Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
Embodiment: as shown in Figure 1, Figure 2 and Figure 3, a kind of low-tension distribution box of good airproof performance of the present invention, including distribution box sheet
Body 1, distribution box ontology 1 are made of cabinet 2 with the chamber door 14 for being hinged on 2 frontal left of cabinet, the fixed peace in the front of 2 inner cavity of cabinet
Equipped with annular slab 3, the front of annular slab 3 is provided with sealing mechanism, and sealing mechanism is by four reset spring 5, one annular clamping plates 6
It is formed with the rubber ring 7 that 14 back side of chamber door is arranged in, annular slab 3 is connect by four reset springs 5 with annular slab 3, cabinet 2
Two sides are fixedly installed with heat dissipation tank 8, and heat release hole 9, the middle part on the outside of 8 inner cavity of heat dissipation tank are offered on the outside of 8 inner cavity of heat dissipation tank
It is fixedly installed with blower 10, blower 10 is CZR-LY60 type blower, and the top of 2 two sides of cabinet offers respectively radiates positioned at two
Mounting hole 11 inside case 8, the inside of two mounting holes 11 are provided with heat sink 12, and two blowers 10 are existed by setting respectively
The internal electric source of heat dissipation switch and cabinet 2 outside two heat dissipation tanks 8 is electrically connected.
Wherein, sealing mechanism further includes four telescopic rods 4, and four are separately positioned on the inside of four reset springs 5, and four
One end of telescopic rod 4 is connect with the positive Corner Strapped of annular slab 3 respectively, the other end of four telescopic rods 4 respectively with marmon clamp
The quadrangle at 6 back side of plate is hinged, can be very good to play a supporting role to annular clamping plate 6 by four telescopic rods 4, makes annular clamping plate
6 move down because of self gravity, and when annular clamping plate 6 is moved forward and backward under the action of 5 restoring force of reset spring, telescopic rod 4 is not
It will affect the movement of annular clamping plate 6, it is practical.
Wherein, one end of reset spring 5 is fixedly connected with the front of annular slab 3, the other end and marmon clamp of reset spring 5
The back side of plate 6 is fixedly connected, and by the restoring force of reset spring 5, when making rubber ring 7 that shrinkage occur, reset spring 5 can be pushed
Annular clamping plate 6 squeezes rubber ring 7, it is made to be squeezed expansion, and then so that the outside of rubber ring 7 is remained unchanged and paste with the inner wall of cabinet 2
It closes, makes that gap will not be generated between rubber ring 7 and cabinet 2, leakproofness is strong.
Wherein, the two sides of mounting hole 11 are provided with fixing bolt, and two fixing bolts pass through external screw thread and heat dissipation respectively
The two sides screw thread of plate 12 is socketed, and by fixing bolt, heat sink 12 is allow firmly to be installed to very much the inside of mounting hole 11, into
And the heat that electronic component generates in cabinet 2 is set to absorb and be dispersed into the inside of heat dissipation tank 8 by heat sink 12, and in blower
It under the action of 10, flow to the hot-air in heat dissipation tank 8 outside heat dissipation tank 8, the electronic component inside cabinet 2 is played
Good heat spreading function.
Wherein, the top of 2 two sides of cabinet is fixedly installed with the rain visor 13 positioned at two 8 tops of heat dissipation tank, and rain cover
The inclination angle of plate 13 is 45 degree, by rain visor 13, when making rain, it is possible to reduce most rainwater passes through heat dissipation

Wherein, the quantity of heat release hole 9 is four, and four heat release holes 9 are distributed in the outside of heat dissipation tank 8 in matrix, by dissipating
Hot hole 9 flow to the hot-air in heat dissipation tank 8 under the blowing of blower 10 outside heat dissipation tank 8.
When work, first when chamber door 14 is closed, during chamber door 14 progressively closes off, chamber door 14 passes through rubber ring 7
Marmon clamp plate 6 is squeezed, annular clamping plate 6 shrinks four telescopic rods 4 and compresses four reset springs 5, when chamber door 14 completely closes
When, four reset springs 5 are in compressive state, and when the decline of the environment temperature of 1 present position of distribution box ontology, rubber ring 7 is sent out
Raw food contracting, by the restoring force of four reset springs 5, one end of four reset springs 5 pushes annular clamping plate 6 to squeeze rubber ring 7,
So that rubber ring 7 is squeezed expansion, and then be bonded the outside of rubber ring 7 still with the inner wall of cabinet 2, makes rubber ring 7 and case
Gap will not be generated between body 2, when the electronic device inside cabinet 2 works, the heat of generation can be by two heat sinks 12
It absorbs, the heat that two heat sinks 12 absorb is dispersed into the inside of two heat dissipation tanks 8, and heats the sky inside two heat dissipation tanks 8
Gas opens two heat dissipation switches, so that two blowers 10 is worked, and flow the air inside two heat dissipation tanks 8, hot-air is final
The inside of two heat dissipation tanks 8 is flowed out by heat release hole 9, is realized heat exchange, is radiated to the inside of cabinet 2, prevent electronics device
Part temperature is excessively high and damages.
