Abstract
The utility model relates to a cup cover-shaped anti-theft and anti-loosing component part of a screw bolt, relating to a fastener. The cup cover-shaped anti-theft and anti-loosing component part of a screw bolt comprises the screw bolt, a retaining nut, a retreat stopping cushion, and a cup-shaped protective cover, wherein, the reverse loosening of the retaining nut is limited by a retreat stopping piece of the retreat stopping cushion on one hand, and the cup-shaped protective cover is limited to be capable of screwing in a single direction without retreating reversely by the retreat stopping piece of the retreat stopping cushion on the other hand; the fastener and a screw bolt post are also coated inside by the cup-shaped protective cover. The anti-theft and anti-loosing functions are played.
Description
The antitheft subassembly of lock bolt of 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.It also needs special tool when really point is 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 the antitheft subassembly of lock bolt of cup-shaped 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 bolt fastener 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 fastener includes trough of belt bolt, standard nut, retaining pad and cup-shaped protective housing, on bolt column, be vertically arranged with one or more locking trough, at the standard nut lower end suit retaining pad of spinning on the trough of belt bolt column, 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 fixed with a nut 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 locking effect, make up by retaining pad and cup-shaped protective housing and to realize antitheft, locking 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 nut, made assembling back neat appearance.
Below in conjunction with accompanying drawing, the utility model and the example are described further:
Fig. 1 is embodiment's retaining pad of the utility model and cup-shaped protective housing assembled state structural representation;
Fig. 2 is an embodiment's of the utility model a STRUCTURE DECOMPOSITION stereogram.
As an embodiment of the present utility model, as shown in Figure 2, the antitheft subassembly of lock bolt of this cup-shaped includes trough of belt bolt 1, standard nut 4, retaining pad 6, cup-shaped protective housing 8, on the bolt column 2 of trough of belt bolt 1, be vertically arranged with one or more locking trough 3, at the standard nut 4 lower end suit retaining pads 6 of spinning on the bolt column 2 of trough of belt bolt 1, on retaining pad 6, be fixed with retaining spring sheet 5, periphery at retaining pad 6 is provided with two with upper notch 7, cup-shaped protective housing 8 peripheral inwalls are provided with the interior tongue post 10 that matches with retaining pad 6 upper notch 7, are provided with a nut 11 in cup-shaped protective housing 8 bottoms.After screwing standard nut 4 holding workpieces during use, nut 11 on cup-shaped protective housing 8 bottoms that are set with retaining pad 6 that will match with interior tongue post 10 by recess 7 screws on the bolt column 2 of trough of belt bolts 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 8 precessions, when the retaining spring sheet 5 of precession to the retaining pad 6 and standard nut 4 near after, cup-shaped protective housing 8 can not continue precession on the one hand, on the other hand because the restriction of 3 pairs of retaining spring sheets 5 of locking trough, cup-shaped protective housing 8 can not derotation 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 5, be provided with one or more through holes 9 in the bottom of cup-shaped protective housing 8, 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 cover not needing can be used for the building or the structure of often dismounting.
