DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

[0026] Example 1

[0027] A preferred embodiment of the cosmetic sensory evaluation composite index measuring instrument provided by the present invention is as follows: Figure 1-5 As shown: a cosmetic sensory evaluation composite index measuring instrument, comprising a measuring platform 111, a friction meter digital display panel 112, a friction meter connecting accessory 114 and a multifunctional converter assembly 3, a local 3D simulation skin model placing device 113 is arranged on the top of the measuring platform 111, an adjustable lifting device 2 is also arranged on the top of the measuring platform 111, and the adjustable lifting device 2 is electrically connected to the multifunctional converter assembly 3 through the friction meter connecting accessory 114;

[0028] The adjustable lifting device 2 specifically includes the following structures: a base 211, fixedly mounted on the top of the measuring platform 111; a curved column 212, fixedly mounted on the top of the base 211;

[0029] The front of the curved column 212 is fixedly arranged with the friction meter digital display plate 112, and adjustment grooves are provided on both sides of the curved column 212, and a clamping shaft 217 is movably provided at the middle position of the adjustment groove, and the two ends of the clamping shaft 217 are fixedly connected with a clamping gear 216, and the outer wall circumference of the clamping shaft 217 is provided with clamping holes at equal intervals, and a stop shaft 227 is adapted to be provided on the clamping hole;

[0030] The inside of the adjustment groove is adapted to be equipped with a tooth frame plate 214, and the top of the tooth frame plate 214 passes through the top of the inner wall of the adjustment groove and extends upward, and a circular hole plate 215 is integrally connected to the top of the tooth frame plate 214, and one side of the inner wall of the tooth frame plate 214 is meshed and connected with a card gear 216;

[0031] A side panel 213 is fixedly installed on the outer side of the adjustment slot, a locking box 221 is fixedly installed on the outer wall of the side panel 213, an elastic clip 222 is fixedly arranged at the middle position inside the locking box 221, button blocks 223 are fixedly connected to the pins at both ends of the elastic clip 222, and a pin of one of the elastic clips 222 contacts an ejector pin 224;

[0032] The outer wall of the ejector column 224 is integrally connected with a stop convex body 225, the top of the ejector column 224 passes through the top of the inner wall of the locking box 221 and extends to the outside to engage with the inner hole of the stop shaft 227, and the outer wall of the ejector column 224 is sleeved with a compression spring 226, 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 convex body 225;

[0033] The circular hole plate 215 is fixedly connected with a connecting bracket 228, and is fixedly arranged with the multifunctional converter assembly 3 through the connecting bracket 228;

[0034] In this embodiment, the friction meter digital display disk 112, the friction meter connecting accessories 114 and the multi-functional converter assembly 3 are combined to form a precision digital friction meter, which can directly read the friction value to reflect the composite index. Among them, the local 3D simulated skin model placer 113 is used to place the local 3D simulated skin model to provide a corresponding structure for measuring the composite index. By setting an 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, the button blocks 223 are pressed against each other, and since the elastic clip 222 is made of a material that is elastic, easy to deform and recoverable, when the button block 223 moves, it drives the elastic clip 222 to deform elastically. This deformation causes the ejector pin 224 on the elastic clip 222 to move downward under the elastic action of the compression spring 226, thereby causing the ejector pin 224 to break away from the state of being engaged with the inner hole of the stop shaft 227. At this time, the stop shaft 227 can be separated from the locking hole by simply pulling out the stop shaft 227, thereby releasing the locked state of the locking shaft 217.

[0036] Next, by adjusting the tooth frame plate 214 up and down, the tooth frame plate 214 can be raised and lowered under the action of the card gear 216. In this way, the multifunctional converter assembly 3 can be driven to be raised and lowered, thereby achieving the effect of lifting and lowering adjustment. In the whole process, the material and structural design of the elastic clip 222 enable it to deform when subjected to external force, but can return to its original state after the external force is removed, which provides a guarantee for the normal operation of the entire mechanism.

[0037] Example 2

[0038] See also Figure 1-Figure 5 , and on the basis of Example 1, it is further obtained that the multifunctional converter assembly 3 specifically includes the following structure: a converter housing 311, which is fixedly installed on the circular hole plate 215 through a connecting bracket 228; a rotating motor is arranged inside the converter housing 311, and a conversion disk 312 is fixedly connected to the output shaft of the rotating motor, and the conversion disk 312 is located at the bottom of the converter housing 311, and three groups of conversion heads 313 and a corresponding replaceable rotating head 314 are fixedly installed at equal intervals on the bottom surface of the conversion disk 312, and buckle groove blocks 315 are fixedly installed at equal intervals on the end of the conversion head 313, and buckle cams 316 are fixedly installed at equal intervals on the end of the replaceable rotating head 314, wherein the buckle cams 316 are snap-fitted and connected with the buckle groove blocks 315.

[0039] In this embodiment, by setting a multifunctional converter assembly 3, when the rotating motor is started, the rotating motor drives the conversion disk 312 to rotate, and the conversion disk 312 drives three groups of conversion heads 313 and a corresponding replaceable rotating head 314 to rotate. The conversion head 313 of different multifunctional converters is replaced, and the conversion head 313 rotates at a certain speed on the contact local 3D skin model to obtain certain data, and then feeds the data back to the friction meter digital display disk 112, and then judges the composite index, respectively measures the rolling friction force when just applied, the time required to reach a certain friction force, and the friction force after a certain time, so as to read the corresponding values, and respectively obtain the three index parameters of spreadability, absorbency and slipperiness, which provide a reference for subsequent evaluation.

[0040] In this specific embodiment, an innovative design scheme is adopted, that is, a series of snap groove blocks 315 are fixedly installed at equal intervals on the end circumference of the conversion head 313. The design of these snap groove blocks 315 is ingenious. They can not only match the snap convex falcons 316 fixed at equal intervals on the end circumference of the replaceable rotating head 314, but also provide a stable connection when the rotating head 314 is combined with the conversion head 313. This structure allows the snap convex falcons 316 to be easily snapped together with the snap groove blocks 315, so that the rotating head 314 can be easily installed on the conversion head 313, or removed from the conversion head 313. This design greatly simplifies the replacement process of the replaceable rotating head, improves work efficiency, and also reduces the risk of failure that may occur during the replacement process. In general, this design not only realizes the rapid disassembly and replacement of the replaceable rotating head 314, but also ensures the stability and reliability of the connection, greatly improving the maintenance and convenience of the equipment.

[0041] When in use, the local 3D simulated skin model to be tested with the sample added is placed on the local 3D simulated skin model placement device 113, and the button blocks 223 are squeezed against each other. Since the elastic clip 222 is made of a material that is elastic, easy to deform and recoverable, the button block 223 drives the elastic clip 222 to undergo elastic deformation, prompting the ejector column 224 on the pin of the elastic clip 222 to move downward under the action of the compression spring 226 wanting to recover its elasticity, so that the ejector column 224 is disengaged from the engagement state with the inner hole on the stop shaft 227. At this time, the stop shaft 227 is pulled out again, so that the stop shaft 227 is disengaged from the clamping hole, and the locking state of the clamping shaft 217 is released at this time, and then the tooth frame plate 214 is adjusted up and down, and the tooth frame plate 214 can be lifted up and down under the action of the clamping gear 216, thereby driving the multi-functional converter assembly 3 to be lifted up and down;

[0042] At this time, after starting the rotating motor, the rotating motor drives the conversion disk 312 to rotate, and the conversion disk 312 drives three sets of conversion heads 313 and the corresponding replaceable rotating head 314 to rotate. The conversion head 313 rotates at a certain speed on the contact local 3D skin model, and then obtains certain data, and feeds the data back to the friction meter digital display disk 112, and then judges the composite index, respectively measures the rolling friction force when just applied, the time required to reach a certain friction force, and the friction force after a certain time, so as to read the corresponding values, and obtain the three index parameters of spreadability, absorbency and slipperiness, respectively, to provide a reference for subsequent evaluation.
