Description
Technical field
This utility model is related to a kind of slow drop device for piano keyhoard cover, belongs to light industry machinery technology field.
Background technology
Piano is typically made up of solid wood as high-grade keyboard instrument, piano keyhoard cover, it appears high-grade air, but shortcoming is relatively
For thick and heavy, close or run into during external force falls, cover of keyboard, in the presence of self gravitation, can accelerate to fall, to keyboard
And cover of keyboard causes damage in itself, the finger of pianist can be worked the mischief simultaneously.For overcoming the problems referred to above, market goes out
Show some buffer for cover on piano keyboards, had spring, also have hydraulic pressure rod-type, but to send out existing in the application slow fall effect
Really unsatisfactory, some products are inadequate to the support force of cover of keyboard, initial fall speed, and some products are last to fall
Stage control is bad, excessive with keyboard face contact force, simultaneously because the defect in structure, such product is fragile, changes difficulty
Greatly.
Content of the invention
The purpose of this utility model is: overcomes the above-mentioned deficiency in the presence of prior art, and provides a kind of reasonable in design,
Descending lifeline is easy for installation, and piano lid delays the good buffer for cover on piano keyboard of fall whole-process control effect.
For realizing the purpose of this utility model, employ the following technical solutions and be achieved: a kind of piano keyhoard cover buffering dress
Put, be made up of base plate, gripper shoe, tailstock, connecting seat, connecting rod, antivibrator and sealing device, the front end of described connecting rod is inserted in
Antivibrator, the rear end of connecting rod is inserted in connecting seat and is fixed, and the rear end of damping cavity is inserted in tailstock and is fixed, one end of described base plate and tail
Seat is flexibly connected, and the middle part of described gripper shoe is flexibly connected with connecting seat；Described connecting rod be fixedly arranged at the front end with sliding plug, sliding plug with
Antivibrator inwall has gap；Filling magnet a in magnetomechanical damping mechanism, sliding plug is set in described antivibrator and sliding plug, with magnet a
The relative magnet b of homopolarity is fixed on antivibrator bottom.It is inoculated with liquid in antivibrator, when piano lid needs to close, piano cover plate
Press down gripper shoe, connecting rod advances into antivibrator, the liquid of squeezed air-damping device bottom passes through between sliding plug and antivibrator
Gap flow to antivibrator front end, forms hydraulic damping it is ensured that cover of keyboard falls to starting the stable landing with the intermediate range stage, in steel
The final stage that qin cover plate falls, hydraulic damping declines, magnet a and magnet b is close, ensures cover of keyboard using magnetomechanical damping
Stable closing.When piano lid needs to open, magnetomechanical damping provides repulsion suitably to offset the gravity of piano lid, helps strength relatively
Little women and child's smooth opening piano lid.
Compared with prior art, the beneficial effects of the utility model are, by arranging magnetomechanical damping machine in damping intracavity
Structure, in the case of hydraulic damping declines, magnetomechanical damping effect strengthens, and closes final stage in cover of keyboard and plays stably resistance
Buddhist nun's effect is so that this utility model has the advantages that to provide double insurance to ensure the whole stable closing of cover of keyboard.
Brief description
Fig. 1 is this utility model buffer for cover on piano keyboard structural representation.
Fig. 2 is the mplifying structure schematic diagram in a region in Fig. 1.
