Summary of the invention
In order to solve the problem of above-mentioned existence, the utility model discloses the smooth desirable screw of a kind of end cap, end cap is smooth, can take off replacing, and after making screw be fixed on object, end cap is smooth, can not hook bad clothes or other things, also prevents corrosion.
The smooth desirable screw of end cap, comprise head and screw rod, described head is provided with detachable end, the top of end cap is the smooth circular shape that arches upward, the surrounding of end cap is provided with the collar that adds towards interior curve, adding collar has contraction elasticity, and end cap increases towards top thickness gradually from the surrounding bottom, and the inside center of end cap forms the vacancy mouth of a flat circular.
Described end cap increases towards top hardness gradually from surrounding.
The surrounding of described head is provided with groove, and adding collar can be stuck in groove.
Describedly add collar and can be stretched, wrap in the head surrounding, with head, fix.
Described end cap can add collar and takes off from the head by pulling.
On the end face of described head, be provided with cross bore.
On the end face of described head, be provided with plum blossom hole.
The end of described screw rod is pointed.
The utility model, simple in structure, easy to use, be widely used, avoid rub outside people or hook bad other things of head exposure, play a very good protection, screw-driving is fixed on body surface, and end cap can also play effect attractive in appearance.When this screw uses, at first end cap separates with the head of screw, with cross like spanner or plum blossom shaped spanner, reach in cross bore or plum blossom hole, screw rod is screwed in the object that is connected fully, takes cross like spanner or plum blossom shaped spanner away, end cap is enclosed within to screw head, encase screw head fully, end cover surface is smooth, and attractive in appearance, can not hook and go bad anything.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Reference numerals list: 1-head, 2-groove, 3-vacancy mouth, 4-end cap, 5-cross bore, 6-add collar, 7-screw rod.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.Should understand following embodiment and only be used to the utility model is described, be not used in restriction scope of the present utility model.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, word " interior " and " outward " refer to respectively towards or away from the direction of specific features geometrical center.
Fig. 1 is structural representation of the present utility model, as we can see from the figure, the smooth desirable screw of this end cap, comprise head 1 and screw rod 7, described head 1 is provided with detachable end 4, and the top of end cap 4 is the smooth circular shape that arches upward, the surrounding of end cap 4 is provided with and adds collar 6 towards interior curve, adding collar 6 has contraction elasticity, and end cap 4 increases towards top thickness gradually from the surrounding bottom, and the inside center of end cap 4 forms the vacancy mouth 3 of a flat circular.The utility model; head 1 is used for being connected with spanner; give screw rod 7 reinforcings; its rotation is screwed in the middle of the two articles that is connected; the screw thread on screw rod 7 surfaces is fixed on screw in the middle of object; end cap 4 plays a protective role; avoid head hurt the people or hook bastard, after screw is fixed in object, the collar that adds of end cap 4 is strutted; be set to the outside of head 1; after unclamping, add collar and shrink, be fixed on head 1; in end cap, 4 discoid vacancy mouths 3 of middle flat just can be stuck in head 1 wherein fully, strengthen fixation.
Described end cap 4 increases towards top hardness gradually from surrounding.End cap 4 is from surrounding towards centre, evenly transition smoothly, and thickness increases, and hardness increases, and makes end cap 4 global shapes attractive in appearance, simultaneously, avoids end cap 4 to damage, and extends the working life of end cap.
