Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," "up," "down," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The invention will be further described with reference to the accompanying drawings and specific embodiments:

as shown in fig. 1, 2 and 3, a structure capable of replacing a pen point is characterized by comprising a pen nib 1 and a pen cap 3, wherein the pen nib 1 is sleeved with the detachable pen cap 3, and one end of the pen nib 1 sleeved with the pen cap 3 is detachably connected with the pen point 2; the pen cap 3 completely covers the pen point 2;

the pen point 2 comprises a fixed seat 20 and a pen core 23, a groove 22 is formed in the outer side of the fixed seat 20, and a coaxial guide post 21 is arranged at the upper end of the fixed seat; the guide post 21 is detachably connected with the pen nozzle 1; a pen core 23 penetrating through the axis of the guide post 21 is arranged in the middle of the fixed seat 20;

as shown in fig. 3, the pen cap 3 includes two or more keys 30 symmetrically disposed, one end of each key 30 is fixedly connected with the pen cap 3, and the other end is a free end; a fixture block 32 is arranged on the inner side of the free end of the key 30;

when the cap 3 is in the assembled state and the key 30 is not acted by external force, the latch 32 is far away from the groove 22; when the cap 3 is in the assembled state and the free end of the key 30 is under the action of external force, the latch 32 is engaged with the groove 22;

in the embodiment, a reasonable pen point disassembly structure is formed by arranging the groove 22 on the pen point 2 and arranging the key 30 on the pen cap 3; when the original pen point 2 is damaged and needs to be replaced, the pen cap 3 is assembled on the pen nib 1, the free end of the key 30 on the pen cap 3 is pressed downwards, the clamping block 32 is meshed with the groove 22 of the fixing seat 20 at the moment, the pen cap 3 is disassembled with force at the moment, the pen cap 3 drives the pen point 2 to move, so that the original damaged pen point 2 is disassembled from the pen nib 1, then the key 30 is loosened, the disassembled pen nib 1 can be discarded, and the disassembly of the pen point 2 is completed; the technology can prevent ink from splashing on hands in the dismounting process, and can conveniently and quickly dismount the pen point 2 without the help of an external tool.

On the contrary, when a new pen point 2 needs to be installed, the new pen point 2 is placed in the pen cap 3, then the free end of the key 30 is pressed to enable the fixture blocks 32 to be meshed with the grooves 22, and finally the pen cap 3 is pressed with force, so that the new pen point 2 is installed on the pen nozzle 1, and the installation of the pen point 2 is completed; in the installation process, the pen point is well protected, and the installation is convenient and fast.

Further, the pen cap 3 is connected with the pen nozzle 1 through threads; adopt threaded connection can make the dismouting process more steady, prevent to cause nib 1, nib 2 to damage.

Furthermore, the guide post 21 and the pen nib 1 are in interference fit, and the disassembling tension is 0.05-0.3N.

Further, the material of the fixing base 20 is copper.

Further, the groove 22 is a 360-degree annular groove with a rectangular or round-bottom rectangular cross section; the 360 degree annular groove design facilitates engagement with the latch 32.

Further, as shown in fig. 3, a key boss 31 is arranged on the outer side of the free end of the pen cap 3, and the key boss 31 is higher than the outer diameter of the pen cap 3; the key boss 31 improves the touch feeling of the key, increases the pressing force of the key, and enables the fixture block to be more tightly attached to the groove.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the principle of the present invention, and these modifications and variations are also considered as the protection scope of the present invention.
