[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model provides Figure 1-5 The safe direct-entry three-phase metering box shown in the figure comprises a box body 1, the front of the box body 1 is movably connected with a hinge 2, a transparent shell 3 is fixedly installed on one side of the hinge 2, the inner surface of the transparent shell 3 is provided with a first slide groove 7, the first slide groove 7 is movably connected with a first slider 8, a protective cover 9 is fixedly installed on one side of the first slider 8, the protective cover 9 forms a sliding structure with the transparent shell 3 through the first slider 8, the first slide groove 7 and the first slider 8 are used in conjunction, and the protective cover 9 is provided with a first slide groove 7 and a first slider 8. The cover 9 can slide in a limited position on the transparent shell 3, and a card block 10 is fixedly installed on the top of the protective cover 9. The card block 10 is fixedly installed on one side of the protective cover 9 and is engaged with the second card slot 11 opened on the inner surface of the transparent shell 3. The card block 10 and the second card slot 11 are used in conjunction with each other. The firmness of the protective cover 9 can be enhanced by setting the card block 10 and the second card slot 11. The inner surface of the transparent shell 3 is provided with a second card slot 11. A fireproof baffle 12 is fixedly installed inside the box body 1, and one side of the fireproof baffle 12 is movably connected There is a connecting plate 13, and a second slide groove 16 is provided on the inner surface of the connecting plate 13. A second slider 17 is movably connected inside the second slide groove 16. A safety movable plate 18 is fixedly installed below the second slider 17. A partition plate 19 is fixedly installed inside the box body 1. An inlet hole 20 is provided on the lower side surface of the box body 1, and an outlet hole 21 is provided on the lower side surface of the box body 1. Through the setting of the protective cover 9, the first slider 8 is used to drive the protective cover 9 to slide downward from the first slide groove 7 provided in the transparent shell 3. There is no need to directly disassemble it. The protective cover 9 is directly hung on the transparent shell 3. When the protective cover 9 slides down, it can touch the safety movable plate 18 inside the box body 1. Then, the safety movable plate 18 is slid in the partition plate 19 in the box body 1 through the second slider 17 to leak out related switch parts and also shield adjacent wires. When the inspection and maintenance are completed, the safety movable plate 18 is directly slid back. Such a setting is convenient for maintenance personnel to carry out inspection and maintenance, and can also avoid accidentally touching adjacent wires and causing electric shock.

[0026] like Figure 1 and Figure 2 As shown, a card insertion port 4 is provided on the front surface of the transparent shell 3, buckles 5 are fixedly installed on both sides of the transparent shell 3, and first card slots 6 are provided on the outer surfaces of both sides of the box body 1. Through the arrangement of the buckles 5 and the first card slots 6, the transparent shell 3 and the box body 1 can be snapped together and fixed.

[0027] like Figure 2 , Figure 4 and Figure 5 As shown, one side surface of the fire baffle 12 is provided with a wire clamping groove 14, and bolts 15 are passed through both sides of the connecting plate 13. The wire is placed in the wire clamping groove 14 in the fire baffle 12, and then the connecting plate 13 is engaged with the fire baffle 12, and the bolts 15 are used to pass through the two to limit and sort the wires. This arrangement improves the overall appearance and is also convenient for staff to distinguish.

[0028] like Figure 4 As shown, the safety movable plate 18 forms a sliding structure with the connecting plate 13 through the second slider 17. The second slider 17 is symmetrically arranged with respect to the central axis of the safety movable plate 18. The safety movable plate 18 slides in the partition 19 in the box body 1 through the second slider 17, and the related switch parts are exposed to facilitate the maintenance personnel to carry out inspection and maintenance. At the same time, the adjacent wires are also shielded to prevent the maintenance personnel from touching the adjacent wires and causing electric shock.

[0029] The practical working principle of the present invention is as follows: first, the device is installed to the designated position, and then the transparent shell 3 is turned over and closed by the hinge 2, and then the buckles 5 on both sides of the transparent shell 3 are clamped in the first card slots 6 opened on both sides of the box body 1 to limit and fix the transparent shell 3. When prepayment is required, the payment card is inserted into the box body 1 from the card insertion port 4 outside the transparent shell 3 for prepayment. When the staff or maintenance personnel come to inspect regularly, the protective cover 9 is slid down in the transparent shell 3 through the first slider 8, and then the internal safety movable plate 18 is slid left and right in the connecting plate 13 and the partition 19 by the second slider 17 to leak out the relevant meter and switch, and also to shield the adjacent wires. At this time, the staff and maintenance personnel can conduct inspections. When the inspection and maintenance are completed, the safety movable plate 18 is slid back to the original position through the operation steps just now, and then the protective cover 9 is pushed upward in the transparent shell 3, so that the card block 10 above the protective cover 9 is aligned with the second card slot 11 in the transparent shell 3 for clamping connection, and thus the use process of the safe direct-entry three-phase meter box is completed.

[0030] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
