Description

Technical Field

[0001] This utility model relates to the field of support rod technology, and more specifically, to a stepless indexing and adjusting linkage mechanism and a directional support. Background Technology

[0002] Currently, there is a wide variety of support rods on the market, which can meet the adjustable support needs of placement on beds, tables, and other locations to a certain extent. However, they still have significant limitations for different application scenarios, especially in terms of basic positioning and steering adjustment functions.

[0003] In existing technologies, support rods can typically only be adjusted and positioned in stages according to preset angles, and cannot be finely adjusted according to actual needs. This results in a limited adjustment range and low flexibility for the support rods, making it difficult to achieve directional positioning at special angles between preset levels, and the functionality is relatively limited. At the same time, the basic positioning part and the rod part of the current support rods are generally fixed together, making it difficult to adapt to the orientation requirements of the rods for basic positioning adjustments, resulting in poor overall adaptability and flexibility.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0054] The terms "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation of this utility model. Any changes or adjustments to their relative relationships, without substantially altering the technical content, shall also be considered within the scope of implementation of this utility model.

[0055] like Figures 1 to 10 As shown, this utility model embodiment provides a stepless indexing adjustment linkage mechanism and an adjustment bracket including the stepless indexing adjustment linkage mechanism. The stepless indexing adjustment linkage mechanism includes an indexing adjustment structure 3 and a damping rotating shaft structure 4. The adjustment bracket further includes a positioning clamping structure 1, an extension support structure 2, and an adjustment hanging rod structure 5. These components work together to effectively achieve stepless indexing adjustment, overcoming the limitation of traditional support rod frames that can only perform stepped adjustment positioning according to a preset angle. Furthermore, it can achieve stepless indexing adjustment at any angle within a 360-degree range according to actual positioning angle requirements, significantly improving the flexibility of functional adaptation for different scenarios. Simultaneously, the relative detachability and interchangeability of the positioning clamping structure 1, the extension support structure 2, and the adjustment hanging rod structure 5 further enhances the overall flexibility of functional adaptation for different scenarios, thereby meeting diverse usage needs. Specific settings are as follows:

[0056] Please refer to Figures 1 to 3 The positioning and clamping structure 1 includes a clamping body 11, a first side threaded hole 12, and a second side threaded hole 13. The clamping body 11 can be configured as, but is not limited to, a screw-pressing clamp, to serve as the clamping and positioning base for the overall structure. The first side threaded hole 12 and the second side threaded hole 13 are respectively opened at two ends of the clamping body 11, so that the clamping body 11 can flexibly clamp and position the substrate at different orientations, and form support docking positions corresponding to different ends through the first side threaded hole 12 and the second side threaded hole 13.

[0057] Please continue to refer to this. Figure 3The extension strut structure 2 includes an extension strut body 21 and first strut connecting bolts 22 and strut connecting threaded holes 23, which are respectively fixedly disposed at both ends of the extension strut body 21. The first strut connecting bolts 22 are detachably screwed together with the first side threaded hole 12 or the second side threaded hole 13 to enable the extension strut body 21 to flexibly extend and support different end orientations based on the clamping body 11.

[0058] Please refer to Figure 3 and Figure 4 The indexing and adjusting structure 3 includes a base 31, an indexing 32, and a base support rod body 33. Both the base 31 and the indexing 32 are cylindrical, and are coaxially aligned. One end of the base support rod body 33 along its extension direction is fixedly connected to the base 31, and the other end of the base support rod body 33 along its extension direction is fixedly provided with a second support rod connecting bolt 34. The second support rod connecting bolt 34 is detachably screwed into the support rod connecting threaded hole 23, thereby forming a detachable extended support rod frame based on the clamping body 11 by extending the support rod body 21 and cooperating with the base support rod body 33.

[0059] Both the base seat 31 and the indexing seat 32 have indexing shaft holes 35 on their opposing sides. The base seat 31 and the indexing seat 32 also have positioning pin holes 36 that are connected to the indexing shaft holes 35. The positioning pin holes 35 and the positioning pin holes 36 are used to effectively position and assemble the damping shaft structure 4, thereby enabling the indexing seat 32 to rotate and adjust based on the base seat 31.

[0060] For details, please continue to refer to Figure 4 The damping shaft structure 4 includes a positioning shaft portion 41 and a rotation shaft portion 42 that is adapted to one end of the positioning shaft portion 41. Both the positioning shaft portion 41 and the rotation shaft portion 42 have mounting holes fixedly connected to their opposite sides. The mounting hole of the positioning shaft portion 41 is internally disposed within the rotation shaft hole 35 of the base seat portion 31, and the mounting hole of the rotation shaft portion 42 is internally disposed within the rotation shaft hole 35 of the rotation seat portion 32. The positioning pin hole 36 of the base seat portion 31 is fixedly connected to the mounting hole of the positioning shaft portion 41 via an internal pin, and the positioning pin hole 36 of the rotation seat portion 32 is fixedly connected to the mounting hole of the rotation shaft portion 42 via an internal pin, thereby enabling the rotation seat portion 32 to effectively rotate and adjust its orientation based on the base seat portion 31 using the damping shaft structure 4.

[0061] More specifically, the damping value of the damping shaft structure 4 is not less than 3 N·m, so as to ensure the load-bearing positioning stability of the indexing seat 32 after rotation and orientation adjustment based on the base seat 31.

[0062] Please continue to refer to this. Figures 1 to 3 The steering rod structure 5 includes a steering rod body 51 and a rod connecting bolt 52 fixedly disposed at one end of the steering rod body 51. A rotation connecting threaded hole 37 is also provided on one side of the indexing seat 32. The steering rod body 51 is screwed into the rotation connecting threaded hole 37 by the rod connecting bolt 52, so that the steering rod body 51 can further rotate synchronously based on the indexing seat 32, thereby completing the steering support function.
