Description

Technical Field

[0001] This utility model belongs to the field of sketching and drawing technology, and in particular relates to a press-type charcoal pencil for sketching and drawing. Background Technology

[0002] Charcoal pencils are a traditional drawing tool commonly used in sketching, drawing, and drafting. They are characterized by their bold strokes, high blackness, and good elasticity, making them particularly suitable for depicting tonal variations and line changes. In art creation and teaching, charcoal pencils are widely used in art schools, studios, and individual studios due to their natural material and good controllability.

[0003] The most common type of charcoal pencil on the market is the wood-encased type, where the charcoal core is encased in a shaped wooden shell to form a complete charcoal pencil. These pencils require frequent sharpening to maintain good writing or drawing results. The charcoal core is relatively soft and easily wears down and dulls during use, making frequent sharpening a common practice.

[0004] However, this type of traditional charcoal pencil has the following drawbacks: 1. Significant material waste: Each sharpening not only removes part of the charcoal core but also a certain length of the wooden outer shell. With increased usage, this irreversible reduction causes the pencil to shorten rapidly, affecting its feel and stability, and sometimes requiring replacement before the core is fully utilized, resulting in resource waste. 2. Limited lifespan: Because each sharpening reduces the overall length of the pencil, once it reaches a certain length, it becomes difficult to hold properly, reducing hand comfort and affecting drawing stability and precision, further limiting the pencil's lifespan. 3. Low efficiency: Frequent sharpening not only wastes time and disrupts the continuity and focus of drawing but also requires additional sharpening tools, increasing the complexity of the drawing environment. This problem is particularly pronounced in scenarios requiring high efficiency, such as sketching or outdoor painting. Utility Model Content

[0021] Figure 1-8This invention illustrates an embodiment of a press-type charcoal pencil for sketching and drawing, comprising a vertical pencil sleeve 1. The inner cavity at the bottom of the vertical pencil sleeve 1 is threaded, and a tapered pencil tip 2 is fixedly connected to the bottom of the vertical pencil sleeve 1 via the thread. An inner lead holder 3 is fixedly connected to the inner cavity of the tapered pencil tip 2. A lead chuck base 4 is rotatably connected to the inner cavity of the vertical pencil sleeve 1, and the lead chuck base 4 is located at the bottom of the inner cavity of the vertical pencil sleeve 1. A support connecting tube 5 is located directly above the lead chuck base 4. The support connecting tube 5 is slidably connected to the inner cavity of the vertical pencil sleeve 1, and a lead chuck 6 is fixedly connected to the bottom of the inner cavity of the support connecting tube 5. A metal retaining ring 7 is fitted onto the surface of the lead chuck 6, and the surface of the lead chuck 6 is slidably connected to the inner cavity of the metal retaining ring 7. The metal retaining ring 7 is located at the bottom of the surface of the lead chuck 6. The metal retaining ring 7 is rotatably connected to the inner cavity of the pen refill clip base 4. A spring 8 is connected between the support connecting tube 5 and the pen refill clip base 4. A plastic pen tube 9 is slidably connected to the top of the inner cavity of the support connecting tube 5. A pen tube top support 10 is sleeved on the top of the plastic pen tube 9. The surface of the pen tube top support 10 is slidably connected to the inner cavity of the vertical pen sleeve 1. The bottom end of the charcoal pen refill 11 passes through the inner cavity of the inner pen refill support 3 to the bottom of the conical pen tip 2. The charcoal pen refill 11 is slidably connected to the inner cavity of the plastic pen tube 9. A pen sleeve bottom ring 12 is fixedly connected to the bottom of the vertical pen sleeve 1. The conical pen tip 2 is located below the pen sleeve bottom ring 12. The pen refill clip base 4 is located above the pen sleeve bottom ring 12. A top support eraser 17 is slidably connected to the inner cavity of the pen tube top support 10. The surface of the vertical pen sleeve 1 is provided with a facet 18.

[0022] By adopting the above solution: the setting of the facet 18 of this utility model can increase the friction between the surface of the vertical pen cap 1 and the hand of the person holding the vertical pen cap 1 when the person holds it, and can reduce the occurrence of the vertical pen cap 1 slipping off the person's hand due to the surface of the vertical pen cap 1 being too smooth.

[0023] refer to Figure 1 , Figure 6 and Figure 7 The inner cavity of the supporting connecting tube 5 is fixedly connected to a pen refill clamp limiting ring 13, which is located at the top of the pen refill clamp 6. The inner cavity of the supporting connecting tube 5 is fixedly connected to a plastic pen tube limiting ring 14, which is located at the bottom of the plastic pen tube 9. The inner cavity of the vertical pen sleeve 1 is fixedly connected to an inner liner sleeve 15. The supporting connecting tube 5 and the pen refill clamp base 4 are both provided with annular limiting grooves 16 on opposite sides. The top and bottom ends of the spring 8 are both fitted into the inner cavity of the annular limiting grooves 16. A rubber pad 19 is fitted on the bottom of the surface of the vertical pen sleeve 1.

[0024] By adopting the above solution: the rubber pad 19 of this utility model makes the contact surface between the painter's fingers and the edge 18 softer, which can avoid the painter's fingers from hurting due to holding the edge 18 for a long time.

[0025] Working Principle: When using this invention, the user pulls out the top-mounted eraser 17, then inserts the charcoal pencil lead 11 into the inner cavity of the top-mounted pencil tube 10. The user then presses the top-mounted pencil tube 10 repeatedly. During this process, the top-mounted pencil tube 10 pushes the plastic pencil tube 9, which slides downwards under the limiting support of the inner sleeve 15. Simultaneously, the plastic pencil tube 9 drives the supporting connecting tube 5 to slide downwards, causing the supporting connecting tube 5 to push the pencil lead clamp 6 downwards. At this time, the position of the metal fixing ring 7, which is limited by the bottom support 4 of the pencil lead clamp, remains fixed. This releases the metal fixing ring 7 from its constricting force on the pencil lead clamp 6, allowing the pencil lead clamp 6 to unfold. Then, under the action of gravity... The charcoal lead 11 will slide downwards naturally. Then, the rebound force of the spring 8 pushes the support connecting tube 5 to return to its original position and slide upwards. This pulls the lead clip 6 upwards, and under the tightening action of the metal retaining ring 7, the lead clip 6 closes again, thus fixing the charcoal lead 11 in place until the bottom of the charcoal lead 11 slides out below the conical tip 2. Then, the bottom of the charcoal lead 11 can be sharpened as needed for drawing. When the tip length is insufficient, hold the vertical pen cap 1 and press the pen tube top support 10 once. Repeat the above principle to keep the lead at the appropriate length. Moreover, this pen can be easily dispensed with one hand, making drawing more convenient.

[0026] In summary, this press-type charcoal pencil for sketching and drawing works by holding the vertical pencil cap 1 and pressing the top support 10, which pushes the plastic pencil tube 9 to slide the supporting connecting tube 5 downwards. This causes the supporting connecting tube 5 to push the lead clip 6 downwards and unfold it. Under the influence of gravity, the charcoal lead 11 will naturally slide downwards. Then, the rebound force of the spring 8 pushes the supporting connecting tube 5 back to slide upwards, which in turn pulls the lead clip 6 upwards. Under the tightening action of the metal retaining ring 7, the lead clip 6 closes again, thus fixing the charcoal lead 11 back in place. This makes it very convenient to eject the lead, making drawing more efficient.

[0027] The technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the utility model in order to achieve the purpose of the utility model.
