Description

TECHNICAL FIELD

[0001] The utility model relates to the field of lamps and lanterns especially, relate to a high strength lamp support frame. BACKGROUND

[0002] In the professional field of searchlight and stage lighting, limited by specific function realization demand and established structure frame system, the stage lamp arm is generally designed into U-shaped structure at present. In terms of shell split-molding and subsequent assembly combination link, the traditional processing means is to split the support arm shell along the center position, and then form two independent U-shaped shell components, and then carry out the assembly process based on this. However, this seemingly conventional combination mode actually has a series of tricky problems.

[0003] From the physical size dimension of the product, the overall size of the stage lamp assembled by the traditional process is large, which not only occupies too much space in the transportation and storage process, adds cost and inconvenience to the logistics and warehousing link, but also increases the difficulty of placing large lamps in actual installation scenes, especially in the stage environment with limited space, and the staff needs to spend a lot of energy to adjust the position and angle, and the subsequent maintenance, component replacement and other operations are also a headache.

[0004] In terms of structural stability, since the U-shaped shell is spliced after splitting, the connecting part is naturally weak compared to the integrated forming structure, and is prone to deformation when used for a long time, frequently moved or subjected to slight external force impact, which directly affects the accuracy of the illumination angle of the lamp and the stability of the overall light and shadow effect, and brings noticeable interference to the visual presentation of the stage performance.

[0005] The joint form of the traditional process is single, and limited by manufacturing precision and assembly method, it is almost impossible to achieve uniform and fine joint effect, making the appearance of the lamp rough and simple from the visual aspect.

[0006] On the other hand, the lamp industry is moving towards large-scale, and as the size of the lamp increases, the weight of the lamp also increases rapidly. In the traditional structure system, mainly rely on sheet metal parts as support parts to build the lamp skeleton, and the material properties of the sheet metal parts determine that there is an upper limit to its rigidity and carrying capacity. Once the weight of the lamp exceeds a certain threshold, the sheet metal support structure cannot effectively resist the pressure brought by gravity, and then obvious and visible deformation occurs. This not only destroys the integrity of the appearance of the lamp, but also causes displacement and extrusion risk to the internal precise optical components and electronic elements, seriously threatening the normal function of the lamp and the service life.

[0027] Embodiment, please refer to Figs. 1-3 As shown in the drawings:

[0028] The utility model provides a high -strength lamp support frame, including support framework 100 and support shell 200, support shell 200 is covered in support framework 100 outside, support shell 200 includes the first side plate 210 of U type of relative interval arrangement, first side plate 210 includes the arm portion 212 of the connection of the top 211 of two first side plates 210, and the horizontal plate 220 is connected between the top of the top 211 of two first side plates 210, and the inner side and the outside of arm portion 212 are connected with inner arm plate 230 and outer arm plate 240 respectively, support framework 100 is connected by the U type structure of several square tubes, and the modularization of square tube combination has very high structural compactness, compared with traditional sheet metal support structure, greatly strengthens structural strength, guarantees that support frame can be applicable to the large -size lamp, further, the support framework 100 of square tube can provide relatively flat mounting surface, to realize with the face contact of first side plate 210, to effectively strengthen the structural strength of first side plate 210, first side plate 210 can be integrally cut into shape, can utilize the existing conventional process production and manufacture, and first side plate 210 cooperates with square tube and effectively solves the problem of large -area sheet metal easy deformation, difficult installation, assembly precision difference in the prior art.

[0029] The support shell 200 is wrapped outside the support framework 100, and each component of the support shell 200 is closely attached to the support framework 100, especially the two first side plates 210 in the U shape, which form a stable and regular closed space through precise connection with the horizontal plate 220, the inner arm plate 230 and the outer arm plate 240. In terms of the support shell 200, the horizontal plate 220 connected between the top of the horizontal part 211 of the two first side plates 210 enhances the bending resistance in the horizontal direction, uniformly disperses the stress on both sides, and prevents local deformation caused by excessive stress on a single side. The inner arm plate 230 and the outer arm plate 240 are respectively connected to the inner and outer sides of the arm part 212, which not only increases the thickness of the arm part 212 and improves its ability to resist external force impact, but also restricts the deformation trend of the arm part 212 in all directions. Therefore, the lamp can still maintain structural integrity and ensure accurate and stable illumination angle when facing frequent handling, long-term vibration and accidental collision, thereby providing reliable light and shadow protection for stage performance.

[0030] In an embodiment, the outer arm plate 240 comprises a first outer arm plate 241 and a second outer arm plate 242 connected in sequence; the second outer arm plate 242 is arranged close to the horizontal part 211; and the first outer arm plate 241 is arranged away from the horizontal part 211. The split structure can adapt to different bending edges 243 on the first side plate 210, facilitating installation and manufacturing, and the split structure is also easier to transport and package.

[0031] In an embodiment, the first outer arm plate 241 is internally provided with a reinforcing framework 250 fixedly connected with the support framework 100. In terms of structural reinforcement, the reinforcing framework 250 closely cooperates with the support framework 100, which can be made of high-strength alloy material or specially heat-treated steel material, and has excellent rigidity. When the lamp encounters extreme working conditions such as strong vibration and accidental impact, the reinforcing framework 250 can share part of the pressure borne by the support framework 100, evenly disperses the external force to a larger range through multi-point fixed connection, effectively inhibits the bending and twisting deformation of the support framework 100, further improves the reliability of the entire lamp structure, and ensures that the light illumination angle is still accurate and correct under harsh conditions. From the perspective of space utilization, the structural design of the reinforcing framework 250 expands the available space inside the first outer arm plate 241, and the enlarged internal space provides ample channels for wiring, so that technicians can comfortably classify and regularly arrange the wires, reduce line loss and short circuit hazards, and also facilitate subsequent maintenance and upgrading. Moreover, for some small-sized auxiliary equipment such as heat dissipation devices and intelligent control modules that need to be installed inside the lamp, the newly added space also provides an ideal accommodation place.

[0032] In an embodiment, the second outer arm plate 242 is provided with a folded edge 243 on both sides towards the arm portion 212; the folded edge 243 is fixedly connected with the arm portion 212 and increases the accommodation space inside the second outer arm plate 242. The presence of the folded edge 243 is equivalent to adding an additional reinforcing rib to the second outer arm plate 242, thereby being able to improve the structural strength;

[0033] In an embodiment, the inner arm plate 230 is provided with a through hole 231 for the rotating shaft assembly to pass through.

[0034] In an embodiment, the lateral portion 211 is fixedly connected with a reinforcing plate 213 outside. The lateral portion 211 is a key load-bearing part of the support shell 200, bearing the weight of the lamp itself and additional forces generated due to movement and collision. The reinforcing plate 213 is fixedly connected with the lateral portion 211 and has excellent bending and compression resistance.

[0035] In an embodiment, the support framework 100 is fixedly connected with the first side plate 210 through surface contact and screws. The surface contact design ensures that the support framework 100 and the first side plate 210 are in large-area contact, which can more evenly disperse the force compared with point contact or line contact. When the lamp bears its own weight, especially large and heavy stage lamps, or is subjected to external force impact during transportation and installation, the force can be effectively transmitted to the entire support framework 100 through the large-area surface contact, avoiding stress concentration in a small local area and reducing the risk of structural damage caused by local overload, such as indentation of the first side plate 210 and deformation of the first side plate 210, thereby effectively ensuring the stability of the overall structure of the lamp and maintaining the precise light projection angle to ensure that the stage performance is not affected.

[0036] In an embodiment, the bottom of the support framework 100 is provided with a drainage hole 110. The drainage hole 110 can prevent the accumulation of water inside the lamp and ensure that the inside of the lamp can dry quickly after being rained on.

[0037] The above description is only an embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent transformation or direct or indirect application in related technical fields based on the content of the present application is also included in the patent protection scope of the present application.
