Help and draw subassembly 3 to constitute by decompression piece 4, track board 5, T-shaped piece 6 and

backup pad

7, 2 bottom four corners of unit drawer have all been opened mounting groove 8, decompression piece 4 is equipped with four, and install respectively with four mounting grooves 8 in, track board 5 and T-shaped piece 6 all are equipped with two, and two track boards 5 fix respectively on 1 both sides inner wall of cubical switchboard casing, T-shaped piece 6 is equipped with two, and two T-shaped pieces 6 fix respectively on 2 both sides outer walls of unit drawer, two T-shaped pieces 6 respectively with two 5 inner wall sliding connection of track board, backup pad 7 is located decompression piece 4 bottom, and backup pad 7 both sides are fixed with 1 both sides inner wall of cubical switchboard casing, make 2 pulls of unit drawer and impel more easily stable through helping drawing subassembly 3.

Decompression piece 4 comprises bracing piece 9, decompression post 10, spring 11, limiting plate 12 and C

shape sliding block

13, 9 one end of bracing piece is fixed with 8 bottoms in mounting groove, and the other end slides and runs through decompression post 10 tops to it is fixed with limiting plate 12, spring 11 is located decompression post 10, and the 11 both ends of spring are fixed with limiting plate 12 and decompression post 10 bottom inner wall respectively, C shape sliding block 13 is fixed in decompression post 10 bottom, and is equipped with gyro wheel 14 bottom C shape sliding block 13, gyro wheel 14 rotates with C shape sliding block 13 bottom both sides through the round pin axle and is connected, offsets the part total amount of unit drawer 2 totality through decompression piece 4 to avoid the direct contact of unit drawer 2 and backup pad 7.

The specific implementation mode is as follows: when the unit drawer 2 is pushed in and pulled out, the handle which is held at the outer side of the unit drawer 2 rotates, the unit drawer is pulled out after being unlocked, because the unit drawer 2 and the electrical components in the unit drawer 2 have a certain weight, a downward gravity is generated to drive the support rod 9 to move downward, at this time, the spring 11 is extruded and deformed, and elastic deformation generates an upward elastic force, so that the T-shaped blocks 6 fixed at the two sides of the unit drawer 2 are not contacted with the inner wall of the bottom of the track plate 5 or are only contacted with the inner wall of the track plate 5 without extrusion, thereby effectively avoiding the generation of large friction resistance due to the contact between the T-shaped blocks 6 fixed at the two ends of the unit drawer 2 and the inner wall of the track plate 5, ensuring that the unit drawer 2 is not pushed smoothly, and the rolling wheels 14 arranged at the bottom of the C-shaped sliding block 13 are in sliding contact with the limiting rails 15, so that sliding friction is changed into rolling friction, friction force is effectively reduced, and the unit drawer 2 is convenient to push.
