Description

Technical Field

[0001] This utility model belongs to the field of everyday stationery technology and relates to a side-mounted bolt-action stationery pen. Background Technology

[0002] Push-button stationery pens often suffer from problems such as accidental activation, inconvenience of one-handed operation, and monotonous structure. To address these issues, some improved stationery pens have emerged on the market, such as stationery pens with a rotating lead-out mechanism and stationery pens with a side-press lead-out mechanism. Some stationery pens also adopt a bolt-like structure. However, these structures are usually more complex, have higher manufacturing costs, or are insufficient in terms of ease of operation and reliability. Summary of the Invention

[0003] To address the aforementioned issues, this invention provides a side-mounted bolt-action stationery pen. Through optimized structural design, it achieves advantages such as simple structure, convenient and reliable operation, easy and error-free assembly, and novel appearance, thereby improving user experience and product production efficiency.

[0004] To achieve the above objectives, this utility model designs a side-bolt-type stationery pen, which cleverly combines a specific pen barrel split structure, a precise bolt guiding and locking mechanism, and a unique assembly and positioning structure. It includes a pen barrel, a pen core set inside the pen barrel, and a pen tip set at the front end of the pen barrel. Its features include a cap buckle, a bolt pusher, and an elastic component.

[0005] The upper end of the pen barrel is provided with an L-shaped guide groove;

[0006] The cap buckle is attached to the top of the pen barrel;

[0007] The pull-bolt pusher is restricted inside the pen barrel by the cap buckle and can slide along the L-shaped guide groove, thereby pushing the pen refill to move, so that the pen tip of the pen refill can extend and lock.

[0008] The elastic component causes the pen lead to tend to move away from the pen tip.

[0009] A further solution is a side-bolt stationery pen, wherein the inner wall of the cap buckle is provided with a limiting protrusion, which cooperates with the L-shaped guide groove. In the cross-section, the inner wall of the limiting protrusion and the inner wall of the pen barrel where the L-shaped guide groove is located form a circle to limit the unique assembly angle of the cap buckle relative to the pen barrel and prevent relative rotation between the two.

[0010] The cap end has an opening that mates with the L-shaped guide groove of the pen barrel. Part of its function is to provide visual guidance. When the cap opening is aligned with the L-shaped guide groove opening, the limiting protrusion slides along the upper end of the L-shaped guide groove, making it easy to find the unique assembly angle during assembly.

[0011] The inner wall of the cap buckle has two annular buckle protrusions for engaging with the pen barrel, so that the cap buckle can be stably fixed on the pen barrel after assembly.

[0012] Furthermore, each of the aforementioned buckle protrusions has a step protruding from the inner wall of the cap, namely the first step and the second step from top to bottom. The two steps effectively press the upper opening of the pen barrel inward, thereby interacting with the pen barrel and further increasing the stability of the connection between the cap and the pen barrel.

[0013] The outer surface of the upper end of the pen barrel is a stepped conical surface, which is a step in cross-section. From top to bottom, there are three steps and four steps. The part that slides in contact with the inner wall of the cap buckle is the first guide cone surface and the second guide cone surface from top to bottom. During assembly, the second step of the inner wall of the cap buckle first slides along the first guide cone surface, passes the third step, and then slides along the second guide cone surface. At this time, the first step slides along the first guide cone surface, passes the third step, and then slides along the second guide cone surface. When the lowest buckle protrusion passes the fourth step and is pressed against it, the cap buckle is deformed due to compression. The second step will apply a compressive force to the second guide cone surface, so that the cap buckle is tightly fitted to the uppermost end of the pen barrel.

[0014] The corners and lower end of the L-shaped guide groove are rounded, and the opening of the cap buckle is also rounded, echoing each other in design language. The upper opening of the L-shaped guide groove has a chamfer, which allows the pull bolt pusher to slide smoothly on the pen barrel and facilitates the sliding of the pull bolt pusher and the inner wall limiting protrusion of the cap buckle into the upper opening of the L-shaped guide groove during assembly.

[0015] The pull-bolt pusher is a single component made of metal or plastic. The part protruding from the pen barrel is the handle for user operation, allowing the user to directly operate the stationery pen.

[0016] The above technical solutions ensure that this utility model of a side-mounted bolt-action stationery pen has a simple structure, is easy to assemble, and is somewhat fun to use. It solves the pain points of push-button ballpoint pens, gel pens, accidental touches, inconvenience of one-handed operation, monotonous structure, and some bolt-action stationery pens, such as complex structure, low reliability, or difficult assembly.

Detailed Implementation

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] Example 1.

[0029] like Figures 1 to 5 As shown, this embodiment describes a side-bolt type stationery pen, which includes a pen barrel 2, a pen core 5 disposed inside the pen barrel 2, and a pen tip 3 disposed at the front end of the pen barrel 2. It also includes a cap buckle 1, a bolt pusher 4, and an elastic component 6, which is a compression spring in the figure.

[0030] A preferred embodiment is as follows: the upper end of the pen barrel 2 is provided with an L-shaped guide groove 21; the cap buckle 1 is sleeved on the uppermost end of the pen barrel 2; the pull-bolt pusher 4 is restricted inside the pen barrel 2 by the cap buckle 1, and can slide along the L-shaped guide groove 21 to push the pen refill 5 to move, so that the pen tip of the pen refill 5 extends and locks; the compression spring 6 makes the pen refill 5 tend to move away from the pen tip 3.

[0031] like Figure 6As shown, the inner wall of the cap buckle 1 is provided with a limiting protrusion 11. The limiting protrusion 11 cooperates with the L-shaped guide groove 21. In the cross-section, the inner wall of the limiting protrusion and the inner wall of the pen barrel where the L-shaped guide groove is located form a circle to limit the unique assembly angle of the cap buckle 1 relative to the pen barrel 2 and prevent the two from rotating relative to each other.

[0032] like Figure 7 As shown, the cap buckle 1 has an opening 13 at its end that mates with the L-shaped guide groove 21 of the pen barrel 2. Part of its function is to provide visual guidance. When the opening of the cap buckle 1 is aligned with the opening of the L-shaped guide groove 21, the limiting protrusion 11 slides along the upper end of the L-shaped guide groove 21, making it easier to find the unique assembly angle during assembly.

[0033] Figure 8 This is a schematic diagram illustrating the assembly process of the cap 1 and the pen barrel 2. The cap 1 has two annular snap-fit ​​protrusions 12 on its inner wall. Below each snap-fit ​​protrusion 12 is a step protruding from the inner wall of the cap 1, which, from top to bottom, are the first step 121 and the second step 122. The upper outer surface of the pen barrel 2 is a stepped conical surface, forming steps in its cross-section, which, from top to bottom, are the third step 211 and the fourth step 212. The parts that slide in contact with the inner wall of the cap 1, from top to bottom, are the first guide cone surface 22 and the second guide cone surface 23. During assembly, the second step 122 on the inner wall of the cap buckle 1 first slides along the first guide cone surface 22, and after passing the third step 211, it slides along the second guide cone surface 23. At this time, the first step 121 slides along the first guide cone surface 22, passes the third step 211, and then slides along the second guide cone surface 23. When the lowest buckle protrusion 12 passes the fourth step 212 and is pressed against it, the cap buckle 1 is deformed due to compression. The second step 121 will apply a compressive force to the second guide cone surface 23, so that the cap buckle 1 is tightly fitted to the uppermost end of the pen barrel 2.

[0034] like Figure 2 As shown, the corners and lower end of the L-shaped guide groove 21 are rounded, allowing the pull-bolt pusher 4 to slide smoothly on the pen barrel 2. The opening 13 is also rounded, echoing the design language and enhancing the aesthetic appeal. The upper opening of the L-shaped guide groove 21 has a chamfered corner 24, facilitating the sliding of the pull-bolt pusher 4 and the inner wall limiting protrusion 11 of the cap buckle 1 into the upper opening of the L-shaped guide groove 21 during assembly.

[0035] like Figure 9 As shown, the pull-bolt pusher 4 is a single component made of metal or plastic. The part protruding from the pen barrel 2 is the handle 41 for user operation, which is designed to allow the user to directly operate the stationery pen. It is spherical to optimize the user's feel.
