Description

Technical Field

[0001] This utility model relates to the field of office supplies technology, and more specifically, to a pen. Background Technology

[0002] A pen is an office supply used for writing. To facilitate carrying the pen, in the existing technology, a pen clip is set on the outer wall of the upper part of the pen body. Currently, there are two main ways to connect the pen clip and the pen body: (1) The pen clip and the pen body are two independent parts. The upper end of the pen clip is fastened to the outer wall of the pen body by a snap or buckle. That is, the pen clip and the pen body need to be manufactured and assembled independently, which has the disadvantages of high production cost and complex structure; (2) The pen clip is integrally injection molded on the outer wall of the pen body. That is, the upper end of the pen clip is connected to the pen body by injection molding. However, due to the characteristics of injection molded parts, the connection between the upper end of the pen clip and the pen body is prone to breakage during repeated clamping of the pen clip with the edge of the paper or the opening of the bag, which will cause the pen clamping function to fail. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a pen that has the advantages of high connection strength between the pen clip and the pen body and good anti-breakage effect, so as to ensure the stability of the pen's clamping function, and also has the advantage of simple structure.

[0004] This utility model provides a pen, including a cylindrical pen body made of metal or alloy material. A U-shaped through hole with an upward opening is provided on the upper side wall of the pen body. A pen clip is formed inside the through hole. The lower end of the pen clip is a free end. The upper end of the pen clip is connected to the pen body by a connecting part.

[0005] By adopting the above-mentioned structure, this utility model has the advantages of high connection strength between the pen clip and the pen body and good anti-breakage effect, since the pen body is made of metal or alloy material and the "U"-shaped through hole for engaging with the edge of paper or the opening of a bag is integrally formed on the pen body. This ensures the stability of the pen clip function. In addition, the pen clip and the pen body form an integral structure, eliminating the need to assemble the pen clip and the pen body, which has the advantage of simple structure.

[0006] In one possible implementation, the sidewall of the connecting part at the upper end of the through hole gradually slopes from bottom to top toward the side of the pen body corresponding to the through hole, and the upper end of the through hole forms a constriction. By adopting the above structure, the thickness of the connecting part can gradually increase from bottom to top under the action of the constriction. That is, when the edge of the paper or the bag opening is inserted into the through hole, the pen clip can be prevented from shaking, so that the pen clip is more stable. Moreover, under the action of the constriction, the strength of the connection between the pen clip and the pen body is higher, so that the pen clip is less likely to break relative to the pen clip.

[0007] In one possible implementation, the connecting part is bent outward to form a convex structure. The pen clip is offset from the inside to the outside along the radial direction of the pen body via the convex structure, so that the free end protrudes outward from the outer wall of the pen body. With this structural form of the connecting part, since the connecting part forms a convex structure from top to bottom, the pen clip as a whole can protrude from the inside to the outside along the radial direction of the pen body. Thus, when the edge of the paper or the bag opening is inserted into the through hole through the lower end, the inner side of the lower end of the free end of the pen clip can cooperate with the edge of the paper or the bag opening to guide it so that the edge of the paper or the bag opening can be inserted into the through hole. With this structural form of the connecting part, since the connecting part is bent outward to form a convex structure, the pen clip as a whole can protrude from the inside to the outside along the radial direction of the pen body. Thus, when the edge of the paper or the bag opening is inserted into the through hole through the lower end, the inner side of the lower end of the free end of the pen clip can cooperate with the edge of the paper or the bag opening to guide it so that the edge of the paper or the bag opening can be inserted into the through hole.

[0008] In one possible implementation, the lower end of the through hole gradually slopes upward toward the middle of the pen body to form a guide channel; by setting the guide channel, when the edge of the paper or the opening of the bag is to be inserted into the through hole, the guide channel can cooperate with the edge of the paper or the opening of the bag to guide it so that the edge of the paper or the opening of the bag can be inserted into the through hole.

[0009] In one possible implementation, the through hole above the guide channel is provided with a curved section. The curved section is an arc shape that gradually slopes towards the middle of the pen body from bottom to top and then gradually slopes towards the outside of the pen body. Protrusions are formed on both sides of the free end of the pen clip at the corresponding position of the curved section. With the setting of the curved section, after the edge of the paper or the bag opening is inserted into the through hole, the paper and the bag opening can be deformed under the action of the curved section, thereby increasing the friction between the paper or the bag opening and the pen clip and the pen body, so as to effectively prevent the pen body from detaching from the paper or the bag opening. In addition, with the above structure, the protrusions can press the deformed paper or the bag opening tightly against the rear side wall of the curved section, thereby improving the anti-detachment effect between the pen body and the paper or the bag opening. Furthermore, the structural strength at the lower end of the pen clip can also be improved under the action of the protrusions.

[0010] In one possible implementation, the pen clip has inwardly folded edges on both sides of its side edges located between the connecting part and the free end. By providing inwardly folded edges on both sides of the pen clip, the overall bending strength of the pen clip can be improved, so as to effectively prevent the pen clip from deforming and ensure that the pen clip can reliably clamp the paper or bag opening to the pen body.

[0011] In one possible implementation, the pen further includes an insert disposed on the side of the through hole facing the middle of the pen body and fixed to the pen body. The insert is used to separate the through hole and the inner cavity of the pen body. By providing the insert, since the insert can separate the through hole and the inner cavity of the pen body, dust can be prevented from entering the interior of the pen body. In addition, the insert can be made of plastic material and fixed to the inner edge of the back side of the through hole.

[0012] In one possible implementation, the pen clip has an arc-shaped cross-section, with the arc length of the pen clip accounting for 1 / 4 to 1 / 3 of the pen body's circumference. By using a pen clip of this size, the structural strength of the pen clip can be guaranteed, ensuring its resistance to deformation, thereby ensuring that the pen clip can reliably clamp paper or bag openings onto the pen body.

[0013] In one possible implementation, the width D of the through hole is 1.5-2.5 mm. By using a through hole of this width, the pen clip can reliably clamp the paper or the bag opening onto the pen body after the paper edge or the bag opening is inserted into the through hole, thereby improving the anti-detachment effect between the pen body and the paper or the bag opening.

[0014] In one possible implementation, the through hole has an axisymmetric structure with the central axis of the pen body as the axis of symmetry; the through hole extends through the pen body from left to right; by adopting this structure, when the through hole is cut, for example, when the pen body is cut with a laser to form the through hole, the laser beam can be emitted from left to right relative to the pen body, and after the laser beam travels a closed path, the through hole can be cut and formed on the pen body, which has the advantage of convenient through hole opening.

"Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0019] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] Example 1 See Figure 1-4 As shown, this application discloses a pen, including a cylindrical pen body 1 made of metal or alloy material. A U-shaped through hole 11 with an upward opening is provided on the upper side wall of the pen body 1. A pen clip 12 is formed inside the through hole 11. The lower end of the pen clip 12 forms a free end 121. The upper end of the pen clip 12 is connected to the pen body 1 by a connecting part 122.

[0021] The side wall of the upper end of the through hole 11 corresponding to the connecting part 122 gradually slopes from bottom to top towards the side of the pen body 1 corresponding to the through hole 11, and forms a constriction 13 at the upper end of the through hole 11. By adopting the above structure, the thickness of the connecting part can gradually increase from bottom to top under the action of the constriction. That is, when the edge of the paper or the bag opening is inserted into the through hole, the pen clip can be prevented from shaking, so that the pen clip is more stable. Moreover, under the action of the constriction, the strength of the connection between the pen clip and the pen body is higher, so that the pen clip is less likely to break relative to the pen clip.

[0022] The lower end of the through hole 11 gradually slopes towards the middle of the pen body 1 from bottom to top to form a guide channel 111; by setting the guide channel, when the edge of the paper or the opening of the bag is to be inserted into the through hole, the guide channel can cooperate with the edge of the paper or the opening of the bag to guide it so that the edge of the paper or the opening of the bag can be inserted into the through hole.

[0023] The through hole 11 above the guide channel 111 is provided with a curved section 112. The curved section 112 is an arc shape that gradually slopes towards the middle of the pen body 1 from bottom to top and then gradually slopes towards the outside of the pen body 1. The free end 121 of the pen clip 12 at the corresponding position of the curved section 112 forms protrusions 123 on both sides. With the setting of the curved section, after the edge of the paper or the bag opening is inserted into the through hole, the paper and the bag opening can be deformed under the action of the curved section, thereby increasing the friction between the paper or the bag opening and the pen clip and the pen body, so as to effectively prevent the pen body from detaching from the paper or the bag opening. In addition, after adopting the above structure, the protrusions can press the deformed paper or the bag opening tightly against the rear side wall of the curved section, thereby improving the anti-detachment effect between the pen body and the paper or the bag opening. Furthermore, under the action of the protrusions, the structural strength at the lower end of the pen clip can also be improved.

[0024] The pen clip 12 located between the connecting part 122 and the free end 121 has inwardly folded edges on both sides. By providing inwardly folded edges on both sides of the pen clip, the overall bending strength of the pen clip can be improved, so as to effectively prevent the pen clip from deforming and ensure that the pen clip can reliably clamp the paper or bag opening to the pen body.

[0025] See you again Figure 4 As shown, the pen also includes an insert 2. The insert 2 is disposed on the side of the through hole 11 facing the middle of the pen body 1 and is fixed to the pen body 1. The insert 2 is used to separate the through hole 11 and the inner cavity of the pen body 1. By setting the insert, since the insert can separate the through hole and the inner cavity of the pen body, dust can be prevented from entering the interior of the pen body. In addition, the insert can be made of plastic material and the insert is fixed to the inner edge of the back side of the through hole.

[0026] The pen clip 12 has an arc-shaped cross-section, and the arc length of the pen clip 12 accounts for 1 / 4 to 1 / 3 of the circumference of the pen body 1. By adopting a pen clip of this size, the structural strength of the pen clip can be guaranteed, so as to ensure the deformation resistance of the pen clip and thus ensure that the pen clip can reliably clamp the paper or bag opening to the pen body.

[0027] The width D of the through hole 11 is 1.5-2.5mm. By using a through hole of this width, the pen clip can reliably clamp the paper or the bag opening to the pen body after the paper edge or the bag opening is inserted into the through hole, thereby improving the anti-detachment effect between the pen body and the paper or the bag opening.

[0028] See you again Figure 4As shown, the through hole 11 has an axisymmetric structure with the central axis of the pen body 1 as the axis of symmetry; the through hole 11 extends through the pen body 1 from left to right; by adopting this structure, when the through hole is cut, for example, when the pen body is cut with a laser to form the through hole, the laser beam can be emitted from left to right relative to the pen body, and after the laser beam travels a closed path, the through hole can be cut and formed on the pen body, which has the advantage of convenient through hole opening.

[0029] Example 2 See Figure 5-6 As shown, unlike Embodiment 1, the connecting part 122 is bent outward to form a convex structure. The pen clip 12 is offset from the inside to the outside along the radial direction of the pen body 1 via the convex structure, so that the free end 121 protrudes outward from the outer wall of the pen body 1. By adopting this structural form of the connecting part, since the connecting part forms a convex structure from top to bottom, the pen clip as a whole can protrude from the inside to the outside of the pen body along the radial direction of the pen body. Therefore, when the edge of the paper or the bag opening is inserted into the through hole through the lower end, the free end of the pen clip... The inner side of the lower end can cooperate with the edge of the paper or the opening of the bag to guide it so that the edge of the paper or the opening of the bag can be inserted into the through hole; after adopting this type of connecting part, because the connecting part is bent outward to form an outward convex structure, the pen clip as a whole can protrude from the inside to the outside of the pen body in the radial direction of the pen body. Thus, in the process of the edge of the paper or the opening of the bag being inserted into the through hole through the lower end, the inner side of the lower end of the free end of the pen clip can cooperate with the edge of the paper or the opening of the bag to guide it so that the edge of the paper or the opening of the bag can be inserted into the through hole.

[0030] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
