Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of push-type pens, in particular to a push-type pen. Background Art
[0002] The shell of the existing push-type ballpoint pen is basically made of plastic, but plastic is formed by processing petroleum and has a strong dependence on fossil raw materials, and the utilization rate of fossil raw materials is increasing.
[0003] A new bamboo ballpoint pen is provided, which includes a pen holder, a storage slot and a fixed rod. A storage slot is provided inside the left side of the pen holder, a fixed rod is provided inside the upper side of the storage slot, a connecting block is provided on the fixed rod, a connecting rod is provided at the lower end of the connecting block, a needle is provided at the lower end of the connecting rod, protective blocks are provided on the front and rear sides of the storage slot corresponding to the needle, and a ruler is provided on the upper side of the left end of the pen holder. When the ballpoint pen is used, the protective blocks on both sides are first rotated outward, and then the connecting rod is pushed to drive the connecting block to rotate on the fixed rod, and the needle is turned out, so that the ballpoint pen can be used as a compass. The ruler can measure the length, and the protective pad plays an anti-skid role. Setting the material of the pen holder to bamboo plays an environmental protection role. Since the ballpoint pen is not a push-type ballpoint pen, when bamboo is used as the pen holder, the use requirements of the ballpoint pen are met. If the ballpoint pen is set as a push-type ballpoint pen, a pressing head body needs to be provided on the inner cylinder of the bamboo pen holder, and a thread is provided at the connection part between the pen holder and the pen tip.
[0004] If threads and a tap body are made on a bamboo pen holder, the inner tube and outer wall of the bamboo need to be carved. When carving the inner tube of the bamboo, the carving technology is relatively complicated, which increases the difficulty of making a bamboo ballpoint pen. Moreover, if a tap body and threads are made on a bamboo pen holder, the tap body will be worn when the push-type ballpoint pen is pressed, and the bamboo pen holder is easily damaged, resulting in a shortened normal service life of the ballpoint pen. Utility Model Content
[0005] The utility model aims to provide a press-type pen which reduces the use of fossil raw materials and reduces the manufacturing process.
[0006] In order to achieve the above-mentioned purpose, the utility model provides a push-type pen, including: a pen body, a pen core, a pressing mechanism, a pressing mechanism, a core-ejecting mechanism and an elastic component; the pen body is provided with an inner cavity, the pen core is arranged in the inner cavity, the pen core abuts against the pressing mechanism, and the pressing mechanism is connected to the pressing mechanism; the pen body is connected to the core-ejecting mechanism at one end away from the pressing mechanism; the first end of the elastic component abuts against the pen core, and the second end of the elastic component abuts against the core-ejecting mechanism; the pen body includes a plastic inner shell and a bamboo outer shell, and the bamboo outer shell is sleeved on the radial outer side of the plastic inner shell; in the pressing direction, the length of the plastic inner shell is smaller than the length of the bamboo outer shell.
[0007] As can be seen from the above scheme, by providing a plastic inner shell and providing a threaded structure on the plastic inner shell, since the plastic inner shell is formed by injection molding, the threaded structure can be formed while forming the plastic inner shell, so that the push-type pen does not need to be engraved on the bamboo outer shell during production, reducing the difficulty of production and increasing the yield and success rate of the push-type pen. In addition, the length of the plastic inner shell is less than the length of the bamboo outer shell, that is, while reducing the use of fossil raw materials, the utility model can simultaneously take advantage of the characteristics of plastic and the toughness of bamboo, and can process small structural parts on the plastic inner shell, so that the push-type pen does not wear out the bamboo pen holder when it is active, thereby increasing the service life of the push-type pen.
[0008] In a further embodiment, the thickness of the plastic inner shell ranges from 0.5 mm to 1.0 mm.
[0009] It can be seen that the pen holder can be supported by the bamboo outer shell, which can reduce the thickness of the plastic inner shell and thus reduce the use of fossil raw materials.
[0010] In a further solution, an annular protrusion is provided at one end of the plastic inner shell away from the pressing mechanism, and the annular protrusion abuts against the bamboo outer shell.
[0011] It can be seen that when the plastic inner shell is arranged inside the bamboo outer shell, the annular protrusion can be used for positioning to prevent the plastic outer shell from being embedded too deeply into the bamboo outer shell.
[0012] In a further solution, the pressing mechanism includes a rotating cam and a pressing component, the pressing component includes saw teeth, and the saw teeth abut against the first protrusion of the rotating cam.
[0013] It can be seen that when the pen core does not protrude from the core mechanism, the saw teeth abut against the rotating cam. The pressing mechanism enables the pen core to achieve pressing activity through the rotating cam and the pressing member.
[0014] In a further solution, a plurality of pressing bodies protruding from the inner cavity surface are arranged at one end of the plastic inner shell close to the pressing mechanism, slots are formed between the pressing bodies, and the pressing mechanism moves along the pressing direction between the pressing bodies and the slots.
[0015] It can be seen that the pressing head body can abut against the rotating cam, and under the cooperation of the pressing head body, the slot and the pressing head mechanism, the pen core can realize the pressing activity.
[0016] In a further solution, a first protrusion is provided at the first end of the pressing head component, a thread is provided on the outer surface of the second end of the pressing head component, and the pressing mechanism is threadedly connected to the pressing head component.
[0017] It can be seen that the pressing mechanism is threadedly connected to the pressing head component so that the pressing mechanism does not fall off when pressing.
[0018] In a further solution, along the pressing direction, the thread structure of the plastic inner shell is arranged below the annular protrusion.
[0019] It can be seen that the annular protrusion has a positioning function, so that the thread structure is exposed on the surface of the bamboo outer shell so that the core-outlet mechanism is connected to the thread structure of the plastic inner shell.
[0020] In a further solution, the push-type pen is further provided with a pen clip, and the pen clip is sleeved on the bamboo shell.
[0021] This shows that the pen clip can play a clamping role.
[0022] In a further embodiment, the thickness of the bamboo shell ranges from 1.0 mm to 2.0 mm.
[0023] It can be seen that by increasing the thickness of the bamboo shell, the bamboo shell can play a supporting role. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments. DETAILED DESCRIPTION
[0031] See also Figure 1 and Figure 2The push-type pen of the utility model comprises a pen holder 1, a pen core 22, a pressing mechanism 4, a pressing mechanism, a core ejection mechanism 2 and an elastic component 21. The pen holder 1 comprises a bamboo outer shell 11 and a plastic inner shell 12, wherein the bamboo outer shell 11 is sleeved on the radial outer side of the plastic inner shell 12, and the plastic inner shell 12 and the bamboo outer shell 11 are adhered by an adhesive. The plastic inner shell 12 is hollow, and the inner cavity 125 of the plastic inner shell 12 is the inner cavity of the pen holder 1. In the pressing direction, the length of the plastic inner shell 12 is less than the length of the bamboo outer shell 11. The thickness of the plastic inner shell 12 ranges from 0.5 mm to 1.0 mm, wherein the pen holder 1 plays a supporting role through the bamboo outer shell 11, so that the thickness of the plastic inner shell 12 can be reduced, thereby reducing the use of fossil raw materials.
[0032] The thickness of the plastic pen holder of an existing ordinary ballpoint pen is about 1.5mm to 2.1mm, which can play a supporting role. In this embodiment, the thickness of the plastic inner shell 12 is reduced. The thickness of the plastic inner shell 12 of the utility model is in the range of 0.5mm to 1.0mm, which reduces the use of fossil raw materials. Among them, the thickness of the bamboo outer shell is in the range of 1.0mm to 2.0mm. Through the combination of the plastic inner shell 12 and the bamboo outer shell 11, while reducing the use of fossil raw materials, the support function of the push-type pen is not affected.
[0033] The pen core 22 is disposed in the inner cavity 125, and the pen core 22 abuts against the pressing mechanism. Figure 3 The pressing mechanism includes a rotating cam 42 and a pressing member 41. The pressing member 41 moves along the pressing direction of the pressing pen, and the rotating cam 42 rotates along the circumference of the rotating cam 42. The rotating cam 42 is provided with a first protrusion 422. The pressing member 42 includes a sawtooth 412. The first protrusion 422 is arranged in a sawtooth shape at one end close to the pressing member 41, matching the sawtooth of the pressing member 41. The sawtooth 412 of the pressing member 41 abuts against the first protrusion 422 of the rotating cam 42.
[0034] See also Figure 4 and Figure 5 The plastic inner shell 12 is provided with a plurality of pressing bodies 121 protruding from the inner cavity surface at one end close to the pressing mechanism, and a slot 122 is formed between the plurality of pressing bodies 121. The pressing mechanism moves along the pressing direction in the pressing bodies 121 and the slot 122. The second protrusion 411 on the pressing member 41 moves along the pressing direction in the slot 122. When receiving a downward pressure, the pressing member 41 drives the rotating cam 42 to press downward. After the first protrusion 422 on the rotating cam 42 contacts the tip of the pressing body 121, the first protrusion 422 of the rotating cam 42 rotates in the circumferential direction and abuts against the pressing body 121 due to the elastic force of the elastic component 21. When receiving a downward pressure again, the first protrusion 422 rotates in the circumferential direction, so that the first protrusion 422 is set in the slot 122 and abuts against the pressing member 41.
[0035] The first end of the pressing member 41 is provided with saw teeth 411, the outer surface of the second end of the pressing member 41 is provided with a second thread structure 413, and the pressing mechanism 4 is threadedly connected with the pressing member through the second thread structure 413. The user can apply pressure to the pressing pen of this embodiment through the pressing mechanism 4.
[0036] The first end of the elastic component 21 abuts against the refill 22, and the second end of the elastic component 21 abuts against the refill mechanism 2. The elastic component 21 releases elastic force, so that the refill 22 and the pressing mechanism can be tightly connected, and when pressed, the rotating cam 42 can perform a rotating operation.
[0037] The plastic inner shell 12 is provided with a first thread structure 124, and the plastic inner shell 12 is connected to the core-ejecting mechanism 2. Among them, an annular protrusion 122 is provided at one end of the plastic inner shell 12 away from the pressing mechanism, and along the pressing direction, the first end of the annular protrusion 122 abuts against the bamboo outer shell 11, and the first thread structure 123 is provided at the second end of the annular protrusion 122. After the core-ejecting mechanism 2 is connected to the first thread structure 123, it abuts against the second end of the annular protrusion 122. When the plastic inner shell 12 is set inside the bamboo outer shell 11, it can be positioned by the annular protrusion 122 to prevent the plastic outer shell 12 from being embedded too deeply in the bamboo outer shell 11.
[0038] The push-type pen is also provided with a pen clip, and the pen clip 3 is sleeved on the bamboo shell 11 , and the push-type pen can be fixed on a book through the pen clip 3 .
[0039] By setting a plastic inner shell 12, a first thread structure 123 and a press head body 122 are set on the plastic inner shell 12. Since the plastic inner shell is formed by injection molding, the thread structure 123 and the press head body 122 can be formed while forming the plastic inner shell, so that the bamboo outer shell 11 does not need to be carved during the production of the push-type pen, which reduces the production difficulty and increases the yield rate and success rate of the production.
[0040] The utility model can take advantage of the characteristics of plastic production and the toughness of bamboo, and can process small structural parts on the pen holder 1, so that the bamboo pen holder 11 will not be damaged when the push-type pen is in use, thereby increasing the service life of the push-type pen.
[0041] The above are only preferred embodiments of the present invention, but the design concept of the present invention is not limited thereto. Without departing from the concept of the present invention, more other equivalent embodiments may be included. It is possible for those skilled in the art to make various obvious changes, readjustments and substitutions without departing from the protection scope of the present invention.
