Part, second connecting portion part are constituted between the pedestal and described first connecting portion part and are threadedly coupled；It is characterized by: institute
It constitutes and is threadedly coupled between the cabinet door stated and the second connecting portion part, offer fixation on the second connecting portion part
Hole offers cabinet door mounting hole, passes through between the cabinet door mounting hole and mounting hole correspondingly in the cabinet door
The cooperation of bolts and nuts and realize threaded connection.
On this basis, mounting hole is offered on the pedestal, is formed with step on the mating bolt, it is described
Step is matched with the mounting hole.
On this basis, the switchgear further includes a support frame, and the support frame is installed on the one of mating bolt
Side, the installation for switchgear.
On this basis, described first connecting portion part includes matching nut and mating bolt, and the matching nut is solid
It is scheduled in the cavity constituted with support frame body end, and is in contact with the cavity inner wall, the mating bolt is worn
Pedestal is crossed to screw with matching nut.
On this basis, it constitutes and is threadedly coupled between the side panel and the support frame body.
On this basis, the matching nut is fixed by fixing bolt and support frame body.
Compared with prior art, the beneficial effects of the present invention are: matching nut is located in the cavity of bracket end, and with it is solid
Cavity contact, the installation site of such matching nut reliably limited, when by mating bolt pass through pedestal with it is above-mentioned mating
After nut cooperation is fixed, have pedestal positioning reliable, the high advantage of installation accuracy.

Specific embodiment
In order to enable the auditor especially public of Patent Office that technical spirit of the invention is more clearly understood and have
Beneficial effect, applicant will elaborate in conjunction with attached drawing by way of examples below, but not to the description of embodiment
It is the limitation to technical solution of the present invention, it is only formal but not substantive made by any design according to the present invention
Equivalent transformation is regarded as technical solution of the present invention scope.
Please refer to Fig. 1, a kind of detachable switchgear, including pedestal 1, side panel 2, bracket 3 and cabinet door 4
, the pedestal 1 side panel 2, bracket 3, is fixed to each other between cabinet door 4 using screw thread.Switch cabinet shell body is for holding
Receive internal electric elements, above-mentioned pedestal 1, side panel 2, bracket 3 and cabinet door 4 form the sky of a relative closure
Between.
It is threadedly coupled the cooperation for typically referring to cooperation or bolts and nuts using bolts and nuts, more in turn, a part
Using the fit system of bolts and nuts, and another part then uses the fit system of bolts and nuts.Certainly above-mentioned spiral shell is used
Bolt, bolt, the similar part of nut but its function it is equivalent if, also should belong to the range that technical solution of the present invention is protected.
For example: being first threadedly coupled pedestal 1 and four brackets 3, then with same thread connecting mode by four
Block side panel 2 is installed on bracket 3, last that cabinet door 4 is equally installed on bracket 3 by the way of being threadedly coupled
On.The positioning that above-mentioned detachable mounting means is considered as between each components is reliable, to avoid there is installation error.
Please continue to refer to Fig. 1 and Fig. 2 is combined, bracket 3 of the present invention includes support frame body 31, first
Connecting component 32, second connecting portion part 33, described first connecting portion part 32 is used to fix with pedestal 1, described
Second connecting portion part 33 is used for fixed with cabinet door 4.Support frame body 31 is strip metal member, by sheet metal bending
