Specific implementation mode
Detailed description below is referring to figs. 1 to Fig. 7.
A kind of conducting wire mounting assembly of anti-explosion ventilator is mounted on the air duct 10 of anti-explosion ventilator, is opened on the air duct
If through-hole 100, the conducting wire mounting assembly 20 includes parent part 21 and bull 22, and parent part includes female threaded joint 211 and elasticity
Canister portion 212, bull include male threaded joint 221 and expansion bar portion 222, and the bull is hollow.
The periphery of female threaded joint 211 is equipped with the first defining flange 213, the first defining flange and elastic canister portion 212
Periphery forms step.
The periphery for expanding bar portion 222 is equipped with the second defining flange 223, and the second defining flange is located at the end of expansion bar portion,
Second defining flange forms step with expansion bar portion.
The material for expanding bar portion is rigid material, and the material of elastic canister portion is rubber.
Be inlaid with several rigidity bars 214 on the madial wall of elastic canister portion 212, several rigidity bars along elastic canister portions circumference to
It is uniformly distributed.The length of rigidity bar 214 is less than the length of elastic canister portion 212, and the length of rigidity bar is less than or equal to the through-hole
100 length, the head end of rigidity bar are flushed with the head end of elastic canister portion, and head end and the female threaded joint 211 of elastic canister portion connect
It connects.Wherein, the rigidity bar can ensure that bull is smoothly inserted into parent part.
In practical operation, parent part 21 is plugged in the through-hole 100 of air duct 10, and the first defining flange 213 on parent part compresses
On the madial wall of air duct.
Connection explosion-proof variable frequency motor and the conducting wire of frequency-variable controller are threaded through in the hollow cavity 220 of bull 22, bull 22 by
Elastic canister portion 212 is plugged in parent part 21, is located at the wind threaded joints of the male threaded joint 221 and parent part on bull top
211 are spirally connected, and for the expansion bar portion 222 of bull by 212 distending of the elastic canister portion, epistasis canister portion is pressed on the madial wall of through-hole 100
On.
As bull 22 deepens continuously parent part 21, the second defining flange 223 of bull squeezes the end of elastic canister portion 212,
Since the length of rigidity bar 214 is less than the length of elastic canister portion 212, by the end of the elastic canister portion of the second defining flange 223
Portion deforms, and plays the role of sealing through-hole 100.Second defining flange 223 is pressed on the lateral wall of air duct 10.
