[0024] Please refer to Figures 1-2 The structure diagram of a measuring device 100 provided by an embodiment of the utility model, the measuring device 100 is mainly used for the measurement of the height or thickness or depth of the product to be measured, and in actual application, it is mainly used for measuring the thickness of glass to prevent the surface of glass from being scratched.

[0025] In an embodiment, the measuring device 100 includes a carrier platform 10 and a measuring assembly 20 arranged on the carrier platform 10, and the measuring assembly 20 is used to measure the thickness of the product to be measured. The carrier platform 10 is usually a marble platform. The measuring assembly 20 usually includes a measuring head 21 used to contact the product to be measured and a measuring device 22 connected to the measuring head, and the measuring device 22 can analyze and display the measured value of the product to be measured.

[0026] In the prior art, the carrier platform 10 is directly used to place the product to be measured for measurement, and after the measurement of the measuring assembly 20, the surface of the product to be measured is easily scratched.

[0027] In an embodiment, the measuring device 100 includes a support device 30 arranged on the carrier platform 10, and the support device 30 includes a plurality of support seats 31 arranged at intervals and used to contact the product to be measured. In this way, the product to be measured is placed on the plurality of support seats 31, reducing the contact area and reducing the probability of scratches.

[0028] The support seat 31 comprises a first support seat 311 located at the center position and a second support seat 312 surrounding the first support seat 311, both of which can be used to achieve the functions of support and bearing. The first support seat 311 is also used to cooperate with the measurement assembly 20 to realize zeroing and calibration for the measurement device.

[0029] The measurement device 100 has a first state in which at least part of the support seat is adjusted to the inner position, and the support device 30 is a central symmetric structure. In combination Figure 5 As shown, in the first state, a plurality of second support seats 312 are located at the innermost position that can be adjusted, and the second support seats 312 at the diagonal position are centrally symmetric about the first support seat 311, so that the product to be tested is stably and uniformly supported, which is beneficial to the accuracy of the test structure.

[0030] In one embodiment, at least part of the support seat 31 is provided with a support protrusion 33 for contacting the product to be tested, the support protrusion 33 is arranged on the side of the support seat 31 away from the loading platform 10, and the support protrusion 33 has a smooth arc surface with small friction and is not easy to scratch.

[0031] The side of the second support seat 312 away from the loading platform is provided with a support protrusion 33, and the side of the first support seat 311 away from the loading platform 10 is provided with a boss 34, both of which can be used to support the product to be tested.

[0032] In one embodiment, the position of the support seat 31 relative to the loading platform 10 is adjustably arranged, and the positions of the first support seat 311 and the second support seat 312 relative to the loading platform 10 are both adjustably arranged. The second support seat 312 is adjustable to adapt to different sizes and shapes of glass, and the first support seat 311 is adjustable to cooperate with the alignment of the measurement assembly 20.

[0033] In combination Figures 3-4 As shown, the support seat 31 comprises a base 32 arranged on the loading platform 10, the support protrusion 33 is arranged on the side of the base 32 away from the loading platform 10, and the support protrusion 33 is detachably connected with the base 32, which can be used to replace the support protrusion 33 to adapt to different sizes of the product to be tested and the support requirements of different products to be tested.

[0034] The side of the base 32 away from the loading platform 10 is provided with a fixing table 321, the fixing table is provided with a first connecting structure, the side of the support protrusion 33 facing the base 32 is provided with a second connecting structure, the first connecting structure and the second connecting structure are detachably connected and matched, and the first connecting structure and the second connecting structure can be studs and screw holes.

[0035] The base 32 is connected to the object platform 10 by a rotating shaft, and the base 32 rotates around the rotating shaft to drive the supporting protrusions 33 to rotate around the rotating shaft.

[0036] In the embodiment, the base 32 is provided with a fixed table 321 near one end of the first supporting seat 311 for connecting the supporting protrusions 33, and the base 32 is provided with a rotating shaft at the other end away from the first supporting seat 311. In other embodiments, the fixed table 321 and the rotating shaft can also be arranged at other positions of the base 32 according to requirements.

[0037] The base 32 or the supporting protrusions 33 of the second supporting seat 312 are operated to drive the second supporting seat 312 to rotate outwardly. In the first state, the second supporting seat 312 is adjusted to the innermost position, and the supporting device 30 is a central symmetric structure. In the second state, the second supporting seat 312 is adjusted to the outermost position, and the supporting device 30 is a central symmetric structure.

[0038] It can be understood that as long as the second supporting seats 312 ensure the same angle of outward rotation, the supporting device 30 is still a central symmetric structure.

[0039] The base 32 comprises a guide groove 320, the measuring device 100 comprises a guide shaft arranged in the guide groove 320, and the guide shaft is connected to the object platform 10. In specific applications, the guide groove 320 is located between the fixed table 321 and the rotating shaft. It can be understood that if the guide groove 320 and the guide shaft are not arranged, the second supporting seats 312 can rotate 360° around the rotating shaft, and it is impossible to accurately know how many degrees the second supporting seats 312 rotate, and it is impossible to ensure that the second supporting seats 312 simultaneously rotate the same angle, which may cause the position deviation of the supporting protrusions 33, the unevenness of the supporting force provided, and the influence on the accuracy of measurement.

[0040] In this way, the guide groove 320 with a certain range of arc is arranged, and the outward and inward rotation of the second supporting seats 312 is limited, so that the measuring device 100 has a first state in which the second supporting seats 312 simultaneously rotate to the common innermost position, or a second state in which the second supporting seats 312 simultaneously rotate to the common outermost position. Of course, in other embodiments, if the uniformity of the supporting force provided is not high, the second supporting seats 312 can also be arbitrarily rotated to different positions as long as the measured objects can be carried.

[0041] The corresponding range of arc of the guide groove 320 is less than 90°, which can meet the carrying requirements of the measured products, and will not occupy too much space due to the too large required rotation range.

[0042] The first support 311 can be adjusted along a horizontal straight line to accommodate the position of the measuring head 21. The measuring assembly 20 includes a first adjusting device and a second adjusting device connected to the first support 311. The first adjusting device is used to adjust the displacement of the first support 311 along a first direction, and the second adjusting device is used to adjust the displacement of the first support 311 along a second direction. The first and second directions are horizontal and perpendicular to each other.

[0043] In one embodiment, the measuring head 21 corresponds to the center position of the support device 30, and the first support base 311 includes a boss 34 that cooperates with the measuring head 21. Before measurement, the measuring head 21 can abut against the boss 34. On the one hand, the test value of the measuring device 100 is in a zero state; on the other hand, the contact force between the measuring head 21 and the boss 34 is calibrated, and the same contact force needs to be maintained in subsequent measurements.

[0044] Next, the product to be tested can be placed on the support protrusion 33 and the boss 34. During measurement, the measuring head 21 will contact the product to be tested once to obtain one data. If it is necessary to measure different parts of the product to be tested, the product to be tested can also be moved manually. The operating space is large, and the support protrusion 33 is a smooth arc protrusion with low friction, which reduces scratches.

[0045] The measuring component 20 also includes a drive component 23 connected to the measuring head 21 and a foot switch connected to the drive component 23. The foot switch can trigger the drive component 23 to operate, causing the measuring head 21 to move vertically relative to the product being measured. This facilitates operation, frees up both hands, and allows for more complex actions.

[0046] The beneficial effects of this utility model are as follows: the product to be tested is placed on several support seats 31, which reduces the contact area and reduces the probability of scratches; the second support seat 312 is adjustable to adapt to products of different sizes and shapes; the first support seat 311 is adjustable to cooperate with the alignment of the measuring component 20 and improve the accuracy of the measurement.

[0047] This can be formed by referring to any of the technical solutions provided above, and will not be elaborated here.

[0048] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
