Description

Technical Field

[0001] This utility model relates to the field of record player technology, and in particular to a record player mechanism. Background Technology

[0002] A record player, also known as a phonograph, is a sound reproduction device. Its sound is stored in arc-shaped grooves etched into the surface of a record using acoustic methods. The record is placed on a turntable and rotates under the stylus. Most current record player mechanisms use a large circular platter to support the record. Positioning posts are fixed on the platter to prevent the record from sliding during rotation. The platter is driven by a motor to rotate, causing the pickup arm to produce corresponding sounds by contacting different parts of the platter. However, while the existing positioning posts can prevent the record from sliding, they lack a limit on the record's movement. When using this device, the rotation of the tonearm can easily cause the platter to vibrate, resulting in the record shaking up and down during rotation.

[0003] Chinese utility model patent CN217982827U discloses a record player mechanism, including a base with a rotating device within it. A stabilizing device is positioned above the rotating device. A tonearm is rotatably connected to the upper side of the base, and a stylus is detachably connected to one end of the tonearm near the rotating device. The stabilizing device includes: a positioning post positioned on the upper side of the rotating device; a groove formed on the outer wall of the positioning post; and a limiting rod rotatably connected to the groove. This record player mechanism, through the use of the stabilizing device, can limit the record to the platter during operation, preventing platter vibration during tonearm rotation and avoiding record jitter, thus improving playback performance. Simultaneously, the use of ball bearings reduces friction between the platter and the limiting rod during rotation, extending the record's lifespan.

[0004] Regarding the aforementioned technology, the inventor believes it has the following drawbacks: The device uses ball bearings on limiting rods to secure the record. When a worker needs to remove the record, they must reset the limiting rods and move them into the groove, then use an insert rod to limit the two limiting rods. In actual use, the insert rod must be moved and stored every time a record is removed, resulting in a poor user experience. Utility Model Content

[0005] To solve the above problems, this utility model provides a record player mechanism.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a record player mechanism, including a base, a rotating device disposed on the base, a positioning post disposed on the upper surface of the rotating device, a tonearm disposed on the base, and a stylus disposed on the tonearm. Rotating grooves are provided on the two opposite side walls of the positioning post, and rotating holes are provided on the inner walls of the rotating grooves. A rotating rod is rotatably disposed in the rotating holes, and a rotating plate is disposed on the rotating rod. Ball bearings are disposed on the bottom surface of the rotating plate. A limiting component for limiting the rotation plate is provided on the positioning post.

[0007] By adopting the above technical solution, when a worker needs to use a record, they simply pass the record through the positioning post, which allows the record to press against the upper surface of the rotating device, thus initially stabilizing the record. At this point, the worker only needs to press the drive rod to separate the limiting component from the rotating plate, causing the rotating plate to fall automatically under gravity. This causes the ball bearings on both rotating plates to simultaneously press against the record, thus stabilizing it. Subsequently, when the worker needs to change to a different record, they simply need to rotate the two rotating plates upwards in sequence, allowing them to remain stable under the action of the limiting component, without the need for additional tools, thereby reducing the difficulty of operation for the worker.

[0008] Furthermore, limit rods are fixed on the inner walls of the two rotating slots that are close to each other, and limit slots are formed on the upper surfaces of the two rotating plates.

[0009] Furthermore, the upper surface of the limiting rod is provided with a sliding groove, and the inner wall of the limiting groove is provided with a sliding hole. The limiting component includes a sliding block slidably disposed in the sliding groove, a compression spring fixed at one end to the bottom surface of the sliding block, and a connecting rope fixed at one end to the bottom surface of the sliding block. The other end of the compression spring is fixed to the inner bottom wall of the sliding groove.

[0010] Furthermore, inclined surfaces are provided on the edges where the sidewalls of the two sliding blocks, which are far apart from each other, intersect with their upper surfaces.

[0011] By adopting the above technical solution, when staff need to change different records, they only need to rotate the two rotating plates upwards in sequence. This connects the rotating plates with the limiting rod, allowing the sliding block to move completely into the sliding groove under the combined action of the rotating plates and the inclined surface. Subsequently, when the limiting groove is fully moved into place, the sliding groove and the sliding hole are aligned. The sliding block connects with the sliding hole under the action of the compression spring, thus stabilizing the limiting rod and consequently the rotating plate. No additional tools are needed, reducing the difficulty of operation for staff.

[0012] Furthermore, a drive groove is provided on the upper surface of the positioning column, and a drive rod is slidably disposed in the drive groove. The ends of the two connecting ropes that are close to each other are fixed to the drive rod.

[0013] By adopting the above technical solution, when the staff places a new record on the rotating device, the staff only needs to press the drive rod to make the two connecting ropes move downwards simultaneously with the drive rod, thereby causing the two sliding blocks to move downwards simultaneously. This allows the two sliding blocks to separate from the two rotating plates in turn, and then the two rotating plates to automatically rotate downwards under the action of gravity, thus reducing the difficulty of operation for the staff.

[0014] Furthermore, a support spring is fixed on the inner bottom wall of the drive groove, and the other end of the support spring is fixed to the bottom surface of the drive rod.

[0015] By adopting the above technical solution, when the drive rod is not subjected to external force, the drive rod automatically remains stable under the action of the support spring, thereby reducing the probability of the connecting rope being pulled at this time, and thus improving the stability of the sliding block.

[0016] Furthermore, the upper end of the drive rod is provided with a rubber cap to reduce pain.

[0017] Furthermore, a torsion spring is fixed to the side wall of the rotating rod, and the other end of the torsion spring is fixed to the inner wall of the rotating hole.

[0018] By adopting the above technical solution, when the operator presses the drive rod, the rotating bar is continuously subjected to the force of the torsion spring, thereby increasing the probability that the rotating plate will rotate downward under the action of the torsion spring and gravity when the operator releases the rotating plate, thus improving the user experience of the device.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. In this application, when a worker needs to use a record, the worker must pass the record through the positioning post to press the record against the upper surface of the rotating device, thus initially stabilizing the record. At this time, the worker only needs to press the drive rod to separate the limiting component from the rotating plate, causing the rotating plate to fall automatically under the action of gravity, thereby causing the ball bearings on both rotating plates to press against the record simultaneously, thus stabilizing the record. Subsequently, when the worker needs to change to a different record, the worker only needs to rotate the two rotating plates upwards in sequence to keep the rotating plates stable under the action of the limiting component, without the need for additional tools, thus reducing the difficulty of operation for the worker;

[0021] 2. In this application, when the operator needs to change different records, the operator needs to rotate the two rotating plates upwards in sequence, which connects the rotating plates with the limiting rod, so that the sliding block moves completely into the sliding groove under the combined action of the rotating plates and the inclined surface. Subsequently, when the limiting groove is completely moved into the limiting groove, the sliding groove and the sliding hole are aligned, and the sliding block connects with the sliding hole under the action of the compression spring, so that the limiting rod remains stable under the action of the sliding block, thereby keeping the rotating plate stable, without the need for additional tools, thus reducing the difficulty of operation for the operator;

[0022] 3. In this application, when the staff places a new record on the rotating device, the staff only needs to press the drive rod to make the two connecting ropes move downwards simultaneously with the drive rod, thereby causing the two sliding blocks to move downwards simultaneously. This causes the two sliding blocks to separate from the two rotating plates in turn, and then the two rotating plates automatically rotate downwards under the action of gravity, thereby reducing the difficulty of operation for the staff.

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0031] like Figure 1-6 As shown in the illustration, this application discloses a record player mechanism, including a base 1, a rotating device 11, a positioning post 2, a tonearm 21, a stylus 3, a rotating rod 41, a rotating plate 5, ball bearings 51, a limiting assembly 6, a limiting rod 7, a drive rod 81, a support spring 82, a rubber cap 83, and a torsion spring 9. The rotating device 11 is mounted on the base 1. The positioning post 2 is a cylindrical rod structure and is located on the upper surface of the rotating device 11. The tonearm 21 is mounted on the base 1, and the stylus 3 is mounted on the tonearm 21. Rotating grooves 31 are formed on the two opposite side walls of the positioning post 2, and rotating holes 4 are formed on the inner walls of the rotating grooves 31. The rotating rod 41 is a cylindrical rod structure and is rotatably mounted within the rotating holes 4. The rotating plate 5 is a rectangular plate structure and is mounted on the rotating rod 41. The ball bearings 51 are spherical structures and are located on the bottom surface of the rotating plate 5.

[0032] The limiting rod 7 is a rectangular rod-shaped structure. There are two limiting rods 7, which are fixed in sequence on the inner walls of the two rotating slots 31 that are close to each other. The upper surfaces of the two rotating plates 5 are provided with limiting slots 71.

[0033] The upper surface of the limiting rod 7 has a sliding groove 52, and the inner wall of the limiting rod 7 has a sliding hole 53. The limiting component 6 is mounted on the positioning post 2 and is used to limit the rotation plate 5. The limiting component 6 includes a sliding block 61, a compression spring 62, and a connecting rope 63. The sliding block 61 is a rectangular block structure and is slidably mounted in the sliding groove 52. One end of the compression spring 62 is fixed to the bottom surface of the sliding block 61, and the other end of the compression spring 62 is fixed to the inner bottom wall of the sliding groove 52. One end of the connecting rope 63 is fixed to the bottom surface of the sliding block 61, and inclined surfaces are provided on the edges where the sidewalls of the two sliding blocks 61 intersect with their upper surfaces.

[0034] When staff need to change records, they rotate the two rotating plates 5 upwards in sequence. This connects the rotating plates 5 with the limiting rod 7, allowing the sliding block 61 to move completely into the sliding groove 52 under the combined action of the rotating plates 5 and the inclined surface. Subsequently, when the limiting groove 71 is fully moved into its position, the sliding groove 52 aligns with the sliding hole 53. The sliding block 61 connects with the sliding hole 53 under the action of the compression spring 62, thus stabilizing the limiting rod 7 and consequently the rotating plates 5. This eliminates the need for additional tools, reducing the difficulty of operation for staff.

[0035] The upper surface of the positioning post 2 is provided with a drive groove 8. The drive rod 81 is a round rod structure and is slidably disposed in the drive groove 8. The ends of the two connecting ropes 63 that are close to each other are fixed to the drive rod 81. When the operator places a new record on the rotating device 11, the operator only needs to press the drive rod 81 to make the two connecting ropes 63 move downwards simultaneously with the drive rod 81. This causes the two sliding blocks 61 to move downwards simultaneously, thereby causing the two sliding blocks 61 to separate from the two rotating plates 5 in turn. As a result, the two rotating plates 5 automatically rotate downwards under the action of gravity, thus reducing the difficulty of operation for the operator.

[0036] One end of the support spring 82 is fixed to the inner bottom wall of the drive groove 8, and the other end of the support spring 82 is fixed to the bottom surface of the drive rod 81. When the drive rod 81 is not subjected to external force, the drive rod 81 automatically remains stable under the action of the support spring 82, thereby reducing the probability that the connecting rope 63 is pulled at this time, and thus improving the stability of the sliding block 61.

[0037] To improve the user experience, a rubber cap 83 is provided at the upper end of the drive rod 81 to reduce pain. One end of the torsion spring 9 is fixed to the side wall of the rotating rod 41, and the other end of the torsion spring 9 is fixed to the inner wall of the rotating hole 4.

[0038] When the operator presses the drive rod 81, the rotating rod 41 is continuously subjected to the force of the torsion spring 9, which increases the probability that the rotating plate 5 will rotate downward under the action of the torsion spring 9 and gravity when the operator releases the rotating plate 5, thereby improving the user experience of the device.

[0039] The working principle of a record player mechanism in this embodiment is as follows: When the operator needs to use a record, they need to pass the record through the positioning post 2, which will cause the record to press against the upper surface of the rotating device 11, thus initially stabilizing the record. At this time, the operator only needs to press the drive rod 81 to separate the limiting component 6 from the rotating plate 5, so that the rotating plate 5 will automatically fall under the action of gravity, and then the ball bearings 51 on the two rotating plates 5 will press against the record simultaneously, thus stabilizing the record. Subsequently, when the operator needs to change to a different record, they only need to rotate the two rotating plates 5 upwards in sequence, so that the rotating plates 5 will remain stable under the action of the limiting component 6, without the need for additional tools, thus reducing the difficulty of operation for the operator.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
