Description

Technical Field

[0001] The invention relates to the technical field of piano key cover fixing devices, and in particular to a piano key cover connector. Background Art

[0002] The piano (Italian: pianoforte) is a keyboard instrument in Western classical music and is known as the "king of musical instruments". The connection of the piano cover mainly relies on the damper connector hinge. During the installation process, a certain concentricity must be maintained. The product highlights the result of changing the connection between the connector and the piano cover. The traditional connector and cover connection structure is a side screw connection with low connection strength and easy cracking of the plate. At the same time, when connecting the damper and the hinge, the concentricity installation is extremely high, which makes the installation difficult. Summary of the invention

[0006] Furthermore, the slide seat pressing plate includes a through groove formed on the slide seat pressing plate, an ear formed on one side of the through groove, and a through hole formed on the ear.

[0007] By adopting the above technical solution, the sliding seat pressing plate can clamp the sliding seat inside the connector base without affecting its horizontal sliding.

[0008] Furthermore, the fixing screws are arranged between the slide seat pressure plate and the connector base.

[0009] By adopting the above technical solution, the fixing screw is used to fix the slide seat pressure plate.

[0010] Furthermore, the bottom slide groove is slidably connected to the convex key.

[0011] By adopting the above technical solution, the automatic adjustment of the horizontal position of the sliding seat can be achieved, reducing the processing difficulty of the connector.

[0012] Furthermore, the number of the cover plate fixing threaded holes is three.

[0013] By adopting the above technical solution, the cover fixing threaded hole is used to fix the connector base on the piano cover.

[0014] Furthermore, the diameter of the sliding seat hole is larger than the outer diameter of the sliding seat.

[0015] By adopting the above technical solution, it can be ensured that there is a certain sliding gap between the sliding seat and the sliding seat hole.

[0016] Furthermore, the slide seat pressure plate is connected to the connector base via the fixing screws.

[0017] Furthermore, the bottom slide groove and the top slide groove form a cross.

[0018] By adopting the above technical solution, the position adjustment of the sliding seat in two directions can be achieved, thereby ensuring that the sliding seat can move freely in the horizontal direction.

[0019] Furthermore, the connector base, the sliding seat, and the sliding seat pressure plate are all made of stainless steel.

[0020] By adopting the above technical solution, the strength and service life of the connector can be ensured.

[0021] Furthermore, the width of the through slot is smaller than the width of the top slide slot.

[0022] By adopting the above technical solution, effective avoidance and fixation of the hinge can be achieved.

[0023] The specific working principle is: when in use, the connector base on the connector is connected to the front of the piano cover through the cover fixing threaded hole, which can solve the problem that the traditional side connection structure is not firmly installed, resulting in a reduced service life of the connector. At the same time, the hinge is fixed inside the top slide groove, the slide seat pressure plate is covered, and the slide seat pressure plate is fixed to the connector base through the fixing screws to achieve the connection between the piano cover and the hinge. The sliding seat is formed with a cross-shaped bottom slide groove and the top slide groove to ensure that the sliding seat can slide freely inside the slide seat fixing groove and the hinge can slide freely on the top slide groove, which effectively reduces the difficulty of installing the cover.

[0024] The beneficial effects of the present invention are:

[0025] 1. The connector body of the present invention is connected to the front of the piano cover in a through-type manner, which can solve the problem of the traditional side connection structure being unstable and prolong the service life of the connector;

[0026] 2. The present invention provides a cross bottom slide groove and a top slide groove on the sliding seat, thereby ensuring that the sliding seat can slide freely inside the sliding seat fixing groove, and the hinge can slide freely on the top slide groove, thereby ensuring the coaxiality of the connection between the cover plate and the hinge, and effectively reducing the difficulty of installing the cover plate.
