Detailed Description

The following description of the embodiments of the present utility model will be made apparent and fully in view of the accompanying drawings, in which some, but not all embodiments of the utility model are shown. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

A pen as shown in fig. 1 to 4 comprises a holding part 800 made of hard material, the holding part is axially penetrated inside, and a pen tongue 600 is inserted into the holding part 800 to suck and accumulate ink. A nib 700 is mounted at the front end of the tongue, a middle slit 710 is formed in the middle of the nib, and the middle slit draws out the ink accumulated in the tongue by capillary action and writes on the paper through the tip of the nib in contact with the writing paper. It should be noted that, a core 500 is connected to the rear end of the pen tongue, and an ink bag 400 for storing ink is detachably inserted to the rear end of the core, so that the ink in the ink bag can be timely replenished into the pen tongue. A pen tube 200 is further covered outside the ink bag, and is detachably screwed on the screw part at the rear end of the holding part 800 to protect the ink bag.

It should be noted that, keeping the gap between the center joints at a proper position is a necessary condition that ink can be continuously and stably supplied to the pen point during writing, and if the pen holding posture is incorrect, the stress of two parts of the pen point separated by the center joints is uneven, the condition that the gap between the center joints is too small due to the stress of one side of the pen point is very easy to occur, the center joints cannot perform capillary action well, and the ink is easy to break during writing, so that the pen state is ensured through the accurate pen holding posture.

In order to meet the above requirement, namely, the hemisphere 720 of the front end of the nib in the pen is abutted against the writing paper, the nibs on both sides of the middle seam are uniformly stressed, and a rubber sleeve 300 is sleeved outside the holding part 800. In detail, the rubber sleeve is provided with three positioning grooves 320 which are uniformly distributed in the axial direction, wherein two positioning grooves are symmetrically arranged on the center joint 710 on the pen point, and the rest positioning grooves 320 are necessarily positioned in the plane where the center joint 710 and the axis of the pen are positioned.

In this state, when the pen is pinched for writing, only the thumb and the index finger are required to fall into the positioning grooves on the two sides of the center joint, and the middle finger enters the rest of the positioning grooves 320, so that the hemisphere 720 at the front end of the pen nib faces the writing paper.

As a further improvement of the above embodiment, at least one of the two end surfaces of the gum cover is in a wave-like structure in order to prevent deviation of positioning caused by relative rotation between the gum cover 300 and the grip portion 800. Meanwhile, the grip 800 is provided with a stopper 830 which is clamped at both ends of the gum cover. It should be noted that, this spacing ring also adapts to the laminating with the terminal surface that is the gum cover of wave form, and then plays and prevents gum cover pivoted effect. Still further, at least one limiting groove 310 extending along the axial direction of the pen is provided on the inner surface of the gum cover 300, and at the same time, a clamping strip 820 adapted to the limiting groove 310 is provided on the surface of the holding portion 800. When the two ends of the rubber sleeve are attached to the limiting rings, the clamping strips are embedded in the limiting grooves 310.

On the premise of ensuring the buffer and pressure reduction functions of the rubber sleeve, the rubber sleeve is kept light and thin as much as possible, and the thickness of the rubber sleeve is optimal between 1.5 and 2mm.

In addition, in order to ensure the fit between the gum cover and the grip part, an adaptation groove 810 adapted to the positioning groove 320 of the gum cover 300 is provided on the grip part 800. It is to be noted that after the adaptation groove is adopted, the overall thickness of the rubber sleeve can be effectively ensured to be uniform, and the defective rate in casting molding can be effectively reduced. And after the adaptation groove is arranged, the supporting effect of the holding part on the positioning groove can be more uniform.

In this embodiment, in order to protect the nib, a cap 100 is detachably sleeved on the holding portion 800 to cover the holding portion and the nib.

In order to improve the hand feeling during writing, the holding part and the pen tube are made of metal materials, so that the pen manufactured by the scheme gives a stable feel to people compared with the weight of the pen made of plastic materials.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
