Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a connecting device for connecting three-proof lamps to each other. Background Art

[0002] Three-proof lamps, namely waterproof, dustproof and anticorrosive lamps, are widely used in places such as railways, electric power, metallurgy, petrochemical industry, various factory areas, stations, large facilities, and stadiums to meet the needs of high-brightness floodlighting. In high-risk environments such as the chemical industry, mines, docks, and ships, the use of three-proof lamps can ensure the stable operation of lighting equipment in harsh environments, thereby protecting the lives and property safety of personnel.

[0003] Currently, when it is necessary to provide lighting for a large area of space, the lighting range of a single three-proof lamp may not meet the requirements. At this time, it is necessary to splice two or more three-proof lamps to expand the lighting range and ensure that the entire area can be evenly and sufficiently illuminated. The existing splicing of two three-proof lamps usually uses screws for connection. Screw connection requires tools and equipment such as screwdrivers and wrenches. Therefore, the splicing is dependent on specific tools. In case of emergency or in the absence of suitable tools, it may lead to inability to quickly install or disassemble, affecting the progress of work, and thus affecting the normal use of the lighting system. Screw connection requires installing screws one by one, resulting in a relatively long process for splicing and disassembling, reducing work efficiency.

[0004] Therefore, it is necessary to provide a new connecting device for connecting three-proof lamps to each other to solve the above technical problems. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a connecting device for connecting three-proof lamps to each other.

[0006] The connecting device for connecting three-proof lamps to each other provided by the utility model includes two bases, and the two bases are connected by a connecting device;

[0007] The connecting device includes two placement frames and two fixing seats. The two placement frames are respectively fixedly connected to one side of the two bases. One side of each of the two placement frames is provided with a clamping block, and a clamping groove is formed in the side wall of each of the two placement frames. The two fixing seats are respectively fixedly connected to the inner walls of the two placement frames, and a fixing column is fixedly connected to one end of each of the two fixing seats. One end of the fixing column is fixedly connected with an elastic member, and a limiting component is fixedly connected to the end of the elastic member away from the fixing column.

[0008] Preferably, the limiting component includes a fixing block, the fixing block is fixedly connected to one end of the elastic member, a movable rod is fixedly connected to the end of the fixing block away from the elastic member, and a movable block is fixedly connected to the end of the movable rod away from the fixing block.

[0009] Preferably, the elastic member is a tension spring, one end of the tension spring is fixedly connected to one end of the fixed column, and the end of the tension spring away from the fixed column is fixedly connected to one end of the fixed block.

[0010] Preferably, the clamping block is movably connected to the inner wall of the clamping groove.

[0011] Preferably, a lamp body is fixedly connected to the base.

[0012] Preferably, a wire passing hole is provided on the bottom surface of the base.

[0013] Compared with the related art, a lamp connection device for a three-proof lamp provided by the present invention has the following beneficial effects:

[0014] When implementing a lamp connection device for a three-proof lamp provided by the present invention, when it is necessary to splice two three-proof lamps, first place the two placement frames on the same horizontal line, and then insert the two clamping blocks into the corresponding clamping grooves respectively. During the process of the two clamping blocks entering the clamping grooves respectively, under the extrusion of the placement frame, the movable block rotates by a certain angle, the movable block drives the movable rod to move, the movable rod drives the fixed block, and the fixed block stretches the tension spring. When the clamping blocks are all inserted into the clamping grooves, the movable block loses the restriction of the placement frame, and under the action of the tension spring, the fixed block drives the movable rod and the movable block to return to the initial position, and the movable block restricts the placement frame. Therefore, the splicing of the two three-proof lamps is completed through the splicing of the placement frames. Through the above mechanism for splicing the three-proof lamps, the problem that in an emergency or without suitable tools, it may lead to inability to install or disassemble quickly, affecting the work progress is solved, and the problem that screw connection requires installing screws one by one, resulting in a relatively long splicing and disassembly process and reducing work efficiency is solved.

[0023] In the specific implementation process, as Figures 1 to 5As shown in the figure, two bases 1 are connected by a connecting device. The connecting device includes two placement frames 2 and two fixed seats 3. The two placement frames 2 are respectively fixedly connected to one side of the two bases 1. A clamping block 9 is provided on one side of each of the two placement frames 2, and a clamping groove 10 is formed on the side wall of each of the two placement frames 2. The two fixed seats 3 are respectively fixedly connected to the inner walls of the two placement frames 2, and a fixed column 4 is fixedly connected to one end of each of the two fixed seats 3. An elastic member is fixedly connected to one end of the fixed column 4. The end of the elastic member away from the fixed column 4 is fixedly connected to a limiting component. The limiting component includes a fixed block 6. The fixed block 6 is fixedly connected to one end of the elastic member. A movable rod 7 is fixedly connected to the end of the fixed block 6 away from the elastic member. A movable block 8 is fixedly connected to the end of the movable rod 7 away from the fixed block 6. The elastic member is a tension spring 5. One end of the tension spring 5 is fixedly connected to one end of the fixed column 4, and the end of the tension spring 5 away from the fixed column 4 is fixedly connected to one end of the fixed block 6. The clamping block 9 is movably connected to the inner wall of the clamping groove 10. A lamp body 11 is fixedly connected to the base 1, and a wire passing hole is provided on the bottom surface of the base 1. When it is necessary to splice two explosion-proof lamps, first place the two placement frames 2 on the same horizontal line, and then insert the two clamping blocks 9 into the corresponding clamping grooves 10 respectively. During the process of the two clamping blocks 9 entering the clamping grooves 10 respectively, under the extrusion of the placement frame 2, the movable block 8 rotates by a certain angle. The movable block 8 drives the movable rod 7 to move, the movable rod 7 drives the fixed block 6, and the fixed block 6 stretches the tension spring 5. When the clamping block 9 is completely inserted into the clamping groove 10, the movable block 8 loses the restriction of the placement frame 2. Under the action of the tension spring 5, the fixed block 6 drives the movable rod 7 and the movable block 8 to return to the initial position, and the movable block 8 restricts the placement frame 2. Therefore, the splicing of the two explosion-proof lamps is completed through the splicing of the placement frames 2.

[0024] The working principle provided by the present utility model is as follows: When it is necessary to splice two explosion-proof lamps, first place the two placement frames 2 on the same horizontal line, and then insert the two clamping blocks 9 into the corresponding clamping grooves 10 respectively. During the process of the two clamping blocks 9 entering the clamping grooves 10 respectively, under the extrusion of the placement frame 2, the movable block 8 rotates by a certain angle. The movable block 8 drives the movable rod 7 to move, the movable rod 7 drives the fixed block 6, and the fixed block 6 stretches the tension spring 5. When the clamping block 9 is completely inserted into the clamping groove 10, the movable block 8 loses the restriction of the placement frame 2. Under the action of the tension spring 5, the fixed block 6 drives the movable rod 7 and the movable block 8 to return to the initial position, and the movable block 8 restricts the placement frame 2. Therefore, the splicing of the two explosion-proof lamps is completed through the splicing of the placement frames 2.
