Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more of the described features. In the description of the present utility model, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

In the description of the present utility model, it should be noted that, unless explicitly stated and limited otherwise, the terms "mounted," "disposed," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

Referring to fig. 1, the present utility model provides a horizontal-vertical photographing rotary ring 10, wherein the horizontal-vertical photographing rotary ring 10 is used for mounting a camera 20 on a photographic apparatus (not shown) such as a support frame, so as to expand the use functions of the camera 20 and assist the camera 20 in achieving various high-difficulty photographing operations. The extended use function of the horizontal and vertical photographing rotary ring 10 can be realized by installing various photographing extension accessories on the horizontal and vertical photographing rotary ring 10, and the photographing extension accessories can be a supporting arm, a photographing lamp, a microphone, a light supplementing lamp, a flash lamp and the like.

Referring to fig. 2, the horizontal and vertical photographing rotary ring 10 includes a support fixture 100 and a camera mount 200, the support fixture 100 being used to circumscribe a support frame, the camera mount 200 being used to mount the camera 20. When the camera mounting member 200 is assembled with the support fixing member 100, the camera mounting member 200 can deflect relative to the support fixing member 100, and the camera mounting member 200 can deflect at least 90 degrees in the circumferential direction and can be stably held and fixed relative to each other at a first position and a second position which are offset by 90 degrees in the circumferential direction. This can be understood as the switching of the camera 20 between landscape and portrait is achieved by the deflection of the camera mount 200 relative to the support mount 100.

The support fixing member 100 includes a support base 110 and a fixing ring 120, where the support base 110 is used to circumscribe a support frame. For example, fig. 3 and 4 illustrate that the support base 110 has a pair of plate structures 111 including guide rails, the plate structures 111 may be quick-release acard plates, and the plate structures 111 are used to establish quick-release connection with an acard quick-release groove of the support frame. Of course, the support base 110 may be externally connected to the support frame without the above-mentioned quick-assembly structure, for example, the support base 110 may be implemented by using other structures such as a threaded hole or a threaded shaft.

The fixing ring 120 is disposed above the supporting seat 110, the hollow area inside the fixing ring 120 is used for collecting light when the lens of the camera 20 shoots, and the adapting structure 121 for installing a photography lamp, a microphone, a light supplementing lamp, a flash lamp and the like can be disposed in the area outside the fixing ring 120, and the adapting structure 121 can be an adapting hole. It should be understood that the adaptor structure 121 is not necessarily required, and may be set according to actual use requirements.

The circumferential edge of the fixing ring 120 forms a ring groove 122 toward the center direction of the fixing ring 120, and the ring groove 122 may be understood as being formed by forming an annular groove in the inner sidewall of the fixing ring 120. Of course, the annular groove 122 may also be understood as being formed by surrounding two circumferentially extending protrusions on the inner side wall of the fixing ring 120. The annular groove 122 is formed with a notch 123 communicating with the annular groove 122 toward the axial direction of the fixed ring 120.

The camera mount 200 includes a mount 210 and a rotation ring 220, the mount 210 being for mounting the camera 20, and in particular, the mount 210 may be engaged with screw holes provided on the camera 20 by screws provided thereon. When the camera mount 200 is detached from the support fixture 100, the mount 210 can also be externally connected to a support frame, so that the rotating ring 220 is indirectly mounted to the support frame through the mount 210. Wherein, fig. 5 and 6 illustrate that the mounting base 210 has a pair of plate structures 211 including guide rails, the plate structures 211 may be an acard quick-mounting plate, and the plate structures 211 are used for establishing quick-release connection with an acard quick-mounting groove of the support frame. Of course, the support base 110 may be externally connected to the support frame without the above-mentioned quick-assembly structure, for example, the support base 110 may be implemented by using other structures such as a threaded hole or a threaded shaft.

The rotating ring 220 is disposed on the mounting base 210, and a boss 221 is formed on the periphery of the rotating ring 220 away from the center direction of the rotating ring 220, and the boss 221 can pass through the notch 123 to enter and exit the ring groove 122 to be detachably connected with the fixed ring 120. The boss 221 entering the annular groove 122 can drive the rotating ring 220 to rotate relative to the fixed ring 120 along the annular groove 122, so as to realize the switching of the shooting angles of the camera 20 mounted on the mounting base 210. The boss 221 can be held at least at a first position and a second position which are shifted by 90 degrees in the circumferential direction, so that the switching of the camera 20 between the horizontal shooting posture and the vertical shooting posture can be further realized. It should be noted that, when the boss 221 is aligned with the notch 123, the rotating ring 220 and the fixed ring 120 are axially detachable and separated, and when the boss 221 is dislocated with the notch 123, the rotating ring 220 and the fixed ring 120 are not axially detachable and separated, so as to ensure the stability of the rotating ring 220 and the fixed ring 120 after being mounted and connected. The rotating ring 220 is disposed coaxially with the fixed ring 120 when the rotating ring 220 is connected to the fixed ring 120.

In addition, the number of the bosses 221 may be plural and arranged at intervals in the circumferential direction, and the number of the notches 123 is equal to and corresponds to the number of the bosses 221. For example, fig. 3 and 4 illustrate that the number of the notches 123 is two, and for convenience of description and understanding, the two notches 123 are defined herein as a first notch 1231 and a second notch 1232, respectively. Fig. 5 and 6 illustrate that the number of the bosses 221 is two, and the two bosses 221 are defined herein as a first boss 2211 and a second boss 2212, respectively, for convenience of description and understanding. When the fixed ring 120 and the rotating ring 220 need to be assembled or disassembled, only the first boss 2211 needs to be aligned with the first notch 1231, and the second boss 2212 needs to be aligned with the second notch 1232, and at this time, only axial force needs to be applied to complete the disassembly and the buckling of the fixed ring 120 and the rotating ring 220.

For the horizontal and vertical photographing rotary ring 10 provided by the utility model, the rotary ring 220 is rotationally matched with the fixed ring 120 and can be kept at the first position and the second position which are staggered by 90 degrees in the circumferential direction, so that the camera 20 can deflect relative to the support frame to complete the adjustment of the camera 20 in the horizontal photographing posture and the vertical photographing posture, and different photographing use requirements of users are met. On this basis, because the boss 221 that rotatory ring 220 set up again can pass through the breach 123 that fixed ring 120 set up and get in and out the ring ditch 122 on the fixed ring 120 in order to be connected with fixed ring 120 can dismantle to when the user is not high to the demand that the gesture was taken in the horizontal and vertical time switched, can separate fixed ring 120 in rotatory ring 220 earlier, then with rotatory ring 220 pass through mount pad 210 and external on the support frame alone, richened the assembly mode of taking in the rotatory ring 10 of horizontal and vertical time like this, realize taking the rotatory ring 10 of horizontal and vertical time and reach simple structure and alleviate the purpose of device bulk weight on the basis of only providing one of horizontal or taking in the vertical time.

In an embodiment, the rotating ring 220 forms a first slot 222 and a second slot 223 which are offset by 90 degrees circumferentially away from the center of the rotating ring 220, the fixing ring 120 is provided with a mounting hole 124 extending to the inner side of the fixing ring 120, the supporting and fixing member 100 further comprises an elastic limiting device 130, and the elastic limiting device 130 can elastically protrude to the inner side of the fixing ring 120 and compressibly retract into the mounting hole 124. When the fixed ring 120 and the rotating ring 220 rotate relatively until the elastic limiting device 130 is opposite to the clamping groove, the elastic limiting device 130 elastically protrudes and can be clamped in the first clamping groove 222 to enable the boss 221 to be positioned at the first position, and also elastically protrudes and can be clamped in the second clamping groove 223 to enable the boss 221 to be positioned at the second position.

It should be noted that, referring to fig. 3 and 4, the mounting hole 124 is located at the notch 123, and the elastically protruding portion of the elastic limiting device 130 spans the annular groove 122 and the notch 123 in the axial direction of the fixing ring 120, so as to increase the axial width of the protruding portion. Referring to fig. 5 and 6, the first and second catching grooves 222 and 223 extend to the edge of the rotating ring 220, and the axial width of the first and second catching grooves 222 and 223 is greater than the axial width of the ring groove 122. So designed, the axial width of the protruding portion of the elastic limiting device 130 can be made wide enough, so that the protruding portion with the width can be contacted with the clamping groove as wide as possible, and the contact area of the protruding portion and the clamping groove is ensured, so that the stability of the first position and the second position relatively fixed is maintained. It is contemplated that if the mounting hole 124 is located at a position other than the notch 123 and at another position of the annular groove 122, the axial width of the portion of the elastic protruding portion of the elastic limiting device 130 tends to decrease (limited by the axial dimension of the annular groove 122), the width of the portion of the elastic protruding portion of the elastic limiting device 130 that can elastically protrude is smaller than the axial width of the annular groove 122, the contact area of the protruding portion when the protruding portion is engaged with the clamping groove is reduced, and stable damping is maintained.

In the embodiment where the mounting hole 124 is located at the notch 123, at least one of the first slot 222 and the second slot 223 is spaced from the boss 221 along the circumferential direction of the rotating ring 220, which may be understood as that at least one slot is not formed on the boss 221, and it is supposed that if all slots are formed on the boss 221, when all the bosses 221 are aligned with the notch 123, it is possible to simultaneously make the elastically protruding portion of the elastic limiting device 130 elastically protrude from the slot and be engaged in the slot. If this is true, the rotating ring 220 and the fixed ring 120 can be easily separated from each other in the axial direction, although the rotation limitation can be realized in the circumferential direction when switching to the first position and the second position.

Referring to fig. 2, in an embodiment, the elastic limiting device 130 includes a limiting member 131, a toggle member 132 and an elastic member 133, where the limiting member 131 includes a limiting section 1311, a blocking section 1312 and a fixing section 1313 connected in sequence, the limiting section 1311 can elastically protrude to the inner side of the fixing ring 120 and compressibly retract to the mounting hole 124, the toggle member 132 is connected to the blocking section 1312 and movably penetrates through the fixing ring 120, and the elastic member 133 is disposed between the fixing section 1313 and the supporting seat 110 and can accumulate and release elastic force. The toggle member 132 can overcome the elastic force of the elastic member 133 to drive the limiting segment 1311 to retract into the mounting hole 124. When the fixed ring 120 is rotated relative to the rotating ring 220 by operating the first position or the second position, since the rotation damping between the fixed ring 120 and the rotating ring 220 is large, a large external rotation force may be required to drive the fixed ring 120 and the rotating ring 220 to rotate relative to each other. In order to reduce the resistance of the fixed ring 120 and the rotating ring 220 to rotate, the toggle member 132 can be manually toggled during rotation to drive the limiting section 1311 to retract into the mounting hole 124, so that the resistance of the limiting section 1311 to the rotating ring 220 can be avoided.

In the above embodiment, when the rotation ring 220 is driven by an external force to rotate relative to the fixed ring 120, the limiting section 1311 can overcome the elastic force of the elastic member 133 and separate from the first clamping groove 222 and the second clamping groove 223. This can be achieved by setting the stop segment 1311 as an arcuate surface or setting the slot surface of the card slot as an arcuate surface.

When the rotating ring 220 is driven to rotate forward relative to the fixed ring 120 by an external force (in the direction of S arrow in the drawing), that is, when the fixed ring 120 rotates reversely relative to the rotating ring 220, the limiting section 1311 can be separated from the first clamping groove 222 and elastically clamped to the second clamping groove 223 when the limiting section is opposite to the second clamping groove 223 in the process of switching from the first position shown in fig. 7 and 8 to the second position shown in fig. 9 and 10. In the first position and the second position, the boss 221 is offset from the notch 123, so as to prevent the rotating ring 220 from being axially separated from the fixed ring 120.

In an embodiment, referring to fig. 5, the first card slot 222, the second card slot 223 and the boss 221 are sequentially arranged at intervals along the circumferential direction of the rotating ring 220, and the outer circumference of the rotating ring 220 is provided with a safety slot 225 between the second card slot 223 and the boss 221. When the rotating ring 220 continues to rotate in the forward direction from the second position shown in fig. 9 and 10, the limiting section 1311 is disengaged from the second clamping groove 223 and enters the safety groove 225, and the limiting section 1311 entering the safety groove 225 can limit the rotating ring 220 to rotate in the forward direction relative to the fixed ring 120. The safety groove 225 is configured to prevent the user from erroneously detaching the rotating ring 220 from the fixed ring 120 due to excessive rotation when the shooting gesture is switched, and the safety groove 225 is configured to enable the user to rotate the rotating ring 220 slightly forward to switch to the state shown in fig. 11 and 12 on the premise of pulling the pulling member 132, so that the boss 221 (the first boss 2211 defined as adjacent to the safety groove 225 in the drawing) is located in the notch 123 (the first notch 1231 is illustrated in the drawing), so as to detach the rotating ring 220 from the fixed ring 120.

In one embodiment, with continued reference to fig. 11 and 12, the boss 221 adjacent to the safety groove 225 is provided with a guide groove 2213, and the radial dimension of the guide groove 2213 decreases in the opposite circumferential direction (the opposite direction of the S arrow in the figure). The limiting section 1311 can move along the guiding groove 2213 to the end with the smallest radial dimension of the guiding groove 2213, when the limiting section 1311 moves to the end with the smallest radial dimension of the guiding groove 2213, the boss 221 is aligned with the notch 123, and the boss 221 can be separated from the ring groove 122 through the notch 123, so that the rotating ring 220 is separated from the fixed ring 120, and at this time, the resistance of the rotating ring 220 to be separated from the fixed ring 120 is reduced.

In an embodiment, referring to fig. 2, the fixing ring 120 is a closed ring, the curvature of any point on the inner surface of the fixing ring 120 is changed, the movable end 125 of the fixing ring 120 forms an extension section, the extension section is provided with a locking hole 1251, the supporting fixing member 100 further comprises a locking screw 140, and the locking screw 140 is inserted through the locking hole 1251 and is screwed to the fixed end 126 of the fixing ring 120. When the locking screw 140 is locked, the movable end 125 is closed towards the fixed end 126, and the boss 221 of the rotating ring 220 can be clamped in the ring groove 122, so that the relative position of the rotating ring 220 and the fixed ring 120 can be further stabilized.

In an embodiment, referring to fig. 2, the rotating ring 220 is provided with a first mounting hole 226, and the mounting seat 210 is provided with a second mounting hole 212, and the number of the first mounting holes 226 or the second mounting holes 212 is plural and the plural mounting holes are arranged in the longitudinal direction.
