Abstract

The invention aims to disclose a bolt structure. The bolt structure comprises a head part and a screw rod, wherein external threads are arranged on the screw rod, one side of the screw rod and the bottom of the head part are fixedly connected mutually, and an inner screw hole is arranged in the other side of the screw rod; compared with the prior art, the bolt structure has the advantage that the head part only needs to be placed in the groove of a profile frame, then the bolt is enabled to be connected with a connecting corner fitting in a fastening manner through the inner screw hole arranged in one side of the screw rod, special nuts matched with the profile frame are not needed, excessive parts are omitted, the cost is effectively reduced, the assembly is facilitated, and the purpose of the bolt structure is realized.

Description

A kind of bolt arrangement
Technical field
The present invention relates to a kind of bolt arrangement, particularly relate to a kind of bolt arrangement that section material framework connects that is applicable to.
Background technique
Bolt is a kind of mechanical parts, and it is the cylindrical threaded fastening piece of adapted nut.Bolt is comprised of head and screw rod (with externally threaded cylindrical body) two-part usually, need coordinate with nut, for being fastenedly connected two parts.
The nose shape of bolt comprises hexagonal, circle, square, countersunk head etc.Wherein hexagon head is the most frequently used.
As shown in Figure 1, in the prior art, in the right angle of section material framework 10 connects, between section material framework 10, by connecting corner fittings 11, be connected to each other, connect between corner fittings 11 and section material framework 10 and be connected to each other by bolt 21 and specialized nut 22.
But such Placement is loaded down with trivial details completely, need to now specialized nut 22 be placed in the groove 12 of section material framework 10 during operation, then be connected to each other by bolt 21 and specialized nut 22.
Simultaneously, according to the section material framework 10 of different size, need the specialized nut 22 of different size to be connected with bolt 21, bolt 21 is fastened in specialized nut 22 by the inner hexagonal hole 211 of bolt 21 heads.
Therefore, need especially a kind of bolt arrangement, to solve the above-mentioned problem existed.
Summary of the invention
The object of the present invention is to provide a kind of bolt arrangement, for the deficiencies in the prior art, without the specialized nut that uses section material framework, just can realize the connection of section material framework, effectively reduced cost, and easy to assembly.
To achieve these goals, technological scheme of the present invention is as follows:
A kind of bolt arrangement, is characterized in that, it comprises head and screw rod, on described screw rod, is provided with outside thread, and a side of described screw rod is connected with the bottom of described head is fastened to each other, and the inside of the opposite side of described screw rod is provided with inner bolt hole.
In one embodiment of the invention, the center of described inner bolt hole is consistent with the center of described screw rod.
In one embodiment of the invention, the length of described inner bolt hole is 3-6mm.
In one embodiment of the invention, 1/2 of the diameter that the diameter of described inner bolt hole is described screw rod.
In one embodiment of the invention, described head be shaped as hexagonal, circle, square or countersunk head.
In one embodiment of the invention, described inner bolt hole be shaped as hexagonal or square.
Bolt arrangement of the present invention, compared with prior art, only head need be placed in the groove of section material framework, make bolt and be connected corner fittings and be fastenedly connected by the inner bolt hole that is arranged on screw rod one side, without using the specialized nut matched with section material framework, saved too much part, effectively reduced cost, convenient for assembly, realize purpose of the present invention.
Characteristics of the present invention can be consulted the detailed description of the graphic and following better mode of execution of this case and be obtained and be well understood to.
The accompanying drawing explanation
Fig. 1 is the structural representation that prior art medium section framework connects;
Fig. 2 is the structural representation of bolt of the present invention;
Fig. 3 is the generalized section of bolt of the present invention;
Fig. 4 is the scheme of installation of bolt of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Embodiment
As shown in Figures 2 and 3, bolt arrangement of the present invention, it comprises head 100 and screw rod 200, on described screw rod 200, is provided with outside thread 210, one side of described screw rod 200 is connected with the bottom of described head 100 is fastened to each other, and the inside of the opposite side of described screw rod 200 is provided with inner bolt hole 220.
In the present embodiment, described inner bolt hole 220 center is consistent with described screw rod 200 center.The length of described inner bolt hole 220 is 3-6mm.1/2 of the diameter that the diameter of described inner bolt hole 220 is described screw rod 200.
In the present embodiment, described head 100 be shaped as hexagonal, circle, square or countersunk head.
In the present embodiment, described inner bolt hole 220 be shaped as hexagonal or square.
As shown in Figure 4, during use, the head of bolt of the present invention 100 is placed in the groove 11 of section material framework 10, screw rod 200 and inner bolt hole 220 are towards the outside of section material framework 10; Then, tool using (as hexagon wrench) inserts in inner bolt hole 220 and rotation, the outside thread 210 on screw rod 200 is connected in the screw 21 that connects corner fittings 20, thereby realizes the connection between section material framework 10.
Adopt bolt arrangement of the present invention, compared with prior art, without using the specialized nut matched with section material framework, saved too much part, effectively reduced cost, convenient for assembly.
Above demonstration and described basic principle of the present invention, major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
