a protective cover 4 is arranged above the protective shell 6, the upper end of the conversion induction block 2 extends out of the protective cover 4 from the protective shell 6, and a sealing ring 3 is arranged between the conversion induction block 2 and the protective cover 4;
the bottom of the protective shell 6 is provided with a connector seat 9, the bottom of the connector seat 9 is provided with a cable leading-out connector 10, and the connector seat 9 is connected with the proximity switch 8 and the cable leading-out connector 10;
the striker 1 is in contact with the conversion sensor block 2.
The conversion induction block 2, the sealing ring 3, the protective cover 4, the protective shell 6, the connector base 9 and the cable lead-out connector 10 form a sealed cavity.
The top of the conversion sensing block 2 is an inclined plane.
Fig. 1: the axis of the collision block 1 is parallel to the axis of the protection mechanism, and the movement direction of the collision block 1 is perpendicular to the axis of the protection mechanism.
Fig. 2: the axis of the collision block 1 is vertical to the axis of the protection mechanism, and the movement direction of the collision block 1 is vertical to the axis of the protection mechanism;

working principle:
the moving part drives the collision block 1 to move to the conversion sensing block 2 of the protection mechanism along the horizontal direction, and after the collision block contacts with the conversion sensing block, the conversion sensing block 2 moves downwards under the action of the inclined plane, the compression spring 5 deforms the conversion sensing block until the conversion sensing block 2 moves to the sensing range of the proximity switch 8, and the proximity switch 8 is triggered to work. When the collision block 1 moves reversely, the contact surface of the collision block 1 and the conversion sensing block 2 is separated, the conversion sensing block 2 is restored to the initial position under the action of the resilience force of the spring 5, and is separated from the proximity switch 8, and the trigger signal is released. The main function of the connector base 9 and the cable lead-out connector 10 is to protect the proximity switch 8 and the cable, so that the proximity switch 8 is separated from the external environment.
The utility model enables protection of the proximity switch 8 when the moving part exceeds the set movement limit. The proximity switch 8 is provided with a collision block 1, a conversion sensing block 2, a sealing ring 3, a protective cover 4, a spring 5, a protective shell 6, a locking nut 7, a joint seat 9 and a cable leading-out joint 10 at the periphery, so that the proximity switch 8 is not in direct contact with the collision block 1. Not only ensure that the proximity switch 8 is not triggered by mistake due to the interference of scrap iron, greasy dirt and rainwater in the use environment, but also avoid the damage of the proximity switch 8 due to the over-limit operation.
The conversion induction block 2, the sealing ring 3, the protective cover 4, the protective shell 6, the connector seat 9 and the cable leading-out connector 10 form a sealed cavity, and the proximity switch 8 is fixed in the sealed cavity by using the locking nut 7. In the free state, the conversion sensing block 2 is far away from the sensing range of the proximity switch 8 under the action of the spring 5, and is in a non-triggering state.
When the collision block 1 is close to the conversion induction block 2, the spring 5 is elastically deformed under the drive of the collision block 1 and the conversion induction block 2, the conversion induction block 2 enters the induction range of the proximity switch 8, and the proximity switch 8 is triggered to give an alarm. When the collision block 1 is far away from the conversion sensing block 2, the spring 5 resets, the conversion sensing block 2 is pushed to be separated from the sensing range of the proximity switch 8, and the alarm is released.
The proximity switch 8 is not in direct contact with the striker 1, and transmits sensing information through an intermediate transition device, wherein the intermediate transition device is a conversion sensing block 2 and spring 5 assembly.
The conversion sensing block 2 and the spring 5 are added between the collision block 1 and the limit switch 8, the conversion sensing block 2, the spring 5, the limit switch 8 and the like are integrated into a whole, under the normal state, the spring 5 is in a small compression state under the action of the protective cover 4 and the protective shell 6, when the collision block 1 is close to the conversion sensing block 2, the compression amount of the spring 5 is increased, so that the conversion sensing block 2 enters the sensing area of the proximity switch 8, and the sensing switch triggers an alarm; after the collision block 1 is separated from the conversion sensing block 2, the spring 5 is reset, the conversion sensing block 2 leaves the sensing area of the proximity switch 8, and the sensing switch alarms and is released. Meanwhile, a sealing ring is arranged at the contact position of the protective cover 4 and the conversion induction block 2, and a cable lead-out connector 10 arranged on the connector seat 9 is also a sealing type connector, so that the dustproof and waterproof protection effect on the proximity switch is realized.
The overrun protection sensing device not only can play a role of the proximity switch 8, but also has stronger reliability and environmental adaptability compared with the common proximity switch 8.
