Description

TECHNICAL FIELD

[0001] The utility model relates to the field of marking pen, especially a straight liquid type propylene marking pen with a protection structure. BACKGROUND

[0002] Through searching Chinese patent, the publication number is: CN217993940U, a convex point antiskid marking pen belongs to the technical field of marking pen. Its main purpose is to solve the problem that the ink in the existing marking pen is connected to the two pen tips of the marking pen, so that the ink will also flow to the pen tip when not in use, which is easy to evaporate and cause waste of ink pigment. The technical scheme is as follows: a pen shell is provided with an ink strip inside, the pen shell is fixedly installed with a first pen head and a second pen head at both ends respectively, and a ink flow control mechanism is arranged between the ink strip and the first pen head and the second pen head. When the convex point antiskid marking pen is not in use or is paused, the control rod at both ends of the pen shell is actuated, the circular tray pushes the adapter seat to separate it from the corresponding first pen head and second pen head, the ink in the ink strip no longer flows to the first pen head and second pen head, thereby effectively reducing the evaporation of ink pigment and reducing the waste of ink pigment, and the service life of the marking pen is improved.

[0003] The existing marking pen has poor sealing performance. The existing marking pen adopts a whole pen sleeve, and the pen sleeve and the pen barrel are sealingly matched. Since the pen sleeve is a whole, the size of the pen sleeve will be deformed greatly during injection molding. The deformation of the pen sleeve will cause the inner circle of the pen sleeve to be "out of round". After the "out of round" pen sleeve and the pen barrel are assembled with each other, a good sealing environment cannot be formed, the sealing effect is reduced, the ink in the pen barrel will leak out or the finished product pen cannot be written, and the water guide core cannot be protected. After the water reservoir of a general marking pen is matched with the water guide core, the water guide core extends a small section and is immersed in the ink. The function of the water guide core is to absorb the ink. Since the ink of the propylene marking pen has the characteristics of easy solidification, the pen body needs to be shaken before use to stir the solidified ink evenly by the steel bar in the pen body. As the use frequency of the product increases, the amount of ink will become less and less, and finally the water guide core will be exposed to the ink. During the process of stirring the ink, the steel bar will touch the head of the water guide core. Since the water guide core is made of fiber, after the steel bar touches the water guide core, the water guide core will be displaced or the contact part will be damaged under the action of the shaking force, finally reducing the service life of the product. In order to solve the above-mentioned problems, the utility model provides a straight liquid type propylene marking pen with a protection structure. UTILITY MODEL CONTENTS
