Description

Technical Field

[0001] The present invention relates to the technical field of photographic equipment, and particularly relates to a quick-release mechanism. Background Art

[0002] The quick-release mechanism on a traditional camera tripod includes a panel base, a quick-release seat, and a buckle locking mechanism. A sliding groove is provided on the panel base, and the quick-release seat is horizontally slidably installed in the sliding groove. When the quick-release seat slides horizontally to the in-place position, the quick-release seat is locked on the sliding groove by using the buckle locking mechanism. When installing the quick-release seat, the quick-release seat can only be horizontally slid into the sliding groove of the panel base, and it is impossible to achieve the quick installation of the quick-release seat from top to bottom, resulting in a long installation time for the quick-release seat. For a photographer, some important photographic images may be missed during the relatively long assembly process of the quick-release seat, affecting the photographic experience.

[0003] To facilitate the quick installation of the quick-release seat from top to bottom on the panel base, some quick-release mechanisms are provided with a sliding block on the back of the panel base. One side of the sliding block is rotatably connected to a locking block. The buckle is connected to the side of the sliding block facing away from the locking block and can drive the movable block to slide. A return spring is elastically arranged between the sliding block and the panel base. The buckle has a locked state and a released state during rotation. When the buckle is in the locked state, the sliding block moves towards the buckle side, the return spring is compressed, and the sliding block drives the locking block to lock the quick-release seat in the card slot. When the buckle is in the released state, the return spring drives the sliding block and the locking block to move in the direction of releasing the quick-release seat. At this time, the quick-release seat is released, and the quick-release seat can be taken out from the card slot of the panel base.

[0004] For this kind of quick-release mechanism, although it can achieve the quick installation of the quick-release seat from top to bottom, when the buckle is in the locked state, the locking force applied by the buckle needs to be transmitted to the locking block through the sliding block, and then the locking block and the panel base press the quick-release seat from both sides to achieve locking. Since one end of the locking block is rotatably connected to the sliding block, there is inevitably a slight fitting gap between the locking block and the sliding block. When the movement distance of the sliding block pulled by the buckle from the released state to the locked state is a fixed value, the existence of this fitting gap will cause the actual movement distance of the locking block during the movement and locking process to be less than the movement distance of the buckle, and the actual locking force applied by the locking block to the quick-release seat will be slightly less than the locking force applied by the buckle, affecting the locking effect of the quick-release seat. Moreover, horizontally sliding the sliding block on the back of the panel base requires additional setting of a baffle and locking screws to limit the sliding block on the panel base, and more components need to be set, the overall structure is relatively complex, and the production cost is high. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the existing quick-release mechanism that can achieve quick installation of the quick-release seat from top to bottom, which has poor locking effect and complex locking structure, so as to provide a quick-release mechanism.

[0006] To solve the above technical problems, the technical solution of the present invention is as follows:

[0007] A quick installation mechanism includes a base, a movable block, a locking block, a quick installation seat and a trigger assembly; the movable block and the locking block are respectively located on opposite sides of the base, and the movable block and the locking block cooperate to form a dovetail groove on the front surface of the base. A rotating shaft is installed on the back surface of the base, and one end of the movable block is rotatably connected to the rotating shaft. A torsion spring is wound around the rotating shaft, one end of the torsion spring abuts against the base, and the other end abuts against the movable block. The elastic force of the torsion spring drives the movable block to rotate in the direction of pressing the base; the locking block is movably installed on one side of the base along the connection direction of the locking block and the movable block, and the quick installation seat is detachably connected to the dovetail groove; the trigger assembly includes a tension rod with one end connected to the base and passing through the locking block, and a trigger located on the side of the locking block facing away from the base and rotatably connected to the end of the tension rod; the trigger has a locking position and a release position during rotation. When the trigger is in the release position, the quick installation seat can be pressed into the dovetail groove from the front surface of the base. When the trigger is in the locking position, the trigger pushes the locking block to move towards the movable block, so that the locking block and the movable block cooperate to lock the quick installation seat in the dovetail groove.

[0008] Further, the movable block is provided with a movable block inclined surface forming one groove side wall of the dovetail groove, and the locking block is provided with a locking block inclined surface forming the other groove side wall of the dovetail groove; one side of the quick installation seat is provided with a first inclined surface that is inclined surface-mated with the movable block inclined surface, and the other side of the quick installation seat is provided with a second inclined surface that is inclined surface-mated with the locking block inclined surface.

[0009] Further, when the trigger is in the locking position, the movable block inclined surface and the first inclined surface are in an overcut state.

[0010] Further, one side of the movable block protrudes outwards to facilitate pressing the pressing buckle of the movable block.

[0011] Further, one side of the base facing the locking block is provided with a threaded connection hole and a guide groove. One end of the tension rod is threadedly and fixedly connected to the threaded connection hole, and the locking block is provided with a guide post that is matched with the shape of the guide groove and slidably connected in the guide groove.

[0012] Further, a return spring is elastically supported between the bottom of the guiding groove and the guiding post in the guiding groove. When the trigger is in the released position, the elastic force of the return spring drives the locking block to move away from the movable block.

[0013] Further, the trigger assembly further includes a trigger shaft fixedly connected to the end of the tension rod. One end of the trigger connected to the trigger shaft is an eccentric block, and the eccentric block is rotatably connected to the trigger shaft. When the trigger is in the released state, the proximal end of the eccentric block abuts against the locking block. When the trigger is in the locked state, the distal end of the eccentric block abuts against the locking block.

[0014] Further, a receiving groove is provided on one side of the locking block facing the trigger. The trigger assembly further includes a pressing block embedded in the receiving groove and sleeved on the outer periphery of the tension rod. The pressing block is disposed between the eccentric block of the trigger and the locking block.

[0015] Further, at least two elastic gaskets are further disposed between the pressing block and the bottom of the receiving groove.

[0016] Further, a rotating shaft hole is formed in the base, and both ends of the rotating shaft are fixed in the rotating shaft hole. An installation groove is provided on the back surface of the base. The rotating shaft passes through the installation groove. A connection hole is provided on the part of the back surface of the base where the installation groove is not provided, and a connection screw for connecting to an external pan-tilt is threadedly connected to the connection hole.

[0017] The technical solution of the present invention has the following advantages:

[0018] 1. The quick-release mechanism provided by the present invention includes a base, a movable block, a locking block, a quick-release seat and a trigger assembly. The movable block and the locking block are located on opposite sides of the base. The dovetail groove for locking the quick-release seat is formed by the cooperation of the movable block, the locking block and the base. The base only serves as the bottom wall of the dovetail groove, and the two opposite groove side walls of the dovetail groove are respectively formed by the movable block and the locking block. The movable block is rotatably connected to one side of the base through a rotating shaft and a torsion spring. Due to the rotatable combination design of the movable block, the quick-release seat can be quickly installed in the dovetail groove from top to bottom by pressing down. When locking the quick-release seat, rotate the trigger, and the trigger pushes the locking block to move towards the movable block. The cooperation between the locking block and the movable block can lock the quick-release seat in the dovetail groove. In this quick-release seat locking method, the locking force provided by the trigger only needs to drive the movement of one component, the locking block. The movement stroke of the trigger along the tension rod from the released position to the locked position is the movement stroke of the locking block. The locking force can be fully applied to the quick-release seat through the locking block, which is beneficial to improving the locking effect of the quick-release seat. Moreover, the overall structure is simple and the number of components is small, which is beneficial to reducing the production cost of the quick-release mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] As Figure 1 A quick-installation mechanism as shown in -4 includes a base 1, a movable block 2, a locking block 3, a quick-installation seat 4, and a trigger assembly 5. Among them, the base 1 is in a flat plate structure. The base 1 includes a front surface 1a and a back surface 1b arranged opposite to each other. The movable block 2 and the locking block 3 are respectively located on opposite sides of the base 1. The movable block 2 and the locking block 3 cooperate on the front surface 1a of the base 1 to enclose a dovetail groove. The front surface 1a of the base 1 forms the side wall of the dovetail groove, and the movable block 2 and the locking block 3 form the side wall of the dovetail groove. A rotating shaft 7 is installed on the back surface 1b of the base 1. One end of the movable block 2 is rotatably connected to the rotating shaft 7. A torsion spring 8 is wound around the rotating shaft 7. One end of the torsion spring 8 abuts against the base 1, and the other end abuts against the movable block 2. The elastic force of the torsion spring 8 drives the movable block 2 to rotate in the direction of pressing the base 1. The locking block 3 is movably installed on one side of the base 1 along the connection direction of the locking block 3 and the movable block 2. The quick-installation seat 4 is detachably connected to the dovetail groove. The trigger assembly 5 includes a tension rod 53 with one end connected to the base 1 and passing through the locking block 3, and a trigger 51 located on the side of the locking block 3 facing away from the base 1 and rotatably connected to the end of the tension rod 53. The trigger 51 has a locking position and a release position during rotation. When the trigger 51 is in the release position, the quick-installation seat 4 can be pressed into the dovetail groove from the front surface 1a of the base 1. When the trigger 51 is in the locking position, the trigger 51 pushes the locking block 3 to move towards the movable block 2, so that the locking block 3 and the movable block 2 cooperate to lock the quick-installation seat 4 in the dovetail groove.

[0029] In this embodiment, the movable block 2 is provided with a movable block inclined surface 21 forming one side wall of the dovetail groove, and the locking block 3 is provided with a locking block inclined surface 31 forming the other side wall of the dovetail groove; one side of the quick-installation seat 4 is provided with a first inclined surface 41 that is inclined surface-mated with the movable block inclined surface 21, and the other side of the quick-installation seat 4 is provided with a second inclined surface 42 that is inclined surface-mated with the locking block inclined surface 31. During the process of locking the quick-installation seat 4, the trigger 51 drives the locking block 3 to move through the tension rod 53. The locking block 3 presses the first inclined surface 41 on the quick-installation seat 4 through the locking block inclined surface 31, and cooperates with the movable block 2 to press the quick-installation seat 4 downward on the base 1. When the trigger 51 is in the locking position, the movable block inclined surface 21 and the first inclined surface 41 are in an overcut state.

[0030] In this embodiment, one side of the movable block 2 protrudes outward to facilitate pressing the pressing buckle 22 of the movable block 2.

[0031] In this embodiment, on one side of the base 1 facing the locking block 3, there are a threaded connection hole 12 and a guiding groove 13. One end of the tension rod 53 is fixedly connected to the threaded connection hole 12 by threading. On the locking block 3, there is a guiding post 32 that matches the shape of the guiding groove 13 and is slidably connected within the guiding groove 13. There are two guiding grooves 13, and correspondingly, there are also two guiding posts 32. The two guiding grooves 13 are located on opposite sides of the threaded connection hole 12. A return spring 6 that is elastically supported between the bottom of the guiding groove 13 and the guiding post 32 is provided in each guiding groove 13. When the trigger 51 is in the released position, the elastic force of the return spring 6 drives the locking block 3 to move away from the movable block 2.

[0032] In this embodiment, the trigger assembly 5 further includes a trigger shaft 52 fixedly connected to the end of the tension rod 53. One end of the trigger 51 connected to the trigger shaft 52 is an eccentric block, and the eccentric block is rotatably connected to the trigger shaft 52. When the trigger 51 is in the released state, the proximal end of the eccentric block abuts against the locking block 3. When the trigger 51 is in the locked state, the distal end of the eccentric block abuts against the locking block 3. The side surface of the locking block 3 facing the trigger 51 is an arc surface. To facilitate the trigger 51 to press the locking block 3, a receiving groove 33 is provided on the side of the locking block 3 facing the trigger 51. The receiving groove 33 is generally square, and the bottom of the receiving groove 33 is a flat surface. The trigger assembly 5 further includes a pressing block 54 embedded in the receiving groove 33 and sleeved on the outer periphery of the tension rod 53. The outer shape of the pressing block 54 is the same as that of the receiving groove 33. The pressing block 54 is disposed between the eccentric block of the trigger 51 and the locking block 3 to facilitate increasing the pressure-receiving area of the locking block 3 so that the locking block 3 can be better stressed.

[0033] Further, three elastic gaskets are disposed between the pressing block 54 and the bottom of the receiving groove 33. The three elastic gaskets can well eliminate the contact surface gap between the pressing block 54 and the locking block 3 by using their own elasticity and compressibility, so that the force on the pressing block 54 can be more smoothly transmitted to the locking block 3.

[0034] In this embodiment, a rotating shaft hole 11 is formed in the base 1, and both ends of the rotating shaft 7 are fixed in the rotating shaft hole 11. An installation groove is provided on the back surface 1b of the base 1. The rotating shaft 7 penetrates through the installation groove, and one end of the movable block 2 connected to the rotating shaft 7 exactly fills the installation groove. A connection hole is provided on the part of the back surface 1b of the base 1 where no installation groove is provided, and a connection screw 9 for connecting to an external cloud platform is threadedly connected to the connection hole. With such a design, since the structure of the base 1 is simple and there is no need to design complex structures such as sliding blocks inside the base 1, there is a large structural design space on the back surface 1b of the base 1. Therefore, it is convenient to set the connection screw 9 for connecting to the external cloud platform on the back surface 1b of the base 1, which can further enrich the usage scenarios of the quick-release mechanism.

[0035] The assembly process of this quick-release mechanism is as follows: When installing the quick-release seat 4, the buckle 51 is in the open state, and the quick-release seat 4 can be pressed down from top to bottom for installation. When the quick-release seat 4 presses the movable block 2, the movable block 2 rotates downward by a certain angle along the rotating shaft 7, and then the movable block 2 can avoid the quick-release seat 4. The quick-release seat 4 can be directly pressed down to the front surface 1a of the base 1. At this time, the movable block 2 is released from the pressure of the quick-release seat 4, and the movable block 2 rotates upward along the rotating shaft 7 under the action of the torsion spring 8, and part of the movable block 2 rotates above the quick-release seat 4; then press down the buckle 51, and under the action of the tension rod 53, the locking block 3 moves towards the movable block 2. After the inclined surface 31 of the locking block contacts the second inclined surface 42 of the quick-release seat 4, it drives the quick-release seat 4 to move towards the movable block 2 until the first inclined surface 41 of the quick-release seat 4 is pressed against the inclined surface 21 of the movable block. At this time, the locking block 3 can press the quick-release seat 4. At this time, when pressing down the movable block 2 again, since the inclined surface 21 of the movable block 2 and the first inclined surface 41 of the quick-release seat 4 are in an over-cut state, the movable block 2 cannot be pressed down; when releasing the quick-release seat 4, only need to loosen the buckle 51, and the locking block 3 moves away from the movable block 2 under the action of the return spring 6. When pressing down the movable block 2, the inclined surface 21 of the movable block is separated from the first inclined surface 41 of the quick-release seat 4, and at this time, the quick-release seat 4 can be taken out from bottom to top.

[0036] The quick-installation structure provided by the embodiment of the present invention has the movable block 2 and the locking block 3 located on opposite sides of the base 1. The dovetail groove for locking the quick-installation seat 4 is formed by the cooperation of the movable block 2, the locking block 3 and the base 1. Moreover, the base 1 only serves as the bottom wall of the dovetail groove, and the two opposite groove side walls of the dovetail groove are respectively formed by the movable block 2 and the locking block 3. The movable block 2 is rotatably connected to one side of the base 1 through a rotating shaft 7 and a torsion spring 8. Due to the rotatable combination design of the movable block 2, the quick-installation seat 4 can be quickly installed in the dovetail groove from top to bottom by pressing it downward; when locking the quick-installation seat 4, rotate the buckle 51, and the buckle 51 pushes the locking block 3 to move towards the movable block 2. The cooperation between the locking block 3 and the movable block 2 can lock the quick-installation seat 4 in the dovetail groove. In this way of locking the quick-installation seat 4, the locking force provided by the buckle 51 only needs to push one component, i.e., the locking block 3, to move. The movement stroke of the buckle 51 along the tension rod 53 when rotating from the release position to the locking position is the movement stroke of the locking block 3. The locking force can be fully applied to the quick-installation seat 4 through the locking block 3, which is beneficial to improving the locking effect of the quick-installation seat 4; moreover, the overall structure is simple and there are few components, which is beneficial to reducing the production cost of the quick-installation mechanism.

[0037] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
