Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of scalable canopy of a kind of power transformation box considering power transformation box particular surroundings and demand.
The scalable canopy of this power transformation box, comprises left front support arm, left back support arm, right front support arm, right back support arm, tarpaulin, front cover shell, rear casing, left arm dumpling and right arm dumpling; Described left front support arm and left back support arm and right front support arm and right back support arm are flexibly connected respectively, junction all in establish torsion spring; When not applying external force, described left front support arm and left back support arm and right front support arm and right back support arm launch completely mutually under torsion spring effect; Described left front support arm and right front support arm are connected to front cover shell respectively by left rotary shaft and right spindle, and described left back support arm and right back support arm are flexibly connected left arm dumpling and right arm dumpling respectively, and described left arm dumpling and right arm dumpling are located in the two ends of rear casing respectively; Spool is provided with between left arm dumpling and right arm dumpling; Tarpaulin one end twists on spool, and the other end is connected to inside front cover shell; When tarpaulin is involved in spool completely, left front support arm and left back support arm and right front support arm and right back support arm are folding respectively to be drawn in the closed shell that formed at front cover shell and rear casing; The driving member linked with spool is provided with in rear casing one end.
As preferably: described driving member can connect joystick or motor.
As preferably: be also covered with left case and right case outside described rear casing two ends.
As preferably: be provided with after the two ends of described rear casing for fixing left fixture and right fixture.
As preferably: the torsion spring established in described left front support arm and left back support arm and right front support arm and right back support arm junction is with damping piece.
The beneficial effects of the utility model are: by being the structure of power transformation box particular surroundings and Demand Design specially, when not using at ordinary times, and front cover shell and rear casing form closed shell.Take up room little, do not affect inspection operation, the infringement that avoiding exposes to the weather simultaneously at ordinary times drenches with rain to tarpaulin and internal mechanism.During use, by the torsion spring of left front support arm and left back support arm and right front support arm and right back support arm junction, coordinate left arm dumpling, right arm dumpling, left rotary shaft and right spindle, tarpaulin can be opened voluntarily, with after draw tarpaulin in easily by joystick or motor.This structural strength is high simultaneously, good stability.
Accompanying drawing explanation

Description of reference numerals: left front support arm 1, left back support arm 2, right front support arm 3, right back support arm 4, tarpaulin 5, front cover shell 6, rear casing 7, left arm dumpling 8, right arm dumpling 9, left fixture 10, right fixture 11, spool 12, joystick 13, driving member 14, left case 15, right case 16, left rotary shaft 17, right spindle 18.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.Although the utility model will be described in conjunction with preferred embodiment, should know, not represent the utility model restriction in the described embodiment.On the contrary, the utility model will contain can be included in attached claims limit scope of the present utility model in alternative, modified model and equivalent.
The scalable canopy of power transformation box of the present embodiment, comprises left front support arm 1, left back support arm 2, right front support arm 3, right back support arm 4, tarpaulin 5, front cover shell 6, rear casing 7, left arm dumpling 8 and right arm dumpling 9; Described left front support arm 1 and left back support arm 2 and right front support arm 3 and right back support arm 4 are flexibly connected respectively, junction all in establish torsion spring with damping piece; When not applying external force, described left front support arm 1 and left back support arm 2 and right front support arm 3 and right back support arm 4 launch completely mutually under torsion spring effect; Described left front support arm 1 and right front support arm 3 are connected to front cover shell 6 respectively by left rotary shaft 17 and right spindle 18, described left back support arm 2 and right back support arm 4 are flexibly connected left arm dumpling 8 and right arm dumpling 9 respectively, and described left arm dumpling 8 and right arm dumpling 9 are located in the two ends of rear casing 7 respectively; Spool 12 is provided with between left arm dumpling 8 and right arm dumpling 9; Tarpaulin 5 one end twists on spool 12, and the other end is connected to inside front cover shell 6; When tarpaulin 5 is involved in spool 12 completely, left front support arm 1 and left back support arm 2 and right front support arm 3 and right back support arm 4 are folding respectively to be drawn in the closed shell that formed at front cover shell 6 and rear casing 7; The driving member 14 linked with spool 12 is provided with in rear casing 7 one end.Described driving member 14 can connect joystick 13 or motor.Left case 15 and right case 16 is also covered with outside described rear casing 7 two ends.Be provided with after the two ends of described rear casing 7 for fixing left fixture 10 and right fixture 11.
