Abstract
The utility model relates to a bolt having a rust-proof cap, which is characterized in that an inwards concave part is arranged on the lower edge of a screw head of the bolt; a ring edge is additionally convexly arranged on the periphery of the inwards concave part; a stainless steel ring sleeve tightly coats the screw head; the ring sleeve coats the screw head from the top surface of the screw head to the lower edge of the screw head; the ring sleeve extends from the top surface of the screw head to the inwards concave part; the ring sleeve extends upwards to the top end of the inwards concave part for tightly coating the screw head. The whole body of the bolt exposing outside of the utility model has the advantages of good corrosion resistance and good anti-rust property; the service life of the bolt can be lengthened.
Description
The utility model relates to a kind of bolt, refers to a kind of bolt with antirust cap especially.
General bolt has the function of self tapping screw lock mostly, and can be with the solid locking bit of workpiece; Please cooperate and consult shown in Figure 14ly, be known cross bolt 30 structures, behind these cross bolt 30 locking workpiece 40, its spiral shell head 31 is exposed to the external world (shown in Figure 15,16), very easily, cause screw thread partly to produce corrosion, form whole bolt corrosion indirectly because of the entering of moisture content or air, whole support bolt can't be moved by spiral shell, if the power that unscrews is too quickly, the possibility of bolt fracture is then probably arranged, thus, whole utensil is just scrapped thereupon, and is very unfortunate; Moreover, please cooperate and consult shown in Figure 17,18, more there is the user to make the screw thread of bolt 50 can press close to the article of screw lock more closely, the effect of screw lock is more strengthened, so simultaneously at screw lock, a sheathed soft balsam ring 60 in addition on bolt, bolt 50 more fits tightly workpiece 40 in the time of can making screw lock, so, so increase glue ring 60, the compressing power in the time of also can be because of screw lock causes whole glue ring 60 to break or produces improper displacement, and takes a broad view of above-mentioned disadvantages, so do further improvement at bolt arrangement, its necessity arranged in fact.
The purpose of this utility model is to provide a kind of bolt with antirust cap, and order is exposed to extraneous bolt integral body can have preferable corrosion resistance and rust protection, prolongs the working life of bolt.
The utility model provides a kind of bolt with antirust cap, it is characterized in that: the spiral shell head lower edge in bolt is provided with an inner fovea part, and the inner fovea part periphery is convexly equipped with out a ring edge in addition, closely be coated with a stainless steel ring set on this spiral shell head, this ring set is covered to the lower edge of spiral shell head by spiral shell crown bread, and this ring set extends to this inner fovea part by spiral shell crown face, and up closely coats the spiral shell head to the top of inner fovea part.
Described bolt with antirust cap is characterized in that: the spiral shell head of this bolt can be the outer-hexagonal shape.
Described bolt with antirust cap is characterized in that: the spiral shell head of this bolt also can be interior hexagonal shape.
Described bolt with antirust cap is characterized in that: the spiral shell head of this bolt can have the cross grooving.
Described bolt with antirust cap is characterized in that: spiral shell head outer rim can be provided with one for the solid plane edge of magnetic spiral shell.
Bolt with antirust cap of the present utility model has following advantage:
1, has splendid rust protection:, be exposed to extraneous bolt integral body and can have preferable corrosion resistance and rust protection, and the value of bolt integral body is greatly improved owing to closely coat the stainless steel ring set on the spiral shell head of bolt.
2, cooperate the locking rubber cushion effectively to locate: because of bolt is provided with inner fovea part, if the user carries out solid lock with rubber cushion again, can make this rubber cushion definitely be positioned in this inner fovea part, though and this rubber cushion is oppressed, but still can definitely be positioned wherein, be no gap state after making bolt and the workpiece locking combining, can definitely stop moisture content to enter wherein, and the rust-proof effect of integral body is more greatly increased.
In order further to understand, below to lift a preferred embodiment now, and cooperate diagram that structure of the utility model and the effect of being reached thereof are described in detail as the back the utility model:
The simple declaration of accompanying drawing drawing:
Fig. 1 is the three-dimensional exploded view of the utility model.
Fig. 2 is the three-dimensional combination figure of the utility model.
Fig. 3 is the combination section of the utility model.
Fig. 4 is the schematic top plan view of the utility model.
Fig. 5 is the installing generalized section of the utility model.
Fig. 6 is the combination section of the utility model.
Fig. 7 is the combination section of the utility model.
Fig. 8 is another three-dimensional combination figure of the utility model.
Fig. 9 is the combination section of Fig. 8.
Figure 10 is the schematic top plan view of Fig. 8.
Figure 11 is the another three-dimensional combination figure of the utility model.
Figure 12 is the combination section of Figure 11.
Figure 13 is the schematic top plan view of Figure 11.
Figure 14 is for commonly using the stereo appearance figure of bolt.
Figure 15 is the combination section of Figure 14.
Figure 16 is the schematic top plan view of Figure 14.
Figure 17 is for commonly using another schematic appearance of bolt.
Figure 18 is the schematic top plan view of Figure 17.
Seeing also Figure 1 and Figure 2, is the three-dimensional exploded view and the three-dimensional combination figure of the utility model, and the bolt with antirust cap is to coat a stainless steel ring set 20 on bolt 10, makes bolt integral body obtain preferable rust protection.
See also shown in Figure 8, another three-dimensional combination figure for the utility model, the spiral shell head 11 of this bolt 10 is to be the outer-hexagonal shape, and it is directly closely to be coated to the root edge of spiral shell head 11 by end face with a ring set 20, and can have preferable antirust function (please cooperate and consult 9 figure and shown in Figure 10); Moreover, please continue to cooperate and consult shown in Figure 11ly, the spiral shell head 11 of this bolt 10 also can be interior hexagonal shape, and is directly closely coated to the root edge of spiral shell head 11 by end face with a ring set 20, also can have preferable antirust function (please cooperate and consult shown in Figure 12,13).
In sum, the utlity model has the bolt of antirust cap, have splendid antirust function, and can tightr coating spiral shell head, the value of bolt integral body can greatly be improved.
