[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] See also Figures 1 to 4 In an embodiment of the present invention, a PVC-based wood-plastic environmentally friendly pencil includes a pen body composed of a plurality of splicing sections 1 and a pencil lead 2. The splicing section 1 includes a tapered barrel 101, a polygonal shell 102, an inner support column 103, a 7-shaped slot 104, and a 7-shaped block 105.
[0026] The polygonal shell 102 is fixed to the top of the conical cylinder 101, the inner support column 103 is fixed to the inner bottom of the conical cylinder 101, the 7-shaped slot 104 is opened at the inner bottom of the polygonal shell 102 and passes through the top of the conical cylinder 101 to the outside of the conical cylinder 101, and the 7-shaped block 105 is fixed to the inner top of the polygonal shell 102 and extends above the polygonal shell 102;
[0027] The inner support cylinder 103 is sleeved on the outer side of the pencil lead 2, and the multiple polygonal shells 102 in the vertically distributed multiple splicing sections 1 are sequentially fitted, and the multiple tapered cylinders 101 are sleeved on each other to achieve wrapping and support of the pencil lead 2;
[0028] The 7-shaped clamping block 105 is clamped into the 7-shaped clamping groove 104 on another splicing section 1 to achieve the connection and fixation of the two splicing sections 1.
[0029] In this embodiment: It should be noted that: in the initial state of this environmentally friendly pencil leaving the factory, the front end of the pencil lead 2 protrudes outside the bottom joint 1, and the end of the pencil lead 2 has been polished and can be used directly for writing;
[0030] When the pencil lead 2 is worn close to the bottom end of the tapered barrel 101 of the bottom joint 1, the bottom joint 1 can be removed. The operation steps are as follows:
[0031] Pinch the bottom joint 1 with one hand, pinch the second joint 1 with the other hand and apply opposite pulling force. At this time, the 7-shaped card block 105 on the bottom joint 1 and the second joint 1 squeeze each other. The 7-shaped card block 105 is deformed by the force, and the top horizontal part of the 7-shaped card block 105 is separated from the top horizontal groove part of the 7-shaped card groove 104 on the second joint 1. Finally, the 7-shaped card block 105 is pulled out from the inside of the 7-shaped card groove 104. That is, the bottom joint 1 is separated from the second joint 1. At this time, the length of the pencil lead 2 protruding from the tapered tube 101 is increased, and then writing operation can be carried out again.
[0032] Repeating the above operation can achieve continuous use of the pencil. Compared with the traditional PVC-based wood-plastic environmentally friendly pencil sharpening operation using a pencil sharpener, it can effectively avoid the situation where debris adheres to the hands due to the sharpening operation, thereby improving the safety of the PVC-based wood-plastic environmentally friendly pencil. The overall operation is convenient and more easy to use.
[0033] Please refer to Figures 1 to 4 The inner diameter of the inner support cylinder 103 matches the outer diameter of the pencil lead 2. Between two adjacent splicing sections 1, the bottom of the upper conical cylinder 101 fits tightly with the top of the lower inner support cylinder 103, and the outer side of the upper conical cylinder 101 fits with the inner side of the lower conical cylinder 101.
[0034] The 7-shaped slots 104 and the 7-shaped blocks 105 are distributed at the five end corners of the polygonal housing 102 . The upper and lower end surfaces of the top horizontal portion of the 7-shaped blocks 105 are in an arc structure.
[0035] In this embodiment, the structure of the plurality of splicing sections 1 spliced together can have a strong bending resistance, thereby effectively protecting the pencil lead 2 and ensuring the stable use of the pencil lead 2.
[0036] In addition, the upper and lower end surfaces of the top horizontal part of the 7-shaped card block 105 are in the form of arc surfaces, so that when the 7-shaped card block 105 is connected to and separated from the 7-shaped card slot 104, the top horizontal part of the 7-shaped card block 105 can better withstand the force and deform, thereby facilitating the disassembly of the splicing section 1 and making its operation more labor-saving.
[0037] Please refer to Figure 1 There is no 7-shaped block 105 on the inner side of the polygonal shell 102 in the topmost splicing section 1, and a polygonal top cover 3 is bonded and fixed to the top of the polygonal shell 102, and the polygonal top cover 3 is bonded and fixed to the top of the pencil lead 2.
[0038] In this embodiment, it should be additionally explained that the multiple splicing sections 1 near the polygonal top cover 3 can be glued and fixed between the inner support cylinder 103 and the pencil lead 2 to ensure that the pencil lead 2 does not fall off, and the splicing length of the multiple splicing sections 1 glued to the pencil lead 2 is the final gripping length.
[0039] Please refer to Figures 1 to 4 The conical cylinder 101, the polygonal shell 102, the inner support cylinder 103, the 7-shaped slot 104, and the 7-shaped block 105 are integrally formed by an injection molding process.
[0040] In this embodiment, the splicing section 1 is integrally formed by an injection molding process, and then the splicing sections 1 need to be spliced in sequence to install the pencil length. The overall production and assembly process is simple and easy to promote and use.
[0041] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
