It is tired, it is less efficient, while the accuracy installed, precision are relatively low.
Utility model content
In view of the deficiencies of the prior art, the purpose of this utility model is that a kind of installation accuracy is high, there is pre-installation effect
It is a kind of with wall bushing pre-installation structure switchgear.
To achieve the above object, scheme provided by the utility model is：A kind of opening with wall bushing pre-installation structure
Cabinet is closed, it is described through walls including cabinet plate, wall bushing installing plate and installation and through the wall bushing of wall bushing installing plate
The rectangular plate body of casing installing plate and there is rectangle installation base in its bead formed on back, wherein, the wall bushing installs back
Also there are four the mounting posts for being located at its four angles respectively for molding；The cabinet plate includes the square for rectangle installation base installation
Shape installation cavity and respectively four mounting grooves matched with the mounting post；It is recessed that connection is provided among each mounting post
Slot, wherein, the connecting groove bottom forms cross section in the fool proof cutting of semicircle shape and offers through wall bushing
First threaded hole of installation；Each installation trench bottom form with the matched connection boss of the connecting groove, it is described
The fool proof slot for supplying fool proof cutting insertion is formed on connection boss and is offered and is aligned with first threaded hole
The second threaded hole.
Further, the screw thread lines of first threaded hole is identical with the screw thread lines of the second threaded hole.
The advantageous effect of the utility model against existing technologies is to pass through the mounting post on wall bushing installing plate and cabinet plate
The cooperation of upper mounting groove and the cooperation of rectangle installation base and rectangle installation cavity so that wall bushing installing plate is pre-installed on cabinet
On plate, while the first threaded hole aligns with the second threaded hole, as long as directly in positive first screw thread of wall bushing installing plate
Screw is inserted on hole to fix, it is simple and quick, it greatly improves installation accuracy and also provides structural soundness simultaneously；And
And the cooperation by setting fool proof cutting and fool proof slot, play the role of fool proof to the process of installation.

Specific embodiment
With reference to specific embodiment, the utility model is described in further detail：
With reference to shown in attached drawing 1 to 6, the utility model is a kind of switchgear with wall bushing pre-installation structure, including
There are cabinet plate 1, wall bushing installing plate 2 and installation and through the wall bushing 3 of wall bushing installing plate 2；The wall bushing
2 rectangular plate body of installing plate and there is rectangle installation base 21 in its bead formed on back, wherein, 2 back side of wall bushing installing plate is also
There are four the mounting posts 22 for being located at its four angles respectively for molding；The cabinet plate 1 includes the square installed for the rectangle installation base 21
Shape installation cavity 11 and respectively with 22 matched four mounting grooves 12 of the mounting post；Round connect is provided among each mounting post 22
Groove 221 is connect, wherein, the bottom of the connecting groove 221 offers the first threaded hole 221b through wall bushing installing plate 2；
Each 12 bottom of mounting groove form with the matched connection boss 121 of the connecting groove 221, open up on the connection boss 121
Have the second threaded hole 121b to align with first threaded hole 221b, wherein, the screw thread lines of second threaded hole 121b with
The screw thread lines of first threaded hole 221b is identical；During installation, wall bushing is mounted on wall bushing installing plate 2 in advance, so
Cooperation by rectangle installation cavity 11 on the rectangle installation base 21 on wall bushing installing plate 2 and cabinet plate 1 and set through walls afterwards
