Abstract
This invention is a code bolt for safty. Through turning a joint pin changes the turning direction of the screw cap and the screw. The turning of the joint pin is controlled by a round flat lock which has groove cut inside. With a correct code, could the lock's groove be turned to the right position to turn the joint pin then the turning together of the screw cap and the screw.
Description
One, affiliated technical field
The invention belongs to the anti-theft bolt field, use conventional spanner, cooperate password to dismantle easily or to tight a bolt, and can prevent effectively that other people from stealing and tear open.
Two, technical background
Present known anti-theft bolt technology, what have has adopted special shape at the bolt screw terminal, only needs to cooperate relative special key, and see China Patent No.: 0029025.5 anti-theft effect is undesirable; The employing that has rivets mode or other interlock mode, though played the purpose that anti-other people robber tears open, same difficulty is very big when dismantling voluntarily.
Three, summary of the invention
In order to overcome the deficiency of existing anti-theft bolt technology, the invention provides a kind of simple in structure, cost is low, and is easy and simple to handle, only the cipher burglarproof bolt that needs conventional spanner to mount and dismount easily can be widely used in various fastener areas.
The present invention is achieved by the following technical solutions:
The screw terminal of bolt is made into cylindrical body, and the cylindrical body middle part has the jump ring groove, and the cylindrical body top is provided with a non-circular projection or has the groove of arbitrary shape.One end of six square nuts is established interior hollow-cylindrical, and the middle part opens that jump ring groove position is identical with cylindrical body jump ring groove, and this end is enclosed within on the bolt circle cylinder, is Spielpassung between the two.The interior hollow-cylindrical end of six square nuts be provided with one with bolt circle cylinder top corresponding device is set, the former size is greater than the latter, after six square nuts are enclosed within on the cylindrical body, blocked that by jump ring the two can not be separated, at this moment six square nuts can rotate and but can not drive screw rod and rotate.The other end of six square nuts is provided with one group by connecting pin, the connecting pin sleeve pipe, the composite set of the connecting pin locking annulus of symbol is carved with in outer ring more than two, the side of connecting pin is provided with the prominent nail identical with connecting pin locking number of rings, the top is provided with a connecting sheet, and the geomery of connecting sheet just in time can fill up the space between six square nut built-ins and the bolt circle cylinder top projection.Adopt the connecting pin locking annulus more than two, be separated with rounded washers between per two locking annulus, locking annulus and rounded washers inboard have same groove, and groove just in time allows the prominent nail of connecting pin to pass through.Have several grooves on the connecting pin sleeve pipe, the size of one of them groove is identical with groove size on the locking annulus; Locking annulus and rounded washers stack at interval be enclosed within the connecting pin sleeve pipe outer after, compression sleeve fluting end enters in the circular hole that six square nuts, one end offers it, sleeve pipe recovers shape, the boss on top is closely as one the two can not to separate.From the other end connecting pin is put into, made the prominent nail of connecting pin aim at and enter locking ring groove group, at this moment the combination of six square nuts is locked on the bolt circle cylinder by jump ring, a cover cipher burglarproof bolt assembling finishes.Can drive screw rod when rotating six square nuts and rotate, depend on that can connecting pin move on the cylindrical body projection, is connected as a single entity six square nuts and bolt.Moving of connecting pin lived in connecting pin locking annulus combination effectively locking, and the groove that can depend on correctly access to your password adjusts locking annulus group inboard makes it to be on the same straight line.Stir connecting pin six square nuts be connected with bolt, after tighting a bolt, dial back connecting pin, rotate the locking annulus and dial random password, pin connecting pin, at this moment this bolt other people can't dismantle.
Four, diagram
Figure (1) is the structural drawing of cipher burglarproof bolt
Five, specific embodiments
Embodiment with regard to cipher burglarproof bolt is described further in conjunction with composition below.Among the figure (1), an end of connecting pin sleeve pipe 1 has the multiple tracks groove, is enclosed within outside the connecting pin sleeve pipe 1 after connecting pin locking annulus 8, rounded washers 9 stacks.The fluting end of extruding connecting pin sleeve pipe 1 makes in its circular hole that enters six square nuts 2, and when being pressed onto, sleeve pipe 1 recovers shape.Rotate locking annulus 8, rounded washers 9 is adjusted inboard groove and is in same straight line, and the prominent nail alignment indentation on the connecting pin is packed in the connecting pin sleeve pipe 1.With the jump ring 11 jump ring groove 10 of packing into, be changed to cylindrically in six square nuts, 2 the other ends, the inner is provided with interior side, and interior cylindrical and cylindrical body 6 are Spielpassung, the cylindrical body 6 of bolt 7 is pressed in six square nuts 2, and the jump ring groove combination that jump ring 11 is blocked in six square nuts finishes.
Direction to cylindrical body 6 promotes connecting pin 3, makes connecting sheet 4 entangle convex 5, crosses connecting sheet 4 stubborn convexes 5 with the interior square tube that spanner turns in six square nuts, 2, six square nuts 2, drives screw rod 7 rotations and tights a bolt.Deviate from the direction of bolt 7 and stir connecting pin 3, connecting sheet 4 is separated with convex 5, rotate locking annulus 8 and upset the relative position of locking annulus inboard groove, connecting pin is placed restrictions on and can not be moved under the effect of prominent nail 12, at this moment can't come demounting bolt by turning six square nuts 2.
Adjust to same linear state according to password elder generation 8 all inboard grooves of rotation locking annulus during dismounting, promotion connecting pin 3 makes connecting sheet 4 entangle convex 5, and it is promptly dismountable that the use spanner rotates six square nuts 2.
Claims (4)
1, a kind of cipher burglarproof bolt, by connecting pin sleeve pipe 1, six square nut 2, connecting pin 3, prominent nail 12, connecting sheet 4, convex 5, bolt circle cylinder 6, bolt 7, connecting pin locking annulus group 8, rounded washers 9, jump ring groove 10, jump ring 11 is formed.
2, according to claim 1 described cipher burglarproof bolt, it is characterized in that: connecting pin locking annulus adopts the combination more than two, and interior ring one side recessing also can be provided with projection.
3, according to claim 1 described cipher burglarproof bolt, it is characterized in that: when only the groove of ring one side or projection were adjusted on the certain location in connecting pin locking annulus, six square nuts could be with screw rod to rotate.
4, according to claim 1 described cipher burglarproof bolt, it is characterized in that: the cross section of connecting pin can be a random geometry, and the projection of connecting sheet and screw tip or fluting can be any geometrical shapies except that circular.
