Description

Hexagon nut

Technical Field

The utility model relates to a nut technical field especially relates to a hexagon nut.

Background

With the development and progress of society and the rapid development of machine manufacturing, the use of hexagonal nuts, which are fasteners having internal threads and used in cooperation with bolts and mechanical parts having internal threads and used in cooperation with screws for transmitting motion or power, is becoming more and more frequent.

When using, the existing hexagonal nut mostly utilizes a wrench or other tools to clamp the edges and corners of the hexagonal nut, then works, the existing hexagonal nut is usually an outer hexagon, the wrench of the inner hexagon can only be used for rotating, and the nut can not be rotated by the outer hexagon wrench.

SUMMERY OF THE UTILITY MODEL

To the current situation of above-mentioned prior art, the utility model aims to solve the technical problem that a hexagonal nut is provided to solve prior art problem.

The utility model provides a technical scheme that above-mentioned technical problem adopted does:

the utility model provides a hexagon nut, includes interior cylinder and outer hexagonal cylinder, interior cylinder fixed connection is inboard at outer hexagonal cylinder, outer hexagonal cylinder includes first cylinder and second cylinder, and the cross-section of this first cylinder and second cylinder is regular hexagon, and this first cylinder and second cylinder integrated into one piece, this first cylinder setting are in second cylinder upper end, and this first cylinder up end undercut is equipped with interior hexagonal recess, and this interior hexagonal recess is located directly over the interior cylinder, interior hexagonal recess is linked together with the interior cylinder.

Preferably, the side length of the first cylinder is smaller than that of the second cylinder, so that the wrench is suitable for internal hexagon wrenches of different models.

Preferably, the lower end of the second cylinder is provided with an outer ring, the outer ring is connected with the outer end face of the second cylinder, and the lower surface of the outer ring is provided with anti-skidding teeth which can play a role in looseness prevention after the nut is screwed down.

Preferably, the inner surface of the inner cylinder is provided with internal threads, the inner diameter of the inner cylinder is larger than that of the inner hexagonal groove, the internal threads are not completely led out, and the effective installation stroke of the internal threads and the effective torque of the inner hexagonal groove can be ensured.

Compared with the prior art, the utility model has the advantages of:

through setting up hexagon socket head cap groove and outer hexagonal cylinder, can realize that multitool installs fast and dismantles, ensures when one of them outer hexagonal or hexagon socket head cap goes wrong or an instrument goes wrong, still has the instrument to install and dismantle, the utility model relates to a rationally, accord with the market demand, be fit for promoting.

Detailed Description

As shown in fig. 1-4, the hexagonal prism comprises an inner cylinder 4 and an outer hexagonal cylinder, the inner cylinder 4 is fixedly connected to the inner side of the outer hexagonal cylinder, the outer hexagonal cylinder comprises a first cylinder 1 and a second cylinder 2, the cross sections of the first cylinder 1 and the second cylinder 2 are both regular hexagons, the first cylinder 1 and the second cylinder 2 are integrally formed, the first cylinder 1 is arranged at the upper end of the second cylinder 2, an inner hexagonal groove 5 is recessed downwards on the upper end surface of the first cylinder 1, the inner hexagonal groove 5 is located right above the inner cylinder 4, and the inner hexagonal groove 5 is communicated with the inner cylinder 4.

The external hexagon wrench can be inserted into the internal hexagon groove 5 to rotate the hexagon nut, the internal hexagon wrench can be sleeved on the first cylinder 1 or the second cylinder 2 to rotate the hexagon nut, the sections of the first cylinder 1 and the second cylinder 2 are both regular hexagons, because the side lengths of the first cylinder 1 and the second cylinder 2 are different, the nut wrench can adapt to internal hexagonal wrenches with different sizes, the problem that the nut can only be rotated by one wrench is solved by combining the internal hexagonal groove 5 with the first cylinder 1 and the second cylinder 2, the lower end of the second cylinder 2 is provided with the outer ring 3, this 3 lower surfaces of outer loop are equipped with anti-skidding tooth, can play locking effect after screwing up the nut, and internal thread has been seted up to 4 internal surfaces of interior cylinder, and the internal diameter of interior cylinder 4 is greater than the internal diameter of hexagon socket head cap groove 5, and the internal thread does not lead to completely, can ensure that the effective installation stroke of internal thread also can ensure hexagon socket head cap groove 5 effective moment.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes in the embodiments and modifications thereof may be made, and equivalents may be substituted for elements thereof; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
