Detailed Implementation

[0025] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0026] like Figures 1-4 As shown, this utility model provides a technical solution:

[0027] A universal turntable assembly for a vinyl record player includes:

[0028] A belt rotation groove is fitted at the center of the outer side wall of the base 1. A protective structure 3 is fitted at the center of the inner side wall of the base 1. The protective structure 3 includes a protective layer 301 fitted onto the inner side wall of the base 1. A wear-resistant pad 302 is provided at the center of the lower end face of the base 1. A wear-resistant layer 303 is provided at the center of the lower inner wall of the base 1. A counterweight 304 is fitted inside the base 1 on the inner side wall of the protective layer 301. A sealing plate 305 is provided at the center of the upper end face of the counterweight 304. Both the protective layer 301 and the wear-resistant pad 302 are made of rubber. The sealing plate 305... Made of carbon fiber, the protective structure 3 plays an important role in protecting and stabilizing the turntable assembly. The protective layer 301 is made of rubber, which can prevent dust and reduce the impact of external impacts on the internal structure. The wear-resistant pad 302 and the wear-resistant layer 303 are also made of rubber, which can reduce the friction between the base 1 and the placement surface, ensuring the smooth rotation of the turntable. The counterweight 304 can increase the weight and stability of the entire turntable assembly. The sealing plate 305 is made of carbon fiber, which has a certain sealing effect and also enhances the stability of the entire structure with the properties of carbon fiber.

[0029] A turntable structure 4 is fitted inside the sealing plate 305. The turntable structure 4 includes a first gear 401, which is located at the center of the upper surface of the wear-resistant layer 303. A second gear 402 is located on the upper surface of the wear-resistant layer 303 on one side of the first gear 401. The first gear 401 has four sliding tracks 403 arranged in a ring. A record placement tray 404 is located at the center of the upper surface of the first gear 401. A placement pad 405 is located at the center of the lower inner wall of the record placement tray 404. The placement pad 405 is made of polyvinyl chloride. One end of each of the four sliding tracks 403 passes through the upper surface of the record placement tray 404 and the placement pad 405. Each of the four sliding tracks 403 has an adjusting rod 406 at its center. The four adjusting rods 406 are slidably connected inside the four sliding tracks 403. Each of the four adjusting rods 406 has an adapter ring 407 at its center on its upper surface. The second gear 402 has a rotating rod 408 at its center on its upper surface. The first gear 401 and the second gear 402 mesh with each other. The inner wall of the first gear 401 is fitted with a rotating shaft 2.

[0030] When different records need to be placed, rotating the lever 408 directly drives the second gear 402 to rotate. Since the first gear 401 and the second gear 402 are meshed, according to the gear transmission principle, the rotation of the second gear 402 will drive the meshed first gear 401 to rotate in the opposite direction. Therefore, the rotation of the second gear 402 can drive the first gear 401 to start rotating. When the first gear 401 rotates, it will drive the adjusting rods 406 in the four sliding tracks 403 to move. The four adjusting rods 406 slide and connect respectively. The adjustment rod 406 is connected inside the sliding track 403, and each adjustment rod 406 has an adapter ring 407 at the center of its upper end face. After the record is placed on the placement pad 405, the position of the adjustment rod 406 in the sliding track 403 can be adjusted by rotation or according to actual usage needs, thereby changing the position of the adapter ring 407 and enabling the placement of records of different sizes. The base 1 is rotated by the rotating shaft 2, and the record placement tray 404 is rotated by the base 1. The adapter ring 407 is moved and extended by the rotating rod 408 sliding inside the sliding track 403 to accommodate different records.

[0031] The working principle of this utility model is as follows:

[0032] The rubber protective layer 301 effectively prevents dust and other impurities from entering the turntable assembly and affecting the normal operation of the components. It also reduces the impact of external shocks on the internal structure, acting as a buffer and protecting the internal precision components. Both the wear-resistant pad 302 and the wear-resistant layer 303 are made of rubber. Rubber is wear-resistant and reduces friction between the base 1 and the placement surface, ensuring the turntable rotates smoothly on the placement surface and preventing vibrations caused by friction from interfering with the normal rotation of the turntable. The counterweight 304 increases the weight and stability of the entire turntable assembly. The heavier and more stable structure allows the turntable to maintain better stability during rotation, reducing shaking and displacement, and ensuring stable playback. The sealing plate 305 is made of carbon fiber, which has a certain sealing effect on the internal structure, preventing dust and other impurities from entering. Furthermore, by utilizing the high strength and other properties of carbon fiber, it enhances the stability of the entire structure, protecting and reinforcing the structural support of other internal components.

[0033] The first gear 401 and the second gear 402 mesh with each other. When different records need to be placed, the rotating rod 408 is rotated by hand, which drives the second gear 402 to make a circular motion. Based on the principle of gear transmission, the second gear 402 meshes with the first gear 401. The rotation of the second gear 402 will drive the first gear 401 to rotate in the opposite direction, thereby driving the first gear 401 to move. The first gear 401 has four sliding tracks 403 arranged in a ring. When the first gear 401 rotates, it drives the adjusting rods 406 in the four sliding tracks 403 to move. The adjusting rods 406 are slidably connected in the sliding tracks 403 respectively. Each adjustment rod 406 has an adapter ring 407 at the center of its upper end. After the record is placed on the placement pad 405, the user can rotate the rotating rod 408 or adjust the position of the adjustment rod 406 in the sliding track 403 according to actual usage needs, thereby changing the position of the adapter ring 407 to accommodate records of different sizes. The rotating shaft 2 drives the base 1 to rotate, and the base 1 drives the record placement tray 404 to rotate, thereby realizing the record rotation playback function. The rotating rod 408 slides inside the sliding track 403, causing the adapter ring 407 to move and extend to adapt to the placement and playback needs of records of different sizes or types.

[0034] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
