration isolating rubber 4 is provided facing the mounting piece portion 8 and located below.

The tip of this flange portion 9 and the tip of the mounting piece portion 8 are approximately the same.
The vibration isolating rubber 4 is formed so as to be positioned vertically, and the distance a in the height direction between the mounting piece part 8 and the flange part 9 is
The height dimension a' from the bottom of the fitting groove 6 to the fitting groove 6 is approximately the same.

In FIGS. 2 and 3, 10 is the motor, 11 is the support pin of the motor 10, 12.13 is a washer for attaching the support pin 11 to the anti-vibration rubber 4, and E/IJ song 14 is attached to the anti-vibration rubber 4. The support pin 11 is configured to pass through the formed through hole.

Next, the process of attaching the motor 10 will be explained.

First, the vibration isolating rubber 4 is placed on the flange portion 9, and then the jig 15
is inserted into the through hole 14 of the vibration isolating rubber 40, and the vibration isolating rubber 4 is slid in the direction of the notch 7 formed in the mounting piece 8.

By this sliding, the fitting groove 6 of the vibration isolating rubber 4 is fitted into the mounting piece 8, and the vibration isolating rubber 4 is attached to the panel 1.

Next, attach the support pin 11 of the motor 10 to the through hole 1 of the vibration isolating rubber 4.
4 and a washer 12 and a washer 12 on the protruding end thereof.
All work is completed by installing J7G13.

In the embodiment, the vibration isolating rubber 4 is slid using the jig 15, but the vibration isolating rubber 4 may be held and slid directly by hand.

As is clear from the above embodiments, according to the present invention, the anti-vibration rubber can be easily installed with a simple structure, and after the anti-vibration rubber is installed, the inside of the unit is exposed due to the presence of the flange. It has great practical value, such as being invisible, improving design effects, and improving safety.
