Description

Technical Field

[0001] The utility model relates to the technical field of photographic aids, and specifically relates to a portable spherical photographic softbox. Background Art

[0002] A softbox is a commonly used auxiliary equipment in photography. It consists of four parts: a reflective cloth, a soft light cloth, a steel wire frame, and a bayonet, and is usually used as an accessory for studio lights. The function of the softbox is to be installed on the studio light to make the emitted light softer, which helps to eliminate the light spots and shadows on the photo and improve the shooting effect. At present, most softboxes on the market are in the shape of a box or an umbrella. This design limits the light transmission range of the soft light cloth, and the light levels are not clear, which has a greater impact on the shooting effect. In addition, the existing softboxes are relatively cumbersome in terms of assembly and storage, which is not conducive to the user experience.

[0003] Chinese Patent CN220526159U discloses a portable spherical softbox for photography. The working principle of the device described in the document is that through the settings of a large chuck, a small chuck, and a support mechanism, the soft light cloth is stretched into a spherical shape, which not only improves the soft light effect of the softbox but also improves the light transmission of the soft light cloth. Specifically, a circular first placement groove is provided on the outer side of the large chuck. A first connecting ring is movably arranged in the first placement groove, and a plurality of first card slots arranged in a circular ring are provided in the first placement groove. A circular second placement groove is provided on the outer side of the small chuck. A second connecting ring is movably arranged in the second placement groove, and a plurality of second card slots arranged in a circular ring are provided in the second placement groove. One end of the support mechanism is movably connected to the first connecting ring on the large chuck, and the other end is movably connected to the second connecting ring on the small chuck. The support mechanism includes support bars and movable parts. The movable parts are respectively arranged in the corresponding first card slots and second card slots and are rotatably connected to the corresponding first connecting ring and second connecting ring. A support bar is arranged between the corresponding first card slots and second card slots. One end of the support bar is fixed to the first connecting ring through the movable part, and the other end is fixed to the second connecting ring through the movable part. When in use, the large chuck is pressed downward by an external force, so that the large chuck moves towards the small chuck, and the support mechanism is squeezed into a spherical state, and the soft light cloth is stretched accordingly. Through the setting of the holding mechanism, the support mechanism can always maintain the stretched state, so that the soft light cloth is always in the stretched state. When it needs to be stored, the holding mechanism is released, the support mechanism is folded up, and the support of the soft light cloth is released, which is convenient for storing the whole device.

[0004] The soft light cloth of this patent can only be stretched in a single state, and there is no possibility of adjusting the stretching degree of the soft light cloth, resulting in a relatively fixed soft light effect. When it is necessary to adjust the required light intensity for different scenarios, it will lose its necessity and there is a certain degree of inconvenience. Summary of the Utility Model

[0013] The beneficial effects of the present utility model compared with the prior art are as follows:

[0014] 1. Through the finely designed adjusting mechanism of the present utility model, stepless adjustment of the opening degree of the soft light cloth is realized, so that the diffusion range and intensity of light can be adjusted according to specific shooting requirements. This adjustment mechanism not only improves the applicability of the soft light box, but also enables photographers to more flexibly control the light effect and create more rich and professional photographic works. Compared with the traditional soft light box with only two states of opening and closing, the present utility model provides more adjustment possibilities, greatly improving the flexibility of shooting and the controllability of the soft light effect.

[0015] 2. The adjusting mechanism of the present utility model adopts the cooperation of multi-stage telescopic components and threaded components, making the size adjustment of the soft light box more precise and convenient. Through the meshing of internal and external threads, and the precise control of the limiting block and the limiting groove, fine adjustment of the telescopic length of the soft light box is realized, ensuring the stability and safety of the adjustment process. This design greatly reduces the risk of damage to the structure of the soft light box caused by improper adjustment, and at the same time improves the adjustment efficiency, enabling photographers to quickly adjust to the required soft light effect and adapt to the fast-paced shooting environment.

[0016] 3. The present utility model also particularly designs a fixing and locking mechanism. By aligning the fixing holes on the rotating block with the fixing holes on the base and cooperating with the insertion of the limiting block, the rapid fixing and locking of the adjusting mechanism are achieved. This locking mechanism ensures the stability of the soft light box during the shooting process, prevents the movement of the adjusting mechanism caused by accidental touch, and thus guarantees the consistency of the shooting effect. In addition, the adjusting mechanism of the present utility model is designed with simplicity of operation in mind, enabling users to quickly and accurately complete the setting and adjustment of the soft light box even under emergency or rapidly changing shooting conditions.

Detailed implementation manners

[0027] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and specific implementation manners.

[0028] Refer to Figures 1-9 : A portable spherical photographic soft light box, comprising a large chuck 1, a small chuck 2, a bayonet 3, a support mechanism 4 and an adjustment mechanism 5. The bayonet 3 is opened on the large chuck 1, and the bayonet 3 is used for installing a light source. A plurality of first card slots 11 are equidistantly arranged along the circular edge of the large chuck 1. A plurality of second card slots 21 are equidistantly arranged along the circular edge of the small chuck 2. The positions of the first card slots 11 and the second card slots 21 correspond to each other. The support mechanism 4 includes a rotating column 41 arranged in the first card slot 11 and the second card slot 21. A first rotating block 42 is rotatably connected to the rotating column 41. A support bar 43 is arranged on the first rotating block 42 of the rotating column 41 in the first card slot 11 and the second card slot 21 with corresponding positions of the large chuck 1 and the small chuck 2. The support bar 43 is used for stretching the soft light cloth. An adjustment mechanism 5 is arranged between the large chuck 1 and the small chuck 2. The adjustment mechanism 5 includes an upper adjustment block 51 fixedly connected to the large chuck 1 and a lower telescopic mechanism 52 fixedly connected to the small chuck 2. By the cooperation of the lower telescopic mechanism 52 and the upper adjustment block 51, the distance between the large chuck 1 and the small chuck 2 is adjusted, so as to adjust the degree of stretching the soft light cloth by the support mechanism 4.

[0029] In the prior art, the soft light cloth only exists in the states of being stretched and being folded up, and there is no way to adjust the degree of stretching of the soft light cloth so as to adjust the soft light effect. In this utility model, first of all, the bayonet 3 is located on the large chuck 1, and its main function is to install the light source to provide the required light for photography. A number of first card slots 11 are equidistantly arranged on the circular edge of the large chuck 1, and a number of second card slots 21 are equidistantly arranged on the circular edge of the small chuck 2. The positions of these card slots correspond to each other to ensure the symmetry and stability of the structure. The support mechanism 4 includes rotating columns 41 in the first card slots 11 and the second card slots 21. A first rotating block 42 is connected to the rotating column 41, and support bars 43 are arranged on these first rotating blocks 42. The function of the support bars 43 is to stretch the soft light cloth, so that the light is evenly dispersed through the soft light cloth, reducing the strong light directly irradiating on the object to be photographed, so as to obtain a softer lighting effect. The adjusting mechanism 5 is composed of an upper adjusting block 51 fixedly connected to the large chuck 1 and a lower telescopic mechanism 52 fixedly connected to the small chuck 2. Through the cooperation of the lower telescopic mechanism 52 and the upper adjusting block 51, the distance between the large chuck 1 and the small chuck 2 can be adjusted. This adjustment mechanism enables the user to adjust the degree of stretching of the soft light cloth according to needs, so as to change the diffusion range and intensity of the light and adapt to different shooting environments and requirements. Generally speaking, the design of this portable spherical photographic soft light box allows the user to adjust the tension of the soft light cloth through the adjusting mechanism 5 and keep the soft light cloth stable through the support mechanism 4, so as to achieve uniform diffusion of the light source and achieve an ideal soft light effect.

[0030] Refer to Figures 1-9 : The lower telescopic mechanism 52 includes a first telescopic component 521, a first threaded component 522, a second telescopic component 523, a second threaded component 524, a third telescopic component 525, a third threaded component 526 and a base 527. The first telescopic component 521 is fixedly connected to the upper adjusting block 51. The first telescopic component 521 is arranged in the second telescopic component 523, the second telescopic component 523 is arranged in the third telescopic component 525, the third telescopic component 525 is arranged in the base 527, the first threaded component 522 is arranged in the first telescopic component 521, the second threaded component 524 is arranged in the first threaded component 522, and the third threaded component 526 is arranged in the second threaded component 524.

[0031] The telescopic mechanism consists of three main parts: the first telescopic component 521, the second telescopic component 523, and the third telescopic component 525. They are nested in sequence, that is, the first telescopic component 521 is arranged inside the second telescopic component 523, the second telescopic component 523 is arranged inside the third telescopic component 525, and the third telescopic component 525 is arranged inside the base 527. Such a design allows the overall length to be adjusted by the relative movement of the telescopic components, thereby changing the distance between the large chuck 1 and the small chuck 2. Each telescopic component is equipped with a corresponding threaded component, that is, the first threaded component 522 is arranged inside the first telescopic component 521, the second threaded component 524 is arranged inside the first threaded component 522, and the third threaded component 526 is arranged inside the second threaded component 524. The arrangement of these threaded components allows the extension or contraction of the telescopic components to be controlled by rotation, achieving precise adjustment of the spacing. When it is necessary to increase the distance between the large chuck 1 and the small chuck 2, the corresponding threaded component can be rotated to make the inner telescopic component extend outwards. On the contrary, when it is necessary to reduce the spacing, rotating the threaded component will cause the telescopic component to contract inwards. The combined use of such threads and telescopic components provides a simple and efficient way to adjust the size and shape of the softbox to meet different shooting requirements.

[0032] Refer to Figures 1-9 : The inner wall of the first telescopic component 521 is provided with internal threads, the outer wall of the first telescopic component 521 is fixedly connected with a first limiting block 5211, the outer wall of the first threaded component 522 is provided with external threads, the inner wall of the second telescopic component 523 is provided with a first limiting groove 5231. When the first threaded component 522 rotates, the first telescopic component 521 moves along the long side direction of the first limiting groove 5231 under the cooperation of the first limiting block 5211 and the first limiting groove 5231.

[0033] The inner wall of the first telescopic component 521 is equipped with internal threads, enabling it to cooperate with the first threaded component 522 having corresponding external threads. When the first threaded component 522 rotates, due to the meshing of the threads on the inner and outer walls, the first telescopic component 521 can move along the first threaded component 522. To control this movement and ensure precise adjustment, a first limiting block 5211 is fixedly connected to the outer wall of the first telescopic component 521. At the same time, a first limiting groove 5231 is provided on the inner wall of the second telescopic component 523. This design allows the first telescopic component 521 to move along the long side direction of the first limiting groove 5231 under the cooperation of the first limiting block 5211 and the first limiting groove 5231. When the first threaded component 522 rotates, it drives the first telescopic component 521 to extend or retract. Due to the cooperation of the first limiting block 5211 and the first limiting groove 5231, the movement range of the first telescopic component 521 can be restricted, preventing it from over-telescoping, thereby ensuring the stable operation of the adjustment mechanism 5 of the softbox and avoiding structural damage or functional failure caused by over-adjustment. In this way, users can precisely adjust the size and shape of the softbox to adapt to different shooting requirements while maintaining the stability and safety of the adjustment process.

[0034] Refer to Figures 1-9 : A first inner lifting block 5232 is provided at the bottom of the second telescopic component 523. The inner wall of the first inner lifting block 5232 is provided with internal threads. A second limiting block 5233 is provided on the outer wall of the second telescopic component 523. The outer wall of the second threaded component 524 is provided with external threads. A second limiting groove 5251 is provided on the inner wall of the third telescopic component 525. Through the first inner lifting block 5232, the first threaded component 522 and the second telescopic component 523 move synchronously along the axial direction of the first threaded component 522. When the second threaded component 524 rotates, it drives the second telescopic component 523 to move along the long side direction of the second limiting groove 5251.

[0035] The first inner lifting block 5232 is not only a component at the bottom of the second telescopic component 523, but also fixedly connected to the second telescopic component 523 to ensure their synchronous movement. The inner wall of the first inner lifting block 5232 is provided with internal threads, and these internal threads mesh with the external threads of the second threaded component 524. When the second threaded component 524 rotates, due to the meshing between the external threads and the internal threads on the inner wall of the first inner lifting block 5232, the first inner lifting block 5232 drives the second telescopic component 523 to perform synchronous telescopic movement along its axis. A second limiting block 5233 is provided on the outer wall of the second telescopic component 523, which works together with the fixed connection of the first inner lifting block 5232 to ensure the stability of the second telescopic component 523 during the telescopic process, limit its movement range, and prevent excessive telescoping. At the same time, a second limiting groove 5251 is provided on the inner wall of the third telescopic component 525, and this limiting groove cooperates with the second limiting block 5233 to jointly control the movement of the second telescopic component 523 along the long side direction of the second limiting groove 5251. This

[0036] cooperation ensures that the second telescopic component 523 can move smoothly on a predetermined path, further adjusting the size of the soft light box. Through this design, the adjusting mechanism 5 of the soft light box can achieve precise and stable size adjustment to meet different shooting requirements. The fixed synchronous movement of the first inner lifting block 5232 and the second telescopic component 523, as well as the driving effect of the second threaded component 524, make the entire adjustment process flexible and reliable.

[0037] Refer to Figures 1-9 : A second inner lifting block 5252 is provided at the bottom of the third telescopic component 525. The inner wall of the second inner lifting block 5252 is provided with internal threads, and the outer wall of the third threaded component 526 is provided with external threads. A third limiting block 5253 is provided on the outer wall of the third telescopic component 525, and a third limiting groove 5271 is provided on the inner wall of the base 527. The second inner lifting block 5252 and the second threaded component 524 move synchronously along the axial direction of the second inner lifting block 5252. When the third threaded component 526 rotates, the third telescopic component 525 moves along the long side direction of the third limiting groove 5271.

[0038] The bottom of the third telescopic component 525 is installed with a second inner lifting block 5252, and the inner wall of the second inner lifting block 5252 is machined with internal threads. The internal threads are engaged with the external threads of the third threaded component 526, so that when the third threaded component 526 rotates, the second inner lifting block 5252 can move in the axial direction according to the engagement relationship between the internal threads and the external threads. The second inner lifting block 5252 is fixedly connected to the third threaded component 526 to ensure that they can move synchronously. This design of synchronous movement allows the entire mechanism to maintain consistency during adjustment, improving the accuracy and stability of adjustment. A third limit block 5253 is installed on the outer wall of the third telescopic component 525, which cooperates with the third limit groove 5271 on the inner wall of the base 527. This design ensures that the third telescopic component 525 can move along a specific direction, that is, the long side direction of the third limit groove 5271, while restricting its movement range and preventing structural damage or instability that may be caused by excessive telescoping. When the third threaded component 526 rotates, it drives the second inner lifting block 5252 to move along the internal threads through the external threads. Since the second inner lifting block 5252 is connected to the third telescopic component 525, the third telescopic component 525 will also move along the long side direction of the third limit groove 5271. Such movement adjusts the size and shape of the soft light box, enabling the soft light box to be adjusted according to different shooting requirements. Overall, the design of this adjustment mechanism 5 achieves precise adjustment of the size of the soft light box, while maintaining the stability and safety of the adjustment process, meeting the specific requirements for soft light effects in different shooting environments.

[0039] Refer to Figures 1-9 : A first moving block 5221 is provided inside the first threaded component 522, a first moving groove 5241 is provided on the outer wall of the second threaded component 524, a second moving block 5242 is provided on the inner wall of the second threaded component 524, and a second moving groove 5263 is provided on the outer wall of the third threaded component 526. Through the cooperation of the first moving block 5221 and the first moving groove 5241, and the cooperation of the second moving block 5242 and the second moving groove 5263, while the first threaded component 522, the second threaded component 524, and the third threaded component 526 rotate synchronously, the second threaded component 524 and the third threaded component 526 move in the axial direction of the first threaded component 522.

[0040] The interior of the first threaded component 522 is designed with a first moving block 5221, which enables the first threaded component 522 to not only rotate but also move in the axial direction. The first moving block 5221 cooperates with a first moving groove 5241 provided on the outer wall of the second threaded component 524, allowing the second threaded component 524 to move in the axial direction of the first threaded component 522 while rotating. Similarly, a second moving block 5242 is provided on the inner wall of the second threaded component 524, and the second moving block 5242 cooperates with a second moving groove 5263 on the outer wall of the third threaded component 526, enabling the third threaded component 526 to also move in the axial direction of the second threaded component 524 while rotating. This design achieves the synchronous rotation and axial movement of the three threaded components - the first threaded component 522, the second threaded component 524, and the third threaded component 526. When the first threaded component 522 rotates, the movement of the first moving block 5221 in the first moving groove 5241 drives the second threaded component 524 to rotate and move axially; similarly, the rotation of the second threaded component 524 drives the third threaded component 526 to rotate and move axially through the movement of the second moving block 5242 in the second moving groove 5263.

[0041] Refer to Figures 1-9 : A connecting post 5261 is provided at the bottom of the third threaded component 526. The connecting post 5261 is fixedly connected with a second rotating block 5262. A first fixing hole 52621 is provided on the second rotating block 5262, and a second fixing hole 5272 is provided on the base 527. When the first fixing hole 52621 coincides with the second fixing hole 5272, the limiting block 6 can be inserted to fix the adjusting mechanism 5.

[0042] The bottom of the third threaded component 526 is designed with a connecting post 5261, and a second rotating block 5262 is fixedly connected to this connecting post 5261. A first fixing hole 52621 is provided on the second rotating block 5262, and a second fixing hole 5272 is correspondingly provided on the base 527. When the first fixing hole 52621 on the second rotating block 5262 aligns and coincides with the second fixing hole 5272 on the base 527, a limiting block 6 can be inserted into these two fixing holes. The inserted limiting block 6 plays a locking role. Once the limiting block 6 is inserted and fixed, it will limit the further movement of the adjusting mechanism 5, thereby locking the current size and shape of the soft light box. This design provides a simple and effective method to fix the adjustment state of the soft light box, ensuring the stability of the soft light box during the shooting process, preventing the movement of the adjusting mechanism 5 caused by accidental touch or other reasons, and affecting the shooting effect. Through the alignment of the first fixing hole 52621 on the second rotating block 5262 and the second fixing hole 5272 on the base 527 and the insertion of the limiting block 6, the rapid fixing and locking of the entire adjusting mechanism 5 are achieved, making the adjustment process both flexible and safe, meeting the requirements for the stability of the soft light box in different shooting scenarios.

[0043] Refer to Figures 1-9 : The inner wall of the first threaded component 522 is provided with a first synchronous lifting groove 5222, the outer wall of the first inner lifting block 5232 is provided with a second synchronous lifting groove 52321, the inner wall of the second threaded component 524 is provided with a third synchronous lifting groove 5243, the outer wall of the second inner lifting block 5252 is provided with a fourth synchronous lifting groove 52521, a limiting ring 7 is provided between the first synchronous lifting groove 5222 and the second synchronous lifting groove 52321, and a limiting ring 7 is provided between the third synchronous lifting groove 5243 and the fourth synchronous lifting groove 52521. Through the setting of the limiting ring 7, the first threaded component 522 and the second telescopic component 523, and the second threaded component 524 and the third telescopic component 525 move synchronously along the axis of the third threaded component 526.

[0044] The inner wall of the first threaded component 522 is designed with a first synchronous lifting groove 5222. Correspondingly, a second synchronous lifting groove 52321 is provided on the outer wall of the first inner lifting block 5232. This design allows the first threaded component 522 and the first inner lifting block 5232 to cooperate with each other through the synchronous lifting grooves to achieve synchronous movement. Similarly, the inner wall of the second threaded component 524 is provided with a third synchronous lifting groove 5243, and the outer wall of the second inner lifting block 5252 is provided with a fourth synchronous lifting groove 52521. The second threaded component 524 and the second inner lifting block 5252 can also achieve synchronous movement through these synchronous lifting grooves. To ensure that these components can move synchronously along the axial direction of the third threaded component 526, limiting rings 7 are provided between the first synchronous lifting groove 5222 and the second synchronous lifting groove 52321, and between the third synchronous lifting groove 5243 and the fourth synchronous lifting groove 52521. The function of the limiting ring 7 is to synchronously connect the first threaded component 522 with the second telescopic component 523, and the second threaded component 524 with the third telescopic component 525, ensuring that they can move in a coordinated manner during the adjustment process. When the third threaded component 526 rotates, due to the connection function of the limiting ring 7, the first threaded component 522 and the second threaded component 524 will rotate correspondingly, and due to the cooperation of the synchronous lifting grooves, the first inner lifting block 5232 and the second inner lifting block 5252 will be driven to move synchronously along the axial direction. This synchronous movement mechanism enables the adjustment mechanism 5 of the entire soft light box to be precisely controlled, realizing fine adjustment of the size and shape of the soft light box to adapt to different shooting requirements. Through the setting of the limiting ring 7, the movement of the entire adjustment mechanism 5 is more stable and reliable, ensuring the accuracy of the adjustment process and the stability of the soft light box during shooting. This design provides an efficient and flexible adjustment method, enabling users to quickly adjust the soft light box according to needs to achieve the ideal light effect.
