DETAILED DESCRIPTION
[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.
[0018] Embodiment 1: refer to Figures 1-3 A table tennis training net frame, including first supporting cylinder 2 and second supporting cylinder 15, supporting cylinder 2 and second supporting cylinder 15 are all set up connecting groove 13, two connecting grooves 13 are all set up limiting groove 14, connecting groove 13 is inserted with connecting edge 9, connecting edge 9 is fixedly connected with limiting edge 10, limiting edge 10 is located in limiting groove 14, connecting edge 9 is fixedly connected with net cloth 3, limiting edge 10 is blocked by blocking mechanism, first supporting cylinder 2 is fixedly connected with fixed seat, second supporting cylinder 15 is rotatably connected with fixed seat through bearing, second supporting cylinder 15 is fixed through fixed mechanism, limiting edge 10 and limiting groove 14 are used to limit connecting edge 9, prevent connecting edge 9 from separating from connecting groove 13, when net cloth 3 is damaged, limiting edge 10 is unblocked by blocking mechanism, so that connecting edge 10 is taken out, net cloth 3 is disassembled and replaced.
[0019] The blocking mechanism comprises a stopper 11, a rotating shaft 12 is fixedly connected to the stopper 11, the rotating shaft 12 is rotatably connected to the supporting cylinder 2 through a bearing, and the bearing is a thrust ball bearing. By rotating the stopper 11, the stopper 11 abuts against the connecting edge 9, so that the connecting edge 9 is limited.
