Description

Technical Field

[0001] The utility model belongs to the technical field of basketball stands, and in particular relates to a movable basketball stand. Background Art

[0002] Basketball is a popular sport, and basketball stands can be seen everywhere in life. They are often set up in gymnasiums, parks, and communities, either indoors or outdoors. Basketball stands include support columns and a backboard fixed thereon, a basketball hoop fixed on the basketball board, and a base fixed thereunder. The base is divided into fixed and mobile types. The mobile base is further divided into mobile wheels fixed at the lower end of the base and mobile wheels recyclable inside the base.

[0003] The moving wheels fixed at the lower end of the base have poor stability and are inconvenient to move, and have gradually been replaced by moving wheels that can be retracted inside the base. Most of the moving wheels that can be retracted inside the base achieve movement, steering, retraction and extension of the moving wheels through the driving mechanism and lifting mechanism inside the base, and have the advantages of good stability and easy movement.

[0004] Among them, publication number CN102989147A discloses a movable basketball stand, including a basketball stand body and a base, wherein the base is a box body with an opening at the bottom and a hollow interior, two cross beams and two longitudinal beams are fixed in the base, and four bottom wheels and a bottom wheel lifting mechanism are symmetrically installed in the base 1. In its technical solution, the basketball stand is moved by the bottom wheels, and the bottom wheels can be raised and lowered, which is achieved by the bottom wheel motor driving the lead screw to rotate and feed through the chain transmission pair. The lead screw rotates left and right to play a role in pushing the crescent plate, and the four connecting rods also work at the same time, driving the rotating frame and the lifting rod, and the four wheels are raised and lowered at the same time, and the entire base is also lifted or lowered as a whole. However, the bottom of the base is designed to be open. When it is used in outdoor venues, in rainy and snowy weather or when the surface of the venue is wet, moisture in the air can easily enter the base through the opening at the bottom of the base, which will cause corrosion to the lifting mechanism and other components inside the base for a long time, seriously affecting the service life of the base.
