Description

Technical Field

[0001] This utility model relates to the field of measuring tool technology, and in particular to a telescopic multi-parameter combination measuring gauge. Background Technology

[0002] In the production and processing stages of industries such as machining, woodworking, and construction, accurate measurement of parameters such as the angle, length, height, depth, parallelism, and perpendicularity of workpieces is a key step in ensuring product quality.

[0003] Currently, most of the tools on the market used for measuring these parameters are single-function measuring instruments. For example, angle rulers can only measure angles, straight rulers are only used for length measurement, depth rulers are specifically for depth detection, and parallelism and perpendicularity detection still require the use of professional testing instruments. Standard parts matching also relies on specific comparison tools.

[0004] Due to the fragmented functions of existing measuring tools, they are no longer able to meet the high-efficiency and precise measurement needs of modern industrial production. Developing a combined measuring gauge that integrates multiple parameter measurement functions has become an urgent need for the industry. Utility Model Content

[0005] To overcome the shortcomings of existing measuring tools with fragmented functions, this utility model provides a telescopic multi-parameter combination measuring gauge.

[0007] Furthermore, the main body is a trapezoidal plate-shaped frame structure made of aluminum alloy, with an anodized surface for corrosion protection.

[0008] Furthermore, it also includes a reference fitting edge. The edge of the main scale body is provided with a reference fitting edge, which is milled to ensure straightness and perpendicularity, serving as a measurement reference surface.

[0009] Furthermore, the angle adjustment mechanism includes an L-shaped component, a damping rotating shaft, and a locking knob. The L-shaped aluminum alloy component is movably connected to the main scale body through the damping rotating shaft, and an angle locking knob is installed on the L-shaped component near the elongated adjustment hole.

[0010] Furthermore, it also includes a polygonal adapter slot group. A polygonal adapter slot group is provided near the angle measurement area of ​​the main scale body, including standard polygonal contour slots such as hexagonal and octagonal.

[0011] Furthermore, it also includes magnets, with magnets embedded in the bottom of the main body. Beneficial effects

Detailed Implementation

[0019] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Example: A telescopic multi-parameter combination measurement gauge, such as Figure 1-4As shown, it includes a main scale body 1, a straight line measuring area 101, an angle measuring area 102, a long strip adjustment hole 104, metric graduations 105, imperial graduations 106, a measuring rod 2, a sliding positioning block 3, and an angle adjustment mechanism 4. The bottom of the main scale body 1 is provided with a straight line measuring area 101, which is machined with high-precision millimeter graduations. The right side of the main scale body 1 is provided with an angle measuring area 102, which is engraved with an angle graduation of 0-45°. The main scale body 1 has a long strip adjustment hole 104 near the angle measuring area 102, and the angle adjustment mechanism 4 is installed thereon. The left side of the main scale body 1 is slidably connected to the measuring rod 2 and the sliding positioning block 3. The main scale body 1 is provided with metric graduations 105 and imperial graduations 106 near the measuring rod 2 and the sliding positioning block 3.

[0021] The main scale body 1 adopts a trapezoidal plate frame structure and aluminum alloy material, and is anodized. On the one hand, the trapezoidal structure makes the overall stress more reasonable, which is convenient for hand operation and can be placed stably. The aluminum alloy material has both lightweight and high strength characteristics, reducing fatigue while ensuring structural rigidity. On the other hand, the anodizing treatment forms a dense oxide film on the surface, which effectively resists external corrosion, greatly extends the service life of the main scale body 1, and ensures long-term measurement accuracy.

[0022] The reference mating edge 107 of the main scale body 1 is milled to ensure precise and controllable straightness and perpendicularity. During measurement, it serves as a unified reference surface, allowing the measurement operations of components such as the measuring rod 2 and the sliding positioning block 3, as well as angle measurement, parallelism and perpendicularity detection, to be carried out based on a stable and accurate reference. This reduces measurement errors caused by reference deviations from the source and significantly improves the overall accuracy of multi-parameter measurements.

[0023] The L-shaped component 401 is movably connected to the main scale body 1 via a damping rotation shaft 402 and locked by an angle locking knob 6. The damping rotation shaft 402 allows the L-shaped component 401 to be suspended at any angle within the range of 0-270°, making it convenient to adapt to complex angle measurement scenarios. The angle locking knob 6 adopts a ratchet structure, and the angle deviation is extremely small after locking. In conjunction with the elongated adjustment hole 104, it can not only flexibly measure special angles, but also use the elongated adjustment hole 104 to insert tools for operations such as drawing lines, thus expanding the functions of angle measurement and auxiliary processing.

[0024] The polygonal adapter slot group 103 of the main scale body 1 is equipped with standard polygonal contour slots such as hexagons and octagons. During measurement operations, standard parts such as bolts and nuts can be quickly placed into the corresponding contour slots. By observing the degree of fit, the standard parts' angles and shapes can be intuitively judged to ensure compliance. There is no need to use additional complex measuring tools, which simplifies the standard parts' angle and shape inspection process and improves the efficiency of compatibility inspection.

[0025] The magnet 5 embedded at the bottom of the main scale body 1 can generate a stable adsorption force during measurement. When facing a metal workpiece, the main scale body 1 can be quickly and firmly adsorbed onto the surface of the workpiece without the need for additional clamping. Especially in measurement scenarios such as vertical and horizontal planes, it effectively enhances the fit stability between the main scale body 1 and the workpiece, making the measurement operation more convenient, while ensuring the stability of the measurement reference and helping to improve measurement accuracy.

[0026] Angle measurement (non-standard inclined plane): The reference fitting edge 107 of the main scale body 1 fits against the reference surface of the workpiece. The L-shaped component 401 of the angle adjustment mechanism 4 is rotated to adapt to the inclined plane. After the locking knob 6 is fixed, the angle value of the angle measurement area 102 of the main scale body 1 is read. The accuracy can reach within 0.5°. If it is necessary to draw a line mark, draw a line along the edge of the L-shaped component 401 with a drawing pen.

[0027] Verticality test (wooden board splicing): The reference edge 107 of the main ruler body 1 is attached to the reference surface of one side of the wooden board (the magnet 5 attracts the metal clamp to enhance stability; if the wooden board is non-metallic, it is directly attached). The sliding measuring rod 2 is attached to the side of the other wooden board, and the parallelism between the measuring rod 2 and the reference edge 107 is observed.

[0028] Depth measurement (mortise and tenon): The sliding measuring rod 2 is inserted into the bottom of the mortise and tenon, and the reference fitting edge 107 of the main ruler body 1 is fitted to the surface of the wooden board. The length value corresponding to the metric / imperial scale of the measuring rod 2 is read (the measuring range is adapted to the mortise and tenon depth requirements).

[0029] Standard part angle verification (hex bolt): Place the hex bolt into the hexagonal contour groove of the polygonal adapter groove group 103 of the main scale body 1, observe the fit between the bolt head and the groove body, and judge whether the angle is standard; if it is necessary to measure the bolt length, slide the positioning block 3 against the top of the bolt and read the scale value.

[0030] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the present invention.
