In order to solve the technical problems, the utility model discloses a double-ended pen which can ensure the conventional service performance and aesthetic property of the pen and can not affect the writing fluency of the pen points at two ends, comprising a pen holder, two regulators, two pen points and two pen caps, wherein the number of the regulators, the pen points and the pen caps is two respectively, the two pen points are respectively arranged on the two regulators, the two pen caps are respectively sleeved at the outer sides of the two pen points, the insides of the two regulators are respectively provided with a water diversion core and a scale type ink supply device, one side of the two regulators far away from the pen points is provided with an external thread section, the pen holder is of a hollow structure, the two ends of the pen holder are respectively provided with an internal thread section, the internal thread sections at the two ends can be respectively screwed with the external thread sections on the two regulators, a baffle plate is also arranged in the hollow cavity of the pen holder, the partition plate divides the hollow cavity of the pen holder into a first ink cavity and a second ink cavity, the first ink cavity and the second ink cavity can directly store ink, the partition plate is a wavy plate, and the wavy partition plate extends from the internal thread section on one side of the pen holder to the internal thread section on the other end of the pen holder.

As an alternative of the technology of the utility model, the pen holder is made of transparent plastic.

As an alternative to the technique of the present invention, two of the regulators the external thread section has all been cup jointed with a flexible sealing ring.

The utility model has the advantages that:

the double-end pen of the utility model uses the wavy partition plate to separate two long and narrow ink cavities, when one end of the double-end pen is used for writing, the whole mass center of the ink in the ink cavity corresponding to the side pen point is higher than that in the conventional shorter ink sac, thereby improving the smoothness of ink outlet, not increasing the whole length of the pen holder, and ensuring the whole attractiveness of the pen body; meanwhile, the ink quantity in the ink cavity can be conveniently observed so as to inject ink in time. Additionally the utility model discloses be provided with the sealing washer at the coupling part of regulator and pen rod in the structure, increased the leakproofness that regulator and sealing washer closed soon, prevent that the ink of both sides from oozing outward and influencing user experience.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

It should be noted that all the directional indicators (such as upper, lower, left, right, front and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly.

In the description of the embodiments, the terms "disposed," "connected," and the like are to be construed broadly unless otherwise explicitly specified or limited. For example, the connection can be fixed, detachable or integrated; can be mechanically or electrically connected; either directly or through an intervening medium, or through internal communication between two elements.
