[0044] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application clearer, the following further details this application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0045] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0046] It should be understood that the orientation or positional relationship indicated by terms such as "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0047] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically defined.

[0048] The "auxiliary device" mentioned in the embodiments of the present application may include at least one of a lamp, a reflector, and a magnifying glass. In addition, the lamp may include one or more lamps. The plurality of lamps may emit the same light color, or the plurality of lamps may emit different light colors. The reflector may include one or more reflectors. The plurality of reflectors may be of the same type or different types. The magnifying glass may be one or more magnifying glasses, and the magnification factors of the plurality of magnifying glasses may be the same or different.

[0049] Please refer to Figure 1 and Figure 2 , and now the expansion bracket 1 provided by the embodiments of the present application will be described. The expansion bracket 1 includes a mounting arm 10, a fixing component 11, and a connecting seat 12. The fixing component 11 is detachably mounted on the mounting arm 10, and the mounting arm 10 is axially available for mounting a plurality of fixing components 11. The connecting seat 12 is used to connect with the auxiliary device 1000, and the connecting seat 12 is connected to the fixing component 11.

[0050] By connecting the connecting seat 12 with the auxiliary device 1000 and fixing the connecting seat 12 on the mounting arm 10 through the fixing component 11, the fixed installation of the auxiliary device 1000 and the mounting arm 10 is realized. Moreover, the mounting arm 10 is available for mounting multiple groups of fixing components 11. When multiple auxiliary devices 1000 need to be used in cooperation, multiple connecting seats 12 can be mounted on the mounting arm 10 through multiple groups of fixing components 11 to realize the synchronous use of multiple auxiliary devices 1000. When only one auxiliary device 1000 needs to be used, the redundant connecting seats 12 can also be removed from the mounting arm 10 through the detachable fixing components 11, which has better practicability and controllability.

[0051] For example, when the auxiliary device 1000 includes a plurality of lamps that emit different light colors, the plurality of lamps are respectively connected to the plurality of connection seats 12, and the plurality of connection seats 12 are installed on the mounting arm 10 through the corresponding fixing components 11, so as to form a set of lamp groups that can emit different light colors, providing colorful background lights for the shooting scene.

[0052] For another example, when the auxiliary device 1000 includes a lamp and a reflector, the lamp and the reflector are respectively connected to the connection seat 12, and the connection seat 12 is installed on the mounting arm 10 through the corresponding fixing component 11, so as to form a combined structure of the lamp and the reflector to adjust the light effect of the shooting scene.

[0053] Compared with the prior art, the expansion bracket 1 provided by the embodiment of the present application can flexibly install different numbers of connection seats 12 on the mounting arm 10 according to actual needs, so as to realize the synchronous use of one or more auxiliary devices 1000, improving the practicability of the expansion bracket 1.

[0054] In another embodiment of the present application, please continue to refer to Figure 1 and Figure 2 , the number of the fixing components 11 corresponds to the number of the connection seats 12, and each group of fixing components 11 is used to fixedly install each connection seat 12 on the mounting arm 10. Thus, each connection seat 12 can be separately disassembled and assembled on the mounting arm 10, and further each auxiliary device 1000 can be separately disassembled and assembled on the mounting arm 10, which is more flexible in use.

[0055] In another embodiment of the present application, please continue to refer to Figure 1 and Figure 2 , multiple groups of fixing components 11 can be arranged at intervals along the axial direction of the mounting arm 10.

[0056] The mounting arm 10 is a cylindrical structure, and the connection seat 12 on each group of fixing components 11 can be located on any side of the mounting arm 10. That is, in the circumferential direction of the mounting arm 10, each connection seat 12 can be located in any orientation by adjusting the installation position of the fixing component 11.

[0057] Specifically, in another embodiment of the present application, please refer to Figures 2 to 4, the fixing component 11 includes a fixing base 110, a buckling plate 111 and a buckling component 112. The fixing base 110 and the buckling plate 111 are cooperated to sleeved on the side circumference of the mounting arm 10. A sleeve notch 1100 is provided on one side of the fixing base 110. The buckling plate 111 is arranged at the sleeve notch 1100 for closing the sleeve notch 1100. One end of the buckling plate 111 is rotatably connected to the fixing base 110, and the other end of the buckling plate 111 is buckled with the fixing base 110 through the buckling component 112. During disassembly and assembly, the sleeve notch 1100 is closed by rotating the buckling plate 111, so that the fixing component 11 can be removed from the mounting arm 10 or the fixing component 11 can be sleeved tightly on the mounting arm 10.

[0058] By using the cooperation of the fixing base 110 and the buckling plate 111 to sleeve on the side circumference of the mounting arm 10, and then realizing the fixed installation with the mounting arm 10 through the buckling component 112, each connecting seat 12 can be fixedly installed at any height position of the mounting arm 10, so that the installation height of the auxiliary device 1000 can be adjusted arbitrarily, further improving the practicability and controllability.

[0059] In another embodiment of the present application, please refer to Figures 3 to 5 , the buckling component 112 includes a buckling hook 1120, a buckling body 1121 and an elastic buckling unit 1122. The buckling hook 1120 is arranged on the buckling plate 111. The buckling body 1121 is movably connected to the side wall of the fixing base 110 adjacent to the sleeve notch 1100. When the buckling plate 111 closes the sleeve notch 1100, the buckling body 1121 can move along the first direction and hook with the buckling hook 1120. The elastic buckling unit 1122 is used to buckle the buckling body 1121 and the buckling hook 1120 tightly.

[0060] When the buckling plate 111 is rotated to close the sleeve notch 1100, since the buckling body 1121 is movably connected to the fixing base 110, at this time, the position of the buckling body 1121 is adjusted to realize the hooking cooperation with the buckling hook 1120. At the same time, the elastic buckling unit 1122 is used to buckle the buckling body 1121 and the buckling hook 1120 tightly, which can prevent the buckling body 1121 from moving and easily disengaging from the buckling hook 1120, ensuring that the fixing component 11 can be sleeved tightly on the mounting arm 10.

[0061] The buckling hook 1120 here is equivalent to the structure of a hook in daily life.

[0062] In another embodiment of the present application, please continue to refer to Figures 3 to 5 , the buckling body 1121 includes a U-shaped block 210. The two sides of the U-shaped block 210 are respectively a baffle side 2100 and a notch side 2101. The baffle side 2100 is the side close to the buckling hook 1120. A buckling groove 212 is provided on the baffle side 2100. The hook end of the buckling hook 1120 is clamped into the buckling groove 212, so as to improve the reliability of the hooking cooperation between the buckling hook 1120 and the buckling body 1121.

[0063] In another embodiment of the present application, please refer to Figure 5 and Figure 6 , the buckle assembly 112 includes a mounting block 1123. The mounting block 1123 is provided on the side wall of the fixed seat 110 adjacent to the socket opening 1100. The mounting block 1123 has two mounting plates 230 arranged side by side at intervals. Slide holes 2300 are formed in both mounting plates 230. The buckle body 1121 includes a U-shaped block 210 and a connecting rod 211. The U-shaped block 210 is sleeved outside the two mounting plates 230. The two ends of the connecting rod 211 are respectively movably inserted through the corresponding slide holes 2300 and connected to the U-shaped block 210. The connecting rod 211 can move in the slide holes 2300 along a first direction.

[0064] Specifically, the mounting block 1123 includes two mounting plates 230 arranged side by side at intervals and a connecting plate 231 connecting the two mounting plates 230. An I-shaped structure is formed between the two mounting plates 230 and the connecting plate 231. The U-shaped block 210 is sleeved outside the two mounting plates 230, so that the buckle body 1121 can slide along the mounting plates 230; the two ends of the connecting rod 211 are respectively movably inserted through the corresponding slide holes 2300 and connected to the U-shaped block 210, so that the buckle body 1121 can rotate with the connecting rod 211 as the rotation axis. In addition, the slide holes 2300 are arranged as long holes, so that the connecting rod 211 can move in the slide holes 2300 along the first direction.

[0065] Therefore, when the buckle hook 1120 and the buckle body 1121 are cooperatively engaged, the buckle body 1121 is pushed by sliding so that the buckle hook 1120 disengages from the engaging groove 212 of the baffle of the U-shaped block 210, and then the buckle body 1121 is rotated so that the buckle hook 1120 disengages from the U-shaped block 210, thereby realizing the decoupling of the buckle hook 1120 and the buckle body 1121.

[0066] In another embodiment of the present application, please continue to refer to Figure 5 and Figure 6 , the elastic fastening unit 1122 includes an elastic member 220. The elastic member 220 abuts between the mounting block 1123 and the buckle body 1121. The elastic force of the elastic member 220 is used to drive the buckle body 1121 to move away from the buckle hook 1120 along the first direction.

[0067] By abutting the elastic member 220 between the mounting block 1123 and the buckle body 1121, the elastic member 220 is used to make the buckle body 1121 always have a tendency to move away from the buckle hook 1120 along the first direction. Since there is a tendency for the buckle hook 1120 and the buckle body 1121 to move away from each other when they are engaged and cooperated, it can ensure that the two are not easily decoupled (similar to the principle of action of two hooks engaging with each other). At the same time, by pulling the buckle hook 1120 by the buckle body 1121, the buckle pressing plate 111 can be tightly abutted against the periphery of the mounting arm 10 to ensure the fixing strength of the fixing assembly 11 on the mounting arm 10.

[0068] In another embodiment of the present application, please continue to refer to Figure 5 and Figure 6 , the elastic fastening unit 1122 further includes a push plate 221 and a limiting plate 222. One side of the push plate 221 abuts against the connecting rod 211, and the other side of the push plate 221 is connected to the elastic member 220. The limiting plate 222 is installed on the mounting block 1123. Specifically, both ends of the limiting plate 222 are respectively connected to two mounting plates 230 of the mounting block 1123. One end of the elastic member 220 away from the push plate 221 is connected to the limiting plate 222, and the elastic force direction of the elastic member 220 is the first direction.

[0069] By utilizing the abutment between the push plate 221 and the connecting rod 211, the elastic abutting effect of the elastic member 220 on the buckle body 1121 is indirectly realized, and at the same time, the effect that the buckle body 1121 can rotate is ensured.

[0070] Specifically, the push plate 221 includes a pushing portion 2210 and a limiting and mounting portion 2211 that are connected to each other. The pushing portion 2210 is used to abut against the connecting rod 211, and the side surface of the pushing portion 2210 close to the connecting rod 211 has an arc surface to fit with the side circumference of the connecting rod 211. The limiting and mounting portion 2211 is a rod structure, and the elastic member 220 is a spring. The spring is sleeved on the limiting and mounting portion 2211. One end of the spring abuts against the limiting and mounting portion 2211, and the other end of the spring abuts against the limiting plate 222.

[0071] In another embodiment of the present application, please look back at Figure 2 and Figure 4 , anti-slip pads 113 are provided on the side surface of the buckle pressing plate 111 close to the mounting arm 10 and on the side surface of the fixed seat 110 close to the mounting arm 10. The anti-slip pads 113 are used to fit with the mounting arm 10. The anti-slip pads 113 are utilized to increase the friction between the fixing component 11 and the mounting arm 10, so as to improve the fixing strength between the fixing component 11 and the mounting arm 10.

[0072] In another embodiment of the present application, please refer to Figure 2 and Figure 7 , the expansion bracket 1 includes a connection structure, and the connection structure is used to rotatably connect the connection seat 12 with the fixing component 11. The connection seat 12 is installed with the auxiliary device 1000, and the connection seat 12 is rotatably connected with the fixing component 11, so that the installation angle of the auxiliary device 1000 can be adjusted. Among them, the connection structure is specifically rotatably connected with the fixed seat 110 in the fixing component 11.

[0073] When the auxiliary device 1000 is multiple groups of lamps, the multiple groups of lamps are respectively installed and connected to multiple connection seats 12, the multiple connection seats 12 are respectively rotatably connected to multiple fixing components 11, and the multiple groups of fixing components 11 are all installed on the mounting arm 10. By rotating the connection seats 12, the irradiation areas of the multiple groups of lamps can be adjusted, enabling the light spots of the multiple groups of lamps to be focused within a circular ring, or allowing the light spots of the multiple groups of lamps to hit different places on an object. Moreover, when the light colors emitted by the multiple groups of lamps are different, the background of the object can also be presented in multiple colors, thus enabling the photographed object photo to present a colorful effect and making the lighting effect more abundant.

[0074] In another embodiment of the present application, please refer to Figure 2 and Figure 7 The connection structure includes a washer 130 and a locking adjustment unit 131. The washer 130 abuts between the fixing component 11 (specifically, the fixing base 110 in the fixing component 11) and the connection seat 12. The locking adjustment unit 131 is used to connect the fixing component 11 and the connection seat 12 and adjust the tightening degree between the fixing component 11 and the connection seat 12. By adjusting the tightening degree between the connection seat 12 and the fixing base 110 through the locking adjustment unit 131, the fixing and rotational cooperation between the connection seat 12 and the fixing base 110 can be achieved. At the same time, by adding a washer 130 between the fixing base 110 and the connection seat 12 to increase friction, a damping force can be provided, enabling the fixing base 110 and the connection seat 12 to rotate relative to each other under an external force. After the external force is removed, the fixing base 110 and the connection seat 12 are relatively fixed.

[0075] Specifically, the connection seat 12 can be fastened to the fixing base 110. An annular groove is formed on the side surface of the fixing base 110 close to the connection seat 12. The washer 130 is placed in the annular groove, and a part of the washer 130 protrudes out of the annular groove and abuts against the connection seat 12.

[0076] The washer 130 can specifically be a rubber ring or a silicone rubber ring.

[0077] In another embodiment of the present application, please refer to Figure 2 and Figure 7 The locking adjustment unit 131 includes a first bolt 1310. A through hole 1101 is provided on the fixing component 11 (specifically, the fixing base 110 in the fixing component 11), and a threaded groove (not shown in the figure) is provided on the connection seat 12. The rod portion of the first bolt 1310 passes through the through hole 1101 and is threadedly connected to the threaded groove. The cap portion of the first bolt 1310 is abutted against the side surface of the fixing base 110 facing away from the connection seat 12. Thus, by rotating the first bolt 1310, the tightening degree between the fixing base 110 and the connection seat 12 can be adjusted, enabling the connection seat 12 to rotate relative to the fixing base 110 around the axis of the first bolt 1310, and further adjusting the angle of the auxiliary device 1000.

[0078] Please refer to Figure 8 In another embodiment of the present application, the mounting structure of the connecting seat 12 and the auxiliary device 1000: A fixing clip 5 is sleeved on the auxiliary device 1000. A first connecting piece 50 is provided on the fixing clip 5, and a second connecting piece 120 is provided on the connecting seat 12. A second bolt 51 passes through the first connecting piece 50 and the second connecting piece 120 and is threadedly connected to a nut 52, pressing the first connecting piece 50 and the second connecting piece 120 against each other, thereby realizing the mounting connection between the fixing clip 5 and the connecting seat 12. By rotating the second bolt 51, the pressing degree between the first connecting piece 50 and the second connecting piece 120 can be adjusted, so that the first connecting piece 50 and the second connecting piece 120 can rotate around the axis of the second bolt 51, thereby adjusting the angle of the auxiliary device 1000. Among them, the first connecting piece 50 can be a plastic part or a silicone part, etc.; the second connecting piece 120 can be a plastic part or a silicone part, etc.

[0079] Further, when the axis of the second bolt 51 is perpendicular to the axis of the first bolt 1310, the angle adjustment of the auxiliary device 1000 in three-dimensional space can be realized.

[0080] Please refer to Figure 9 The present application also provides an underwater photography bracket, including a photography bracket 2 and the extension bracket 1 provided by the embodiment of the present application. The extension bracket 1 is connected to the photography bracket 2.

[0081] During use, a photographic device 2000 is installed on the photography bracket 2, and the corresponding auxiliary device 1000 is installed on the extension bracket 1 according to requirements, thereby achieving a better underwater photography effect.

[0082] The underwater photography bracket provided by the present application adopts the extension bracket 1 provided by the present application, which can realize the installation of multiple auxiliary devices 1000, provides a better underwater photography effect for underwater photography, and greatly improves the convenience and controllability of underwater photography.

[0083] In another embodiment of the present application, the extension bracket 1 and the photography bracket 2 are detachably connected to further improve the controllability of the underwater photography bracket.

[0084] Specifically, please refer to Figure 9, the underwater photography support further includes an assembly frame 3 and an adjustment knob 4. The end of the mounting arm 10 of the extension support 1 is provided with a first spherical structure 100, and the photography support 2 is provided with a second spherical structure 20. The assembly frame 3 includes two oppositely arranged clamping plates, and two accommodating grooves are formed between the two clamping plates. The two accommodating grooves are respectively for placing the first spherical structure 100 and the second spherical structure 20, and the adjustment knob 4 is used to adjust the distance between the two clamping plates. By tightening the adjustment knob 4, the first spherical structure 100 and the second spherical structure 20 are clamped between the two clamping plates to achieve installation and fixation. By slightly loosening the adjustment knob 4, the installation angle between the extension support 1 and the photography support 2 can also be adjusted.
