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.
Referring to fig. 1-3, the present invention provides an embodiment: a kind of anti-loose theft-proof high strength bolt, including the bolt head 2, the bottom of the bolt head 2 has threaded spindles 1, the inside of the bolt head 2 has regular pentagon hole 3, the regular pentagon hole 3 that the bolt head 2 sets up and regular hexagon post 4 of the top of the rotatory dead lever 5, let this bolt distinguish from other bolts, can only use the tool of the special regular pentagon head and tool of the embedded regular hexagon post hole head, can install and dismantle this each bolt, there is very strong theft-proof performance, the bottom of the regular pentagon hole 3 has round holes 9, the inside of the threaded spindle 1 has rotatory dead lever 5, and the external surface of the rotatory dead lever 5 has spiral lines, can use the special tool to rotate the rotatory dead lever 5, the rotatory dead lever 5 moves down, promote the fixed part that the rotatory dead lever 5 connects inside the bolt downward together, through pushing, the bolt is transversely fixed, the bolt can not slide when having guaranteed vertical vibrations, upwards run, lead to becoming flexible to drop, and the security performance of facility improves greatly, and the one end of rotatory dead lever 5 is provided with regular hexagon post 4, and the other end of rotatory dead lever 5 is provided with montant 6, and the bottom of montant 6 is provided with connecting rod 7, and connecting rod 7 has two.
Further, montant 6 is connected through the pivot rotation with connecting rod 7, and the other end of connecting rod 7 is provided with prevents loose piece 8, and montant 6 downstream under the promotion of rotatory dead lever 5, two connecting rods 7 that montant 6 is being connected, the laminating is in the inside of screw rod 1 below, so they two respectively to both sides removal, and the flare angle grow gradually between the two, this lets the removal that the reinforcement part can be smooth and easy.
Further, locking piece 8 passes through slide sliding connection with screw rod 1, and connecting rod 7 rotates through the pivot with locking piece 8 to be connected, and locking piece 8 is under the effect of connecting rod 7 to both sides opening force, and locking piece 8 slowly comes out from screw rod 1 is inside, transversely consolidates the bolt, and the bolt can not the smooth silk when letting the external world produce vertical vibrations to the bolt, upwards run, lead to becoming flexible to drop.
Further, rotatory dead lever 5 is connected through the internal thread rotation with screw rod 1, and rotatory dead lever 5 and regular hexagon post 4 welded connection make the bolt internals fixed firm, can not be when not installing the bolt yet, prevent that the loose piece just comes out, lead to the construction bolt failure.
Further, the rotating fixing rod 5 is rotatably connected with the vertical rod 6 through the rotating shaft, so that when the rotating fixing rod 5 moves downwards in a rotating mode, the vertical rod 6 only moves downwards and does not rotate, the reinforced parts inside the bolt move downwards stably, no rotating offset exists, the whole process is very smooth, and the bolt head 2 is connected with the screw rod 1 in a welding mode.
The working principle is as follows: when the tool is used, whether the bolt is damaged or not is checked firstly, then the tool for installing the specific regular pentagon head of the bolt and the tool with the cylindrical appearance and the regular hexagon head as the inner wall are taken out, the bolt can be installed, the bolt is placed above the hole needing to be installed firstly, then the tool for installing the regular pentagon head is taken out and placed in the regular pentagon hole 3 of the bolt head 2, then the tool for installing the regular pentagon head is rotated, the bolt enters the hole needing to be installed, after the bolt completely enters the hole, the tool for installing the regular pentagon head is taken out from the regular pentagon hole 3 of the bolt head 2, another tool with the cylindrical appearance and the regular hexagon head as the inner wall is taken out and placed in the circular hole 9 of the bolt head 2, the inside of the tool is correspondingly attached to the regular hexagon column 4, then the tool is rotated, the rotary fixing rod 5 connected with the regular hexagon column 4 is rotated downwards, the rotary fixing rod 5 is rotated on the vertical rod 6 through the rotating shaft, promote montant 6 downstream, two connecting rods 7 that montant 6 is being connected, the laminating is in the inside of screw rod 1 below the connecting rod 7, so they two respectively to both sides removal, the opening angle grow gradually between the two, prevent loose piece 8 under the effect of connecting rod 7 to both sides opening force, loose piece 8 slowly comes out from screw rod 1 is inside, consolidates the bolt, consolidate the back that targets in place, just can the stall, take away the instrument of installation and use, the bolt has just been installed.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
