[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] See also Figure 1-5The utility model provides a technical solution: a power cord plug with overheat protection, comprising a fixed shell 1 and a fixed shell 2, a buzzer 3 is installed in the middle of the fixed shell 1, a sealing gasket 10 is arranged on the top of the fixed shell 1, and a groove 14 is opened at the bottom of the fixed shell 2, the sealing gasket 10 is installed in the inside of the groove 14, and the fixed shell 1 and the fixed shell 2 are connected by bolts, and a power line 4 is clamped on one side of the fixed shell 1 and the fixed shell 2, and a limit rod 15 is fixedly installed on the left and right sides of the inside of the fixed shell 2, and the outside of the two limit rods 15 is slidably connected with a mounting shell 6, a plug 5 is installed on one side of the mounting shell 6, and a positioning component 7 is fixedly installed in the middle of one side of the mounting shell 6, and a temperature sensor 11 and a relay 12 are respectively installed inside the mounting shell 6, and the power line 4 is connected to the relay 12.
[0026] The mounting shell 6 and the plug-in piece 5 can be mounted through the fixing shell 1 and the fixing shell 2. When working, the mounting shell 6 is pushed to slide along the two limit rods 15, so that the plug-in piece 5 leaks out, and the plug-in piece 5 is inserted into the jack of the power socket, and is connected with the relay 12 through the power cord 4. At the same time, the temperature sensor 11 can monitor the temperature inside the mounting shell 6 in real time, and the temperature control data of the temperature sensor 11 is transmitted to the relay 12, so that when the temperature inside the mounting shell 6 is too high, the relay 12 disconnects the circuit between the plug-in piece 5 and the power socket, thereby preventing the temperature of the plug-in piece 5 from being too high and causing the fixing shell 1 and the fixing shell 2 2 to be deformed by heat, and the plug-in piece 5 is disconnected from the power socket circuit, and the relay 12 triggers the buzzer 3 to make a sound, thereby reminding the user to pay attention, thereby avoiding causing electricity safety accidents.
[0027] See also Figure 3 , Figure 4 A slide groove 8 is opened inside the fixed shell 2, and a slider 9 is fixedly installed at the lower end of the mounting shell 6. The slider 9 is slidably installed inside the slide groove 8. The insert 5 is slidably installed inside the fixed shell 1 and the fixed shell 2, and a slot 13 is opened on one side of the fixed shell 1 and the fixed shell 2, and the slot 13 is kept level with the positioning component 7.
[0028] The plug-in piece 5 can be retracted through the installation shell 6. Since the slider 9 is fixedly installed at the bottom of the installation shell 6 and the slider 9 is slidably installed in the inside of the slide groove 8, pushing the slider 9 can respectively drive the positioning component 7, the installation shell 6 and the plug-in piece 5 to slide along the two limit rods 15 toward the fixed shell 1 and the fixed shell 2, so that the plug-in piece 5 leaks out. Since the card slot 13 and the positioning component 7 are kept horizontal, the positioning component 7 passes through the card slot 13 at this time to fix the plug-in piece 5, thereby facilitating the retraction of the plug-in piece 5 and saving the space of the plug.
[0029] See also Figure 2 , Figure 4The power line 4 is connected to the slide slot 8 and the plug 5 respectively, and the relay 12 is connected to the buzzer 3 through a wire. The power line 4 inside the fixed shell 1 and the fixed shell 2 is bent, and a rubber insulating layer is provided inside the mounting shell 6.
[0030] The power cord 4 is connected to the slide slot 8 and the plug 5, and the slide slot 8 and the buzzer 3 are connected by a wire. The temperature sensor 11 monitors the temperature inside the installation shell 6 in real time, and the temperature sensor 11 transmits the temperature control data to the relay 12. When the temperature inside the installation shell 6 is too high, the relay 12 disconnects the circuit between the plug 5 and the power socket, thereby preventing the plug 5 from being overheated and causing the fixed shell 1 and the fixed shell 2 2 to be deformed by heat, and the plug 5 is disconnected from the power socket circuit. At this time, the relay 12 triggers the buzzer 3 to make a sound, thereby reminding the user to pay attention, and a rubber insulating layer is provided inside the installation shell 6, so that the temperature sensor 11 and the relay 12 inside the installation shell 6 will not leak electricity, thereby avoiding electrical safety accidents.
[0031] See also Figure 4 , Figure 5 The positioning assembly 7 includes a latch 701, which is fixedly installed in the middle of one side of the mounting shell 6, and the latch 701 and the card slot 13 are kept horizontal. Two mounting grooves 702 are opened inside the latch 701, and a mounting rod 703 is installed on the top of the mounting groove 702. The two mounting rods 703 are hinged with a card block 704 on the outside, and one side of the two card blocks 704 is fixedly connected with a spring 705. The two card blocks 704 remain symmetrical, and one end of the two springs 705 is fixedly connected to one side of the two card blocks 704, and the other end of the two springs 705 is fixedly connected to the inner side of the two mounting grooves 702.
[0032] The plug-in piece 5 can be fixed by the latch 701 in the positioning assembly 7. Since the latch 701 and the slot 13 are kept horizontal, the mounting shell 6 drives the plug-in piece 5 and the latch 701. When sliding along the two limit rods 15, the latch 701 penetrates the slot 13 and is hinged to the outside of the mounting rod 703 through two clamping blocks 704. One side of the two clamping blocks 704 is fixedly connected with a spring 705. As a result, when the latch 701 penetrates the mounting slot 702, the two clamping blocks 704 and the spring 705 are compressed to enter the interior of the mounting slot 702. After the clamping block 704 completely penetrates the slot 13, the two clamping blocks 704 are pushed to reset under the elastic action of the spring 705, thereby fixing the plug-in piece 5 and the mounting shell 6.
[0033] During operation, the mounting shell 6 and the plug-in piece 5 can be installed through the fixed shell 1 and the fixed shell 2. During operation, the mounting shell 6 is pushed to slide along the two limit rods 15, so that the plug-in piece 5 leaks out, and the plug-in piece 5 is inserted into the jack of the power socket, and is connected with the relay 12 through the power cord 4. At the same time, the temperature sensor 11 can monitor the temperature inside the mounting shell 6 in real time, and the temperature control data of the temperature sensor 11 is transmitted to the relay 12, so that when the temperature inside the mounting shell 6 is too high, the relay 12 disconnects the circuit between the plug-in piece 5 and the power socket, thereby preventing the temperature of the plug-in piece 5 from being too high and causing the fixed shell 1 and the fixed shell 2 to be deformed by heat, and the plug-in piece 5 is disconnected from the power socket circuit, and the relay 12 triggers the buzzer 3 to make a sound, thereby reminding the user to pay attention, thereby avoiding causing electricity safety accidents.
[0034] The plug-in piece 5 can be retracted through the installation shell 6. Since the slider 9 is fixedly installed at the bottom of the installation shell 6 and the slider 9 is slidably installed in the inside of the slide groove 8, pushing the slider 9 can respectively drive the positioning component 7, the installation shell 6 and the plug-in piece 5 to slide along the two limit rods 15 toward the fixed shell 1 and the fixed shell 2, so that the plug-in piece 5 leaks out. Since the card slot 13 and the positioning component 7 are kept horizontal, the positioning component 7 passes through the card slot 13 at this time to fix the plug-in piece 5, thereby facilitating the retraction of the plug-in piece 5 and saving the space of the plug.
[0035] The power cord 4 is connected to the slide slot 8 and the plug 5, and the slide slot 8 and the buzzer 3 are connected by a wire. The temperature sensor 11 monitors the temperature inside the installation shell 6 in real time, and the temperature sensor 11 transmits the temperature control data to the relay 12. When the temperature inside the installation shell 6 is too high, the relay 12 disconnects the circuit between the plug 5 and the power socket, thereby preventing the plug 5 from being overheated and causing the fixed shell 1 and the fixed shell 2 2 to be deformed by heat, and the plug 5 is disconnected from the power socket circuit. At this time, the relay 12 triggers the buzzer 3 to make a sound, thereby reminding the user to pay attention, and a rubber insulating layer is provided inside the installation shell 6, so that the temperature sensor 11 and the relay 12 inside the installation shell 6 will not leak electricity, thereby avoiding electrical safety accidents.
[0036] The plug-in piece 5 can be fixed by the latch 701 in the positioning assembly 7. Since the latch 701 and the slot 13 are kept horizontal, the mounting shell 6 drives the plug-in piece 5 and the latch 701. When sliding along the two limit rods 15, the latch 701 penetrates the slot 13 and is hinged to the outside of the mounting rod 703 through two clamping blocks 704. One side of the two clamping blocks 704 is fixedly connected with a spring 705. As a result, when the latch 701 penetrates the mounting slot 702, the two clamping blocks 704 and the spring 705 are compressed to enter the interior of the mounting slot 702. After the clamping block 704 completely penetrates the slot 13, the two clamping blocks 704 are pushed to reset under the elastic action of the spring 705, thereby fixing the plug-in piece 5 and the mounting shell 6.
[0037] In summary, the temperature sensor 11 of the device monitors the temperature inside the mounting shell 6 in real time, and the temperature sensor 11 transmits the temperature control data to the relay 12. When the temperature inside the mounting shell 6 is too high, the relay 12 disconnects the circuit between the plug 5 and the power socket, thereby preventing the plug 5 from being too hot and causing the fixed shell 1 and the fixed shell 2 2 to be deformed by heat. The plug 5 is disconnected from the power socket circuit, and the relay 12 triggers the buzzer 3 to make a sound, thereby reminding the user to pay attention. In addition, a rubber insulating layer is provided inside the mounting shell 6, so that the temperature sensor 11 and the relay 12 inside the mounting shell 6 will not leak electricity, thereby avoiding electrical safety accidents.
