In the daily operation and maintenance of electrical equipment, the prevention of electrical fires is of paramount importance. Electrical fire detectors are needed to detect dangerous signals such as abnormal temperature, electric arc, leakage, and overload in electrical systems. Through audible and visual alarms and data transmission, alarms are issued at the incipient stage of a fire to prevent the accident from escalating.

[0003] Problems with existing technology:

[0004] Existing electrical fire detectors typically use direct connection via external power or signal lines. This connection method results in cumbersome and time-consuming disassembly and installation processes when the equipment needs maintenance or replacement, which not only reduces work efficiency but also increases the workload of operators. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary detection device for electrical fire prevention inspection, which can effectively avoid the trouble of disassembly and installation caused by directly connecting external power lines or signal lines to the main body of the electrical fire detector. This facilitates the maintenance or replacement of the main body of the electrical fire detector, improves the efficiency of disassembling or installing the main body of the electrical fire detector, and reduces labor intensity.

[0006] The specific technical solution adopted by this utility model is as follows:

[0008] The top of the mounting base is provided with multiple first electrical interfaces, and the bottom of the mounting base is provided with multiple second electrical interfaces for electrical connection between an external power supply or an external detection probe and the mounting base.

[0009] The mounting groove is provided with a top plate corresponding to the conductive post inside. The top plate has multiple through holes on one side, the same number as the conductive post, and the conductive post and the through hole are aligned one by one. The four corners of the top plate are provided with telescopic rods fixed to the inside of the mounting groove, and the outer wall of the telescopic rod is fitted with a second spring.

[0010] An elastic rubber sealing sheet is provided on the inner side of the through hole, and an expansion port is provided through the center of the elastic rubber sealing sheet.

[0011] The card slot has a retention groove on its inner side, and a second insertion groove is provided on the inner side of the retention groove.

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figures 1-5 As shown, an auxiliary detection device for electrical fire prevention includes a mounting base 1. A mounting groove 2 is provided on one side of the mounting base 1. A detachable electrical fire detector body 6 is installed inside the mounting groove 2. Limiting plates 3 are provided on both sides of the mounting groove 2 and on both sides of the electrical fire detector body 6. Multiple first insertion slots 4 are vertically and equidistantly provided on one side of each limiting plate 3. A locking block 5 is slidably disposed inside each first insertion slot 4. An inclined sliding surface is provided on one side of each locking block 5, which allows the locking block 5 to retract into the first insertion slot 4 when the electrical fire detector body 6 slides in contact with the inclined sliding surface. A... A first spring is fixed to the inside of the first insertion slot 4. The main body 6 of the electrical fire detector has slots 7 on both sides that cooperate with the locking block 5. A plurality of conductive posts 10 are provided on one side of the mounting slot 2. A conductive groove is provided on one side of the main body 6 of the electrical fire detector that is electrically connected to the conductive posts 10, and one end of the conductive post 10 is inserted into the conductive groove for electrical connection between the main body 6 of the electrical fire detector and the mounting base 1. A plurality of first electrical interfaces 8 are provided on the top of the mounting base 1, and a plurality of second electrical interfaces 9 are provided on the bottom of the mounting base 1 for electrical connection between the external power supply or the external detection probe and the mounting base 1.

[0025] According to the above structure, when fixing the main body 6 of the electrical fire detector, the main body 6 is pushed to move, and the two limiting plates 3 limit it, so that the main body 6 moves into the mounting groove 2. The locking block 5 is aligned with the slot 7, and the elastic force of the first spring makes the locking block 5 insert into the slot 7, thereby fixing the main body 6 of the electrical fire detector. At the same time, the conductive post 10 is inserted into the conductive groove, so that the main body 6 of the electrical fire detector is electrically connected to the mounting base 1. This structure effectively avoids the trouble of disassembly and installation caused by directly connecting the external power line or signal line to the main body 6 of the electrical fire detector, and facilitates the maintenance or replacement of the main body 6 of the electrical fire detector, improving the efficiency of disassembly or installation of the main body 6 of the electrical fire detector and reducing labor intensity.

[0026] like Figures 2-3 As shown, a top plate 11 is provided inside the mounting groove 2 corresponding to the conductive post 10. A telescopic sealing cover 14 is provided at the edges of the four sides of the top plate 11, and the other end of the telescopic sealing cover 14 is fixed to the inside of the mounting groove 2. A plurality of through holes 13, the same number as the conductive post 10, are opened on one side of the top plate 11, and the conductive post 10 is aligned with the through hole 13 one by one. Telescopic rods fixed to the inside of the mounting groove 2 are provided on the outer walls of the four corners of the top plate 11. A second spring 12 is sleeved on the outer wall of the telescopic rod. An elastic rubber sealing sheet 15 is provided inside the through hole 13, and an expansion port is provided through the center of the elastic rubber sealing sheet 15. The expansion port can expand when the conductive post 10 is inserted without affecting the electrical connection.

[0027] According to the above structure, when the main body 6 of the electrical fire detector is installed, it will push the top plate 11 to compress the second spring 12, so that the conductive post 10 can pass through the through hole 13 and the elastic rubber sealing sheet 15 and be inserted into the conductive groove. With the reaction force of the second spring 12, the top plate 11 is pushed to hold the main body 6 of the electrical fire detector, which can effectively ensure the stability of the electrical connection. When the main body 6 of the electrical fire detector is disassembled, the second spring 12 pushes the top plate 11 to reset. The elastic rubber sealing sheet 15 can effectively prevent dust and moisture from entering the sealed cavity formed by the telescopic sealing cover 14 and the top plate 11, which can effectively protect the conductive post 10 when the main body 6 of the electrical fire detector is separated from the mounting base 1.

[0028] like Figures 4-6 As shown, a retention groove 16 is provided on the inner side of the slot 7, and a second insertion groove 17 is provided on the inner side of the retention groove 16. The other end of the second insertion groove 17 is bent at a 90-degree angle and communicates with the main body 6 of the electrical fire detector. An insertion rod 18 is provided inside the second insertion groove 17. One end of the insertion rod 18 is located in the retention groove 16 and is bent at a 90-degree angle, and its end is flush with the side wall of the main body 6 of the electrical fire detector. The other ends of the multiple insertion rods 18 extend to the outside of the second insertion groove 17 and are fixed with connecting rods 19. A handle 20 is fixed on the outer wall of the main body 6 of the electrical fire detector and on one side of the connecting rod 19.

[0029] According to the above structure, when disassembling the main body 6 of the electrical fire detector, hold the handle 20 with both hands and press the connecting rod 19 with your thumb. The connecting rod 19 drives the plug rod 18. One end of the plug rod 18 squeezes the locking block 5 and pushes the locking block 5 into the first plug groove 4, so that the locking block 5 is separated from the groove 7. Then the main body 6 of the electrical fire detector can be easily separated from the mounting base 1.

[0030] The working principle of this utility model is as follows: When fixing the main body 6 of the electrical fire detector, the main body 6 of the electrical fire detector is pushed to move, and the two limiting plates 3 limit it, so that the main body 6 of the electrical fire detector moves into the mounting groove 2. The locking block 5 is aligned with the locking groove 7. Through the elastic force of the first spring, the locking block 5 is inserted into the locking groove 7 to fix the main body 6 of the electrical fire detector. At the same time, the conductive post 10 is inserted into the conductive groove to make the main body 6 of the electrical fire detector electrically connected to the mounting base 1.

[0031] When the main body 6 of the electrical fire detector is installed, it will push the top plate 11 to compress the second spring 12, so that the conductive post 10 can pass through the through hole 13 and the elastic rubber sealing sheet 15 and be inserted into the conductive groove. With the reaction force of the second spring 12, the top plate 11 is pushed to hold the main body 6 of the electrical fire detector, which can effectively ensure the stability of the electrical connection.

[0032] When disassembling the main body 6 of the electrical fire detector, hold the handle 20 with both hands and press the connecting rod 19 with your thumb. The connecting rod 19 drives the plug rod 18, and one end of the plug rod 18 presses against the locking block 5, pushing the locking block 5 into the first plug groove 4, so that the locking block 5 separates from the groove 7. Then the main body 6 of the electrical fire detector can be easily separated from the mounting base 1. At this time, the second spring 12 pushes the top plate 11 to reset. The elastic rubber sealing sheet 15 can effectively prevent dust and moisture from entering the sealed cavity formed by the telescopic sealing cover 14 and the top plate 11, and can effectively protect the conductive column 10 when the main body 6 of the electrical fire detector is separated from the mounting base 1.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
