Detailed Description

In order that the present invention may be more readily and clearly understood, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments that are illustrated in the appended drawings.

Referring to fig. 1 and fig. 2, in view of this, the first embodiment of the present invention provides a low voltage switch cabinet convenient for maintenance and repair, including the cabinet body 1 in the shape of a rectangular parallelepiped, the front end of the cabinet body 1 is hinged with a cabinet door 2, and the cabinet door 2 can be turned around a hinge shaft, so as to open or close the cabinet body 1.

The inner side surface of the cabinet door 2 is provided with a heightening pedal 3. The lower end of the heightening pedal 3 is hinged with the inner side surface of the cabinet door 2, and a hinged shaft between the heightening pedal 3 and the cabinet door 2 is arranged along the horizontal direction, so that the heightening pedal 3 can be overturned up and down around the hinged shaft. The other end of the heightening pedal 3 is fixedly provided with a bearing plate 4 which is vertical to the heightening pedal 3. When cabinet door 2 is in the open mode, and increase footboard 3 and wind the articulated shaft upset to being located the horizontal plane in-time, the lower extreme of bearing plate 4 just in time contacts with ground, and the both ends that increase footboard 3 this moment are supported by articulated shaft and bearing plate 4 respectively, make operating personnel can trample on increasing footboard 3, and then maintain the electrical components on cabinet body 1 upper portion and overhaul.

Preferably, the end face of the bearing plate 4 contacting with the ground is provided with anti-slip lines, and the friction force between the end face of the bearing plate 4 and the ground is effectively increased through the anti-slip lines.

In addition, a stopper for attaching the height increasing pedal 3 to the inside of the cabinet door 2 is attached to the inside surface of the cabinet door 2. In this embodiment, the limiting member is a set of elastic blocks 8, and the distance between two elastic blocks 8 is equal to or slightly greater than the width of the height increasing pedal 3. And elastic pieces are arranged on the opposite sides of the two elastic clamping blocks 8 and can stretch along the direction of a connecting line between the two elastic clamping blocks 8. When the heightening pedal 3 is turned upwards until the side surface of the heightening pedal is contacted with the elastic part, the heightening pedal 3 can apply pressure to the elastic part along with the further upward turning of the heightening pedal 3, so that the elastic part is compressed into the elastic clamping block 8, and the heightening pedal 3 can continue to turn upwards; when increasing footboard 3 and cabinet door 2's medial surface and laminating mutually, the side that increases footboard 3 no longer contacts with the elastic component, and the elastic component automatic re-setting this moment stretches out to it is spacing to increasing footboard 3, avoids it to receive the automatic upset downwards of action of gravity. It should be noted that the limiting member may limit the height increasing pedal 3 in other manners.

When an operator needs to overhaul the electrical elements on the upper part of the cabinet body 1, the cabinet body 1 can be opened, the heightening pedal 3 is turned to be positioned in the horizontal plane, the two ends of the heightening pedal 3 are respectively supported by the hinged shaft and the bearing plate 4, the operator can step on the heightening pedal 3, and the operable range of the operator is enlarged.

Referring to fig. 3 to 5, a second embodiment of the present invention is different from the first embodiment in that: the tip of bearing plate 4 in this embodiment is articulated with the tip that increases footboard 3, can make bearing plate 4 and increase footboard 3 be located the coplanar or rather than parallel when need not using and increase footboard 3, avoids bearing plate 4 occupation space great, influences closing of cabinet door 2.

In order to fix the angle between the height increasing pedal 3 and the bearing plate 4 when the height increasing pedal 3 is used, a positioning rod 5 is hinged to the side surface of the height increasing pedal 3, a positioning hole 6 is formed in the free end of the positioning rod 5, and a positioning screw hole 7 is formed in the side surface of the bearing plate 4. When the heightening pedal 3 is perpendicular to the bearing plate 4, the positioning rod 5 can be rotated until the positioning hole 6 is aligned with the positioning screw hole 7, and at the moment, the positioning bolt passes through the positioning hole 6 and then is screwed into the positioning screw hole 7, so that the angle between the heightening pedal 3 and the bearing plate 4 can be fixed.

In addition to the above embodiments, the present invention may have other embodiments; all the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
