Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: Reference Figure 1-3A safety pin insertion / removal display and interlocking structure for an equipment includes a main housing 1, a plug 2, and a socket 3. The main housing 1 has multiple fixing holes around its perimeter for easy installation and fixation. A display screen 4 is fixedly connected to the outer wall of the main housing 1 to display the insertion status of the plug 2. A control compartment is located on the side wall of the main housing 1, containing a controller 5, a memory 6, and a battery 7. A maintenance port is located on the top of the control compartment for easy maintenance of the control components. A cover plate 11 is rotatably connected inside the maintenance port to protect the control components. One end of the cover plate 11 is fixedly connected to the inner wall of the maintenance port by a fastening bolt 12.

[0016] The main housing 1 is enclosed on all four sides, with an opening at one end. The plug 2 is slidably inserted into the main housing 1 through the opening. A laser distance sensor 8 is fixedly connected to the end of the plug 2 away from the opening to monitor the movement distance of the plug 2. The top of the plug 2 has a groove, in which an electromagnet 9 is fixedly embedded to drive the iron block 16 to move and achieve interlocking. A lever 10 is fixedly connected to the front side of the plug 2. The lever 10 is perpendicular to the front side of the plug 2 and is used to slide the plug 2. The inner wall of the main housing 1 has a strip-shaped operating port corresponding to the lever 10. The lever 10 extends out of the main housing 1 through the strip-shaped operating port. A slider 13 is fixedly connected to the bottom of the plug 2 to support the plug 2. A slide rod 14 is fixedly connected to the bottom of the main housing 1 to support the plug 2. The slider 13 is provided with a slide opening corresponding to the slide rod 14. Multiple balls 15 are slidably connected in the slide opening. The edges of the balls 15 contact the slide rod 14 to reduce the friction between the slide rod 14 and the inner wall of the slide opening. An interlocking structure corresponding to the electromagnet 9 is slidably connected to the top of the socket 3.

[0017] The socket 3 is provided with a socket corresponding to the plug 2. Multiple locking blocks 20 are fixedly connected to the outer wall of the socket 3. The locking blocks 20 are provided with locking holes to facilitate the installation and fixation of the socket 3.

[0018] The interlocking structure includes an iron block 16, which is slidably connected to a socket 3 via a guide rod 17. The socket 3 is provided with a guide cavity corresponding to the guide rod 17 for supporting the guide rod 17. One end of the guide rod 17 located in the guide cavity is fixedly connected to a limit block 18. A spring 19 is sleeved on the guide rod 17. The two ends of the spring 19 are fixedly connected to the iron block 16 and the inner wall of the socket, respectively, providing a certain elastic support for the guide rod 17.

[0019] In this embodiment, the output terminals of the laser distance sensor 8 and the battery 7 are both connected to the input terminal of the controller 5 to send monitoring signals to the controller 5. The output terminal of the controller 5 is connected to the input terminals of the memory 6, the display screen 4 and the electromagnet 9, respectively.

[0020] In this embodiment, the lever 10 drives the plug 2 to slide, so that the plug 2 is inserted into the socket 3. At the same time, the laser distance sensor 8 can monitor the movement position of the plug 2 and send the monitoring data to the controller 5. After the controller 5 processes the data, it displays it on the display screen 4 to facilitate the judgment of whether the plug 2 is inserted properly. When the plug 2 is inserted into the socket 3, the electromagnet 9 is energized, so that the iron block 16 is inserted into the groove to achieve interlocking.

[0021] In this embodiment, by setting up a display structure and an interlocking structure, the locking status of the safety pin can be viewed, and the locking effect of the safety pin can be improved, thereby effectively expanding the applicability of the safety pin.
