TECHNICAL FIELD
[0001] The utility model relates to the technical field of pneumatic force measurement, especially to a branch pipe pneumatic force measurement experiment table. BACKGROUND
[0002] The branch pipe pneumatic force measurement experiment table is an experimental equipment for measuring air pressure and force, which is usually composed of an air pressure control device, a force sensor and a data acquisition device, etc. It can test and analyze various physical phenomena and mechanical properties related to air pressure and force, and is widely used in the fields of aerospace, mechanical engineering, automobile manufacturing, etc. Through the experiment table, the size and change of force under different air pressure conditions can be accurately measured, providing important experimental data support for related research and engineering design.
[0003] The branch pipe pneumatic force measurement experiment table works by generating stable air pressure through the air source device, accurately regulating through the branch pipe device, and transmitting the air pressure to the target test site.

The data acquisition device quickly captures the electrical signal, converts and presents the corresponding force value under the air pressure, realizing accurate measurement of air pressure and force.
[0004] In the prior art, some branch pipe pneumatic force measurement experiment tables have many deficiencies due to the existing experimental table air pipe fixing method.

Some complex fixing structures have improved stability, but the operation is complicated. When installing and removing the air pipe, the experimental personnel need to use multiple tools to complete multiple steps, which seriously affects the experimental efficiency. Some fixing methods that use bolts, nuts and complex clamps take too long to operate when adjusting or replacing the air pipe in an emergency, delaying the experimental process, causing gas leakage, affecting the accuracy of experimental data, and being difficult to adapt to air pipes of different specifications and materials. Therefore, a branch pipe pneumatic force measurement experiment table is proposed to solve the above problems. UTILITY MODEL CONTENTS
