[0003] Chinese patent application CN202320054120.4, entitled "Self-filling Portable Color Chart," discloses a self-filling portable color chart. Existing color charts are mostly similar to the patented one, simply placing multiple color charts on a ring and unfolding them in a fan-shaped manner for use. This design has significant limitations in practical applications; the color charts tend to stack excessively during unfolding, leading to inefficiency and inconvenience when searching for specific colors. This structural design fails to fully consider the convenience and efficiency of users in actual use and has considerable room for improvement. Therefore, a self-filling portable color chart is needed. Utility Model Content

[0004] To address the aforementioned technical problems, the purpose of this utility model is to overcome the issue of color cards being stacked and making them inconvenient to find in the prior art.

[0005] To achieve the above objectives, this utility model provides a self-filling portable color card, comprising: a number of rectangular base plates whose long sides are sequentially hinged by hinge shafts and can be folded and stored; each rectangular base plate has a first flange protruding outward from both edges to form a receiving space; and each receiving space can be detachably fitted with a cover plate.

[0006] The accommodating space is provided with at least one dividing protrusion to divide the accommodating space into several individual color card spaces. Each color card space can hold a color card. The cover plate is provided with several windows that correspond one-to-one with the several color card spaces.

[0007] Preferably, the short side of the rectangular base plate is equipped with a limiting mechanism that connects to the short side of the adjacent rectangular base plate so that the maximum unfolding angle of the two adjacent rectangular base plates is an obtuse angle, and the several sets of rectangular base plates are distributed in a wave-like shape after unfolding.

[0008] Preferably, the short side of the rectangular base plate is provided with a mounting flange of the same length direction, one end of the mounting flange is provided with a mounting hole, and the other end of the mounting flange is provided with a strip groove of the same length direction.

[0009] The limiting mechanism includes a hinge bolt mounted on the mounting hole and parallel to the hinge axis, and a limiting rod with one end hinged to the hinge bolt. The end of the limiting rod away from the hinge bolt has a cylindrical part that is slidably inserted into a strip groove on an adjacent mounting flange.

[0010] Preferably, each color card space is provided with a frame-shaped limiting member that fits against the side wall of the color card space, one side of the frame-shaped limiting member is in contact with the color card, and the other side of the frame-shaped limiting member is in contact with the cover plate.

[0011] Preferably, one of the cover plates is provided with at least two countersunk holes, and the other cover plate is provided with at least two threaded portions corresponding to the countersunk holes. The rectangular base plate is provided with a through mounting hole corresponding to the countersunk holes, and each countersunk hole is provided with a mounting bolt that passes through the through mounting hole and connects to the threaded portion.

[0012] Preferably, it also includes elastic rings for fitting onto several rectangular base plates after folding.

[0013] According to the above technical solution, the self-filling portable color card provided by this utility model has the following beneficial effects when used:

[0014] Firstly, two adjacent rectangular base plates can be unfolded around the hinge axis, so several rectangular base plates can be unfolded at the same time, allowing you to see several color cards on the same side of several rectangular base plates at the same time. This makes it easy to quickly find the color card you need for comparison, and the operation is simple and convenient.

[0015] Secondly, both sides of the rectangular base plate have storage space, which can carry twice the number of color cards, making it highly practical.

[0016] Thirdly, the color cards to be used can be placed in the corresponding color card space according to actual usage needs.

[0017] Other features and advantages of this utility model will be described in detail in the following detailed description section; and all parts not covered in this utility model are the same as or can be implemented using existing technology. Attached Figure Description

[0026] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0027] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0028] like Figure 1-5 As shown, a self-filling portable color card includes: a number of rectangular base plates 1 whose long sides are sequentially hinged by hinge shafts and can be folded and stored; each rectangular base plate 1 has a first flange 2 protruding outward from both edges to form a receiving space; and each receiving space can be detachably fitted with a cover plate 3.

[0029] The accommodating space is provided with at least one dividing strip 4 to divide the accommodating space into several individual color card spaces. Each color card space can hold a color card 5. The cover plate 3 is provided with several windows 6 that correspond one-to-one with several color card spaces.

[0030] When in use, the color card 5 to be used can be placed into the corresponding color card space according to the actual needs. The two adjacent rectangular base plates 1 can be unfolded around the hinge axis, so several rectangular base plates 1 can be unfolded at the same time, and several color cards 5 on the same side of several rectangular base plates 1 can be seen at the same time. The color card 5 that needs to be found can be quickly found for comparison. The operation is simple and convenient. In addition, both sides of the rectangular base plate 1 are provided with a holding space, which can carry twice the number of color cards 5, making it highly practical.

[0031] The short side of the rectangular base plate 1 is equipped with a limiting mechanism that connects to the short side of the adjacent rectangular base plate 1 so that the maximum unfolding angle of the two adjacent rectangular base plates 1 is an obtuse angle. After unfolding, the rectangular base plates 1 are distributed in a wave-like pattern.

[0032] The limiting mechanism ensures that the maximum unfolding angle of two adjacent rectangular base plates 1 is obtuse, and the unfolded rectangular base plates 1 form a wave shape. When folding, the limiting mechanism restricts the two adjacent rectangular base plates 1 to fold in only one direction. Therefore, by simply closing the two outermost rectangular base plates 1, the rectangular base plates 1 can be folded up, making the operation simple and convenient.

[0033] The rectangular base plate 1 has a mounting flange 7 protruding from its short side with the same length direction. One end of the mounting flange 7 is provided with a mounting hole 8, and the other end of the mounting flange 7 is provided with a strip groove 9 with the same length direction.

[0034] The limiting mechanism includes a hinge bolt mounted on the mounting hole 8 and parallel to the hinge axis, and a limiting rod 10 with one end hinged to the hinge bolt. The end of the limiting rod 10 away from the hinge bolt has a cylindrical part 11 that is slidably inserted into the strip groove 9 on the adjacent mounting flange 7.

[0035] When the two adjacent rectangular base plates 1 are unfolded, the limiting rod 10 rotates around the hinge bolt, and the cylindrical part 11 slides in the strip groove 9. When the cylindrical part 11 slides to the end of the strip groove 9, the two adjacent rectangular base plates 1 are unfolded to the maximum angle.

[0036] Each color card space is provided with a frame-shaped limiting member 12 that fits against the side wall of the color card space. One side of the frame-shaped limiting member 12 is in contact with the color card 5, and the other side of the frame-shaped limiting member 12 is in contact with the cover plate 3.

[0037] The frame-shaped limiting member 12 can fill the excess space in the color card space, thereby holding the color card 5 and preventing the color card 5 from sliding in the color card space.

[0038] One of the cover plates 3 is provided with at least two countersunk holes, and the other cover plate 3 is provided with at least two threaded portions corresponding to the countersunk holes. The rectangular base plate 1 is provided with a through mounting hole 13 corresponding to the countersunk holes. Each countersunk hole is provided with a mounting bolt 14 that passes through the through mounting hole 13 and connects to the threaded portion.

[0039] Loosen the mounting bolts 14 to remove the two cover plates 3, thereby replacing the color card 5 in the color card space or placing the color card 5 into the empty color card space, and then covering the corresponding receiving space with a pair of cover plates 3, and fixing the pair of cover plates 3 to the rectangular base plate 1 with the mounting bolts 14.

[0040] It also includes elastic rings for fitting onto several rectangular base plates 1 after folding.

[0041] The elastic ring is a mature existing technology, so it is not shown in the figure. After the elastic ring is put on, several rectangular base plates 1 can be kept in a folded state.

[0042] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0043] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0044] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
