The beneficial effect of adjustable electric phonograph disclosed by the utility model is: disc record is rotatablely connected by shaft and pedestal, Tone arm one end is set on pedestal by rotating boss, and the tone arm other end is equipped with pickup, by rotating boss by tone arm when use It is moved to above disc record, makes pickup part and record contacts；When turning knob, bull stick rotates together while being turned with moving gear It is dynamic, so that the rack gear that shoe surface is set is moved up and down, the rotating boss one above sliding shoe is driven ibid to move, reaches to setting The tone arm set on rotation convex block carries out the purpose adjusted up and down, to meet the length of different stylus and the thickness pair of different discs The height of tone arm has the purpose of different demands, to improve the sound quality of phonograph.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model adjustable electric phonograph.

Fig. 2 is the schematic diagram of internal structure of the utility model adjustable electric phonograph.

Specific embodiment

The utility model is further elaborated and is illustrated with Figure of description combined with specific embodiments below:

Fig. 1 and Fig. 2, a kind of adjustable electric phonograph, including pedestal 10, tone arm 11 and disc record 12 are please referred to, disc record 12 is logical It crosses shaft 13 and pedestal 10 is rotatablely connected, shaft 13 is set to 12 center of disc record, and shaft 13 is set to base far from 12 one end of disc record In seat 10, shaft 13 is attached with pedestal 10 by first bearing 14, is guaranteed that shaft 13 is able to carry out stable rotation, is reduced Friction between shaft 13 and pedestal 10；11 one end of tone arm is set on pedestal 10 by rotating boss 18,11 other end of tone arm Equipped with pickup 15, tone arm 11 is equipped with clump weight 16 far from 15 one end of pickup, is applied on gravity and tone arm 11 by clump weight 16, is made The contact obtained between 15 part of pickup and disc is more stable, will not vibrate influence pickup caused by the rotation because of disc record 12 Contact between 15 and disc, to improve the musical qualities of phonograph.

12 bottom of disc record is additionally provided with balancing disk 17, and balancing disk 17 is fixedly connected with disc record 12, and shaft 13 passes through balancing disk 17 Center increases the gravity of disc record 12 using balancing disk 17, enables disc record 12 more stable in rotation, reduces disc and sing There is a situation where bouncing pilotages between first 15, play more smooth.

Regulating mechanism is equipped between rotating boss 18 and pedestal 10, regulating mechanism includes knob 20, bull stick 21, second bearing 27, gear 22 and sliding shoe 23, sliding shoe 23 are set to 18 lower section of rotating boss, and pedestal 10, which offers, accommodates sliding shoe 23 Placing groove 24,24 inner wall of placing groove offer sliding slot 25, and 23 surface of sliding shoe is equipped with convex block 26 compatible with sliding slot 25, sliding Block 23 is slidably connected by convex block 26 with sliding slot 25, and knob 20 is set to 10 side of pedestal, and 21 one end of bull stick and knob 20 are fixed Connection, 21 other end of bull stick are penetrated in placing groove 24 and are fixedly connected in gear 22, and bull stick 21 and pedestal 10 use second bearing 27 It is rotatablely connected, 23 surface of sliding shoe is equipped with rack gear 28 compatible with gear 22, and gear 22 is meshed with rack gear 28.

In use, people first by disc place with disc record 12 on, then by tone arm 11 place with disc on, pass through turning knob When 20, bull stick 21 is rotated together while being rotated with moving gear 22, so that the rack gear 28 that shoe surface is arranged in is moved up and down, band The rotating boss 18 1 of dynamic 23 top of sliding shoe ibid moves, and reaches and carries out up and down to the tone arm 11 being arranged on rotation convex block 26 The purpose of adjustment has the mesh of different demands to the height of tone arm 11 to meet length and the thickness of different discs of different stylus , to improve the sound quality of phonograph.

25 inner wall of sliding slot is equipped with the gasket 29 for increasing frictional force, increases the frictional force between convex block 26 and sliding slot 25, so that Convex block 26 acts more slowly in moving process, avoids the speed too tone arm 11 near station from directly transmitting contact with disc and causes to damage The bad while slower up and down adjustment that can also make people more accurately carry out tone arm 11 of regulating the speed.

In above scheme, it is equipped with damping device in 10 bottom of pedestal, damping device includes spring 30 and soft rubber cushion 31, spring 30 one end are fixedly connected with pedestal 10, and the other end and the soft rubber cushion 31 of spring 30 are fixedly connected, and spring 30 is respectively set In four corners of pedestal, play a supporting role to pedestal 10；It is considerably reduced when playing phonograph by damping device Vibration amplitude between dish phonograph entirety and part mitigates the vibration of disc record 12, reduces the probability of bouncing pilotage, makes to play and more flow Freely.

The utility model provides a kind of adjustable electric phonograph: disc record is rotatablely connected by shaft and pedestal, and tone arm one end is logical It crosses rotating boss to be set on pedestal, the tone arm other end is equipped with pickup, and tone arm is moved to disc record by rotating boss when use Top makes pickup part and record contacts；When turning knob, bull stick is rotated together while being rotated with moving gear, makes to be arranged It moves up and down in the rack gear of shoe surface, drives the rotating boss one above sliding shoe ibid to move, reach and setting is being rotated Tone arm on convex block carries out the purpose adjusted up and down, to meet the length of different stylus and the thickness of different discs to the height of tone arm Degree has the purpose of different demands, to improve the sound quality of phonograph.

Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general Lead to it will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this The spirit and scope of utility model technical solution.
