Description

Technical Field

[0001] The present application belongs to the technical field of inflatable cushioning balls, and more specifically, relates to an inflatable rubber cushioning ball with a pressure sensing chip. Background Art

[0002] The rubber inflatable cushion ball is in a low pressure state under normal conditions. When it is squeezed by external force, the pressure increases and stores energy, absorbing the impact energy and playing a buffering role. Depending on the application of the cushion ball, different diameters of cushion balls are selected, and the initial pressure inside is different, generally 50-80kPa. This initial pressure must be maintained at ordinary times to ensure that it plays a safety protection role during use. Since the cushion ball is used less frequently at ordinary times, in order to prevent gas leakage under complex working conditions such as long-term placement or long-term exposure to sunlight on the ship, because the pressure gauge cannot be set on the cushion ball under normal conditions or during use, it is necessary to check the air pressure status regularly. Each inspection requires a pressure gauge to connect the air inlet duct, and some even need to pull out the air needle to connect the pipeline. After monitoring, it must be restored to its original state. Sometimes gas leakage occurs due to inadequate cleaning during the restoration, which is very troublesome. Utility Model Content

The backrest ball body 1 is connected between the inner flange 6 and the outer flange 7. Core shaft through holes 8 are provided at corresponding positions of the inner flange 6 and the outer flange 7. An outer core shaft 9 is inserted through the core shaft through hole 8.

Specifically, through the combined action of the inner flange 6 and the outer flange 7, the flange assembly 4 is fixed to the ball support, and then the eyebolt seat 5 is fixed to the flange assembly 4, thereby realizing the connection between the ball support and the eyebolt seat 5. It should be noted that the core shaft through holes 8 are provided on both the inner flange 6 and the outer flange 7, and the axial center positions of the core shaft through holes 8 on the inner flange 6 and the outer flange 7 correspond to each other.

A pressure sensing chip 12 is provided to detect the pressure inside the ball support, and at the same time, the temperature data inside the ball support can also be detected. It should be noted that in this embodiment, a terminal receiver is also provided to receive the signals sent by the pressure sensing chip 12. When the ball support is in use, the pressure sensing chip 12 detects the pressure, temperature and other data inside the ball support in real time, and transmits the data to the terminal receiver to realize the real-time monitoring of the data of the ball support during use. When not in use, it can also detect whether the ball support leaks air through the pressure sensing chip 12. A protective cover 11 is provided to protect the pressure sensing chip 12.

Through the cooperation of the stud 24 with the second through hole 16 and then the cooperation of the second nut 23 with the stud 24, the inner flange 6 and the outer flange 7 can be fixed to the ball support body 1. The two eyebolt seats 5 are linked to the mesh cover formed by the chain and the buffer pad 21, playing a role in protecting the ball support body.

[0028] Furthermore, in this embodiment, the number of the positioning pins 18 is three, and all three positioning pins 18 cooperate with the base ring sleeve.

[0029] In the technical solution selected in this embodiment, by setting three positioning pins 18 to cooperate with the base ring sleeve, the connection position of the lifting ring seat 5 can be restricted more stably.

[0030] Furthermore, in this embodiment, a sealing gasket 19 is also connected inside the shield 11.

[0031] In the technical solution adopted in this embodiment, the setting of the sealing gasket 19 can prevent the pressure sensing chip 12 from loosening during the impact on the ball, ensuring the stability of the operation of the pressure sensing chip 12.

[0032] It should be noted that in this embodiment, at the connection between the cover 15 and the inner core shaft body 10, and at one end of the connection between the inner core shaft body 10 and the outer core shaft 9, O-ring seals 22 are provided, which can prevent water from entering the inner core shaft body 10 and the connection between the inner core shaft body 10 and the outer core shaft 9, and can also prevent air leakage of the ball, further improving the reliability of the ball operation.
