Description

Technical Field

[0001] This utility model relates to the field of turntables, and in particular to a dual-positioning anti-deviation turntable. Background Technology

[0002] A turntable, as a mechanical device that enables an object to rotate around an axis, is essentially a precise fulcrum for controlling spatial orientation and motion trajectory. It is a comprehensive system integrating mechanical engineering, automatic control, and measurement technology. Through precise angle positioning and smooth motion control, it enables the loaded object to achieve directional or continuous rotation in a specific spatial dimension.

[0003] Patent CN222932695U discloses an assembly turntable. The set pads support the outer shell, and the upper clamping plate set on the rotating column ensures that the outer shell is stably positioned on the pads. The pads can also rotate in all directions and tilt, which facilitates the assembly of electronic display billboards. However, when using existing turntables, they usually use a single positioning structure to fix the position of the turntable, but they are still prone to slight displacement due to external forces, and the positioning effect is relatively poor. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a dual-positioning anti-deflection turntable. When existing turntables are used, they usually use a single positioning structure to fix the position of the turntable, but they are still prone to slight displacement due to external forces, and the positioning effect is relatively poor.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is a dual-positioning anti-deflection turntable, including a bearing top plate disposed on the upper side of a bearing base plate, and an active shaft rod penetrating one side of the bearing base plate. The end of the active shaft rod is fixedly connected to a main bevel gear. A support plate is fixedly connected to the upper surface of the bearing base plate. A driven shaft rod is disposed through the middle of the bearing top plate. A bearing platform is fixedly connected to the top of the driven shaft rod. A driven bevel gear is fixedly sleeved on the outer side of the driven shaft rod. A movable ring is fixedly connected to the bottom end of the driven shaft rod. A middle groove is opened in the middle of the bearing base plate.

[0006] A rotating shaft is provided through the bearing base plate. A connecting gear is fixedly connected to the bottom end of the rotating shaft. A serrated rod is provided on both sides of the connecting gear. A limit rod is fixedly connected to the serrated rod. A first connecting plate and a second connecting plate are fixedly connected to one end of the two sets of serrated rods, respectively. A fixing rod is fixedly connected to both the first connecting plate and the second connecting plate. A brake block is fixedly connected to the other end of the fixing rod. A limit groove is provided on the lower side of the bearing base plate.

[0007] As a further embodiment of this utility model: a drive motor is fixedly installed in the middle of one side of the supporting base plate, and the drive shaft is engaged with the output end of the drive motor, and the drive shaft is movably connected to the support plate.

[0008] As a further embodiment of this utility model: the driven bevel gear is located on the lower surface of the bearing top plate, and the main bevel gear meshes with the driven bevel gear; the movable ring is located inside the intermediate groove, and the brake block matches the movable ring.

[0009] As a further embodiment of this utility model: a positioning motor is fixedly installed on the upper side of the supporting base plate, and the rotating shaft is connected to the output end of the positioning motor, and the connecting gear is located inside the limiting groove.

[0010] As a further embodiment of this utility model: the two sets of sawtooth rods are symmetrically arranged about the center of the rotation axis, and both sets of sawtooth rods are meshed with the connecting gear. The first connecting plate and the second connecting plate are respectively located on both sides of the bearing base plate, and the fixed rod is movably connected to the bearing base plate.

[0011] As a further embodiment of this utility model: the supporting bottom plate is hinged to the supporting top plate via a connecting hinge, and a connecting groove is provided at one end of both the supporting top plate and the supporting bottom plate. A connecting rod is connected between the two sets of connecting grooves, and a rotating baffle is rotatably connected to both sides of the supporting bottom plate.

[0013] Compared with the prior art, the beneficial effects of this utility model include: when the turntable is stationary, by starting the positioning motor on the upper side of the bearing base plate, the rotating shaft and the connecting gear are driven to rotate together. Thus, the meshing connecting gear and the sawtooth rod, together with the limiting rod, drive the two sets of sawtooth rods to move relative to each other along the limiting groove. Then, the first connecting plate and the second connecting plate, together with the two sets of fixing rods, drive the two sets of brake blocks to move relative to each other until the two sets of brake blocks fix the moving ring. This replaces the single positioning structure of the existing turntable and realizes the dual positioning and anti-deviation function of the turntable, resulting in higher stability.

[0014] Compared with the prior art, the beneficial effects of this utility model include: first, rotating the two sets of rotating baffles away from the two ends of the connecting rod, then moving the connecting rod out from the inside of the two sets of connecting slots, and then rotating the bearing top plate relative to the bearing bottom plate through the connecting hinge until the bearing top plate is in a vertical state, thereby realizing the function of quick disassembly of the turntable, so as to carry out unobstructed inspection and maintenance of the drive structure and positioning structure.

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] Example 1, please refer to Figures 1-4A dual-positioning anti-deflection turntable includes a top support plate 2 mounted on the upper side of a base plate 1, and a drive shaft 4 penetrating one side of the base plate 1. A main bevel gear 5 is securely connected to the end of the drive shaft 4. A support plate 6 is fixedly attached to the upper surface of the base plate 1. A driven shaft 7 is penetrating through the middle of the top support plate 2. A support platform 8 is fixedly connected to the top of the driven shaft 7. A driven bevel gear 9 is securely sleeved on the outer side of the driven shaft 7. A movable ring 10 is securely connected to the bottom end of the driven shaft 7. A section is opened in the middle of the base plate 1. There is a middle groove 11, and a rotating shaft 13 is installed through the bearing base plate 1. The bottom end of the rotating shaft 13 is fixedly connected to a connecting gear 14. Both sides of the connecting gear 14 are provided with sawtooth rods 15. Limiting rods 16 are fixedly connected to the sawtooth rods 15. One end of the two sets of sawtooth rods 15 is fixedly connected to a first connecting plate 17 and a second connecting plate 18 respectively. Fixing rods 19 are fixedly connected to the first connecting plate 17 and the second connecting plate 18. The other end of the fixing rods 19 is fixedly connected to a brake block 20. A limiting groove 21 is opened on the lower side of the bearing base plate 1.

[0022] A drive motor 3 is fixedly installed in the middle of one side of the support base plate 1, and the drive shaft 4 is clamped to the output end of the drive motor 3. The drive shaft 4 is movably connected to the support plate 6. The driven bevel gear 9 is located on the lower surface of the support top plate 2, and the main bevel gear 5 meshes with the driven bevel gear 9. The movable ring 10 is located inside the middle groove 11, and the brake block 20 matches the movable ring 10.

[0023] In this embodiment, the meshing main bevel gear 5 and driven bevel gear 9 are used to rotate the driven shaft 7.

[0024] A positioning motor 12 is fixedly installed on the upper side of the bearing base plate 1, and the rotating shaft 13 is clamped to the output end of the positioning motor 12. The connecting gear 14 is located inside the limiting groove 21. Two sets of sawtooth rods 15 are symmetrically arranged about the center of the rotating shaft 13, and both sets of sawtooth rods 15 mesh with the connecting gear 14. The first connecting plate 17 and the second connecting plate 18 are located on both sides of the bearing base plate 1, and the fixing rod 19 is movably connected to the bearing base plate 1.

[0025] In this embodiment, the meshing connecting gear 14 and the sawtooth rod 15 cooperate with the limiting rod 16 and the limiting groove 21 to allow the two sets of sawtooth rods 15 to move relative to each other.

[0026] Specifically, by activating the drive motor 3 on one side of the support base plate 1, the drive shaft 4 and the main bevel gear 5 are rotated together. This, in turn, drives the driven shaft 7 to rotate through the meshing main bevel gear 5 and the driven bevel gear 9, which in turn drives the movable ring 10 and the support platform 8 to rotate together. When the turntable is stationary, by activating the positioning motor 12 on the upper side of the support base plate 1, the rotating shaft 13 and the connecting gear 14 are rotated together. This, in turn, drives the two sets of sawtooth rods 15 to move relative to each other along the limiting groove 21 through the meshing connecting gear 14 and the sawtooth rod 15 in conjunction with the limiting rod 16. This, in turn, drives the two sets of brake blocks 20 to move relative to each other through the first connecting plate 17 and the second connecting plate 18 in conjunction with the two sets of fixing rods 19, until the two sets of brake blocks 20 fix the movable ring 10. This replaces the single positioning structure of the existing turntable and realizes the dual positioning and anti-deviation function of the turntable, resulting in higher stability.

[0028] The top plate 2 has a rotation range of 0-90° via the connecting hinge 22. Both the top plate 2 and the bottom plate 1 have L-shaped cross-sections. The top plate 2 is connected to the bottom plate 1 via the cooperation of the connecting rod 24 and the connecting groove 23.

[0029] In this embodiment, the connecting rod 24 and the connecting groove 23 are used to connect the top plate 2 and the bottom plate 1.

[0030] Specifically, first, rotate the two sets of rotating baffles 25 away from the two ends of the connecting rod 24, then move the connecting rod 24 out from the inside of the two sets of connecting slots 23, and then rotate the bearing top plate 2 relative to the bearing bottom plate 1 through the connecting hinge 22 until the bearing top plate 2 is in a vertical state, thus realizing the function of quick disassembly of the turntable, so as to carry out unobstructed inspection and maintenance of the drive structure and positioning structure.
