Description

Technical Field

[0001] This utility model relates to the field of modular desk lamp technology, and in particular to a modular detachable desk lamp. Background Technology

[0002] In modular desk lamps, the adjustability and environmental adaptability of the light source have a significant impact on visual comfort and work efficiency. To achieve precise and flexible adjustment and control of lighting effects, a multi-functional lighting device is typically required. This device usually includes core functional units such as a light source module, a dimming mechanism, and a heat dissipation structure. Especially since the number of light sources required varies in different environments, developing a modular, efficient, and user-friendly desk lamp lighting device has become an important direction for technological improvement.

[0003] In existing technologies, the connection methods between components used in modular desk lamps generally include threaded connections, positioning pins, or screw fastening structures. Specifically, modules such as lamp holders, lamp arms, and lampshades often use methods such as threaded tightening, multiple pin alignment and locking, or multi-point fixing with small screws to achieve physical connections; at the same time, the design must consider both connection stability and overall aesthetics. In actual assembly, different functional modules usually require precise alignment of interfaces and the individual tightening, insertion, or screwing of screws. When combining multiple modules or adjusting the structure, multiple connection points need to be repeatedly operated with the aid of tools. Furthermore, the connection mechanisms are often designed with fixed directions or require precise operation, making the assembly process time-consuming, labor-intensive, and cumbersome, failing to achieve the user's expectation of quickly assembling several modular components together.

[0004] However, existing modular desk lamps still have certain problems in practical applications. On the one hand, different environments require different numbers of light sources to be connected, and the existing structure cannot be quickly disassembled and replaced, which greatly affects the assembly efficiency. On the other hand, they cannot be folded down, which can easily cause damage to the lamp body. The above problems reduce the operational efficiency and safety of modular desk lamps, and it is urgent to optimize the structural design. Therefore, a modular detachable desk lamp is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a modular detachable table lamp, which aims to improve the problem of the inability to quickly disassemble and assemble in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a modular detachable desk lamp, including a housing, a quick-change component inside the housing, and an adjustment component on the top of the housing;

[0007] The quick-change assembly includes a connecting rod, the outer wall of which slides inside the outer shell. One end of the connecting rod is fixedly connected to a push post. A spring is sleeved on the outer wall of the connecting rod, one end of which is fixedly connected to the push post, and the other end of which is fixedly connected to the outer wall of the outer shell. One end of the connecting rod is fixedly connected to a fixing block. A locking block is fixedly connected to the outer wall of the outer shell. The locking block has a rotating groove and a fixing groove inside. The outer shell has an inner groove. The outer wall of the fixing block slides inside the inner groove, inside the fixing groove, and inside the rotating groove.

[0008] As a further description of the above technical solution:

[0009] The adjustment component includes a fixing bar, the bottom end of which is fixedly connected to the top of the outer shell, and a rotating column is rotatably connected to the top of the fixing bar.

[0010] As a further description of the above technical solution:

[0011] The top of the fixing strip is rotatably connected to a second rotating column, the inside of which a first connecting column is fixedly connected, and the outer wall of the first connecting column is fixedly connected to a lamp body.

[0012] As a further description of the above technical solution:

[0013] The first connecting column has a sliding groove inside, and the second connecting column is rotatably connected inside the first rotating column. As a further description of the above technical solution:

[0014] One end of the connecting column is fixedly connected to a push block, and the outer wall of the push block slides in the sliding groove.

[0015] As a further description of the above technical solution:

[0016] A pull rod is slidably connected inside the connecting column, a locking block is fixedly connected to one end of the pull rod, and a limit block is fixedly connected to the top of the locking block.

[0017] As a further description of the above technical solution:

[0018] The outer wall of the pull rod is fitted with a second spring. One end of the second spring is fixedly connected to the first connecting post, and the other end of the second spring is fixedly connected to the outer wall of the locking block.

[0019] As a further description of the above technical solution:

[0020] The connecting column has an inner groove, and the outer wall of the locking block slides inside the inner groove.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the push post is first pressed down. When the fixing block reaches the designated position, the push post is rotated. When it reaches the designated position, the push post is released. Under the rebound action of the spring, the fixing block is driven into the fixing groove, thereby fixing the push block to the outer shell. After pressing down the push post, the push post is rotated to remove the fixing between the outer shell and the push block, thereby removing the push block. This achieves the effect of quick disassembly, solves the problem that the modular desk lamp power supply cannot be quickly disassembled and assembled during operation, and improves the convenience of the excitation and demagnetization tool.

[0023] 2. In this utility model, pulling the pull column cancels the fixing of the locking block to the push block, pressing the connecting column one downward, retracting the connecting column one into the outer shell, pulling the connecting column one upward, and under the rebound action of the second spring, pushing the locking block into the push block, thereby fixing the locking block, achieving the effect of retracting the connecting column one, solving the problem that the modular table lamp power supply cannot be retracted into the lamp body when working, and improving the safety of the excitation and demagnetization tool.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-2 The present invention provides an embodiment of a modular detachable desk lamp, including a housing 1 for integrating a lighting function module, providing electrical protection and structural support to ensure safe use, a quick-change component inside the housing 1 for quick disassembly and assembly, and an adjustment component on the top of the housing 1 to protect the lamp body 21 from damage during storage.

[0034] The quick-change assembly includes a connecting rod 4, which enables the rapid installation and removal of the lighting module through mechanical linkage. The outer wall of the connecting rod 4 slides inside the outer shell 1. One end of the connecting rod 4 is fixedly connected to a push post 2, whose raised design enhances the pressing feel and reduces operating force. A spring 3 is fitted onto the outer wall of the connecting rod 4 to provide elastic restoring force. After release, it automatically returns to its locked position, ensuring the stability of the lamp body 21 connection. One end of the spring 3 is fixedly connected to one end of the push post 2, and the other end is fixedly connected to the outer wall of the outer shell 1. A fixing block 5 is fixedly connected to one end of the connecting rod 4 to perform a three-rail locking action, which is achieved through mechanical interlocking. Due to the weight of the lamp body 21, a locking block 9 is fixedly connected to the outer wall of the outer shell 1 to provide a precision locking structure. The integrated rotating groove 6 and fixing groove 7 double track system ensure the positioning accuracy of the module. The locking block 9 has a rotating groove 6 inside for rotating and disassembling the fixing block 5. The locking block 9 has a fixing groove 7 inside for forming the final locking position, providing tensile strength and preventing accidental fall-off. The outer shell 1 has an inner groove 8 inside for retracting the fixing block 5. The outer wall of the fixing block 5 slides inside the inner groove 8, inside the fixing groove 7, and inside the rotating groove 6.

[0035] Reference Figure 3 Figure 6The adjustment assembly includes a fixing bar 16, which provides a rigid support base for the lamp body 21, bears the working load of the adjustment mechanism, and ensures stable illumination angle without deviation. The bottom end of the fixing bar 16 is fixedly connected to the top of the outer shell 1. A rotating column 13 is rotatably connected to the top of the fixing bar 16 for horizontal rotation adjustment of the lamp body 21, expanding and contracting the illumination coverage. A rotating column 25 is rotatably connected to the top of the fixing bar 16 for vertical pitch adjustment of the lamp body 21, precisely controlling the beam projection angle. A connecting column 10 is fixedly connected inside the rotating column 25 for transmitting support force and integrating an angle locking mechanism. The lamp body 21 is fixedly connected to the outer wall of the connecting column 10 to provide illumination. A sliding groove 11 is provided inside the connecting column 10 to provide a linear motion track for the push block 14 and constrain the pitch adjustment stroke. A connecting column 22 is rotatably connected inside the rotating column 13 to convert rotational motion into linear motion. Linear thrust enables fine-tuning of the horizontal angle. One end of connecting post 2 12 is fixedly connected to push block 14, and the outer wall of push block 14 slides in sliding groove 11. A pull rod 17 is slidably connected inside connecting post 1 10 to transmit the unlocking operation force and remove the fixation of the locking block 22. One end of pull rod 17 is fixedly connected to locking block 22 to embed into the scale groove of fixing strip 16 and provide anti-torque locking force. A limit block 19 is fixedly connected to the top of locking block 22 to limit the displacement range of locking block 22 and prevent overload damage to the mechanism. A spring 2 18 is sleeved on the outer wall of pull rod 17 to provide constant preload force and maintain the angle locking state. One end of spring 2 18 is fixedly connected to connecting post 1 10, and the other end of spring 2 18 is fixedly connected to the outer wall of locking block 22. An inner groove 20 is opened inside connecting post 1 10 to guide the movement trajectory of locking block 22 and ensure that the locking position accurately corresponds to the angle scale. The outer wall of locking block 22 slides inside inner groove 20.

[0036] Working principle: First, press down on the push button 2. The push button 2 compresses the spring 3, which drives the connecting rod 4. The connecting rod 4 drives the fixing block 5 to slide inward. When the fixing block 5 reaches the designated position, rotate the push button 2. The fixing block 5 rotates in the rotating groove 6. When it rotates to the designated position, release the push button 2. Under the rebound action of the spring 3, the fixing block 5 is driven into the fixing groove 7, thereby fixing the locking block 9 to the outer shell 1. Press down on the push button 2 and rotate the push button 2 to release the fixing between the outer shell 1 and the locking block 9, thereby removing the locking block 9. Under the action of the spring 3, the fixing block 5 retracts into the inner groove 8, achieving the effect of quick disassembly.

[0037] Pulling the lever 17 causes the locking block 22 to move and compress the second spring 18, thereby releasing the locking block 22 from fixing the push block 14. The connecting column 10 is pressed down, and the push block 14 slides in the sliding groove 11. The connecting column 10 rotates around the second rotating column 15, and the second connecting column 12 rotates around the first rotating column 13, thereby retracting the connecting column 10 into the outer shell 1. Pulling the connecting column 10 upward causes the locking block 22 to have an inherent inclined surface structure. When the push block 14 slides, the locking block 22 is compressed. When the push block 14 reaches the designated position, the second spring 18 pushes the locking block 22 into the push block 14, thereby fixing the locking block 22 and achieving the effect of retracting the connecting column 10.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
