[0001] The invention relates to the technical field of photography auxiliary equipment, and in particular to a quick-release mount. Background Art

[0002] When using a camera on various devices, it is inseparable from the coordinated use of a quick release plate and a clamp. Most of the camera clamps in the prior art adopt a knob-pushing locking method. During the locking and unlocking process, the movable clamp is driven close to or away from the fixed clamp by manual rotation to achieve the locking or unlocking of the quick release plate. However, during the locking or unlocking process, the knob needs to be turned several times to complete the locking or unlocking of the quick release plate, which makes the use process cumbersome and inefficient. Summary of the invention

[0003] In view of this, an object of the present invention is to provide a quick release mount to solve the problem of complicated operation and low efficiency in locking or unlocking a quick release plate of a camera clamp in the prior art.

[0004] The present invention is achieved through the following technical solutions:

[0005] A quick-release seat, comprising a shell, a mounting groove for mounting a quick-release plate on the top of the shell, a locking member pivotally mounted in the mounting groove, when the quick-release plate is installed in the mounting groove, the locking member swings and switches to a clamping state under the pressure of the quick-release plate, and cooperates with the groove wall of the mounting groove to clamp the quick-release plate;

[0006] A locking member is rotatably connected to the interior of the housing, and an elastic member A is connected to the locking member. When the locking member is switched to the clamping state, the locking member swings and staggers with the locking member up and down. The locking member rotates counterclockwise under the force generated by the elastic member A and abuts against the locking member, switching the locking member to the locked state.

[0007] It also includes a button for pushing the locking member to rotate clockwise to switch the locking member from a locked state to an unlocked state.

[0008] Furthermore, an elastic member B is installed below the locking member. When the locking member is switched to an unlocked state, the locking member swings outward under the force generated by the elastic member B and extends to the movement path of the locking member. The locking member can rotate under the force generated by the elastic member A and resist against the side of the locking member, and the quick-release seat is in an unlocked standby state.

[0009] Furthermore, a rotation groove is provided on the groove wall of the installation groove, the locking member is installed in the rotation groove, the locking member comprises a mounting portion and a clamping portion integrally formed with the mounting portion, and an angle α is formed between the clamping portion and the installation portion;

[0010] The locking member further comprises a rotating shaft fixedly arranged outside the mounting portion and rotatably matched with the rotating groove, wherein the rotating shaft is close to the connection between the mounting portion and the clamping portion;

[0011] A triggering member is installed on the front top surface of the mounting portion, and a through hole is provided on the surface of the housing for the triggering member to extend into the mounting groove;

[0012] When the quick-release plate is installed in the installation slot, the quick-release plate presses the trigger member downward, and the installation portion drives the clamping portion to pivot and swing around the rotating shaft to clamp the quick-release plate.

[0013] Furthermore, the locking member includes a ring body rotatably connected to the housing, and a locking portion is integrally formed on the outer circumferential surface of the ring body. When the ring body rotates clockwise, the locking portion can be driven to move and separate from the locking member, switching to an unlocked state;

[0014] The outer circumferential surface of the ring body protrudes outward to form a support ear, and a receiving groove for installing the elastic member A is opened on the top inner wall of the shell. The elastic member A is installed between the support ear and the end wall of the receiving groove.

[0015] Furthermore, the bottom surface of the locking portion is an inclined surface, and one end surface of the locking member close to the inclined surface sinks to form a stop surface. When the locking member is in a locked state, the locking portion presses down the stop surface through the inclined surface to lock the locking member.

[0016] Furthermore, a mounting hole is provided through the side of the shell, and the button is installed in the mounting hole. The button includes a rod body and a head, and the head faces the support ear. When the button is pressed, the locking member is separated from the locking member under the push of the button and switched to an unlocked state.

[0017] Furthermore, a limiting block is provided at the opening of the mounting hole facing inward, and a notch is provided at one end of the rod body facing the limiting block, and the button can be pressed when the notch is aligned with the limiting block.

[0018] Furthermore, a side hole is radially opened on the rod body, an elastic member C is fixedly installed in the side hole, and a ball is fixedly installed on one end of the elastic member C facing the opening of the side hole;

[0019] The hole wall of the mounting hole deepens outward to form an arc-shaped groove with a diameter greater than the diameter of the mounting hole, and along the arc direction of the arc-shaped groove, two grooves are deepened outward at both ends of the arc-shaped groove to form two grooves, the diameter of the groove is the same as the diameter of the wave ball, and the depth of the groove is half of the diameter of the wave ball;

[0020] The button is rotated to cause the ball to slide along the arc groove and switch between the two grooves, thereby switching the alignment state of the notch and the limit block.

[0021] Furthermore, the outer surface of the rod body is provided with an indicator groove, the indicator groove extends along the length direction of the rod body and is connected to the side hole, and the side surface of the shell is provided with an open mark and a closed mark, and the two marks correspond to the positions of the two arc grooves respectively.

[0022] Furthermore, a block is mounted on the top inner wall of the shell, an elastic member D is sleeved outside the rod body, and the elastic member D is located between the head and the block.

[0023] The beneficial effects of the present invention are:

[0024] When the quick-release plate is installed in the installation slot, on the one hand, the quick-release plate presses down the locking member to swing and clamp the quick-release plate, and on the other hand, the locking member swings and separates from the locking portion up and down under the pressure of the quick-release plate, and then the locking member quickly rotates counterclockwise under the action of the deformation of the elastic member A, and the locking member is inserted between the locking member and the inner wall of the shell to lock the locking member, thereby quickly and automatically clamping the quick-release plate;

[0025] When unlocking is required, the button is manually pressed, and the locking piece rotates clockwise under the push of the button, causing the locking piece to separate from the locking piece, thereby releasing the locking state of the locking piece. At this time, the quick-release plate can be directly taken out. In summary, the quick-release seat of the present invention can be self-locking when the quick-release plate is installed in the installation slot, and it only needs to press the button to unlock. Compared with the locking device of the prior art, the quick-release plate of the present invention is faster and more convenient to lock or unlock, and the user experience is better.

[0037] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0038] In the description of the present application, the terms "upper", "lower", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0039] See also Figure 1 and Figure 3 The present invention provides a technical solution: a quick-release seat, comprising a cover-shaped shell 1 as a whole, a bottom plate 27 for closing the opening connected to the bottom opening of the shell 1 by screws, a mounting groove 11 for mounting a quick-release plate on the top of the shell 1, a rotating groove 12 is provided on the groove wall of the mounting groove 11, a locking member 2 is pivotally installed in the rotating groove 12, when the quick-release plate is installed in the mounting groove 11, the locking member 2 swings relative to the quick-release plate under the pressure of the quick-release plate, and cooperates with the groove wall of the mounting groove 11 to clamp the quick-release plate.

[0040] See also Figure 2 and Figure 3The locking member 2 is hook-shaped as a whole, and includes a mounting portion 21 and a clamping portion 22 integrally formed with the mounting portion 21. An angle α is formed between the clamping portion 22 and the mounting portion 21, and the angle range of the angle α is between 60 and 90 degrees, so that when the mounting portion 21 is in a horizontal state, the mounting portion 21 can swing slightly under the pressure of the quick-release plate to drive the locking member 2 to swing and clamp the quick-release plate.

[0041] See also Figure 2 and Figure 3 The locking member 2 also includes a rotating shaft 23 fixed outside the mounting portion 21 and rotatably matched with the rotating groove 12. The rotating shaft 23 is close to the connection between the mounting portion 21 and the clamping portion 22, so that the rotation center of the locking member 2 is positioned backward. When the mounting portion 21 moves downward under the action of an external force, the locking member 2 can swing relative to the quick-release plate to perform a clamping action through the cooperation of the rotating shaft 23 and the rotating groove 12, thereby clamping the quick-release plate. A pillar is integrally formed on the bottom plate 27 to support and assist the rotation of the rotating shaft 23.

[0042] See also Figure 1 and Figure 3 A trigger member 24 is installed on the front end top surface of the mounting portion 21, and a through hole 13 is opened on the surface of the housing 1 for the trigger member 24 to extend into the mounting groove 11. When the quick-release plate is installed in the mounting groove 11, the quick-release plate presses the trigger member 24 downward, and the locking member 2 swings around the rotating shaft 23 to approach the quick-release plate, and cooperates with the groove wall of the mounting groove 11 to clamp the quick-release plate.

[0043] See also Figure 2 The bottom surface of the front end of the mounting portion 21 and the top surface of the bottom plate 27 are respectively provided with spring mounting holes, in which elastic members B6 are installed. The elastic members B6 are used to generate an outward force to drive the locking member 2 to swing in the opposite direction to the clamping direction.

[0044] See also Figures 2 to 4 The inner wall at the top center of the housing 1 protrudes downward to form a truncated cone, and a locking member 3 is movably mounted outside the truncated cone. The locking member 3 can rotate circumferentially around the truncated cone. The locking member 3 includes a ring body 31 rotatably connected to the housing 1. The center line of the ring body 31 coincides with the center line of the truncated cone. A bearing can be installed between the ring body 31 and the truncated cone to make the rotation of the ring body 31 smoother.

[0045] The outer circumferential surface of the ring body 31 protrudes outward to form a support ear 33, and a receiving groove 14 is provided on the top inner wall of the housing 1. An elastic member A4 is installed in the receiving groove 14, and the two ends of the elastic member A4 are respectively in contact with the support ear 33 and the end wall of the receiving groove 14;

[0046] The outer circumferential surface of the ring body 31 is integrally formed with a locking portion 32, the bottom surface of the locking portion 32 is an inclined surface 34, and the end surface of the locking member 2 close to the inclined surface 34 is sunken to form a stop surface 25. When the locking member 2 is switched to the clamping state, the locking member 2 swings and staggers up and down with the locking member 3, and the locking member 3 rotates counterclockwise (by Figure 2 As a reference), the locking portion 32 locks the locking member 2 by squeezing the stop surface 25 through the inclined surface 34, switching the locking member 2 to a locked state, and when the ring body 31 rotates clockwise, the locking portion 32 can be driven to move and separate from the locking member 2, switching to an unlocked state;

[0047] The clamping and locking process of the quick-release plate: when the quick-release plate is installed, the quick-release plate squeezes the trigger member 24, and the locking member 2 swings around the rotating shaft 23 to clamp the quick-release plate, and at this time the stop surface 25 of the locking member 2 drops, and the locking member 2 is disengaged from the locking portion 32. The locking member 3 is pushed to rotate counterclockwise and reset under the action of the elastic member A4 being compressed and deformed back to its original state. The inclined surface 34 at the bottom of the locking portion 32 is inserted between the shell 1 and the stop surface 25, and cooperates with the stop surface 25 to press down the locking member 2, so that the locking member 2 locks the quick-release plate.

[0048] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 The side of the housing 1 is provided with a mounting hole 15, and a button 5 is installed in the mounting hole 15. The button 5 includes a rod 51 and a head 52, and the head 52 faces the ear 33. When the button 5 is pressed, the locking member 3 rotates clockwise under the push of the button 5 and separates from the locking member 2, switching to an unlocked state;

[0049] The opening of the mounting hole 15 facing inward is provided with a stop block 7, and the end of the rod body 51 facing the stop block 7 is provided with a notch 53, and when the notch 53 is aligned with the stop block 7, the button 5 can be pressed;

[0050] The outer surface of the rod body 51 is radially provided with a side hole 54, in which an elastic member C8 is fixedly installed, and a bead 9 is fixedly installed at one end of the elastic member C8 facing the opening of the side hole 54;

[0051] The hole wall of the mounting hole 15 deepens outward to form an arc groove 16 whose diameter is larger than that of the mounting hole 15. Along the arc direction of the arc groove 16, two grooves 17 are deepened outward at both ends of the arc groove 16. The diameter of the groove 17 is the same as the diameter of the wave ball 9. The depth of the groove 17 is half of the diameter of the wave ball 9. The wave ball 9 abuts against the groove wall of the arc groove 16 under the force generated by the deformation of the elastic member C8. When the wave ball 9 is in the arc groove 16, since the depth between the two grooves 17 is less than the depth outside the two grooves 17, and the wave ball 9 is under the force of the elastic member C8. Half of it extends into the groove 17, and the other half is located in the button 5. When the rotation angle of the button 5 is about to exceed the position of the groove 17, the elastic member C8 deforms to generate a large outward force to prevent the ball 9 from moving outward, and cooperates with the groove 17 to prevent the button 5 from continuing to rotate outward. Therefore, the button 5 can only rotate along the arc direction of the arc groove 16 within the angle range between the two grooves 17, and cannot continue to rotate outward to expand the angle. When the button 5 is rotated to cause the ball 9 to slide along the arc groove 16 and switch between the two grooves 17, the alignment state of the notch 53 and the limit block 7 also changes accordingly;

[0052] Secondly, when the button 5 is pressed, the ball 9 can move along the length direction of the groove 17, and the groove 17 can also play a guiding role.

[0053] See also Figure 1 , Figure 3 and Figure 5 The outer surface of the rod body 51 is provided with an indicator groove 10, the indicator groove 10 extends along the length direction of the rod body 51 and is connected to the side hole 54, and the side surface of the shell 1 is provided with an open mark 18 and a closed mark 19, and the two marks correspond to the positions of the two arc grooves 16 respectively;

[0054] The insertion rod is screwed in accordance with the marking on the side of the shell 1. When the indicating groove 10 points to the opening mark 18, the bead 9 extends into the corresponding groove 17 for limiting position under the action of the elastic member C8. At this time, the notch 53 is aligned with the limiting block 7. In this state, the button 5 can be pressed; when the indicating groove 10 points to the closing mark 19, the bead 9 extends into another groove 17 for limiting position under the action of the elastic member C8. At this time, the notch 53 is offset from the limiting block 7. In this state, the button 5 cannot be pressed to prevent the button 5 from being accidentally touched, causing the locking member 3 to rotate to unlock the locking member 2 and thereby release the quick-release plate.

[0055] The unlocking process of the quick-release plate: twist the button 5 to align the indicator groove 10 with the opening mark 18. At this time, the notch 53 is aligned with the limit block 7, and then the button 5 is pressed. The head 52 abuts against the ear 33 and pushes the ring body 31 to rotate clockwise through the ear 33. When the ring body 31 rotates clockwise, it drives the locking portion 32 to separate and stagger from the locking member 2. At this time, the locking member 2 swings under the action of the elastic member B6 to release the quick-release plate. When the locking member 2 swings, the mounting portion 21 flips and rises to move to the movement path of the locking portion 32. The locking portion 32 abuts against the side of the locking member 2 under the force generated by the compression deformation of the elastic member A4. The locking member 2 switches from the clamping state to the unlocking state, so that the quick-release plate can be unlocked by pressing the button 5. The final unlocking state is as shown in FIG. Figure 2 shown.

[0056] See also Figure 2 and Figure 3 A card block 20 is mounted on the top inner wall of the shell 1, and an elastic member D26 is mounted on the rod body 51. The elastic member D26 is located between the head 52 and the card block 20. The elastic member D26 is used to generate a smaller force when the locking member 3 is switched from an unlocked state to a locked state, so that the head 52 abuts against the ear 33, thereby ensuring the stability of the button 5 during use and avoiding shaking. The elastic members in this application document are all springs.

[0057] Finally, it should be noted that the above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention are within the scope of protection required by the present invention.
