[0036] The following is combined with Figure 1-6 This application is described in further detail.

[0037] The embodiment of the present application discloses a metal electric meter box. Embodiment 1

[0038] This embodiment discloses a metal electric meter box, referring to Figure 1, including a box body 1, one or more box doors 11 are arranged on the box body 1, the box body 1 and the box doors 11 are both made of metal materials, and two box doors 11 are arranged in this embodiment, a vertical side of the box door 11 is hinged to the box body 1 through a hinge 12, and a smart lock 2 is arranged on the side of the box door 11 away from the hinge 12, and a QR code layer 3 is fixedly arranged on the outer surface of the smart lock 2. After the QR code on the QR code layer 3 is recognized by a mobile phone as a scanning terminal, and the account information of a professional is logged in, after correct login, the smart lock 2 is opened, so that the number of times the meter box is opened or the person who opens it can be registered, thereby improving the safety of the meter box. At the same time, since the smart locks 2 are all opened through the same scanning terminal, it is possible to avoid the difficulty of unlocking caused by forgetting or not taking the corresponding key in time.

[0039] refer to Figure 2 The box body 1 and the door 11 are provided with hanging ears 4, and the hanging ears 4 are provided with through holes 41. When the door 11 is in the state of closing the box body 1, the hanging ears 4 on the box body 1 and the door 11 are arranged opposite to each other, and the through holes 41 on the two hanging ears 4 are in a state of communication. The smart lock 2 includes a lock body 21 and a U-shaped locking rod 22, the U-shaped locking rod 22 is connected to the lock body 21, and the U-shaped locking rod 22 is used to penetrate into the through holes 41 of the two hanging ears 4. The two-dimensional code layer 3 is fixed on the outer wall of the lock body 21. A connecting soft rope 5 is fixedly connected to the lock body 21, and the connecting soft rope 5 can be made of steel wire rope. One end of the connecting soft rope 5 is fixed on the lock body 21, and the other end is fixed on the box body 1, and is close to the position where the hanging ear 4 is set on the box body 1, so that the length of the connecting soft rope 5 can facilitate the connection of the smart lock 2 to the hanging ear 4, while avoiding the smart lock 2 from being connected to the hanging ear 4 corresponding to other smart locks 2, so that the smart lock 2 on the corresponding box door 11 can correctly correspond to the corresponding box body 1, so as to avoid the inability to record the maintenance status of the electric meter in the box body 1 due to the confusion of the correspondence between the smart lock 2 and the box body 1, and at the same time prevent the loss of the smart lock 2.

[0040] refer to Figure 3, one end of the connecting cord 5 connected to the lock body 21 can be connected by welding, and one end of the connecting cord 5 connected to the box 1 is provided with a stud 51, one end of the stud 51 penetrates the side wall of the box 1, and one end of the stud 51 located in the box 1 is provided with a nut 52, and the nut 52 is threadedly connected with the stud 51, so that the stud 51 can be fixed on the box 1 after the nut 52 is tightened, and the connecting cord 5 is welded and fixed on the stud 51. Since the stud 51 can be removed from the box 1 through the nut 52, the smart lock 2 can be brought with the connecting cord 5, and then the smart lock 2 can be fixed on the box 1 through the stud 51, which is convenient for the installation of the smart lock 2. At the same time, a power cord 6 is also connected to the lock body 21, and one end of the power cord 6 extends from the side wall of the box 1 to the inside of the box 1, which is used to introduce power from the inside of the box 1 to power the smart lock 2. The end of the power cord 6 away from the box 1 penetrates into the lock body 21 from the bottom of the lock body 21 to supply power to the smart lock 2 to prevent the smart lock 2 from being unable to unlock due to insufficient power. The portion of the power cord 6 located outside the lock body 21 and the box 1 is configured in a spiral spring shape, and the length of the power cord 6 is greater than the length of the connecting cord 5. The portion where the power cord 6 penetrates the box 1 can be arranged close to the stud 51, so that the power cord 6 will not be affected by the gravity of the smart lock 2, thereby making the power cord 6 safer.

[0041] refer to Figure 4 The interior of the lock body 21 is a hollow structure. A lock tongue 23 and a driving component 24 for driving the lock tongue 23 to move are arranged inside the lock body 21. The driving component 24 is connected to a battery 25. The battery 25 is fixed inside the lock body 21 and is electrically connected to the power cord 6 so that the power cord 6 supplies power to the battery 25. Even if the power input inside the meter box is damaged, the battery 25 can still have enough power to support professional personnel for maintenance, thereby avoiding the situation where the smart lock 2 cannot be opened when the power cord 6 has no power supply. The lock tongue 23 is slidably connected to the inside of the lock body 21, and the end of the lock tongue 23 is used to be inserted into the notch of the U-shaped lock rod 22. The drive assembly 24 includes a drive motor 241 and a drive screw 242. The output shaft of the drive motor 241 is coaxially fixed with the drive screw 242. The drive motor 241 can be connected to the battery 25 through a control module, so that the control module is used to control the operation of the drive motor 241. The drive screw 242 is threadedly connected to the lock tongue 23, and the length direction of the drive screw 242 is parallel to the sliding direction of the lock tongue 23. When the drive screw 242 rotates, the lock tongue 23 moves out of the notch of the U-shaped lock rod 22, so that the U-shaped lock rod 22 can be opened from the lock body 21.

[0042] refer to Figure 4 and Figure 5A slide groove 26 is provided on the inner wall of the lock body 21, and a sliding seat 27 is slidably connected in the slide groove 26. The sliding seat 27 is configured to be L-shaped as a whole. A part of the sliding seat 27 extends out from the slide groove 26 and is used to fix and install the drive motor 241. The length direction of the slide groove 26 is parallel to the sliding direction of the lock tongue 23, and a return spring 28 is provided in the slide groove 26. One end of the return spring 28 abuts against the end of the slide groove 26, and the other end abuts against the sliding seat 27, so that the force direction of the return spring 28 on the sliding seat 27 points to the notch of the U-shaped lock rod 22. A cover plate 29 is provided at the opening of the slide groove 26, and the cover plate 29 is fixed to the lock body 21 by screws, so that the cover plate 29 cooperates with the slide groove 26 to keep the sliding seat 27 and the return spring 28 in the slide groove 26. When in use, the sliding seat 27 abuts against one end of the sliding groove 26 under the action of the return spring 28, and the driving motor 241 can drive the locking tongue 23 to normally open the U-shaped locking rod 22, and then the driving motor 241 rotates in the opposite direction to move the locking tongue 23 to a position where the U-shaped locking rod 22 can be locked. When the U-shaped locking rod 22 is locked, the end of the U-shaped locking rod 22 first abuts against the inclined surface on the locking tongue 23 to compress the return spring 28, thereby causing the locking tongue 23, the driving screw 242, the driving motor 241 and the sliding seat 27 to move at the same time, thereby facilitating the locking of the U-shaped locking rod 22.
