Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a bolt fastener of inflation formula high strength, includes nut 2, sleeve pipe 5 and bolt 7, and the left side of sleeve pipe 5 is provided with opening 6, and flat gasket 4 is installed on the right side of sleeve pipe 5, and the top of bolt 7 is provided with screw thread 1, and bolt 7 is located sleeve pipe 5's inside, and the left side of nut 2 is provided with spring washer 3, and nut 2 is located sleeve pipe 5's right side, and the right side fixedly connected with top 8 of bolt 7, and top 8 left side fixedly connected with tip 9.

The utility model discloses in: the sleeve 5 and the opening 6 are of an integrated structure, and the inner dimension structure of the sleeve 5 is the same as the outer dimension structure of the bolt 7; the opening 6 at the tail part of the sleeve 5 effectively fixes the bolt 7 in the fixing body through the top 8 at the tail part of the bolt 7, and the bolt 7 facilitates the fixing of the fixing body and the connecting piece together, thereby effectively preventing the connecting piece from falling.

The utility model discloses in: the central axis of the thread 1 is coincident with the central axis of the bolt 7, and the external dimension structure of the bolt 7 is the same as the internal dimension structure of the nut 2; fix through the effectual fixed body of messenger of bolt 7 and nut 2 and connecting piece, the effectual not hard up that prevents the connecting piece drops even and can not injure the less repair cost to the connecting piece of people by a crashing object.

The utility model discloses in: the left side surface of the flat gasket 4 is tightly attached to the right side surface of the spring gasket 3, and the central axis of the spring gasket 3 is superposed with the central axis of the nut 2; strengthen and prevent the pine and take off between the fixed body and the connecting piece through spring gasket 3, the long-term vibrations of fixed body and connecting piece, the combination of nut 2 and screw thread 1 may become flexible or even drop, when the spring gasket 3 of cover on screw thread 1, behind nut 2 and the bolt 7 is fixed, the elasticity through spring gasket 3 effectively reduces the not hard up of nut 2, the possibility that drops.

The utility model discloses in: the bolt 7 penetrates through the interior of the flat gasket 4, and the outer wall of the bolt 7 is tightly attached to the inner wall of the spring gasket 3; through the effect of flat gasket 4 increase friction power, play the area of contact of increase fixed body and surperficial between the sleeve pipe 5, reduce the fixed body and to the pressure between the sleeve pipe 5 and the effect that the protection is not impaired by the connecting piece surface, prevented that nut 2 is not hard up to it is not hard up to make fixed body and connecting piece.

The utility model discloses in: the top 8 and the bolt 7 are of an integrated structure, and the left surface of the top 8 is tightly attached to the right surface of the tip cone 9; the bolt 7 is conveniently fixed on the fixing body through the tip cone 9, the bolt 7 and the sleeve 5 are conveniently taken out of the fixing body during disassembly, excessive force and damage to the fixing body around the bolt 7 are not needed, and therefore the attractiveness of the fixing body is affected, and the fixing body is required to be repaired after the bolt 7 is taken out.

This inflation formula high strength's bolt fastener's theory of operation: when the bolt is used, firstly, a hole with a corresponding size is drilled on a fixed body by using an impact electric drill, then the bolt 7 is fixed on the fixed body by the bolt 7 through the tip cone 9, the bolt 7 cannot fall off, then the sleeve 5 is arranged on the bolt 7, then the flat gasket 4 and the spring gasket 3 are arranged, and the bolt 7, the sleeve 5, the connecting piece and the fixed body can be expanded and integrated into a whole by screwing the nut 2 through the thread 1, so that the connecting piece cannot easily fall off, and the fixed body and the connecting piece are reinforced and prevented from loosening through the spring gasket 3;

secondly, the nut 2 is screwed down and expanded, the tail part of the bolt 7 is provided with a top 8, the outer surface of the bolt 7 is sleeved with a sleeve 5 with a diameter slightly larger than that of the bolt 7, and because the tail part of the sleeve 5 is provided with a plurality of openings 6, after the bolt 7 is screwed down, the opening 6 at the tail part of the sleeve 5 is brought to the top 8, the opening 6 is punched to be large through the top 8, so that the purpose of expansion is achieved, and the bolt 7 is fixed on the ground or the wall, so that the purpose of fastening is achieved.

At last screw off nut 2 earlier when dismantling, take off spring shim 3 and plain gasket 4 again, will drive sleeve pipe 5 through rotatory bolt 7 and directly come out, need not directly pound the fixed body around bolt 7 and take out the bolt again, convenient and fast has reduced the cost of restoreing the fixed body and has accelerated the time of getting bolt 7 and sleeve pipe 5.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
