Technical Field

[0001] The utility model relates to the field of circuit safety switches, and particularly to an Internet of Things remote safety switch. Background Art

[0002] A safety switch is a safety device that protects personnel in mechanical production equipment. When sensors such as gratings receive signals of personnel entering or contacting, they send a disconnection signal to the safety switch, which urgently cuts off the equipment circuit to prevent the production equipment from causing harm to personnel.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] During specific implementation: As Figures 1-4 shown, an Internet of Things remote safety switch includes: an outer shell 1, a pressing rod 2 is arranged on the inner wall of the outer shell 1, and a wire interface 3 is fixedly connected to the inner wall of the outer shell 1; an adsorption control mechanism 4 for controlling the on / off of the wire interface 3 is arranged in the outer shell 1; an emergency circuit breaking mechanism 5 for physically unlocking the adsorption control mechanism 4 is arranged on one side of the outer shell 1; wherein, the adsorption control mechanism 4 includes a communication component 401 arranged in the outer shell 1, a disconnection component 402 is arranged on one side of the communication component 401, the wire interface 3 can be connected to a circuit, the communication component 401 receives a remote control signal to connect the circuit of the wire interface 3, when the communication component 401 receives a disconnection instruction, the communication component 401 is powered off, and at the same time the disconnection component 402 pulls the communication component 401 to automatically disconnect, realizing remote control, and at the same time the emergency circuit breaking mechanism 5 can realize physical control for power off in case of emergency.

[0023] As Figure 2 and Figure 3As shown, the connected component 401 includes two mounting rods 4011 fixedly connected to the inner upper wall of the housing 1. At the lower ends of the two mounting rods 4011, power-on seats 4015 are fixedly connected. The two power-on seats 4015 are respectively connected and communicated with the two wire interfaces 3. At the lower end of the pressing rod 2, a power-on strip 4012 is fixedly connected. The power-on strip 4012 is attached to the lower end of the power-on seat 4015. When in use, when the power-on strip 4012 is attached to the power-on seat 4015, the circuit is turned on. When the power-on strip 4012 is away from the power-on seat 4015, the circuit can be disconnected. At the upper end of the housing 1, a remote electromagnetic adsorption component 4013 is fixedly connected. The adsorption end of the remote electromagnetic adsorption component 4013 fixedly penetrates the inner upper wall of the housing 1 and extends inward. At the lower end of the power-on strip 4012, a connecting plate 4014 is fixedly connected. The remote electromagnetic adsorption component 4013 is magnetically attracted to the connecting plate 4014. When the remote electromagnetic adsorption component 4013 is powered on, it adsorbs the connecting plate 4014, and the connecting plate 4014 pushes the power-on strip 4012 to be attached to the power-on seat 4015 to conduct the circuit. The remote electromagnetic adsorption component 4013 includes a remote control chip and a magnetic adsorption part. For those skilled in the art, the remote electromagnetic adsorption component 4013 is prior art and will not be elaborated here.

[0024] As Figure 3 and Figure 4As shown, the disconnecting component 402 includes a spring 4021 fixedly connected to the lower inner wall of the housing 1. The upper end of the spring 4021 is fixedly connected to the connecting plate 4014. When the remote electromagnetic adsorption component 4013 is powered off, the spring 4021 pulls the connecting plate 4014 and the energizing bar 4012 downward at this time to disconnect the power supply. The telescopic rod 4022 is fixedly connected to the lower inner wall of the housing 1, and the upper end of the telescopic rod 4022 is fixedly connected to the connecting plate 4014. The spring 4021 is sleeved on the circumferential surface of the telescopic rod 4022. When the spring 4021 pulls the connecting plate 4014 to disconnect or extends due to adsorption, the spring 4021 is prone to lateral elastic deformation and damage. The telescopic rod 4022 supports the spring 4021, making it difficult for the spring 4021 to undergo elastic deformation. The emergency circuit breaker mechanism 5 includes a connecting ring 501 slidably connected to the surface of the pressing rod 2. The connecting ring 501 is rotatably connected to the inner wall of the housing 1. The upper end of the connecting ring 501 is fixedly connected to an energizing block 503. The battery holder 502 is fixedly connected to the upper end of the housing 1. The energizing block 503 is connected to the battery holder 502. The connecting ring 501 is electrically connected to the remote electromagnetic adsorption component 4013. When manual disconnection is required, the pressing rod 2 is rotated. At this time, the energizing block 503 no longer contacts the battery holder 502 to be energized, the connecting ring 501 loses power, and the current is disconnected from the remote electromagnetic adsorption component 4013. At this time, the remote electromagnetic adsorption component 4013 is powered off, and the spring 4021 outputs a pulling force. At the same time, the pressing rod 2 is manually pressed downward, and the pressing rod 2 pushes the energizing bar 4012 and the connecting plate 4014 downward to disconnect the current. A battery is installed inside the battery holder 502, and the remote electromagnetic adsorption component 4013 can be powered by contacting the remote electromagnetic adsorption component 4013 through the energizing block 503 and the connecting ring 501. The shielding cover 504 is fixedly connected to the upper end of the housing 1. The shielding cover 504 is arranged above the energizing block 503 and the connecting ring 501. The emergency circuit breaker mechanism 5 can be shielded and protected by the shielding cover 504 to prevent damage and prevent electrical contact.

[0025] When the utility model is in use and the on-off control of the device circuit is carried out, the wire interface 3 is connected to both ends of the circuit at this time. At this time, the remote electromagnetic adsorption component 4013 is energized to adsorb the connecting plate 4014, and the connecting plate 4014 pushes the energizing bar 4012 to fit the energizing seat 4015 to conduct the circuit. When the remote electromagnetic adsorption component 4013 receives the disconnection instruction, the circuit of the remote electromagnetic adsorption component 4013 is disconnected. The connecting plate 4014 and the energizing bar 4012 are pulled down by the spring 4021 to disconnect the power supply. At this time, the connecting component 401 is automatically disconnected to achieve remote control. When manual disconnection is required, rotate the pressing rod 2 downwards. At this time, the energizing block 503 no longer contacts the battery seat 502 to be energized, and the connecting ring 501 loses power, and the current is disconnected from the remote electromagnetic adsorption component 4013. At this time, the remote electromagnetic adsorption component 4013 is powered off, and the spring 4021 outputs a pulling force. At the same time, manually press down the pressing rod 2, and the pressing rod 2 pushes the energizing bar 4012 and the connecting plate 4014 to descend to disconnect the current, realizing the emergency power-off function. At this time, the device can remotely receive signal connection control and at the same time retain physical power-off to achieve protection for personnel.

[0026] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
