Description

Technical Field

[0001] This utility model belongs to the technical field of electricity metering boxes, and in particular relates to an electricity metering box with a security structure. Background Technology

[0002] An electricity metering box is a special box-type device used to measure electricity consumption. It contains electricity meters, and usually multiple electricity meters are installed inside the electricity metering box.

[0003] Traditional electricity metering boxes are usually made of plastic. In the event of accidental collisions or malicious blows, the plastic shell is not enough to protect the internal electricity metering equipment. In severe cases, the internal electricity metering equipment may be damaged, making it impossible to effectively monitor electricity usage and causing economic losses. Therefore, we propose an electricity metering box with a security structure. Utility Model Content

[0004] The purpose of this utility model is to provide an electricity metering box with a security structure. By setting a protective part, specifically by flipping the sealing cover downward to seal the metal protective box, it can prevent outsiders from opening the sealing cover, effectively protecting the electricity metering box from damage. In the event of an accidental collision, the metal protective box and the sealing cover can effectively prevent external forces from damaging the metering box. This solves the problem that existing traditional electricity metering boxes are usually made of plastic shells, which are easily damaged by accidental collisions or malicious blows.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an electrical energy metering box with a security structure, including a mounting plate, which is used to install on a wall and provides support;

[0007] The protective part is installed on the front of the mounting plate, which is used to protect the power metering equipment.

[0008] The fixing parts are installed on the left and right sides of the protective part, and the fixing parts are used for locking to prevent unauthorized opening; and

[0009] A snap-fit ​​part is installed at the bottom of the protective part and is used to perform a snap-fit ​​function.

[0010] The power metering device is installed inside the protective section, which is an openable structure.

[0011] Furthermore, the protective part includes a metal protective box, a metal block is fixedly connected to the top of the metal protective box, connecting blocks are fixedly connected to the left and right sides of the top of the metal protective box, and conduits and guide plates are fixedly connected to the left and right sides of the metal protective box. An energy metering box is installed inside the metal protective box. The wiring harness to be connected is passed through the conduit into the metal protective box and then into the energy metering box for connection. The conduit can prevent rainwater and other substances from entering the metal protective box.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0038] Please see Figures 1-6As shown, this utility model is an electricity metering box with a security structure, including a mounting plate 1, which is used to install on the wall and provides support.

[0039] Protective part 2 is installed on the front of mounting plate 1, which is used to protect the power metering equipment.

[0040] Fixing part 3, installed on the left and right sides of protective part 2, is used for locking to prevent unauthorized opening; and

[0041] The snap-fit ​​part 4 is installed at the bottom of the protective part 2 and is used to snap-fit.

[0042] The power metering equipment is installed inside the protective section 2, which is an openable structure.

[0043] The protective unit 2 includes a metal protective box 21. A metal block 211 is fixedly connected to the top of the metal protective box 21. Connecting blocks 212 are fixedly connected to the left and right sides of the top of the metal protective box 21. A conduit 213 and a guide plate 214 are fixedly connected to the left and right sides of the metal protective box 21. An energy metering box 23 is installed inside the metal protective box 21.

[0044] A sealing assembly 22 is installed on the front of a metal protective case 21, which is used to open and close the metal protective case 21.

[0045] The conduit 213 is used to thread the wire harness through, and the opening of the conduit 213 is set downward. The guide plate 214 is used to shield the wire harness. The connecting block 212 is used to connect with the sealing assembly 22.

[0046] The fixing part 3 includes two threaded shafts 31 rotatably connected to the left and right sides of the metal protective box 21. A limit ring 311 is fixedly connected to the outer surface of the threaded shaft 31. A limit block 312 is fixedly connected to the side of the threaded shaft 31 facing the inside of the metal protective box 21. A square slot is opened on the side of the threaded shaft 31 facing the outside of the metal protective box 21. A square long key 313 is inserted into the square slot.

[0047] Locking component 32 is installed on the outside of threaded shaft 31 and is used to lock the sealing component 22 after it is closed.

[0048] The sealing assembly 22 includes a sealing cover 221 on the front of the metal protective box 21. A magnetic strip 222 is fixedly connected to the front of the sealing cover 221. Locking plates 223 are fixedly connected to the left and right sides of the back of the sealing cover 221. An insertion hole 224 is opened inside the locking plate 223. A sealing sleeve 225 is fitted on the back of the sealing cover 221. A hinge strip 226 is fixedly connected to the top of the back of the sealing cover 221. The sealing cover 221 is flipped down to seal the metal protective box 21. Then, the operator inserts a square long bar key 313 into the threaded shaft 31 and rotates it clockwise. This causes the moving plate 321 to drive the insertion rod 322 into the insertion hole 224, thereby locking the sealing cover 221. Then, the square long bar key 313 can be pulled out. This method can prevent outsiders from opening the sealing cover 221, effectively protecting the electricity metering box 23 from damage. In the event of an accidental collision, the metal protective box 21 and the sealing cover 221 can effectively prevent external forces from damaging the metering box.

[0049] The sealing cover 221 is hinged to two connecting blocks 212 on the metal protective box 21 via a hinge strip 226 on the back side, thus enabling the sealing cover 221 to flip over. After the sealing cover 221 closes the front of the metal protective box 21, the sealing sleeve 225 will contact the front of the metal protective box 21 to achieve a sealing effect.

[0050] The locking assembly 32 includes a movable plate 321 threadedly connected to the thread on the outer surface of the threaded shaft 31. A rod 322 is fixedly connected to the side of the movable plate 321 facing the inner wall of the metal protective box 21. The rod 322 slides through the metal protective box 21 and extends to the outside.

[0051] The insertion rod 322 serves to limit the movement of the movable plate 321, and the insertion rod 322 is positioned and engaged with the insertion hole 224 on the locking plate 223.

[0052] The snap-fit ​​part 4 includes a fixing block 41 fixedly connected to the bottom of the back of the sealing cover 221, and a triangular locking strip 42 fixedly connected to the bottom of the metal protective box 21.

[0053] The top of the fixing block 41 is spaced from the bottom of the metal protective box 21 so that the sealing cover 221 can be flipped smoothly without affecting the use of the fixing block 41.

[0054] The fixing block 41 has an inner groove 411 inside, and a locking block 412 is slidably connected inside the inner groove 411. Two limiting rods 413 are fixedly connected to the bottom of the locking block 412, and springs 414 are sleeved on the outside of the limiting rods 413. After the sealing cover plate 221 is flipped downward, the sealing sleeve 225 contacts the front of the metal protective box 21, thereby achieving the sealing function. The locking block 412 on the fixing block 41 will move to the rear of the triangular locking strip 42, and the insertion hole 224 on the locking plate 223 will move to the position of the insertion rod 322, which will facilitate the subsequent locking operation.

[0055] The top of the locking block 412 is triangular, which is used to smoothly disengage from the triangular locking strip 42. The bottom of the limiting rod 413 slides through the fixing block 41 and extends to the outside, which is used to make the locking block 412 more stable when it moves. The top of the spring 414 is fixedly connected to the bottom of the locking block 412, and the bottom of the spring 414 is fixedly connected to the bottom of the inner wall of the inner groove 411. The spring 414 is used to push the locking block 412 upward and reset it through elastic force.

[0056] One specific application of this embodiment is:

[0057] In use, the mounting plate 1 is installed on the wall, and the sealing cover 221 is flipped open. At this time, the locking block 412 on the fixing block 41 will disengage from the triangular locking strip 42, thus smoothly opening the sealing cover 221. Since the locking block 412 slides in the inner groove 411, and after the locking block 412 contacts the triangular locking strip 42, it will be pushed into the inner groove 411, and the locking block 412 will squeeze the spring 414, so that the locking block 412 can smoothly disengage from the triangular locking strip 42. After the sealing cover 221 is opened, the hinge strip 226 will rotate on the connecting block 212. When the magnetic strip 222 on the sealing cover 221 of the sealing assembly contacts the metal block 211, it will be fixed by magnetic attraction, keeping the sealing cover 221 in a fixed state. Then, the electricity metering box 23 is installed. Place the wire harness inside the metal protective box 21 and fix it inside the metal protective box 21 with bolts. Pass the wire harness that needs to be connected through the wire conduit 213 into the metal protective box 21 and then into the power metering box 23 for connection. The wire conduit 213 can prevent rainwater and other things from entering the metal protective box 21. After the power metering box 23 is installed, the sealing cover 221 can be flipped down, and then the front of the metal protective box 21 is sealed. When the sealing cover 221 is flipped down, the sealing sleeve 225 will contact the front of the metal protective box 21, thereby achieving the sealing effect. The locking block 412 on the fixing block 41 will move to the back of the triangular locking strip 42, thereby easily fixing the sealing cover 221 and moving the insertion hole 224 on the locking plate 223 to the position of the insertion rod 322.

[0058] The staff then inserts the rectangular key 313 into the threaded shaft 31 and rotates it clockwise, causing the threaded shaft 31 to rotate as well. At this time, the moving plate 321 will move the insertion rod 322 towards the locking plate 223. Since the insertion rod 322 slides on the metal protective box 21, it can limit the movement of the moving plate 321, causing the moving plate 321 to move in a straight line. At this time, the insertion rod 322 will be inserted into the insertion hole 224, thereby locking the sealing cover 221. Then the staff can pull out the rectangular key 313. This method can prevent outsiders from opening the sealing cover 221, effectively protecting the electricity metering box 23 from damage. In the event of an accidental collision, both the metal protective box 21 and the sealing cover 221 are made of metal, which can effectively prevent external forces from damaging the metering box.
