[0034] Reference Figure 1 、 Figure 5 and Figure 6 The locating plate 36 is fixedly connected to the inner wall of the mounting frame 1, and the inner wall of the locating plate 36 passes through and is fixedly connected to the mounting block 37. The mounting block 37 is a hollow rectangular parallelepiped, and the inner wall of the mounting block 37 is slidably connected to the positioning rod 38. The bottom end of the positioning rod 38 is set to be spherical, and the bottom end of the positioning rod 38 is set to be rigid material. The outer wall of the positioning rod 38 is fixedly connected to a positioning ring 39. The inner wall material of the positioning ring 39 is set to rubber. By setting the material, it is ensured that after the positioning ring 39 fits the surface of the positioning rod 38, there is sufficient friction between the positioning ring 39 and the positioning rod 38, thereby ensuring that the positioning rod 38 cannot move. The bottom end of the positioning ring 39 is elastically connected to the inner wall of the mounting block 37 by a tension spring 310. One end of the tension spring 310 is fixedly connected to the bottom end of the positioning ring 39, and the other end of the tension spring 310 is fixedly connected to the inner wall of the mounting block 37. The elastic force of the tension spring 310 and the gravity of the mounting plate 35 and the buoyancy block 33 are less than the buoyancy of the suspension.

[0035] Reference Figure 4-Figure 6 The interior of the mounting frame 1 is provided with a fixing assembly 4, which includes a fixing plate 41. The outer wall of the fixing plate 41 is slidably connected to the inner wall of the mounting frame 1. The inner wall of the fixing plate 41 is penetrated by a screw 42. The screw 42 is used to fix the mounting frame 1 to the distribution box. The outer wall of the screw 42 penetrates and is threadedly connected to the inner wall of the mounting frame 1. The front end of the screw 42 is provided with a groove that allows the staff to easily rotate the screw 42 through other tools. The outer wall of the screw 42 is fixedly connected with a push plate 43. The rear end of the push plate 43 is rotatably connected to the front end of the fixing plate 41. The fixing plate The inner wall of 41 is provided with a hole with a diameter larger than the diameter of the screw 42 but smaller than the outer diameter of the push plate 43, and the hole is coaxially arranged with the push plate 43. The front end of the fixed plate 41 is fixedly connected to a connecting rod 44, and the shape of the connecting rod 44 is L-shaped. The lower end of the connecting rod 44 is fixedly connected to a slide 45, and the end of the slide 45 close to the positioning rod 38 is fixedly connected to a push block 46. The top view of the push block 46 is a pentagon left after a triangle is cut off from the rear side of a rectangle close to one end of the positioning rod 38. The outer wall of the slide 45 is slidably connected to the inner wall of the mounting block 37.

[0036] Reference Figure 4-Figure 6The fixing assembly 4 also includes a slide rail 47. The outer wall of the slide rail 47 is fixedly connected to the inner wall of the mounting block 37. The top of the slide rail 47 is slidably connected to a fixing ring 48. The shape of the fixing ring 48 is a rectangular parallelepiped with an arc surface at one end close to the positioning rod 38. A triangular groove 49 is provided at the end of the fixing ring 48 away from the positioning rod 38. The top view of the triangular groove 49 is a triangle, and the height of the triangular groove 49 is consistent with the height of the pushing block 46. The pushing block 46 and the triangular groove 49 are at the same height, and the pushing block 46 is at the same height as the triangular groove 49. The angle cutting slope of block 46 is consistent with the hypotenuse slope of triangular groove 49. The outer wall of fixing ring 48 is elastically connected to the inner wall of mounting block 37 by tension spring 2 410. One end of tension spring 2 410 is fixedly connected to the outer wall of fixing ring 48, and the other end of tension spring 2 410 is fixedly connected to the inner wall of mounting block 37. A slide groove 5 is provided at the top of mounting plate 35. The inner wall of slide groove 5 is slidably connected to fixing block 6. A threaded rod 7 is passed through the inner wall of mounting frame 1 and is threadedly connected. Threaded rod 7 has no connection with fixing block 6.

[0037] Working principle: When in use, the staff first places the mounting bracket 1 in a suitable position inside the distribution box, and then leaves the mounting bracket 1 still, so that the mounting ball 31 and the solution inside the control tube 32 flow normally until the pages at the top of the four control tubes 32 are flush. At this time, the buoyancy blocks 33 are at the top of the liquid surface of the control tube 32 under the buoyancy of the solution, so that the mounting plate 35 is in a horizontal state. When the mounting plate 35 is in a horizontal state, the buoyancy gives the positioning rod 38 a force away from the mounting plate 35, and the mounting plate 35 is subjected to the tension of the tension spring 310. Since the tension of the tension spring 310 is less than the buoyancy, the positioning rod 38 can just contact the surface of the mounting plate 35 without affecting the normal movement of the mounting plate 35.

[0038] At this time, the staff rotates the screw 42 so that the screw 42 enters the threaded hole opened in the distribution box, so that the screw 42 fixes the mounting frame 1 to the distribution box while driving the push plate 43 to move backward, so that the push plate 43 drives the fixing plate 41 to move backward, so that the fixing plate 41 drives the connecting rod 44 to move backward, and drives the slide bar 45 to move backward through the connecting rod 44, so that the push block 46 moves backward under the drive of the slide bar 45.

[0039] During the backward movement of the pushing block 46, the fixing ring 48 is pushed by the inclined surface of the triangular groove 49, so that the fixing ring 48 squeezes and fixes the positioning rod 38. Since the fixing ring 48 fixes the positioning rod 38 in the horizontal direction, the vertical position of the positioning rod 38 will not change. Moreover, since the inner side of the fixing ring 48 is made of rubber, when the fixing ring 48 is in contact with the outer wall of the positioning rod 38, the vertical position of the positioning rod 38 cannot be changed.

[0040] When the vertical position of the positioning rod 38 is fixed, the staff puts the electricity meter body 2 on and then rotates the threaded rod 7. When the threaded rod 7 moves to release from the fixing block 6, it drives the fixing block 6 to move toward the direction of the electricity meter body 2. Since the fixing block 6 is arranged above the mounting plate 35, the fixing block 6 and the mounting plate 35 always remain in a vertical state. At this time, since the electricity meter body 2 is in a horizontal state, it is not easy to deviate, and it is squeezed by the fixing block 6, so it is not easy to deviate even if a small vibration occurs. When only the electricity meter body 2 needs to be inspected, it is only necessary to rotate the threaded rod 7. When the threaded rod 7 is no longer in contact with the fixing block 6, the fixing block 6 can be pushed away from the electricity meter body 2 first, and then the electricity meter body 2 can be taken out.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
