Abstract

The utility model provides a dustproof rubber plug for an inner hexagonal cylindrical head bolt, which comprises a plug head matched with an inner hexagonal hole of a screw cap, wherein a dustproof cap is arranged at the top of the plug head and is connected with a hand grip through a soft connecting sheet. The dustproof rubber plug can protect the hexagon socket at the top of the nut and is easy to disassemble and assemble.

Description

Dustproof rubber plug for inner hexagonal cylindrical head bolt

Technical Field

The utility model belongs to the field of power station connecting pieces, and particularly relates to a dustproof rubber plug for an inner hexagonal cylinder head bolt.

Background

The water baffles are installed on the left and right banks of the household dam power station, the stand columns of the water baffles are connected with the base plates which are embedded on the ground through the inner hexagonal cylindrical head bolts, and flood can be effectively prevented from entering a factory building after the water baffles are installed. The inner hexagonal socket head bolt is directly installed on a backing plate on the ground at ordinary times, and dust can be prevented from entering the bolt hole. However, the top of the inner hexagon socket head cap screw is not protected, and after the inner hexagon socket head cap screw is blocked by dust, the installation of the water baffle plate is influenced.

Disclosure of Invention

The utility model aims to solve the technical problem of providing a dustproof rubber plug for an inner hexagonal socket head bolt, which can protect an inner hexagonal hole at the top of a nut and is easy to disassemble and assemble.

In order to solve the technical problems, the technical scheme adopted by the utility model is as follows: the utility model provides a dustproof plug for hexagon socket head cap screw bolt, includes the chock plug with the interior hexagonal hole adaptation of nut, and the chock plug top is equipped with dustproof cap, and dustproof cap passes through soft connection piece and connects the tongs.

In a preferred scheme, the hand grip is of an annular structure.

In the preferred scheme, the plug, the dustproof cap, the soft connecting sheet and the hand grip are made of rubber or silica gel.

In the preferred scheme, including the connecting pad, the connecting pad sets up the downside at the nut, is equipped with the through-hole with the screw rod adaptation on the connecting pad, and the connecting pad passes through soft connecting portion and is connected with the tongs.

According to the dustproof rubber plug for the hexagon socket head cap bolt, the hexagon socket hole is plugged through the plug head, the connection with the nut is realized, and the dustproof cap covers the upper side of the hexagon socket hole and further shields the hexagon socket hole. Connect the tongs through soft connection piece, can realize taking out dustproof plug through mentioning the tongs, simultaneously when need not take out, soft connection piece and tongs and dustproof cap lie in the coplanar, prevent to cause the plug to break away from interior hexagonal hole behind the hook to the tongs.

Drawings

The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:

FIG. 1 is a schematic view of the mounting structure of the present invention;

FIG. 2 is a bottom view of the present invention;

FIG. 3 is a schematic view of a preferred mounting arrangement;

in the figure: nut 1, screw rod 2, interior hexagonal hole 3, chock plug 4, dust cap 5, soft connection piece 6, tongs 7, connection pad 8, soft connecting portion 9.

Detailed Description

As shown in fig. 1-2, a dustproof plug for hexagon socket head cap bolt, include the chock plug 4 with 3 adaptations of hexagon socket head cap hole of

nut

1, 4 tops of chock plugs are equipped with dustproof cap 5, and the size of dustproof cap 5 is greater than the size of chock plug 4, realizes the cover to hexagon socket head cap hole 3, and dustproof cap 5 passes through soft connection piece 6 and connects tongs 7, and in this embodiment, the quantity of soft connection piece 6 is two, sets up along the central line symmetry of nut 1.

The hand grip 7 is of an annular structure. Set up tongs 7 into annular structure, be favorable to improving tongs 7's intensity.

The plug 4, the dustproof cap 5, the soft connecting sheet 6 and the hand grip 7 are made of rubber or silica gel.

During the specific use, when needs dismouting hexagon socket head cap screw, mention tongs 7, lift cock 4, separate with hexagon socket head cap 3, can carry out operation on next step.

Carry out the shutoff through chock plug 4 to interior hexagonal hole 3 to realize being connected with nut 1, dustproof cap 5 covers including 3 upside of hexagonal hole, carries out further shelters from.

Connect tongs 7 through soft connection piece 6, can realize taking out dustproof plug through mentioning tongs 7, when need not take out simultaneously, soft connection piece 6 and tongs 7 are located the coplanar with dustproof cap 5, prevent to cause the plug to break away from behind the tongs 7 hook.

Preferably, as shown in fig. 3, the nut includes a connection pad 8, the connection pad 8 is disposed at a lower side of the nut 1, a through hole adapted to the screw rod 2 is disposed on the connection pad 8, and the connection pad 8 is connected to the gripper 7 through a flexible connection portion 9.

The connection of the connecting gasket 8 and the hand grip 7 is realized through the soft connecting part 9, and the rubber plug can be prevented from being lost because the soft connecting part 9 is pressed on the lower side of the screw cap 1.
