Description

Technical Field

[0001] This utility model relates to the technical field of double eyelid tape storage boxes, specifically a roll-up double eyelid tape storage box. Background Technology

[0002] The roll-up double eyelid tape storage box is a portable tool specifically designed for storing and organizing double eyelid tape. Its design feature is that it organizes the double eyelid tape in an orderly manner by "rolling it up," avoiding the problems of sticking, deformation, or contamination caused by traditional loose or flat storage.

[0003] The utility model patent application with publication number "CN220663555U" discloses a double eyelid tape dispensing tool, which mainly consists of a material storage box, a storage shaft, a drive wheel, and a material guide plate. This technical solution will not cause leakage or drop, ensuring that the double eyelid tape is picked up neatly, orderly, and safely. In addition, the user only needs to turn the drive wheel to feed out the double eyelid tape, which meets the needs of double eyelid tape picking. The operation is convenient and labor-saving, and the user experience is excellent.

[0004] The double eyelid tape ejector tool disclosed in the above document has the following defects: the arc-shaped shaft plate in this technical solution needs to achieve expansion and locking with the sleeve through plastic deformation, which means that the user must apply an axial pulling force exceeding the material yield strength to separate the components. This violent disassembly will not only cause brittle fracture at the root of the arc-shaped shaft plate due to stress concentration (especially in low temperature environments), but will also cause the shaft plate to permanently lose its elastic expansion function due to accumulated plastic deformation during repeated loading and unloading, ultimately causing irreversible damage to the core components of the product and completely ending the life cycle of the reusable version. Utility Model Content

[0005] The purpose of this utility model is to provide a roll-up double eyelid tape storage box, which solves the problem that the sleeve and storage shaft of the existing double eyelid tape dispensing tool are interference-fitted, requiring users to pull hard when disassembling, which easily damages the arc-shaped shaft plate.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a roll-up double eyelid tape storage box, comprising an upper shell, a lower shell fitted to one end of the upper shell, the upper and lower shells forming a storage cavity, both the outer surfaces of the upper and lower shells having a discharge port and an opening, the inner surface of the lower shell having an mounting plate, a discharge guide plate, and a connecting shaft, the outer surface of the connecting shaft having a drive wheel mounted thereon, one end of the drive wheel being located inside the opening, the storage cavity having a storage box inside, one end of the storage box having a connecting groove, the mounting plate being fitted inside the connecting groove, the outer surface of the storage box having a notch, the inner surface of the storage box having a storage shaft, one end of the storage shaft having an mounting groove, the mounting groove having a pressing and tightening component inside, and the outer surface of the pressing and tightening component having a sleeve.

[0008] Furthermore, one end of the storage shaft has two grooves, and the inner surface of the mounting groove has an L-shaped limiting groove. One end of the storage shaft is fitted with a cover plate, and one end of the cover plate is provided with two limiting blocks. The two limiting blocks are fitted into the corresponding grooves.

[0009] Furthermore, the pressing and tightening assembly includes a slide rod, one end of which is fitted with a tapered component, and the other end of which passes through the cover plate and is fitted with a knob. A limiting rod is provided on the outer surface of the slide rod, one end of which is slidably connected to the inside of an L-shaped limiting groove. Slider blocks are slidably connected to the inside of both grooves. One end of the slider is provided with an arc-shaped plate, and the other end of the slider is provided with an inclined surface. The outer surface of the inclined surface contacts the outer surface of the tapered component. The upper surface of the slider contacts the lower surface of the limiting block, and the lower surface of the slider contacts the inner surface of the groove.

[0010] Furthermore, a spring is installed at the bottom of the mounting groove, the other end of the spring is installed on the lower surface of the tapered member, a tension spring is installed between the two sliders, and a reinforcing rib is provided between the arc plate and the slider.

[0011] Furthermore, the inner surface of the lower housing is provided with an annular tooth structure extending in the circumferential direction. The annular tooth structure is in frictional contact with the end face of the drive wheel. The annular tooth structure includes multiple convex teeth, all of which are arranged inclined in the same annular direction. The rotation direction of the drive wheel is consistent with the inclination direction of the convex teeth.

[0012] Furthermore, a protective cover is provided at the upper end of the discharge port, and one end of the protective cover is hinged to the outer surface of the upper and lower housings.

[0013] This utility model has the following beneficial effects:

[0014] (1) By pushing the knob, the slide bar moves axially. The conical part squeezes the inclined surface of the slider, forcing the arc plate to expand radially and lock the sleeve. At this time, rotating the knob will lock the limit rod into the end of the L-shaped limit groove and lock the preload of the spring. When disassembling, rotating the knob in the opposite direction will release the limit, and the spring's restoring force will automatically retract the arc plate to release the tension. The sleeve can be easily removed. This process transforms the disassembly action from destructive pulling to controllable elastic deformation. The arc plate always moves within the material's yield strength, avoiding the risk of plastic fracture caused by interference fit violent pulling.

[0015] (2) The protective cover of this utility model realizes the opening and closing action through the hinge structure. When closed, it forms a physical barrier to completely seal the discharge port, preventing external dust, water vapor and microorganisms from entering the storage cavity, ensuring the sterility and long-term stability of the double eyelid tape. At the same time, it automatically avoids the discharge path when opened, and the user can achieve seamless switching between protection and use with one hand, solving the problem of contamination failure caused by exposed discharge port.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] By using the press-tightening component 7, the disassembly action can be transformed from destructive pulling into controllable elastic deformation, thus avoiding the risk of plastic fracture caused by interference fit and violent pulling.

[0028] Two grooves are provided at one end of the storage shaft 603. An L-shaped limiting groove 604 is provided on the inner surface of the mounting groove. A cover plate 9 is installed at one end of the storage shaft 603. Two limiting blocks 901 are provided at one end of the cover plate 9. Both limiting blocks 901 are installed in the corresponding grooves.

[0029] The pressing and tightening assembly 7 includes a slide rod 701. One end of the slide rod 701 is equipped with a tapered part 702. The other end of the slide rod 701 passes through the cover plate 9 and is equipped with a knob 703. The outer surface of the slide rod 701 is provided with a limiting rod 704. One end of the limiting rod 704 is slidably connected to the inside of the L-shaped limiting groove 604. The inside of both grooves is slidably connected with sliders 705.

[0032] A protective cover 11 is provided at the upper end of the discharge port 3, and one end of the protective cover 11 is hinged to the outer surface of the upper shell 1 and the lower shell 2.

[0033] The protective cover 11 opens and closes via a hinged structure. When closed, it forms a physical barrier that completely seals the discharge port 3, preventing external dust, moisture, and microorganisms from entering the storage chamber. This ensures the sterility and long-term stability of the double eyelid tape. At the same time, it automatically avoids the discharge path when opened, allowing users to seamlessly switch between protection and retrieval with one hand. This solves the problem of contamination and failure caused by the exposed discharge port 3.

[0034] In use, first, the sleeve 8 of the wound material strip is fitted onto the storage shaft 603, and it is precisely positioned by its own weight. Then, the knob 703 is pushed to drive the slide bar 701 to move inward. The conical part 702 squeezes the inclined surface of the slider 705, forcing the arc plate 706 to radially elastically expand and tighten the inner wall of the sleeve 8. During this process, the tension spring 708 stretches to provide the slider 705 with a reset preload force, and the spring 707 is compressed to store energy. When the limiting rod 704 slides to the bottom of the L-shaped limiting groove 604, the knob 703 is rotated to... The limiting rod 704 is locked into the groove end and the spring 707 is pre-pressurized to maintain the tension state. Then, the assembled storage box 6 is inserted into the mounting plate 201 along the connecting groove 601. The notch 602 and the discharge guide plate 202 are automatically aligned. The first end of the material strip is manually introduced into the discharge channel between the drive wheel 5 and the guide plate through the notch 602. Finally, the upper shell 1 and the lower shell 2 are fastened together. The ring tooth structure 10 and the end face of the drive wheel 5 immediately form a one-way anti-reverse meshing, completing the whole process of non-destructive assembly.

[0035] When it is necessary to disassemble the sleeve 8, open the upper housing 1 and the lower housing 2, then take out the storage box 6, rotate the knob 703 in the opposite direction to drive the limit rod 704 to move upward along the vertical section of the L-shaped limit groove 604, release the lock, the spring 707 releases the stored energy to push the conical part 702 back, the synchronous tension spring 708 contracts and pulls the slider 705 radially inward, the arc plate 706 and the tension contact surface of the inner wall of the sleeve 8 are completely separated, at this time the sleeve 8 can be taken out from the storage box 6. There is no forced pulling action in the whole process, ensuring that the arc plate 706 only undergoes elastic deformation and never suffers plastic damage;

[0036] Afterwards, when the user needs to take out the double eyelid tape, they hold the storage box, open the protective cover 11, and use their finger (such as their thumb) to turn the drive wheel 5. Under the action of friction, the drive wheel 5 can move the double eyelid tape strip along the discharge channel under the guidance of the discharge guide plate 202 until it is sent out from the discharge port 3. By controlling the number of rotations of the drive wheel 5, the number of double eyelid tapes sent out from the discharge port 3 can be controlled. The user can then peel off the double eyelid tape from the sent-out backing paper for use.
