[0005] This invention aims to overcome the shortcomings of existing oil pastels, such as complex structure, easy failure, and waste of materials, and provides a simplified, stable, energy-saving and environmentally friendly telescopic children's oil pastel.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A retractable children's oil pastel, including

[0008] Fixed casing;

[0009] A rotating inner cylinder is fitted with a fixed outer shell, and an oil pastel is inserted into the rotating inner cylinder.

[0010] A movable top plate is inserted into a rotating inner cylinder. The oil pastel body abuts against the movable top plate. The movable top plate is connected to a slider, which is threadedly connected to the rotating inner cylinder. The rotating inner cylinder is provided with a guide hole, and the slider is connected to the guide hole for lifting.

[0011] Fasteners are used to connect the fasteners to the wall of the rotating inner cylinder.

[0012] Anti-slip component, the anti-slip component is connected to the rotating inner cylinder, and the anti-slip component is rotatably connected to one end of the fixed outer shell;

[0013] The protective cover is detachably connected to the other end of the fixed outer shell.

[0014] The rotating inner cylinder is placed inside the fixed outer shell to hold the oil pastels. The inserted oil pastels abut against the movable top plate of the rotating inner cylinder. As the rotating inner cylinder and the fixed outer shell rotate relative to each other, the movable top plate rises along the guide hole, gradually pushing the oil pastels out of the rotating inner cylinder. This allows for the storage of oil pastels and the extension to the desired length for use. It protects the oil pastels, prevents them from getting dirty when not in use, and ensures safe use by children. It also facilitates easy replacement of oil pastel refills, enabling recycling, saving resources and materials, and achieving environmental sustainability. The design incorporates several features: Fasteners are attached to the inner wall of the rotating inner cylinder to secure the oil pastels, preventing them from shifting within the cylinder and facilitating replacement; an anti-slip component connects to the rotating inner cylinder, allowing for rotation on the fixed outer shell; the anti-slip design increases the pressure point to accommodate children's pressure; and an anti-slip cover connects to the other end of the fixed outer shell to seal the rotating inner cylinder, protecting the oil pastels from moisture and dust. After use, the oil pastels can be manually reset by applying force through the cover, simplifying the structure and enhancing operation. This design achieves the goals of convenient and safe use of oil pastels, simplified structure, resource conservation and environmental friendliness, enhanced stability, and extended lifespan.

[0015] Preferably, at least two guide holes are provided and arranged opposite each other. One end of the guide hole wall has an upper stop groove, and the other end of the guide hole wall has a lower stop groove. By creating grooves at both ends—the upper and lower stop grooves—the guide holes restrict the movement of the slider, thereby limiting the position of the moving top plate and preventing the crayon from being pushed out of the rotating inner cylinder. This achieves the effect of improving operational accuracy and stability.

[0016] Preferably, the slider includes a connecting plate and a connecting rod. One end of the connecting rod is connected to the movable top plate, and the other end extends out of the guide hole and connects to one side of the connecting plate. The other side of the connecting plate is provided with a threaded groove, and the inner wall of the fixed shell is provided with a threaded groove that matches the first threaded groove. The connecting plate is threadedly connected to the fixed shell. The connecting rod in the slider is inserted into the guide hole and connects the inner movable top plate and the outer connecting plate. The first and second threaded grooves are multiple regularly arranged spiral grooves to improve the contact surface and tightness between the connecting plate and the inner wall of the fixed shell, and to prevent retraction due to excessive force applied to the oil pastel. This achieves the effect of improving the stability of the oil pastel during use.

[0017] Preferably, one end of the fixed outer shell is provided with an insertion hole, and the anti-slip component includes a rotating rod that inserts into the insertion hole. The end face of the rotating inner cylinder is provided with a slot, and the rotating rod is connected to an insert rod that engages with the slot. The end face of the fixed outer shell is connected to the rotating rod of the anti-slip component through the insertion hole, allowing the rotating rod to rotate stably on the fixed outer shell. The end of the rotating rod is connected to an insert rod, which is a rod-shaped structure with a rectangular cross-section. This allows the rotating inner cylinder to rotate as the rotating rod rotates after being inserted into the slot, facilitating quick assembly between the structures. This improves the efficiency and stability of the structural operation and assembly.

[0018] Preferably, the anti-slip component includes an anti-slip plate, with the other end of the rotating rod detachably connected to the anti-slip plate. The anti-slip plate has several anti-slip grooves. The anti-slip plate is detachably fixed to the end of the rotating rod extending from the insertion hole. The anti-slip plate has a sheet-like structure to prevent slippage during rotation, and the anti-slip grooves further enhance contact friction to facilitate child operation. This improves ease of use.

[0019] Preferably, the end face of the rotating rod is provided with a positioning groove, and the anti-slip plate is inserted into the positioning groove. Both the rotating rod and the anti-slip plate are provided with through holes, and fixing bolts are inserted into the through holes. The fixing bolts are threadedly connected to fixing nuts. The fixing bolts pass through the through holes on one side of the rotating rod, the through hole of the anti-slip plate, and the through hole on the other side of the rotating rod, and are connected to the fixing nuts to stably assemble the anti-slip plate onto the rotating rod. This simplifies the structure and facilitates quick assembly and disassembly, thereby improving the efficiency of structural assembly and facilitating reusability.

[0020] Preferably, several fasteners are provided, and the fasteners are evenly distributed on the inner wall of the rotating inner cylinder. The presence of several fasteners and their even distribution on the inner wall of the rotating inner cylinder ensures that the oil pastel body is evenly fixed with force, thereby improving the structural connection strength of the oil pastel body.

[0021] Preferably, the protective cover has an inner groove connected to a buffer plate. The buffer plate, connected to the inner groove, applies force to the oil pastel, pushing it back into the rotating inner cylinder, reducing hard contact and preventing damage. The recessed inner groove allows the end of the oil pastel to extend out of the fixed outer shell, so that it can be used directly after opening the protective cover next time. This achieves the effect of protecting the oil pastel and improving ease of use.

[0022] The beneficial effects of this utility model are: oil pastels are convenient and safe to use; the structure is simplified, resources and materials are saved, and it is environmentally friendly; the stability of use is enhanced and the life of oil pastels is extended; the stability of oil pastels is improved; and the oil pastels are protected and their ease of use is increased.
