Description
Technical Field
The invention relates to the field of writing pens, in particular to an anti-falling gel pen.
Background
The gel ink pen is a very common writing tool in people's daily life, can be used in many occasions, but the structure of its nib often takes place to damage very easily, especially when falling, as long as nib and ground take place the scraping, it is not smooth to write then lightly, the pen pearl falls in the oil cut-off, therefore the end of the life-span of a lot of gel ink pens often not the printing ink of internal storage writes to the greatest extent, but the nib destroys, especially in some public occasions, like places such as bank counter, company proscenium, all can use gel ink pen (sign pen), its probability that falls can rise at double, consequently can cause a large amount of wastes.
Aiming at the problems, a gel ink pen with an anti-falling function is designed by many people, and the principle of the gel ink pen is that a heavy object is arranged at the tail end of the gel ink pen, so that the gel ink pen falls off to ensure that the tail end touches the ground as far as possible to prevent the pen point from colliding with the ground.
Disclosure of Invention
Based on the above problems, the invention aims to provide an anti-falling gel-ink pen with good reliability and good protection effect.
Aiming at the problems, the following technical scheme is provided: an anti-falling gel ink pen comprises a pen holder and a refill, wherein the pen holder comprises a front pen holder and a rear pen holder positioned behind the front pen holder, the rear end of the front pen holder is provided with a front sleeving part, the front end section of the rear pen holder is provided with a rear sleeving part, the front pen holder and the rear pen holder are butted through a spring wire sleeve, two ends of the spring wire sleeve are respectively sleeved on the front sleeving part and the rear sleeving part, the spring wire sleeve is wound into a barrel through a spring wire, and the spring wires with adjacent pitches are mutually close to each other through elasticity; the pen comprises a front pen holder, a rear pen holder, a pen core, a push rod, an ejection spring and a spring, wherein the front pen holder is internally provided with the homing spring which is used for pushing the pen core towards the direction of the rear pen holder so that the pen point of the pen core is retracted into the front pen holder; when the pen is used, the front pen holder is held by hand and the rear pen holder is leaned against the tiger mouth position of the hand, the push rod pushes towards the front pen holder to enable the rear section of the pen core to be separated from the rear sleeve joint part, at the moment, the rear pen holder is pushed upwards by the tiger mouth position in a holding state to enable the rear pen holder to be bent relative to the front pen holder to cause the axes of the rear pen holder and the front pen holder to be intersected, and after the push rod is loosened, the rear end of the pen core is pushed by the homing spring to abut against the front end face of the rear sleeve joint part to prevent the pen core from; when the pen falls accidentally, the falling process is in a weightless state, the front pen holder and the rear pen holder lose relative bending moment in a hand-holding state, the spring wire sleeve corrects the axes of the front pen holder and the rear pen holder to be concentric again by utilizing the elasticity of the spring wire sleeve, the rear end of the pen core loses the support of the end face of the rear sleeve joint part, and the rear end of the pen core enters the rear sleeve joint part under the pushing of the homing spring to enable the pen core to retract into the front pen holder to prevent the pen core from being damaged when the pen core falls.
In the above-mentioned structure, utilize the posture that people daily write to guarantee that the refill of writing in-process is in the state of stretching out all the time, in case the emergence falls or when following the hand landing, the spring wire sleeve is corrected preceding pen-holder and back pen-holder axis for concentric messenger's refill and is retracted rapidly, guarantees that the nib of refill can retract into preceding pen-holder before striking ground, effectively prevents the nib and collides with the possibility of damaging, has the good reliability, advantage that protecting effect is good.
The invention is further set up that a refill retaining ring is arranged on the outer wall of the refill positioned in the front penholder, one end of the homing spring is abutted against the refill retaining ring, and the other end of the homing spring is abutted against the front end of the inner cavity of the front penholder; when the refill retracts into the front penholder, the end face of one end, facing the rear penholder, of the refill retaining ring abuts against the front end face of the front sleeving connection part.
In the structure, the pen core baffle ring is abutted to the front end face of the front sleeving part to provide axial limiting for the pen core.
The invention is further provided that the abutting force of the spring wires of adjacent pitches abutting each other through elastic force is larger than the compressed pushing force of the return spring.
In the structure, the phenomenon that the spring wire sleeve is stretched when the refill is pushed by the reset spring to abut against the rear sleeve joint part can be avoided.
The pen is further provided with a pressing cap at the exposed end of the push rod, and the spacing distance between the end face of the pressing cap facing one end of the front pen holder and the end face of the rear end of the rear pen holder is not less than the sliding stroke of the pen core in the front pen holder.
In the structure, the sleeve joint part can ensure that the push rod pushes the tail end of the refill out.
The invention is further arranged that the pressing cap is made of metal, so that the center of gravity of the whole penholder is positioned at one side of the backward penholder.
In the structure, the probability of the rear end of the pen holder contacting the ground when the pen holder falls is improved, the collision between the front end of the front pen holder and the ground can be reduced, and the possibility that the pen core cannot extend out in the follow-up use process due to the damage of the cone cap at the front end of the front pen holder is reduced.
The invention is further arranged that a push rod baffle ring is arranged on the outer wall of the push rod positioned in the rear penholder, one end of the ejection spring is abutted against the push rod baffle ring, and the other end of the ejection spring is abutted against the rear end of the rear sleeve joint part; when the push rod resets, the end face of the push rod baffle ring, which faces the tail end of the rear penholder, is abutted against the rear end face of the inner cavity of the rear penholder.
In the structure, the push rod blocking ring is used for supporting the ejection spring in an abutting mode and simultaneously can prevent the push rod from being separated from the rear penholder.
The invention has the beneficial effects that: the pen core in the writing process is always in the extending state by utilizing the daily writing posture of people, once the pen core falls or slides from a hand, the front pen holder and the rear pen holder are quickly corrected to be concentric by the spring wire sleeve, so that the pen core retracts, the pen point of the pen core before impacting the ground can be retracted into the front pen holder, the possibility of damage caused by knocking and bumping of the pen point is effectively prevented, and the pen core has the advantages of good reliability and good protection effect.
