The connected linkage of connecting rod 104 of imperial connector 106, which touches, turns round 102.
Although above-mentioned door bottom automatic seal strip can drive dust seal to slide up and down by dust-proof sealing device, so as to
Bottom is sealed on the door.But above-mentioned driving structure needs the adjustment screw for being arranged with spring to drive left Buddhist nun indirectly by connecting rod
Imperial connector, so as to which dust-proof sealing device be controlled to push the lifting of dust seal.Using touch torsion, spring, adjustment screw with
And the above-mentioned dust-proof sealing device trigger architecture of connecting rod, drive mechanism is complicated, and trigger architecture needs to occupy the more fan of door body
Width space so as to the volume for dust-proof sealing device of having to control, will appear sky even for the door body structure of some clamshell doors
Between deficiency the problem of can not installing above-mentioned door bottom automatic seal strip.Also, above structure needs spring being nested in adjustment screw
On, the volume and length that lead to spring can all be limited, and can not use the spring of volume bigger, and spring is easily damaged, and is driven
The connecting rod of left nylon connectors also because the factor of volume causes it to be easily damaged, also results in a bottom automatic seal strip
Reliability can not ensure.
