The device 20 of thing blind patch gravitational moment curve characteristic is hung in adjusting provided by the present invention, and its course of work is as follows.
Open or close in process hanging thing blind patch 10, counterweight 3 is under the acting in conjunction of self gravitation and elastic device 6 elastic force, shift gently between the free end 11 of cover plate 10 and hinged end 12 along slide rail 4, thereby change the gravitational moment curve of cover plate 10, play assisting in opening and the effect of closing cover plate 10.And hanging after thing bore closure, preventing that nose phenomenon from appearring in cover plate 10.
Particularly, in the time that cover plate 10 is closed, counterweight 3 is positioned at free end 11 1 sides of cover plate 10, and the gravity of counterweight 3 self is equivalent to apply a downward power at the free end 11 of cover plate 10, also be equivalent to the center of gravity of cover plate 10 to move to free end 11 1 lateral deviations, thereby avoided the perk of free end 11.
In cover plate 10 opening procedures, along with the opening angle of cover plate 10 increases gradually, the elastic force that is greater than frictional force and elastic device 6 when the weight component of counterweight 3 on slide rail 4 is axial is done the used time, hinged end 12 directions that counterweight 3 starts along slide rail 4 to cover plate 10 move, thereby play the effect of shifting cover plate 10 centers of gravity, because the center of gravity of cover plate 10 is offset to hinged end 12, play the effect that auxiliary cover plate 10 is opened like this.Due to the elastic force effect of elastic device 6, play a part and offset the effect of counterweight 3 weight components, not the energy release of moment thereby make the whole folding process of counterweight 3, but comparatively mild.In the time that cover plate 10 is opened completely, counterweight 3 is positioned at the position of its most close cover plate 10 hinged ends 12 on slide rail 4, and at this moment the gravity of counterweight 3 makes the decentralization of cover plate 10 to minimum, plays the firm effect of cover plate 10 upright state that keeps.
Accordingly, in the time that cover plate 10 is closed, along with falling gradually of cover plate 10, elastic device 6 is under the effect of elastic force, promoting counterweight 3 moves to the free end 11 of cover plate 10 gradually, thereby the center of gravity of cover plate 10 is offset to free end 11, has changed the gravitational moment curve that hangs thing blind patch 10, cover plate 10 is more successfully closed.
For the radially angled embodiment of slide rail 4 and cover plate 10, the process that cover plate 10 is opened is as follows: cover plate 10 is under the effect of staring torque, open gradually, before 4 one-tenth levels of slide rail, counterweight 3 is all positioned near the position of cover plate 10 free ends 11 and keeps motionless under the acting in conjunction of self gravitation component and elastic device 6.In the time of 4 one-tenth levels of slide rail, as shown in Figure 5, now the gravity of counterweight 3 is 0 along the component of slide rail 4 directions.Along with further opening of cover plate 10, when slide rail 4 is crossed level while tilting to the hinged end 12 of cover plate 10, counterweight 3 produces the component moving to the hinged end 12 of cover plate 10 along the direction of slide rail 4, and this component is along with the increase at slide rail 4 angles of inclination strengthens gradually.In the time that the weight component of counterweight 3 is greater than the elastic force of elastic device 6, counterweight 3 starts to slide to the hinged end 12 of cover plate 10, as shown in Figure 6.Due to the inhibition of spring assembly 6, although the weight component speedup of counterweight 3 is very fast, can abrupt release energy and clash into, thus opening of auxiliary cover plate 10 gently.In the time that cover plate 10 is opened completely, counterweight 3 reaches maximum value along the downward power of slide rail 4, thereby is positioned at the position of the most close cover plate 10 hinged ends 12, makes the decentralization of cover plate 10 to minimum, plays the firm effect of cover plate 10 upright state that keeps, as shown in Figure 7.
When cover plate 10 is closed, first, under the effect of staring torque, the angle that cover plate 10 is opened reduces gradually, and the angle of inclination of slide rail 4 also reduces gradually until level.In the time that slide rail 4 is crossed level, counterweight 3 self produces the power along slide rail 4 to free end 11 directions, promotes counterweight 3 together with the elastic force of this weight component and elastic device 6 to glide, thereby makes cover plate 10 be easier to close.In the time that cover plate 10 is closed completely, again because slide rail 4 has angle of inclination, make counterweight 3 except being subject to the thrust of elastic device 6, be also subject to the effect of weight component, thereby can be more firmly positioned at the free end 11 of cover plate 10, prevent the perk of free end 11.
In the present invention, the weight of counterweight 3 is selected, and the selection of elastic device 6, determines according to the concrete condition of hanging thing hole.Consider the factors such as the structure, material, weight, staring torque of cover plate 10, select suitable balance weight and suitable elastic device 6.
