DETAILED DESCRIPTION
[0025] The utility model embodiment is described in detail below in combination with the drawings in the embodiment.
[0026] EMBODIMENT
[0027] Please refer to Figures 1-4This embodiment provides an intelligent grounding interlocking device, including a base 1 and a top cover 2. One side of the top cover 2 is rotatably mounted on the top of the base 1 via a hinge 14. The bottom of the top cover 2 has two upper slots 3 spaced apart, and the top of the base 1 has two lower slots 4 spaced apart. The longitudinal cross-section of both the upper slots 3 and the lower slots 4 is semi-circular. Figure 1 As shown, after the top cover 2 is put on, two circular through holes can be formed, and the two ends of the ground wire 18 are fixed by passing through the two circular through holes respectively.
[0028] The bottom of the top cover 2 is provided with a locking block 5, and the locking block 5 is provided with a horizontal locking hole 6; the top of the base 1 is provided with a locking slot 7, and the locking block 5 is embedded in the locking slot 7; the base 1 is provided with a horizontal guide slide hole 8 that communicates with the locking slot 7, and a locking tongue block 9 is slidably provided in the guide slide hole 8. The top of the locking tongue block 9 is provided with an inclined surface 10, and one end of the locking tongue block 9 is slidably inserted into the locking hole 6. The base 1 is provided with a drive assembly for driving the locking tongue block 9 to slide along the guide slide hole 8.
[0029] The driving assembly includes a push-pull electromagnet 11, which consists of a coil, a moving iron core 12, a return spring, a stationary iron core, and a power controller. The moving iron core 12 and the stationary iron core are attracted together over a long distance to achieve linear reciprocating motion of the moving iron core 12. In normal operation, the moving iron core 12 extends outward from the push-pull electromagnet 11 under the force of the return spring. When the push-pull electromagnet 11 is energized, the moving iron core 12 and the stationary iron core interact to retract the moving iron core 12 into the push-pull electromagnet 11, thus achieving linear reciprocating motion of the moving iron core 12.
[0030] Locking tongue block 9 is located at one end of moving iron core 12, such as Figure 3 As shown, when the push-pull electromagnet 11 is energized, the moving iron core 12 slides to the right and retracts. At this time, the moving iron core 12 drives the locking tongue block 9 to slide to the right and move away from the locking insert block 5. After the locking is released, the locking insert block 5 can slide out from the locking slot 7. When locking is required, after the top cover 2 is closed, the push-pull electromagnet 11 is de-energized. At this time, the moving iron core 12 slides to the left to reset. The moving iron core 12 pushes the locking tongue block 9 to slide to the left and insert it into the lock hole 6 for locking. The operation is convenient. Since the top cover 2 is rotatable, when the top cover 2 is closed, the locking insert block 5 rotates with the top cover 2 and inserts into the locking slot 7. Therefore, the locking slot 7 is set to be slightly larger than the locking insert block 5 to prevent the locking insert block 5 from contacting the slot wall of the locking slot 7 when it rotates and inserts into the locking slot 7.
[0031] The base 1 is provided with a processor and a card reader, and the card reader and the push-pull electromagnet 11 are electrically connected with the processor. The base 1 is provided with a storage battery, which is electrically connected with the processor, and the storage battery is used for supplying power to each electrical equipment. The side wall of the base 1 is provided with a card swiping identification area 13, and the card reader is located in the card swiping identification area 13, so as to facilitate the staff to swipe the card in this area. The processor of the embodiment can adopt an AT89S51 chip, and the card reader can adopt an RFID card reader with a model of R20D / R20C. The card reader is used for identifying the electronic identification card and transmitting the read data to the processor, wherein the electronic identification card can adopt an IC card which can be read by the card reader. The staff can swipe the card in the card swiping identification area 13 through the IC card, and the correct IC card information can be input into the card reader for storage, and the top cover 2 can be opened only after the card swiping is correct.
[0032] In actual use, when it is necessary to lock the ground wire, the staff holds the IC card to swipe the card in the card swiping identification area 13. After the card reader identifies that it is a correct IC card, the card reader transmits an electric signal to the processor, the processor supplies power to the push-pull electromagnet 11, and the moving iron core 12 of the push-pull electromagnet 11 drives the lock tongue block 9 to slide to the right together. At this time, as shown in Figure 2 and Figure 4 the top cover 2 can be rotated to be opened, the two ends of the ground wire 18 are respectively inserted through the upper card slot 3 and the lower card slot 4, then the top cover 2 is rotated and covered on the top of the base 1, and the locking plug 5 is rotated and inserted into the locking slot 7; after the push-pull electromagnet 11 is powered off, the moving iron core 12 drives the lock tongue block 9 to slide to the left together, at this time, the lock tongue block 9 is inserted into the lock hole 6 of the locking plug 5 for locking, and at this time, the two ends of the ground wire 18 are fixed by the ground wire locking device.
[0033] When the ground wire 18 needs to be taken out, the card can be swiped according to the above operation. After the card is swiped, the top cover 2 is rotated to be opened, and then the ground wire 18 can be taken out. In this way, the ground wire locking device provided in the application can realize the locking and taking out of the ground wire 18 only by swiping the card. The process of locking and taking out the ground wire is simple in operation, time-saving and labor-saving. After the ground wire is locked, reliable management of the ground wire is ensured, and the safe operation of the equipment and the personal safety of the operating personnel are ensured.
[0034] As shown in Figure 3 in some embodiments, a containing groove 15 in communication with the locking slot 7 is vertically arranged in the base 1, and the containing groove 15 is located at the bottom of the locking slot 7; a push block 16 is slidably arranged in the containing groove 15, and the push block 16 abuts against the bottom of the locking plug 5. An upward pushing spring 17 is arranged in the containing groove 15, the top end of the upward pushing spring 17 is connected with the push block 16, and the bottom end of the upward pushing spring 17 is connected with the base 1.
[0035] The utility model discloses a push spring 17 and push block 16 are set up, when cover top cover 2, locking plug 5 press down push block 16, at this time, push spring 17 accumulates elastic potential. Such when opening top cover 2, when the lock tongue block 9 slides out lock hole 6 to the right after swiping, under the elastic force of push spring 17 upwards, can push locking plug 5 to move a certain distance upwards through push block 16, at this time, lock hole 6 and lock tongue block 9 are mutually staggered, and top cover 2 slightly inclines upwards, at this time, even if push-pull electromagnet 11 power-off lock tongue block 9 also can not slide into lock hole 6, and top cover 2 is convenient to open.
