Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary photographic equipment, 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 mounted on a bracket for use, it is basically inseparable from the clamping of the clamp. Most existing camera clamps are knob-pushing locking types. When locking, the movable clamp is driven to move and 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, resulting in low efficiency. Utility Model Content

[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 of the knob-pushed camera clamp, which is cumbersome to repeatedly turn the knob when locking, and the movable clamp moves slowly, resulting in slow locking and unlocking and low efficiency.

[0004] The utility model is achieved through the following technical solutions:

[0005] A quick locking device comprises a base and a shell fixed to 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 trigger member mounted on the base for moving the driving body to drive the movable chuck away from or close to the fixed chuck for clamping;

[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 the driving body is provided with an inclined slot A and an inclined slot B connected to the inclined slot A. 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 moves from the inclined slot A into the inclined slot B 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 post 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 post 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. 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 photographic kit includes a camera conversion clamp, wherein the camera conversion clamp includes the quick locking device as described above.

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

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

[0017] 1. When the trigger member rotates counterclockwise, it can toggle the driving body to drive the movable clamp away from the fixed clamp, quickly unlocking the clamp seat. The camera quick release plate can then be installed into the dovetail groove formed by the two clamps. After installation, the trigger member is toggled clockwise to reset. When the trigger member rotates, it toggles the driving body to drive the movable clamp to quickly reset and move it closer to the fixed clamp to clamp the camera quick release plate. The locking head is inserted into the driving body and abuts against the driving body to lock the camera quick release plate, thereby quickly and stably locking 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 utility model only needs to turn the trigger member to rotate to achieve the 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 providing the limit mechanism, the movable clamp can be restricted from moving and resetting when the movable clamp moves away from the fixed clamp and reaches the maximum stroke. When the camera quick-release plate is installed in the dovetail groove formed by the two clamps, the limit mechanism can be pressed downward to release the limit. 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 with the driving body. Therefore, during the entire use process, the trigger member only needs to be manually rotated 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 variations in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes and are not intended to limit the present invention.

[0039] In the description of this application, the terms "upper" and "lower" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. These are only for the convenience of describing this 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. Therefore, they should not be understood as limitations on this application.

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

[0041] A driving body 5 is integrally formed on the side of the movable chuck 4 facing the housing 2. The driving body 5 described in this application document is in the shape of an elongated strip and is connected to 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 mounted at the center of the base 1 via a bearing. The trigger member 6 is located below the driving body 5. The trigger member 6 described in this application document is in the shape of an island in a circular ring. The trigger member 6 may also be in other shapes, such as an arc-shaped structure that can rotate around the center of the base 1.

[0043] A clutch positioning post 10 is integrally formed on the top of the trigger member 6. An oblique groove A8 and an oblique groove B9 are formed on the bottom surface of the 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 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 gradually decreases along the direction of the groove body. The movement trajectory of the clutch positioning post 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 close to 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 cooperating 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, which is in the shape of an arc-shaped blade. When the trigger member 6 is rotated counterclockwise or clockwise under the action of an external force in a top view, 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, thereby opening the dovetail groove of the clamp seat or driving 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 The base 1 is fixedly connected to an inward side with a mounting post 14, and 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 post 14 and the support ear 15;

[0049] A limiting mechanism 31 is installed on the movable chuck 4, and a limiting 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 limiting mechanism 31 extends into the limiting hole 20 to limit the movement and reset of the movable chuck 4. When the camera quick-release plate is installed in the clamp seat, the limiting mechanism 31 can be pressed downward to release the limit of the limiting 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 chuck 4 to approach the fixed chuck 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 、 Figure 9 and Figure 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 slot 18 extending therethrough from top to bottom. The limiting mechanism 31 includes an elastic stopper installed in the mounting slot 18 ;

[0052] The housing 2 is provided with a slide groove 19 connected to the limiting hole 20 along the movement direction of the movable clamp 4. When the movable clamp 4 moves so that the elastic stopper is aligned with the limiting hole 20, the elastic stopper pops out to limit the movement and reset of the movable clamp 4.

[0053] See also Figure 8 and Figure 10 The elastic stop member includes a sleeve A21 and a sleeve B22 arranged in an upper and lower manner, and a spring 23 is installed in both the sleeve A21 and the sleeve B22;

[0054] A positioning pin is fixedly provided on the top of the sleeve B22. In this embodiment, the positioning pin is cross-shaped and includes an insert block A24 that slidably engages 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 is abutted 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 pushes the positioning pin 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, limiting the movement of the movable clamp 4, making it convenient for one-handed operation to install the camera quick release plate.

[0056] See also Figure 1 、 Figure 2 、 Figure 6 and Figure 9 The outer circumferential surface of the housing 2 is provided with a sliding groove 26 extending therethrough, with a wrench 27 inserted into 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 sliding groove 26 can limit the rotation angle of the trigger member 6. The maximum travels at both ends of the sliding groove 26 correspond to the locked and unlocked states of the movable chuck 4, respectively. The wrench 27 facilitates the rotation of the trigger member 6.

[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 (locked state), when the trigger member 6 is rotated 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 lock of the driving body 5, and on the other hand, it synchronously 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, driving the movable clamp 4 away from the fixed clamp 3, as shown in FIG. Figure 5 As shown;

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

[0059] During the installation process, the camera quick release plate presses downwardly 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 deformation of the tension spring 16 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 slot B9 to the inclined slot A8, thereby moving 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 under the drive of the rapid rotation of the trigger member 6 and abuts against the driving body 5, 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 Figure 11 The utility model 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 the folder holder of the present application can be quickly installed on the clamp seat, and then the photographic equipment can be quickly installed, the operation is more convenient, and the work efficiency and user experience are improved.

[0062] See also Figures 12 to 15 The present invention also provides a technical solution: a photographic kit, comprising a camera conversion clamp 29 that is square in shape as a whole, wherein the base 1 of the camera conversion clamp 29 adopts a dovetail groove quick-release base, and the camera conversion clamp 29 includes the quick locking device as described above. Unlike the quick locking device, 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. When the driving body 5 is pushed outward by the trigger member 6 to reach the maximum stroke (at this time, the movable clamp 4 is away from the fixed clamp 3 to open the dovetail groove of the clamp), the pin in the limiting mechanism 31 is deformed by the spring to generate a Under the action of , it moves upward and inserts 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 squeezed 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 Figure 16 and Figure 17 The utility model also provides a technical solution: a photographic kit, including a quick-installation plug-in plate 30, the quick-installation plug-in plate 30 includes the quick-locking device as described above, the shell 2 of the quick-installation plug-in 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 replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
