Description

Technical Field

[0001] This utility model relates to the field of camera rig technology, specifically a multi-degree-of-freedom transformable fall-proof camera rig. Background Technology

[0002] In many filming processes, a camera stand is essential, with tripods being the most common. Tripods provide sturdy support for the camera, reducing camera shake during filming and improving image sharpness.

[0003] Currently, cameras are typically fixed to tripods using clips or screws. When using clips or screws to secure the camera, alignment is required, which is cumbersome and time-consuming, thus affecting shooting efficiency. Furthermore, when adjusting the camera angle, gravity causes it to tend to slide to one side. This process can loosen screws or clips, reducing the camera's stability and causing camera shake during angle adjustments. Utility Model Content

[0004] The purpose of this invention is to provide a multi-degree-of-freedom transformable anti-fall camera rig to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A multi-degree-of-freedom transformation fall-proof camera rig, comprising:

[0007] A fixed base is fixedly mounted on a tripod. A rotating base is rotatably mounted on the fixed base. A rotating block is rotatably mounted on the rotating base. A mounting base for placing a camera and an adjustment handle for adjusting the angle are fixedly mounted on the rotating block.

[0008] The mounting base is provided with a fixing component, which includes a lateral clamping structure and a longitudinal clamping structure. The lateral clamping structure and the longitudinal clamping structure cooperate to fix the camera on the mounting base.

[0009] The rotating base is also provided with an adjustment component, which is connected to the longitudinal clamping structure. When the adjustment handle is driven to adjust the pitch angle of the camera, the adjustment component can adjust the clamping force of the longitudinal clamping structure.

[0010] As described above, the multi-degree-of-freedom transformation fall-proof camera rig includes a first clamping plate. Two sets of the first clamping plates are symmetrically arranged along the length of the mounting base. The two sets of first clamping plates are symmetrically slidably arranged in two sets of first cavities opened on the mounting base. A first spring is provided in the first cavity. One end of the first spring abuts against the inner wall of the first cavity, and the other end abuts against the first clamping plate.

[0011] As described above, the multi-degree-of-freedom transformation fall-proof camera rig includes a second clamping plate. Two sets of the second clamping plates are symmetrically arranged along the width direction of the mounting base. The two sets of second clamping plates are symmetrically slidably arranged in two sets of second cavities opened on the mounting base. Each set of second clamping plates is fixedly provided with a telescopic rod. The telescopic rod is slidably connected to a plug-in cylinder fixedly arranged on the mounting base. A second spring is provided in the plug-in cylinder. One end of the second spring abuts against the telescopic rod, and the other end abuts against the adjustment component.

[0012] As described above, the multi-degree-of-freedom transformation fall-proof camera rig has two sets of adjustment components symmetrically arranged along the circumferential direction of the rotating seat mounting axis. Each set of adjustment components includes a drive structure and a moving structure. The moving structure includes a threaded sleeve that is slidably disposed in the plug-in cylinder. The threaded sleeve is threadedly connected to a lead screw that is rotatably installed in the plug-in cylinder.

[0013] As described above, the multi-degree-of-freedom transformation fall-proof camera rig includes a drive structure that is rotatably mounted on the plug-in cylinder. The drive gear engages with an arc-shaped toothed plate fixed on the mounting shaft and is connected to the lead screw via a bevel gear set.

[0014] As described above, the multi-degree-of-freedom transformation fall-proof camera rig has positioning blocks fixedly installed on both the first and second clamping plates. The positioning blocks are provided with guide ramps, which enable rapid positioning of the camera under the guidance of the guide ramps.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By utilizing the rotating connection between the rotating base and the fixed base, and between the rotating block and the rotating base, and in conjunction with the rotation of the adjustment handle, the camera can be freely adjusted to multiple angles, providing great flexibility and convenience for photography work.

[0017] By setting up a first clamping structure and a second clamping structure, during the installation of the camera, pressing down on the camera allows it to quickly align with the center of the mounting base under the guidance of the positioning blocks on the first and second clamping structures. After releasing the camera, the first and second clamping structures work together to stably fix the camera on the mounting base, thus achieving rapid installation and fixation of the camera.

[0018] Meanwhile, by setting up an adjustment component, when the camera tends to slide to one side due to gravity during tilt angle adjustment, the adjustment component can tighten the second spring on the tilt side to increase the clamping force on that side, thereby overcoming the sliding effect caused by gravity, improving the quality of the shot, and reducing the risk of the camera slipping off the mounting base during angle adjustment, thus improving safety and reliability during use.

[0028] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0029] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0030] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0031] Please see Figures 1-8 In this embodiment of the invention, a multi-degree-of-freedom transformation fall-proof camera rig includes:

[0032] A fixed base 2 is fixedly mounted on a tripod 1. A rotating base 3 is rotatably mounted on the fixed base 2. A rotating block 9 is rotatably mounted on the rotating base 3. A mounting base 5 for placing a camera and an adjustment handle 4 for adjusting the angle are fixedly mounted on the rotating block 9.

[0033] Specifically, a damping sleeve is provided between the rotating seat 3 and the fixed seat 2, and a damping sleeve is also provided between the rotating block 9 and the rotating seat 3. Under the action of the damping sleeve, the rotating seat 3 will not easily rotate relative to the fixed seat 2, and the rotating block 9 will not easily rotate relative to the rotating seat 3.

[0034] Specifically, when it is necessary to adjust the camera angle, rotating the hand adjustment handle 4 in the horizontal plane can drive the rotating base 3 to rotate the rotating block 9 relative to the fixed base 2, thereby adjusting the angle of the camera on the mounting base 5 in the horizontal plane; rotating the hand adjustment handle 4 in the vertical plane can drive the rotating block 9 to rotate relative to the rotating base 3, thereby adjusting the pitch angle of the camera; thus, multi-angle adjustment of the camera angle can be realized, providing convenience for the cameraman's filming work.

[0035] Further, please refer to Figures 1-8 The mounting base 5 is provided with a fixing component, which includes a horizontal clamping structure and a vertical clamping structure. The horizontal clamping structure and the vertical clamping structure cooperate to fix the camera on the mounting base 5.

[0036] The transverse clamping structure includes a first clamping plate 6. Two sets of the first clamping plates 6 are symmetrically arranged along the length of the mounting base 5. The two sets of the first clamping plates 6 are symmetrically slidably arranged in two sets of first chambers 501 opened on the mounting base 5. A first spring 12 is provided in the first chamber 501. One end of the first spring 12 abuts against the inner wall of the first chamber 501, and the other end abuts against the first clamping plate 6.

[0037] In particular, please see Figure 5 The first spring 12 is always in a stretched state, forcing the two sets of first clamping plates 6 to move closer to each other, thus providing a basis for subsequent clamping work.

[0038] The longitudinal clamping structure includes a second clamping plate 7. Two sets of the second clamping plates 7 are symmetrically arranged along the width direction of the mounting base 5. The two sets of the second clamping plates 7 are symmetrically slidably arranged in two sets of second chambers 502 opened on the mounting base 5. Each set of the second clamping plates 7 is fixedly provided with a telescopic rod 14. The telescopic rod 14 is slidably connected to the plug-in cylinder 10 fixedly arranged on the mounting base 5. A second spring 16 is provided in the plug-in cylinder 10. One end of the second spring 16 abuts against the telescopic rod 14, and the other end abuts against the adjustment component.

[0039] Specifically, please refer to Figure 3 , Figure 4 , Figure 8 The aforementioned plug-in cylinder 10 is placed in the through slot 901 opened on the rotating block 9, and the second spring 16 is always in a stretched state, forcing the two sets of second clamping plates 7 to move closer to each other.

[0040] Further, please refer to Figures 1-8Both the first clamping plate 6 and the second clamping plate 7 are fixedly provided with positioning blocks 11, and the positioning blocks 11 are provided with guide slopes 1101. Under the guidance of the guide slopes 1101, the camera can be quickly positioned.

[0041] In detail, the positioning block 11 is configured in the form of a "right-angled trapezoidal structure", with its inclined waist surface configured as a guide slope 1101. A rubber layer is provided on the side of the positioning block 11 facing the axis of the fixed base 2. The rubber layer can increase the friction between the first clamping plate 6 and the second clamping plate 7 and the camera, thereby enhancing the stability of the camera after installation. At the same time, the rubber layer can reduce the clamping damage to the camera caused by the first clamping plate 6 and the second clamping plate 7.

[0042] When installing the camera, with the camera and mounting base 5 coaxial as predicted by the human eye, press the camera downwards. During this process, guided by the guide slope 1101, the camera can force the first clamping plate 6 and the second clamping plate 7 to spread outwards, so that the first spring 12 and the second spring 16 are further stretched, and can quickly become coaxial with the center of the fixed base 2. After the camera contacts the mounting base 5, the reaction force of the first spring 12 and the second spring 16 can clamp the camera inwards, so that the camera is stably fixed on the mounting base 5.

[0043] Furthermore, please refer to Figures 3-8 The rotating seat 3 is also provided with an adjustment component, which is connected to the longitudinal clamping structure. When the adjustment handle 4 is driven to adjust the pitch angle of the camera, the adjustment component can adjust the clamping force of the longitudinal clamping structure.

[0044] Two sets of adjustment components are symmetrically arranged along the circumferential direction of the mounting shaft 301 of the rotating seat 3. Each set of adjustment components includes a driving structure and a moving structure. The moving structure includes a threaded sleeve 17 that is slidably disposed in the insertion cylinder 10. The threaded sleeve 17 is threadedly connected to a lead screw 18 that is rotatably installed in the insertion cylinder 10.

[0045] Specifically, the threaded sleeve 17 is fixedly provided with two sets of sliders 1701 along its circumference. The sliders 1701 are slidably disposed in the grooves 1001 opened on the inner wall of the plug-in cylinder 10. With the cooperation of the sliders 1701 and the grooves 1001, the threaded sleeve 17 can only slide along the axial direction of the plug-in cylinder 10.

[0046] The drive structure includes a drive gear 13 rotatably mounted on the plug-in cylinder 10. The drive gear 13 cooperates with the arc-shaped toothed plate 8 fixedly mounted on the mounting shaft 301 and is connected to the lead screw 18 through the bevel gear set 15.

[0047] The bevel gear set 15 includes a first bevel gear and a second bevel gear. The first bevel gear is coaxially fixed with the drive gear 13, and the second bevel gear is coaxially fixed with the lead screw 18.

[0048] Initially, the camera is at a horizontal angle. At this time, the plug-in tube 10 is as follows: Figure 6 As shown, when it is necessary to adjust the camera's tilt angle, rotate the adjustment handle 4 in the vertical horizontal plane (to...). Figure 6 (For reference only) When the adjustment handle 4 is turned clockwise, the camera tilts to the right and slides to the right under the influence of gravity. During this process, the right drive gear 13 and the right arc-shaped toothed plate 8 engage in a transmission state. Then, with the cooperation of the bevel gear set 15, the lead screw 18 is driven to rotate, thereby forcing the left threaded sleeve 17 to pull the second spring 16 closer to the mounting shaft 301, increasing the clamping force of the right second clamping plate 7 on the camera, thus overcoming the influence of gravity on the camera and preventing the camera from slipping off the mounting base 5.

[0049] Similarly, when the adjustment handle 4 is turned counterclockwise, the left drive gear 13 engages with the left arc-shaped toothed plate 8, and with the cooperation of the bevel gear set 15, drives the lead screw 18 to move, forcing the left threaded sleeve 17 to pull the second spring 16 toward the mounting shaft 301, thereby increasing the clamping force of the left second clamping plate 7 on the camera to prevent the camera from sliding from the left side of the mounting base 5.

[0050] With the cooperation of the aforementioned adjustment components, the stability of the camera mounted on the mounting base 5 can be improved, thereby improving the quality of the captured image, while reducing the risk of the camera slipping off the mounting base 5 when the cameraman is adjusting the angle.

[0051] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
