Arrange protection casing perpendicularly and use drawer cabinet of this protection casing

The utility model relates to an arrange protection casing perpendicularly and use drawer cabinet of this protection casing to solve among the prior art with high costs, the processing problem long in time limit of protection casing manufacturing that integral protection rear cover can not the large -scale production storage causes. Resolve into the modularization apron of the different specifications of polylith through the monoblock back shroud with among the prior art, realized the manufacturing of extensive, the batchization of protection casing, improved productivity, reduced labour cost, the form of fritter processing simultaneously also is favorable to using the corner material, has improved material utilization rate, and more furtherly has practiced thrift the processing cost. Connect insulating upper end shrouding and lower extreme shrouding respectively through the last lower extreme at the protection casing, avoided effectively that metalworks such as bolt are not hard up, the toy climb into etc. The drawer cabinet short circuit accident that leads to the fact of reason, the use reliability and the security that have improved the drawer cabinet.
