Abstract
The utility model belongs to a self-locking type fastening bolt used for buildings, which comprises a screw bolt of which one end forms an outer screw with definite length and a nut, wherein the other end of the screw bolt forms an opening groove which can hide a tooth-shaped hook in the groove; the end part of the opening groove is fixed with a tooth-shaped hook which of which the width is little smaller than the diameter the screw bolt and both sides form saw teeth with definite length. The self-locking type fastening bolt overcomes the defects that original self-locking type fastening bolts is only suitable for being used in entity positions, can not be used in hollow positions, easily cause fastening bolts to be loosen and have influence on the installation of tighteners, and the characteristic of different weight of both sides of the tooth-shaped hook of the self-locking fasterning bolt is ued for causing the fastening bolt to use self weight for forming a T-shaped hook and completing fixed fastening.
Description
Technical field
The invention belongs to a kind of clamping bolt for building, particularly relate to a kind of self-locking clamping bolt for building of suitable hollow part.
Background technique
Present self-locking clamping bolt for building (being commonly called as the pipe that rises) is to be formed with tapering by an end, and the other end forms threaded bolt 1 and inside is formed with through hole, and an end is formed with the sleeve pipe 2 and the nut 3 of cross opening slot and forms.Or be formed with screw thread by an end, the other end be formed with the cross opening slot and from be formed with screw thread one end to opening slot be formed with the bolt 4 of endoporus and slightly be longer than in hole length and form with steel nail 5 and nut 3 that endoporus is slidingly matched.But above-mentioned two kinds of self-locking clamping bolts only are adapted at physical location to be used.Powerless for hollow part, cause clamping bolt loosening easily, influence the installation of fastener.
Summary of the invention
The present invention provides a kind of self-locking clamping bolt for building of suitable hollow part for solving the technical problem that exists in the above-mentioned technology.
The technological scheme that the present invention takes for the technical problem that exists in the above-mentioned technology of solution is:
A kind of self-locking clamping bolt of the present invention, bag Chinese juniper one end is formed with externally threaded bolt of certain-length and nut, the other end of bolt is formed with the opening slot that the long end of profile of tooth hook can be concealed in the groove, has certain-length in the end of opening slot by fixing pin being fixed with movingly, its width is slightly less than the diameter of bolt, and both sides form serrate profile of tooth hook.The distance of the fixed pin holes of profile of tooth hook and profile of tooth hook one side end is greater than the distance of end side, the opening slot length of bolt is greater than the distance of the long end of profile of tooth hook linchpin hole distance profile of tooth hook one side, and bolt is formed with the screw of certain depth in the end that the outside thread side is arranged.
Advantage and good effect that the present invention has are: a kind of self-locking clamping bolt of the present invention has overcome former self-locking clamping bolt and only has been adapted at the physical location use, powerless for hollow part, cause clamping bolt loosening easily, influence the shortcoming of the installation of fastener, the characteristics of utilizing a kind of self-locking clamping bolt profile of tooth hook of the present invention both sides to vary in weight make clamping bolt utilization deadweight after passing solid wall to arrive hollow part form T font hook, finish fixing and locking.

Embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
Fig. 3 is the user mode figure of self-locking clamping bolt of the present invention, and Fig. 4 is the plan view of self-locking clamping bolt of the present invention, the side view of Fig. 5 during for the use of self-locking clamping bolt of the present invention.
Self-locking clamping bolt of the present invention, bag Chinese juniper one end is formed with externally threaded bolt 6 of certain-length and nut 3, the other end of bolt 6 is formed with the opening slot 9 that profile of tooth hook 7 long ends can be concealed in the groove, has certain-length in the end of opening slot 9 by fixing pin 8 being fixed with movingly, its width is slightly less than bolt 6 diameters, and both sides form serrate profile of tooth hook 7.The distance of the fixed pin holes of profile of tooth hook 7 and profile of tooth hook 7 one side ends is greater than the distance of end side, and opening slot 9 length of bolt 6 are greater than the distance of profile of tooth hook fixed pin holes to long end one side, and bolt 6 is formed with the screw of certain depth in the end that the outside thread side is arranged.
Use of the present invention is elaborated, when when hollow part such as roof orifice plate, hollow wall are installed the self-locking clamping bolt, in real outside empty position bore one with the identical hole of bolt 6 external diameters, profile of tooth hook 7 and bolt 6 suitable being in line, when bolt 6 installation directions are below or side, the long-armed of profile of tooth hook placed outside the bolt 6, and bolt 6 installation directions are when top, and the galianconism of profile of tooth hook is placed outside the bolt 6.It is pushed in the hole, after passing solid wall arrival hollow part, profile of tooth hook 7 serves as that the characteristics that axle utilization varies in weight make profile of tooth hook 7 and bolt 6 form T font hook also with nut 3 lockings with the fixing pin 8 that is fixed on opening slot 9 ends, fastening along with nut 3, the sawtooth of profile of tooth hook 7 is pricked into body of wall, prevents that bolt 6 from rotating.Because opening slot 9 length of bolt 6 greater than the distance of profile of tooth hook fixed pin holes to long end one side, when needs dismounting clamping bolt, come loose nut 3, and bolt 6 is advanced, and utilize gravity to make profile of tooth hook 7 revert to straight line, can extract clamping bolt.Have the end of outside thread side to be formed with the screw of certain depth at bolt 6, when bolt 6 all advanced body of wall, available screw was screwed into screw bolt 6 is pulled out.
The present invention can make the clamping bolt of different materials, different size as required, to satisfy different needs.
