Problems solved by technology
[0002] With the improvement of power supply requirements and the reduction of space and manufacturing costs, more and more control and communication instruments are installed on the instrument door of the switch cabinet. The direct result is that there are too many components installed on the instrument door of the switch cabinet. When the instrument door is added with a fixed hinge, it will also cause problems such as door sagging, instrument door deformation, and door locks cannot be used. Seriously, it may even cause the instrument door to fall off during transportation. With the weight of the instrument door drooping, even the instrument The door lock is locked on the cabinet body, and the instrument door lock will be damaged over time

Embodiment Construction
[0020] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail with reference to the accompanying drawings.
[0021] Such as Figure 1~4 As shown, a switchgear instrument door auxiliary positioning device includes a cabinet body 1 and an instrument door 2 hinged on the cabinet body. The cabinet body is provided with a horizontal positioning plane 3 at the inner bottom opposite to the hinged side. The instrument The door is provided with a roller 4 whose central axis is on a horizontal plane under the inner wall opposite to the hinged side, and the roller is supported on the positioning plane when the instrument door is closed.
[0022] In the embodiment of the present invention, the cabinet body is provided with a positioning block at the inner bottom opposite to the hinged side, the positioning block includes a vertical connecting plate 5, and a horizontal angle steel...

The invention relates to an auxiliary positioning apparatus for a switch cabinet instrument door. The auxiliary positioning apparatus comprises a cabinet body and an instrument door hinged on the cabinet body, wherein the cabinet body is provided with a horizontal positioning plane at the internal bottom opposite to the hinged side; the instrument door is provided with a rolling wheel, the central axis of which is positioned on the horizontal surface, below the inner wall opposite to the hinged side; and the rolling wheel supports the positioning plane when the instrument door is closed. The auxiliary positioning apparatus for the switch cabinet instrument door is simple in structure; and when the instrument door is closed, the rolling wheel supports the positioning plane, so that the hinge load at the hinged end of the instrument door can be scattered, and failures of overload deformation and the like of the instrument door can be relieved.
Description
technical field [0001] The invention relates to an auxiliary positioning device for an instrument door of a switch cabinet and a using method thereof. Background technique [0002] With the improvement of power supply requirements and the reduction of space and manufacturing costs, more and more control and communication instruments are installed on the instrument door of the switch cabinet. The direct result is that there are too many components installed on the instrument door of the switch cabinet. When the instrument door is added with a fixed hinge, it will also cause problems such as door sagging, instrument door deformation, and door locks cannot be used. Seriously, it may even cause the instrument door to fall off during transportation. With the weight of the instrument door drooping, even the instrument The door lock is locked on the cabinet body, and the instrument door lock will be damaged over time. Contents of the invention [0003] In view of the deficiencie...
