Description

Technical Field

[0001] The utility model relates to the field of photographic accessories, in particular to a chuck mechanism. Background Art

[0002] Softboxes are a common photography accessory, and their use is growing increasingly widespread with advancements in photography technology and the economy. Traditional softboxes have separate release switches for each rib, requiring individual releases when storing. This is time-consuming, labor-intensive, and inconvenient. To address this issue, softboxes that can be opened and closed with a single button are now entering the market.

[0003] For example, a chuck assembly and a softbox having the chuck assembly disclosed in a prior patent (application number CN202321575420.3) include a carrier plate and a rotating plate. The carrier plate has a plurality of mounting portions spaced apart along the circumference of the carrier plate. Each mounting portion is provided with an umbrella rib rotatably connected to the carrier plate. The umbrella rib has a fixed end and a free end relative to the carrier plate. The umbrella rib can be pitched and swung relative to the carrier plate to close or open the free end. The rotating plate is rotatably provided on the carrier plate around the central axis of the carrier plate. The outer side wall of the rotating plate is provided with a guide member. The fixed end is embedded in the guide member. The rotating plate can rotate relative to the carrier plate and drive the fixed end to slide in the guide member to close or open the free end. Since the rotating plate can directly drive the umbrella ribs to open or close through the guide member, compared with the existing chuck assembly that needs to drive the umbrella ribs to open or close through an intermediate drive member, the structure is compact, the assembly is simpler, and the cost is reduced. However, when a softbox is used in conjunction with a light source, the light source shines into the softbox, which causes a large amount of heat to concentrate inside the softbox, thereby causing the temperature to be too high and reducing its service life.

[0040] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0041] See also Figure 1-7 , this embodiment provides a chuck mechanism, comprising:

[0042] A support assembly for mounting the diffuser 6, wherein a light passage 11 connected to the diffuser 6 is provided in the support assembly;

[0043] Mounting tube 2 has a mounting channel 21 defined therein. One end of mounting tube 2 is connected to the support assembly, and one end of mounting channel 21 is connected to light passage 11. A mounting position 22 for mounting on external light source device 7 is defined at the other end of mounting channel 21, which extends through the other end of mounting tube 2 to form a light inlet 24. A heat dissipation vent 23 extending from mounting channel 21 is also defined on the outside of mounting tube 2. Mounting tube 2 is sleeved onto external light source device 7 via light inlet 24.

[0044] In this embodiment, there are multiple heat dissipation openings 23 , and the multiple heat dissipation openings 23 are annularly arranged outside the installation passage.

[0045] In this embodiment, the support assembly includes:

[0046] The connecting tube 1 and the light passage 11 are provided in the connecting tube 1, and one end of the connecting tube 1 is connected to one end of the mounting tube 2;

[0047] A movable ring 3 is slidably sleeved on the outside of the connecting tube 1, and a first disassembly structure is provided on the movable ring 3. A second disassembly structure 5 is provided on the connecting tube 1 or the installation tube 2. The first disassembly structure and the second disassembly structure 5 are detachably connected;

The supporting elastic rod 41 is hingedly set on the movable ring 3, and the two ends of the connecting rod 42 are respectively hinged to one end of the mounting tube 2 and the supporting elastic rod 41.

[0049] Specifically, the movable ring 3 can slide on the outside of the connecting tube 1, and when the movable ring 3 slides toward the mounting tube 2, the first disassembly and assembly structure on the movable ring 3 approaches the second disassembly and assembly structure 5, thereby realizing the clamping of the first disassembly and assembly structure and the second disassembly and assembly structure 5; and at this time, driven by the relative movement of the movable ring 3 and the connecting tube 1, the connecting rod 42 will support the elastic rod 41 outward to support the soft light cover 6 installed on the outside of the elastic rod 41; and when the first disassembly and assembly structure and the second disassembly and assembly structure 5 are disengaged, and the movable ring 3 slides in the direction away from the mounting tube 2, driven by the relative movement of the movable ring 3 and the connecting tube 1, the connecting rod 42 and the supporting elastic rod 41 are closed to drive the soft light cover 6 installed on the outside of the supporting elastic rod 41 to retract.

[0050] In this embodiment, first disassembly and assembly structures are provided on both sides of the movable ring 3 , and second disassembly and assembly structures 5 are provided on both sides of the connecting tube 1 or both sides of the installation tube 2 .

[0051] In this embodiment, the first disassembly structure includes a first buckle 31; the second disassembly structure 5 includes:

[0052] A second buckle 51 corresponding to the position of the first buckle 31;

[0053] An elastic member that elastically engages the second clip and the first clip 31, and the elastic member is preferably a spring;

[0054] A triggering member 52 is used to control the second buckle 51 to compress the elastic member to separate the first buckle 31 from the second buckle 51 .

[0055] Specifically, when the first buckle 31 and the second buckle 51 are engaged, the first buckle 31 is moved close to the second buckle 51 through the relative movement of the movable ring 3 and the connecting tube 1, and the second buckle 51 is controlled to compress the elastic part by abutting, and finally the first buckle 31 and the second buckle 51 are engaged under the rebound of the elastic part; when the first buckle 31 and the second buckle 51 need to be disengaged, the second buckle 51 is controlled by the trigger part 52 to compress the elastic part, so that the first buckle 31 and the second buckle 51 are disengaged.

[0056] In this embodiment, one end of the connecting tube 1 extends into the installation channel 21 to be socketed with one end of the installation tube 2. A clamping seat 25 is provided on the side of the installation tube 2. A clamping groove 251 is provided in the clamping seat 25. The clamping groove 251 is connected to the installation channel 21. The second clip 51 is movably provided in the clamping groove 251. The two ends of the first elastic member are respectively connected to the outer side of one end of the connecting tube 1 and the second clip 51. One end of the trigger member 52 is connected to the second clip 51, and the other end of the trigger member 52 is movably passed through the clamping seat 25 to be exposed to the outside.

One end of the two trigger connecting portions 522 is respectively fixed at both sides of one end of the trigger pressing portion 521, and the other ends of the two trigger connecting portions 522 are respectively fixed to the second snap buckle 51. The second snap buckle 51, the trigger pressing portion 521 and the two trigger connecting portions 522 are collectively formed to form a snap-fit ​​hole 523, and the first snap buckle 31 corresponds to the position of the snap-fit ​​hole 523.

[0058] In this embodiment, the first buckle 31 is provided with a first abutting bevel 311, and the second buckle 51 is provided with a second abutting bevel 511, and the first abutting bevel 311 and the second abutting bevel 511 correspond to each other. The cooperation of the first abutting bevel 311 and the second abutting bevel 511 can make the process of the first buckle 31 being inserted into the engaging hole 523 and engaging with the second buckle 51 smoother.

[0059] In this embodiment, the second buckle 51 is provided with an anti-slip portion 512 for abutting against the side surface of the installation channel 21 .

[0060] In this embodiment, a sliding protrusion 32 for controlling the movement of the movable ring 3 is fixed on the outer side of the movable ring 3 .

[0061] In this embodiment, a connecting end 12 corresponding to the external light source device 7 is provided at one end of the connecting tube 1. A light shielding ring 13 is provided around the outside of the connecting end 12 to block the avoidance gap 15 between the connecting end 12 and the external light source device 7, and a heat dissipation gap 14 is formed between the light shielding ring 13 and the connecting end 12. It can be seen that when the external light source device 7 is installed on the mounting tube 2, its end extends into the mounting channel 21 to align with the connecting end 12, and its light can be irradiated to the light passage 11 through the connecting end 12. At this time, there is an avoidance gap 15 between the end of the external light source device 7 and the connecting end 12. The avoidance gap 15 is used to prevent the end of the external light source device 7 from colliding with the connecting end 12 during installation, and at the same time, heat can be dissipated through the avoidance gap 15. The setting of the light shielding ring 13 can not only block the avoidance gap 15, but also dissipate heat through the avoidance gap 15, the heat dissipation gap 14, the mounting channel 21, and the heat dissipation port 23 in sequence.

[0062] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
