Description

Technical Field

[0001] This invention relates to the technical field of film and television lighting equipment, and more specifically, to a coil device and film and television lighting equipment. Background Technology

[0002] Film and television lighting, as core lighting equipment in film and television shooting, stage performances, and studio lighting, requires power cables for power transmission during actual use. To facilitate cable management, neat wiring, and rapid on-site wiring, automatic cable reel devices are commonly used in the industry. Existing cable reel devices for film and television lighting mostly employ a spring-loaded automatic cable reel structure, relying on the spring force to pull out and automatically retract the cable. While this achieves automatic cable retrieval, it has significant technical shortcomings in practical applications.

[0003] Firstly, in the existing cable reel, the rotation speed of the reel cannot be adaptively adjusted during the cable pulling out and elastic retraction process. When the cable is pulled out quickly, the cable speed is prone to being too fast, and the cable may swing and drift, which can easily cause the cable to bend, wear, and be damaged by impact, and even cause on-site wiring safety hazards. During the automatic cable retraction stage, the coil spring continuously drives the reel to rotate at high speed, and the retraction speed is uncontrolled. This can easily lead to problems such as the cable winding back rapidly, knotting and tangling, and pulling and bouncing. This not only damages the cable insulation layer and internal wire core, but also shortens the overall service life of the cable and the reel.

[0004] Secondly, traditional reels lack a speed-adaptive damping structure, making it impossible to dynamically adjust the frictional deceleration force according to the real-time rotation speed of the reel. At high speeds, there is no effective braking and deceleration effect, and at low speeds, the damping force is fixed when finely adjusting the wire feeding and reeling. This makes it difficult to meet the needs of precise wiring and fixed-point stopping in film and television lighting, resulting in poor operation smoothness and usage stability.

[0005] Third, conventional reel deceleration structures mostly adopt constant resistance designs such as fixed damping plates and damping sleeves. The damping magnitude cannot adapt to changes in rotational speed. After long-term use, damping wear failure and deceleration effect are likely to occur, resulting in high maintenance costs. Furthermore, they cannot adapt to the winding and unwinding needs of film and television lighting cables of different lengths and diameters, lacking versatility and durability. Summary of the Invention

[0006] The purpose of this invention is to provide a reel device and film and television lighting equipment to solve the technical problems of existing film and television lighting reel devices, such as uncontrollable rotation speed, easy swinging and knotting of the reel during winding and unwinding, lack of adaptive deceleration function, poor stability and versatility.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: In a first aspect, a spool device is provided, comprising: A housing, a coil assembly disposed inside the housing, and a speed reduction assembly connected to the coil assembly; The housing is defined with a rotation axis X; The coil assembly includes a coil rotatable about the rotation axis X, a cable wound on the coil, and a retraction elastic member connecting the housing and the coil. The coil rotates about a first direction while overcoming the elastic force of the retraction elastic member to release the cable. The coil rotates about a second direction opposite to the first direction and retracts the cable under the elastic force of the retraction elastic member. The deceleration assembly includes a deceleration housing fixedly connected to the housing, a deceleration wheel disposed inside the deceleration housing, and a centrifugal structure movably connected to the deceleration wheel. The deceleration wheel is fixedly connected to the spool and can rotate synchronously. The centrifugal structure performs centrifugal motion under the drive of the rotation of the deceleration wheel and abuts against the deceleration housing to generate a frictional force that drives the spool to decelerate. The faster the rotation speed of the deceleration wheel, the greater the force exerted by the centrifugal structure on the deceleration housing, and the greater the frictional force on the spool. The slower the rotation speed of the deceleration wheel, the smaller the force exerted by the centrifugal structure on the deceleration housing, and the smaller the frictional force on the spool.

[0008] By adopting the above technical solution, the release and retrieval of cables can be made stable and controllable, avoiding problems such as swinging, drifting, bending and wear when the cable is pulled out quickly, and rapid rewinding, knotting, tangling, pulling and bouncing when the cable is retrieved. This effectively protects the cable and the reel assembly and extends their service life. At the same time, the centrifugal structure can adaptively adjust the deceleration friction according to the reel speed, adapting to the cable release and retrieval needs at different speeds, improving the smoothness of operation and the stability of use. Moreover, the structure is compact and can be adapted to the use scenarios of equipment such as film and television lights, with strong versatility and durability.

[0033] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0034] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be located directly on or indirectly on the other component. When a component is referred to as "connected to" another component, it can be directly or indirectly connected to the other component.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating relative importance or the number of technical features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified. The specific implementation of this invention will be described in more detail below with reference to specific embodiments: like Figure 1 and Figure 2As shown, an embodiment of the present invention provides a coil device, comprising: Housing 1, coil assembly 2 disposed inside housing 1, and speed reduction assembly 3 connected to coil assembly 2; Among them, shell 1 is defined with a rotation axis X; like Figures 3 to 5 As shown, the coil assembly 2 includes a coil 21 that can rotate about a rotation axis X, a cable 22 wound on the coil 21, and a retraction elastic member 23 connecting the housing 1 and the coil 21. The coil 21 rotates about a first direction while overcoming the elastic force of the retraction elastic member 23 to release the cable 22. The coil 21 rotates about a second direction opposite to the first direction and retracts the cable 22 under the elastic force of the retraction elastic member 23. The deceleration assembly 3 includes a deceleration housing 30 fixedly connected to the housing 1, a deceleration wheel 31 disposed inside the deceleration housing 30, and a centrifugal structure 32 movably connected to the deceleration wheel 31. The deceleration wheel 31 is fixedly connected to the coil 21 and can rotate synchronously. The centrifugal structure 32 performs centrifugal motion under the drive of the rotation of the deceleration wheel 31 and abuts against the deceleration housing 30 to generate a frictional force that drives the coil 21 to decelerate. The faster the rotation speed of the deceleration wheel 31, the greater the force exerted by the centrifugal structure 32 on the deceleration housing 30, and the greater the frictional force on the coil 21. The slower the rotation speed of the deceleration wheel 31, the smaller the force exerted by the centrifugal structure 32 on the deceleration housing 30, and the smaller the frictional force on the coil 21.

[0037] Please refer to the following: Figure 6 The specific structural components of the coil device are as follows: it includes a housing 1, a coil assembly 2, and a reduction assembly 3. The housing 1 defines a rotation axis X. The coil assembly 2 is located inside the housing 1. The reduction assembly 3 is connected to the coil assembly 2. The coil assembly 2 specifically consists of a coil 21 that can rotate around the rotation axis X, a cable 22 wound on the coil 21, and a retraction elastic element 23 connecting the housing 1 and the coil 21. The reduction assembly 3 specifically consists of a reduction housing 30 fixedly connected to the housing 1, a reduction wheel 31 located inside the reduction housing 30, and a centrifugal structure 32 movably connected to the reduction wheel 31. The reduction wheel 31 is fixedly connected to the coil 21 and can rotate synchronously.

[0038] Its working principle is as follows: When the cable 22 needs to be released, the coil 21 rotates around the first direction, overcoming the elastic force of the retraction elastic element 23 to pull out and release the cable 22; when the cable 22 needs to be retrieved, the coil 21 rotates around the second direction opposite to the first direction, and the cable 22 is retracted and retrieved under the action of the elastic force of the retraction elastic element 23; when the release or retrieval of the cable 22 causes the coil 21 to rotate, the reduction wheel 31 fixedly connected to the coil 21 rotates synchronously, driving the centrifugal structure 32 movably connected to it to perform centrifugal motion. During the movement of the centrifugal structure 32, it abuts against the reduction housing 30, thereby generating a frictional force that drives the coil 21 to decelerate. The rotation speed of the reduction wheel 31 is positively correlated with the force exerted by the centrifugal structure 32 on the reduction housing 30. That is, the faster the rotation speed of the reduction wheel 31, the greater the force exerted by the centrifugal structure 32, the greater the frictional force on the coil 21, and the more obvious the deceleration effect. The slower the rotation speed of the reduction wheel 31, the smaller the force exerted by the centrifugal structure 32, the smaller the frictional force on the coil 21, and the smoother the deceleration effect.

[0039] By adopting the above technical solution, the release and retrieval of cable 22 can be made stable and controllable, avoiding problems such as swinging, drifting, bending and wear when cable 22 is pulled out quickly, and rapid rewinding, knotting, entanglement, pulling and bouncing when cable 22 is retrieved. This effectively protects cable 22 and reel assembly 2 and extends their service life. At the same time, the centrifugal structure 32 can adaptively adjust the deceleration friction according to the speed of reel 21, adapting to the cable release and retrieval requirements at different speeds, improving the smoothness of operation and the stability of use. Moreover, the structure is compact and can be adapted to the use scenarios of equipment such as film and television lights, with strong versatility and durability.

[0040] like Figure 7 As shown, in one embodiment, the deceleration assembly 3 further includes a guide engagement assembly 34 connecting the deceleration wheel 31 and the centrifugal structure 32. The guide engagement assembly 34 includes a guide boss 341 and a guide groove 342 that is clearance-fitted with the guide boss 341. The guide boss 341 is disposed on one of the deceleration wheel 31 and the centrifugal structure 32, and the guide groove 342 is formed on the other of the deceleration wheel 31 and the centrifugal structure 32.

[0041] The deceleration assembly 3 of the reel device further includes a guide fitting assembly 34 connecting the deceleration wheel 31 and the centrifugal structure 32, based on the original structure. The specific structure of the guide fitting assembly 34 is as follows: the guide fitting assembly 34 is composed of a guide boss 341 and a guide groove 342. The guide boss 341 and the guide groove 342 are in a clearance fit state. The guide boss 341 is set on either the deceleration wheel 31 or the centrifugal structure 32, and the guide groove 342 is correspondingly opened on the other component of the deceleration wheel 31 and the centrifugal structure 32. That is, if the guide boss 341 is set on the deceleration wheel 31, the guide groove 342 is opened on the centrifugal structure 32, and if the guide boss 341 is set on the centrifugal structure 32, the guide groove 342 is opened on the deceleration wheel 31. The guide fitting assembly 34, together with the deceleration housing 30, the deceleration wheel 31, and the centrifugal structure 32, constitutes the complete deceleration assembly 3. The deceleration wheel 31 is still fixedly connected to the reel 21 and can rotate synchronously.

[0042] Its working principle is as follows: When the reel 21 rotates around the first direction to release the cable 22 or rotates around the second direction to retract the cable 22, the reduction wheel 31, which is fixedly connected to the reel 21, rotates synchronously. At this time, the reduction wheel 31 drives the centrifugal structure 32 to move through the guide fitting assembly 34. Specifically, the guide boss 341 and the guide groove 342 achieve guidance and limitation through clearance fit, so that the centrifugal structure 32 can make centrifugal motion smoothly along the guide direction under the drive of the reduction wheel 31, avoiding deviation, jamming or other situations during the movement of the centrifugal structure 32. When the centrifugal structure 32 makes centrifugal motion, it abuts against the reduction housing 30 to generate friction force that drives the reel 21 to decelerate. The faster the speed of the reduction wheel 31, the greater the force exerted by the centrifugal structure 32 on the reduction housing 30, and the greater the friction force on the reel 21. The slower the speed of the reduction wheel 31, the smaller the force exerted by the centrifugal structure 32 on the reduction housing 30, and the smaller the friction force on the reel 21. At the same time, the guide fitting assembly 34 can ensure that the centrifugal motion of the centrifugal structure 32 always proceeds in the preset direction, ensuring the stable performance of the deceleration effect.

[0043] By adopting the above technical solution, not only is the original deceleration component 3 able to adaptively adjust the deceleration friction force according to the rotation speed of the reel 21, achieving a smooth and controllable winding and unwinding effect, but also the guiding and limiting function of the guide fitting component 34 prevents the centrifugal structure 32 from deviating or jamming during movement, further improving the stability and reliability of the deceleration component 3 and ensuring the consistency of the deceleration effect. At the same time, the clearance fit design can reduce the frictional loss between the guide boss 341 and the guide groove 342, extend the service life of the deceleration component 3, and thus improve the durability and stability of the entire reel device, better adapting to the usage requirements of equipment such as film and television lights.

[0044] In one embodiment, the guide fitting assembly 34 includes a guide boss 341 and a guide groove 342 that is clearance-fitted with the guide boss 341. The height direction of the guide boss 341 and the groove depth direction of the guide groove 342 are parallel to the centrifugal direction.

[0045] The guide engagement component 34 in the deceleration assembly 3 of the spool device has the following specific structural composition: the guide engagement component 34 includes a guide boss 341 and a guide groove 342. The guide boss 341 and the guide groove 342 are in clearance fit, and the height direction of the guide boss 341 and the groove depth direction of the guide groove 342 are both parallel to the centrifugal direction. The guide engagement component 34 is used to guide the centrifugal structure 32 to move along the centrifugal direction and the centripetal direction. It, together with the deceleration wheel 31, the centrifugal structure 32, and the deceleration housing 30, constitutes the complete deceleration assembly 3. The guide boss 341 is provided on one of the deceleration wheel 31 and the centrifugal structure 32, and the guide groove 342 is opened on the other of the deceleration wheel 31 and the centrifugal structure 32. The deceleration wheel 31 is still fixedly connected to the spool 21 and can rotate synchronously.

[0046] Its working principle is as follows: When the reel 21 rotates around the first direction to release the cable 22 or rotates around the second direction to retrieve the cable 22, the reduction wheel 31, which is fixedly connected to the reel 21, rotates synchronously. The reduction wheel 31 drives the centrifugal structure 32 to move through the gap fit between the guide boss 341 and the guide groove 342. Since the height direction of the guide boss 341 and the groove depth direction of the guide groove 342 are both parallel to the centrifugal direction, under the guidance of the guide fitting assembly 34, the centrifugal structure 32 can smoothly perform centrifugal motion along the centrifugal direction and smoothly reset along the centripetal direction, effectively avoiding deviation, jamming or other issues during the movement of the centrifugal structure 32. In cases of deviation in motion direction, when the centrifugal structure 32 performs centrifugal motion, it comes into contact with the deceleration housing 30, generating a frictional force that drives the coil 21 to decelerate. The faster the speed of the deceleration wheel 31, the greater the force exerted by the centrifugal structure 32 on the deceleration housing 30, and the greater the frictional force on the coil 21. The slower the speed of the deceleration wheel 31, the smaller the force exerted by the centrifugal structure 32 on the deceleration housing 30, and the smaller the frictional force on the coil 21. At the same time, the guide assembly 34 ensures that the centrifugal motion and centripetal reset of the centrifugal structure 32 always proceed along the preset centrifugal and centripetal directions by limiting the motion direction, thus ensuring the stable and continuous performance of the deceleration effect.

[0047] By adopting the above technical solution, not only is the guiding and limiting function of the original guiding and fitting component 34 and the adaptive speed adjustment and deceleration effect of the deceleration component 3 retained, but also the centrifugal structure 32 is precisely guided to move in the centrifugal and centripetal directions by limiting the height direction of the guide boss 341 and the groove depth direction of the guide groove 342 to be parallel to the centrifugal direction. This further improves the stability and accuracy of the movement of the centrifugal structure 32, completely avoiding problems such as jamming and unstable deceleration effect caused by deviation in the movement direction. At the same time, the clearance fit direction limitation design can reduce the wear of the guiding and fitting component 34 and extend its service life, thereby improving the working reliability and durability of the entire deceleration component 3 and the wire reel device, ensuring that the cable 22 winding and unwinding process is stable and controllable, and better adapting to the usage requirements of equipment such as film and television lights.

[0048] In one embodiment, the deceleration assembly 3 further includes a centripetal elastic element 33 connecting the deceleration wheel 31 and the centrifugal structure 32. The centripetal elastic element 33 is used to limit the direction and position of movement of the centrifugal structure 32, so that the centrifugal structure 32 performs centripetal movement.

[0049] The deceleration assembly 3 of the reel device further includes a centripetal elastic element 33 connecting the deceleration wheel 31 and the centrifugal structure 32, based on the original structure. Specifically, the deceleration assembly 3 includes a deceleration housing 30 fixedly connected to the housing 1, a deceleration wheel 31 disposed inside the deceleration housing 30, a centrifugal structure 32 movably connected to the deceleration wheel 31, and a centrifugal elastic element 33 connecting the deceleration wheel 31 and the centrifugal structure 32. The deceleration assembly 3 also includes a guide fitting assembly 34 connecting the deceleration wheel 31 and the centrifugal structure 32. The guide fitting assembly 34 includes a guide boss 341 and a guide groove 342 that is clearance-fitted with the guide boss 341. The guide boss 341 is disposed on the deceleration wheel 31 and the centrifugal structure 32. One of the centrifugal structures 32 has a guide groove 342 formed on the other of the reduction wheel 31 and the centrifugal structure 32. The centrifugal elastic member 33 is used to limit the direction and position of the centrifugal structure 32, so that the centrifugal structure 32 moves centripetally. The core function of the centrifugal elastic member 33 is to drive the centrifugal structure 32 to move centripetally. The reduction wheel 31 is fixedly connected to the coil 21 and can rotate synchronously. All components work together to form a complete reduction assembly 3. The coil assembly 2 still includes the coil 21 that can rotate around the rotation axis X defined by the housing 1, the cable 22 wound on the coil 21, and the recovery elastic member 23 connecting the housing 1 and the coil 21, ensuring that the entire coil device is structurally complete and that the components are well related.

[0050] Its working principle is as follows: When the reel 21 rotates around the first direction to overcome the elastic force of the recovery elastic element 23 and release the cable 22, or rotates around the second direction opposite to the first direction and recovers the cable 22 under the elastic force of the recovery elastic element 23, the reduction wheel 31, which is fixedly connected to the reel 21, rotates synchronously. The reduction wheel 31 drives the centrifugal structure 32 to move through the gap fit between the guide boss 341 and the guide groove 342 of the guide fitting assembly 34. At this time, the centrifugal structure 32 generates centrifugal force and performs centrifugal motion under the drive of the rotation of the reduction wheel 31. At the same time, the centrifugal elastic element 33 continuously applies force to the centrifugal structure 32, driving the centrifugal structure 32 to perform centripetal motion. The centrifugal structure 32 works in concert with the centrifugal elastic element 33 to achieve force balance. When the centrifugal structure 32 performs centrifugal motion, it abuts against the reduction housing 30 to generate a driving force. The friction force that slows down the coil 21 is as follows: the faster the speed of the reduction wheel 31, the greater the centrifugal force on the centrifugal structure 32, the greater the force against the centrifugal elastic element 33, the greater the centrifugal displacement, the greater the force applied to the reduction housing 30, and the greater the friction force on the coil 21. When the speed of the reduction wheel 31 is slower, the centrifugal force on the centrifugal structure 32 is smaller, and it moves centripetally under the drive of the centrifugal elastic element 33. At the same time, it resets with the cooperation of the centrifugal elastic element 33. The smaller the force applied to the reduction housing 30, the smaller the friction force on the coil 21. The guide assembly 34 synchronously guides the centrifugal structure 32 to move smoothly in the preset direction, avoiding deviation and jamming, and ensuring that the centrifugal elastic element 33 drives the centrifugal structure 32 to move centripetally accurately and smoothly.

[0051] By adopting the above technical solution, not only are the effects of the original deceleration component 3, which can adaptively adjust the deceleration friction according to the rotation speed of the reel 21 to achieve smooth and controllable winding and unwinding, and the guiding and cooperating component 34, which ensures the smooth movement of the centrifugal structure 32, retained, but also by adding a centripetal elastic element 33, the centrifugal structure 32 can be effectively driven to make centrifugal movement. The centrifugal structure 32 can be accurately reset in conjunction with the centrifugal elastic element 33, avoiding problems such as deceleration effect deviation and component jamming caused by the centrifugal structure 32 not being able to reset in time due to residual centrifugal force. At the same time, the force on the centrifugal structure 32 can be further balanced to ensure the movement stability of the centrifugal structure 32 at different speeds, reduce the wear between the centrifugal structure 32 and the deceleration housing 30 and the guiding and cooperating component 34, extend the service life of the deceleration component 3 and the entire reel device, improve the reliability and stability of the device, and ensure that the winding and unwinding process of the cable 22 is always smooth and controllable, effectively avoiding the cable 22 swinging, knotting, wear and other situations, and better adapting to the usage requirements of equipment such as film and television lights.

[0052] In one embodiment, there are multiple centrifugal structures 32, and a centripetal elastic member 33 is connected between two adjacent centrifugal structures 32. The centripetal elastic member 33 is used to limit the direction of movement and position of the centrifugal structure 32, so that the centrifugal structure 32 moves centripetally.

[0053] In the deceleration assembly 3 of the coil device, the number of centrifugal structures 32 is set to multiple. Specifically, the deceleration assembly 3 includes a deceleration housing 30 fixedly connected to the housing 1, a deceleration wheel 31 disposed inside the deceleration housing 30, multiple centrifugal structures 32 movably connected to the deceleration wheel 31, centripetal elastic elements 33 connected to the centrifugal structures 32, and centripetal elastic elements 33 connected between adjacent centrifugal structures 32. The deceleration assembly 3 also includes a guide fitting assembly 34 connecting the deceleration wheel 31 and each centrifugal structure 32. The guide fitting assembly 34 includes a guide boss 341 and a guide groove 342 that is clearance-fitted with the guide boss 341. The guide boss 341 is disposed on one of the deceleration wheel 31 and the centrifugal structure 32, and the guide groove 342 is formed between the deceleration wheel 31 and the centrifugal structure 32. Another component, the centripetal elastic element 33, is connected between two adjacent centrifugal structures 32. The centripetal elastic element 33 is used to limit the direction and position of movement of the centrifugal structure 32, so that the centrifugal structure 32 moves centripetally. Its core function is to drive each centrifugal structure 32 to move centripetally. The reduction wheel 31 is fixedly connected to the coil 21 and can rotate synchronously. Each centrifugal structure 32 is movably matched with the reduction wheel 31 and connected to the centripetal elastic element 33. Multiple centrifugal structures 32 are evenly distributed around the circumference of the reduction wheel 31. All components work together to form a complete reduction assembly 3. The coil assembly 2 still includes a coil 21 that can rotate around the rotation axis X defined by the housing 1, a cable 22 wound on the coil 21, and a recovery elastic element 23 connecting the housing 1 and the coil 21, ensuring that the entire coil device is structurally complete and that the components are well correlated.

[0054] Its working principle is as follows: When the reel 21 rotates around the first direction to overcome the elastic force of the recovery elastic element 23 and release the cable 22, or rotates around the second direction opposite to the first direction to recover the cable 22 under the elastic force of the recovery elastic element 23, the reduction wheel 31, which is fixedly connected to the reel 21, rotates synchronously. The reduction wheel 31 drives multiple centrifugal structures 32 to move synchronously through the gap fit between the guide boss 341 and the guide groove 342 of the guide fitting assembly 34. At this time, each centrifugal structure 32 generates centrifugal force and performs centrifugal motion under the drive of the rotation of the reduction wheel 31. The centripetal elastic element 33 between two adjacent centrifugal structures 32 is stretched and continuously applies tension to each centrifugal structure 32, thereby driving each centrifugal structure 32 to perform centrifugal motion. The centrifugal elastic element 33 works together to achieve force balance of each centrifugal structure 32. When each centrifugal structure 32 performs centrifugal motion, it abuts against the reduction housing 30 and generates centrifugal force together. The frictional force that drives the reel 21 to decelerate, and the faster the speed of the deceleration wheel 31, the greater the centrifugal force on each centrifugal structure 32, the greater the force against the centrifugal elastic element 33, the greater the centrifugal displacement, and the greater the total force exerted by multiple centrifugal structures 32 on the deceleration housing 30, the greater the frictional force on the reel 21; when the speed of the deceleration wheel 31 is slower, the centrifugal force on each centrifugal structure 32 is smaller, and under the pulling force of the centrifugal elastic element 33 between adjacent centrifugal structures 32, they move centripetally, and simultaneously reset with the cooperation of the centrifugal elastic element 33. The smaller the total force exerted by multiple centrifugal structures 32 on the deceleration housing 30, the smaller the frictional force on the reel 21, and the guide assembly 34 synchronously guides each centrifugal structure 32 to move smoothly in a preset direction, avoiding deviation and jamming, and ensuring that the action of the centrifugal elastic element 33 driving each centrifugal structure 32 to move centrifugally is precise and synchronous.

[0055] By adopting the above technical solution, not only are the effects of the original deceleration component 3 (which can adaptively adjust the deceleration friction according to the rotation speed of the reel 21 to achieve smooth and controllable winding and unwinding) and the guiding component 34 (which ensures the smooth movement of the centrifugal structure 32) retained, but also by setting multiple centrifugal structures 32 and connecting centrifugal elastic elements 33 between adjacent centrifugal structures 32, multiple centrifugal structures 32 can perform centrifugal and centripetal movements synchronously. The centrifugal elastic elements 33 can apply a uniform centrifugal driving force to each centrifugal structure 32, ensuring that each centrifugal structure 32 is subjected to balanced force and moves synchronously, avoiding problems such as uneven deceleration force and device shaking caused by the movement deviation of a single centrifugal structure 32. At the same time, multiple centrifugal structures 32 The contact with the deceleration housing 30 increases the adjustment range of the deceleration friction force, improves the stability and reliability of the deceleration effect, and the centrifugal elastic element 33 works together to achieve precise reset of each centrifugal structure 32. This avoids problems such as component jamming and deceleration effect attenuation caused by the centrifugal structure 32 not being able to reset in time due to residual centrifugal force. It also reduces wear between the centrifugal structure 32 and the deceleration housing 30 and the guide assembly 34, extends the service life of the deceleration assembly 3 and the entire reel device, improves the stability and durability of the device, and ensures that the cable 22 is always stable and controllable during the winding and unwinding process. This effectively avoids cable 22 swinging, knotting, wear and other situations, and better adapts to the usage requirements of equipment such as film and television lights.

[0056] The newly added technical solution of the deceleration assembly 3 of the reel device is as follows: the number of centrifugal structures 32 is set to three. Specifically, the structure consists of three centrifugal structures 32 movably connected to the deceleration wheel 31 in the deceleration assembly 3. These three centrifugal structures 32 are evenly spaced along the circumference of the deceleration wheel 31 to ensure balanced force and synchronous movement. A centripetal elastic element 33 connects to each adjacent centrifugal structure 32. The three centrifugal elastic elements 33 and the three centrifugal structures 32 cooperate to form a closed-loop connection. The core function of the centrifugal elastic element 33 is to drive the three centrifugal structures 32 to move synchronously towards the center. Each centrifugal structure 32 is correspondingly connected to a centrifugal elastic element 33, and each centrifugal structure 32 is connected to the deceleration wheel 31. Each speed wheel 31 is provided with a guide fitting assembly 34. The guide fitting assembly 34 includes a guide boss 341 and a guide groove 342 that is clearance-fitted with the guide boss 341. The guide boss 341 is located on one of the speed reduction wheel 31 and the centrifugal structure 32, and the guide groove 342 is located on the other of the speed reduction wheel 31 and the centrifugal structure 32. The speed reduction wheel 31 is still fixedly connected to the coil 21 and can rotate synchronously. The three centrifugal structures 32, the three centrifugal elastic elements 33, the guide fitting assembly 34, the speed reduction housing 30, and the speed reduction wheel 31 together constitute the complete speed reduction assembly 3. The coil assembly 2 retains its original structure to ensure that the entire coil device is structurally complete and that all components are adapted and coordinated.

[0057] Its working principle is as follows: When the reel 21 rotates around the first direction to release the cable 22 or rotates around the second direction to retrieve the cable 22, the reduction wheel 31 rotates synchronously with the reel 21. Through the guide and engagement components 34, it drives the three centrifugal structures 32 to move synchronously. Under the action of centrifugal force, the three centrifugal structures 32 move centrifugally synchronously. At this time, the centripetal elastic element 33 between two adjacent centrifugal structures 32 is stretched. The centripetal elastic element 33 applies a uniform centripetal tension to each centrifugal structure 32, driving the three centrifugal structures 32 to move centripetally synchronously. The centripetal elastic element 33 corresponding to each centrifugal structure 32 works in concert to achieve the force balance of the three centrifugal structures 32. The three centrifugal structures 32 abut against the reduction housing 30 synchronously, and together generate the frictional force that drives the reel 21 to decelerate. Furthermore, the faster the speed of the reduction wheel 31, the greater the centrifugal force on the three centrifugal structures 32, the greater the force against the centrifugal elastic elements 33, the more consistent the centrifugal displacement, the greater the total force exerted by the three centrifugal structures 32 on the reduction housing 30, and the greater the frictional force on the coil 21. When the speed of the reduction wheel 31 is slower, the centrifugal force on the three centrifugal structures 32 is smaller, and they move centripetally under the synchronous pulling force of the three centrifugal elastic elements 33. At the same time, they reset synchronously with the cooperation of the corresponding centrifugal elastic elements 33. The smaller the total force exerted on the reduction housing 30, the smaller the frictional force on the coil 21. The guide assembly 34 ensures that the movement direction of the three centrifugal structures 32 is accurate, avoiding deviation, jamming, or asynchronous movement.

[0058] By adopting the aforementioned new technical solution, namely, specifying that there are three centrifugal structures 32 and corresponding centripetal elastic elements 33 and guide assembly 34, the three centrifugal structures 32 can achieve synchronous and balanced centrifugal and centripetal motion. The centripetal elastic elements 33 can apply uniform and synchronous centripetal driving force to the three centrifugal structures 32, effectively avoiding problems such as uneven deceleration force and device shaking caused by the movement deviation of a single centrifugal structure 32. The contact and cooperation between the three centrifugal structures 32 and the deceleration housing 30 can reasonably expand the adjustment range of deceleration friction force, improve the stability and reliability of deceleration effect, and at the same time, the uniform distribution of the three centrifugal structures 32 can make the deceleration force more balanced, reduce wear during device operation, extend the service life of the deceleration assembly 3 and the entire reel device, further improve the stability and durability of device operation, ensure that the cable 22 winding and unwinding process is smooth and controllable, and better adapt to the usage requirements of equipment such as film and television lights.

[0059] In other embodiments, the deceleration assembly 3 further includes a deceleration shaft connecting the deceleration wheel 31 and the centrifugal structure 32, and a centripetal elastic member 33 connected to the centrifugal structure 32. The deceleration shaft is located in the circumferential direction of the deceleration wheel 31, and the centrifugal structure 32 is connected to the deceleration shaft. The centrifugal structure 32 rotates around the deceleration shaft under the drive of the deceleration wheel 31 to perform centrifugal motion. The centrifugal elastic member 33 is used to limit the direction and position of the centrifugal structure 32 so that the centrifugal structure 32 performs centripetal motion.

[0060] The newly added technical solution of the deceleration assembly 3 of the coil device is as follows: the deceleration assembly 3 is newly provided with a deceleration shaft connecting the deceleration wheel 31 and the centrifugal structure 32, and a centripetal elastic element 33 connected to the centrifugal structure 32. The deceleration shaft is fixedly disposed on the circumference of the deceleration wheel 31 and is arranged at intervals along the circumference of the deceleration wheel 31. The centrifugal structure 32 is assembled with the deceleration shaft in a rotatable connection manner to ensure that the centrifugal structure 32 can rotate flexibly around the deceleration shaft. One end of the centrifugal elastic element 33 is connected to the centrifugal structure 32, and the other end is fixedly connected to the deceleration wheel 31 or the deceleration housing 30. The centrifugal elastic element 33 is used to restrict the centrifugal structure 32. The direction and position of the movement cause the centrifugal structure 32 to move centripetally. Its core function is to drive the centrifugal structure 32 to move centripetally. The newly added deceleration shaft and centripetal elastic element 33 work together with the original structure of the deceleration assembly 3 (deceleration housing 30, deceleration wheel 31, centrifugal structure 32, guide fitting assembly 34, etc.). The deceleration wheel 31 is still fixedly connected to the coil 21 and can rotate synchronously. The centrifugal structure 32 is still connected to the original centripetal elastic element 33 and adapted to the guide fitting assembly 34, together forming a complete deceleration assembly 3. The coil assembly 2 maintains its original structure unchanged, ensuring that the entire coil device structure is adapted and smoothly connected.

[0061] Its working principle is as follows: When the reel 21 rotates around the first direction to release the cable 22 or around the second direction to retrieve the cable 22, the reduction wheel 31 rotates synchronously with the reel 21. Since the centrifugal structure 32 is connected to the reduction shaft located around the reduction wheel 31, under the drive of the reduction wheel 31, the centrifugal structure 32 rotates around the reduction shaft and thus performs centrifugal motion. At this time, the centripetal elastic element 33 is stretched or compressed and generates elastic force, continuously applying centripetal driving force to the centrifugal structure 32, driving the centrifugal structure 32 to perform centripetal motion, and working together with the original centripetal elastic element 33 to achieve force balance of the centrifugal structure 32; during the centrifugal motion, the centrifugal structure 32 abuts against the reduction housing 30, generating frictional force that drives the reel 21 to decelerate, and the rotational speed of the reduction wheel 31... The faster the rotation speed, the greater the amplitude of the centrifugal structure 32's rotation around the reduction shaft, the more obvious the centrifugal displacement, the greater the force against the centrifugal elastic element 33, the greater the force applied to the reduction housing 30, and the greater the frictional force on the coil 21. When the rotation speed of the reduction wheel 31 is slower, the centrifugal force on the centrifugal structure 32 is smaller. Driven by the centrifugal elastic element 33, it rotates in the opposite direction around the reduction shaft in a centrifugal motion. At the same time, it resets with the cooperation of the centrifugal elastic element 33. The smaller the force applied to the reduction housing 30, the smaller the frictional force on the coil 21. The guide assembly 34 simultaneously guides and limits the movement of the centrifugal structure 32, ensuring that the trajectory of the centrifugal structure 32's rotation around the reduction shaft is accurate and avoiding deviation or jamming.

[0062] By adopting the aforementioned new technical solution, namely the addition of a reduction shaft and a centrifugal elastic element 33, with the reduction shaft located circumferentially on the reduction wheel 31 and the centrifugal structure 32 connected to and able to rotate around the reduction shaft, the movement trajectory of the centrifugal structure 32 is effectively limited, making the centrifugal movement of the centrifugal structure 32 more precise and stable. This avoids problems such as shaking and deviation during the movement of the centrifugal structure 32. At the same time, the centrifugal elastic element 33 can stably drive the centrifugal structure 32 to make centrifugal movement. Working together with the centrifugal elastic element 33, the centrifugal structure 32 can achieve precise reset, avoiding problems such as attenuation of deceleration effect and component jamming caused by the centrifugal structure 32 not being able to reset in time due to residual centrifugal force. This further improves the stability and reliability of the deceleration assembly 3, expands the adjustment range of deceleration friction, reduces wear between the centrifugal structure 32 and each mating component, extends the service life of the deceleration assembly 3 and the entire reel device, ensures that the cable 22 winding and unwinding process is smooth and controllable, and better adapts to the usage requirements of equipment such as film and television lights.

[0063] like Figure 8 As shown, in one embodiment, the coil device further includes a lever assembly 4 disposed on the housing 1, the lever assembly 4 being used to limit the rotation of the coil assembly 2.

[0064] The specific addition to the new technical solution of the coil device is as follows: a lever assembly 4 is added to the coil device. The lever assembly 4 is installed on the housing 1 and has a rotatable or slidable fit with the housing 1. One end of the lever assembly 4 extends into the interior of the housing 1 and corresponds to the coil assembly 2, while the other end protrudes outside the housing 1 for easy operation. Its core function is to guide the unidirectional rotation of the coil assembly 2, that is, the rotation direction of the coil assembly 2 is limited by different positions of the lever assembly 4. The newly added lever assembly 4 is compatible with the original structure of the coil device (housing 1, coil assembly 2, reduction assembly 3, etc.). The coil assembly 2 still includes a coil 21 that can rotate around the rotation axis X defined by the housing 1, a cable 22 wound on the coil 21, and a retraction elastic element 23 connecting the housing 1 and the coil 21. The reduction assembly 3 retains its original structure and remains connected to the coil assembly 2, ensuring the integrity of the entire coil device structure and the smooth connection and coordination of all components.

[0065] Its working principle is as follows: When the operator needs to release cable 22, the lever assembly 4 is moved to the first position. At this time, the lever assembly 4 does not restrict the rotation of the cable reel assembly 2 in the first direction. The cable reel assembly 2 can rotate normally in the first direction, thereby overcoming the elastic force of the retraction elastic element 23 to release cable 22. The deceleration component 3 simultaneously plays an adaptive deceleration role, ensuring that the cable 22 release process is smooth and controllable. When the operator moves the lever assembly 4 to the second position, the lever assembly 4 limits the rotation of the cable reel assembly 2 in the second direction, preventing the cable reel assembly 2 from rotating in the second direction. At this time, the cable reel assembly 2 cannot retract cable 22 under the elastic force of the retraction elastic element 23, thereby achieving one-way locking after cable 22 is released, ensuring that cable 22 maintains its current release length. When it is necessary to release the rotation restriction of the cable reel assembly 2 in the second direction and retract cable 22, the lever assembly 4 is moved back to the first position. The lever assembly 4 has a simple structure and is easy to operate, and can quickly guide and switch the one-way rotation of the cable reel assembly 2.

[0066] By adopting the aforementioned new technical solution, namely, adding a lever assembly 4 installed on the housing 1 to guide the spool assembly 2 to rotate in one direction, the lever assembly 4, when moved to the first position, allows the spool assembly 2 to rotate in the first direction to release the cable 22, and when moved to the second position, restricts the spool assembly 2 to rotate in the second direction. This achieves one-way locking after the cable 22 is released, effectively preventing the cable 22 from retracting itself due to the elastic force of the retractable elastic element 23 during use, ensuring the stability of the cable 22 length, and significantly improving the convenience and reliability of the spool device. At the same time, the lever assembly 4 has a simple structure, is easy to assemble, and is well compatible with the original structure of the device. It does not require major modifications to the original components such as the housing 1 and the spool assembly 2, effectively reducing manufacturing costs. Moreover, its operation method is simple and easy to understand, and operators can quickly master the operation method.

[0067] In one embodiment, a ratchet 24 is coaxially provided on the coil 21, and a plurality of one-way stop grooves 241 are sequentially provided on the circumference of the ratchet 24; the lever assembly 4 includes a lever shaft 41 provided on the housing 1, a stop link 42 connected to the lever shaft 41, a stop elastic member 43 connected to the stop link 42, and a lever 44 connected to the lever shaft 41; the stop link 42 rotates around the lever shaft 41 under the elastic force of the stop elastic member 43 to engage in the one-way stop groove 241; the lever 44 can drive the stop link 42 to rotate around the lever shaft 41 to disengage from the one-way stop groove 241.

[0068] The newly added technical solution of the spool device is as follows: its structure consists of a ratchet 24 coaxially fixed on the spool 21 of the spool device. Multiple one-way stop grooves 241 are sequentially spaced along the circumferential sidewall of the ratchet 24, and the structure of each one-way stop groove 241 is adapted to the end of the stop link 42. The newly added lever assembly 4 specifically includes a lever shaft 41, a stop link 42, a stop elastic element 43, and a lever 44. The lever shaft 41 is fixedly installed on the housing 1. The stop link 42 is rotatably connected to the lever shaft 41, allowing it to rotate flexibly around the lever shaft 41. One end of the stop elastic element 43 is connected to the stop link 42, and the other end is fixedly connected to the housing 1 or the lever shaft 41, used to apply force to the stop link 42. With the addition of elastic force, the lever 44 is fixedly connected to the lever shaft 41, with one end exposed outside the housing 1 for easy operation, and the other end linked with the stop link 42. The lever assembly 4 is compatible with the original structure of the coil device (housing 1, coil assembly 2, deceleration assembly 3, etc.). The coil assembly 2 still includes a coil 21 that can rotate around the rotation axis X defined by the housing 1, a cable 22 wound on the coil 21, and a retraction elastic element 23 connecting the housing 1 and the coil 21. The deceleration assembly 3 maintains its original structure and remains connected to the coil assembly 2. The ratchet 24 rotates coaxially and synchronously with the coil 21. The end of the stop link 42 corresponds to the one-way stop groove 241 around the ratchet 24, ensuring that the entire coil device structure is intact, the components are smoothly connected, and the coordination is harmonious.

[0069] Its working principle is as follows: Under normal conditions, the stop link 42 rotates around the lever shaft 41 under the elastic force of the stop elastic element 43, and its end is engaged in the one-way stop groove 241 of the ratchet 24. At this time, the cable reel assembly 2 is restricted to rotating in the second direction under the cooperation of the ratchet 24 and the stop link 42, and can only rotate in the first direction to release the cable 22. When the operator needs to release the cable 22, the cable reel 21 rotates in the first direction, and the ratchet 24, which is coaxial with the cable reel 21, rotates synchronously in the first direction. At this time, the one-way stop groove 241 of the ratchet 24 squeezes the end of the stop link 42, forcing the stop link 42 to overcome the elastic force of the stop elastic element 43 and rotate in the opposite direction around the lever shaft 41. Its end exits the currently corresponding one-way stop groove 241. As the ratchet 24 continues to rotate, the stop link 42 is engaged in the subsequent one-way stop grooves under the elastic force of the stop elastic element 43. The one-way stop groove 241 allows the coil 21 to rotate smoothly in the first direction, while the deceleration component 3 simultaneously performs adaptive deceleration to ensure a smooth and controllable release process for the cable 22. When it is necessary to allow the coil 21 to rotate in the second direction to retract the cable 22, the operator manipulates the lever 44 exposed in the housing 1. The lever 44 drives the lever shaft 41 to rotate, which in turn drives the stop link 42 to rotate around the lever shaft 41. This causes the stop link 42 to overcome the elastic force of the stop elastic element 43 and exit the one-way stop groove 241, releasing the stop restriction on the ratchet 24. At this time, the coil 21 can rotate in the second direction, and the cable 22 is retracted under the elastic force of the retraction elastic element 23. After the retraction is completed, the lever 44 is released, and the stop link 42 is re-engaged in the one-way stop groove 241 under the elastic force of the stop elastic element 43, thus restricting the coil 21 to rotate in the second direction again.

[0070] By adopting the aforementioned new technical solution, namely, a ratchet 24 with a one-way stop groove 241 is coaxially arranged on the reel 21, and a lever assembly 4 is provided, consisting of a lever shaft 41, a stop link 42, a stop elastic element 43, and a lever 44. Under the elastic force of the stop elastic element 43, the stop link 42 is engaged in the one-way stop groove 241, and the lever 44 can drive the stop link 42 to exit the one-way stop groove 241. This can accurately achieve one-way rotation guidance of the reel assembly 2, ensuring that the reel 21 can only rotate in the first direction to release the cable 22, effectively preventing the cable 22 from retracting itself due to the elastic force of the retraction elastic element 23 during use, and ensuring the length of the cable 22. Stable; at the same time, the ratchet 24 and the stop link 42 have a stable cooperation structure. The setting of multiple one-way stop grooves 241 can realize the positioning of different release lengths of the cable reel 21. The setting of the stop elastic element 43 ensures the reliable engagement of the stop link 42 and the one-way stop groove 241. The lever 44 is easy to operate and can quickly release the stop restriction for cable 22 retrieval. The entire lever assembly 4 has a compact structure, is easy to assemble, and has good compatibility with the original structure of the device. There is no need to make major modifications to the original parts, reducing the production and manufacturing costs, significantly improving the reliability and convenience of the cable reel device, and better adapting to the actual needs of on-site wiring and fixed-point use of equipment such as film and television lights.

[0071] like Figure 9 and Figure 10 As shown, in one embodiment, the stop linkage 42 includes a stop connecting portion 421, a stop portion 422 connected to the stop connecting portion 421, and an elastic connecting portion 423 connected to the stop connecting portion 421. The stop connecting portion 421 is connected to the lever shaft 41 and can rotate around the lever shaft 41. The stop connecting portion 421 is provided with a linkage groove 4211. The stop portion 422 is located in the circumferential direction of the stop connecting portion 421 and is used to engage or disengage from the one-way stop groove 241. The elastic connecting portion 423 is located in the circumferential direction of the stop connecting portion 421 and is connected to the stop elastic member 43. The lever 44 includes a lever connecting portion 441. The lever body 442 is connected to the lever connection part 441. The lever body 442 is connected to the lever shaft 41 and can rotate around the lever shaft 41. The lever body 442 is provided with a linkage block 4421 for inserting into the linkage groove 4211. The housing 1 is provided with a lever slide groove 11. The lever slide groove 11 is provided with a first groove wall 111 and a second groove wall 112. When the lever body 442 is moved toward the first groove wall 111, the linkage block 4421 is inserted into the linkage groove 4211, and the lever 44 is linked with the stop link 42. When the lever body 442 is moved toward the second groove wall 112, the linkage between the lever 44 and the stop link 42 is released.

[0072] like Figure 11 and Figure 12As shown, the newly added technical solution of the lever assembly 4 of the coil device is as follows: the stop link 42 in the lever assembly 4 specifically includes a stop connecting part 421, a stop part 422, and an elastic connecting part 423, which are integrally formed or fixedly connected. The stop connecting part 421 is rotatably connected to the lever shaft 41 and can rotate flexibly around the lever shaft 41. The stop connecting part 421 is provided with a linkage groove 4211 for linkage with the lever 44. The stop part 422 is integrally connected to the circumferential side wall of the stop connecting part 421, and its end structure is circumferentially connected to the ratchet 24 for one-way stop. The movable groove 241 is adapted to engage or disengage from the one-way stop groove 241 to stop and release the rotation of the coil 21; the elastic connecting part 423 is also integrally connected to the circumferential side wall of the stop connecting part 421, and is arranged at intervals from the stop part 422. The elastic connecting part 423 is provided with a connecting structure for connecting to one end of the stop elastic member 43, and the other end of the stop elastic member 43 is fixedly connected to the housing 1 or the lever shaft 41; the lever 44 specifically includes a lever connecting part 441 and a lever body 442, which are integrally formed or fixedly connected structures, and the lever body 442 is fixedly connected to the lever shaft 41. The lever assembly 442 is rotatable around the lever shaft 41. A linkage block 4421 is provided on the side of the lever body 442 facing the stop link 42. The structure of the linkage block 4421 is adapted to the linkage groove 4211 on the stop connection part 421, and is used to insert into the linkage groove 4211 to achieve linkage between the lever 442 and the stop link 42. A lever slide groove 11 is provided on the housing 1 at a position corresponding to the lever body 442. The lever slide groove 11 is elongated and has a first groove wall 111 and a second groove wall 112 arranged opposite to each other. The lever body 442 can move along the lever slide groove 11 between the first groove wall 111 and the second groove wall 112. Each component is coaxially mounted on the spool 21 with the ratchet 24 and the original structure of the spool device (housing 1, spool assembly 2, deceleration assembly 3, etc.). The spool assembly 2 still includes the spool 21 that can rotate around the rotation axis X defined by the housing 1, the cable 22 wound on the spool 21, and the retraction elastic element 23 that connects the housing 1 and the spool 21. The deceleration assembly 3 maintains its original structure and remains connected to the spool assembly 2. The ratchet 24 rotates synchronously with the spool 21 on the same axis. The stop part 422 corresponds to the one-way stop groove 241, ensuring that the entire spool device structure is complete, the components are smoothly connected, and they are coordinated.

[0073] Its working principle is as follows: Under normal conditions, the operator moves the lever body 442 to one side of the second groove wall 112 of the lever slide groove 11. At this time, the linkage block 4421 exits from the linkage groove 4211, and the lever 44 is disengaged from the stop linkage 42. The stop connection part 421 of the stop linkage 42 rotates around the lever shaft 41. Under the elastic force of the stop elastic element 43 (the stop elastic element 43 is connected to the elastic connection part 423 and applies elastic force), the stop part 422 is engaged in the one-way stop groove 241 of the ratchet 24, restricting the cable reel 21 from rotating in the second direction. When it is necessary to release the cable 22, the cable reel 21 rotates in the first direction, and the ratchet 24, which is coaxial with the cable reel 21, rotates synchronously. Rotating in the first direction, the one-way stop groove 241 of the ratchet 24 presses against the stop part 422, forcing the stop link 42 to overcome the elastic force of the stop elastic element 43 and rotate around the lever shaft 41. The stop part 422 exits the current one-way stop groove 241. As the ratchet 24 continues to rotate, the stop part 422 enters the next one-way stop groove 241 in sequence under the elastic force of the stop elastic element 43. During this process, since the lever 44 and the stop link 42 have been disengaged, the rotation of the stop link 42 will not drive the lever body 442 to rotate. The lever body 442 remains stationary, preventing the lever 44 from shaking synchronously with the stop link 42, thus improving the user's operating experience. The deceleration assembly 3 synchronously performs adaptive deceleration to ensure the smooth release of cable 22. When it is necessary to release the rotation restriction of the cable reel 21 in the second direction to retrieve cable 22, the operator manipulates the lever body 442 and moves it toward the first groove wall 111 of the lever slide groove 11. At this time, the lever body 442 rotates around the lever shaft 41, causing the linkage block 4421 on it to insert into the linkage groove 4211 of the stop connection part 421, realizing the linkage between the lever 44 and the stop link 42. Continuing to move the lever body 442, the lever 44, through the cooperation of the linkage block 4421 and the linkage groove 4211, drives the stop link 42 to rotate around the lever shaft 41, causing the stop part 42 to rotate. 22 overcomes the elastic force of the stop elastic element 43 and exits the one-way stop groove 241, releasing the stop restriction on the ratchet 24. At this time, the coil 21 can rotate in the second direction and the cable 22 is retrieved under the action of the elastic force of the recovery elastic element 23. After retrieval, the operator moves the lever body 442 toward the second groove wall 112 of the lever slide groove 11. The linkage block 4421 exits from the linkage groove 4211, and the linkage between the lever 44 and the stop link 42 is released again. The stop link 42 is reset under the action of the elastic force of the stop elastic element 43, and the stop part 422 is re-engaged into the one-way stop groove 241, which restricts the coil 21 from rotating in the second direction again. The lever body 442 remains stationary.

[0074] By adopting the aforementioned new technical solution, namely clarifying the specific structure of the stop link 42 and the lever 44, adding the lever slide groove 11 and limiting the linkage state and corresponding function of the lever 44 at different moving positions, the structure of the lever assembly 4 is made clearer and the cooperation more precise. The stop connection part 421, the stop part 422, and the elastic connection part 423 of the stop link 42 have clear division of labor, ensuring the stable realization of the stop and elastic reset functions. The linkage block 4421 of the lever 44 cooperates with the linkage groove 4211 of the stop connection part 421. Combined with the limiting effect of the lever slide groove 11, the linkage and release of the lever 44 and the stop link 42 can be accurately realized. When the lever body 442 moves toward the first groove wall 111, it can reliably drive the stop link 42 to retract. The one-way stop groove 241 ensures smooth cable retrieval. When the lever body 442 moves towards the second groove wall 112, the linkage can be stably released, keeping the lever body 442 stationary while the cable reel 21 rotates in the first direction. This prevents the lever 44 from shaking and affecting operation, significantly improving the user experience. At the same time, this structural design makes the assembly of the lever assembly 4 more compact and the cooperation of each component more reliable. It further improves the stability and reliability of the one-way rotation guidance of the cable reel device and the positioning and locking of the cable 22, ensuring that the length of the cable 22 is stable after release and the retrieval operation is convenient. It does not require major modifications to the original components, has good adaptability, reduces production and manufacturing costs, and better meets the actual needs of on-site wiring and fixed-point use of equipment such as film and television lights.

[0075] In one embodiment, the lever 44 further includes a lever elastic element 443 connected to the lever body 442, the lever elastic element 443 being used to drive the lever body 442 toward the second groove wall 112.

[0076] The core of the new technical solution for the lever assembly 4 of the coil device is the addition of a lever elastic element 443: the lever assembly 4 adds a lever elastic element 443 that is fixedly connected to the lever body 442. One end of the lever elastic element 443 is connected to the lever body 442, and the other end is fixed to the housing 1 or the lever shaft 41. Its core function is to drive the lever body 442 to move towards the second groove wall 112 of the lever slide groove 11 and hold it in that position. It works in coordination with the lever body 442, the linkage block 4421, the original stop elastic element 43, the ratchet 24, and other structures without changing the overall structural framework of the original coil device. Only the elastic element is added to the lever 44 structure to ensure compatibility with the original lever connection part 441, linkage groove 4211, and other structures.

[0077] Its working principle is as follows: Under normal conditions, the elastic element 443 continuously applies an elastic force to the lever body 442, driving the lever body 442 to move towards the second groove wall 112 of the lever slide groove 11 and maintain it stably in that position. At this time, the lever 44 is disengaged from the stop link 42. Under the action of the stop elastic element 43, the stop link 42 causes the stop part 422 to engage with the one-way stop groove 241 of the ratchet 24. The cable reel 21 can rotate normally in the first direction to release the cable 22. The stop part 422 engages with the subsequent one-way stop groove 241 as the ratchet 24 rotates. The lever body 442 remains stationary and does not shake with the rotation of the stop link 42. When it is necessary to release the stop to retrieve the cable 22, the operator needs to... The elastic force of the lever elastic element 443 moves the lever body 442 toward the first groove wall 111, causing the linkage block 4421 to insert into the linkage groove 4211 of the stop connection part 421, realizing the linkage between the lever 44 and the stop link 42, thereby driving the stop part 422 to exit the one-way stop groove 241, releasing the rotation restriction of the coil 21; when the lever body 442 is released, the elastic force of the lever elastic element 443 will immediately drive the lever body 442 to automatically reset toward the second groove wall 112, the linkage block 4421 will exit the linkage groove 4211, restoring the non-linkage state of the lever 44 and the stop link 42, and the stop part 422 will re-engage into the one-way stop groove 241, ensuring that the rotation restriction of the coil 21 is restored.

[0078] By adopting the above technical solution, operators do not need to manually reset the lever body 442 to the position of the second groove wall 112. The lever elastic element 443 can automatically drive the lever body 442 to reset and remain stationary, effectively simplifying the operation process and avoiding accidental triggering of linkage due to untimely manual reset. At the same time, it ensures that the lever 44 and the stop linkage 42 are in a stable non-linkage state under normal conditions, preventing the lever 44 from shaking and affecting the operating experience, improving the automation level and ease of operation of the lever assembly 4, reducing operational errors, and further ensuring the stability of the unidirectional rotation guidance of the coil device and the positioning of the cable 22, adapting to the on-site use needs of equipment such as film and television lights.

[0079] Secondly, a film and television lighting device is provided, including a lamp body and the aforementioned cable reel device, wherein the lamp body is connected to the cable 22.

[0080] This film and television lighting equipment connects the light body to the cable 22 of the cable reel device. Combined with the stable winding and positioning functions of the cable reel device, it enables the orderly storage and length fixation of the film and television lighting cable 22, avoiding messy tangling of the cable 22, ensuring the convenience and stability of wiring when using the film and television lighting equipment on site, improving the practicality and ease of operation of the film and television lighting equipment, and adapting to the wiring needs of various film and television shooting scenarios.

[0081] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
