[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-6 As shown, a heat dissipation electric meter box of an embodiment of the utility model includes a box body 1 and a box cover 10 arranged on the front side of the box body 1, heat dissipation openings 11 are provided on the left and right sides of the box body 1, a heat dissipation plate 2 is installed in the heat dissipation opening 11, and a plurality of heat dissipation grooves 20 are arranged in an array on the heat dissipation plate 2, two limiting grooves 21 are correspondingly provided at the upper and lower ends of the heat dissipation plate 2, and limiting mechanisms are provided at the inner walls of the left and right sides of the box body 1 corresponding to the limiting grooves 21, and the limiting mechanisms and the limiting grooves 21 form limiting locking or unlocking to realize the loading and unloading of the heat dissipation plate 2.

[0023] When in use, the heat sink 2 is installed at the heat dissipation opening 11. An array of heat dissipation grooves 20 are provided on the heat sink 2 to facilitate the interaction of air inside and outside the box 1, thereby ensuring the heat dissipation performance of the box 1. The heat sink 2 is locked or unlocked by a limiting mechanism and a limiting groove 21. It can be detachably arranged in the heat dissipation opening 11 for daily maintenance and replacement. The loading and unloading of the heat sink 2 can only be performed from inside the box 1, effectively improving the safety performance of the meter box.

[0024] A receiving cavity 22 is formed inside the heat dissipation plate 2 , and each heat dissipation slot 20 is connected to the receiving cavity 22 . A mounting slot 23 connected to the receiving cavity 22 is formed on one side of the heat dissipation plate 2 , and a dustproof net 24 is inserted in the mounting slot 23 .

[0025] During use, the dustproof net 24 is inserted into the installation slot 23 in daily use. When the dustproof net 24 is installed, it is located between the inner and outer openings of each heat dissipation port 11. The dustproof net 24 isolates the dust in the air entering the interior of the box 1 to ensure the dustproof performance of the box 1; when the heat sink 2 is installed, the inner wall of the heat dissipation port 11 forms a barrier to the dustproof net 24 to prevent the dustproof net 24 from being separated from the installation position.

[0026] A protective baffle 25 is disposed on the outer surface of the heat dissipation plate 2 above each heat dissipation slot 20 .

[0027] When in use, the protective baffle 25 is provided to protect the heat dissipation slot 20 to prevent external rain and snow from entering the box body 1 through the heat dissipation slot 20 in rainy and snowy weather, thereby ensuring waterproof performance.

[0028] The limiting mechanism includes a fixed plate 3 fixed to the inner wall of the box body 1, and a positioning frame 30 is slidably arranged on the fixed plate 3, and the positioning frame 30 has a limiting block 31 adapted to the limiting groove 21; the positioning frame 30 includes two frame plates 32, and a positioning column 33 is connected between the two frame plates 32, and each positioning column 33 is slidably matched with the fixed plate 3 and an outer ring is provided with a spring member 34; the frame plate 32 on the side away from the heat dissipation outlet 11 is connected to a fixed seat 35, and the fixed seat 35 is rotatably connected to a U-shaped piece 36, and the U-shaped piece 36 is connected to a pull rod 37 through two fixed rods, and a limiting seat 4 is arranged at the corresponding position of the two pull rods 37 on the inner wall of the box body 1.

[0029] When in use, the outer ring of each positioning column 33 is sleeved with a spring member 34. When the heat sink 2 is installed, the positioning frame 30 drives the limit block 31 into the limit groove 21 due to the force of the spring member 34, and the heat sink 2 is locked and limited by the limit clamping between the limit block 31 and the limit groove 21.

[0030] When the heat sink 2 needs to be disassembled, the control pull rod 37 pulls the fixing seat 35 and the positioning frame 30 to slide away from the heat dissipation opening 11. The sliding path of the positioning frame 30 is limited by the sliding cooperation between the two positioning columns 33 and the fixing plate 3. While the positioning frame 30 slides, the spring member 34 is pressed and the spring member 34 is in an energy storage state. The pull rod 37 is pulled until the corresponding limit block 31 exits the limit groove 21, that is, the limit clamping between the limit block 31 and the limit groove 21 disappears. At this time, the heat sink 2 is unlocked and can be disassembled.

[0031] Among them, an assembly part is formed on the outer edge of the heat sink 2, and an assembly recess adapted to the assembly part is formed on the outer opening end of the heat dissipation passage 11. When the heat sink 2 is installed, the assembly part is located in the assembly recess, and the installation stability of the heat sink 2 is ensured by the cooperation between the assembly part and the assembly recess.

[0032] A receiving recess 40 is formed at the front end of the limiting seat 4 , and a first matching groove 41 and a second matching groove 42 adapted to the pull rod 37 are formed on both sides of the receiving recess 40 .

[0033] When in use, the pull rod 37 is located in the first matching groove 41 when the heat sink 2 is locked, so that the pull rod 37 does not occupy the internal space of the box body 1; when the heat sink 2 is unlocked, the pull rod 37 is located in the second matching groove 42, and the positioning frame 30 and the limit block 31 are kept unlocked by the cooperation between the pull rod 37 and the second matching groove 42, so that the heat sink 2 is easily loaded and unloaded;

[0034] Furthermore, both ends of the pull rod 37 have limiting plates, the size of which is larger than the size of the pull rod 37 , thereby limiting the pull rod 37 in the first matching groove 41 or the second matching groove 42 .

[0035] It should also be pointed out that the terms used in the present invention, such as “front”, “rear”, “vertical”, “horizontal”, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention.

[0036] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
