Description

Technical Field

[0001] The utility model relates to the technical field of stationery products, in particular to a marker pen which is convenient for ink filling. Background Art

[0002] A marker is a commonly used drawing and marking tool, also known as a marker or marker. It is usually filled with oil-based, water-based or alcohol-based ink and equipped with a thin and long tip, which can be used for drawing, marking and writing on various surfaces. Markers are widely used in many fields, such as art, design, office and education. Due to their bright colors and convenient use, markers are suitable for writing, drawing and marking on whiteboards, glass, cloth, paper and other smooth surfaces. There are various types of markers according to different needs and usage environments. For example, graffiti artists usually like to use fine-tipped markers to facilitate drawing small details; while in an office environment, markers with thick tips and erasable ink can be selected for easy writing and correction.

[0003] Existing marker pens are mainly divided into two types: disposable marker pens and refillable marker pens. Disposable marker pens have a short service life. Once the ink is exhausted, the ink cartridge cannot be replaced and can only be discarded, resulting in a waste of resources. Refillable marker pens allow users to open the top cover and inject ink into the interior to extend the service life. However, the top cover of existing refillable marker pens is difficult to open easily because it needs to maintain good sealing. Therefore, when time is tight and the user encounters that the marker pen is out of ink, the top cover cannot be opened quickly, which will cause irritability and anxiety, seriously affecting the user's mood. This brings great inconvenience to the user. Based on the above problems, a marker pen that is easy to refill is designed to solve the problems of existing marker pens. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that the top cover of the existing refillable marker pen is difficult to open easily due to the need to maintain good sealing, and the marker pen cannot be refilled conveniently, which brings great inconvenience to users in urgent need and even affects the user's mood.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] like Figure 1-5As shown, the utility model provides a technical solution: a marker pen that is easy to fill with ink, comprising: a clamping block mechanism 8, the clamping block mechanism 8 includes a top cover 81, a connecting block 82 is fixedly connected to the lower end of the top cover 81, a limiting groove 83 is provided on the side wall of the connecting block 82, a connecting rod 84 is fixedly connected to the lower end of the connecting block 82, a spring 85 is fixedly connected to the end of the connecting rod 84 away from the connecting block 82, and a guide tube 86 is fixedly connected to the middle part of the lower end of the connecting block 82.

[0028] In this example, the existing markers are mainly divided into two types: disposable markers and refillable markers. The service life of disposable markers is short. Once the ink is exhausted, the ink capsule cannot be replaced and can only be discarded, resulting in a waste of resources. The refillable marker allows the user to open the top cover 81 and inject ink into the interior to extend the service life. However, the existing refillable marker needs to maintain good sealing, which makes it difficult to open the top cover 81 easily. Therefore, when time is tight, when the user encounters a marker without ink, because the top cover 81 cannot be opened quickly, it will cause irritability and anxiety, which seriously affects the user's mood. This brings great inconvenience to the user. Based on the above problems, a marker that is easy to refill is designed to solve the problems of the existing markers. The block mechanism 8 includes a top cover 81, a connecting block 82, a limiting groove 83, a connecting rod 84 and a spring 85. The top cover 81 is located at the upper part of the block mechanism 8, and the lower end is fixedly connected to the connecting block 82. The lower end of the connecting block 82 is connected to the connecting rod 84, and the lower end of the connecting rod 84 is fixedly connected with a spring 85. The shape of the spring piece 85 matches the inner wall of the housing 1 and can fit completely, so as to play a limiting role during connection. Usually, the block mechanism 8 is connected to the upper end of the housing 1;

[0029] However, when using the marker pen, you may encounter a situation where the ink is insufficient and you need to add ink. In order to facilitate the addition of ink, the block mechanism 8 is designed to be quickly disassembled. The specific method of disassembly is to use a sharp object to squeeze the sharp corners at both ends of the spring sheet 85, which will cause the spring sheet 85 to shrink inward and away from the slot 5 on the outer wall of the shell 1, so that the block mechanism 8 is quickly ejected, which is convenient for disassembly and ink addition operations;

[0030] A limiting groove 83 is provided on the side wall of the connecting block 82. The limiting groove 83 is connected to the limiting block 4 on the inner wall of the housing 1 to play a limiting role and prevent the top cover 81 from shifting during the installation process;

[0031] A guide tube 86 is provided at the lower end of the connection block 82. The guide tube 86 is connected to the sponge 7 inside the housing 1. When adding ink, the ink will fill the entire sponge 7. As the ink is used, the ink in the lower part will be consumed, and the ink in the upper part cannot be used. Therefore, the guide tube 86 is designed to open the channel of the sponge 7, so that the ink settles downward and accumulates at the bottom, ensuring that the ink in the upper part is continuously available;

[0032] These designs allow the user to easily disassemble the block mechanism 8 to perform ink adding operations and ensure that the top cover 81 is installed and aligned. At the same time, through the design of the guide tube 86, the ink is effectively utilized and the ink in the sponge body 7 is kept sufficient.

[0033] Example 2

[0034] like Figure 2-5 As shown, the lower end of the clamping block mechanism 8 is movably connected to the shell 1, the connecting block 82 is movably connected to the inner wall of the shell 1, the upper inner wall of the shell 1 is provided with a mounting groove 2, one side of the mounting groove 2 is connected with a sealing ring 3, the sealing ring 3 connected to one side of the inner wall of the mounting groove 2 is movably connected to the connecting block 82, the upper inner wall of the shell 1 is fixedly connected with a limiting block 4, the four limiting blocks 4 provided on the upper inner wall of the shell 1 are limitedly connected with the limiting groove 83 provided on the outer wall of the connecting block 82, the side wall of the shell 1 is provided with a clamping groove 5, the shell A card slot 5 is provided on both sides of the outer wall of the housing 1, one side of the card slot 5 is carded with the spring piece 85, one side of the inner wall of the card slot 5 is fixedly connected with a fixing block 6, the fixing block 6 provided on one side of the card slot 5 is correspondingly connected with the spring piece 85, a sponge body 7 is provided inside the housing 1, a mounting block 9 is connected to the lower end of the housing 1, a pen head 10 is connected to the lower end of the mounting block 9, a guide tube 11 is fixedly connected to the upper end of the pen head 10, the guide tube 86 and the guide tube 11 are both movably connected with the sponge body 7, and a pen cap 12 is provided at the lower end of the pen head 10.

[0035] In this example, by opening a mounting groove 2 on the inner wall of the upper end of the housing 1, and connecting a sealing ring 3 to one side of the inner wall of the mounting groove 2, the inner side of the sealing ring 3 is connected to the connecting block 82, which can play a sealing role, ensuring that the ink of the marker pen will not evaporate due to poor sealing, thereby improving the use efficiency. This design ensures that the ink will not be wasted due to evaporation, and maintains the stable quality of the ink of the marker pen;

[0036] In order to prevent a gap from being left between the spring piece 85 and the card slot 5 on the outer wall of the housing 1, a fixing block 6 is provided to be connected to the inner wall of the card slot 5 and to be correspondingly connected to the spring piece 85 to play a sealing role. This design can prevent external air from entering and avoid ink volatilization;

[0037] When in use, the ink in the sponge 7 will flow out through the pen tip 10 for the user to use. However, in the existing marker pen, the sponge 7 will shake inside, resulting in the inability to fully utilize the ink. There will often be residual ink or the ink cannot be continuously supplied. This may cause the user to mistakenly believe that the marker pen has no ink, resulting in ink overflowing and dirtying the hands when disassembling. For this purpose, a guide tube 11 is provided at the upper end of the pen tip 10. The guide tube 11 can guide the ink in the sponge 7 to the pen tip 10, so that the ink in the sponge 7 can be fully utilized.

[0038] Working principle:

[0039] like Figure 1-5 As shown, in order to make full use of the ink in the sponge 7, the utility model is designed with a guide tube 11 to enable the ink to flow effectively to the pen head 10 to improve the use efficiency. However, after long-term use, the ink may dry up, so it is necessary to add ink to the sponge 7. In order to achieve rapid ink addition to the sponge 7, a device is designed, namely a block mechanism 8;

[0040] A clamping block mechanism 8 is provided at the upper end of the shell 1, wherein the top cover 81 is connected to the connecting block 82. When the top cover 81 needs to be removed, the user only needs to use a sharp object to apply pressure to the spring piece 85 connected to the inner wall of the card slot 5 on the outer wall of the shell 1, and the spring piece 85 will shrink inward and disengage from the card slot 5. At this time, the user can easily remove the top cover 81, and then perform the ink filling operation of the sponge 7. After the ink filling is completed, the connecting block 82 connected to the lower end of the top cover 81 is connected to the limit block 4 on the inner wall of the shell 1 corresponding to the limit slot 83, and pressed downward to the appropriate position. At this time, the spring piece 85 will be re-engaged with the card slot 5 on the outer wall of the shell 1, completing the ink filling operation, and can be used normally;

[0041] The lower end of the connecting block 82 is provided with a guide tube 86, which acts on the upper end of the sponge 7, so that the ink settles downward and accumulates at the bottom, ensuring that the ink in the upper part is continuously available. This design is intended to ensure sufficient ink and increase the service life of the marker.

[0042] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
