On the upper box, the support cylinder other end is connected with the torque adjusting apparatus；It also includes and is fixed on the lower box
With the hinge of upper box, the support cylinder drives the upper box using the hinge to be axial by the torque adjusting apparatus
It is turned on and off.
Further, the torque adjusting apparatus includes handle and adjustment plate, and described adjustment plate one end is connected to upper box
On, the other end is connected on the upper box with the support cylinder output axis connection, the handle and drives the adjustment plate
It is swung with locating shaft two to be axial.
Further, connecting rod is additionally provided between the handle and adjustment plate, the handle is driven by the connecting rod
The adjustment plate swings.
Further, the adjustment plate left and right ends are equipped with the limited block of limitation adjustment plate amplitude of fluctuation.
Further, the opening of the lower box and upper box is that beveled angle of inclination A is between 17-21 degree, excellent
Select 19 degree.
Beneficial effect, hinge form fulcrum, and the output shaft of cylinder and the junction of adjustment plate is supported to form stress point, branch
Point is passed through air pressure with the distance between stress point formation torque, support cylinder, and the output shaft of support cylinder is made to generate one upwards
Power, adjustment pressure valve change air pressure size can change output shaft generate power size.
When needing to open upper box, handle is pulled upwards, and handle, to rotate axially upwards, passes through connection with locating shaft one
Bar drives adjustment plate to be swung to the left to be axial with locating shaft two, makes torque elongated, so as to easily open upper box, when needing to close
During upper box, handle is pulled downwards, and handle drives adjustment plate to swing to the right, torque is made to shorten, so as to easily close upper box, most
Laborsaving opening and closing is realized eventually.
Description of the drawings
Fig. 1, a kind of laborsaving opening and closing shielded box opening stereogram.
Fig. 2, a kind of laborsaving opening and closing shielded box closed state side view.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
Referring to Fig. 1, in the utility model embodiment, a kind of laborsaving opening and closing shielded box, including lower box 1,2 and of upper box
Pedestal 3, the lower box 1 and upper box 2, which are closed, forms a complete cavity；Also connected comprising one end on the lower box 1
Support cylinder 4；Also comprising the torque adjusting apparatus 5 being connected on the upper box 2, support 4 other end of cylinder and institute
State torque adjusting apparatus connection 5；Also comprising the hinge 6 for being fixed on the lower box 1 and upper box 2, the support cylinder 4 passes through
The torque adjusting apparatus 5 drives the upper box 2 to be turned on and off with the hinge 6 to be axial.
Further, the torque adjusting apparatus 5 includes handle 51 and adjustment plate 53, and described 53 one end of adjustment plate is connected to
On upper box 2, the other end exports axis connection with the support cylinder 4, and the handle 51 is connected on the upper box 2 and drives
The adjustment plate 53 is swung with locating shaft 2 531 to be axial.
Further, connecting rod 52 is additionally provided between the handle 51 and adjustment plate 53, the handle 51 passes through the company
Extension bar 52 drives the adjustment plate 53 to swing.
Further, 53 left and right ends of adjustment plate are equipped with the limited block 54 of limitation 53 amplitude of fluctuation of adjustment plate, /V
Block 54 can be it is fixed can also be adjustable.
