Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole embodiments.Based on the embodiment in the utility model, every other embodiment that those of ordinary skill in the art are obtained under the premise of not making creative work, broadly fall into the scope of the utility model protection.
Referring to Fig. 1-4, the utility model provides a kind of technical scheme: include connecting plate 1；Described connecting plate 1 has bolt hole a2 near the position at four angles；The middle position in described connecting plate 1 front is welded with two support plates 3；It is provided with space between two described support plates 3；The top of two described support plates 3 has hole a14；It is provided with telescopic piston 4 between two described support plates 3；The top of described telescopic piston 4 has hole b15；It is connected by bearing pin 5 between described telescopic piston 4 and chord seat board 3；The bottom of described telescopic piston 4 is connected with pneumatic cylinder 8；The bottom of described pneumatic cylinder is connected with installing plate 9；Described pneumatic cylinder 8 is connected with connecting tube 11 in the side near installing plate 9；Described connecting tube 11 and the junction of pneumatic cylinder 8 are provided with sealing ring a10；The other end of described connecting tube 11 is connected with high-voltage energy storage cylinder 13；The flanking central position of described high-voltage energy storage cylinder 13 is provided with sealing ring b12；Sealed by sealing ring b12 between described connecting tube 11 and high-voltage energy storage cylinder 13；Two described support plates 3 are just to installation；The material of two described support plates 3 is stainless steel；Described high-voltage energy storage cylinder 13 is equipped with high pressure nitrogen；Described bearing pin 5 passes through the hole a14 of the support plate 3 and hole b15 of telescopic piston 4；Described bearing pin 5 two ends are provided with locking cap 6；Described telescopic piston 4 is provided with sealing ring c16 with pneumatic cylinder 8 junction；Described sealing ring c16 is connected with pneumatic cylinder 8 end face middle position；Described pneumatic cylinder 8 end face periphery is provided with location-plate 7；The middle position of described location-plate 7 has positioning hole 17；Described pneumatic cylinder 8 passes through positioning hole 17.
Connecting plate 1 in the specific implementation, is connected by the utility model with fingerboard；It is fixed on installing plate 9 on piano；At location-plate 7 and fingerboard, plane is in same level position；When fingerboard declines, connecting plate 1 compresses also with decline, telescopic piston 4；Due to the effect of bearing pin 5, the level angle of connecting plate 1 constantly converts, and thus ensures the vertical change of telescopic piston 4, telescopic piston 4 is pressed into pneumatic cylinder 8, gas is compressed, and compressed gas enters high-voltage energy storage cylinder 13, thus achieves the slow fall motion of the fingerboard that gases at high pressure are buffering.
