Abstract
Description
Technical Field
[0001] This invention belongs to the field of lipstick technology, specifically a testing device for lipstick. Background Technology
[0002] Lipstick is a cosmetic used for lip care and decoration. It has functions such as preventing dry and chapped lips, changing lip color, improving complexion, and protecting against UV damage. Common types include lip balm, tinted lipstick, lipstick, and lip gloss / lip stain.
[0003] A search revealed a lipstick breakage testing device with authorization announcement number CN216594473U. This device addresses the issue that existing tests only assess the hardness of lipsticks, failing to measure their folding and abrasion resistance in practical applications. It utilizes a drive assembly, a lipstick holder, a force adjustment assembly, and a simulator. The lipstick holder moves under the drive of a straight rod, causing the lipstick on it to reciprocate onto the simulator. This simulates the motion of a person wiping a lipstick, offering the advantage of testing lipstick abrasion resistance by observing the degree of breakage and wear. However, it has shortcomings in practical use. Since there is only one lipstick holder and one simulator, testing can only be performed individually. Furthermore, the single simulator requires operators to clean and replace it before each test, reducing testing efficiency. Therefore, improvements are needed. Summary of the Invention
[0004] The purpose of this invention is to address the above-mentioned problems. This invention provides a testing device for lipsticks, which has the advantage of not requiring frequent replacement of the simulant.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a testing device for lipstick, comprising a workbench, a mounting box fixedly installed on the left side of the top of the workbench, a fixing plate fixedly installed on the right side of the top of the workbench, a circular shaft movably sleeved inside the fixing plate, a turntable fixedly sleeved on the left side of the outer surface of the circular shaft, the right end of the turntable movably connected to the left end of the fixing plate, and a simulation body fixedly installed on the left end of the turntable. The number of simulation bodies is four, and they are symmetrical about the center of the circular shaft. A gear is fixedly sleeved on the right side of the plate. The left end of the gear is movably connected to the right end of the fixed plate. A toothed plate is movably connected to the bottom of the outer surface of the gear. The left end of the toothed plate is movably connected to the right end of the fixed plate. A fixed frame is movably sleeved on the outer surface of the toothed plate. The left end of the fixed frame is fixedly connected to the right end of the fixed plate. A threaded rod is threaded into the internal thread of the toothed plate. The front and rear ends of the threaded rod pass through the fixed frame and extend to the outside of the fixed frame, and a handle is fixedly sleeved on them. The outer surface of the handle is movably connected to the outer surface of the fixed frame.
[0006] As a preferred embodiment of this invention, the outer surface of the turntable is provided with a positioning hole located beside the simulation body, and a positioning rod located at the top of the simulation body is movably sleeved inside the positioning hole.
[0007] As a preferred embodiment of this utility model, a fixed frame is movably sleeved on the top of the outer surface of the positioning rod, the right side of the bottom end of the fixed frame is fixedly connected to the top of the fixed plate, an extension plate is movably sleeved on the bottom of the inside of the fixed frame, and the inner surface of the left end of the extension plate is fixedly sleeved on the outer surface of the positioning rod.
[0008] As a preferred embodiment of this utility model, a limiting rod is movably sleeved inside the right end of the extension plate, and the upper and lower ends of the limiting rod are respectively fixedly connected to the upper and lower inner walls of the fixed frame. A spring located outside the limiting rod is fixedly installed at the top of the extension plate, and the other end of the spring is fixedly connected to the top of the inner surface of the fixed frame.
[0009] As a preferred embodiment of this utility model, a force display is fixedly installed on the rear side of the top center of the mounting box, and a force control button is movably installed on the front side of the top center of the mounting box.
[0010] As a preferred embodiment of this invention, a drive assembly is fixedly sleeved inside the mounting box, and a straight rod is movably mounted on the right end of the drive assembly.
[0011] As a preferred embodiment of this utility model, a fixing sleeve is fixedly installed at the right end of the straight rod, and a tension adjustment rod is threadedly connected to the middle of the top end of the fixing sleeve.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] This invention incorporates a circular shaft, a turntable, a gear, a toothed plate, and a threaded rod. When the handle is turned, the threaded rod rotates. Since the outer surface of the threaded rod is threadedly engaged with the inner surface of the toothed plate, the toothed plate moves along the inner surface of the fixed frame as the threaded rod rotates. This causes the gear, which meshes with the toothed plate, to rotate the turntable and the simulation object via the circular shaft. This allows for the switching of the simulation object, improving the ease of use of the testing device and eliminating the need for operators to frequently change simulation objects.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] like Figures 1 to 5As shown, this utility model provides a testing device for lipstick, including a workbench 1. A mounting box 2 is fixedly installed on the left side of the top of the workbench 1, and a fixing plate 3 is fixedly installed on the right side of the top of the workbench 1. A circular shaft 4 is movably sleeved inside the fixing plate 3. A turntable 5 is fixedly sleeved on the left side of the outer surface of the circular shaft 4. The right end of the turntable 5 is movably connected to the left end of the fixing plate 3. A simulation body 6 is fixedly installed on the left end of the turntable 5. There are four simulation bodies 6, which are symmetrical about the circular shaft 4. A gear 7 is fixedly sleeved on the right side of the outer surface of the circular shaft 4. The left end of the gear 7 is movably connected to the right end of the fixing plate 3. A toothed plate 8 is movably connected to the bottom of the outer surface of the gear 7. The left end of the toothed plate 8 is movably connected to the right end of the fixing plate 3. A fixing frame 9 is movably sleeved on the outer surface of the toothed plate 8. The left end of the fixing frame 9 is fixedly connected to the right end of the fixing plate 3. The toothed plate 8 has internal threads. A threaded rod 10 is fitted onto the device. The front and rear ends of the threaded rod 10 pass through the fixed frame 9 and extend to the outside of the fixed frame 9, and a handle 11 is fixedly fitted onto it. The outer surface of the handle 11 is movably connected to the outer surface of the fixed frame 9. When the handle 11 is rotated, the threaded rod 10 will rotate along the inner surface of the fixed frame 9. Since the threaded rod 10 and the toothed plate 8 are threadedly fitted, the toothed plate 8 will move along the inner surface of the fixed frame 9 as the threaded rod 10 rotates. Since the outer surface of the gear 7 and the top of the toothed plate 8 mesh with each other, the gear 7 will rotate along with the turntable 5 through the round shaft 4 as the toothed plate 8 moves. The left end of the turntable 5 is provided with four simulation bodies 6. Therefore, the simulation body 6 can be switched every time the turntable 5 rotates 90 degrees, so that the operator does not need to frequently change the simulation body 6, thereby improving the convenience of using the testing device.
[0022] The turntable 5 has a positioning hole 12 on its outer surface located next to the simulation body 6. The positioning hole 12 is movably fitted with a positioning rod 13 located on the top of the simulation body 6. There are four positioning holes 12, and they correspond to the positions of the four simulation bodies 6. Through the cooperation of the positioning holes 12 and the positioning rods 13, the position of the simulation body 6 will be positioned, thereby ensuring that the position of the simulation body 6 after switching will not be offset and affect the test.
[0023] The top of the outer surface of the positioning rod 13 is movably sleeved with a fixed frame 14. The right side of the bottom end of the fixed frame 14 is fixedly connected to the top of the fixed plate 3. The bottom of the fixed frame 14 is movably sleeved with an extension plate 15. The inner surface of the left end of the extension plate 15 is fixedly sleeved with the outer surface of the positioning rod 13. When the extension plate 15 is moved, it will move along the inner surface of the fixed frame 14, thereby causing the positioning rod 13, which is fixedly sleeved with the extension plate 15, to move together and separate from the positioning hole 12, thus releasing the locking of the positioning rod 13 to the rotation position of the turntable 5.
[0024] The extension plate 15 has a limit rod 16 movably sleeved inside its right end. The upper and lower ends of the limit rod 16 are fixedly connected to the upper and lower inner walls of the fixed frame 14, respectively. A spring 17 located outside the limit rod 16 is fixedly installed at the top of the extension plate 15. The other end of the spring 17 is fixedly connected to the top of the inner surface of the fixed frame 14. When the extension plate 15 is moved along the inner surface of the fixed frame 14, the spring 17 will be compressed by the extension plate 15. Under the restoring action of the spring 17, the extension plate 15 will be forced to return to its original position with the positioning rod 13. At the same time, the presence of the limit rod 16 will limit the extension plate 15.
[0025] The mounting box 2 has a force display 18 fixedly installed on the rear side of the top center and a force control button 19 movably installed on the front side of the top center. The force display 18 and the force control button 19 are used to control the contact force between the lipstick and the simulation body 6. Through the cooperation of the force display 18 and the force control button 19, the action of applying lipstick to the human body can be simulated more accurately.
[0026] The installation box 2 has a drive assembly 20 fixedly connected inside, and a straight rod 21 is movably installed on the right end of the drive assembly 20. The presence of the drive assembly 20 is used to control the movement of the straight rod 21, so as to facilitate the simulation of the human body lifting the lipstick to wipe it, thereby realizing the test of the lipstick's abrasion resistance.
[0027] The right end of the straight rod 21 is fixedly fitted with a fixing sleeve 22, and the middle of the top of the fixing sleeve 22 is threaded with a tension adjustment rod 23. Since the outer surface of the tension adjustment rod 23 is threaded with the inner surface of the top of the fixing sleeve 22, when the tension adjustment rod 23 is rotated, the tension adjustment rod 23 can move towards the inside of the fixing sleeve 22, thereby fixing the lipstick inside the fixing sleeve 22.
[0028] Working principle and usage process of this utility model:
[0029] Before testing, if it is necessary to switch the simulator 6, the operator first moves the extension plate 15, causing the extension plate 15 to move along the inner surface of the fixed frame 14 with the positioning rod 13 and compress the spring 17, thereby separating the positioning rod 13 from the positioning hole 12 and releasing the locking of the positioning rod 13 to the rotation position of the turntable 5. Then, the operator turns the handle 11, causing the threaded rod 10 to rotate, thereby causing the toothed plate 8, which is threadedly connected to the threaded rod 10, to move along the inner surface of the fixed frame 9. In turn, the gear 7, under the action of the toothed plate 8, rotates the turntable 5 and the simulator 6 through the round shaft 4. When the turntable 5 rotates 90 degrees, the simulator 6 can be switched, thus eliminating the need for the operator to frequently change the simulator 6, thereby improving the convenience of using the testing device.
[0030] When the turntable 5 rotates and the positioning rod 13 and the initial positioning hole 12 are misaligned, the operator can release the extension plate 15. At this time, under the restoring action of the spring 17, the positioning rod 13 and the outer surface of the turntable 5 will remain in contact. When the turntable 5 rotates ninety degrees, the positioning hole 12 at another position will align with the positioning rod 13. At this time, the positioning rod 13 will continue to move under the restoring action of the spring 17 and embed into the corresponding positioning hole 12. This can achieve the positioning of the rotation position of the turntable 5, thereby preventing the simulation body 6 from rotating excessively and causing positional deviation.
