Abstract

The utility model discloses a magnetic rod which can flex and deform freely and comprises a plastic rod body and magnetic blocks fixed on two ends of the rod body, wherein the middle part of the rod body is a corrugated pipe, and the corrugation of the corrugated pipe is of a taper angle shape. The structure can allow the rod body to flex and deform freely in certain size range. A plurality of the magnetic rods which can flex and deform freely are combined with a plurality of magnetic metal balls, the arrangement is performed at will, and the flexing is free so as to create various structural shapes, thus the interest of a toy is increased, and the imagination and the creativeness of children can be improved better.

Description

Retractable distortion magnetic bar

Technical field

The utility model relates to a kind of magnetic toy, especially relates to the retractable distortion magnetic bar that a kind of and magnetic metal balls can be combined into various three-dimensional shapes.

Background technology

Building or be assembled into the shape of various structures or the toy of pattern with the assembly of multiple shape, is the imagination and the creationary toy that can help to improve children.The toy of being made up of a plurality of magnetic bars and a plurality of magnetic metal balls just is suitable for this type toy, yet the magnetic bar of this toy of prior art generally all is the regular length and the magnetic bar that can not be out of shape, the magnetic bar collocation of this structure planform dumb, combination is few, inspires children's imagination and creationary effect to be limited to.

China patent ZL03826649.0 discloses a kind of magnetic toy, and it is the magnetic toy that comprises a plurality of bar magnets and a plurality of Metal Ball.Its bar magnet be by magnetic, can repeat the magnetic core that moulding metal material constitutes, the body that has flexible synthetic resin to constitute, and the magnetic end disc that is anchored on each end of this SMIS is formed.The bar magnet complex structure of this structure, the manufacturing cost height, though can flexural deformation, can not elongate.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of prior art, and a kind of magnetic bar of simple in structure, with low cost, retractable distortion is provided.

The purpose of this utility model realizes that by following scheme it comprises the magnetic patch of plastics barred body and barred body two ends internal fixation, and the middle part that it is characterized in that described barred body is a bellows, and ripple is angular shape.

In order to guarantee that barred body has certain support strength, the pipe thickness of bellows generally requires about 0.38～1.0mm.

The advantage of the utility model retractable distortion magnetic bar is: the barred body of the magnetic bar of this structure can adopt blow molding process or Shooting Technique one-shot forming, and is cheap for manufacturing cost.The middle part of barred body is a bellows, and its ripple is angular shape, and this structure can make barred body retractable, distortion in the certain size scope.This a plurality of retractable distortion magnetic bars and the combination of a plurality of magnetic metal balls, collocation is followed one's bent, and is capable of expansion and contraction, can create the shape of a variety of structures, increased the interest of toy, can improve children's imagination and creativeness better.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described further.

As shown in Figure 1, a kind of retractable distortion magnetic bar, it comprises the magnetic patch 3 at plastics barred body and barred body two ends, described barred body two ends 2 internal fixation magnetic patch 3 is arranged, the middle part of barred body is a bellows 1, and ripple is 1 angular shape, and the pipe thickness of bellows 1 is 1mm.

As Fig. 2, shown in Figure 3, the retractable of this structure distortion magnetic bar, barred body is retractable, distortion in the certain size scope.Wherein Fig. 2 is the magnetic bar of elongation, and Fig. 3 is crooked magnetic bar.

Claims

1, a kind of retractable distortion magnetic bar, it comprises the magnetic patch (3) of plastics barred body and barred body two ends (2) internal fixation, it is characterized in that: the middle part of described barred body is bellows (3), and ripple is (3) angular shape.

2, according to the described retractable distortion of claim 1 magnetic bar, it is characterized in that: the pipe thickness of bellows (3) is 0.38～1.0mm.
