Universal portable safety protection combined device for high-low voltage metering box

Abstract

The invention relates to the technical field of metering boxes, and especially relates to a universal portable safety protection combination device for a high-low pressure metering box. The device comprises a protection box, the protection box is rotatably connected with double-thread screw rods, each double-thread screw rod is in threaded connection with a lifting moving block, and each lifting connecting plate is rotatably connected with a lifting fixed block. Lifting plates are fixedly arranged on the multiple lifting fixing blocks, transverse buffer bases are fixedly arranged on containing boxes, longitudinal buffer bases are fixedly arranged on the transverse buffer rods, transverse L-shaped clamping blocks are slidably connected to the first long through grooves, and first trapezoidal sliding bases are fixedly arranged on the transverse L-shaped clamping blocks; and longitudinal L-shaped clamping blocks are slidably connected to the second long through sliding grooves correspondingly, and second trapezoidal sliding seats are fixedly arranged on the longitudinal L-shaped clamping blocks. On the basis of a common combined device, a multi-directional buffering, moving and fixing device is arranged, so that the protection effect, convenience and stability of the high-low pressure metering box are improved.

Description

technical field [0001] The invention relates to the technical field of metering boxes, in particular to a universal portable safety protection combination device for high and low voltage metering boxes. Background technique [0002] The high and low voltage metering box is a combination of combined transformers, measuring instruments and meters. The metering box is the whole of metering instruments and auxiliary equipment necessary for metering electric energy, including electric energy meters, voltage for metering, current transformers and their secondary circuits, electric energy metering screens, cabinets, boxes, etc. The metering box can be installed suspended or floor-mounted. [0003] At present, when the high and low voltage metering boxes are transported, the protection effect on the high and low voltage metering boxes is usually not ideal, and the influence of the road environment may easily lead to damage to the surface of the high and low voltage metering boxes, ...
