The present disclosure relates to the technical field of trampolines, in particular to a support structure for a trampoline safety net.
Trampolines can be used as fitness and entertainment equipment, which is deeply loved by young people and children. Some trampolines are provided with safety nets. A plurality of fence poles are vertically arranged on a trampoline main body and fixed to edges of a safety net. Most of the safety nets are made of soft, thin and light materials. The edge of the safety net between two fence poles will collapse due to being fixed and not tightened, resulting in reduced protective performance of the safety net. In addition, due to small contact area of joints between the fence poles and the safety net, the capability of bearing external tearing force is weak, and thus the safety net is prone to damage. A hard ring connection structure is arranged on the edges of an upper end of the safety net, which can effectively solve the problem of edge collapse of the safety net. However, the fence poles and the hard ring connection structure are complex, inconvenient to connect, and cumbersome to mount, use and store, bringing poor usage experience to users.

Further, a width of the openings 11 is matched with a width of the connecting pieces 3, such that the connecting pieces 3 can be clamped on inner sides of the openings 11 after being connected to the connecting strips 2 to prevent the annular structure formed by the connecting strips 2 and the connecting pieces 3 from shaking greatly during use of the trampoline; moreover, it is possible to pre-clamp the connecting pieces 3 to the openings and then connect all the connecting strips 2 to the connecting pieces 3 in sequence, which facilitates the mounting and fixation of the safety net.
A specific connection between the connecting strips 2 and the connecting pieces 3 is as follows: each of the connecting pieces 3 is of a square tube structure, first limiting spring pieces 31 bent towards an inner side of a square tube are arranged on side walls of two ends of the connecting piece 3, respectively, each of the connecting strips 2 is of a square connecting strip structure, and a section size of the connecting strip 2 is matched with a section size of the inner side of the square tube of the connecting piece 3, such that when the connecting strip 2 is inserted into the connecting piece 3, the connecting strip 2 is in clearance fit with the connecting piece 3. Side surfaces of two ends of each connecting strip 2 correspond to side surfaces of the first limiting spring pieces 31 of each connecting piece 3 and are provided with clamping grooves 21, respectively, and the clamping grooves 21 are oblique straight grooves with right triangle sections, matched with the first limiting spring pieces 31. When the connecting strip 2 is inserted into the connecting piece 3, free ends of the first limiting spring pieces 31 abut against right-angle side surfaces of the clamping grooves 21. In this case, the first limiting spring pieces 31 can prevent the connecting strip 2 from moving along a direction opposite to an insertion direction.
Further, two first limiting spring pieces 31 are arranged on two opposite side walls of two ends of each connecting piece 3, respectively, and correspondingly, two clamping grooves 21 are arranged at positions, corresponding to two first limiting spring pieces 31 on each connecting piece 3, of end portions of each connecting strip 2, respectively, which facilitates the further connection and fixation between the connecting strip 2 and the connecting piece 3.
A top end of each fence pole 1 is further provided with a cover cap 13, the cover cap 13 covering the top end of the fence pole 1 and wrapping a tube wall of the fence pole 1 therein. A composite inner cover 130 is arranged inside the cover cap 13, the composite inner cover 130 being integrated with the cover cap 13 in design and having an outer diameter smaller than an inner diameter of the fence pole and an inner diameter greater than an outer diameter of the fence pole, and when the fence pole 1 is covered by the cover cap 13, the tube wall of the fence pole 1 is wrapped between the composite inner cover 130 and the cover cap 13, which increases the fixation strength of the tube wall of the fence pole 1.
