[0003] A search revealed Chinese patent publication number CN221305309U, which discloses a fixing assembly for an electricity meter box. The assembly comprises a support plate connected to the outside world, a slide slot formed on the support plate, and two threaded rods with opposite threads rotatably disposed within the slide slot. The two rods each have a mounting portion at one end facing away from each other, a retraction assembly disposed between the two rods, and matching threaded sleeves sleeved on each rod, each with a fixing portion disposed on the threaded sleeve. The fixing portion houses the electricity meter box. This device not only facilitates installation and removal of the electricity meter box, but also facilitates the replacement of the threaded rods, improving replacement efficiency and enabling the meter box to be quickly put into service.

The positioning mechanism 3 includes a top plate 301, a guide rod 308 is fixedly connected to the inner wall of the top plate 301, the top plate 30 is capable of supporting the guide rod 308, and a chute is opened on the outer wall of the top plate 301. The chute and the guide rod 308 both play a guiding role. A rotating seat 302 is rotatably connected to the center of the top plate 301. The overall shape of the rotating seat 302 is I-shaped, and the I-shaped setting can prevent the rotating seat 302 from falling. The bottom ends of the left and right sides of the rotating seat 302 are both rotatably connected with connecting plates 307. One end of the connecting plate 307 away from the top plate 301 is rotatably connected with a movable seat 304. The upper half of the connecting plate 307 is L-shaped, and the rotation of the rotating seat 302 causes the two connecting plates 307 to rotate, so that the two movable seats 304 will move towards the middle. A bottom plate 305 is slidably connected to the inner wall of the front end of the mounting plate 1, and a spherical ball 306 is rotatably connected to the top end of the bottom plate 305. The setting of the spherical ball 306 can reduce the friction of the electric energy meter box 2.

The bottom end of the fixed seat 303 is fixedly connected to the top end of the mounting plate 1. The mounting plate 1 can support the fixed seat 303. The inner wall of the fixed seat 303 is elastically connected with a latch 310 through a connecting spring 309. The latch 310 penetrates the inner wall of the fixed seat 303. Multiple insertion holes are provided at the top end of the rotating seat 302. The bottom end of the latch 310 is inserted into the inner wall of the insertion hole.

The sliding setting enables the movable seat 304 to only move horizontally closer or horizontally expand, so as to achieve the positioning effect. The bottom end of the power metering box 2 contacts the top end of the spherical ball 306. The contact between the two enables the power metering box 2 to move when it is not clamped and fixed, so as to make adjustments. The top end of the power metering box 2 contacts the bottom end of the top plate 301. The contact between the two can fix the power metering box 2. One side of the movable seat 304 close to the rotating seat 302 contacts the outer wall of the power metering box 2. The contact between the two can position the power metering box 2. The rear end of the top plate 301 is in a T shape, and the rear end of the top plate 301 is slidably connected to the inner wall of the front end of the mounting plate 1. The T-shaped setting prevents the top plate 301 from falling, and the rear end of the bottom plate 305 is also in a T shape.

[0036] Refer to Figure 4 - Figure 5, the clamping mechanism 4 includes a limit plate 401, the outer wall of the limit plate 401 is fixedly connected to the outer wall of the mounting plate 1, there are two groups of limit plates 401, a moving seat 402 is slidably connected to the inner wall of the limit plate 401, and the power metering box 2 can be clamped and fixed by the movement of the moving seat 402. One end of the moving seat 402 away from the mounting plate 1 is fixedly connected with a positioning block 405, and a bolt 404 is threadedly connected to the inner wall of the positioning block 405. The positioning block 405 can support and accommodate the bolt 404, and the bolt 404 plays a limiting role. The bottom end of the bolt 404 is threadedly connected to the inner wall of the limit plate 401. Multiple screw holes are opened on the outer wall of the limit plate 401, and the threads are threadedly connected to the bolt 404. Connecting plates 403 are rotatably connected to both the upper and lower ends of the moving seat 402. By the movement of the moving seat 402, the two connecting plates 403 can be driven to rotate, so as to achieve the clamping purpose. The top end of the upper connecting plate 403 is rotatably connected to the outer wall of the top plate 301, and the bottom end of the lower connecting plate 403 is rotatably connected to the outer wall of the bottom plate 305. The rotational setting enables the movement of the moving seat 402 to drive the top plate 301 and the bottom plate 305 to move in the vertical direction.

[0037] Working principle: When installing the power metering box 2, first place the bottom end of the power metering box 2 above the bottom plate 305, and the rear end of the power metering box 2 is in contact with the front end of the mounting plate 1. Then move the bolt 310 upward to release the limit of the bolt 310 on the rotating seat 302, and then rotate the rotating seat 302 so that the rotating seat 302 drives the two connecting plates 307 to rotate, so that the two movable seats 304 move closer to the middle. At this time, the lower parts of the two movable seats 304 are in contact with both sides of the top end of the power metering box 2, so that the power metering box 2 is in the middle position of the mounting plate 1. After the adjustment is completed, release the bolt 310. At this time, due to the elasticity of the connecting spring 309, the bolt 310 resets and is inserted and fixed with the rotating seat 302, so as to achieve the purpose of rapid positioning.

[0038] After the positioning operation is adjusted, at this time, rotate the bolt 404 to release the limit of the bolt 404 on the limit plate 401, and then the moving seat 402 can be moved backward to make the two connecting plates 403 move, and then the top plate 301 and the bottom plate 305 move closer, so that the power metering box 2 can be clamped and fixed. After fixing, rotate the bolt 404 in the reverse direction to complete the limit. The operation is simple and convenient.
