Tighten together with the two buffer members on both sides of the second
The first member is fixed to the first member, and the first member is inserted into the space formed by the fixation, with the first member sandwiched between the two buffer members.

[Industrial application field]

The present invention relates to a structure for attaching a buffer member for fog prevention.

Among electronic devices, the electronic device 1, which is sensitive to shock, is accommodated and transported in a container 2 having a fog-proof structure, as shown in FIG.

The electronic equipment 1 is fixed on the table 3 and mounted on both sides of the table 3 or on brackets 5.6 on the side walls of the container 2 via rubber cushioning members 4.

This buffer member 4 is made of rubber and is difficult to attach because it deforms elastically, but it needs to be firmly fixed so that it will not come off due to the vibrations it receives.

[Conventional technology]

FIG. 5 shows a conventional example.

FIGS. 6 and 7 each show the buffer member IO.

The buffer member IO has flange portions 12a, 13a of flanged bolts 12.13 at both ends of the rubber cylindrical body 11.
It is a structure that is fixed with adhesive.

12b and 13b are bolt parts.

This buffer member IO is mounted on the bracket 5 by screwing two nuts 14 and 15 into the bolt portion 13b passed through the hole 5a of the bracket 5.

The table 3 has the hole 3a screwed into the bolt part 12b,
It is placed on the flange portion 12a. The nut 16 is first screwed onto the bolt portion 12b projecting above the table 3 and tightened, and then the nut 17 is screwed onto the bolt portion 12b to prevent the nut 16 from loosening.

[Problem to be solved by the invention]

When the first nut 16 is tightened, the rubber cylindrical body 11 is twisted, the flange portion 12a is shifted against the table 3, and the resistance to tightening does not increase, making it possible to tighten the nut 16 as much as you like. There is no end to it, and the only way to tighten it is to make it strong enough.

Therefore, if left as is, the nut 16 is likely to loosen due to vibration or the like.

The double nut method that compensates for this requires tightening the nut 17 separately, which is cumbersome.

SUMMARY OF THE INVENTION An object of the present invention is to provide a structure for attaching a buffer member that allows the attachment of a buffer member to be carried out reliably and with good workability.

[Means to solve the problem]

The present invention provides a structure in which a buffer member is attached between the second member and the first member in order to prevent the first member from fogging against the second member, the buffer member being in contact with the second member. The buffer member mounting member is a rigid body that has legs and forms a space between the legs and the second member when the legs are in contact with the second member; A member is fixed to the second member by fastening together with the first member and two buffer members on both sides of the first member, and the two members are fixed in the space formed by the fixing. The structure is such that the first member is inserted between the buffer members.

[Effect]

In the case of mounting the above-mentioned buffer member, the member is a rigid body, and the end of tightening is determined when the member is fixed to the second member. Become.

It has a.

Reference numeral 27 denotes a first cushioning member made of rubber, which is shaped like a rectangular plate with a thickness of t2, and has a hole 27a in the center.

Reference numeral 28 designates an inverted U-shaped buffer member mounting member, which is made of metal, and has a second buffer member made of rubber in the form of a rectangular plate with a thickness of t2 on the bottom side, similar to the first buffer member 27 described above. Member 29 is glued.

For attachment, holes 28a and 29a are formed in the center of the member 28 and the second buffer member 29, respectively.

The mounting member 28 has downwardly extending legs 28b and 28c on both sides of the top plate 28d.

The length E of the second leg portions 28b and 28c is the thickness (t + +2
It is determined to be a dimension a shorter than X t 2 ).

Next, the attachment of the first and second buffer members 27 and 29 will be explained.

First, by tightening the nut 26 toward the lower end using the flange portion 24a through the washer 25, the bolt 24 is fixed to the bracket 5, which is the second member, so as to protrude upward from the bracket 5.

At this time, the bracket 5 is clamped and fixed between the flange portion 24a and the nut 26, and the nuts are tightened as usual and are sufficiently tightened, so there is no need for double nuts.

Next, the first buffer member 27 is inserted into the hole 27a with the bolt 2.

When the nut 31 is tightened, the tongue portion 20 and the first and second buffer members 26 and 29 are tightened together with the mounting member 28, and the mounting member 28 moves downward, and the first and second buffer members 27 .29 is compressed.

When the mounting member 28 is moved down the dimension a, the legs 28b, 2
The lower end 28b-1, 28cm1 of the nut 8c presses against the bracket 5, restricting further downward movement, and the nut 31 is tightened with a sufficiently large torque. Therefore, there is no need to use the double nut method.

FIG. 1 shows the state after the nut 31 has been tightened.

For attachment, a space 35 having a height of l is formed between the top plate portion 28d of the member 28 and the bracket 5.

Also, the installation is performed in accordance with the downward movement of the member 28. The second buffer members 27, 29 are compressively deformed.

Note that the dimension in which the buffer members 27 and 28 are compressed is the leg portion 28b of the clamp member 28 as described above.

This is uniquely determined by the length of 28c, etc., and the tightening of the nut by the worker is not affected by the amount. It is possible to obtain the optimum anti-fog effect.

As a result, the buffer members 27 and 29 are clamped and fixed by the mounting member 28 within the space 35 between the bracket 5 and the mounting member 28, with the tongue portion 20 sandwiched therebetween.
