Description

Technical Field

[0001] This utility model relates to the technical field of lighting fixtures, specifically to a lamp holder fixing structure. Background Technology

[0002] In the current context of rapid development in the global lighting industry, lighting products are iterating and upgrading towards diversification, personalization, and efficiency. Different application scenarios have placed differentiated requirements on the external dimensions of lighting fixtures. This diversified market demand has directly driven the continuous expansion of lighting product models. Different models and wattages of lighting fixtures differ significantly in terms of appearance and other aspects, resulting in an industry status quo of "one solution for one lighting fixture." However, as the core component for lighting fixture installation and angle adjustment, the design and manufacturing of lighting fixture brackets have long faced many industry pain points, severely restricting the industry's development efficiency.

[0003] First, existing lamp brackets and angle adjustment structures are generally deeply coupled with specific lamp bodies, lacking standardized design. Due to the differences in mounting surface dimensions, fixing methods, and stress requirements of different lamps, manufacturers need to design a separate bracket structure for each new lamp, from structural modeling and mechanical simulation to mold development and sample testing. The entire process is lengthy and costly.

[0004] Secondly, the lack of component interchangeability increases the difficulty of supply chain management and leads to persistently high inventory pressure. For lighting manufacturers, components such as brackets and angle adjustment parts for different models of lights are not interchangeable and need to be purchased, stored, and managed separately. This not only increases procurement costs but also causes a surge in inventory and a decrease in inventory turnover. At the same time, for upstream component suppliers, non-standardized demand leads to small production batches, frequent line changes, and low production efficiency, further driving up component production costs, which are ultimately passed on to the entire industry chain.

[0005] Furthermore, the reliability and adaptability of existing adjustment structures are insufficient. Some traditional brackets use simple bolt fixing to achieve angle adjustment, lacking effective positioning and locking structures. Over long-term use, this can easily loosen, causing the illumination angle to shift and affecting the lighting effect. This risk of loosening is particularly pronounced in vibrating environments (such as industrial plants and transportation hubs) or outdoor settings, and may even pose safety hazards. In addition, the adaptation methods of existing structures are relatively limited. When the mounting surface structure of the luminaire is slightly adjusted, the entire bracket system often needs to be redesigned, failing to achieve flexible adaptation and restricting the iterative upgrade space for luminaire products.

[0006] As competition intensifies in the lighting industry, manufacturers are increasingly eager to reduce costs, increase efficiency, and enhance supply chain flexibility. Against this backdrop, the industry urgently needs a standardized, reliable, and highly adaptable lamp holder fixing structure. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a lamp holder fixing structure, which solves the problems mentioned in the background section. Technical solution

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a lamp holder fixing structure for connecting a lamp and a U-shaped bracket, comprising a fixing plate, an outer serrated washer, and a graduated toothed plate; characterized in that: the fixing plate has a circular cross-section, with a fixing through hole A at the center, and a circularly distributed fixing tooth at the outer edge of a circular surface of the fixing plate; a plurality of fixing through holes B are distributed circumferentially between the fixing through hole A and the fixing tooth; the serrations of the outer serrated washer are inclined outward, and a fixing through hole A is provided at the center of the outer serrated washer; the graduated toothed plate is a stepped cylinder, with a fixing through hole A at the center, and a graduated tooth in an arc shape that matches and meshes with the fixing tooth at the outer edge of a circular surface of the graduated toothed plate; the notch of the arc-shaped graduated tooth forms an installation space; a plurality of fixing posts are distributed circumferentially between the fixing through hole A and the graduated tooth.

[0009] Preferably, the lamp holder fixing structure consists of two sets, symmetrically arranged at both ends of the lamp.

[0010] Preferably, each end of the lamp has a plurality of positioning threaded holes A that match the fixed through hole B distributed along the circumference, and the lamp is also provided with positioning threaded holes B that match the fixed through hole A.

[0011] Preferably, the fixing through hole B and the positioning threaded hole A are connected by an internal hex bolt to fix the fixing plate to the lamp.

[0012] Preferably, each cross-section at both ends of the bracket is circular, and its diameter matches the inner diameter of the scale teeth.

[0013] Preferably, each of the two ends of the bracket has several fixing through holes C that match the fixing column distributed along the circumference, and a fixing through hole A is also provided at the center of the bracket.

[0014] Preferably, the fixing through hole A of the fixing plate, the outer serrated washer, the graduated toothed plate, and the bracket are connected to the positioning hole B of the lamp by a fixing bolt.

[0015] This utility model provides a lamp holder fixing structure, which has the following beneficial effects: 1. Modularize the angle adjustment function and standardize the mass production of core components (scale toothed disc, bracket, external serrated washer, etc.). Different models of lamps only need to be adapted to the fixing plate to be used, which greatly reduces the cost of repeated design, mold development and material management, simplifies the inventory structure, improves production efficiency and supply chain response speed, and promotes the development of universal parts in the industry.

[0016] 2. Each component achieves balanced force through precise size matching and multi-directional connection. The fixing teeth of the fixed plate mesh with the scale teeth of the scale plate for positioning. The fixed column and through hole cooperate to enhance structural stability, effectively avoid stress concentration, ensure durability in complex scenarios such as vibration and outdoor environments, and extend service life.

[0017] 3. The mounting plate can be flexibly adjusted in shape, size and fixing method according to the lamp body structure, while the core module remains unchanged, adapting to lamps of different power and shape; the assembly process only requires fixing with hexagonal bolts and fixing bolts, the steps are simple, no complicated tools are required, and the bolts can be loosened to rotate and position when adjusting the angle, making the operation convenient and efficient.

These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0021] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0022] Example 1: Please refer to Figures 1 to 7 A lamp holder fixing structure for connecting a lamp (5) to a U-shaped bracket (6) includes a fixing plate (1), an outer serrated washer (2), and a graduated toothed plate (3); the fixing plate (1) has a circular cross-section and a fixing through hole A (4) in the center. A circularly distributed fixing tooth (101) is provided on the outer edge of a circular surface of the fixing plate (1). Several fixing through holes B (102) are distributed circumferentially between the fixing through hole A (4) and the fixing tooth (101) on the fixing plate (1); the serrations of the outer serrated washer (2) are inclined... The outer sawtooth washer (2) is obliquely outward and has a fixed through hole A (4) in the center; the scale toothed disc (3) is a stepped cylinder with a fixed through hole A (4) in the center. The outer edge of a circular surface of the scale toothed disc (3) has scale teeth (301) that match and mesh with the fixed teeth (101) and are distributed in an arc shape. The notch of the arc-shaped scale teeth (301) forms an installation space (302). The scale toothed disc (3) has several fixed posts (303) distributed around the circumference between the fixed through hole A (4) and the scale teeth (301).

[0023] The fixed plate (1) serves as the interface between the lamp (5) and the core adjustment module, ensuring a stable connection between the core module and the lamp body. The inclined serrations on the outer serrated washer (2) will scratch the paint on the bracket and the fixed plate when tightened, allowing the static electricity generated by the structure to be conducted through its external ground wire (not shown in this embodiment), thus timely discharging the static electricity generated during the use of the lamp, preventing the accumulation of static electricity from damaging the electronic components of the lamp, and ensuring safe use. The scale toothed plate (3) serves as the core component for angle adjustment, and the meshing of the scale teeth (301) and the fixed teeth (101) enables the positioning and locking of the angle settings.

[0024] The lamp holder fixing structure consists of two sets, symmetrically arranged at both ends of the lamp (5). The symmetrical design makes the structure more stable.

[0025] The lamp (5) has several positioning threaded holes (501) that match the fixed through hole (102) at each end along the circumference. The lamp (5) is also provided with positioning threaded holes (502) that match the fixed through hole (4).

[0026] The fixed through hole B (102) and the positioning threaded hole A (501) are connected to an internal hex bolt (7) to fix the fixed plate (1) to the lamp (5).

[0027] Each of the two ends of the bracket (6) has a circular cross-section, the diameter of which matches the inner diameter of the scale teeth (301). The rear end of the bracket (6) is accommodated within the installation space (302).

[0028] Each end of the bracket (6) has several fixing through holes (601) that match the fixing posts (303) distributed around its circumference. The bracket (6) also has a fixing through hole (4) at its center. The fixing through holes (601) cooperate with the fixing posts (303) of the scale gear (3) to achieve connection with the core adjustment module. The circular end design ensures smooth rotation during angle adjustment, and the size matching with the scale gear (3) ensures connection stability.

[0029] The fixing through holes A (4) of the fixed disk (1), the outer serrated washer (2), the scale toothed disk (3), and the bracket (6) are connected to the positioning hole thread B (502) of the lamp (5) by fixing bolts (8). The fixing bolts (8) are the core fasteners of the overall structure. They pass through the fixing through holes A (4) of the scale toothed disk (3), the bracket (6), and the outer serrated washer (2) in sequence, and are threadedly connected to the positioning hole thread B (502) of the lamp (5), locking the fixed disk (1), the outer serrated washer (2), the scale toothed disk (3), the bracket (6) and the lamp (5) into one unit. When loosened, the bracket (6) can drive the scale toothed disk (3) to rotate and adjust the angle. After locking, the overall structure is fixed to ensure stability during use.

[0030] A circular scale is provided on another circular surface of the graduated gear disc (3). The angle can be precisely controlled by using the scale.

[0031] In this embodiment, the number of fixed through holes B (102), positioning threaded holes A (501) and internal hex bolts (7) is 4; the number of fixed through holes C (601) and fixed posts (303) is 3. The above only represents the selection of this embodiment and is not the only limitation.

[0032] Working process: According to the structure and size of the target lamp (5), select a suitable fixing plate (1), use the internal hex bolt (7) to pass through the fixing through hole B (102) of the fixing plate (1) and the positioning threaded hole A (501) of the lamp (5) in sequence, and firmly install the fixing plate (1) in the predetermined position of the lamp (5) to ensure that the fixing plate (1) is installed flat and without looseness.

[0033] Align the installation space (302) of the scale toothed disc (3) with the rear end of the bracket (6), so that the fixing post (303) on the scale toothed disc (3) passes precisely through the fixing through hole (601) of the bracket (6), and achieve the initial positioning of the scale toothed disc (3) and the bracket (6); then set the outer serrated washer (2) against the other side of the bracket (6), so that the fixing bolt (8) passes through the fixing through hole (4) of the scale toothed disc (3), the bracket (6), and the outer serrated washer (2) in sequence, and complete the pre-assembly. At this time, the fixing bolt (8) is not fully tightened.

[0034] Align the pre-assembled core module (scale toothed disc (3), bracket (6), outer serrated washer (2), fixing bolt (8)) with the fixing plate (1) that is fixed on the lamp (5). Screw the threaded end of the fixing bolt (8) into the positioning hole thread (502) of the lamp (5) through the fixing through hole A (4) in the center of the fixing plate (1). Slowly tighten until the module and the fixing plate (1) are initially in contact, ensuring that the fixing tooth (101) and the scale tooth (301) are in a meshing state.

[0035] Loosen the fixing bolt (8) until the scale toothed plate (3) can rotate freely. According to the scale on the surface of the scale toothed plate (3), rotate the bracket (6) to drive the scale toothed plate (3) to rotate, so that the lamp (5) can be adjusted to the required illumination angle. At this time, the fixing teeth (101) of the fixing plate (1) and the scale teeth (301) of the scale toothed plate (3) are precisely engaged to achieve angle positioning.

[0036] Tighten the fixing bolts (8) clockwise with the tool so that the bracket (6) is firmly clamped between the scale toothed plate (3) and the outer sawtooth washer (2). All parts fit tightly together, and the fixing teeth (101) and the scale teeth (301) are fully engaged and locked, completing the installation of the entire lamp bracket fixing structure. If the angle needs to be adjusted again later, repeat the above steps.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
