Description

Technical Field

[0001] This utility model relates to the field of mechanical adjustment device technology, specifically a dual-mode adjustment structure. Background Technology

[0002] With the increasing demands for flexibility and functionality in adjustment structures from modern industrial equipment and consumer electronics, traditional single-rotation adjustment methods are no longer sufficient to meet the multi-mode operation requirements in complex application scenarios.

[0003] Existing adjustment structures are mostly fixed or single-degree-of-freedom rotational structures, which can only achieve overall linkage adjustment or single-angle positioning, lacking independent adjustment capabilities, resulting in inconvenience in adjustment during actual use.

[0004] Therefore, a dual-mode regulation structure is urgently needed to solve the above problems. Utility Model Content

[0005] Based on the above, the purpose of this utility model is to provide a dual-mode adjustment structure to solve the problem of how to adjust rotational flexibility.

[0008] Frame;

[0009] A rotating shaft is rotatably mounted on the top of the frame.

[0010] A hollow shaft is connected and can be rotatably fitted onto its outer circumference relative to the rotating shaft;

[0011] The hollow connecting shaft can rotate synchronously under the drive of the rotating shaft, or it can rotate independently relative to the rotating shaft.

[0012] As a preferred embodiment of a dual-mode adjustment structure, an elastic washer is fitted on the rotating shaft. The two ends of the elastic washer abut against one end of the rotating shaft and one end of the connecting hollow shaft, respectively. The elastic washer is used to provide elastic buffering force when the connecting hollow shaft rotates relative to the rotating shaft, preventing loosening caused by vibration or external force, while improving the operating feel and positioning accuracy.

[0013] As a preferred embodiment of the dual-mode adjustment structure, it further includes a limiting component disposed between the frame and the connecting hollow shaft. The limiting component is used to limit the rotation angle range of the connecting hollow shaft relative to the rotating axis, so as to realize the positioning control and over-position protection of the rotation adjustment.

[0014] As a preferred embodiment of a dual-mode adjustment structure, the limiting component includes connecting contact points, an elastic element, and a limiting protrusion. Several connecting contact points are provided and spaced apart circumferentially along the connecting hollow shaft. The limiting protrusion is movably disposed on the frame. The elastic element is sleeved on the outer periphery of the limiting protrusion, with one end abutting against the frame and the other end abutting against the connecting contact point to provide a reset elastic force. When the connecting hollow shaft is rotated, the elastic element causes the limiting protrusion to contact the corresponding connecting contact point.

[0015] As a preferred embodiment of the dual-mode adjustment structure, it also includes a transmission connection assembly for driving the rotating shaft to rotate.

[0016] As a preferred embodiment of a dual-mode adjustment structure, the transmission connection assembly includes a transmission shaft, gears, and a chain. The transmission shaft is rotatably mounted on the bottom of the frame, the gears are fixed to the rotating shaft and the transmission shaft, and the chain is sleeved between adjacent gears and meshes with the gears.

[0017] As a preferred embodiment of the dual-mode adjustment structure, it further includes a mating component disposed on the connecting hollow shaft, the mating component being used for assembling external equipment.

[0018] As a preferred embodiment of a dual-mode adjustment structure, the mating component includes a support plate, a mating hole, and a positioning post. The support plate is positioned on the connecting hollow shaft, the mating hole is disposed on the support plate, and the positioning post is installed on the connecting hollow shaft, with the positioning post mating with the mating hole.

[0019] As a preferred embodiment of a dual-mode adjustment structure, the frame is a hollow structure, and the hollow area of ​​the frame is provided with connecting ribs that extend along the ends of the frame.

[0020] As a preferred embodiment of the dual-mode adjustment structure, the side of the connecting hollow shaft is provided with a groove, which is used to reduce mass.

[0021] The beneficial effects of this invention are as follows: by setting a hollow connecting shaft and a rotating shaft that can rotate relative to each other, two adjustment modes can be freely switched. The hollow connecting shaft can rotate synchronously under the drive of the rotating shaft, or it can be adjusted at a local angle independently of the rotating shaft, meeting the flexible operation needs in different usage scenarios.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0037] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0038] In one embodiment of this utility model, such as Figure 1-5 As shown, a dual-mode adjustment structure is provided, including: a frame 1, a rotating shaft 2, and a connecting hollow shaft 3. The frame 1; the rotating shaft 2 is rotatably disposed on the top of the frame 1; the connecting hollow shaft 3 is rotatably sleeved on the outer periphery of the rotating shaft 2; wherein, the connecting hollow shaft 3 rotates synchronously under the drive of the rotating shaft 2, and can also rotate independently relative to the rotating shaft 2.

[0039] The dual-adjustment structure provided by this utility model achieves free switching between two adjustment modes by setting a connecting hollow shaft 3 and a rotating shaft 2 that can rotate relative to each other. The connecting hollow shaft 3 can rotate synchronously under the drive of the rotating shaft 2, or it can be adjusted locally independently of the rotating shaft 2, meeting the flexible operation needs in different usage scenarios.

[0040] Moreover, this utility model is easy to operate, which not only improves the flexibility of adjustment and positioning accuracy, but also enhances the user experience and stability. It is suitable for various devices that require multi-angle adjustment, such as lamps, cameras, and displays, and has good practicality and market application prospects.

[0041] Specifically, an elastic washer 4 (such as a spring washer) is fitted onto the rotating shaft 2, with its two ends abutting against one end of the rotating shaft 2 and the other end of the connecting hollow shaft 3. By providing the elastic washer 4 on the rotating shaft 2, with its two ends abutting against one end of the rotating shaft 2 and the other end of the connecting hollow shaft 3, stable elastic support is provided while achieving relative and synchronous rotation of the two. Moreover, the elastic washer 4 not only provides buffering and damping forces during the adjustment of the connecting hollow shaft 3, effectively preventing loosening caused by vibration or external forces, but also enhances the stability and positioning accuracy of the rotation operation.

[0042] In practice, shims can be added symmetrically to increase symmetrical damping force, thereby improving the stability of the connection between the rotating shaft 2 and the connecting hollow shaft 3.

[0043] In this utility model, the two ends of the drive shaft 601 are respectively provided with positioning flanges or limiting grooves. The spring washer is sleeved on the drive shaft 601 and is axially limited by the limiting grooves or flanges, thereby realizing the stable installation and elastic support function of the washer.

[0044] The dual-adjustment structure also includes a limiting component 5, which is set between the frame 1 and the connecting hollow shaft 3. The limiting component 5 is used to limit the rotation angle range of the connecting hollow shaft 3 relative to the rotating shaft 2, so as to realize the positioning control and over-position protection of the rotation adjustment.

[0045] Specifically, the limiting component 5 includes connecting contact points 501, elastic elements 502, and limiting protrusions 503 (such as screws, which are limited by nuts). Several connecting contact points 501 are provided and spaced apart circumferentially along the connecting hollow shaft 3. The limiting protrusions 503 are movably mounted on the frame 1. The elastic elements 502 are sleeved on the outer periphery of the limiting protrusions 503, with one end abutting against the frame 1 and the other end abutting against the connecting contact points 501, providing a restoring elastic force. When the connecting hollow shaft 3 is rotated, the elastic elements 502 cause the limiting protrusions 503 to contact the corresponding connecting contact points 501.

[0046] This invention, by setting a limiting component 5 consisting of connecting contact points 501, elastic elements 502, and limiting protrusions 503, enables precise positioning and gear adjustment of the rotation angle of the hollow shaft 3. Multiple connecting contact points 501 are distributed circumferentially at intervals. In conjunction with the movable limiting protrusions 503 and the elastic elements 502 providing reset force, the limiting protrusions 503 automatically contact their corresponding connecting contact points 501 during rotation, forming a stable limiting state. This structure not only effectively prevents over-rotation but also improves the operating feel and adjustment accuracy, enhancing the stability and controllability of the equipment. It is suitable for various application scenarios requiring high precision angle adjustment.

[0047] The dual-adjustment structure also includes a transmission connection assembly 6 for driving the rotating shaft 2 to rotate.

[0048] Specifically, the transmission connection assembly 6 includes a drive shaft 601, gears 602, and a chain belt 603. The drive shaft 601 is rotatably mounted on the bottom of the frame 1. All gears 602 are fixed to the rotating shaft 2 and the drive shaft 601. The chain belt 603 is sleeved between adjacent gears 602 and meshes with them. The meshing structure of the chain belt 603 and gears 602 provides reliable transmission and low noise, making it suitable for long-distance power transmission. It improves the smoothness and response speed of adjustment operations and enhances the overall structural coordination and functionality.

[0049] The dual-adjustment structure also includes a mating component 7, which is disposed on the connecting hollow shaft 3. The mating component 7 is used to assemble external equipment.

[0050] Specifically, the mating assembly 7 includes a support plate 701, a mating hole 702, and a positioning post 703. The support plate 701 is positioned on the connecting hollow shaft 3, the mating hole 702 is located on the support plate 701, and the positioning post 703 is installed on the connecting hollow shaft 3, engaging with the mating hole 702. By setting the mating assembly 7, composed of the support plate 701, the mating hole 702, and the positioning post 703, on the connecting hollow shaft 3, rapid installation and precise positioning of external equipment are achieved. The plug-in mating structure of the positioning post 703 and the mating hole 702 not only improves assembly efficiency but also enhances the stability and repeatability of the connection, improving the versatility and practicality of the adjustment structure.

[0051] In this embodiment, the support plate 701 can be used to mount a display screen or other devices that require angle adjustment.

[0052] Preferably, the frame 1 is a hollow structure, and the hollow area of ​​the frame 1 is provided with connecting ribs that extend along the ends of the frame 1. By setting connecting ribs in the hollow area of ​​the frame 1, not only is the strength and stability of the overall structure improved, but the deformation resistance of the frame 1 is also enhanced, while the overall weight is reduced, making it easier to install and maintain, and suitable for stable support requirements under various complex working conditions.

[0053] Preferably, the side of the connecting hollow shaft 3 is provided with a groove 8, which effectively reduces the weight and also reduces the material cost.

[0054] The adjustment process of the dual-rotation mode of this utility model is as follows:

[0055] Synchronous rotation mode. The transmission shaft 601 of the operation transmission connection assembly 6 drives the rotating shaft 2 to start rotating through the meshing transmission of gear 602 and chain belt 603 (via motor). When the rotating shaft 2 rotates, it can drive the connecting hollow shaft 3 to rotate synchronously.

[0056] Independent rotation mode enables relative rotation triggering. An independent external force (such as manual operation) is applied to the connecting hollow shaft 3 to overcome the resisting force of the elastic washer 4, causing the connecting hollow shaft 3 to start rotating relative to the rotating shaft 2.

[0057] The limiting process of this utility model is as follows: During the rotation, the limiting protrusion 503 (such as a screw) of the limiting component 5 is always in contact with the circumferential surface of the connecting hollow shaft 3 under the action of the elastic element 502 (such as a spring). When the connecting hollow shaft 3 rotates to the connecting contact point 501, the limiting protrusion 503 will contact the connecting contact point 501 to limit the rotation.

[0058] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
