Detailed Description

The present invention will be further explained with reference to the drawings and examples.

Example 1: this embodiment aims at providing a support in the frequency conversion cabinet, the support mounting is internal at the cabinet, as electrical component's installing support, to the defect that exists on the supporting structure in the current frequency conversion cabinet, it needs the internal installation at the cabinet to have caused when installation electrical component, because the internal space of cabinet is narrow and small, the installation that will accomplish electrical component simultaneously needs a plurality of fixing bolt of operation just can fix an electrical component on the support, consuming time and wasting power, huge trouble has been brought for constructor, this embodiment provides a support that allows at the external installation electrical component of cabinet according to current supporting structure.

For this purpose, as shown in fig. 1, the support comprises a vertical support 1, a horizontal support 2, an arc-shaped support 3, a fixed hanging plate 4 and a fixed bolt 8; the vertical braces 1 are arranged in the cabinet body at intervals along the vertical direction, and the cross braces 2 are arranged in the cabinet body along the transverse direction; arc supports 3 and stull 2 from top to bottom sets up on erectting to prop 1 in proper order in turn, as shown in fig. 1, arc supports 3 last, and stull 2 is under, and middle part, right side and left side between them all fix on different erects props (three) to this is a basic support unit, as the fixed stay frame of fixed link plate.

In order to make the installation that fixed link plate 4 can be quick on the support, in this embodiment, arc supports 3 be the symmetrical structure that the high both ends in middle part are low, as shown in fig. 1, arc supports 3 and is a continuous arc structure, and the middle part is the circular arc structure that has certain radian, and both sides are the linear structure that has certain inclination, and the middle part that arc supported 3 is fixed on erectting to prop 1.

As shown in fig. 2, two sides of the upper part of the fixed hanging plate 4 extend upwards to form hanging lugs 6, the center of the lower part of the fixed hanging plate extends downwards to form a fixed plate 7, the hanging lugs 6 on the two sides are symmetrical relative to the fixed plate 7, and the hanging lugs and the fixed plate can be fixed by welding or bolt connection; install electrical component 5 on fixed link plate 4, fixed link plate 4 hangs two shoulders (linear structure) that the arc supported 3 through hangers 6, and fixed link plate 4 when taking place to remove, its action resolvable for horizontal and vertical motion, when taking place lateral shifting, hangers 6 of both sides must be followed the arc and supported 3 upwards or climb downwards, but because the hangers of both sides are drawn each other, make fixed link plate can not follow lateral shifting.

In order to limit the vertical movement of the fixed hanging plate 4, the fixed plate 7 is provided with a fixed hole, the vertical support 1 is provided with a screw hole, and the fixed bolt 8 penetrates through the fixed hole and is in threaded connection with the screw hole, so that the fixed hanging plate 4 is fixed on the vertical support 1, and the fixed hanging plate 4 cannot move vertically.

As shown in fig. 2, in order to ensure that the fixed hanging plate 4 can keep a horizontal state on the bracket, the width of the hanging groove 61 of the hanging lug is the same as the thickness of the arc-shaped support 3, so that the hanging lug 6 is hung on the arc-shaped support 3 in a matching way; the inner side wall of the hanging groove is flush with the back surface of the fixed hanging plate; the fixed plate is located the bottom of fixed link plate, and the back of fixed plate flushes with the back of fixed link plate to the back and the vertical braces laminating of fixed link plate ensure the stability of fixed link plate 4.

Example 2: this example is substantially the same as example 1, except that: the present embodiment further defines the structure of the set screw.

As shown in fig. 1, fix electrical component 5 on fixed link plate outside the cabinet body, still need the constructor to get into the cabinet body afterwards and fix fixed link plate on the support, in order to simplify the installation, this embodiment is for the hand nut screwing with fixing bolt 8, only needs to fix a fixing bolt on erectting through manual operation admittedly, can accomplish the installation of fixed link plate, easy operation, great simplification the operating procedure, saved the manpower, give people and brought very big facility.

Meanwhile, the plurality of electric elements 5 are arranged on the fixed hanging plate 4, so that the fixed hanging plate can be used as an installation support plate for the plurality of electric elements, the plurality of electric elements can be firmly installed on the fixed hanging plate at the outer side, the fixed hanging plate 4 is fixed on the bracket through screwing the bolt by one hand, time and labor are saved, time is saved, great convenience is provided for the frequency conversion cabinet to install the electric elements, and the frequency conversion cabinet has great popularization value.
