Description

Technical Field

[0001] This utility model relates to the field of stationery, specifically to a ballpoint pen with a convenient refill. Background Technology

[0002] A ballpoint pen is a pen that uses a ball at the tip of the pen or refill to roll and dispense the writing medium; a ballpoint pen is a type of pen that uses a tiny rotating ball made of brass, steel or tungsten carbide to release ink onto the paper when writing; ballpoint pens are very different from their predecessors—reed pens, quill pens, pens with metal nibs and fountain pens.

[0003] The existing technology has the following problems:

[0004] In existing technologies, the pressing mechanism usually uses a spring. Therefore, when disassembling and replacing the pen refill, the spring needs to be removed, which is a relatively troublesome operation. At the same time, the spring is easy to fall off and be lost, affecting its use. Therefore, it is necessary to design a ballpoint pen that makes it easy to replace the pen refill. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a ballpoint pen with easy refill replacement to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A ballpoint pen with easy-to-replace refill includes a pen barrel, a locking assembly provided on the inner wall of the pen barrel, a pen refill provided on the inner wall of the pen barrel, a protective top assembly provided on the top of the pen barrel, and an anti-slip strip assembly attached to the outer wall of the pen barrel. The pen barrel includes an upper main body and a lower conical connector, and the main body and the conical connector are threaded together. The connection between the main body and the conical connector is located at the bottom of the anti-slip strip assembly.

[0008] The locking assembly includes a limiting groove formed on the outer wall of the pen holder and a spring bracket fixedly connected to the inner wall of the pen holder. The inner wall of the spring bracket is fitted with a pen refill return spring, and the limiting groove is fitted with a locking mechanism.

[0009] The locking mechanism includes a slide block that is movably fitted into the inner wall of a limiting groove. A locking spring is fixedly connected to the slide block. A connecting plate is fixedly connected to one end of the locking spring. A plug rod is fixedly connected to one side of the connecting plate, and a pull rod is fixedly connected to the side of the connecting plate away from the plug rod. With this locking assembly, when the pen refill needs to be replaced, the conical connector is rotated to open the pen barrel. The pull rod is pulled to both sides, and under the action of the locking spring, the connecting plate slides outward, causing the plug rod to move away from the annular groove on the outer wall of the pen refill, thus releasing the limitation on the pen refill. The pen refill is then pulled out, and a new pen refill is inserted. Under the action of the locking spring, the plug rod returns to its original position and is inserted into the annular groove, completing the limitation on the pen refill. Together with the pen refill return spring, this mechanism works in conjunction with a button for pressing and controlling the button's position.

[0010] By replacing the traditional protrusions on both sides of the pen refill with a locking mechanism and an annular groove on the pen refill, the problem of having to remove the reset spring when replacing the pen refill with a transmission mechanism is solved.

[0011] The protective top assembly includes a side connecting seat fixedly mounted on the top of the pen holder. A protective frame is movably connected to the inner wall of the side connecting seat, and a stop rod is fixedly connected to the outer wall of one end of the protective frame. With the setting of the protective top assembly, in use, firstly, after the pen refill is pressed out, the protective frame is flipped so that the stop rod is perpendicular to the top and contacts the pen holder. The setting of the protective frames on both sides can achieve the effect of protecting the button, avoiding accidental button touch that would cause the pen refill reset spring to retract the pen refill, thus affecting the user experience.

[0012] The anti-slip strip assembly includes a rubber anti-slip strip, one side of which is fixedly connected with double-sided adhesive, and the side of the rubber anti-slip strip away from the double-sided adhesive is provided with a rib. By setting up the anti-slip strip assembly, the traditional specific rubber anti-slip sleeve can be replaced. When it wears out or sheds, the anti-slip strip assembly can be easily replaced. Similar to replacing the grip tape on a badminton racket, the old anti-slip strip assembly is removed and attached to the pen holder with double-sided adhesive. The rubber anti-slip strip is then wrapped around the pen holder along the rib, and finally sealed with double-sided adhesive at the end.

[0013] Preferably, a short protective cylinder is fixedly connected to the outer wall of the spring bracket, and the inner wall of the short protective cylinder is in close contact with the outside of the pen refill return spring.

[0014] Preferably, the number of locking components is two, and the two locking components are arranged symmetrically.

[0015] Preferably, the outer wall of the pen refill has an annular groove, and the inner wall of the annular groove is fitted and connected to the outer wall of one end of the insertion rod.

[0016] Preferably, the inner wall of the pen holder is provided with a pressing mechanism, the bottom of which is connected to the top of the pen refill, and a button is connected to the top of the pressing mechanism.

[0017] Preferably, there are two protective top components, and the two protective top components are arranged on both sides of the button.

[0018] Preferably, there are two protective frames, and when the abutment is perpendicular to the top and contacts the pen holder, the height of the two protective frames is greater than the height of the button.

[0019] The beneficial effects of this utility model are as follows: 1. This ballpoint pen, which facilitates refill replacement, utilizes a locking component. When refill replacement is needed, rotating the conical connector opens the pen barrel, pulling the lever to both sides causes the connecting plate to slide outward under the action of the locking spring. The insert rod moves away from the annular groove on the outer wall of the pen refill, releasing the restriction on the pen refill. The pen refill is then pulled out, and a new pen refill is inserted. Under the action of the locking spring, the insert rod returns to its original position and is inserted into the annular groove, thus completing the restriction on the pen refill. Together with the pen refill reset spring, it can be used in conjunction with a button for pressing and controlling the button's position for use.

[0020] 2. This ballpoint pen with easy refill replacement features a protective top assembly. When the refill is pressed out, the protective frame flips up, causing the lever to contact the pen barrel perpendicularly to the top. The protective frames on both sides protect the button, preventing accidental button presses that could cause the refill spring to reset and retract the refill, thus improving the user experience.

[0021] 3. This ballpoint pen with easy refill replacement replaces the traditional rubber anti-slip sleeve with an anti-slip strip component. When it wears out or sheds, the anti-slip strip component can be easily replaced. Similar to replacing the grip tape on a badminton racket, the old anti-slip strip component is removed and attached to the pen holder with double-sided tape. The rubber anti-slip strip is then wrapped around the pen holder along the ribs, and finally sealed with double-sided tape at the end. Attached Figure Description
