Description

A photographic device Technical Field

[0001] This invention belongs to the field of photographic equipment technology, and specifically relates to a photographic device. Background Technology

[0002] Currently, users often employ rotating shooting techniques during photography to achieve desired effects. However, the applicant has found that existing rotating shooting methods either require the user to carry the camera equipment while rotating and shooting, which is physically demanding, results in unstable rotation control, and severely impacts the shooting quality; or the camera equipment is mounted on a tripod, requiring the user to stand beside the tripod while shooting. During rotating shooting, the user must manually rotate the camera equipment while simultaneously walking around the tripod, making operation extremely inconvenient and posing a safety hazard of tripping over the tripod or other objects, while also affecting the shooting quality. Summary of the Invention

[0003] To address the aforementioned problems in the prior art, the present invention provides a photographic apparatus.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] The photographic apparatus of the present invention includes a seat and a rotating connecting arm; wherein,

[0006] The seat includes a seat cushion and legs. The top of the legs is provided with a swivel bearing seat, and the seat cushion is assembled and connected to the swivel bearing seat so that the seat cushion can be rotatably mounted on the top of the legs.

[0007] The lower end of the rotating connecting arm is assembled and connected to the rotating bearing seat, and has a locked state and an unlocked state. In the locked state, the rotating connecting arm rotates together with the seat cushion. In the unlocked state, the rotating connecting arm can rotate around the seat cushion and adjust its relative position with the seat cushion.

[0008] The above technical solution enables the camera equipment and the seat to rotate synchronously, achieving rotational shooting without the need to rotate the camera equipment separately. This makes shooting operations convenient, improves the stability of the camera equipment during rotational shooting, and ensures that the relative position between the user and the camera equipment remains unchanged.

[0044] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0045] The photographic device of the present invention includes a seat 100 and a rotating connecting arm 200; the seat 100 includes a seat cushion 101 and a leg 102, the top of the leg 102 is provided with a rotating bearing seat 103, and the seat cushion 101 is assembled and connected to the rotating bearing seat 103 so that the seat cushion 101 is rotatably mounted on the top of the leg 102.

[0046] The lower end of the rotating connecting arm 200 is assembled and connected to the rotating bearing seat 103, and has a locked state and an unlocked state. In the locked state, the rotating connecting arm 200 rotates together with the seat cushion 101. In the unlocked state, the rotating connecting arm 200 can rotate around the seat cushion 101 and adjust its relative position with the seat cushion 101.

[0047] Examples 1 and 2

[0048] As shown in Figures 1-12, the photographic device described in Embodiments 1 and 2 of the present invention includes a seat 100 and a rotating connecting arm 200.

[0049] The seat portion 100 includes a seat cushion 101 and a leg portion 102. A rotating bearing seat 103 is provided at the top of the leg portion 102. The seat cushion 101 is assembled and connected to the rotating bearing seat 103, allowing the seat cushion 101 to be rotatably mounted on the top of the leg portion 102. Specifically, the rotating bearing seat 103 has a bearing 104 and a connecting post 105 at its top. The upper end of the connecting post 105 is connected to the seat cushion 101, as shown in Figure 3. The seat cushion 101 is fixed to the upper end face of the connecting post 105 by screws. The lower end of the connecting post 105 is assembled on the bearing 104 and connected to a locking member 106 that passes through the bearing 104 from bottom to top. Preferably, the connecting post 105 is cylindrical.

[0050] The lower end of the rotating connecting arm 200 is assembled and connected to the rotating bearing seat 103, and has a locked state and an unlocked state. Specifically, the lower end of the rotating connecting arm 200 is assembled on the connecting post 105, and the locking and unlocking states are switched via the locking member 106, as shown in Figures 2-4. The lower end of the rotating connecting arm 200 is provided with a rotating locking position 201, which is assembled on the connecting post 105, allowing the rotating connecting arm 200 to rotate around the connecting post 105. The locking member 106 drives the connecting post 105 and the seat 101 to move downwards synchronously, working together with the bearing 104 to clamp the rotating connecting arm 200. When locked, the connecting post 105 and the seat 101 are moved upward synchronously by the locking member 106, switching the rotating connecting arm 200 to the locked state. The rotating connecting arm 200 includes a transverse connecting arm 207 and a longitudinal connecting arm 206. The lower end of the longitudinal connecting arm 206 is connected to one end of the transverse connecting arm 207 in an L-shape. The other end of the transverse connecting arm 207 is provided with the rotating locking position 201, which is assembled and connected to the rotating bearing seat 103. The locking member 106 can be a screw with an operating part. The lower end of the connecting post 105 has an internal threaded hole. The screw passes through the bearing 104 and is screwed into the internal threaded hole.

[0051] When using the photographic device described in this embodiment of the invention, the user can lock the rotating connecting arm 200 by operating the locking member 106 (i.e., the rotating connecting arm 200 is in a locked state). At this time, the rotating connecting arm 200 rotates together with the seat cushion 101, driving the camera and other photographic equipment 400 installed on the rotating connecting arm 200 to rotate synchronously, realizing rotating shooting. There is no need to rotate the photographic equipment separately, making the shooting operation more convenient. It also improves the stability of the movement of the photographic equipment 400 during the rotating shooting process, and ensures that the relative position between the user and the photographic equipment 400 remains unchanged, thereby improving the shooting quality and the capture efficiency of the camera lens (quickly capturing the photographic image). It can also ensure the safety of the user during the rotating shooting process, reduce fatigue, and improve comfort.

[0052] Furthermore, users can unlock the rotating connecting arm 200 by operating the locking member 106 according to the actual shooting environment and shooting needs (the rotating connecting arm 200 is in the unlocked state). The rotating connecting arm 200 can rotate around the seat cushion 101 and adjust its relative position to the seat cushion 101 (as shown in Figures 1, 4, 5, 7, 10), which expands the applicability of the photography device and makes it more flexible and convenient to use.

[0053] Preferably, the rotating locking position 201 is a U-shaped latch, which is located at the lower end of the rotating connecting arm 200. The U-shaped latch is directly engaged with the connecting post 105, and then the locking member 106 is tightened to complete the assembly of the rotating connecting arm 200 and the seat part 100. This operation is simple, convenient, and quick. Furthermore, the distance between the rotating connecting arm 200 and the seat cushion 101 can be adjusted by changing the distance of the U-shaped latch engaging with the connecting post 105, thus adapting to the usage requirements of different users and further enhancing the flexibility of the photographic device.

[0054] More preferably, the lower edge of the U-shaped latch extends inward to form a protruding edge 202, making the diameter of the lower end of the U-shaped latch smaller than the outer diameter of the connecting post 105. In the locked state, the protruding edge 202 is clamped between the connecting post 105 and the bearing 104, as shown in Figure 3. This further improves the stability and robustness of the rotating connecting arm 200.

[0055] As shown in Figure 3, in order to further improve assembly convenience and stability, the upper surface of the bearing 104 described in Embodiments 1 and 2 of the present invention is provided with a groove 115, and the lower end of the connecting column 105 is provided with a connecting part 107. The connecting part 107 is coaxial with the connecting column 105, and the connecting part 107 is matchedly installed in the groove 115 and connected to the locking member 106.

[0056] Furthermore, the locking member 106 is also provided with a spring 116, the two ends of which abut against the locking member 106 and the bearing 104, respectively. The spring 116 generates an upward force on the locking member 106, thereby improving the unlocking performance of the locking member 106.

[0057] As shown in Figures 1 and 4-12, the photographic device described in Embodiments 1 and 2 of the present invention further includes a photographic boom 300. When the rotating connecting arm 200 is rotated and adjusted to be located on the left or right side of the seat 101, the photographic boom 300 can be installed on the upper end of the rotating connecting arm 200. The photographic boom 300 has a photographic equipment mounting base 313, which is used to install the photographic equipment 400. For example, the photographic equipment mounting base 313 can be a camera screw, used to directly install the camera or to install a gimbal and then install the camera. The photographic equipment mounting base 313 can also be a quick-release clamp, used to directly install the camera. The camera boom 300 includes a first boom 303, a second boom 304, and a third boom 305. The first boom 303 is mounted on the upper end of the rotating connecting arm 200. The second boom 304 is arranged laterally, with one end connected to the front end of the first boom 303 and the other end provided with a camera equipment mounting base 313. Furthermore, to make the camera boom 300 suitable for mounting on the rotating connecting arm 200 which rotates to the left and right sides of the seat 101, the front end of the first boom 303 is provided with an upper mounting base 301 and a lower mounting base 302, so that... The second boom 304 is assembled and connected to the upper mounting base 301 and the lower mounting base 302, which can be connecting bases with internal threaded holes. The second boom 304 is assembled to the front end of the first boom 303 by a screw. One end of the third boom 305 is connected to the rear end of the first boom 303 and is provided with a counterweight 306. The counterweight 306 includes a counterweight block 307 and a connecting rod 308. The counterweight block 307 is located at the rear end of the connecting rod 308. The front end of the connecting rod 308 is telescopically and lockingly inserted into the rear end of the first boom 303.

[0058] Furthermore, the second boom 304 and the first boom 303 are rotatably connected, and the third boom 305 is axially folded to the first boom 303. Specifically, one end of the second boom 304 is laterally rotatably connected to the front end of the first boom 303, and the front end of the third boom 305 is folded upwards to fold into connection with the rear end of the first boom 303. When not in use, the second boom 304 is rotated to be in a straight line with the first boom 303 (or rotated to overlap with the first boom 303), and the third boom 305 is axially flipped to overlap with the first boom 303 and the second boom 304. This significantly reduces the size and space occupied by the photography boom 300, reducing product packaging and transportation costs, facilitating storage, and making it more convenient to carry. Furthermore, to improve the folding effect, a folding connection portion 309 is provided between the front end of the third boom 305 and the rear end of the first boom 303. The two ends of the folding connection portion 309 are rotatably connected to the third boom 305 and the first boom 303, respectively. Moreover, the rear end of the first boom 303 and the front end of the third boom 305 are respectively provided with a first clearance position 310 and a second clearance position 311, so that the rear end of the first boom 303 and the third boom 305 fold more closely. The folding connection portion 309 is also provided with a positioning protrusion 312 to limit the unfolding angle between the first boom 303 and the third boom 305, ensuring the counterweight performance of the third boom 305.

[0059] As shown in Figures 10-12, in Embodiment 2 of the present invention, the camera boom 300 is rotatably mounted on the upper end of the rotating connecting arm 200 (specifically, the first boom 303 of the camera boom 300 is rotatably mounted on the upper end 315 of the longitudinal connecting arm 206 of the rotating connecting arm 200 via a pivot 314), and an angle adjustment structure is provided between them. The angle adjustment structure includes a turntable 203 and a quick-lock bolt 315; the turntable 203 is installed on the upper end of the rotating connecting arm 200. The camera boom 300 is equipped with arc-shaped or ring-shaped locking positions 204. The quick-lock bolt 315 is horizontally and axially movable on the camera boom 300. When adjusting the angle of the camera boom 300, the quick-lock bolt 315 can be pulled away from the turntable 203 until its inner end separates from the locking position 204. After the camera boom 300 angle adjustment is completed, the quick-lock bolt 315 can automatically reset towards the turntable 203, moving its inner end into the corresponding locking position 204. This angle adjustment structure allows for adjustment of the pitch angle of the camera boom 300, thereby adjusting the shooting angle of the camera equipment 400. Compared to existing angle adjustment structures that require repeated screw tightening, this adjustment operation is convenient and quick.

[0060] Preferably, the outer end of the quick-lock bolt 301 has an operating part 316, and the operating part 316 is provided with a locking slot 317. When the quick-lock bolt 315 can automatically reset and move to its inner end and the corresponding locking slot 204 in the direction of the turntable 203, the locking slot 317 locks the camera boom 300, avoiding the risk of the quick-lock bolt 315 and the locking slot 204 accidentally loosening, and the safety of use is high.

[0061] As shown in Figures 1, 4, 6, and 10, the upper end of the rotating connecting arm 200 described in Embodiments 1 and 2 of the present invention is further provided with a first connector 205. The first connector 205 can be used to install the photographic equipment 400. For example, the first connector 205 can be a camera screw for directly installing the camera or for installing a gimbal and then installing the camera. The first connector 205 can also be a quick-release clamp for directly installing the camera.

[0062] The seat cushion 101 is connected to a backrest 108, which is detachable from the seat cushion 101. The first connector 205 can also be assembled with the backrest 108 detached from the seat cushion 101 to form a workbench. Specifically, the rear end of the seat cushion 101 has a first latching part 110 with two latching holes 111 on the left and right. The lower end of the backrest 108 has a second latching part 112 with two telescopic latching posts 113 on the left and right, respectively detachably fitted into the two latching holes 111. The back of the backrest 108 has a second connector 114, which is assembled onto the first connector 205 to form the workbench. This allows users to assemble the photography equipment 400 on the workbench, reducing the risk of dropping the equipment and improving the convenience and safety of assembling it. It also eliminates the need for an additional workbench, making it more convenient to carry and store.

[0063] As shown in Figures 1, 5-7, 10, and 11, the upper end of the longitudinal connecting arm 206 described in Embodiments 1 and 2 of the present invention has a telescopic arm 208. The user can adjust the height of the telescopic arm 208 as needed, thereby adjusting the shooting height of the photography equipment 400 or adjusting the height of the worktable formed by the backrest 108. The specific structure can be as follows: the upper end of the longitudinal connecting arm 206 is provided with a socket (not shown in the figure), the lower end of the telescopic arm 208 is movably installed in the socket, and the upper outer wall of the longitudinal connecting arm 206 is also provided with a locking screw 209. One end of the locking screw 209 passes through the outer wall of the longitudinal connecting arm 206, extends into the socket, and abuts against the telescopic arm 208 to lock the telescopic arm 208.

[0064] Furthermore, the locking screw 209 has a locking pressure plate 210 at its abutting end, which improves the locking performance of the telescopic arm 208 on the one hand, and prevents the telescopic arm 208 from being crushed or scratched on the other.

[0065] As shown in Figures 1-5, 7, 9, and 10, the leg 102 described in Embodiments 1 and 2 of the present invention further includes three support legs 109. These three support legs 109 are arranged in a circular array and mounted on a rotating bearing seat 103. The upper ends of the three support legs 109 are rotatably connected to the rotating bearing seat 103. In use, the three support legs 109 are in an extended supporting state; in non-use, they are in a closed state. This makes the photographic device easy to carry and more convenient for outdoor use. The support legs 109 are telescopic tubes, allowing for height adjustment based on usage needs and allowing for adjustment of the length of each support leg 109 according to the terrain of the environment, thus adjusting the photographic device (seat 101) to a horizontal position. Example 3

[0066] As shown in Figures 13 and 14, the photographic device described in Embodiment 3 of the present invention has a structure that is basically the same as that in Embodiments 1 and 2, including a seat 100 and a rotating connecting arm 200. The only difference is that the photographic device includes two or more upper rotating connecting arms 200, at least one of which has a photographic boom 300 mounted on its upper end, and at least one of which has a first connector 205 at its upper end. The first connector 205 is used to mount the photographic equipment 400, or to assemble with the backrest 108 detached from the seat cushion 101 to form a worktable. In this way, the photographic device is more powerful and easier to use. Example 4

[0067] As shown in Figures 15 and 16, the photographic device described in Embodiment 4 of the present invention has a structure that is basically the same as that in Embodiments 1 to 3, including a seat 100 and a rotating connecting arm 200. The difference is that the rotating connecting arm 200 is provided with a support part 211, which supports the rotating connecting arm 200 on the ground or other positions, thereby improving the load-bearing capacity of the rotating connecting arm 200 and the balance of the photographic device. Preferably, the support part 211 is a telescopic rod, whose length can be adjusted to meet the support requirements of the usage environment, making it highly adaptable. The support portion 211 has a third latching portion 212 at its upper end, and the front end of the rotating connecting arm 200 has a fourth latching portion 213. The third latching portion 212 and the fourth latching portion 213 are detachably assembled and connected. Specifically, the third latching portion 212 is a T-shaped latch head, and the fourth latching portion 213 is a side-mounted T-shaped latch groove. During assembly, the T-shaped latch head is installed inside the T-shaped latch groove. Preferably, the fourth latching portion 213 is located at the connection between the longitudinal connecting arm 206 and the transverse connecting arm 207, as shown in Figure 16. The fourth latching portion 213 is located at one end of the transverse connecting arm 207. During assembly, the support portion 211 and the longitudinal connecting arm 206 are located on the same straight line, which is beneficial to improving the support performance. Of course, the third snap-fit ​​part 212 can also be an external threaded connector, and correspondingly, the fourth snap-fit ​​part 213 is an internal threaded hole. During assembly, the external threaded connector is installed in the internal threaded hole; or, the third snap-fit ​​part 212 can also be a snap-fit ​​head with an elastic snap-fit ​​bead, and the fourth snap-fit ​​part 213 is a snap-fit ​​hole with a snap-fit ​​position on the inner wall. During assembly, the snap-fit ​​head is snapped in the snap-fit ​​hole, and the elastic snap-fit ​​bead is snapped in the snap-fit ​​position.

[0068] Furthermore, as shown in Figure 15, the three supporting feet 109 of the leg 102 described in Embodiment 4 of the present invention are all straight tubes with wheels 117, making the camera device easier to move and particularly advantageous for use on flat ground indoors and outdoors.

[0069] The above description represents the preferred embodiments of the present invention.
