DETAILED DESCRIPTION

[0034] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention is capable of various variations in different embodiments without departing from the scope of the present invention, and that the descriptions and illustrations herein are intended to be illustrative in nature and not to limit the present invention.

[0035] In the description of this application, it should be understood that in the embodiments shown in the drawings, indications of directions or positional relationships (such as up, down, left, right, front, and back) are merely for the convenience of describing this application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions will also change accordingly.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the described features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0037] See Figure 1A lighting system includes a support frame, a light fixture 200, and a fixed support frame 100. The support frame can be a tripod or other support frame. The fixed support frame 100 is connected to the support frame, and the light fixture 200 is detachably mounted on the fixed support frame 100, so that the light fixture 200 is in an extended state under the support of the fixed support frame 100.

[0038] For example, a photography tripod with a foldable support frame has a smaller volume when folded, which can reduce storage space and facilitate portability. The cloth light 200 can be an LED cloth light. The cloth light 200 has a flexible fabric shape and can be folded or rolled up as needed to reduce storage space and facilitate portability.

[0039] In an embodiment of the present application, the fixing bracket 100 can also be folded, so that the support frame, the light distribution light 200 and the fixing bracket 100 of the lighting system can be folded separately to reduce the space occupied by the lighting system when stored and make it easy to carry.

[0040] See Figure 1 and Figure 4 The fixed bracket 100 includes a bracket outer frame 2 and a load-bearing rod 1. The load-bearing rod 1 is connected to the bracket outer frame 2 and is connected to the support frame. The cloth lamp 200 is connected to the bracket outer frame 2, and the light-emitting surface of the cloth lamp 200 faces the side away from the load-bearing rod 1. Among them, the load-bearing rod 1 and the bracket outer frame 2 are detachably connected, so that the fixed bracket 100 can be disassembled into two parts: the load-bearing rod 1 and the bracket outer frame 2, reducing the number of scattered parts after the fixed bracket 100 is disassembled, and effectively preventing the loss of parts due to too many disassembled parts. Moreover, the bracket outer frame 2 and the load-bearing rod 1 can be folded to reduce the space occupied by the bracket outer frame 2 and the load-bearing rod 1 when stored, and are easy to carry.

[0041] See Figures 7 to 10 The load-bearing rod 1 includes a first segmented rod 11, a second segmented rod 12 and a first locking member 13. The second segmented rod 12 is slidably connected to the first segmented rod 11 and can be extended and retracted along the length direction of the first segmented rod 11. The first locking member 13 connects the first segmented rod 11 and the second segmented rod 12 to lock the second segmented rod 12 to the first segmented rod 11. When the load-bearing rod 1 is used to support the bracket outer frame 2 so that the bracket outer frame 2 remains in an expanded state, the second segmented rod 12 moves to an extended state relative to the first segmented rod 11, and the extended length of the second segmented rod 12 is adapted to the length required to support the bracket outer frame 2. When the load-bearing rod 1 needs to be stored, the second segmented rod 12 moves to a retracted state relative to the first segmented rod 11, reducing the length of the load-bearing rod 1, thereby reducing the space occupied by the load-bearing rod 1 when stored, and is convenient to carry.

[0042] Specifically, the first segmented rod 11 is hollow and open at one end, i.e., the first segmented rod 11 is tubular. One end of the second segmented rod 12 is inserted into the first segmented rod 11 through the opening and is movable along the length of the first segmented rod 11 to achieve extension and retraction of the load-bearing rod 1. In other embodiments, the second segmented rod 12 can also be configured as a hollow tubular to reduce the weight of the load-bearing rod 1.

[0043] exist Figure 7 In the illustrated embodiment, the load-bearing rod 1 comprises two segments, namely, a first segment 11 and a second segment 12. In other embodiments, the load-bearing rod 1 comprises three or more segments, and the connection between two adjacent segments is similar to the connection between the first segment 11 and the second segment 12 described above.

[0044] The first locking member 13 includes a first locking block 131 and a connecting member 132. The first locking block 131 is provided with a locking cavity with an opening on one side, that is, the first locking block 131 is approximately U-shaped. The first locking block 131 has a first connecting portion 1311 and a second connecting portion 1312 on both sides of the opening for connecting the connecting member 132, and the first connecting portion 1311 is provided with a first screw hole. The first locking block 131 is sleeved on the opening of the first segmented rod 11, and the second segmented rod 12 also passes through the locking cavity of the first locking block 131, so that the inner wall surface of the locking cavity fits with the outer wall surface of the first segmented rod 11 and the second segmented rod 12.

[0045] In other embodiments, the first locking block 131 may be merely positioned within the opening of the first segmented rod 11 without direct contact with the second segmented rod 12. The connector 132 may be configured to tighten the opening of the first locking block 131 so that the first segmented rod 11 clamps the second segmented rod 12, thereby locking the second segmented rod 12 to the first segmented rod 11. Alternatively, the first locking block 131 may include two arcuate clips, with the connector 132 connected at both ends of the clips. The connector 132 may be configured to tighten the two clips so that the two clips approach each other, thereby clamping the first segmented rod 11, thereby clamping the second segmented rod 12.

[0046] See Figure 10The connecting member 132 includes a first connecting post 1321 and a first handle 1322. One end of the first connecting post 1321 passes through the first screw hole and is connected to the second connecting portion 1312. The first handle 1322 is rotatably connected to the end of the first connecting post 1321 facing away from the second connecting portion 1312, and the axis of rotation of the first handle 1322 relative to the first connecting post 1321 is perpendicular to the central axis of the first connecting post 1321. The outer surface of the first handle 1322 forms a cam structure, which abuts against the side of the first connecting portion 1311 facing away from the second connecting portion 1312. When the first handle 1322 swings in the positive direction relative to the first connecting post 1321, the contact position between the first handle 1322 and the second connecting portion 1312 changes, causing the second connecting portion 1312 to move closer to the first connecting portion 1311, thereby enabling the first locking block 131 to clamp the first segmented rod 11 and the second segmented rod 12. When the first handle 1322 swings in the opposite direction relative to the first connecting column 1321, the second connecting part 1312 moves away from the first connecting part 1311, so that the first locking block 131 releases the first segmented rod 11 and the second segmented rod 12, thereby allowing the second segmented rod 12 to extend and retract relative to the first segmented rod 11.

[0047] In this embodiment, the first connecting column 1321 and the first handle 1322 form a quick-press bolt structure with a cam handle, so that when tightening the opening of the first locking block 131, the user can pull the first handle 1322 with the cam to change the contact position between the first handle 1322 and the second connecting part 1312, thereby causing the second connecting part 1312 to move toward the direction close to the first connecting part 1311, so as to achieve the tightening of the opening of the first locking block 131, without the need for other tools, making it easy to use.

[0048] In an alternative embodiment, the connector 132 includes a first bolt and a first nut. The first nut is disposed on the second connecting portion 1312. The first bolt passes through the first screw hole of the first connecting portion 1311 and is threadedly connected to the first nut. The first bolt and the first nut cooperate to tighten the opening of the first locking block 131. In this embodiment, when adjusting the relative position between the first segmented rod 11 and the second segmented rod 12, the first bolt is rotated in the reverse direction to loosen the first segmented rod 11 and the second segmented rod 12, thereby allowing the first segmented rod 11 and the second segmented rod 12 to slide relative to each other. After the first segmented rod 11 and the second segmented rod 12 are adjusted to the desired position, the first bolt is rotated in the forward direction to bring the first connecting portion 1311 and the second connecting portion 1312 closer together to achieve tightening. This causes the first locking block 131 to clamp the outer walls of the first segmented rod 11 and the second segmented rod 12, thereby locking the first segmented rod 11 and the second segmented rod 12.

[0049] Preferably, the connecting member 132 further includes a first handle, which is connected to the first bolt, so that when adjusting the relative position between the first segmented rod 11 and the second segmented rod 12, the user can drive the first bolt to rotate relative to the first nut by turning the first handle, without the need for other tools, making it more convenient to use. Specifically, when adjusting the relative position between the first segmented rod 11 and the second segmented rod 12, it is sufficient to loosen the first bolt without removing the first bolt and the first nut, making it more convenient to adjust the first segmented rod 11 and the second segmented rod 12 and avoiding the loss of parts.

[0050] In one embodiment, the first nut is integrally fixed to the first locking block 131. Alternatively, the first locking block 131 can restrict the rotation of the first nut along its axis, preventing it from rotating synchronously with the first bolt when the first bolt is tightened. For example, the first nut is an external hexagonal nut, and the first locking block 131 has a hexagonal nut mounting hole on one side of the opening. The first nut is mounted in the nut mounting hole, and the side surface of the first nut is in contact with the nut mounting hole to restrict the first nut from rotating about its axis. In other embodiments, the first locking member 13 can also be a clamp structure.

[0051] In other embodiments, the connecting member 132 may also be a snap-lock structure.

[0052] In one embodiment, the first locking block 131 can be configured as an integral structure with the first segmented rod 11. When the first connecting portion 1311 and the second connecting portion 1312 move toward each other, the first locking block 131 clamps the second segmented rod 12.

[0053] See Figure 1 、 Figure 4 as well as Figure 7 The fixing bracket 100 further includes a connecting assembly 3, through which the load-bearing rod 1 is mounted on the support frame. The connecting assembly 3 includes a mounting seat 31 and a mounting column 32. The mounting seat 31 is connected to one of the segmented rods, and the mounting column 32 is connected to the mounting seat 31. The mounting column 32 is used to connect to the support frame, so that the load-bearing rod 1 is connected to the support frame through the mounting seat 31 and the mounting column 32. Figure 7 In the illustrated embodiment, the mounting base 31 is connected to the first segmented rod 11. In other embodiments, the mounting base 31 may also be connected to other segmented rods. The following describes the connection between the mounting base 31 and the segmented rods, taking the mounting base 31 connected to the first segmented rod 11 as an example.

[0054] The mounting base 31 is movably connected to the first segmented rod 11, and the mounting base 31 can move along the length of the first segmented rod 11, so that the user can adjust the relative position between the mounting base 31 and the first segmented rod 11 as needed to adjust the relative position between the light fixture 200 and the support frame, that is, to adjust the height position of the light fixture 200. The connecting assembly 3 also includes a second locking member 33, which is connected to the first segmented rod 11 and the mounting base 31 to lock the relative position between the first segmented rod 11 and the mounting base 31. In other embodiments, the mounting base 31 and the first segmented rod 11 can be fixedly connected. In this embodiment, the height position of the light fixture 200 can be adjusted via the support frame.

[0055] See Figure 9 and Figure 11 In one embodiment, a mounting cavity with an opening on one side is provided on the mounting seat 31, that is, the mounting seat 31 forms a structure approximately in a U shape, the mounting seat 31 is sleeved on the first segmented rod 11, and the inner wall surface of the mounting cavity is in contact with the outer wall surface of the first segmented rod 11, and the second locking member 33 connects the two sides of the opening of the mounting seat 31, and can tighten the opening of the mounting seat 31 so that the mounting seat 31 is clamped on the first segmented rod 11.

[0056] In one embodiment, the mounting seat 31 includes two symmetrically arranged arc-shaped clips, the second locking member 33 is connected to both ends of the clips, and the second locking member 33 can be tightened to bring the two clips closer to each other, so that the mounting seat 31 is fixed on the first segmented rod 11.

[0057] In one embodiment, the second locking member 33 includes a second bolt 331 and a second nut 332. The second nut 332 is arranged on one side of the opening of the mounting base 31. The second bolt 331 passes through both sides of the opening of the mounting base 31 and is threadedly connected to the second nut 332. The second bolt 331 and the second nut 332 cooperate to tighten the opening of the mounting base 31.

[0058] When adjusting the relative position between the mounting base 31 and the first segmented rod 11, the second bolt 331 is loosened to allow the mounting base 31 and the first segmented rod 11 to slide relative to each other. When the mounting base 31 and the first segmented rod 11 are adjusted to the desired position, the second bolt 331 is tightened to lock the mounting base 31 and the first segmented rod 11. When adjusting the relative position between the mounting base 31 and the first segmented rod 11, the second bolt 331 can be loosened (the second locking member 33 is still connected to the mounting base 31 at this time), and there is no need to remove the second bolt 331 and the second nut 332, which makes adjustment between the mounting base 31 and the first segmented rod 11 more convenient and avoids the loss of parts.

[0059] The second locking member 33 also includes a second handle 333, which is connected to the second bolt 331. One end of the second handle 333 extends radially along one side of the second bolt 331. The second handle 333 is used to turn the second bolt 331 about its own axis. That is, the second bolt 331 and the second handle 333 form a screw with a handle. When tightening the opening of the mounting base 31, the user can turn the second bolt 331 using the second handle 333 without the need for other tools, making it easy to use. In other embodiments, the second locking member 33 can also be a quick-release screw with a cam handle.

[0060] In one embodiment, the second nut 332 is integrally fixed to the mounting base 31. Alternatively, the mounting base 31 can limit the rotation of the second nut 332 along its axis, so that when the second bolt 331 is tightened, the second nut 332 does not rotate synchronously with the second bolt 331. For example, the second nut 332 is an external hexagonal nut, and the mounting base 31 has a hexagonal nut mounting hole on one side of the opening. The second nut 332 is installed in the nut mounting hole, and the side surface of the second nut 332 is in contact with the nut mounting hole to limit the rotation of the second nut 332 about its axis.

[0061] See Figure 7 、 Figures 11 to 13 , the connecting assembly 3 also includes a rotating shaft 34 and a third locking member 35. The rotating shaft 34 is connected to the mounting column 32 and the mounting seat 31, and enables the mounting column 32 and the mounting seat 31 to rotate around the axis of the rotating shaft 34, thereby realizing a rotational connection between the mounting column 32 and the mounting seat 31. This arrangement allows the user to adjust the angle between the mounting seat 31 and the mounting column 32 as needed to adjust the inclination angle of the cloth light 200, thereby adjusting the lighting angle of the cloth light to enhance the photographic effect. The third locking member 35 is connected to the mounting seat 31 and the mounting column 32 to limit the rotation between the mounting seat 31 and the mounting column 32, so that the cloth light 200 is fixed at the inclination position required by the user. In other embodiments, the rotating shaft 34 and the third locking member 35 may not be provided, and the mounting column 32 and the mounting seat 31 may be fixed as one.

[0062] The rotational connection between the mounting post 32 and the mounting base 31 may be:

[0063] Mode 1: The rotating shaft 34 is rotatably connected to the mounting post 32, and the rotating shaft 34 is fixedly connected to the mounting base 31. In this embodiment, the rotating shaft 34 and the mounting base 31 can be separated or integrated.

[0064] Mode 2: The rotating shaft 34 is fixedly connected to the mounting post 32, and the rotating shaft 34 is rotatably connected to the mounting base 31. In this embodiment, the rotating shaft 34 and the mounting post 32 can be separated or integrated.

[0065] Mode 3: The rotating shaft 34 is rotationally connected to the mounting post 32 and the mounting seat 31 .

[0066] Mounting base 31 is provided with an arc-shaped mounting hole 311 on the outer side of rotating shaft 34. Mounting hole 311 extends in the same direction as the trajectory of rotation of third locking member 35 about rotating shaft 34. Third locking member 35 comprises a third bolt 351 and a third nut 352. Third nut 352 is mounted on the side of mounting post 32 facing away from mounting base 31. Third bolt 351 passes through mounting hole 311 and mounting post 32 and engages with third nut 352 to clamp mounting base 31 to mounting post 32. To adjust the angle between mounting post 32 and mounting base 31, third bolt 351 is loosened to allow relative rotation between mounting post 32 and mounting base 31. Once the desired angle is reached, third bolt 351 is tightened to lock mounting post 32 and mounting base 31. Among them, when the mounting column 32 and the mounting seat 31 rotate relative to each other, after loosening the third bolt 351, the third bolt 351 can move along the mounting hole 311, and there is no need to remove the third bolt 351 and the third nut 352, making it easier to adjust between the mounting column 32 and the mounting seat 31.

[0067] The third locking member 35 also includes a third handle 353, which is connected to the third bolt 351. One end of the third handle 353 extends radially along one side of the third bolt 351. The third handle 353 is used to turn the third bolt 351 about its own axis. That is, the third bolt 351 and the third handle 353 form a screw with a handle. When tightening the third bolt 351, the user can simply turn the third handle 353 to tighten the third bolt 351, without the need for other tools, which is convenient to use. In other embodiments, the third locking member 35 can also be a quick-press screw with a cam handle.

[0068] In one embodiment, the third nut 352 is fixed to the mounting post 32 as a whole, or the mounting post 32 can limit the rotation of the third nut 352 in its axial direction, so that when the third bolt 351 is tightened, the third nut 352 does not rotate synchronously with the third bolt 351.

[0069] In one embodiment, the axis of the rotating shaft 34 is perpendicular to the length direction of the load-bearing rod 1, so that when the load-bearing rod 1 is stored, the mounting column 32 can be swung to a position parallel to the length direction of the load-bearing rod 1 to reduce the volume of the load-bearing rod 1 and the mounting column 32 when they are stored.

[0070] In other embodiments, the load-bearing rod 1 is not provided with the rotating shaft 34, and the mounting seat 31 is not provided with the arc-shaped mounting hole 311. In addition, the mounting post 32 and the mounting seat 31 rotate about the third bolt 351, that is, the mounting post 32 and the mounting seat 31 can rotate about the axis of the third bolt 351. When it is necessary to lock the relative position between the mounting post 32 and the mounting seat 31, the third bolt 351 is tightened so that the third bolt 351 and the third nut 352 clamp the mounting post 32 and the mounting seat 31, and the mounting post 32 and the mounting seat 31 cannot rotate relative to each other.

[0071] See Figure 14 The support frame 2 includes a plurality of support rods 21 that are sequentially connected and enclosed, with adjacent support rods 21 being rotatably connected. Each support rod 21 includes two or more sequentially connected rod segments, with adjacent rod segments being rotatably connected. The support rods 21 and the rod segments rotate relative to each other, allowing the support frame 2 to be expanded or collapsed as a whole.

[0072] exist Figure 14 In the illustrated embodiment, four support rods 21 are provided, connected end-to-end, and the connection between two adjacent support rods 21 is a rotational connection. The support frame 2 is quadrilateral when unfolded. In other embodiments, the support frame 2 can also be in other shapes when unfolded, such as a hexagon or octagon.

[0073] Each support rod 21 includes two connected rod segments that are rotatably connected to each other, allowing the bracket outer frame 2 to be folded or unfolded at the rotational connection between two adjacent support rods 21 and the rotational connection between two adjacent rod segments of each support rod 21. In other embodiments, each support rod 21 includes three or more rod segments arranged in sequence, such as three, four, or more segments.

[0074] Specifically, the bracket outer frame 2 also includes a corner connector 22, which connects two adjacent support rods 21 via the corner connector 22, thereby enabling the two adjacent support rods 21 to be rotatably connected. In this embodiment, the corner connector 22 includes two corner connectors 221 and a corner connecting shaft 222. The two corner connectors 221 are respectively connected to the ends of the two support rods 21 at the corners of the bracket outer frame 2. The two corner connectors 221 are rotatably connected via the corner connecting shaft 222, thereby enabling the two support rods 21 at the corners to rotate relative to each other. It should be noted that the corner connectors 22 can be connected to the support rods 21 via bolts.

[0075] like Figure 15As shown, the corner connecting rod 221 is provided with a transfer shaft portion 2211, a position-limiting recess 2212, and a position-limiting protrusion 2213. The transfer shaft portion 2211 is used to pass through the corner connecting shaft 222, thereby enabling the two corner connecting rods 221 to be rotatably connected. Specifically, the corner connecting shaft 222 passes through the transfer shaft portions 2211 of the two corner connecting rods 221, allowing the two corner connecting rods 221 to rotate relative to each other via the corner connecting shaft 222.

[0076] At the same time, the limiting recess 2212 is located at the axial front end of the adapter shaft 2211, and the limiting protrusion 2213 is located on the circumferential side of the adapter shaft 2211. After the two angle connecting rods 221 are rotatably connected through the adapter shaft 2211, the limiting protrusion 2213 on the angle connecting rod 221 and the limiting recess 2212 on the other angle connecting rod 221 are located in the same rotation plane. Therefore, the limiting protrusion 2213 on the angle connecting rod 221 can press against the limiting recess 2212 on the other angle connecting rod 221 during rotation, and limit the rotation angle between the two angle connecting rods 221.

[0077] In the embodiment where the bracket outer frame 2 is unfolded into a quadrilateral, the two corner connecting rods 221 can rotate at an angle ranging from 0 to 90 degrees, thereby preventing the two support rods 21 at the corners from excessively rotating and affecting the shape of the bracket outer frame 2. In other embodiments, the rotation angle between the two corner connecting rods 221 can be other angles. For example, when the bracket outer frame 2 is unfolded into a hexagon, the rotation angle between the two corner connecting rods 221 can be 0 to 120 degrees.

[0078] In one embodiment, a recessed portion 2214 is further provided on the corner connecting rod 221. The recessed portion 2214 is located on the peripheral side of the adapter shaft portion 2211, and the recessed portion 2214 is used to provide a connection and engagement position for the rope when the light fixture 200 is fixed to the bracket outer frame 2 via the rope. Figure 9 In the embodiment shown, the recessed portions 2214 on the two corner connectors 22 can be aligned with each other after the bracket outer frame 2 is unfolded, so that the two recessed portions 2214 are located on the same axis, and form a rope clamping position for accommodating the rope of the cloth lamp 200, so that the rope for fixing the cloth lamp 200 can be clamped in the recessed portion 2214, and the cloth lamp 200 is fixed on the bracket outer frame 2.

[0079] See Figure 2 and Figure 6The bracket outer frame 2 includes a side connector 23. The side connector 23 is connected between two connected rod segments on the same support rod 21, so that the two connected rod segments on the same support rod 21 are rotatably connected via the side connector 23. The side connectors 23 on two opposing support rods 21 are positioned correspondingly, and the rotation axes of the side connectors 23 are coaxial. The rotation axes of the side connectors 23 on two adjacent support rods 21 are perpendicular to each other, so that one opposing group of support rods 21 can rotate in a first direction, and the other opposing group of support rods 21 can rotate in a second direction, thereby achieving the storage of the bracket outer frame 2.

[0080] For example, when Figure 14 The bracket outer frame 2 shown rotates in the first direction and forms Figure 16 Then, in Figure 16 Based on the posture of the bracket outer frame 2 shown in FIG, it rotates along the second direction to form Figure 17 The posture shown, and finally formed Figure 18 The posture shown in FIG4 completes the storage of the bracket outer frame 2.

[0081] See Figure 2 In one embodiment, the side connector 23 has the same structure as the corner connector 221, and the side connector 23 can rotate an angle greater than or equal to 180 degrees. Specifically, the side connector 23 includes two side connectors 231 and a side connector shaft 232. The two side connectors 231 are respectively connected to the ends of two connected rod segments on the same support rod 21. The two side connectors 231 are rotatably connected by the side connector shaft 232, thereby enabling the two support rods 21 at the corner to rotate relative to each other.

[0082] See Figure 4 、 Figure 5 and Figure 6 , the bracket outer frame 2 also includes a fixing member 24, which is movably connected to a relative set of support rods 21 and is located at the rotation connection between two adjacent rod segments to limit the relative rotation between the two adjacent rod segments. Support members 14 are provided at both ends of the load-bearing rod 1. The support members 14 located at both ends of the load-bearing rod 1 are respectively connected to another relative set of support rods 21 and are connected to two adjacent rod segments to limit the relative rotation between the two adjacent rod segments. In this way, the bracket outer frame 2 is maintained in an expanded state through the arrangement of the fixing member 24 and the supporting member 14. In other embodiments, a fixing member 24 is provided at the rotation connection between two adjacent rod segments of each support rod 21, and the fixing member 24 is used to limit the relative rotation between the two adjacent rod segments, so that the bracket outer frame 2 is maintained in an expanded state.

[0083] The fixing member 24 includes a fixing block 241 and at least two fastening bolts 242. The fixing block 241 is connected to two connected rod segments on the same support rod 21 via the fastening bolts 242, thereby abutting the two connected rod segments to restrict relative rotation between the two connected rod segments. The two connected rod segments on the same support rod 21 are referred to below as the first rod segment 211 and the second rod segment 212 to illustrate the connection structure between the fixing member 24 and the two connected rod segments.

[0084] The fixing block 241 is provided with a first screw hole 2411 and a second screw hole 2412 at intervals along the length direction, wherein one fastening bolt 242 passes through the first screw hole 2411 and is connected to the first rod segment 211, and the other fastening bolt 242 passes through the second screw hole 2412 and is connected to the second rod segment 212, so that the first rod segment 211 and the second rod segment 212 cannot rotate relative to each other under the restriction of the fixing block 241.

[0085] exist Figure 5 In the illustrated embodiment, the first screw hole 2411 is elongated, and the second screw hole 2412 is open at one end face of the fixing block 241 along its length. This allows the fixing block 241 to slide along the length of the first rod segment 211 after the fastening bolt 242 is loosened. Furthermore, the fastening bolt 242 located in the second screw hole 2412 separates from the fixing block 241, and the fixing block 241 no longer restricts rotation between the first rod segment 211 and the second rod segment 212, allowing two connected rod segments on a support rod 21 to rotate and fold. In this embodiment, when the fixing block 241 slides along the length of the first rod segment 211, only the fastening bolt 242 needs to be loosened, without removing the fixing block 241 and the fastening bolt 242. This facilitates assembly of the fixing bracket 100 upon reuse and prevents the loss of parts.

[0086] In other embodiments, the first screw hole 2411 and the second screw hole 2412 may be circular holes. When the first rod segment 211 and the second rod segment 212 need to be rotated, the fastening bolts 242 connected to the first screw holes 2411 and the second screw holes 2412 and the fixing block 241 can be removed. In other embodiments, the fixing block 241 and the rod segments may be connected by a snap connection, eliminating the need for the fastening bolts 242.

[0087] In this embodiment, the fixing block 241 is provided with a fixing groove that matches the shape of the rod segments. The fixing block 241 is sleeved onto the first rod segment 211 and the second rod segment 212 through the fixing groove. The fixing groove in the fixing block 241 allows the fixing block 241 to surround the outside of the first and second rod segments 211, 212, and the circumference of the rod segments fits within the fixing groove of the fixing block 241.

[0088] In one embodiment, the fixing block 241 has a U-shaped cross-section and is adapted to the circumference of the first rod segment 211 and the second rod segment 212. This allows the fixing block 241 to better fit the circumference of the first rod segment 211 and the second rod segment 212, thereby limiting the position of the two connected rod segments. In other embodiments, the fixing block 241 may also be configured as a sheet-like structure or an L-shaped structure.

[0089] See Figure 2 、 Figure 3 as well as Figure 8 In the embodiment of the present application, the structure of the support member 14 is similar to that of the fixing member 24. Specifically, the support member 14 includes a support block 141 and a locking bolt 142. The support block 141 is connected to two connected rod segments on the same support rod 21 via the locking bolt 142, so that the two connected rod segments on the same support rod 21 cannot rotate relative to each other under the restriction of the support block 141.

[0090] The support block 141 is provided with a mounting groove 1411 that matches the shape of the rod segments. The support block 141 is sleeved onto two connected rod segments on the same support rod 21 through the mounting groove 1411. By providing the mounting groove 1411 on the support block 141, the support block 141 can surround the outside of the two connected rod segments, and the circumference of the rod segments fits in the mounting groove 1411 of the support block 141.

[0091] In this embodiment, the support block 141 has a U-shaped cross-section and is adapted to the circumference of the rod segment, so that the support block 141 can better fit on the circumference of the rod segment, thereby limiting the position of the two connected rod segments. In other embodiments, the support block 141 can also be configured as a sheet structure or an L-shaped structure.

[0092] exist Figure 3 In the illustrated embodiment, a positioning block 213 is provided on the rod segment, and a positioning groove 1412 is provided on the support block 141 to mate with the positioning block 213. When the support block 141 is inserted into the rod segment, the positioning block 213 engages with the positioning groove 1412, aligning the screw holes in the support block 141 with those in the rod segment, thereby facilitating installation of the locking bolt 142.

[0093] The fixed bracket 100 of the present application includes a bracket outer frame 2 and a load-bearing rod 1. The load-bearing rod 1 is detachably connected to the bracket outer frame 2, allowing the fixed bracket 100 to be disassembled into the load-bearing rod 1 and the bracket outer frame 2. This reduces the number of parts that need to be separated after the fixed bracket 100 is disassembled and effectively prevents the loss of parts due to excessive disassembly. In addition, the bracket outer frame 2 includes a plurality of support rods 21 that are connected in sequence, and two adjacent support rods 21 are rotatably connected. Each support rod 21 includes a rod body segment that is connected in sequence, and the adjacent rod body segments are rotatably connected to each other. The relative rotation between the support rods 21 and the rod body segments allows the bracket outer frame 2 to be expanded or collapsed, thereby reducing the storage volume of the bracket outer frame 2. The load-bearing rod 1 includes multiple segmented rods that are connected in sequence, and the adjacent segmented rods can move relative to each other, allowing the load-bearing rod 1 to contract, thereby reducing the storage volume of the load-bearing rod 1. This arrangement makes the fixed bracket 100 as a whole easy to carry and store.
