Description

Technical Field

[0001] The utility model relates to the technical field of record players, in particular to a stop device for a record player. Background Art

[0002] A record player (formerly called a phonograph) is a sound playing device that works by reproducing the pressure changes of sound waves as accurately as possible through the fluctuations on the plane of the turntable. The needle moves along the grooves on the record, and the tip of the needle vibrates slightly with the fluctuations of the grooves. This vibration is transmitted to a membrane through a mechanical device, which amplifies it and dissipates it into the air.

[0003] In the prior art, when a traditional record player needs to be shut down, it is often necessary to manually lift the tonearm and then put it back on the clamp, but this manual operation is rather cumbersome, which directly leads to the user only lifting the tonearm and forgetting to turn off the record's rotating motor when the record player needs to be shut down, thereby increasing costs. In the prior art, the shutdown device of some record players often lifts the tonearm after turning off the record's rotating motor, and because the rotating motor has a small amount of rotational inertia after being turned off, the record will continue to rotate for a distance after the record's rotating motor is turned off, which directly leads to the user not being able to hear a part of the record the next time and missing it. Utility Model Content

[0004] The utility model aims to provide a stop device for a record player, which can solve the problem that when a traditional record player needs to be stopped, the tonearm often needs to be manually lifted and then put back on the clamp, but this manual operation is relatively troublesome. It avoids the problem that when the user needs to stop the record player, he may only lift the tonearm and forget to turn off the rotating motor of the record, which leads to increased costs. It can solve the problem that the stop device of some record players often lifts the tonearm after turning off the rotating motor of the record, and the rotating motor still has a little rotational inertia after being turned off. It avoids the problem that the record will rotate a certain distance after the rotating motor of the record is turned off, which leads to the problem that the user may miss a part of the record when using it next time.

[0005] To achieve the above object, a record player stopping device is provided, comprising a base, a turntable is arranged above the base, a support column is arranged on the right side of the turntable, a first rotating motor is arranged on the side of the support column, and a first rotating rod is fixedly connected to the output end of the first rotating motor;

[0006] A cartridge is arranged on the side of the support column, a second rotary motor is arranged inside the base, a second rotary rod is arranged above the second rotary motor, and a clamping device is arranged on the left side of the turntable.

[0007] According to the record player stopping device, the output end of the second rotating motor is fixedly connected to the second rotating rod, and a turntable is arranged above the second rotating rod.

[0008] According to the record player stopping device, a clamping motor is arranged below the clamping device, a bidirectional threaded rod is fixedly connected to the output end of the clamping motor, and a nut is threadedly connected to the outer surface of the bidirectional threaded rod.

[0009] According to the record player stopping device, a second connecting rod is fixedly connected to the right side of the nut, and a clamping block is fixedly connected to the side of the second connecting rod away from the nut.

[0010] According to the record player stopping device, a second sliding groove is provided on the right side of the bidirectional threaded rod.

[0011] According to the record player stopping device, a first slide groove is provided on the upper surface of the base, a first connecting rod is fixedly connected to the side of the first rotating rod, and a cartridge is fixedly connected to the side of the first connecting rod away from the first rotating rod.

[0012] According to the record player stopping device, a button is provided on the side of the clamping device.

[0013] According to the record player stopping device, a sliding column is fixedly connected below the first connecting rod, a supporting column is arranged on the side of the sliding column, and a soft clamping block is included on the left side of the supporting column.

[0014] The utility model has the following beneficial effects:

[0015] 1. Compared with the prior art, the stop device of the record player realizes the clamping of the turntable by setting a clamping device and a clamping block, so that the turntable stops rotating under the action of friction, thereby solving the problem that the stop device of some record players often lifts the tone arm after turning off the rotating motor of the record, and the rotating motor still has a little rotational inertia after turning off, thereby avoiding the problem that the record will rotate for a distance after the rotating motor of the record is turned off, thereby causing the user to miss a part of the record when using it next time.

[0016] 2. Compared with the prior art, the record player shutdown device, by setting the first slide groove and the first rotating motor, realizes that when the record player needs to be shut down, the first connecting rod is rotated under the action of the first rotating motor, and under the limiting action of the first slide groove, the slide column can only drive the cartridge to slide within a fixed range, thereby achieving the goal of not requiring the user to manually lift the first connecting rod and then place it on the clamp, thereby greatly improving the user's experience comfort.

[0017] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
