Detailed implementation manners

[0031] In order to make the objectives and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be clear that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] Figure 1A perspective view of a camera device according to an embodiment of the present invention is shown. In this embodiment, the camera device is described by taking the universal bracket 200 as an example. The universal bracket 200 includes two arms 201 and a quick connection assembly 100 that can be connected to each arm 201. The two arms 201 are pivotally connected to each other through an angle locking member 203. Each arm 201 is connected to the quick connection assembly 100 through a universal joint 202. The quick connection assembly 100 connects the universal bracket 200 to other camera devices. Preferably, one of the two arms 201 is connected to a mounting base for a monitor, a camera, etc. through the quick connection assembly 100, and the other arm is connected to other camera devices (such as a tripod) through the quick connection assembly 100. In an alternative embodiment, both between the arm and the mounting base and between the arm and the quick connection assembly 100 are connected through the universal joint 202. The specific structures of the arm 201, the universal joint 202, the mounting base, and the angle locking member 203 are the same as those in the prior art and will not be described in detail here. The two arms 201 include a first arm and a second arm. For the convenience of description, the following takes the first arm as an example for illustration.

[0033] Referring also to Figure 2 and Figure 3 , the quick connection assembly 100 includes a connecting sleeve 1 and a connecting head 2. The connecting head 2 can be connected and fixed in the connecting sleeve 1. The connecting sleeve 1 includes a connecting portion 10 and a sleeve 11 perpendicular to the connecting portion 10. The sleeve 11 is generally in a hollow columnar shape. In this embodiment, the connecting portion 10 at least partially covers an axial end of the sleeve 11. The connecting sleeve 1 is connected to the universal joint 202 of the first arm through its connecting portion 10. In this embodiment, the connecting portion 10 is connected to the universal joint 202 through a first fixing member 204 of the universal joint 202. The connecting portion 10 is provided with a fixing post 101 corresponding to the first fixing member 204, and the first fixing member 204 can be fixed in the fixing post 101. The first fixing member 204 can pre-assemble the connecting sleeve 1 on a camera device (such as a universal bracket, a tripod, etc.), so the connecting sleeve 1 can be arranged as a pre-assembled part.

[0034] The connecting sleeve 1 further includes a first locking member 13 mounted on the sleeve 11 and at least one second locking member 14 provided on the connecting portion 10. The first locking member 13 prevents the axial movement of the connector head 2 relative to the connecting sleeve 1. At least one second locking member 14 prevents the rotation of the connector head 2 relative to the connecting sleeve 1. The connector head 2 is generally cylindrical and is received in the sleeve 11. In this embodiment, the connector head 2 includes a generally cylindrical body 21, an annular groove 22 provided along the circumferential direction of the body 21, and a connecting plate 23 provided at the axial end of the body 21. After the connector head 2 is installed in the connecting sleeve 1, the first locking member 13 partially enters the annular groove 22 to prevent the axial movement of the connector head 2 relative to the connecting sleeve 1; and at least one second locking member 14 cooperates with the connecting plate 23 to prevent the rotation of the connector head 2 relative to the connecting sleeve 1.

[0035] Specifically, the first locking member 13 is rotatable relative to the sleeve 11. After the connector head 2 is inserted into the connecting sleeve 1, the first locking member 13 can rotate relative to the sleeve 11 and can enter the annular groove 22 of the connector head 2 so as to automatically lock the connector head 2 in the connecting sleeve 1 in the axial direction of the connecting sleeve 1. The user can press the first locking member 13 to disengage the first locking member 13 from the annular groove 22, thereby releasing the axial lock of the connector head 2 in the connecting sleeve 1.

[0036] Refer also to Figures 3 to 4b . The first locking member 13 is rotatably mounted on the sleeve 11 of the connecting sleeve 1 through a first connecting member 138. In this embodiment, the first connecting member 138 is configured as a pin. A first elastic member 137 is sleeved on the first connecting member 138, and both ends of the first elastic member 137 respectively abut against the first locking member 13 and the sleeve 11, so that the first locking member 13 presses against the sleeve 11. Preferably, the first elastic member 137 is a torsion spring. In this embodiment, one side of the sleeve 11 where the first locking member 13 is installed is provided with a first convex portion 111 protruding radially outward. The first convex portion 111 thickens the wall thickness of the sleeve 11 at this position, thereby facilitating the positioning of the first locking member 13.

[0037] The first locking member 13 is provided with a tail portion 134 for the user to press and a head portion 133 pressing against the sleeve 11. The user can press the tail portion 134 to disengage the first locking member 13 from the annular groove 22 of the connector head 2. A plurality of mounting portions 135 extending towards the sleeve 11 are provided on the tail portion 134. In this embodiment, the plurality of mounting portions 135 includes two mounting portions 135. The center of each mounting portion 135 is provided with a through hole 136. The first connecting member 138 can pass through the through hole 136 to connect the first locking member 13 to the sleeve 11. The first elastic member 137 is arranged between the two mounting portions 135. Under the action of the first elastic member 137, the head portion 133 of the first locking member 13 presses into the sleeve 11.

[0038] The first locking member 13 further has a locking portion 130 extending from the head 133 towards the inside of the sleeve 11. In this embodiment, the locking portion 130 is located in the inner diameter direction of the sleeve 11 in the locked state. The locking portion 130 has a first locking surface 131 and a first inclined surface 132. The first locking surface 131 is arranged between the connecting portion 10 and the first inclined surface 132. The first locking surface 131 is along the inner diameter direction of the sleeve 11 and towards the connecting portion 10 of the connecting sleeve 1. The first locking surface 131 is perpendicular to the head 133. In this embodiment, the first locking surface 131 and the first inclined surface 132 are arranged opposite to each other in the axial direction of the sleeve 11. The first inclined surface 132 extends from the head 133 towards the first locking surface 131. The first locking surface 131 facilitates the insertion of the connector 2 into the connecting sleeve 1 without pressing the tail 134 of the first locking member 13. In this embodiment, the first locking surface 131 is provided as a stepped surface. Optionally, the first locking surface 131 may be flush with one end surface of the head 133 (adjacent to the first locking surface 131), and the first inclined surface 132 is inclined from the other end surface of the head 133 (opposite to the above-mentioned end surface) towards the first locking surface 131.

[0039] The locking portion 130 of the first locking member 13 can enter the annular groove 22 of the connector 2 and engage in the annular groove 22. As Figure 5 shown, the annular groove 22 has a second locking surface 221 and a second inclined surface 222. Referring to Figure 3 and Figure 5 simultaneously, in the locked state, the first locking surface 131 abuts against the second locking surface 221, and the first inclined surface 132 abuts against the second inclined surface 222. During the insertion of the connector 2 into the connecting sleeve 1, the connector 2 acts on the first inclined surface 132, causing the first locking member 13 to rotate around the first connecting member 138, thereby causing the locking portion 130 to withdraw from the inside of the sleeve 11 of the connecting sleeve 1. As the connector 2 is inserted into the connecting sleeve 1, when the annular groove 22 reaches the position of the locking portion 130, the locking portion 130 automatically enters the annular groove 22 under the action of the first elastic member 137 of the first locking member 13, realizing the locking of the connector 2 in the axial direction of the connecting sleeve 1.

[0040] The rotation of the connector 2 relative to the connecting sleeve 1 is locked by at least one second locking member 14. Specifically, at least one second locking member 14 is arranged on the connecting portion 10 of the connecting sleeve 1. Referring back to Figures 2 to 4b , at least one second locking member 14 protrudes towards the sleeve 11 from the connecting portion 10. In this embodiment, at least one second locking member 14 is a pin, which is fixed in the pin hole 102 on the connecting portion 10. Optionally, at least one second locking member is formed integrally with the connecting portion.

[0041] The body 21 of the connector 2 is provided with a connecting plate 23 towards the axial end of the connecting portion 10. In this embodiment, the connecting plate 23 is generally set as a sector, preferably a semi-circle, and its radius is not greater than the outer diameter of the body 21. In the locked state, the cooperation of at least one second locking member 14 and the connecting plate 23 prevents the rotation of the connector 2 relative to the connecting sleeve 1. In this embodiment, the connecting plate 23 is rotatably connected to the body 21. The center of the body 21 is set as a mounting hole 211. A connecting column 24 is vertically arranged in the mounting hole 211, and the connecting plate 23 is rotatably connected to the connecting column 24 through a connecting pin 234. Therefore, the connecting plate 23 can rotate around the connecting column 24.

[0042] The connecting column 24 is connected to a second fixing member 25 installed in the body 21. The second fixing member 25 includes an inner fixing member 251 fixed to the connecting column 24, an outer fixing member 252 arranged outside the inner fixing member 251, and a second elastic member 253 pressing against the outer fixing member 252. The outer fixing member 252 can move axially relative to the inner fixing member 251 along the axial direction of the inner fixing member 251. The inner fixing member 251 and the outer fixing member 252 are axially limited in the body 21 by the abutment of the steps between them. Therefore, the axial limitation of the connecting column 24 connected to the inner fixing member 251 in the body 21 is achieved. In addition, the connector 2 further has a flange 210 arranged at the end of the body 21 away from the connecting column 24 and extending radially outward along the body 21. After the connector 2 is installed on the connecting sleeve 1, the flange 210 abuts against the end of the sleeve 11 to achieve an aesthetic effect.

[0043] The connecting plate 23 can rotate around the axial direction of the body 21, thereby driving the connecting column 24 to also rotate relative to the body 21. Therefore, the inner fixing member 251 fixed to the connecting column 24 can also rotate relative to the body 21. When rotating the connecting plate 23 around the axial direction of the body 21, the inner fixing member 251 can be rotatably installed on a corresponding imaging device (such as an imaging bracket, a camera, and a video camera, etc.), so as to conveniently and labor-savingly connect the device to the connector 2.

[0044] Therefore, the connecting plate 23 can rotate both around the axial direction of the body 21 and around the radial direction of the body 21. After the connector 2 is connected to an imaging device (such as an imaging bracket, a camera, and a video camera, etc.), the rotation of the connector 2 around the axial direction of the body 21 is prevented.

[0045] After the connector 2 connected with the imaging device is inserted into the connecting sleeve 1, the rotation of the connector 2 relative to the connecting sleeve 1 is realized by the cooperation of at least one second locking member 14 and the connecting plate 23. In the locked state, the connecting plate 23 fits on the body 21. When the connecting plate 23 fits on the body 21, the connecting plate 23 has a stop surface 232 substantially parallel to the axial direction of the body 21 and two main surfaces 231 parallel to the radial direction of the body 21. In this embodiment, the connecting plate 23 is provided with at least one positioning hole 233 communicating the two main surfaces 231. The at least one second locking member 14 can be engaged in the at least one positioning hole 233, thereby locking the rotation of the connector 2 relative to the connecting sleeve 1. Preferably, the at least one second locking member 14 is a pin, which can be inserted into the at least one positioning hole 233.

[0046] In this embodiment, the at least one positioning hole 233 includes three positioning holes 233. The at least one second locking member 14 includes three second locking members 14. Referring simultaneously to Figure 6a and Figure 6b , in the top view of the quick-connect assembly 100, the three positioning holes 233 and the three second locking members 14 are arranged at equal intervals on a concentric circle concentric with the outer periphery of the connector 2. In this locked state of the quick-connect assembly 100, the stop surface 232 of the connecting plate 23 abuts against two second locking members 14, thereby locking the rotation of the connector 2 relative to the connecting sleeve 1. In this embodiment, the configuration of the three positioning holes 233 and the three second locking members 14 facilitates the user to insert the connector 2 into the connecting sleeve 1 without having to align the two precisely. Specifically, the rotation of the connector 2 relative to the connecting sleeve 1 can be locked in the following situations: the three second locking members 14 are respectively inserted into the three positioning holes 233 to lock the above rotation; two adjacent second locking members 14 are respectively inserted into two adjacent positioning holes 233 to lock the above rotation; one second locking member 14 is inserted into a corresponding positioning hole 233 to lock the above rotation; and the stop surface 232 abuts against two second locking members 14 to lock the above rotation. Optionally, the connecting plate 23 and the body 21 of the connector 2 can be integrally formed. The setting of the positioning holes on the connecting plate 23 can be the same as that in the above embodiment, and will not be described in detail here.

[0047] Referring simultaneously to Figure 7a and Figure 7b, perspective views of the quick-connect assembly 100 are respectively shown in its locked state and released state. The quick-connect assembly 100 includes a trigger 3 provided on the connecting sleeve 1. The trigger 3 is pivotable relative to the connecting sleeve 1. By changing the radial dimension of the connecting sleeve 1 through the trigger 3, the connector 2 is clamped in the connecting sleeve 1. In actual use, if only the trigger 3 is used to achieve the locked state and released state of the quick-connect assembly, when another imaging device (such as a camera, monitor, etc.) connected to the quick-connect assembly and facing downward is connected to an imaging device (such as a bracket 200), rotating the trigger 3 to release the connector 2 (connected to another imaging device) will cause the other imaging device to suddenly drop under its own gravity and be damaged. Therefore, the above-mentioned first locking member 13 provided on the connecting sleeve 1 of the quick-connect assembly 100 provided by the present invention is such that when the trigger 3 is opened, the connector 2 remains in the connecting sleeve 1 via the first locking member 13. In addition, since another imaging device has a relatively large weight and a relatively large dimension in the axial direction transverse to the quick-connect assembly, it results in that in actual use, the locking by only the trigger 3 cannot completely prevent the rotation of the connector 2 relative to the connecting sleeve 1. Therefore, the above-mentioned at least one second locking member 14 provided on the connector 2 of the quick-connect assembly 100 provided by the present invention further prevents the rotation of the connector 2 relative to the connecting sleeve 1.

[0048] In the locked state, the head 133 of the first locking member 13 is pressed into the sleeve 11 to lock the connector 2 in the connecting sleeve 1. To unlock the connector 2 from the connecting sleeve 1, open the trigger 3, then press the tail 134 of the first locking member 13 to move the head 133 out of the connector 2, and the unlocking of the connector 2 can be achieved. To lock the connector 2 in the connecting sleeve 1, insert the connector 2 into the connecting sleeve 1. The first locking member 13 rotates relative to the connecting sleeve 1 under the action of the connector 2, and then automatically engages in the annular groove 22 of the connector 2. At the same time, at least the second locking member 14 prevents the rotation of the connector 2 relative to the connecting sleeve 1, and then close the trigger 3, thereby locking the connector 2 in the connecting sleeve 1. In addition, the trigger 3 can also compensate for the gap caused by assembly tolerances to achieve a firm connection between the connector 2 and the connecting sleeve 1.

[0049] The trigger 3 is mounted on the sleeve 11 of the connecting sleeve 1. Also refer to Figure 4b, the sleeve 11 of the connecting sleeve 1 is partially open in its circumferential direction. The sleeve 11 has two second protrusion parts 112 extending outward from both ends of the partially open sleeve 11. The two second protrusion parts 112 extend outward in parallel. Each second protrusion part 112 is provided with a connecting hole 114 perpendicular to its extending direction. The second connecting member 34 passes through the two connecting holes 114 to connect the trigger 3 to the sleeve 11. In this embodiment, one end of the second connecting member 34 is fixed in the corresponding connecting hole 114 of a second protrusion part 112 by a nut 37, and the other end of the second connecting member 34 passes through the corresponding connecting hole 114 of the other second protrusion part 112 and is connected to the trigger 3. When the trigger 3 pivots relative to the sleeve 11, the second connecting member 34 can cooperate with the trigger 3 to reduce the distance between the two second protrusion parts 112, thereby reducing the inner diameter of the partially open sleeve 11 of the connecting sleeve 1 and clamping the connector head 2 engaged in the connecting sleeve 1 therein.

[0050] In this embodiment, one end of the second connecting member 34 can be connected to the nut 37 by a thread, and the other end is arranged as a connecting end 341 with a central opening. In other embodiments, the said one end of the second connecting member 34 can be connected and fixed in the corresponding connecting hole 114 of the corresponding second protrusion part 112 in any applicable manner.

[0051] The trigger 3 includes a handle 31 for the user to operate its pivoting and a biasing part 32 provided at a transverse end of the handle 31. The thickness of the biasing part 32 in the direction perpendicular to the transverse end is greater than the thickness of the handle 31 in this direction. In this embodiment, the biasing part 32 is arranged in an arc shape. The biasing part 32 is provided with an eccentric hole 33 arranged eccentrically in its vertical direction. The pivoting of the trigger 3 relative to the connecting sleeve 1 causes the connecting sleeve 1 to have a clamping state and a release state. When the trigger 3 pivots relative to the connecting sleeve 1 to clamp the connector head 2, the eccentric hole 33 of the trigger 3 is eccentrically arranged farther away from a second protrusion part 112 of the connecting sleeve 1. The third connecting member 35 is arranged in the eccentric hole 33, and the third connecting member 35 is connected to the second connecting member 34 to pivotally connect the trigger 3 to the connecting sleeve 1. Preferably, the third connecting member 35 passes through the connecting end 341 of the second connecting member 34. In this embodiment, the third connecting member 35 is a pivot shaft. Therefore, when the trigger 3 rotates from its release position to the clamping position, due to the arrangement of the eccentric hole 33, the distance between the eccentric hole 33 and the sleeve 11 and its adjacent second protrusion part 112 increases. The trigger 3 cooperates with the second connecting member 34 to reduce the distance between the two second protrusion parts 112, thereby causing the inner diameter of the sleeve 11 of the connecting sleeve 1 to decrease and clamping the connector head 2 in the connecting sleeve 1.

[0052] In this embodiment, a third elastic member 36 sleeved on the second connecting member 34 is further provided between the two second protruding portions 112. The two ends of the third elastic member 36 respectively abut against the corresponding second protruding portions 112, so that the trigger 3 can be stably located at the locked position.

[0053] At a corresponding position of the second protruding portion 112 adjacent to the biasing portion 32, a limiting groove 113 is provided. A pressing block 38 is arranged in the limiting groove 113, and the second connecting member 34 passes through the pressing block 38 and is connected to the trigger 3. A biasing prevention head 381 capable of engaging in the biasing portion 32 is provided on one side of the pressing block 38, so that the trigger 3 will not shake when in the clamping position, realizing reliable positioning of the trigger 3. In this embodiment, the pressing block 38 can also protect the biasing portion 32 and prevent wear of the biasing portion 32.

[0054] As Figure 8 shown, the universal bracket 200 provided with the above-mentioned quick connection component 100 according to the present invention can be connected to an existing imaging device 300 (such as an imaging bracket) through the quick connection component 100 to form an imaging equipment assembly 400 having the universal bracket 200 and the quick connection component 100. In addition, the universal bracket 200 is also suitable for being installed on cameras, video cameras, etc. It can be conceived that the quick connection component 100 provided by the present invention is suitable for connecting an imaging device (such as a camera, a monitor, a fill light, a microphone, etc.) to another imaging device (such as a tripod), rather than being limited only to the connection combinations related to the universal bracket.

[0055] The quick connection component 100 provided by the present invention has a simple structure, is simple and fast to install and disassemble, has a reliable locking effect, and improves the safety of connection.

[0056] In summary, the above are only the preferred embodiments of the present invention and are not used to limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made according to the content of the present invention should fall within the technical scope of the present invention.
