[0026] A safety latch device using the present embodiment is provided with an insert rod 101, an insert plate 102, a sliding rod 103, a groove 104, a sleeve 105, a fixing frame 106, a connecting plate 107, a proximity switch 108, a fixing nut 109, a fixing nut 2 110, a limiting ring 111, a rubber ring 112, a spring 113, a connecting block 114 and a connecting hole 115. The insert plate 102 is slidably connected to the insert rod 101 and wraps the insert rod 101. The sliding rod 103 is fixedly connected to the insert rod 101 and The groove 104 is located at one end of the insertion rod 101, the groove 104 is arranged on the surface of the sliding rod 103, the sleeve 105 is slidably connected with the sliding rod 103 and wraps the sliding rod 103, the fixing frame 106 is fixedly connected with the sleeve 105 and wraps the sleeve 105, the connecting plate 107 is fixedly connected with the fixing frame 106 and is located on the outside of the fixing frame 106, the fixing nut 109 and the fixing nut 2 110 fix the proximity switch 108 on the connecting plate 10 7, the connecting plate 107 connects the proximity switch 108 with the fixing frame 106. When the insertion rod 101 is inserted into the insertion plate 102, the groove 104 will be completely wrapped by the shaft sleeve 105, and the proximity switch 108 will detect the sliding rod 103, and the signal light at the tail thereof will light up. When the insertion rod 101 is not completely inserted into the insertion plate 102, the groove 104 will be exposed to the outside of the shaft sleeve 105. Due to the diameter of the groove 104 on the surface of the sliding rod 103, the sliding rod 103 is The minimum is that the groove 104 on the surface of the sliding rod 103 is farthest from the proximity switch 108, so the proximity switch 108 can detect the sliding rod 103 but cannot detect the groove 104, and the signal light at the tail of the proximity switch 108 will not light up, that is, by judging whether the signal light at the tail of the proximity switch 108 is on, it can be judged whether the insertion rod 101 is fully inserted into the insertion plate 102, thereby solving the problem that the existing safety bolt device cannot automatically display whether the bolt is fully inserted and fixed.
