Abstract
The utility model relates to a screw and screw cap structure which can form a position tenon and cave, particularly the screw and the screw cap used for locking and fixing thin sheet, wherein, a neck between the head of the screw and a screw part is designed to an oblique cone. A cone cavity which in a wedge matching with the oblique cone is arranged on the screw opening of the screw cap; when the thin sheet is tightly clamped between the screw and the screw cap, the thin sheet can form a positioning structure with a convex shoot and a recess, following the cone cavity and the oblique cone of a convex block.
Description
The utility model relates to the structure of a kind of screw, nut, is meant especially to form location bamboo shoot, the screw in cave, the structure of nut.
Screw nut only is a kind of part of fastening usefulness during the parts combination, usually two parts that locked boring in addition during if any the important relevance of relative position, plug locating stud, stable to strengthen combination back parts binding site, when taking reorganization apart, also promptly replied original bonding state backward.Combination for light sheet, what use rivet or welding all is must not separate after the combination of two parts again, and as will be with screw, when nut is sealed, then can also take reorganization again apart, but need in position to establish in addition locating stud, otherwise must check the position again one time when being exactly each the refitting, check and approve playback.
The purpose of this utility model provides a kind of screw nut structure that forms location bamboo shoot, cave, when screw nut combination lock for thin plate class material, can form location bamboo shoot, cave simultaneously, sideslip when preventing that sheet material is stressed, and help to dismantle when recombinating, keep in the center rapidly.
The technical solution of the utility model is: it comprises a screw and nut, wherein the head of screw and the neck between the screw section are arranged to oblique cone, and be provided with and the oblique cone awl cave of wedging mutually at the opening end of the interior threaded hole of nut, when using this screw, because the effect in oblique cone cave the is pressed from both sides sheet material effect that the superimposed bamboo shoot of one group of taper of formation and cave play the location of pulling with nut locker two thin plates.
This structure also can be in addition: wherein the lower head of screw is provided with the ring-type bamboo shoot of protrusion, and is provided with the relatively slightly depression of wedging in the last plane of nut, and the cooperation in bamboo shoot, cave folder is pulled and made extruding form superimposed ring-type bamboo shoot, a cave on two sheet materials whereby.
This structure also can be: awl cave wherein and ring cave are arranged on the screw terminal bottom surface, and oblique cone and ring bamboo shoot are to be located on the nut plane.
Below in conjunction with drawings and Examples the utility model being done one specifies.

Fig. 2 is the sealed front construction figure of the utility model embodiment's sheet material;
Fig. 3 is the sealed back of the utility model embodiment's a sheet material tectonic maps;
Fig. 4 is the utility model embodiment's sheet material forming figure;
Fig. 5 is a reorganization automatic homing schematic representation behind the utility model embodiment's the sheet material forming;
Fig. 6 is that the utility model is implemented the second routine structural drawing;
Fig. 7 is the sheet material forming figure that the utility model is implemented second example;
Fig. 8 is that the utility model is implemented the 3rd routine structural drawing;
Fig. 9 is that the utility model is implemented the 4th routine structural drawing.
As shown in Figure 1, wherein screw has a head (13), a spire (12), and the neck between head and spire (11) is arranged to oblique cone shape, is called oblique cone (11); Nut (2) is at its spiral (22) opening, establish one with oblique cone (11) the awl cave (21) of wedging mutually.
As shown in Figure 2, the situation of this kind screw (1) nut (2) when the locking light sheet, establish a screw that aligns (A3) on two sheet materials (A), (B) (B3), the spire (12) of screw (1) passes screw, be locked together on the nut (2), awl cave (21) on this nut (2) is relative with the oblique cone (11) of screw (1) towards sheet material, after brute force is fastening, borrow awl cave (21) and the oblique cone (11) can be, wherein (B) the concavo-convex bamboo shoot that are superimposed together of formation respectively of sheet material (A) with (B) the crowded state that becomes as shown in Figure 3 of sheet material (A); Referring to Fig. 4, the protruding bamboo shoot (A1) of sheet material (A) are embedded in the depression (B2) of sheet material (B) just fully; Because the formation in the concavo-convex bamboo shoot cave of these wedgings can very promptly slide onto the location, as shown in Figure 5 when two sheet materials (A) are (B) superimposed again.
Above-mentioned screw, the relative oblique cone of nut can also be as shown in Figure 6 with the application in awl cave, on screw (3) head bottom surface, establish the ring bamboo shoot (31) of protrusion, and the ring cave (41) of on nut (4), establishing the phase wedging, can make sheet material form superimposed concavo-convex ring bamboo shoot when making both clampping plate materials (C) (D), as shown in Figure 7, therefore can reach on-slip, the easy effect that returns the location equally.
Aforesaid oblique cone, awl cave, ring bamboo shoot, ring cave etc. are arranged again, and cave (51), oblique cone (61), ring cave (71), ring bamboo shoot (81) etc. are promptly bored in general reverse setting shown in Fig. 8 and 9, can reach the bamboo shoot cave, location on the automatic formation sheet material equally.
Good effect of the present utility model is to do the bamboo shoot structure setting of the concavo-convex cave of relative wedging at screw nut in sum, make it when the locking light sheet, except the effect that reaches " axially " locking, make simultaneously sheet material have the effect of " radially " location, therefore can exempt the setting of alignment pin, have again the effect of automatic tracking playback. Equally, when screw, nut lock for light sheet, can form simultaneously bamboo shoot cave, location, break away when preventing that sheet material is stressed, and the advantage of keeping in the center rapidly when helping to dismantle restructuring.
Claims (3)
1, a kind of screw nut structure that forms location bamboo shoot, cave, it comprises head (13), spire (12) and the nut (2) of screw (1), screw, it is characterized in that the neck between head (13) and spire (12) is arranged to oblique cone (11); Spiral (22) opening of nut (2) establish one with oblique cone (11) the awl cave (21) of wedging mutually.
2, screw nut structure as claimed in claim 1 is characterized in that wherein the lower head of screw (1) is provided with the ring bamboo shoot (31) of protrusion, and is provided with the ring cave (41) of relative wedging in the last plane of nut (4).
