Bolt device with state judgment function

Abstract

The invention discloses a bolt device with a state judgment function. The bolt device comprises a cover plate, a bolt base, a positioning pin, a locking nut, a bolt, a connection plate, a sleeve, a spring and a switch. A lead groove is formed in the bolt base, and the positioning pin penetrates the lead groove to be fixedly connected to the large diameter end of the bolt; and by adjusting the position of the positioning pin in the lead groove, the positioning pin moves along a track of the lead groove, and therefore the bolt can rotate in the axial direction and the radial direction in the bolt base. According to the bolt device, the state judgment function is increased, the positioning pin conducts adjustment at the two ends of the lead groove, extending and retracting of the small diameter end of the bolt are controlled, locking and unlocking of external equipment are achieved, changes of the action state of the large diameter end of the bolt and the trigger end of the switch are achieved, whether a trigger signal exists or not in the switch is detected through an external control system, and whether enabling is carried out on external equipment or not can be further controlled; and the intellectualization level of the external equipment is improved, and hidden dangers caused by man-made misoperation are avoided.

Description

technical field [0001] The invention relates to a plug device with a state judging function, which can be used as a component for judging the running state of mechanical equipment such as a turntable and a machine tool. Background technique [0002] Existing latch device has following shortcoming: [0003] The structure is not compact enough. After the plug is pulled out, it will be separated from the device as a whole, which will easily cause damage to the plug, which is not conducive to use and maintenance. [0004] No status judgment function. The state of the latch is only judged by the operator. If the operator misjudges, that is, when the latch is in the mechanical latch lock state, the electrical system of the equipment is powered on and running, which will damage the equipment and cause losses. [0005] There is a plug with state judgment function, but the switch and its lead wires used for state judgment are exposed, which is easy to be damaged and not beautiful ...

AI Technical Summary

Problems solved by technology

The state of the latch is only judged by the operator. If the operator misjudges, that is, when the latch is in the mechanical latch lock state, the electrical system of the equipment is powered on and running, which will damage the equipment and cause losses.

[0005] There is a pin with state judgment function, but the switch and its lead wires used for state judgment are exposed, easy to be damaged, and not beautiful enough
