Abstract
The utility model discloses a kind of screw, the locking active ring comprising hexagon nut and coordinate with described hexagon nut, check washer is established between described hexagon nut and described locking active ring, and, described hexagon nut is also provided with the dust cover coordinated with described hexagon nut.The beneficial effects of the utility model: by dust cover and check washer with the use of, life-span can improving screw to a great extent be connected fastening performance, for engineering safety provides good guarantee.
Description
Technical field
The utility model relates to mechanical parts, specifically, relates to a kind of screw.
Background technique
In mechanical field, screw is common, indispensable connection class strength member, existing screw is all port, such as at vehicle in the process of moving, when running into bad vehicle condition, screw port inevitably can be stained with sandy soil or other materials, like this will working life shortening screw greatly in degree, moreover, as connection class part, the fastening effect of screw is also worth interest.
So, develop the screw that a kind of life-span is long, tightness is superior, just 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 nut, there is good working life and anti-loosing effect.
For realizing above-mentioned technical purpose, the technical solution of the utility model is achieved in that
A kind of screw, the locking active ring comprising hexagon nut and coordinate with described hexagon nut, establishes check washer between described hexagon nut and described locking active ring, and, described hexagon nut is also provided with the dust cover coordinated with described hexagon nut.
Further, described locking active ring is connected with screw-thread fit between described hexagon nut.
Further, between described dust cover with described hexagon nut, screw-thread fit is connected.
The beneficial effects of the utility model: by dust cover and check washer with the use of, life-span can improving screw to a great extent be connected fastening performance, for engineering safety provides good guarantee.
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, dust cover; 2, hexagon nut; 3, check washer; 4, locking active ring.
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, the locking active ring 4 comprising hexagon nut 2 and coordinate with described hexagon nut 2, check washer 3 is established between described hexagon nut 2 and described locking active ring 4, further, described hexagon nut 2 is also provided with the dust cover 1 coordinated with described hexagon nut 2.
In one embodiment, between described relaxation exercise circle 4 with described hexagon nut 2, screw-thread fit is connected.
In one embodiment, between described dust cover 1 with described hexagon nut 2, screw-thread fit is connected.
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, dust cover 1 covers after connecting by screw, can greatly reduce dust in using process, the falling into of impurity, and improves the life-span used; Further, in use, check washer 3 can improve the tightness of screw greatly, ensures the safety of construction quality.
In sum, by means of technique scheme of the present utility model, by dust cover 1 and check washer 3 with the use of, life-span can improving screw to a great extent be connected fastening performance, for engineering safety provides good guarantee.
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.
