Abstract
A device capable of preventing a nut from loosening comprises a fixing end and a limiting end. The fixing end is of a hollow circular truncated cone structure. The limiting end is of a hollow circular pipe structure. A limiting face capable of preventing the nut from rotating is arranged in an inner cavity of a hollow circular pipe. The device capable of preventing the nut from loosening is simple in structure, convenient to machine, low in use cost, convenient to install and detach and capable of being widely applied to threaded connection of various mechanical devices.
Description
Technical field
The present invention relates to fastening piece mounting technique field, particularly there is loosening device in a kind of nut preventing installing.
Background technique
Often fastening piece can be used in mechanical erection process; one of advantage that fastening piece is connected compared with other by scyewed joint is that it is detachable, easy-maintaining; but this is also its weakness simultaneously; particularly running up, vibrating in the heavy mechanical equipments such as strong train, automobile, aircraft and tank, because of the loosening of scyewed joint, get loose and fatigue fracture etc. and cause overturning, fatal crass malignant event innumerable.Along with machinery at a high speed, precise treatment development, commercial scale is to the development etc. of extensive, automation development and aerospace engineering, and the locking problem that threaded fastener connects also becomes more and more outstanding.The conventional anti-loose method of nut mainly contains three kinds: rub locking, mechanical locking and forever locking.The method of usual employing utilizes pad, self-locking nut and double nut etc., often adopts in this way that anti-loosing effect is not obvious, or there is the higher problem of user cost; Or utilizing cotter pin, locked spacer and string wire rope etc., this mode is often installed cumbersome, installs, removal efficiency is lower; Or adopt spot welding, riveted joint and bonding etc., and adopt and mostly will destroy threaded fastener when dismantling in this way, cause fastening piece to reuse.
Summary of the invention
The invention solves above technical problem, provide a kind of structure simple, there is the device loosened in a kind of nut that can effectively prevent of installation, convenient disassembly.
For solving the problems of the technologies described above, present invention employs following technological scheme:
Can prevent the device of nut loosening, comprise fixed end and positive stop end, described fixed end is open circles frustum structure, and described positive stop end is hollow circular-tube structure, and described hollow circular-tube inner chamber is provided with the confined planes that can prevent nut from rotating.
Further, described hollow circular-tube inner chamber is square or regular hexagon.
Further, described fixed end and positive stop end are monolithic construction.
The beneficial effect that the present invention has:
1), structure is comparatively simple, and processing is got up also more for convenience, and can be obtained by casting, welding or the mode of directly processing, user cost is lower;
2), install, convenient disassembly, the labor intensity of operation can be alleviated, raise the efficiency, can be widely used in the scyewed joint of various machinery.
Accompanying drawing explanation
Fig. 1 is scheme of installation of the present invention.
Fig. 2 is structural front view of the present invention.
Fig. 3 is structure plan view of the present invention.
In figure, 1, the device of nut loosening can be prevented; 2, mounting nuts; 3, tightening nut; 4, bolt; 5, connected piece; 11, fixed end; 12, positive stop end; 13, cavity; 14, confined planes.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
With reference to Fig. 1, for a kind of device preventing nut loosening, comprise fixed end 11 and positive stop end 12, described fixed end 11 is open circles frustum structure, described positive stop end 12 is hollow circular-tube structure, and described hollow circular-tube inner chamber 13 is provided with the confined planes 14 that can prevent nut from rotating.
In the present invention, described hollow circular-tube inner chamber 13 is square or regular hexagon, and the nut of respective model can just block by square or regular hexagon cavity 13, is used for preventing the rotation of nut.
In the present invention, described fixed end 11 and positive stop end 12 are monolithic construction.
Use installation process of the present invention as follows: to connect connected piece 5 with bolt 4, mounting nuts 2 is arranged on bolt 4, then this device 1 is arranged on mounting nuts 2, by the confined planes 14 on this device 1, the rotation of mounting nuts 2 can be limited, finally tightening nut 3 is arranged on bolt 4, and this device 1 is compressed.
Claims (3)
1. can prevent the device of nut loosening, it is characterized in that: comprise fixed end and positive stop end, described fixed end is open circles frustum structure, and described positive stop end is hollow circular-tube structure, and described hollow circular-tube inner chamber is provided with the confined planes that can prevent nut from rotating.
2. the device preventing nut loosening according to claim 1, is characterized in that: described hollow circular-tube inner chamber is square or regular hexagon.
