Member accidentally touches emergency switch and equipment is caused promptly to stall, and may result in serious consequence, then just there is emergency stop switch protection
The appearance of cover, but simultaneously also due to installed protective cover additional, lower button can not be pressed at the first time in emergency, existed as a result,
Entire industry produces certain arguement, and country also has specific regulation not to this, only provides to need in any case
It installs protective cover additional, is not necessarily to install protective cover additional in some inessential situations, but in general, security risk still has.
Utility model content
The purpose of this utility model is in view of the above problems, providing a kind of power equipment switch protection cover, it is intended to for the
One time can press rapidly scram button, avoid the generation of security risk.
In order to achieve the above object, the technical solution adopted in the utility model is: it includes protection cover body, the protective cover
There is the inner sleeve of lower ending opening, the inner sleeve is interior to be lifted with press unit, tube wall two sides by the first spring in the middle part of ontology
Equipped with open slot, so that link assembly one end is passed through open slot and connect press unit, the link assembly other end is hinged on installation
On seat, it is connect by guide block with unit is pulled, the guide block is movably arranged in the channel of mounting base.
Further, wherein pulling unit includes the capping connecting with protective cover body side open-top screw thread, the capping
It is inside provided with a pulling block, is connected with second spring between the pulling block and capping, the outside portion of pulling block is provided with pulling mouth, inside portion
Guide block is connected by conducting wire.
Further, protection cover body is stretched out in the inner sleeve lower end, has external screw thread on extension end.
Compared with prior art, the utility model has the beneficial effects that unexpected touch tightly can effectively be avoided by having installed protective cover additional
Anxious switch, while also can complete the push action of emergency switch by quickly pulling pulling mouth, make the two bring security risk all
It can effectively be solved.
