Description

Technical Field

[0001] The utility model relates to the field of protective spring nets, in particular to a training trampoline with a double-layer inner protective spring net. Background Art

[0002] Trampoline training is mainly aimed at improving athletes' gymnastics skills and aerial performance on the trampoline. Trampoline sports combine multiple elements such as gymnastics, skills and jumping.

[0003] During trampoline training, as trainees pursue higher jumping heights, wearing safety ropes often becomes an obstacle for them to freely display and complete various movements. Higher jumping heights not only limit the smoothness and beauty of the movements, but also increase safety risks. Specifically, when the jumping height increases, the trainees' stay time in the air is also extended accordingly, which means that they will be affected by the stronger rebound force of the trampoline when falling, causing them to bounce higher. This continuous high bounce not only increases the impact on key parts such as the ankles, knees and spine, but also increases the potential risk of injury due to loss of balance.

[0004] Therefore, it is necessary to propose a training trampoline with a double-layer inner liner protective spring net to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a training trampoline with a double-layer inner protective spring net to solve the problem that when the jumping height increases, the trainees' stay time in the air is also prolonged accordingly, which means that they will be affected by a stronger rebound force of the trampoline when falling, resulting in higher jumping. Such continuous high jumping not only increases the impact force on key parts such as ankles, knees and spine, but also increases the potential risk of injury due to loss of balance.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a training trampoline with a double-layer inner shell protective spring net, comprising a support frame and a protective spring net, wherein the protective spring net is fixedly arranged on the inner wall of the support frame, and the protective spring net is arranged in two layers, the upper and lower protective spring nets including an upper protective spring net and a lower protective spring net;

[0007] A protective net is fixedly provided on the surface of the support frame, a position sensor is fixedly provided on the inner wall of the protective net, an airbag liner is fixedly provided between the upper protective elastic net and the lower protective elastic net, an exhaust pipe is connected to the side of the airbag liner close to the lower protective elastic net, the exhaust pipe passes through the lower protective elastic net, an air pump is fixedly provided on the bottom of the support frame, an output end of the air pump is connected to an air intake pipe, and the air intake pipe passes through the lower protective elastic net and is communicated with the inside of the airbag liner.

[0008] Preferably, a solenoid valve is fixedly provided on the inner wall of the exhaust pipe.

[0009] Preferably, a plurality of protrusions are equidistantly and fixedly arranged on the surface of the upper protective elastic net.

[0010] Preferably, an elastic inlet is opened on one side of the protective net.

[0011] Technical effects and advantages of the utility model:

[0012] 1. The utility model, through the air bag liner placed in the middle of the elastic net, can more effectively manage the trainee's jumping height during trampoline training. When the trainee jumps to a safe position exceeding the preset position of the position sensor, the air bag liner can be automatically controlled to discharge part of the gas, thereby appropriately reducing the elasticity of the protective net, and at the same time reducing the height of the trainee being further bounced upward, reducing the impact force when the trainee falls, and avoiding the risk of injury caused by excessively high jumping height;

[0013] 2. When the trainer's jumping height remains within the safe range detected by the position sensor, the position sensor will drive the air pump to work and deliver the gas to the airbag liner through the air inlet pipe. At this time, the solenoid valve will remain closed to ensure that the gas enters the airbag liner smoothly, restoring its original elasticity to maintain the stability and elasticity of the trampoline.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The utility model provides Figure 1 - Figure 3 The training trampoline with a double-layer inner protective spring net shown includes a support frame 1 and a protective spring net 2. The protective spring net 2 is used for trainees to perform jumping training. The protective spring net 2 is fixedly arranged on the inner wall of the support frame 1. It is a prior art and will not be described in detail here.

[0020] In order to reduce the sense of restraint for the trainee, a protective net 5 is fixedly provided on the surface of the support frame 1 without using a safety rope, and an elastic entrance 12 is opened on one side of the protective net 5 so that the trainee can easily enter and exit the trampoline.

[0021] The protective elastic net 2 is arranged in two layers, the upper and lower layers, and the protective elastic net 2 includes an upper protective elastic net 3 and a lower protective elastic net 4. A plurality of protrusions 11 are fixedly and equidistantly arranged on the surface of the upper protective elastic net 3, so that when the foot steps on the upper protective elastic net 3, when the trainee steps on it, they can increase the friction between the foot and the protective elastic net 2, providing a more stable support for the trainee.

[0022] A position sensor 6 is fixedly arranged on the inner wall of the protective net 5, an airbag liner 7 is fixedly arranged between the upper protective elastic net 3 and the lower protective elastic net 4, an exhaust pipe 8 is connected to the side of the airbag liner 7 close to the lower protective elastic net 4, the exhaust pipe 8 passes through the lower protective elastic net 4, and an electromagnetic valve is fixedly arranged on the inner wall of the exhaust pipe 8. When the trainee bounces to a safe position exceeding the preset safety position of the position sensor 6, a part of the gas in the airbag liner 7 can be automatically controlled to be discharged, thereby appropriately reducing the elasticity of the protective elastic net 2, and at the same time reducing the height to which the trainee is continuously bounced upward, reducing the impact force when the trainee falls, and avoiding the risk of injury due to excessively high bouncing height.

[0023] When the jumping height of the trainee is kept within the safe range detected by the position sensor 6, an air pump 9 is fixedly installed at the bottom of the support frame 1, and the output end of the air pump 9 is connected to the air intake pipe 10. The air intake pipe 10 passes through the lower protective elastic net 4 and is connected to the inside of the airbag liner 7. The position sensor 6 will drive the air pump 9 to work and transport the gas to the airbag liner 7 through the air intake pipe 10. At this time, the solenoid valve will remain closed to ensure that the gas enters the airbag liner 7 smoothly, so that it can restore its original elasticity to maintain the stability and elasticity of the trampoline.
