Technical Field

[0001] This utility model relates to the field of musical instrument auxiliary equipment technology, and in particular to a cello stand. Background Technology

[0002] Music stand is a key auxiliary device that supports musical instruments such as pianos, keyboards, and violins. It is mainly made of high-strength alloy or solid wood.

[0003] A search of Chinese patent publication number "CN207558395U" reveals "a kind of instrument stand". The instrument stand can adjust the angle and position of the pillow seat according to the shape and specifications of different instruments by circumferentially moving the pillow seat around the connecting shaft, so that the instrument stand can hold instruments of different specifications and types; and the position of the pillow seat is locked by a first adjustment mechanism to improve the stability of the instrument stand.

[0004] Based on the above search and existing technology findings, the above patent has certain defects: although the angle of the pillow can be adjusted by the circumferential movement of the pillow around the connecting shaft to adapt to different sizes of instruments, it is difficult to meet the needs of orderly placement of multiple instruments and cannot achieve centralized storage and management of multiple instruments. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a cello stand that solves the technical problem of inconvenience in using existing cello stands.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A cello stand includes a base, the inner side of which has a circular groove, and a first bearing is provided inside the circular groove. The outer ring of the first bearing is fixedly installed to the inner wall of the circular groove. The inner ring of the first bearing is fixedly mounted with a suspension structure; The suspension structure includes a rotating column, which is rotatably mounted to a circular groove. A turntable is fixedly mounted on the upper end of the rotating column, and multiple brackets are fixedly mounted on the upper end of the turntable. A U-shaped rotating shaft seat is fixedly mounted on the upper end of each bracket, and a rotating plate is rotatably mounted on the inner side of the U-shaped rotating shaft seat. A hook is fixedly mounted on the side wall of the rotating plate.

[0007] Preferably, a hexagonal column is fixedly installed on the inner side of the turntable, and multiple side rods are fixedly installed on the side wall of the hexagonal column. The hexagonal column is located at the center of the turntable, the side rods are located above the bracket, the lower end of the side rod is provided with a spotlight, and the upper end of the side rod is fixedly installed with a handle.

[0008] Preferably, the base has an annular groove on its inner side, and a second bearing is provided inside the annular groove. The outer ring of the second bearing is fixedly installed with the inner wall of the annular groove, and a sealing ring is fixedly installed with the inner ring of the second bearing. The sealing ring is rotatably installed with the annular groove and fixedly installed with the turntable.

[0009] Preferably, a rotating block is rotatably mounted on the side wall of the U-shaped rotating shaft seat away from the sealing ring, a tension spring is fixedly installed between the bracket and the rotating plate, connecting rods are symmetrically rotatably mounted on the outer side of the rotating block, a locking pin is rotatably mounted on the inner side of each set of connecting rods, a locking groove group is opened inside the base, the locking pin passes through the turntable and is adapted to the locking groove group, and the locking pin is slidably mounted with the turntable.

[0010] The beneficial effects of this utility model are: Firstly, by setting up a suspension structure, staff can place cellos on the hooks on the bracket. Once all the hooks are in place, staff can rotate the handle to drive the turntable to rotate, thus achieving stable suspension and convenient rotation for display and retrieval of the cellos, meeting the needs for orderly placement and flexible operation of multiple cellos.

[0011] Secondly: When the staff places the cello's headstock on the hook, the cello's weight exerts downward pressure on the hook, causing the rotating plate to rotate towards the hook side around the U-shaped pivot. At this time, the side of the rotating plate away from the hook, i.e., the side connected to the rotating block, will lift upwards, thus causing the rotating block in contact with it to rise synchronously. As the rotating block rises, it pulls the locking pins through the connecting rods at both ends, causing the locking pins to move upwards along the sliding channel of the turntable. Finally, the end of the locking pin disengages from the locking slot assembly of the base, completing the unlocking of the base from the turntable. After unlocking, the turntable can rotate freely. When removing a cello from a single hook, the hook... When the hook loses its own weight, the tension spring between the bracket and the rotating plate releases its elastic restoring force, pulling the rotating plate to rotate in the opposite direction to reset it. That is, the hook side rises and the rotating block side falls. After the rotating block falls, the tension of the connecting rod on the locking pin disappears. The locking pin slides downward under its own weight and the indirect force of the tension spring, and re-locks into the locking groove of the base, thus locking the base and the turntable. This process ensures that the turntable will not rotate or wobble accidentally when the cello is picked up, avoiding collisions between the cello being operated and other cellos placed on the bracket, thereby significantly improving the overall structural stability and safety of use.

Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: This application provides a cello stand that effectively solves the technical problem of inconvenience in using existing cello stands. By incorporating a suspension structure, staff can place cellos on the hooks of the stand. Once all hooks are occupied, staff can rotate a handle to drive a turntable, achieving stable hanging and convenient rotation for display and retrieval of the cellos. This meets the needs for orderly placement and flexible operation of multiple cellos. Furthermore, when the cello's headstock is placed on a hook, the cello's weight exerts downward pressure on the hook, causing the rotating plate to rotate towards the hook side around a U-shaped pivot. At this time, the side of the rotating plate away from the hook, i.e., the side connected to the rotating block, will lift upwards, causing the rotating block in contact with it to rise synchronously. As the rotating block rises, it pulls the locking pins via connecting rods at both ends. The locking pin moves upward along the sliding channel of the turntable, eventually disengaging its end from the base's locking slot assembly, thus unlocking the base from the turntable. After unlocking, the turntable can rotate freely. When a cello is removed from a single hook, the hook loses its own weight, and the tension spring between the bracket and the rotating plate releases its elastic restoring force, pulling the rotating plate to rotate in the opposite direction to reset it—that is, the hook side rises and the rotating block side falls. After the rotating block falls, the tension of the connecting rod on the locking pin disappears, and the locking pin slides downward under its own weight and the indirect force of the tension spring, re-locking into the base's locking slot assembly, thus locking the base from the turntable. This process ensures that the turntable will not rotate or wobble accidentally when a cello is removed, preventing the currently operated cello from colliding with cellos placed on other brackets, thereby significantly improving the overall structural stability and safety of the cello stand.

[0014] Example like Figures 1-5 As shown, the technical solution in this application embodiment effectively solves the technical problem of inconvenience in using existing piano stands. The overall idea is as follows: To address the problems existing in the prior art, this utility model provides a cello stand, including a base 11, a circular groove 12 is provided on the inner side of the base 11, a first bearing 13 is provided inside the circular groove 12, and the outer ring of the first bearing 13 is fixedly installed with the inner wall of the circular groove 12. The inner ring of the first bearing 13 is fixedly installed with a suspension structure; The suspension structure includes a rotating column 14, which is rotatably mounted to a circular groove 12. A turntable 15 is fixedly mounted on the upper end of the rotating column 14. Multiple brackets 16 are fixedly mounted on the upper end of the turntable 15. A U-shaped rotating shaft seat 17 is fixedly mounted on the upper end of the bracket 16. A rotating plate 18 is rotatably mounted on the inner side of the U-shaped rotating shaft seat 17. A hook 31 is fixedly mounted on the side wall of the rotating plate 18. By setting up a suspension structure, staff can place cellos on the hooks 31 on the bracket 16. Once all the hooks 31 are filled with cellos, staff can rotate the handle 23 to drive the turntable 15 to rotate, thereby achieving stable suspension and convenient rotation for display and retrieval of cellos, meeting the needs for orderly placement and flexible operation of multiple cellos.

[0015] A hexagonal column 19 is fixedly installed on the inner side of the turntable 15. Multiple side rods 21 are fixedly installed on the side wall of the hexagonal column 19. The hexagonal column 19 is located at the center of the turntable 15. The side rods 21 are located above the bracket 16. A spotlight 22 is provided at the lower end of the side rod 21. A handle 23 is fixedly installed at the upper end of the side rod 21. A hexagonal column 19 is fixed inside the turntable 15, and a spotlight 22 is provided at the lower end of the side rod 21 and a handle 23 is fixed at the upper end. The staff can drive the turntable 15 to rotate by rotating the handle 23. After the spotlight 22 is turned on, the light can illuminate the cello at the hook 31 on the bracket 16 from top to bottom, which makes it easier to display or pick up the cello on a certain hook 31 from a fixed perspective, effectively improving the convenience of display and picking up.

[0016] An annular groove 24 is provided on the inner side of the base 11. A second bearing 25 is provided inside the annular groove 24. The outer ring of the second bearing 25 is fixedly installed with the inner wall of the annular groove 24. A sealing ring 26 is fixedly installed with the inner ring of the second bearing 25. The sealing ring 26 is rotatably installed with the annular groove 24 and is fixedly installed with the turntable 15. When the turntable 15 rotates, it synchronously drives the sealing ring 26 to rotate in the ring groove 24. With the help of the rotation of the second bearing 25, the rotation of the turntable 15 can be made smooth. At the same time, the sealing ring 26 can seal the connection between the base 11 and the turntable 15 to prevent external impurities from entering the interior and affecting the operation of the components.

[0017] A rotating block 27 is rotatably mounted on the side wall of the U-shaped rotating shaft seat 17 away from the sealing ring 26. A tension spring 33 is fixedly installed between the bracket 16 and the rotating plate 18. A connecting rod 28 is symmetrically rotatably mounted on the outside of the rotating block 27. A locking post 29 is rotatably mounted on the inner side of each set of connecting rods 28. A locking groove group 32 is opened inside the base 11. The locking post 29 passes through the turntable 15 and is adapted to the locking groove group 32. The locking post 29 and the turntable 15 are slidably mounted. A rotating block 27 is rotatably mounted on the side wall of the U-shaped rotating shaft seat 17 away from the sealing ring 26. A tension spring 33 is fixedly installed between the bracket 16 and the rotating plate 18. The tension spring 33 is initially in a naturally stretched state and exerts a reverse tension force on the rotating plate 18. A connecting rod 28 is symmetrically rotatably mounted on the outer side of the rotating block 27. The two ends of the connecting rod 28 are movably connected to the rotating block 27 and the locking pin 29, respectively, and can transmit angle changes. A locking pin 29 is rotatably mounted on the inner side of each set of connecting rods 28. A set of locking grooves 32 matching the locking pins 29 are opened inside the base 11. The end of the locking pin 29 When the end is inserted into the slot assembly 32, it can restrict the relative rotation between the base 11 and the turntable 15. The locking post 29 passes through the turntable 15 and maintains a sliding fit with the turntable 15. The turntable 15 is provided with a channel for the locking post 29 to move to limit its vertical movement trajectory. When the operator places the cello head on the hook 31, the weight of the cello will exert downward pressure on the hook 31, causing the rotating plate 18 to rotate towards the hook 31 with the U-shaped pivot seat 17 as the fulcrum. At this time, the side of the rotating plate 18 away from the hook 31, that is, the side connected to the rotating block 27, will lift upward, thereby driving the rotation of the cello head. The rotating block 27 in contact with it rises synchronously; when the rotating block 27 rises, it pulls the locking pin 29 through the connecting rods 28 at both ends, causing the locking pin 29 to move upward along the sliding channel of the turntable 15, and finally allowing the end of the locking pin 29 to disengage from the locking slot group 32 of the base 11, completing the unlocking of the base 11 and the turntable 15. After unlocking, the turntable 15 can rotate freely; when the cello is taken off a single hook 31, the hook 31 loses its own weight pressure, and the tension spring 33 between the bracket 16 and the rotating plate 18 will release the elastic restoring force, pulling the rotating plate 18 to rotate in the opposite direction to reset, thus hooking. As the hook 31 rises and the rotating block 27 descends, the pulling force of the connecting rod 28 on the locking post 29 disappears. The locking post 29 slides downward under its own weight and the indirect force of the tension spring 33, and re-locks into the locking groove group 32 of the base 11, thus locking the base 11 and the turntable 15. This process ensures that the turntable 15 will not rotate or shake accidentally when the cello is taken out, and avoids the cello being operated from colliding with the cellos placed on other supports 16, thereby significantly improving the structural stability and safety of the overall cello stand.

[0018] Working principle: In use, the operator places the cello headstock on hook 31. Due to the cello's weight, the rotating plate 18 rotates towards hook 31 with the U-shaped pivot 17 as the fulcrum. During this process, the tension spring 33 stretches synchronously. As the rotating plate 18 rotates, the hook 31 side descends and the rotating block 27 side rises. Since the connecting rod 28 connects the rotating block 27 and the locking pin 29, the rising of the rotating block 27 synchronously drives the rotating block 27, connecting rod 28, and locking pin 29 upwards. With the help of the sliding limit effect of the turntable 15 on the locking pin 29, the locking pin 29 can achieve vertical lifting and lowering, ultimately disengaging the end of the locking pin 29 from the locking slot group 32, completing the unlocking operation. After all hooks 31 are filled with the cello, the operator can unlock the cello by rotating the handle... Hand 23 drives turntable 15 to rotate, so as to display or pick up cellos on hook 31 from a fixed perspective; when picking up a cello on a single hook 31, tension spring 33 will automatically reset, driving the locking post 29 to reset and re-lock into the locking slot group 32, thereby locking the base 11 and turntable 15, thus preventing the turntable 15 from rotating or shaking during the picking process, preventing collisions with cellos on other supports 16, and improving overall stability. In addition, when the spotlight 22 is turned on, the light can illuminate the cellos from top to bottom, further optimizing the display effect; when the turntable 15 rotates, it will simultaneously drive the rotating column 14 and sealing ring 26 to rotate in the circular groove 12 and the annular groove 24 respectively, ensuring the smoothness of the rotation process.
