[0022] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] It should also be noted here that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0024] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0025] Example:

[0026] like Figure 1-6 A light distribution support frame includes a support component 100 and a connecting component 200. The connecting component 200 includes a connecting seat 210 and a connecting head 220. A limited cavity is formed in the connecting seat 210, which is connected to a movable groove 201 that forms a folding trajectory of the support component 100 and a positioning groove 202 for keeping the support component 100 in an expanded state; the support component 100 includes a rotating joint 110 and a support rod 120. A ball groove 203 is formed in the limiting cavity. The rotating joint 110 can rotate in the ball groove 203. The support component 100 switches between the movable groove 201 and the positioning groove 202 as the rotating joint 110 switches to realize the folding or expansion of the light distribution support frame. It can be understood that when it is necessary to unfold, the support assembly 100 can be rotated into the positioning groove 202 to make the support assembly 100 spread out in all directions; when it is necessary to fold, the support assembly 100 can be separated from the positioning groove 202 and the rotating structure 110 can be rotated in the ball groove 203 to enter the movable groove 201 to achieve folding. It is simple and convenient to use.

[0027] In this embodiment, the rotary joint 110 includes a ball head 111 and a fixing post 112. The end of the support rod 120 is fixedly connected to the fixing post 112. Specifically, the fixing can be performed by plugging, snapping, threading, ultrasonic welding, etc. Of course, it is understandable that in other embodiments, the rotary joint 110 and the support rod 120 can also be integrally formed.

[0028] In this embodiment, clamping blocks 2021 for fixing the support component 100 are provided on both sides of the positioning groove 202. It can be understood that the clamping blocks 2021 can be made of materials with a certain elasticity, such as plastic, metal, etc. After the support component 100 is embedded in the positioning groove 202, the clamping blocks 2021 are squeezed open, generating elastic force, clamping the support component 100, and achieving the positioning effect.

[0029] In this embodiment, the connecting seat 210 includes an upper connecting plate 211 and a lower connecting plate 212. After being spliced ​​together, the upper connecting plate 211 and the lower connecting plate 212 form a movable channel 204 connecting the movable groove 201 and the positioning groove 202, providing a movable space for the movable trajectory of the support component 100.

[0030] In this embodiment, the connector 220 includes a cover plate 221 and a rotating connection seat 222. The cover plate 221 is fixedly connected to the top of the upper connecting plate 211 and has a mounting opening 2211 running through the middle. The rotating connection seat 222 includes a turntable 2221 and a connecting rod 2222. A rotation space is formed between the cover plate 221 and the upper connecting plate 211. The turntable 2221 is installed between the cover plate 221 and the upper connecting plate 211. The cover plate is provided with a through screw hole, and a positioning bolt 223 is provided in the through screw hole to fix the turntable. It can be understood that by tightening the positioning bolt 223, the position of the turntable 2221 can be kept relatively fixed, thereby adjusting the angle of use of the light distribution.

[0031] In this embodiment, the connecting rod 2222 includes a first connecting rod 2223 and a second connecting rod 2224 that are rotatably connected. One end of the first connecting rod 2223 is fixedly connected to the rotating disk 2221, and the other end is rotatably connected to the second connecting rod 2224. The first connecting rod 2223 and the second connecting rod 2224 are connected by a locking bolt 2225. It is understood that a threaded hole for the locking bolt 2225 to pass through is formed at the connection, and the locking bolt 2225 serves as a rotating shaft.

[0032] In this embodiment, a connecting disc 22226 is provided at one end of the first connecting rod 2223, and first teeth are provided on both sides of the connecting disc. A connecting clip 2227 is provided at one end of the second connecting rod 2224, and a sliding groove is provided on the inner wall of the connecting clip 2227. A toothed disc 2228 is provided between the connecting clip 2227 and the connecting disc 2226. One end of the toothed disc 2228 is provided with second teeth, and the other end is provided with a slider adapted to the sliding groove. The first teeth and the second teeth engage with each other. The engagement of the first and second teeth increases the resistance between the first connecting rod 2223 and the second connecting rod 2224, thereby stabilizing the support angle of the support frame. It is understood that the connecting rod 2222 is made of plastic, and the tightness of the locking bolt 2225 can adjust the preset resistance. When the user applies a force exceeding the preset resistance, the meshing gears can disengage for angle adjustment.

[0033] In this embodiment, an expansion interface 2228 is provided at one end of the second connecting rod 2224 away from the connecting clip 2227 for connecting to other supporting accessories such as a tripod.

[0034] In this embodiment, at least four movable grooves 201 are symmetrically arranged along the circumference of the connecting assembly 200 , and the number of the positioning grooves 202 is equal to the number of the movable grooves 201 .

[0035] In this embodiment, a protective head (not shown) is provided at one end of the support rod 120 away from the rotating joint 110 to prevent the support rod 120 from being too sharp and piercing the lampshade of the fabric lamp.

[0036] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention.
