[0036] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementations:

[0037] See also Figure 1-Figure 12 A foldable trampoline includes a trampoline guard net body, which includes a plurality of guard net units 1 connected in sequence. Two adjacent guard net units 1 can be connected in a rotating manner to facilitate the change of the shape of the trampoline guard net body.

[0038] In this embodiment, at least one rotating connection is detachable so that the corresponding two net protection units 1 can be separated from each other. The rotating connection specifically refers to the position where two adjacent net protection units 1 rotate.

[0039] Regarding the matching structure between two adjacent net protection units 1, in this embodiment, the left and right ends of the net protection unit 1 are respectively configured with a first connection unit 2 and a second connection unit 3. For example, the left end of the net protection unit 1 is installed with the first connection unit 2, and the right end is installed with the second connection unit 3, then the first connection unit 2 at the left end of one net protection unit can match with the second connection unit 3 at the right end of another adjacent net protection unit.

[0040] Furthermore, a connecting member 4 is disposed between the first connecting unit 2 and the second connecting unit 3 that cooperate with each other, such as Figure 3 , Figure 5 As shown, the first connecting unit 2 and the second connecting unit 3 are rotatably connected to the connecting member 4 respectively, so as to realize the rotational connection cooperation relationship between two adjacent net protection units.

[0041] In this embodiment, Figure 7 As shown, the first connection unit 2 includes a U-shaped first connection head 21, an installation cavity is formed between the upper and lower parts of the first connection head 21, and two corresponding through holes are respectively opened on the upper and lower parts thereof.

[0042] like Fig. 9 As shown, the second connection unit 3 includes a U-shaped second connector 31, a mounting cavity is formed between the upper and lower parts of the second connector 31, and two corresponding through holes are respectively opened on the upper and lower parts. The outer diameter of the second connector 31 is smaller than the inner diameter of the first connector 21, so that at least part of it can penetrate and be arranged in the mounting cavity of the first connector 21.

[0043] like Figure 8 As shown, at least three through holes are longitudinally opened on the connecting member 4, two of which are used to penetrate the connecting shaft 5, and the other is used to penetrate the plug 6. Matching therewith, one of the through holes on the first connecting head 21 and one of the through holes on the second connecting head 31 are also used to penetrate the connecting shaft 5. Figure 5 As shown, the two ends of the connecting member 4 are respectively arranged in the installation cavity of the first connecting head 21 and the installation cavity of the second connecting head 31, and then the holes for passing the connecting shaft 5 are aligned accordingly. After the connecting shaft 5 is assembled, the first connecting unit 2 and the connecting member 4 can form a rotational matching relationship, and the second connecting unit 3 and the connecting member 4 can form a rotational matching relationship. As one of the options, the connecting shaft 5 can be connected with a screw, and the lower end of the screw is locked by a nut to form a longitudinal positioning.

[0044] At the same time, the hole (first hole 91) on the connecting member 4 for inserting the plug 6, the hole (second hole 92) on the first connecting unit 2 for inserting the plug 6, and the hole (second hole 92) on the second connecting unit 3 for inserting the plug 6 are also aligned with each other, and then the plug 6 is passed through. When the plug 6 is inserted, the protective net unit 1 is positioned so that it cannot rotate.

[0045] In order to improve the stability of the structure, in this embodiment, Figure 8 As shown, the longitudinal hole opened on the connecting member 4 is equipped with a sleeve 41 whose outer end extends outside the connecting member to fill the gap between the connecting member 4 and the first connecting unit 2 and / or the second connecting unit 3. The filling state is as shown in FIG. Figure 5 shown.

[0046] When the state of the trampoline needs to be changed, the corresponding latch 6 is pulled out.

[0047] In this embodiment, the trampoline guard net body has a first state of being unfolded as a trampoline guard net, a second state of being half-expanded as a screen, and a third state of being folded, wherein the half-expanded state is between the unfolded state and the folded state.

[0048] like Figure 1 As shown, the first state of the trampoline guard net body is formed in a circle, and adjacent guard net units 1 are connected in sequence. An elastic mesh is arranged in the space surrounded by the elastic mesh, and the elastic mesh is connected to the guard net unit by elastic connectors. For the elastic mesh and the elastic connector, reference can be made to the existing trampoline design.

[0049] Specifically, the lower end of the protective net unit 1 includes a cross bar 11 for connecting an elastic connecting member, such as Figure 2 , Figure 4 As shown, as one of the options, one end of the elastic connector can be in the form of a hook to be directly hooked on the crossbar 11. The two ends of the crossbar 11 are respectively assembled on the first connecting unit 2 and the second connecting unit 3. Figure 4 shown.

[0050] Furthermore, the bottom of the protective net unit 1 includes a supporting foot 12, which determines its overall height according to the set height of the elastic mesh cloth and is mainly used to raise the height of the protective net to improve adaptability.

[0051] There is also a vertical rod 13 above the cross rod 11, and the vertical rod 13 can be assembled on the first connecting unit 2 and / or the second connecting unit 3. For example, a hollow pipe 14 for installing the vertical rod 13 is arranged on the first connecting unit 2 and / or the second connecting unit 3, and then locked by fasteners.

[0052] A protective net unit 1 can be equipped with two upright poles 13, and the first protective net 81 is mounted on the upright poles 13. Figure 1 , Figure 2As shown, the design of the upper end of the vertical pole can be specifically selected according to actual needs. For example, if the overall height of the protective net unit 1 is relatively high, a locking member 7 can be added to the upper ends of the two adjacent protective net units. The locking member 7 includes a notch that is compatible with the shape and size of the upper end of the vertical pole. The upper ends of the two adjacent protective net units are locked by buckling the notch onto the vertical pole.

[0053] After adjacent guard net units are connected, there will be a certain gap between them. To ensure the safety of the guard net, in this embodiment, a second guard net 82 is arranged between adjacent guard net units. At least one second guard net 82 is detachable from the corresponding guard net unit so that the shape change of the trampoline guard net body will not be affected after the second guard net 82 is set.

[0054] If the overall aesthetics of the trampoline guard net body in the first state is to be improved, an outer cover may be installed on the trampoline guard net body at the positions of the crossbar, the first connecting unit, the second connecting unit, and the connecting piece, and the outer cover may cover the above-mentioned parts. Figure 1 As shown, when the shape needs to be changed, the outer cover can be removed.

[0055] like Fig.11 As shown, the second state of the trampoline guard net body is shown. In this state, it can be used as a screen. During specific operation, the pins are taken out to allow the guard net unit 1 to rotate. After being placed in the screen state, the corresponding pins 6 are inserted between two adjacent guard net units to lock the positions of the guard net units, and the redundant pins can be stored on the first connecting unit 2 and / or the second connecting unit 3 at the outer ends of the two outermost guard net units.

[0056] like Fig.12 As shown, the third state of the trampoline guard net body is a fully folded state, which can be used for folding and storage. The overall space occupancy rate of this state is the lowest. After folding, the latch 6 can be inserted into the corresponding position to prevent the loss of the latch.

[0057] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
