Description

Technical Field

[0001] This utility model relates to the field of meter box technology, specifically a telescopic meter box mounting bracket. Background Technology

[0002] An electricity meter box is a protective device used to install electricity metering instruments. Its main function is to protect the electricity metering instruments and lines, and to prevent the electricity metering instruments from becoming unstable or causing safety hazards due to external factors. It is usually installed at the inlet and outlet of the power system to protect and maintain the electricity meter. When installing an electricity meter box, it is usually used in conjunction with a mounting bracket. Some lighter electricity meter boxes do not need to be fixed with bolts or other fasteners; they can simply be placed inside the appropriate mounting bracket.

[0003] Currently used mounting brackets are typically fixed in one place with bolts. However, the mounting brackets themselves do not have the function of protecting the bolts. The bolts are exposed to the outdoor environment and are easily corroded by rainwater, moisture, salt and other corrosive substances. Corrosion will cause rust to appear on the surface of the bolts, reducing their strength and fastening effect. In severe cases, it may cause the bolts to break. Furthermore, some mounting brackets do not have the function of telescopic movement for the parts that clamp the meter box. When different sizes of meter boxes need to be installed, it may be necessary to replace the entire mounting bracket, which increases the installation cost and complexity. More precise measurement and positioning are required, which increases the difficulty and time of installation. When the meter box needs to be repaired or replaced, it is necessary to remove part of the mounting bracket or make complex adjustments. Utility Model Content

[0020] 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.

[0021] Please see Figure 1-4 As shown, a telescopic meter box mounting bracket includes a mounting bracket 1. A support seat 2 is bolted to one side of the mounting bracket 1, allowing the meter box to be placed on top of the support seat 2. Six bolts 3 are threaded onto the surface of the mounting bracket 1, distributed on the six sides of the mounting bracket 1. The bolts 3 secure the mounting bracket 1 in place. Protective covers 4 are rotatably connected to both sides of the mounting bracket 1, shielding the bolts 3 when the protective covers 4 are rotated to the appropriate position. Positioning mechanisms 5 are provided on both sides of the top of the mounting bracket 1, preventing the protective covers 4 from rotating easily. Moving plates 6 are slidably connected to both sides of the top of the support seat 2. A mounting groove 7 is provided inside the support seat 2, and a transmission mechanism 8 is installed inside the mounting groove 7. A transmission block 9 is slidably connected to the inner wall of the top of the support seat 2. There are six blocks 9. The transmission mechanism 8 works in conjunction with the transmission blocks 9. When the transmission mechanism 8 is running, it can move the corresponding transmission blocks 9 in opposite directions. The top of the transmission block 9 is bolted to one side of the bottom of the moving plate 6. When the transmission block 9 moves, it can drive the moving plate 6 to move. When the two moving plates 6 on both sides move to the appropriate position in opposite directions, they can clamp and position the meter box. A fixing block 10 is bolted to one side of the bottom of the inner wall of the mounting groove 7. The transmission mechanism 8 works in conjunction with the fixing block 10. Under the action of the fixing block 10, the internal parts of the transmission mechanism 8 can be supported. Slide grooves 11 are opened on both sides of the surface of the mounting bracket 1. Sliding sliders 12 are slidably connected to both sides of the inner wall of the slide groove 11. One side of the surface of the slider 12 is bolted to one side of the surface of the moving plate 6. Under the action of the slider 12, the moving plate 6 moves more stably.

[0022] The positioning mechanism 5 includes a fixed frame 51. One side of the inner wall of the fixed frame 51 is bolted to one side of the surface of the mounting frame 1. A slide rod 52 is slidably connected to the inner wall of the fixed frame 51. A positioning plate 53 is bolted to the bottom of the slide rod 52. A compression spring 54 is fixedly connected to one side of the lower surface of the fixed frame 51. The other end of the surface of the compression spring 54 is fixedly connected to one side of the top of the positioning plate 53. The positioning plate 53 is L-shaped and one side of the surface of the positioning plate 53 is inclined. When the protective cover 4 rotates and contacts the positioning plate 53, the positioning plate 53 can be raised. When the positioning plate 53 is raised, the compression spring 54 can be compressed. The outer diameter of the top of the slide rod 52 is larger than the outer diameter of the bottom of the slide rod 52. Under this action, it is convenient for the staff to pull the slide rod 52.

[0023] The transmission mechanism 8 includes a rotating rod 81. One side of the surface of the rotating rod 81 is rotatably connected to one side of the surface of the bearing seat 2. Both sides of the inner wall of the mounting groove 7 are rotatably connected to a double-threaded rod 82. The other end of the surface of the double-threaded rod 82 is bolted with a bevel gear 83. The inner wall of one side of the bevel gear 83 is bolted to one side of the surface of the rotating rod 81. When the rotating rod 81 rotates, it can drive the bevel gear 83 on one side to rotate. The opposite surfaces of the two bevel gears 83 are bolted with a connecting rod 84. When one side of the bevel gear 83 rotates, it can drive the connecting rod 84. 4. Rotation: One side of the surface of the connecting rod 84 is rotatably connected to the inner wall of the fixed block 10. When the connecting rod 84 rotates, it can drive the bevel gear 83 on the other side to rotate. When the bevel gear 83 rotates, it can drive the bidirectional threaded rod 82 to rotate. Both sides of the surface of the bidirectional threaded rod 82 on both sides are threadedly connected to the moving seat 85. When the bidirectional threaded rod 82 on both sides rotates, it can cause the moving seat 85 on both sides to move in opposite directions. One side of the top of the moving seat 85 is bolted to the bottom of the transmission block 9. When the moving seat 85 moves, it can drive the transmission block 9 to move.

[0024] Working principle: When the mounting bracket 1 is fixed in one place, rotate one side of the protective cover 4. When the protective cover 4 rotates to the appropriate position, it can contact the positioning plate 53. Then, as the protective cover 4 continues to rotate, the positioning plate 53 rises. Next, the rising of the positioning plate 53 causes the slide rod 52 to rise. At the same time, when the positioning plate 53 rises, the compression spring 54 is compressed. Then, when the protective cover 4 rotates to its maximum distance, it can block the three bolts 3. Then, under the action of the compression spring 54, the positioning plate 53 falls back to its original position. Under this action, the protective cover 4 is positioned, preventing it from rotating easily. Then, rotating the other side of the protective cover 4 can similarly block the other three bolts. 3. When the size of the meter box does not match the distance between the two movable plates 6, rotate the rotating rod 81. When the rotating rod 81 rotates, it can drive the bevel gear 83 on one side to rotate. Then, the rotation of the bevel gear 83 on one side can drive the connecting rod 84 to rotate. Next, the rotation of the connecting rod 84 can drive the bevel gear 83 on the other side to rotate. When the bevel gear 83 rotates, it can drive the double-threaded rod 82 to rotate. Then, the rotation of the double-threaded rods 82 on both sides can cause the movable seats 85 on both sides to move in opposite directions. When the movable seats 85 move, they can drive the transmission block 9 to move. Then, the movement of the transmission block 9 can cause the movable plate 6 to move. Next, when the two movable plates 6 on both sides move to the appropriate position, they can clamp and position the meter box.
