The lighting direction and coverage range of the search light usually need to be adjusted in pitch angle through the internal or external connecting rod mechanism to adapt to the irradiation requirements of different pitch angles.
[0003] A common search light structure, such as the "ultra-bright search light device" disclosed in Chinese Utility Model Patent No. CN218645298U, mainly includes a lamp barrel, a cloud platform and a support rod module. The support rod module includes a connecting rod, a support rod and a traction plate. One end of the support rod is fixedly connected with the bottom of the lamp barrel, and the other end is sleeved in the middle of the connecting rod. One end of a pair of traction plates is hingedly connected with both ends of the connecting rod, and the other end of the pair of traction plates is respectively connected with a pair of cloud platform shafts. When the cloud platform shaft rotates, the cylinder body rotates up and down. At present, the mainstream search light generally adopts the fixed connecting rod structure in the above-mentioned patent to realize the rotation of the lamp body within the preset pitch angle range, that is, to realize the vertical rotation adjustment. However, in the long-term actual application, installation and maintenance process, the technical personnel in the field found that the above-mentioned traditional fixed connecting rod structure has the following technical defects: the angle range cannot be conveniently adjusted to expand or narrow when the entire lamp body is adjusted in vertical rotation angle; during installation and debugging, it often needs to be repeatedly disassembled and debugged to meet the angle range. In view of the above-mentioned prior art, the present applicant has made beneficial design, and the technical scheme to be introduced below is generated in this background. SUMMARY
[0004] The purpose of the present application is to provide an adjustable connecting rod structure for a search light with simple structure, which can be simply and quickly adjusted to expand the universality.
[0005] The objective of this invention is achieved by providing an adjustable linkage structure for a searchlight. The searchlight includes a lamp body and a pan-tilt unit supporting the lamp body. The adjustable linkage structure includes a straight connecting rod, a central support rod, and side support plates. One end of the central support rod is fixedly connected to the bottom of the lamp body, and the other end is sleeved on the middle of the straight connecting rod. There is a pair of side support plates, symmetrically arranged on both sides of the pan-tilt unit. Each side support plate includes a front side plate and a rear side plate. The front side plate has an annular hole at its front end, through which a side plate fixing shaft for rotatably connecting with the side wall of the pan-tilt unit is installed. The front side plate has multiple front adjustable holes spaced apart along its length at its rear end. The rear side plate has a rear adjustable hole at its front end corresponding to the front adjustable holes. Fasteners connect different front and rear adjustable holes to allow the side support plates to have different lengths. The rear ends of the pair of rear side plates are respectively hinged to the two ends of the straight connecting rod.
[0006] In a specific embodiment of the present invention, the front adjustable hole and the rear adjustable hole are arranged in two rows and multiple columns.
[0007] In another specific embodiment of the present invention, the front end of the pair of rear side plates is located inside the rear end of the pair of front side plates. The front adjustable hole is a through hole, and the rear adjustable hole is a threaded hole. The screw passes through the front adjustable hole and is screwed into the rear adjustable hole to fix the front side plate and the rear side plate together.
[0008] In another specific embodiment of the present invention, there are four annular holes arranged in a square pattern, and the side plate fixing shaft has a fixing seat. The fixing seat is provided with threaded fixing holes corresponding to the annular holes. Screws pass through the annular holes and are screwed into the threaded fixing holes to fix the side plate fixing shaft to the front side plate.
[0009] Compared with existing technologies, this invention, due to its aforementioned structure, offers the following advantages: It allows for rapid and continuous adjustment of the lamp's vertical pitch angle range on-site, significantly improving ease of use and efficiency, enhancing the product's versatility and adaptability to complex application scenarios such as varying installation heights and illumination distances; the annular hole design facilitates the connection between the side support plate and the side plate fixing shaft, enabling fine-tuning of the upper and lower support points of the side support plate during installation and debugging, thereby fine-tuning the lamp's vertical rotation range; and the debugging phase eliminates the need for repeated disassembly, trial assembly, and parts replacement, significantly shortening installation time and reducing the skill requirements for operators, effectively saving installation, debugging, and maintenance costs.

[0012] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the description of the embodiments is not a limitation on the technical solution. Any formal but not substantive changes made based on the concept of the present invention should be considered within the scope of protection of the present invention.
[0013] In the following description, all directional (or orientational) concepts involving up, down, left, right, front, and back refer to the position of the figure being described, and are intended to facilitate public understanding. Therefore, they should not be construed as a special limitation on the technical solution provided by this invention.
[0014] This invention relates to an adjustable linkage structure for searchlights, which increases the adjustability of the linkage structure based on the original linkage structure, and realizes multi-degree-of-freedom adjustment of the lamp body through mechanical linkage, making it suitable for lighting devices in rescue, industrial inspection, search and rescue and other scenarios.
[0015] See Figure 1This invention relates to an adjustable linkage structure for a searchlight. The searchlight includes a lamp body and a pan-tilt unit supporting the lamp body. The adjustable linkage structure includes a straight connecting rod 1, a central support rod 2, and side support plates 3. One end of the central support rod 2 is fixedly connected to the bottom of the lamp body, and the other end is sleeved on the middle of the straight connecting rod 1. There is a pair of side support plates 3, symmetrically arranged on both sides of the pan-tilt unit. Each side support plate 3 includes a front side plate 31 and a rear side plate 32. The rear ends of the pair of rear side plates 32 are respectively hinged to the two ends of the straight connecting rod 1. The straight connecting rod 1 also has side plate end caps 11 at both ends to limit the movement of the rear side plates 32. The front ends of a pair of rear side plates 32 are located inside the rear ends of a pair of front side plates 31. The front side plates 31 have multiple front adjustable holes 312 spaced apart along their length at their rear ends. The rear side plates 32 have rear adjustable holes 321 at their front ends corresponding to the front adjustable holes 312. The front adjustable holes 312 are through holes, and the rear adjustable holes 321 are threaded holes. Screws pass through the front adjustable holes 312 and are screwed into the rear adjustable holes 321, thus fixing the front side plates 31 and rear side plates 32 together. To ensure the reliability of the connection and the support of the side support plate 3, in this embodiment, the number of front adjustable holes 312 and rear adjustable holes 321 are the same, arranged in two rows and five columns. By connecting different columns of front adjustable holes 312 and rear adjustable holes 321, the side support plate 3 can have different lengths, thereby increasing or decreasing the range of vertical rotation angle of the lamp body. The side support plate 3 adopts the above-mentioned detachable adjustment structure, which allows for convenient adjustment of the vertical rotation angle range of the lamp body on site, thereby increasing versatility and adapting to various searchlights; it also avoids the need for repeated disassembly and adjustment during installation and debugging to meet the angle range requirements.
[0016] Furthermore, the front side plate 31 has an annular hole 311 at its front end, through which a side plate fixing shaft 4 for rotatable connection with the gimbal side wall is installed. Preferably, there are four annular holes 311, arranged in a square pattern. The side plate fixing shaft 4 has a fixing seat 41, and the fixing seat 41 has a threaded fixing hole 411 corresponding to the annular hole 311. Screws pass through the annular hole 311 and are screwed into the threaded fixing hole 411 to fix the side plate fixing shaft 4 to the front side plate 31. The design of the annular hole 311 increases the arc distance between the connecting hole of the front side plate 31 and the side plate fixing shaft 4, facilitating the connection between the front side plate 31 and the side plate fixing shaft 4. This allows for fine adjustment of the upper and lower support points of the front side plate 31 during installation and debugging, thereby enabling fine adjustment of the vertical rotation range of the lamp body.
[0017] This invention offers high adjustability, making the searchlight linkage structure versatile and applicable to various searchlights. The design boasts high utilization and low processing costs, thus achieving the invention's objective.
