Folding support and soft light cover

Abstract

The utility model provides a folding support and a soft light cover. The folding support comprises a main body, an overturning plate, a first bone strip and a second bone strip. The turnover plate can be rotatably connected to the main body, the first ribs are connected to the main body, the second ribs are connected to the turnover plate, and the number of the second ribs is smaller than that of the first ribs. The main body is arc-shaped, and a notch is formed between two tail ends of the arc-shaped main body. When the overturning plate rotates towards the direction far away from the window of the main body and rotates into the notch, the overturning plate and the main body can form a closed structure in an enclosing mode, and the lighting effect umbrella cover is opened. When the turnover plate leaves the notch and rotates towards the window close to the main body, the turnover plate can be folded on one side of the main body, and the lighting effect umbrella cover is folded. According to the folding support, when the soft light cover is unfolded, only the overturning plate needs to be rotated to drive a small number of the ribs to overturn, and due to the fact that the number of the ribs needing to be overturned at the same time is small, needed overturning force is small, and operation is convenient.

Description

Technical Field

[0001] This utility model relates to the field of photographic and video equipment technology, and in particular to a folding bracket and a softbox. Background Technology

[0002] With the continuous development of photography and videography technology, the requirements for lighting effects are becoming increasingly stringent. In order to achieve better lighting effects, modern large photography and videography lights are usually equipped with photography accessories such as diffusers.

[0003] Because the diffuser has an umbrella-shaped reflective surface, it occupies a large area when unfolded. In order to meet the needs of transportation and storage, existing diffusers are all equipped with a foldable structure to store the umbrella ribs inside the diffuser.

[0004] Some diffusers on the market today have half of their ribs mounted on a flip assembly and the other half on a fixed assembly. When stored, the ribs on the flip assembly move closer to the corresponding ribs on the fixed assembly to reduce the storage volume. However, since half of the ribs are mounted on the flip assembly, when the diffuser is opened, that part of the ribs needs to flip simultaneously, resulting in a large flipping force and making it inconvenient to operate. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the folding structure of the diffuser in the prior art is difficult to flip and inconvenient to operate.

[0006] To solve the above-mentioned technical problems, this utility model provides a folding bracket, which includes: a main body, the main body having a window for the light fixture or light emitted by the light fixture to pass through; the main body is arc-shaped, and a notch is formed between the two ends of the arc; a flip plate, the flip plate being rotatably connected to the front end of the main body, and the flip plate can be flipped into the notch, the two sides of the flip plate being respectively connected to the two ends of the main body; and a rib, including a first rib disposed on the main body and a second rib disposed on the flip plate; the first rib is disposed on the front end of the main body and extends outward from the outer periphery of the main body. The second rib has at least two members, and the number of second ribs is less than the number of first ribs; the first rib and the second rib are used to connect the light-effect umbrella surface; wherein, when the flip plate rotates towards the window direction away from the main body and rotates into the notch, the flip plate can enclose the main body to form a closed structure, and the light-effect umbrella surface connected to the first rib and the second rib opens; when the flip plate leaves the notch and rotates towards the window direction close to the main body, the flip plate can fold into one side of the main body, and the light-effect umbrella surface connected to the first rib and the second rib closes.

[0007] In some embodiments of this application, the main body is provided with insertion holes at both ends corresponding to the notch; the flip plate is provided with two connecting arms, both of which are movably disposed on the flip plate, and the connecting arms can extend from both sides of the flip plate or retract into the flip plate; when the flip plate is in the notch, the two connecting arms can extend and respectively engage with the two insertion holes, thereby keeping the main body and the flip plate locked; when the two connecting arms retract into the flip plate, the two connecting arms are separated from the two insertion holes respectively, thereby releasing the main body and the flip plate from the notch, and the flip plate can leave the notch.

[0008] In some embodiments of this application, the two connecting arms move on the flip plate, allowing them to move closer or further apart. Each connecting arm moves between a disengaged position and a engaged position. When the connecting arm is in the engaged position, its end engages with the socket. When the connecting arm is in the disengaged position, its end disengages from the socket. The main body also includes a tension spring disposed between the two connecting arms. One end of the tension spring is connected to one connecting arm, and the other end is connected to the other connecting arm. When an external force brings the two connecting arms closer together, the connecting arms can move to the disengaged position, and the tension spring is compressed. After the external force is released, the tension spring can drive the two connecting arms to move to the engaged position.

[0009] In some embodiments of this application, the folding bracket further includes a flip seat, and two flip seats are provided, which are spaced apart on the front end surface of the main body; the flip plate is rotatably connected between the two flip seats.

[0010] In some embodiments of this application, a limiting cavity is provided on the main body, and a first opening is provided on the outer peripheral side of the limiting cavity away from the window. The first rib can extend into the limiting cavity through the first opening and is rotatably disposed in the limiting cavity. A mounting position is provided on the flip plate, and the second rib is rotatably disposed at the mounting position.

[0011] In some embodiments of this application, when the flip plate is in the notch, the light-effect umbrella surface connected to the first rib and the second rib opens, and the limiting cavity and the mounting position are on the same plane.

[0012] In some embodiments of this application, the limiting cavity is provided in multiple ways, and the multiple limiting cavities are arranged at intervals on the main body; the opening angle of the limiting cavity gradually increases in the direction away from the flip seat and towards the flip seat.

[0013] In some embodiments of this application, the main body is C-shaped and the notch on the main body is connected to the window, and the flip plate is rotatably disposed at the notch of the main body; when the flip plate is in the notch, the flip plate can surround the main body to form a ring structure.

[0014] In some embodiments of this application, the main body is C-shaped and an arc-shaped baffle is provided between the notch on the main body and the window, the baffle separating the notch from the window; when the flip plate is in the notch, the flip plate can form a ring structure with the main body.

[0015] This utility model also provides a diffuser, which includes the aforementioned folding bracket, light-effect umbrella surface, and chuck. The light-effect umbrella surface is connected to the first rib and the second rib, and the inner surface of the light-effect umbrella surface forms a reflective surface capable of reflecting light. The chuck is detachably installed at the rear end of the window. The chuck can be used to install the lamp, and the folding bracket is connected to the lamp via the chuck.

[0016] As can be seen from the above technical solution, the beneficial effects of this utility model are as follows: In the folding bracket and diffuser of this utility model, the folding bracket includes a main body, a flip plate, and ribs. The flip plate is rotatably connected to the main body, the first rib is connected to the main body, and the second rib is connected to the flip plate. The number of second ribs is less than the number of first ribs. Light-emitting umbrella surfaces are connected to the first and second ribs. The main body is arc-shaped, with a notch formed between the two ends of the arc. The two sides of the flip plate can respectively connect to the two ends of the main body. When the flip plate rotates towards the window direction away from the main body and into the notch, the flip plate can enclose the main body to form a closed structure, and the light-emitting umbrella surfaces connected to the first and second ribs open. When the flip plate leaves the notch and rotates towards the window direction closer to the main body, the flip plate can fold to one side of the main body, and the light-emitting umbrella surfaces connected to the first and second ribs retract. Therefore, by using the flip plate, which occupies only a small part of the enclosed structure, and the number of second ribs on the flip plate is less than the number of first ribs on the main body, when unfolding the diffuser, only the flip plate needs to be rotated to rotate a small number of ribs. The rotation force required to rotate a small number of ribs is also small, making it easier and more convenient for users to operate. Attached Figure Description

[0031] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0034] Some diffusers on the market today have half of their ribs mounted on a flip assembly and the other half on a fixed assembly. When stored, the ribs on the flip assembly move closer to the corresponding ribs on the fixed assembly to reduce the storage volume. However, since half of the ribs are mounted on the flip assembly, when the diffuser is opened, that part of the ribs needs to flip simultaneously, resulting in a large flipping force and making it inconvenient to operate.

[0035] Figure 1 This is a schematic diagram of the structure of the diffuser 10 in one embodiment of this utility model. Figure 2 yes Figure 1 A structural diagram from another perspective.

[0036] Please see Figure 1 and Figure 2 As shown, one embodiment of this application provides a diffuser 10, which can be used in conjunction with a lamp to process the light emitted by the lamp, thereby enhancing the light efficiency of the lamp.

[0037] In some embodiments, the diffuser 10 of this application may include a folding bracket 1 and a light-effect umbrella surface 2 connected to the folding bracket 1. The inner surface of the light-effect umbrella surface 2 forms a reflective surface capable of reflecting light. The folding bracket 1 includes a main body 11, a flip plate 12, and ribs. The light-effect umbrella surface 2 can be connected to the ribs, which can rotate relative to the main body 11 via the flip plate 12. This rotation allows the ribs to move closer together, thus opening or closing the light-effect umbrella surface 2.

[0038] In some embodiments, the light-effect umbrella surface 2 can be a reflective fabric. It should be noted that the light-effect umbrella surface 2 can also be a diffuser fabric or a component with other light-effect properties.

Figure 5 yes Figure 4 A structural diagram from another perspective. Figure 6 yes Figure 2 A schematic diagram of the structure of the flip plate 12 in another state.

[0040] Please see Figures 3 to 6 As shown, in some embodiments, the main body 11 may be arc-shaped. A notch 112 may be formed between the two ends of the arc of the main body 11. A window 111 is provided in the middle of the main body 11. The window 111 may extend through opposite sides of the main body 11. The main body 11 can be used to connect a lamp, and the light emitted by the lamp can pass through the window 111. A light-effect umbrella 2 may be connected to one side of the main body 11, and the light emitted by the lamp can reach the inner surface of the light-effect umbrella 2 after passing through the window 111, thereby performing light effect processing.

[0041] In some embodiments, a plurality of first ribs 13 may be connected to the body 11. The plurality of first ribs 13 may be arranged at intervals on the peripheral edge of the body 11. The plurality of first ribs 13 may be rotatably rotated relative to the body 11.

[0042] In some embodiments, the central angle of the body 11 can be greater than 180 degrees, so that the arc of the body 11 can be greater than a semicircle, thereby enabling more first ribs 13 to be connected on the body 11.

[0043] In some embodiments, the flip plate 12 is rotatably connected to the front end of the main body 11. The two sides of the flip plate 12 can be respectively connected to the two ends of the main body 11. The flip plate 12 is capable of rotating relative to the main body 11.

[0044] In some embodiments, a plurality of second ribs 14 may be connected to the flip plate 12. At least two second ribs 14 are provided. The plurality of second ribs 14 can rotate relative to the flip plate 12.

[0045] In some embodiments, the flip plate 12 may be arc-shaped. The central angle of the flip plate 12 may be less than 180 degrees. This allows only a small number of second ribs 14 to be installed on the flip plate 12.

[0046] In some embodiments, the flip plate 12 rotates relative to the main body 11. When the flip plate 12 rotates toward the window 111 away from the main body 11, the flip plate 12 can flip into the notch 112. At this time, the flip plate 12 can enclose the main body 11 to form a closed structure, allowing the light-effect umbrella 2 connected to the first rib 13 and the second rib 14 to open. Thus, by rotating the flip plate 12 into the notch 112, the light-effect umbrella 2 can be opened quickly. Its operation is simple and convenient, well meeting the requirements of fast-paced shooting scenes.

[0047] In some embodiments, when the flip plate 12 is rotated away from the notch 112 and toward the window 111 near the main body 11, the flip plate 12 can be folded to one side of the main body 11, causing the light-effect umbrella 2 connected to the first rib 13 and the second rib 14 to be retracted. Thus, by rotating the flip plate 12 away from the notch 112 and toward the window 111 near the main body 11, the light-effect umbrella 2 can be quickly retracted. Its operation is simple and convenient, and it well meets the requirements of fast-paced shooting scenes.

[0048] In some embodiments, the flip plate 12 can be flipped into the notch 112, and the flip plate 12 can also be flipped away from the notch 112, thereby realizing the opening or closing of the light effect umbrella 2. Thus, since the flip plate 12 occupies only a small part of the enclosed annular structure, and the number of second ribs 14 on the flip plate 12 is less than the number of first ribs 13 on the main body 11, when unfolding the diffuser 10, it is only necessary to rotate the flip plate 12 to drive a small number of ribs to flip. Since the number of ribs that need to be flipped at the same time is small, the required flipping force is also small, and the operation is more convenient.

[0049] In some embodiments, the first rib 13 and the second rib 14 may be made of an elastic material. When the flip plate 12 rotates toward the interior of the window 111 away from the main body 11, the first rib 13 and the second rib 14 can bend under the pull of the light-effect umbrella 2, and unfold the light-effect umbrella 2 into an umbrella shape. When the flip plate 12 rotates toward the interior of the window 111 closer to the main body 11, the first rib 13 and the second rib 14 can elastically return to a straight shape, and the plurality of first ribs 13 and the plurality of second ribs 14 face the same direction, so as to facilitate the storage of the diffuser 10.

[0050] In this embodiment, the diffuser 10 may include eight ribs. Preferably, two second ribs 14 are mounted on the flip plate 12. Six first ribs 13 are mounted on the main body 11. Therefore, when opening the diffuser 10, only the flip plate 12 needs to be rotated, thereby flipping two of the second ribs 14, which requires less force than the prior art that requires flipping four second ribs 14.

[0051] In some embodiments, the folding bracket 1 may include a flip base 15. The flip base 15 may be disposed on the front end surface of the main body 11. A flip plate 12 may be connected to the flip base 15. Both the flip base 15 and the flip plate 12 have shaft holes. When the flip plate 12 is mounted on the flip base 15, the two shaft holes may be arranged facing each other. A rotating shaft passes through the two shaft holes, allowing the flip plate 12 to rotate relative to the flip base 15, and thus relative to the main body 11. The flip plate 12 may rotate toward the interior of the window 111 away from the main body 11. In addition, the flip plate 12 may also rotate toward the interior of the window 111 closer to the main body 11.

[0052] In some embodiments, two flip seats 15 may be provided. The two flip seats 15 may be arranged at intervals on the front end surface of the main body 11. A flip plate 12 may be disposed between the two flip seats 15. The flip plate 12 is capable of rotating relative to the two flip seats 15. Thus, the use of two flip seats 15 can improve the stability of the flip plate 12 when rotating relative to the main body 11.

[0053] Please see Figures 3 to 6 As shown, in some embodiments, the main body 11 may be C-shaped. Both ends of the main body 11 corresponding to the notch 112 may be provided with insertion holes 113. Two connecting arms 121 may be provided on the flip plate 12; both connecting arms 121 are movably disposed on the flip plate 12, and the two connecting arms 121 can extend from both sides of the flip plate 12 or retract into the flip plate 12.

[0054] When the flip plate 12 rotates toward the window 111 away from the main body 11 and rotates into the notch 112, the flip plate 12 can enclose the main body 11 to form a closed structure.

[0055] When the flip plate 12 is housed within the notch 112, the ends of the connecting arms 121 can engage with the sockets 113, thereby opening the light-effect umbrella 2 and locking the main body 11 and the flip plate 12. When the two connecting arms 121 retract into the flip plate 12, the two connecting arms 121 separate from the two sockets 113 respectively, thereby unlocking the main body 11 and the flip plate 12. The flip plate 12 can then move away from the notch 112 and rotate toward the window 111 near the main body 11, thereby retracting the light-effect umbrella 2.

[0056] It should be noted that in some other embodiments, only one socket 113 and one connecting arm 121 may be provided. The socket 113 and the connecting arm 121 may be provided at the relative positions of the main body 11 and the flip plate 12, respectively.

[0057] In some embodiments, the movement trajectory of the connecting arm 121 is consistent with the arcuate extension direction of the flip plate 12. Both connecting arms 121 move relative to the flip plate 12 so that both connecting arms 121 can extend or retract into the flip plate 12.

[0058] Figure 7 yes Figure 4 A schematic diagram of the middle section. Figure 8 yes Figure 7 A schematic diagram of the middle section.

[0059] Please see Figure 7 and Figure 8 As shown, in some embodiments, the connecting arm 121 may include a locking tongue 1211 and a sliding part 1212 connected to one end of the locking tongue 1211. The locking tongue 1211 is arc-shaped, and the extending direction of the locking tongue 1211 is consistent with the extending direction of the flip plate 12. The end of the locking tongue 1211 opposite to the sliding part 1212 is used to engage with the socket 113.

[0060] The end of the sliding part 1212 is arranged on the outside of the flip plate 12. The sliding part 1212 is used by the user to hold the connecting arm 121 and apply external force to it, thereby moving the connecting arm 121 relative to the flip plate 12.

[0061] In some embodiments, the flip plate 12 is provided with a groove 122. The groove 122 may be arc-shaped. The locking tongue 1211 of the connecting arm 121 is movably accommodated in the groove 122.

[0062] In some embodiments, the connecting arm 121 can move relative to the flip plate 12, allowing the end of the latch 1211 to extend from both ends of the slide groove 122 or retract into the slide groove 122. The end of the latch 1211 extends out of the flip plate 12 and engages in the insertion hole 113 of the main body 11, thereby forming a complete annular structure with the flip plate 12 and the main body 11, allowing the light-effect umbrella surface 2 to open. At this time, the flip plate 12 can be accommodated in the notch 112, the surface of the flip plate 12 is flush with the surface of the main body 11, and both ends of the flip plate 12 are respectively opposite to the two ends of the main body 11 where the insertion hole 113 is located.

[0063] When the locking tongue 1211 retracts into the slide groove 122, the locking tongue 1211 can disengage from the insertion hole 113 on the main body 11, thereby allowing the flip plate 12 to rotate relative to the main body 11 and fold to one side of the main body 11, so that the light effect umbrella surface 2 can be retracted.

[0064] In some embodiments of this application, two connecting arms 121 move within a groove 122 of the flip plate 12, allowing the two connecting arms 121 to move closer or further apart. Each connecting arm 121 can move between a disengaged position and a engaged position. When the connecting arm 121 is in the engaged position, its end can engage with the socket 113; when the connecting arm 121 is in the disengaged position, its end is disengaged from the socket 113.

[0065] Please see Figure 7 and Figure 8 As shown, in some embodiments, the flip plate 12 also includes a tension spring 123. The tension spring 123 may be disposed between the two connecting arms 121. One end of the tension spring 123 may be connected to one connecting arm 121, and the other end of the tension spring 123 may be connected to the other connecting arm 121. When the user applies an external force to the connecting arms 121 to bring the two connecting arms 121 closer together, the connecting arms 121 can move to the disengaged position. At this time, the tension spring 123 may be in a compressed state, and the end of the connecting arm 121 may disengage from the socket 113, so that the flip plate 12 can rotate relative to the main body 11 and fold into one side of the main body 11.

[0066] When the external force is released, the tension spring 123 can elastically reset and drive the two connecting arms 121 to move away from each other, so that the connecting arms 121 move to the engaging position, and the end of the connecting arm 121 can be engaged in the insertion hole 113, thereby making the main body 11 and the flip plate 12 enclose to form a complete ring structure.

[0067] Please see Figure 5 As shown, in some embodiments, a limiting cavity 114 may be formed on the main body 11. A first opening 1141 may be formed on the side of the limiting cavity 114 opposite to the window 111, and the first bone strip 13 can be inserted through the first opening 1141 and rotatably disposed in the limiting cavity 114.

[0068] In some embodiments, multiple limiting cavities 114 may be provided. The multiple limiting cavities 114 may be arranged at intervals. The multiple limiting cavities 114 may be configured in a one-to-one correspondence with multiple first ribs 13.

[0069] In some embodiments, the opening angle of the limiting cavity 114 gradually increases in the direction from away from the flip base 15 to near the flip base 15. Thus, when the light effect umbrella 2 is opened, a plurality of first ribs 13 can be arranged to extend radially along the window 111 to unfold the light effect umbrella 2.

[0070] In some embodiments, the body 11 further includes a torsion spring. The end of the first rib 13 can be connected to the limiting cavity 114 of the body 11 by the torsion spring.

[0071] In some embodiments, the flip plate 12 may have a mounting position, and the second rib 14 is rotatably disposed within the mounting position. The mounting position may be a receiving cavity 124. The second rib 14 is rotatably disposed within the receiving cavity 124. The receiving cavity 124 may have a second opening on the side facing away from the window 111. The second rib 14 can extend into the limiting cavity 114 through the second opening. The second rib 14 can rotate at the second opening.

[0072] When the diffuser 10 is needed, the flip plate 12 unfolds and forms a complete ring structure with the main body 11. A torsion spring then pushes the first rib 13 to rotate within the limiting cavity 114, and the second rib 14 to rotate within the receiving cavity 124, causing the light-effect umbrella 2 to unfold rapidly, thus opening the diffuser 10 for use. When the diffuser 10 is no longer needed, the flip plate 12 rotates relative to the main body 11 and folds to one side of the main body 11. The torsion spring then pushes the first rib 13 to rotate, causing the light-effect umbrella 2 to retract rapidly, thus folding the diffuser 10.

[0073] In some embodiments, when the flip plate 12 rotates toward the interior of the window 111 away from the main body 11 and into the notch 112, the light effect umbrella surface 2 connected to the first rib 13 and the second rib 14 can be opened, so that the light effect umbrella surface 2 can remain open. At this time, the limiting cavity 114 and the mounting position are on the same plane, so that the first rib 13 and the second rib 14 are on the same horizontal plane. The first rib 13 can be rotated to be arranged radially along the window 111, and the second rib 14 can be rotated to be arranged radially along the window 111, so that the light effect umbrella surface 2 opens to form an umbrella shape, thereby making the umbrella-shaped structure formed by the diffuser 10 more uniform after it is unfolded.

[0074] In some embodiments, when the flip plate 12 moves away from the notch 112 and rotates toward the inside of the window 111 closer to the main body 11, the flip plate 12 folds up to one side of the main body 11, so that the light effect umbrella surface 2 is closed. At this time, the first rib 13 and the second rib 14 can extend in the same direction, which facilitates the storage of the folding bracket 1.

[0075] Figure 9 yes Figure 4 A structural schematic diagram of another embodiment. Figure 10 yes Figure 9 The exploded diagram.

[0076] Please see Figure 10 and Figure 11 As shown, in some embodiments, the diffuser 10 may also include a chuck 3, which is detachably mounted on the body 11.

[0077] In some examples, the chuck 3 includes a chuck body 31 and a flange 32 disposed on the chuck body 31. The chuck body 31 is a cylindrical structure with open ends and a hollow interior.

[0078] The flange portion 32 is annular and is located on the outer periphery of the opening at one end of the disk body 31. The chuck 3 may be provided with a locking block portion 33. The locking block portion 33 may be located on the outer wall of the disk body 31 and near the opening at the other end of the disk body 31. The locking block portion 33 is used to connect with the lamp and is fixed to the body 11 by the chuck 3.

[0079] In this example, the inner side of the main body 11 may be provided with a fixing groove 115, and the flange portion 32 of the chuck 3 is detachably engaged in the fixing groove 115. The detachable connection between the chuck 3 and the main body 11 allows the main body 11 to be matched with multiple models of chuck 3, thereby enabling the connection of different types of lamps.

[0080] In some embodiments, one end of the fixing groove 115 can be an inlet / outlet end. The chuck 3 can enter or exit the fixing groove 115 from the inlet / outlet end.

[0081] In some embodiments, the locking block 33 can be directly fixed to the main body 11 without the chuck 3. The locking block 33 can also have various structural forms, such as a slot structure, a snap-on structure, a hook structure, etc. By providing different types of locking blocks 33 on the main body 11, it is also possible to connect the main body 11 with various types of lamps.

[0082] In some embodiments, the main body 11 may also include a movable button block 116, which is arranged on the surface of the main body 11 in the area corresponding to the path of the chuck 3 in and out of the inlet / outlet end, and the moving direction of the button block 116 is consistent with the thickness direction of the main body 11.

[0083] The button stop 116 can move relative to the main body 11, protruding from the surface of the main body 11 or being housed inside the main body 11. When the button stop 116 protrudes from the surface of the main body 11, it can stop against the outer side of the flange 32. Specifically, the chuck 3 can be engaged in the fixing groove 115, and the button stop 116 stops the chuck 3, thus stably fixing it to the main body 11.

[0084] When it is necessary to remove the chuck 3 from the body 11, or to replace it with a different type of chuck 3, the button block 116 can be pressed to house the button block 116 inside the body 11, so that the button block 116 can disengage from the chuck 3, thereby allowing the chuck 3 to disengage from the fixing groove 115 and be removed from the body 11.

[0085] In some embodiments, a button spring can be provided at the bottom of the button stop 116. The button stop 116 can move relative to the main body 11 by means of the elastic extension and contraction of the button spring, so as to protrude from the surface of the main body 11 or be housed inside the main body 11. In other examples, the button stop 116 can be provided as a flexible component, such as being made of flexible materials such as rubber or silicone. The movement of the button stop 116 relative to the main body 11 is achieved based on the elasticity of the button stop 116 itself.

[0087] Please see Figures 11 to 13 As shown, in some embodiments, the main body 11 may be C-shaped. A notch 112 may be formed on one side of the main body 11. The folding bracket 1 also includes a baffle 16. The baffle 16 may be arc-shaped. The baffle 16 can separate the notch 112 from the window 111. The baffle 16 can be connected to the notch 112 of the main body 11. When the flip plate 12 rotates toward the window 111 away from the main body 11 and rotates into the notch 112, the flip plate 12 can surround the main body 11 to form a ring structure. Thus, by connecting the two ends of the notch 112 with the baffle 16, the overall structural strength of the main body 11 can be increased. At the same time, the baffle 16 also has a limiting effect on the flip plate 12, preventing the flip plate 12 from continuing to rotate after it has rotated to the notch 112.

[0088] It should be noted that in some other embodiments, the main body 11 and the baffle 16 can be connected separately. Alternatively, the main body 11 and the baffle 16 can be integrally formed, in which case the middle part of the main body 11 can be enclosed to form a complete circular cavity, thereby further improving the overall structural strength of the main body 11.

[0089] As can be seen from the above technical solution, the beneficial effects of this utility model are as follows: In the folding bracket 1 and diffuser 10 of this utility model, the folding bracket 1 includes a main body 11, a flip plate 12, and ribs. The flip plate 12 is rotatably connected to the main body 11. A first rib 13 is connected to the main body 11, and a second rib 14 is connected to the flip plate 12. The number of second ribs 14 is less than the number of first ribs 13. A light-effect umbrella surface 2 is connected to the first rib 13 and the second rib 14. The main body 11 is arc-shaped, and a notch 112 is formed between the two ends of the arc shape of the main body 11. The two sides of the flip plate 12 can respectively connect to the two ends of the main body 11.

[0090] Specifically, when the flip plate 12 rotates towards the window 111 away from the main body 11 and into the notch 112, the flip plate 12 can enclose the main body 11 to form a closed structure, and the light-effect umbrella surface 2 connected to the first rib 13 and the second rib 14 opens; when the flip plate 12 leaves the notch 112 and rotates towards the window 111 closer to the main body 11, the flip plate 12 can fold into one side of the main body 11, and the light-effect umbrella surface 2 connected to the first rib 13 and the second rib 14 retracts. Thus, since the flip plate 12 occupies only a small part of the enclosed annular structure, and the number of second ribs 14 on the flip plate 12 is less than the number of first ribs 13 on the main body 11, when unfolding the diffuser 10, only the flip plate 12 needs to be rotated to rotate a small number of ribs. Because the number of ribs that need to be rotated at the same time is small, the required rotation force is also small, making the operation more convenient.

[0091] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
