Moved downward under the action of lower Lock spring 95, lower latch recess 91 is protruded into lower 93 left end of clamping block, lower Lock spring 95 by
Full compression state becomes state half-compressed, and vertical sliding block 87 moves upwards under the effect of lower clamping block 93, locks bullet due to upper at this time
Spring 78 is in relaxed state, and upper clamping block 76 moves right under the effect of vertical sliding block 87, and upper Lock spring 78 is become by relaxed state
For state half-compressed, latch recess 74 is left in upper 76 left end of clamping block, under the action of upper pop-up spring 14, upper pop-up
Sliding block 73 pops up downwards, and vertical sliding block 87, which moves upwards, can drive catenating slider 58 to move upwards, so that decline bevel gear 53 and electricity
Machine bevel gear 56 separate, rise bevel gear 52 engaged with motor bevel gear 56 so that 24 rotation direction of elevating screw on the contrary,
Elevator 25 changes direction and moves upwards, simultaneously because lower clamping block 93 moves downward, connection sliding block 71 is driven to move downward, into
And fan bevel gear 63 is made to separate with decline fan bevel gear 66 and engage with fan bevel gear 65 is risen, due to being driven at this time
35 direction synchronous backward of horizontal axis, then the rotation direction of fan shaft 62 is constant, when elevator 25 moves upwards, due to lower clamping block
93 are located in lower latch recess 91, and lower pop-up sliding block 89 can not be popped up to main sliding chamber 23, and lower compression cross slider 17 is lower multiple
Position spring 16 protrudes into main sliding chamber 23 under acting on to the left, so that lower Lock spring 95 becomes relaxed state from state half-compressed.
When compressing 84 corresponding position of cross slider in the arrival of elevator 25, elevator 25 presses to the right upper compression cross slider 84
Enter in upper compression sideslip chamber 83, and then upper spring briquetting 79 is pushed to be moved to the left, so that upper Lock spring 78 is by state half-compressed
Become full compression state, when upper pop-up sliding block 73 is completely forced into upper pop-up upwards by elevator 25 slides chamber 72, on elevator 25
End face is abutted with main sliding 23 upper end wall surface of chamber, and upper clamping block 76 makes upper clamping block 76 left to the left under the effect of upper Lock spring 78
End is protruded into latch recess 74, and upper Lock spring 78 becomes state half-compressed from full compression, founds sliding block 87 in upper mating groove
It is moved downward under 77 effects, lower mating groove 94 is protruded into vertical 87 lower end of sliding block, so that lower clamping block 93 moves right and leaves
Lower latch recess 91, so that lower Lock spring 95 becomes state half-compressed from relaxation, lower pop-up sliding block 89 is in lower pop-up spring 15
It is popped up under effect to main sliding chamber 23, vertical sliding block 87 moves downward, and drives catenating slider 58 to move downward, so that rising cone tooth
Wheel 52 is separated with motor bevel gear 56, and decline bevel gear 53 engages with motor bevel gear 56, so that 24 rotation direction of elevating screw
On the contrary, it is to move downward that elevator 25, which changes direction, simultaneously because lower clamping block 93 moves right, 71 casees right sides of connection sliding block are driven
Movement, so that fan bevel gear 63 separates with rising fan bevel gear 65 and engages with decline fan bevel gear 66, in turn
So that 62 rotation direction of fan shaft remains unchanged, when elevator 25 moves downward, since upper 76 left end of clamping block is located at locking
Determine in groove 74, upper pop-up sliding block 73 can not pop up downwards, and upper compression cross slider 84 protrudes under the action of upper reset spring 85
Main sliding chamber 23, so that upper spring briquetting 79 moves right, so that upper Lock spring 78 becomes the shape that relaxes from state half-compressed
State, device return to original state, and reciprocation cycle.
The beneficial effects of the present invention are: the present invention by electric heating cabinet air in the way of dehumidify to power distribution cabinet, together
When fan is installed, help cabinet inner air flow, improve effect on moisture extraction, accelerate dehumidifying speed, heater under the drive of device on
Lower reciprocating motion so that air heats are uniform in cabinet body, while avoiding internal electric equipment from being made for a long time by high-temperature baking
Forming apparatus high temperature ageing.
In the above manner, those skilled in the art can be made within the scope of the invention according to operating mode it is various
Change.
