Description

Technical Field

[0001] This utility model particularly relates to a quick-release structure for a photography platform. Background Technology

[0002] Existing quick-release mechanisms for camera tripods mostly employ a step-by-step operation: first, the quick-release plate is pushed into the base, then it is manually tightened or a separate locking mechanism is activated. This type of structure is cumbersome, slow, and carries the risk of the device coming loose in bumpy environments if the locking mechanism is forgotten. While some designs attempt automation, they are often complex in structure or rely on precision spring clips, which have insufficient locking force, are prone to wear, and have poor long-term reliability. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a quick-assembly structure for a photography platform.

[0004] A quick-installation structure for a photography platform includes a base with an internal mounting cavity and a mounting surface formed on its top for mounting the photography platform. A fixing element is fixedly mounted on the mounting surface. The base also has a first through-hole and a second through-hole. A positioning block is slidably disposed within the first through-hole, and a locking hook is movably disposed within the second through-hole. A linkage inclined plane mechanism is provided within the mounting cavity, and the locking hook and the positioning block are connected via the linkage inclined plane mechanism. When the locking hook is driven by an external force to move into the mounting cavity through the second through-hole, the linkage inclined plane mechanism drives the positioning block to extend through the first through-hole, protruding above the mounting surface, thereby clamping the photography platform together with the fixing element.

[0005] Preferably, the linkage inclined plane mechanism includes a mounting seat slidably disposed within the mounting cavity, a locking hook rotatably disposed on the mounting seat and capable of hooking onto the second through opening, and a first elastic element disposed between the mounting seat and the inner wall of the mounting cavity; the mounting seat is provided with a driving inclined plane, and the positioning block is correspondingly provided with a first inclined plane; when the locking hook is operated to release its hooking at the second through opening, the mounting seat is displaced under the restoring force of the first elastic element, causing the driving inclined plane to interact with the first inclined plane, thereby pushing the positioning block out of the first through opening.

[0006] Preferably, the positioning block includes a limiting strip, on which a base is rotatably mounted, and a travel groove that cooperates with the limiting strip is provided in the mounting cavity; the travel groove defines the positioning block having a first retracted position and a second extended position; a locking boss is provided on the base, and a first inclined surface is provided on the base; when the driving inclined surface interacts with the first inclined surface, it drives the base to move, causing the limiting strip to move from the first position to the second position in the travel groove, so that the locking boss extends out of the first through opening.

[0007] Preferably, the mounting base has a notch, and a fixed shaft is fixedly installed in the notch. The locking hook is rotatably mounted on the mounting base through the fixed shaft. A torsion spring is provided between the fixed shaft and the locking hook, and the torsion spring provides a restoring torque for the locking hook.

[0008] Preferably, the base is further provided with an operating component, which is connected to a reset inclined plane mechanism; operating the operating component can cause the reset inclined plane mechanism to act on the linkage inclined plane mechanism, driving the positioning block to retract along the first through opening, thereby releasing the locking of the photography platform.

[0009] Preferably, the reset inclined surface mechanism includes a second inclined surface disposed on the operating member that matches the driving inclined surface. When an external force is applied to the operating member, the second inclined surface cooperates with the driving inclined surface to drive the mounting base to move against the elastic force of the first elastic member, thereby causing the driving inclined surface to disengage from the first inclined surface.

[0010] Preferably, the reset inclined plane mechanism further includes a limiting channel formed on the base, a stop block is provided in the limiting channel, and a limiting hole is provided on the operating member. The stop block cooperates with the limiting hole to limit the movement stroke of the operating member.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This invention combines the installation and locking actions of the photography platform into one, requiring only a single push-in operation from the user to automatically complete positioning and locking. This integrated operation effectively avoids the risk of equipment loosening due to forgetting to perform a separate locking step, fundamentally improving safety and operational efficiency. Furthermore, the locking force of this application originates from the restoring force released by the pre-tightened first elastic element and is transmitted and converted through an inclined plane mechanism. This mechanical structure ensures that the generation of locking force does not depend on the user's subjective operating force, thus providing consistent, stable, and sufficient clamping force, guaranteeing the connection reliability of the photography platform under various working conditions.

[0019] A quick-assembly structure for a photography platform includes a base 1, with an internal mounting cavity 2 and a mounting plane 3 on its top for mounting the photography platform 1-1. A fixing member 4 is fixedly mounted on the mounting plane 3. The base 1 also has a first through opening 5 and a second through opening 6. A positioning block 51 is slidably disposed in the first through opening 5, and a locking hook 61 is movably disposed in the second through opening 6. A linkage inclined plane mechanism is provided in the mounting cavity 2, and the locking hook 61 and the positioning block 51 are connected by the linkage inclined plane mechanism. When the locking hook 61 is driven by an external force to move into the mounting cavity 2 through the second through opening 6, the linkage inclined plane mechanism drives the positioning block 51 to extend out through the first through opening 5, protruding from the mounting plane 3, thereby clamping the photography platform 1-1 together with the fixing member 4.

[0020] Furthermore, the linkage inclined plane mechanism includes a mounting base 71 slidably disposed within the mounting cavity 2, a locking hook 61 rotatably disposed on the mounting base 71 and capable of hooking onto the second through opening 6, and a first elastic element 72 disposed between the mounting base 71 and the inner wall of the mounting cavity 2; the mounting base 71 is provided with a driving inclined plane 710, and the positioning block 51 is correspondingly provided with the first inclined plane 510; when the locking hook 61 is operated to release its hooking at the second through opening 6, the mounting base 71 is displaced under the restoring force of the first elastic element 72, causing the driving inclined plane 710 to interact with the first inclined plane 510, thereby pushing the positioning block 51 out of the first through opening 5.

[0021] Furthermore, the positioning block 51 includes a limiting strip 512, on which a base 511 is rotatably disposed. The mounting cavity 2 is provided with a travel groove 513 that cooperates with the limiting strip 512. The travel groove 513 defines the positioning block 51 as having a first retracted position and a second extended position. The base 511 is provided with a locking boss 514, and the first inclined surface 510 is disposed on the base 511. When the driving inclined surface 710 interacts with the first inclined surface 510, it drives the base 511 to move, causing the limiting strip 512 to move from the first position to the second position in the travel groove 513, so that the locking boss 514 extends out of the first through opening 5.

[0022] Furthermore, the mounting base 71 has a notch 8, and a fixed shaft 81 is fixedly installed in the notch 8. The locking hook 61 is rotatably mounted on the mounting base 71 through the fixed shaft 81. A torsion spring 82 is provided between the fixed shaft 81 and the locking hook 61, and the torsion spring 82 provides a restoring torque for the locking hook 61.

[0023] Furthermore, the base 1 is also provided with an operating component 91, which is connected to a reset inclined surface mechanism; operating the operating component 91 can cause the reset inclined surface mechanism to act on the linkage inclined surface mechanism, driving the positioning block 51 to retract along the first through opening 5, so as to release the lock on the photography platform 1-1.

[0024] Furthermore, the reset inclined surface mechanism includes a second inclined surface 101 disposed on the operating member 91 and matched with the driving inclined surface 710. When an external force is applied to the operating member 91, it drives the mounting base 71 to move against the elastic force of the first elastic member 72 through the cooperation of the second inclined surface 101 and the driving inclined surface 710, thereby causing the driving inclined surface 710 to disengage from the first inclined surface 510.

[0025] Furthermore, the reset inclined plane mechanism also includes a limiting channel 111 opened on the base 1, a stop block 112 is provided in the limiting channel 111, and a limiting hole 910 is provided on the operating member 91. The stop block 112 cooperates with the limiting hole 910 to limit the movement stroke of the operating member 91.

[0026] The working principle of this utility model is as follows: This embodiment describes a quick-release structure for a photography platform 1-1. The base 1 has a flat mounting surface 3 on its top to support the photography platform 1-1. The fixing member 4 is a raised edge integrally formed on one end of the mounting surface 3. The first through opening 5 and the second through opening 6 are both rectangular through holes penetrating the top wall of the base 1. The structural cooperation principle of the positioning block 51 is as follows: the limiting strips 512 on both sides of the base 511 slide and cooperate with the travel groove 513 on the inner wall of the mounting cavity 2 of the base 1, and its movement stroke is limited between the "first position" and the "second position". The first inclined surface 510 is provided on the base 511, the base 511 is rotatably mounted on the limiting strip 512, and the locking boss 514 is provided on the base 511. The mounting seat 71 is slidably embedded in the mounting cavity 2. The first elastic member 72 is a spring, and its two ends abut against the inner wall of the mounting cavity 2 and the end face of the mounting seat 71, respectively. The locking hook 61 is mounted in the notch 8 of the mounting base 71 via the fixed shaft 81 and the torsion spring 82, allowing for smooth rotation and strong return. The torsion spring 82 ensures that the hook of the locking hook 61 can stably protrude and hook onto the edge of the second through opening 6 when there is no external force. This "hooking" state is key to achieving the "pre-tightening" and "triggering" functions.

[0027] The operating element 91 is slidably disposed within the limiting channel 111 of the base 1, and its inner second inclined surface 101 directly contacts the driving inclined surface 710 of the mounting base 71, forming the reset inclined surface mechanism. The internal stop block 112 on the base 1 engages with the limiting hole 910 on the operating element 91, ensuring that the operating element 91 slides within a preset safe travel range. The limiting channel 111 and the stop block 112 constitute a hard limit, preventing excessive pressure from damaging the internal mechanism.

[0028] The working principle is as follows: In the uninstalled state, under the torque of the torsion spring 82, the hook 61 protrudes from the mounting plane 3 and hooks onto the edge of the second through opening 6. This action locks the mounting base 71 in the retracted position, causing the first elastic element 72 to be compressed and in an energy-storing state. At this time, the positioning block 51 is not pushed and is in the first position of the stroke groove 513, with its locking boss 514 flush with or slightly lower than the mounting plane 3.

[0029] The quick-release plate of the photography platform 1-1 is pushed in along the mounting plane 3. The bottom surface of the quick-release plate serves as the sole operational input, contacting and pressing down the locking hook 61, forcing it to rotate around the fixed axis 81, thereby releasing its hook at the second through opening 6. At the instant the hook is released, the mounting base 71 loses its constraint and, driven by the restoring force of the first elastic element 72, slides forward rapidly as a whole. The sliding of the mounting base 71 causes the driving inclined surface 710 on it to engage in inclined plane transmission with the first inclined surface 510 on the base 511. Since the base 511 is rotatably mounted on the limiting strip 512, when the driving inclined surface 710 pushes the first inclined surface 510, it can cause the base 511 to rotate relative to the limiting strip 512. This causes the locking boss 514 to extend out of the first through opening 5 and protrude above the mounting plane 3. The locking boss 514 and the fixing member 4 work together to firmly clamp the photography platform 1-1 from both sides. The entire process is driven by stored elastic potential energy and is completed automatically. The user only needs to perform one action: "push in".

[0030] When the user needs to disassemble, pressing the operating member 91 causes it to slide along a predetermined stroke, constrained by the limiting channel 111 and the stop block 112. During this sliding process, the second inclined surface 101 on the operating member 91 interacts with the driving inclined surface 710 on the mounting base 71, overcoming the elastic force of the first elastic element 72 and pushing the mounting base 71 to slide back and reset. The retraction of the mounting base 71 causes the driving inclined surface 710 to disengage from the first inclined surface 510, the positioning block 51 loses its support, and the locking boss 514, under the action of gravity or its own small return spring, descends and retracts into the mounting cavity 2, releasing the clamp. At the same time, the locking hook 61 automatically resets under the action of the torsion spring 82, preparing for the next working cycle.

[0031] This invention combines the installation and locking actions of the photography platform 1-1 into one, requiring only a single push-in operation from the user to automatically complete positioning and locking. This integrated operation effectively avoids the risk of equipment loosening due to forgetting to perform a separate locking step, fundamentally improving safety and operational efficiency. Furthermore, the locking force in this application originates from the restoring force released by the pre-tightened first elastic element 72, and is transmitted and converted through an inclined plane mechanism. This mechanical structure ensures that the locking force is independent of the user's subjective operating force, thereby providing consistent, stable, and sufficient clamping force, guaranteeing the connection reliability of the photography platform 1-1 under various working conditions.

[0032] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
