The suspender of the convertible state of the utility model, comprise two straight beams, on every straight beam, be at least symmetrically arranged with a pair of hoist cable point of connection, described two straight beams stack up and down and the centre of the two hinged by rotating shaft, on upper and lower two straight beams, be respectively equipped with upper and lower locating plate, on described upper and lower locating plate, be respectively equipped with a plurality of knock holees, when upper and lower two straight beams rotate when setting angle around the shaft, corresponding knock hole on upper and lower locating plate overlaps, and barrel bolt can be fixed together two locatings plate through knock hole.

The suspender of the convertible state of the utility model, wherein said upper locating plate is horizontally fixed on the bottom of straight beam side, and described lower locating plate is horizontally fixed on the top of lower straight beam side.

The suspender of the convertible state of the utility model, between wherein said upper locating plate and upper straight beam side, be also connected with respectively reinforcement riser between lower locating plate and lower straight beam side.

The suspender of the convertible state of the utility model, arranges respectively two upper and lower locatings plate on each side of wherein said upper and lower straight beam, the part that described upper and lower locating plate is arranged in upper and lower straight beam is located at the both sides of rotating shaft.

The suspender of the convertible state of the utility model, wherein also comprises two hangers, and described two hangers are detachably connected on part in lower straight beam and are located at rotating shaft both sides.

The suspender of the convertible state of the utility model, the wide two ends, middle part of wherein said upper and lower straight beam are narrow.

The suspender of the convertible state of the utility model, is symmetrically arranged with respectively four pairs of hoist cable point of connection on wherein said upper and lower straight beam.

The suspender difference from prior art of the convertible state of the utility model is that the suspender of the convertible state of the utility model arranges that two straight beams stack up and down and is hinged by rotating shaft, make its between the two angle rotatably regulate, simultaneously upper, on lower two straight beams, arrange respectively, lower locating plate, on, on lower locating plate, be respectively equipped with a plurality of knock holees, during use, by upper, in lower two straight beams one or two rotates to around the shaft and sets angle as 90 ° of (also other angles, the angle orientation that a plurality of knock holees are corresponding different), on, corresponding knock hole on lower locating plate overlaps, barrel bolt are just fixed together two locatings plate through knock hole, make, lower two straight beams keep fixed angle to lift, while not using, remove the bolt between knock hole, by upper, one or two in lower two straight beams is rotated into around the shaft, " one " font of lower coincidence, so greatly reduce to transport storage space.

Below in conjunction with accompanying drawing, the suspender of convertible state of the present utility model is described further.

Accompanying drawing explanation

Fig. 1 is the structural representation of the suspender of the convertible state of the utility model;

Fig. 2 is the partial enlarged drawing at A place in Fig. 1.

The specific embodiment

As shown in Figure 1, the suspender of the convertible state of present embodiment comprises two

straight beams

10,20, on every straight beam, be symmetrically arranged with four pairs of hoist cable point of connection 30, in conjunction with figure, can see, two

straight beams

10,20 stack up and down, the centre of the two is hinged by rotating shaft 40, also comprises that two hangers, 60, two hangers 60 are bolted part in lower straight beam 20 and are located at rotating shaft 40 both sides.

On upper and lower two

straight beams

10,20, be respectively equipped with upper and lower locating plate 11,21, wherein go up locating plate 11 and be horizontally fixed on the bottom of straight beam 10 sides, lower locating plate 21 is horizontally fixed on the top of lower straight beam 20 sides, two upper and lower locatings plate 11,21 are set respectively on each side of upper and lower

straight beam

10,20, the part that is arranged in upper and lower

straight beam

10,20 is located at the both sides of rotating shaft 40, on upper and lower locating plate 11,21, is respectively equipped with a plurality of knock holees.

During use, by one in upper and lower two

straight beams

10,20 or two 40 rotations around the shaft to setting angle, it is 90 ° of right angles that present embodiment is set angle, be that upper and lower straight beam is " ten " word beam, corresponding knock hole on upper and lower locating plate 11,21 overlaps, barrel bolt are fixed together two locatings plate through knock hole, make upper and lower straight beam keep fixing 90 ° of angles and carry out lifting operation.

After having lifted, while not using, by the disassembling bolts on knock hole, the disassembling bolts between hanger and lower straight beam, takes hanger away, by one or two in upper and lower two straight beams " one " font that is rotated into around the shaft upper and lower coincidence.

Further, as shown in Figure 2, between upper locating plate 11 and upper straight beam 10 sides, between lower locating plate 21 and lower straight beam 20 sides, arrange respectively and strengthen riser 50 and be connected, the solidness between locating plate and straight beam is improved.

The wide two ends, middle part that upper and lower

straight beam

10,20 is set are narrow, strengthen bearing the rigidity of the centre that moment of flexure is large, and adopt less material for bearing the two ends that moment of flexure is little, guaranteed rigidity requirement, again can expendable weight.

On upper and lower

straight beam

10,20, be symmetrical arranged respectively four pairs of hoist cable point of connection 30, can adapt to the suspended object of lifting different-diameter size.

The suspender of the convertible state of the utility model, upper and lower straight beam angle is not limited to right angle, can be also other angles, as long as set corresponding knock hole.

Above-described embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model, all should fall in the definite protection domain of the utility model claims.
