蔽具が既に提案されている。[0002] When paint particles enter the threads and solidify, it becomes difficult or impossible to screw in the bolts, so it is necessary to close the bolt holes prior to the painting process. For this purpose, a soft plastic with a tapered tip at the side of insertion into the bolt hole, an enlarged flange at the base for finger hooking at the time of extraction, and at least one of the tip and the base closed. A bolt hole shielding device made of a cylindrical body has already been proposed.

た。When this shield is inserted into a bolt hole, its outer peripheral surface is held in the initial insertion position by being tightly and elastically engaged with a screw thread. There are tolerances during processing and molding, and when these errors work in addition, the fixing force of the closing tool to the bolt hole becomes weak, it falls off in the middle, and paint particles enter from the gap There were things.

具を提供することである。SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to absorb a dimensional error existing in a bolt hole diameter or an outer diameter of a cylindrical body, and to insert the bolt hole into the bolt hole with a sufficient fixing force.
An object of the present invention is to provide a paint bolt hole shield capable of accurately preventing paint particles from entering.

る。Means for Solving the Problems Hereinafter, a description will be given using reference numerals in the accompanying drawings. The coating bolt hole shielding tool 2 of the present invention has a tapered tip 2a on the side to be inserted into the bolt hole 1. , A finger hook 3 at the time of extraction from the base end 2b
A cylindrical body having at least one of a distal end portion 2a and a proximal end portion 2b closed, and a plurality of linear projections 4 arranged on an outer surface of the cylindrical body at predetermined circumferential intervals. Is provided.

体５の前面に近接する位置まで押し込まれる。In use, the bolt hole shield 2 is inserted into the bolt hole 1 of the object 5 to be painted from the tapered tip 2a. The operation of inserting the distal end portion 2a is smoothly performed, but after this, the linear projection 4 receives resistance. By applying a propulsive force that overcomes the resistance from the base end portion 2b, the bolt hole shield 2 is pushed to a position where the finger hook flange 3 comes close to the front surface of the object 5.

ト孔１のねじ山尖端に密着することになる。In this pushing process, the excessive projecting portion of the linear projection 4 is scraped or crushed by the thread edge of the bolt hole 1, and the bolt hole shielding device 2 is almost the entire length of the portion inserted into the bolt hole 1. And it comes into close contact with the thread crest of the bolt hole 1 on the entire circumference.

よって、ボルト孔１から引き抜かれる。As a result, even if the paint particles are sprayed from any direction before or after the object 5, the paint particles do not enter the bolt holes 1. After the completion of the painting process, the bolt hole shield 2 is pulled out from the bolt hole 1 by hanging a fingertip on the finger hook flange 3 of the base end 2b.

Two linear projections are formed at an interval of 180 degrees. The bolt hole shield 2 is closed at the base end 2 b side, and the closed wall portion is formed continuously with the finger hook flange 3.

た、塗料粒子の侵入を確実に阻止することができる。As described above, in the bolt hole shielding tool 2 of the present invention, a plurality of linear projections 4 are provided on the outer surface of the cylindrical body at predetermined intervals in the circumferential direction and are provided in the axial direction. Since the linear projection 4 is crushed or scraped off at the tip of the thread of the bolt hole 1 in the process of being pushed into the bolt 1, the dimensional errors existing in the bolt hole diameter and the cylinder outer diameter are accurately absorbed.
It can be inserted into the bolt hole 1 with a sufficient fixing force, and the penetration of paint particles can be reliably prevented.
