DETAILED DESCRIPTION

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inward" and "outward" refer to directions toward or away from the geometric center of a particular component, respectively.

[0031] See also Figures 1-8 , the present invention provides four technical solutions: Example 1

[0032] See also Figure 1 In an embodiment of the present invention, a three-axis adjustable panoramic shooting gimbal includes a base 1, a concave seat 2 for damped rotation on the upper part of the base 1, and limit rollers 3 for damped rotation on the inner sides of both ends of the concave seat 2. An outer ring seat 4 is connected between the opposite ends of the two limit rollers 3, and an inner ring seat 5 for damped rotation is passed through the interior of the outer ring seat 4. The interior of the inner ring seat 5 is a hollow structure, and two groups of positioning mechanisms 6 are provided on the inner ring seat 5. The two groups of positioning mechanisms 6 are located on both sides of the axis of the inner ring seat 5, and shooting auxiliary mechanisms 8 for light blocking adjustment of the camera lens are provided at both ends of the concave seat 2.

[0033] In the above scheme: by rotating the concave seat 2, the horizontal rotation of the camera is adjusted, then the outer ring seat 4 is rotated to adjust the longitudinal rotation of the camera, and then the inner ring seat 5 is rotated to adjust the left and right rotation of the camera, to achieve three-axis adjustment and ensure the quality of shooting.

[0034] The second embodiment differs from the first embodiment in that:

[0035] See also Figure 1 and Figure 2In the embodiment of the present invention, the positioning mechanism 6 includes two gears 61 rotatably arranged on the end face of one side of the inner ring seat 5, and the two gears 61 are meshed with each other. One end of one gear 61 is located in the hollow structure inside the inner ring seat 5 and is connected to a limiting shaft 62. The end of the limiting shaft 62 away from the gear 61 rotates through the hollow structure inside the inner ring seat 5 and is connected to a knob 63. The outside of the limiting shaft 62 is located in the hollow structure inside the inner ring seat 5 and is provided with a flange 64. The outside of the limiting shaft 62 is located in the hollow structure inside the inner ring seat 5 and is provided with a torsion spring 65. The two ends of the torsion spring 65 are respectively connected to one side of the flange 64 and the inner wall of the hollow structure inside the inner ring seat 5. A convex plate 66 is provided on one side of the two gears 61. A positioning roller 67 is provided on the side of the end of the two convex plates 66 away from the gear 61. The positioning roller 67 passes through the interior of the inner ring seat 5.

[0036] In the above scheme: before passing the camera lens through the inner ring seat 5, turn the knob 63 to drive the limit shaft 62 to rotate, thereby driving the gear 61 to rotate, and the gear 61 drives the other gear 61 meshing with it to rotate, so that the convex plates 66 on one side of the two gears 61 move away from each other, thereby making the two positioning rollers 67 move away from each other, and when the knob 63 is rotated, the other knob 63 of the driving member 9 rotates, thereby driving the other group of two positioning rollers 67 away from each other, and then the camera lens is passed through the interior of the inner ring seat 5, and then the knob 63 is released. Under the elasticity of the torsion spring 65, the limit shaft 62 will be reset, so that the two positioning rollers 67 are close to each other, so that the four positioning rollers 67 will clamp the two sides of the camera, achieve clamping in different directions, and have the effect of positioning and fixing the camera.

[0037] For further information, see Figure 1 and Figure 2 In the embodiment of the present invention, the inner diameter of the inner ring seat 5 is larger than the outer diameter of the camera lens. When the torsion spring 65 is in the reset state, the distance between the positioning rollers 67 on the two sets of positioning mechanisms 6 is smaller than the outer diameter of the camera lens. When the positioning rollers 67 on the two sets of positioning mechanisms 6 are opened, the distance between the four positioning rollers 67 is larger than the outer diameter of the camera lens, which facilitates the lens to pass through the inner ring seat 5 and then position and clamp the lens.

[0038] For further information, see Figure 1 and Figure 2 as well as Figure 3 In an embodiment of the present invention, the three-axis adjustable panoramic photography gimbal further includes a driving member 9 for simultaneously driving the two positioning mechanisms 6 to work. The driving member 9 includes a transmission wheel 1 91 respectively arranged on the outside of the two knobs 63 and two transmission wheels 2 92 respectively rotatably arranged at the upper and lower parts of the side of the inner ring seat 5 away from the gear 61. The transmission wheel 1 91 and the transmission wheel 2 92 are connected by a belt 93. When the knob 63 is rotated, the transmission wheel 1 91 is driven to rotate, and the transmission wheel 1 91 is driven by the belt 93.

[0039] It should be added that: the limiting shafts 62 on the two sets of positioning mechanisms 6 are fixed on one of the gears 61 and the other on the other gear 61. In this way, under the transmission of the belt 93, the two positioning rollers 67 on the two positioning mechanisms 6 will open or merge at the same time to complete the positioning and clamping work.

[0040] For further information, see Figure 1 and Figure 2 In the embodiment of the present invention, a layer of rubber pad is bonded to the outside of the positioning roller 67. The rubber pad is soft to prevent the lens housing from being damaged by clamping.

[0041] The third embodiment differs from the first embodiment in that:

[0042] See also Figure 1 and Figure 2-Figure 8 In the embodiment of the present invention, movable grooves 7 are provided inside both ends of the concave seat 2, and the movable grooves 7 extend to the upper end surface and one side end surface of one end of the concave seat 2. The shooting auxiliary mechanism 8 includes a worm gear 81 rotatably provided inside the movable groove 7, and a worm 82 is engaged with the lower side of the worm gear 81. One end of the worm gear 82 rotates through the inner wall of the movable groove 7 and is connected to a handle 83. A connecting member 84 is connected to one side of the worm gear 81, and the end of the connecting member 84 away from the worm gear 81 passes through the movable groove 7 and is provided with a plate body 85.

[0043] See also Figure 1 and Figure 2-Figure 8 In the embodiment of the present invention, the connecting member 84 includes a limiting cylinder 841 connected to one side of the worm gear 81, and an opening is provided at one end of the limiting cylinder 841 away from the worm gear 81, and a hollow bar 847 is hinged in the opening. The other end of the hollow bar 847 extends out of the opening and is embedded in a movable shaft 8410 that is horizontally slidably installed. A strip-shaped card slot 851 is provided inside one side of the plate body 85, and a sliding groove communicating with the card slot 851 is provided on one side of the plate body 85. A plurality of positioning grooves 852 are equidistantly provided on the inner side of the card slot 851. The movable shaft 8410 is located between one end of the hollow bar 847 and the inner wall of the hollow bar 847 through a spring 2 8415. The movable shaft 84 The other end of 10 is inserted into the card slot 851 through the sliding slot and is clamped in the positioning slot 852, and can rotate in the positioning slot 852. The upper part of the end of the hollow bar 847 away from the limiting cylinder 841 is provided with a limiting slot 8412 which is communicated with the interior of the hollow bar 847. The inner side wall of the limiting slot 8412 is hinged with a pressing plate 8413, and the lower side of the pressing plate 8413 is hinged with a connecting rod 8414. The other end of the connecting rod 8414 is hinged to the upper side of the movable shaft 8410. When the spring 2 8415 is in the reset state, the end of the pressing plate 8413 away from its hinge point is tilted upward, so that the movable shaft 8410 is driven to slide toward the interior of the hollow bar 847 when the pressing plate 8413 is pressed.

[0044] In the above scheme: when shooting, the handle 83 is turned to drive the worm 82 to rotate, the worm 82 drives the worm gear 81 meshing with it to rotate, the worm gear 81 drives the connecting member 84 to swing, and then drives the plate 85 to move, so that the plate 85 moves to one side of the camera lens, and then the other plate 85 is moved to the other side of the camera lens in the same way, and then the pressing plate 8413 is pressed. Under the elasticity of the second spring 8415, the pressing plate 8413 drives the connecting rod 8414 to drive the moving shaft 8410 toward the inner direction of the hollow bar 847, so that one end of the moving shaft 8410 leaves the positioning groove 852 inside the card slot 851 and enters the card slot 851. At this time, the plate 85 can be slid to move the moving shaft 8410. One end of 410 slides in the card slot 851 inside the plate body 85 to adjust the height of the plate body 85. After adjustment, release the button 8413, and the spring 2 8415 resets the movable shaft 8410, so that one end of the movable shaft 8410 is inserted into the corresponding positioning slot 852. Then rotate the plate body 85, so that the plate body 85 will rotate on one end of the movable shaft 8410 to adjust the light-blocking angle of the plate body 85, and the elastic gasket 853 inside the positioning slot 852 acts as a damping agent for the rotation of the movable shaft 8410, so that after the angle of the plate body 85 is adjusted, the plate body 85 will remain in the adjusted position. Then use the same method to adjust the light-blocking position of the other plate body 85, thereby blocking the light for the lens.

[0045] For further information, see Figure 1 and Figure 2-Figure 8 In the embodiment of the present invention, an elastic gasket 853 is provided on the inner wall of the positioning groove 852, and the end of the movable shaft 8410 away from the spring 2 8415 is tapered, which is convenient for insertion into the positioning groove 852. When the end is inserted into the positioning groove 852, the elastic gasket 853 fits tightly on the end face of the movable shaft 8410, so that when the movable shaft 8410 rotates in the positioning groove 852, it plays a damping role. When the rotation stops, the plate body 85 will not be offset.

[0046] For further information, see Figure 1 and Figure 2-Figure 8 In the embodiment of the present invention, one end of the movable shaft 8410 is located in the card slot 851 and is provided with a second flange 8411 that is adapted to its internal dimensions. When one end of the movable shaft 8410 leaves the positioning slot 852, the one end of the movable shaft 8410 will not be separated from the card slot 851 due to the obstruction of the second flange 8411.

[0047] The fourth embodiment differs from the first embodiment in that:

[0048] See also Figure 1 and Figure 2-Figure 8In the embodiment of the present invention, a strip groove 842 communicating with the interior of the limiting cylinder 841 is provided on the upper part of one end close to the hollow bar 847, and a shift rod 843 is inserted in the strip groove 842. The lower end of the shift rod 843 is located in the limiting cylinder 841 and is connected to the moving cylinder 844. The inner wall of the limiting cylinder 841 is connected to the guide rod 845. The moving cylinder 844 is horizontally slidably sleeved on the outside of the guide rod 845, and a spring 846 is sleeved on the outside of the guide rod 845. The two ends of the spring 846 are respectively connected to one end of the moving cylinder 844 and the inner wall of the limiting cylinder 841.

[0049] See also Figure 1 and Figure 2-Figure 8 In the embodiment of the present invention, the end face of the hollow bar 847 close to the limiting cylinder 841 and the side surface are respectively provided with a second positioning hole 849 and a first positioning hole 848 that are compatible with the moving cylinder 844. When the second positioning hole 849 or the first positioning hole 848 corresponds to the moving cylinder 844 and the spring 1 846 is in the reset state, the end of the moving cylinder 844 away from the spring 1 846 passes through the limiting cylinder 841 and is inserted into the second positioning hole 849 or the first positioning hole 848.

[0050] In the above scheme: when it rains, turn the handle 83 to move the connecting piece 84 to a vertical state, then move the lever 843 to make the movable cylinder 844 slide on the guide rod 845, so that one end of the movable cylinder 844 is disengaged from the positioning hole 2 849 on the hollow bar 847, then rotate the hollow bar 847 to the top of the outer ring seat 4, and make the positioning hole 1 848 correspond to the movable cylinder 844, after the correspondence, release the lever 843, the spring 1 846 will reset the movable cylinder 844, and one end of the movable cylinder 844 will be inserted into the positioning hole 1 848 on the hollow bar 847, then adjust the position of the plate 85 in the same way as adjusting the light blocking, so that the plate 85 is in a horizontal state, and the opposite sides of the two plates 85 are merged together, which can protect the camera lens from rain.

[0051] Working principle: before passing the camera lens through the inner ring seat 5, turn the knob 63 to drive the limit shaft 62 to rotate, thereby driving the gear 61 to rotate, and the gear 61 drives the other gear 61 meshing with it to rotate, so that the convex plates 66 on one side of the two gears 61 move away from each other, thereby making the two positioning rollers 67 move away from each other, and when the knob 63 is rotated, it drives the transmission wheel 1 91 to rotate, and the transmission wheel 1 91 drives another knob 63 to rotate through the belt 93, thereby driving the other group of two positioning rollers 67 to move away from each other, then pass the camera lens through the inside of the inner ring seat 5, and then release the knob 63. Under the elasticity of the torsion spring 65, the limit shaft 62 will be reset, so that the two positioning rollers 67 are close to each other, so that the four positioning rollers 67 will clamp the two sides of the camera, realize clamping in different directions, and have the effect of positioning and fixing the camera;

[0052] When shooting, by rotating the concave seat 2, adjust the horizontal rotation of the camera, then rotate the outer ring seat 4 to adjust the longitudinal rotation of the camera, and then rotate the inner ring seat 5 to adjust the left and right rotation of the camera, achieving three-axis adjustment to ensure the quality of shooting;

[0053] When shooting, the handle 83 is turned to drive the worm 82 to rotate, and the worm 82 drives the worm gear 81 meshing with it to rotate, and the worm gear 81 drives the connecting piece 84 to swing, thereby driving the plate 85 to move, so that the plate 85 moves to one side of the camera lens. Then, the other plate 85 is moved to the other side of the camera lens in the same way. Then, the pressing plate 8413 is pressed. Under the elasticity of the second spring 8415, the pressing plate 8413 drives the connecting rod 8414 to drive the moving shaft 8410 toward the inner direction of the hollow bar 847, so that one end of the moving shaft 8410 leaves the positioning groove 852 inside the card slot 851 and enters the card slot 851. At this time, the plate 85 can be slid to move the moving shaft 8410. One end of the plate 85 slides in the card slot 851 inside the plate 85 to adjust the height of the plate 85. After the adjustment, the pressing plate 8413 is released, and the spring 8415 resets the movable shaft 8410, so that one end of the movable shaft 8410 is inserted into the corresponding positioning slot 852. Then, the plate 85 is rotated, so that the plate 85 rotates on one end of the movable shaft 8410 to adjust the light blocking angle of the plate 85. The elastic gasket 853 inside the positioning slot 852 damps the rotation of the movable shaft 8410, so that after the angle of the plate 85 is adjusted, the plate 85 will remain in the adjusted position. Then, the same method is used to adjust the light blocking position of the other plate 85, thereby blocking the lens from light.

[0054] When it rains, turn the handle 83 to move the connecting piece 84 to a vertical state, then move the lever 843 to make the movable cylinder 844 slide on the guide rod 845, so that one end of the movable cylinder 844 is disengaged from the positioning hole 2 849 on the hollow bar 847, then rotate the hollow bar 847 to the top of the outer ring seat 4, and make the positioning hole 1 848 correspond to the movable cylinder 844, after the correspondence, release the lever 843, and the spring 1 846 will reset the movable cylinder 844, and one end of the movable cylinder 844 will be inserted into the positioning hole 1 848 on the hollow bar 847, then adjust the position of the plate 85 in the same way as adjusting the light blocking, so that the plate 85 is in a horizontal state, and the opposite sides of the two plates 85 are merged together, which can protect the camera lens from rain.
