Description
Technical field
The utility model belongs to piano striking machine part exchanging technical field, in particular to a kind of Shen Dazhen more changing device.
Background technique
Shen Dazhen is the joint of the component activities such as clutch in piano striking machine, turning device, damper, is equivalent to mechanical fortune
Dynamic bearing；During using piano striking machine, it may be frequently encountered the case where Shen is damaged up to needle due to various reasons,
Traditional Shen needs following several tools up to needle replacement: the workbench (pedestal in such as figure) with circular hole, red needle is (by old Shen Dazhen
Eject used tool), Portable hammer；Workflow: the part of needed to change Shen Dazhen is placed on the table, by red needle pair
Quasi- old Shen Dazhen taps red needle tail portion with hammer and old Shen Dazhen is ejected, the Shen Dazhen then more renewed, this process
It is relatively complicated, and each part tool weight is all heavier, it is not readily portable.
There are many tool used in traditional Shen Dazhen replacing options, and step is many and diverse, and the working strength of temperament teacher is larger, existing
Have it is also less in the document of Shen Dazhen replacement this respect in technology, in the prior art also without preferably replacing Shen Dazhen
Technology and the more complex defect of traditional method, the utility model proposes a kind of Shen Dazhen more changing devices, can be relatively easily
Shen Dazhen is replaced, the working efficiency of temperament teacher is improved.
Utility model content
The main purpose of the utility model is to overcome the defect pointed out in background technique, provides the novel replacement Shen of one kind and reaches
The device of needle keeps replacement Shen Dazhen more convenient.
To realize the above-mentioned technical purpose, the technical solution that the utility model is taken are as follows: a kind of Shen Dazhen more changing device, including
Pedestal, described base top one end are hinged with motion bar, and motion bar front end is rotatably connected to dress syringe needle, fill one upward of syringe needle
End is equipped with Shen Dazhen mounting groove, and the other end is fixedly installed with thimble；The pedestal be equipped with the matched placing groove of motion bar, put
Set slot front end be equipped with channel, channel straight down, when motion bar is overlapped with placing groove, the position and channel of Shen Dazhen mounting groove
Position be overlapped.
Preferably, the pedestal end is equipped with pivot, and motion bar is pivotally connected with pedestal.
Preferably, the shape of the dress syringe needle is T-shaped, is divided into front-end and back-end, thimble and Shen Dazhen mounting groove are all provided with
It sets on front end.
Preferably, the dress syringe needle energy 360 degree rotation.
Preferably, the length of the thimble is 2-5mm.
Preferably, the channel is circular channel.
Preferably, pedestal is run through in the channel.
Preferably, the number of the Shen Dazhen mounting groove is 3-5.
Preferably, the pedestal is cuboid.
Preferably, the pedestal is metal material.
Use tool various the utility model has the beneficial effects that the utility model compensates for traditional Shen Dazhen replacing options,
The disadvantage of step complexity improves replacement speed and temperament's teacher working efficiency, is adapted to the replacement of the multiple Shen Dazhen of polytypic
It needs；The design in channel can be convenient for collection Shen Dazhen；The design of thimble is then more easier taking-up Shen Dazhen；The utility model letter
Work step is changed, and easy to carry, will not have been forgotten to carry because of a tool and lead to not replace Shen Dazhen.The utility model
Clear thinking, principle is understandable, practical, has a good application prospect.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
1, Shen Dazhen mounting groove；2, syringe needle is filled；3, motion bar；4, pedestal；5, thimble；6, placing groove；7, channel.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment 1
A kind of Shen Dazhen more changing device, including pedestal 4, described 4 top one end of pedestal are hinged with motion bar 3, specific hinged
Form are as follows: 4 end of pedestal is equipped with pivot, and motion bar 3 is pivotally connected with pedestal 4；3 front end of motion bar is rotatably connected to dress needle
First 2, one end upward of dress syringe needle 2 is equipped with Shen Dazhen mounting groove 1, and the other end is fixedly installed with thimble 5, fills the shape of syringe needle 2
Be it is T-shaped, be divided into front-end and back-end, thimble 5 and Shen Dazhen mounting groove 1 are arranged on front end, and the length of thimble 5 is 2-5mm,
Dress syringe needle 2 can be rotated by 360 ° around motion bar 3, and the number of Shen Dazhen mounting groove 1 is 3-5；The pedestal 4 is equipped with and work
The front end of the matched placing groove 6 of lever 3, placing groove 6 is equipped with channel 7, and straight down, motion bar 3 is overlapped with placing groove 6 in channel 7
When, the position of Shen Dazhen mounting groove 1 is overlapped with the position in channel 7, and the channel 7 is circular channel and runs through pedestal 4.Pedestal 4
