Description

Technical Field

[0001] This utility model relates to the field of pressure sensor technology, and more specifically to a connection structure for a pressure sensor. Background Technology

[0002] A pressure sensor is a device that can sense pressure and convert it into electrical energy. It is widely used in industrial, medical, automotive and consumer fields. In physics teaching experiments, pressure sensors are often used to verify the impact force when an object falls.

[0003] Currently, the common method for installing and connecting pressure sensors is a fixed installation, where the pressure sensor's mounting base is fixed to the surface of the housing. This results in a fixed angle for the sensor's detection surface. In such cases, it is difficult to make flexible adjustments when it is necessary to test and verify impact forces at different angles and directions, leading to incomplete test results.

[0004] In view of this, the present invention proposes a connection structure for a pressure sensor that facilitates changing direction. Utility Model Content

[0009] As a further description of the above technical solution: by setting the mounting screw, the base and the experimental table can be firmly fixed.

[0010] Furthermore, the connecting platform is rotatably connected to the top of the vertical shaft, and an orientation positioning component is provided between the base and the connecting platform. The orientation positioning component includes a plurality of limiting holes arranged in a circumferential array on the upper surface of the base. The surface of the connecting platform is threaded with threaded set screws, and the positions of the threaded set screws and the limiting holes correspond to each other.

The bottom end of the protective post extends to the bottom side of the guide plate and rests on the sensing end surface of the sensor body.

[0015] As a further description of the above technical solution: by setting up protective components, the movement path of the guide plate is guided and restricted by the guide post, and the bottom end of the protective post is placed on the sensing end surface of the sensor body.
