[0033] Reference Figures 1 to 5 A quick conversion device includes a first connecting seat 10, a second connecting seat 20, and a locking assembly 30;

[0034] The first connecting seat 10 is provided with a locking part 11, and the first connecting seat 10 is used to connect to the shooting equipment;

[0035] The second connecting seat 20 is provided with a locking space 21, and the second connecting seat 20 is used to connect to the support assembly;

[0036] The locking assembly 30 is disposed on the second connecting seat 20 and has a locking position and an unlocking position that can be switched between each other;

[0037] The locking assembly 30 can abut against the locking part 11 extending into the locking space 21 when it is in the locked position to restrict the movement between the first connecting seat 10 and the second connecting seat 20; or the locking assembly 30 can separate from the locking part 11 when it is in the unlocked position to separate the first connecting seat 10 and the second connecting seat 20.

[0038] In this invention, the locking part 11 is located at the lower end of the first connecting seat 10, and the locking space 21 on the second connecting seat 20 faces upward. The locking part 11 is in the shape of an inverted frustum. In use, the first connecting seat 10 is connected to the shooting device, and the second connecting seat 20 is connected to the support assembly (the support assembly can be a tripod 91, a monopod 92, a slide rail 93, etc.). There can be multiple first connecting seats 10 and second connecting seats 20, which are connected to different shooting devices and support assemblies respectively. When it is necessary to switch the shooting device to another support assembly, such as switching the tripod 91 to the slide rail 93, it is only necessary to switch the locking assembly 30 to the unlocked position to separate the first connecting seat 10 and the second connecting seat 20. Then, the shooting device with the first connecting seat 10 installed is connected to the slide rail 93 with the second connecting seat 20 to complete the quick switch. The advantage of this invention is that the above structure can realize quick blind installation between the first connecting seat and the second connecting seat, improve the switching efficiency of the shooting device, meet the usage requirements, and has very good practicality.

[0039] Reference Figures 1-2 In some embodiments, the locking assembly 30 includes a first locking block 31, a second locking block 32, a first unlocking block 33, and a second unlocking block 34; the first locking block 31 and the second locking block 32 are arranged on the left and right sides of the locking part 11 respectively; the first unlocking block 33 is disposed on the front side of the locking part 11 and abuts against the first locking block 31 and the second locking block 32 respectively; the second unlocking block 34 is disposed on the rear side of the locking part 11 and abuts against the first locking block 31 and the second locking block 32 respectively; the first unlocking block 33 and the second unlocking block 34 can drive the first locking block 31 and the second locking block 32 from the unlocked position to the locked position or from the locked position to the unlocked position.

[0040] Specifically, the first locking block 31, the second locking block 32, the first unlocking block 33, and the second unlocking block 34 are evenly distributed around the periphery of the second connecting seat 20 and their lines form a cross structure. When the locking part 11 is inserted into the locking space 21, the locking part 11 pushes the first locking block 31 and the second locking block 32 outward until the locking part 11 passes the first locking block 31 and the second locking block 32. Under the action of the reset member, the first locking block 31 and the second locking block 32 are reset inward, causing the first locking block 31 and the second locking block 32 to return to their original positions. The first locking block 31 and the second locking block 32 are engaged with the upper end face of the locking part 11 to prevent the locking part 11 from disengaging from the locking space 21, thus enabling quick installation. When unlocking is required, the first unlocking block 33 and the second unlocking block 34 are operated to drive the first locking block 31 and the second locking block 32 from the locked position to the unlocked position. That is, the first locking block 31 and the second locking block 32 move outward until the first locking block 31 and the second locking block 32 are separated from the locking part 11. At this time, the locking part 11 can be disengaged from the locking space 21, thus enabling quick disassembly.

[0041] Reference Figures 1-2 In some embodiments, a first reset member 41 is provided on the first unlocking block 33, and a second reset member 42 is provided on the second unlocking block 34. The first reset member 41 abuts against the first locking block 31 and / or the second locking block 32 to drive the first locking block 31 and / or the second locking block 32 to reset. The second reset member 42 abuts against the first locking block 31 and / or the second locking block 32 to drive the first locking block 31 and / or the second locking block 32 to reset. Preferably, the first reset member 41 is a first torsion spring, which is sleeved on the first unlocking block 33 with one end abutting against the first locking block 31 and the other end abutting against the second locking block 32. The second reset member 42 is a second torsion spring, which is sleeved on the second unlocking block 34 with one end abutting against the first locking block 31 and the other end abutting against the second locking block 32.

[0042] Specifically, the first torsion spring is connected to the first unlocking block 33 via a first limiting bolt. One end of the first torsion spring abuts against the first abutting part of the first locking block 31 located at the front, and the other end of the first torsion spring abuts against the third abutting part 321 of the second locking block 32 located at the front. The second torsion spring is connected to the second unlocking block 34 via a second limiting bolt. One end of the second torsion spring abuts against the second abutting part 312 of the first locking block 31 located at the rear, and the other end of the second torsion spring abuts against the fourth abutting part 322 of the second locking block 32 located at the rear. Furthermore, the left side of the first unlocking block 33 abuts against the first locking block 31 through a beveled engagement, the right side of the first unlocking block 33 abuts against the second locking block 32 through a beveled engagement, and the left side of the second unlocking block 34 abuts against the first locking block 31 through a beveled engagement. The right side of the second unlocking block 34 abuts against the second locking block 32 through the engagement of the inclined surface. When the first unlocking block 33 and the second unlocking block 34 are pushed inward, the first locking block 31 and the second locking block 32 will be pushed outward. At the same time as the first locking block 31 and the second locking block 32 move outward, they will drive the first torsion spring and the second torsion spring to deform and store force. At this time, the locking assembly 40 enters the unlocked position. When the locking part 11 disengages from the locking space 21, the first unlocking block 33 and the second unlocking block 34 are released. The first torsion spring and the second torsion spring will deform and restore their shape and generate inward pressure, thereby driving the first locking block 31 and the second locking block 32 to move inward and driving the first unlocking block 33 and the second unlocking block 34 to move outward. At this time, the locking assembly 40 enters the locked position.

[0043] Reference Figures 1-2In some embodiments, the first locking block 31, the second locking block 32, the first unlocking block 33, and the second unlocking block 34 are connected to the second connecting seat 20 via a first limiting component 50 to limit the movement of the first locking block 31, the second locking block 32, the first unlocking block 33, and the second unlocking block 34 on the second connecting seat 20. Preferably, the first limiting component 50 includes a first limiting post 51, a second limiting post 52, a third limiting post 53, and a fourth limiting post 54. The second connecting seat 20 is provided with a first oblong hole 55, a second oblong hole, a third oblong hole 57, and a fourth oblong hole 58. The first limiting post 51 is mounted on the first locking block 31 and extends into the first oblong hole 55, and the second limiting post 52 is mounted on the second locking block 32 and extends into the first oblong hole 55. The third limiting post 53 is installed on the first unlocking block 33 and extends into the third waist-shaped hole 57, and the fourth limiting post 54 is installed on the second unlocking block 34 and extends into the fourth waist-shaped hole 58. Specifically, the second connecting seat 20 is provided with four movable slots 22 circumferentially, which are used to accommodate the first locking block 31, the second locking block 32, the first unlocking block 33 and the second unlocking block 34 respectively. The first waist-shaped hole 55, the second waist-shaped hole, the third waist-shaped hole 57 and the fourth waist-shaped hole 58 correspond one-to-one with the four movable slots 22. The first limiting post 51, the second limiting post 52, the third limiting post 53 and the fourth limiting post 54 are preferably set as nut screws, which can limit the movement of the locking block and the unlocking block and prevent them from detaching from the second connecting seat 20.

[0044] Reference Figures 1-2 In some embodiments, the first connecting seat 10 is connected to the second connecting seat 20 via a second limiting component 60 to restrict circumferential movement between the first connecting seat 10 and the second connecting seat 20. Preferably, the second limiting component 60 includes a plurality of limiting blocks 61 circumferentially disposed on the first connecting seat 10 and a plurality of limiting grooves 62 circumferentially disposed on the second connecting seat 20. The limiting blocks 61 can be inserted into the limiting grooves 62 when the first connecting seat 10 is installed on the second connecting seat 20. During installation, the first connecting seat 10 is rotated so that the limiting blocks 61 fall into the limiting grooves 62, and then the first connecting seat 10 is pressed down to lock the first connecting seat 10 and the second connecting seat 20. This can prevent circumferential relative movement between the first connecting seat 10 and the second connecting seat 20, and thus prevent unnecessary circumferential movement between the shooting device and the support component.

[0045] Reference Figures 1-2 In some embodiments, a wrench 70 is provided on the first connecting seat 10 or the second connecting seat 20.

[0046] Reference Figures 1-2 In some embodiments, a magnetic element 80 is provided on the first connecting seat 10 or the second connecting seat 20 for adsorbing the wrench 70.

Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
