Description

Technical Field

[0001] The utility model relates to the technical field of sports equipment, in particular to a novel trampoline structure. Background Art

[0002] Trampoline is a sport that uses an elastic surface for jumping. It is a type of gymnastics and is known as "aerial ballet." Trampoline requires athletes to have good physical coordination, dexterity, flexibility, reaction time, a sense of air suspension, and a sense of balance. Trampoline can be used not only as a competitive sport, but also as a recreational activity. Competitive trampoline includes two events: single jump and net, while recreational trampoline is commonly found in various playgrounds for people to use for entertainment and fitness.

[0003] Most existing trampoline structures use upper and lower horizontal bars between columns to form a frame structure. When encountering a large trampoline surface, cross supports are required inside to enhance its stability. Such trampoline structures have high material costs and are time-consuming and labor-intensive to manufacture. Therefore, a new trampoline structure is needed to solve the above problems. Summary of the Invention

[0004] The purpose of the embodiments of the present utility model is to provide a new trampoline structure, aiming to solve the problems mentioned in the background technology, and the structure is simple and reliable, which is conducive to the standardized production of products and low cost.

[0005] The embodiment of the present utility model is implemented as follows: a new trampoline structure includes: a supporting mechanism and a connecting member, the connecting member is welded to the upper end of the supporting mechanism, four supporting mechanisms and connecting members are provided, and the connecting member is provided with a threaded hole; a cross bar, which is provided in conjunction with the connecting member, the cross bar is provided with a connecting hole, and there are multiple connecting holes, and the connecting holes provided in the cross bar are provided with fixing bolts, which can pass through the connecting hole and be screwed into the threaded hole to fix the cross bar and the connecting member; an M-shaped steel bar, which is welded to the inner side of the cross bar and is used to connect to the trampoline bed surface.

[0006] Preferably, the support mechanism includes: a column, which is welded to the connecting piece, a base plate welded to the bottom of the column, an inclined support welded to the middle of the column, and both the inclined support and the base plate are provided with mounting holes; an expansion bolt, which is arranged in conjunction with the mounting hole, and the expansion bolt is used to pass through the mounting hole to fix the base plate and the inclined support.

[0007] Preferably, the crossbar is a rectangular piece and the column is a square tube.

[0008] The novel trampoline structure provided by the utility model utilizes expansion bolts to fix the uprights, thereby reducing the bottom cross bars and the internal cross supports, making installation more convenient, greatly reducing the material cost, processing cost and construction cost, and having strong practicality.

[0011] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and do not limit the present invention.

[0012] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0013] See also Figure 1 The embodiment of the present invention provides a novel trampoline structure, which includes:

[0014] A support mechanism 1 and a connecting member 2, wherein the connecting member 2 is welded to the upper end of the support mechanism 1, and four support mechanisms 1 and connecting members 2 are provided. The connecting member 2 is provided with a threaded hole; a cross bar 3 is provided in conjunction with the connecting member 2, and the cross bar 3 is provided with a connecting hole, and there are multiple connecting holes. The connecting holes provided in the cross bar 3 are provided with fixing bolts 4, which can pass through the connecting hole and be screwed into the threaded hole to fix the cross bar 3 and the connecting member 2; an M-shaped steel bar 5 is welded to the inner side of the cross bar 3 and is used to connect to the trampoline surface.

[0015] like Figure 1 As shown, as a preferred embodiment of the present invention, the support mechanism 1 includes: a column 11, which is welded to the connecting piece 2, a base plate 12 is welded to the bottom of the column 11, an inclined support 13 is welded to the middle of the column 11, and both the inclined support 13 and the base plate 12 are provided with mounting holes; an expansion bolt 14, which is arranged in conjunction with the mounting hole, and the expansion bolt 14 is used to pass through the mounting hole to fix the base plate 12 and the inclined support 13.

[0016] like Figure 1 As shown in FIG. 1 , as a preferred embodiment of the present invention, the crossbar 3 is a rectangular member, and the column 11 is a square tube.

[0017] The crossbar 3 is a rectangular member with an M-shaped steel bar 5 welded on one side. One side of the trampoline spring is hooked and hung on the M-shaped steel bar 5. Connection holes are opened at both ends of the crossbar 3 and are connected to the connector 2 on the column 11; the column 11 is a square tube, and the connector 2 is welded on the upper side of the column 11 to connect the crossbar 3. An oblique support 13 is welded in the middle of the column 11, and a base plate 12 with mounting holes is welded at the bottom; the fixing bolts 4 are used to connect the column 11 and the crossbar 3; the expansion bolts 4 are used to fix the column 11.

[0018] The installation process of this trampoline structure is as follows: First, the columns 11 are placed in the corresponding positions. The columns 11 are connected with cross bars 3 and fixing bolts 4. After the four upper cross bars 3 are fixed, the base plate 12 and the diagonal supports 13 are fixed to the ground with expansion bolts 14, thereby fixing the columns 11. The mounting holes of the base plate 12 and the diagonal supports 13 can be filled with the corresponding number of expansion bolts 14 according to actual needs, and they do not have to be filled. After the expansion bolts 14 are tightened, one end of the spring hook can be hooked to the M-shaped steel bar 5, and the other end of the spring hook can be hooked to the trampoline surface, thus completing the installation of the entire trampoline. This structure uses expansion bolts 4 to fix the columns 11, eliminating the need for bottom cross bars and internal cross supports, making installation more convenient.

[0019] In addition, if the trampoline is large, the desired effect can be achieved by simply adding a supporting mechanism 1 in the middle of the crossbar 3 according to actual conditions, while ensuring the stability of the structure.

[0020] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
