Referring to fig. 1, the present utility model provides a quick-mounting base 10 that is convenient to mount and dismount, the quick-mounting base 10 is mainly applied to a cradle head device in the field of photographing support auxiliary equipment, and the quick-mounting base 10 is used for mounting and locking a quick-mounting plate 20. In the process of changing different cameras and lenses of the tripod head, a customer only needs one trigger action to realize the whole process of installing and locking the quick mounting plate 20 by the quick mounting seat 10, so that the tripod head device can change the quick mounting plate 20 of different types more conveniently and rapidly, and then, the customer can obtain better shooting experience. Fig. 1 illustrates a quick assembly 1 comprising a quick mount 10 and a quick mount plate 20, the quick mount 10 being adapted to clamp the quick mount plate 20. At this time, the quick-mounting base 10 may be mounted on other external devices, or may be directly supported on a supporting surface. It should be noted that, in this embodiment, the type of the quick-mounting plate 20 connected to the quick-mounting base 10 is not limited, and the quick-mounting plate 20 should be understood in a broad sense in the present utility model, as long as it is an external device that can be cooperatively connected to the quick-mounting base 10.

The quick-assembling seat 10 comprises a seat body 100, a clamping part 200 and a locking part 300, wherein the seat body 100 is used as a supporting main body, the clamping part 200 is convexly arranged on one side of the seat body 100, the locking part 300 is movably arranged on the other side of the seat body 100, a clamping space is formed between the locking part 300 and the clamping part 200, and the quick-assembling seat 10 is used for clamping the quick-assembling plate 20 in the clamping space. The shape and the installation position of the clamping portion 200 are not limited, and the clamping portion 200 may be disposed at the edge of the base 100 for the installation position of the clamping portion 200, however, the clamping portion 200 may be disposed inside the base 100 in a protruding manner, and it is only necessary to satisfy that the clamping space formed by the clamping portion 200 and the locking portion 300 is required to be able to clamp the package board 20.

Referring to fig. 2, the seat 100 has a mounting cavity 111 and a avoidance notch 112, which are mutually communicated, the mounting cavity 111 is used for mounting the locking portion 300, and the avoidance notch 112 is used for the locking portion 300 to penetrate to protrude from the seat 100, so that the locking portion 300 can move relative to the seat 100 in the avoidance notch 112. In an embodiment, the base 100 includes a base 110 and a cover 120, where the cover 120 is detachably connected to the base 110 and encloses the mounting cavity 111 as described above, and the avoiding notch 112 is formed in the base 110.

The clamping portion 200 is connected to the base 110. Fig. 2 illustrates that the clamping portion 200 is disposed at the edge of the base 110 to fully utilize the installation space of the base 110, so that the whole of the quick-mounting base 10 tends to be more miniaturized. It is understood that in other embodiments, the clamping portion 200 may be disposed inside the base 110. In addition, fig. 2 also illustrates that a dovetail groove 210 is provided at a side of the clamping portion 200 facing the locking portion 300, and the dovetail groove 210 is used to engage the quick-mounting plate 20 with a dovetail structure to improve the stability of the quick-mounting plate 20 after installation.

The locking part 300 is disposed in the mounting cavity 111 and moves in the avoidance gap 112, and the locking part 300 can be triggered by a key to switch the quick-mounting seat 10 between the release state and the locking state. Fig. 3 illustrates the quick-mounting base 10 in an unclamped state, where the locking portion 300 and the clamping portion 200 are separated from each other, and a portion of the locking portion 300 protrudes from the base 100, so that a user can press the protruding portion of the locking portion 300 by using the quick-mounting plate 20, so that the locking portion 300 is triggered to approach the clamping portion 200, clamp the quick-mounting plate 20 between the locking portion 300 and the clamping portion 200, and the quick-mounting base 10 is switched to the locked state illustrated in fig. 4. It should be noted that, the protruding structure of the pressing locking portion 300 is only a specific triggering manner, and the triggering manner is not limited herein, and it is only required to satisfy that the quick-mounting seat 10 can be switched between the released state and the locked state by triggering the locking portion 300 through one key.

Referring to fig. 3 and 4, the locking part 300 can be triggered by a key to successively complete the first tilting and the second tilting towards the side of the clamping part 200, so as to clamp the quick-mounting plate 20 between the clamping part 200 and the locking part 300; wherein at the end of the first turning action, the quick-mounting plate 10 receives a horizontal clamping force from between the locking portion 300 and the clamping portion 200; at the end of the second tilting action, the quick-release plate 10 is also subjected to a vertical clamping force from between the locking portion 300 and the seat 100. Therefore, in the process of replacing the quick-mounting plate 20, the locking quick-mounting plate 20 can be mounted through only one triggering action, and compared with the process that the locking quick-mounting plate 20 can be mounted through triggering the locking part 300 and then rotating the locking knob back and forth, the scheme can continuously complete the overturning action of the locking part 300 towards the side of the clamping part 200 through only one key to trigger the locking part 300, so that the quick-mounting plate 20 is clamped between the clamping part 200 and the locking part 300, and the scheme obviously simplifies the operation steps. The present solution also enables the mounting and locking of the quick-release plate by means of a triggering action, on the premise of ensuring a quick-release plate 20. In addition, since the locking portion 300 can not only be turned toward the side where the clamping portion 200 is located for the first time to approach the clamping portion 200, but also the locking portion 300 can be turned further toward the side where the clamping portion 200 is located to approach the clamping portion 200, the locking portion 300 in this embodiment can also clamp the quick-acting plate 20 between the clamping portion 200 and the locking portion 300 more firmly.

Referring to fig. 2, the quick-mounting base 10 further includes a disc 400 and a first elastic member 500, wherein the disc 400 is rotatably connected to the base 100, and fig. 2 illustrates that the disc 400 is rotatably connected to the cover 120 and is accommodated in the mounting cavity 111. The first elastic member 500 is disposed between the disc 400 and the cover plate 120, and the locking portion 300 is engaged with the disc 400 before the locking portion 300 is turned over for the first time by being pressed by the quick-acting plate 20, and at this time, the first elastic member 500 accumulates elastic force. After the locking portion 300 is pressed by the quick-mounting plate 20 to complete the first overturning action, the first elastic member 500 releases the elastic force to drive the disc 400 to rotate, so that the disc 400 drives the locking portion 300 to overturn towards the clamping portion 200 for the second time, and the quick-mounting plate 20 is clamped between the clamping portion 200 and the locking portion 300. The first elastic member 500 may employ a torsion spring as shown in the drawings, and both ends of the torsion spring are connected to the disc 400 and the cover plate 120, respectively. Before the locking portion 300 is turned over by being pressed by the quick-acting plate 20, in order to achieve the locking of the locking portion 300 and the disc 400, in an embodiment, referring to fig. 5, a clamping groove 410 is provided at an edge of the disc 400, and the locking portion 300 is provided with a limiting block 320, where the limiting block 320 is locked in the clamping groove 410, so that the limiting block 320 can limit the rotation of the disc 400.

The disc 400 is further provided with a slant protrusion 420 with gradually changed thickness (gradually increased or gradually decreased thickness), after the disc 400 is released from the locking portion 300, fig. 6 illustrates that the slant protrusion 420 is located between the disc 400 and the locking portion 300, and as the disc 400 rotates, the slant protrusion 400 presses the locking portion 300 to continuously turn over toward the clamping portion 200, so as to reduce the clamping space and increase the clamping force, so as to clamp the quick-mounting plate 20 between the locking portion 300 and the clamping portion 200. When the thickness of the inclined protrusion 420 is large enough, the locking portion 300 can clamp the quick-mounting plate 20 between the locking portion 300 and the base 100, that is, the quick-mounting plate 20 is simultaneously subjected to the horizontal clamping force between the locking portion 300 and the clamping portion 200 and the vertical clamping force between the locking portion 300 and the base 100, which enables the quick-mounting plate 20 to be clamped on the quick-mounting base 10 more firmly without being easily separated. It should be noted that the ramp projections 420 are to be understood broadly in the present utility model, and in other embodiments the ramp projections 420 may be a gradual change in thickness of the disc 400 itself rather than an additional increase, as long as the gradual change, e.g., gradual increase or decrease, in size of the drive surface of the disc 400 for contacting the locking portion 300 in a direction along the thickness of the disc 400 is satisfied.

With continued reference to fig. 6, the locking portion 300 includes a clamping block 310 and a limiting block 320, where the clamping block 310 passes through the avoiding gap 112 and can turn in the avoiding gap 112, the limiting block 320 is clamped with the disc 400, the clamping block 210 will drive the locking portion 300 to turn over for the first time when pressed by the quick-mounting plate 201, and meanwhile, the limiting block 320 will turn over together and separate from the disc 400, and then the disc 400 will rotate under the elastic force of the first elastic member 500 to press the clamping block 310 to turn over for the second time near the clamping portion 200, so as to clamp the quick-mounting plate 20 between the clamping portion 200 and the clamping block 310 (and between the clamping block 310 and the base 110). In one embodiment, fig. 7 illustrates that the clamping block 310 includes a rotation shaft 311, a locking claw 312, and a trigger block 313, and the rotation shaft 311, the locking claw 312, and the trigger block 313 can move synchronously. Referring to fig. 2 and 8, the rotation shaft 311 is movably disposed in the mounting cavity 111, the rotation shaft 311 can rotate and move relative to the base 100, the locking claw 312 passes through the avoidance gap 112 and can turn in the avoidance gap 112, and the trigger block 313 is disposed inside the locking claw 312 and protrudes out of the base 100. The trigger block 313 can be pressed by the quick-acting plate 20 to drive the locking claw 312 and the rotating shaft 311 to turn around the central axis of the rotating shaft 311, and after the locking claw 312 finishes turning for the first time, the disc 400 rotates to drive the locking claw 312 to approach the clamping part 200 to finish turning for the second time, so that the quick-acting plate 20 is clamped between the clamping part 200 and the locking claw 312.

Referring to fig. 8, the quick-mounting base 10 further includes a second elastic member 600, where the second elastic member 600 is disposed between the base 100 and the rotating shaft 311, and when the locking portion 300 is pressed by the quick-mounting plate 20, the locking portion 300 can overcome the elastic resistance of the second elastic member 600 to complete the first overturn, so that the second elastic member 600 accumulates the first elastic force; when the locking part 300 is turned over for the second time by rotating the disc 400 to press the locking part 300 after the first time, the locking part 300 can further overcome the elastic resistance of the second elastic member 600 to continue turning over, so that the second elastic member 600 again accumulates the second elastic force. It should be noted that fig. 7 illustrates a case where two second elastic members 600 are provided at both ends of the rotation shaft 311, and of course, in other embodiments, the number of the second elastic members 600 may be one or more.

Referring to fig. 3 and 7 in combination, the second elastic member 600 includes a torsion spring section 610 and an extension section 620, which are connected and integrally formed, the torsion spring section 610 is disposed at the rotation shaft 311, and the extension section 620 is disposed in the mounting cavity 111 and abuts against the inner wall of the mounting cavity 111. The torsion spring section 610 rotates with the first rotation of the locking pawl 312 to accumulate the first elastic force when the locking portion 300 is pressed by the quick-release plate 20 during the first turning, and the torsion spring section 610 rotates with the second rotation of the locking pawl 312 to accumulate the second elastic force when the locking portion 300 turns over and locks the quick-release plate 20 for the second time. During the release of the quick release plate 10 to release the quick release plate 20, the locking portion 300 is turned away from the clamping portion 200 by the restoring force of the second elastic member 600 by the restoring force of the locking pawl 312. Specifically, during the reverse rotation of the disc 400 away from the clamping portion 200, the torsion spring section 610 of the second elastic member 600 releases the elastic force, and herein, for convenience of understanding, the first elastic force and the second elastic force released by the torsion spring section 610 are collectively defined as the restoring force. The locking part 300 can be turned over in a direction away from the clamping part 200 under the action of the restoring force to restore to the released state of the quick-mounting seat 10, and at this time, the disc 400 stops rotating and is clamped with the locking part 300. The shape and composition of the second elastic member 600 are not limited in the present utility model, and the second elastic member 600 may be a torsion spring, a spring, an elastic block, or other elastic members capable of generating elasticity, so long as the function of accumulating elasticity is satisfied, and the number of times the second elastic member 600 accumulates elasticity is not limited, so long as the process of accumulating elasticity at least twice is realized. The utility model adopts the integrally formed torsion spring structure as the second elastic piece 600, so that the second elastic piece 600 is simple and convenient to be matched with the mounting cavity 111 and the locking part 300, the structure inside the mounting cavity 111 is compact, and the process of continuously accumulating the elastic force twice can be effectively realized.

With continued reference to fig. 8, a stop block 113 protruding from the inner wall of the mounting cavity 111 is further disposed in the mounting cavity 111, and an extension 620 is limited between the inner wall of the mounting cavity 111 and the stop block 113, so as to prevent the second elastic member 600 from being deflected during accumulation and release of the elastic force. The number and shape of the stop blocks 113 are not limited, and may be two small cylinders as shown in fig. 7, or any geometric body protruding from the inner wall of the mounting cavity 111, or may be one, or more than two, or one row, so long as the stop blocks 113 are satisfied and can prevent the second elastic member 600 from being deviated during the process of accumulating and releasing the elastic force.

The quick-mounting seat 10 is further provided with a handle 700 connected with the disc 400, and the handle 700 can drive the disc 400 to rotate, so that the locking part 300 is driven to be close to or far from the clamping part 200, and the quick-mounting seat 10 can further lock or release the quick-mounting plate 20. Specifically, when the quick-mounting seat 10 continuously completes the first overturning and the second overturning towards the clamping part 200 through the one-key triggering locking part 300, the quick-mounting seat 10 clamps and locks the quick-mounting plate 20 between the locking part 300 and the clamping part 200, and the pulling handle 700 can drive the disc 400 to further rotate at this time, so that the locking part 300 continues to be close to the clamping part 200 for overturning, thereby reducing the clamping space, increasing the clamping force on the quick-mounting plate 20, and further clamping the quick-mounting plate 20 by the quick-mounting seat 10.

When the user needs to release the quick assembly plate 20, the user can drive the disc 400 to reversely rotate by pulling the handle 700, and in the process of reversely rotating the disc 400, the size of the driving surface of the disc 400, which is used for contacting the locking part 300, is gradually reduced along the thickness direction of the disc 400, at this time, the locking part 300 can return to be turned over to be far away from the clamping part 200 under the action of the restoring force released by the second elastic member 600 (refer to the torsion spring section 610), so as to increase the clamping space and reduce the clamping force, thereby releasing the quick assembly plate 20. When the disc 400 reversely rotates to a certain extent, the locking portion 300 returns and turns over to be clamped with the disc 400, so that the disc 400 cannot continue rotating, and the returning and turning over of the locking portion 300 can further facilitate the quick assembly plate 20 to vertically separate from the quick assembly seat 10 along the thickness direction of the quick assembly seat 10. In the process that the handle 700 drives the disc 400 to rotate reversely, the first elastic member 500 can overcome the reverse rotation resistance of the disc 400 to accumulate elastic force, so as to supply the driving force for the locking part 300 to move in the direction approaching to the clamping part 200 after being triggered by one key in the unfolded state. It should be noted that, for the present utility model, the handle 700 is only one specific embodiment of the quick-mounting base 10 of the present utility model capable of further locking the quick-mounting plate 20, the presence or absence of the handle 700 is not limited, and the shape and number of the handles 700 are not limited.

While the utility model has been described with reference to several exemplary embodiments, it is to be understood that the terminology used is intended to be in the nature of words of description and of limitation. As the present utility model may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
