Description

Technical Field

[0001] The present invention relates to the technical field of straight rulers, and specifically to an auxiliary cutting multifunctional straight ruler. Background Art

[0002] A straight ruler is an indispensable tool in scribing and cutting operations. However, traditional straight rulers have the following significant defects when dealing with high-precision cutting requirements:

[0003] Insufficient cutting accuracy: Due to the thickness difference between the cutting edge and the blade body of the cutting tool (the inclination of the cutting edge caused by the tool design), when the blade body is close to the edge of the straight ruler during cutting, the cutting edge cannot vertically cut into the material, and the actual cutting line will deviate from the theoretical scribing position, resulting in error accumulation. Lack of a dynamic compensation mechanism and relying on manual experience adjustment, it is difficult to meet the millimeter-level accuracy requirements.

[0004] Poor fixing stability: The anti-slip of traditional straight rulers relies on the bottom texture or manual pressing, but it is easy to slide on high-smooth surfaces, resulting in scribing or cutting deviation. In the prior art, the solutions of adding weights or suction cups for fixing are cumbersome to operate and difficult to adapt to different material surfaces.

[0005] Single calibration function: Although some straight rulers integrate a simple scale calibration structure, most of them are of a fixed design and cannot be dynamically adjusted according to the thickness of the cutting tool. Moreover, the calibration components (such as baffles) are prone to wear after long-term use and need to be replaced as a whole, resulting in high maintenance costs.

[0006] Therefore, there is an urgent need for a multifunctional straight ruler tool with intelligent calibration, high-stability fixing, and reusable calibration functions to improve cutting accuracy, operation efficiency, and tool durability. Summary of the Invention

[0007] In view of the deficiencies of the prior art, the present invention provides an auxiliary cutting multifunctional straight ruler, which solves the problems mentioned above.

[0008] To achieve the above objectives, the present invention is realized through the following technical solutions: An auxiliary cutting multifunctional straight ruler includes a straight ruler body, a scribing end and a cutting end respectively arranged on both sides of the straight ruler body in the length direction. A scribing scale is arranged above the scribing end. A pressing component for increasing the friction between the straight ruler body and the placement table is arranged inside the straight ruler body. A calibration component for calibrating the distance of cutting is arranged on the side of the straight ruler body;

[0009] The calibration component includes a reference plate slidably arranged on the side of the straight ruler body and an analog plate fixed above the straight ruler body. A positioning structure for positioning with the straight ruler body is arranged on the reference plate;

[0010] The ruler body also includes a hexagonal column that is clamped in a clamping groove in the inner cavity of the ruler body, the simulation plate is arranged on the side of the clamping groove, the six faces of the hexagonal column are all cutting faces for the cutting knife to simulate cutting, the surfaces of the six cutting faces are all provided with calibration scales, the surface of the reference plate is provided with adjustment scales, and the side of the ruler body is provided with a reference positioning line located on the side of the adjustment scale. When the material needs to be cut after marking during use, because the cutting knife has a certain thickness above the blade in order to ensure the cutting effect, if the side of the knife abuts against the ruler body during cutting, the blade cannot contact the material in a vertical state, and errors are prone to occur when high-precision cutting is required. By using the cutter to simulate cutting on the hexagonal column in the card slot, using the simulation board to simulate the cutting end as the surface for the blade to abut, and then after the blade passes through the cutting surface of the hexagonal column surface, the deviation between the blade and the bottom of the simulation board is measured by the calibration scale on the cutting surface, and then the positioning rod on the side of the reference plate is pulled out from the positioning hole, and then the reference plate is pressed, the ruler body is slid to adjust the position, and the reference positioning line and the adjustment scale are used for positioning, and the ruler body is moved back by the distance measured by the calibration scale. At this time, the calibration is completed, and the ruler body is positioned by pressing the cutting baffle, and then cutting is performed through the cutting end. The thickness of the cutter can be automatically calibrated to ensure the accuracy of cutting.

[0011] As a further solution of the present invention: the positioning structure includes a sleeve fixed above the reference plate, the inner cavity of the sleeve is slidably connected with a positioning rod, and the inner cavity of the ruler body is provided with a positioning hole that is inserted into the positioning rod when the reference positioning line is aligned with the initial point of the adjustment scale.

[0012] As a further solution of the present invention: both ends of the hexagonal prism are regular hexahedrons, and the six faces of the hexagonal prism are used for cutting simulation by a cutting knife, and when one face cannot be simulated, the hexagonal prism can be pulled out and replaced with another face for repeated use.

[0013] As a further solution of the present invention: a damper is arranged between the reference plate and the ruler body, and the damper can prevent the reference plate from sliding randomly, and the reference plate will move only after being subjected to a sufficiently large force, which is more stable.

[0014] As a further solution of the present invention: an anti-skid pad is fixedly connected to the bottom of the ruler body, so that the ruler body is in contact with the table surface more stably through the anti-skid pad.

[0015] As a further solution of the present invention: a cutting baffle is fixedly connected to the upper part of the ruler body, and the cutting baffle can be pressed by hand to apply force to the upper part of the ruler body, so that the ruler body can be effectively fixed.

[0016] As a further solution of the present invention: the pressing assembly includes two pressing blocks movably arranged at the bottom of the inner cavity of the ruler body, a needle net is provided at the bottom of the pressing block, a connecting rod is fixedly connected to the top of the pressing block and passes through and extends to the top of the ruler body, a pressing plate is fixedly connected to the top of the connecting rod, the two pressing plates are connected by a connecting plate, and the needle net is composed of a plurality of needles evenly arranged at the bottom of the pressing block.

[0017] As a further solution of the present invention: the bottom of the pressing plate is fixedly connected with an elastic pad abutting against the top of the ruler body. When it is needed to mark or cut a relatively smooth material during use, the ruler body directly placed on top is prone to slipping and cannot be effectively fixed. At this time, the connecting plate is pressed to apply force to the pressing block, so that the needle net abuts against the material surface, and the needle heads of the needle net are lower than one end of the ruler body and slightly embedded in the material surface, thereby fixing the ruler body, which can effectively prevent its circumferential sliding. The elastic pad is used to apply pressure to the ruler body so that it can be tightly squeezed on the material surface. Even when facing smooth materials, it can be firmly fixed without causing damage to the material surface. Moreover, whether to press with the needle net can be freely switched by choosing whether to press the connecting plate. The operation is convenient and simple to use.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] High-precision dynamic calibration system:

[0020] Hexagonal prism multi-faceted calibration: The six cutting surfaces of the hexagonal prism are all equipped with calibration scales. By simulating the cutting action to quantify the tool thickness deviation, combined with the adjustment scale of the reference plate and the linkage with the reference positioning line, the automatic compensation of the ruler body backward movement Δ distance is realized, eliminating the cutting path deviation caused by tool tilt, with an accuracy of up to ±0.5mm.

[0021] Recyclable design: When one side of the hexagonal column is worn, it can be rotated to switch to a new side, extending the service life and reducing maintenance costs.

[0022] Multi-Mode Anti-Slip Retention System:

[0023] Needle mesh micro-embedded fixation: The pressing component micro-punctures the material surface through the dense needles of the needle mesh, and forms a "lattice anchor" combined with the elastic pressure of the elastic pad. It is suitable for high-smooth surfaces, improves the anti-slip force by more than 60%, and avoids surface scratches.

[0024] Dual-mode free switching: In normal mode, it relies on the anti-slip texture on the bottom to fix it. When high stability is required, press down the connecting plate to activate the needle net, which is suitable for different material hardness and operation scenarios.

[0025] Convenient operation and enhanced stability:

[0026] Quick locking and release: The plug-in design of the positioning rod and the positioning hole enables one-key locking of the initial position of the reference plate. Together with the damping structure, it prevents accidental displacement after calibration and ensures operation stability.

[0027] Optimization of single-handed operation: The cutting baffle integrates a force application point, and the straight ruler can be fixed by pressing with one hand, improving operation efficiency.

[0028] Modular and durability design:

[0029] Replaceable hexagonal post: The clamping groove and the hexagonal post adopt a standardized interface, which is convenient for quick replacement or reverse use, reducing the tool loss rate.

[0030] Anti-wear structure: The simulation plate and the cutting end are hardened to reduce wear caused by tool friction and extend the life of the core components. Description of the drawings

[0037] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in conjunction with the drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects of the present invention as follows.

[0038] Please refer to Figures 1-5, the present invention provides a technical solution: an auxiliary cutting multi-functional straightedge, including a straightedge body 1, a scribing end 11 and a cutting end 12 respectively arranged on both sides of the straightedge body 1 in the length direction. There is a gap between the outer edge of the scribing end 11 of the straightedge and the surface of the measured object, avoiding the phenomenon that the pen ink seeps onto the measured object and causes the drawn straight line to have a trailing tail, which affects the scribing effect; the cutting end 12 is provided with a guard plate to avoid the harm caused by the jumping knife to the measurer during cutting; the bottom of the straightedge is provided with an anti-slip pad 17, and at the same time, the bottom of the cutting end 12 is provided with a toothed anti-slip strip, and the toothed anti-slip strip cooperates with the anti-slip pad 17 to achieve a dual anti-slip effect, so as to be suitable for the anti-slip of the surfaces of more items. A scribing scale is arranged above the scribing end 11. A pressing component for increasing the friction between the straightedge body 1 and the placement tabletop is arranged inside the straightedge body 1. A calibration component for calibrating the distance of cutting is arranged on the side of the straightedge body 1;

[0039] The calibration component includes a reference plate 33 slidably arranged on the side of the straightedge body 1 and a simulation plate 14 fixed above the straightedge body 1. A positioning structure for positioning with the straightedge body 1 is arranged on the reference plate 33;

[0040] It also includes a hexagonal column 31 clamped in the clamping groove 13 inside the straightedge body 1. The simulation plate 14 is arranged on the side of the clamping groove 13. The six surfaces of the hexagonal column 31 are all cutting surfaces for the cutting knife to perform simulated cutting. Calibration scales 32 are arranged on the surfaces of the six cutting surfaces. An adjustment scale 36 is arranged on the surface of the reference plate 33. A reference positioning line 16 is opened on the side of the straightedge body 1 on the side of the adjustment scale 36. When it is necessary to perform cutting after scribing the material during use, because in order to ensure the cutting effect, there is a certain thickness above the cutting edge of the cutting knife. If the side of the knife abuts against the straightedge body 1 during cutting, the cutting edge cannot contact the material in a vertical state. When high-precision cutting is required, errors are likely to occur. At this time, by using the cutting knife to perform simulated cutting on the hexagonal column 31 in the clamping groove 13, the simulation plate 14 is used to imitate the cutting end 12 as the surface where the cutting edge abuts. Then, after the cutting edge passes over the cutting surface of the hexagonal column 31, the deviation between the cutting edge and the bottom of the simulation plate 14 is measured through the calibration scale 32 on the surface of the cutting surface. Then, the positioning rod 35 on the side of the reference plate 33 is pulled out of the positioning hole, and then the reference plate 33 is pressed, and the straightedge body 1 is slid to adjust the position. Positioning is performed through the reference positioning line 16 and the adjustment scale 36, and the straightedge body 1 is moved backward by the distance measured through the calibration scale 32. At this time, the calibration is completed. The straightedge body 1 is positioned by pressing the cutting baffle 15, and then cutting is performed through the cutting end 12, which can automatically calibrate according to the thickness of the cutting knife and ensure the accuracy during cutting.

[0041] The positioning structure includes a sleeve 34 fixed above the reference plate 33. A positioning rod 35 is slidably connected inside the sleeve 34. A positioning hole is provided inside the straight ruler body 1, which is used to insert the positioning rod 35 when the reference positioning line 16 aligns with the initial point of the adjustment scale 36.

[0042] Both ends of the hexagonal column 31 are regular hexahedrons. The six faces of the hexagonal column 31 are used for the cutting simulation by the cutting knife. After one face cannot be simulated, the hexagonal column 31 can be taken out and replaced with another face for repeated use.

[0043] A damping is provided between the reference plate 33 and the straight ruler body 1. Through the setting of the damping, the reference plate 33 can be prevented from sliding randomly and will move only after receiving a sufficiently large force, making it more stable.

[0044] The bottom of the straight ruler body 1 is fixedly connected with an anti-slip pad 17, which makes the contact with the tabletop more stable through the anti-slip pad 17.

[0045] A cutting baffle 15 is fixedly connected above the straight ruler body 1. By pressing the cutting baffle 15 by hand to apply force above the straight ruler body 1, it can be effectively fixed. And through the cutting baffle 15, the injury to the measurer caused by the jumping of the cutting knife during cutting is avoided.

[0046] The pressing assembly includes two pressing blocks 24 movably arranged at the bottom inside the straight ruler body 1. A needle net 25 is provided at the bottom of the pressing block 24. The top of the pressing block 24 is fixedly connected with a connecting rod 23 that penetrates and extends above the straight ruler body 1. The top of the connecting rod 23 is fixedly connected with a pressing plate 21. The two pressing plates 21 are connected by a connecting plate 22. The needle net 25 is composed of a plurality of needles evenly arranged at the bottom of the pressing block 24.

[0047] An elastic cushion plate 26 that abuts against the top of the straight ruler body 1 is fixedly connected to the bottom of the pressing plate 21. When in use, when it is necessary to draw lines or cut relatively smooth materials, at this time, if the straight ruler body 1 is directly placed on it, it is easy to slip and cannot be effectively fixed. At this time, by pressing the connecting plate 22 to apply force to the pressing block 24, the needle net 25 is made to abut against the material surface. The needles of the needle net 25 are slightly embedded in the material surface at one end lower than the straight ruler body 1 to fix the straight ruler body 1, which can effectively prevent its circumferential sliding. And through the setting of the elastic cushion plate 26, pressure is applied to the straight ruler body 1 so that it can also be firmly pressed against the material surface. Even when facing smooth materials, it can be firmly fixed and will not cause damage to the material surface. Moreover, it is possible to freely switch whether to press with the needle net 25 by choosing whether to press the connecting plate 22, with convenient operation and simple use.

[0048] When the present invention is in use,

[0049] 1. Working process of the calibration system

[0050] Step 1: Simulated cutting and deviation measurement

[0051] Press the cutting knife against the simulation board 14 and perform simulated cutting along the cutting surface of the hexagonal column 31. After the cutting edge contacts the cutting surface, directly read the deviation value Δ between the actual contact point of the cutting edge and the bottom of the simulation board 14 through the calibration scale 32, which is the path offset caused by the tool thickness.

[0052] Step 2: Dynamic compensation adjustment

[0053] Pull out the positioning rod 35, hold the reference board 33 and slide the ruler body 1 so that the reference positioning line 16 aligns with the Δ scale position of the adjustment scale 36. The ruler body 1 moves backward by a distance of Δ synchronously to achieve precise compensation of the cutting path.

[0054] Step 3: Locking and performing cutting

[0055] After calibration, re-insert the positioning rod 35 to fix the reference board 33, press the cutting baffle 15 to activate the anti-slip system, and perform vertical cutting along the cutting end 12 to ensure that the cutting edge coincides with the theoretical marking line.

[0056] 2. Working process of the pressing and fixing system

[0057] High anti-slip mode:

[0058] Press down the connecting plate 22 → drive the pressing block 24 to move downward → the needles of the needle net 25 penetrate into the surface of the material, and the elastic cushion 26 is compressed to generate a reverse elastic force → form a double fixation of "needle embedding + elastic pressing" to resist the lateral shear force during cutting.

[0059] Ordinary anti-slip mode:

[0060] Release the connecting plate 22 → the elastic cushion 26 rebounds to drive the needle net 25 to rise → the ruler only contacts the material through the anti-slip lines at the bottom, which is suitable for regular marking or cutting of soft materials.

[0061] 3. Multi-scenario adaptation logic

[0062] High-precision cutting scenario: Enable the calibration component + needle net fixation mode, suitable for smooth materials;

[0063] Fast marking scenario: Only use the initial positioning of the reference board 33 + anti-slip line fixation to improve operation efficiency;

[0064] Repeated calibration requirement: Rotate or replace the surface of the hexagonal column 31 to meet the calibration requirements after multi-tool switching or long-term use.

Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments of equivalent changes within the scope of the technical solution of the present invention by using the technical content disclosed above.
