[0021] The present invention will be further described in detail below with reference to the accompanying drawings.
[0022] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.
[0023] Examples, such as Figure 1-4 As shown, a trampoline support structure includes an upright main support section and an inclined secondary support section that is detachably connected to the main support section. The main support section and the inclined secondary support section are Y-shaped. The main support section serves as a fulcrum, and the inclined secondary support section is located near the middle of the main support section. The upper V-shaped portion of the overall structure of the main support section and the inclined secondary support section is used for support and connection with the upper main body of the trampoline, while the lower portion of the main support section provides support to the ground, etc. The bottom of the main support section is the fulcrum of the entire support structure. It is preferable to use steel for both the main support section and the inclined secondary support section, as this offers a suitable balance of cost and strength. Importantly, the main support section and the inclined secondary support section are detachably installed and fixed, facilitating transportation, disassembly, and adjustment.
[0024] Specifically, the main support portion and the secondary inclined support portion are detachably connected by a main-secondary connector. The main-secondary connector includes a main connecting sleeve 11 that is sleeved and fixed to the main support portion and extends vertically, and a secondary inclined connecting rod 12 that is fixedly connected to the outer wall of the main connecting sleeve 11 and inclined relative to the main connecting sleeve 11. Both the main connecting sleeve 11 and the secondary inclined connecting rod 12 can be made of steel. The main connecting sleeve 11 is preferably cylindrical, and the secondary inclined connecting rod 12 can be a rectangular rod, a circular rod, or some approximately rectangular long rod, with rounded ends. Existing rod structures are generally feasible. The included angle between the main connecting sleeve 11 and the secondary inclined connecting rod 12 is generally controlled between 20 and 70 degrees. The secondary inclined connecting rod 12 is inclined diagonally upwards to the left on the left side of the main connecting sleeve 11 or diagonally upwards to the right on the right side.
[0025] Preferably, the main support portion includes a vertically extending main support rod 21 and a vertically extending main support sleeve 22 sleeved on the upper part of the main support rod 21 and adjustable and fixed vertically. The top of the main support sleeve 22 is fixed with a horizontally extending main mounting support sleeve 221. The vertical adjustment of the main support sleeve 22 on the main support rod 21 is for better installation and positioning, ensuring positional accuracy. Because there may be dimensional deviations, there is an adjustment structure to make it more level and accurate. The main mounting support sleeve 221 is horizontal and is used to connect and support the structure above the trampoline.
[0026] Preferably, the main connecting sleeve 11 is sleeved and fixed on the outside of the main support rod 21. Both the main connecting sleeve 11 and the main support rod 21 have first mounting holes 10 that pass through from front to back and correspond to each other, and are fixed by first front and rear bolts 101. The main connecting sleeve 11 is located below the main support sleeve 22. Only one first mounting hole 10 is needed on both the main connecting sleeve 11 and the main support rod 21, mainly to determine the position of the main and auxiliary connecting parts. Of course, multiple first mounting holes 10 can also be set on the main support rod 21, which is also conducive to the adjustment of the main connecting sleeve 11. The first front and rear bolts 101, which are fixed in position, pass through the first mounting and fixing holes 10 on the main connecting sleeve 11 and the main support rod 21, respectively, to lock them in place. The first mounting and fixing holes 10 can be threaded holes. If they are through holes, the first front and rear bolts 101 also need to be equipped with a nut at the end of the stud. That is, after the stud of the first front and rear bolts 101 passes through the first mounting and fixing holes 10 on the main connecting sleeve 11 and the main support rod 21, the nut is screwed into the other end. In other words, the main connecting sleeve 11 and the main support rod 21 are clamped between the head of the first front and rear bolts 101 and the nut to achieve fixation.
[0027] Preferably, the outer side wall of the main support sleeve 22 is fixed with an adjusting fastening nut 222 that communicates with the interior of the main support sleeve 22. The adjusting fastening nut 222 is equipped with an adjusting fastening bolt 223 that can pass through the adjusting fastening nut 222 and enter the main support sleeve 22 to abut against the outer side wall of the main support rod 21. Multiple sets of adjusting fastening nuts 222 and adjusting fastening bolts 223 can be arranged vertically for better fastening effect. The adjusting fastening nut 222 itself has an inner hole through which the stud of the adjusting fastening bolt 223 passes. The outer side wall of the main support sleeve 22 needs to have a hole structure that communicates with the inner hole of the adjusting fastening nut 222 and is open inside and out. In this way, the stud of the adjusting fastening bolt 223 can enter the interior of the main support sleeve 22. The upper part of the main support rod 21 is inside the main support sleeve 22. At the beginning, the adjusting fastening bolt 223 is loosened and not screwed into the main support sleeve 22. During installation, after the main support sleeve 22 is placed on the main support rod 21 and adjusted to the correct position, the adjusting fastening bolt 223 passes through the adjusting fastening nut 222 and is screwed into the main support sleeve 22, finally pressing against the outside of the main support rod 21 to fix the main support sleeve 22 on the main support rod 21.
[0028] Preferably, the secondary inclined support portion includes a secondary inclined support rod 31 inclined to the main support rod 21 and a secondary mounting support sleeve 331 fixed to the top of the secondary inclined support rod 31 and extending to the left and right. The secondary mounting support sleeve 331 is horizontal and is used to connect with the structure above the trampoline and provide support. The secondary inclined support rod 31 can be a conventional steel rod structure. In this embodiment, the fixing method can be achieved by welding, integral molding, bolt locking, or other existing fixing methods.
[0029] Preferably, the upper part of the secondary inclined connecting rod 12 and the lower part of the secondary inclined support rod 31 are provided with second mounting holes 20 that are through and correspond to each other, and are fixed by second front and rear bolts 202. The second mounting holes 20 can be threaded holes. The second front and rear bolts 202 can be screwed through the corresponding second mounting holes 20 of the secondary inclined connecting rod 12 and the secondary inclined support rod 31. Of course, as mentioned above, a nut can be provided for the stud of the second front and rear bolts 202 for better locking effect.
[0030] Furthermore, the main mounting support sleeve 221 is equipped with a left-right extending first mounting tube 41 for installation and support on both its front and rear sides. A left-right extending first connecting bolt 42 passes through the main mounting support sleeve 221 and the two first mounting tubes 41. A first locking nut 43 is fitted on the threaded part of the first connecting bolt 42. The main mounting support sleeve 221 and the two first mounting tubes 41 are positioned between the threaded head of the first connecting bolt 42 and the first locking nut 43. The first mounting tube 41 is used for direct support connection to the upper structure of the trampoline and can be pre-fixed to the lower side of the upper structure by welding or other methods. During installation, the main mounting support sleeve 221 is placed between the two first mounting tubes 41, and then the threaded part of the first connecting bolt 42 passes through all three, with the first locking nut 43 screwed into the end of the threaded part for locking and fixing. Alternatively, a connecting buckle structure or other means can be installed on the outer wall of the first mounting tube 41 for detachable fixing to the upper structure of the trampoline.
[0031] Furthermore, the secondary mounting support sleeve 331 is equipped with a second mounting tube 51 extending laterally for installation and support on both its front and rear sides. A second connecting bolt 52 extending laterally through the secondary mounting support sleeve 331 and the two second mounting tubes 51 is inserted into each of them. A second locking nut 53 is fitted on the threaded part of the second connecting bolt 52. The secondary mounting support sleeve 331 and the two second mounting tubes 51 are positioned between the threaded head of the second connecting bolt 52 and the second locking nut 53. Similar to the structural principle of the main support section, the second mounting tube 51 is also used for direct support connection to the upper structure of the trampoline. It can be pre-fixed to the lower side of the upper structure of the trampoline by welding or other methods. The installation method and other structural configurations can be referenced from the main support side.
[0032] The first assembly pipe 41 and the second assembly pipe 51 can be conventional cylindrical pipe structures, or they can be pipe structures with rectangular or polygonal outer edges.
[0033] Preferably, the lower end of the main support rod 21 is fitted with an L-shaped bottom support adapter 6. The bottom support adapter 6 can be made of plastic and serve as a bottom support foot, which is quiet and non-slip. Of course, the upright part of the bottom support adapter 6 is for the lower end of the main support rod 21 to be inserted and fitted, so the upright part needs to have an insertion hole on the upper side for the lower end of the main support rod 21 to be inserted.
[0034] The aforementioned installation method is more convenient to adjust, and the height of the main and auxiliary sides can be better adjusted to be consistent. This way, the gaps between structural components do not need to be large, the tightness will be better, and the stability will be better.
[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
