Description

Technical Field

[0001] This utility model relates to the field of colored pencil technology, and in particular to a rotating colored pencil structure with integrated combination and disassembly functions. Background Technology

[0002] Colored pencils are drawing pencils made using colored pigments instead of graphite. They are manufactured in the same way as regular pencils, mixing pigments with a clay binder. Colored pencils are available in many brands and a wide range of colors, and come in two types: water-soluble and insoluble. Water-soluble colored pencils can be colored with water and a brush after drawing, producing a watercolor-like effect, while insoluble colored pencils do not have this property. Children often use colored pencils in their drawing process.

[0003] Existing colored pencils have the following shortcomings:

[0004] Firstly, traditional colored pencils on the market require a sharpener after the lead is depleted to continue use. However, since children are the primary users of colored pencils, the metal blades of sharpeners pose a safety hazard of cutting fingers, which is even more dangerous for children lacking experience. Furthermore, the sharpening process is cumbersome, requiring manual holding of the pencil and repeated rotation, which not only prolongs preparation time but also risks lead breakage and material waste due to improper operation. This reliance on sharpeners increases safety risks for children and reduces efficiency, causing significant inconvenience for users.

[0005] Secondly, current colored pencils incur relatively high production costs to balance aesthetics and performance. However, these pencils have significant design limitations: once the lead tip is exhausted, the remaining pencil barrel is unusable and must be discarded. This "disposable" characteristic means that the initial material and production costs are not fully utilized, resulting in the waste of a large number of usable pencil barrels. This not only leads to unnecessary resource consumption but also increases the economic cost of long-term use. Therefore, there is an urgent need to improve the structure or materials of existing colored pencils to solve the resource waste problem and improve the product's cost-effectiveness.

[0006] Therefore, it is necessary to design a rotating colored pencil structure that integrates combination and disassembly functions to solve the problems mentioned above. Utility Model Content

[0007] The purpose of this invention is to provide a rotating colored pencil structure with integrated combination and disassembly functions to solve the problem of colored pencils being inconvenient to use as mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a rotating colored pencil structure with integrated combination and disassembly functions, comprising a colored pencil body; the colored pencil body has an internal receiving groove, and a movable extension body is movably connected inside the receiving groove; a connecting block is fixed to the top of the movable extension body, and a colored pencil tip is fixed to the top of the connecting block; a threaded groove is opened inside the movable extension body; a threaded rod is rotatably connected inside the receiving groove, and the threaded rod is threadedly connected to the threaded groove; a knob is rotatably connected to the bottom of the colored pencil body, and anti-slip protrusions are fixed to the outer side of the knob.

[0009] Preferably, the cross-section of the anti-slip ridges is semi-circular, and they are arranged at equal intervals on the outside of the knob.

[0010] Preferably, guide blocks are fixed on both sides of the movable extension body, and guide grooves are provided on the inner side of the colored pencil body, and the guide grooves are slidably connected to the guide blocks.

[0011] Preferably, a locking block is fixed at one end of the connecting block near the movable extension body, and a locking groove is provided at one end of the movable extension body near the connecting block, and the locking groove is engaged with the locking block.

[0012] Preferably, a fixing mechanism is provided inside the movable extension on one side of the slot. The fixing mechanism includes an internal groove, and the internal grooves are all located inside the movable extension. A damping movable block is movably connected inside the internal groove, and a fixing block is fixed on one side of the damping movable block. A fixing groove is opened inside the slot, and the fixing groove is engaged with the fixing block. A spring is connected to the side of the damping movable block away from the fixing block, and its other end is connected to the inner wall of the internal groove. A pull ring is fixed to the top of the damping movable block. A through groove is opened at the top of the movable extension on one side of the connecting block, and the pull ring moves inside the through groove.

[0013] Preferably, the size of each card block is equal to the size of the card slot, and the cross-sections of both the card block and the card slot are trapezoidal.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the integrated combination and disassembly function of the rotating colored pencil structure not only realizes the combination and disassembly function, but also realizes the rotational extension function;

[0015] By rotating the knob and engaging the threaded connection, the movable extension body and the colored pencil tip at the top extend from inside the colored pencil body. After the exposed section is used up, the user can simply rotate the knob to push the colored pencil tip forward for easy use. The user does not need to use a pencil sharpener to remove the pencil tip, which not only saves time but also reduces the risk associated with pencil sharpeners. The knob makes it easy for the user to rotate the pencil. The colored pencil shell is made of a combination of high-strength engineering plastic (ABS / PC) and metal, which improves impact resistance. The cylindrical receiving groove, combined with the guide block and guide groove structure, disperses stress and ensures linear movement.

[0016] By pulling the ring and engaging the locking mechanism between the locking block and the slot, a new colored pencil tip is inserted into the top of the movable extension. Under the elastic action of the spring, the fixing block is then inserted into the fixing slot, thus achieving a limiting and fixing effect. When the colored pencil tip is used up, it can be replaced simply by using the fixing mechanism, extending the lifespan of the colored pencil tip and eliminating the need to replace the entire colored pencil, thereby saving resource costs.

A connecting block 5 is fixed to the top of the movable extension body 4, and a colored pencil tip 1 is fixed to the top of the connecting block 5. A threaded groove 7 is opened inside the movable extension body 4. A threaded rod 9 is rotatably connected inside the receiving groove 10, and the threaded rod 9 is threadedly connected to the threaded groove 7. A knob 12 is rotatably connected to the bottom end of the colored pencil body 3, and the outer side of the knob 12... All are fixed with anti-slip ridges 6, the cross-section of which is semi-circular. They are evenly spaced on the outside of the knob 12. Guide blocks 11 are fixed on both sides of the movable extension body 4. Guide grooves 8 are provided on the inner side of the colored pencil body 3. The guide grooves 8 are slidably connected to the guide blocks 11. A locking block 13 is fixed at the end of the connecting block 5 near the movable extension body 4. A locking groove 14 is opened at the end of the movable extension body 4 near the connecting block 5. The locking groove 14 is engaged with the locking block 13.

[0027] In this embodiment, when the exposed section of the colored pencil is used up, the knob 12 is turned to rotate the receiving groove 10. Under the action of the threaded connection, the movable extension body 4 further extends the colored pencil tip 1 at the top, so that the rear end of the colored pencil tip 1 is exposed for the user to use. This brings convenience to the staff and also reduces the risk factor of pencil sharpeners, further improving the practicality of colored pencils.

The fixing mechanism 15 includes an internal groove 1501, and the internal grooves 1501 are all located inside the movable extension 4. A damping movable block 1505 is movably connected inside the internal groove 1501, and a fixing block 1506 is fixed on one side of the damping movable block 1505. A fixing groove 1503 is opened inside the locking block 13, and the fixing grooves 1503 are all engaged with the fixing blocks 1506.
