[0014] In order to make the technical means for realizing the utility model, creative features, objectives and effects easy to understand, the utility model is further explained below in conjunction with specific diagrams. In the description of the utility model, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, an integral connection or a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be internal communication between two components.

[0015] Example 1

[0016] like Figure 1-3The shown device is a stepless continuous load variable mechanism with real-time feedback of displacement and load, comprising a loading motor 1, a sliding module 2, a loading mounting seat 6 and a mounting base plate 11, on which the sliding module 2 is mounted, the input end of the sliding module 2 is connected to the loading motor 1, and the output end of the sliding module 2 is connected to the loading mounting seat 6. When the loading motor 1 is started, the sliding module 2 can be driven to move up and down, thereby driving the loading mounting seat 6 to move up and down, a loading conduction mechanism is mounted on the loading mounting seat 6, and a detection unit for obtaining displacement feedback is provided on the loading mounting seat 6.

[0017] In this embodiment, the loading transmission mechanism includes a pressure sensor 7, a loading connecting rod 8, a pressure needle 9 and a connecting piece 10. The loading mounting seat 6 is connected to the pressure sensor 7 through the connecting piece 10. The lower end of the pressure sensor 7 is connected to the loading connecting rod 8. The lower end of the loading connecting rod 8 is connected to the pressure needle 9. The force is applied by the loading motor 1, and the pressure needle 9 is driven to reciprocate by the sliding module 2. The force is applied to the object to be measured by the loading mounting seat 6, and the force data is obtained by the pressure sensor 7. The application and data feedback of small force to large force are realized. The force is stably transmitted by the loading connecting rod 8, and loading can be implemented by the pressure needle 9.

[0018] Furthermore, the sliding module 2 includes a screw rod 12, a slide rail 13 and a slider 14. The screw rod 12 is installed on the mounting base plate 11. The slide rail 13 is located on one side of the screw rod 12. The slide rail 13 is connected to the mounting base plate 11. The slider 14 is connected to the loading mounting seat 6. The slider 14 is slidably connected to the slide rail 13. The side of the loading mounting seat 6 away from the slide rail 13 is connected with a connecting piece Ⅰ15. The connecting piece Ⅰ15 is sleeved on the outer wall of the screw rod 12. The top of the mounting base plate 11 is connected to the bracket 16. The loading motor 1 is installed on the bracket 16. The screw rod 12 is connected to the loading motor 1. After the loading motor 1 is started, it drives the screw rod 12 to rotate. The connecting piece Ⅰ15 moves up and down along the outer wall of the screw rod 12, driving the loading mounting seat 6 to move up and down. At this time, the slider 14 installed on one side of the loading mounting seat 6 will move along the slide rail 13, so that the loading mounting seat 6 will not shake left and right when sliding. Limit sensors 5 are provided at both ends of the slide rail 13. When the slider 14 contacts the limit sensor 5 when moving up and down, the slider 14 will stop, so that the slider 14 can only slide between the two limit sensors 5, and the slider 14 is limited to prevent it from sliding out of the slide rail 13, thereby ensuring the verticality and stability of the up and down movement of the pressure needle 9 and making the load change process more continuous.

[0019] Example 2

[0020] A further improvement on the basis of Example 1 is that Figure 1A stepless continuous load changing mechanism device with real-time feedback of displacement and load is shown, and the detection unit includes a displacement sensor 3 and a grating ruler 4. The displacement sensor 3 is installed between the loading mounting seat 6 and the pressure sensor 7, and the grating ruler 4 is installed on the mounting base plate 11. The displacement is fed back in real time by the displacement sensor 3 in cooperation with the grating ruler 4, so that accurate feedback can be obtained during the load changing process, thereby improving the adjustment accuracy.

[0021] The process flow and working principle of the utility model are as follows: the device starts the loading motor 1 to drive the sliding module 2 to drive the loading mounting seat 6 to move up and down. The up and down movement of the loading mounting seat 6 will drive the loading connecting rod 8 and the pressure needle 9 to move up and down. The grating ruler 4 and the displacement sensor 3 can be used to perform real-time displacement feedback. The pressure sensor 7 is used to realize the application and data feedback of small force values ​​to large force values, so that accurate feedback can be obtained during the load change process, and the adjustment accuracy is improved. By installing the slide rail 13 on the installation base plate 11 and the slider 14 on the loading mounting seat 6, due to the sliding cooperation between the slider 14 and the slide rail 13, the loading mounting seat 6 can only move up and down along the slide rail 13, and then limit sensors 5 are respectively arranged at both ends of the slide rail 13, so that the slider 14 will stop moving when it contacts the limit sensor 5, and the slider 14 is limited to ensure the verticality and stability of the up and down movement of the pressure needle, so that the load change process is more continuous, which has the effects of improving the load change accuracy, realizing the continuous load change process, and enhancing the portability of operation.
