Referring to fig. 1-4, the present invention provides a technical solution:

the utility model provides a vocabulary contrast explanation device, includes a pair of case 1, case 1 is cuboid and inside and is equipped with inner chamber 10, and the front end of inner chamber 10 is provided with layering 2 that is the circular arc structure for the middle vocabulary paper 5 of its below of can closely laminating of layering 2. The rear end of the inner cavity 10 is symmetrically provided with rubber bands 3. The rear end of the storage box 1 is symmetrically provided with a through hole 11, and the rear end of the rubber band 3 is inserted into the through hole 11 and is bonded. The symmetry of inner chamber 10 bottom front end corner is equipped with projection 12, and the interlude of projection 12 is equipped with boss 13, and the projection 12 outside has closely cup jointed spring 14, and spring 14's bottom round and boss 13 joint for spring 14 is firm on projection 12, is difficult to the atress slippage. The two ends of the top surface of the pressing strip 2 are provided with trepanning 21 which is sleeved with the spring 14, and the top end of the spring 14 is internally inserted with a pressing column 22, so that the spring 14 is pressed on the trepanning 21 to be connected with the pressing strip 2 into a whole, and the pressing strip 2 can press a plurality of layers of vocabulary paper 5 below the pressing strip through the elasticity of the spring 14. The front end of the rubber band 3 is bonded with a sleeve column 30, an L-shaped fixture block 31 is arranged below the front end of the sleeve column 30, and the fixture block 31 is in clamping fit with the pressing strip 2, so that the two side edges of the vocabulary paper 5 can be pressed by the rubber band 3.

In the embodiment, the storage box 1 and the pressing bar 2 are made of PP materials and are integrally formed, and the storage box is light in weight, good in toughness and rigid in strength, so that the storage box is durable.

Further, a rubber pad 20 is bonded to the bottom surface of the bead 2, which can increase friction force, so that the bead 2 is tightly attached to the vocabulary paper 5.

Specifically, the length of the rubber band 3 is half of that of the storage box 1, so that the side edge of the vocabulary paper 5 can be pressed by the rubber band 3 after the rubber band 3 is doubled due to self deformation, the elasticity of the rubber band 3 is ensured, and the rubber band 3 is enabled to keep longer service life.

In addition, a fan-shaped groove 15 is formed in the edge of the side face of one long side of the storage box 1, a groove 16 is formed below the fan-shaped groove 15, a hinge 4 is fixedly connected into the groove 16 through a screw, and the fan-shaped groove 15 is used for placing a rotating shaft of the hinge 4, so that interference when the two storage boxes 1 are folded is avoided.

It needs to be supplemented that a plurality of vocabulary paper 5 are placed in the inner cavity 10, and the press strip 2 and the rubber band 3 are both positioned on the top surface of the topmost vocabulary paper 5, so that the vocabulary paper 5 is stably placed in the inner cavity 10 and is not easy to be confused when being carried.
