Abstract
The utility model discloses the rotating screw of a kind of head, comprise screw, nut, screw head-shield, threaded collar, screw is made up of screw head and screw rod two-part, and head central authorities offer groove and multiple intervals draw-in groove is set; Nut head central authorities arrange polygon groove, and pane arranges multiple tangs; Described screw head-shield top arranges U-shaped notch, and interior arranges screw thread, and screw head-shield central authorities offer hole, and lower inside surface is provided with screw thread; Nut head-shield bottom can be connected with threaded collar; Described screw, nut, screw head-shield and threaded collar are separate, and the head that nut can be placed on screw connects by draw-in groove, and threaded collar penetrates with screw head-shield and is threaded connection from screw bottom.The utlity model has following advantage: screw cap can rotate, screw Whole-dismountable, screw head is not easy filigree, is easy to manufacture.
Description
Technical field
The utility model relates to mechanical field, more specifically to the rotating screw of a kind of head.
Background technique
At mechanical field, screw is as the connector of some members, effect obviously, the most of head of screw on market is fixed now, needing screw that head can be movable to connect existing screw for some device can not meet, after other screw is arranged on some interior of articles, the time has been grown easy corrosion, and the polygonal groove of screw head is the easy filigree of head polygonal in the time twisting with screw-driver, causes screw to lay down.
Summary of the invention
The purpose of this utility model is to provide a kind of head rotating screw, adopts this screw, can make up prior art deficiency.For achieving the above object, the utility model has adopted following technological scheme:
The rotating screw of a kind of head, comprises screw, nut, screw head-shield, threaded collar, and described screw is made up of screw head and screw rod two-part, and screw head is arranged to hemispherical, and head central authorities offer groove and multiple intervals draw-in groove is set; Described nut head central authorities arrange polygon groove, and pane arranges multiple tangs; Described screw head-shield top arranges U-shaped notch, and interior arranges screw thread, and screw head-shield central authorities offer hole, and lower inside surface is provided with screw thread; Described nut head-shield bottom can be connected with threaded collar; Described screw, nut, screw head-shield and threaded collar are separate, and the head that nut can be placed on screw connects by draw-in groove, and threaded collar penetrates with screw head-shield and is threaded connection from screw bottom.
Described screw head-shield lower inside screw thread and threaded collar outside screw are coupled.
In the middle of described screw head-shield, perforate aperture is less than nut outer diameter, is greater than nut central authorities polygon groove diameter.
Described threaded collar inner diameter is greater than screw diameter, is less than screw head upper diameter.
The utlity model has following advantage: screw cap can rotate, screw Whole-dismountable, screw head is not easy filigree, is easy to manufacture.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1, screw thread; 2, screw head-shield; 3, polygon groove; 4, nut; 5, tang; 6, draw-in groove; 7, screw head; 8, screw rod; 9, threaded collar.
Embodiment
With the drawings and specific embodiments, the utility model is described in further detail below.
As shown in the figure, the rotating screw of a kind of head, comprises screw, nut 4, screw head-shield 2, threaded collar 9, and described screw is made up of screw head 7 and screw rod 8 two-part, and screw head 7 is arranged to hemispherical, and head central authorities offer groove and multiple intervals draw-in groove 6 is set; Described nut 4 head central authorities arrange polygon groove 3, and nut 4 sides arrange multiple tangs 5; Described screw head-shield 2 tops arrange U-shaped notch, and interior arranges screw thread 1, and screw head-shield 2 central authorities offer hole, and lower inside surface is provided with screw thread; Described nut head-shield 2 bottoms can be connected with threaded collar 9; Described screw, nut 4, screw head-shield 2 and threaded collar 9 are separate, and the head that nut 4 can be placed on screw connects by draw-in groove 6, and threaded collar 9 penetrates with screw head-shield 2 and is threaded connection from screw bottom.
Described screw head-shield 2 lower inside screw threads and threaded collar 9 outside screw are coupled.
In the middle of described screw head-shield 2, perforate aperture is less than nut 4 outer diameters, is greater than central polygon groove 3 diameters of nut 4.
Described threaded collar 9 inner diameters are greater than screw rod 8 diameters, are less than screw head 7 upper diameter.
When use, screw head-shield can be connected with other objects, screw head-shield top is connected with threaded collar, nut and screw head are in screw head-shield inside, and screw head-shield is rotatable, in the time that screw is installed, available screw-driver is twisted nut through the hole in screw head-shield, owing to fixing by draw-in groove between nut and screw head, so sieve cap can not rotate, in the process of twisting nut, hand can be held screw head-shield and ensure screw balance; In the time that needs unload screw, there is filigree phenomenon in the polygon groove of weak nut central authorities, can, by screw cover and threaded collar dismounting, take out nut, and using steel pole to be directly stuck in to turn in the draw-in groove of screw can be by screw disassembling.
Claims (4)
1. the rotating screw of head, comprises screw, nut, screw head-shield, threaded collar, it is characterized in that, described screw is made up of screw head and screw rod two-part, and screw head is arranged to hemispherical, and head central authorities offer groove and multiple intervals draw-in groove is set; Described nut head central authorities arrange polygon groove, and pane arranges multiple tangs; Described screw head-shield top arranges U-shaped notch, and interior arranges screw thread, and screw head-shield central authorities offer hole, and lower inside surface is provided with screw thread; Described nut head-shield bottom can be connected with threaded collar; Described screw, nut, screw head-shield and threaded collar are separate, and the head that nut can be placed on screw connects by draw-in groove, and threaded collar penetrates with screw head-shield and is threaded connection from screw bottom.
