Embodiment 3
As shown in Figure 1, the present embodiment shelter lifting mechanism is as the further improvement of embodiment 2, described the first sprocket wheel 3a is arranged at the top of sleeve 1, described the second sprocket wheel 3b is arranged at the first sprocket wheel 3a below, on the lateral wall of sleeve 1, sidewall at sleeve 1 is provided with the chain entrance 6 that penetrates for chain 4, after described chain 4 is walked around the second sprocket wheel 3b, penetrated to the inside of sleeve 1 by chain entrance 6, and lay out to the outside of sleeve 1 from the opening that is arranged at sleeve 1 top after walking around the first sprocket wheel 3a, and cooperate tensioning to form chain ring with drive sprocket 5, adopt in such a way, when realizing lifting movable branching rod 2, be conducive to structural arrangement, chain 4 be arranged at respectively sleeve 1 in, outer both sides are easy entanglement and mutually interfering not also.
All the other structures see also embodiment 2.
As shown in the figure, the present embodiment shelter lifting mechanism is as the further improvement of embodiment 2, described drive sprocket 5 is arranged on the cabin body 7, between cabin body 7 and sleeve 1, be provided with two connecting rods 8, be in the present embodiment, connecting rod 8 comprises first connecting rod 8a and second connecting rod 8b, the two ends of first connecting rod 8a and second connecting rod 8b are hinged with cabin body 7 and sleeve 1 respectively, described first connecting rod 8a and drive sprocket 5 coaxial being articulated on the cabin body 7, described cabin body 7, sleeve 1 and connecting rod 8 are formed in the parallel-crank mechanism of perpendicular motion.Two connecting rods 8 are positioned on the same vertical direction with the hinge point of cabin body 7, two connecting rods 8 are positioned on the same vertical direction with the hinge point of sleeve 1, and two connecting rods 8 equate with the spacing of sleeve 1 hinge point with spacing and two connecting rods 8 of the hinge point of cabin body 7, formation take cabin body 7 as frame, sleeve 1 is rocking bar and the parallel-crank mechanism take two connecting rods 8 as side link, this parallel-crank mechanism moves in perpendicular.When connecting rod 8 when the hinge point of itself and cabin body 7 is rotated, sleeve 1 moves along level, vertical direction simultaneously, that is: expand outwardly when sleeve 1 is transferred, in existing structure: horizontal direction is compared by the mode that the hinge leaf formula is taken down the exhibits, vertical direction is taken down the exhibits by sleeve 1 and movable branching rod 2 length adjustment, can the realization level by driving parallel-crank mechanism, vertically both direction takes down the exhibits synchronously, significantly improve the efficient of taking down the exhibits, be convenient to the rapid deployment of cabin body 7.
Shelter lifting mechanism in the present embodiment from folded state when launching course of action such as Fig. 8 to shown in Figure 10, at first see also Fig. 8, when the shelter lifting mechanism was packed up, the relative height between movable branching rod 2 bottoms and the cabin body 7 is poor to be L1;
When launching parallel-crank mechanism, the height of movable branching rod 2 bottoms reduces along with the decline of sleeve 1 height, and this process operation only needs the time of 1s～2s, and the diff-H before movable branching rod 2 bottom level and the reduction is L2 simultaneously; This part action is consuming time extremely short and to fall journey larger, has significantly improved the lifting efficient of shelter, and the structure after the expansion as shown in Figure 9;
Parallel-crank mechanism be expanded to preset posture and firm after, drive chain 4 liftings by drive sprocket 5, at this moment, movable branching rod 2 is in sleeve 1 inner relatively lifting, structure before and after the lifting of this step as shown in figure 10, the diff-H between this step movable branching rod 2 and the cabin body 7 is L3.
As the equivalent embodiment of the present embodiment, the quantity of connecting rod 8 can be three or more, and servo-actuated as follower lever, increases the stability of structure, just repeats no more at this.
Further setting forth the present embodiment below in conjunction with Figure 11 and Figure 12, to transfer efficient high, fireballing improvement structure, see also Figure 11, before parallel-crank mechanism launches, be positioned at the movable branching rod 2 bottoms height overhead of sleeve 1, required trip distance is L4 when namely unloading, the mode that the stroke of whole L4 length all needs to regulate movable branching rod 2 bottom positions with straight line driving mechanism in the prior art is compared, in the present embodiment, by launching parallel-crank mechanism, in the process of launching, the bottom of movable branching rod 2 already follow sleeve 1 synchronization lifting length be the stroke of L2, and this part stroke launches only to need about 1 second, efficient is high, remaining, the stroke L5=L4-L2 that needs the dependence straight line driving mechanism to regulate, the lift rising or falling speed that this part relies on straight line driving mechanism to finish is relatively slow, but because the stroke of this part reduces, it is consuming time also lower.
All the other structures see also embodiment 2.
As shown in Figure 2, the present embodiment shelter lifting mechanism is provided with strut 9 as the further improvement of embodiment 2 between described cabin body 7 and sleeve 1, and the fixed end of described strut 9 and sleeve 1 are hinged, the movable end of described strut 9 and 8 dismantled and assembled connections of connecting rod.When the shelter lifting mechanism is expanded to preset posture, movable end and the connecting rod 8 of strut 9 is fixed, play the effect of the relative motion between restriction sleeve 1 and the cabin body 7 by strut 9, dismantled and assembled connection the in the present embodiment between the movable end of strut 9 and the connecting rod 8, what adopt is the mode of common pin joint, namely by pin-and-hole and corresponding latch are set, realization strut 9 is connected and decomposition with connecting rod 8.Need to prove, the strut 9 in the present embodiment can adopt diagonal brace or oblique pull dual mode to realize, just repeats no more at this.
All the other structures see also embodiment 2.
As shown in Figure 3 and Figure 4, the present embodiment shelter lifting mechanism is as the movable end and the connecting rod 8 dismantled and assembled a kind of preferred implementations that are connected of strut 9 among the embodiment 2, the movable end of described strut 9 is wedge shape, the side of connecting rod 8 is provided be used to the bayonet socket 10 that holds strut 9 movable ends, when the movable end of strut 9 placed bayonet socket 10 inside, described strut 9 was mutually vertical with connecting rod 8.When parallel-crank mechanism need to lock, the clamping wall cassette in strut 9 and the bayonet socket 10 cooperated, thereby has limited the movable end of strut 9 at the degree of freedom of bayonet socket 10 internal activities, and so that whole parallel-crank mechanism lock.The purpose of in the present embodiment the movable end of strut 9 being arranged to wedge shape is to be convenient to strut 9 to be fed through bayonet socket 10 inside, adopt the strut 9 of wedge shape, before parallel-crank mechanism moves to default clamping attitude, can be inserted in the bayonet socket 10 by tapered end, dimensional restriction is little, in all the other embodiments, the mode in round end or flat pattern cross section also can be adopted in the end of strut 9, just repeats no more at this.
Adopt the structure of the present embodiment, with respect to as adopting the pin pin joint to form the mode of dead bar among the embodiment 5, only need that in disassembly process strut 9 is overlapped on connecting rod 8 and get final product, rear insertion pin need not to hold position, not only easy to operate, and be difficult for strand and hinder operating personal, safety performance is better.
