Linear bearing telescopic rod of basketball stand

Abstract

The invention provides a linear bearing telescopic rod of a basketball stand, and belongs to the field of sports goods. The telescopic rod comprises a locking guide rod movably sleeved with a locking jacket component in a matched manner; a reserved shaft shoulder and a reserved threaded hole are formed in the end face of the locking guide rod, the locking guide rod and a nylon guide sleeve are concentrically matched through the shaft shoulder and the threaded hole, and after matched installation, the locking guide rod and the nylon guide sleeve are assembled through a threaded through a hexagon socket cap screw, the lower end face of the locking guide rod is provided with an external thread to be connected with the lower end of the locking jacket component through a thread, the lower end face of the locking jacket component is provided with the external thread matched with an external thread sleeve to lock the telescopic rod. A linear bearing in the locking jacket component is tightly matched with the locking guide rod, and a bearing ball in the linear bearing is in point contact with the locking guide rod, so that the use load is small. The locking guide rod adopts a plain shaft, when the basketball stand ascends and descends, stretching and retracting are smooth, the nylon guide sleeve is used at the end, effective guiding and righting can be achieved, the coaxial state is always kept during reciprocating displacement motion, friction sound is low, and the whole telescopic rod is stable and durable in linear motion.

Description

technical field [0001] The invention relates to the technical field of sporting goods, and more specifically relates to a linear bearing telescopic rod of a basketball stand. Background technique [0002] The basketball stand is an indispensable sports equipment for the basketball stand, but the ordinary telescopic rod has a cumbersome appearance. When lifting and lowering, the large tube is covered with the small tube. The mechanical friction between the inner wall of the large tube and the outer wall of the small tube is serious, there will be abnormal noise, and the lifting is different. The heart, the movement is not smooth, and the lock is not smooth. The invention provides a linear bearing telescopic rod of a basketball stand that can overcome the above problems. It has a light appearance, and the load-bearing ball in the linear bearing is in point contact with the guide rod, so the operating load is small. The steel ball rotates by friction to obtain high precision ...
