[0045] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described and do not have any sequential or technical meaning. And as used in this application, "connection" and "coupling", unless otherwise specified, both include direct and indirect connection (coupling).
[0046] Please refer to Figures 1 - 3 , the present utility model provides an expansion bracket 20 for detachably connecting and fixing to the mounting portion 11 on the outer side of the storage platform 10, so that the entire expansion bracket 20 can be stably fixed on the outer side of the storage platform 10. Please refer to Figures 4 - 7 , the expansion bracket 20 includes an object placement member 23, a first clamping member 21, and a second clamping member 22. The object placement member 23 has an object placement portion 231 for placing objects. Both the first clamping member 21 and the second clamping member 22 are connected to the object placement member 23, and the first clamping member 21 can slide and adjust relative to the second clamping member 22 along a first direction; when the first clamping member 21 is in a first position relative to the second clamping member 22, the first clamping member 21 is used to clamp the storage platform 10 with the second clamping member 22, and the first clamping member 21 can slide from the first position to a second position relative to the second clamping member 22 to release the storage platform 10.
[0047] According to the above-mentioned expansion bracket 20, the storage platform 10 is clamped by the first clamping member 21 and the second clamping member 22 with relative adjustable positions to initially position the entire expansion bracket 20 on the storage platform 10, and then the expansion bracket 20 is detachably fixed to the mounting portion 11 of the storage platform 10, thereby stably installing the expansion bracket 20 on the storage platform 10. The object placement portion 231 of the object placement member 23 of the expansion bracket 20 can be used to place or hang objects, which can meet the needs of placing and / or hanging objects, and thus can expand the storage capacity of the storage platform 10 and facilitate the user to transfer and use objects.
[0048] This application does not limit the specific structure of the object placement portion 231. For example, in some embodiments, the object placement portion 231 can be a flat structure for placing objects or a box structure with a receiving cavity. In some embodiments, please refer to Figure 4, the storage part 231 can also be a hook structure. When the expansion bracket 20 is applied to the field of photography, it can facilitate the user to transfer shooting accessories and achieve the effect of hanging objects such as photography accessories, which can meet the needs of hanging some photography accessories for standby and also meet the needs of additional hanging. In some embodiments, the storage part 231 can also have the functions of placing objects and hooking objects at the same time.
[0049] It should be noted that when the same expansion bracket 20 is installed on different storage platforms 10, the first position may change, which is specifically related to factors such as the structure and size of the storage platform 10. Similarly, the second position can be any position where the second clamping member 22 can be separated from the storage platform 10. However, it should be noted that while meeting the requirement of being able to be separated from the storage platform 10, it is also necessary to enable the expansion bracket 20 to meet the requirement of being unloaded and removed from the state of being loaded on the storage platform 10 at the second position. In different embodiments, the second position can be any position between the first position and the limit position including the limit position. The limit position is the limit position where the first clamping member 21 can slide relative to the second clamping member 22 when the storage platform 10 is released. And in some embodiments, the expansion bracket 20 may have the function of automatically resetting without external force. At this time, the first position of the first clamping member 21 may be the same as or different from the initial position of the first clamping member 21, and both can be adjusted adaptively according to actual needs. The present application does not make a limitation.
[0050] The present application does not limit the actual solution for the detachable fixation of the expansion bracket 20 and the installation part 11, and it can be any feasible solution. For example, in some embodiments, the whole expansion bracket 20 can be directly disassembled and assembled with the installation part 11 through a threaded fastener 60, or it can also be achieved by a magnetic fixation method.
[0051] In addition, the above-mentioned "the first clamping member 21 can slide and adjust relative to the second clamping member 22 along the first direction" means that the first clamping member 21 and the second clamping member 22 or the placed object 23 are in sliding fit, but not only in sliding fit, so as to have the function of adjustable relative position, so that when the first clamping member 21 is in different first positions relative to the second clamping member 22, it can clamp the storage platform 10 of the corresponding size, that is, the expansion bracket 20 can be installed on the storage platform 10 within a certain thickness range. There are many specific solutions that can achieve the sliding adjustment of the first clamping member 21 relative to the second clamping member 22 along the first direction. The present application does not make a limitation, and those skilled in the art can adopt any feasible solution.
[0052] In some embodiments, the first clamping member 21 and the second clamping member 22 can be slidably engaged with the object placement member 23 simultaneously. The first clamping member 21 and the second clamping member 22 can be synchronously driven to move away from or close to each other in the first direction, so as to realize that the first clamping member 21 can slide and adjust relative to the second clamping member 22 in the first direction.
[0053] In some embodiments, please refer to Figure 4 , in order to simplify the structure, control the cost and facilitate production and manufacturing, the object placement member 23 and the second clamping member 22 can be fixedly connected. The fixed connection includes but is not limited to detachable connection, integral molding and welding. Thus, the object placement member 23 and the second clamping member 22 are connected as a whole, and the first clamping member 21 slides and adjusts relative to the whole of the second clamping member 22 and the object placement member 23 in the first direction. Since the position of the second clamping member 22 is fixed relative to the object placement member 23, the second clamping member 22 can be used as the positioning basis for the mutual installation and cooperation between the expansion bracket 20 and the object placement platform 10, which is beneficial to improving the installation convenience, stability and accuracy of the expansion bracket 20.
[0054] In some embodiments, looking only at the structure of the expansion bracket 20, for the sliding adjustment of the first clamping member 21 relative to the second clamping member 22, the user needs to keep applying an external force to move the first clamping member 21 from the initial position to the second position, or to position the first clamping member 21 at a certain position between the initial position and the second position. When the external force is removed, the first clamping member 21 will reset, which is not convenient for the user to operate. Therefore, in some embodiments, a lockable function of the first clamping member 21 and the second clamping member 22 in the second position state can be added to the above solution. In some embodiments, a pin-type locking technical solution can be adopted. For example, pin holes are respectively provided on the first clamping member 21 and the second clamping member 22, and the first clamping member 21 and the second clamping member 22 are locked by inserting a pin into the pin holes that are opposite to each other in the second position; or pin holes are respectively provided on the first clamping member 21 and the object placement member 23, and the first clamping member 21 and the second clamping member 22 are locked by inserting a pin into the pin holes that are opposite to each other in the second position.
[0055] In some embodiments, in order to further improve the operability of locking the first clamping member 21 and the second clamping member 22 in the second position, please refer to Figures 6 - 11 , the expansion bracket 20 further includes a locking member 24. The first clamping member 21 has an adjustment groove 211. The locking member 24 is arranged in the adjustment groove 211, and the adjustment groove 211 can slide relative to the locking member 24 in the first direction; the locking member 24 is used to lock the relative positions of the first clamping member 21 and the second clamping member 22 when the first clamping member 21 is in the second position.
[0056] Since the second clamping member 22 is fixedly connected to the object placing member 23, the locking member 24 can be positioned and installed on the second clamping member 22 and / or the object placing member 23. The locking member 24 can directly lock the first clamping member 21 and the second clamping member 22, and can also indirectly lock the first clamping member 21 and the second clamping member 22 by locking the relative positions of the first clamping member 21 and the object placing member 23. The locking member 24 can also connect the object placing member 23, the first clamping member 21 and the second clamping member 22 simultaneously. For example, in some embodiments, the locking member 24 can be a bolt, and through holes for installing and fixing the bolt are provided on the object placing member 23 and / or the second clamping member 22, and the relative positions of the first clamping member 21 and the second clamping member 22 are directly or indirectly locked through the screw rod and the nut.
[0057] In some embodiments, please refer to Figure 7 , Figure 9 , Figure 10 and Figure 14 , the locking member 24 includes a first cylinder 241 and a second cylinder 242 connected along the axis. The size of the first cylinder 241 is larger than that of the second cylinder 242. The adjustment groove 211 includes a first groove body 212 and a second groove body 213 communicating along the first direction. The width dimension of the second groove body 213 perpendicular to the first direction is smaller than the width dimension of the first groove body 212 perpendicular to the first direction. The first groove body 212 matches the first cylinder 241 and is used for receiving the first cylinder 241. During the process of the first clamping member 21 moving to the second position, the second cylinder 242 is in sliding fit with the second groove body 213. When the first clamping member 21 is located at the second position, the locking member 24 is located in the first groove body 212, and the first cylinder 241 can move into the first groove body 212 to lock the relative positions of the first clamping member 21 and the second clamping member 22. In this technical solution, the second clamping member 22 is fixedly connected to the object placing member 23. By providing a hole for installing the locking member 24 on the object placing member 23 and / or the second clamping member 22, the locking member 24 can only move axially relative to the object placing member 23, and the first cylinder 241 can be selectively moved axially into or out of the first groove body 212 manually or automatically.
[0058] In some embodiments, in order to install the locking member 24 and prevent the locking member 24 from detaching from the expansion bracket 20, please refer to Figures 6 - 7 , Figures 13 - 14The storage piece 23 is connected and fixed to the second clamping piece 22, the first clamping piece 21 is clamped between the storage piece 23 and the second clamping piece 22, and one end of the first clamping piece 21 extends out to cooperate with the first clamping piece 21 to clamp the storage platform 10, that is, the second clamping piece 22, the first clamping piece 21 and the storage piece 23 form a sandwich assembly connection. The second clamping member 22 has a mounting through hole 222 for positioning the second column 242, and the second column 242 can slidably cooperate with the mounting through hole 222, and the end of the second column 242 away from the first column 241 extends out of the mounting through hole 222; the side of the storage member 23 facing the first clamping member 21 is provided with a accommodating blind groove 232 matching the first column 241, when the first clamping member 21 is in the second position, the accommodating blind groove 232 is opposite to the first slot 212, and the first column 241 can be moved axially into the first slot 212, thereby locking the first clamping member 21 and the second clamping member 22, at this time The expansion bracket 20 is locked in the state to be installed, and the expansion bracket 20 is initially installed on the storage platform 10. At this time, it is manually unlocked or automatically unlocked, so that the first column 241 moves axially to disengage from the first slot 212 and return to the accommodating blind slot 232. Without applying external force to the first clamping member 21, the first clamping member 21 can move to the initial position relative to the second clamping member 22 until it contacts the storage platform 10 and reaches the first position. The first clamping member 21 and the second clamping member 22 can work together. After the expansion bracket 20 is connected and fixed to the mounting portion 11, the overall installation of the expansion bracket 20 is completed.
[0059] It should be noted that, with respect to the above-mentioned “the end of the second column 242 away from the first column 241 extends out of the mounting through hole 222”, if the extended end of the second column 242 needs to be toward the outer side of the storage platform 10, then when designing the length of the second column 242, it is necessary to consider that the second column 242 will not interfere with the connection and cooperation with the outer side of the storage platform 10.
[0060] In some embodiments, to achieve automatic locking and automatic unlocking after installation on the storage platform 10, please refer to Figure 11 , Figure 7 and Figure 14, one end of the second cylinder 242 that extends out faces the outer side of the storage platform 10 and is used to abut against the side of the storage platform 10. The expansion bracket 20 further includes a first elastic member 25. The first elastic member 25 is installed in the receiving blind slot 232. One end of the first elastic member 25 is connected to or abuts against the placed object 23, and the other end is connected to or abuts against the locking member 24. The end face of the second clamping member 22 close to the first clamping member 21 is used to limit the first cylinder 241, or a limiting step 2121 for axially limiting the first cylinder 241 along the locking member 24 is provided in the first groove 212, so as to clamp the first cylinder 241 between the second clamping member 22 and the placed object 23. When the first clamping member 21 is adjusted to the second position by an external force, under the action of the first elastic member 25, the locking member 24 is driven to move to the side away from the placed object 23 until the first cylinder 241 is clamped in the first groove 212 of the first clamping member 21 to complete the locking. After the user removes the external force, the first clamping member 21 can still maintain the locked state with the second clamping member 22. When the locking member 24 is manually pressed until the first cylinder 241 moves into the receiving blind slot 232 and completely disengages from the first groove 212, or when the expansion bracket 20 is installed on the storage platform 10, the locking member 24 is pushed back by the side of the storage platform 10 until the first cylinder 241 moves into the receiving blind slot 232 and completely disengages from the first groove 212 to achieve unlocking. The first clamping member 21 can automatically adjust to the first position and cooperate with the second clamping member 22 to clamp the storage platform 10. The size of the second groove 213 is smaller than the size of the first cylinder 241. Therefore, after unlocking, in the axial direction of the locking member 24, the end face of the first clamping member 21 facing the placed object 23 can limit the movement of the first cylinder 241, enabling the first clamping member 21 and the second clamping member 22 to move relative to each other smoothly.
[0061] In some embodiments, please refer to Figure 7 , Figure 9 , Figure 10 and Figures 14 - 15 , in order to install the first elastic member 25 so that the first elastic member 25 can generate sufficient elastic force to push the locking member 24 to move, and at the same time effectively control the overall size of the expansion bracket 20, the locking member 24 has a first blind hole. The opening of the first blind hole faces the side where the first cylinder 241 is located. The first elastic member 25 is installed in the first blind hole, and one end of the first elastic member 25 extends out of the first blind hole and is used to abut against the bottom of the receiving blind slot 232.
[0062] In some embodiments, in order to enable the relative adjustment of the position of the first clamping member 21, please refer to Figures 9 - 11, the object placement member 23 is fixedly connected to the second clamping member 22. The extension bracket 20 further includes a second elastic member 26. Along the first direction, one end of the second elastic member 26 is connected to the object placement member 23 or the second clamping member 22, and the other end is connected to the first clamping member 21. The second elastic member 26 is used to drive the first clamping member 21 to reset in the state without external force, and the reset means returning to the above-mentioned initial position.
[0063] In some embodiments, the object placement member 23 is detachably connected to the second clamping member 22. The first clamping member 21 is clamped between the object placement member 23 and the second clamping member 22. The first clamping member 21 and the object placement member 23 are slidably connected through a sliding groove 214 and a guiding post 233. One of the sliding groove 214 and the guiding post 233 is provided on the first clamping member 21, and the other is provided on the object placement member 23. The second elastic member 26 connects the object placement member 23 and the first clamping member 21. In some embodiments, please refer to Figure 9 , the sliding groove 214 is provided on the first clamping member 21, and the guiding post 233 is integrally formed on the object placement member 23.
[0064] In some embodiments, in order to facilitate driving the first clamping member 21 to slide relative to the second clamping member 22 to adjust the relative position, the extension bracket 20 further includes a driving member 27. The driving member 27 is installed on the object placement member 23 or the second clamping member 22, and the driving member 27 is in transmission connection with the first clamping member 21 to drive the first clamping member 21 to move from the first position to the second position. The present application does not limit the specific scheme of the driving member 27. For example, it can be a lever, a push switch, etc., as long as it can realize the function of driving the first clamping member 21 to move from the first position to the second position.
[0065] In some embodiments, please refer to Figure 9 and Figure 10 , the driving member 27 includes a button 271 and a third elastic member 272. The button 271 is installed on the object placement member 23 with a limit. The button 271 and the first clamping member 21 have mutually cooperating pushing inclined surfaces to convert the movement of the button 271 into the movement of the first clamping member 21 along the first direction through the pushing inclined surfaces, that is, driving the first clamping member 21 to move along the first direction by pressing the button 271. One end of the third elastic member 272 acts on the button 271, and the other end acts on the object placement member 23 to drive the button 271 to reset.
[0066] Based on the same inventive concept, the present application also provides a storage device 100, including a storage platform 10 and the extension bracket 20 in the above embodiments, wherein: the outer side surface of the storage platform 10 has a mounting portion 11; the extension bracket 20 is detachably connected and fixed to the mounting portion 11, so that the whole extension bracket 20 can be stably fixed on the outer side surface of the storage platform 10.
[0067] In some embodiments, the first clamping member 21 and the second clamping member 22 may only have the function of clamping the storage platform 10, and then achieve stable installation through a detachable connection with the mounting portion 11. In some embodiments, the first clamping member 21 and the second clamping member 22 may also cooperate with the storage platform 10 to achieve positioning in other directions.
[0068] For example, in some embodiments, please refer to Figure 4 and Figure 12 The second clamping member 22 has a second hook portion 221 extending to a side away from the storage member 23. The storage platform 10 has an open storage cavity 12. The mounting portion 11 also includes a side cavity wall of the storage cavity 12, and the side cavity wall of the storage cavity 12 constitutes the side wall 13 of the storage platform 10. When the expansion bracket 20 is fixed to the storage platform 10, the side cavity wall, i.e., the side wall 13, extends into the second hook portion 221 to be hung with the second hook portion 221. In other words, when the expansion bracket 20 is installed, the storage platform 10 is placed with the storage cavity 12 facing upward, so that the opening of the second hook portion 221 faces the bottom of the storage cavity 12, and the expansion bracket 20 is moved in the vertical direction toward the storage platform 10, and the side wall 13 of the storage platform 10 is inserted into the opening of the second hook portion 221, so that the storage portion 231 can be hooked with the side wall 13 of the storage platform 10, simplifying the hooking and matching scheme of the storage portion 231 and the storage platform 10. It should be noted that when the expansion bracket 20 is installed and fixed on the storage platform 10, the opening of the second hook portion 221 faces vertically downward.
[0069] In some embodiments, please refer to Figure 4 and Figure 12 The first clamping member 21 has a first hook portion 215 extending toward a side away from the storage member 23, and the opening of the second hook portion 221 is aligned with the opening of the first hook portion 215 in the first direction. The mounting portion 11 also includes a clamping slot 111, the opening of the clamping slot 111 at least faces the first hook portion 215, so that the first hook portion 215 can extend into the clamping slot 111 or detach from the clamping slot 111 along the first direction; that is, the first clamping member 21 moves to a first position in the first direction toward the second clamping member 22, and the first hook portion 215 can be clamped in the clamping slot 111, and the first clamping member 21 moves away from the second clamping member 22 in the first direction to leave the first position, then the first hook portion 215 detaches from the clamping slot 111, and then expands to be stably attached to the outer side surface of the storage platform 10 through the second hook portion 221 and the first hook portion 215, and the clamping slot 111 can at least limit the displacement of the first hook portion 215 toward or away from the outer side surface of the storage platform 10.
[0070] It should be noted that in some embodiments, the storage platform 10 may be a lidless structure. In other embodiments, the storage platform 10 may also be a lidded structure. When using the hook, the lid needs to be removed, or there is a structure on the lid corresponding to avoid the expansion bracket 20. When the hook is not in use and the storage platform 10 needs to be transferred over a long distance, the lid is installed to encapsulate the storage cavity 12, thereby protecting the internal photographic accessories.
[0071] In some embodiments, in order to make the connection between the expansion bracket 20 and the storage platform 10 more stable and effective, please refer to Figure 2 and Figure 3 , the installation part 11 further includes a first magnetic part 112. A second magnetic part is provided at the corresponding position of the expansion bracket 20.

It should be noted that the multiple storage platforms 10 refer to two or more storage platforms 10.
[0078] In some embodiments, please refer to Figure 1 and Figure 12 , each of the multiple storage platforms 10 has a storage cavity 12, and the multiple storage platforms 10 can be connected to each other, thereby sealing the storage cavity 12 for long-distance transportation. Please refer to Figure 20 , when transporting, the expansion bracket 20 is removed. When in use, after the storage platform 10 is opened, at least one expansion bracket 20 can be installed according to needs, which can meet the need for some photographic accessories to be hung for standby, and can also increase the storage capacity of the storage platform 10.
[0079] In some embodiments, please refer to Figures 1 - 3, in order to take into account the external structure of the storage platform 10, a recess 141 for accommodating the fixing plate 15 is provided on the platform body 14.

[0082] In summary, the assembly principle of the expansion bracket 20 and the storage platform 10 disclosed in the present utility model is as follows:
[0083] The locking member 24 is installed on the second clamping member 22. The button 271 is elastically connected to the placing member 23 through the third elastic member 272. When the button 271 is pressed, the button 271 can drive the first clamping member 21 to move relative to the locking member 24 and the second clamping member 22 in the first direction until the first clamping member 21 moves to the second position. At this time, the first groove 212 also moves to align with the first column 241 of the locking member 24 and the receiving blind groove 232 on the placing member 23. Under the action of the first elastic member 25, the locking member 24 moves along its axial direction, and the first column 241 moves away from the placing member 23 and enters the first groove 212, thereby locking the first clamping member 21 and the second clamping member 22, so that the first clamping member 21 is kept in the state to be installed. At this time, the second column 242 also protrudes relatively more outwards. Please refer to Figures 12 - 16 . Specifically, from the perspective of Figure 14 , the first direction is generally the vertical direction.
[0084] Then, the user can correspondingly hold the first holding member 21 and the second holding member 22 on the side wall 13 of the placement platform 10. At this time, the side wall 13 of the placement platform 10 can press the second cylinder 242, so that the first cylinder 241 moves from the first groove 212 towards the receiving blind groove 232 until it completely disengages from the first groove 212. At this time, the locking member 24 no longer has a limiting effect on the first holding member 21, and the first holding member 21 can reset and move towards the direction close to the second holding member 22. Please refer to Figures 4 - 7 . When the first holding member 21 moves to the first position, the first holding member 21 and the second holding member 22 are synchronously clamped on the placement platform 10.
[0085] The extension bracket 20 can be stably installed on the placement platform 10. When applied to the photography industry, the placement portion 231 of the placement member 23 of the extension bracket 20 can be used to hook photographic accessories, which can meet the needs of hanging some photographic accessories for standby and the needs of additional hanging objects, can expand the placement capacity of the placement platform 10, and is convenient for the user to transfer and use shooting accessories.
