Abstract
The utility model discloses a kind of screw, comprise screw rod, described screw rod is provided with eccentric hexagon nut, driving washer is provided with between described eccentric hexagon nut and described screw rod, described eccentric hexagon nut is connected with described screw rod by described driving washer, and described eccentric hexagon nut is provided with the locking nut matched with described screw rod.The beneficial effects of the utility model: screw described in the utility model structurally improves, make the fixed effect of screw better, and can not expand with heat and contract with cold because of external environment condition, anti-loosing effect is better.
Description
Technical field
The utility model relates to mechanical fitting technical field, specifically, relates to a kind of screw.
Background technique
As everyone knows, screw is absolutely necessary in mechanical engineering, and the quality of screw also affects the Security of machinery, at present, screw on the market all needs to add pad to reach anti-loosing effect, but the effect that pad can be expanded with heat and contract with cold, and anti-loosing effect needs to be considered.
So, develop the screw that a kind of anti-loosing effect is good, ensure the Security of machinery, become the problem that Professional visitors needs solution badly.
Model utility content
For the above-mentioned technical problem in correlation technique, the utility model proposes a kind of screw, by the cooperation of pad, locking effect can not be reached.
For realizing above-mentioned technical purpose, the technical solution of the utility model is achieved in that
A kind of screw, comprise screw rod, described screw rod is provided with eccentric hexagon nut, driving washer is provided with between described eccentric hexagon nut and described screw rod, described eccentric hexagon nut is connected with described screw rod by described driving washer, and described eccentric hexagon nut is provided with the locking nut matched with described screw rod.
Further, the shape of described eccentric hexagon nut upper end is eccentric round platform shape.
The beneficial effects of the utility model: the screw described in the application structurally improves, make the fixed effect of screw better, and can not expand with heat and contract with cold because of external environment condition, anti-loosing effect is better.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the screw according to the utility model embodiment.
In figure:
1, screw rod; 2, driving washer; 3, eccentric hexagon nut; 4, locking nut.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain, belongs to the scope of the utility model protection.
As shown in Figure 1, a kind of screw according to the utility model embodiment, comprise screw rod 1, described screw rod 1 is provided with eccentric hexagon nut 3, driving washer 2 is provided with between described eccentric hexagon nut and described screw rod, described eccentric hexagon nut 3 is connected with described screw rod 1 by described driving washer 2, and described eccentric hexagon nut 3 is provided with the locking nut 4 matched with described screw rod 1.
In one embodiment, the shape of described eccentric hexagon nut 3 upper end is eccentric round platform shape.
Conveniently understand technique scheme of the present utility model, below by way of in concrete usage mode, technique scheme of the present utility model is described in detail.
When specifically using, according to screw described in the utility model, screw rod and eccentric hexagon nut being fixed by driving washer 2 and is connected; Or, described eccentric hexagon nut 3 adds locking nut 4, thus increases tightness.
In sum, by means of technique scheme of the present utility model, by structurally being improved by existing screw, make the fixed effect of screw better, and can not expand with heat and contract with cold because of external environment condition, anti-loosing effect is better.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
