Description

TECHNICAL FIELD

[0001] The utility model relates to piano production equipment technical field, especially for the measurement and scribing link of piano key side wood, and specifically relates to a piano key side wood measurement and scribing gauge. BACKGROUND

[0002] In the current piano key side wood measurement work, the steel ruler is a commonly used tool. However, when using the steel ruler to measure, the staff not only needs to record the measurement size manually, but also still relies on the steel ruler to position during the key side wood scribing process. This series of operations not only easily introduces human error in the recording and positioning links, but also the whole process is relatively cumbersome and time-consuming, causing a great burden on the vision of the operator, resulting in low work efficiency. At the same time, this traditional measurement method requires high professional technical level of the technician, and the technician needs to have rich experience and high operation proficiency to ensure the accuracy of measurement and scribing. SUMMARY

[0003] The utility model aims at overcoming the drawbacks of the prior art, and carefully designs a piano key side wood measurement and scribing gauge which is ingenious in design, simple in structure, easy to operate and extremely high in measurement accuracy.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0005] A piano key side wood measurement and scribing gauge, comprising a flat strip and a right-angle strip; the right-angle strip has a horizontal edge and a vertical edge, and the horizontal edge of the right-angle strip is arranged towards the flat strip and connected with the flat strip through a connecting rod hinge assembly to form a movable telescopic structure, so that the distance between the two measurement edges (the flat strip and the right-angle strip) can be flexibly adjusted according to different measurement requirements, greatly improving the applicability of the tool. When measuring the distance between the piano side arm and the key, the flat strip is attached to the side of the piano side arm, the right-angle strip is moved to the outside of the vertical edge to attach to the side of the key, the movable telescopic structure is fully utilized, and the distance between the piano side arm and the key is quickly and accurately measured; when scribing, the position relationship between the flat strip and the right-angle strip during measurement is maintained, the inside of the vertical edge of the right-angle strip is tightly attached to the side surface of the key side wood, and the outside edge of the flat strip is scribed, so that the required size of the key side wood is scribed.

[0006] In the utility model, the flat strip is selected for one of the measurement edges, which provides a stable basis for measurement and scribing due to its good flatness and adhesion. The right-angle strip is selected for the other measurement edge, which relies on the outside of the right-angle strip during measurement and the inside of the right-angle strip during scribing.

[0007] Further, the thickness of the right-angle strip is 1mm. The 1mm thickness serves as the standard gap between the piano side arm and the key, providing a precise reference for the whole measurement and scribing process.

[0008] Further, the connecting rod hinge assembly includes two connecting rods, one end of the two connecting rods is hinged together, and the other end of the two connecting rods is respectively hinged with the flat strip and the horizontal side of the right angle strip.

[0009] Further, the flat strip and the right angle strip are both aluminum strips.

[0010] In order to realize the flexibility and adaptability of the measuring tool, the two measuring edges form a movable telescopic structure which can easily adjust the distance between the two measuring edges according to actual needs in different measuring scenes, greatly improving the practicability of the measuring and marking gauge. BRIEF DESCRIPTION OF DRAWINGS

[0011] The utility model will be further explained in detail in combination with the drawings and specific embodiments:

[0012] Fig. 1 The whole structure schematic diagram of the utility model is presented;

[0013] Fig. 2 The use state schematic diagram of the utility model in measurement is shown;

[0014] Fig. 3 The use state schematic diagram of the utility model in marking is shown. SPECIFIC EMBODIMENT

[0015] As Figs. 1-3 The utility model discloses a piano key side wood measuring and marking gauge, including flat strip 1 and right angle strip 2, wherein the flat strip 1 and the right angle strip 2 are all aluminum strips.The right angle strip 2 has horizontal side and vertical side, and the horizontal side of the right angle strip 2 is arranged towards the flat strip 1 and is connected with the flat strip 1 through connecting rod hinge assembly 3 to form a movable telescopic structure, so that the distance between the two measuring edges (flat strip 1 and right angle strip 2) can be flexibly adjusted according to different measuring needs, greatly improving the applicability of the tool.

[0016] Among them, the connecting rod hinge assembly 3 has two groups, the connecting rod hinge assembly 3 includes two connecting rods, one end of the two connecting rods is hinged together, and the other end of the two connecting rods is respectively hinged with the flat strip 1 and the horizontal side of the right angle strip 2.Each hinge part has certain damping, so that the whole tool has the function of shaping.

[0017] When measuring the distance between the piano side arm 5 and the key 4, the flat strip 1 is closely attached to the side of the piano side arm 5, and the right angle strip 2 is moved to be attached to the side of the key 4 outside the vertical edge, so that the distance between the piano side arm 5 and the key 4 can be quickly and accurately measured by the movable telescopic structure; when marking, the position relationship between the flat strip 1 and the right angle strip 2 in the above measurement is kept, the inner side of the vertical edge of the right angle strip 2 is closely attached to the side of the key side wood 6, and a line is drawn along the outer edge of the flat strip 1, so that the required size of the key side wood 6 is marked.

[0018] In the utility model, the flat strip 1 is selected as one of the measuring edges, and the flat strip 1 has good flatness and close attachment, thereby providing a stable basis for measurement and marking.

[0019] Further, the thickness of the right angle strip 2 is 1mm, and the thickness of 1mm is just the standard gap between the piano side arm 5 and the key 4, thereby providing a precise reference for the whole measurement and marking process.

[0020] In actual operation, the technician closely attaches the flat strip 1 of the piano key side wood measuring and marking gauge to the side of the piano side arm 5, and the vertical edge of the right angle strip 2 is attached to the side of the key 4 outside, and the accurate distance between the piano side arm 5 and the key 4 is quickly measured by the movable telescopic structure; then, the position relationship between the flat strip 1 and the right angle strip 2 in the above measurement is kept, and the inner side of the right angle strip 2 is closely attached to the side of the key side wood 6, and since the thickness of the right angle strip 2 is 1mm (which is just the standard gap between the key side wood 6 and the key 4), the technician can accurately mark the required size of the key side wood 6 along the edge of the outer side of the flat strip 1.

[0021] The specific embodiments of the utility model are described above, but those skilled in the art should understand that this is only an example, and those skilled in the art can make various changes or modifications to the embodiments without departing from the principles and essence of the utility model, and these changes and modifications all fall within the protection scope of the utility model.
