Description

Technical Field

[0001] This utility model relates to the field of lamp holder support arm technology, and in particular to an adjustable lamp holder support arm. Background Technology

[0002] Photography has required suitable light to capture images since its inception. Early photographers could only use natural light or simple fixed light sources. With the development of photographic technology, especially the rise of indoor photography and commercial photography, the demand for artificial light sources has increased. Light stand support arms have become an important tool for fixing and adjusting photographic lights, helping photographers to adjust them according to the shooting theme and creative ideas.

[0003] The lamp holder support arm consists of a base, support arm, connecting components, and a lamp mounting section. The base can be a tripod or wall-mounted type. The support arm is multi-section and telescopic, and is commonly made of materials such as aluminum alloy. The connecting components include a rotating joint and a locking device. The lamp mounting section has a universal interface at the top. Its working principle is based on the stability of a triangle. Through structural design and material properties, the support arm can bear the weight of the lamp and maintain overall stability.

[0004] Current support arms have significant limitations in lighting applications. In practice, when adjustments are needed based on different shooting requirements or lighting ranges, quick splicing between supports is not possible, making it difficult to flexibly change the overall length of the support arm. Furthermore, angle adjustment is cumbersome and inefficient, failing to allow for quick and precise adjustments based on actual lighting angle requirements. This greatly limits the optimization and diversified application of lighting effects, reducing work efficiency and user experience. Therefore, an adjustable light stand support arm is proposed to solve these problems. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 2 and Figure 5 This utility model provides an embodiment of an adjustable lamp holder support arm, including a bracket 1. The bracket 1 serves as the basic structure of the entire lamp holder support arm, providing an installation and support platform for subsequent components. The bracket 1 has an installation port 2 inside, which is used to accommodate a connecting rod 3 and provide it with sliding space, thereby enabling the bracket 1 to be spliced ​​to achieve length adjustment. The installation port 2 is provided with a docking mechanism for docking, which enables the bracket 1 to be connected and docked with other components or multiple brackets 1. The bracket 1 is externally fixedly connected with a fixing block 9, which is used to install and fix other related components and is an important intermediate structure for connecting photographic equipment and the bracket 1. The fixing block 9 is externally provided with an installation mechanism for installation, which enables convenient installation and removal of photographic equipment on the fixing block 9. The fixing block 9 is internally provided with an adjustment mechanism, which can adapt the size of the photographic equipment installed on the fixing block 9 and tighten it. The docking mechanism is externally provided with a fixing mechanism, which can ensure the connection of the bracket 1 after docking is stable.

[0035] The docking mechanism includes a connecting rod 3, which is externally slidably connected to the inside of the mounting port 2. The operator can slide the connecting rod 3 in the mounting port 2 according to actual needs, thereby adjusting the overall length of the bracket 1. The connecting rod 3 is externally fixedly connected to a mounting block 5, which is used to install lighting equipment to meet the lighting needs of different scenarios. The connecting rod 3 is externally fixedly connected to a rotating stud 6, which can be used to connect other brackets 1 to realize the combined use of multiple brackets 1. The connecting rod 3 is externally fixedly connected to a limiting block 4, which can limit the sliding range of the connecting rod 3 in the mounting port 2 to ensure the maximum installation length of the connecting rod 3. The bracket 1 has a fixing port 8 on its outside, which provides an installation position for the rotating stud 18 to fix the position of the connecting rod 3.

[0036] The fixed port 8 is internally threaded with a rotating stud 3 18. The bottom end of the rotating stud 3 18 contacts the outside of the connecting rod 3. By rotating the rotating stud 3 18, its bottom end can be pressed against the connecting rod 3, thereby fixing the position of the connecting rod 3. The fixing mechanism includes a rotating block 19. The inside of the rotating block 19 is fixedly connected to the outside of the rotating stud 3 18. The rotating block 19 can drive the rotating stud 3 18 to rotate, thereby fixing and loosening the connecting rod 3. The outside of the rotating block 19 is fixedly connected with a control block 20. The control block 20 allows the operator to manually rotate the rotating block 19, making the operation more convenient. The outside of the bracket 1 is fixedly connected with an anti-collision pad 7. The anti-collision pad 7 can prevent the bracket 1 from being damaged by collisions with other objects during use. The outside of the limiting block 4 contacts the outside of the bracket 1, which plays a role in limiting the sliding range of the connecting rod 3 and ensuring the stability of the bracket 1 adjustment.

[0037] Reference Figure 1 , Figure 2 and Figure 4 The installation mechanism includes a disassembly block 10, which is externally slidably connected to the outside of a fixed block 9. The disassembly block 10 and the fixed block 9 cooperate to enable quick installation and disassembly of photographic equipment. The fixed block 9 has a sliding groove 16 on its outside, which provides a track for the sliding of the disassembly block 10 to ensure its smooth sliding. A locking block 17 is fixedly connected inside the sliding groove 16. The locking block 17 can play a certain positioning and limiting role for the disassembly block 10. The top of the locking block 17 contacts the inside of the disassembly block 10. The locking block 17 is oblique in shape. This shape design facilitates the sliding of the disassembly block 10 in the sliding groove 16 and its engagement with the locking block 17 at a suitable position.

[0038] Reference Figures 1 to 3The adjustment mechanism includes a rotating stud 11, which is externally threaded into the interior of a fixed block 9. The rotating stud 11 can move within the fixed block 9 when rotated. A limiting block 13 is fixedly connected to the outside of the rotating stud 11, moving with it and providing both pushing and fixing for the photographic equipment. A spring 12 is fixedly connected to the end of the limiting block 13 furthest from the disassembly block 10, providing elastic support and allowing it to better fit the photographic equipment. A rotating cap 14 is fixedly connected to the end of the rotating stud 11 furthest from the disassembly block 10, facilitating operation. The operator manually rotates the rotating stud 2 11 to operate the adjustment mechanism. The external fixed connection of the limit block 2 13 is the limit block 3 15. The limit block 3 15 and the limit block 2 13 work together to fix the photographic equipment. The fixed block 9 has a slot inside. The external sliding connection of the limit block 3 15 is in the slot. The slot provides a sliding track for the limit block 3 15 to ensure its movement stability. The other end of the spring 12 is fixedly connected to the inside of the fixed block 9 to provide elastic restoring force for the entire adjustment mechanism. The external sliding connection of the limit block 3 15 is in the inside of the fixed block 9 to ensure that the limit block 3 15 moves stably within the fixed block 9.

[0039] Working principle: When the operator needs to install photographic equipment, by rotating the rotating cap 14, the rotating stud 11 drives the limiting block 13 to slide inside the fixing block 9 and the disassembly block 10, thereby adjusting the size of the cavity between the fixing block 9 and the disassembly block 10 to install photographic equipment of different sizes. After adjustment, the outside of the photographic equipment is slid into the cavity between the fixing block 9 and the disassembly block 10. At this time, by rotating the rotating cap 14 in the opposite direction, the rotating stud 11 will tightly push the limiting block 13 and the limiting block 15 to fit against the outside of the photographic equipment, thus completing the quick installation of the photographic equipment. Rotating the rotating cap 14 in the opposite direction again allows for quick disassembly of the photographic equipment. By quickly installing and disassembling photographic equipment of different sizes, the preparation time can be reduced, and the simple operation method ultimately improves work efficiency.

[0040] During photography, the overall length of bracket 1 can be adjusted as needed to install lighting equipment. The control connecting rod 3 can be adjusted to slide inside different mounting ports 2 to suit different usage requirements. After adjusting the connecting rod 3, the position of the connecting rod 3 can be restricted by rotating the control block 20, causing the rotating block 19 to drive the rotating stud 18 to achieve a fixed connection between the connecting rod 3 and bracket 1. At this time, the lighting equipment can be installed through the mounting block 5, and other brackets 1 can be connected by rotating the stud 16. When multiple brackets 1 are connected through the connecting rod 3, the angle can be adjusted first and then fixed by rotating the control block 20. This allows for quick angle adjustment according to different usage requirements, and the installation length of the connecting rod 3 can be adjusted as needed. The maximum installation length is at the position of the limit block 14. Through quick docking and angle adjustment between brackets 1, the practicality of the entire bracket 1 is improved. It is simple to operate, easy to learn, and improves the overall work efficiency.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
