Description

Technical Field

[0001] This utility model relates to a folding structure for a trampoline frame and a trampoline, belonging to the field of sporting goods. Background Technology

[0002] Trampolines are a common form of recreational and sports equipment, mainly composed of a trampoline surface, support legs, a jumping cloth, and springs. Because trampolines are generally large and heavy, they not only take up space when not in use, but also require a lot of time and manpower to move.

[0003] While existing trampolines can be disassembled and stored, their parts are scattered after disassembly, making them inconvenient to move and prone to loss. Therefore, there is an urgent need for a trampoline that can solve the problem of existing trampolines being unable to be folded and disassembled, resulting in them taking up a lot of space and being inconvenient to move. Summary of the Invention

[0004] In view of this, the present invention provides a trampoline support folding structure and a trampoline having the folding structure, so as to solve the above-mentioned problems existing in the prior art.

[0005] One of the objectives of this utility model is to provide a folding structure for a trampoline frame, the technical solution of which is as follows:

[0006] A trampoline support folding structure includes multiple telescopic columns and a folding mechanism disposed between adjacent telescopic columns. The telescopic columns and the folding mechanism are arranged to form a regular polygon, and the telescopic columns have a locking mechanism.

[0007] The folding mechanism includes a first connector located on the upper edge of the side wall of the telescopic column, a second connector located on the lower edge of the side wall of the telescopic column, a folding rod that connects adjacent telescopic columns by rivets and can rotate axially along the connection point, and an X-shaped frame that connects adjacent telescopic columns by rivets and the first and second connectors respectively and can rotate axially along the connection point. The two rods of the X-shaped frame are connected by rivets at their intersection, and the two rods can rotate axially along the rivets.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the folding rod includes two support rods of equal length, with a slot below the opposite side of the two support rods. A third connector is provided in the slot, and rivets connected to the support rods are provided on both sides of the third connector. The support rods can rotate along the axial direction of the rivets.

[0010] Furthermore, it also includes a tow bar, one of the multiple telescopic columns extending upwards to form a sleeve, the tow bar being installed in the sleeve, and the position of the tow bar being adjusted by a hand-tightening bolt passing through the side wall of the sleeve.

[0011] Furthermore, the locking mechanism is a hand-tightened bolt.

[0012] Furthermore, the bottom of the telescopic column has an anti-slip pad.

[0013] Another objective of this utility model is to provide a trampoline, including a trampoline frame and a jumping cloth, wherein the trampoline frame has the aforementioned folding structure.

[0014] The beneficial effects of this utility model are:

[0015] This trampoline can be folded, stored, and transported without disassembly, taking up little space. The folding operation is simple, and each component is independent and does not affect the others. If there is any damage, only the corresponding part needs to be replaced. Installation and maintenance are convenient and cost-effective. Attached Figure Description

[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0023] Example 1

[0024] like Figure 1-2 As shown, the trampoline support folding structure includes multiple telescopic columns 1 and a folding mechanism disposed between adjacent telescopic columns 1. The telescopic columns 1 and the folding mechanism surround to form a regular polygon, and the telescopic columns 1 have a locking mechanism 2.

[0025] The folding mechanism includes a first connector 3 located on the upper edge of the side wall of the telescopic column 1, a second connector 4 located on the lower edge of the side wall of the telescopic column 1, a folding rod 5 that connects adjacent telescopic columns 1 by rivets to the first connector 3 and can rotate axially along the connection point, and an X-shaped frame 6 that connects adjacent telescopic columns 1 by rivets to the first connector 3 and the second connector 4 respectively and can rotate axially along the connection point. The two rods of the X-shaped frame 6 are connected by rivets at their intersection, and the two rods can rotate axially along the rivets.

[0026] In the retracted state, the telescopic column 1 is in a stretched state. When unfolded, the telescopic column 1 retracts. During the retraction process, the folding rod 5 unfolds and the horizontal angle of the X-shaped frame 6 decreases. After being fully unfolded, the telescopic column 1 is locked in its telescopic state by the locking mechanism 2, and the folding rod 5 and the X-shaped frame 6 form a support.

[0027] In another embodiment of this utility model, such as Figure 3 As shown, the folding rod 5 includes two support rods of equal length. The two support rods have a slot on the lower side of their opposite sides. A third connector 7 is provided in the slot. Rivets connected to the support rods are provided on both sides of the third connector 7. The support rods can rotate along the axial direction of the rivets.

[0028] The slots on the support rods are located below, which on the one hand provide a limit to the axial movement of the support rods, and on the other hand, the third connector 7 is embedded, with the ends of the two support rods abutting each other, thus forming a relatively stable and non-deformable support.

[0029] In another embodiment of this utility model, a tow rod 8 is also included. One of the multiple telescopic columns 1 extends upward to form a sleeve 9. The tow rod 8 is disposed in the sleeve 9, and the position of the tow rod 8 is adjusted by a hand-tightening bolt (a bolt with a hexagonal or plum blossom-shaped cap on the head, which the user can grasp the head to adjust the tightness without the aid of tools) passing through the side wall of the sleeve 9.

[0030] The tow bar 8 is designed for easy transport and can also serve as a support structure when unfolded, allowing users to maintain their balance by holding onto the tow bar 8 when jumping on the trampoline.

[0031] In another embodiment of this utility model, the locking mechanism 2 is a hand-tightening bolt, or it can be other easily adjustable fixing methods.

[0032] Taking the hand-tightening bolt as an example, the locking method is explained as follows: After the telescopic column 1 is retracted, it is in the state of being fitted with support rods of different diameters. After the hand-tightening bolt passes through each support rod in sequence, it can limit the telescopic state to achieve locking.

[0033] In another embodiment of this utility model, the bottom of the telescopic column 1 has an anti-slip pad to increase its friction and prevent displacement.

[0034] Example 2

[0035] A trampoline includes a trampoline frame and a jumping cloth. The jumping cloth is disposed on the upper end face of the trampoline frame and fixedly connected. The trampoline frame has the folding structure of the trampoline frame in Embodiment 1.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
