Description

Technical Field

[0001] This utility model relates to the technical field of fixing devices for dynamic capture equipment, and in particular to a fixing device for dynamic capture equipment. Background Technology

[0002] Motion capture equipment, such as motion capture cameras;

[0003] In some cases, we mount motion capture equipment on height-adjustable masts to capture motion at different heights. Traditional telescopic adjustable masts, such as... Figure 7 A hand-tightened screw or bolt is installed on the threaded connection of the outer rod. The inner rod is locked by the lateral compression of the bolt. This is not only unsightly, but also causes the outer side to bulge. Furthermore, the concentrated compression force at one point will cause the surface of the inner rod to deform, affecting the smoothness of the extension and retraction.

[0004] Specifically, in this case, the technical problem we need to solve is to provide a telescopic and height-adjustable rod device for fixing motion capture equipment (motion capture camera), especially improving the convenience of telescopic locking, as well as the external aesthetics, and reducing deformation caused by locking compression. Utility Model Content

[0005] A fixing device for a dynamic capture device includes an outer tube and an inner tube, wherein the inner tube is inserted into the outer tube and can move up and down;

[0006] The upper end of the inner tube is fitted with a mounting base, and the dynamic capture camera is fixed to the mounting base by bolts.

[0007] It also includes an adjusting lock, which runs vertically through the inner wall of the outer tube. The inner wall of the upper port of the outer tube is provided with threads. The adjusting lock is threadedly connected to the upper port of the outer tube. An inner ring is also welded and fixed inside the upper port of the outer tube. The inner ring is provided with an upwardly flared conical slope. The lower end of the adjusting lock is provided with elastic metal pieces at intervals in an annular shape. When the adjusting lock is tightened relative to the outer tube, the elastic metal pieces are further inserted into the gap between the inner ring and the inner tube and are squeezed and filled, thereby completing the compression locking of the inner tube.

[0008] Preferably, the adjusting lock includes a hand-tightening section, a threaded section, and an elastic metal sheet from top to bottom, wherein the elastic metal sheet is arranged in annular intervals at the lower end of the threaded section, and the threaded section is threadedly connected to the upper port of the outer tube.

[0009] Preferably, the outer wall of the elastic metal sheet is fixedly provided with a wedge-shaped protrusion, which cooperates with the inner ring. When the adjusting lock is loosened, the elastic metal sheet does not undergo elastic deformation because the inner ring does not press on it. At this time, the inner tube can extend and retract relative to the adjusting lock and the outer tube. When the adjusting lock is tightened, the elastic metal sheet and the inner ring press against each other, causing the end of the elastic metal sheet to bend elastically and clamp and squeeze the outer wall of the inner tube to complete the fixation.

[0010] Preferably, a rubber pressure block is also fixedly provided on the inner wall of the elastic metal sheet, and the rubber pressure block is positioned at a corresponding height to the wedge-shaped protrusion. In this way, when the wedge-shaped protrusion is pressed, the force is applied precisely to the rubber pressure block, thereby increasing the clamping friction through the rubber pressure block.

[0011] Preferably, the outer annular spacer of the hand-twisting section is fixedly provided with anti-slip flange strips to facilitate rotation and prevent slippage.

[0012] The advantages and positive effects of this utility model are:

[0013] Compared with existing technologies, this device is more aesthetically pleasing and compact, and easier to use and adjust. By rotating the adjusting lock, multiple rubber blocks simultaneously form multiple compression points on the outside of the inner tube. The force is dispersed through the annular interval. Compared with existing technologies, this device is more scientific and reasonable. Utilizing the material characteristics of the rubber blocks, it not only does not cause deformation of the inner tube surface but also increases friction, greatly improving the stability of the inner tube.

Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance. The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0024] like Figure 1-6 As shown, the fixing device of the dynamic capture device of this utility model includes an outer tube 10 and an inner tube 11, wherein the inner tube 11 is inserted into the outer tube 10 and moves up and down.

[0025] The upper end of the inner tube 11 is fitted with a mounting base 15, and the dynamic capture camera 14 is fixed on the mounting base 15 by bolts.

[0026] It also includes an adjusting lock 13, which runs vertically through the outer tube 10. The inner wall of the upper port of the outer tube 10 is provided with threads. The adjusting lock 13 and the upper port of the outer tube 10 are threadedly connected. An inner ring 22 is also welded and fixed inside the upper port of the outer tube 10. The inner ring 22 is provided with an upwardly flared conical inclined surface. The lower end of the adjusting lock 13 is provided with elastic metal pieces at intervals. When the adjusting lock 13 is tightened relative to the outer tube 10, the elastic metal pieces are further inserted into the gap between the inner ring 22 and the inner tube 11 and are squeezed and filled, thereby completing the compression locking of the inner tube 11.

[0027] Preferably, the adjusting lock 13 includes a hand-tightening section 18, a threaded section 17, and an elastic metal sheet 19 from top to bottom. The elastic metal sheet 19 is arranged in annular intervals at the lower end of the threaded section 17, and the threaded section 17 is threadedly connected to the upper port of the outer tube 10.

[0028] Preferably, the outer wall of the elastic metal sheet 19 is fixedly provided with a wedge-shaped protrusion 20, which then cooperates with the inner ring 22, such as... Figure 5 , 6 When the adjusting lock 13 is released, the inner ring 22 does not press on the elastic metal sheet 19, and the elastic metal sheet 19 does not undergo elastic deformation. At this time, the inner tube 11 can extend and retract relative to the adjusting lock 13 and the outer tube 10. When the adjusting lock 13 is tightened, the elastic metal sheet 19 and the inner ring 22 press against each other, causing the end of the elastic metal sheet 19 to bend elastically and clamp and squeeze the outer wall of the inner tube 11 to complete the fixation.

[0029] Preferably, a rubber pressure block 21 is also fixedly provided on the inner wall of the elastic metal sheet 19, and the setting position of the rubber pressure block 21 is at a corresponding height position to the setting position of the wedge-shaped protrusion 20. In this way, when the wedge-shaped protrusion 20 is pressed, the force is applied to the rubber pressure block 21, and the clamping friction is increased by the rubber pressure block 21.

[0030] Preferably, the outer annular spacer of the hand-twisting section 18 is fixedly provided with anti-slip flange strips 16 to facilitate rotation and prevent slippage.

[0031] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
