Description

Technical Field

[0001] This utility model relates to the field of photographic support technology, and in particular to a magic arm. Background Technology

[0002] Magic arms, as a common support tool, are widely used in fields such as cameras, video equipment, and surveillance cameras. Their demand is particularly high in scenarios requiring guidance, adjustment, and stability.

[0003] Currently, most telephoto lenses used in photography employ a toothed mechanism and locking screws to adjust the angle between the lens and the connector. However, the toothed mechanism requires rotating from a locked position to its loosest position to adjust the angle, resulting in insufficient support for the photography equipment during adjustment and even a risk of falling. Furthermore, the toothed mechanism cannot control the angle of the telephoto lens when it is not fully loosened, increasing operation time and making it inconvenient to use. Utility Model Content

[0004] This utility model provides a magic arm to solve the above-mentioned technical problems.

[0005] This utility model is achieved through the following technical solution:

[0006] The magic arm provided in this application includes a first swing arm, a second swing arm, a rotating structure, and a damping structure. One end of the first swing arm is used to connect to a photographic accessory, and one end of the second swing arm is used to connect to a photographic accessory, while the other end is rotatably connected to the other end of the first swing arm. The rotating structure and the damping structure are disposed at the rotatable connection between the first swing arm and the second swing arm. The damping structure is a damping structure for relative rotation between the first swing arm and the second swing arm. The first swing arm and / or the second swing arm are provided with a universal ball structure.

[0007] Optionally, the rotating structure includes a spindle and a spindle sleeve fitted over the spindle; one of the spindle and the spindle sleeve is connected to the first swing arm, and the other is connected to the second swing arm.

[0008] Preferably, the damping structure includes a damping oil receiving cavity formed between the outer wall of the mandrel and the inner wall of the mandrel sleeve, and damping oil contained in the damping oil receiving cavity.

[0009] The omnidirectional ball structure includes a swivel head cover and a ball head installed inside the swivel head cover. The magic arm also includes a locking mechanism for locking the ball head.

[0010] Optionally, the omnidirectional ball joint structure is provided with a locking mechanism, which includes a push rod and an adjusting block. The push rod can move linearly relative to the omnidirectional ball joint in a first direction, and the adjusting block can move linearly relative to the omnidirectional ball joint in a second direction, wherein the first direction is perpendicular to the second direction. One end of the push rod is used to contact the ball head, and the other end of the push rod abuts against the adjusting block and engages with its inclined surface. An operating mechanism is connected to the adjusting block and is used to move the adjusting block linearly in the second direction, thereby applying pressure to the push rod using the inclined surface of the adjusting block to press the push rod against the ball head.

[0011] Preferably, the locking mechanism further includes a spring, one end of which acts on the push rod and the other end of which acts on the swing head sleeve or swing arm. The spring has a tendency to push the push rod against the ball head. When the locking mechanism is unlocked, the spring causes the push rod to push against the ball head to provide a damping function.

[0012] Optionally, the operating mechanism is located at the rotatable connection between the first swing arm and the second swing arm. The operating mechanism includes an adjusting screw and a handle. The adjusting screw is connected to the adjusting block. By rotating the handle, the adjusting screw can be rotated in both directions, thereby causing the adjusting block to move linearly along the first direction.

[0013] Optionally, the adjusting block is threadedly engaged with the adjusting screw.

[0014] Optionally, when both the first and second swing arms are equipped with omnidirectional ball structures, the inclined surfaces of the adjusting blocks of the first and second swing arms are opposite in direction.

[0015] Of the adjusting blocks on the first and second swing arms, one adjusting block is threadedly engaged with the adjusting screw, while the other adjusting block is pushed by a step on the adjusting screw; or both adjusting blocks on the first and second swing arms are threadedly engaged with the adjusting screw, with the threads of the two adjusting blocks in opposite directions.

[0016] Optionally, the first swing arm and / or the second swing arm are provided with threaded holes. The first swing arm and the second swing arm include arm bodies. One end of the arm body of the first swing arm and the second swing arm is connected to an adapter. The other end of the arm body of the first swing arm is rotatably connected to the other end of the arm body of the second swing arm. The threaded holes are provided on the arm bodies. The threaded holes are equipped with detachable threaded connectors.

[0017] Compared with the prior art, this application has at least the following beneficial effects:

[0018] 1. This application enables stepless adjustment of the angles of the two swing arms and hovering at any position without having to rotate from the locked state to the loosest state before rotation, saving operation time; this application allows for easy and quick adjustment and stopping, which is conducive to improving customer experience and increasing customer satisfaction.

[0019] 2. When the locking mechanism of this application is unlocked, the push rod remains pressed against the ball head under the action of the spring, which can play a damping function and prevent the ball head from moving freely without external force.

[0020] 3. When both swing arms have omnidirectional ball structures, the operating mechanism of this application can simultaneously lock and unlock the two omnidirectional ball structures, making operation convenient.

[0021] Of course, implementing any of the solutions of this utility model does not necessarily require achieving all of the advantages described above at the same time. Attached Figure Description

[0033] like Figure 1 , Figure 2 As shown, the magic arm disclosed in this embodiment includes a first swing arm 1, a second swing arm 2, a rotation structure, and a damping structure.

[0034] One end of the first swing arm 1 is the first end, used to connect photographic accessories; the other end of the first swing arm 1 is the second end. One end of the second swing arm 2 is the third end, used to connect photographic accessories; the other end of the second swing arm 2 is the fourth end, which is rotatably connected to the second end. A rotating structure is provided at the rotatable connection between the first swing arm 1 and the second swing arm 2 to realize the rotatable connection between the first swing arm 1 and the second swing arm 2; a damping structure is provided at the rotatable connection between the fourth end and the second end to provide friction.

[0035] Under the action of the damping structure, the first swing arm 1 and the second swing arm 2 can rotate relative to each other to any angle position and stop. The magic arm stops rotating through the damping structure, which can realize the installation needs of photography accessories from multiple angles and directions.

[0036] The damping structure includes a damping oil receiving cavity 30 located between the opposing sidewalls at the rotatable connection of the first swing arm 1 and the second swing arm 2, and the damping oil receiving cavity 30 is filled with damping oil. The damping of the damping oil fixes the relative rotation angle between the first swing arm 1 and the second swing arm 2, and the damping oil allows for stepless adjustment of the rotation angle.

[0037] Optionally, in some embodiments, please refer to Figure 3 , Figure 4 The rotating structure includes a spindle 31 and a spindle sleeve 32 sleeved outside the spindle 31. One of the spindle 31 and the spindle sleeve 32 is connected to the first swing arm 1, and the other is connected to the second swing arm 2.

[0038] The damping oil receiving cavity 30 is formed between the outer wall of the spindle 31 and the inner wall of the spindle sleeve 32. Under the action of external force, the spindle sleeve 32 can rotate with the spindle 31 as the axis, thereby adjusting the angle between the first swing arm 1 and the second swing arm 2; after the external force is removed, the spindle sleeve 32 and the spindle 31 can be relatively stationary under the action of damping, realizing the arbitrary suspension of the first swing arm 1 and the second swing arm 2.

[0039] Please see Figure 5 In an exemplary embodiment, a groove 311 is provided on the outer sidewall of the mandrel 31, and the groove 311 and the inner sidewall of the mandrel sleeve 32 together form a damping oil receiving cavity 30. In other embodiments, a groove 311 is provided on the inner sidewall of the mandrel sleeve 32, and the groove 311 and the outer sidewall of the mandrel 31 together form a damping oil receiving cavity 30. Alternatively, grooves 311 are provided at corresponding positions on the outer sidewall of the mandrel 31 and the inner sidewall of the mandrel sleeve 32, and the grooves 311 of the mandrel 31 and the grooves 311 of the mandrel sleeve 32 together form a damping oil receiving cavity 30.

[0040] In some embodiments, the magic arm of this application may have damping oil brushed onto the spindle 31 at the factory; customers may also install damping oil themselves as needed.

[0041] In an exemplary embodiment, the mandrel 31 is connected to the first swing arm 1, and the mandrel sleeve 32 is connected to the second swing arm 2. Preferably, the mandrel 31 is connected to the first swing arm 1 via a connecting sleeve 33. For more details, please refer to... Figure 3 , Figure 5 The spindle 31 has a bayonet 312. One end of the connecting sleeve 33 is fixedly connected to the first swing arm 1, and the other end of the connecting sleeve 33 has a locking block 331 that matches the bayonet 312. The locking block 331 is engaged in the bayonet 312. The circumferential positioning of the connecting sleeve 33 and the spindle 31 is achieved through the cooperation of the locking block 331 and the bayonet 312, preventing the connecting sleeve 33 and the first swing arm 1 from rotating relative to the spindle 31. Preferably, the connecting sleeve 33 is screwed to the first swing arm 1, and the spindle sleeve 32 is screwed to the second swing arm 2.

[0042] Optionally, in this embodiment, both the first swing arm 1 and the second swing arm 2 are provided with a universal ball structure 4 to achieve omnidirectional deflection, meeting the multi-angle shooting requirements of the magic arm. In other embodiments, one of the first swing arm 1 and the second swing arm 2 is provided with a universal ball structure 4, which can also achieve omnidirectional connection of the magic arm. Therefore, in this application, the number and placement of the universal ball structures 4 are not limited.

[0043] Please see Figure 2 In an exemplary embodiment, the omnidirectional ball structure 4 includes a swivel head sleeve 41 and a ball head 42, with the ball head 42 housed within the swivel head sleeve 41. The omnidirectional ball structure 4 is equipped with a locking mechanism. The specific structure of the locking mechanism is not limited.

[0044] In some embodiments, the locking mechanism includes a push rod 51 and an adjusting block. The push rod 51 can move linearly relative to the swing arm in a first direction, and the adjusting block can move linearly relative to the swing arm in a second direction, the first direction being perpendicular to the second direction. One end of the push rod 51 is used to contact the ball head 42, and the other end of the push rod 51 abuts against the adjusting block and engages with its inclined surface 50. The operating mechanism 7 is connected to the adjusting block and is used to move the adjusting block linearly in the second direction, using the inclined surface of the adjusting block to push the push rod 51 to tighten the ball head 42.

[0045] Preferably, the locking mechanism also includes a spring 53. One end of the spring 53 acts on the push rod 51, and the other end of the spring 53 acts on the swing head sleeve 41 or the swing arm. The spring 53 has a tendency to make the push rod 51 press against the ball head 42. When the locking mechanism is unlocked, the spring 53 makes the push rod 51 still press against the ball head 42 to play a damping function and prevent the ball head 42 from moving freely without external force.

[0046] Optionally, in some embodiments, the operating mechanism 7 is located at the rotatable connection between the first swing arm 1 and the second swing arm 2. The operating mechanism 7 includes an adjusting screw 71 and a handle 72. The adjusting screw 71 is connected to the adjusting block. By rotating the handle 72, the adjusting screw 71 can be driven to rotate in both directions, thereby driving the adjusting block to move linearly along the first direction.

[0047] Please see Figure 2In an exemplary embodiment, both the first swing arm 1 and the second swing arm 2 have a universal ball structure 4. A first adjusting block 52 is mounted on the second end, and the first adjusting block 52 is linearly slidably connected to the first swing arm 1. A second adjusting block 53 is mounted on the fourth end, and the second adjusting block 53 is linearly slidably connected to the second swing arm 2. A push rod 51 is mounted on both the first swing arm 1 and the second swing arm 2. The inclined surfaces of the adjusting blocks of the first swing arm 1 and the second swing arm 2 are opposite in direction. One end of the push rod 51 is used to contact the ball head 42. The other end of the push rod 51 of the first swing arm 1 abuts against the first adjusting block 52 and engages with its inclined surface 50. The other end of the push rod 51 of the second swing arm 2 abuts against the second adjusting block 53 and engages with its inclined surface 50. The first adjusting block 52 is fitted onto the adjusting screw 71 and threadedly engaged with it. The other end of the adjusting screw 71 is connected to a handle 72. A step on the adjusting screw 71 is used to push the second adjusting block 53.

[0048] When the handle 72 is turned in the forward direction, the adjusting screw 71 is rotated in the forward direction, which in turn causes the first adjusting block 52 and the second adjusting block 53 to move towards each other in the first direction. The first adjusting block 52 and the second adjusting block 53 apply pressure to the two push rods 51 through their inclined surfaces, so that the push rods 51 press against the corresponding ball heads 42, and the ball heads 42 are locked. When the handle 72 is turned in the reverse direction, the adjusting screw 71 is rotated in the reverse direction, which in turn causes the first adjusting block 52 and the second adjusting block 53 to move away from each other in the first direction. When they contact the pressure of the first adjusting block 52 and the second adjusting block 53 on the push rods 51, the ball heads 42 are unlocked.

[0049] Optionally, a bearing 73 is provided between the second adjusting block 53 and the adjusting screw 71. Optionally, a linear groove 11 is provided on the first swing arm 1 and the second swing arm 2, and a slider 54 adapted to the linear groove 11 is provided on the first adjusting block 52 and the second adjusting block 53. The slider 54 is installed in the linear groove 11 to realize the linear sliding constraint on the first adjusting block 52 and the second adjusting block 53.

[0050] Preferably, the mandrel 31 is loosely fitted outside the first adjusting block 52.

[0051] As described above, the adjusting screw 71 pushes the second adjusting block 53 to move through its step. However, the present invention is not limited to this. In some other embodiments, the second adjusting block 53 is also threadedly connected to the adjusting screw 71, and the threads of the second adjusting block 53 are opposite to those of the first adjusting block 52.

[0052] In some embodiments, the magic arm further includes a wire clamp 8, which may be disposed on the first swing arm 1 or the second swing arm 2, or on the top rod 51. It is worth noting that the specific structure of the wire clamp 8 is not limited in this application. The position and number of the wire clamp 8 are also not limited.

[0053] Of course, the first end of the first swing arm 1 and the third end of the second swing arm 2 are respectively provided with adapters 6 for connecting and installing photographic accessories.

[0054] It should be noted that the specific structure of the adapter 6 is not limited in this application. The adapter 6 can also be any adapter method such as a quick-release base or an adapter hole.

[0055] In some embodiments, such as Figure 6 As shown, the adapter 6 includes a quick-release base 61 and a quick-release plate 62. The quick-release base 61 has a latch 63 and a button 64. The button 64 is used to control the latch 63 to switch between the unlocked and locked positions. The quick-release plate 62 is detachably mounted on the quick-release base 61. The quick-release plate 62 has a locking position that matches the latch 63. When the latch 63 is in the unlocked position, the quick-release plate 62 can be separated from the quick-release base 61. When the latch 63 is in the locked position, the latch 63 can be locked in the locking position of the quick-release plate 62, so that the quick-release plate 62 is locked to the quick-release base 61.

[0056] Optionally, Arri locating pins 65 are provided on the quick-release plate 62.

[0057] Optionally, the quick-release plate 62 has a threaded connecting post 66. Preferably, the threaded connecting post 66 is a 1 / 4 screw post.

[0058] As a preferred option, the quick-release plate 62 is the F22 quick-release plate.

[0059] In some embodiments, the Arri positioning pin 65 is retractable to meet the fixing requirements of different devices.

[0060] In some embodiments, such as Figure 1 As shown, the first swing arm 1 and / or the second swing arm 2 are provided with threaded holes 12. The first swing arm 1 and the second swing arm 2 include arm bodies. One end of the arm body of the first swing arm 1 and the second swing arm 2 is connected to an adapter 6, and the other end of the arm body of the first swing arm 1 is rotatably connected to the other end of the arm body of the second swing arm 2. The threaded holes 12 are provided on the arm bodies. The threaded holes 12 are equipped with detachable threaded connectors (not shown in the figure), through which photographic accessories can be installed on the arm bodies. Of course, the diameter of the threaded holes 12 of the first swing arm 1 and the second swing arm 2 can be different. Preferably, the threaded holes 12 are 1 / 4" screw holes or 3 / 8" screw holes.

[0061] In some embodiments, the threaded hole 12 on the first swing arm 1 is a 1 / 4 screw hole, and the threaded hole 12 on the second swing arm 2 is a 3 / 8 screw hole.

[0062] In some embodiments, both the first swing arm 1 and the second swing arm 2 have 1 / 4 screw holes or 3 / 8 screw holes.

[0063] In some embodiments, the threaded connecting post 66 has a threaded hole that is adapted to the threaded connecting post 66. For example, the threaded hole 12 is a 3 / 8 screw hole, and the threaded hole 12 is equipped with a 3 / 8 threaded connector; the threaded connecting post 66 is a 1 / 4 screw post, and the 3 / 8 threaded connector has a 1 / 4 screw hole, so that the 3 / 8 threaded connector can be installed on the threaded connecting post 66, thereby changing the 1 / 4 screw post on the quick-release plate 62 into a 3 / 8 threaded connector, thus adapting to different models of photographic accessories.

[0064] Pressing button 61 allows the quick-release plate 62 to be removed and the device to be secured, eliminating the need for overall fixation and making switching convenient. The quick-release base 61 and quick-release plate 62 are secured by latch 63, enabling one-click quick release.

[0065] This application enables stepless adjustment of the angles of the two swing arms and hovering at any position, without requiring rotation from the locked state to the loosest state before rotation can occur. This saves operation time, improves ease of use, enhances customer experience, and increases customer satisfaction.

[0066] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
