Description

Technical Field

[0001] The invention belongs to the technical field of push ballpoint pens, and in particular relates to a push ballpoint pen with a pressing pen clip. Background Art

[0002] The click-and-turn ballpoint pen with a click-and-turn wheel structure has a click wheel, a turn wheel, and a rib groove arranged on the inner wall of a container where the click wheel and the turn wheel are located (such as the inner wall of a pen holder or the inner wall of a bushing added to the pen holder) for the click wheel and the turn wheel to move up and down and control their rotation as structural elements. It is flexible to click, has a good hand feel, and is easy to use, and is therefore very popular among people.

[0003] There are two types of push ballpoint pens: top push ballpoint pens and side push ballpoint pens. The top of the top push ballpoint pen is difficult to use for other purposes. If other functional parts are set on the top of the pen, such as a touch head that can be used for touch input on an electronic touch screen, or an eraser block that can erase erasable ink marks, and the other functional parts are used as a push part for finger pressing, since the touch head and the eraser block are both made of soft materials, and a gap needs to be left on the inner wall of the touch head, the eraser block will be constantly worn during use, so the push action will be unsmooth and the hand feel will be very poor;

[0004] Chinese invention patent: Application number CN201310216721.1, Publication number CN103273765B discloses a side-press ballpoint pen, including a pen holder, a press wheel, a rotating wheel, and a pen core. The pen holder extends along its longitudinal axis between its upper end and lower end, and its lower end is in a conical shape with a gradually narrowing cross section. The lower end is provided with a circular hole for the pen head at the lower end of the pen core to extend or retract. The press wheel, the rotating wheel, and the pen core are located inside the pen holder and are connected in sequence from top to bottom. The inner wall of the pen barrel or the inner wall of the bushing provided therein is provided with a rib groove for the push wheel and the rotating wheel to move up and down and control the rotation thereof; the lower part of the pen core is fitted with a lower spring, characterized in that a straight groove is provided on the upper part of the pen barrel, and a push piece which can slide up and down along the straight groove is provided at the straight groove, and the push piece includes an outer piece located on the outer side of the pen barrel suitable for being pushed by a finger, and an inner piece located inside the pen barrel for driving the push wheel and the rotating wheel, and the inner piece is located above the push wheel; so that the top end of the pen can be used for other purposes;

[0005] In actual use, the push piece of the ballpoint pen is not part of the pen clip, and the ballpoint pen is controlled by sliding. This may cause the push piece to be accidentally touched when the pen clip is used, causing the pen tip to retract, which is inconvenient to use. At the same time, the sliding push piece connects the inside of the pen barrel with the outside world, which may cause foreign matter to easily enter the inside, causing the push mechanism to get stuck and shortening the service life. For this reason, we have designed a push ballpoint pen with a pressed pen clip to solve the above problems. Summary of the invention

Specifically, the push-type ballpoint pen with a press pen clip includes an upper pen barrel 1, a first telescopic rod 4, a rotating wheel 10, a push wheel 11 and a trapezoidal push block 12.

[0028] The upper pen barrel 1 is provided with a first refill cavity 1-1, a thread groove 1-4 is provided at the opening of the first refill cavity 1-1, a press wheel groove 1-2 is provided on the inner wall of the first refill cavity 1-1, a through hole 1-3 is provided on the first refill cavity 1-1, the through hole 1-3 is connected to the outside, a press wheel 11 is provided in the first refill cavity 1-1, a press wheel gear 11-1 is provided on the press wheel 11, the press wheel gear 11-1 is located at the press wheel groove 1-2, and can slide back and forth along the press wheel groove 1-2, a rotating wheel 10 is rotatably provided in the press wheel 11, and the rotating wheel 10 is provided with a press wheel gear 11-1. A rotating wheel tooth 10-1 is fixedly arranged, and a click wheel transmission is performed between the rotating wheel tooth 10-1 and the click wheel tooth 11-1. A trapezoidal push block 12 is slidably arranged in the first refill cavity 1-1, and the trapezoidal push block 12 is slidably connected to the click wheel 11. A first telescopic rod 4 is fixedly arranged on the trapezoidal push block 12, and the first telescopic rod 4 is located in the through hole 1-3 and can slide back and forth along the through hole 1-3. The click transmission of the rotating wheel 10 and the click wheel 11 can be controlled by pressing the pen clip 3, so that the top end of the upper pen barrel 1 can be used for other purposes, with good hand feel and easy use.

[0029] A lower pen barrel 2 is arranged on the thread groove 1-4, a second refill cavity 2-1 is opened in the lower pen barrel 2, a threaded opening 2-2 is arranged on one side of the second refill cavity 2-1, the threaded groove 1-4 and the threaded opening 2-2 are threadedly connected, a refill 8 is placed in the second refill cavity 2-1, a refill spring 9 is placed between one end of the refill 8 and the second refill cavity 2-1, and the other end of the refill 8 is located in the first refill cavity 1-1 and contacts and abuts against the rotating wheel 10.

[0030] A telescopic cavity 4-1 is provided at one end of the first telescopic rod 4 located outside, and a second telescopic rod 13 is slidably arranged in the telescopic cavity 4-1. The second telescopic rod 13 and the telescopic cavity 4-1 are connected by a telescopic spring 14. A spring cavity 4-2 is provided on an inner wall of one side of the telescopic cavity 4-1, and a pull rod 7 is slidably arranged in the spring cavity 4-2. One end of the pull rod 7 is in contact with and abuts against the second telescopic rod 13, and the other end of the pull rod 7 is located outside. A connecting plate 16 is fixedly provided on the pull rod 7, and the connecting plate 16 and the spring cavity 4-2 are connected by a reset spring 15. The pen clip 3 can control the extension and retraction of the pen core 8 and can also clamp it. The clamping process will not affect the pen core 8. At the same time, through the extension and retraction of the first telescopic rod 4 and the second telescopic rod 13, the pen clip 3 can be clamped on thicker objects without breaking.

[0031] A pen clip 3 is rotatably arranged on the outer side of the upper pen barrel 1. The upper pen barrel 1 and the pen clip 3 are connected via a connecting shaft 5.

[0033] When using the push-type ballpoint pen, the user presses the bottom end of the pen clip 3, and the pen clip 3 rotates to drive the first telescopic rod 4 to move, and the first telescopic rod 4 drives the trapezoidal push block 12 to move, and the trapezoidal push block 12 drives the push wheel 11 to move toward the rotating wheel 10. The rotating wheel 10 drives the pen core 8 to move while rotating. At this time, the wheel gear 10-1 on the rotating wheel 10 enters the shorter push wheel groove 1-2 and buckles, and the pen core 8 is extended from the lower pen barrel 2. The user can use the push-type ballpoint pen normally. When the user presses the bottom end of the pen clip 3 again, the wheel gear 10-1 on the rotating wheel 10 enters the longer push wheel groove 1-2 and buckles, and the pen core 8 is retracted into the lower pen barrel 2. After each pressing, the trapezoidal push block 12 returns to its original position under the action of the pen core spring 9, and the pen clip 3 can be pressed again;

[0034] When the user needs to clamp the pen with the pen clip 3, the pull rod 7 can be pulled. After the pull rod 7 is no longer in contact with the second telescopic rod 13, it is extended under the action of the telescopic spring 14. At this time, the pen clip 3 rotates around the connecting shaft 5, and the bottom end of the pen clip 3 contacts and abuts against the outer side of the upper pen barrel 1. The user can clamp the push-type ballpoint pen by rotating the pen clip 3. At this time, rotating the pen clip 3 is pushing, and will not move the trapezoidal push block 12, which will not affect the normal use of the push-type ballpoint pen.
