The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.
Referring to fig. 1, the present invention provides a shooting assistance device 100, in which the shooting assistance device 100 can be installed with a shooting device and a shooting assistance device to assist the shooting device to shoot. The photographing apparatus may be any electronic apparatus having a camera, such as a camera, a mobile phone, a tablet computer, and the like, and the photographing auxiliary device may be a monitor, a photographing lamp, a microphone, a flash lamp, and the like. The auxiliary photographing device 100 provided by the invention is a portable type, the portable type is provided with a device body 110, the device body 110 is a handheld part of the portable type, and the handheld part can be held by a hand of a person to finish photographing operation. It is understood that in other embodiments, the shooting assistance device 100 may also be, but is not limited to, a shooting assistance handle, a support stand, a camera rabbit cage, or the like. The device body 110 at this time may be understood as a handle body, a support body and a rabbit cage body, respectively.
The shooting assisting device 100 comprises a device body 110 and a rotating structure 200, wherein the device body 110 can be provided with a first mounting part 101, the rotating structure 200 can be provided with a second mounting part 102, the first mounting part 101 and the second mounting part 102 can be respectively used for mounting shooting equipment and shooting assisting equipment, and the first mounting part 101 and the second mounting part 102 can be but are not limited to a quick mounting seat, a threaded connector, a threaded hole and the like. The apparatus body 110 is rotatable about the rotation axis of the rotation structure 200, so that the photographing device or the photographic assistant equipment of the apparatus body 110 at the first mounting portion 101 can be rotated relative to the rotation structure 200.
Fig. 1 also illustrates that the rotating structure 200 is slidable along the length extending direction of the apparatus body 110, so that the height of the second mounting portion 102 provided at the end of the rotating structure 200 can be switched. When the rotating structure 200 needs to be slid, the screw between the rotating structure 200 and the device body 110 can be loosened, and then slid to the preset position along the length direction of the device body 110, and when the rotating structure 200 slides to the preset position, the screw is tightened to fix the rotating structure 200 to the preset position. It is understood that in other embodiments, the rotating structure 200 may be configured not to slide vertically relative to the apparatus body 110.
Referring to fig. 2 and 3, the rotating structure 200 includes a main body 300 and a locking assembly 400. The main body 300 includes a sleeve 310 and a rotating rod 320, the rotating rod 320 rotatably penetrates the sleeve 310 along the circumference of the sleeve 310, and bearings 321 may be respectively disposed at two ends of the rotating rod 320 to improve the centering of the rotating rod 320 during rotation. It can be understood that the sleeve 310 is provided with a rotation groove 311, and the rotation rod 320 is inserted into the rotation groove 311. The end of the sleeve 310 far away from the rotating rod 320 is connected with the device body 110, the end of the rotating rod 320 far away from the sleeve 310 is used for being connected with the shooting device through the second mounting part 102 arranged at the tail end of the rotating rod 320, and when the rotating rod 320 rotates along the circumferential direction, the rotating rod 320 can carry the shooting device to switch angles in the circumferential direction. In other embodiments, the sleeve 310 is connected to the photographing apparatus, and the rotating lever 320 is connected to the device body 110.
The locking assembly 400 includes a first locking member 410 and a second locking member 420, and the first locking member 410 and the second locking member 420 can be switched between a locking position and an unlocking position. When the first locking element 410 and the second locking element 420 are in the respective locking positions, the rotating rod 320 is circumferentially limited to the sleeve 310, and it can be understood that the rotating rod 320 cannot complete the circumferential rotation relative to the sleeve 310.
It is to be understood that when the first locking member 410 is in the unlocked position and the second locking member 420 is in the locked position, the rotating rod 320 can rotate in the forward direction, and the second locking member 420 limits the rotation of the rotating rod 320 in the reverse direction. At this time, it can be understood that the rotating rod 320 cannot perform the reverse rotation action in the circumferential direction relative to the sleeve 310, that is, the rotating rod 320 can rotate in the forward direction in one direction, but the rotating rod 320 cannot rotate in the reverse direction. It should be noted that "forward" and "reverse" described in the embodiments of the present invention are relative terms, and when "forward" is understood as clockwise, "reverse" can be understood as counterclockwise. When "forward direction" is understood to be counterclockwise, "reverse direction" is understood to be clockwise.
When the first locking element 410 is in the locked position and the second locking element 420 is in the unlocked position, the rotating rod 320 can rotate in the reverse direction, and the first locking element 410 limits the rotation of the rotating rod 320 in the forward direction. At this time, it can be understood that the rotating rod 320 cannot perform the forward rotation action relative to the sleeve 310 along the circumferential direction, that is, the rotating rod 320 can rotate in the reverse direction in one direction, but the rotating rod 320 cannot rotate in the forward direction.
When the first locking member 410 is in the unlocked position and the second locking member 420 is in the unlocked position, the rotation of the rotary lever 320 in the forward direction is released, and the rotation of the rotary lever 320 in the reverse direction is also released. It is understood that the rotary lever 320 can be selectively driven to rotate in the forward direction or in the reverse direction.
It should be emphasized that the above-described inability of the rotary lever 320 to rotate in a forward direction or the inability of the rotary lever 320 to rotate in a direction is not an absolute limitation and should be broadly construed herein. That is, the rotation of the rotation lever 320 in the forward direction is not allowed, and it can be understood that the frictional resistance of the rotation lever 320 in the forward direction is too large, and as long as the force for driving the rotation lever 320 is large enough, the rotation lever 320 can be rotated in the forward direction, which may cause a great deal of effort. Similarly, the rotation of the rotary lever 320 in the reverse direction is not limited to the rotation of the rotary lever 320 in the reverse direction, and the rotation of the rotary lever 320 in the reverse direction may be achieved by the friction resistance of the rotary lever 320 in the reverse direction.
In the auxiliary photographing device 100 according to the embodiment of the present invention, one of the rotating rod 320 and the sleeve 310 may be connected to a photographing apparatus, and the other may be connected to a racket aid handle or a supporting frame, since the first locking element 410 and the second locking element 420 may respectively control the rotating rod 320 to rotate in two different directions (forward or reverse, which may be understood as clockwise or counterclockwise), that is, the rotation of the photographing apparatus relative to the racket aid handle or the supporting frame is achieved. During the actual use process, the user can selectively operate the first locking element 410 or the second locking element 420 according to the actual use requirement or the operation and use habit matched with the user. For example, when the user desires the rotation lever 320 to adjust the photographing orientation of the photographing apparatus by rotating in a forward direction, the first locking member 410 may be switched to the unlocked position, and when the user desires the rotation lever 320 to adjust the photographing orientation of the photographing apparatus by rotating in a reverse direction, the second locking member 420 may be switched to the unlocked position. On the foregoing basis, if the user does not wish to rotate the rotary lever 320 in the other, opposite direction, the other locking element is simultaneously switched to the locking position to restrict the rotation of the rotary lever 320. Therefore, the invention provides a user to selectively decide whether the rotating rod 320 rotates forwards or backwards so as to meet the shooting use requirements of different photographers, and the invention has the advantages of practicability, flexibility, compact integral structure, small occupied space and convenient assembly and disassembly.
For a clearer understanding of the present invention regarding the independent manipulation of the first locking element 410 and the second locking element 420 to achieve the forward rotation or the reverse rotation of the rotating rod 320, reference will be made to the following, and the present invention will be described in detail herein.
Referring to fig. 4 and 5, the first locking element 410 includes a first protrusion 411 between the sleeve 310 and the rotating rod 320, and the second locking element 420 includes a second protrusion 421 between the sleeve 310 and the rotating rod 420, the second protrusion 421 being circumferentially spaced from the first protrusion 411. The first protrusion 411 and the second protrusion 421 can be driven by an external force to move close to or away from each other along the circumferential direction, and when the first protrusion 411 and the second protrusion 421 move close to each other, at least one of the first locking element 410 and the second locking element 420 is switched to the unlocking position, at which the circumferential limit of the rotating rod 320 is released to rotate relative to the sleeve 310. When the first protrusion 411 and the second protrusion 421 are away from each other, parts (rollers described below) of the first locking element 410 and the second locking element 420 respectively abut against the rotating rod 320 to limit circumferential rotation thereof.
In this embodiment, the locking assembly 400 further includes a limiting member 430 and an elastic member 440 disposed between the first protrusion 411 and the second protrusion 421, the limiting member 430 includes a first roller 431 and a second roller 432 circumferentially arranged, and the first roller 431 and the second roller 432 are located between the sleeve 310 and the rotating rod 320. The elastic member 440 is disposed between the first roller 431 and the second roller 432, the elastic member 440 is in a compressed state, and the elastic force accumulated by the compressed elastic member 440 tends to drive the first roller 431 and the second roller 432 to move toward the two ends. It is understood that, in other embodiments, the elastic member 440 may not be disposed between the first roller body 431 and the second roller body 432, for example, the elastic member 440 may include a first elastic body disposed between the first protrusion 411 and the first roller body 431, and a second elastic body disposed between the second protrusion 421 and the second roller body 432, the first elastic body and the second elastic body being in a stretched state and accumulating an elastic force. It should be noted that the elastic member 440 and the elastic body may include, but are not limited to, a spring, and an elastic rubber pad, and the embodiment is a spring.
When the first locking member 410 and the second locking member 420 are in the respective locking positions, the first roller 431 and the second roller 432 are respectively abutted against the rotating rod 320 by the elastic force released by the elastic member 440 in opposite directions, and at this time, if the rotating rod 320 rotates in the forward direction, a frictional resistance is generated between the rotating rod 320 and the first roller 431 and between the rotating rod 320 and the second roller 432, the frictional resistance between the rotating rod 320 and the first roller 431 acts in a reverse direction to the first roller 431, the direction of the reverse frictional resistance is in a direction in which the first roller 431 abuts against the rotating rod 320 (the direction can be understood as the forward direction), because the first roller 431 abuts against the rotating rod 320, the first roller 431 cannot move any further under the reverse frictional resistance, and the frictional force between the first roller 431 and the rotating rod 320 is always present, that the first roller 431 restricts the rotating rod 320 from rotating in the forward direction.
If the rotating rod 320 rotates in the opposite direction, a frictional resistance is generated between the rotating rod 320 and the first roller 431 and the second roller 421, the frictional resistance between the rotating rod 320 and the second roller 432 acts against the second roller 432, the direction of the acting frictional resistance is towards the direction in which the second roller 432 abuts against the rotating rod 320 (the direction can be understood as the opposite direction), the second roller 432 cannot move any further under the acting frictional resistance because the second roller 432 abuts against the rotating rod 320, and the frictional force between the second roller 432 and the rotating rod 320 is always present, that is, the second roller 432 restricts the rotating rod 320 from rotating in the opposite direction.
The above is an explanation about the first locking member 410 and the second locking member 420 being simultaneously in the locking position and capable of restricting the rotation of the rotation lever in the forward direction and the reverse direction. The unlocked position will be explained below.
The first protrusion 411 can move close to the second protrusion 421 in the circumferential direction to drive the first roller 431 away from the rotating rod 320 in the radial direction, so that the first locking element 410 is switched to the unlocking position. Similarly, the second protrusion 421 can also move close to the first protrusion 411 in the circumferential direction to drive the second roller 432 to move away from the rotating rod 320 in the radial direction, so that the second locking element 420 is switched to the unlocking position.
With the first locking element 410 in the unlocked position and the second locking element 420 in the locked position, the first roller 431 does not radially abut the outer surface of the rotary lever 320 any longer, but the second roller 432 remains radially in abutment with the outer surface of the rotary lever 320. At this time, if the rotating rod 320 rotates in the forward direction, there is no more friction between the rotating rod 320 and the first roller 431, the friction exists between the rotating rod 320 and the second roller 432, the friction between the rotating rod 320 and the second roller 432 will react on the second roller 432, the reacted friction faces away from the direction in which the second roller 432 abuts against the rotating rod 320, the reacted friction will drive the second roller 432 to move close to the first roller 431 by overcoming the elastic member 440, and the second roller 432 abutting against the outer surface of the rotating rod 320 will not limit the rotating rod 320 to rotate in the forward direction. On the basis of the above, if the rotary lever 320 rotates in the reverse direction, the friction force between the rotary lever 320 and the second roller 432 is reacted to the second roller 432 in the direction in which the second roller 432 abuts against the rotary lever 320, and since the second roller 432 is already abutted against the rotary lever 320 and is no longer moving, the friction force between the second roller 432 and the rotary lever 320 is always present, so that the movement of the rotary lever 320 in the reverse direction is restricted.
With the first locking element 410 in the locked position and the second locking element 420 in the unlocked position, the second roller 432 no longer radially abuts the outer surface of the rotary lever 320, but the first roller 431 still radially remains in abutment with the outer surface of the rotary lever 320. At this time, if the rotating rod 320 rotates in the reverse direction, there is no friction between the rotating rod 320 and the second roller 432, the friction exists between the rotating rod 320 and the first roller 431, the friction between the rotating rod 320 and the first roller 431 will react to the first roller 431, the reacted friction faces away from the direction in which the first roller 431 abuts against the rotating rod 320, the reacted friction will drive the first roller 431 to approach the second roller 432 by overcoming the elastic force of the elastic member 440, and at this time, the first roller 431 abutting against the outer surface of the rotating rod 320 will not limit the rotating rod 320 to rotate in the reverse direction. On the basis of the above, if the rotary lever 320 rotates in the forward direction, the frictional force between the rotary lever 320 and the first roller 431 acts against the first roller 431 in the direction in which the first roller 431 abuts against the rotary lever 320, and since the first roller 431 already abuts against the rotary lever 320 and does not move any longer, the frictional force between the first roller 431 and the rotary lever 320 is always present, so that the movement of the rotary lever 320 rotating in the reverse direction is restricted.
With the first locking element 410 in the unlocked position and the second locking element 420 also in the unlocked position, the first roller 431 and the second roller 432 are driven by the two cams, respectively, to approach each other, eventually causing the first roller 431 and the second roller 432 to no longer abut the outer surface of the rotating rod 320 in the radial direction. At this time, the rotation of the rotary lever 320 in either the forward or reverse direction is not restricted by the two rollers.

When the first locking element 410 and the second locking element 420 are in the respective locking positions, the stoppers 430 are located at two ends of the transition section 312, and the first roller 431 and the second roller abut against the rotating rod 320 in the radial direction so as to limit the rotation of the rotating rod 320. The first roller 431 and/or the second roller 432 can be moved toward the middle region of the transition section 312 to be radially separated from the rotating rod 320, so that the rotating rod 320 can be rotated in both directions or in one direction along the circumferential direction.
It should be appreciated that the transition section 312 may not be disposed on the inner wall of the sleeve 310. The transition section 312 may also be disposed on the outer surface of the rotating rod 320, and in this case, the transition section 312 is different from the previous embodiment in that the radial dimension of the transition section 312 of the present embodiment gradually decreases from two ends to the middle to avoid two rolling bodies.
