Description

A kind of new type nut column

Technical field

The utility model belongs to connector technical field, concretely relates to a kind of new type nut column.

Background technique

Nut and stud or screw rod are threaded together the part for playing the role of fastening, by the screw thread on the inside of nut, on an equal basis Specification nuts and bolt can just link together.

It needs to be attached two screw rods by a nut, traditional mode includes: 1, directly by two screw rods point Not from the both ends precession of nut, will cause in this way it is more in a screw rod precession nut, it is less in another screw rod precession nut, Later period will affect stress condition of two screw rods at nut, be likely to result in two screw rods in the position unbalance stress of nut, It is easily broken off, there are security risks；2, according to the length of nut, upper corresponding label is done in the end of two screw rods, then again By screw rod precession nut, but it is cumbersome in this way, it is also possible to the case where measuring and mark there are no tool.

Summary of the invention

The purpose of the utility model is to provide a kind of new type nut columns can facilitate two without handling screw rod The screw rod of side quickly connects, while the screw rod uniform force of two sides.

In order to solve the above technical problems, purpose of the utility model is realized as follows:

A kind of new type nut column, including main body；Body interior is tapped with internal screw thread；The internal screw thread in main body middle position is inwardly dashed forward It rises and forms convex block, convex block destroys the complete structure of internal screw thread；The both ends of main body are threaded with connector, and the connector at both ends is stretched Enter being equidistant for body interior.

Preferred embodiment on the basis of above scheme and as above scheme: connector is screw rod or screw-thread steel.

Preferred embodiment on the basis of above scheme and as above scheme: convex block is round table-like, the bottom surface of convex block Diameter is proportional to the major diameter of internal screw thread, and the upper bottom surface of convex block is higher by 0.2-1 millimeters than internal screw thread crest.

Preferred embodiment on the basis of above scheme and as above scheme: when the internal diameter of internal screw thread is 8 millimeters, convex block Bottom surface diameter be 0.8 millimeter.

Preferred embodiment on the basis of above scheme and as above scheme: convex when the internal diameter of internal screw thread is 10 millimeters The bottom surface diameter of block is 1 millimeter.

Preferred embodiment on the basis of above scheme and as above scheme: convex when the internal diameter of internal screw thread is 20 millimeters The bottom surface diameter of block is 2 millimeters.

Preferred embodiment on the basis of above scheme and as above scheme: the edge of main body be round, hexagon or Octagon.

Compared with the prior art, the utility model has prominent and beneficial technical effects that:

The new type nut column of the utility model comprising main body, the edge of main body are octagon, on octagon most preferably It selects, not only saved material but also is conducive to install；Body interior is tapped with internal screw thread, and internal screw thread is used to connect the screw rod or screw-thread steel at both ends, The internal screw thread in main body middle position forms convex block to inner process, and for convex block at round table-like, the upper bottom surface of convex block is higher than internal screw thread crest 0.1-1 millimeters out, the bottom surface diameter of convex block is proportional to the major diameter of internal screw thread, and convex block can destroy internal screw thread from middle position Complete structure, the screw rod or screw-thread steel that can be realized both ends in this way be not in the case where making any mark, direct precession main body, simultaneously Also ensure being equidistant for both ends screw rod or screw-thread steel precession main body.

Detailed description of the invention

Specific embodiment

The utility model is further described with specific embodiment with reference to the accompanying drawing；

This gives a kind of new type nut columns comprising main body 01, the edge of main body are round, hexagon or eight Side shape, in the outer diameter of main body, using under length, material, internal screw thread same case, octagon is optimal selection；Circular edges Although the main body materials on edge most save, its surface is smooth to be unfavorable for rotation dismounting, and the main body at hexagon edge is that materials are most, But its relative to circular edges edge main body but also with feature convenient for disassembly and assembly, the materials of the main body at octagon edge are between circular edges Along between hexagon edge, while octagon edge has had both feature easy to disassemble again, in conclusion octagon edge Main body is optimal selection；

Body interior is tapped with internal screw thread 010, and the internal screw thread in main body middle position forms convex block 011 to inner process, and convex block is used In the thread for destroying internal screw thread middle position, main body is made of cold pier and cold-extrusion technology, the outer surface of main body internally Stamp out convex block, it is easily manufactured；Convex block be it is round table-like, the bottom surface diameter of convex block is proportional to the major diameter of internal screw thread, convex block Upper bottom surface 012 is higher by 0.2-1 millimeters than internal screw thread crest, and the part that convex block is higher by internal screw thread crest can destroy entire internal screw thread Complete structure so that internal screw thread is disconnected in bump position, screw rod or screw-thread steel after precession main body reaches middle position because There are convex block, will make spiral shell or screw thread steel pole that can not continue precession, and convex block is in the position of main body, thus the screw rod at both ends or Screw-thread steel protrudes into being equidistant for body interior, and the screw rod or screw-thread steel stress at both ends can be uniform；Both ends can also use other Connector, the surface of connector has screw thread, and can be formed and be threadedly coupled with main body.

When the internal diameter of internal screw thread is 8 millimeters, the bottom surface diameter of convex block is 0.8 millimeter；The internal diameter of internal screw thread is 10 millimeters When, the bottom surface diameter of convex block is 1 millimeter；When the internal diameter of internal screw thread is 20 millimeters, the bottom surface diameter of convex block is 2 millimeters；It is convex The bottom surface diameter of block is 0.1 times of the internal diameter of internal screw thread, can reach destruction internal screw thread barrier screw rod or screw-thread steel continues to revolve Into.

Use process, two screw rods or screw-thread steel are without carrying out special marking, and operator is directly by a screw rod or spiral shell For line steel from one end precession of main body, precession can not just be carried out again by waiting after screwing into bump position, by another screw rod or screw-thread steel From the direct precession of the other end of main body, another screw rod or screw-thread steel are also that can not just be revolved again after screwing into bump position Into being equidistant for, two screw rods or screw-thread steel precession body interior, under stress condition, the screw rod or screw-thread steel at main body both ends Stress in junction be it is identical, it is more more convenient than traditional approach, connect it is stronger.

Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this It encloses, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by the protection of the utility model Within the scope of.
