Description

Technical Field

[0001] The invention relates to the technical field of meter boxes, in particular to an electric energy meter box with a security structure. Background Art

[0002] An energy meter is a device used to measure and record electricity consumption. It is usually installed in the power supply system and can monitor data such as current, voltage and power in real time and convert this information into energy usage. The data from the meter can be used for electricity bill settlement, energy management and power system monitoring. It has high accuracy and reliability and is suitable for a variety of commercial and industrial sites.

[0003] The Chinese patent with patent announcement number CN211785710U discloses an electric energy meter box with a security structure, which includes an outer box and an inner box located inside the outer box; the outer box and the inner box are connected by a spring device; the spring device is arranged at each vertex of the inner box and connected to each vertex of the outer box; the spring device includes an irregularly shaped spring cable and a plurality of rolling shafts sleeved on the spring cable. The patent provides an electric energy meter box with a security structure, which can effectively prevent foreign objects from contacting the circuit and electronic devices inside the box while ensuring the heat dissipation effect, and has a shock absorption effect.

[0004] However, the current electricity meter box has the following problems: after long-term use, the mounting bracket of the electricity meter box is affected by the external environment, the mounting bracket bolts of the electricity meter box will inevitably loosen, and there is a gap between the electricity meter box and the wall, which increases the possibility of the electricity meter box shaking due to external force. Long-term shaking will cause mechanical shocks to the components or circuits inside the meter box, reducing the service life of the equipment. Therefore, we propose an electricity meter box with a security structure. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an electric energy metering box with a security structure, which solves the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an electric energy meter box with a security structure, comprising an outer box of a meter box, an inner box of a meter box is fixed inside the outer box of the meter box, an I-shaped bracket is fixed on the rear side of the outer box of the meter box, a box door is hinged on the front side of the outer box of the meter box, an anti-sway device is arranged on the front side of the I-shaped bracket, the anti-sway device comprises two hollow plug posts, both of the two hollow plug posts are penetrated and slidably installed on the front side of the I-shaped bracket, and a circular hole for accommodating the two hollow plug posts is opened on the rear side of the inner wall of the outer box of the meter box, a spring is arranged between the hollow plug posts and the inner wall of the outer box of the meter box, an internal threaded plate is fixed on the front side of the two hollow plug posts, the internal threads of the two internal threaded plates are connected with screws, a rotating column is rotatably installed on the rear end of the screw, a triangular push plate is fixed on the rear end of the rotating column, and the triangular The top and bottom inclined surfaces of the push plate are both slidably installed with card plates, and the two card plates pass through the top and bottom of the hollow column respectively. An anti-theft device is arranged under the hollow column below, and the screw pushes the rotating column and the triangular push plate to move accordingly. The inclined surface of the triangular push plate pushes the card plate to move along the through-opening of the hollow column in the direction away from the center of the hollow column, so that the card plate clamps the hollow column to the wall. When the bolts of the I-shaped bracket are loosened due to long-term use due to the influence of the external environment, under the action of the spring force corresponding to the hollow column, the spring of the hollow column will push the outer box of the meter box close to the wall. When a vandal wants to dismantle, steal and destroy the outer box of the meter box, the vandal removes the bolts of the I-shaped bracket to remove the outer box of the meter box. The hollow column will limit the position of the outer box of the meter box, making it inconvenient for the vandal to remove the outer box of the meter box from the wall.

[0007] According to the above technical solution, a rubber ring is fixed to the outside of the rotating column, and the outer wall of the rubber ring contacts the inner wall of the hollow column. The screw rod is moved toward the inside of the hollow column under the thread action of the internal thread plate, and the rubber ring seals the internal space of the hollow column.

[0008] According to the above technical scheme, the anti-theft device includes an alarm device, which is fixed to the bottom of the inner wall of the outer box of the meter box, and wires are fixed on both sides of the top of the alarm device, and side contact rods are fixed on the top front sides of the two wires, and a connecting rod is fixed between the front sides of the two hollow columns, and a straight contact rod is fixed on the front side of the connecting rod, and the straight contact rod is located between the two side contact rods. The contacts of the two side contact rods are relatively arranged, and the front sides of the two side contact rods are not provided with contacts, and the back sides of the two side contact rods are provided with contacts. When the outer box of the meter box is dragged forward by a destroyer, the outer box of the meter box drives the side contact rods to move forward through the alarm device and the wires. At this time, the contacts of the two side contact rods will contact the straight contact rods, and the straight contact rods are connected to the two wires through the two side contact rods, and the alarm device is energized and an alarm is issued.

[0009] The U-shaped bevel rod is a vertically extending U-shaped plate, which is a vertically extending U-shaped plate. The vertically extending U-shaped plate is a vertically extending U-shaped plate. The vertically extending U-shaped plate is a vertically extending U-shaped plate. The bevel angle of the rod is located on the bevel motion trajectory of the triangular block. At the same time, when the two side contact rods drive the bevel angle of the U-shaped bevel rod to move to the bevel position of the triangular block through the U-shaped plate, the bevel angle of the triangular block pushes the bevel angle of the U-shaped bevel rod to drive the U-shaped bevel rod to move in the direction away from the center of the straight contact rod until the U-shaped bevel rod passes over the triangular block. Under the action of the spring force corresponding to the U-shaped bevel rod, the U-shaped bevel rod is reset and moves in the direction of the center of the straight contact rod. At this time, the vertical surface of the U-shaped bevel rod contacts the vertical surface of the triangular block, and the triangular block will limit the position of the U-shaped bevel rod, so that the U-shaped bevel rod limits the side contact rod to the straight contact rod.

[0010] According to the above technical solution, a locking device is provided on the front side of the hollow plug column, and the locking device includes a long slot plate, a two-way telescopic rod, two L-shaped rods, two U-shaped limit rods, and four hinged rods. The long slot plate is embedded in the lower front side of the box door, and a long slot is opened in the middle of the long slot plate. The two-way telescopic rod is fixed to the middle of the inner wall of the long slot of the long slot plate, and the two L-shaped rods are respectively fixed to the telescopic ends on both sides of the two-way telescopic rod. The two U-shaped limit rods are respectively slidably installed on both sides of the bottom of the inner wall of the outer box of the metering box. The four hinged rods are grouped in pairs, and each group of hinged rods is hinged at the outer wall of one of the hollow plug columns. The other end of each group of hinged rods is hinged to the two U The outer wall of the U-shaped limit rod, one end of the U-shaped limit rod close to the box door is located between the L-shaped rod and the long groove plate. When the thief is not familiar with the structure of the outer box of the metering box, the thief cannot open the box door only through the handle of the box door. When the staff needs to open the box door, the staff pushes the two L-shaped rods to move toward the center of the two-way telescopic rod, and the two L-shaped rods squeeze the telescopic ends on both sides of the two-way telescopic rod, and the two L-shaped rods will be staggered with the position of the U-shaped limit rod. At this time, the staff can open the box door through the handle of the box door.

[0011] According to the above technical solution, the locking device also includes two L-shaped swing rods and two hexagonal holes. The two L-shaped swing rods are rotatably installed on both sides of the long slot plate respectively. The L-shaped swing rod is located inside the outer box of the metering box, and a torsion spring is provided between the L-shaped swing rod and the rear side of the long slot plate. The two hexagonal holes are respectively opened on the front sides of the two L-shaped swing rods. When the outer box of the metering box is dragged forward by a destroyer, the outer box of the metering box drives the U-shaped limit rod to move toward the front side of the hollow column. At this time, the hinged rod pushes the U-shaped limit rod to move along the inside of the outer box of the metering box toward the direction away from the hollow column. At this time, the U-shaped limit rod moves between the L-shaped swing rod and the long slot plate, and the U-shaped limit rod will limit the position of the box door through the L-shaped swing rod.

[0012] The present invention provides an electric energy metering box with a security structure, which has the following beneficial effects:

[0013] (1) The present invention arranges an anti-sway device so that the screw, internal thread plate, hollow plug column, rotating column, triangular push plate and card plate cooperate with each other. Under the action of the spring force corresponding to the hollow plug column, the spring of the hollow plug column will push the outer box of the meter box to be close to the wall, thereby avoiding the appearance of a gap between the outer box of the meter box and the wall, thereby extending the service life of the outer box of the meter box. At the same time, the hollow plug column will limit the position of the outer box of the meter box, making it inconvenient for vandals to remove the outer box of the meter box from the wall, thereby effectively preventing the outer box of the meter box from being stolen by vandals; at the same time, the rubber ring will seal the internal space of the hollow plug column, thereby avoiding the moisture at the wall from invading the inner part of the outer box of the meter box through the through-hole of the hollow plug column, causing the moisture to corrode the electronic components inside the meter box, thereby extending the service life of the electronic components inside the outer box of the meter box.

[0014] (2) The present invention provides an anti-theft device so that the outer box of the meter box, the alarm device, the wire, the side contact rod, and the straight contact rod cooperate to drive the alarm device to be powered on and sound an alarm, thereby reminding the staff that the outer box of the meter box is at risk of being stolen, thereby improving the security performance of the meter box; at the same time, the side contact rod, the U-shaped plate, the U-shaped bevel rod, and the triangular block cooperate to drive the U-shaped bevel rod to restrict the side contact rod to the straight contact rod, thereby avoiding the problem that a thief can reset the outer box of the meter box, causing the alarm device to stop alarming.

[0015] (3) The present invention sets a locking device so that the L-shaped rod and the two-way telescopic rod cooperate to drive the two L-shaped rods to be offset from the position of the U-shaped limit rod, so that the staff can open the box door through the door handle, thereby avoiding the problem that the vandal can directly open the box door through the door handle and damage the electronic components inside the outer box of the metering box; at the same time, the outer box of the metering box, the U-shaped limit rod, the hollow plug column, the hinged rod, and the L-shaped swing rod cooperate to drive the U-shaped limit rod to limit the position of the box door through the L-shaped swing rod, thereby avoiding the problem that the vandal finds that the outer box of the metering box cannot be removed and gropes to push the two L-shaped rods to open the box door, thereby further improving the anti-theft performance of the outer box of the metering box.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

The top and bottom inclined surfaces of the triangular push plate 55 are slidably installed with a card plate 56, and the two card plates 56 respectively penetrate the top and bottom of the hollow plug column 51, and an anti-theft device 6 is arranged below the lower hollow plug column 51. Through the setting of the above structure, under the action of the spring elastic force corresponding to the hollow plug column 51, the spring of the hollow plug column 51 will push the outer box 1 of the meter box to close to the wall, thereby avoiding the appearance of a gap between the outer box 1 of the meter box and the wall, thereby extending the service life of the outer box 1 of the meter box, and at the same time, the hollow plug column 51 will limit the position of the outer box 1 of the meter box, so that it is inconvenient for a vandal to remove the outer box 1 of the meter box from the wall, thereby effectively preventing the outer box 1 of the meter box from being stolen by a vandal.

[0026] A rubber ring 57 is fixed to the outside of the rotating column 54, and the outer wall of the rubber ring 57 contacts the inner wall of the hollow column 51. The screw 53 is moved toward the inside of the hollow column 51 by the thread action of the internal threaded plate 52. Through the setting of the above structure, the rubber ring 57 can seal the internal space of the hollow column 51, thereby preventing moisture from the wall from invading the inside of the meter box outer box 1 through the through-hole of the hollow column 51, causing moisture to corrode the electronic components inside the meter box, thereby extending the service life of the electronic components inside the meter box outer box 1.

[0027] The anti-theft device 6 includes an alarm device 61, which is fixed to the bottom of the inner wall of the outer box 1 of the meter box. Wires 62 are fixed on both sides of the top of the alarm device 61, and side contact rods 63 are fixed to the top front sides of the two wires 62. A connecting rod 64 is fixed between the front sides of the two hollow plugs 51, and a straight contact rod 65 is fixed on the front side of the connecting rod 64. The straight contact rod 65 is located between the two side contact rods 63, and the contacts of the two side contact rods 63 are relatively arranged, and the front sides of the two side contact rods 63 are not provided with contacts, and the rear sides of the two side contact rods 63 are provided with contacts. Through the arrangement of the above structure, the straight contact rod 65 connects the two wires 62 through the two side contact rods 63, and the alarm device 61 is energized and an alarm is issued, thereby reminding the staff that the outer box 1 of the meter box is at risk of being stolen, thereby improving the security performance of the meter box.

[0028] The anti-theft device 6 also includes four triangular blocks 67, four U-shaped plates 66, and two U-shaped angled rods 68. The four triangular blocks 67 are respectively fixed at the four corners of the straight contact rod 65, and the four U-shaped plates 66 are respectively fixed at the top and bottom of the two side contact rods 63. Two of the four U-shaped plates 66 form a group, and the upper and lower ends of each U-shaped angled rod 68 are respectively slidably arranged in the U-shaped plates 66 located at the top and bottom of the side contact rod 63, and a spring is arranged between the U-shaped angled rod 68 and the side contact rod 63. The side away from the center of the straight contact rod 65 is set at an angle, and the side of the U-shaped bevel rod 68 close to the center of the straight contact rod 65 is set at an angle. The bevel of the U-shaped bevel rod 68 is located on the bevel movement trajectory of the triangular block 67. Through the setting of the above structure, the triangular block 67 will limit the position of the U-shaped bevel rod 68, so that the U-shaped bevel rod 68 limits the side contact rod 63 at the straight contact rod 65, thereby avoiding the problem that the vandal can reset the outer box 1 of the metering box, causing the alarm device 61 to stop alarming.

[0029] When in use, the meter box outer box 1 is installed on the wall through the I-shaped bracket 2, and then the hollow column 51 is inserted into the wall, and the screw 53 is rotated. The screw 53 is moved toward the inside of the hollow column 51 by the thread action of the internal threaded plate 52, and the screw 53 pushes the rotating column 54 and the triangular push plate 55 to move accordingly. The inclined surface of the triangular push plate 55 pushes the clamping plate 56 to move along the through-opening of the hollow column 51 in the direction away from the center of the hollow column 51, so that the clamping plate 56 clamps the hollow column 51 to the wall. When the bolts of the I-shaped bracket 2 are loosened due to long-term use due to the influence of the external environment, under the action of the spring force corresponding to the hollow column 51, the spring of the hollow column 51 will push the meter box outer box 1 to fit tightly against the wall, thereby avoiding the meter box outer box 1 and the wall, thereby extending the service life of the outer box 1 of the meter box; at the same time, the rubber ring 57 will seal the internal space of the hollow plug column 51, thereby preventing moisture at the wall from invading the outer box 1 of the meter box through the through-hole of the hollow plug column 51, causing moisture to corrode the electronic components inside the meter box, thereby extending the service life of the electronic components inside the outer box 1 of the meter box; when a vandal wants to dismantle and steal the meter box outer box 1, the vandal removes the bolts of the I-shaped bracket 2 to remove the outer box 1 of the meter box, and the hollow plug column 51 will limit the position of the outer box 1 of the meter box, making it inconvenient for the vandal to remove the outer box 1 of the meter box from the wall, thereby effectively preventing the outer box 1 of the meter box from being stolen by the vandal.

[0030] At the same time, when the outer box 1 of the meter box is dragged forward by the vandal, the outer box 1 of the meter box drives the side contact rod 63 to move forward through the alarm device 61 and the wire 62. At this time, the contacts of the two side contact rods 63 will contact the straight contact rod 65, and the straight contact rod 65 will connect the two wires 62 through the two side contact rods 63. The alarm device 61 is energized and sounds an alarm, thereby reminding the staff that the outer box 1 of the meter box is at risk of being stolen, thereby improving the security performance of the meter box; at the same time, when the two side contact rods 63 drive the oblique angle of the U-shaped bevel rod 68 to move to the oblique angle position of the triangular block 67 through the U-shaped plate 66, the oblique angle of the triangular block 67 pushes the U The oblique angle of the U-shaped bevel rod 68 drives the U-shaped bevel rod 68 to move away from the center of the straight contact rod 65 until the U-shaped bevel rod 68 passes over the triangular block 67. Under the action of the spring force corresponding to the U-shaped bevel rod 68, the U-shaped bevel rod 68 is reset and moves toward the center of the straight contact rod 65. At this time, the vertical surface of the U-shaped bevel rod 68 contacts the vertical surface of the triangular block 67. The triangular block 67 will limit the position of the U-shaped bevel rod 68, so that the U-shaped bevel rod 68 limits the side contact rod 63 at the straight contact rod 65, thereby avoiding the problem that the vandal can reset the outer box 1 of the metering box, causing the alarm device 61 to stop alarming.

[0031] See also Figure 1-7On the basis of the above embodiment, in another embodiment of the present invention, a locking device 7 is provided on the front side of the hollow plug 51 .

[0032] The locking device 7 includes a long slot plate 71, a two-way telescopic rod 72, two L-shaped rods 73, two U-shaped limiting rods 74, and four hinged rods 75.

The two-way telescopic rod 72 is fixed to the middle of the inner wall of the long slot of the long slot plate 71. The two L-shaped rods 73 are respectively fixed to the telescopic ends on both sides of the two-way telescopic rod 72. The two U-shaped limiting rods 74 are respectively slidably installed on both sides of the bottom of the inner wall of the outer box 1 of the metering box. The four hinged rods 75 are each two in a group. Each group of hinged rods 75 is hinged at the outer wall of one of the hollow plug columns 51. The other end of each group of hinged rods is hinged to two U At the outer wall of the U-shaped limit rod 74, one end of the U-shaped limit rod 74 close to the box door 4 is located between the L-shaped rod 73 and the long groove plate 71. Through the arrangement of the above-mentioned structure, the two L-shaped rods 73 will be staggered from the position of the U-shaped limit rod 74. At this time, the staff can open the box door 4 through the handle of the box door 4, thereby avoiding the problem that a vandal can directly open the box door 4 through the handle of the box door 4 and damage the electronic components inside the outer box 1 of the metering box.

[0033] The locking device 7 also includes two L-shaped swing rods 76 and two hexagonal holes 77. The two L-shaped swing rods 76 are rotatably installed on both sides of the long slot plate 71 respectively. The L-shaped swing rods 76 are located inside the outer box 1 of the meter box, and a torsion spring is provided between the L-shaped swing rod 76 and the rear side of the long slot plate 71. The two hexagonal holes 77 are respectively opened on the front sides of the two L-shaped swing rods 76. Through the arrangement of the above structure, the U-shaped limit rod 74 will limit the position of the box door 4 through the L-shaped swing rod 76, thereby avoiding the problem that the vandal finds that the outer box 1 of the meter box cannot be removed and tries to push the two L-shaped rods 73 to open the box door 4, thereby further improving the anti-theft performance of the outer box 1 of the meter box.

[0034] When in use, if the saboteur is not familiar with the structure of the outer box 1 of the meter box, the saboteur cannot open the box door 4 only by the handle of the box door 4. When the staff needs to open the box door 4, the staff pushes the two L-shaped rods 73 to move in the direction of the center of the two-way telescopic rod 72, and the two L-shaped rods 73 squeeze the telescopic ends on both sides of the two-way telescopic rod 72, and the two L-shaped rods 73 will be staggered with the position of the U-shaped limit rod 74. At this time, the staff can open the box door 4 through the handle of the box door 4, thereby avoiding the problem that the saboteur can directly open the box door 4 through the handle of the box door 4 and damage the electronic components inside the outer box 1 of the meter box; when the outer box 1 of the meter box is dragged forward by the saboteur, the outer box 1 of the meter box drives the U-shaped limit rod 74 to move toward the front side of the hollow plug column 51. At this time, the hinged rod 75 pushes the U-shaped limit rod 74 along the inside of the outer box 1 of the meter box to move away from The hollow plug column 51 moves in the direction of the hollow plug column 51. At this time, the U-shaped limit rod 74 moves between the L-shaped swing rod 76 and the long groove plate 71. The U-shaped limit rod 74 will limit the position of the box door 4 through the L-shaped swing rod 76, thereby avoiding the problem that the vandal finds that the metering box outer box 1 cannot be removed and gropes to push the two L-shaped rods 73 to open the box door 4, thereby further improving the anti-theft performance of the metering box outer box 1. When the staff needs to reset the U-shaped limit rod 74 later, the staff inserts the hexagonal wrench into the hexagonal hole 77 and then turns the hexagonal wrench. The hexagonal wrench drives the L-shaped swing rod 76 to rotate through the hexagonal hole 77, thereby separating the L-shaped swing rod 76 from the U-shaped limit rod 74. At this time, the U-shaped limit rod 74 no longer limits the position of the box door 4 through the L-shaped swing rod 76, and the staff can open the box door 4 through the handle of the box door 4.
