Description

Technical Field

[0001] This utility model relates to the technical field of pencil products, specifically to a silicone pencil. Background Technology

[0002] Pencils are common children's products and are often the first product children encounter when learning to write. Currently, many pencils come with caps to protect the tip and prevent it from scratching the pencil case.

[0003] Based on this, pencils tend to shorten after being sharpened multiple times, making them difficult to grip and write with. Therefore, pencil caps with an extension function have appeared on the market to solve this problem. These caps are placed over the end of the pencil to extend its length. However, when the pencil is already long enough, placing the cap on the end makes the pencil too long, affecting the writing experience. The cap also needs to be stored elsewhere, making it difficult to find or even lose after writing. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the present invention aims to provide a silicone pencil.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A silicone pencil includes a pencil body and a pencil cap; the pencil body has a cap fixing section at its tail, the maximum diameter of which is smaller than the maximum diameter of the pencil body; the pencil cap has a hollow inner cavity, and both ends of the pencil cap have openings communicating with the hollow inner cavity; the hollow inner cavity is divided into a small-diameter section and a large-diameter section, the shape and size of the small-diameter section matching the pencil cap fixing section and its length being the same as the pencil cap fixing section, and the shape and size of the large-diameter section matching the pencil body and its length being greater than the pencil cap fixing section.

[0007] Furthermore, the pen body includes a pen barrel and a silicone sleeve, the silicone sleeve wrapping around the outside of the pen barrel, the length of the pen barrel being longer than the length of the silicone sleeve, and the tail of the pen barrel extending outside the silicone sleeve to form a pen cap fixing section.

[0008] Furthermore, the outer surface of the pen body is provided with multiple sets of finger positioning grooves at equal intervals along the length direction. Each set of finger positioning grooves includes an index finger positioning groove, a thumb positioning groove, and a middle finger positioning groove. The index finger positioning groove, thumb positioning groove, and middle finger positioning groove are distributed along the circumference of the pen body. The position of the index finger positioning groove is slightly lower than the position of the thumb positioning groove, and the position of the middle finger positioning groove is slightly lower than the position of the index finger positioning groove.

[0009] Furthermore, the pen body has a triangular prism structure, with the index finger positioning groove, thumb positioning groove, and middle finger positioning groove respectively located on the three sides of the triangular prism.

[0010] Furthermore, the sides of the triangular prism, as well as the points where adjacent sides meet, are all curved.

[0011] The beneficial effects of this invention are as follows: By optimizing the pen cap, this utility model sets a small-diameter section and a large-diameter section in its hollow inner cavity, and sets a smaller-diameter pen cap fixing section at the tail of the pen body. This allows the pen cap to act as an extender when it is inserted from the end of the small-diameter section, but not as an extender when it is inserted from the end of the large-diameter section, and only to store the pen cap. This can meet the more diverse needs of users. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings. It should be noted that this embodiment is based on the present technical solution and provides detailed implementation methods and specific operation processes, but the protection scope of the present invention is not limited to this embodiment.

[0023] This embodiment provides a silicone pencil, such as Figure 1-10 As shown, the pen includes a pen body 1 and a pen cap 2; the pen body 1 has a pen cap fixing section 3 at its tail, and the maximum diameter of the pen cap fixing section 3 is smaller than the maximum diameter of the pen body 1; the pen cap 2 has a hollow inner cavity inside, and both ends of the pen cap 2 have openings communicating with the hollow inner cavity; the hollow inner cavity is divided into a small diameter section 4 and a large diameter section 5, the shape and size of the small diameter section 4 match the pen cap fixing section 3 and its length is the same as the pen cap fixing section 3, and the shape and size of the large diameter section 5 match the pen body 1 and its length is greater than the pen cap fixing section 3.

[0024] When the pencil is no longer needed, insert the cap from one end of the larger diameter section 5, so that the cap is on the head of the pencil body 1, as shown. Figure 1 , 4 As shown in Figure 5. When the pen cap is needed as an extender, the pen cap is placed over the outside of the pen cap fixing section 3, starting from one end of the smaller diameter section 4. Since the maximum diameter of the pen cap fixing section 3 is smaller than the maximum diameter of the pen body 1, the smaller diameter section 4 can only be placed over the outside of the pen cap fixing section 3 and cannot be further inserted into the pen body 1. Therefore, the remaining part of the pen cap serves to extend the pen body, as shown in Figure 5. Figure 6 , 8 As shown.

[0025] When the pen body does not need to be extended, the pen cap is placed over the end of the pen body 1, starting from the larger diameter section 5. The larger diameter section 5 continues downwards through the pen cap fixing section 3, then into the smaller diameter section 4, until the pen cap fixing section 3 is completely inside the smaller diameter section 4. The smaller diameter section 4 can no longer be inserted into the pen body 1, at which point the pen cap can no longer move, and the end of the pen cap is flush with the end of the pen body. At this point, the pen cap is fixed at the end of the pen body 1, but it does not serve the purpose of extending the pen body. Figure 7 , 9 As shown.

[0026] In this embodiment, the pen body 1 includes a pen barrel 6 and a silicone sleeve 7. The silicone sleeve 7 wraps around the outside of the pen barrel 6. The length of the pen barrel 6 is longer than the length of the silicone sleeve 7. The tail of the pen barrel 6 extends out of the silicone sleeve 7 and forms a pen cap fixing section 3.

[0027] The portion of the silicone sleeve 7 that fits over the outside of the pen barrel 6 forms the larger diameter section of the pen body 1. The portion of the pen barrel 6 not covered by the silicone sleeve 7 forms the smaller diameter cap-fixing section 3. The silicone sleeve improves grip comfort and increases friction when the cap is on the outside of the pen body, making the cap more secure. It should be noted that the silicone sleeve 7 is wrapped around and bonded to the pen barrel using an injection molding process.

[0028] In this embodiment, as Figure 4-7 As shown, the outer surface of the pen body 1 is provided with multiple sets of finger positioning grooves at equal intervals along its length. Each set of finger positioning grooves includes an index finger positioning groove 8, a thumb positioning groove 9, and a middle finger positioning groove 10. The index finger positioning groove 8, thumb positioning groove 9, and middle finger positioning groove 10 are distributed along the circumference of the pen body. The position of the index finger positioning groove 8 is slightly lower than the position of the thumb positioning groove 9, and the position of the middle finger positioning groove 10 is slightly lower than the position of the index finger positioning groove 8. Specifically, in this embodiment, the index finger positioning groove 8, thumb positioning groove 9, and middle finger positioning groove 10 are disposed on the silicone sleeve 7.

[0029] The index finger positioning groove 8, thumb positioning groove 9, and middle finger positioning groove help users, especially children learning to write, to position their index, thumb, and middle fingers, helping them master good writing posture. Furthermore, the multiple sets of finger positioning grooves along the length of the pencil ensure that even after the pencil is sharpened, there are still corresponding finger positioning grooves available.

[0030] Furthermore, in this embodiment, as Figure 10 As shown, the pen body 1 has a triangular prism structure, with the index finger positioning groove 8, thumb positioning groove 9, and middle finger positioning groove respectively located on the three sides of the triangular prism. More specifically, in this embodiment, the pen barrel 6 has a triangular prism structure, and the silicone sleeve 7, which wraps around the pen barrel 6, also naturally forms a triangular prism shape, with the index finger positioning groove 8, thumb positioning groove 9, and middle finger positioning groove 10 respectively located on the three sides of the silicone sleeve 7.

[0031] To ensure a comfortable grip, all sides of the triangular prism, as well as the joints between adjacent sides, are curved. 7
