Abstract
The utility model discloses an anti-loosening cover for a nut under a surface. The anti-loosening cover comprises a nut sleeve retainer, wherein the lower part of the nut sleeve retainer is provided with a bolt hole, the top of the nut sleeve retainer extends outwards to form a circular disc, a plurality of screw holes are formed in one circle of the edge of the circular disc, and a fixing bolt is in threaded connection to each screw hole. The anti-loosening cover disclosed by the utility model is simple in structure, good in anti-loosening effect and very suitable for a working environment in which the nut is under the surface and the vibration is violent.
Description
Technical field
The utility model relates to a kind of screw-nut technical field, particularly a kind of Anti-loosing-cover for surperficial lower nut.
Background technique
Traditional nut anti-looseness method is divided into two large classes substantially, and a class is that friction is locking, and another kind of is that machinery is locking.The locking class methods of rubbing the inside comprise to decide nut anti-looseness, spring washer is locking and self-locking nut is locking etc.; The locking class methods of machinery the inside comprises again that cotter pin is locking with hexagon slotted nut, lock washer is locking, the steel wire of connecting is locking etc.
Also have some more special anti-loose methods, as screw between screw thread and inlay nylon ring with liquid adhesive or nut end.In addition, it is locking to also have riveting to rush method, the bolt end is rivetted or bolts and nuts revolve commissure and play punching.This several method is reliable, but not quick detachable, and coupling can not continue to use after the dismounting.
But these above-mentioned methods all are not suitable for nut under the surface and vibrations are relatively more severe, locking demanding working environment, and main cause is that subsurface space is very little, mounting or dismounting are all inconvenient.
The model utility content
Goal of the invention of the present utility model is: for the problem of above-mentioned existence, provide a kind of Anti-loosing-cover for surperficial lower nut.
The technical solution adopted in the utility model is such: a kind of Anti-loosing-cover for surperficial lower nut, comprise the nut anti-looseness sleeve, this nut anti-looseness lower cartridge is established bolt hole, outwards extend and form a disk in the top, this disk border one circle offers some screws, and the screw internal thread is connected and fixed bolt.
As preferably, the bolt hole of described nut anti-looseness lower cartridge is the regular hexagon hole.
As preferably, the screw on the described nut anti-looseness sleeve top disc has two, and the line between two screws passes through circle disk center.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are: simple in structure, anti-loosing effect good, be very suitable for nut under the surface and the stronger working environment of vibration.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 embodiment's plan view.
Mark among the figure: 1 is the nut anti-looseness sleeve, and 2 is workpiece, and 3 is nut, and 4 is fixing bolt.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
Embodiment 1: a kind of Anti-loosing-cover for surperficial lower nut, comprise nut anti-looseness sleeve 1, bolt hole is established in this nut anti-looseness sleeve 1 bottom, outwards extend and form a disk in the top, this disk border one circle offers two screws, line between two screws is by circle disk center, and the screw internal thread is connected and fixed bolt 4.
Embodiment 2: as shown in Figure 1, 2, a kind of Anti-loosing-cover for surperficial lower nut, comprise nut anti-looseness sleeve 1, bolt hole is established in this nut anti-looseness sleeve 1 bottom, outwards extend and form a disk in the top, this disk border one circle offers two screws, and the line between two screws is by circle disk center, and the screw internal thread is connected and fixed bolt 4.In the present embodiment, the bolt hole of described nut anti-looseness sleeve 1 bottom is the regular hexagon hole.
During use, first the lower connection part in workpiece 2 surfaces among Fig. 1 is locked with the bolt connection and with nut 3, then the bolt hole with nut anti-looseness sleeve 1 of the present utility model entangles nut 3, the disk at nut anti-looseness sleeve 1 top is close to workpiece surface, then, the screw that screws on the disk with bolt 4 also further screws in the workpiece 2, and the utility model is fixed on the workpiece 2.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
