2. collar is placed on the fixed base;
3. provide one be provided with vestibule fixed plate, fixed plate is arranged on the said fixed base, push down collar, this moment, fixed plate, collar and fixed base constituted an assembly parts, collar is between fixed plate and fixed base.
4. screw is squeezed into said assembly parts along installation direction, said screw thread passes fixed plate and collar successively, gets into tapped hole and fixes, and this moment, screw was positioned at assembly parts, and collar and fixed plate are limited between boss and the screw head.
Said collar inboard is equipped with shell fragment, and when screw got into assembly parts, shell fragment produced deformation and crosses boss when collar was crossed boss, and shell fragment and boss fasten, and fixed plate is limited between boss and the screw head.
The said collar outside is provided with outer wall, and said fixed base is provided with bulge loop, step 2. in, said outer wall inboard is set in the outside of bulge loop.
When said step is squeezed into assembly parts with screw in 4., earlier screw is inserted assembly parts, then screw thread portion is screwed into tapped hole.
Said fixed plate is provided with convexity, and said convexity is pressed in collar on the fixed base.
Beneficial effect of the present invention: a kind of simple and practical mooring screw and assembly method are provided, have prevented that the screw on the machine part from losing, caused machine breakdown, made whole assembly process easier simultaneously, efficient is higher.The present invention is applicable to and need screw be tethered in the structure on the product.

Embodiment
Below in conjunction with accompanying drawing optimal technical scheme of the present invention is elaborated.
Referring to Fig. 1, shown in the figure mooring screw 10 according to the preferred embodiments of the invention, it comprises screw 1 and collar 2, and said screw 1 comprises the screw head 11 that is arranged on its top, and said screw head 11 is provided with screw-driver slot, and said screw-driver slot is a Hexagon.Said screw 1 bottom is provided with screw thread 12, is screw rod 13 between screw thread 12 and the screw head 11, and said screw rod 13 is provided with boss 131, and it can be limited in collar 2 between boss 131 and the screw head 11.The outer wall of boss 131 to bottom angled, forms inclined-plane 1311 by the top, and said inclined-plane 1311 play the guiding role when collar 2 snaps in boss 131, makes collar 2 cross boss 131 more easily.Said mooring screw 10 also comprises bullet pad 3, and said bullet pad 3 roughly circularizes, and ring is provided with opening, and bullet pad 3 can slide on the screw rod 13 between boss 131 and the screw head 11, and its effect is in order to prevent that screw 1 from skidding off running under the situation such as vibration.Be provided with hollow portion 22 in the middle of the said collar 2, screw thread 12 can pass hollow portion 22, and the diameter of promptly said collar 2 hollow portions 22 is greater than screw thread 12 external diameters, but hollow portion 22 diameters are less than boss 131 top diameters.Therefore, collar 2 can not break away from screw 1 again after boss 131 passes hollow portion 22.Said collar 2 inboards also are provided with shell fragment 21; Shell fragment 21 rings are located at collar 2 inboards; Said shell fragment 21 tilts to assembly direction; So that collar 2 and boss 131 be difficult for breaking away from boss 131 assembling the back, better must fasten (as shown in Figure 7) with boss 131, screw 1 was with respect to the moving direction of collar 2 when described assembly direction was meant assembling.Said collar 2 outsides also are provided with outer wall 23, its effect be can be better and fixed base 20 fixing.
Comprise for the assembly method of mooring screw 10 like Fig. 2-5: the first step, a fixed base 20 is provided, which is provided with cavity 201, offer tapped hole 2011 in the cavity 201, bulge loop 2012 is arranged at said fixed base 20 tops; Second step was arranged in collar 2 on the fixed base 20, and in particular, collar 2 is set on the bulge loop 2012, and collar 2 is limited on the fixed base 20; The 3rd step; Fixed plate 30 is installed on the fixed base 20, and push down collar 2, said fixed plate 30 is provided with vestibule 301; Be provided with protruding 3011 in the vestibule 301; Protruding 3011 are pressed in (like Fig. 4) on the bulge loop 2012 with collar 2, and this moment, fixed base 20, collar 2 and fixed plate 30 constituted assembly parties 100, and the medial axis of said cavity 201, tapped hole 2011, collar 2 and vestibule 301 is on same axis 200; The 4th step, screw 1 is inserted in the assembly parts 100 along axial direction, screw thread 12 passes vestibule 301 and collar 2 successively; Be screwed into tapped hole 2011 at last; This moment, assembly parts 100 was by screw, screw 1 when being screwed into tapped hole 2011 on the collar 2 shell fragment 21 receive boss 131 compressing and on installation direction, produce deformation, shell fragment 21 is crossed boss 131 back shell fragments 21 and is recovered deformation; This moment, shell fragment 21 fastened with boss 131, and fixed plate 30 is limited between collar 2 and the bullet pad 3.
Referring to Fig. 6, when needs separated fixed base 20 with fixed plate 30, for example machinery requirement was taken maintenance or maintenance apart; As long as screw 1 is extracted; Collar 2 breaks away from fixed bases 20 at this moment, and fixed plate 30 separates with fixed base 20, because shell fragment 21 fastens on screw 1 convex platform 131 and the collar 2; Make screw 1 can not break away from fixed plate 30, thereby prevent the loss of screw 1.
More than mooring screw of the present invention and assembly method thereof have been carried out detailed description; Those skilled in the art can be understood better must understand the present invention; But be not to limit protection scope of the present invention; The improvement mode of execution that those of ordinary skills make under the guidance of core concept of the present invention all should be within protection scope of the present invention.
