Also, the term "upper" may also be used in some cases to indicate a certain attachment relationship or connection relationship. For those skilled in the art, the specific meaning of these terms in the present application can be understood according to the specific circumstances.
[0029] Please refer to Figure 1 - Figure 6 The utility model provides a technical scheme:
[0030] A woodworking drawing multifunctional combination square, comprising a ruler plate 1, in addition, the ruler plate 1 is provided with millimeter scale numbers and inch scale numbers on both sides, the ruler plate 1 is used as a basic component, millimeter scale numbers are accurately engraved on both sides thereof, the range reaches 30 centimeters, and inch scale numbers are also provided, and the range is 12 inches, and this design can facilitate the switching of inch and metric scales for users in different countries.
[0031] In an embodiment of the utility model, the ruler plate 1 is provided with a measuring assembly 2, the measuring assembly 2 comprises a rectangular groove 21, the rectangular groove 21 is formed on both sides of the ruler plate 1, a through sliding groove 22 is formed in the center of the ruler plate 1, the rectangular groove 21 is communicated with the sliding groove 22, a ruler seat 23 is slidably attached to the ruler plate 1, in addition, the rectangular groove 21 is provided with two groups, and the two groups of rectangular grooves 21 are located at both ends of the ruler plate 1, so that the ruler seat 23 is more stable when moving, a convex strip 24 is arranged on the ruler seat 23, the convex strip 24 is slidably attached to the inside of the rectangular groove 21, a through hole 25 is formed in the ruler seat 23, a screw 26 is sleeved in the through hole 25, one end of the screw 26 is fixedly connected to the outer wall center of a thin plate 27, the thin plate 27 is slidably attached to the inside of the rectangular groove 21, a nut 28 is threadedly mounted on the other end of the screw 26, in addition, the ruler plate 1, the ruler seat 23, the convex strip 24, the screw 26, the thin plate 27 and the nut 28 are all made of aluminum alloy, so that compared with traditional materials, they can better resist wear and deformation, the ruler seat 23 is located between the ruler plate 1 and the nut 28, the screw 26 penetrates through the sliding groove 22, and the two sides of one end of the ruler seat 23 close to the through hole 25 are respectively provided with a 90-degree included angle 29 and a 135-degree included angle 210.
[0032] In this embodiment, the rectangular groove 21 provides a track for the movement of subsequent components. The ruler base 23, as a key moving component, has its bottom protrusion 24 precisely embedded inside the rectangular groove 21. This close-fitting design ensures both smooth movement of the ruler base 23 and stability during movement. The thin plate 27 also slides within the rectangular groove 21, providing balance and auxiliary support when the screw 26 moves. When users face different woodworking scenarios and need to flexibly adjust the position of the ruler base 23 on the ruler board 1, the first step is to loosen the nut 28. As screw 26 gradually loosens, the tightening force between the screw 26 and the ruler base 23, which were originally tightly fixed, decreases. At this point, the ruler base 23 and its bottom protrusion 24, no longer experiencing significant resistance, can slide laterally on the rectangular groove 21 of the ruler plate 1. During the movement of the ruler base 23, the screw 26, which passes through the slide groove 22, also moves synchronously within the slide groove 22. Simultaneously, the thin plate 27, connected to one end of the screw 26, also slides synchronously on the rectangular groove 21, its sliding trajectory consistent with the moving direction of the ruler base 23, playing a role in auxiliary stabilization. This multi-component coordination... The movable design ensures that the relative positions of all components remain coordinated during adjustment, preventing jamming or misalignment. After the aforementioned adjustment steps, once the ruler base 23 has moved to the target position that meets the user's needs, the user needs to tighten the nut 28 again. As the nut 28 is tightened, the screw 26 gradually moves towards the ruler base 23 under the action of the threads, thereby generating a fastening force on the ruler base 23. This fastening force makes the ruler base 23 fit tightly against the ruler plate 1, and the current relative position of the ruler plate 1 and the ruler base 23 is thus firmly locked. All components are made of aluminum alloy, which not only has good strength, but also has excellent resistance to deformation when subjected to external impact, ensuring that the relative position between the ruler base 23 and the ruler plate 1 does not change, thus ensuring that the measurement accuracy of the square is not affected. Whether in daily woodworking marking, drawing, or adjusting woodworking machinery (such as woodworking bench drills and woodworking saws), this stable position locking function can provide users with reliable accuracy assurance. It is worth noting that when the outer wall of the ruler plate 1 is close to the target surface, the outer wall of the ruler base 23 is also close to the target surface.
[0033] Further, after the position locking of the ruler seat 23 is completed, the 90-degree angle 29 and the 135-degree angle 210 on the ruler seat 23 begin to play an important role, and when angle measurement is performed, the user only needs to align the corresponding angle of the angle ruler with the angle edge to be measured, for example, when a right angle needs to be measured, the 90-degree angle 29 is attached to the two sides of the right angle, and by observing the attachment of the angle ruler and the measured angle, it can be accurately judged whether the angle is a right angle, and similarly, when a 45-degree angle needs to be measured, the 135-degree angle 210 can be used, and through simple calculation (180 degrees-135 degrees=45 degrees), combined with the attachment of the angle ruler and the measured angle, the 45-degree angle can be accurately measured, and in the actual operation process of woodworking, the role of the angle ruler is particularly significant for the adjustment of the drill bit and the saw blade of the woodworking bench, and the user can obtain intuitive and accurate adjustment data by observing the scale and angle mark on the angle ruler, combined with the positional relationship between the angle ruler and the workpiece or mechanical component, which greatly reduces the difficulty of woodworking operation, improves the work efficiency and precision, and enables the angle ruler to freely switch between various complex use scenarios such as woodworking marking, planar drawing, woodworking machine adjustment, and meets the diversified needs of woodworking in different work links.
[0034] In an embodiment of the present application, the ruler seat 23 is provided with an auxiliary assembly 3, the auxiliary assembly 3 comprises a handle 31, the ruler seat 23 is provided with the handle 31, the handle 31 is inclined, which is convenient for the operator to move the ruler seat 23, in addition, the end of the ruler seat 23 close to the through hole 25 is provided with a through expansion slot 32, which is convenient for subsequent adaptation of various expansion pieces, such as angle fine adjuster, lengthened measuring arm, etc., in addition, the end of the ruler seat 23 away from the through hole 25 is internally fixedly installed with a liquid bubble level 33, and the auxiliary angle ruler body remains in a horizontal position during use.
[0035] When the embodiment is used, the inclination angle of the handle 31 is ergonomic, aiming to provide the most comfortable and convenient holding experience for the operator, when the operator needs to move the ruler seat 23, only needs to hold the handle 31, due to the inclined design of the handle 31, the operator can more easily transmit the force to the ruler seat 23 when exerting force, thereby conveniently pushing the ruler seat 23 to move on the ruler plate 1, the expansion slot 32 provides infinite possibilities for the functional expansion of the angle ruler, through the expansion slot 32, the user can adapt various types of expansion pieces according to actual work requirements, for example, when more accurate fine adjustment of the angle is needed, an angle fine adjuster can be installed, the angle fine adjuster can fine adjust the angle of the ruler seat 23 within a certain range through the connection with the expansion slot 32, further improving the accuracy of the angle ruler in angle measurement and adjustment, for example, when long distance measurement is performed, a lengthened measurement arm can be installed, after the lengthened measurement arm is connected with the expansion slot 32, the measurement range of the angle ruler can be significantly lengthened, meeting the needs of woodworkers when processing large wood or performing large area plane measurement, this design of adapting different expansion pieces through the expansion slot 32 enables the angle ruler to constantly adapt to various complex work scenes, further improving the functional diversity of the angle ruler, providing more comprehensive and powerful tool support for woodworkers, the working principle of the liquid bubble level 33 is based on the gravity characteristics of liquid and the movement law of bubbles in liquid, when the angle ruler is in a horizontal state, the bubble in the liquid bubble level 33 is located at the center position of the scale, in the process of using the angle ruler, the user only needs to observe the position of the bubble in the liquid bubble level 33 at any time, for example, when plane drawing is performed, in order to ensure that the drawn lines are horizontal, the user can place the angle ruler on the drawing plane, by observing whether the bubble is at the center position of the liquid bubble level 33, the user can judge whether the angle ruler is in a horizontal state, if the bubble deviates from the center position, the user can adjust the placement angle of the angle ruler to make the bubble return to the center position, thereby ensuring that the angle ruler remains in a horizontal position during use, in the process of woodworker machine adjustment, such as adjustment of the horizontal degree of the table surface of a woodworker saw bench, the liquid bubble level 33 of the angle ruler also plays a key role, by placing the angle ruler on the table surface of the saw bench, observing the position of the bubble and making corresponding adjustment, the table surface of the saw bench can be ensured to be in a horizontal state, thereby ensuring the accuracy of sawing work, this design of accurately measuring the horizontal state of the angle ruler through the liquid bubble level 33 provides an important horizontal reference for woodworker operation, effectively improving the accuracy of measurement and operation, avoiding measurement errors and work mistakes caused by the angle ruler not being horizontal.
[0036] The above has made a detailed description of the present application in general, but some modifications or improvements can be made on the basis of the present application, which is obvious to those skilled in the art. Therefore, without departing from the spirit and principles of the present application, the modifications or improvements are within the scope of protection of the present application.
