Embodiment 1

[0022] Figure 1 to Figure 4 It is a safety protection device, comprising a base 1, a support base 2 is fixedly connected to the base 1, a guide rod 3 is inserted on the support base 2, and the guide rod 3 is slidably connected with the support base 2. One end of the guide rod 3 is fixedly connected with an electromagnet, and the guide rod 3 is covered with a tension spring, and one end of the tension spring leans against the support seat 2, and the other end of the tension spring leans against the electromagnet. The electromagnet is connected with a positive pole 4 and a negative pole 5, and the side of the electromagnet away from the guide rod 3 is provided with a magnet, and the magnet is fixedly connected to the base 1, and the base 1 is provided with a push gate device. When the power is on, the gate pushing device pushes down the electric gate; the gate pushing device includes a battery 6, a switch plate 7, a first electrode 8, a second electrode 9, a third electrode 15,...

Embodiment 2

[0027] Figure 5 , Image 6 As shown, the general situation of this embodiment is consistent with that of Embodiment 1, the difference is that the push gate device includes a first electrode 8, a second electrode 9, a battery 6, and an electric push rod 21 for pushing down an electric switch. The first electrode 8 is fixed on the electromagnet, the second electrode 9 is fixed on the base 1, the second electrode 9 is located on the movement path of the first electrode 8, and one pole of the battery 6 is connected to the second electrode. 9 is electrically connected, the other pole of the battery 6 is electrically connected to one pole of the electric push rod 21, and the other pole of the electric push rod 21 is electrically connected to the first electrode 8; the circuit where the electric push rod 21 is located is connected in series There is a delay relay 22; an alarm is connected in series on the circuit where the electric push rod 21 is located.

Abstract

The invention discloses a safety protection device, which relates to the technical field of safety protection devices; it includes a base, a support base is fixedly connected to the base, a guide rod is inserted into the support base, and the guide rod is slidably connected with the support base An electromagnet is fixedly connected to one end of the guide rod, a tension spring is sleeved on the guide rod, one end of the tension spring leans against the supporting seat, and the other end of the tension spring leans against the electromagnet, the The electromagnet is connected with a positive pole and a negative pole. The electromagnet is provided with a magnet on the side away from the guide rod. The gate pusher pushes down the electric gate. The invention proposes a safety protection device. When the power is cut off, the switch pushing device automatically pushes down the switch, thereby preventing the instrument from restarting when the power comes in. In addition, an alarm can be issued; the stability is high.

Description

technical field [0001] The invention belongs to the field of safety protection devices, in particular to a safety protection device capable of automatically turning off an electric switch when power is cut off. Background technique [0002] Sometimes there will be a sudden power outage in the laboratory. At this time, the scientific research personnel need to turn off the instrument manually. If they forget to turn off the instrument and leave the laboratory directly, the next time there is a sudden power call, the experimental equipment may restart. At this time, if there is no personnel in the experiment If it is not in the room, it is easy to cause fire and other accidents. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art that the instrument needs to be powered off manually and is easy to forget, and proposes a safety protection device. Restart. [0004] In order to achieve the above object, the p...
