The specific embodiment
Following reference figure describes the embodiment of the utility model.
Fig. 1 is the right side view of the practical set of the utility model, and Fig. 2 is the front view of the practical set of the utility model, is main with Fig. 1,2; In conjunction with Fig. 3-Figure 11, shown in figure, the bedding plate 4 of the utility model and the connecting elements of brace summer 10; Comprise the stud 2 that passes bedding plate 4 screws; The upper and lower part of stud 2 is rotary with top nut 81 and lower nut 82 respectively, is provided with bolt connection fastener 7 between lower nut 82 and the brace summer 10, between the top nut 81 and bedding plate 4 of stud; Be set with a sleeve 3; The outer wall vertical direction of sleeve 3 is provided with a vertical slot opening 11, and the external wall cross-section direction of sleeve 3 is provided with a translot opening 12, and translot opening 12 is communicated with the bottom of vertical slot opening 11; The top of stud 2 is provided with a carved mouth groove 1, is positioned at the position of bedding plate more than 4 on the stud 2, is provided with a lateral aperture 13, one bayonet locks 9 and goes in this lateral aperture 13 through aforesaid vertical slot opening 11 or translot opening 12 pins; The bottom of lateral aperture 13 is provided with the wedge-shaped card reed 5 with stud 2 one, and the bottom of jump ring sheet 5 is equipped with spring 6.
Wherein, the stiffness factor k=F/ (L-d) of spring, wherein the F value be total force G 2-10 doubly, G=mg, m be stud, lower nut and bolt connection fastener quality and, g=9.8N/kg; The span of L is 1-2 a times of sleeve height; D is the distance of sleeve translot and sleeve lower end.F gets 5 times of total force G in the present embodiment, and L gets 1.5 times of sleeve height.
Wherein, the length of translot opening 12 is the circular arc of sleeve wall excircle 1/4.Sleeve 3 is fixed by welding on the bedding plate 4.
Describe the installation and the method for using of the utility model below in detail.
At first, according to the screw on the bedding plate 4 size, selects suitable stud 2, and according to Fig. 6,7,8 structure row processing, process carved mouth groove 1 on the top of stud 2, the middle part processes a lateral aperture 13, and jump ring sheet 5.The jump ring sheet 5 preferred wedge shapes made from stud 2 one that adopt.
According to Fig. 3,4,5 the structure that is designed processing sleeve 3, obtain having the sleeve 3 of vertical slot opening 11 and translot opening 12, translot opening 12 is communicated with the bottom of vertical slot opening 11.
According to the stud of selecting 2, the quality that lower nut 82 is added bolt connection fastener 7; Obtain its total force G; Spring 6 is designed and processes, and the stiffness factor k of spring 6 will satisfy k=F/ (L-d), and the F value is 2-10 a times of total force G; The span of L is 1-2 a times of sleeve height, and d is the distance of sleeve translot and sleeve lower end.F gets 5 times of total force G in the present embodiment, and L gets 1.5 times of sleeve height.
As shown in Figure 1, sleeve 3 is weldingly fixed on the bedding plate 4, then spring 6 is put into sleeve; Stud 2 is inserted in spring 6 spring coils, and through jump ring sheet 5 compression springs 6, the screw that sees through on the bedding plate 4 is deep into bedding plate 4 belows; And then pass bolt connection fastener 7; Adjustment stud 2 makes when lateral aperture 13 to be pressed down when the translot opening 12 of sleeve 3 is highly located, just the start position of the fluting of the translot opening 12 of alignment sleeve 3; Through lower nut 82 bolt connection fastener 7 is tightened, made the bending part 72 of bolt connection fastener 7 prop up bedding plate 4 soffits, like this can be so that bolt connection fastener 7 does not rotate with moving of bedding plate 4.During connecting bolt connection fastener 7, need make its installation as shown in Figure 1, guarantee that it can not have influence on the installation of bedding plate 4, promptly the long limit 71 of the rectangular slab of connecting bolt connection fastener 7 is perpendicular to the lateral aperture on the stud 2 13.
After finishing using, in the time of must removing bedding plate 4, at first lay down upper nut 81; Screwdriver is placed in the carved mouth groove 1 of stud 2,, made bolt connection fastener 7 break away from brace summers 10 and move downward to pressing down; When just arriving sleeve translot opening 11 Deng bayonet lock 9,90 ° of swivel bolts pull out bayonet lock 9 to sleeve translot opening 11 start positions; Because the screen resilience effect of spring 6 makes bolt connection fastener 7 be threaded to position as shown in Figure 1, and is adjacent to and can not rotates with the bedding plate once more; At this moment just can bedding plate 4 be sling, accomplish and remove.
The utility model carries out the single face operation in the time of can realizing bedding plate 4 and brace summer 10 installations; Compression, rebound effect through spring 6 make the stud 2 that has bayonet lock 9 rotate for 3 li at sleeve; And then make 7 rotations of bolt connection fastener in place, and block stud 2 through the vertical slot opening 11 on the sleeve 3, stoped the generation of working day and night; Finally reach connection between bedding plate 4 and the brace summer 10, have effects such as firm, safe, easy to operate.
As stated, the embodiment of the utility model has been carried out explanation at length, but as long as break away from the utility model point and the effect of the utility model in fact a lot of distortion can not arranged, this will be readily apparent to persons skilled in the art.Therefore, such variation also all is included within the protection domain of the utility model.
