Summary of the invention
In view of this, the object of this invention is to provide and a kind ofly can be used in rural area, post-disaster reconstruction district and fall behind remote area, this suspension gear structure is simple, manufacture difficulty is little, and is easy to dismounting, and easily operates, applicable crowd is comparatively wide, mechanical suspension device simultaneously easy to maintenance;
Mechanical suspension device of the present invention, comprises pilot bar, hanger bar and locking block; Described hanger bar is longitudinally snug fit at described pilot bar; Described locking block flexibly connects in pilot bar and is provided with through hole that hanger bar is passed and this through-hole diameter is greater than described hanger bar external diameter;
Further, stay cord is connected with between described locking block and hanger bar;
Further, described hanger bar lower end is provided with hook;
Further, described pilot bar and hanger bar outer wall are equipped with screw thread;
Further, described pilot bar lower end is provided with bottom fold section orthogonal with it, and described hanger bar upper end is provided with mutual vertically disposed top fold section with it; Described top fold section is provided with pilot bar via hole, and described bottom fold section is provided with hanger bar via hole;
Further, described through hole is provided with negative thread.
The invention has the beneficial effects as follows: mechanical suspension device of the present invention, the positions such as top ceiling can be fixed in pilot bar upper end, longitudinally bearing fit between hanger bar and pilot bar, therefore, can by the height of hanger bar relative to the slide control hanger bar of pilot bar, after hanger bar is adjusted to correct position, locking block is made to rely on own wt to deflect under the traction of pilot bar, the through-hole wall of locking block and hanger bar contact with each other and produce the friction force that hanger bar and pilot bar are locked mutually, structure of the present invention is simple, manufacture difficulty is little, and be easy to dismounting, and easily operate, applicable crowd is wider, simultaneously easy to maintenance.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the force analysis schematic diagram of hanger bar of the present invention;
Fig. 3 is the force analysis schematic diagram of locking block of the present invention.
Detailed description of the invention
Fig. 1 is structural representation of the present invention, as shown in the figure, the mechanical suspension device of the present embodiment, comprises pilot bar 1, hanger bar 2 and locking block 3, described hanger bar 2 is longitudinally snug fit at described pilot bar 1, described locking block 3 flexibly connects in pilot bar 1 and is provided with through hole that hanger bar 2 is passed and this through-hole diameter is greater than described hanger bar 2 external diameter, longitudinally bearing fit between hanger bar 2 and pilot bar 1, therefore, can by the height of hanger bar 2 relative to the slide control hanger bar 2 of pilot bar 1, after hanger bar 2 is adjusted to correct position, make locking block 3 under the traction of pilot bar 1, rely on own wt to deflect, the through-hole wall of locking block 3 and hanger bar 2 contact with each other and produce the friction force that hanger bar 2 is locked mutually with pilot bar 1, structure of the present invention is simple, manufacture difficulty is little, and be easy to dismounting, and easily operate, applicable crowd is wider, simultaneously easy to maintenance, as shown in Figure 2, this suspension gear is when hanging weight, hanger bar 2 is subject to friction force and gravity along y-axis, the condition of mechanical self-latching is formed between hanger bar 2 and locking block 3, strict guarantee hanger bar 2 can not occur in y-axis direction automatically to glide, and the weight of constant weight can be supported, safe ready .X direction of principal axis, locking block 3 and hanger bar 2 can force simplified be two-point contact, hanger bar 2 is subject to positive pressure and to the right respectively left, stablizing of assurance device subrange.As Fig. 3, according to hanger bar 2 contact with locking block 3, the force analysis that hanger bar 2 can simplify is: Y direction, be upwards subject to locking block 3 to two friction force f

In the present embodiment, be connected with stay cord 4 between described locking block 3 and hanger bar 2, when needs adjustment hanger bar 2 height, can pull stay cord 4, what make locking block 3 deflect to remove between hanger bar 2 with pilot bar 1 is relative fixing.
In the present embodiment, described hanger bar 2 lower end is provided with hook, and be convenient to catch on the article needing to hang, this hook is by being formed after hanger bar 2 bending, and therefore, its intensity is higher, can improve the load-carrying capacity of hook.
In the present embodiment, described pilot bar 1 is equipped with screw thread with hanger bar 2 outer wall, screw thread can increase substantially the friction coefficient of pilot bar 1 and hanger bar 2 outer wall, owing to being fixedly realized by the friction force between the through hole of locking block 3 and hanger bar 2 between hanger bar 2 and pilot bar 1, therefore, the friction coefficient improving hanger bar 2 surface effectively can improve the hanging capacity of this suspension gear.
In the present embodiment, described pilot bar 1 lower end is provided with bottom fold section orthogonal with it, and described hanger bar 2 upper end is provided with mutual vertically disposed top fold section with it; Described top fold section is provided with pilot bar 1 via hole, described bottom fold section is provided with hanger bar 2 via hole, this arrangement can make pilot bar 1 and hanger bar 2 keeping parallelism arrange, pilot bar 1 via hole and hanger bar 2 via hole are convenient to lubricating maintenance, except guiding, keep the stable of whole device simultaneously, complete the suspension of arbitrary height.
In the present embodiment, described through hole is provided with negative thread, and the negative thread in the outside thread on hanger bar 2 surface and through hole contacts with each other, thus guarantees to form self-locking.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
