A load decomposing device comprises a circular ring structure, wherein load force transfer ends are formed at two sides of the central line of the circular ring structure; a plurality of force transfer points used for adjusting load proportions are arranged on the load force transfer ends. According to the load decomposing device, the existing straight-bar lever is replaced by the circular ring structure; by means of the lever principle, a single load is decomposed into two vertical loads, the positions are adjusted by the force transfer points, and the loading of different load proportions is realized; in addition, the circular ring structure is adopted, the lever amplification proportion is small, the problem of overlarge lever ratio is overcome, and the practicability is stronger.
Description
Technical field
The utility model belongs to load decomposition technique, is specifically related to a kind of device that utilizes lever principle to carry out load decomposition.
Background technique
In the time that the distribution of load loads, the usage of lever is more common, but general lever is straight-bar, and its usage is that a load is decomposed into two parallel load of distributing according to certain ratio row.Also there is special method as the load of two decomposition being in to several angle or vertical, but the shortcoming of this usage is to have amplified lever size, lever ratio as required in the load ratio of 1:2 may reach 1:4, and too large lever ratio is very unstable in lever application, generally need not as far as possible.
Model utility content
The utility model object: provide one can effectively load be resolved into two vertical amounts, and can not amplify the load decomposing unit of the size of lever.
The technical solution of the utility model: a kind of load decomposing unit, it comprises circle structure, the center line both sides of this circle structure are load force transfer end, are provided with some power transmission points that regulate for load proportion in load force transfer end.
Described power transmission point is interconnected to slide rail.
On slide rail, be provided with the slide block for connecting dowel bar and can moving along slide rail.
When power transmission, slide block is consistent with line direction and the power transmission direction in the circle structure center of circle, and two slide blocks are mutually vertical with the line in the circle structure center of circle.
Technique effect of the present utility model: the utility model replaces existing straight-bar lever with annulus, and uses for reference lever principle, realizes single load is resolved into two normal loads, and can put position regulation by power transmission, realizes the loading of different loads ratio.In addition, adopt circle structure, lever amplification ratio is little, has overcome the excessive problem of lever ratio, has more practicability.

Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described further:
Please refer to Fig. 1, it is the structural representation of the utility model load decomposing unit the first mode of execution.
Under load decomposing unit comprise circle structure 1, the center line both sides of this circle structure are load force transfer end, be provided with the power transmission regulating for load proportion and put a B and two C are put in power transmission in load force transfer end, load(ing) point A is in the centre symmetry line of circle structure.
During to load(ing) point A imposed load F, be decomposed into two component F1 and F2 by circle structure, when enforcement, guide the direction of two component F1 and F2 into the circle structure center of circle by pull bar or stay cord, can obtain two orthogonal load.Wherein, the angle of F1 and F is that the angle of θ 1, F2 and F is θ 2,
tan θ 1=F2/F1, θ 1+ θ 2=90 °.It is θ 1 that a B and the line of circle structure center of circle O and the angle of centre symmetry line are put in power transmission, and it is θ 2 that two C and the line of circle structure center of circle O and the angle of centre symmetry line are put in power transmission.
By regulating the position of two power transmission point B and C, the size of adjustable θ 1 and θ 2, thus the ratio of adjusting F2/F1 obtains different load ratios.This structure obtains different load ratios by adjusting angle, can realize the angle adjustment of angular range in circle structure, also there is no actual amplification lever ratio, and stability in use is better.
Please refer to Fig. 2 and Fig. 3, it is the structural representation of the utility model load decomposing unit the second mode of execution.
Under load decomposing unit comprise circle structure, there are symmetrical two slide rail one 2a and slide rail two 2b in the center line both sides of this circle structure 1, and slide block one 3a and slide block two 3b are housed respectively on two slide rails, above-mentioned slide block can slide on slide rail.Slide into after specified position, slide block can be fixed on slide rail by fixed block.Two Force transmission parts one 4a and Force transmission parts two 4b are articulated and connected with slide block one 3a and slide block two 3b respectively.Force transmission parts one 4a and Force transmission parts two 4b point to respectively the circle structure center of circle.
During to load(ing) point 5 imposed load F, be decomposed into two component F1 and F2 by circle structure, F1 is along Force transmission parts two 4b, and F2, along Force transmission parts one 4a, obtains two orthogonal load.Its load decomposition principle is identical with principle described in the first mode of execution.
Regulate the position of two power transmission points by sliding slider one 3a and slide block two 3b, the angle of the center line of adjustable two Force transmission partses and circle structure, thus the ratio of adjusting F1 and F2 obtains different load ratios.This structure can be adjusted at any time slide position and obtain different load ratios, and without change circle structure, has larger convenience and versatility.
