Description

TECHNICAL FIELD

[0001] The utility model relates to a lamp base support reinforcing structure. BACKGROUND

[0002] Due to its own structural characteristics, the overall quality of the searchlight and large stage lamp is close to 200kg, and most of the weight is concentrated in the lamp head part. During actual fixing, installation and use, this special weight distribution mode makes the base become the force core and needs to stably bear great pressure or tension for a long time. Once the bearing capacity of the base is insufficient, the lamp is prone to imbalance and tilting, which not only affects normal lighting effect, but also may cause a chain reaction due to lamp toppling, causing direct physical damage to surrounding expensive stage equipment, scenery and on-site staff and bringing serious safety accident risks. The traditional stage lamp base is mostly made of sheet metal. Although the sheet metal process can realize relatively complex modeling design and has certain cost advantage, the essential material characteristics determine its mechanical performance short board. In the face of high-strength use demand of heavy searchlight and large stage lamp, the sheet metal part is difficult to provide reliable support stiffness. In the long-term use process of the lamp, the sheet metal base is prone to deformation, such as bending and concave, under the action of continuous heavy pressure or tension, thereby causing the lamp irradiation angle deviation and failing to accurately position the lighting area, greatly reducing the artistic expression and functionality of the stage light.

[0003] To overcome the strength dilemma of the traditional sheet metal base, some manufacturers try to replace it with higher strength metal materials. For example, aviation aluminum alloy or high-strength stainless steel is used to make the base main structure. These advanced metal materials have excellent mechanical properties and higher yield strength than ordinary sheet metal, which can still maintain the stability of the structure under the action of greater external force, effectively resist the heavy pressure and tension of the lamp, and ensure the stable state of the fixed lamp. In addition to material innovation, many improvements have been made in structural design. On the one hand, the contact area of the base is increased to disperse the pressure, and a wider and thicker base chassis is designed to evenly distribute the weight of the lamp to a larger range of support plane, reducing the pressure value per unit area; on the other hand, a complex reinforcing frame structure is introduced inside the base, similar to the honeycomb or truss type internal support system, which decomposes the external force from the lamp and evenly guides it through multiple force transmission paths, avoiding stress concentration and local deformation, and strengthening the bearing efficiency of the overall structure. Whether it is the use of high-end metal materials or the construction of complex internal support structure, it inevitably leads to a substantial increase in cost. The procurement cost of high-end metal materials is much higher than that of ordinary sheet metal, and its processing difficulty is higher, which requires more precise processing equipment and skilled operators, further increasing the manufacturing cost.

[0024] Embodiment, please refer to Figs. 1-2 As shown in the figure:

[0025] A lamp base support reinforcing structure, comprising top plate 100 and bottom plate 200 arranged at intervals;The top plate 100 and bottom plate 200 are connected with the shell 300;Top plate 100 as the component directly bearing the weight of lamp;The bottom plate 200 can increase the contact area with the support plane (such as ground, stage surface, etc.);The shell 300 is formed with accommodating space;The reinforcing assembly 400 is arranged in the accommodating space;Accommodating space provides reasonable installation area for reinforcing assembly 400;The reinforcing assembly 400 is connected with the bottom plate 200 and the top plate 100 respectively;Reinforcing assembly 400 connects the bottom plate 200 and the top plate 100, greatly enhances the mechanical correlation between the two;Compared with simply relying on shell 300 to transmit force, reinforcing assembly 400 can more directly and efficiently share the pressure / tension borne by top plate 100;In an embodiment, the reinforcing assembly 400 is preferably arranged in the middle of the accommodating space;

[0026] In an embodiment, the reinforcing assembly 400 comprises two first reinforcing plates 410 arranged oppositely; a power supply mounting groove 420 is formed between the two first reinforcing plates 410; and the space between the reinforcing assemblies 400 is fully utilized. On the one hand, the power supply 421 is mounted in a position close to the center of the base and protected, which is conducive to reducing the overall gravity center of the lamp and further improving the stability; on the other hand, it avoids the need to additionally design an external mounting structure for the power supply 421 alone, thereby simplifying the overall structure of the lamp; the two oppositely arranged first reinforcing plates 410 serve as the main longitudinal support structure and bear most of the pressure vertically transmitted from the top plate 100 and conduct it to the bottom plate 200. The first reinforcing plate 410 is connected to a plurality of second reinforcing plates 430 arranged at intervals on the side away from the other first reinforcing plate 410. The second reinforcing plates 430 are used to bear the force in the vertical direction on the one hand, and can also play a role in lateral reinforcement on the other hand. When the base is subjected to complex external forces in non-vertical directions, the second reinforcing plates 430 can disperse the force to avoid the failure of the first reinforcing plates 410 due to excessive lateral stress, and comprehensively improve the ability of the base to cope with complex stress working conditions; the first reinforcing plates 410 and the second reinforcing plates 430 work together to increase the connection area with the top and the bottom plate 200, thereby improving the stability and strength.

[0027] In an embodiment, the shell 300 is connected in the middle of the top plate 100 and the bottom plate 200; the shell 300 is composed of sheet metal bending; the corner of the bottom plate 200 and the top plate 100 extends outward to form an extension 10; the support column 20 is arranged between the opposite extensions 10; the shell 300 is connected in the middle of the top plate 100 and the bottom plate 200, so that the pressure generated by the lamp weight borne by the top plate 100 can be transmitted to the bottom plate 200 in the most balanced way. Because it is in the center position, it avoids the uneven distribution of force in the transmission process due to the offset of the connection point, reduces the risk of excessive local stress on the base. For example, when the lamp is slightly tilted or the center of gravity is offset due to the lamp head part, the shell 300 connected in the middle can adaptively adjust the force transmission path, ensuring that the entire base is still stably stressed and that there is no sudden increase in pressure on a corner or side, ensuring the stability of the lamp installation. The design of the corner extension 10 is equivalent to expanding the area on the four corners of the base. In actual installation and use, the larger contact area can further reduce the pressure of the base on the support plane, avoiding the base sinking into the soft stage ground under heavy pressure or causing ground wear. Especially for some outdoor performance scenes of temporary stage construction, the ground conditions are complex and diverse, and the extension 10 can adapt to uneven ground to provide more stable support and effectively prevent the lamp from falling due to unstable base, ensuring performance safety. The support column 20 builds an auxiliary support in the vertical direction between the top plate 100 and the extension 10 of the bottom plate 200, and together with the shell 300, the top plate 100 and the bottom plate 200 forms a three-dimensional support network. This multi-dimensional support structure greatly enhances the vertical load capacity of the base and can better cope with the increasing weight demand of the lamp. The support column 20, as a specially designed component to enhance the base structure, has a relatively fixed position and protrudes from the main body structure of the base. When the staff needs to hoist the lamp, they can quickly and accurately find the support column 20 as a gripping point without having to search for a suitable position on the complex shape of the lamp base, saving operation time and improving the efficiency of hoisting operations.

[0028] In an embodiment, the bottom of the bottom plate 200 is provided with a buffer pad 30 opposite the support column 20. During the transportation, installation and occasional falling of the lamp due to accidental circumstances, the buffer pad 30 can play a key role in shock absorption. In addition to protecting the lamp itself, the buffer pad 30 also protects the support surface on which the lamp is placed. In the instant of the lamp falling to the ground, without a buffer measure, secondary shaking will inevitably occur due to inertia, which not only threatens the safety of equipment and personnel around the lamp, but also may cause the lamp to deviate from the intended installation position. The buffer pad 30 can effectively suppress this secondary shaking.

[0029] In an embodiment, the first reinforcing plate 410 is provided with a crimping plate 440 near one side of the bottom plate 200 for fixing the power supply 421. The crimping plate 440 is fixedly connected with the power supply 421 by screws, thereby constructing a mechanical connection structure with high strength and high reliability. Compared with simple buckling or pasting fixation, the screws can provide greater fastening force, effectively preventing the power supply 421 from being displaced or loosened due to vibration, handling or angle adjustment of the lamp during use. The crimping plate 440 cooperates with the first reinforcing plate 410 to effectively protect the power supply 421; the crimping plate 440 is arranged near the bottom plate 200, which is convenient for disassembly from the direction of the bottom plate 200, thereby facilitating replacement or maintenance of the power supply 421; in an embodiment, the crimping plate 440 can also be fixedly connected with the power supply 421 by friction.

[0030] In an embodiment, the second reinforcing plate 430 includes two straight plates 431 arranged in the middle of the first reinforcing plate 410 in a vertical manner; and the outer side of each straight plate 431 away from the other straight plate 431 is provided with an inclined plate 432 sandwiched with the first reinforcing plate 410. The straight plates 431 and the inclined plates 432 are arranged like “pillars” at key positions, thereby greatly improving the bending stiffness of the second reinforcing plate 430 as a whole. When the lamp base bears the heavy pressure from the lamp, especially under eccentric load caused by uneven weight of the lamp head, the straight plates 431 can effectively resist bending deformation and more evenly disperse the vertical downward pressure to the first reinforcing plate 410 and the entire base structure. This bending strengthening effect ensures that the base still maintains a stable shape under severe stress conditions, such as frequent angle adjustment of a large stage lamp or accidental collision, thereby preventing structural distortion and collapse and ensuring the safety and stability of the lamp. From the perspective of three-dimensional space, the second reinforcing plate 430 structure composed of the straight plates 431 and the inclined plates 432 provides overall stable support for the first reinforcing plate 410 and even the entire lamp base.

[0031] In an embodiment, the bottom plate 200 is connected with a hoisting assembly 500; the hoisting assembly 500 is directly connected to the bottom plate 200, thereby realizing integrated integration of the lamp hoisting function.

[0032] In an embodiment, the reinforcing assembly 400 is provided with a clearance slot 450 near one side of the top plate 100; the clearance slot 450 is mainly used for providing clearance for the shaft sleeve 110, thereby ensuring that the reinforcing assembly 400 and the top plate 100 have a relatively flat connection part; the shaft sleeve 110 is a component for connecting the base with the arm part of the lamp, and needs to partially extend into the base to ensure the stability of the structure.

[0033] The above merely describes the embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent transformation or direct or indirect application in the related technical field based on the content of the present application specification and drawings is also included in the patent protection scope of the present application.
