Figure 2 for Figure 1 Schematic diagram of the top view of the measuring device. Figure 3 for Figure 2 Schematic diagram of the cross-sectional structure of the measuring device in the AA direction. Figure 4 for Figure 3An enlarged cross-sectional view of part B of the measuring device. Figure 1 , 2 As shown in , 3 and 4, the utility model proposes a measuring device. The measuring device in the utility model includes a support frame 10, a buffer 20, a platform 30 and a first positioning member 40, the buffer 20 abuts against one side of the support frame 10, a first positioning groove 12 is provided on the side of the support frame 10 facing the buffer 20, a second positioning groove 21 is provided on the side of the buffer 20 facing the support frame 10, the depth of the first positioning groove 12 and the depth of the second positioning groove 21 are both set along the first direction, the platform 30 abuts against the side of the buffer 20 away from the support frame 10, the first positioning member 40 is plugged into the first positioning groove 12 and the second positioning groove 21, and the support frame 10 and the platform 30 can move relative to each other along the first direction, and the first direction is the arrangement direction of the support frame 10 and the platform 30.

[0036] According to the measuring device of the utility model, when the measuring device is affected by the vibration of the external environment, it will be transmitted to the platform 30 through the support frame 10. Since the buffer 20 abuts between the support frame 10 and the platform 30, it is equivalent to separating the support frame 10 and the platform 30, and making the platform 30 float on the support frame 10. The buffer 20 can buffer the vibration impact of the support frame 10 on the platform 30 and improve the stability of the platform 30. In addition, the first positioning member 40 is respectively inserted into the second positioning groove 21 of the buffer 20 and the first positioning groove 12 of the support frame 10, and the buffer 20 and the support frame 10 can be limited in other directions perpendicular to the first direction to ensure that the buffer 20 will not be offset. The platform 30 and the support frame 10 of the utility model are abutted by the buffer 20, which is equivalent to a flexible connection between the platform 30 and the support frame 10, which can make the buffer 20 fully play the role of buffering and improve the shock absorption effect. The platform 30 in this embodiment can be a measuring platform.

[0037] In some embodiments of the present invention, Figure 4 As shown, along the first direction, the sum of the depth of the first positioning groove 12 and the depth of the second positioning groove 21 is greater than the length of the first positioning member 40. In this embodiment, when the support frame 10 is affected by the vibration of the external environment, the support frame 10 will reciprocate along the first direction, and the first positioning member 40 can not only limit the buffer 20 and the support frame 10, but also, because the sum of the depth of the first positioning groove 12 and the depth of the second positioning groove 21 is greater than the length of the first positioning member 40, the first positioning member 40 will not abut against the bottom of the second positioning groove 21 of the buffer 20 during the vibration process, thereby interfering with the deformation of the buffer 20, thereby improving the reliability of the buffer 20.

[0038] In some embodiments of the present invention, there are multiple first positioning grooves 12, multiple second positioning grooves 21, and multiple first positioning members 40. The number of first positioning grooves 12, the number of second positioning grooves 21, and the number of first positioning members 40 are the same. The first positioning grooves 12 and the second positioning grooves 21 correspond to each other one by one, and each first positioning member 40 is respectively inserted into a first positioning groove 12 and a second positioning groove 21. In this embodiment, the provision of multiple positioning members, multiple first positioning grooves 12, and multiple second positioning grooves 21 can further position the buffer member 20, ensuring that the buffer member 20 will not be offset when the support frame 10 is subjected to external vibration, thereby improving the positioning effect of the buffer member 20.

[0039] In some embodiments of the present invention, Figure 4 As shown, the measuring device further includes a second positioning member 50, a third positioning groove 33 is provided on the side of the platform 30 facing the buffer 20, a fourth positioning groove 22 is provided on the side of the buffer 20 facing the platform 30, the depth of the third positioning groove 33 and the depth of the fourth positioning groove 22 are both set along the first direction, and the second positioning member 50 is respectively plugged into the third positioning groove 33 and the fourth positioning groove 22. In this embodiment, the second positioning member 50 is respectively plugged into the fourth positioning groove 22 of the buffer 20 and the third positioning groove 33 of the platform 30. Since the buffer 20 has been limited and positioned by the first positioning member 40, the platform 30 can be limited and positioned with the buffer 20 by the second positioning member 50, so that the support frame 10, the buffer 20 and the platform 30 can only move along the first direction, ensuring that the measuring device will not be offset in other directions perpendicular to the first direction.

[0040] In some embodiments of the present invention, Figure 4 As shown, along the first direction, the sum of the depth of the third positioning groove 33 and the depth of the fourth positioning groove 22 is greater than the length of the second positioning member 50. In this embodiment, when the support frame 10 is affected by the vibration of the external environment, the support frame 10 will reciprocate along the first direction and transmit it to the buffer 20, and the buffer 20 will also deform along the first direction. At this time, the second positioning member 50 can not only limit the buffer 20 and the platform 30, but also because the sum of the depth of the third positioning groove 33 and the depth of the fourth positioning groove 22 is greater than the length of the second positioning member 50, the second positioning member 50 will not abut against the bottom of the third positioning groove 33 of the platform 30 during the vibration process, and thus the force of the second positioning member 50 will not be transmitted to the platform 30, thereby improving the stability of the platform 30.

[0041] In some embodiments of the present invention, there are multiple third positioning grooves 33, multiple fourth positioning grooves 22, and multiple second positioning members 50. The number of fourth positioning grooves 22, the number of third positioning grooves 33, and the number of second positioning members 50 are the same. The third positioning grooves 33 and the fourth positioning grooves 22 correspond one to one, and each second positioning member 50 is respectively inserted into a third positioning groove 33 and a fourth positioning groove 22.

[0042] In some embodiments of the present invention, Figure 1 and 2 As shown, the measuring device is provided with a fixing hole 31, and the fixing hole 31 sequentially penetrates the platform 30, the buffer 20 and the support frame 10 along the first direction. In this embodiment, when the measuring device needs to be moved as a whole, bolts and other connecting parts need to be fastened with the fixing holes 31 to ensure the stability of the platform 30, the buffer 20 and the support frame 10 during the movement. After reaching the measuring station, the bolts and other connecting parts are removed, and then the measurement and other operations can be carried out.

[0043] In some embodiments of the present invention, Figure 1 and 2 As shown, there are multiple fixing holes 31, multiple buffers 20, and multiple buffers 20 are arranged at intervals around the axial direction of the support frame 10, and the buffers 20 correspond to the fixing holes 31 one by one. In this embodiment, there are four buffers 20, and the four buffers 20 are respectively arranged at the four corners of the support frame 10, so that the platform 30 and the support frame 10 can be separated and connected only by the buffers 20, which can improve the shock absorption effect of the measuring device.

[0044] Specifically, in this embodiment, the number of fixing holes 31 is consistent with that of the buffer 20. In this embodiment, four fixing holes 31 are provided, one on each buffer 20. During the movement of the measuring device, the stability of the platform 30, the buffer 20 and the support frame 10 can be ensured.

[0045] In some embodiments of the present invention, Figure 1 As shown, at least one stopper 11 is provided on the side of the support frame 10 facing the platform 30, and at least one stopper groove 32 is provided on the platform 30, and each stopper 11 is located in a stopper groove 32. In this embodiment, the platform 30 is a marble platform 30, and the side of the platform 30 away from the buffer 20 is used to place the device body. The cooperation of the stopper 11 and the stopper groove 32 can determine and limit the position of the platform 30 and the support frame 10, thereby improving the relative position accuracy of the platform 30 and the support frame 10.

[0046] In some embodiments of the present invention, Figure 1As shown, along the first direction, the platform 30 has a first surface on the side facing the support frame 10, and the support frame 10 has a second surface on the side facing the platform 30, and the first surface and the second surface are arranged at intervals. In this embodiment, the platform 30 and the support frame 10 are abutted by four buffers 20, and the remaining positions are provided with gaps, which can separate the support frame 10 and the platform 30, and make the platform 30 float on the support frame 10 through the buffer 20, and the buffer 20 can buffer the vibration impact of the support frame 10 on the platform 30, thereby improving the stability of the platform 30.

[0047] Furthermore, in this embodiment, the buffer component 20 is a shock-absorbing pad made of a polymer material.
