Description

Technical Field

[0001] This application relates to the field of camera shooting equipment technology, and more specifically, to a camera quick-release device. Background Technology

[0002] A quick-release plate is a fixing mechanism used to connect cameras and photographic equipment such as tripods. It allows for quick mounting and dismounting of cameras from tripods and other photographic equipment, hence the name quick-release plate. Quick-release plates are a very important accessory for cameras.

[0003] Chinese patent CN218845501U discloses a camera quick-release device, including a mounting plate and a locking component for fixing the camera to the mounting plate. It also includes a locking assembly for connecting the camera shoulder strap and a limiting plate disposed on the mounting plate. The locking assembly includes an interlocking sleeve that cooperates with the limiting plate to achieve vertical limiting. The interlocking sleeve is provided with an interlocking limiting post. The interlocking limiting post has a first position that interlocks to limit the interlocking sleeve to a horizontal position and a second position that unlocks to allow the interlocking sleeve to move freely horizontally relative to the limiting plate. In actual use, the interlocking limiting post limits the interlocking sleeve, enabling quick installation and removal of the camera.

[0004] However, the aforementioned technologies have the following drawbacks: since most traditional quick-release plates are square, they can only be quickly inserted to achieve quick release when the angles are 90°. In actual use, because the installation angle is fixed, it is difficult to ensure that the camera lens can face the shooting direction after the camera is installed, thus limiting the camera's functionality. Summary of the Invention

The driving element is used to drive the connecting plate to move.

[0011] Optionally, the driving component is configured as a driving rod, and a through hole communicating with the second mounting groove is provided on the side wall of the base. The driving rod is slidably inserted into the through hole, one end of the driving rod is connected to the connecting plate, and the other end extends out of the through hole.

[0012] Optionally, the connecting plate has a positioning hole, and a positioning platform is fixedly installed on the bottom wall of the second mounting groove. The positioning platform is located in the positioning hole. The connecting plate has a threaded hole that is threadedly connected to the drive rod. The threaded hole is connected to the positioning hole. A limiting component is provided on the drive rod. The limiting component is used to limit the position of the drive rod on the base.

[0013] Optionally, the limiting component is configured as a limiting knob, which is located at the end of the drive rod away from the connecting plate.

[0014] Optionally, a threaded hole is provided on the inner wall of the positioning hole near the first positioning block, and a guide pin is threaded into the threaded hole. A guide hole is provided on the positioning platform, and the guide pin slides through the guide hole.

[0015] Optionally, the elastic element is configured as a compression spring, the connecting plate is provided with a receiving groove, the compression spring is disposed in the receiving groove, one end of the compression spring is fixedly connected to the connecting plate, and the other end is fixedly connected to the inner wall of the second mounting groove.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] In actual use, when the camera needs to be installed, it is first installed onto a tripod or other photographic equipment through the connecting slot or screw holes at the bottom of the base. Then, the camera is installed onto the quick-release plate through the connector. The quick-release plate and the positioning wheel then move toward the first mounting groove. After the positioning wheel enters the first mounting groove, the first inclined surface at the bottom of the positioning wheel slides and abuts against the second inclined surface of the first positioning block, causing the connecting plate to move. The connecting plate, through the connecting block, then causes the first positioning block to move, so that the bottom of the first positioning block abuts against the top of the positioning wheel, thereby positioning the vertical position of the positioning wheel in the first mounting groove. At this time, the positioning pin is inserted into the positioning groove, which limits the horizontal deflection position of the positioning wheel in the first mounting groove, preventing the positioning wheel from deflecting randomly in the first mounting groove during shooting.

[0018] After the camera is installed, if there is a certain deviation in the shooting direction of the camera, you can press the drive rod to drive the connecting plate to move, which in turn drives the positioning pin to move away from the positioning wheel, so that the positioning pin is disengaged from the positioning groove. This allows you to adjust the deflection angle of the positioning wheel (camera) and make the camera face the desired direction, making shooting more convenient.

[0019] After the camera is installed, the positioning pin is engaged in the positioning groove under the action of the elastic element. At this time, the user drives the limiting knob to rotate in the third mounting groove. As the limiting knob rotates, it deflects on the limiting protrusion with a ramp, and finally the limiting knob is engaged in the limiting slot under the action of the spring, thus fixing the rotation angle of the limiting knob. At this time, the limiting knob cannot be driven to move towards the base in the third mounting groove, and therefore the drive rod cannot be driven to move in the base, and the connecting plate cannot be driven to move. That is, the positioning pin cannot be disengaged from the positioning groove, and the first positioning block cannot be disengaged from the top of the positioning wheel. Through the above structure, it is possible to effectively prevent the positioning pin from disengaging from the positioning groove due to vibration or accidental human contact during shooting, and to prevent the first positioning block from disengaging from the positioning wheel, thus effectively ensuring the reliability of the connection between the camera and the base during shooting.

[0020] When the camera needs to be disassembled, the user moves the limit knob away from the third mounting slot, causing the limit knob to disengage from the limit slot. Then, the user rotates the limit knob, and as the limit knob deflects within the third mounting slot, it disengages from the limit boss. The user can then press the limit knob and the drive rod to move the connecting plate, the first positioning block, and the positioning post, causing the positioning post to disengage from the positioning slot and the first positioning block to disengage from the positioning wheel. At this point, the user can quickly disassemble the camera and the quick-release plate. The operation is simple and convenient, and it has good practicality. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0034] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0035] Example

[0036] This application discloses a camera quick-mount device.

[0037] Reference Figure 1 , 2 A camera quick-release device includes a base 1, a quick-release plate 11 on the base 1, a connector 12 for connecting a camera on the quick-release plate 11, a positioning wheel 13 on one end of the quick-release plate 11 near the base 1, a first mounting groove 2 on the base 1 to accommodate the positioning wheel 13, a first positioning block 14 slidably disposed in the first mounting groove 2, the bottom of the first positioning block 14 abutting against the top of the positioning wheel 13 to limit the vertical position of the positioning wheel 13 in the first mounting groove 2, and a positioning element 15 on the first positioning block 14 to limit the horizontal deflection position of the positioning wheel 13 on the first positioning block 14.

[0038] As one embodiment of this application, refer to Figure 1 The connector 12 is configured as a connecting bolt for connecting to the bottom of the camera, so that the camera and the quick-release plate 11 form a whole, so as to facilitate quick installation and removal of the camera.

[0039] Reference Figure 2 , 3 A limiting block 3 is fixedly installed on the top of the positioning wheel 13, and a notch 16 is provided at the bottom of the quick-release plate 11 for the limiting block 3 to be engaged. The overall structure of the limiting block 3 is designed as a dovetail shape. By setting the limiting block 3, the position of the positioning wheel 13 on the base 1 can be further limited, which further improves the overall reliability of the device in actual use.

[0040] Reference Figure 2 , 3 The bottom of the positioning wheel 13 is provided with a first inclined surface 31, and the first positioning block 14 is provided with a matching second inclined surface 32. When the positioning wheel 13 and the quick-release plate 11 are installed, the first inclined surface 31 and the second inclined surface 32 slide and abut against each other, thereby driving the first positioning block 14 and the connecting plate 51 to move horizontally within the base 1, which allows the user to complete the installation of the quick-release plate 11 and the positioning wheel 13 more conveniently and quickly.

[0041] Reference Figure 1 , 2 The top edge of the base 1 is designed with an arc surface, and the edge of the quick-release plate 11 is also designed with an arc surface. In actual use, when the quick-release plate 11 is inserted into the base 1, it is smoother and more fluid. The two fit together more tightly in actual use, which effectively improves the user's experience.

[0042] Reference Figure 2 , 3 As one embodiment of this application, the positioning member 15 is configured as a positioning post, which is set on the first positioning block 14. The peripheral wall of the positioning wheel 13 is provided with a plurality of positioning grooves 17 for the positioning post to be inserted into. The base 1 is provided with a driving member 4, which is used to drive the first positioning block 14 to move in the first mounting groove 2.

[0043] Reference Figure 2 , 3 The base 1 has a second mounting groove 5 at its bottom, and a connecting plate 51 is slidably disposed in the second mounting groove 5. The base 1 is provided with a sealing plate 8 for closing the second mounting groove 5. The bottom wall of the first mounting groove 2 has a through hole 21 that communicates with the second mounting groove 5. A connecting block 22 is disposed in the through hole 21. One end of the connecting block 22 is connected to the connecting plate 51, and the other end is connected to the first positioning block 14. The base 1 is provided with an elastic element 52, which is used to drive the connecting plate 51 to move so that the positioning post moves toward the positioning groove 17. The driving element 4 is used to drive the connecting plate 51 to move.

[0044] As one embodiment of this application, refer to Figure 5 , 6The driving component 4 is configured as a driving rod. A through hole 53 communicating with the second mounting groove 5 is provided on the side wall of the base 1. The driving rod slides through the through hole 53. One end of the driving rod is connected to the connecting plate 51, and the other end extends out of the through hole 53.

[0045] Reference Figure 5 , 6 The connecting plate 51 has a positioning hole 54. The bottom wall of the second mounting groove 5 is fixedly provided with a positioning platform 55, which is located in the positioning hole 54. The connecting plate 51 has a threaded hole that is threaded to the drive rod. The threaded hole is connected to the positioning hole 54. The end of the drive rod is used to abut against the side wall of the positioning platform 55. The drive rod is provided with a limiting member 6, which is used to limit the position of the drive rod on the base 1.

[0046] Among them, reference Figure 4 , 5 The positioning wheel 13 includes a thicker outer ring and a thinner inner ring. The end of the first positioning block 14 away from the connecting block 22 is set as an inclined surface, which is used to abut against the bottom of the outer ring. The top of the connecting plate 51 is fixedly provided with a second positioning block 18, and the bottom of the second positioning block 18 is used to abut against the top of the inner ring to further limit the position of the positioning wheel 13 in the first mounting groove 2.

[0047] Reference Figure 3 , 5 The height of the first positioning block 14 is higher than that of the second positioning block 18. When the position of the positioning wheel 13 in the first mounting groove 2 is limited, the bottom of the first positioning block 14 abuts against the top of the outer ring of the positioning wheel 13, and the bottom of the second positioning block 18 abuts against the top of the inner ring of the positioning wheel 13. This can effectively limit the position of the positioning wheel 13 in the vertical direction. The first positioning block 14 and the second positioning block 18 work together to position the positioning wheel 13, which is safer and more reliable.

[0048] Additionally, refer to Figure 3 , 4 The connecting plate 51 is provided with a first mounting block 191 and a second mounting block 192. The first mounting block 191 is located below the first positioning block 14. The top of the positioning post is fixedly connected to the bottom of the first positioning block 14, and the other end is connected to the first mounting block 191. The second mounting block 192 is located below the second positioning block 18.

[0049] Reference Figure 4 The inner bottom wall of the inner ring of the positioning wheel 13 is set as an inclined surface, and the top of the second mounting block 192 is also inclined, and the inclination angle of the second mounting block 192 is adapted to the inclination angle of the inner bottom wall of the inner ring of the positioning wheel 13.

[0050] In actual use, the first mounting block 191 abuts against the bottom of the outer ring of the positioning wheel 13, and the second mounting block 192 abuts against the bottom of the inner ring of the positioning wheel 13, as shown in the reference. Figure 3 , 4 The top of the first mounting block 191 and the top of the second mounting block 192 are both set as slopes. The slopes clamp the positioning wheel 13 in the first mounting groove 2, making the connection between the quick-release plate and the base 1 more secure and effectively improving the user experience of the camera.

[0051] Reference Figure 5 , 6 In one embodiment of this application, the elastic element 52 is configured as a compression spring, and the connecting plate 51 is provided with a receiving groove 56. The compression spring is disposed in the receiving groove 56, one end of the compression spring is fixedly connected to the connecting plate 51, and the other end is fixedly connected to the inner wall of the second mounting groove 5. There are two compression springs and two receiving grooves 56, which are respectively disposed on both sides of the connecting plate 51, and each receiving groove 56 is provided with a compression spring.

[0052] Reference Figure 7 , 8 9. The limiting component 6 is set as a limiting knob. The limiting knob is set at the end of the drive rod away from the connecting plate 51. The side wall of the base 1 is provided with a third mounting groove 61 for accommodating the limiting knob. The through hole 53 is opened in the bottom wall of the third mounting groove 61. The third mounting groove 61 is provided with a limiting boss 62 with a slope. The limiting boss 62 is provided with a limiting slot 63 for the limiting knob to be inserted. The limiting knob is slidably connected to the drive rod. A spring 64 is connected between the limiting knob and the drive rod. One end of the spring 64 is fixedly connected to the drive rod, and the other end is fixedly connected to the limiting knob.

[0053] Among them, reference Figure 7 , 8 The drive rod and the connecting plate 51 are connected by bolts. In actual use, the drive rod and the connecting plate 51 are locked together and there is no relative rotation. By driving the drive rod to move along the axis of the drive rod, the connecting plate 51 can be moved in the base 1. With the movement of the connecting plate 51, the first positioning block 14, the second positioning block 18 and the positioning column can be moved.

[0054] Reference Figure 7 The drive rod includes a threaded section 41 that is threadedly connected to the connecting plate 51, a sliding section 42 that is slidably disposed in the through hole 53, a limiting section 43 for abutting and limiting, and a connecting section 44. The connecting section 44 has a threaded hole at one end away from the connecting plate 51, and a connecting bolt is threadedly connected in the threaded hole.

[0055] Reference Figure 7, 9 The limiting knob has an inclined abutment surface 65 on the side near the connecting plate 51. An installation hole 66 is provided inside the limiting knob. The limiting section 43 and connecting section 44 of the drive rod, as well as the connecting bolt, are slidably disposed within the installation hole 66. The diameter of the installation hole 66 matches the diameter of the limiting section 43 and is slightly larger than the diameter of the connecting section 44. A limiting ring 67 is fixedly disposed within the installation hole 66. The inner diameter of the limiting ring 67 matches the connecting section 44, and the connecting section 44 slidably passes through the limiting ring 67. The diameter of the nut end of the connecting bolt matches the diameter of the installation hole 66. A spring 64 is disposed between the nut end of the connecting bolt and the limiting ring 67. One end of the spring 64 is fixedly connected to the nut, and the other end is fixedly connected to the limiting ring 67. An abutment platform 68 is provided inside the installation hole 66, which abuts against the side of the nut end near the connecting plate 51.

[0056] Reference Figure 8 , 9 When the limit knob is in the vertical position, the side wall of the limit knob near the connecting plate 51 is located in the limit slot 63 and abuts against the bottom wall of the limit slot 63. The side wall of the limit knob abuts against the side wall of the limit slot 63. In this state, the limit knob cannot rotate in the third mounting slot 61, nor can it move towards the base 1 along the axis of the drive rod, that is, it cannot drive the drive rod and the connecting plate 51 to move in the base 1.

[0057] When the limit knob is in the horizontal position, the limit knob tends to move toward the connecting plate 51 under the action of the spring 64. At this time, the side of the limit ring 67 close to the connecting plate 51 abuts against the side of the drive rod limit section 43 away from the connecting plate 51. Pressing the limit knob at this time will drive the connecting rod to move in the base 1, thereby driving the connecting plate 51 and the positioning column to move.

[0058] Meanwhile, when the limit knob is in the horizontal position, the position of the inclined abutment surface 65 on the limit knob matches the inclined surface position of the limit boss 62. At this time, by directly rotating the limit knob, the limit knob can be rotated and raised along the limit boss 62 with the slope design, without the user having to pull the limit knob again, which further simplifies the operation and has good practicality.

[0059] Reference Figure 4 , 5 A threaded hole is provided on the inner wall of the positioning hole 54 near the first positioning block 14, and a guide pin 7 is threaded into the threaded hole. A guide hole 71 is provided on the positioning table 55, and the guide pin 7 slides through the guide hole 71. By setting the guide pin 7, in actual use, it can effectively ensure that the overall movement of the device is smoother, more stable and more robust, and has good practicality.

[0060] The implementation principle of a camera quick-mount device according to an embodiment of this application is as follows:

[0061] In actual use, when the camera needs to be installed, it is first installed onto a tripod or other photographic equipment through the connecting slot at the bottom of the base or the screw holes at the bottom of the base 1. Then, the camera is installed onto the quick-release plate 11 through the connector 12. Subsequently, the quick-release plate 11 and the positioning wheel 13 move toward the first mounting groove 2. After the positioning wheel 13 enters the first mounting groove 2, the first inclined surface 31 of the positioning wheel 13 slides and abuts against the second inclined surface 32 of the first positioning block 14, causing the connecting plate 51 to move. 1. The connecting block 22 drives the first positioning block 14 and the second positioning block 18 to move, so that the bottom of the first positioning block 14 abuts against the top of the outer ring of the positioning wheel 13, and the second positioning block 18 abuts against the top of the inner ring of the positioning wheel 13, thereby positioning the positioning wheel 13 in the vertical position in the first mounting groove 2. At this time, the positioning pin is inserted into the positioning groove 17, which can limit the horizontal deflection position of the positioning wheel 13 in the first mounting groove 2, and prevent the positioning wheel 13 from deflecting in the first mounting groove 2 during the shooting process.

[0062] After the camera is installed, if there is a certain deviation in the shooting direction of the camera, you can press the drive rod to drive the connecting plate 51 to move, which in turn drives the positioning column to move away from the positioning wheel 13, so that the positioning column is disengaged from the positioning groove 17. This allows you to adjust the deflection angle of the positioning wheel 13 and make the camera face the desired shooting direction, making shooting more convenient.

[0063] After the camera is installed, the positioning pin is engaged in the positioning groove 17 under the action of the elastic element 52. At this time, the user drives the limiting knob to rotate in the third mounting groove 61. As the limiting knob rotates, it deflects on the limiting boss 62 with a slope, and finally the limiting knob is engaged in the limiting slot 63 under the action of the spring 64, thus fixing the rotation angle of the limiting knob. At this time, the limiting knob cannot be driven to move towards the base 1 in the third mounting groove 61, and thus the drive rod cannot be driven to move in the base 1, and the connecting plate 51 cannot be driven to move. That is, the positioning pin cannot be disengaged from the positioning groove 17, and the first positioning block 14 and the second positioning block 18 cannot be disengaged from the positioning wheel 13. Through the above structure, the positioning pin can be effectively prevented from disengaging from the positioning groove 17 due to vibration or accidental human contact during shooting, and the connection between the quick-release plate and the base can be reliably and safely maintained during the shooting process.

[0064] When the camera needs to be disassembled, the user moves the limiting knob away from the third mounting slot 61, causing the limiting knob to disengage from the limiting slot 63. Then, the user rotates the limiting knob. As the limiting knob deflects within the third mounting slot 61, once the limiting knob disengages from the limiting boss 62, the user can press the limiting knob and the drive rod to move the connecting plate 51, the first positioning block 14, and the positioning post. This causes the positioning post to disengage from the positioning slot 17, and the first positioning block 14, the second positioning block 18, and the positioning wheel 13 to disengage. At this point, the user can quickly disassemble the camera and the quick-release plate 11. The operation is simple and convenient, and it has good practicality.

[0065] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
