[0027] like Figure 1 and Figure 2As shown, the positioning mechanism 2 includes a U-shaped limiting plate 201 and two groups of fixed blocks 207, the U-shaped limiting plate 201 is installed on the front of the back plate 3, and the inner walls on the left and right sides of the U-shaped limiting plate 201 are provided with card grooves, and the two groups of card grooves of the U-shaped limiting plate 201 are slidably connected with sliders 202, and a fixing plate 203 is installed between the adjacent sides of the two groups of sliders 202, and a connecting plate 204 is installed on the front of the fixing plate 203. The upper surface of the connecting plate 204 is provided with a card groove, and the card groove of the connecting plate 204 is slidably connected with an L-shaped limiting plate 205, and the front of the L-shaped limiting plate 205 is installed on the back of the distribution box 1, and two groups of card blocks 206 are installed on the back of the fixing plate 203. The two groups of fixed blocks 207 are both installed on the front of the back plate 3, and the front of the two groups of fixed blocks 207 are provided with grooves, and the positions of the grooves inside the two groups of fixed blocks 207 are respectively located on the moving paths of the two groups of card blocks 206;

[0028] Specifically, when the staff is installing the distribution box 1, they pull the fixing plate 203 to move the connection plate 204 out of the U-shaped limiting plate 201, and then move the distribution box 1 to insert the L-shaped limiting plate 205 into the card slot of the connecting plate 204, so that the distribution box 1 is installed to the front of the fixing plate 203, and push the distribution box 1 to drive the fixing plate 203 to reset, and install the distribution box 1 to the front end of the back plate 3, so as to complete the installation of the distribution box 1;

[0029] At the same time, after the back plate 3 is installed on the inner wall of the electric shaft, the two groups of sliders 202 are driven to move inside the two groups of slots of the U-shaped limit plate 201 by pulling the fixed plate 203, so that the position of the front installation space of the connecting plate 204 can be adjusted and moved, so that the staff can pull the connecting plate 204 out of the electric shaft during the installation of the distribution box 1, thereby expanding the space when the distribution box 1 is installed and fixed at the front end of the back plate 3, thereby reducing the time and labor spent by the staff in installing and disassembling the distribution box 1, thereby improving the practicality of the device.

[0030] like Figure 2 As shown, a spring telescopic rod 7 is installed on the front of the back plate 3, and the front of the spring telescopic rod 7 is installed on the back of the fixed plate 203; specifically, when the staff installs the distribution box 1 on the front side of the fixed plate 203, the spring telescopic rod 7 uses its own elastic potential energy to pull the fixed plate 203 to automatically reset, so that the staff does not need to manually adjust the position of the mobile distribution box 1 during the installation and positioning of the distribution box 1, thereby reducing the labor consumed by subsequent staff when installing the distribution box 1.

[0031] like Figure 3As shown, the inner walls of the back sides of the two groups of fixed blocks 207 are both installed with magnetic blocks 6, and the two groups of magnetic blocks 6 are respectively adsorbed on the back sides of the two groups of clamping blocks 206; specifically, when the distribution box 1 is installed on the front side of the positioning mechanism 2, the back sides of the two groups of clamping blocks 206 are adsorbed on the front sides of the two groups of magnetic blocks 6 by pushing the fixed plate 203, so that the two groups of magnetic blocks 6 limit the moving position of the fixed plate 203 inside the U-shaped limiting plate 201, thereby avoiding movement of the distribution box 1 when it is installed to the front end of the back plate 3 as much as possible, thereby improving the stability of the distribution box 1 during use after installation.

[0032] like Figure 1 and Figure 2 As shown, a bottom plate 4 is installed on the lower surface of the back plate 3, and the upper surface of the bottom plate 4 abuts against the lower surfaces of the distribution box 1 and the U-shaped limit plate 201; specifically, the upper surface of the bottom plate 4 is attached to the lower surface of the distribution box 1, so that the bottom plate 4 supports the distribution box 1 when the distribution box 1 is installed to the front of the back plate 3, thereby avoiding bending at the connection between the distribution box 1 and the positioning mechanism 2 when the mass of the distribution box 1 is too large; the lower surface of the bottom plate 4 abuts against the lower surface of the U-shaped limit plate 201, so that the U-shaped limit plate 201 and the bottom plate 4 form a group of rectangular frames during use, and then the bottom plate 4 and the U-shaped limit plate 201 shield and protect the equipment between the distribution box 1 and the back plate 3, thereby avoiding damage to the equipment between the distribution box 1 and the back plate 3 during daily use.

[0033] like Figure 1 and Figure 4 As shown, the limiting mechanism 5 includes a limiting plate 501, a fixing plate 203 and the upper surface of the U-shaped limiting plate 201 are provided with a card slot, the limiting plate 501 is slidably connected inside the card slot of the U-shaped limiting plate 201, the position of the card slot inside the fixing plate 203 is located on the moving path of the limiting plate 501, a U-shaped fixing block 502 is provided on one side of the limiting plate 501, a groove is provided on the front inner wall of the U-shaped fixing block 502, the groove of the U-shaped fixing block 502 is rotatably connected to the limiting rod 503, and the lower surface of the limiting rod 503 abuts against the upper surface of the U-shaped limiting plate 201;

[0034] Specifically, when the staff is installing the distribution box 1, they pull the fixing plate 203 to drive the connecting plate 204 to move away from the lower end of the U-shaped limiting plate 201, and then push the limiting plate 501 to insert the lower end of the limiting plate 501 into the slot of the fixing plate 203, so that the limiting mechanism 5 limits the position of the positioning mechanism 2 when the staff is installing the distribution box 1, and thus the staff does not need to manually limit the position of the fixing plate 203 inside the U-shaped limiting plate 201 during the installation of the distribution box 1, thereby reducing the labor consumed by the subsequent staff when installing the distribution box 1;

[0035] At the same time, when the spring telescopic rod 7 pulls the fixed plate 203 to reset, the limit plate 501 is pulled to partially move the limit plate 501 to the upper end of the U-shaped limit plate 201, and then the limit rod 503 is rotated to make the lower surface of the limit rod 503 abut against the upper surface of the U-shaped limit plate 201, so that the limit rod 503 limits the moving position of the limit plate 501 inside the slot of the U-shaped limit plate 201, thereby avoiding as much as possible that the subsequent limit mechanism 5 blocks the normal movement of the fixed plate 203 during the idle process.

[0036] In summary: by pulling the fixed plate 203, the position of the connecting plate 204 is moved out of the interior of the U-shaped limit plate 201, and then by moving the distribution box 1, the L-shaped limit plate 205 is plugged into the slot of the connecting plate 204, so that the distribution box 1 is installed to the front of the fixed plate 203, and the fixed plate 203 is reset by pushing the distribution box 1, and the distribution box 1 is installed and positioned to the front end of the back plate 3, thereby completing the installation of the distribution box 1; by pulling the fixed plate 203, the two groups of sliders 202 are driven to move inside the two groups of slots of the U-shaped limit plate 201, so that the position of the installation space on the front side of the connecting plate 204 can be adjusted and moved, so that the staff can pull the connecting plate 204 out of the interior of the electric well during the installation of the distribution box 1, thereby expanding the space when the distribution box 1 is installed and fixed at the front end of the back plate 3, thereby reducing the time and labor consumed by the staff when installing and disassembling the distribution box 1.

[0037] At the same time, by pulling the fixed plate 203, the connecting plate 204 is moved away from the lower end of the U-shaped limit plate 201, and then by pushing the limit plate 501, the lower end of the limit plate 501 is inserted into the slot of the fixed plate 203, so that the limit mechanism 5 limits the position of the positioning mechanism 2 when the staff installs the distribution box 1, so that the staff does not need to manually limit the position of the fixed plate 203 inside the U-shaped limit plate 201 during the installation of the distribution box 1, thereby reducing the labor consumed by subsequent staff when installing the distribution box 1.
