The cup cover-shaped anti-theft and anti-loosing screw bolt assembly comprises a right-and-left screw bolt, a standard nut, a retreat stopping cushion, and a cup-shaped protective cover, wherein, more than two retreat stopping grooves are arranged on a screw bolt post of the right-and-left screw bolt lengthways, and the top end of the screw bolt post of the right-and-left screw bolt is inwards tapped with a reverse screw hole; the lower end of the standard nut screwed on the right-and-left screw bolt is sheathed with the retreat stopping cushion, a retreat stopping spring piece is fixed to the retreat stopping cushion, and the circumference of the retreat stopping cushion is provided with more than two notches; an inwards convex groove pole matched with the notches on the retreat stopping cushion is arranged on the inner wall on the circumference of the cup-shaped protective cover, and the bottom of the cup-shaped protective cover is fixedly provided with a reverse screw bolt post.
Description
The antitheft subassembly of lock bolt of the utility model cup-shaped relates to fastening piece, particularly a kind of fastening bolt assembly of using that possesses antitheft and anti-loosening property simultaneously.
Existing NBS bolt does not all possess theftproof performance, need add binding nut when locking, and present anti-theft bolt has following several types:
1, changes the geometrical shape of bolt and nut or increase by an additional protection cap, use general tool to dismantle.Its shortcoming also needs special tool when being assembling, and theftproof performance is bad, and does not possess locking functions.
2, squeeze into pin at the intersection fluting (hole) of bolts and nuts, it can not be rotated with the outside destroy screw thread.Its shortcoming is that the stress surface of bolt reduces, and has reduced the bearing capacity of bolt, and anticorrosive coat is destroyed, and antiseptic property reduces, and can not be fastening again.
3, oblique notch on bolt or nut and insert the axis of rolling, the frictional force when utilizing counter-rotating makes axis of rolling rolling self-locking.Its shortcoming is that the stress surface of bolt reduces, and has reduced the bearing capacity of bolt, and efficient is not high, and the axis of rolling easily comes off.
The purpose of this utility model is exactly the deficiency and the defective that will overcome above-mentioned bolt fastener, and a kind of stress surface that does not destroy bolt and easy to use is provided, and possesses the structure of the antitheft subassembly of lock bolt of cup-shaped of antitheft and anti-loosening property simultaneously.
The purpose of the antitheft subassembly of lock bolt of cup-shaped realizes by following proposal: a kind of cup-shaped bolt assembly includes right-and-left screw, standard nut, retaining pad and cup-shaped protective housing, on the bolt column of right-and-left screw, be vertically arranged with two above locking troughs, bolt column top at right-and-left screw, inside fire attack has an oppositely silk hole, at the standard nut lower end suit retaining pad of spinning on right-and-left screw, on retaining pad, be fixed with the retaining spring sheet, be provided with two with upper notch at the retaining pad periphery, cup-shaped protective housing periphery inwall is provided with the interior tongue post that matches with the retaining pad upper notch, is set with a reverse bolt column in cup-shaped protective housing bottom.
The antitheft subassembly of lock bolt of cup-shaped is to move back button by retaining spring sheet on the retaining pad and the combined restriction tightening nut of the locking trough derotation on the bolt column to realize loosening effect, by retaining pad and cup-shaped protective housing make up realize antitheft, loosen effect, its major advantage is:
1, do not destroy bolt strained, can directly replace equal specification and other plain bolt of level;
2, available heat is zinc-plated etc., and method is carried out preservative treatment, does not also destroy anticorrosive coat after the assembling, and is identical with the antiseptic property of common standard bolt;
3, assembling easy construction does not need special tool;
4, the utility model bolt possesses the function of tightening up;
5, after this bolt was used for structural member, cup-shaped protective housing sheltered from the exposed portions serve of nut and bolt, made assembling back neat appearance.
Below in conjunction with accompanying drawing, the utility model and the example are described further:
Fig. 1 is an embodiment's of the utility model a STRUCTURE DECOMPOSITION schematic representation;
Fig. 2 is an embodiment's of the utility model retaining pad and a cup-shaped protective housing assembled state structural representation.
As an embodiment of the present utility model, as Fig. 1～shown in Figure 2, the antitheft subassembly of lock bolt of this cup-shaped includes right-and-left screw 1, standard nut 5, retaining pad 6 and cup-shaped protective housing 9, the structure of right-and-left screw 1 is: in silk hole opposite with peripheral screw thread direction of the top of bolt inside fire attack (as peripheral screw thread is left-handed, then silk hole dextrorotation).On the bolt column 2 of right-and-left screw 1, be vertically arranged with two above locking troughs 3, bolt column 2 tops at right-and-left screw 1, inside fire attack has an oppositely silk hole 4, at the standard nut 5 lower end suit retaining pads 6 of spinning on the bolt column 2 of right-and-left screw 1, on retaining pad 6, be fixed with retaining spring sheet 7, periphery at retaining pad 6 is provided with two with upper notch 8, cup-shaped protective housing 9 peripheral inwalls are provided with the interior tongue post 10 that matches with retaining pad 6 upper notch 8, are set with a reverse bolt column 12 in cup-shaped protective housing 9 bottoms.During use, screw standard nut 5 holding workpieces after, the reverse bolt column 12 on cup-shaped protective housing 9 bottoms that are set with retaining pad 6 that will match with interior tongue post 10 by recess 8 oppositely screws in the reverse silk hole 4 on bolt column 2 tops of right-and-left screws 1.The locking trough 3 that vertically is provided with on the bolt column 2 does not limit retaining pad 6 with cup-shaped protective housing 9 left-hand precessions, when the retaining spring sheet 7 of precession to the retaining pad 6 and standard nut 5 near after, cup-shaped protective housing 9 can not continue left-handed on the one hand, on the other hand because the restriction of 3 pairs of retaining spring sheets 7 of locking trough, cup-shaped protective housing 9 can not dextrorotation moves back to be buckled, and plays locking, antitheft effect.
Consider that the antitheft subassembly of lock bolt of the utility model cup-shaped may be used in field etc. than under the rugged environment, as a kind of preferred embodiment of the present utility model, as shown in Figure 1, be provided with one or more through holes 11 in the bottom of cup-shaped protective housing 9, help draining, ventilate to also making things convenient for this fastening piece is carried out preservative treatment.
For making things convenient for the connection of the utility model fastening piece, suitably strengthen the chamfering of bolt column 2 ends of band locking trough 3, make things convenient for the embedding of retaining pad 6.
The antitheft subassembly of lock bolt of the utility model cup-shaped not needing can be used for the building or the structure of often dismounting.
