Embodiment 1
[0032] Such as figure 1 The light alarm type vibration isolator failure indication device of the present invention shown in the present invention includes a warning light 1, a battery 2 and a connecting sleeve 3, the connecting sleeve 3 is made of insulating material, and the warning light 1 is fixedly arranged on the connecting sleeve 3. At the top, the battery 2 is set in the lumen of the connecting sleeve 3, one electrode of the battery 2 is connected to one pole of the warning light 1 through the connecting circuit 4a, and the other electrode of the battery 2 is connected to the other pole of the warning light 1 through a functional circuit. One pole is connected, the functional circuit includes an open circuit closed circuit control device and two sub-circuits 4b, the open circuit closed circuit control device is arranged between the two sub circuits 4b, and the open circuit closed circuit control device is arranged at the lower part of the connecting sleeve; specifically,...
Embodiment 2
[0038] Such as image 3 The difference between the light alarm type vibration isolator failure indication device of the present invention and the light alarm type vibration isolator failure indication device described in Embodiment 1 is that the conductive connector 5 is made of conductive metal material; in addition, the coupling sleeve A sealing plug 17 is arranged in the lumen of the tube 3, and the sealing plug 17 is arranged between the battery 2 and the open-circuit closed-circuit control device. The sealing plug 17 is specifically made of elastic rubber material; in addition, in this example, the external contact 9, the connection Both the rod 8 and the line connection block 7 are made of conductive metal material, and the surface of the external contact 9 is also provided with an insulating protective sheath 30 .
[0039] Compared with Embodiment 1, in the technical solution described in this example, due to the addition of a sealing plug, it can effectively prevent mo...
Embodiment 3
[0042] Such as Figure 4 The difference between the light alarm type vibration isolator failure indication device of the present invention and the light alarm type vibration isolator failure indication device described in Embodiment 2 is that one electrode of the battery 2 is connected to the alarm light 1 through the connection circuit 4a, and the battery 2 The other electrode of 2 is connected to a sub-circuit 4b of the functional circuit, and the battery 2 is locked in the lumen of the connection sleeve 3 by using the sealing plug 17; in addition, the connection sleeve adopts a detachable split structure, including The upper casing 19 and the lower casing 18 are connected through a threaded structure (not specifically shown in the figure) between the upper casing 19 and the lower casing 18; in addition, an insulating sealing ring is arranged between the connecting rod 8 and the limit ring 10 20; Fourth, the outer surface of the top of the connecting sleeve 3 is provided wit...
