[0029] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-4 This utility model provides an embodiment of a building low-voltage electrical control box, including a low-voltage box 1. The low-voltage box 1 has no front side wall. A door 11 is hinged to the front of the left side wall of the low-voltage box 1. A rotary latch 12 is installed on the side of the door 11 away from the low-voltage box 1. A stop block adapted to the rotary latch 12 is fixed to the front of the right inner side wall of the low-voltage box 1 to facilitate locking the door 11 after closing. Horizontal screws 2 are rotatably connected to the rear of the inner side walls on both sides of the low-voltage box 1 through bearings. The top of the screws 2... A vertical handle 3 is fixed in the middle. Rear blocks 6 are slidably installed on both sides of the inner rear wall of the low-voltage box 1. The two rear blocks 6 are respectively threaded onto both sides of the outer ring of the screw 2. Guide holes 15 are opened on both sides of the side wall of the low-voltage box 1. Horizontal fixed columns 7 are fixed at the far ends of the two rear blocks 6. Slide rail blocks 5 are fixed on both sides of the inner rear wall of the low-voltage box 1. A slider 18 is fixed at the top of the rear block 6. The slider 18 is slidably connected to the slide rail block 5, so that the rear blocks 6 and the fixed columns 7 can move horizontally stably.

[0031] The fixed column 7 is movably inserted into the guide hole 15. The two fixed columns 7 are movably fitted with side embedded sleeves 8 on the parts extending out of the weak current box 1. Vertical sleeves 16 are fixed on both sides of the bottom wall of the weak current box 1. Bottom columns 17 are movably inserted into the inner ring of the sleeves 16. The tops of the two bottom columns 17 are respectively hinged to the bottom ends of the two rear blocks 6 with a pair of shafts 9. The bottom of the bottom column 17 extends out of the weak current box 1 and is movably fitted with bottom embedded sleeves 10. A wall hole is opened in the wall of the building. The size of the wall hole is adapted to the size of the weak current box 1. The two side embedded sleeves 8 are respectively embedded in the inner side walls on both sides of the wall hole. The two bottom embedded sleeves 10 are respectively embedded in the inner bottom wall on both sides of the wall hole.

[0032] Reference Figure 1 Both sides of the inner top wall of the low-voltage box 1 located in front of the rear block 6 are fixed with a control frame 13. The bottom end of the control frame 13 is fixed to the inner bottom wall of the low-voltage box 1. Multiple threaded holes are opened on the control frame 13 from top to bottom. The low-voltage equipment can be fixed on the control frame 13 with bolts. Multiple through holes 14 are opened in the horizontal direction on the bottom wall of the low-voltage box 1 to facilitate the passing of low-voltage cables through the through holes 14.

[0033] Reference Figure 1 and Figure 2The top of the handle 3 is threaded with a fixed screw 4. The top of the handle 3 is fixed to the inner wall of the rear end of the low-voltage box 1 by the fixed screw 4. This can prevent the handle 3 and the screw 2 from rotating accidentally, and can prevent the rear block 6, the fixed column 7 and the bottom column 17 from moving accidentally. The outer ring of the handle 3 is provided with friction texture to prevent the handle 3 from slipping out of the hand when it is turned.

[0034] Reference Figure 1 and Figure 2 The threads on both sides of the outer ring of the screw 2 turn in opposite directions, and the two pairs of shafts 9 are symmetrically arranged in a figure-eight shape. When the handle 3 is turned down, the screw 2 can be rotated clockwise. Through the threaded transmission between the screw 2 and the two rear blocks 6, the two rear blocks 6 can drive the tops of the two pairs of shafts 9 to move closer to each other, and the bottoms of the two pairs of shafts 9 can drive the two bottom columns 17 to rise. When the handle 3 is turned up, the screw 2 can be rotated counterclockwise, and the two rear blocks 6 can drive the tops of the two pairs of shafts 9 to move away from each other, and the bottoms of the two pairs of shafts 9 can drive the two bottom columns 17 to fall.

[0035] Reference Figures 1-3 The inner ring of the upright sleeve 16 is square, and the size of the inner ring of the upright sleeve 16 is adapted to the size of the base column 17, so that the base column 17 can be raised and lowered stably. The bottom end of the upright sleeve 16 is flush with the outer bottom wall of the weak current box 1. The inner ring of the bottom embedded sleeve 10 is adapted to the size of the base column 17. The top end of the bottom embedded sleeve 10 is in contact with the outer bottom wall of the weak current box 1. The two bottom embedded sleeves 10 are respectively embedded on both sides of the inner bottom wall of the wall hole. When the two base columns 17 are respectively inserted into the two bottom embedded sleeves 10, the weak current box 1 can be prevented from shifting.

[0036] The size of the guide hole 15 is adapted to the size of the fixed column 7, and the size of the inner ring of the side embedded sleeve 8 is adapted to the size of the fixed column 7. The side ends of the two side embedded sleeves 8 that are close to each other contact the outer side walls of the two sides of the weak current box 1 respectively. The two side embedded sleeves 8 are respectively embedded in the inner side walls of the two sides of the wall hole. When the two fixed columns 7 are respectively inserted into the interior of the two side embedded sleeves 8, the weak current box 1 can be further prevented from shifting, and the weak current box 1 can be firmly fixed.

[0037] Working principle: If a low-voltage control box needs to be installed during building construction, a wall opening is made in the building wall, the size of which matches the size of the low-voltage box 1. Two side embedded sleeves 8 are respectively embedded in the inner side walls of the wall opening on both sides, and two bottom embedded sleeves 10 are respectively embedded in the inner bottom wall of the wall opening on both sides. Then, remove the fixing screw 4 and turn the handle 3 downwards, which can drive the screw 2 to rotate clockwise. Through the threaded transmission between the screw 2 and the two rear blocks 6, the two rear blocks 6 can drive the two fixed columns 7 to move closer to each other, which can drive the top ends of the two opposing shafts 9 to move closer to each other, which can drive the bottom ends of the two opposing shafts 9 to move the two bottom columns 17 upwards until the side ends of the two sliders 18 contact the inner side walls of the two sliding rail blocks 5 that are close to each other. At this time, the side ends of the fixed columns 7 are located inside the guide holes 15, and the bottom ends of the bottom columns 17 are located at the vertical position. Inside the sleeve 16, the low-voltage box 1 is then placed inside the wall hole, allowing the inside of the side embedded sleeve 8 to connect with the guide hole 15 and the inside of the bottom embedded sleeve 10 to connect with the inside of the vertical sleeve 16. Then, the handle 3 is turned upwards, which causes the screw 2 to rotate counterclockwise, causing the two rear blocks 6 to move away from the two fixed posts 7, and the top ends of the two opposing shafts 9 to move away from each other, causing the bottom ends of the two opposing shafts 9 to lower the two bottom posts 17 until the two fixed posts 7 are inserted into the inside of the two side embedded sleeves 8 and the two bottom posts 17 are inserted into the inside of the two bottom embedded sleeves 10, thus firmly fixing the low-voltage box 1. Then, the handle 3 is fixed with the fixing screw 4, and the installation of the low-voltage control box is completed. The installation of the low-voltage control box does not require many screws for fixing, and the process of installing the low-voltage control box is relatively simple.

[0038] If it is necessary to disassemble the low-voltage control box, remove the set screw 4, and turn the handle 3 downwards to drive the screw 2 to rotate clockwise. Through the threaded transmission between the screw 2 and the two rear blocks 6, the two rear blocks 6 can drive the two fixed columns 7 to move closer to each other, which can cause the bottom ends of the two opposing shafts 9 to drive the two bottom columns 17 to rise until the side ends of the fixed columns 7 are inside the guide holes 15, which can cause the fixed columns 7 to disengage from the side embedded sleeves 8. The bottom ends of the bottom columns 17 are inside the upright sleeves 16, which can cause the bottom columns 17 to disengage from the upright sleeves 16. Then, by pulling the control frame 13, the low-voltage box 1 can be moved until the low-voltage box 1 is disengaged from the wall hole, thus completing the disassembly of the low-voltage control box. When disassembling the low-voltage control box, it is not necessary to remove a large number of screws one by one, which facilitates the inspection and maintenance of the internal equipment of the low-voltage control box.

[0039] Finally, it should be noted that in the description of this utility model, the terms "vertical," "upper," "lower," "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
