Description
Technical field
The invention belongs to black glue phonograph technical field more particularly to a kind of tone arm ramp-down devices.
Background technology
Vinyl record almost occupies entire 20th century as a kind of sound and the carrier of music, until the birth of nineteen eighty-two CD
It is raw.China entered the CD epoch in 1992, and black glue production line is largely eliminated, and the price of vinyl record falls to 15 from 30 yuan or so
Member or so.But due to the hobby of collector, since 1994, the price of vinyl record was gradually gone up, just prominent by 1996
It is hundred yuan broken.Domestic the last item black glue production line is closed within 1998, and the vinyl record of domestic market is all to introduce abroad
Or it is second-hand.Generally the least expensive vinyl record wants six or seven ten yuans now, and that collects version can be thousands of.
Putting down pickup put the moment sung, pickup can fall onto disc, can be transmitted in loudspeaker " bang " a sound, this
Sample had both influenced audition impression, was also detracted from pickup, disc.
Invention content
In order to overcome the deficiencies in the prior art, the invention discloses a kind of tone arm ramp-down devices.
The present invention is achieved through the following technical solutions：
A kind of tone arm ramp-down device, including shell, which is characterized in that enclosure is equipped with guide post, between guide post and shell
Coated with damping oil reservoir；Tone arm supporting rod is equipped at the top of guide post, cover top portion is equipped with through-hole, and the top of tone arm supporting rod, which passes through, to be led to
Shell is stretched out in hole；Spring is equipped at the top of guide post between cover top portion；Guide post bottom is equipped with lug, and lug has been arranged right below
Horizontal axis is fallen, the side for the horizontal axis that rises and falls is equipped with groove corresponding with lug length；The horizontal axis that rises and falls is fixed on the shell, and rise and fall horizontal axis
Shell is stretched out in one end, and the part that the horizontal axis that rises and falls stretches out shell is equipped with the handle that rises and falls.
A kind of tone arm ramp-down device as described in claim 1, which is characterized in that the handle that rises and falls, is led at the horizontal axis that rises and falls
Column, shell, tone arm supporting rod and lug are aluminum.
Compared with prior art, the present invention has the following advantages：
The present invention ramp-down device pickup can be allowed slowly to drop on disc, to solve pickup fall to
On disc, noise problem can be transmitted in loudspeaker.
Description of the drawings
Fig. 1 is the sectional view of embodiment 1.
Specific implementation mode
Embodiment 1
A kind of tone arm ramp-down device as shown in Figure 1, including shell 4, shell 4 are internally provided with guide post 3, guide post 3 and shell 4
Between be coated with damping oil reservoir；3 top of guide post is equipped with tone arm supporting rod 6, and 4 top of shell is equipped with through-hole, the top of tone arm supporting rod 6
Portion passes through through-hole to stretch out shell；3 top of guide post and shell are equipped with spring between 4 top；3 bottom of guide post is equipped with lug 7, lug 7
Be arranged right below the horizontal axis 2 that rises and falls, the side of the horizontal axis 2 that rises and falls is equipped with groove corresponding with 7 length of lug；The horizontal axis 2 that rises and falls is fixed
On shell 4, shell 4 is stretched out in the one end for the horizontal axis 2 that rises and falls, and the part that the horizontal axis 2 that rises and falls stretches out shell is equipped with the handle 1 that rises and falls.
The handle 1 that rises and falls, the horizontal axis 2 that rises and falls, guide post 3, shell 4, tone arm supporting rod 6 and lug 7 are aluminum.
In use, the tone arm of phonograph to be placed on to the top of tone arm supporting rod 6, when needing to put down tone arm, risen and fallen by pushing
Handle 1 drives the rotation of horizontal axis 2 of rising and falling, after the handle 1 that rises and falls pushes in place, the groove face lug 7 risen and fallen on horizontal axis 2, and lug
7 due to not supporting, while under the pressure of spring 5, and tone arm supporting rod 6, guide post 3 and lug 7 will be sunk together, but in guide post
Damping oil is coated between 3 and shell 4, tone arm supporting rod 6 will be with guide post 3 and slowly sink under the action of damping oil, and
It is not to suddenly drop to bottom, such tone arm also slowly declines under the drive of tone arm supporting rod 6, finally slowly allows pickup to be pressed onto and sings
On piece, it is therefore prevented that the decline of pickup drop type multifunction.
Above example is merely to illustrate the present invention, but be not limited to the scope of the present invention, it is every according to the present invention
Technical spirit still falls within technical solution of the present invention to any simple modification, equivalent change and modification made by following instance
In range.
