DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Embodiment 1:

[0029] See also Figure 1-5 A lead sealing mechanism for a metering cabinet comprises a cabinet body 1, a cabinet door 2, a reset mechanism 17, an anti-tampering mechanism and a locking mechanism, the reset mechanism comprises an active pin 3, a rotating disk 4, a first spring 5, a rotating ring 6 and a driven sleeve 7, the active pin 3 is separately connected to the rotating disk 4, the first spring 5 is fixedly connected to the rotating disk 4, the other end of the first spring 5 is fixedly connected to the rotating ring 6, the rotating ring 6 is installed inside the driven sleeve 7 and is rotatably connected to the driven sleeve 7, the anti-tampering mechanism comprises a collection box 8, a rotating shaft 9, an anti-counterfeiting paper 10, a clamping rod 11 and a movable rod 12, the rotating shaft 9 is installed inside the collection box 8 and is rotatably connected to the collection box 8, the two ends of the anti-counterfeiting paper 10 are respectively fixedly connected to the rotating shaft 9 and the clamping rod 11, the clamping rod 11 is separately connected to the movable rod 12, the movable rod 12 is installed inside the driven sleeve 7 and is separately connected to the rotating disk 4.

[0030] In this embodiment, the reset mechanism includes a driving pin 3, a rotating disk 4, a first spring 5, a rotating ring 6 and a driven sleeve 7. When in use, when the driving pin 3 enters the interior of the driven sleeve 7, it first contacts the rotating disk 4, and then, under the pressure of the driving sleeve 13, the rotating disk 4 is squeezed, so that the sliding block 21 on the rotating disk 4 slides inside the steering groove 23, and at the same time compresses the first spring 5 until the sliding block 21 slides to the bottom end of the rotating disk 4. In this process, the first spring 5 is also forced to rotate, so that the rotating ring 6 at the other end of the first spring 5 rotates inside the placement groove 22. After the alignment opening 19 on the rotating disk 4 is rotated ninety degrees, it is aligned with the active pin 3, and the notch 20 passes over the movable rod 12 installed on the driven sleeve 7 during the rotation. When the sliding block 21 slides to the bottom end of the rotating disk 4, it enters the other end of the steering groove 23 in the low-end connecting port. At this time, under the action of the compressed first spring 5, the rotating disk 4 rises linearly, the active pin 3 slides inside the alignment opening 19, and the rotating disk 4 pushes the movable rod 12, and the first limit block 25 slides in the first slide groove 26 inside the driven sleeve 7, so that the sliding of the movable rod 12 is smoother.

[0031] In this embodiment, the anti-tampering mechanism includes a collection box 8, a rotating shaft 9, an anti-counterfeiting paper 10, a card rod 11 and a movable rod 12. When in use, when the card block 16 on the active sleeve 13 enters the driven pin, the card rod 11 is held inside the collection box 8, and then the card rod 11 is pulled out. At this time, as the card rod 11 is pulled out, the inside of the collection box 8 rotates, and the anti-counterfeiting paper 10 on the rotating shaft 9 is pulled out. When the pulled distance is sufficient, the card rod 11 is inserted into the driven sleeve 7, so that the movable rod 12 inside the driven sleeve 7 is inserted into the slot 24 inside the card rod 11.

[0032] In this embodiment, the locking mechanism includes an active sleeve 13, an insertion rod 14, a second spring 15, a block 16 and a guide rod 17. When in use, the active sleeve 13 is installed inside the lock plate 18 on the cabinet door 2, and the driven sleeve 7 is installed inside the lock plate 18 on the cabinet body 1. The guide rods 17 on the active sleeve 13 and the driven sleeve 7 are respectively inserted into the insertion plates, and the guide sleeve 30 on the active sleeve 13 is also quickly inserted into the lock plate 18 to determine the position of the active sleeve 13. As the active sleeve 13 is inserted, the insertion rod 14 also moves accordingly. When the block 16 on the insertion rod 14 contacts the blocking block inside the driven sleeve 7, the second spring 15 is compressed, the block 16 enters the insertion rod 14, and the second limit block 27 slides in the second slide groove 28. When the insertion rod 14 completely enters the driven sleeve 7, the compressed second spring 15 pops out, and under the action of the rotating disk 4 of the first spring 5, the block 16 is in close contact with the blocking sleeve 29 to complete the locking.

[0033] Embodiment 2:

[0034] In summary, when in use, the active sleeve 13 is installed inside the lock plate 18 on the cabinet door 2, and the driven sleeve 7 is installed inside the lock plate 18 on the cabinet body 1, and the guide rods 17 on the active sleeve 13 and the driven sleeve 7 are respectively inserted into the plug plate, and the guide sleeve 30 on the active sleeve 13 is also quickly inserted into the lock plate 18 to determine the position of the active sleeve 13, and with the insertion of the active sleeve 13, the plug rod 14 also moves accordingly, and when the block 16 on the plug rod 14 contacts the blocking block inside the driven sleeve 7, the second spring 15 is compressed, and the block 16 enters the plug rod 14, and The second limit block 27 slides in the second slide groove 28. At the same time, the active pin 3 on the insertion rod 14 enters the interior of the driven sleeve 7, first contacts the rotating disk 4, and then squeezes the rotating disk 4 under the pressure of the active sleeve 13, so that the sliding block 21 on the rotating disk 4 slides inside the steering groove 23, and at the same time compresses the first spring 5 until the sliding block 21 slides to the bottom of the rotating disk 4. In this process, the first spring 5 is also forced to rotate, so that the rotating ring 6 at the other end of the first spring 5 rotates inside the placement groove 22, and the alignment port 19 on the rotating disk 4 rotates ninety degrees and aligns with the active pin 3. The notch 20 passes over the movable rod 12 installed on the driven sleeve 7 during the rotation. When the sliding block 21 slides to the bottom of the rotating disk 4, the card rod 11 is held inside the collection box 8, and then the card rod 11 is pulled out. At this time, as the card rod 11 is pulled out, the inside of the collection box 8 rotates, and the anti-counterfeiting paper 10 on the rotating shaft 9 is pulled out. When the pulled distance is sufficient, the card rod 11 is inserted into the driven sleeve 7 until the rotating disk 4 slides to the bottom in the steering groove 23, and the rotating disk 4 enters the other end of the steering groove 23 in the lower end connection port. At this time, the compressed first spring 5 acts Under the action of the rotating disk 4, the active pin 3 slides inside the alignment opening 19, and the rotating disk 4 pushes the movable rod 12, while the first limit block 25 slides in the first slide groove 26 inside the driven sleeve 7, so that the sliding of the movable rod 12 is more stable, and the movable rod 12 is inserted into the internal notch 24 of the clamping rod 11 to complete the locking of the anti-counterfeiting paper 10. In addition, when the insertion rod 14 completely enters the interior of the driven sleeve 7, the compressed second spring 15 pops out, and under the action of the rotating disk 4 of the first spring 5, the clamping block 16 is in close contact with the blocking sleeve 29 to complete the locking. (The length of the anti-counterfeiting paper 10 is greater than the connection distance between the active sleeve 13 and the driven sleeve 7, in order to prevent the anti-counterfeiting paper 10 from being insufficient in length during the combination of the active sleeve 13 and the driven sleeve 7, so that the lead seal cannot operate normally. Secondly, the extra length can prevent the anti-counterfeiting paper 10 from being easily broken due to tightness.)

[0035] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described one by one here. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
