Disclosure of Invention

The utility model mainly aims to provide a high-rigidity carbon steel hexagonal nut, which can prevent the problem of the integral structure caused by the fact that other people screw the nut by mistake, and can effectively solve the problem in the background technology by utilizing the high rigidity property of carbon steel to further protect the integral structure from being damaged.

In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

the high-rigidity carbon steel hexagonal nut comprises a hexagonal protective shell and is characterized in that a through hole is formed in the center of the hexagonal protective shell, an inner groove for providing a clamping and fixing space is formed in the center of the through hole between the inner parts of the hexagonal protective shell, a screw body is inserted in the through hole in a penetrating manner, and a clamping positioning piece is fixedly connected to the center of the outer side wall of the screw body; the screw body center department link up and has offered the screw groove, separates through screw body and hexagonal protective housing and is connected so that after the nut is wholly fixed, can prevent that other people from turning on the nut by mistake from leading to the condition that the overall structure goes wrong to and utilize the high rigidity performance of carbon steel and then protect overall structure not destroyed.

Further, the connection part of the screw body and the through hole is connected in a rotating mode through a rotating shaft, and the screw body cannot be screwed by screwing the hexagonal protective shell under the unclamped state through the rotating shaft.

Further, the side wall of one side of the screw body is provided with a plug hole, and the fixing clamping piece is inserted through the plug hole.

Further, a fixing clamping piece for enabling the clamping positioning piece to be fixed is inserted into the plug hole, and the clamping positioning piece is clamped through the fixing clamping piece, so that the nut is screwed.

Further, the clamping positioning piece rotates in the inner groove, the height and the width of the clamping connecting piece are slightly smaller than those of the inner groove, and the clamping positioning piece slightly smaller than the inner groove space is used for preventing mechanical abrasion from affecting use.

Compared with the prior art, the utility model has the following beneficial effects:

the nut is connected with the hexagonal protective shell through the screw body, so that after the nut is integrally fixed, the condition that the nut is unauthorised screwed by other people to cause problems of the integral structure can be prevented, and the high rigidity performance of carbon steel is utilized to further protect the integral structure from being damaged, so that the problems are solved.

Detailed Description

The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.

As shown in fig. 1-3, the high-rigidity carbon steel hexagonal nut comprises a hexagonal protective shell 1, and is characterized in that a through hole 3 is formed in the center of the hexagonal protective shell 1, an inner groove 4 for providing a clamping and fixing space is formed in the center of the through hole 3 between the inner parts of the hexagonal protective shell 1, a screw body 2 is inserted in the through hole 3 in a penetrating manner, and a clamping positioning piece 7 is fixedly connected with the center of the outer side wall of the screw body 2; the screw body 2 is provided with a thread groove 6 in a penetrating way in the center, and the screw body 2 is separated from the hexagonal protective shell 1 for connection, so that after the nut is integrally fixed, the situation that the integral structure is problematic due to the fact that other people screw the nut without permission can be prevented, and the integral structure is protected from being damaged by utilizing the high rigidity performance of carbon steel.

As shown in the figure, the junction of the screw body 2 and the through hole 3 is connected in a rotating way through a rotating shaft 9, a plug hole 5 is formed in the side wall of one side of the screw body 2, a fixing clamping piece 8 for enabling the clamping positioning piece 7 to be at a fixed position is inserted in the plug hole 5, the clamping positioning piece 7 rotates in the inner groove 4, the height and the width of the clamping connecting piece are slightly smaller than those of the inner groove 4, the clamping positioning piece 7 slightly smaller than the space of the inner groove 4 is used for preventing mechanical abrasion, the clamping positioning piece 7 is clamped through the fixing clamping piece 8 to screw a nut, the fixing clamping piece 8 is inserted through the plug hole 5, and the screw body 2 cannot be screwed through screwing the hexagonal protective shell 1 in an unclamped state through the rotating shaft 9.

During operation, firstly, the fixing clamping piece 8 is inserted into the inserting hole 5 formed in the side wall of the hexagonal protective casing 1, the fixing clamping piece 8 clamps the clamping positioning piece 7 fixed on the side wall of the screw body 2, then the hexagonal protective casing 1 is pulled by a hexagonal wrench to screw down the screw, after the fixing clamping piece 8 is taken out, the screw body 2 is connected with the through hole 3 through the rotating shaft 9 at two ends, and when the clamping positioning piece 7 is in an unclamped movable state in the inner groove 4, the hexagonal protective casing 1 cannot be screwed to link the screw body 2 to rotate, so that the threaded groove 6 in threaded connection with the bolt cannot rotate.
