[0025] Please see Figure 1-4This utility model provides an embodiment of a measuring probe structure, including a head 1. The bottom outer surface of the head 1 is provided with an external thread 13, which allows for threaded connection with an external structure. This facilitates the installation of the measuring probe on an external drive structure, ensuring its normal operation. The tail end of the head 1 is provided with an internal thread 2, and the bottom end of the head 1 is provided with an inner seat 3. The top outer wall of the inner seat 3 is provided with a first thread 4 that matches the internal thread 2. The inner seat 3 and the head 1 are detachably connected by threads. This structural design, through the detachable connection between the inner seat 3 and the head 1 by threads, facilitates the assembly and disassembly of the inner seat 3 and the head 1 in actual use. This allows for quick threaded assembly and disassembly, enabling the opening of the inner seat of the measuring probe for maintenance or troubleshooting, resulting in good practical performance.

[0026] Furthermore, the inner seat 3 has a second thread 5 on its outer wall in the middle. An outer shell 6 is fitted over the inner seat 3, and the outer shell 6 is detachably connected to the inner seat 3 via the second thread 5. This design allows the outer shell 6 to be fitted over the inner seat 3, providing external protection and preventing exposure of the internal structure of the measuring probe, thus improving the protection of the inner seat 3. The detachable connection between the outer shell 6 and the inner seat 3 via the second thread 5 facilitates easy disassembly of the outer shell 6 during actual use. By using the threaded end 1 for disassembly, the measuring probe structure of this utility model can be disassembled into multiple parts, which can effectively separate and disassemble the probe structure, thereby facilitating the disassembly and maintenance of the measuring probe. The disassembly and maintenance work is more convenient, effectively reducing the difficulty of maintenance and repair work. It has the practical effect of quick assembly and quick disassembly. Compared with the traditional one-piece probe structure, this utility model can be quickly assembled and disassembled, thereby effectively improving the speed of maintenance and repair work, saving more time and effort, and effectively improving the overall practicality of the structure.

[0027] In this embodiment, a reset seat 7 is provided at the center of the inner seat 3. The reset seat 7 is slidably installed inside the seat. A syringe 9 is fixedly installed at the bottom end of the reset seat 7. The syringe has syringe threads on its inner wall.

[0028] Furthermore, in order to ensure the normal use of the probe 10, the probe 10 is connected to the inside of the syringe 9 through a syringe thread.

[0029] This structural design ensures the normal use of the measuring probe through the set probe 10. That is, when the measuring probe of this utility model is displaced under the action of the external driving structure, the probe 10 can first touch the measuring product. As it continues to descend, the probe 10 will push the reset seat 7 at the top under the action of the driving pressure, thereby causing the reset seat 7 to move upward.

[0030] The probe 10 of this utility model can be connected to the syringe 9 by means of threaded installation. Therefore, the probe 10 can be effectively disassembled, maintained or replaced during use, which facilitates the replacement and maintenance of the probe 10, improves the convenience of the structure, and allows for targeted disassembly and replacement when the probe 10 is damaged, without having to discard the entire probe assembly, thereby improving the utilization rate of the structure and avoiding structural waste.

[0031] In this embodiment, please refer to the appendix to the specification for details. Figure 2 as well as Figure 4 As shown, a reset spring 8 is fixedly installed on the upper surface of the reset seat 7, and the top end of the reset spring 8 is fixedly connected to the pressure signal transmission seat (shown in the figure, but not marked) of the inner seat 3.

[0032] When the reset seat 7 moves upward, it will compress the reset spring 8. At the same time, the pressure on the probe 10 can be sensed and transmitted through the pressure signal transmission seat, so that the pressure electrical signal can be transmitted to the external measurement system, ensuring the normal use effect of the measurement probe of this utility model.

[0033] The reset spring 8 can drive the reset seat 7 and the probe 10 to move downwards and reset after the pressure is removed, ensuring the normal operation of the next measurement.

[0034] In this embodiment, in order to provide a certain guiding effect for the displacement of the reset seat 7, please refer to the appendix of the specification for details. Figure 3 As shown, a number of guide grooves 11 are provided on the inner wall of the middle part of the inner seat 3. The guide grooves 11 are distributed circumferentially at equal intervals through the center point of the inner seat 3, and the guide grooves 11 are evenly surrounding the outside of the reset seat 7.

[0035] Furthermore, a guide post 12 adapted to the guide groove 11 is fixedly installed on the outer surface of the reset seat 7. The top ends of several guide posts 12 are respectively inserted into the corresponding guide grooves 11, and the guide posts 12 are slidably connected to the wire groove.

[0036] With this structural design, when the reset seat 7 is moved upward or downward to reset, the guide post 12 on its outer wall can slide up and down in the guide groove 11. In this way, the guide post 12 and the guide groove 11 work together to provide a certain displacement guidance for the vertical displacement of the reset seat 7, so that the vertical displacement effect remains linear, avoids displacement deviation, and improves the measurement accuracy of the measuring probe.

[0037] Working principle: Users can use the measuring probe of this utility model through conventional methods. This utility model has an external thread 13 on the outside of the end head 1. The external thread 13 can be threaded to the external structure, so as to facilitate the installation of the measuring probe of this utility model on the external drive structure, ensuring its normal use effect, and the measuring probe of this utility model can be connected to the external measuring system through the wire.

[0038] When the measuring probe of this utility model is displaced under the action of the external driving structure, the probe 10 can first touch the measuring product. As it continues to descend, the pressure will be transmitted upward through the reset seat 7 and the reset spring 8, and finally transmitted through the pressure signal transmission seat. Thus, the pressure electrical signal can be transmitted to the external measuring system, ensuring the normal use effect of the measuring probe of this utility model. This is the basic working principle of the measuring probe product, which is a mature and publicly available prior art product and solution. This specification will not elaborate further.

[0039] This utility model allows for a detachable connection between the inner seat 3 and the end head 1 via threads. In actual use, it facilitates the assembly and disassembly of the inner seat 3 and the end head 1, enabling quick thread assembly and disassembly. This allows the opening of the inner seat of the measuring probe, facilitating maintenance or troubleshooting of the measuring probe, and demonstrates good practical performance.

[0040] Meanwhile, the outer shell 6 can be fitted over the inner base 3, thus providing external protection for the inner base 3 and preventing the internal structure of the measuring probe from being exposed, thereby improving the protection effect of the inner base 3. The outer shell 6 and the inner base 3 are detachably connected by a No. 2 thread 5, which allows for easy disassembly of the outer shell 6 during actual use. By using the thread on the end head 1 for disassembly, the measuring probe structure of this utility model can have a multi-body disassembly effect, which can effectively separate and disassemble the probe structure, thereby facilitating the disassembly and maintenance of the measuring probe. The disassembly and maintenance work is more convenient, effectively reducing the difficulty of maintenance and repair work, and has the practical effect of quick assembly and disassembly. Compared with the traditional one-piece probe structure, this utility model can be quickly assembled and disassembled, thereby effectively improving the speed of maintenance and repair work, saving time and effort, and effectively improving the overall practicality of the structure.

[0041] Furthermore, the probe 10 of this utility model can be connected to the syringe 9 by means of threaded installation. Therefore, the probe 10 can be effectively disassembled, maintained, or replaced during use, which facilitates the replacement and maintenance of the probe 10, improves the convenience of the structure, and allows for targeted disassembly and replacement when the probe 10 is damaged, without having to discard the entire probe assembly, thereby improving the utilization rate of the structure and avoiding structural waste.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
