Technical Field

[0001] This utility model relates to the field of lighting structure technology, and in particular to a safety lighting fixture with anti-electric shock function. Background Technology

[0002] With the widespread use of lighting equipment, lamps have become an indispensable infrastructure in homes, offices and industrial sites. Safety lamps with anti-electric shock functions have emerged to improve electrical safety.

[0003] This application (CN222164701U) discloses an anti-electric shock lamp holder for LED bulbs, belonging to the field of LED lamp holder design technology. It includes: a base forming a mounting cavity; a longitudinally moving member positioned on the upper part of the mounting cavity and moving longitudinally relative to the mounting cavity, the longitudinally moving member forming an internal thread, and a downward-facing first abutment portion formed at its lower end; and a transversely moving member with a contact point and a second abutment portion formed on its upper surface.

[0004] In the process of realizing this application, the inventors discovered the following problems with the prior art: Although the prior art has taken measures to prevent accidental contact in its design, it still relies on the operator's accurate installation. Its complicated operation steps and high requirements for installation accuracy, as well as the need for a long time to align and rotate the threaded connection when replacing the bulb, increase the difficulty of use. At the same time, it also makes the disassembly and installation process more cumbersome and not convenient for quick operation. Utility Model Content

[0005] The main purpose of this utility model is to propose a safety lamp with anti-electric shock function, which aims to solve the problems existing in the prior art.

[0006] To solve the above problems, this utility model proposes a safety lamp with anti-electric shock function, including: a protective device and a protective bracket. The protective bracket includes a fixed base, a mounting shell is provided at the top of the fixed base, a connecting device is fixedly provided on the top surface of the inner wall of the mounting shell, the protective device is connected to the connecting device, and a lamp body is fixedly provided at the lower end of the protective device.

[0007] The connecting device includes an insulating shell, a connecting sleeve fixedly disposed on the inner wall of the insulating shell, a plurality of limiting grooves surrounding the inner wall of the connecting sleeve, and conductive plates disposed in at least two sliding grooves on the bottom surface of the inner wall of the insulating shell, and conductive springs fixedly disposed on the bottom surface of at least two of the conductive plates. The above structure achieves a reliable connection with the power supply through the connecting device, and effectively covers the conductive components through the protective device, thereby improving the safety performance during use.

[0008] In one embodiment, the protection device includes an insulating cover, a top cover fixedly mounted on the top surface of the insulating cover, a conductive post fixedly mounted at the center point of the bottom surface of the inner wall of the insulating cover, a plurality of connecting springs mounted at the top of the conductive post, a neutral wire pin fixedly mounted at the top of each of the plurality of connecting springs, and conductive plates fixedly mounted on both sides of the upper position of the inner wall of the insulating cover, with live wire pins fixedly mounted on both sides of the conductive plates. The live wire pins pass through openings at corresponding positions on the top cover and extend outward to the outside of the protection device for connection with an external power source.

[0009] In one embodiment, the outer surface of the insulating cover is provided with three limiting holes at angular intervals along the circumferential direction. The three neutral wire pins are respectively inserted into the corresponding limiting holes and extend outward for electrical connection with the external neutral wire terminal.

[0010] In one embodiment, the lamp body is an integral structure, including a mounting compartment, multiple heat dissipation fins connected to the bottom of the mounting compartment, and a light bulb fixedly disposed below the heat dissipation fins. The mounting compartment is used to accommodate the power supply components and support the light bulb.

[0011] In one embodiment, the fins are arranged in a multi-layered annular structure, with the overall structure gradually thickening from top to bottom to increase the heat dissipation area and improve air convection efficiency.

[0012] Beneficial effects:

[0013] By combining the connecting device with the protection device, the risk of electric shock and misoperation problems caused by traditional threaded connections are avoided. The simplified operation process improves the user experience. With the limiting groove and the rotating plug-in structure, users can complete the connection with just a simple rotation, avoiding the cumbersome steps of traditional threaded connections, significantly reducing the difficulty of installation, and improving overall efficiency and safety.

[0014] The live wire pins need to be precisely aligned with the conductive plate through a rotating motion before power is supplied. This prevents the risk of accidental contact with the electrodes during installation, avoids possible electric shock accidents, and ensures operational safety.

[0015] The lamp body and connecting device can be quickly disassembled and assembled, saving users time when replacing or maintaining the lamp, improving operational efficiency, increasing convenience, and adapting to more different usage environments, especially in situations where frequent bulb replacement is required.

[0027] 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.

[0028] To achieve the above-mentioned utility model objectives, such as Figure 1-8As shown, this utility model provides a safety lamp with anti-electric shock function, including: a protection device 2 and a protective bracket 4. The protective bracket 4 includes a fixed base 401. The top of the fixed base 401 is provided with a mounting shell 402. The top surface of the inner wall of the mounting shell 402 is fixedly provided with a connecting device 1. The protection device 2 is connected to the connecting device 1. The lower end of the protection device 2 is fixedly provided with a lamp body 3.

[0029] The connecting device 1 includes an insulating shell 101, a connecting sleeve 102 fixedly disposed on the inner wall of the insulating shell 101, a plurality of limiting grooves 103 surrounding the inner wall of the connecting sleeve 102, and conductive plates 104 disposed in at least two sliding grooves on the bottom surface of the inner wall of the insulating shell 101, and conductive spring pieces 105 fixedly disposed on the bottom surface of at least two conductive plates 104. The above structure achieves a reliable connection with the power supply through the connecting device 1, and effectively covers the conductive components through the protection device 2, thereby improving the safety performance during use.

[0030] Specifically, the insulating shell 101 is made of PA66 material, which has excellent insulation performance and thermal stability, effectively improving the safety and reliability of the lamp. The connecting sleeve 102 is made of copper material, which has good conductivity and is electrically connected to the neutral wire end through its external structure to achieve safe and stable electrical conduction. The inner wall of the connecting sleeve 102 is provided with three limiting grooves 103 at 120-degree intervals along the circumference. Each limiting groove 103 has an L-shaped structure and a positioning hole at the corner near its lower end, which is used to insert and limit the neutral wire plug 206 to ensure the stability and reliability of the neutral wire connection. The bottom surface of the inner wall of the insulating shell 101 has multiple teardrop-shaped guide slots. The slots are wider at the entrance to facilitate insertion and gradually narrow inward to improve the insertion accuracy and self-locking. A concave hole is provided at the narrow end of the bottom surface of the inner wall of the teardrop-shaped groove. A conductive plate 104 is installed in the concave hole, and its lower end is connected to a conductive spring 105 and electrically connected to the live wire for current on / off control. In addition, a sliding groove structure is provided around the lower part of the teardrop-shaped groove. A circular copper plate is provided at the top of the live wire pin 205. The copper plate can slide and engage in the sliding groove, which serves as a limit and anti-misalignment function. The fixed base 401 is H-shaped and has connecting rods fixedly provided on both sides. The top of the connecting rods is rotatably connected to both sides of the mounting shell 402, which facilitates the adjustment of the light direction during use. The mounting shell 402 is connected to the connecting device 1 fixedly provided at the top of the inner wall through the inner wall wiring and the control panel. The electrical wiring and control panel involved in this utility model are existing mature technologies and have been widely used in the industry, so they will not be described in detail. The innovation of this utility model lies in the improvement and optimization of its structural design and working principle.

[0031] 2. In order to achieve the above-mentioned utility model objectives, such as... Figure 1-7As shown, this utility model provides a safety lamp with anti-electric shock function. The protection device 2 includes an insulating cover 201. The insulating cover 201 has a top cover 203 fixedly installed on its top surface. A conductive post 207 is fixedly installed at the center point of the bottom surface of the inner wall of the insulating cover 201. Multiple connecting springs 202 are provided at the top of the conductive post 207. A neutral wire plug 206 is fixedly installed at the top of each of the multiple connecting springs 202. Conductive plates 204 are fixedly installed on both sides of the upper position of the inner wall of the insulating cover 201. A live wire plug 205 is fixedly installed on both sides of the conductive plate 204. The live wire plug 205 passes through the opening at the corresponding position on the top cover 203 and extends outward to the protection device. The outer surface of the device 2 is used to connect to an external power source. The outer surface of the insulating cover 201 is provided with three limiting holes at 120-degree angles along the circumference. The three neutral wire pins 206 are respectively inserted into the corresponding limiting holes and extend outward for electrical connection with the external neutral wire terminal. The lamp body 3 is an integral structure, including a mounting compartment 301, multiple heat dissipation fins 302 connected to the bottom of the mounting compartment 301, and a bulb 303 fixedly installed below the heat dissipation fins 302. The mounting compartment 301 is used to accommodate the power supply components and support the bulb 303. The fins 302 are arranged in a multi-layer ring structure, and the overall structure gradually thickens from top to bottom to increase the heat dissipation area and improve the air convection efficiency.

[0032] Specifically, the neutral wire plug 206 is located in three limiting slots spaced 120 degrees apart along the circumference of the insulating cover 201, and achieves elastic contact with the conductive post 207 through the connecting spring 202. During the installation of the lamp, the neutral wire plug 206 is first inserted into the L-shaped sliding groove on the inner wall of the connecting sleeve 102, and slides along its path to form a reliable electrical connection with the external neutral wire. At this time, the lamp body 3 has not yet been fully rotated and positioned, and the live wire is not connected, so the circuit is in an open state, effectively preventing accidental contact with live wires and ensuring the personal safety of the operator. Subsequently, the user rotates the lamp body 3 to make... The live wire pin 205 slides along the teardrop-shaped slot on the bottom surface of the insulating shell 101. During rotation, the neutral wire pin 206 simultaneously enters the limiting hole at the bottom of the L-shaped slot for further limiting and fixing. Simultaneously, the live wire pin 205 rotates within the teardrop-shaped slot. When the circular copper piece at its top slides into the slot structure for limiting engagement, the rounded top makes electrical contact with the conductive plate 104 located at the narrow end of the teardrop slot. The conductive spring 105 at the bottom of the conductive plate 104 connects to the external live wire power supply, thus enabling the live wire to be energized and forming a complete electrical circuit. This is achieved by first connecting the neutral wire... The sequence of actions for connecting the live wire after the lamp body 3 is rotated and positioned ensures that the live wire cannot be energized before the lamp body 3 is fully rotated and positioned, significantly reducing the risk of electric shock. Furthermore, all conductive components involving the live and neutral wires (such as the live wire pin 205, neutral wire pin 206, conductive plate 104, conductive spring 105, etc.) are enclosed within the internal structure of the insulating cover 201 and the insulating shell 101. Through installation and cooperation with the connecting device 1, complete coverage of high-voltage parts is achieved, preventing exposed conductive contacts and significantly improving safety against electric shock. The live wire pin 205 is located on the top cover 203... The sealed hole structure leads out, and the electrical connection is only formed after the lamp body 3 is rotated and aligned and inserted into the predetermined position. This structurally prevents non-insertion operation when the lamp is powered on. In terms of heat dissipation, the mounting chamber 301 is integrally formed with multiple heat dissipation fins 302. The fins 302 extend downward in a multi-layer ring structure and are thermally coupled to the periphery of the bulb 303. The overall structure thickens layer by layer from top to bottom, effectively expanding the heat dissipation area and optimizing the air convection path to achieve rapid heat conduction, uniform heat dissipation and temperature rise control, ensuring that the lamp has good thermal management performance and service life under continuous working conditions.

[0033] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
