Problem, the prior art be mostly between piano vestibular and shelves of locking a door set adjusting screw come adjust lock a door between shelves and key away from
From avoiding key and the scraping collision of shelves of locking a door with this.But such a mode can not in the flexural deformation of shelves that fundamentally avoids locking a door,
And adjustment adjusting screw is relatively complicated every time.
Utility model content
The purpose of this utility model is to propose that a kind of piano is locked a door shelves, it is unlikely to deform, and can ensure it between key
Gap uniformity, avoiding a grade scraping collision key of locking a door causes key not rise, reduce later period maintenance cost.
The utility model another object is that propose a kind of piano, ensure piano service life, reduce piano frequency of maintenance
And cost.
In order to achieve the above object, the utility model uses following technical scheme：
A kind of piano is locked a door shelves, it is characterised in that it include locking a door grade body and be adapted with grade body of locking a door plus
Firmware, the reinforcing member are fitted in grade body of locking a door towards on one side surface of fingerboard and upper end face, the reinforcing member
Including horizontal part and the vertical portion of described horizontal part one end is fixed on, the horizontal part is mutually perpendicular to form with the vertical portion
Hold chamber, grade body of locking a door fit in it is described hold intracavitary, the reinforcing member is prepared by allumen section bar.
Preferably, the binding face of the reinforcing member and grade body of locking a door is equipped with boss, grade body of locking a door
Groove is equipped with the binding face of the reinforcing member, the groove is equipped with the boss.
Preferably, it is described lock a door shelves and the reinforcing member it is glued together.
Preferably, being provided with screw hole on the reinforcing member, the reinforcing member further includes wood screw, and the wood screw can
It is connected lock a door grade body and the reinforcing member through the screw hole, the screw hole includes upper end screw hole and lower end
Screw hole, the upper end screw hole and the lower end screw hole are equidistantly provided with multiple along reinforcing member length direction.
Preferably, the reinforcing member lower end is provided with lower end boss towards fingerboard side, the lower end boss with
Fingerboard is clamped.
Preferably, the reinforcing member top is provided with through hole, the setting of the through hole along the reinforcing member length direction
Be conducive to mitigation to lock a door a grade overall weight, reduce reinforcing member internal stress.
The utility model additionally provides a kind of piano, including above-mentioned piano is locked a door shelves.
The beneficial effects of the utility model：
The utility model compared with prior art, by it is wooden lock a door shelves towards a side surface of fingerboard and on
The mode of surface bonding allumen section bar improves the integral strength for shelves of locking a door, and fundamentally avoids shelves of locking a door because humiture becomes
Deformation, solves the problems, such as since piano key does not rise caused by the deformation of shelves of locking a door caused by changing.
