Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
Referring to fig. 1-2, a housing of a miniature frequency converter comprises a housing 1, two heat dissipation holes 2 are symmetrically formed in inner walls of two sides of the housing 1, a heat dissipation screen 6 is clamped in each of the two heat dissipation holes 2, and two stoppers 3 are fixedly mounted on the inner walls of the two heat dissipation holes 2;
the following two points are notable:
1. every dog 3 all has magnetism, and the magnetism that dog 3 is close to bar magnetic pole 4 one side is opposite with the magnetism that bar magnetic pole 4 kept away from heat dissipation otter board 6 one side, certain actuation effect has when here utilizes dog 3 and the opposite contact of bar magnetic pole 4 magnetism, thereby make the more firm of heat dissipation otter board 6 block on louvre 2 (here bar magnetic board 9 is greater than the sum of the frictional force that dog 3 received to bar magnetic pole 4's suction and heat dissipation otter board 6 in louvre 2 to the biggest repulsive force of corresponding bar magnetic pole 4, ensure that heat dissipation otter board 6 can shift out from louvre 2 under bar magnetic board 9's repulsive interaction.
2. All the outer walls of the two heat dissipation screen plates 6 are sleeved with a rubber pad 13, and the purpose of the rubber pads 13 is to utilize the elasticity of the rubber pads to enable the heat dissipation screen plates 6 to be clamped and installed in the heat dissipation holes 2 more stably.
One side that two heat dissipation otter boards 6 are close to each other all has two bar magnetic poles 4 through 5 fixed mounting of four connecting rods, and the purpose that bar magnetic pole 4 set up is convenient for cooperate with bar magnetic slab 9, realizes that heat dissipation otter board 6 dismantles from louvre 2 fast.
Two arc-shaped cover bodies 7 are fixedly arranged in the shell 1, a rotating shaft 8 is rotatably arranged in each of the two arc-shaped cover bodies 7, the rotating shaft 8 penetrates through the arc-shaped cover bodies 7 and the shell 1 and is fixedly provided with a knob 10, and a strip-shaped magnetic plate 9 is fixedly sleeved on each of the two rotating shafts 8;
it is worth noting above that: a plurality of ventilative meshes have all been seted up on the outer wall of two arc cover bodies 7, and the setting of ventilative mesh makes the setting of arc cover body 7 play certain isolation protection to rotatable bar magnetic sheet 9, and is low to the influence that gas flow produced.
