Portable badminton net storage device capable of automatic net collection

Abstract

The main working principle of the application is to run through the feature of converting kinetic energy into elastic potential energy by the clockwork spring. We pull out the net, and at the same time, we store energy for the clockwork spring. When the clockwork spring is released, it shrinks back, which drives the net to be retracted into the container. The specific operation mode can refer to the tape measure. The problems of difficult installation of the badminton rack, slow net retraction, easy damage of the net and knotting are solved.

[0005] The following are specific embodiments of the present invention. It should be noted that the present invention is not limited to the following specific embodiments. All equivalent modifications made based on the technical solutions of this application fall within the protection scope of the present invention.

[0006] The automatic net retraction and deployment mechanism works as follows: The inner end of the 7-spring is clamped to the slot of the 6-spring fixing piece, and the outer end of the 7-spring is connected to the net. After the net is installed, it is wound up. When the net is pulled out, it drives the 7-spring to rotate, charging it. When released, the net retracts into the space between the 1-outer shell and the 4-inner shell through the rotation of the 7-spring. The 6-spring fixing piece is fixed to the 1-outer shell and therefore does not rotate. The 7-spring is locked to the net and the 4-inner shell, preventing it from being pulled out. The 7-spring's energy storage mechanism involves inward retraction as the 3-cylindrical roller bearing rotates; its specific operation can be referenced from a measuring tape.

[0007] Net installation during pull-out: 9-Net fixing piece connects to the net, with screws for fastening. After the net is pulled out to the desired position, insert 9-Net fixing piece into 8-Net installation tube, which connects to the stand, etc., and is supported on the ground.

[0008] Net positioning: After pulling the net to the required length, place the 2-net clips on the top and bottom sides of the net, and then tighten the fasteners with the 5-tightening screws. In this way, the net's retraction path is blocked by the 2-net clips. The 2-net clips and the 5-tightening screws are two separate parts, used only for fixing the position.

[0009] The outer side of the 3-cylindrical roller bearing is connected to the 1-outer shell, and the inner side of the 3-cylindrical roller bearing is connected to the 4-inner shell. In this way, the rotation of the 7-spring spring, which drives the 4-inner shell to rotate, will not affect the 1-outer shell.
