Abstract
The utility model relates to a double-edge double-point restriction fixing device. The restriction fixing device comprises a base and a restriction fixing component. The base is of a cuboid structure. An abnormal shaped hole is formed in the middle of the base. The abnormal hole is composed of two cylindrical through holes and a reversed T-shaped through hole. The restriction fixing component is composed of a fixing seat, two elliptical rings, two nut cups, two stop pins and two springs. Plane gaps are formed in the middle of the two stop pins, and two ends of each plane gap are arcs. The lower portion of the fixing seat is of a reversed T-shaped structure. Two sides of the upper portion of the fixing seat are both of a double-T-shaped structure, a semi-elliptic through hole is formed in the middle of the fixing seat, a square through hole is formed in the middle of the double-T-shaped structure, and a groove which is used for placing the stop pins is formed at the bottom of the square through hole. The double-edge double-point restriction fixing device has the advantages of being simple in structure, light in weight, strong in bearing capacity and convenient to install, capable of achieving double-point restriction in two directions one time and meeting the quick-disassembling requirements of a plane.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail:
Below in conjunction with accompanying drawing the utility model is described in further detail, sees also Fig. 1 to Fig. 9.
A kind of bilateral two point constraint anchor fitting comprises base 1, constraint fixation kit 2, as shown in Figure 1; Described base 1 is rectangular structure, and the centre has profiled holes 8, and as shown in Figure 2, profiled holes 8 is made up of two column type through holes 9 and the font of falling a T through hole 10, as shown in Figure 3, at base 1 four jiaos four step through-holes 11 is arranged; Described constraint fixation kit 2 is made up of permanent seat 3, two elliptical rings 4, two 5, two stop pins 6 of block and two springs 7; Have plane breach 20 in the middle of described two stop pins 6, two ends are circular arc, as shown in Figure 9; Described permanent seat 3 belows are the font structure of falling T 12, as shown in Figure 5, both sides, permanent seat 3 top are double T font structure 14, middle for having half elliptic hole 13, in the middle of double T font structure 14, have a square through hole 15, square hole 15 bottoms have for the groove 16 of placing stop pin 6, as shown in Figure 4; Described two blocks 5 are processed by the cylinder chamfered edge, having square open aperture 17 perpendicular to the chamfered edge face, be parallel on the chamfered edge face and have manhole 18 near block 5 bottoms, as shown in Figure 7, after spring 7 is installed on square open aperture 17, block 5 is packed on the double T font structure 14 of permanent seat 3, and two stop pins 6 insert the manhole 18 from both sides respectively; Described two elliptical rings 4 are inserted in the half elliptic hole 13.
