Description

Technical Field

[0001] This application relates to the field of photographic equipment technology, and more particularly to a disassembly and assembly mechanism. Background Technology

[0002] To facilitate the quick installation of photographic equipment, such as cameras and camcorders, a quick-release plate is used to mount the equipment to the tripod and tripod. Generally, the quick-release plate is equipped with mounting screws, and the bottom of the camera, lens, or camcorder has threaded holes corresponding to the mounting screws. The camera or camcorder is mounted and fixed to the quick-release plate by the threaded engagement of the mounting screws with the threaded holes, and then the quick-release plate is used to fix the photographic equipment to the tripod.

[0003] Existing quick-release plates typically clamp into slots on a clamp, and the quick-release plate is locked to the clamp by adjusting a locking device. This type of quick-release plate requires constant adjustment of the locking device during installation and removal of photographic equipment, a time-consuming and inefficient process that causes inconvenience to users. Summary of the Invention

[0004] Therefore, it is necessary for the present invention to provide a disassembly and assembly mechanism that enables the rapid installation and disassembly of photographic equipment.

[0005] A disassembly / reassembly mechanism includes a housing, a locking element, an unlocking element, and a first elastic element. The housing includes a connecting portion for attaching external photographic equipment. The locking element is movably disposed within the housing. The unlocking element is rotatable relative to the housing and has a first limiting post that abuts against the locking element. The first elastic element is disposed within the housing, and the elastic deformation direction of the first elastic element is parallel to the rotation direction of the unlocking element. When an external force is applied to rotate the unlocking element to the unlocked position, the first limiting post pushes the locking element away from the connecting portion, and the first elastic element applies reverse damping to the unlocking element until it reaches the unlocked position. When the external force is released, the first elastic element pushes the unlocking element to rotate in the opposite direction, and the first limiting post pushes the locking element closer to the connecting portion.

[0006] Therefore, when it is necessary to install photographic equipment, the photographic equipment can be placed in the connecting part. The first elastic element applies damping to the unlocking element, causing the unlocking element to rotate to the locked position. During this process, the first limiting post pushes the locking piece to move towards the connecting part, so that the locking piece abuts against the outside of the photographic equipment, thereby achieving quick and automatic locking of the photographic equipment. When it is necessary to remove the photographic equipment from the above-mentioned disassembly and assembly mechanism, the unlocking element can be controlled to overcome the reverse damping of the first elastic element, so that the unlocking element rotates to the unlocked position, causing the first limiting post to push the locking piece to move away from the photographic equipment, so that the locking piece releases its abutment against the outside of the photographic equipment, thereby achieving quick release of the locking of the photographic equipment.

[0007] In one embodiment, the locking member includes a fastening part and a blocking part, the fastening part being disposed toward the connecting part, and when an external force rotates the unlocking member to the unlocking position, the first limiting post abuts against the blocking part.

[0008] In one embodiment, the housing is further provided with a groove, and the unlocking member is provided with a second limiting post facing the groove. One end of the first elastic member abuts against the second limiting post, and the other end abuts against a side wall of the groove. When an external force is applied to rotate the unlocking member to the unlocking position, the first elastic member is compressed by the unlocking member and the groove, and a reverse damping is applied to the unlocking member. When the external force is released, the first elastic member extends to the naturally unfolded state and pushes the unlocking member to rotate in the opposite direction.

[0009] In one embodiment, the housing includes an upper shell and a lower shell. The upper shell has a side facing away from the lower shell recessed to form the connecting portion. The side wall of the connecting portion has a side hole for the card to enter and exit. The side hole is provided in a one-to-one correspondence with the card. An accommodating space is formed between the upper shell and the lower shell to accommodate the card, the first elastic member, and part of the unlocking member.

[0010] In one embodiment, the unlocking element includes a rotating body and an extension, the rotating body being disposed on the outer periphery of the housing, and the extension extending into the accommodating space.

[0011] In one embodiment, the extension is provided with a second limiting post on one side facing the card.

[0012] In one embodiment, the extension is provided with the second limiting post on one side facing the card, and the upper shell is provided with the groove on one side facing the lower shell.

[0013] In one embodiment, the projections of the rotating body and the outer periphery of the housing are both circular, and the outer side of the rotating body is provided with anti-slip ridges.

[0014] In one embodiment, the connecting part is provided with a through hole, the connecting part includes a second elastic member and a top post, the top post is movably inserted through the through hole, and the two opposite ends of the second elastic member are respectively connected to the lower shell and the top post, wherein the second elastic member is used to push the top post through the through hole to abut against the photographic equipment.

[0015] In one embodiment, the lower shell is provided with a third limiting post, which is aligned with the through hole and passes through the second elastic member.

[0016] In one embodiment, the disassembly and assembly mechanism further includes a third elastic member abutting against one end of the latch away from the connecting portion. When the unlocking member is rotated to the unlock position, the first limiting post abuts against the blocking portion to compress the third elastic member. When the unlocking member is in the locked position, the first limiting post releases its contact with the blocking portion, and the third elastic member extends to a naturally unfolded state.

[0017] In one embodiment, the number of the card, the third elastic member, and the first limiting post are all four, and the four card pieces are arranged opposite each other in pairs, and the lines connecting the two pairs of opposite card pieces are perpendicular to each other.

[0018] In one embodiment, the blocking portion extends toward the first limiting post, and the sidewall of the blocking portion abutting the first limiting post is set at an acute angle to the extension direction of the third elastic member, wherein the tip of the acute angle faces the third elastic member.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] like Figures 1-14 As shown, this application provides a disassembly and assembly mechanism 10, including a housing 100, a locking member 200, an unlocking member 400, and a first elastic member 320. The housing 100 includes a connecting portion 111 for connecting external photographic equipment 20. The locking member 200 is movably disposed within the housing 100. The unlocking member 400 is rotatable relative to the housing 100. The unlocking member 400 is provided with a first limiting post 421 that abuts against the locking member 200. The first elastic member 320 is disposed within the housing 100. The elastic deformation direction of the first elastic member 320 is parallel to the rotation direction of the unlocking member 400. When an external force is applied to rotate the unlocking member 400 to the unlocked position, the first limiting post 421 pushes the locking member 200 away from the connecting portion 111, and the first elastic member 320 applies reverse damping to the unlocking member 400 until it reaches the unlocked position. When the external force is released, the first elastic element 320 pushes the unlocking element 400 to rotate in the opposite direction, and the first limiting post 421 pushes the locking element 200 closer to the connecting part 111.

[0039] Therefore, when it is necessary to install the photographic equipment 20, the photographic equipment 20 can be partially placed in the connecting part 111. The first elastic member 320 applies damping to the unlocking member 400, so that the unlocking member 400 rotates to the locking position. During this process, the first limiting post 421 pushes the locking member 200 to move towards the connecting part 111, so that the locking member 200 abuts against the outside of the photographic equipment 20, thereby realizing the quick and automatic locking of the photographic equipment 20. When it is necessary to remove the photographic equipment 20 from the above-mentioned disassembly and assembly mechanism 10, the unlocking member 400 can be controlled to overcome the reverse damping of the first elastic member 320, so that the unlocking member 400 rotates to the unlocking position, so that the first limiting post 421 pushes the locking member 200 to move away from the photographic equipment 20, so that the locking member 200 releases the abutment against the outside of the photographic equipment 20, thereby realizing the quick release of the locking of the photographic equipment 20.

[0040] Furthermore, the locking member 200 includes a fastening portion 210 and a blocking portion 220. The fastening portion 210 is positioned facing the connecting portion 111. When an external force rotates the unlocking member 400 to the unlocked position, the first limiting post 421 abuts against the blocking portion 220, thereby pushing the locking member 200 to move away from the photographic equipment 20, causing the fastening portion 210 to enter the connecting position. The end of the fastening portion 210 facing the photographic equipment 20 abuts against the outer side of the photographic equipment 20, thereby locking the photographic equipment 20. When the external force is released, the first elastic member 320 can push the unlocking member 400 to rotate in the opposite direction, thereby causing the first limiting post 421 to move in the opposite direction, pushing the locking member 200 to move towards the photographic equipment 20, causing the locking member 200 to abut against the outer side of the photographic equipment 20, thereby quickly releasing the locking of the photographic equipment 20.

[0041] It should be noted that the first elastic element 320 in this application can be a spring, tension spring, magnetic body, etc.

[0042] When the first elastic element 320 is a magnetic body, it should be divided into two parts with opposite magnetic properties. One part is connected to the unlocking element 400, and the other part is connected to the housing 100. When an external force is applied to rotate the unlocking element 400 toward the unlocking position, the two parts of the first elastic element 320 with opposite magnetic properties move closer to each other, thereby generating damping on the unlocking element 400 in the opposite direction to the external force. When the external force is released, the damping will automatically push the unlocking element 400 to rotate in the opposite direction, that is, push the unlocking element 400 to rotate toward the locking position, thereby achieving the effect of automatic locking.

[0043] Similarly, when the first elastic element 320 is a tension spring, during the process of applying an external force to rotate the unlocking element 400 toward the unlocking position, the first elastic element 320 is rotated and pulled, which dampens the unlocking element 400 in the opposite direction to the external force. When the external force is released, the damping will automatically push the unlocking element 400 to rotate in the opposite direction, that is, push the unlocking element 400 to rotate toward the locking position, thereby achieving the effect of automatic locking.

[0044] In one embodiment, the housing 100 also has a groove. The unlocking member 400 has a second limiting post 422 facing the groove. One end of the first elastic member 320 abuts against the second limiting post 422, and the other end abuts against a side wall of the groove. When an external force is applied to rotate the unlocking member 400 to the unlocked position, the first elastic member 320 is compressed by the unlocking member 400 and the groove, and a reverse damping is applied to the unlocking member 400. When the external force is released, the first elastic member 320 extends to its naturally unfolded state and pushes the unlocking member 400 to rotate in the opposite direction. At this time, the first elastic member 320 is a spring.

[0045] Therefore, when it is necessary to install the photographic equipment 20, the photographic equipment 20 can be partially placed in the connecting part 111. The first elastic member 320 will then extend to its naturally unfolded state, pushing the second limiting post 422 to rotate, causing the unlocking member 400 to rotate to the locked position. During this process, the first limiting post 421 pushes the blocking part 220 to move closer to the connecting part 111, which can drive the locking member 200 to move towards the connecting part 111, so that the fastening part 210 of the locking member 200 abuts against the outside of the photographic equipment 20, thereby realizing the locking of the photographic equipment 20. The camera equipment 20 can be quickly and automatically locked. When it is necessary to remove the camera equipment 20 from the above-mentioned disassembly and assembly mechanism 10, the unlocking member 400 can be controlled to overcome the elastic force of the first elastic member 320, so that the unlocking member 400 rotates to the unlocking position, and the first limiting post 421 pushes the blocking part 220 to move away from the connecting part 111. This can drive the locking member 200 to move away from the camera equipment 20, so that the fastening part 210 of the locking member 200 releases its contact with the outside of the camera equipment 20, thereby realizing the quick release of the camera equipment 20 from locking.

[0046] It should be noted that the housing 100 can be any structure such as a cuboid or cylinder. Specifically, in this embodiment, the housing 100 is cylindrical, and the photographic equipment 20 is oriented along the axis of the housing 100 (e.g., ...). Figure 2 The clip 200 is mounted on (or removed from) the connector 111 in any direction indicated by the S-arrow. The clip 200 is positioned radially along the housing 100 (e.g., in any direction indicated by the S-arrow). Figure 2 The unlocking component 400 moves in any direction indicated by the T-arrow, and moves along the circumference of the housing 100 (e.g., ...). Figure 2 , Figure 8 and Figure 9 Rotate in any direction indicated by the U-shaped arrow.

[0047] Furthermore, the fastening portion 210 can match the mounting portion 21 on the side wall of the photographic equipment 20 to improve the stability of the fastening portion 210 in fixing the photographic equipment 20. Specifically, in this embodiment, as... Figure 2 As shown, the mounting part 21 is in the shape of an equilateral triangle, while the fastening part 210 is in the shape of an inverted triangle. When the photographic equipment 20 is placed in the connecting part 111, part of the fastening part 210 is located above the mounting part 21 and abuts against the mounting part 21, which helps to improve the stability of the photographic equipment 20 during installation.

[0048] Understandably, both ends of the first elastic member 320 can be fixedly connected to the second limiting post 422 and the inner wall of the groove, respectively, to improve the stability of the connection of the first elastic member 320. Of course, one end of the first elastic member 320 can be fixedly connected to the second limiting post 422 or the inner wall of the groove, and the other end can be movably connected to the inner wall of the groove or the second limiting post 422.

[0049] In one embodiment, such as Figure 2 , Figures 12-14 As shown, the housing 100 includes an upper housing 110 and a lower housing 120. A side of the upper housing 110 facing away from the lower housing 120 is recessed to form a connecting portion 111. The side wall of the connecting portion 111 has a side hole 112 for the insertion and exit of a locking member 200. Each side hole 112 corresponds to a locking member 200, allowing each locking member 200 to enter the area of ​​the connecting portion 111 through the side hole 112. An accommodating space (not shown) is formed between the upper housing 110 and the lower housing 120 to accommodate the locking member 200, the first elastic member 320, and part of the unlocking member 400.

[0050] Therefore, the recessed connecting part 111 facing the lower shell 120 can provide a sufficiently deep installation space for the photographic equipment 20, and is conducive to improving the utilization rate of the space occupied by the shell 100, making the disassembly and assembly mechanism 10 look more aesthetically pleasing overall.

[0051] In one embodiment, such as Figure 7 As shown, the unlocking component 400 includes a rotating body 410 and an extension 420. The rotating body 410 is disposed on the outer periphery of the housing 100. The extension 420 extends into the accommodating space. Therefore, during the unlocking process, the rotating body 410 located on the outer periphery of the housing 100 can be directly controlled to rotate, thereby driving the extension 420 located in the accommodating space inside the housing 100 to rotate.

[0052] In one embodiment, such as Figures 1-7 As shown, the second limiting post 422 is provided on the side of the extension 420 facing the upper shell 110. A groove is provided on the side of the upper shell 110 facing the lower shell 120, and on the side of the extension 420 facing the locking member 200. The first elastic member 320 is located in the groove. One end of the first elastic member 320 abuts against the second limiting post 422, and the other end abuts against the side wall of the groove. Therefore, during the rotation of the unlocking member 400 relative to the upper shell 110, the second limiting post 422 also rotates relative to the groove. That is, when the unlocking member 400 rotates to the unlocked position, the first elastic member 320 is compressed by the second limiting post 422 and the groove; when the unlocking member 400 is in the locked position, the first elastic member 320 extends to its naturally unfolded state.

[0053] It should be noted that the user needs to first control the second limiting post 422 to overcome the elastic force of the first elastic member 320 and rotate it relative to the groove, so as to force the first elastic member 320 to compress. Only then can the unlocking member 400 be rotated, driving the first limiting post 421 to push the blocking part 220, thereby pushing the locking member 200 to rotate away from the connecting part 111, releasing the locking member 200 from the mounting part 21, and finally releasing the constraint of this disassembly and assembly mechanism 10 on the photographic equipment 20. Since the unlocking member 400 can be controlled to rotate relative to the housing 100 by holding the rotating body 410 located on the outer periphery of the housing 100 with one hand, the unlocking method of this application is simple and labor-saving, and the unlocking action can be completed without additional tools, which is beneficial to improving the disassembly speed and efficiency.

[0054] Furthermore, the first limiting post 421 is provided on the side of the extension 420 facing the locking member 200. The first limiting post 421 is cylindrical, so during the process of controlling the rotation of the unlocking member 400, the side of the first limiting post 421 has no sharp edges, which helps to reduce the friction between the first limiting post 421 and the blocking part 220 and avoid excessive wear of the first limiting post 421 and the blocking part 220.

[0055] Furthermore, in one embodiment, such as Figures 1-7As shown, the projected outer periphery of both the rotating body 410 and the housing 100 is circular. The circular outer periphery makes it easier for the user to hold, thus improving the user's comfort. In addition, the circular outer periphery is similar in shape to the lens of the photographic equipment 20 (both are circular), which helps to improve the aesthetics of the connection and use between the disassembly mechanism 10 and the photographic equipment 20.

[0056] In addition, such as Figure 7 As shown, the outer surface of the rotating body 410 is provided with anti-slip ridges 411 to prevent slippage when rotating the unlocking part 400, thereby improving stability and convenience of use. In addition, the length direction of the anti-slip ridges 411 should be set at an angle to the rotation direction of the unlocking part 400, preferably perpendicular, to improve the anti-slip effect of the anti-slip ridges 411.

[0057] In one embodiment, such as Figure 12 As shown, the connecting part 111 has a through hole 113. The connecting part 111 also includes a second elastic member 330 and a top post 114. The top post 114 is movably inserted through the through hole 113. The two opposite ends of the second elastic member 330 are connected to the lower shell 120 and the top post 114, respectively. The second elastic member 330 is used to push the top post 114 through the through hole 113 to abut against the photographic equipment 20. Therefore, during the unlocking process, when the fastening part 210 of the clip 200 is released from abutment with the mounting part 21 of the photographic equipment 20, the second elastic member 330 pushes the top post 114 and the photographic equipment 20 to move, so as to push the photographic equipment 20 outward away from the space where the connecting part 111 is located, facilitating disassembly.

[0058] Furthermore, such as Figure 2 and Figure 5 As shown, the lower shell 120 is provided with a third limiting post 121. The third limiting post 121 is aligned with the through hole 113 and passes through the second elastic member 330. In this embodiment, the second elastic member 330 is a spring, so the third limiting post 121 passing through the second elastic member 330 can limit the left and right swaying of the second elastic member 330 and improve the installation stability of the second elastic member 330.

[0059] In one embodiment, such as Figure 1-14 As shown, the disassembly and assembly mechanism 10 also includes a third elastic member 310. The third elastic member 310 abuts against the end of the locking member 200 opposite to the connecting portion 111. Specifically, when the unlocking member 400 rotates to the unlocked position, the first limiting post 421 abuts against the blocking portion 220 to compress the third elastic member 310. When the unlocking member 400 is in the locked position, the first limiting post 421 releases contact with the blocking portion 220, and the third elastic member 310 extends to its naturally unfolded state.

[0060] Therefore, when the unlocking member 400 is in the locked position, the third elastic member 310 can increase the holding force between the card 200 and the photographic equipment 20, thereby improving the stability of the connection of the photographic equipment 20.

[0061] It should be noted that, since the first elastic element 320 has the ability to restore its natural unfolded state, when the external force applied by the user rotating the main body 410 decreases or disappears, the first elastic element 320 can automatically push the second limiting post 422 to rotate in the opposite direction (opposite to the direction of unlocking), thereby causing the extension 420, the rotating main body 410, and the unlocking member 400 to rotate in the opposite direction, so that the unlocking member 400 rotates to the locked position. At this time, the first limiting post 421 also releases its contact with the blocking part 220, and the third elastic element 310 can push the locking member 200 into the connecting part 111, which can lock with the mounting part 21 of the photographic equipment 20 located in the connecting part 111, thereby realizing the "automatic locking" of the photographic equipment 20. Therefore, after the user inserts the photographic equipment 20 into the connecting part 111, the disassembly and assembly mechanism 10 can automatically lock the photographic equipment 20 under the elastic force of the first elastic element 320 and the third elastic element 310. The locking method is simple and labor-saving, and the locking action can be completed without additional tools and operations, which helps to improve the installation speed and efficiency.

[0062] It should also be noted that, such as Figure 2 As shown, with the camera equipment 20 facing downwards (to face the camera)... Figure 2 During the process of approaching the connecting part 111 (with the orientations of up, down, left, and right), the lower left side of the mounting part 21 first abuts against the upper right side of the fastening part 210, pushing the clip 200 to move to the left against the elastic force of the third elastic member 310. This allows the clip 200 to avoid the photographic equipment 20, facilitating the photographic equipment 20 to approach and fit against the connecting part 111. After the photographic equipment 20 fits against the connecting part 111, the pushing force of the mounting part 21 on the fastening part 210 disappears, and the third elastic member 310 extends towards its naturally unfolded state, pushing the clip 200 to the right until the right side of the clip 200 abuts against the side of the photographic equipment 20. This completes the installation of the photographic equipment 20. In this state, the lower side of the clip 200 is above the upper side of the mounting part 21, preventing the photographic equipment 20 from moving upwards and further improving the installation stability of the photographic equipment 20.

[0063] Furthermore, such as Figure 2 , Figure 5 , Figure 10 and Figure 11As shown, the end of the clip 200 opposite to the connecting portion 111 has a mounting groove 230, into which one end of the third elastic member 310 can extend. This arrangement improves the stability of the contact between the third elastic member 310 and the clip 200. Furthermore, the end of the third elastic member 310 connected to the housing 100 can be either fixedly connected or movably connected. When one end of the third elastic member 310 is fixedly connected to the housing 100 and the other end extends into the mounting groove 230, the installation and operational stability of the third elastic member 310 are effectively improved.

[0064] In one embodiment, such as Figures 1-6 As shown, the number of locking pieces 200, the third elastic member 310, and the first limiting post 421 are the same, and there are at least two of them. At least two locking pieces 200 are arranged at equal intervals circumferentially with the connecting portion 111 as the center. In this application, the third elastic member 310 is a spring.

[0065] It should be noted that when there are two cards 200, the two cards 200 are set opposite each other, that is, the moving directions of the two cards 200 are on the same straight line, and the angle between the moving directions of the two cards 200 is 180°; when there are three cards 200, the angle between the moving directions of the three cards 200 is 120°; when there are four cards 200, the four cards 200 are set opposite each other in pairs, and the lines connecting the two pairs of opposite cards 200 are perpendicular to each other, that is, the angle between the moving directions of the adjacent cards 200 is 90°, and so on when there are more than four cards 200.

[0066] Specifically, in this embodiment, there are four locking pieces 200, four third elastic members 310, and four first limiting posts 421. The four locking pieces 200 can restrict the outer side of the photographic equipment 20 in four directions: front, back, left, and right, which helps to improve the installation stability of the photographic equipment 20.

[0067] In one embodiment, such as Figure 8 and Figure 9 As shown, the blocking portion 220 extends towards the first limiting post 421. The sidewall of the blocking portion 220 that abuts against the first limiting post 421 is set at an angle α with the extension direction of the third elastic member 310 (i.e., the radial direction of the housing 100), and this angle α is an acute angle. The tip of the angle α faces the third elastic member 310.

[0068] Understandably, when the unlocking member 400 rotates by the same angle, the smaller the included angle α, the greater the distance that the first limiting post 421 pushes the blocking part 220 to move, that is, the greater the distance that pushes the locking member 200 to move away from the connecting part 111, and the greater the distance that the third elastic member 310 is compressed. The specific angle α can be adjusted according to actual needs and is not limited here.

[0069] It should be noted that, as Figure 8 As shown, when the unlocking member 400 is in the locked position, the first limiting post 421 does not abut against the blocking part 220. At this time, the third elastic member 310 pushes the locking member 200 to the right to abut against the side wall of the photographic equipment 20. Figure 9 As shown, during the counterclockwise rotation of the unlocking component 400, the first limiting post 421 gradually rotates to abut against the blocking part 220. When the unlocking component 400 rotates clockwise to the unlocking position, the first limiting post 421 will push the locking component 200 to overcome the elastic force of the third elastic component 310 and move to the left, releasing the locking component 200 from the constraint of the side wall of the photographic equipment 20.

[0070] Understandably, the sidewall where the blocking part 220 abuts against the first limiting post 421 can be a flat surface or a curved surface. When the sidewall where the blocking part 220 abuts against the first limiting post 421 is a curved surface, it should be ensured that when the unlocking member 400 rotates to the unlocking position, the first limiting post 421 can push the locking member 200 to the engaging part 210 and the mounting part 21 to release the restriction.

[0071] To facilitate understanding, the positional relationships of the various components of the disassembly and assembly mechanism 10 in this application under different usage states are further explained below:

[0072] like Figures 1-14 As shown, the disassembly and assembly mechanism 10 in this application is in its natural state. At this time, the third elastic member 310 extends to its natural extension state, with its two ends abutting against the inner sidewall of the upper shell 110 and the locking member 200, respectively, so that the fastening part 210 extends into the space where the connecting part 111 is located; the first limiting post 421 and the blocking part 220 are not in the abutting state; the first elastic member 320 extends to its natural unfolding state, with its two ends abutting against the inner sidewall of the groove and the second limiting post 422, respectively, so that the unlocking member 400 is in the locked position; the second elastic member 330 extends to its natural unfolding state, with its two ends abutting against the lower shell 120 and the top post 114, respectively, so that the top post 114 passes through the through hole 113 and enters the space where the connecting part 111 is located.

[0073] As the user inserts the photographic equipment 20 to be installed into the connecting part 111, the user rotates the unlocking member 400 to the unlocked position, causing the second limiting post 422 and the side wall of the groove to compress the first elastic member 320, so that the first limiting post 421 abuts against the blocking part 220, and causes the locking member 200 to move away from the connecting part 111, so that the space at the connecting part 111 is completely cleared for the photographic equipment 20 to be placed. The photographic equipment 20 presses down on the top post 114 and gradually compresses the second elastic member 330. When the user installs the photographic equipment 20 in place, the user releases the unlocking member 400, and the first elastic member 320 pushes the second limiting post to rotate in the opposite direction. The unlocking member 400 rotates in the opposite direction, the constraint between the first limiting post 421 and the blocking part 220 is released, the third elastic member 310 pushes the locking member 200 part to extend out of the side hole 112, the fastening part 210 locks with the mounting part 21, and the second elastic member 330 is compressed to its minimum length.

[0074] During the process of removing the photographic equipment 20 from the disassembly and assembly mechanism 10, the user first rotates the unlocking component 400 to the unlocking position, which causes the second limiting post 422 and the side wall of the groove to compress the first elastic member 320, so that the first limiting post 421 abuts against the blocking part 220, and causes the locking component 200 to move towards the connecting part 111, so as to completely make room at the connecting part 111. The second elastic member 330 pushes the top post 114 and the photographic equipment 20 upward, and the user can take out the photographic equipment 20. After the user releases his hand, the unlocking component 400 gradually and automatically returns to the locked position, and the disassembly and assembly mechanism 10 finally returns to its natural state.
