[0001] The utility model relates to the technical field of wood-plastic environmentally friendly pencils, in particular to a wood-plastic environmentally friendly pencil. Background Art

[0002] Wood-plastic pencils are made from wood and plastic through a specific processing technique. These pencils combine the advantages of both wood and plastic, such as being lightweight, durable, and resistant to breaking. They also effectively reduce wood consumption, contributing to a positive environmental impact. During the production process, the pencil leads come in various sizes (0.3, 0.5, 0.7, and 0.9 mm). The barrels are manufactured based on these lead specifications, meaning each barrel size corresponds to a specific lead size. To ensure that a single barrel size can accommodate multiple lead sizes, a new environmentally friendly wood-plastic pencil is available. Utility Model Content

[0003] The utility model aims to provide a wood-plastic environmentally friendly pencil in order to realize the purpose that a pen holder of one specification can adapt to pencil leads of various specifications.

[0004] To achieve the above-mentioned object, the utility model provides the following technical solutions: a wood-plastic environmentally friendly pencil, comprising a pencil lead and a penholder assembly, wherein two penholder assemblies are spliced together to wrap and fix the pencil lead, and the penholder assembly comprises a penholder half sleeve, a lead mounting arc groove, an extrusion trapezoidal block, a limit slot, an L-shaped extrusion groove, and a docking plug block;

[0005] The refill installation arc groove is provided at the center of the lower surface of the pen barrel half sleeve, the extruded trapezoidal block is fixed to the lower surface of the pen barrel half sleeve and is distributed on one side of the refill installation arc groove, and the limiting slot is provided on the lower surface of the refill installation arc groove and is distributed on the side of the extruded trapezoidal block away from the refill installation arc groove;

[0006] The L-shaped extrusion groove is formed on the lower surface of the refill installation arc groove and is distributed on the side of the pen half sleeve away from the extrusion trapezoidal block. The pen half sleeve is formed with an arc-shaped pressing block through the L-shaped extrusion groove. The docking block is fixed to the lower surface of the pen half sleeve and is located on the side of the L-shaped extrusion groove away from the refill installation arc groove.

[0007] When two sets of pen barrel assemblies symmetrically distributed up and down are spliced together, the extrusion trapezoidal block on one pen barrel half sleeve is inserted into the inner side of the L-shaped extrusion groove on the other pen barrel half sleeve, and the limiting slot on one pen barrel half sleeve is sleeved on the outer side of the docking block on the other pen barrel half sleeve to realize the docking operation of the two pen barrel half sleeves. The two pen barrel half sleeves wrap and fix the pencil lead through two lead mounting arc grooves and two arc-shaped pressure blocks.

[0008] As a further solution of the present invention: the extruded trapezoidal block is inclined toward the side of the refill installation arc groove, and the width of the extruded trapezoidal block increases from top to bottom, and the maximum width of the top of the extruded trapezoidal block is greater than the top width of the L-shaped extrusion groove.

[0009] As a further solution of the present invention: the outer wall width of the docking block matches the inner wall width of the limiting slot, and the inner wall diameter of the lead installation arc groove matches the maximum specification diameter of the pencil lead.

[0010] As a further solution of the present invention: horizontal straight surfaces are symmetrically formed on both sides of the outer wall of the pen barrel half sleeve, and an identification groove is opened at the bottom edge of the horizontal straight surface. After the two pen barrel half sleeves are spliced together, different specifications of pencil leads are marked by filling the identification groove area with different colors of paint.

[0011] As a further solution of the present invention: the pen barrel half sleeve, the pen core mounting arc groove, the extruded trapezoidal block, the limit card slot, the L-shaped extrusion groove, the arc pressure block, the docking plug block, the horizontal straight surface, and the marking groove are integrally formed by extrusion injection molding or molding technology.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] By arranging the pen barrel assembly, when the two pen barrel halves wrap and fix the pencil lead, when the trapezoidal extrusion block is inserted into the inner side of the L-shaped extrusion groove, the inclined surface of the trapezoidal extrusion block contacts the arc-shaped pressing block. As the trapezoidal extrusion block moves downward, the arc-shaped pressing block is deformed toward the inner side of the pen lead installation arc groove under force. In this way, by coordinating the change in the distance between the two pen lead installation arc grooves when they approach each other, pencil leads of different diameters can be wrapped and fixed. Then, pencil leads of various specifications can be fixed through a pen barrel assembly of one specification, so that the overall processing technology of the wood-plastic environmentally friendly pencil is optimized and cost control can be better achieved.

[0018] 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.

[0019] See also Figures 1 to 3 In an embodiment of the utility model, a wood-plastic environmentally friendly pencil includes a pencil lead 1 and a pen body assembly 2. Two pen body assemblies 2 are spliced together to wrap and fix the pencil lead 1. The pen body assembly 2 includes a pen body half sleeve 201, a pen lead mounting arc groove 202, an extrusion trapezoidal block 203, a limiting card slot 204, an L-shaped extrusion groove 205, and a docking plug block 207.

[0020] The refill installation arc groove 202 is provided at the center of the lower surface of the pen barrel half sleeve 201. The extrusion trapezoidal block 203 is fixed to the lower surface of the pen barrel half sleeve 201 and is located on one side of the refill installation arc groove 202. The limiting slot 204 is provided on the lower surface of the refill installation arc groove 202 and is located on the side of the extrusion trapezoidal block 203 away from the refill installation arc groove 202.

[0021] An L-shaped extrusion groove 205 is formed on the lower surface of the refill installation arc groove 202 and is located on the side of the pen half sleeve 201 away from the extrusion trapezoidal block 203. The pen half sleeve 201 is formed with an arc-shaped pressing block 206 through the L-shaped extrusion groove 205. A docking block 207 is fixed to the lower surface of the pen half sleeve 201 and is located on the side of the L-shaped extrusion groove 205 away from the refill installation arc groove 202.

[0022] When the two symmetrically distributed penholder assemblies 2 are connected to each other, the extrusion trapezoidal block 203 on one penholder half sleeve 201 is inserted into the inner side of the L-shaped extrusion groove 205 on the other penholder half sleeve 201, and the limiting groove 204 on one penholder half sleeve 201 is sleeved onto the outer side of the docking plug 207 on the other penholder half sleeve 201, thereby achieving the docking operation of the two penholder half sleeves 201. The two penholder half sleeves 201 wrap and fix the pencil lead 1 through the two lead installation arc grooves 202 and the two arc-shaped pressing blocks 206;

[0023] The extruded trapezoidal block 203 is inclined toward the side of the refill mounting arc groove 202, and the width of the extruded trapezoidal block 203 increases from top to bottom. The maximum width of the top of the extruded trapezoidal block 203 is greater than the top width of the L-shaped extrusion groove 205.

[0024] The outer wall width of the docking block 207 matches the inner wall width of the limiting slot 204 , and the inner wall diameter of the lead installation arc slot 202 matches the maximum specification diameter of the pencil lead 1 .

[0025] In this embodiment, when the pencil lead 1 is wrapped and fixed by the pen barrel assembly 2, the two pen barrel halves 201 are symmetrically distributed (it should be noted that the two pen barrel halves 201 are in opposite directions), so that the trapezoidal extrusion blocks 203 on the two pen barrel halves 201 are aligned with the L-shaped extrusion grooves 205, the limiting slots 204 and the docking blocks 207.

[0026] After that, the pencil lead 1 is placed inside the lead installation arc groove 202 on one of the pen barrel half sleeves 201, and then the other pen barrel half sleeve 201 is clamped thereto. The docking block 207 is engaged with the limiting clamping groove 204 to achieve docking and positioning of the two pen barrel half sleeves 201. When the trapezoidal extrusion block 203 is clamped into the inner side of the L-shaped extrusion groove 205, the inclined surface of the trapezoidal extrusion block 203 contacts the arc-shaped pressing block 206. As the trapezoidal extrusion block 203 moves downward, the arc-shaped pressing block 206 is deformed toward the inside of the lead installation arc groove 202 under force. In this way, by coordinating the change in the distance between the two lead installation arc grooves 202 when they approach each other, pencil leads 1 of different diameters can be wrapped and fixed.

[0027] Then, pencil leads 1 of various specifications can be fixed by using a penholder assembly 2 of one specification, thereby optimizing the overall processing technology of the wood-plastic environmentally friendly pencil and achieving better cost control.

[0028] It should also be noted that: since the numerical value of pencil leads 1 of different specifications and diameters varies little, after the two sets of pen body assemblies 2 are spliced together, the internal gap is small, and this gap can be filled with glue. The glue is used to bond and fix the two sets of pen body assemblies 2 and the pencil lead 1.

[0029] Please refer to Figures 1 to 3 Horizontal straight surfaces 208 are symmetrically formed on both sides of the outer wall of the pen half sleeve 201, and an identification groove 209 is opened at the bottom edge of the horizontal straight surface 208. After the two pen half sleeves 201 are spliced together, different specifications of the pencil lead 1 are marked by filling the identification groove 209 with different colors of paint.

[0030] In this embodiment, the horizontal surface 208 allows buyers to better locate the area where the marking groove 209 is located. When the pen barrel assembly 2 fixes pencil leads 1 of different diameters, the gap between the two marking grooves 209 is different (it should be noted that the marking groove 209 corresponding to the pencil lead 1 with the largest diameter has the largest gap). As a result, the thickness of the marking paint varies. Combined with the distinction of different colors, buyers can quickly determine the specifications of the pencil lead 1.

[0031] Please refer to Figures 1 to 3 The pen barrel half sleeve 201, the pen core installation arc groove 202, the extrusion trapezoidal block 203, the limiting card groove 204, the L-shaped extrusion groove 205, the arc pressure block 206, the docking block 207, the horizontal straight surface 208, and the identification groove 209 are integrally formed by extrusion injection molding or molding technology.

[0032] In this embodiment, the integrally formed penholder assembly 2 is formed by injection molding, which can effectively simplify the overall production process of the wood-plastic pencil, improve production efficiency, and control costs. Such a wood-plastic pencil is easy to promote and produce.

[0033] 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.
