Description

Technical Field

[0001] This utility model relates to the field of writing instrument technology, and more specifically to a writing pen with a metal clip. Background Technology

[0002] In the field of writing instruments, pen clips are a common functional component, primarily serving to allow users to easily clip the pen to clothing pockets, the edge of notebooks, or other locations, thereby improving portability. Currently, most pen products on the market use metal pen clips, which typically rely on a tight fit between the metal clip and the pen barrel to maintain the clip in a preset position—that is, through the elastic deformation of the metal clip itself or the friction between the clip and the pen barrel.

[0003] However, this method of fixing the pen solely with a tight fit has significant technical drawbacks: due to the lack of a dedicated limiting structure, the stability of the connection between the metal clip and the pen barrel depends entirely on the interference fit or surface friction during assembly. In actual use, when the clip is subjected to external force (such as accidental contact when the user picks up or puts down the pen, or friction and pressure from other objects during carrying), the tight fit structure is prone to loosening, causing the metal clip to detach from the pen barrel. This not only affects the normal use of the pen but may also cause the pen to slip and be damaged, or even pose a safety hazard. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a writing pen whose metal clip can effectively solve the problems of easy detachment and poor adaptability of the metal clip fixing method on the market that relies only on tight fit without limit. This improves the connection stability of the clip.

[0005] The technical solution of this utility model is to provide a writing pen, including a pen barrel and a pen clip. The pen barrel has a side wall with a slot for insertion. One end of the pen clip has a connector that is inserted into the slot. A limiting member is detachably connected to the pen barrel. The limiting member has a limiting part that fits into the opening of the slot and limits the position of the connector in the slot.

[0006] Compared with the prior art, the writing pen of this utility model has the following advantages: by cooperating the pen clip connector with the pen barrel connector slot, and using the limiting part on the detachable connecting limiting part to limit the connector in the connector slot, the problem of the original metal pen clip being easy to fall off due to unrestricted tight fit is effectively solved, and the stability of the connection between the pen clip and the pen barrel is improved; at the same time, the limiting part adopts a detachable connection, which is flexible in structural design, simple in processing technology, and also facilitates subsequent maintenance and replacement.

[0007] As an improvement, the limiting component includes a connecting sleeve, which is fitted inside the end of the pen barrel with its end protruding outside the end of the pen barrel; the limiting portion is located on the end of the connecting sleeve. With this structure, by fitting the connecting sleeve inside the end of the pen barrel with its end exposed and the limiting portion located on the end of the connecting sleeve, the metal pen clip can be limited by the connecting sleeve, enhancing the stability and assembly flexibility of the limiting structure.

[0008] As an improvement, the connecting sleeve has an annular rib on its side wall and a concave ring on the inner wall of the pen barrel, with the annular rib embedded in the concave ring. This structure, with the annular rib on the side wall of the connecting sleeve and the concave ring on the inner wall of the pen barrel, ensures a secure connection between the connecting sleeve and the pen barrel, preventing the connecting sleeve from loosening or falling off, and further enhancing the overall structural stability.

[0009] As an improvement, a groove is provided on one side, and the insertion slot is located at the bottom of the groove. The shape of the limiting part matches the shape of the groove, and the limiting part is embedded in the groove. With this structure, the groove on one side, the insertion slot located at the bottom of the groove, and the limiting part embedded in the groove can position the limiting part, reduce the shaking of the limiting part, make the limiting structure more compact, and improve assembly accuracy.

[0010] As an improvement, the bottom of the groove is provided with a first positioning groove, and the limiting member is provided with a positioning block, which is inserted into the first positioning groove. With this structure, after the limiting member is equipped with a positioning block and the positioning block is inserted into the first positioning groove, the displacement of the limiting member can be further restricted, the connection stability of the limiting member can be enhanced, and the limiting member can be prevented from shifting during use.

[0011] As an improvement, the pen clip has hooks on both sides of its upper end, with the hooks facing each other to form the connector. The opening of the connector slot faces upward, and there are clearance slots on both sides, which are connected to the connector slot. The bent part of the hook is embedded in the connector slot, and the vertical part of the hook is embedded in the clearance slot. With this structure, the connection between the pen clip and the connector is more secure. The bent part and the vertical part of the hook are embedded in the connector slot and the clearance slot respectively, which can restrict the multi-directional movement of the pen clip and improve the pen clip's fixing effect.

[0012] As an improvement, the limiting member is provided with second positioning grooves on both sides near the insertion groove, and the top of the hook is embedded in the corresponding second positioning groove. With this structure, the hook can be accurately positioned, preventing the hook from wobbling in the insertion groove, and further enhancing the stability of the fit between the pen clip and the limiting member.

[0013] As an improvement, the pen clip is made of wound metal. This structure utilizes the toughness and strength of the metal to ensure the structural stability and lifespan of the pen clip, while the winding process facilitates forming and simplifies the manufacturing process.

[0014] As an improvement, the detachable upper connection includes decorative elements. This structure facilitates the replacement and removal of the decorative elements, allowing the product to be customized with different elements to enhance its appearance and personalization.

[0015] As an improvement, a connecting post is provided on the upper part, and a fitting slot is provided on the decorative part to match the connecting post. The decorative part is then fitted onto the connecting post. This structure ensures a stable connection between the decorative part and the upper part, simplifies assembly, and guarantees the stability of the decorative part after installation, preventing it from easily falling off.

[0027] like Figures 1 to 7 As shown, this utility model discloses a writing pen, including a pen barrel 1, a pen clip 2, and a decorative part 3.

[0028] The pen barrel 1 has a connecting portion 101 on its side wall, and a groove 102 on its upper side. A insertion groove 103 is located at the bottom of the groove 102. One end of the pen clip 2 has a connector that inserts into the insertion groove 103. A limiting member 4 is detachably connected to the pen barrel 1. The limiting member 4 includes a connecting sleeve 401, which is fitted inside the end of the pen barrel 1, with its end protruding outside the end of the pen barrel 1. A limiting portion 402 is located on the end of the connecting sleeve 401. The shape of the limiting portion 402 matches the shape of the groove 102, and the limiting portion 402 is embedded within the groove 102, thus limiting the position of the connector within the insertion groove 103. By engaging the pen clip 2 connector with the connector slot 103 of the connecting part 101, and combining the limiting part 402 of the detachable limiting part 4 embedded in the groove 102 to limit the connector, the pen clip 2 is securely fixed, solving the problem of the original tight fit being unrestricted and easy to fall off. Furthermore, because the limiting part 4 adopts the connecting sleeve 401 structure and the end is exposed, it is convenient for the setting, assembly and maintenance of the limiting part 402.

[0029] The connecting sleeve 401 has an annular rib 403 on its side wall, and the pen barrel 1 has a concave ring 104 on its inner wall, with the annular rib 403 embedded in the concave ring 104. The groove 102 has a first positioning groove 105 at its bottom, and the limiting member 4 has a positioning block 404, which is inserted into the first positioning groove 105. The annular rib 403 on the side wall of the connecting sleeve 401 is embedded in the concave ring 104 on the inner wall of the pen barrel 1, enhancing the connection between the connecting sleeve 401 and the pen barrel 1 and preventing the connecting sleeve 401 from loosening. The first positioning groove 105 at the bottom of the groove 102 cooperates with the positioning block 404 of the limiting member 4, further restricting the displacement of the limiting member 4, improving the installation accuracy and stability of the limiting member 4, and ensuring reliable positioning of the connector.

[0030] The pen clip 2 is made of wound metal. Hooks 201 are provided on both sides of the upper end of the pen clip 2, and the hooks 201 on both sides are arranged opposite each other, forming the insertion member. Clearance grooves 106 are provided on both sides of the connecting part 101, and the clearance grooves 106 are connected to the insertion groove 103; the bent part of the hook 201 is embedded in the insertion groove 103, and the vertical part of the hook 201 is embedded in the clearance groove 106. The limiting member 4 has second positioning grooves 405 on both sides near the insertion groove 103, and the top of the hook 201 is embedded in the corresponding second positioning groove 405. The pen clip 2 is made of metal winding. The toughness and strength of the metal ensure the structural stability and service life of the pen clip 2, and the winding process is easy to form. The two sides of the pen clip 2 form a plug-in part with the hook 201 opposite each other. The bent part and the vertical part are respectively embedded in the plug-in groove 103 and the clearance groove 106, which restricts the multi-directional movement of the pen clip 2. The second positioning groove 405 of the limiting part 4 is embedded in the top of the hook 201, which further accurately positions the pen clip 2 and greatly reduces the risk of the pen clip 2 falling off.

[0031] A decorative piece 3 is detachably connected to the connecting part 101. The connecting part 101 has a connecting post 107, and the decorative piece 3 has a fitting slot that matches the connecting post 107. The fitting slot is a through hole 301, the shape of which matches the shape of the connecting post 107. The decorative piece 3 is fitted onto the connecting post 107. The size of the decorative piece 3 is larger than the assembled size of the connecting part 101 and the limiting part 402, and the decorative piece 3 can conceal the connecting part 101 and the limiting part 402. The connecting part 101 and the decorative piece 3 are detachably connected, and a stable assembly is achieved through the cooperation of the connecting post 107 and the through hole 301, facilitating the replacement and maintenance of the decorative piece 3 and meeting personalized appearance requirements. The larger size of the decorative piece 3 compared to the assembled size of the connecting part 101 and the limiting part 402 effectively conceals the internal structure, improving the overall aesthetics of the writing pen.

[0032] In assembling the writing pen of this utility model, firstly, the bent part of the hook 201 of the pen clip 2 is inserted into the insertion groove 103 of the connecting part 101, and the vertical part is inserted into the connected clearance groove 106; then, the connecting sleeve 401 is fitted onto the end of the pen barrel 1. During the fitting process, the positioning block 404 of the limiting member 4 is inserted into the first positioning groove 105 at the bottom of the groove 102, so that the limiting part 402 is embedded into the groove 102, and the top of the hook 201 is embedded into the second positioning groove 405 of the limiting member 4. At the same time, the annular rib 403 on the side wall of the connecting sleeve 401 is embedded into the concave ring 104 on the inner wall of the pen barrel 1; finally, the decorative part 3 is fitted onto the connecting post 107 of the connecting part 101 through the through hole 301 to complete the overall assembly.

[0033] The writing pen of this utility model effectively solves the problem of easy detachment of traditional metal pen clip 2 by means of multiple limiting structures (such as the limiting part 402 limiting the plug-in part, the cooperation between hook 201 and plug-in groove 103 / clearance groove 106, and the plugging of positioning block 404 and positioning groove, etc.), and greatly improves the stability of pen clip 2 connection; the metal-wound pen clip 2 has both toughness and strength, extends service life and is easy to process; the decorative part 3 has a detachable design and a covering function, which not only meets the needs of personalized appearance, but also improves the overall aesthetics of the product. At the same time, the assembly method of each component is simple and easy to maintain and replace.
