Description

Technical Field

[0001] The utility model relates to the technical field of watercolor pens, in particular to an environmentally friendly and easy-to-use watercolor pen. Background Art

[0002] As we all know, traditional watercolor pen designs are mostly based on the principle of disposable use, that is, after the ink is used up, the entire pen including the plastic shell, ink container and other parts are usually discarded. This design model has exposed several significant problems in many years of application. The large-scale use and arbitrary discarding of disposable watercolor pens have aggravated the problem of plastic pollution and have had a serious impact on the natural environment, especially the marine ecosystem. The decomposition process of plastic is long and may take hundreds of years. During this period, harmful substances will be released, destroying the ecological balance. The mode of discarding after each use means that a large amount of available resources are frequently consumed instead of being recycled, which is a huge waste of limited resources. Therefore, it is necessary to propose a solution to this technical problem. Utility Model Content

DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1-4The utility model is an environmentally friendly and easy-to-use watercolor pen, comprising a watercolor pen body 1, a mounting groove is provided at the top of the watercolor pen body 1, a positioning groove is provided at the bottom of the mounting groove, a pen head 2 is provided between the bottom ends of the watercolor pen body 1, a sponge layer 3 is provided between the bottom end of the positioning groove and the pen head 2, a threaded groove is provided at the top outer side of the watercolor pen body 1, a top cover 4 is provided on the threaded groove, a mounting column 5 is provided between the top cover 4 and the mounting groove, a bearing seat 6 is provided at the bottom end of the mounting column 5, a positioning frame 7 is provided between the bottom end of the bearing seat 6 and the positioning groove, and an ink cartridge 8 is provided at the bottom end of the positioning frame 7 , an ink outlet tube 9 is provided between the ink cartridge 8 and the sponge layer 3, a rectangular groove is provided at the top of the positioning frame 7, a fixing hole is provided on the mounting column 5, a rectangular column 10 is provided on the fixing hole, the rectangular column 10 is against the rectangular groove, an elastic supporting mechanism is provided between the rectangular column 10 and the rectangular groove, and a pen cap 11 is provided at the bottom end of the watercolor pen body 1. In this embodiment, a person places the ink cartridge 8 on the positioning frame 7, and then inserts the positioning frame 7 into the positioning groove with the positioning groove facing downward, so that the ink cartridge 8 is against the positioning groove, and the ink outlet tube 9 of the ink cartridge 8 is inserted into the sponge layer 3, and the rectangular column 10 is pulled, and one side of the rectangular column 10 The end leaves the rectangular groove, the elastic supporting mechanism is squeezed and contracted, and then the top cover 4 is rotated. The top cover 4 is threadedly connected to the threaded groove of the watercolor pen body 1. The positioning frame 7 can move in a straight line through the bearing seat 6 and will not follow the rotation angle of the mounting column 5, so that one end of the ink cartridge 8 is against the positioning groove, and then the rectangular column 10 is loosened, and the elastic supporting mechanism supports the rectangular column 10. When the rectangular column 10 is aligned with the rectangular groove, the elastic supporting force of the elastic supporting mechanism can move the rectangular column 10 into the rectangular groove. If it is not aligned, the personnel slightly rotates the top cover 4 to adjust the angle between the rectangular column 10 and the rectangular groove. When the rectangular column 10 is aligned with the rectangular groove, the personnel can rotate the top cover 4 slightly to adjust the angle between the rectangular column 10 and the rectangular groove. After the rectangular grooves are aligned, the rectangular column 10 is inserted into the rectangular groove. At this time, the top cover 4 will not rotate on the threaded groove, which can effectively prevent the shaking of the structure during carrying and the like, and the top cover 4 will not loosen on the threaded groove, thereby ensuring that the ink cartridge 8 is firmly fixed. When a better ink cartridge 8 is needed, it is only necessary to pull the rectangular column 10, the rectangular column 10 leaves the rectangular groove, and then rotate the top cover 4, the top cover 4 leaves the threaded groove, so that the ink cartridge 8 can be quickly taken out for replacement. Only a better ink cartridge 8 is needed for reuse, which solves the problem of environmental pollution and waste of resources caused by directly throwing away traditional disposable watercolor pens after use, and is in line with the concept of environmental protection.

[0024] In the present embodiment, the elastic support mechanism includes a fastening groove and a fastening plate 12. The fastening groove is opened on one side of the fixing hole. The fastening plate 12 is located in the fastening groove and connected to the rectangular column 10. An elastic component 13 is provided between the top end of the fastening groove and the fastening plate 12. The fastening plate 12 is supported by the elastic component 13 between the top end of the fastening groove and the fastening plate 12. The rectangular column 10 is connected by the fastening plate 12, so that the rectangular column 10 can be stably inserted into the rectangular groove through the elastic supporting force of the elastic component 13. When the rectangular column 10 is pulled, the elastic component 13 is squeezed and contracted by the fastening plate 12, thereby facilitating one end of the rectangular column 10 to leave the rectangular groove.

[0025] In this embodiment, the elastic support mechanism is provided in plurality, and the plurality of elastic support mechanisms can make one end of the rectangular column 10 more stably inserted in the

[0026] In this solution, the elastic component 13 is a spring, which has the characteristic of good spring support, so it can stably elastically support the fastening plate 12.

[0027] In the present solution, the rectangular column 10 and the rectangular groove are both hexagonal structures. Since the rectangular column 10 with a hexagonal structure is located in the rectangular groove, the rectangular column 10 can be easily inserted into and abut against the rectangular groove.

[0028] In this solution, a handle 14 is provided at the top of the rectangular column 10 , and the rectangular column 10 can be easily pulled by holding the handle 14 .

[0029] In this solution, a sealing ring is provided on the inner wall of the top cover 4, and the sealing ring can improve the sealing performance between the top cover 4 and the thread groove.

[0030] In this solution, the rectangular column 10 is adapted to the rectangular groove. By adapting the rectangular column 10 to the rectangular groove, the rectangular column 10 can be more firmly placed in the rectangular groove.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
