Description

Technical Field

[0001] This utility model belongs to the field of square trampoline technology, specifically relating to a square trampoline with reinforced spring steel plate foot tubes. Background Technology

[0002] Square trampolines are a common type of fitness and recreational equipment, popular for their large jumping space and stable user experience. Most square trampolines have a rectangular structure with a long and short side in their main frame. In practical use, the long side bears the tension of the springs and trampoline for extended periods, generating significant stress on the frame and making it prone to deformation. This deformation not only affects the trampoline's appearance, reducing its overall aesthetic appeal, but also negatively impacts its performance. For example, deformation can lead to an uneven surface, affecting the jumping experience, increasing the risk of injury, accelerating component wear, shortening the trampoline's lifespan, increasing usage and maintenance costs, and limiting its applicability. Summary of the Invention

[0003] The purpose of this invention is to provide a square trampoline with reinforced spring steel plate legs that has a reasonable structural design and is conducive to improving the stability of use.

[0004] The technical solution to achieve the purpose of this utility model is a square trampoline with reinforced spring steel plate foot tubes, including a square frame composed of two long frame sides and two short frame sides, and a trampoline cloth set on the square frame by springs. Several reinforced spring plate foot tubes are fixed at the bottom of the two long frame sides.

[0005] The reinforced spring plate foot tube includes a foot bend, an L-shaped side bend fixed to both ends of the foot bend, a fixed connecting tube fixed to the top of the L-shaped side bend, and a spring plate set at the end of the foot bend and the upper part of the vertical rod of the L-shaped side bend.

[0006] The fixed connecting pipe is inserted into the bottom surface of the long frame and fixed with screws.

[0007] A further preferred embodiment is that the spring plate is compressed into an arc shape to store force, and its two ends are respectively fixed to the end of the foot bend and the upper part of the vertical rod of the L-shaped side bend by screws.

[0008] A further preferred embodiment is that the connection between the L-shaped side bend and the foot bend is an upward arch shape.

[0009] A further preferred embodiment is that: edge tubes are fixed at both ends of the two long frame sides;

[0010] The side foot tube is the structure after removing the spring plate from the foot tube with a fixed spring plate.

[0011] A further preferred embodiment is that the number of the reinforcing spring plate foot tubes is two, three, or four.

[0012] A further preferred embodiment is that the spring plate is a flat steel plate, and the two ends of the flat steel plate are machined with arc-shaped mounting positions.

[0013] A further preferred embodiment is that a fixing installation port is provided on the side wall of the fixing connecting pipe.

[0014] This utility model has positive effects: its structure is reasonably designed, with several reinforcing spring plate foot tubes fixed at the bottom of the long frame side, and spring plates set at the connection between the L-shaped side bend and the foot bend. Through the cooperation of the spring plates with the L-shaped side bend and the foot bend, the deformation coefficient of the foot bend and the L-shaped side bend is corrected by the reverse force of the spring plates during use, effectively preventing deformation in the middle of the trampoline, thereby improving the stability of the trampoline structure, ensuring the reliability of the trampoline, avoiding usage obstacles caused by deformation of the long frame side, and it is easy to assemble and disassemble, which helps to reduce production costs and installation difficulty, and has strong applicability.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0021] See Figures 1 to 3As shown, a square trampoline with reinforced spring steel plate foot tubes includes a square frame composed of two long frame sides 1 and two short frame sides 2, and a trampoline 3 set on the square frame by springs. Several reinforced spring plate foot tubes 4 are fixed to the bottom of the two long frame sides. In this embodiment, the number of reinforced spring plate foot tubes is two, three, or four. The trampoline is a conventional structure in the prior art, and its application is simply simplified. The long and short frame sides are also conventional structures in the prior art, and therefore are not described in detail, but are simply applied.

[0022] In practical applications, the reinforced spring plate foot tube includes a foot bend 41, an L-shaped side bend 42 fixed at both ends of the foot bend, a fixed connecting pipe 43 fixed at the top of the L-shaped side bend, and a spring plate 44 set at the end of the foot bend and the upper part of the vertical rod of the L-shaped side bend. In this embodiment, the spring plate is a flat steel plate, and the two ends of the flat steel plate are processed with arc-shaped mounting positions.

[0023] During installation, the spring plate is compressed into an arc shape to store energy, and its two ends are fixed to the ends of the foot bend and the upper part of the vertical rod of the L-shaped side bend with screws, respectively. At this time, elastic deformation potential energy is generated inside the spring plate, generating a reverse force. The screws fix the connection, which can improve the stability and reliability of the connection. The spring plate is tightly connected with the L-shaped side bend and the foot bend to form an integral reinforced structure. Since the short frame side is subjected to relatively small forces during use, it will not deform. Therefore, the short side does not need to be reinforced with a spring plate foot tube, which can reduce processing costs and does not increase the weight of the trampoline, improving rationality and economy. Furthermore, the reinforcement of the spring plate foot tube can effectively prevent deformation of the long side and ensure the stability of the trampoline structure.

[0024] During installation, the fixing connector is inserted into the bottom surface of the long frame side and secured with screws. The connection between the L-shaped side bend and the foot bend is an upward arched design.

[0025] In practical applications, side foot tubes 5 are fixed at both ends of the two long frame sides; the side foot tubes are the structure after removing the spring plates from the fixed spring plate foot tubes. A fixing installation port 6 is provided on the side wall of the fixing connecting tube. This improves the stability and reliability of the installation.

[0026] Its working principle is as follows: When the trampoline is put into use, the tension generated by the springs and the trampoline acts on the square frame, especially the long frame edges, causing the L-shaped side bends to be subjected to outward tensile force, thus creating a deformation tendency. At this time, the spring plate installed on the L-shaped side bend, due to being compressed into an arc shape, has a tendency to return to its original shape, generating a force opposite to the deformation direction of the L-shaped side bend, i.e., a reverse force. This reverse force can offset part of the deformation force generated by the springs and the trampoline, correcting the deformation of the L-shaped side bend, reducing the deformation coefficient of the L-shaped side bend, and thus effectively preventing deformation in the middle of the square frame. In this way, the reinforced spring plate foot tubes and the square frame cooperate with each other to jointly withstand various external forces during use, ensuring that the trampoline maintains a stable structure and good performance during long-term use.

[0027] This utility model has positive effects: its structure is reasonably designed, with several reinforcing spring plate foot tubes fixed at the bottom of the long frame side, and spring plates set at the connection between the L-shaped side bend and the foot bend. Through the cooperation of the spring plates with the L-shaped side bend and the foot bend, the deformation coefficient of the foot bend and the L-shaped side bend is corrected by the reverse force of the spring plates during use, effectively preventing deformation in the middle of the trampoline, thereby improving the stability of the trampoline structure, ensuring the reliability of the trampoline, avoiding usage obstacles caused by deformation of the long frame side, and it is easy to assemble and disassemble, which helps to reduce production costs and installation difficulty, and has strong applicability.

[0028] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0029] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
