Abstract
Description
Technical Field
[0001] The utility model belongs to the field of measuring tools, in particular to a multifunctional vernier caliper. Background Art
[0002] Vernier calipers, as a common measuring tool, play a key role in many measurement scenarios. They can accurately measure the length, inner and outer diameters, and depth of objects. They are mainly composed of two parts: a main scale and a vernier scale that can slide flexibly on the main scale. A set screw is specially installed at the top of the vernier scale to temporarily fix the vernier scale.
[0003] In one usage scenario, the user measures the length to be cut with a ruler and then marks the cutting position with a marker. This operation requires the user to coordinate both hands to perform the steps of gesturing and drawing lines. The existing technology lacks a measuring tool that can simultaneously measure and mark scales. Utility Model Content
[0004] The utility model aims to provide a multifunctional vernier caliper capable of both measuring and drawing.
[0005] To achieve the above-mentioned purpose, the utility model provides a multifunctional vernier caliper, comprising a main scale and a vernier scale, the vernier scale being slidable on the main scale, the vernier scale being provided with a set screw for temporarily fixing the position of the vernier scale, mounting seats being provided at the bottom of the main scale and the vernier scale, and paintbrushes being provided on both mounting seats, the two paintbrushes being symmetrically distributed left and right, the two paintbrushes serving as outer measuring claws, and when the vernier scale moves to the zero point, the end faces of the two mounting seats being in contact with each other, and the tips of the two paintbrushes being close to each other as the zero point.
[0006] As an improvement of the above solution, the vernier caliper further includes two clamps, which surround the paintbrush. A flat connecting plate is provided on the side of the clamp, and the connecting plate is penetrated by bolts to be fixed to the mounting seat.
[0007] As an improvement to the above solution, an elastic rubber pad is provided on the inner wall of the clamp. When the clamp embraces the paintbrush, the elastic rubber pad is deformed to increase friction.
[0008] As an improvement of the above solution, the upper and lower ends of the clamp are open, and the upper and lower ends of the paintbrush both protrude from the upper and lower ends of the clamp. When the clamp is not tightened, the paintbrush can move along its own axial direction.
[0009] As an improvement to the above solution, the inclination angle of the paintbrush is less than 30° based on the vertical direction.
[0010] As an improvement to the above solution, the main ruler and the corresponding mounting seat are an integrated structure, and both have the same thickness.
[0011] The present utility model has the following beneficial effects: the user can conveniently operate the vernier caliper with one hand. When faced with the need to draw lines, the vernier ruler can be flexibly manipulated with one hand, quickly moved to the position corresponding to the required measurement length, and then the main ruler can be gently tilted to ensure that only the tip of one brush accurately touches the workpiece to be cut, thereby providing accurate line drawing guidance for subsequent cutting work. When only the task of measuring length needs to be performed, the two brushes can be temporarily used as measuring claws, which can also meet basic measurement needs and obtain more accurate length data. The significant improvement of this solution is that both measurement operations and line drawing operations can be easily achieved with one hand, which greatly improves the convenience of operation and work efficiency, and brings a smoother and more efficient use experience to users.

The terms "first," "second," and "third" are used solely for descriptive purposes and to distinguish technical features. They are not to be construed as indicating or implying relative importance, or as implicitly specifying the number or order of the technical features indicated.
[0016] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," and "set" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium, or they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances. The following describes an embodiment of the present invention based on its overall structure.
[0017] Reference Figure 1 The utility model discloses a multifunctional vernier caliper, including a main scale 11 and a vernier scale 12. The vernier scale 12 can slide on the main scale 11. The vernier scale 12 is provided with a set screw for temporarily fixing the position of the vernier scale 12. The bottom of the main scale 11 and the vernier scale 12 is provided with a mounting seat 21. A paintbrush 30 is provided on each of the two mounting seats 21. The two paintbrushes 30 are symmetrically distributed on the left and right. The two paintbrushes 30 serve as external measuring claws. When the vernier scale 12 moves to the zero point, the end faces of the two mounting seats 21 fit together, and the tips of the two paintbrushes 30 approach each other as the zero point.
[0018] As an improvement of the above solution, the vernier caliper further includes two clamps 22 , which surround the paintbrush 30 . A flat connecting plate is provided on the side of the clamp 22 , and the connecting plate is penetrated by bolts to be fixed to the mounting seat 21 .
[0019] As an improvement to the above solution, an elastic rubber pad is provided on the inner wall of the clamp 22 . When the clamp 22 embraces the paintbrush 30 , the elastic rubber pad deforms to increase friction, thereby preventing the paintbrush 30 from falling off.
[0020] As an improvement to the above solution, the upper and lower ends of the clamp 22 are open, and the upper and lower ends of the paintbrush 30 protrude from the upper and lower ends of the clamp 22. When the clamp 22 is not tightened, the paintbrush 30 can move along its own axis. This solution facilitates manual adjustment of the extension and retraction distance of the paintbrush 30 and facilitates alignment.
[0021] like Figure 1 As shown, the paintbrush 30 is a body of revolution with a conical bottom. As an improvement to the above scheme, the paintbrush 30 has an inclination angle of less than 30° based on the vertical direction. The smaller inclination angle of the paintbrush 30 is helpful for drawing lines.
[0022] As an improvement to the above solution, the main ruler 11 and the corresponding mounting base 21 are an integrated structure, and both have the same thickness. In this solution, the main ruler 11 and the mounting base 21 can be processed from a long strip of plate, which has high processing efficiency.
[0023] The user can conveniently operate the vernier caliper with one hand. When faced with the need to draw lines, the vernier ruler 12 can be flexibly manipulated with one hand, quickly moved to the position corresponding to the required measurement length, and then the main ruler 11 can be gently tilted to ensure that only the tip of one brush 30 accurately touches the workpiece to be cut, thereby providing accurate line drawing guidance for subsequent cutting work. When only the task of measuring length needs to be performed, the two brushes 30 can be temporarily used as measuring claws, which can also meet basic measurement needs and obtain more accurate length data. The significant improvement of this solution is that both measurement operations and line drawing operations can be easily achieved with one hand, which greatly improves the convenience of operation and work efficiency, and brings a smoother and more efficient user experience to users.
