[0002] Lipstick is a kind of cosmetic used to apply on the lips to increase the vividness of lip color and modify the lip shape. At the same time, it also provides moisture and protection for the lips. There are many different types and textures of lipsticks. The choice of lipstick should be combined with skin color, lip condition, makeup style and occasion. At the same time, pay attention to factors such as the texture, durability and moisturizing degree of the lipstick. Before using the lipstick, it is recommended to apply lip primer or lip gloss and other lip care products for protection and moisturizing to obtain a better makeup effect and comfort.

[0003] In the existing related technologies, there are often the following defects: Lipsticks usually consist of two parts, a lipstick tube and a middle core. The middle core is the part where the lipstick is applied and will be gradually consumed during use.

The end sides of the two connecting rods are fixedly connected with a groove plate. A row of barbs is uniformly fixedly connected to the inside of the groove plate.

[0007] The effects achieved by the above components are as follows: The sliding of the slider inside the sliding groove plays a role in restricting the moving direction of the two connecting rods. The connecting rods will drive the groove plate to press against the side wall of the middle core body, and the barbs will insert into the inside of the middle core body.

[0008] Preferably, the barb is of an arc structure.

[0009] The effects achieved by the above components are as follows: The middle core body will be inserted upside down on the surface of the arc-shaped barbs, thereby improving the stability of the middle core body after replacement during use.

[0010] Preferably, the other ends of the two connecting rods are fixedly connected with fixing blocks, the surface of the base is fixedly connected with sliding pins, the side walls of the sliding pins are slidably connected with limiting frames, and both ends of the limiting frames are bent structures.

[0011] The effect achieved by the above components is that the limiting frame will simultaneously push the two fixing blocks to move towards the side close to each other.

[0012] Preferably, a screw rod is threadedly connected inside the limiting frame, and the screw rod is rotatably connected inside the base.

[0013] The effect achieved by the above components is that when the screw rod is rotated, the screw rod will drive the limiting frame to move.

[0014] Preferably, a roller is rotatably connected inside the fixing block.

[0015] The effect achieved by the above components is that relative movement occurs between the limiting frame and the roller, reducing the friction when relative movement occurs between the limiting frame and the fixing block.

[0016] Preferably, a spring is fixedly connected between the chute and the slider.

[0017] The effect achieved by the above components is that when the screw rod is rotated in the reverse direction, the slider will be reset under the action of the spring force of the spring, and the groove plate will retract inside the reserved groove.

[0018] In summary:

[0019] In the present utility model, when the middle bundle core body is subjected to a pulling force, the middle bundle core body will be inserted reversely on the surface of the barbs of the arc structure, thereby improving the stability of the middle bundle core body during use after replacement, and further realizing the fixing work of the middle bundle core body after replacement. By setting the above structure, it is convenient to flexibly disassemble and replace the middle bundle core body inside the pipe body, avoiding the direct discard of the pipe body, and to a certain extent avoiding unnecessary waste.

[0025] Refer to Figures 1-4 As shown in the figure, the present utility model provides a technical solution: a replaceable middle beam core lipstick tube, including a tube body 1, a driving rod 5 is rotatably connected to the inner side of the tube body 1, a base 4 is slidably connected to the inner side of the tube body 1, the surfaces of the base 4 and the driving rod 5 are threadedly connected, and a middle beam core body 2 is detachably installed on the surface of the base 4.

[0026] Next, the overall specific settings and functions will be specifically described.

[0027] In this implementation: two chutes 10 are opened on the surface of the base 4, two reserved grooves 6 are opened inside the base 4 body, the inner wall of the chute 10 is slidably connected with a slide block 11, two connecting rods 9 are fixedly connected inside the slide block 11, two ends of the two connecting rods 9 are fixedly connected with a grooved plate 7, and a row of barbs 8 are uniformly fixedly connected inside the grooved plate 7. The sliding of the slide block 11 inside the chute 10 plays a role in restricting the moving direction of the two connecting rods 9. The connecting rods 9 will drive the grooved plate 7 to press against the side wall of the middle beam core body 2, and the barbs 8 will insert into the inside of the middle beam core body 2.

[0028] The barbs 8 are of an arc structure. The middle beam core body 2 will be inserted upside down on the surface of the arc-shaped barbs 8, thereby improving the stability of the middle beam core body 2 after replacement. The other ends of the two connecting rods 9 are fixedly connected with a fixed block 13, a slide pin 16 is fixedly connected to the surface of the base 4, the side wall of the slide pin 16 is slidably connected with a limiting frame 12, and both ends of the limiting frame 12 are bent structures. The limiting frame 12 will simultaneously push the two fixed blocks 13 to move towards each other.

[0029] Specifically, a screw 17 is threadedly connected inside the limiting frame 12, and the screw 17 is rotatably connected to the inside of the base 4. Rotating the screw 17 will drive the limiting frame 12 to move.

[0030] A roller 14 is rotatably connected inside the fixed block 13. Relative movement occurs between the limiting frame 12 and the roller 14, reducing the friction when relative movement occurs between the limiting frame 12 and the fixed block 13. A spring 15 is fixedly connected between the chute 10 and the slide block 11. Rotating the screw 17 in the reverse direction, the slide block 11 will be reset under the elastic force of the spring 15, and the grooved plate 7 will retract inside the reserved groove 6.

[0031] Working principle: When it is necessary to replace the middle beam core body 2 that is about to be used up, first rotate the driving rod 5 to turn out the base 4 from the inside of the pipe body 1. After removing the middle beam core body 2 that is about to be used up, sleeved the new middle beam core body 2 on the inside of the base 4, which can realize the preliminary positioning work of the middle beam core body 2. At this time, rotate the screw rod 17, and the screw rod 17 will drive the limit frame 12 to move. The limit frame 12 slides on the surface of the sliding pin 16, which plays a role in restricting the moving direction of the limit frame 12. The limit frame 12 will simultaneously push the two fixing blocks 13 to move towards the side close to each other. Among them, relative movement occurs between the limit frame 12 and the roller 14, reducing the friction force when relative movement occurs between the limit frame 12 and the fixing block 13. Among them, the slider 11 slides inside the chute 10, which plays a role in restricting the moving direction of the two connecting rods 9. The connecting rod 9 will drive the groove plate 7 to press against the side wall of the middle beam core body 2, and the barbs 8 will insert into the inside of the middle beam core body 2. When the middle beam core body 2 is subjected to a pulling force, the middle beam core body 2 will be inserted inversely on the surface of the arc-shaped barbs 8, thereby improving the stability of the middle beam core body 2 during use after replacement, and then realizing the fixing work of the middle beam core body 2 after replacement. Rotate the screw rod 17 in the reverse direction, and the slider 11 will be reset under the elastic force of the spring 15, and the groove plate 7 will retract into the inside of the reserved groove 6, so as to realize the disassembly work of the middle beam core body 2 that needs to be replaced. By setting the above structure, it is convenient to flexibly disassemble and replace the middle beam core body 2 inside the pipe body 1, avoiding the direct discard of the pipe body 1, and to a certain extent avoiding unnecessary waste.
