[0027] 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.

[0028] Reference Figures 1 to 3 This utility model provides an embodiment of a detachable tape core structure, including a core 1. The top of the core 1 has a groove 11, which can be adapted to a positioning slider. The positioning slider moves within the groove 11, which can precisely control the disassembly of the core 1, allowing the disassembly of the core 1 to be effectively lifted. A fixing rod 2 is fixedly connected inside the core 1. The fixing rod 2 can stabilize the internal structure and ensure that the parts connected to it maintain a precise trajectory when moving, avoiding shaking or deviation, and providing a guarantee for the stable connection between the core 1 and the parts.

[0029] The fixed rod 2 has two sliding rods 3 internally connected. The flexible sliding of the two sliding rods 3 within the fixed rod 2 is the core of realizing the detachable function of the core 1, making the installation and removal of the core 1 easy and convenient. The two sliding rods 3 are fixedly connected to a spring 4 at their adjacent ends. The spring 4 has excellent elasticity. When the core 1 is installed, it is compressed and stores energy. When the core 1 is fixed, it releases elastic potential energy, pushing the sliding rods 3 outward, so that they are tightly locked in the part, and the core 1 is securely fixed.

[0030] A sliding ring 5 is fixedly connected to the outer side of the core 1. The sliding ring 5 serves as a transition bridge between the core 1 and the fixed ring 6, allowing the core 1 to slide smoothly relative to the fixed ring 6. It can also effectively disperse external pressure and protect the core 1 from damage in all directions. The sliding ring 5 has a hole 7 inside. This hole 7 fits tightly with the hole 7 inside the fixed ring 6 and the sliding rod 3. It is the key hub for the installation and disassembly of the core 1. The sliding rod 3 connects and separates the core 1 from the fixed ring 6 by entering and exiting the hole 7.

[0031] A fixed ring 6 is slidably connected to the outer side of the sliding ring 5. The fixed ring 6 serves as an external support frame, protecting the internal structure and providing a solid installation base for the protective components. It can withstand certain external forces and ensure the safe use of internal components such as the core 1. The fixed ring 6 has a hole 7 inside, and the outer side of the sliding rod 3 is slidably connected inside the hole 7. This connection method allows the core 1 to be stably fixed inside the fixed ring 6, and it can be easily disassembled by moving the sliding rod 3. A protective component for protecting the object is rotatably connected to the outer side of the fixed ring 6.

[0032] Reference Figure 1 , Figure 2 , Figure 4 The protective component includes an outer layer 8, which is a silicone paper layer. With its excellent non-stick properties, the silicone paper can prevent the tape from sticking to other objects when not in use, and allows the tape to be easily peeled off from the release paper when in use, significantly improving the convenience and cleanliness of tape use. The outer side of the outer layer 8 is rotatably connected to the outer side of the fixing ring 6. The rotatable connection allows the outer layer 8 to rotate flexibly on the fixing ring 6, so that the tape is not hindered when in use, ensuring that the normal use process of the tape is not obstructed.

[0033] The outer layer 8 has an internal fixed connection with a protective layer 9, which is made of fiber cloth. The fiber cloth has high strength and modulus, can withstand greater tensile and compressive forces, and is not easily deformed or damaged. After being made into tape, it can be used in fixing scenarios with high strength requirements, ensuring that the tape will not easily break during use and providing a reliable fixing effect. The protective layer 9 has an internal fixed connection with an inner liner 10, which is made of acrylic ester. The inner liner 10 has good adhesion, weather resistance, and transparency, and can achieve firm adhesion to a variety of materials. It can maintain stable adhesion under different climatic conditions, and its good transparency will not affect the appearance of the object being pasted.

[0034] Working principle: When the operator needs to remove the core 1 from the inside of the fixing ring 6, they can squeeze the handle connected to the outside of the sliding rod 3 inward. The handle moves the sliding rod 3, which then disengages from the inside of the fixing ring 6 and the sliding ring 5. Both the fixing ring 6 and the sliding ring 5 have holes 7 inside. When the sliding rod 3 leaves the hole 7 inside the fixing ring 6, the sliding ring 5 and the core 1 can be removed from the inside of the fixing ring 6. When the core 1 needs to be installed back into the inside of the fixing ring 6, the handle can be used again to move the sliding rod 3 so that the outside of the sliding rod 3 enters the inside of the sliding ring 5, and the sliding ring 5 is placed back into the inside of the fixing ring 6. Once the sliding ring 5 is placed back into the inside of the fixing ring 6, the handle can be released. The compressed spring 4 will push the two sliding rods 3 outward, thus returning the sliding rods 3 back into the inside of the fixing ring 6, thereby achieving the disassembly of the core 1.

[0035] The outer layer 8, composed of silicone paper coated with an organic silicone layer, is wrapped around the outside of the retaining ring 6. This outer layer 8 provides excellent non-stick properties, effectively preventing the tape from adhering to other objects when not in use, while allowing for easy peeling of the tape from the release paper during use. A protective layer 9, composed of fiber cloth, is fixedly connected to the inner side of the outer layer 8. Fiberglass cloth has high strength and modulus, meaning it can withstand significant tensile and compressive forces without easily deforming or being damaged. After being made into tape, it can be used in applications requiring high-strength fixing or binding, such as securing industrial equipment or packaging heavy items. It ensures the tape will not easily break during use, providing a reliable fixing effect. An inner liner 10, composed of acrylic esters, is fixed inside the protective layer 9. Acrylic esters have good adhesion, weather resistance, and transparency, exhibiting good adhesion to various materials and stable performance after curing. It can be used for various packaging tapes, label tapes, etc.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
