Description
Technical field
This utility model belongs to technical field of fastening, particularly to a kind of novel spiral screw bolt and nut.
Background technology
Bolt, the threaded securing member of cylinder of adapted nut.By head and screw rod（With externally threaded cylinder）
A class securing member dimerous, needs and nut screw connection, for being fastenedly connected two parts carrying through hole.
Spherical shell rack engineering in construction because span is big, highly high, horizontal thrust is big, amount of high-altitude operation is big, spell by high-altitude
Dress construction is an engineering construction smoothly big key, how high-quality, and the complete cost engineering Construction of Steel Structure of safety is that we are necessary
The problem taken seriously.During spherical shell Construction of The Grids, need to use substantial amounts of bolt connection, the connector of spherical shell rack is past
Toward extending in all direction, there is the type of attachment of multiple directions, at this moment traditional screw bolt and nut is due to the contact site and connector between
Position is planar structure, easily produces the phenomenon of discontinuity, leads to screw bolt and nut to damage, shortens the use of screw bolt and nut
Life-span.
Content of the invention
The purpose of this utility model is to provide a kind of novel spiral screw bolt and nut, and this screw bolt and nut is reasonable in design,
Easy to use, it is connected firmly, more safety and stability during work, stress is not when contacting with connector for effectively solving screw bolt and nut
Uniform problem, has high use value.
The purpose of this utility model is realized in：A kind of novel spiral screw bolt and nut, including bolt and matched
Nut, described bolt is made up of the bolt body of rod and bolt head, and the described bolt body of rod and bolt head are integrally formed setting, described
Nut on be provided with bolt hole, the first half of described bolt head is hexagonal cylinder, lower half is hemisphere, described nut
For spherical nut, described nut is provided with two blind holes parallel with bolt hole.
The height of the first half hexagonal cylinder of described bolt head is the 2/3 of lower half hemisphere radius.
The axis of described bolt hole crosses the centre of sphere of nut.
Described blind hole is arranged with regard to the axisymmetrical of bolt hole.
The 1/4 of a diameter of diameter of bolt hole of described blind hole, the depth of described blind hole is 2 times of blind hole diameter.
This utility model produce beneficial effect be：A kind of novel spiral screw bolt and nut, by the bottom of bolt head and nut
It is designed as spherical structure, the sphere that will be set at component bolt connection mutually agree with this utility model screw bolt and nut shape
Shape, increased the contact area between bolt, nut and component, makes being more uniformly stressed between bolt, nut and component, keeps away
Exempt from stress concentration phenomenon, extend bolt, the service life of nut, the stability of enhancing structure.In addition, setting in the bottom of nut
Put two blind holes, when tightening bolt, be inserted in blind hole with special instrument, prevent nut rotation.

Specific embodiment
Below in conjunction with the accompanying drawings to embodiment further instruction of the present utility model.
Embodiment 1
As shown in accompanying drawing 1-5, a kind of novel spiral screw bolt and nut, including bolt 1 and matched nut 2, described spiral shell
Bolt 1 is made up of the bolt body of rod 3 and bolt head 4, and the described bolt body of rod 3 and bolt head 4 are integrally formed setting, described nut 2
On be provided with bolt hole 5, the first half of described bolt head 4 is hexagonal cylinder, lower half is hemisphere, and described nut 2 is
Spherical nut, described nut 2 is provided with two blind holes 6 parallel with bolt hole.
The height of the first half hexagonal cylinder of described bolt head 4 is the 2/3 of lower half hemisphere radius.
The axis of described bolt hole 5 crosses the centre of sphere of nut 2.
Described blind hole 6 is arranged with regard to the axisymmetrical of bolt hole 5.
The 1/4 of a diameter of bolt hole 5 diameter of described blind hole 6, the depth of described blind hole 6 is the 2 of blind hole 6 diameter
Times.
This utility model is when using：A kind of novel spiral screw bolt and nut, including bolt and matched nut, bolt by
The bolt body of rod and bolt head composition, bolt head be set to the first half be hexagonal cylinder and lower half be hemispheroidal structure, bolt
The outside of the body of rod is provided with external screw thread, and the bolt in the hole of nut is provided with the female thread mutually agreeing with external screw thread.During use, by spiral shell
It is consistent with bolt, nut shape that tightening latch body passes through component to be connected, component to be connected and bolt, nut contact site to be set to
Spherical structure；Then, one end nut not being had blind hole is directed at the lower end of the bolt body of rod, is screwed on the bolt body of rod；Finally, use
Corresponding instrument is inserted in the blind hole of nut and blocks nut, prevents nut rotation, is directed at the six of bolt head afterwards with spanner
Bolt is tightened by prism further.
Generally, this utility model has the advantages that structure is simple, connection is firm, stress performance is good, long service life.
