Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1-Fig. 3, the utility model provides a kind of upright piano, including, piano frame 11, the back of the body of the piano frame
Face is provided with the first threaded rod 13 being vertically arranged with reinforcement 12, the side at the back side of the piano frame, and opposite side is provided with
Second threaded rod 14, the screw thread 17 of the threaded rod of screw thread 16 and second of first threaded rod is reverse；First screw thread
Bar is connected with the second threaded rod by nut or riffled tube 15, and riffled tube described herein is referred to female
Pipe.In general, first threaded rod and the second threaded rod are non-full thread threaded rod.Can be specifically with nut or interior
Screwed pipe junction is threaded, and other parts are not provided with screw thread, and reinforcement is easily propagated through when so installing, of course for convenient
It is fixed, it can also be threaded in the first threaded rod and the second threaded rod both ends.As a preferred mode, first spiral shell
Rasp bar and the second threaded rod are connected through the reinforcement with nut or riffled tube, i.e., set hole on reinforcement, and first
Threaded rod and the second threaded rod are connected through hole with nut or riffled tube, and so, the first threaded rod and the second threaded rod are added
The limitation of strengthening tendons, is not easy sideslip when screwing.
Upright piano provided by the utility model, can be with rotating nuts or riffled tube when being loosened in longitudinally connected part
The first threaded rod and the second screwed pipe is set to pull piano frame both ends to close up to centre, so as to solve wooden piano frame over time
In the vertical dehydration crackle and the problem of influence piano tonequality.Can certainly solve the wooden piano frame time in the same way
Long in the horizontal dehydration crackle and the problem of influence piano tonequality, design duplicates, i.e. the upper end at the back side of piano frame
First threaded rod is installed, lower end is provided with the second threaded rod, the screw thread of first threaded rod and the screw thread of the second threaded rod
To be reverse；First threaded rod is connected with the second threaded rod by nut or riffled tube.Due to making piano,
And there is reinforcement limitation, wooden piano frame is usually dehydration cracks influence piano tonequality in the vertical, therefore, typically to be solved
Be in the vertical dehydration crackle and the problem of influence piano tonequality.
In the application, applicant has also done following design, referring to Fig. 4-Fig. 6, first threaded rod and the second threaded rod
Connected by riffled tube；Being provided at both ends with longitudinally through in the jack 18 in riffled tube for the riffled tube, it is described to insert
Barrier sheet 19 is inserted with hole, one end of the barrier sheet is matched somebody with somebody with the screw thread of first threaded rod or the screw thread of the second threaded rod
Close, the thickness of in general barrier sheet is less than the pitch of the screw thread of the first threaded rod and the screw thread of the second threaded rod, or barrier sheet
The thickness of one end of the screw thread of close first threaded rod or the screw thread of the second threaded rod is less than the screw thread and second of the first threaded rod
The pitch of the screw thread of threaded rod, or barrier sheet close to the first threaded rod screw thread or the second threaded rod screw thread one end set
Wedgewise, and be inserted between the screw thread of the first threaded rod or the adjacent tooth of screw thread of the second threaded rod, these can be by this
Art personnel selection designs, and the other end of barrier sheet is located at outside jack and is connected with spring 20；On the riffled tube also
Support bar 21 is provided with, chute is provided with the support bar, the chute could be arranged to dovetail groove, be installed on the chute
There is sliding block 22；One end of the spring is connected with the barrier sheet, and the other end is connected with the sliding block.In order to facilitate fixation, institute
State and tightening knob 23 is provided with support bar, the tightening knob coordinates with the sliding block, in general, and tightening knob is positioned at support
The bottom of bar, referring to Fig. 4 or Fig. 5.Specifically, the spring, in the state of the barrier sheet, the spring is in original
Beginning state；In the state of the spring favours the barrier sheet, the spring is in extended state.This structure, adjusting
After good riffled tube tenses piano frame, pull sliding block barrier sheet is glided along jack and be against the screw thread or the second spiral shell of the first threaded rod
In the screw thread of rasp bar, sliding block is pulled on, spring is produced a downward pulling force and leftward or rightward pulling force to barrier sheet,
Barrier sheet is vertically and horizontally being had pulling force, screw after tightening knob fixes sliding block, internal thread can be prevented
Managing vibrated loosening makes tension effect be deteriorated.Certainly, sliding block can also be fixed otherwise, for example fixed by pin and even led to
Rope bundled fixed is crossed, is not the key protection point of the application herein, here is omitted.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
