The specific embodiment
as shown in Fig. 1 ~ Fig. 5, the torsion-bar spring booster for plate type extended square cabin of the present embodiment comprises torsion-bar spring 2, the first torsion-bar spring seat 3 and the second torsion-bar spring seat 4.Wherein: the first torsion-bar spring seat 3 and the second torsion-bar spring seat 4 are platy structure, the first torsion-bar spring seat 3 is fixed on the fixed base plate 1 of expanded shelter by 20 M6 sunk screws, the second torsion-bar spring seat 4 is fixed on the telescopic backboard 5 of expanded shelter by 20 M6 sunk screws, one end of torsion-bar spring 2 is fixed on the first torsion-bar spring seat 3, and the other end is fixed on the second torsion-bar spring seat 4.That is: one end of torsion-bar spring 2 is fixed on fixed base plate 1 by the first torsion-bar spring seat 3, and the other end is fixed on telescopic backboard 5 by the second torsion-bar spring seat 4.During enforcement, telescopic backboard 5 be take torsion-bar spring 2 and is carried out rotary movement as trip shaft.
shown in Figure 12, when telescopic backboard 5 in shown in Fig. 2 close up state time (0 °), torsion-bar spring 2 is in relaxation state, essentially no elastic torque, the agravic moment of torsion of telescopic backboard 5, as telescopic backboard 5 being deployed into the extended mode as shown in Fig. 3 (90 °), the axial line of torsion-bar spring 2 of just telescopic backboard 5 need to being take overturns downwards as trip shaft, now, the the second torsion-bar spring seat 4 being fixed on telescopic backboard 5 overturns with telescopic backboard 5, the the first torsion-bar spring seat 3 coordinating with torsion-bar spring 2 other ends is fixed on fixed base plate 1 and does not rotate, thereby the two ends in torsion-bar spring 2 produce torsional displacement, torsion-bar spring produces reaction torque with the gravity torque of opposing telescopic backboard 5, thereby produce power-assisted effect, remaining telescopic backboard gravity just can easily be overturn by manpower.
as shown in Figure 5, in order to guarantee that telescopic backboard 5 is in correct position and the stability in when upset, this example between torsion-bar spring 2 and the fixed base plate 1 and position that is all connected with hinge plate 6(hinge plate between torsion-bar spring 2 and telescopic backboard 5 between the first and second torsion-bar spring seats).
concrete matching relationship between above-mentioned torsion-bar spring 2 and first, second torsion-bar spring seat can be with reference to shown in Fig. 6 ~ Figure 10: described torsion-bar spring 2 is elongated rod-shaped body, octagon structure is all made at its two ends, the cross section that is torsion-bar spring both ends is octagon (certainly also can adopt the regular polygons such as regular pentagon, regular hexagon, positive heptagon), on described the first torsion-bar spring seat 3 and the second torsion-bar spring seat 4, be all shaped with the octagon endoporus matching with torsion-bar spring 2 ends, during assembling, insert in described octagon endoporus the end of torsion-bar spring 2.Torsion-bar spring 2 adopts oil hardening alloy spring wire, case hardness Rc48-53; For reduce allowance and utilize original material as far as possible, only its two ends are processed in right amount, reach the object coordinating with torsion-bar spring seat.The first torsion-bar spring seat 3 and the second torsion-bar spring seat 4 are platy structure.
as shown in figure 11, this hinge plate 6 adopts drawing aluminium extruded sections to make to the concrete structure of above-mentioned hinge plate 6, and its one end is manufactured with a circular inner hole 6-1.During assembling, one end of hinge plate 6 is set on rotationally in torsion-bar spring 2 and (is take torsion-bar spring as hinge axis) by this circular inner hole 6-1, and the other end is fixed on base plate (fixed base plate or telescopic backboard) by sunk screw.
certainly, we also can be according to the size of shelter, is chosen in one or more sets torsion-bar spring boosters are installed on shelter.By Fig. 4, be not difficult to find out, the present embodiment has just been installed two cover described torsion-bar spring boosters (being arranged in juxtaposition) between fixed base plate and telescopic backboard.
the assembling process of the present embodiment is:
1) one end of torsion-bar spring 2 is pressed into the first torsion-bar spring seat 3;
2) in torsion-bar spring 2, put two (being generally two) hinge plates 6;
3) other end of torsion-bar spring 2 is pressed into the second torsion-bar spring seat 4;
4) a slice hinge plate 6 being enclosed within torsion-bar spring 2 is installed on telescopic backboard 5;
5) the second torsion-bar spring seat 4 is installed on telescopic backboard 5;
6) telescopic backboard 5 is erect and moved on fixed base plate 1;
7) another sheet hinge plate 6 being enclosed within torsion-bar spring 2 is installed on fixed base plate 1;
8) the first torsion-bar spring seat 3 is installed on fixed base plate 1.
after installing, after telescopic backboard 5 is turned down, torsion bar produces torsion and acts on telescopic backboard, and the elastic torque that torsion bar is produced when reversing is offset the gravity torque of telescopic backboard when upset, plays power-assisted effect.
certainly, above-described embodiment is only explanation technical conceive of the present invention and feature, and its object is to allow people can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalent transformation or modification that according to the present invention, the Spirit Essence of main technical schemes is done, within all should being encompassed in protection scope of the present invention.
