Taking the common circular searchlight as an example, its diameter is generally in the interval of 20-40 centimeters, the lens shell as the outermost key structure is in the shape of cylinder, the bottom is stably connected with the base, and the top is assembled with the light transmission sheet. Because the main body of the cylinder is thin, when connecting with the base and the light transmission sheet, the inner side needs to be additionally provided with a connecting ring to ensure the connection reliability. This scheme is simple and easy to operate in the production and assembly of the connecting ring in the conventional small size lamp scene.

[0003] However, once the lamp size jumps to 60-80 centimeters or even larger specifications, problems follow one after another. First, the production difficulty of the connecting ring increases exponentially, and the traditional process is difficult to accurately and efficiently manufacture large connecting rings. The development of molds and the control of material forming precision are both challenged. Secondly, the increase in size changes the function of the cylindrical main body, which was originally only used as a shell protection. In addition to basic protection, it also needs to bear external force and shoulder the heavy responsibility of structural reinforcement, which puts forward strict requirements on the mechanical properties of materials and the rationality of structural design. Thirdly, the difficulty of waterproof implementation increases, and the change of large-area connecting parts and stress structure easily causes the risk of waterproof sealing failure. It is a great test of overall design and manufacturing process to ensure structural strength and waterproof integrity. CONTENT OF THE UTILITY MODEL

[0028] Embodiment, please refer to Figures 1-5 As shown in the figure:

[0029] A lens shell assembly, comprising a cylindrical main body 100; the main body 100 is generally a cylindrical structure formed by a sheet metal plate; as the basic framework of the lens shell, it provides a protection space for internal components and maintains the overall appearance of the lamp. The top inner side and the bottom inner side of the main body 100 are fixedly connected with a connecting ring 200; the connecting ring 200 is composed of a plurality of connecting ring elements 210; the fitting surface of the connecting ring 200 and the main body 100 is fixedly connected by the first screw 110 arranged on the outer side of the main body 100; the top of the connecting ring element 210 is sealingly connected with the light-transmitting plate 300 through the sealing ring 310. Through the structure of the upper and lower connecting rings 200, the structural stability and bearing capacity of the main body 100 are greatly increased, so that the main body 100 can better serve as a force receiving component; the structure of the connecting ring 200 enhances the structural stability and solves the connection problem of large-size lamps. Compared with the traditional integral connecting ring 200, the production difficulty is reduced under large size, and by setting at the key connection positions (top and bottom), the stress transmitted by the light-transmitting sheet and the base can be effectively dispersed to the main body 100, avoiding stress concentration and causing damage to the components, and ensuring long-term reliable operation of the lamp. The split connecting ring 200 structure greatly reduces the production and manufacturing difficulty, especially for large connecting rings 200 required for large-size lamps. Without complex integral molding process, each connecting ring element 210 can be manufactured by relatively simple mold and processing method, improving production efficiency and product qualification rate. At the same time, in the process of transportation and storage, the spliced elements are more convenient to manage, reduce logistics cost and damage risk, and are more convenient to maintain and replace in the later period. Which part of the element is damaged can be replaced specifically, without the need to replace the connecting ring 200 as a whole. The outer screw fixing method is convenient to operate, and when assembling the lamp, the worker does not need to go deep into the main body to perform complex operation, but can tighten the screw from the outside to realize connection and fastening. On the one hand, it ensures the reliable connection of the connecting ring 200 and the main body 100, so that they can bear force together; on the other hand, it is convenient for the assembly process on the production line, improves the production efficiency, and can be quickly disassembled during subsequent maintenance, shortens the maintenance time. The sealing ring 310 can ensure the waterproof performance of the lamp, and when large-size lamps face the challenge of waterproofing, the sealing ring 310 can effectively fill the fine gap between the connecting ring element 210 and the light-transmitting plate 300, prevent rainwater, moisture and the like from penetrating into the lamp interior, protect the internal electrical elements and optical components from corrosion, short circuit and the like, ensure the normal work of the lamp in complex environments such as humidity and outdoor, and prolong the service life of the lamp.

[0030] In an embodiment, the connecting ring element 210 is provided with a sealing ring groove 230 accommodating the sealing ring 310. The sealing ring groove 230 provides a precise installation space for the sealing ring 310, avoiding displacement, distortion and other conditions of the sealing ring 310 during assembly. It ensures that the sealing ring 310 is always in the ideal sealing position, so that it can tightly fit the connecting ring element 210 and the light-transmitting plate 300, effectively ensuring the stability and reliability of the sealing effect, and preventing waterproof failure caused by mispositioning of the sealing ring 310. Since the sealing ring 310 is stably embedded in the groove, even if it is affected by factors such as temperature changes, vibrations, external pressure and the like during long-term use of the lamp, the sealing ring 310 is not easy to disengage from the original position.

[0031] In an embodiment, the top of the side of the connecting ring element 210 away from the main body 100 is provided with a clamping groove 220 cooperating with the light-transmitting plate 300; the bottom of the clamping groove 220 is provided with a sealing ring groove 230. The clamping groove 220 provides a precise docking position for the light-transmitting plate 300. When assembling the lamp, the worker only needs to gently push the light-transmitting plate 300 along the profile of the clamping groove 220 to achieve preliminary and rapid fixation; the sealing ring groove 230 is arranged at the bottom of the clamping groove 220 to hide the sealing ring 310, which not only utilizes the convenience of the clamping structure to achieve rapid assembly, but also enhances the sealing performance with the help of the sealing ring 310.

[0032] In an embodiment, the sealing ring 310 is an O-shaped sealing ring; the top of the sealing ring 310 exceeds the top of the sealing ring groove 230 in the initial state when it is arranged in the sealing ring groove 230. When the light-transmitting plate 300 is assembled with the connecting ring element 210, the top of the O-shaped sealing ring exceeds the sealing ring groove 230, which can first contact the light-transmitting plate 300, ensuring a tight fit in the initial installation stage and effectively filling the possible small assembly gap; finally, the sealing ring 310 realizes effective waterproof effect after being extruded;

[0033] In an embodiment, the top of the light-transmitting plate 300 is provided with a compression ring 320; the compression ring 320 is fixedly connected with the connecting ring element 210 through the second screw 330 to compress the light-transmitting plate 300. The design of the compression ring 320 cooperating with the second screw 330 provides additional fastening force for the light-transmitting plate 300; when the compression ring 320 compresses the light-transmitting plate 300, it will further extrude the sealing ring 310 between the light-transmitting plate 300 and the connecting ring element 210, prompting the sealing ring 310 to better fill the gap, and the compression ring 320 can also effectively and uniformly distribute the pre-tightening force of the second screw 330 to the compression ring 320, thereby uniformly distributing the stress of the sealing ring 310 everywhere, avoiding excessive local stress.

[0034] In an embodiment, the top of the compression ring 320 is fixedly provided with a protective block 340; the protective block 340 can provide direct physical shielding for the light-transmitting plate 300 and the components below, such as the connecting ring element 210, the sealing ring 310, etc. During the transportation and installation of the lamp, it is inevitable to encounter external collisions and scratches. The protective block 340 acts as the first barrier and preferentially bears the impact force, preventing hard objects from directly impacting the compression ring 320 and damaging the light-transmitting plate 300, thereby avoiding problems such as breakage and scratches of the light-transmitting plate 300 that affect the optical performance of the lamp, and ensuring the integrity of the appearance and normal lighting function of the lamp. When the lamp is subjected to a large external impact, such as falling or strong vibration, the protective block 340, due to its own mass and strength, can disperse the impact force concentrated on a point of the compression ring 320 to a larger area in an instant. This helps to reduce the situation of local overload of the compression ring 320, prevents deformation of the compression ring 320 and loosening of the screws, maintains the stable compression state of the compression ring 320 on the light-transmitting plate 300, ensures the stability of the entire lens shell assembly structure, and reduces the risk of damage to the internal precision components of the lamp.

[0035] In an embodiment, the connecting ring element 210 is provided with a fixing hole 240 cooperating with the second screw 330; the fixing hole 240 is located between the light-transmitting plate 300 and the main body 100; by arranging the fixing hole 240 between the light-transmitting plate 300 and the main body 100, the space of the intermediate structure of the connecting ring element 210 is fully utilized. Compared with opening holes in other parts, it avoids occupying valuable space inside or outside the lamp, making the overall structure of the lamp more compact. In the design of large-size lamps, every inch of space optimization is crucial, and this layout helps to reduce the volume of the lamp, facilitating transportation, installation, and arrangement in different scenarios;

[0036] In an embodiment, the connecting ring element 210 includes a first cooperating block 211 formed by extending the bottom of one end outward, and a second cooperating block 212 formed by extending the top of the other end outward; adjacent connecting ring elements 210 are fixedly connected by cooperating the first cooperating block 211 with the second cooperating block 212 through screws. The design of the first cooperating block 211 and the second cooperating block 212 greatly simplifies the splicing process between the connecting ring elements 210. Workers only need to align the first cooperating block 211 of an adjacent connecting ring element 210 with the second cooperating block 212, gently engage, and then fix with screws. The operation is intuitive and simple, without the need for complex positioning molds or high-precision alignment processes. The first cooperating block 211 and the second cooperating block 212 cooperatively provide a precise docking reference for adjacent connecting ring elements 210, effectively avoiding problems such as misalignment and deviation during splicing. When the lamp is subjected to force, the force is transmitted through the connecting ring element 210. The connection area of the first cooperating block 211 and the second cooperating block 212 can disperse the concentrated force to each splicing part, avoiding stress concentration on a few points, and making the entire connecting ring 200 bear force more evenly.

[0037] In an embodiment, two screws are used to ensure the stability of the connection between the adjacent connecting ring elements 210, and to prevent rotation misalignment between them;

[0038] In an embodiment, the connecting ring element 210 is provided with a protruding part 250 at the end away from the main body 100, which is fixedly connected to the base. The protruding part 250 provides an additional contact and fixing area between the connecting ring element 210 and the base. Compared with direct contact on a plane, the protruding part 250 can be embedded in the corresponding groove or clamping groove on the base to form a close-fitting structure similar to a mortise and tenon joint, which is further reinforced by screws or other connecting parts, and can effectively resist the displacement force of the lamp in the horizontal direction, such as sliding or rotating caused by factors such as vibration of the installation site of the lamp, wind shaking, etc., to effectively limit the displacement, ensuring the stability of the connection between the connecting ring 200 and the base, and maintaining the stability of the overall structure of the lamp. When the lamp is subjected to pressure from above, such as self-weight, additional weight of installation accessories or external force impact, the protruding part 250 acts as a force transmission node and can more evenly distribute the pressure to the base. During the assembly of the lamp, the matching features of the protruding part 250 and the base have a clear guiding and positioning effect.

[0039] The above is only an embodiment of the present application, and does not limit the patent range of the present application. Any equivalent transformation, direct or indirect application in related technical fields based on the content of the present application specification and drawings is also included in the patent protection range of the present application.
