[0040] In order to further understand the application content, features and effects of the present application, the following embodiments are cited and described in detail with reference to the accompanying drawings.

[0041] Embodiment 1

[0042] See also Figure 1 and Figure 2 , Figure 1 This is a three-dimensional diagram of the lipstick packaging structure. Figure 2 This is an exploded view of the lipstick packaging structure. The lipstick packaging structure in this example includes an outer shell 1, an inner tube 2, a transmission mechanism 3, a first mounting platform 4 and a second mounting platform 5. The outer shell 1 is used to protect the lipstick in the inner tube 2 from external pollution and drive the transmission mechanism 3. The inner tube 2 is used to carry the first mounting platform 4 and the second mounting platform 5. The first mounting platform 4 is used to carry one type of lipstick, and the first mounting platform 4 is used to carry another type of lipstick. The transmission mechanism 3 is used to drive the first mounting platform 4 and the second mounting platform 5 to rise or fall along the inner tube 2.

[0043] Please also read Figure 3 and Figure 4 , Figure 3 This is a cross-sectional view of the lipstick packaging structure. Figure 4 for Figure 3 The enlarged view of the area a in the middle shows that the transmission mechanism 3 is arranged at the bottom of the inner tube 2, and the outer shell 1 includes an upper shell 11 and a lower shell 12. The upper shell 11 is covered on the upper end of the inner tube 2 and is detachably connected to the inner tube 2. The lower shell 12 is covered on the lower end of the inner tube 2 and is rotatably connected to the inner tube 2. The lower shell 12 is also connected to the transmission mechanism 3 in a transmission manner. The first mounting platform 4 and the second mounting platform 5 are both connected to the transmission mechanism 3. The first mounting platform 4 and the second mounting platform 5 are both arranged in the inner tube 2. The first mounting platform 4 and the second mounting platform 5 slide up and down along the length direction of the inner tube 2 and are respectively connected to the transmission mechanism 3. When the lower shell 12 is rotated to rotate relative to the positive direction of the inner tube 2, the distance between the first mounting platform 4 and the lower shell 12 gradually increases. In addition, the distance between the second mounting platform 5 and the lower shell 12 remains unchanged or gradually decreases; when the lower shell 12 is rotated to make the lower shell 12 rotate in the opposite direction relative to the inner tube 2, the distance between the second mounting platform 5 and the lower shell 12 gradually increases, and the distance between the first mounting platform 4 and the lower shell 12 remains unchanged or gradually decreases; it should be noted that when the lower shell 12 is rotated to make the lower shell 12 rotate in the positive direction relative to the inner tube 2, the distance between the first mounting platform 4 and the lower shell 12 gradually increases, and the distance between the second mounting platform 5 and the lower shell 12 gradually decreases, and when the reverse rotation is performed, the distance between the first mounting platform 4 and the lower shell 12 gradually decreases, the initial positions of the first mounting platform 4 and the second mounting platform 5 should both be located at the midpoint of the length direction of the inner tube 2.

[0044] In specific application, the lipstick packaging structure is loaded with lipstick, which can be loaded with two different color lipsticks or two different types of lipsticks. The two lipsticks are respectively mounted on the first mounting platform 4 and the second mounting platform 5. When the user needs to use the lipstick, the upper shell 11 needs to be removed from the inner tube 2 to expose the upper end of the inner tube 2. When the lipstick located on the first mounting platform 4 needs to be used, the user needs to rotate the lower shell 12 in the positive direction so that the lower shell 12 rotates relative to the positive direction of the inner tube. The lower shell 12 drives the transmission mechanism 3 to rotate, and the transmission mechanism 3 drives the first mounting platform 4 to move in the direction away from the lower shell 12, that is, the transmission mechanism 3 drives the first mounting platform 4 to move in the direction away from the lower shell 12. The lipstick on the first mounting platform 4 is moved toward the upper end of the inner tube 2 until the lipstick on the first mounting platform 4 is exposed to the upper end of the inner tube 2, and the user can use the lipstick on the first mounting platform 4; when the lipstick on the second mounting platform 5 needs to be used, the user needs to rotate the lower shell 12 in the opposite direction to make the lower shell 12 rotate in the opposite direction relative to the inner tube, and the lower shell 12 drives the transmission mechanism 3 to rotate, and the transmission mechanism 3 drives the second mounting platform 5 to move in the direction away from the lower shell 12, that is, the transmission mechanism 3 drives the second mounting platform 5 to move toward the upper end of the inner tube 2 until the lipstick on the second mounting platform 5 is exposed to the upper end of the inner tube 2, and the user can use the lipstick on the second mounting platform 5.

[0045] In this way, by setting the first mounting platform 4 and the second mounting platform 5 to respectively mount two different lipsticks, and using the transmission mechanism 3 to respectively control the first mounting platform 4 and the second mounting platform 5, the user controls the shell 1 to rotate in the positive direction or the reverse direction to respectively control the first mounting platform 4 to rise or the second mounting platform 5 to rise, thereby achieving a lipstick packaging structure that can accommodate and independently control two different lipsticks.

[0046] Furthermore, the transmission mechanism 3 includes two transmission components 31, and the transmission component 31 includes a first transmission member 311 and a second transmission member 312. The first transmission member 311 is transmission-connected to the lower shell 12, and the second transmission member 312 is unidirectionally limitedly connected to the first transmission member 311. The two transmission components 31 are symmetrically arranged along the axis of the lower shell 12, and the first mounting platform 4 and the second mounting platform 5 are respectively installed on the two second transmission members 312.

[0047] Specifically, the first mounting platform 4 and the second mounting platform 5 are respectively installed on the two transmission components 31, and the two first transmission members 311 are both transmission-connected with the housing 1. The second transmission member 312 of one transmission component 31 is engaged with the first transmission member 311 when rotating in the positive direction, and is rotationally connected when rotating in the reverse direction. The second transmission member 312 of the other transmission component 31 is engaged with the first transmission member 311 when rotating in the reverse direction, and is rotationally connected when rotating in the positive direction. That is, the second transmission members 312 of the two transmission components 31 are in opposite directions to the one-way limiting connection directions of the first transmission member 311.

[0048] In this way, when the lower shell 12 is rotated so that the lower shell 12 rotates in the positive direction relative to the inner tube 2, the distance between the first mounting platform 4 and the lower shell 12 gradually increases, and the distance between the second mounting platform 5 and the lower shell 12 remains unchanged; when the lower shell 12 is rotated so that the lower shell 12 rotates in the reverse direction relative to the inner tube 2, the distance between the second mounting platform 5 and the lower shell 12 gradually increases, and the distance between the first mounting platform 4 and the lower shell 12 remains unchanged, thereby realizing independent control of the first mounting platform 4 and the second mounting platform 5.

[0049] Furthermore, the inner tube 2 includes a tube body 21 and a seat body 22. The seat body 22 is arranged at one end of the tube body 21, and the end thereof facing the tube body 21 has two shaft seats 221. The two shaft seats 221 are symmetrically arranged along the axis of the tube body 21. The lower shell 12 is covered on the end of the tube body 21 where the seat body 22 is provided, and is rotatably connected to the tube body 21. The upper shell 11 is installed at the other end of the tube body 21. The first transmission member 311 is located between the tube body 21 and the seat body 22, and is rotatably connected to the shaft seat 221.

[0050] Please also read Figure 5 , Figure 5It is a schematic diagram of the seat structure, specifically, the seat body 22 is arranged at the lower end of the tube body 21, the lower shell 12 is sleeved on the seat body 22 and the lower end of the tube body 21, the lower shell 12 is rotatably connected to the tube body 21 and the seat body 22 respectively, and the upper shell 11 is installed at the upper end of the tube body 21; the two first transmission members 311 are respectively installed on the two shaft seats 221, the two first transmission members 311 are respectively rotatably connected to the two shaft seats 221, the two first transmission members 311 are respectively transmission connected to the lower shell 12, and the lower shell 12 is rotated, and the lower shell 12 drives the two first transmission members 311 to rotate in the same direction.

[0051] In this way, by disposing the shaft seat 221 on the seat body 22 , the two transmission components 31 are both disposed on the inner tube 2 , thereby ensuring the stability of the transmission between the two transmission components 31 and the lower shell 12 .

[0052] Please also read Figure 6 , Figure 7 and Figure 8 , Figure 6 is a schematic diagram of the structure of the first transmission member, Figure 7 is a cross-sectional view of the second transmission member, Figure 8 for Figure 7 In the enlarged view of the middle b area, further, the transmission assembly 31 also includes an elastic member 313, which is located between the seat body 22 and the first transmission member 311, and respectively abuts against the seat body 22 and the first transmission member 311; the first transmission member 311 has a first boss 3111 at one end facing away from the shaft seat 221, and the second transmission member 312 includes a sleeve 3121 and a screw 3122, the sleeve 3121 is sleeved on the first transmission member 311, one end of which abuts against the first transmission member 311, and the other end abuts against the tube body 21, and the sleeve 3121 has a second boss 31211 and a slide 3122 12, the second boss 31211 is arranged to face the first boss 3111, and the slide 31212 is arranged along the circumferential direction, which is located on one side of the second boss 31211, one side of which smoothly transitions with the wall surface of the sleeve 3121, and the other side smoothly transitions with the table surface of the second boss 31211; the screw rod 3122 is located in the tube body 21 and connected to the sleeve 3121; the slides 31212 of the two transmission assemblies 31 are respectively located on different sides of the second boss 31211, and the thread directions of the two screw rods 3122 are opposite, and the first mounting platform 4 and the second mounting platform 5 are respectively installed on the two screw rods 3122.

[0053] Specifically, the second transmission member 312 is arranged above the first transmission member 311, and the elastic member 313 is located below the first transmission member 311. One end of the elastic member 313 is elastically connected to the base, and the other end is elastically connected to the first elastic member 313. The first transmission member 311 has a first boss 3111 at one end facing away from the elastic member 313, that is, the first transmission member 311 is provided with a first boss 3111 above, and the second transmission member 312 is sleeved on the first transmission member 311 and provided with a The second boss 31211 is clamped with the first boss 3111. When the first transmission member 311 rotates, the first boss 3111 of the first transmission member 311 drives the second boss 31211 of the second transmission member 312 to move synchronously. The shaft sleeve 3121 is also provided with a slide 31212, which is located on one side of the second boss 31211. In the two transmission components 31, the slides 31212 are respectively located on the second boss 31211 and the second boss 31211. On different sides, when the first transmission member 311 rotates, the first boss 3111 can slide from the bottom surface of the shaft seat 221 along the slide 31212 to the bottom surface of the second boss 31211, that is, when the first boss 3111 rotates from the side of the second boss 31211 provided with the slide 31212 toward the side of the second boss 31211 not provided with the slide 31212, the first boss 3111 and the second boss 31211 are not engaged. When the side of 31211 without the slide 31212 rotates toward the side of the second boss 31211 with the slide 31212, the first boss 3111 is engaged with the second boss 31211; when the first boss 3111 is engaged with the second boss 31211, the first transmission member 311 is transmission-connected with the second transmission member 312; when the first boss 3111 is not engaged with the second boss 31211, the first transmission member 311 is rotationally connected with the second transmission member 312.

[0054] In this example, the slopes 31212 of the two transmission components 31 are slope A31213 and slope B31214 respectively. Slope A31213 is located on the clockwise side of the second boss 31211, and slope B31214 is located on the counterclockwise side of the second boss 31211. Slope A31213 and slope B31214 are both inclined surfaces. The distance between the lower surface of the slope 31212 and the first transmission member 311 gradually increases from the end close to the second boss 31211 to the end away from the second boss 31211; the two screws 3122 have threads A3123 and threads B3124 respectively, and threads A3123 and B3124 are forward threads and reverse threads respectively.

[0055] In this example, the first transmission member 311 has a plurality of first bosses 3111, the second transmission member 312 has three second bosses 31211, the number of slides 31212 is the same as the number of second bosses 31211, and correspondingly, the second transmission member 312 has three slides 31212, the three second bosses 31211 are arranged at intervals along the circumferential direction on the side of the sleeve 3121 facing the first transmission member 311, the three first bosses 3111 are arranged at intervals along the circumferential direction on the first transmission member 311, the slopes A31213 are all located on the clockwise side of the second bosses 31211, and the slopes B31214 are located on the counterclockwise side of the second bosses 31211.

[0056] During specific application, the user rotates the lower shell 12, and the lower shell 12 drives the two first transmission members 311 to rotate, wherein the first transmission member 311 in one transmission assembly 31 is clamped with the second transmission member 312, and the first transmission member 311 in the other transmission assembly 31 is rotationally connected with the second transmission member 312. In the transmission assembly 31 where the first transmission member 311 and the second transmission member 312 are rotationally connected, when the first boss 3111 and the second boss 31211 are staggered, the elastic member 313 is in a free state, and when the first boss 3111 and the second boss 31211 are opposite to each other, the elastic member 313 is in a compressed state; in the transmission assembly 31 where the first transmission member 311 and the second transmission member 312 are clamped, the elastic member 313 is always in a natural state.

[0057] Furthermore, the tube body 21 has two cavities 211 , one cavity 211 is disposed opposite to an axle seat 221 , and the first mounting platform 4 and the second mounting platform 5 are respectively located in the two cavities 211 .

[0058] Specifically, the two cavities 211 are respectively arranged relative to two different shaft seats 221 , and different lipsticks can be installed in the two different cavities 211 , respectively, so that the two lipstick accommodating spaces are relatively independent.

[0059] Please also read Fig. 9 , Fig. 9 It is a cross-sectional view of the lower shell. Furthermore, the inner wall of the lower shell 12 is provided with a first gear tooth 121 , the outer wall of the first transmission member 311 is provided with a second gear tooth 3112 , and the first gear tooth 121 is meshed with the second gear tooth 3112 .

[0060] In this way, the transmission connection between the lower shell 12 and the first transmission member 311 is achieved by providing the gear teeth.

[0061] Furthermore, the seat body 22 has two limiting posts 222 , and the two limiting posts 222 are respectively located at the axis centers of the two shaft seats 221 .

[0062] Specifically, the elastic member 313 is a spring, and the two elastic members 313 are respectively sleeved on the two limiting pillars 222 .

[0063] In this way, when the first transmission member 311 rotates, the first transmission member 311 and the base squeeze the elastic member 313, and the elastic member 313 is affected by the friction force of the first transmission member 311, so that the elastic member 313 rotates relative to the base. The setting of the limit column 222 can play a guiding role when the elastic member 313 rotates.

[0064] Furthermore, a groove 122 is formed on the inner wall of the lower shell 12 , and a third boss 212 is formed on the outer wall of the tube body 21 . The third boss 212 extends into the groove 122 .

[0065] In this way, the elastic force of the elastic member 313 in the compressed state can be prevented from pushing the lower shell 12 away from the inner tube 2 .
