To realize the quick conduction of heat.Such mode is higher to technique and cost requirement, at the same on the integral layout of cabinet influence compared with
Greatly, cabinet overall dimensions be will lead to and weight increases, many times since the limitation of space and load-carrying can not achieve.
It is connect in addition, reinforcing module drawing-aid device and generally passing through axle screw with reinforcing cover board, axle screw generally uses band cylinder
The stepped screw in face is directly threadedly coupled with cover board is reinforced, while being matched between axle screw and drawing-aid device, reinforcing cover board using gap
The mode of conjunction guarantees the active state of drawing-aid device.Such mode is higher to screw and hole processing required precision, slightly misses
Difference will lead to drawing-aid device tension or excessively loose.Drawing-aid device is pulled when tension will lead to axle screw rotate together with drawing-aid device, spiral shell
Nail loosens；Drawing-aid device can shake in cabinet always when crossing pine.Need due to reinforcing module plug compared with great dynamics, when axle screw with
When the threaded hole coaxiality deviation in circular shaft hole and reinforcing cover board on drawing-aid device is larger, screw bending, fracture can be also generated
Risk.
