It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a relay structure, including a main body mechanism 1, and a quick-release mechanism 2 is movably inserted into the inner surface wall of the main body mechanism 1;

[0026] The main mechanism 1 includes a shell 101, an electromagnetic device 102 is fixedly installed on the bottom of the inner wall of the shell 101, an input end of the electromagnetic device 102 is fixedly connected to a plug 103, and the outer wall of the plug 103 is movably inserted into the inside of the shell 101, an output end of the electromagnetic device 102 is fixedly connected to a plug 2 104, and the outer wall of the plug 2 104 is movably inserted into the inside of the shell 101, a spring 105 is fixedly installed on the bottom of the inner wall of the shell 101, a moving plate 106 is fixedly installed on the top of the spring 105, a group of rotating shafts 107 are fixedly installed on the outer wall of the moving plate 106, a group of brackets 108 are movably sleeved on the outer wall of the group of rotating shafts 107, and the bottoms of the group of brackets 108 are fixedly connected to the bottom of the inner wall of the shell 101, and a moving contact 109 is fixedly installed on the top of the moving plate 106 A group of fixing holes 110 are provided on the outer wall of the shell 101, and the output end of the moving contact 109 is fixedly connected to a wire 111, and the output end of the wire 111 is fixedly connected to a plug three 112, and the outer wall of the plug three 112 is movably inserted into the interior of the shell 101, and the top of the plug three 112 contacts with a static contact one 113, and the outer wall of the static contact one 113 is movably inserted into the interior of the shell 101, and a mounting rod 114 is fixedly installed on one side of the inner wall of the shell 101, and a push plate 115 is movably sleeved on the outer wall of the mounting rod 114, and the bottom of the push plate 115 contacts with a metal sheet 116, and one side of the outer wall of the metal sheet 116 is fixedly connected to one side of the inner wall of the shell 101, and the bottom of the push plate 115 contacts with a static contact two 117, and the outer wall of the static contact two 117 is movably inserted into the interior of the shell 101.

[0027] The effect achieved by the entire embodiment 1 is that after the operator provides power to the electromagnetic device 102, the electromagnetic device 102 will generate a magnetic field, drive the upper moving plate 106 to pull the spring 105 down, and make the moving contact 109 start to descend and contact the static contact 2 117, so that the circuit is connected. When the temperature inside the relay is too high, the metal sheet 116 begins to expand due to the heat, and one end of the push plate 115 is pushed upward to rotate it. The push plate 115 and the mounting rod 114 are combined into a laborious lever, which can amplify the thrust of the metal sheet 116. The other end of 115 is driven to squeeze the second static contact 117 downward, causing it to bend and separate from the moving contact 109, and the circuit is disconnected to prevent high temperature from damaging the internal electronic components. This not only extends the service life of the relay, but also improves the stability and reliability of the system. Timely circuit cutting can also prevent the relay from causing a fire. The internal temperature of the relay will continue to drop because the circuit is cut off. At this time, the metal sheet 116 begins to shrink. The second static contact 117 is made of metal material and has a certain elasticity. The second static contact 117 will return to its original position when there is no external force.

[0028] Embodiment 2, as Figure 2-Figure 4As shown, the quick release mechanism 2 includes a top cover 201, and the outer wall of the top cover 201 is provided with two grooves 202, and a group of springs 203 are fixedly installed on one side of the inner walls of the two grooves 202, and a clamping block 204 is fixedly installed between the outer walls of the two groups of springs 203, and the inner walls of the two grooves 202 are movably inserted with the outer walls of the clamping block 204, the inner wall of the outer shell 101 is movably inserted with the outer wall of the top cover 201, and the inner walls of the two fixing holes 110 are movably inserted with the outer walls of the clamping block 204.

[0029] The effect achieved by the entire embodiment 2 is that the operator only needs to press the two blocks 204 to pull them out from the two fixing holes 110 and squeeze the two sets of springs 203 to retract into the two grooves 202, and then the top cover 201 can be removed. This structure can realize the rapid disassembly and installation of the relay, thereby saving maintenance time and improving work efficiency.

[0030] Working principle: When the relay is in use, the operator first provides power to the electromagnetic device 102 through the plug 103 and the plug 2 104. When the electromagnetic device 102 is connected to the power supply, a corresponding magnetic field will be generated. Then the magnetic force will attract the moving plate 106 above the electromagnetic device 102 to start to descend, thereby driving the rotating shaft 107 to start rotating inside the bracket 108. At the same time, the rotating moving plate 106 will also pull the spring 105 and make the moving contact 109 start to descend. The descending moving contact 109 will contact the static contact 2 117, so that the circuit is connected. When the circuit of the electromagnetic device 102 is cut off, the generated magnetic force will also disappear. At this time, the spring 105 starts to reset, driving the moving contact 109 to rise, so that When the relay works for a long time or under high load, the temperature inside the housing 101 will continue to rise, thereby driving the metal sheet 116 to expand due to the heat. When the metal sheet 116 expands, it will push one end of the push plate 115 upward, so that the push plate 115 rotates on the surface of the mounting rod 114. At this time, the other end of the push plate 115 will squeeze the static contact 117 downward, causing it to deform and split from the moving contact 109, thereby disconnecting the circuit. When the operator needs to repair or replace the electronic components inside the housing 101, he only needs to press the two blocks 204 to squeeze the two sets of springs 203 and pull them out from the two fixing holes 110, so that the top cover 201 can be quickly removed, reducing the maintenance time.

[0031] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
