[0002] Photographic equipment is widely used in people's lives, mainly for taking pictures, recording videos, etc., to record people's lives. In order to facilitate the replacement of the photographic equipment, the photographic equipment is usually installed on a quick-release plate, and then the quick-release plate is detachably installed on a fixed installation position. The disassembly and assembly of the photographic equipment can be realized by the disassembly and assembly of the quick-release plate and the installation position. The existing quick-release plate is clamped with a contact on the installation position through a first card slot provided, and the control switch is connected with the contact through a linkage mechanism for controlling the movement of the contact to lock or unlock the quick-release plate. However, when pressing the control switch to unlock, the control switch will generate damping through the elastic action of the linkage mechanism, and it is necessary to keep pressing the control switch until the quick-release plate is disassembled before releasing, which is inconvenient to use and the user experience is poor. Summary of the Invention

[0041] Embodiment 1

[0042] As Figure 1 And Figure 2 Shown, this embodiment provides a trigger-type quick disassembly and assembly structure. When unlocking, the quick-installation part 2 can be disassembled by pressing the locking part 5 in place once, without having to keep pressing the locking part 5 all the time, which is convenient to use and provides a good user experience.

[0043] The above-mentioned trigger-type quick disassembly and assembly structure includes a quick-release base 1, a quick-mounting part 2, a locking part 5, a first elastic part 6, a second elastic part 7 and a limiting part 9. Among them, the quick-mounting part 2 is connected to the photographing device through the provided mounting mechanism. The photographing device can be a device such as a camera or a mobile phone. In this embodiment, the photographing device uses a camera. The quick-release base 1 and the quick-mounting part 2 are cooperatively inserted, that is, the quick-mounting part 2 can be mounted on the quick-release base 1 or detached from the quick-release base 1, so that the camera can be disassembled and assembled on the quick-release base 1.

[0044] As Figure 1 shown, there are many structures of the mounting mechanism, such as a magnetic attraction structure, a threaded connection structure, etc. The mounting mechanism of this embodiment includes a connecting screw 3. The quick-mounting part 2 is provided with a strip-shaped limiting groove 2a. The diameter of the head of the connecting screw 3 is larger than the width of the strip-shaped limiting groove 2a. For the convenience of clear narration, it is defined that the side of the quick-mounting part 2 close to the quick-release base 1 is the bottom, and the side far from the quick-release base 1 is the top. The connecting screw 3 passes through the strip-shaped limiting groove 2a from the bottom of the quick-mounting part 2 to the top of the quick-mounting part 2. The strip-shaped limiting groove 2a catches the head of the connecting screw 3. The rod part of the connecting screw 3 is provided with an external thread, which is threadedly connected to the threaded hole opened on the camera, so that the camera is connected to the quick-mounting part 2.

[0045] As Figure 5 shown, for the convenience of narration, it is defined that in the first direction, the direction opposite to the unlocking of the locking part 5 is the positive direction of the X axis, and the direction of unlocking of the locking part 5 is the negative direction of the X axis; in the second direction, the direction from the quick-release base 1 to the quick-mounting part 2 is the positive direction of the Z axis, and the reverse direction is the negative direction of the Z axis; the direction in which the quick-mounting part 2 is inserted into the quick-release base 1 is the Y axis direction, and the Y axis direction is perpendicular to the first direction and the second direction at the same time.

[0046] As Figure 4 shown, the quick-release base 1 is provided with a limiting hole 1a and a through hole 1b. The bottom of the quick-mounting part 2 is also provided with a locking groove 2b.

[0047] As Figure 3 shown, the quick-release base 1 includes a first end face 20 and a second end face 30 which are oppositely arranged. The second end face 30 is open and extends towards the first end face 20 to form an installation cavity, and is provided with a limiting hole 1a and a through hole 1b that penetrate to the first end face 20. The second end face 30 is provided with a bottom cover 4. The bottom cover 4 is installed on the quick-release base 1 through a plurality of screws to enclose a plurality of components in the installation cavity. Components such as the first elastic part 6, the second elastic part 7 and the limiting part 9 are all arranged in the installation cavity.

[0048] As Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 13As shown, the locking member 5 movably penetrates the quick-release base 1 in the first direction. The locking member 5 includes a handle 5a and a driving member 5b connected to each other. The handle 5a penetrates one side of the quick-release base 1 and is connected to the driving member 5b. The driving member 5b is disposed in the installation cavity. Pushing the handle 5a can drive the driving member 5b to move back and forth in the installation cavity in the first direction. A clamping structure 5c and a locking stud 10 are provided on the driving member 5b. The locking stud 10 penetrates the limiting hole 1a and extends from the first end face 20. The locking stud 10 can move to the locking position and the unlocking position in the limiting hole 1a. When the locking stud 10 is in the locking position, it is cooperatively connected with the locking groove 2b of the quick-mounting member 2, so that the quick-release base 1 and the quick-mounting member 2 are connected and installed. When the locking stud 10 is in the unlocking position, the locking stud 10 disengages from the locking groove 2b. At this time, the quick-mounting member 2 can be pulled out and disassembled from the quick-release base 1.

[0049] The limiting member 9 movably penetrates the quick-release base 1 in the second direction perpendicular to the first direction, that is, from the Z-axis direction. The clamping of the limiting member 9 and the clamping structure 5c includes a first clamping state and a second clamping state.

[0050] As Figure 5 shown, a first elastic member 6 is disposed between the driving member 5b and the inner side wall of the quick-release base 1 for pressing the driving member 5b to move in the first direction. A second elastic member 7 is disposed on the limiting member 9 for driving the limiting member 9 to move in the second direction. The first elastic member 6 and the second elastic member 7 cooperate to switch the clamping state between the limiting member 9 and the driving member 5b.

[0051] As Figure 7 、 Figure 8 and Figure 9 shown, when the handle 5a is pushed to move the driving member 5b in the negative X-axis direction until the driving member 5b and the limiting member 9 are in the first clamping state, since the locking stud 10 is disposed on the driving member 5b and moves synchronously with the driving member 5b, the locking stud 10 moves to the unlocking position and disengages from the locking groove 2b of the quick-mounting member 2. During this process, the driving member 5b compresses the first elastic member 6, and the second elastic member 7 presses the limiting member 9 to extend out of the first end face 20. In this state, the driving member 5b and the limiting member 9 are clamped, so that the driving member 5b cannot return. Even if the handle 5a is not pushed, the locking stud 10 is fixed and maintained in the unlocking position. The user can pull out and disassemble the quick-mounting member 2 from the quick-release base 1, which is convenient to use and provides a good user experience.

[0052] As Figure 13 shown, a hollow groove 2e extending along the top is formed at the bottom of the quick-mounting member 2. After the above-mentioned limiting member 9 extends out of the first end face 20, it is located in the hollow groove 2e and does not contact the bottom of the quick-mounting member 2.

[0053] As Figure 4 、 Figure 6 andFigure 9 As shown, after the above-mentioned locking stud 10 is unlocked, the quick-release member 2 can be detached from the quick-release base 1. The quick-release member 2 is gradually pulled out towards the outside, and the locking groove 2b is disengaged from the position corresponding to the locking stud 10 until the other end of the quick-release member 2 presses against the limiting member 9. The limiting member 9 retracts and compresses the second elastic member 7 until the limiting member 9 and the driving member 5b are in the second latching state. During this process, the first elastic member 6 presses the driving member 5b to move in the positive X-axis direction, and the locking stud 10 moves synchronously with the driving member 5b in the positive X-axis direction and returns to the locking position, preparing for the next installation of the quick-release member 2.

[0054] As Figure 10 shown, there are many structures of the above-mentioned limiting member 9. In one embodiment, the limiting member 9 includes a control stud 9b and a latching portion 9a arranged vertically. The latching portion 9a extends in the Y-axis direction, and the control stud 9b extends in the positive Z-axis direction. The control stud 9b penetrates the quick-release base 1, and the latching portion 9a is used to latch the first latching groove 5ba or the second latching groove 5bb, so that the limiting member 9 and the driving member 5b are switched between the first latching state and the second latching state.

[0055] As Figure 7 shown, in one embodiment, both the first latching groove 5ba and the second latching groove 5bb are provided on the side of the driving member 5b close to the limiting member 9. A non-closed notch is formed in this side in the Z-axis direction, and the notch penetrates the side to form the first latching groove 5ba.

[0056] In one embodiment, another notch is formed in the above-mentioned side in the X-axis direction, and the notch extends from the inside of the driving member 5b towards the direction away from the limiting member 9 to form the second latching groove 5bb.

[0057] As Figure 10 shown, the limiting member 9 is provided with a first accommodating groove 9c. One end of the second elastic member 7 abuts against the bottom of the first accommodating groove 9c, and the other end abuts against the bottom cover 4 provided on the quick-release base 1. The second elastic member 7 can drive the limiting member 9 to move in the Z-axis direction. The first accommodating groove 9c can cooperate with the second elastic member 7 to play a limiting role, so that the second elastic member 7 can stably drive the limiting member 9 to move in the Z-axis direction, and the control stud 9b extends out or is received in the first end face 20.

[0058] As Figure 5As shown, in one embodiment, the first elastic member 6 includes a first spring 6a and a second spring 6b. The quick-release base 1 is provided with a guiding screw 11 inserted into the driving member 5b in the first direction. The end of the quick-release base 1 is provided with a second accommodating groove and a third accommodating groove. The first spring 6a is disposed in the second accommodating groove, and the second spring 6b is disposed in the third accommodating groove. One end of the first spring 6a and the second spring 6b away from the driving member 5b is connected to the quick-release base 1. The second accommodating groove and the third accommodating groove can limit the first spring 6a and the second spring 6b, so that the first spring 6a and the second spring 6b can stably drive the driving member 5b to move in the X-axis direction.

[0059] As Figure 5 - Figure 9 shown, when the above-mentioned quick-installation member 2 is installed on the quick-release base 1, the clamping portion 9a is clamped in the second clamping groove 5bb, the control stud 9b retracts into the through hole 1b, and the locking stud 10 is located at the locking position. When it is necessary to disassemble the quick-installation member 2, push the handle 5a in the negative X-axis direction. The handle 5a pushes the driving member 5b to move in the negative X-axis direction. The position of the clamping portion 9a in the X-axis direction remains unchanged, and the second clamping groove 5bb moves relative to the clamping portion 9a in the negative X-axis direction. When it moves to a certain extent, the clamping portion 9a disengages from the second clamping groove 5bb, and the second elastic member 7 presses the limiting member 9, so that the clamping portion 9a is clamped in the first clamping groove 5ba. At the same time, the control stud 9b moves in the positive Z-axis direction and extends out of the first end face 20 along the through hole 1b. The locking stud 10 moves from the locking position to the unlocking position along with the driving member 5b and disengages from the locking groove 2b of the quick-installation member 2. After canceling the force applied to the handle 5a, the first spring 6a and the second spring 6b press the driving member 5b in the positive X-axis direction. The clamping portion 9a is clamped with the first clamping groove 5ba to abut against the driving member 5b, preventing the driving member 5b from moving in the positive X-axis direction, and the locking stud 10 will not move back to the locking position. The user can conveniently disassemble the quick-installation member 2 from the quick-release base 1, with a good experience.

[0060] During the process of disassembling the quick-installation member 2, the locking groove 2b of the quick-installation member 2 disengages from the position corresponding to the locking stud 10, so that even if the locking stud 10 moves to the locking position, it cannot connect to the locking groove 2b. When the quick-installation member 2 is about to be completely removed, the inner edge of the quick-installation member 2 presses the control stud 9b. The top of the control stud 9b is conical, which can play a guiding role and facilitate the retraction of the control stud 9b by extrusion. The quick-installation member 2 presses the control stud 9b to gradually move into the through hole 1b. When the control stud 9b is completely pressed into the through hole 1b, the clamping portion 9a is lower than the first clamping groove 5ba in the negative Z-axis direction. Under the elastic action of the first spring 6a and the second spring 6b, the driving member 5b moves in the positive X-axis direction. The second clamping groove 5bb is clamped with the clamping portion 9a to fix the clamping portion 9a, and the control stud 9b will not protrude again. The locking stud 10 moves to the locking position along with the driving member 5b.

[0061] AsFigure 7 As shown in Figure 13 FIG. 2, during the process of reinstalling the quick - mounting part 2 onto the quick - release base 1, the locking groove 2b of the quick - mounting part 2 can be re - engaged with the locking stud 10. Specifically, a guiding arc surface 2c is provided from the edge of the quick - mounting part 2 to the locking groove 2b. During the insertion process of the quick - mounting plate, the guiding arc surface 2c first presses the locking stud 10 to move a small distance L1 in the negative X - axis direction. When the locking stud 10 and the locking groove 2b are in corresponding positions, the locking stud 10 moves in the positive X - axis direction and snaps into the locking groove 2b, and the quick - mounting plate is connected to the quick - release base 1. It is defined that the clamping part 9a needs to move a distance of L2 to disengage from the second card slot 5bb. It should be noted that L1 < L2, so as to prevent the locking stud 10 from driving the driving part 5b to move excessively when moving in the negative X - axis direction, causing the clamping part 9a to disengage from the second card slot 5bb and the locking stud 10 being unable to move to the locking position.

[0062] Embodiment 2

[0063] As shown in Figure 11 FIG. Figure 12 3, in this embodiment, the driving part 5b can also be divided into two parts. The driving part 5b includes a first control part 5bc and a second control part 5bd. The handle 5a penetrates through the quick - release base 1 and is connected to the first control part 5bc. A strip - shaped groove is opened at one end of the first control part 5bc close to the second control part 5bd along the X - axis direction, and a first card slot 5ba is opened along the Z - axis direction. The strip - shaped groove abuts against the end of the second control part 5bd to form a second card slot 5bb.

[0064] In one embodiment, a fixed convex base and a third elastic member 8 are further provided in the quick - release base 1. One end of the third elastic member 8 is connected to the first control part 5bc, and the other end is connected to the fixed convex base. The third elastic member 8 can drive the first control part 5bc to move in the X - axis direction.

[0065] When the driving part 5b and the limiting member 9 change from the first clamping state to the second clamping state, the clamping part 9a of the limiting member 9 disengages from the first card slot 5ba. First, the third elastic member 8 drives the first control part 5bc to move in the positive X - axis direction. After the first control part 5bc moves, the first spring 6a and the second spring 6b drive the second control part 5bd to move in the positive X - axis direction. The locking stud 10 is provided on the first control part 5bc. As the first control part 5bc moves to the locking position and the second control part 5bd moves in the positive X - axis direction, it presses the first control part 5bc, and again drives the locking stud 10 to move in the direction of the locking position, making the movement of the locking stud 10 to the locking position more stable.

[0066] As shown in Figure 1 FIG. Figure 4As shown in the figure, there are many structures for the above-mentioned quick-release base 1 and quick-fitting member 2. In one embodiment, mounting seats are spaced apart on opposite sides of the quick-release base 1 in the X-axis direction, and dovetail grooves 1d are formed by recessing the two mounting seats in opposite directions. A protruding dovetail mounting portion 2f is provided between the top and bottom of the quick-fitting member 2, and the dovetail mounting portion 2f is inserted along the dovetail groove 1d, and the quick-fitting member 2 is cooperatively connected to the quick-release base 1.

[0067] When the quick-fitting member 2 is not installed on the quick-release base 1, if the handle 5a is pressed by some misoperation, the control stud 9b extends out of the first end face 20 again, and the locking stud 10 moves to the unlocking position. When installing the quick-fitting member 2, the end of the quick-fitting member 2 can squeeze the control stud 9b, so that the locking stud 10 retracts into the through hole 1b again, and the locking stud 10 moves to the locking position again, without affecting the installation of the quick-fitting member 2.

[0068] As Figure 13 shown in the figure, in one embodiment, an arc-shaped abutting surface 2d is provided on one side of the quick-fitting member 2 close to the outer edge of the quick-release base 1, and the position of the arc-shaped abutting surface 2d corresponds to the control stud 9b. The arc-shaped abutting surface 2d is used for guiding, so that the quick-fitting member 2 can more stably squeeze the control stud 9b, and the control stud 9b retracts into the through hole 1b.

[0069] Embodiment Three
