[0002] The purpose of the meter box is to centrally install and protect electricity meters, and to realize safe electricity management and metering data collection. In the existing technology, the meter box support structure includes a main fixing plate and two auxiliary fixing plates located on the sides of the main fixing plate. The main fixing plate and the two auxiliary fixing plates are connected by a connecting rod to drive the movement of the auxiliary fixing plates. However, the auxiliary fixing plates need to be moved manually during the movement. As a result, the distance between the auxiliary fixing plates on both sides and the main fixing plate can only be observed by the operator's naked eye. This can lead to the meter box being unstable when it is placed because the distance between the auxiliary fixing plates is too large or too small. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defect in the prior art that the distance between the main fixing plate and the auxiliary fixing plate cannot be precisely adjusted, resulting in unstable placement of the watch box, thereby providing a watch box support structure with good stability and adjustable size.

[0004] Therefore, this utility model provides an adjustable-size watch box support structure, including a central column and side columns disposed on both sides of the central column. A moving mechanism is provided between the central column and the side columns to assist the side columns in moving away from or closer to the central column. A first moving plate is disposed on the central column. A moving device is provided between the central column and the first moving plate to assist the first moving plate in moving along the height direction of the central column. The moving device includes a screw fixed to one side of the central column and a nut fixed to one side of the first moving plate. The screw passes through the nut and is threadedly connected to the nut. A rotating block for driving the screw to rotate is fixedly disposed on the top of the screw.

[0005] Furthermore: a second positioning plate is also provided on the central column, and the moving mechanism includes a first connecting rod and a second connecting rod. The first moving plate and / or the second positioning plate are threadedly connected to the screw. One end of the first connecting rod and the second connecting rod are respectively hinged to the first moving plate and the second positioning plate, and the other end is hinged to the first connecting rod and the second connecting rod. The first connecting rod or the second connecting rod is hinged to the side column.

[0006] Furthermore: the first movable plate is threadedly connected to the screw rod, the second positioning plate is fixedly mounted on the central column, the second connecting rod is hinged to the side column, the first connecting rod is hinged to the second connecting rod, a third positioning plate is also provided on the central column, a third connecting rod is provided between the third positioning plate and the side column, one end of the third connecting rod is hinged to the third positioning plate, and the other end is hinged to the side column.

[0007] Furthermore: the central column is provided with an extension plate, the extension plate is provided with a through hole for the screw to pass through, and the central column is also provided with an extension piece for the positioning screw, the screw can pass through the through hole and extend to the end of the extension piece.

[0008] Furthermore, the side of the side column is provided with a connecting lug for connecting to the meter box.

[0009] Furthermore: a leg is hinged at the bottom of the side column, the leg can be flipped along the hinge point, and the leg has a use position for supporting the watch case and a storage position for flipping to the side of the side column.

[0010] Furthermore, a support base is provided below the central column.

[0011] Furthermore, the central column is provided with at least one bracket lug that can be connected to the wall.

[0012] Furthermore: at least one metal clamp is provided on the central column, the metal clamp can be connected to the utility pole, and the metal clamp is connected to the bracket lug by fasteners.

[0013] The technical solution of this utility model has the following advantages:

[0014] 1. This utility model provides an adjustable-size watch box support structure. To assist the first moving plate in accurately moving along the height direction of the central column, thereby controlling the distance between the two side columns, a screw is provided on the central column. The screw has an external thread, passes through the first moving plate, and a nut adapted to the screw is welded to the inner side of the first moving plate. The nut has an internal thread adapted to the screw. A rotating block is formed at the top of the screw. When it is necessary to adjust the distance between the side columns, only an external tool is needed to turn the rotating block. The rotation of the rotating block drives the screw to rotate, and the thread on the screw will engage with the screw. The relative rotation of the nut, as it rises or falls, causes the first moving plate to move up and down. After the first moving plate moves up and down, it drives the side column to move left and right through the moving mechanism. Since the distance the first moving plate moves up and down is fixed by the rotation of the screw, the swing angle of the moving mechanism is also fixed, and thus the distance the side column moves left and right is also fixed. Therefore, the distance the side column moves can be precisely controlled by the number of rotations of the rotating block. This is superior to existing technologies, as it no longer relies solely on visual observation of the side column's movement distance, but rather on precise control through the number of rotations of the screw, thus better adapting to watch cases of different sizes.

[0015] 2. This utility model provides an adjustable-size watch box support structure, in which a second positioning plate is also provided on the central column. The moving mechanism includes a first connecting rod and a second connecting rod. The second positioning plate is fixedly mounted on the central column, and the first moving plate is rotatably mounted on the central column. When it is necessary to adjust the position between the two side columns, it is only necessary to drive the first moving plate to move along the upper or lower end of the central column. The first connecting rod rotates along the hinge point with the first moving plate. Since the second connecting rod and the first connecting rod are hinged, the movement of the first connecting rod can drive the rotation of the second connecting rod, thereby controlling the angle between the first connecting rod and the second connecting rod. When the angle between the first connecting rod and the second connecting rod is larger, the distance between the two side columns is smaller, and vice versa. Furthermore, the first connecting rod and the second connecting rod are set between the central column and the two side columns, forming a triangular structure with the central column. The first connecting rod and the second connecting rod are set on both sides of the central column, making the side columns on both sides more stable during movement and when supporting the watch box, thereby avoiding safety hazards.

[0027] Example

[0028] This embodiment provides an adjustable-size watch box support structure, including a central column 1 and side columns 2 disposed on both sides of the central column 1. A moving mechanism 3 is provided between the central column 1 and the side columns 2 to assist the side columns 2 in moving away from or closer to the central column 1. A first moving plate 31 is disposed on the central column 1. A moving device 5 is provided between the central column 1 and the first moving plate 31 to assist the first moving plate 31 in moving along the height direction of the central column 1. The moving device 5 includes a screw 51 fixed to one side of the central column 1 and a nut 42 fixed to one side of the first moving plate 31. The screw 51 passes through the nut 42 and is threadedly connected to the nut 42. A rotating block 43 for driving the screw 51 to rotate is fixedly disposed on the top of the screw 51.

[0029] The specific improvements mentioned above are as follows: Figure 4As shown, to assist the first movable plate 31 in accurately moving along the height direction of the central column 1, thereby controlling the distance between the two side columns 2, a screw 51 is provided on the central column 1. The screw 51 has an external thread. The screw 51 passes through the first movable plate 31, and a nut 42 adapted to the screw 51 is welded to the first movable plate 31 (the nut 42 can be located on the inner side or top of the first movable plate 31). Preferably, the nut 42 can be located on the inner side of the first movable plate 31. The nut 42 has an internal thread adapted to the screw 51. A rotating block 43 is formed on the top of the screw 51. When it is necessary to adjust the distance between the side columns 2, only... External tools are needed to turn the rotating block 43. The rotation of the rotating block 43 drives the screw 51 to rotate. The thread on the screw 51 will rotate relative to the nut 42. The nut 42 rising or falling will drive the first moving plate 31 to move up and down. After the first moving plate 31 moves up and down, it will drive the side column 2 to move left and right through the moving mechanism 3. Since the distance that the first moving plate 31 moves up and down is fixed when the screw 51 rotates one revolution, the swing angle of the moving mechanism is also fixed. Therefore, the distance that the side column 2 moves left and right is also fixed. Thus, the distance that the side column 2 moves can be precisely controlled by the number of revolutions of the rotating block 43, so as to adapt to watch cases of different sizes.

[0030] Based on the above embodiments: a second positioning plate 32 is also provided on the central column 1, and the moving mechanism 3 includes a first connecting rod 33 and a second connecting rod 34. The first moving plate 31 and / or the second positioning plate 32 are threadedly connected to the screw 51. One end of the first connecting rod 33 and the second connecting rod 34 are respectively hinged to the first moving plate 31 and the second positioning plate 32, and the other end is hinged to the first connecting rod 33 and the second connecting rod. The first connecting rod 33 or the second connecting rod 34 is hinged to the side column 2.

[0031] The specific improvements mentioned above are as follows: Figure 1 and Figure 2As shown, two side posts 2 are set on both sides of the central column 1. The distance between the two side posts 2 and the central column 1 is adjusted by a moving mechanism 3. The moving mechanism 3 includes a first connecting rod 33 and a second connecting rod 34. A second positioning plate 32 is fixedly mounted on the central column 1, and a first moving plate 31 is rotatably mounted on the central column 1. When it is necessary to adjust the position between the two side posts 2, it is only necessary to drive the first moving plate 31 to move along the upper or lower end of the central column 1. The first connecting rod 33 rotates along the hinge point with the first moving plate 31. Since the second connecting rod 34 is hinged to the first connecting rod 33, the movement of the first connecting rod 33 can drive the second connecting rod 34 to rotate, thereby controlling the first... The angle between the first connecting rod 33 and the second connecting rod 34 is such that the larger the angle between the first connecting rod 33 and the second connecting rod 34, the smaller the distance between the two side posts 21; conversely, the smaller the angle between the first connecting rod 33 and the second connecting rod 34, the larger the distance between the two side posts 21. The first connecting rod 33 and the second connecting rod 34 are set between the central post 1 and the two side posts 2, forming a triangular structure with the central post 1. The first connecting rod 33 and the second connecting rod 34 are set on both sides of the central post 1, making the side posts 2 on both sides more stable during movement and when supporting the meter box, thereby avoiding safety hazards.

[0032] Based on the above embodiments: the first movable plate 31 is threadedly connected to the screw 51, the second positioning plate 32 is fixedly mounted on the central column 1, the second connecting rod 34 is hinged to the side column 2, the first connecting rod 33 is hinged to the second connecting rod 34, the central column 1 is also provided with a third positioning plate 4, the third positioning plate 4 and the side column 2 are provided with a third connecting rod 41, one end of the third connecting rod 41 is hinged to the third positioning plate 4, and the other end is hinged to the side column 2.

[0033] The specific improvements mentioned above are as follows: Figures 1-3 As shown, a third positioning plate 4 is provided at the bottom of the central column 1. The third positioning plate 4 and the side column 2 are connected by a third connecting rod 41. When the first connecting rod 33 and the second connecting rod 34 drive the side column 2 to move to both sides, the third connecting rod 41 can assist the lower end of the side column 2 to move. Based on the first connecting rod 33 and the second connecting rod 34, the stability of the side column 2 during movement and use is further improved.

[0034] Based on the above embodiments: an extension plate 11 is provided on the central column 1, and a through hole 12 is provided on the extension plate 11 for the screw 51 to pass through. An extension piece 10 for the positioning screw 51 is also provided on the central column 1. The screw 51 can pass through the through hole 12 and extend to the end of the extension piece 10.

[0035] The specific improvements mentioned above are as follows: an extension plate 11 extends from the side of the central column 1, and a through hole 12 is opened on the extension plate 11 for the screw 51 to pass through. A rotating block 43 is fixedly installed above the screw 51, and the lower end of the screw 51 passes through the extension piece 10. By setting the rotating block 43, not only can the screw 51 be driven to rotate, but the screw 51 can also be prevented from coming out of the through hole 12 and the extension piece 10.
