Description

Writing implement

Technical Field

The utility model relates to a stationery especially relates to a writing tool.

Background

At present, writing pens (sign pens, oil pens, gel pens and the like) are essential stationery in daily life and work of people. The writing pen is divided into the following parts according to different using methods: writing instruments and cap-type writing pens, but are widely used due to the convenience of the writing instruments in operation. Chinese patent No. 201410701190.X discloses a sliding type writing instrument with a drying prevention device, mainly disclosing that a sealing member is provided in a pen case to seal a pen core, and the pen core drives a guide member to move together in the process of moving up and down. The guide part makes the lid of sealing member open in the process of moving towards the access hole of pen housing to when guide part moved to access hole position department, the lug will extrude and break out block portion and slide in moving the hole, make the nib of refill stretch out from access hole. Because the guide part is made of plastic materials, in the actual use process, along with the increase of the use time, the positioning force applied to the convex block by the clamping part of the guide part is gradually reduced. Thus, when the guide member does not reach the access hole, the projection easily breaks the engaging portion and slides into the moving hole. This results in incomplete opening of the cap, allowing the head of the cartridge to come into contact with the cap, which may cause excessive ink adhesion to the cap and affect the seal. How to design a writing stationery with good sealing performance to improve the use reliability is the technical problem to be solved by the utility model.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 to 7, the writing instrument of the present embodiment includes: the pen comprises a pen shell 1, an ink seat 2, a sealing component 3, a spring 4, a guide component 5 and a bump 6, wherein an access hole 11 is formed in one end of the pen shell 1, the bump 6 is arranged on the ink seat 2, a moving hole 51 is formed in the side wall of the first end of the guide component 5, a clamping part 52 is arranged at the inlet of the moving hole 51, the ink seat 2 is connected with the first end of the guide component 5, the sealing component 3 is connected with the second end of the guide component 5, the ink seat 2, the sealing component 3, the spring 4, the guide component 5 and the bump 6 are all arranged in the pen shell 1, and the spring 4 is clamped between the ink seat 2 and the sealing component 3; the inner wall of the pen housing 1 is provided with a protrusion 10, which protrusion 10 is intended to abut against the outside of the first end of the guide member 5 during its movement towards the access opening 11.

Specifically, the writing instrument of the present embodiment further includes a pen holder 12 disposed on the pen housing 1, a pen core 21 disposed on the ink holder 2, a cover 31 disposed on the sealing member 3 for sealing the pen core 21, and an openable cap 20 disposed on the ink holder 2. Regarding the specific assembly manner and structure form of the pen casing 1, the ink holder 2, the sealing member 3, the spring 4, the guiding member 5 and the protrusion 6, reference may be made to the description of the sliding type writing instrument with the anti-drying device disclosed in chinese patent No. 201410701190.X, which is not limited and repeated herein. In order to ensure that the guide member 5 can be moved into position to avoid the tip of the pen refill 21 from touching the cover 31, a projection 10 is provided on the inner wall of the pen housing 1. The protruding part 10 has a limiting effect on the first end of the guide member 5, so that the situation that the protruding block 6 props the clamping part 52 to enter the moving hole 51 due to the fact that the guide member 5 does not move in place in the moving process is avoided, and the pen core 21 cannot touch the cover 31.

The specific process is as follows: in the return extended state of the spring 4, the first end of the guide 5 abuts against the projection 10, with reference to the state shown in fig. 5. When the user presses the pen cap 20 to push the ink holder 2 to move toward the access hole 11, the protrusion 6 on the ink holder 2 abuts against the engaging portion 52 and drives the guide member 5 to move together; during the movement of the guide member 5, the first end of the guide member 5 cannot be spread due to the limitation of the first end by the protrusion 10, so that the guide member 5 can be reliably moved in place. During the pressing process, after the guide member 5 moves to the proper position, the first end of the guide member 5 will be separated from the limit of the protrusion 10, and as the user continuously presses the cap 20, the protrusion 6 will push the engaging portion 52 open and enter the moving hole 51, the ink holder 2 will slide relative to the guide member 5, and finally the pen core 21 will extend out of the access hole 11, and at this time, the spring 4 is in a compressed state. When the user presses the cap 20 again, the spring 4 pushes the ink base 2 to move in the reverse direction, and after the protrusion 6 is separated from the moving hole 51 beyond the engaging portion 52, the ink base 2 continues to drive the guiding member 5 to move in the reverse direction until the guiding member is reset.

Wherein, in order to ensure the smooth sliding of the guiding member 5, the inner wall of the pen housing 1 is provided with two oppositely arranged protrusions 10. In addition, the projection 10 is in a strip structure, and the projection 10 extends along the length direction of the pen casing 1 to meet the sliding requirement of the guide member 5. Preferably, the end of the protrusion 10 facing the access hole 11 is provided with an inclined surface 101, and the guide member 5 can smoothly slide by the inclined surface 101.

Further, the protrusion 6 is a convex strip, and the convex strip and the moving hole 51 both extend along the length direction of the pen casing 1. Specifically, the protruding block 6 is a protruding strip, and in the process of opening the writing instrument, one end of the protruding block 6 props up the engaging portion 52 to enter the moving hole 51 to slide, and the engaging portion 52 is always attached to two sides of the protruding block 6, so that the first end of the guide member 5 is always in a propped-up state, the guide member 5 is prevented from freely moving, and the use reliability is improved.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
