Abstract

An automatic rebounding type tennis training wall is disclosed. A driving motor inside the automatic rebounding type tennis training wall is connected to a power source via a temperature controller; front and rear side surfaces of supporting fixing columns are hinged with the bottoms of front and rear rotating support shafts respectively; first fixing bolts pass through front fixing holes, front side surfaces of the supporting fixing columns, rear side surfaces of the supporting fixing columns, and rear fixing holes successively, and then are threadingly connected to first fixing nuts; and thetemperature controller includes a metal casing, a left power line, a right power line, a left conductive sheet, a right conductive sheet, a left conductive folding strip, a right conductive folding strip, a left wax strip, a right wax strip and an intermediate conductive portion. The automatic rebounding type tennis training wall has a strong fixation strength, and is easy to carry and install.

Description

technical field [0001] The invention relates to a tennis training facility, in particular to an automatic rebound tennis training wall, which is particularly suitable for providing an automatic rebound tennis training wall with strong fixing strength and easy to carry. Background technique [0002] Tennis, together with golf, bowling, and billiards, is known as the world's four major gentleman's sports. Its unique charm has long been deeply rooted in the hearts of the people. It is a sport suitable for all ages, and it is more and more loved by our people.
