Description

[Detailed Description of the Invention] This invention relates to a holding cap for preventing nuts from falling, which are used when working at heights on utility poles, construction, etc.

For example, in power distribution work on utility poles, a large number of horizontal arms, vertical arms, mounting frames, etc. are tightened and assembled using steel bolts and nuts. ,
It is mandatory to tie it to a string. However, nuts are small items, and if a string is passed through a screw hole and tied, it cannot be attached to a bolt, so nuts taken out of tool bags were screwed directly onto bolts. Therefore, they are often accidentally dropped during screwing work, which is dangerous for workers working below and passersby, and accidents have actually occurred.

This invention was made in view of the above-mentioned circumstances, and will be explained with reference to the drawings shown as an embodiment thereof. Reference numeral 1 denotes a holding cap, and the inner diameter surface 3 is connected to the nut 2.
A magnet 6 is built into the inner bottom surface 5 of the recessed portion 4, and a holed ear 8 is provided on the outer bottom surface 7 of the cap. It is provided so that it can be worn.

As shown in the figure, the magnet 6 effectively utilizes magnetic lines of force,
In order to firmly adsorb the nut, it may have a structure in which it is connected to an iron plate 10 whose tip protrudes from the inner bottom surface.

The fall prevention string 9 is tied at its base end to an automatic winder 11, and FIG. 4 shows the string 9 in a pulled out state, from which it is automatically retracted.

12 is a tool bag for electricians.

This idea is as described above, so, for example, on a utility pole, attach the holding cap 1 to the nut 2 in a tool bag, then hold the holding cap and move it to the installation location, and then attach the nut 2 together with the holding cap 1. Rotate and screw onto a bolt (not shown). When the nut 2 is screwed together, the holding cap 1 is pulled to remove it from the nut 2.

As mentioned above, in the past, it was possible for a nut taken out of a tool bag to be accidentally dropped during the short time it was being screwed into a bolt, but with this invention, the nut is fitted into the holding cap inside the tool bag. Therefore, there is no risk of it falling at that time, and the holding cap will stick to it while it is being moved from the tool bag to the installation location, so even if the holding cap is dropped, there is no risk of it falling. Since the string is tied, it supports it, and especially when the string is connected to an automatic winder, the fall prevention string is always organized and does not get in the way of other work, and it also prevents accidental Even when the holding cap is dropped, there is little impact and the nut will not fall off from the supporting cap.

In addition, since the inner surface of the retaining cap is shaped to fit the nut, the nut can be turned by supporting and rotating the retaining cap by hand, and the nut can be screwed onto the bolt with the retaining cap attached. After the nut is completely screwed into the bolt, the retaining cap can be removed and there is no danger of the nut falling.

Therefore, in high-place work, it is possible to completely prevent the accident of dropping a nut when screwing it into a bolt, and work safety can be ensured.
