Detailed Description

A specific embodiment of the present invention will be described in detail with reference to fig. 1-3.

A double-end pen convenient to replace comprises a pen container 1, wherein two ends of the pen container 1 are respectively connected with a pen point 2, a hose connected with the pen points 2 is arranged in the pen container 1, two ends of the pen container 1 are respectively connected with a pen cap 3, and the pen points 2 are isolated and protected; in the using process, compared with the manner of fixing the pen cap at the end part of the pen barrel, which is not provided with the pen point, of sleeving the pen cap at the other end of the pen barrel in the prior art, in the embodiment, because the pen cap 3 is provided with the pen cap 3 at both ends, in order to fix the pen cap 3, the pen cap 3 of the embodiment is provided with bearing platforms 31 with equal height at the outer side of the sealing end and the inner side of the opening end, a clamping groove 32 is arranged above the bearing platform at the outer side of the sealing end of the pen cap 3, a clamping protrusion 33 is arranged below the inner side of the opening end, and meanwhile, arc grooves 11 are arranged at both ends of the pen barrel 1; when the pen cap is not used, the pen caps 3 are respectively sleeved at two ends of the pen cap 3, the clamping protrusions 33 are matched at the arc grooves 11, when the pen cap is used, the pen cap 3 at any end of the pen container 1 is taken down and sleeved on the pen cap 3 at the other end, the pen caps 3 are overlapped, the clamping protrusions 33 of the pen caps 3 are matched on the clamping grooves 32 of the other pen cap 3, and the bearing platform inside the pen cap 3 is in contact with the bearing platform outside the other pen cap 3.

The double heads of the pen cap are arranged to be backup to each other, usability is guaranteed, the pen cap can be sleeved on the pen container 1, the pen caps 3 can be sleeved with each other, and the pen cap has strong practicability.

When the pen cap 3 is sleeved, the air in the pen cap 3 is difficult to circulate outwards and is compressed, the pressure intensity exists in the pen cap 3, the installation is not facilitated, the acting force on the pen cap 3 always exists after the pen cap 3 is sleeved, and the similar pen cap 3 is easily separated from the pen container 1 or the pen cap 3 under the external collision, so that the air vent 34 is arranged in the pen cap 3, and the balance of the internal pressure intensity and the external pressure intensity of the pen cap 3 is maintained through the air vent 33 in the embodiment; preferably, the vent hole 34 is disposed at the slot 32, which is more attractive and more efficient in manufacturing process.

In this embodiment, the pen caps 3 can be sleeved with each other, but when the pen caps 3 are separated from each other, since the pen caps 3 and the pen container 1 are connected in the same manner, the interaction forces are almost the same, when the pen caps 3 are pulled out, the pen caps 3 and the pen container 1 may be separated and the pen caps 3 are still connected, and at this time, the pen caps 3 need to be separated again and then the pen caps 3 are respectively sleeved on the pen container 1, which is inconvenient to operate, based on this situation, the depth of the arc groove 11 of the pen container 1 is deeper than the depth of the clamping groove 32 of the pen caps 3, so that the depth of the clamping protrusion 33 in the arc groove 11 is also deeper, and the anti-pulling capability in the axial direction of the pen container 1 is also better; or, the magnetic strip is arranged at the arc groove 11 of the pen container 1, and the anti-pulling capacity in the axial direction of the pen container 1 is enhanced through the adsorption capacity of the magnetic strip on the pen cap 3.

In the embodiment, the pen points 2 are arranged at two ends of the pen container 1, the pen points 2 are connected with the flexible pipes into the pen container 1, and in order to control the length of the pen container 1, the flexible pipes connected with the pen points 2 and the axis of the pen container 1 have an offset distance, so that the flexible pipes connected with the pen points 2 are arranged in the pen container 1 side by side, the length of the pen container 1 is shortened, and the capacity of the flexible pipes is not reduced.

The connection between the pen point 2 and the pen container 1, the connection between the pen point 2 and the hose, and the structure and the distance involved in ink absorption and ink discharge are the prior art, and the description is omitted in this embodiment.

In conclusion, the pen cap provided by the utility model has the advantages that the double pen points are used as backups for each other, the embarrassing situation that a single pen point cannot be used due to obstacle is avoided, the pen cap can be sleeved on the pen container and can also be sleeved with each other, and the ventilation hole and the magnetic stripe are additionally arranged, so that the cap can be pulled out more smoothly.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
