DETAILED DESCRIPTION
[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0027] like Figure 1 , Figure 2 and Figure 3As shown, a low-voltage three-phase inductive electric meter box includes a box body 1, a box door 4 hinged on the front side of the box body 1, a supporting assembly 2 movably connected to the middle of the rear side of the box door 4, ventilation windows are fixedly installed on the upper and lower parts of the left side of the box body 1, and an adjustable lighting assembly 3 is fixedly installed on the right side of the box body 1.
[0028] By using the support assembly 2, when the staff is repairing or inspecting the meter box, the tool box they carry can be placed on the support plate 21 rotated to a horizontal position. Secondly, when the support plate 21 is not in use, it can be fixed in a vertical direction by two fixing rods 23. By adjusting the lighting assembly 3, when the staff is repairing the meter box, according to the desired repair position, the staff can pull the plug rod 310 and rotate the winding roller 36. When the lighting lamp 34 moves to a suitable position, the elastic restoring force of the spring 312 after releasing the plug rod 310 drives the plug block 311 to move into the slot, thereby fixing the lighting lamp 34 at a specified position, thereby improving the practicality of the meter box.
[0029] like Figure 5 As shown, the supporting assembly 2 includes a supporting plate 21, the bottom of which is rotatably connected to the middle of the rear side of the box door 4, and fixed plates 22 are fixedly installed on the left and right positions of the top of the rear side of the box door 4. The two fixed plates 22 are slidably connected on the sides away from each other with fixed rods 23 that pass through the opposite sides of the two fixed plates 22. Fixed holes 24 are opened on the left and right tops of the supporting plate 21, and the opposite ends of the two fixed rods 23 are plugged into the inner walls of the two fixed holes 24.
[0030] When the supporting plate 21 is needed, it is rotated to a horizontal position and its lower end is in contact with the stop plate 27. When the supporting plate 21 is not needed, it is rotated to a vertical position. The two fixing rods 23 are slidably inserted into the corresponding fixing holes 24 to fix the supporting plate 21 to prevent the supporting plate 21 from being unstable and affecting the operation of the internal structure of the box body 1 after the box door 4 is closed.
[0031] like Figure 5 As shown, a return spring 25 is movably sleeved on one side of the outer walls of the two fixing rods 23 away from each other, one end of the two return springs 25 away from each other is fixedly connected to the side of the outer walls of the two fixing rods 23 away from each other, and the opposite end of the two return springs 25 is fixedly connected to the side of the two fixing plates 22 away from each other.
[0032] When the two fixing rods 23 are pulled, the two return springs 25 are subjected to a tensile force, and the two fixing rods 23 are disengaged from the corresponding fixing holes 24, so that the supporting plate 21 is released and can resume the rotating state. When the supporting plate 21 is subsequently rotated to its original position, after the two fixing rods 23 are loosened, the elastic restoring force of the two return springs 25 drives the two fixing rods 23 to reset and re-fix the supporting plate 21.
[0033] like Figure 5As shown, a plurality of linearly arranged limiting grooves 26 are provided on the front side of the supporting plate 21 , and a stop plate 27 is fixedly installed on the middle part of the rear side of the door 4 , and the stop plate 27 is located below the supporting plate 21 .
[0034] When the staff places the tool box on the upper end of the supporting plate 21 , the plurality of limiting grooves 26 can limit the position of the tool box to prevent the tool box from moving on the supporting plate 21 .
[0035] like Figure 4 and Figure 6 As shown, the adjustable lighting assembly 3 includes two slide rails 31, the right sides of the two slide rails 31 are fixedly installed at the front and rear positions of the right part of the inner wall of the box body 1, the inner walls of the two slide rails 31 are slidably connected with sliders 32, the left sides of the two sliders 32 are fixedly installed with a moving plate 33, and the left side of the moving plate 33 is fixedly installed with a lighting lamp 34.
[0036] The two sliders 32 are T-shaped structures, and the two slide rails 31 are provided with T-shaped grooves inside. The cooperation between the corresponding sliders 32 and the slide rails 31 can limit the movement of the movable plate 33. When the movable plate 33 moves, the lighting lamp 34 moves accordingly, so that the staff can adjust the lighting according to the specific position to be processed inside the box 1. Among them, the lighting lamp 34 is an existing structure, which is an LED lighting lamp, and its power supply structure and some wires can be installed on the movable plate 33.
[0037] like Figure 6 As shown, mounting plates 35 are fixedly installed at the front and rear positions of the right bottom of the box body 1, and adjustable winding rollers 36 are rotatably connected to the opposite sides of the two mounting plates 35. A rope 37 is wound around the middle of the outer wall of the winding roller 36. A through hole is provided at the top right side of the box body 1, and one end of the rope 37 away from the winding roller 36 is fixedly connected to the middle of the upper end of the movable plate 33, and the outer wall of the rope 37 is movably connected to the inner wall of the through hole. A guide roller 38 is rotatably connected to the top right side of the box body 1, and the bottom of the outer wall of the rope 37 overlaps the outer wall of the guide roller 38, and an observation port is provided in the middle of the right side of the box body 1.
[0038] The winding roller 36 is rotated to continuously release or retract the rope 37, and the end of the rope 37 away from the winding roller 36 drives the moving plate 33 to move, so that the moving plate 33 can drive the illuminating lamp 34 to move to a suitable position. The guide roller 38 has a limiting effect on the movement of the rope 37, and the staff can observe the moving position of the illuminating lamp 34 through the observation window.
[0039] like Figure 7As shown, a mounting frame 39 is fixedly installed on the right rear side of the rear mounting plate 35, and a plug rod 310 that passes through the rear of the mounting frame 39 is slidably connected to the rear side of the mounting frame 39, and a plug block 311 is fixedly installed on the front end of the plug rod 310, and slots are provided on the winding roller 36 and the rear side of the rear mounting plate 35, and the front end of the plug block 311 is plugged into the inner wall of the slot.
[0040] By moving the insertion rod 310, the insertion rod 310 drives the insertion block 311 to be inserted into the slot or to be separated from the slot, so that the winding roller 36 is fixed or released.
[0041] like Figure 7 As shown, a spring 312 is movably sleeved on the front of the outer wall of the insertion rod 310 , the front end of the spring 312 is fixedly connected to the rear side of the insertion block 311 , and the rear end of the spring 312 is fixedly connected to the rear of the inner wall of the mounting frame 39 .
[0042] By pulling or releasing the insertion rod 310, when the insertion rod 310 is pulled, the spring 312 is squeezed and accumulates elastic potential energy, and the plug block 311 moves backward with the insertion rod 310 and disengages from the slot, so that the winding roller 36 can rotate. After the insertion rod 310 is released, the elastic potential energy of the spring 312 is released to drive the plug block 311 and the insertion rod 310 to reset and quickly fix the winding roller 36.
[0043] The working principle of the utility model is as follows: when the staff is handling the internal structure of the meter box, they open the box door 4, close the meter box, make the box door 4 at a certain angle, pull the two fixing rods 23, and make the two fixing rods 23 disengage from the two fixing holes 24 at the same time. At this time, the two return springs 25 are stretched by force, the support plate 21 is released and rotated to the horizontal, the lower end of the support plate 21 contacts the stop plate 27 and is restricted from rotating, and the staff places the tools used for maintenance or detection on the support plate 21.
[0044] If the staff turns on the lighting 34 at night or when the light is dim, the staff will pull the insertion rod 310 through the position to be repaired inside the box 1, so that the insertion rod 310 drives the insertion block 311 to disengage from the slot. At this time, the spring 312 is subjected to the squeezing force, and then the winding roller 36 is rotated to make the rope 37 be evenly released or retracted. The end of the rope 37 away from the winding roller 36 pulls or loosens the movable plate 33, so that the movable plate 33 slides on the two slide rails 31 through the two sliders 32 and moves. Observe through the observation port. When the lighting 34 moves to the specified position, stop rotating the winding roller 36, loosen the insertion rod 310, and the elastic restoring force of the spring 312 drives the insertion rod 310 and the insertion block 311 to reset, and the insertion block 311 is reinserted into the slot, so that the winding roller 36 can be fixed to ensure the stability of the lighting 34.
[0045] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
