Description

Technical Field

[0001] This utility model relates to the field of colorimetric card technology, specifically a colorimetric card with a novel structure. Background Technology

[0002] A colorimetric chart is a tool that uses standardized color samples to achieve visual color comparison and quantitative evaluation. In operation, it transforms abstract color differences into referable standards, enabling objective color comparison. It is widely used in the fields of architecture, industry, and home decoration. For example, Chinese patent application number 201922340630.4, filed on 2019-12-24, describes a high-end colorimetric chart in a booklet with sample markings. This provides a convenient way to compare colors with samples and allows users to visually perceive the influence of sample information fonts when flipping through the color samples. Another example is Chinese patent application number 201922340912.4, also filed on 2019-12-24, which describes a high-end colorimetric chart in a booklet with a protective sleeve. During use, magnets help lock the protective sleeve in place, providing comprehensive and effective protection for the color chart booklet during storage, preventing cracking and damage from prolonged careless placement in workshops or environments.

[0003] In the home decoration industry, color matching cards need to be carried around when used. However, the color matching cards mentioned above may become scattered when carried, which is inconvenient for users. In addition, the magnets inside the protective case may attract other objects inside the bag, which will also affect the actual operation of the staff.

[0004] Therefore, we propose a new type of colorimetric card to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a novel colorimetric card structure to solve the problems mentioned in the background art, such as the possibility of the card becoming scattered when carried, making it inconvenient for users to carry, and the possibility that the magnet inside the protective cover may attract other objects inside the bag, which may also affect the actual operation of the staff.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel colorimetric card, comprising a protective outer frame, a connecting shaft fixedly connected to the inner wall of the protective outer frame, and comparison cards equally spaced on the surface of the connecting shaft, and a partition fixedly connected to the surface of the connecting shaft, with the inner wall of the partition fitting against the surface of the outermost comparison card; a guide plate fixedly connected to the outer wall of the protective outer frame, and a movable rod slidably disposed on the surface of the guide plate, with a limit rod fixedly connected to the surface of the movable rod; an outer connecting plate fixedly connected to the outer wall of the protective outer frame, and a locking block slidably disposed inside the outer connecting plate.

[0007] Preferably, the guide plate is shaped like an inverted "U" when viewed from above, and the guide plates are symmetrically distributed on both sides of the protective outer frame, and a second spring is fixedly connected to the inner wall of the guide plate.

[0008] Preferably, the other side of the second spring is fixedly connected to the surface of the movable rod, and the second spring is initially in a compressed state. The lower surface of the movable rod is provided with a slot corresponding to the locking block. Initially, the second spring is in a compressed state. After the end of the locking block moves out of the slot, the second spring can quickly push the movable rod, causing the movable rod to move to the right side of the protective frame.

[0009] Preferably, the card block is initially located inside the card slot, and the length of the limiting rod is greater than the length of the connecting shaft. Since the length of the limiting rod is greater than the length of the connecting shaft, the limiting rod can press down on each comparison card, resulting in high working efficiency.

[0010] Preferably, an external rod is fixedly connected to the outer wall of the protective frame, and the outer rod is fitted with the locking block. The right side surface of the locking block is inclined, and the left side of the outer rod is an inverted "L" structure. When the inclined surface of the locking block is pushed, the locking block will slide on the surface of the outer rod.

[0011] Preferably, a positioning block corresponding to the movable rod is fixedly connected to the inner wall of the guide plate. The positioning block plays an auxiliary positioning role, which simplifies the working process of the locking block, the locking groove and the movable rod, and improves work efficiency.

[0012] Preferably, the card block has a deep groove inside, and a first spring is fixedly connected to the inner wall of the card block. The other side of the first spring is fixedly connected to the inner wall of the external rod. When the card block and the slot are in the same vertical direction, the card block will move back under the action of the first spring. Finally, the end of the card block will enter the inside of the slot. At this time, the movable rod is engaged with the protective outer frame through the card block and the slot.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This novel colorimetric card adopts a novel structural design. Through a movable limiting rod, the comparison card can be quickly pressed down when not in use, preventing it from rotating and spreading out, thus facilitating its carrying and improving flexibility. Simultaneously, the limiting rod can also quickly release the pressure, allowing for flexible use of the comparison card and high work efficiency. Furthermore, it can cover the first and second springs, preventing them from contacting data cables or other objects inside the carrying bag during operation, thus preventing tangling and greatly improving portability. The specific details are as follows:

[0014] (1) In the initial stage of the colorimetric card of the new structure, the end of the card block is located inside the card slot. At this time, the movable rod and the limiting rod remain stable. When it is necessary to hold the comparison card and make the comparison card stable, the card block can be pulled to move the lower surface of the card block out of the card slot. At this time, the movable rod and the limiting rod are not engaged with the protective frame. Then, under the action of the second spring, the limiting rod moves to the right side of the protective frame. Finally, the limiting rod presses down on the comparison card so that the comparison card will not scatter, thus making it convenient for the user to carry.

[0015] Furthermore, a protective cloth can be fitted between the second spring and the movable rod to keep the second spring from contacting the outside world, thus preventing the second spring from getting tangled with objects such as data cables, greatly improving the user experience.

[0016] Furthermore, as the movable rod and the limiting rod move, they slide on the surface of the guide plate. The top view of the guide plate is an inverted "U" shape, which limits the movement distance of the movable rod and the limiting rod, ensuring stability.

[0017] (2) After the user arrives at the work site, the movable rod can be pulled to the left side of the protective frame of the colorimetric card with the new structure. After the lower surface of the movable rod contacts the card block, the movable rod will push the inclined surface of the card block. At this time, the card block slides on the surface of the outer rod and the card block will squeeze the first spring. When the card block and the card slot are in the same vertical direction, the card block will move back under the action of the first spring. Finally, the end of the card block will enter the inside of the card slot. At this time, the movable rod is engaged with the protective frame through the card block and the card slot. Then the movable rod and the limiting rod return to their original positions, so that the colorimetric card is not compressed. At this time, the colorimetric card can be used normally. The workflow is simple and quick and the work efficiency is high.

[0018] Furthermore, during the movement of the movable rod, it will contact the positioning block on the inner wall of the guide plate. After the movable rod contacts the positioning block, the locking block and the locking slot are exactly in the same vertical direction. The positioning block plays an auxiliary positioning role, which simplifies the working process of the locking block, the locking slot and the movable rod, and improves work efficiency.

[0019] (3) The first spring of the colorimetric card of the new structure is located inside the external rod and will not come into contact with other objects inside the carrying bag, thus preventing entanglement and greatly improving the portability of the protective frame and the colorimetric card.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-6 The present invention provides the following technical solution: a novel colorimetric card.

[0029] Example 1: By using the movable rod 5 and the limiting rod 6, the comparison card 3 can be pressed down when carrying the protective outer frame 1, preventing the comparison card 3 from rotating and spreading out on the connecting shaft 2, thus improving the portability of carrying the comparison card 3. Figures 1-5As shown, the device includes a protective outer frame 1, a connecting shaft 2 fixedly connected to the inner wall of the protective outer frame 1, and comparison cards 3 are sleeved and connected at equal intervals on the surface of the connecting shaft 2, and a partition 7 is fixedly connected to the surface of the connecting shaft 2, while the inner wall of the partition 7 is in contact with the surface of the outermost comparison card 3; a guide plate 4 is fixedly connected to the outer wall of the protective outer frame 1, and a movable rod 5 is slidably arranged on the surface of the guide plate 4, and a limit rod 6 is fixedly connected to the surface of the movable rod 5; an outer connecting plate 9 is fixedly connected to the outer wall of the protective outer frame 1, and a locking block 10 is slidably arranged inside the outer connecting plate 9.

[0030] The top view of the guide plate 4 is an inverted "U" shape, and the guide plate 4 is symmetrically distributed on both sides of the protective outer frame 1. A second spring 14 is fixedly connected to the inner wall of the guide plate 4. The other side of the second spring 14 is fixedly connected to the surface of the movable rod 5. The second spring 14 is initially in a compressed state. The lower surface of the movable rod 5 is provided with a slot 8 corresponding to the locking block 10. The locking block 10 is initially located inside the slot 8. The length of the limiting rod 6 is greater than the length of the connecting shaft 2.

[0031] Initially, the end of the locking block 10 is located inside the slot 8. At this time, the movable rod 5 and the limiting rod 6 remain stable inside the protective outer frame 1. When it is necessary to hold the comparison card 3 in place and stabilize it, the locking block 10 can be pulled, causing it to slide inside the outer plate 9. Eventually, the lower surface of the locking block 10 moves out of the slot 8. At this time, the movable rod 5 and the limiting rod 6 are not engaged with the protective outer frame 1. Consequently, under the action of the second spring 14, the limiting rod 6 and the movable rod 5 move to the right side of the protective outer frame 1 on the surface of the guide plate 4. The top view of the guide plate 4 is an inverted "U" shape, which limits the movement distance of the movable rod 5 and the limiting rod 6, ensuring stability (e.g., Figure 1 and Figure 3 As shown), the final limiting rod 6 presses down on the comparison card 3, preventing the comparison card 3 from scattering and making it convenient for the user to carry.

[0032] A protective cloth can be placed between the second spring 14 and the movable rod 5 to keep the second spring 14 from contacting the outside world, thus preventing the second spring 14 from getting tangled with objects such as data cables, which greatly improves the user experience.

[0033] Example 2: Unlike Example 1, the first spring 13 allows the locking block 10 to quickly return to the slot 8, disabling the movable rod 5 and the limiting rod 6, preventing the comparison card 3 from being compressed, allowing it to rotate normally on the surface of the connecting shaft 2, and enabling normal use of the comparison card 3. Figure 1 and Figure 6As shown, an external rod 11 is fixedly connected to the outer wall of the protective frame 1, and a locking block 10 is sleeved on the surface of the external rod 11. The right side surface of the locking block 10 is inclined, and the left side of the external rod 11 is an inverted "L" structure. A deep groove is opened inside the locking block 10, and a first spring 13 is fixedly connected to the inner wall of the locking block 10. The other side of the first spring 13 is fixedly connected to the inner wall of the external rod 11.

[0034] After the user arrives at the work site, they can pull the movable rod 5 to the left of the protective outer frame 1, causing the movable rod 5 to slide back on the surface of the guide plate 4. During this process, after the lower surface of the movable rod 5 contacts the locking block 10, the movable rod 5 will push the inclined surface of the locking block 10. At this time, the locking block 10 slides inside the outer plate 9 and also slides downward on the surface of the outer rod 11 (e.g., Figure 6 As shown), at this time, the locking block 10 will squeeze the first spring 13. When the locking block 10 and the locking groove 8 are in the same vertical direction, the locking block 10 will move back under the action of the first spring 13. Finally, the end of the locking block 10 will enter the interior of the locking groove 8. At this time, the movable rod 5 and the limiting rod 6 are engaged with the protective outer frame 1 through the locking block 10 and the locking groove 8. Then the movable rod 5 and the limiting rod 6 return to their original positions, so that the comparison card 3 is not compressed. At this time, the staff and customers can use the comparison card 3 normally. The workflow is simple and quick, and the work efficiency is high.

[0035] The first spring 13 is located inside the outer rod 11 and will not come into contact with other objects inside the carrying bag, thus preventing tangling and mess, which greatly improves the portability of the protective frame 1 and the comparison card 3.

[0036] Example 3: Unlike Example 2, the positioning block 12 serves as an auxiliary positioning element, allowing the locking block 10 and the locking slot 8 to be aligned vertically more quickly, simplifying the docking process and reducing the difficulty of docking. Figure 3 As shown, a positioning block 12 corresponding to the movable rod 5 is fixedly connected to the inner wall of the guide plate 4.

[0037] During the movement of the movable rod 5, it will contact the positioning block 12 on the inner wall of the guide plate 4. After the movable rod 5 contacts the positioning block 12, the locking block 10 and the locking groove 8 are exactly in the same vertical direction. That is, the positioning block 12 plays an auxiliary positioning role, which simplifies the working process of the locking block 10, the locking groove 8 and the movable rod 5, and improves the working efficiency (e.g., Figure 3 (As shown).

[0038] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
