DETAILED DESCRIPTION

[0022] The utility model will be further explained in connection with the drawings and examples.

[0023] Please refer to Figures 1-5The utility model provides a kind of embodiment: banana screen fault monitoring early warning device, including base 1, banana screen 2 located above base 1, banana screen 2 includes support seat 22, elastic rod 21 located above support seat 22, there is screen body 23 by elastic rod 21 connection, the early warning device that contact base 1 and support seat 22 are contacted is, early warning device includes contact lever 32, contact lever 32 one end sticks support seat 22, contact lever 32 other end sticks and has metal spring 31, metal spring 31 side away from contact lever 32 is equipped with positive cable 391, positive cable 391 located in the region of metal spring 31 is disconnected design, positive cable 391 exposed internal metal wire core in the region of metal spring 31, positive cable 391 side is connected with the anode of power supply 39, other side is connected with the anode of luminous stick 34, the cathode of power supply 39 is connected with negative cable 392, the other side of negative cable 392 is connected to the cathode of luminous stick 34, contact lever 32 is pressed against support seat 22 by contact lever 32, when support seat 22 displacement, it will push contact lever 32 and produce movement, after contact lever 32 is pushed to the inside of box body 38, contact lever 32 towards the side of box body 38 will extrude metal spring 31 to the metal wire core of positive cable 391 exposure, so that power supply 39 and luminous stick 34 form closed loop, luminous stick 34 will emit early warning red light, and the identification banana screen 2 displacement fault occurs.

[0024] Please refer to Figures 1-4 In the embodiment, contact lever 32 is inserted in the outside of box body 38, and the box body 38 has an opening 381 corresponding to the cross section of the contact lever 32. When the support seat 22 moves, the support seat 22 can press the contact lever 32 to move inwardly of the box body 38, and the opening 381 can limit the one-way movement of the contact lever 32. When the banana screen 2 is displaced, it will only move inwardly of the box body 38. The bottom of the box body 38 is provided with a support plate 37 extending toward the side with the opening 381. The support plate 37 can be installed on the bottom of the base 1. The middle of the contact lever 32 is provided with a radial flange 321. The spring 33 can be inserted into the contact lever 32. The side of the contact lever 32 with the spring 33 is inserted into the opening 381, and the spring 33 can contact the outside of the flange 321 and the box body 38. The spring 33 can generate a pushing force on the contact lever 32 through the flange 321. The inside of the box body 38 is provided with the metal spring 31 corresponding to the opening 381. One side of the metal spring 31 is connected with a fixing seat 36 connected with the inside of the box body 38. When the support seat 22 does not move, the metal spring 31 needs to maintain a certain distance from the positive cable 391. The metal spring 31 is suspended in the inside of the box body 38, so that the metal spring 31 can deform greatly. The side of the contact lever 32 away from the spring 33 can be pressed toward the support seat 22 through the spring 33, so that the contact lever 32 is pressed against the support seat 22. The contact lever 32 will not shake slightly, so that the metal spring 31 contacts the positive cable 391.

[0025] Please refer to Figures 2-5 In the embodiment, the box body 38 is provided with two openings 381 along the length direction, corresponding to the two sides of the support seat 22. The two openings 381 are arranged on the two sides of the support seat 22, so that the device has higher sensitivity in identifying the deviation of the banana screen 2. The light-emitting rod 34 can emit red light. The height of the light-emitting rod 34 is higher than that of the box body 38. The light-emitting rod 34 emits red light. The red light has a more eye-catching ability, so that people can find the danger in time. The light-emitting rod 34 is higher than the box body 38 to avoid the shielding of the box body 38.

[0026] When working, the screen body 23 vibrates, and the elastic rod 21 transmits part of the vibration force to the support seat 22, which is easy to cause the support seat 22 to deviate and fail. The box body 38 is installed on the side of the base 1 through the support plate 37. The support plate 37 has a long hole, which can adjust the distance between the box body 38 and the support seat 22. The specific distance is that the contact rod 32 is pressed against the support seat 22 through the spring 33 on one side of the flange 321. The other side is attached to the metal spring 31 inside the box body 38. However, the metal spring 31 is not in contact with the positive cable 391. The positive cable 391 is disconnected at the position corresponding to the metal spring 31, and the metal wire core is exposed by stripping the wire skin. The metal spring 31 controls the on-off of the positive cable 391 line relative to the switch. When the support seat 22 deviates, the support seat 22 will push the contact rod 32 into the inside of the box body 38. The spring 33 is compressed and cannot reset. The contact rod 32 pushes the metal spring 31 to move to the inside of the box body 38. The metal spring 31 is attached to the exposed metal wire core of the positive cable 391. The loop between the light-emitting rod 34 and the power supply 39 is closed. The power supply of the power supply 39 flows from the positive electrode to the positive electrode of the light-emitting rod 34 through the positive cable 391, and then flows out from the negative electrode of the light-emitting rod 34, and then returns to the power supply 39 through the negative cable 392 to form a closed loop. The light-emitting rod 34 emits red light as a warning of the deviation of the banana screen 2. The positive cable 391 and the negative cable 392 are hard wires.

[0027] Through the above steps, the contact rod 32 is pressed against the support seat 22. When the support seat 22 deviates, it will push the contact rod 32 to move. After the contact rod 32 is pushed to the inside of the box body 38, the side of the contact rod 32 towards the box body 38 will extrude the metal spring 31 to the exposed metal wire core of the positive cable 391. In this way, the power supply 39 and the light-emitting rod 34 form a closed loop. The light-emitting rod 34 will emit a warning red light to indicate that the banana screen 2 has deviated and failed. The structure of the prior art does not have a fault detection and warning function. When the banana screen 2 vibrates and the screw deviates due to loosening, it cannot be monitored in time, which is prone to danger.
