Description

Technical Field

[0001] The invention relates to the technical field of photography auxiliary equipment, and in particular to a panoramic clamping seat with adjustable angle. Background Art

[0002] When shooting on a slide rail, tripod or V-log, photographers usually need a gimbal with adjustable angles, and install a quick-release plate at the bottom of the camera, and then clamp the gimbal on the quick-release plate at the bottom of the camera to assist in shooting. However, for slide rail shooting and V-log shooting, the camera's viewing angle is fixed most of the time, and usually does not require a large angle change. An angle change of 10-20 degrees can meet more than 95% of shooting needs. In these shooting occasions, the large angle change function of the gimbal is not a rigid demand (burdensome), but the height and volume requirements of the gimbal are more stringent (rigid demand).

[0003] For example, the spherical gimbal in the prior art is basically more than 6-7 cm in height, has a high center of gravity, is bulky, and has poor stability during shooting. Especially in the process of sliding rail shooting, the disadvantage of the high center of gravity of the gimbal is particularly serious. The slightest jitter during the operation of the sliding rail will be extremely magnified due to the high center of gravity of the gimbal, resulting in the production of waste films. At the same time, due to its large size, it is not very convenient to carry and use when shooting in specific occasions. For example, many V-log shooters directly screw the handle to the bottom of the camera and abandon the gimbal adapter because of the heavy gimbal. However, if the gimbal adapter is not used, it is inconvenient to use when shooting on a sliding rail or V-log (especially when taking V-log selfies on a desktop) because the camera angle cannot be adjusted. Therefore, how to reduce the height and volume of the gimbal while ensuring that the angle is appropriately adjustable (just enough to use) to provide photographers with a lightweight and compact clamp to meet the needs of the consumer market segment is an urgent problem to be solved by technical personnel in this field. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a panoramic clamp with adjustable angle to solve the technical problems in the prior art that the camera gimbal is large in size, has a high center of gravity, and has poor stability during shooting.

[0010] Furthermore, a connecting hole with a stepped cross-section is provided through the top and bottom of the dovetail groove clamp seat, and a connecting column A is integrally formed at the top center of the turntable, the top of the connecting column A extends into the connecting hole, and a threaded hole A is provided on the top of the connecting column A, and a bolt A is threadedly connected in the threaded hole A for connecting the turntable and the dovetail groove clamp seat as a whole.

[0011] Furthermore, the top of the base has a semi-concave spherical surface, the outer spherical surface of the hemisphere is in smooth contact with the semi-concave spherical surface, and the base is provided with a locking mechanism for locking the hemisphere;

[0012] The base comprises a mounting platform which is hollow inside and has an opening on the top, a ball seat is inserted into the opening of the mounting platform, and the top surface of the ball seat is concave downward to form the semi-concave spherical surface;

[0013] The locking mechanism comprises a connecting component for connecting the mounting platform, the ball seat and the hemisphere as a whole, and a pushing component for pushing the ball seat to lock the hemisphere.

[0014] Further, the connecting component includes a connecting column B integrally formed at the center of the bottom wall of the mounting platform, the hemisphere is bowl-shaped, and the bottom of the ball seat and the hemisphere are both open-type designs, and the top of the connecting column B extends upward through the opening in turn into the hemisphere;

[0015] A spherical gasket is coupled in the hemisphere, and the spherical gasket is sleeved outside the connecting column B. A threaded hole B is provided on the top of the connecting column B, and a bolt B is threadedly connected in the threaded hole B for vertically limiting the spherical gasket.

[0016] Furthermore, the pushing component includes a pressure block slidably connected to the bottom wall of the mounting platform, the top of the pressure block and the bottom of the ball seat are respectively provided with inclined surfaces, and the mounting platform is provided with a locking member for pushing the pressure block upward to squeeze the ball seat to lock the hemisphere.

[0017] Furthermore, a through hole is formed through the side of the mounting platform, and the locking member includes a sleeve B fixed in the through hole, a bolt C is threadedly connected in the sleeve B, the head of the bolt C is located in the mounting platform, the screw portion of the bolt C extends out of the sleeve B, and a knob is fixed on the protruding end.

[0018] Furthermore, the pushing component also includes an elastic member A installed between the pressure block and the connecting column B, and an annular groove is respectively provided on the bottom wall of the mounting platform and the opposite surface of the ball seat, and an elastic member B is installed in the annular groove, and the elastic member B is sleeved outside the connecting column B.

[0019] Furthermore, the top surface of the turntable is provided with a positioning ring groove, and the top wall of the accommodating cavity protrudes downward to form a positioning piece, and the positioning piece is plug-fitted with the positioning ring groove.

[0020] The beneficial effects of the present invention are:

[0021] 1. When the angle-adjustable panoramic clamp of the present invention is in use, the locking mechanism is loosened to release the locking state between the hemisphere and the ball seat. After the locking state is released, the inner and outer spherical surfaces of the hemisphere are in smooth contact with the spherical surfaces of the ball seat and the spherical gasket respectively, so that the hemisphere can be moved to swing, so that the hemisphere can make a swinging motion similar to a tumbler around the connecting column between the spherical gasket and the ball seat, or the hemisphere can be directly moved to rotate to adjust the angle of the dovetail groove clamp, thereby adjusting the shooting angle of the camera.

[0022] 2. By observing the position of the bubble on the spirit level, it can be determined whether the dovetail groove clamp is in a horizontal state at this time. The dovetail groove clamp can be leveled as needed. After the angle adjustment is completed, the hemisphere can be locked by rotating the knob in the opposite direction. Finally, the camera can be quickly installed on the adapter clamp of the present invention through the dovetail groove clamp.

[0023] 3. The angle-adjustable panoramic clamp of the present invention can ensure that the adapter clamp has the ability to adjust the angle while reducing the volume by using a hemisphere and the semi-concave spherical surface of the bowl-shaped ball seat to slide together, and the head of the hemisphere extends into the ball seat and slides with the ball seat, and the tail extends into the dovetail groove clamp seat, so that the height of the adapter clamp seat can be further reduced, making the adapter clamp seat structure more compact and small, so as to lower the center of gravity and ensure stability during shooting. The hemisphere and the ball seat can swing to an angle change of 10-20 degrees to meet the shooting needs of V-log shooters when taking selfies on the desktop or shooting on a slide rail.

[0024] 4. During the shooting process, when it is necessary to rotate the camera to accurately adjust the shooting angle of the camera, the sleeve B is twisted outward through the handle, and the sleeve B moves toward the outside of the dovetail groove clamp seat. When the sleeve B moves, it drives the push rod to move, thereby releasing the abutment lock of the push rod head on the locking piece and the turntable. At this time, the dovetail groove clamp seat can rotate freely relative to the turntable, and the rotation angle of the dovetail groove clamp seat can be intuitively observed through the scale on the outer surface of the hemisphere, thereby accurately rotating and adjusting the shooting angle of the camera.

[0053] Regarding the angle adjustment mechanism 6:

[0054] See also Figures 1 to 6 The angle adjustment mechanism includes a hemispherical body 61 fixedly connected to the turntable 3 by bolts, and a base 62 coupled to the hemispherical body 61, the top of the base has a semi-concave spherical surface 63, the outer spherical surface of the hemispherical body 61 is in smooth contact with the semi-concave spherical surface 63, and the base 62 is provided with a locking mechanism for locking the hemispherical body;

[0055] The base 62 includes a mounting platform 621 which is hollow inside and has an opening on the top. A threaded hole C12 is provided at the bottom of the mounting platform 621. The mounting platform 621 can be screwed onto a camera tripod through the threaded hole C12. A card slot 13 is provided on the side of the mounting platform 621. The mounting platform 621 can be carded through the card slot 13, thereby providing two different mounting methods for the mounting platform 621, thereby improving the adaptability of the mounting platform 621. A ball seat 622 is inserted into the opening of the mounting platform 621. The top surface of the ball seat 622 is concave downward to form the semi-concave spherical surface 63.

[0056] The locking mechanism includes a connecting component 65 for connecting the mounting platform 621 , the ball seat 622 and the hemispherical body 61 as a whole, and a pushing component 66 for pushing the ball seat 622 to lock the hemispherical body 61 .

[0057] Regarding the connecting part 65:

[0058] See also Figure 3 , Figure 4 and Figure 6 The connecting component 65 includes a connecting column B651 integrally formed at the center of the bottom wall of the mounting platform 621, the hemispherical body 61 is similar to a bowl shape, and the bottom of the ball seat 622 and the hemispherical body 61 are both open-type designs, and the top of the connecting column B651 extends upward through the opening in turn into the hemispherical body 61;

[0059] A spherical gasket 652 is coupled in the hemispherical body 61, and the spherical gasket 652 is sleeved outside the connecting column B651. A threaded hole B653 is opened on the top of the connecting column B651, and the threaded hole B653 extends downward to communicate with the threaded hole B653, and the diameter of the threaded hole B653 is smaller than the diameter of the threaded hole B653 to limit the movable stroke of the corresponding bolt. A bolt B654 for vertically limiting the spherical gasket 652 is threadedly connected in the threaded hole B653, and the spherical gasket 652 can be vertically limited by the bolt B654. The gasket 652, the hemisphere 61, the ball seat 622 and the mounting platform 621 are connected as a whole, and when the bolt B654 is threadedly connected to the connecting column B651, the bolt B654 does not lock the spherical gasket 652, the hemisphere 61 and the ball seat 622, so that when the hemisphere 61 is swung, the hemisphere 61 can make a swinging motion similar to a tumbler between the spherical gasket 652 and the ball seat 622 around the connecting column B651, so as to adjust the angle of the dovetail groove clamp 1 as needed.

[0060] Regarding the pushing member 66:

[0061] See also Figure 1 , Figure 4 , Figure 6 , Figure 7 and Figure 8 The pushing component 66 includes a pressing block 661 slidably connected to the bottom wall of the mounting platform 621. The pressing block 661 is horseshoe-shaped. The opening of the pressing block 661 faces the connecting column B651. The bottom wall of the mounting platform 621 is provided with a sliding groove 10. The bottom of the pressing block 661 protrudes downward to form a sliding portion 11. The sliding portion 11 slidably cooperates with the sliding groove 10 to assist the pressing block 661 in sliding and limit the circumferential rotation of the pressing block 661. The bottom wall of the mounting platform 621 protrudes upward to form a protrusion 8. The bottom of the ball seat 622 has a groove 9. The groove 9 is plugged and cooperated with the protrusion 8 to limit the circumferential rotation of the ball seat 622.

[0062] The top of the pressing block 661 and the bottom of the ball seat 622 are respectively provided with inclined surfaces 662, and the pressing block 661 and the ball seat 622 are in smooth contact through the inclined surfaces 662. The mounting platform 621 is provided with a locking member 663 for pushing the pressing block 661 to press the ball seat 622 upward to lock the hemispherical body 61;

[0063] A through hole 6631 is formed through the side of the mounting platform 621. The locking member 663 includes a sleeve B6632 fixed in the through hole 6631. A bolt C6633 is threadedly connected in the sleeve B6632. The head of the bolt C6633 is located in the mounting platform 621. The screw rod of the bolt C6633 extends out of the sleeve B6632, and a knob 6634 is fixed on the extended end.

[0064] The pushing component 66 also includes an elastic member A664 installed between the pressure block 661 and the connecting column B651. The elastic member A664 adopts a spring to provide horizontal thrust. Annular grooves 665 are respectively provided on the bottom wall of the mounting platform 621 and the opposite surfaces of the ball seat 622. An elastic member B666 is installed in the annular groove 665. The elastic member B666 is sleeved on the outside of the connecting column B651. The elastic member B666 adopts a circular nitrile rubber ring to provide vertical thrust.

[0065] When the angle-adjustable panoramic clamp of the present invention is in use, the mounting platform 621 is fixedly mounted on the camera tripod through the threaded hole C12 or the card slot 13, and then the knob 6634 is screwed to move to the side away from the mounting platform 621. Since the bolt C6633 is threadedly matched with the sleeve B6632, the bolt C6633 is driven to rotate synchronously when the knob 6634 rotates, and extends out of the mounting platform 621. At this time, since the pressing block 661 is not limited by the bolt C6633 and is pushed close to the inner wall of the mounting platform 621 under the force generated by the elastic member A664 deforming back to its original shape, the pressing block 661 reduces the upward thrust on the ball seat 622 after moving, thereby releasing the locking state between the ball seat 622, the hemisphere 61 and the spherical gasket 652;

[0066] After the locking state is released, since the inner and outer spherical surfaces of the hemisphere 61 are in smooth contact with the spherical surfaces of the ball seat 622 and the spherical gasket 652 respectively, the hemisphere 61 can be moved to swing, so that the hemisphere 61 can make a swinging motion similar to a tumbler around the connecting column B651 between the spherical gasket 652 and the ball seat 622, or the hemisphere 61 can be directly rotated to adjust the angle of the dovetail groove clamp 1, thereby adjusting the shooting angle of the camera. By observing the position of the bubble of the level 7, it can be determined whether the dovetail groove clamp 1 is in a horizontal state at this time, and the dovetail groove clamp 1 can be leveled as needed;

[0067] After the angle adjustment is completed, the knob 6634 is screwed in the reverse direction to drive the bolt C6633 to push the pressure block 661 to move and squeeze the ball seat 622 upward. Under the thrust of the pressure block 661 and the force generated by the deformation of the elastic member B666, the ball seat 622 presses the hemisphere 61 upward against the spherical gasket 652, thereby locking the hemisphere 61. Finally, the camera can be quickly installed on the panoramic gimbal of the present invention through the dovetail groove clamp 1.

[0068] When the camera is rotated to adjust the shooting angle of the camera, the sleeve B6632 is screwed outwardly through the handle 544, and the sleeve B6632 moves toward the outside of the dovetail groove clamp 1. When the sleeve B6632 moves, it drives the push rod 543 to move, thereby releasing the abutment lock of the push rod 543 head on the locking piece 53 and the turntable 3. At this time, the dovetail groove clamp 1 can rotate freely relative to the turntable 3, and the rotation angle of the dovetail groove clamp 1 can be intuitively observed through the scale on the outer surface of the hemisphere 61, thereby accurately rotating and adjusting the shooting angle of the camera; after the angle adjustment is completed, the handle 544 is screwed in the opposite direction to make the push rod 543 push the locking piece 53, and the locking piece 53 swings close to the turntable 3 through the relative rotation between the rotating shaft 52 and the sealing plate 51, and abuts against the turntable 3, thereby locking the dovetail groove clamp 1 and the turntable 3 with each other.

[0069] The angle-adjustable panoramic clamp of the present invention can ensure that the panoramic clamp has the ability to adjust the angle while reducing the volume by using a hemisphere 61 and the semi-concave spherical surface 63 of the bowl-shaped ball seat 622 to slide together, and the head of the hemisphere 61 extends into the ball seat 622 and slides with the ball seat 622, and the tail extends into the dovetail groove clamp 1, so as to further reduce the height of the panoramic head, making the panoramic head structure more compact and small, so as to lower the center of gravity and ensure stability during shooting. The hemisphere 61 and the ball seat 622 can swing to an angle change of 10-20 degrees to meet the shooting needs of V-log shooters when taking selfies on the desktop or shooting on a slide rail;

[0070] Secondly, the locking operation of the hemispherical body 61 of the present invention is convenient, and only the knob 6634 on the side of the mounting platform 621 needs to be turned.

[0071] Finally, it should be noted that the above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention are within the scope of protection required by the present invention.
