Description

Technical Field

[0001] The utility model relates to the field of marker pens, and more specifically, to a multi-purpose marker pen. Background Art

[0002] A marker pen, also known as a permanent marker, is a colored pen used for writing or drawing. It contains ink and usually comes with a cap. The pigment in a marker pen is volatile, making it suitable for quick, one-time drawings. It is often used for designing items, advertising slogans, posters, and other artistic endeavors. It produces thick, uniform lines.

[0003] Chinese patent CN219667820U discloses an adjustable marker pen, comprising a pen body and a fixing mechanism disposed on the inner wall of the pen body, the fixing mechanism comprising a locking assembly and a reset assembly; the locking assembly comprising a pen cap, a locking rod, and a locking slot. The pen cap is locked and connected to the top of the pen body, the outer wall of the pen cap is fixedly connected to the locking rod that is locked and connected to the inner wall of the pen body, and the inner wall of the pen body is provided with a locking slot at the connection between the locking rod and the locking rod. Due to the provision of the locking rod, in daily use of the marker pen, the pen cap is often rotated to be installed between the pen cap and the marker pen by means of a thread, which is quite cumbersome and affects the user's efficiency in changing the ink. The pen cap can be inserted into the pen body, and the spring is compressed under the connection of the connecting plate. At the same time, the locking rod is driven to slide along the inner wall of the locking slot, and the pen cap is rotated so that the locking rod fixed to the pen cap is locked and fixed in the locking slot, thereby achieving a control operation that improves the convenience of installing the pen cap and the marker pen.

[0004] However, in actual use, if the existing marker pen only writes in a single color, when markers of different colors are needed, it is necessary to carry multiple markers of different colors, which has certain limitations. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a multi-purpose marker pen. By shortening the length of a single marker pen, multiple marker pens of different colors are assembled and connected through connecting components at both ends to form a marker pen. When a corresponding color is needed, the marker pen of the corresponding color can be installed at the bottom. In this way, one marker pen can be used to write content in different colors, and it is also more convenient to carry, thereby increasing the practicality of the marker pen.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a multi-purpose marker pen, comprising:

[0007] The main body shell and the pen cap are provided with a plurality of main body shells, and the upper and lower ends of the main body shells are provided with connecting components, and the plurality of main body shells are assembled in sequence through the connecting components, and the bottom end of the main body shell is fixedly installed with a pen head;

[0008] An upper cover is mounted on the top of the main housing, and a storage slot matching the pen tip is provided on the outer surface of the top of the upper cover;

[0009] The retaining ring is sleeved on the outer surface of the main body shell, and the outer surfaces of the main body shell and the retaining ring are both provided with through holes.

[0010] Furthermore, the connecting assembly includes a first connecting ring fixedly installed at the bottom end of the pen tip, and a connecting groove matching the first connecting ring is opened at the top of the upper cover. The upper cover is threadedly connected to the first connecting ring through the connecting groove, and the marker is assembled and connected through the connecting assembly.

[0011] Furthermore, a second connecting ring is fixedly installed on the bottom end of the pen cap, and the second connecting ring matches the connecting groove. The pen cap is threadedly connected to the upper cover through the second connecting ring. A storage groove and a connecting groove are provided on the pen cap, so that the pen cap can be installed on the pen tip.

[0012] Furthermore, an observation window is provided on one side of the outer surface of the main shell. The observation window is made of transparent plastic material, and the amount of pigment inside the main shell can be understood through the observation window.

[0013] Furthermore, a knob is inserted into the outer surface of one side of the retaining ring, and the knob is threadedly connected to the retaining ring, so that the through hole on the surface of the main shell is closed by the retaining ring.

[0014] Furthermore, a limiting groove is provided on the outer surface of the main body shell, and one end of the knob passes through the retaining ring and is inserted into the limiting groove, and the retaining ring is limited and fixed by the knob being inserted into the limiting groove.

[0015] The technical effects and advantages of this utility model are:

[0016] 1. By shortening the length of a single marker pen, and then assembling and connecting multiple marker pens of different colors through the connecting components at both ends to form a marker pen, when the corresponding color is needed, the marker of the corresponding color can be installed at the bottom. In this way, one marker pen can write content of different colors, and it is also more convenient to carry, which increases the practicality of the marker pen;

[0017] 2. With the provided retaining ring, when you need to inject paint into the marker pen, first turn the knob to disengage one end of the knob from the limiting groove of the main shell, release the limit on the retaining ring, then turn the retaining ring to align the through hole on the retaining ring with the through hole on the main shell, and then inject the paint into the main shell from the through hole, which is more convenient.
