Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1

[0027] A preferred embodiment of the multifunctional testing platform for determining cosmetic indicators provided by this utility model is as follows: Figure 1-5 As shown: A multifunctional testing platform for determining cosmetic indicators includes a testing platform 111, a friction gauge digital display panel 112, a friction gauge connection accessory 114, and a multifunctional converter assembly 3. A local 3D simulated skin model placement device 113 is provided on the top of the testing platform 111, and an adjustable lifting device 2 is also provided on the top of the testing platform 111. The adjustable lifting device 2 is electrically connected to the multifunctional converter assembly 3 through the friction gauge connection accessory 114.

[0028] The adjustable lifting device 2 specifically includes the following structure: a base 211, which is fixedly installed on the top of the measuring table 111; and a curved column 212, which is fixedly installed on the top of the base 211.

[0029] The front of the curved column 212 is fixedly mounted to the friction gauge digital display panel 112. Adjustment grooves are provided on both sides of the curved column 212, and a retaining shaft 217 is movably installed through the middle of the adjustment groove. Retaining gears 216 are fixedly connected to both ends of the retaining shaft 217. Retaining holes are equidistantly provided on the outer circumference of the retaining shaft 217, and a stop shaft 227 is appropriately fitted on the retaining holes.

[0030] The inside of the adjusting groove is fitted with a toothed frame plate 214, and the top of the toothed frame plate 214 penetrates the top of the inner wall of the adjusting groove and extends upward. A round hole plate 215 is integrally connected to the top of the toothed frame plate 214, and one side of the inner wall of the toothed frame plate 214 is meshed with a locking gear 216.

[0031] A side panel 213 is fixedly installed on the outside of the adjustment groove. A locking box 221 is fixedly installed on the outer wall of the side panel 213. An elastic clip 222 is fixedly installed in the middle of the inside of the locking box 221. A button block 223 is fixedly connected to the pins at both ends of the elastic clip 222. A pin post 224 contacts one of the pins of the elastic clip 222.

[0032] The outer wall of the ejector pin 224 is integrally connected with a stop protrusion 225. The top of the ejector pin 224 penetrates the top of the inner wall of the locking box 221 and extends to the outside to engage with the inner hole on the stop shaft 227. A compression spring 226 is sleeved on the outer wall of the ejector pin 224. One end of the compression spring 226 is fixedly connected to the top of the inner wall of the locking box 221, and the other end of the compression spring 226 is fixedly connected to the top of the stop protrusion 225.

[0033] A connecting bracket 228 is fixedly connected to the circular hole plate 215, and is fixedly set to the multi-functional converter assembly 3 through the connecting bracket 228;

[0034] In this embodiment, the friction meter digital display panel 112, the friction meter connection accessory 114, and the multi-functional converter assembly 3 are combined to form a precision digital friction meter, which can directly read the friction force value to reflect the composite index. The local 3D simulated skin model placer 113 is used to place the local 3D simulated skin model and provides a corresponding structure for measuring the composite index. By setting the adjustable lifting device 2, an operable device is provided for the precision digital friction meter and the local 3D simulated skin model.

[0035] In this embodiment, due to the mutual compression of the button blocks 223, and the fact that the elastic clip 222 is made of an elastic, easily deformable, and recoverable material, the button blocks 223, when moving, cause the elastic clip 222 to undergo elastic deformation. This deformation causes the ejector pin 224 on the elastic clip 222 to move downwards under the elastic action of the compression spring 226, thereby disengaging the ejector pin 224 from its engagement with the inner hole on the stop shaft 227. At this point, simply pulling out the stop shaft 227 disengages it from the locking hole, thus releasing the locked state of the locking shaft 217.

[0036] Next, by adjusting the toothed frame plate 214 up and down, the toothed frame plate 214 can be raised and lowered under the action of the locking gear 216. In this way, the multi-functional converter assembly 3 can be raised and lowered, thereby achieving the effect of height adjustment. Throughout the process, the material and structural design of the elastic clamp 222 enable it to deform when subjected to external force, but to return to its original shape after the external force is removed, which ensures the normal operation of the entire mechanism.

[0037] Example 2

[0038] Please see Figures 1-5 Furthermore, based on Embodiment 1, the following structure is obtained: the multi-functional converter assembly 3 specifically includes the following structure: a converter housing 311, which is fixedly mounted on a circular hole plate 215 via a connecting bracket 228; a rotary motor is provided inside the converter housing 311, and the output shaft of the rotary motor is fixedly connected to a conversion disk 312, which is located at the bottom of the converter housing 311; three sets of conversion heads 313 and a matching replaceable rotary head 314 are fixedly mounted circumferentially on the bottom surface of the conversion disk 312; a snap-fit ​​slot block 315 is fixedly mounted circumferentially on the end of the conversion head 313; and a snap-fit ​​protrusion 316 is fixedly mounted circumferentially on the end of the replaceable rotary head 314, wherein the snap-fit ​​protrusion 316 is engaged with the snap-fit ​​slot block 315.

[0039] In this embodiment, by setting up a multi-functional converter assembly 3, when the rotary motor is started, the rotary motor drives the conversion disk 312 to rotate, and the conversion disk 312 drives the three sets of conversion heads 313 and the corresponding replaceable rotary heads 314 to rotate. By changing the conversion heads 313 of different multi-functional converters, the conversion heads 313 rotate at a certain speed on the contact area 3D skin model, thereby obtaining certain data, and feeding the data back to the friction meter digital display disk 112, thereby judging the composite index. The rolling friction force when it is first applied, the time required to reach a certain friction force, and the friction force after a certain time are measured to read the corresponding values. The three index parameters of spreadability, absorption and slipperiness can be obtained respectively, providing a reference for subsequent evaluation.

[0040] In this specific embodiment, an innovative design is adopted, namely, a series of snap-fit ​​slots 315 are fixedly installed at equal intervals on the end circumference of the adapter head 313. These snap-fit ​​slots 315 are ingeniously designed; they not only match the snap-fit ​​protrusions 316 fixed at equal intervals on the end circumference of the replaceable rotary head 314, but also provide a stable connection when the rotary head 314 is combined with the adapter head 313. This structure allows the snap-fit ​​protrusions 316 to easily engage with the snap-fit ​​slots 315, thereby enabling the rotary head 314 to be easily installed onto or removed from the adapter head 313. This design greatly simplifies the replacement process of the replaceable rotary head, improves work efficiency, and reduces the risk of malfunctions during replacement. In summary, this design not only enables rapid disassembly and replacement of the replaceable rotary head 314, but also ensures the stability and reliability of the connection, greatly improving the ease of maintenance and use of the equipment.

[0041] In use, the sampled local 3D simulated skin model to be tested is placed on the local 3D simulated skin model placer 113. By pressing the button block 223 against each other, the elastic clip 222, which is made of a material that is elastic, easily deformable and recoverable, causes the button block 223 to drive the elastic clip 222 to undergo elastic deformation. This causes the ejector pin 224 on the pin of the elastic clip 222 to move downward under the action of the compression spring 226 to recover its elasticity. This causes the ejector pin 224 to disengage from the inner hole on the stop shaft 227. At this time, the stop shaft 227 is pulled out, causing the stop shaft 227 to disengage from the locking hole. The locking state of the locking shaft 217 is then released. Then, by adjusting the toothed frame plate 214 up and down, the toothed frame plate 214 can be raised and lowered under the action of the locking gear 216, thereby driving the multi-functional converter assembly 3 to be raised and lowered.

[0042] At this time, after the rotary motor is started, the rotary motor drives the conversion disk 312 to rotate. The conversion disk 312 drives the three sets of conversion heads 313 and the corresponding replaceable rotary heads 314 to rotate. The conversion heads 313 rotate at a certain speed on the contact area 3D skin model, thereby obtaining certain data and feeding the data back to the friction meter digital display disk 112, and then judging the composite index. The rolling friction force when it is first applied, the time required to reach a certain friction force, and the friction force after a certain time are measured to read the corresponding values. The three index parameters of spreadability, absorption and slipperiness can be obtained respectively, providing a reference for subsequent evaluation.

[0043] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships.

Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

[0045] Finally, the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
