In order to achieve the above object, the technical solution of the present invention is: a new type of anti-shock device for plug-in boards, which is characterized in that: it mainly consists of a balance plate, a supporting spring, a base, hinge copper sheets, hinge copper sheets 2. Composed of rotating shaft, conductive ball, conductive sheet, screw and elastic rubber belt. There are two rectangular small holes on the balance plate without a hole wall in the width direction, the length and width of the small holes are slightly larger than the length and width of the metal sheet of the existing power plug, and the depth of the small holes is consistent with the height of the metal sheet of the existing power plug; There are four gaps on the base, and there are two rectangular grooves, the groove positions correspond to the two rectangular small holes on the balance plate up and down and the size is slightly larger than the small holes, and each groove bottom surface is provided with two The two sides of the chute in the width direction are provided with conductive sheets; the ends of the hinge copper sheet one and the hinge copper sheet two are fixed on the rotating shaft, and can be rotated 180 degrees with the rotating shaft as the axis. The other ends of page copper sheet 1 and hinge copper sheet 2 are respectively connected and fixed with conductive balls; there are four conductive balls, two of which are placed in the chute respectively in a group, and the two in the same chute The conductive balls are connected with elastic rubber bands.

Further, the chute is in a "convex" shape, the distance from the conductive sheet is exactly equal to the diameter of the conductive ball, the minimum opening width is smaller than the diameter of the conductive ball, and the maximum opening width is larger than the conductive ball.

Further, screw holes and screws are provided on the conductive sheet for connecting with power lines.

Further, the four notches on the base correspond to the positions of the conductive sheets on the side of the groove one by one.

Compared with the prior art, the utility model has the following positive effects: 1. simple structure, convenient manufacture, low cost, and easy popularization; 2. excellent anti-shock performance, which can prolong the life cycle , greatly increasing economic benefits; 3. During use, children's curiosity can be fully respected, and safety accidents can be prevented without restricting their behavior.

detailed description

Please refer to Figure 1, a new type of anti-shock device for plug-in boards, which is characterized in that: it mainly consists of a balance board 1, a support spring 7, a base 8, a hinge copper piece 4, and a hinge copper piece 2 12 , rotating shaft 11, conductive ball 6, conductive sheet 3, screw 10 and elastic rubber band 5 are formed. The balance board 1 is located above the base 8 and is connected and fixed by the support spring 7 to the base 8; there are two rectangular holes 2 with no holes in the width direction on the balance board 1, the length and width of which are slightly larger than the metal sheet of the existing power plug respectively. Its length and width are consistent with the height of the metal sheet of the existing power plug; there are four gaps on the base 8, and two rectangular grooves 13 are provided. The rectangular holes 2 correspond up and down and the size is slightly larger than the two rectangular holes 2. The bottom surface of each groove 13 is provided with two slide grooves 9, and the two sides in the width direction are provided with conductive sheets 3; the hinge copper sheets One end of one 4 and hinge copper sheet two 12 are all fixed on the rotating shaft 11, and can rotate 180 degrees with the rotating shaft 11 as the axis, and the other ends of hinge copper sheet one 4 and hinge two 12 are connected with the rotating shaft 11 respectively. The conductive balls 6 are connected and fixed; there are four conductive balls 6, two of which are placed in the chute 9 in groups, and elastic rubber bands 5 are used between a group of conductive balls 6 in the same chute 9. connected, the conductive ball 6 can make a linear reciprocating motion along the chute 9 under the contraction and stretching of the elastic rubber belt 5; when the power plug is inserted into the small hole 2 on the balance board 1, the balance board 1 remains horizontal, and The compressed supporting spring 7 moves downward together with the power plug, and the small hole 2 enters the groove 13 in the base 8, and the copper hinge 1 4 and the copper hinge 2 12 are surrounded by the metal sheet pressure of the power plug. The rotating shaft 11 is opened, driving the conductive ball 6 to move in the direction of the conductive sheet 3 in the chute 9 and contacting the conductive sheet 3 to realize electrification. At this time, the elastic rubber belt 5 is in a state of being forcibly stretched; when the power plug is pulled out, the external force disappear, the elastic rubber band 5 shrinks to restore the original state, and drives the conductive ball 6 to move in the opposite direction to the conductive sheet 3 and separate from the conductive sheet 3, thereby realizing power-off.

Said a kind of novel anti-shock device that is used for plug-in board is owing to have used support spring 7 and balance board 1, and when children's fingers and other iron nails and the like are inserted into small hole 2, balance board 1 can be tilted, can not Keep the horizontal state, and the small hole 2 can not enter the groove 13, so it cannot be energized; meanwhile, except that the conductive ball 6, the conductive sheet 3, the hinge copper sheet one 4, and the hinge copper sheet two 12 use metal, all the other parts are all made of metal. Insulation material ensures the safety of the use process.

In summary, the utility model is simple in structure, easy to use, safe and reliable.
