Specific embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates basic structure of the invention, therefore it only shows the composition relevant to the invention.
As shown in Figure 1, a kind of bus duct is fixedly mounted structure, including bus duct ontology 1, the first fixed installation portion 2 and the
Two fixed installation portions 3, wherein the first fixed installation portion 2 is symmetrically disposed on outside the preceding frid 11 and drop end 12 of bus duct ontology 1
Side, the first fixed installation portion 2 include preceding angle steel 21 and rear angle steel 22, and preceding angle steel 21 passes through the preceding card positioned at its left and right ends respectively
Fastener 211 is snapped connection with preceding frid 11, is passed through after fastener 211 and preceding angle steel 21 before fixing piece 212 sequentially passes through before first
Nut is fixed；Angle steel 22 is snapped connection by being located at the rear fastener 221 of its left and right ends with drop end 12 respectively afterwards, the
Fixing piece 222 is fixed after sequentially passing through rear fastener 221 and rear angle steel 22 by nut after one；Second fixed installation portion 3
Including being symmetrically arranged in the preceding channel steel 31 and rear channel steel 32 in 12 outside of preceding frid 11 and drop end, preceding channel steel 31 and rear channel steel
Fixing piece 342 and left channel steel 34, right channel steel 33 after fixing piece 341 and second before 32 left part, right part pass through second respectively
It is fixedly connected, it is middle spring to pass through several between preceding angle steel 21 and preceding channel steel 31, between rear angle steel 22 and rear channel steel 32 respectively
Fixing piece 4 connects, and the coefficient of elasticity that the preceding flexible fastening piece 41 in each of preceding 11 outside of frid is located in middle spring fixing piece 4 is big
It is located at the coefficient of elasticity of the rear flexible fastening piece 42 in each of 12 outside of drop end in middle spring fixing piece 4；Because of the bus
Structure is fixedly mounted by the rear upper installing hole 351 on mounting plate 35 and when lower mounting hole 352 is installed afterwards in slot, when suffering from the external world
When shaking or shaking, the mounting fixing parts in rear upper installing hole 351 and rear lower mounting hole 352 can be used as fulcrum, and it is micro- to there is generation
The trend of thin tail sheep, and since the torque of each preceding flexible fastening piece 41 is longer, the torque of each rear flexible fastening piece 42 is shorter,
Therefore each preceding flexible fastening piece 41 is more easily also more likely to generate compared with long displacement, and each rear flexible fastening piece 42 is easier
Also it is more likely to generate compared with short essay, therefore is arranged in middle spring fixing piece 4 and is located at the preceding elasticity in each of preceding 11 outside of frid
The coefficient of elasticity of fixing piece 41, which is greater than, is located at the rear flexible fastening piece 42 in each of 12 outside of drop end in middle spring fixing piece 4

Property coefficient is greater than the coefficient of elasticity of centrally located flexible fastening piece, this is because preceding channel steel 31 and rear channel steel 32 lead to respectively
Cross before the second of its both ends that fixing piece 342 is fixed on left channel steel 34 and right channel steel 33 after fixing piece 341 and second, when suffering from
The external world shakes or when vibration, is both greater than located at positioned at the trend that is subjected to displacement of flexible fastening piece and displacement of left and right ends
Between position flexible fastening piece trend and displacement, therefore specific setting is located at the elasticity system of the flexible fastening piece of left and right ends
Number is greater than the coefficient of elasticity of centrally located flexible fastening piece, is more advantageous to the fixed installation structure and integrally plays buffering shake
Dynamic effect, so that the Global Macros fixed installation structure, prolongs its service life.
Specifically, preceding fastener 211 and 221 section of rear fastener are in groove profile, and notch direction is respectively directed to preceding angle steel 21
With rear angle steel 22, card slot is respectively arranged with close to the side of bus duct ontology 1 in preceding fastener 211 and rear fastener 221 and is used for
The edge flanging of frid 11 and drop end 12 before accommodating.
Specifically, left and right ends offer preceding upper fixation hole respectively on the lower trough rim of preceding channel steel 31, under rear channel steel 32 on trough rim
Left and right ends upper fixation hole after offering respectively, and size of the preceding upper fixation hole under preceding channel steel 31 on trough rim left and right directions is greater than
The size of fixing piece 341 before second, upper size of the fixation hole under rear channel steel 32 on trough rim left and right directions is solid after being greater than second afterwards
Determine the size of part 342, in order to according to the fixation of different model and the bus duct ontology of size and installation needs, to adjust left slot
The position of steel 34 and right channel steel 33 on the lower trough rim of preceding channel steel 31 and right channel steel 32 on left and right directions.
Specifically, the position of corresponding preceding upper fixation hole offers front lower fixation on the upper trough rim of left channel steel 34, right channel steel 33
Hole, the position of upper fixation hole offers rear lower fixed hole, and preceding lower fixed hole trough rim front-rear direction on left channel steel 34 after corresponding
On size be greater than second before fixing piece 341 size, size of the rear lower fixed hole on left channel steel 34 on trough rim front-rear direction
The size of fixing piece 342 after greater than second, in order to according to the fixation of different model and the bus duct ontology of size and installation need
It wants, to adjust the position of preceding channel steel 31 and rear channel steel 32 on the upper trough rim of left channel steel 34 and right channel steel 33 on front-rear direction.
Specifically, position closer to the front relative to preceding lower fixed hole on the lower trough rim of left channel steel 34, right channel steel 33 is also opened
It is after the installation is completed with the mounting fixing parts in rear upper installing hole 351 and rear lower mounting hole 352, preceding equipped with front lower mounting hole 343
Lower mounting hole 343 is to meet the location and installation needs in another face.
Specifically, left channel steel 34, right channel steel 33 rear end be additionally provided with mounting plate 35, upper peace after being offered on mounting plate 35
It fills hole 351 and lower mounting hole 352, rear upper installing hole 351 is located above the upper trough rim of left channel steel 34, right channel steel 33 afterwards, rear lower peace
Dress hole 352 is located between the upper trough rim and lower trough rim of left channel steel 34, right channel steel 33, sets preferably, mounting plate 35 divides for left and right
2 pieces set, and the mounting plate 35 on the left side is molded as one with left channel steel 34, the mounting plate 35 on the right and right channel steel 33 are shaped to one
