Description

Technical Field

[0001] The invention relates to the technical field of auxiliary photographic equipment, and in particular to a quick locking device and a photographic kit. Background Art

[0002] The camera clamp is the most important and most commonly used device in photographic equipment. When the camera is installed on the bracket for use, it is basically inseparable from the clamping of the clamp. Most of the existing camera clamps are knob-pushed locking. When locking, the movable clamp is driven to move to open the dovetail groove by turning the knob, and then the knob is turned in the opposite direction to drive the movable clamp to reset and cooperate with the fixed clamp to lock the camera quick release plate. This locking method requires repeated turning of the knob, which is cumbersome to operate, and the movable clamp moves slowly, and the locking and unlocking are not fast enough, and the efficiency is low. Summary of the invention

[0003] In view of this, the purpose of the present invention is to provide a quick locking device to solve the technical problems in the prior art that the knob-pushed camera clamp has to be repeatedly turned when locking, which is cumbersome, the movable clamp moves slowly, the locking and unlocking are not fast enough, and the efficiency is low.

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

[0005] A quick locking device, comprising a base and a shell fixed on the base, the top of the shell having a fixed chuck, a movable chuck inserted on a side of the shell opposite to the fixed chuck, a driving body connected to a side of the movable chuck facing the fixed chuck, and a triggering member for moving the driving body to drive the movable chuck away from or close to the fixed chuck for clamping installed on the base;

[0006] The trigger member is provided with a locking head. When the movable clamp moves close to the fixed clamp under the action of the trigger member, the trigger member quickly inserts the locking head into the driving body and abuts against it to lock it.

[0007] Furthermore, a clutch positioning column is integrally formed on the trigger member, and an inclined slot A and an inclined slot B connected to the inclined slot A are provided on the driving body, and the radius of the curve formed by connecting the center points of the inlet end of the inclined slot A and the terminal end of the inclined slot B along the direction of the slot body gradually decreases;

[0008] The inclined slot A is located on the movement track of the clutch positioning column. When the clutch positioning column enters the inclined slot B from the inclined slot A under the action of the trigger member, it pushes the driving body to move outward.

[0009] Furthermore, a protrusion A and a protrusion B are integrally formed at one end of the driving body away from the inclined groove A, and a locking groove for plugging and cooperating with the locking head is formed between the protrusion A and the protrusion B.

[0010] Furthermore, a mounting column is fixedly connected to an inward side of the base, a support ear is fixedly provided on the outer circumferential surface of the trigger member, and a tension spring is installed between the mounting column and the support ear.

[0011] Furthermore, a limiting mechanism is installed on the movable chuck, and a limiting hole is provided on the shell. When the movable chuck moves so that the limiting mechanism is aligned with the limiting hole, the limiting mechanism extends into the limiting hole to limit the movement of the movable chuck.

[0012] Furthermore, a sliding groove is provided on the outer circumferential surface of the shell and penetrates inside and outside, and a wrench is installed in the sliding groove. One end of the wrench is located outside the shell, and the other end extends into the shell and is fixedly connected to the trigger member.

[0013] A photography kit includes a planar thrust platform, wherein the planar thrust platform includes the quick locking device as described above, and the planar thrust platform is threadedly connected to the bottom of the base.

[0014] A photography kit comprises a camera conversion clamp seat, wherein the camera conversion clamp seat comprises the quick locking device as described above.

[0015] A photographic kit comprises a quick-installation plug-in plate, wherein the quick-installation plug-in plate comprises the quick locking device as described above.

[0016] The beneficial effects of the present invention are:

[0017] 1. When the trigger rotates counterclockwise, the driving body can be moved to drive the movable clamp away from the fixed clamp, and the clamp seat can be unlocked quickly. Then, the camera quick-release plate can be installed in the dovetail groove formed by the two clamps. After the installation is completed, the trigger is moved clockwise to reset. When the trigger rotates, the driving body is moved to drive the movable clamp to quickly reset and approach the fixed clamp to clamp the camera quick-release plate. The locking head is inserted into the driving body and locked against the driving body, thereby realizing fast and stable locking of the camera quick-release plate.

[0018] Compared with the prior art in which a knob is used to push the clamp to move for unlocking and clamping, the present invention only requires turning the trigger member to rotate to achieve quick installation and locking of the camera quick release plate, which is more convenient to operate and improves work efficiency and user experience.

[0019] 2. By setting the limit mechanism, the movable clamp can be limited to move and reset when the movable clamp moves away from the fixed clamp to reach the maximum stroke. When the camera quick-release plate is installed in the dovetail groove formed by the two clamps, the limit of the limit mechanism can be released by pressing downward. At this time, the trigger member is pulled and quickly rotated and reset under the force generated by the deformation of the tension spring back to its original state, thereby driving the movable clamp to cooperate with the fixed clamp to clamp the camera quick-release plate, and at the same time driving the locking head to rotate into the locking groove and lock it against the driving body. Therefore, during the entire use process, it is only necessary to manually rotate the trigger member once to drive the movable clamp away from the fixed clamp, which is more convenient to operate and more responsive.

DETAILED DESCRIPTION

[0038] 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.

[0039] 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.

[0040] See also Figures 1 to 4The present invention provides a technical solution: a quick locking device, comprising a base 1 and a shell 2 fixed on the base 1 by screws, wherein the base 1 is a threaded quick-release base, and in this embodiment, the base 1 and the shell 2 are circular as a whole, and can of course be designed into any shape as needed, such as a square or a strip, and the top of the shell 2 has a fixed chuck 3, and a movable chuck 4 is inserted on the side of the shell 2 opposite to the fixed chuck 3;

[0041] A driving body 5 is integrally formed on one side of the movable chuck 4 facing the housing 2. The driving body 5 described in the present application document is in the shape of a long strip and connected with the movable chuck 4 to form a T-shaped structure. The driving body 5 may also be in other shapes, such as an arc or annular structure.

[0042] A trigger member 6 is installed at the center of the base 1 through a bearing, and the trigger member 6 is located below the driving body 5. The trigger member 6 described in the present application document is an island in a circular ring, and the trigger member 6 can also be other shapes, such as an arc structure that can rotate around the center of the base 1.

[0043] A clutch positioning column 10 is integrally formed on the top of the trigger member 6, and an oblique groove A8 and an oblique groove B9 are provided on the bottom surface of one end of the driving body 5 close to the movable chuck 4. The oblique groove A8 and the oblique groove B9 are connected to form a "sickle"-shaped groove body on the bottom surface of the driving body 5. The radius of the curve formed by connecting the center points of the entrance end of the oblique groove A8 and the terminal end of the oblique groove B9 along the direction of the groove body gradually decreases, and the movement trajectory of the clutch positioning column 10 is always opposite to the groove wall of the oblique groove B9;

[0044] When the trigger member 6 rotates to drive the clutch positioning column 10 from the inclined groove A8 into the inclined groove B9, since the movement trajectory of the clutch positioning column 10 is always opposite to the groove wall of the inclined groove B9, the terminal end of the inclined groove B9 is biased toward the rotation center direction of the trigger member 6, and then when the clutch positioning column 10 moves along the inclined groove B9, it can push the driving body 5 to move outward to drive the movable chuck 4 away from the fixed chuck 3. Conversely, when the trigger member 6 rotates in the opposite direction, it can drive the movable chuck 4 to approach the fixed chuck 3. The two ends of the inclined groove A8 and the inclined groove B9 have a height difference in the vertical plane, and the height difference determines the displacement distance of the driving body 5.

[0045] See also Figures 2 to 5 The bottom surface of one end of the driving body 5 away from the inclined groove A8 is integrally formed with a protrusion A11 and a protrusion B12, and a locking groove 13 for plugging and matching with the locking head 7 is formed between the protrusion A11 and the protrusion B12;

[0046] The outer edge of the trigger member 6 is provided with a locking head 7, and the locking head 7 is in the shape of an arc blade. In a top view, when the trigger member 6 rotates counterclockwise or clockwise under the action of an external force, on the one hand, the clutch positioning column 10 cooperates with the inclined groove to move the driving body 5 to drive the movable clamp 4 away from the fixed clamp 3, open the dovetail groove of the clamp seat, or drive the movable clamp 4 to approach the fixed clamp 3 to clamp the camera quick release plate;

[0047] On the other hand, when the trigger member 6 rotates counterclockwise, it drives the locking head 7 to disengage from the locking groove 13, and the driving body 5 can then move. When the trigger member 6 rotates clockwise and drives the locking head 7 to insert into the locking groove 13, the locking head 7 and the driving body 5 are abutted against each other, providing an outward force to lock the driving body 5, thereby achieving the locking of the camera quick release plate.

[0048] See also Figures 4 to 6 A mounting column 14 is fixedly connected to the inner side of the base 1, a support ear 15 is fixedly provided on the outer circumferential surface of the trigger member 6, and a tension spring 16 is installed between the mounting column 14 and the support ear 15;

[0049] A limit mechanism 31 is installed on the movable clamp 4, and a limit hole 20 is provided on the housing 2. When the driving body 5 moves outward under the action of the trigger member 6 and reaches the maximum stroke, the tension spring 16 is stretched, and the limit mechanism 31 extends into the limit hole 20 to limit the movement and reset of the movable clamp 4. When the camera quick-release plate is installed in the clamp seat, the limit mechanism 31 can be pressed downward to release the limit of the limit mechanism 31. At this time, the tension spring 16 deforms back to its original shape to pull the trigger member 6 to rotate clockwise. When the trigger member 6 rotates clockwise, on the one hand, the driving body 5 is moved by the clutch positioning column 10 to drive the movable clamp 4 to approach the fixed clamp 3 for clamping;

[0050] On the other hand, the trigger member 6 rotates and drives the locking head 7 to be inserted into the locking groove 13, and locks against the driving body 5 to complete the fixation of the camera quick release plate.

[0051] See also Figure 6 , Figure 8 , Fig. 9 and Fig.10 The movable chuck 4 is integrally formed with a socket 17 on one side of the housing 2, and the socket 17 is provided with a mounting groove 18 extending therethrough from top to bottom, and the limiting mechanism 31 includes an elastic stopper installed in the mounting groove 18;

[0052] The housing 2 is provided with a slide groove 19 connected to the limiting hole 20 along the moving direction of the movable clamp 4. When the movable clamp 4 moves to align the elastic stopper with the limiting hole 20, the elastic stopper pops out to limit the movable clamp 4 from moving and resetting.

[0053] See also Figure 8 and Fig.10 The elastic stop member includes a sleeve A21 and a sleeve B22 arranged up and down, and a spring 23 is installed in both the sleeve A21 and the sleeve B22;

[0054] A positioning pin is fixedly arranged on the top of the sleeve B22. In this embodiment, the positioning pin is cross-shaped. The positioning pin includes an insert block A24 that is slidably matched with the slide groove 19. An insert block B25 is integrally formed on the side of the insert block A24. The top surface of the insert block B25 is lower than the top surface of the insert block A24 and abuts against the housing 2 under the action of the spring 23.

[0055] When the driving body 5 pushes the movable clamp 4 away from the fixed clamp 3 under the action of the trigger member 6, the insert block A24 slides along the slide groove 19. When the movable clamp 4 moves to the farthest stroke, the insert block B25 is aligned with the limiting hole 20, and the positioning pin is pushed upward under the force of the deformation of the spring 23, so that the insert block B25 enters the limiting hole 20. At this time, the insert block B25 is against the housing 2 under the horizontal reset force generated by the deformation of the tension spring 16, thereby limiting the movement of the movable clamp 4 and facilitating the one-handed operation of installing the camera quick release plate.

[0056] See also Figure 1 , Figure 2 , Figure 6 and Fig. 9 The outer circumferential surface of the housing 2 is provided with a sliding groove 26 which penetrates inside and outside. A wrench 27 is installed in the sliding groove 26. One end of the wrench 27 is located outside the housing 2, and the other end extends into the housing 2 and is fixedly connected to the trigger member 6. Specifically, the rotation angle of the trigger member 6 can be limited by the sliding groove 26. The maximum strokes at both ends of the sliding groove 26 correspond to the locking and opening states of the movable chuck 4, respectively. The wrench 27 is conducive to turning the trigger member 6 to rotate.

[0057] Working principle of the present invention: The initial state of the trigger member 6 of the present invention is as follows: Figure 4As shown in the figure (locked state), when the trigger member 6 is turned counterclockwise by the wrench 27, the trigger member 6 stretches the tension spring 16 when it rotates counterclockwise, and when the trigger member 6 rotates, on the one hand, it drives the locking head 7 to rotate synchronously, so that the locking head 7 moves out of the locking groove 13 to release the locking of the driving body 5, and on the other hand, it drives the clutch positioning column 10 to move from the inclined groove A8 to the inclined groove B9 to move the driving body 5 outward, so as to drive the movable clamp 4 away from the fixed clamp 3, as shown in the figure. Figure 5 As shown;

[0058] When the movable chuck 4 is away from the fixed chuck 3, the insert block A24 slides along the slide slot 19, and when the wrench 27 rotates counterclockwise to reach the farthest stroke, Figure 6 and Figure 7 As shown, at this time, the movable clamp 4 moves so that the plug block B25 is aligned with the limiting hole 20, and the positioning pin is pushed upward under the deformation force of the spring 23, so that the plug block B25 enters the limiting hole 20. The plug block B25 is against the housing 2 under the horizontal reset force generated by the deformation of the tension spring 16 to limit the movement and reset of the movable clamp 4. At this time, the camera quick release plate can be installed in the dovetail groove formed by the two clamps;

[0059] During the installation process, the camera quick-release plate presses downward the insert blocks A24 located on both sides of the movable clamp 4, so that the insert blocks B25 are downwardly disengaged from the limiting holes 20. At this time, the trigger member 6 is pulled and quickly rotated clockwise to reset under the action of the tension spring 16 deforming back to its original state. When the trigger member 6 rotates clockwise, on the one hand, the clutch positioning column 10 moves from the inclined groove B9 to the inclined groove A8 to move the driving body 5 inward, thereby driving the movable clamp 4 to quickly reset close to the fixed clamp 3 to clamp the camera quick-release plate.

[0060] On the other hand, the locking head 7 is screwed into the locking groove 13 and abuts against the driving body 5 under the drive of the rapid rotation of the trigger member 6, thereby providing an outward force to lock the driving body 5, ensuring the stability of the camera quick release plate installation and realizing the rapid installation and locking of the camera quick release plate.

[0061] See also Fig.11 The present invention also provides a technical solution: a photographic kit, including a planar thrust pan-tilt head 28, the planar thrust pan-tilt head 28 including the quick locking device as described above, the planar thrust pan-tilt head 28 is threadedly connected to the bottom of the base 1, and the pan-tilt head with a folder holder of the present application can quickly install the camera quick-release plate on the clamp seat, and then quickly install the photographic equipment, which is more convenient to operate and improves work efficiency and user experience.

[0062] See also Figures 12 to 15 The present invention also provides a technical solution: a photographic kit, comprising a camera conversion clamp seat 29 which is square in shape as a whole, wherein the base 1 of the camera conversion clamp seat 29 adopts a dovetail groove quick-release base, and the camera conversion clamp seat 29 includes the quick locking device as described above, and the difference from the quick locking device is that the limiting mechanism 31 is installed on the driving body 5, and the limiting mechanism 31 adopts the cooperation of a spring and a cylindrical or other shaped pin, and when the driving body 5 is pushed outward by the trigger member 6 to reach the maximum stroke (at this time, the movable clamp head 4 is away from the fixed clamp head 3 to open the dovetail groove of the clamp seat), the pin in the limiting mechanism 31 is generated by the deformation of the spring. Under the action force, it moves upward and is inserted into the limiting hole 20 on the shell 2 to limit the movement of the driving body 5. When the camera quick-release plate is installed in the dovetail groove, the pin can be pressed downward. At this time, the tension spring 16 deforms and pulls the trigger member 6 to rotate and toggle the driving body 5 to quickly move and reset, so that the movable clamp 4 is close to the fixed clamp 3 to quickly clamp the camera quick-release plate and lock it. Its working process is the same as that of the quick locking device, and no further details will be given here. The limiting mechanism 31 can be set on the driving body 5 or other positions according to functional requirements, so as to achieve the purpose of quickly installing photographic equipment on the camera conversion clamp 29 and improving work efficiency and user experience.

[0063] See also Fig.16 and Fig.17 The present invention also provides a technical solution: a photographic kit, comprising a quick installation plate 30, the quick installation plate 30 comprising the quick locking device as described above, the shell 2 of the quick installation plate 30 is rectangular as a whole, and the quick locking device installed at its end is the same as the quick locking device used in the camera conversion clamp 29, so as to achieve the purpose of quickly installing photographic equipment and improving work efficiency and user experience.

[0064] 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.
