Description

Self-positioning black key of piano keyboard

Technical Field

The utility model relates to a piano technical field especially relates to a piano keyboard is from line location black key.

Background

The current vertical piano is sold in increasing quantities at home and abroad, the production of the piano is also changed from a family type working room to a running mass production mode, the production of black and white keys is separately carried out on a production line of a piano keyboard, and the black keys are single keys separated by white keys, so that the black keys are required to be processed one by one during production, particularly the process of bonding the black keys is required to be carried out. Because the black keys are lack of positioning, the positioning and bonding are observed by naked eyes, the efficiency is low, and the higher bonding quality can not be ensured (the two sides of the black keys need to be flat and can not be inclined with the two sides of the key plate).

Disclosure of Invention

The utility model aims to solve the technical problem that a piano keyboard is from line location black key is provided, the quick location problem of black key when having solved production is solved to the miniature locating pin of black key body and the locating hole lock of keypad, improves production efficiency.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a piano keyboard is from line location black key, includes black key body and keypad, the both sides of black key body bottom all be provided with at least one miniature locating pin, bond together through glue between this black key body and the keypad, the keypad on be provided with the locating hole that matches with miniature locating pin.

As a supplement to the technical scheme of the utility model, the black key body adopt ABS engineering plastics to make.

As a supplement to the technical scheme of the utility model, miniature locating pin's diameter be 1 mm.

As a supplement to the technical scheme of the utility model, the bottom of black key body arranged rectangular form inner groovy along length direction.

As right technical scheme a supplement, the bottom of black key body be located the equal symmetrical arrangement in both sides of every tip of rectangular form inner groovy has two miniature locating pins.

As a supplement to the technical scheme of the utility model, the one end of black key body flush with the keypad and upper portion is provided with the slope.

As right technical scheme a supplement, miniature locating pin and black key body integrated into one piece.

Has the advantages that: the utility model relates to a self-positioning black key of a piano keyboard, wherein a micro positioning pin of a black key body is buckled with a positioning hole of a key board, so that the problem of quick positioning of the black key during production is solved, the production efficiency is improved, and the black key body is not deviated due to the influence of external force during the incomplete curing period of glue after being glued with the key board; and after-sale maintenance personnel can conveniently maintain the damaged black key keys.

Drawings

Fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is a schematic structural view of the black key body according to the present invention;

fig. 3 is a schematic structural diagram of the key board of the present invention.

The figure is as follows: 1. the key comprises a black key body, 2, a key plate, 3, a slope, 4, a long-strip-shaped inner groove, 5, a miniature positioning pin, 6 and a positioning hole.

Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.

The utility model discloses an embodiment relates to a piano keyboard is from line location black key, as shown in fig. 1-3, including black key body 1 and keypad 2, the both sides of black key body 1 bottom all be provided with at least one miniature locating pin 5, bond together through glue between this black key body 1 and the keypad 2, keypad 2 on be provided with the locating hole 6 that matches with miniature locating pin 5.

The black key body 1 is made of ABS engineering plastics, the ABS engineering plastics replace traditional solid wood black keys, cost can be effectively reduced, and the ABS engineering plastics have good impact resistance.

The diameter of the micro positioning pin 5 is 1 mm.

Long strip-shaped inner grooves 4 are arranged at the bottom of the black key body 1 along the length direction, and the design of the long strip-shaped inner grooves 4 can reduce the use materials of the whole black key body 1 and reduce the material cost.

The bottom of the black key body 1 is positioned on two sides of each end part of the strip-shaped inner groove 4, and two miniature positioning pins 5 are symmetrically arranged on the two sides of each end part of the strip-shaped inner groove.

One end of the black key body 1 is flush with the key plate 2, and the upper part of the black key body is provided with a slope 3.

Miniature locating pin 5 and black key body 1 integrated into one piece, joint strength and stability between assurance miniature locating pin 5 and the black key body 1.

The micro positioning pin 5 of the black key body 1 is buckled with the positioning hole 6 of the key plate 2, so that the problem of quick positioning of the black key in production is solved, the production efficiency is improved, and the deviation cannot be influenced by external force during the period that glue is not completely cured after the black key body 1 is glued with the key plate 2; and after-sale maintenance personnel can conveniently maintain the damaged black key keys.

Four positioning block cavities are processed in a pulse mode on the basis of an original black key mold, the four positioning blocks are used for assisting the forming of the miniature positioning pin 5, the four positioning blocks can also be used as secondary runner glue openings to ensure that the material is full after being cooled and formed, the runners are convenient to arrange, and the processing production is convenient (products and waste materials can be separated only by cutting off a main runner after being cooled and formed);

when the key board 2 is processed, a plurality of positioning holes 6 are drilled at corresponding positions of the key board 2 by using numerical control;

the black key body 1 after molding is directly bonded on the key board 2 coated with glue, and the four miniature positioning pins 5 are directly positioned with the positioning holes 6, so that the black key is ensured to be straight and not to be inclined under the influence of external force.
