Description

TECHNICAL FIELD The present invention relates to a mounting structure for an instrument mounted on an automobile, a motorcycle, or the like.

[Prior Art and Problems Thereof] Conventionally, as this type of mounting structure, for example, one shown in FIG. 5 is known. That is, the bracket 102 formed by deep drawing is welded to the lower surface of the mounting plate 100, the bolt 106 is welded to the lower surface of the instrument 104, and the nut 108 and the elastic members 110, 1 are provided.
12 is used to fix the instrument 104 to the bracket 102.

However, in this conventional technique, the deep-drawn bracket 102, the bolt 106, the nut 108, and the elastic members 110 and 112 are used.
However, there is a problem that not only the structure is complicated because many parts such as the above are required, but also the workability is not good because the welding work is required. Further, in order to firmly attach the measuring instrument 104 to the mounting plate 100, it is necessary to use the bracket 102 and a large number of parts to form a rigid structure as described above, but this allows vibration from the mounting plate 100 to be transmitted to the measuring instrument 104. It will be easier. On the contrary, when the vibration-proof property is emphasized and the flexible structure is adopted, the disengagement and rattling of the instrument 104 become a problem, and therefore both the firm mountability and the vibration-proof property are not sufficiently satisfied.

Also, instrument mounting structures such as Japanese Utility Model Publication No. 55-42307, Japanese Utility Model Publication 55-42461, and Japanese Utility Model Publication No. 55-117920 are known, but still have a solid structure and anti-vibration property. It is not a combination of.

The present invention aims to solve the above-mentioned problems of the conventional technique, and by devising the structure of the elastic support member for attaching the instrument to the mounting plate, the instrument can be firmly attached to the attaching plate with one touch. , It is an object of the present invention to provide a mounting structure for a meter, which has improved vibration proofing properties for the meter.

[Means for Solving the Problems] The measuring instrument mounting structure according to the present invention, which has been made to solve the above-mentioned problems, has an elastic supporting member mounted in a mounting hole formed in a mounting plate, and the measuring instrument is mounted through this supporting member. In the mounting structure of the instrument having attached, the elastic support member is formed with a holding hole into which the main body of the instrument having a collar portion formed at an upper portion thereof can be inserted with a predetermined gap and is attached to the mounting hole. It consists of a collar and a leg projecting from one end of the collar to the side wall of the instrument at a predetermined distance.The lower end of the leg is inclined toward the instrument and has elastic force. Forms a tongue that clamps the instrument over almost the entire circumference, and the side part of the instrument has a protruding part that restricts the movement of the instrument in the detaching direction when it touches the tongue. In addition, the restriction part is formed with an outer diameter that allows the holding hole to be inserted. Together, restricting portion is characterized in that it is possible to form passing through the tongue and expanded by elastically deforming the tongues.

[Operation] In the configuration of the present invention, the elastic support member is mounted in the mounting hole formed in the mounting plate, and the instrument is mounted via the elastic support member. The elastic support member is fitted in the mounting hole. A leg portion is provided so as to project from one end of the flange portion held together to the side wall of the instrument with a gap, and the lower end of the leg portion is a tongue portion inclined to the instrument side.

When mounting the instrument, the tongue with such a structure is elastically deformed and expanded by the restricting part that has passed through the holding hole, and the restricting part passes through the tongue, so just push the meter in with one touch. It has an action of holding the instrument by elastic force, firmly holding almost the entire circumference of the instrument in a clamped state, and abutting against the regulating portion of the instrument to regulate the falling of the instrument.

Furthermore, since there is a gap between the leg and the instrument, and the instrument is held only by the tongue, the vibration of the mounting plate, etc. is buffered and does not transmit strongly to the instrument. Is also excellent.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a cross-sectional view showing a mounting state of the instrument, and FIG. 2 is an exploded perspective view. In FIG. 1, 1 is a mounting plate having a circular mounting hole 3, and the mounting plate 1 has an elastic support. An instrument 7 is attached via the member 5. The instrument 7 is a speedometer or the like used in a two-wheeled vehicle, and includes a display portion 11 having a collar portion 9 on the upper portion thereof, and a main body portion 15 in which a mechanism portion for driving the display portion 11 is housed in a case 13. , Case 13
On the side wall of the, the inclined projections 17 having four step portions 17a are formed at equal intervals in the circumferential direction.

Further, the elastic supporting member 5 is made of rubber, and has a collar portion 21 in which an annular groove 19 is formed on the outer peripheral portion and a holding hole 20 is formed on the inner portion, and one end of the collar portion 21 extends from the casing 21 to the case of the instrument 7. 13 includes a leg portion 23 projecting toward the side wall. The lower end of the leg portion 23 has an instrument 7
The tongue portion 25 is formed to have a thin thickness while inclining toward. The inner diameter of the tip of the tongue portion 25 is set to be slightly smaller than the outer diameter of the case 13 when the measuring instrument 7 is not attached. The dimensions of each member are such that a gap t is formed between the holding hole 20 and the case 13 and a minute gap s (about 0.5 mm) is formed between the tip of the tongue portion 25 and the step portion 17a. Is set.

In the above configuration, when the instrument 7 is attached, first, the elastic support member 5 is attached to the attachment plate 1 by fitting the annular groove 19 of the elastic support member 5 into the attachment hole 3 of the attachment plate 1. Next, the instrument 7 is pushed into the holding hole 20 of the elastic support member 5 in the arrow direction. At this time, the tongue portion 25 at the tip of the elastic support member 5 is expanded by the side wall of the case 13 so that the tongue portion 25 is inclined.
Push it to the position where you got over the top edge of the. As a result, the tongue portion 25 clamps the instrument 7 by the elastic force at the position where the tongue portion 25 has the minute gap s with respect to the step portion 17a.

Therefore, the instrument 7 can be reliably held by the tongue portion 25 of the leg portion 23 by one-touch work of pushing it into the holding hole 20 of the mounting plate 1, which is excellent in workability.

Further, since the elastic support member 5 is made of rubber and has the gap t on the wall surface of the holding hole 20 of the collar portion 9 and the instrument 7 does not come into direct contact with the elastic support member 5, the vibration generated in the mounting plate 1 or the like passes through this. A slightly thin tongue 25 that cannot be transmitted to the instrument 7.
It is only conveyed by. Therefore, the elastic support member 5 has an excellent cushioning action against the vibration generated in the mounting plate 1. Moreover, even if a force is applied to the measuring instrument 7 in the detaching direction, the tip of the tongue portion 25 comes into contact with the stepped portion 17a to perform a retaining action, so that the measuring instrument is firmly held. Moreover, since the tip of the tongue portion 25 has a minute gap s with respect to the step portion 17a, it has a damper action against vibration.

Further, as a part to which the instrument 7 is attached, the elastic support member 5
It is sufficient, and parts such as bolts and nuts are not required, so the configuration is simple.

Furthermore, unlike the prior art, since there is no protruding portion such as a bolt or a nut on the outer peripheral portion of the instrument 7, it does not hinder the attachment of other components.

In addition, in the above embodiment, the restricting portion provided on the case is realized by the inclined projection 17, but the same effect can be obtained by the annular groove 31 formed on the side wall of the case 13 as shown in FIG. .

As a modified example of the elastic support member, as shown in FIG. 4, a slit 41 is provided from the lower end of the tongue portion 25, or
By forming the through hole 43, the tongue portion 25 of the elastic support member 50 may be easily opened to facilitate the attachment.

The device to which the present embodiment is applied is not limited to a vehicle, but is particularly suitable for a place where vibration is generated, such as a machine tool.

[Effects of the Invention] As described above, according to the present invention, by devising the structure of the elastic member for attaching the instrument to the mounting plate, the instrument can be attached by one-touch work of pushing the instrument into the holding hole. It can be easily attached to a plate, and since the instrument is pushed in from the front side, it is very easy to work with, and it also has an excellent effect of buffering vibration to the instrument.
