Preferably, being also coated with profit on the outer surface of the lead screw 26 to improve the mobile smooth degree of connecting sleeve 29 Lubrication prescription reduces the frictional force between connecting sleeve 29 and lead screw 26 by lubricant, so that it is mobile to improve connecting sleeve 29 Smooth degree.

Preferably, the making material of the sucker 27 is rubber, due to rubber in order to enhance the firmness of the absorption of sucker 27 The material of glue is more soft, so that the gap between sucker 27 and ground is reduced, to enhance the secured of the absorption of sucker 27 Degree.

When device failure inside power distribution cabinet is needed replacing or detected, technical staff only needs by pressing Clip assembly is pressed, so that clip assembly and telescopic component be made to be detached from, later under the action of telescopic component, pushes track 4 to remote Direction from mounting plate 13 is mobile, to make the device being mounted on track 4 that can remove between wire casing, to improve technology The convenient degree of personnel's replacement or detection device, improves the practicability of electrical cabinet, after device, which is replaced, to be completed, technical staff It only needs to push track, to make two telescopic components connect with two clip assemblies respectively, to device be put back to original Position reduces the space occupancy rate of device, and technical staff sends a signal to PLC by remote equipment, and PLC receives control letter After number, PLC brings into operation according to internal processes, under the control of PLC, is drivingly connected casing 29 by driving assembly and goes up and down, Fixed link 28 is driven to go up and down under the action of connecting sleeve 29 later, to pull the middle part of sucker 27 or more by fixed link 28 It is mobile, power distribution cabinet is adsorbed on the ground by sucker later, to improve the firmness of power distribution cabinet installation.

Compared with prior art, in the high power distribution cabinet of the stability convenient for safeguarding, by maintenance agencies, make track 4 can With mobile to the direction far from mounting plate 13, to make track 4 remove between two wire casings, to reduce wire casing to device The obstruction of replacement improves the efficiency of device replacement, and compared with existing mechanism, the mechanism structure is ingenious, drives without motor, drop The low power consumption of power distribution cabinet, moreover, by strengthening mechanism, improve connected between power distribution cabinet and ground it is secured Degree, to improve the stability of power distribution cabinet, compared with existing mechanism, which is driven by lead screw 26, is not required to motor 25 To continue to provide power to keep position of the connecting sleeve 29 on lead screw 26, to reduce the load of motor 25.

Taking the above-mentioned ideal embodiment according to the present invention as inspiration, through the above description, relevant staff is complete Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention Property range is not limited to the contents of the specification, it is necessary to which the technical scope thereof is determined according to the scope of the claim.
