Background
The movable probe is an important testing tool, the movable probe is driven by the moving mechanism to move and acquire data, and the maximum size of the movable probe pressure-guiding structure does not exceed the size of the displacement mechanism mounting hole because the movable probe needs to pass through the displacement mechanism mounting hole when in use, so that the size of the pressure-guiding structure is limited.
Therefore, most of the current pressure guiding structures of the movable pressure guiding probe are designed to adopt a plurality of slender pressure guiding pipes which are connected by rubber pipes, as shown in fig. 1. In the prior art, the pressure guiding pipe 3 is made of a stainless steel pipe, one end of the pressure guiding pipe passes through the guide pipe 1 to be connected with the measuring point 5, the other end of the pressure guiding pipe is connected with the pressure guiding connection nozzle 4 in a welding mode, and a plugging cover 2 is arranged at one end, back to the measuring point 5, of the guide pipe 1 to plug the guide pipe and fix the pressure guiding pipe 3. When the movable probe is used, the axial direction of the pressure guiding pipe 3 is required to be adjusted to be parallel to the axial direction of the guide pipe 1, then the pressure guiding joint nozzle 4, the pressure guiding pipe 3 and the guide pipe 4 penetrate through the displacement mechanism mounting hole, and the pressure guiding joint nozzle 4 is connected with a test device through a rubber pipe.
The above scheme has the following disadvantages:
1. because the number of the movable probe measuring points 5 is large, and correspondingly, a large number of the pressure guiding pipes 3 are connected with the movable probe measuring points, different lengths of the pressure guiding pipes 3 need to be designed for avoiding mutual interference among the pressure guiding connecting nozzles 4, and under the condition of large number of the pressure guiding pipes, part of the pressure guiding pipes 3 are long, so that the pressure guiding pipes are easy to bend and even break.
2. After multiple use, the slender pressure guiding pipe 3 made of the stainless steel pipe can generate unrecoverable deformation, so that the slender pressure guiding pipe is difficult to penetrate through the mounting hole of the displacement mechanism, and the accuracy of experimental test can be influenced.
3. When the pressure-sensitive adhesive tape is used, the joint of the pressure-sensitive adhesive nozzle 4 and the rubber tube is easy to leak air, and the pressure-sensitive adhesive tape is complex to assemble and disassemble.
