Description

Technical Field

[0001] The invention relates to the technical field of photography auxiliary equipment, and in particular to an angle-variable adapter clamp. 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 of the gimbal are more demanding (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 an adapter clamp with variable angle to solve the technical problems of the traditional gimbal in the prior art, such as high center of gravity (poor stability during shooting) and bulky size (inconvenient to carry).

[0005] The present invention is achieved through the following technical solutions:

[0006] An angle-variable adapter clamp seat, comprising a dovetail groove clamp seat and a hemispherical body fixed at the bottom of the dovetail groove clamp seat;

[0007] It also includes a base, 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 when the hemisphere is not locked, it can swing on the base under the action of external force.

[0008] Furthermore, the base includes a mounting platform which is hollow inside and has an opening on the top, a ball seat is inserted in the opening of the mounting platform, the top surface of the ball seat is recessed downward to form the semi-concave spherical surface, and the mounting platform is provided with a connecting mechanism for connecting the mounting platform, the ball seat and the hemisphere as a whole, and a locking mechanism for pushing the ball seat to lock the hemisphere.

[0009] Furthermore, the connection mechanism includes a connection column 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 connection column extends upward through the opening in turn into the hemisphere;

[0010] A spherical gasket is coupled in the hemisphere, and the spherical gasket is sleeved outside the connecting column. A threaded hole A is opened on the top of the connecting column, and a bolt A is threadedly connected in the threaded hole A for vertically limiting the spherical gasket.

[0011] Furthermore, the locking mechanism 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.

[0012] Furthermore, a through hole is formed through the side of the mounting platform, and the locking member includes a sleeve fixed in the through hole, a bolt B is threadedly connected in the sleeve, the head of the bolt B is located in the mounting platform, the screw portion of the bolt B extends out of the sleeve, and a knob is fixed on the protruding end.

[0013] Furthermore, the locking mechanism also includes an elastic member A installed between the pressure block and the connecting column, 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.

[0014] Furthermore, the bottom wall of the mounting platform protrudes upward to form a protrusion, and the bottom of the ball seat has a groove, and the groove and the protrusion are plug-fitted to limit the circumferential rotation of the ball seat.

[0015] Furthermore, a slide groove is provided on the bottom wall of the mounting platform, and the bottom of the pressing block protrudes downward to form a sliding portion, and the sliding portion slidably cooperates with the slide groove to assist the sliding of the pressing block and limit the circumferential rotation of the pressing block.

[0016] Furthermore, a mounting cavity is provided at the bottom of the dovetail groove clamp seat, and the top of the hemispherical body extends into the mounting cavity and is bolted to the dovetail groove clamp seat.

[0017] Furthermore, a threaded hole B is provided at the bottom of the mounting platform, and the threaded hole B extends upward into the connecting column; a slot is provided at the side of the mounting platform.

[0018] The beneficial effects of the present invention are:

[0019] 1. When the angle-variable adapter 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.

[0020] 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.

[0021] 3. The angle-adapting clamp of the present invention can ensure that the angle-adjusting ability of the adapter clamp is reduced while the volume is reduced by using a hemisphere and slidingly matching the hemi-concave spherical surface of the bowl-shaped ball seat. 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 change the angle by 10-20 degrees to meet the shooting needs of V-log shooters when taking selfies on the desktop or shooting on a slide rail.

[0034] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0035] In the description of the present application, the terms "upper", "lower", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0036] See also Figures 1 to 4The present invention provides a technical solution: an angle-variable adapter clamp, comprising a mounting platform 1 which is hollow inside and has an opening on the top, a threaded hole B12 is provided at the bottom of the mounting platform 1, and the mounting platform 1 can be screwed onto a camera tripod through the threaded hole B12, a card slot 13 is provided on the side of the mounting platform 1, and the mounting platform 1 can be carded through the card slot 13, thereby providing two different mounting methods for the mounting platform 1, thereby improving the adaptability of the mounting platform 1.

[0037] See also Figures 2 to 5 A ball seat 2 is inserted in the opening of the mounting platform 1, and the top surface of the ball seat 2 is recessed downward to form a semi-concave spherical surface 21, and a hemisphere 3 is coupled in the ball seat 2, and the outer spherical surface of the hemisphere 3 is in smooth contact with the semi-concave spherical surface 21, and a dovetail groove clamp seat 4 is fixed on the top of the hemisphere 3, and the dovetail groove clamp seat 4 is used for quick installation of the camera. The dovetail groove clamp seat 4 adopts a universal manual double-slot clamp seat in the prior art, and can also adopt a universal manually tightened single-slot clamp seat, or other quick-release clamp seats or adapter seats in the prior art that can achieve the same purpose, and no excessive restrictions are made in this application document.

[0038] See also Figure 1 and Figure 5 The bottom of the dovetail groove clamp seat 4 is provided with an installation cavity 11, and the top of the hemisphere 3 extends into the installation cavity 11. The installation cavity 11 is used for connecting and installing the hemisphere 3 and the dovetail groove clamp seat 4, and the height of the dovetail groove clamp seat 4 and the hemisphere 3 as a whole can be reduced, thereby reducing the overall volume of the clamp seat. The hemisphere 3 and the dovetail groove clamp seat 4 are fixed by bolts. A level 41 is installed on the bottom wall of the groove body of the dovetail groove clamp seat 4. The level 41 adopts a bubble level 41. By observing whether the bubble is in the center position, it is judged whether the dovetail groove clamp seat 4 is horizontal. Its specific structure and working principle are prior art, and no more details are given here.

[0039] The mounting platform 1 is provided with a connecting mechanism 5 for connecting the mounting platform 1, the ball seat 2 and the hemispherical body 3 as a whole, and a locking mechanism 6 for pushing the ball seat 2 to lock the hemispherical body 3.

[0040] Regarding the connecting mechanism 5:

[0041] See also Figure 2 , Figure 3 , Figure 5 and Figure 6The connecting mechanism 5 includes a connecting column 51 integrally formed at the center of the bottom wall of the mounting platform 1, the hemispherical body 3 is similar to a bowl shape, and the bottoms of the ball seat 2 and the hemispherical body 3 are both open-type designs, and the tops of the connecting columns 51 extend upward through the openings in turn to the hemispherical body 3;

[0042] A spherical gasket 52 is coupled in the hemispherical body 3, and the spherical gasket 52 is sleeved outside the connecting column 51. A threaded hole A53 is opened on the top of the connecting column 51, and the threaded hole A53 extends downward to communicate with the threaded hole B12, and the diameter of the threaded hole A53 is smaller than the diameter of the threaded hole B12 to limit the movable stroke of the corresponding bolt. A bolt A54 for vertically limiting the spherical gasket 52 is threadedly connected in the threaded hole A53, and the spherical gasket 52 can be vertically limited by the bolt A54. The spherical gasket 52, the hemisphere 3, the ball socket 2 and the mounting platform 1 are connected as a whole, and when the bolt A54 is threadedly connected to the connecting column 51, the bolt A54 does not lock the spherical gasket 52, the hemisphere 3 and the ball socket 2, so that when the hemisphere 3 is swung, the hemisphere 3 makes a swinging motion similar to a tumbler between the spherical gasket 52 and the ball socket 2 around the connecting column 51, so as to adjust the angle of the dovetail groove clamp 4 as needed.

[0043] Regarding the locking mechanism 6:

[0044] See also Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8 The locking mechanism 6 includes a pressing block 61 slidably connected to the bottom wall of the mounting platform 1. The pressing block 61 is horseshoe-shaped. The opening of the pressing block 61 faces the connecting column 51. The bottom wall of the mounting platform 1 is provided with a sliding groove 9. The bottom of the pressing block 61 protrudes downward to form a sliding portion 10. The sliding portion 10 slidably cooperates with the sliding groove 9 to assist the sliding of the pressing block 61 and limit the circumferential rotation of the pressing block 61. The bottom wall of the mounting platform 1 protrudes upward to form a protrusion 7. The bottom of the ball seat 2 has a groove 8. The groove 8 is plugged and cooperated with the protrusion 7 to limit the circumferential rotation of the ball seat 2.

[0045] The top of the pressing block 61 and the bottom of the ball seat 2 are respectively provided with inclined surfaces 62, and the pressing block 61 and the ball seat 2 are in smooth contact through the inclined surfaces 62. The mounting platform 1 is provided with a locking member 63 for pushing the pressing block 61 to press the ball seat 2 upward to lock the hemispherical body 3;

[0046] A through hole 631 is formed through the side of the mounting platform 1. The locking member 63 includes a sleeve 632 fixed in the through hole 631. A bolt B633 is threadedly connected in the sleeve 632. The head of the bolt B633 is located in the mounting platform 1. The screw portion of the bolt B633 extends out of the sleeve 632, and a knob 634 is fixed on the extended end.

[0047] The locking mechanism 6 also includes an elastic member A64 installed between the pressure block 61 and the connecting column 51. The elastic member A64 adopts a spring to provide horizontal thrust. Annular grooves 65 are respectively provided on the bottom wall of the mounting platform 1 and the opposite surfaces of the ball seat 2. An elastic member B66 is installed in the annular groove 65. The elastic member B66 is sleeved on the outside of the connecting column 51. The elastic member B66 adopts a circular nitrile rubber ring to provide vertical thrust.

[0048] When the angle-variable adapter clamp of the present invention is used, the mounting platform 1 is fixedly mounted on the camera tripod through the threaded hole B12 or the card slot 13, and then the knob 634 is screwed to move to the side away from the mounting platform 1. Since the bolt B633 is threadedly matched with the sleeve 632, the bolt B633 is driven to rotate synchronously when the knob 634 rotates, and extends out of the mounting platform 1. At this time, the pressing block 61 is not limited by the bolt B633 and is pushed close to the inner wall of the mounting platform 1 under the force generated by the elastic member A64 deforming back to its original shape. After the pressing block 61 moves, the upward thrust on the ball seat 2 is reduced, thereby releasing the locking state between the ball seat 2, the hemisphere 3 and the spherical gasket 52;

[0049] After the locking state is released, since the inner and outer spherical surfaces of the hemisphere 3 are in smooth contact with the spherical surfaces of the ball seat 2 and the spherical gasket 52 respectively, the hemisphere 3 can be moved to swing, so that the hemisphere 3 can make a swinging motion similar to a tumbler around the connecting column 51 between the spherical gasket 52 and the ball seat 2, or the hemisphere 3 can be directly rotated to adjust the angle of the dovetail groove clamp seat 4, thereby adjusting the shooting angle of the camera. By observing the position of the bubble of the level 41, it can be determined whether the dovetail groove clamp seat 4 is in a horizontal state at this time, and the dovetail groove clamp seat 4 can be leveled as needed;

[0050] After the angle adjustment is completed, the knob 634 is screwed in the reverse direction to drive the bolt B633 to push the pressure block 61 to move upward to squeeze the ball seat 2. Under the thrust of the pressure block 61 and the force generated by the deformation of the elastic member B66, the ball seat 2 presses the hemisphere 3 upward against the spherical gasket 52, thereby locking the hemisphere 3. Finally, the camera can be quickly installed on the adapter clamp of the present invention through the dovetail groove clamp 4.

[0051] The angle-adapter clamp of the present invention can ensure that the angle-adjustable adapter clamp has the ability to reduce its volume by slidingly matching the semi-concave spherical surface 21 of the two bowl-shaped ball seats with the hemisphere, and the head of the hemisphere 3 extends into the ball seat 2 and slides with the ball seat 2, and the tail extends into the dovetail groove clamp seat 4, so that the height of the adapter clamp can be further reduced, making the adapter clamp structure more compact and small, so as to lower the center of gravity and ensure stability during shooting. The hemisphere 3 and the ball seat 2 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;

[0052] Secondly, the locking operation of the hemispherical body 3 of the present invention is convenient, and only the knob 634 on the side of the mounting platform 1 needs to be turned.

[0053] 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.
