Description

Technical Field

[0001] This utility model belongs to the technical field of photographic auxiliary equipment, specifically a photographic support slant arm. Background Technology

[0002] A camera slant arm, also known as a slant arm, is a camera rig accessory with adjustable angle and length. It typically consists of one or more joints, allowing photographers to adjust their posture and position as needed. The main function of a slant arm is to support camera lights, reflectors, or other accessories to achieve specific lighting effects or shooting requirements.

[0003] However, traditional angled arms require a large operating force to rotate to a larger angle to release the lock, and even after the angle is adjusted, a large operating force and rotation angle are still required to relock. In addition, traditional angled arms require balanced counterweights at both ends and rely entirely on the screw tightening force to support the angle of the angled arm, which increases the complexity and instability of operation. Therefore, those skilled in the art have proposed a camera bracket angled arm to solve the problems mentioned in the background art.

[0004] The information disclosed above in this background section is only intended to enhance the understanding of the background section of this utility model, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a camera bracket slant arm, which solves the problem in the prior art that the slant arm requires a large operating force to rotate to a larger angle to unlock and relock, and requires balanced matching of weights at both ends.

[0006] To achieve the above objectives, this utility model provides a camera bracket slant arm, including a bracket, the bracket including a support rod, a support base fixedly connected to the end of the support rod, a connecting seat rotatably connected to the support base, a slant arm fixedly connected to the connecting seat, and an angle adjuster provided on the support base, the angle adjuster being fixedly connected to one side of the connecting seat;

[0007] The angle adjuster includes a connecting sleeve fixedly connected to a support base. A fixed shell and a movable shell are symmetrically arranged inside the connecting sleeve. A planetary gear ring is arranged between the fixed shell and the movable shell. A bearing is arranged inside the planetary gear ring. A driving component is arranged inside the fixed shell bushing. A locking component is arranged between the fixed shell bushing and the inner side of the bearing.

[0008] Preferably, the fixed shell has a first toothed groove, the movable shell has a second toothed groove, and the two sides of the planetary gear ring are respectively engaged in the first toothed groove and the second toothed groove. The number of teeth in the first toothed groove is even, the number of outer teeth in the planetary gear ring is odd, and the number of outer teeth in the planetary gear ring is less than the number of teeth in the first toothed groove.

[0009] Preferably, the driving component includes a T-shaped block disposed within the fixed housing bushing, the T-shaped block having an internal spline hole, and a lever fixedly connected to the T-shaped block.

[0010] Preferably, the locking element includes a locking ring disposed between the fixed housing bushing and the inner side of the bearing, the locking ring having a slot and a fixing groove, and a locking spring disposed at the gap between the locking ring, the self-lubricating bearing and the fixed gear housing center bushing.

[0011] Preferably, there are two locking rings arranged symmetrically, the lever is disposed in the slot and the lever is adapted to the slot, and the two free ends of the locking spring are respectively inserted into the fixing slots of the two locking rings.

[0012] Preferably, a rocker arm is rotatably connected inside the fixed housing bushing, and a protrusion is fixedly connected to the end of the rocker arm, the protrusion passing through the inner spline hole.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention utilizes a rocker arm. A protrusion at the end of the rocker arm drives a drive component to rotate via an internal spline hole. As the drive component rotates, a lever on it engages with a locking ring's groove, pushing the locking ring to move. This compresses the locking spring and releases the locking of the planetary gear plate. At this point, the movable shell can be angled relative to the fixed shell. Because the movable shell is fixedly connected to the connecting seat, the connecting seat rotates with the movable shell, causing the angled arm to adjust its angle. The operating force is small, and the rotation angle is moderate, making operation more convenient. The locking spring provides a very precise lock, ensuring the angled arm remains stable at the adjusted angle. Furthermore, the new angled arm has a more optimized structure, resulting in stronger load-bearing capacity. It eliminates the need for counterweights at both ends for balancing, meeting more complex shooting requirements.

[0015] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. It should be noted that the drawings are schematic and not illustrated to scale. For clarity and convenience, the relative sizes and proportions of the parts shown in the drawings have been exaggerated or reduced in size. Any size is only illustrative and not limiting.

[0025] Example:

[0026] Please see Figure 1 - Figure 5As shown, a camera bracket 1 with a slanted arm 14 includes a bracket 1, which includes a support rod 11. A support base 12 is fixedly connected to the end of the support rod 11. A connecting base 13 is rotatably connected to the support base 12. A slanted arm 14 is fixedly connected to the connecting base 13. An angle adjuster 2 is provided on the support base 12 and is fixedly connected to one side of the connecting base 13. The bracket 1 provides support for the whole and supports the support base 12. The support base 12 provides support for the connecting base 13. The connecting base 13 supports the slanted arm 14. The angle adjuster 2 is used to adjust the rotation angle of the slanted arm 14.

[0027] The angle adjuster 2 includes a connecting sleeve 21 fixedly connected to the support base 12. A fixed shell 22 and a movable shell 23 are symmetrically arranged inside the connecting sleeve 21. A planetary gear ring 24 is arranged between the fixed shell 22 and the movable shell 23. A bearing 25 is arranged inside the planetary gear ring 24. A driving component 26 is arranged inside the bushing of the fixed shell 22. A locking component 27 is arranged between the bushing of the fixed shell 22 and the inner side of the bearing 25. The connecting sleeve 21 is used to connect the fixed shell 22 and the movable shell 23 to ensure the relative stability and smooth adjustment between the two. The fixed shell 22 is used as the main support component of the angle adjuster 2. The movable shell 23 can be angled relative to the fixed shell 22. The planetary gear ring 24 is used to drive the movable shell 23 to rotate, thereby realizing the angle adjustment. The bearing 25 is used to reduce the friction and wear of the planetary gear ring 24 when it rotates. The driving component 26 is used to drive the unlocking and locking action of the locking component 27. The locking component 27 is used to lock the planetary gear.

[0028] Specifically, the fixed shell 22 has a first toothed groove 221, and the movable shell 23 has a second toothed groove 231. The planetary gear ring 24 is engaged in the first toothed groove 221 and the second toothed groove 231 on both sides respectively. The number of teeth in the first toothed groove 221 is even, and the number of outer teeth in the planetary gear ring 24 is odd. The number of outer teeth in the planetary gear ring 24 is less than the number of teeth in the first toothed groove 221. Both the first toothed groove 221 and the second toothed groove 231 are used to receive the planetary gear ring 24. The number of outer teeth in the planetary gear ring 24 is one less than the number of teeth in the first toothed groove 221.

[0029] Furthermore, the drive component 26 includes a T-shaped block 261 disposed within the bushing of the fixed housing 22. The T-shaped block 261 has an internal spline hole 262 and a lever 263 is fixedly connected to the T-shaped block 261. The T-shaped block 261 is used to connect with the rocker arm 28, the internal spline hole 262 is used to receive the protrusion 281, and the lever 263 is used to cooperate with the slot 272.

[0030] Furthermore, the locking component 27 includes a locking ring 271 disposed between the bushing of the fixed housing 22 and the inner side of the bearing 25. The locking ring 271 has a slot 272 and a fixing groove 273. A locking spring 274 is disposed in the gap between the locking ring 271, the self-lubricating bearing 25 and the central bushing of the fixed gear housing. The locking ring 271 is used to provide compression force to the locking spring 274. The slot 272 is used to receive the toggle block 263 and the fixing groove 273 is used to receive the locking spring 274. The locking spring 274 is used to lock and unlock the relative position of the planetary gear ring 24 and the fixed housing 22.

[0031] Furthermore, there are two locking rings 271 arranged symmetrically, and the lever 263 is set in the slot 272. The lever 263 is adapted to the slot 272, and the two free ends of the locking spring 274 are respectively inserted into the fixing slots 273 of the two locking rings 271.

[0032] Furthermore, a rocker arm 28 is rotatably connected inside the bushing of the fixed housing 22. A protrusion 281 is fixedly connected to the end of the rocker arm 28. The protrusion 281 passes through the inner spline hole 262. Anti-slip texture is provided on the rocker arm 28. The rocker arm 28 is used to support the protrusion 281 and to drive the protrusion 281 to rotate. The protrusion 281 is used to provide driving force for the drive component 26.

[0033] Working principle: When the angle of the inclined arm 14 is not adjusted, the locking spring 274 presses the two locking rings 271 tightly against the gap between the bearing 25 and the central bushing of the fixed housing 22. The slot 272 on the locking ring 271 and the lever 263 fixedly connected to the T-block 261 are in an uncoordinated state. At this time, the planetary gear plate and the fixed housing 22 are locked, and the movable housing 23 cannot rotate relative to the fixed gear plate. When it is necessary to adjust the angle of the inclined arm 14, the rocker arm 28 is rocked. The protrusion 281 at the end of the rocker arm 28 drives the drive component 26 to rotate through the inner spline hole 262. When the drive component 26 rotates, the lever 263 on it engages with the slot 272 of the locking ring 271, pushing the locking ring 271 to move, thereby compressing the locking spring 274 and releasing the locking of the planetary gear plate. At this time, the movable housing 23 can be angled relative to the fixed housing 22. The connecting seats 13 are fixedly connected, so the connecting seats 13 rotate with the movable shell 23 to drive the angle adjustment of the inclined arm 14. When the inclined arm 14 is adjusted to the required angle, the rotating rocker 28 is stopped, and the locking spring 274 pushes the locking ring 271 to reset under the action of the restoring force. The slot 272 of the locking ring 271 cooperates with the lever 263 of the T-block 261 again to lock the planetary gear plate and the fixed shell 22 in the relative position to ensure the stability of the inclined arm 14. The angle adjuster 2 is set so that the operating force for adjusting the angle of the inclined arm 14 is small and the rotation angle is moderate, making the operation more convenient. The locking spring 274 locks very precisely to ensure that the inclined arm 14 remains stable at the adjusted angle. The new inclined arm 14 is more optimized in structure, making its load-bearing capacity stronger. It does not require the matching balance of the two ends of the counterweight and can meet more complex shooting needs.
