Abstract

A kind of nut with magnetism, including cooperating nut inside lining, magnetic ring and nut shell; wherein, a fixed magnetic ring in the nut inside lining, the nut shell of moulding plastics again forms the nut inside lining, a body structure of magnetic ring and nut shell, the utility model discloses owing to install a magnetic ring in the inside lining of lift nut, carry out the processing nut shell of moulding plastics again, let the magnetic ring parcel in the shell of moulding plastics, form a nut of taking magnetism, owing to there is the outside protection of the shell of moulding plastics, can effectually avoid the fragile phenomenon of magnetic ring to take place, prolong the life of way stake.

Description

Magnetic nut

Technical Field

The utility model relates to a supporting system of stake of way of going up and down is related to a take magnetic nut very much.

Background

Road piles are often applied to road traffic, military bases, gates and peripheries of national important organs, pedestrian streets, expressways, toll stations, airports, schools, banks, large-scale clubs, parking lots and other occasions, and a group of road piles are generally arranged according to needs to control whether a certain road section or a certain area can pass through vehicles or not.

The lifting road pile is generally buried underground during installation, and comprises an outer cylinder and an inner cylinder which is arranged in the outer cylinder and can be driven to lift, and when the lifting road pile is used, the inner cylinder is pushed out of the ground by a push rod to form the road pile.

The existing push rod structure generally comprises a guide tube, a lifting nut and a lifting rod which are matched with each other, wherein the lifting rod is fixed on the lifting nut and integrally sleeved on a screw rod, and the lifting nut is sleeved with the guide tube; the screw rod is driven by a motor to rotate, the screw rod drives a lifting nut and a lifting rod to move up and down along a guide groove in the guide pipe, the lifting rod is fixed with the road pile inner cylinder to drive the inner cylinder to ascend to a fixed position, a magnetic ring is sleeved on the lifting nut, and as shown in figure 1, the lifting nut controls the lifting height of the inner cylinder in a matching manner with an inductive switch arranged on the guide pipe in the lifting process; the existing magnetic ring is directly sleeved outside the lifting nut, and in the structure, because the magnetic ring is directly sleeved outside the lifting nut, when the lifting nut moves up and down, the magnetic ring can collide with the inner wall of the guide pipe to be impacted, so that the magnetic ring is easy to break, and the service life of a road pile is influenced.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a take magnetic nut, its simple structure, simple to operate has solved the difficult problem of industry, prolongs the life of road pile.

In order to achieve the above purpose, the technical solution of the present invention is as follows:

a kind of nut with magnetism, including cooperating nut inside lining, magnetic ring and nut shell; wherein, a magnetic ring is fixed in the nut liner, and then the nut shell is injected to form an integrated structure of the nut liner, the magnetic ring and the nut shell.

Furthermore, the shell is provided with a limit stop.

After the scheme is adopted, the utility model discloses owing to install a magnetic ring in the inside lining of lift nut, carry out injection moulding nut shell again, let the magnetic ring parcel in the shell of moulding plastics, form a nut of taking magnetism, owing to there is the outside protection of shell of moulding plastics, can effectually avoid the fragile phenomenon of magnetic ring to take place, prolong the life of road pile.

fig. 2 is a schematic view of the assembly of the nut liner and the magnetic ring of the present invention;

fig. 3 is a schematic structural diagram of the present invention.

Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

As shown in fig. 2-3, a magnetic nut includes a nut liner 1, a magnetic ring 2 and a nut shell 3, which are mutually matched; wherein, a magnetic ring 2 is fixed in the nut liner 1, and then the nut shell 3 is injection molded to form an integrated structure of the nut liner, the magnetic ring and the nut shell. The shell can be provided with a limit stop matched with other parts.

The utility model discloses owing to install a magnetic ring in the inside lining of lift nut, carry out injection moulding nut shell again, let the magnetic ring parcel in the shell of moulding plastics, form a nut of taking magnetism, owing to there is the outside protection of moulding plastics the shell, can effectually avoid the breakable phenomenon of magnetic ring to take place, prolong the life of road pile. The utility model discloses seem simple institutional advancement, but it has solved the industry and has walked around the difficult problem of a long time.

While the foregoing description shows and describes the preferred embodiments of the present invention, it is to be understood that the invention is not limited to the forms disclosed herein, but is not intended to be exhaustive or to exclude other embodiments and may be used in various other combinations, modifications, and environments and is capable of changes within the scope of the inventive concept as expressed herein, commensurate with the above teachings, or the skill or knowledge of the relevant art. But that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention, which is to be limited only by the claims appended hereto.

Claims (2)

1. A magnetic nut is characterized by comprising a nut liner, a magnetic ring and a nut shell which are matched with each other; wherein, a magnetic ring is fixed in the nut liner, and then the nut shell is injected to form an integrated structure of the nut liner, the magnetic ring and the nut shell.

2. The magnetic nut of claim 1 wherein said housing defines a limit stop.
