Description

Technical Field

[0001] This utility model belongs to the field of office supplies technology, specifically, it relates to a multifunctional mat. Background Technology

[0002] In daily office settings, writing pads are frequently used auxiliary tools, with their core functions being to provide flat support for writing and desktop protection for paper cutting. Their completeness of function and ease of use directly affect office efficiency. As office needs become more refined and diversified, the shortcomings of traditional writing pads—"single function and poor adaptability"—are becoming increasingly apparent, and existing improvement solutions have failed to fully cover actual needs.

[0003] Currently, there have been attempts in the industry to optimize traditional stamping pads, such as the "Multifunctional Office Pad" patent number CN206968211U. This patent attempts to solve the problems of "lack of positioning when stamping and easy paper shifting" by setting a fixed stamp groove and a sliding paper limiting strip on the substrate: its stamp groove can initially limit the stamp, preventing it from sliding randomly when stamping; the limiting strip can be adjusted by sliding to adapt to paper of different widths, achieving basic fixation. However, this solution still has the following defects in practical applications and needs improvement: Firstly, the stamp slot adopts a fixed size and fixed position design, which can only be adapted to specific sizes of stamps (such as round official seals), and the stamping position is limited to the preset area of ​​the base plate. When facing oval contract stamps, small-sized personal name stamps, or when it is necessary to stamp in different positions such as the corners or center of the paper, it cannot be flexibly adjusted, and the adaptability is seriously insufficient. Secondly, the paper is fixed by sliding limit strips on one or both sides. The contact area between the limit strip and the paper is small. For thin paper (such as tracing paper and note paper) or irregularly shaped paper (such as labels and business cards), the problem of "edge lifting and loose fixation" is likely to occur. In addition, the sliding track of the limit strip is prone to dust accumulation and jamming after long-term use, which affects the fixation stability. Third, the solution does not integrate a cutting function. When users need to cut paper, they need to add a separate cutting mat and cutting blade, which not only increases the cost of carrying and storing tools, but also lacks a dedicated desktop protection structure, which can easily lead to scratches on the desktop. Fourth, the positioning accuracy relies solely on the printed scale lines on the substrate surface, without any auxiliary positioning components. When multiple sheets of paper need to be aligned to the same size (such as aligning the edges of multiple pages of documents and uniformly reserving binding edges), manual alignment is required repeatedly. This operation is cumbersome and the accuracy is difficult to guarantee, especially when processing documents in batches, resulting in low efficiency.

[0004] In addition, CN206968211U has insufficient structural stability and functional synergy: its stamp slot and substrate are separate splicing structures, which are prone to loosening and displacement after long-term use, resulting in a decrease in stamping accuracy; the limiting strip and stamp slot are functionally independent and lack linkage design, making it impossible to achieve a continuous operation of "positioning-fixing-stamping".

[0015] In a preferred embodiment: the size and area of ​​the cover plate are larger than the size and area of ​​the base plate; the magnetic plate has a pad groove near the four corners of the covering surface facing the cover plate, and a silicone pad is placed in the pad groove; a cutting pad is provided on the end face of the magnetic plate away from the cover plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model uses a linkage positioning structure where the cover plate connects to the insert plate and the loose-leaf slot, and the bottom plate connects to the loose-leaf positioning block. This structure can precisely limit the relative displacement of the stamp, prevent stamping deviation, and ensure that the cover plate is evenly stressed, thus guaranteeing a clear and complete stamp surface. At the same time, the stamp has no fixed size or shape restrictions and can be customized according to office needs. The stamping position can be flexibly adjusted according to the paper positioning, solving the defects of existing technologies where the fixed stamp slot can only accommodate a single stamp and the stamping position is limited. This invention is suitable for various office stamping scenarios.

[0017] 2. The base plate cover of this utility model has a scale that is combined with a movable magnetic ruler, which can quickly align the edges of paper and calibrate the size of multiple pages of documents without the need for repeated manual alignment, thus improving positioning accuracy and batch processing efficiency. The magnet that can be attracted to the magnetic plate can adjust its position according to the size and thickness of the paper, increasing the stability of contact with the paper and preventing the edges of thin paper from curling up or irregularly shaped paper from becoming loose. This solves the problem of small contact area and easy dust accumulation and jamming of existing sliding limit strips, and is suitable for fixing various types of paper.

[0018] 3. This utility model features a cutting pad on the base plate away from the cover plate, eliminating the need for a separate cutting pad and utility knife. Paper can be cut directly using this pad, which can also be used for drawing. This integrates four functions: writing support, stamp positioning, paper cutting, and drawing. All functions can be operated seamlessly without frequent tool switching or paper position adjustments, simplifying office workflows, reducing tool carrying and storage costs, and improving desktop space utilization and office efficiency.

[0019] 4. The cover plate and hinges of this utility model are fixed by rivets, and the base plate and hinges are engaged by positioning blocks. Both are rigid connections, avoiding the problem of easy loosening and displacement of existing split splicing structures. The silicone pads at the four corners of the base plate form friction limits when the cover plate is closed, further preventing slippage and improving structural durability. The cover plate can rotate 180° with the base plate through the hinges to adapt to different working postures. The cover plate is larger than the base plate and can be fully closed. When stored, it protects the magnetic ruler, magnets and stamps, reducing the risk of component loss. When not in use, it occupies little space and is easy to carry and store.

[0020] Other features, objects, and advantages of this invention will become more apparent from the following detailed description of non-limiting embodiments with reference to the accompanying drawings: Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is an exploded view of the structure of this utility model; Figure 3 This is a schematic diagram of the structure of the loose-leaf mechanism of this utility model.

[0021] The following are the labeling elements in the figure: Detailed Implementation

[0022] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention.

The upper sleeve plate 21 has a stepped recessed groove 25, and two positioning blocks 26 are provided at the bottom of the recessed groove 25. When the cover plate 1 and the hinge 2 are installed, the connecting sleeve plate 33 on the cover plate 1 is embedded in the recessed groove 25, and the two positioning blocks 26 at the bottom of the recessed groove 25 are respectively embedded in the limiting hole 34 on the connecting sleeve plate 33. Each positioning block 26 is interference-fitted with the matching limiting hole 34 to realize the positioning and installation of the cover plate 1 and the hinge 2. The bottom of the lower sleeve plate 22 is provided with a groove 23. The connecting plate 8 on the magnetic suction plate 31 is inserted into the groove 23, and the groove 23 achieves the initial positioning of the lower sleeve plate 22 and the magnetic suction plate 31. The side of the lower sleeve plate 22 is provided with a fixing hole 24. When the connecting plate 8 on the magnetic suction plate 31 is inserted into the groove 23, the fixing hole 24 coincides with the positioning hole 9.

[0039] Working principle When this utility model is in use, the cover plate 1 is flipped open from the base plate 3 by the rotational cooperation of the upper sleeve plate 21 and the lower sleeve plate 22 of the hinge 2. The opening angle can be adjusted by 180 degrees according to the operation requirements. Then, place the work paper on the cover surface of the base plate 3, move the magnetic ruler 5, and align the paper edge with the scale on the cover surface to accurately position the paper; after positioning, attach the two magnets 6 to the opposite corners of the paper, and fix the paper in place by the attraction between the magnets 6 and the magnetic suction plate 31 to prevent the paper from moving. At this point, the magnetic plate 31 of the base plate 3 can provide flat support, allowing writing to be done directly on the fixed paper; if it is necessary to cut the paper, move the paper to the surface of the cutting pad 35, use the cutting pad 35 as support, and use tools such as a utility knife to cut it. The cutting pad 35 can protect the desktop and the magnetic plate 31, while preventing damage to the blade; the cutting pad 35 can also be used directly for drawing to meet the needs of sketching. Next, after fixing the paper to be stamped on the mating surface of the base plate 3, rotate the cover plate 1 so that the cover plate 1 is closed on top of the base plate 3; during the closing process, the connecting insert plate 8 is inserted into the groove 23 of the upper sleeve plate 21, and the limiting hole 34 of the connecting sleeve plate 33 is engaged with the positioning block 26 to achieve precise positioning of the cover plate 1 and the base plate 3; after the cover plate 1 is closed, the stamp 4 in the middle of the mating surface of the cover plate 1 is exactly aligned with the position of the paper to be stamped. Press the cover plate 1, and the pressure of the cover plate 1 makes the stamp 4 evenly stressed, so that the text or pattern on the stamp 4 is evenly stamped on the paper; when closing, the silicone pad 7 in the pad groove 32 of the base plate 3 contacts the cover plate 1, and the friction of the silicone pad 7 restricts the relative displacement between the cover plate 1 and the base plate 3, ensuring the stability of the position during the stamping process; Finally, after completing the task, remove magnet 6 and magnetic ruler 5 and temporarily store them on the edge of base plate 3. Remove the paper from base plate 3, then rotate cover plate 1 so that cover plate 1 completely covers the top of base plate 3 to complete the storage and reduce the space occupied.
