Detailed Description

The following detailed description of the utility model, taken in conjunction with the accompanying drawings, will provide those skilled in the art with a more readily understood understanding of how the utility model may be practiced. While the present utility model has been described in connection with the preferred embodiments thereof, these embodiments are set forth only and are not intended to limit the scope of the utility model.

First embodiment: referring to fig. 1-2, an environment-friendly heavy-duty deformation-resistant paperboard comprises: an upper paperboard 1, a lower paperboard 2 and a connecting strip 3; the upper paperboard 1 and the lower paperboard 2 are fixedly connected through a connecting strip 3.

In this embodiment, the upper board 1 and the lower board 2 are corrugated boards; the lower end part of the upper paperboard 1 is provided with a plurality of evenly distributed grooves 11; the grooves 11 are all formed in the same direction.

The connecting strip 3 is fixedly arranged at the upper end of the lower paperboard 2, and the fixing can be bonding, namely the lower end of the connecting strip 3 is bonded with the upper end of the lower paperboard 2; the longitudinal sections of the connecting strips 3 are all inverted trapezoids; in this embodiment, a plurality of connecting strips 3 are provided, and a plurality of connecting strips 3 are uniformly distributed at the upper end of the lower paperboard 2 and have the same laying direction; the size of the connecting strip 3 is matched with the size of the groove 11; when the upper paper board 1 and the lower paper board 2 are fixedly connected through the connecting strips 3, the connecting strips 3 and the grooves 11 are arranged in a one-to-one correspondence, the connecting strips 3 are completely embedded into the grooves 11, the lower end face of the upper paper board 1 is abutted with the lower end face of the lower paper board 2, the connection and fixation of the upper paper board 1 and the lower paper board 2 are realized in a joggle-joint-like manner, the using amount of glue is reduced, and the aim of environmental protection is achieved; meanwhile, it should be noted that the connecting strip 3 is made of plastic, and the connecting strip 3 and the groove 11 are matched, so that the upper paperboard 1 and the lower paperboard 2 can be fixedly connected, and the connecting strip 3 can be used as a supporting framework to improve the deformation resistance of the paperboard.
