Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

As shown in Figure 2, two rows of circular holes 4 with equal aperture and equal hole spacing are opened on the basic installation beam 3. is E, and E can be any value.

As shown in Figures 3 and 4, the beam body of the component mounting beam I1 is provided with mounting holes I5 which are located in the center and evenly distributed in a single row. The oblong fixing holes I6 of the same size, wherein the distance between the left and right and the upper and lower fixing holes I6 in each surface is E, and the size of the fixing holes I6 is φd×(d+1/5E).

As shown in Figure 5 and Figure 6, there are two rows of mounting holes II7 corresponding to the position and evenly distributed on the beam body of the component mounting beam II2, and the spacing between the rows is 4/5E. There are 4 oblong fixing holes II8 with corresponding positions and the same size, and the distance between the left and right and the upper and lower fixing holes II8 in each surface is E, and the size of the fixing hole II8 is the same as that of the fixing hole I6. It is an oblong hole: φd×(d+1/5E), 1/5E is the adjustable range of the installation beam, which is consistent with the step distance of the component installation beam II2 double-row hole spacing 4/5E (E-1/5E); component installation The beam widths of the beam I1 and the component mounting beam II2 are the same, and the width ranges from 2E to 3E.

As shown in Figure 1, a component mounting beam I1 and a component mounting beam II2 are used as a combination one, and the other two component mounting beams II2 are used as a combination two, and they are simultaneously vertically fixed between two basic mounting beams 3, each of which is fixed The hole I6 and the fixing hole II8 cover the respective corresponding round holes 4, that is, the round holes 4 are stacked in the respective corresponding fixing holes, and they are fixed together by passing through bolts, each fixing hole I6 and the fixing hole II8 The center line of the center line can be shifted left and right by 1/10E based on the center of the corresponding round hole 4. The beam distance ranges in combination 1 and combination 2 are both (nE-1/5E)～(nE+1/5E). When the beam width of the component installation beam I1 and the component installation beam II2 is 2E, n is a natural number greater than or equal to 2, and when their beam width is greater than 2E, n is a natural number greater than or equal to 3.

For component mounting beam combination 1, the reference dimension of the component mounting hole distance (referring to the component mounting hole distance when the centerline of the component mounting beam fixing hole coincides with the basic mounting beam hole center) is nE-2/5E and nE+2/5E, The distance between the mounting hole I5 of the component mounting beam I1 and the left and right mounting holes II7 of the component mounting beam II2 is nE-2/5E and nE+2/5E, and the fixing hole of the mounting beam is adjusted relative to the round hole by moving left and right The position of the installation hole can be obtained from two data segments ranging from (nE-3/5E) to (nE-1/5E) and (nE+1/5E) to (nE+3/5E).

For the component mounting beam combination 2, the reference dimension of the component mounting hole distance is nE and the expanded nE-4/5E and nE+4/5E, by adjusting the mounting beam fixing long hole to achieve (nE-1/5E)～(nE+ 1/5E) to supplement the middle data segment, and expand (nE-E)～(nE-3/5E) and (nE+3/5E)～(nE+E) two data segments.

Combining the above two combinations, the data segment of the component mounting hole distance ranging from (n-1)E to (n+1)E twice the equal hole spacing can be obtained. If combination 2 is replaced by a combination of two component mounting beams I1, It can also realize the data segment of (nE-3/5E)～(nE+3/5E); when n is n-1, n+1..., all the size data of the component mounting hole distance can be continuous, reaching the The effect of installing components of any size.

In the utility model, one of the 4 fixing holes I6 on the same surface of the component mounting beam I1 and one of the 4 fixing holes II8 on the same surface of the component mounting beam II2 can be replaced by a round hole with a diameter of φd. The hole distance between the hole and the adjacent fixing hole II8 or fixing hole I6 is E, and when the component installation hole distance is the reference size of 1/5E step, they are all directly fastened to the round hole (especially as a busbar support beam), so as to Improve the positioning accuracy of the installation beam and the consistency and efficiency of installation. When the installation beam is not at the reference position, the three screws with two oblong holes fastened on both sides can also meet the design fastening strength.

Let’s take the installation of MNS cabinet as an example. The equal hole distance on the column profile is E=25 (abbreviated as modulus in this product). The component fastening is realized by means of the mounting hole of the component mounting beam. According to conventional design deduction: if there are two identical component mounting beams, the component mounting hole distance can only be an integer multiple of its modulus 25, that is: 50, 75, 100... cannot adapt to the current diversified types of components Installation size requirements.

As shown in Figure 7 and Figure 8, this figure randomly selects n=4 times E as the center distance nE=25X4=100 of the installation beam, and substitutes the above values into the component installation beam combination 1 (nE-3/5E)～ (nE-1/5E), (nE+1/5E)～(nE+3/5E) two data segments and the middle of (nE-1/5E)～(nE+1/5E) of component installation beam combination 2 Data segment and (nE-E) ~ (nE-3/5E), (nE+3/5E) ~ (nE+E) a total of 5 data segments, respectively get 85 ~ 95, 105 ~ 115, 95 ~ 105, 75~85, 115~125, the two combinations finally get the data segment of the component mounting hole pitch from 75 to 125, which is exactly twice the modulus;

When selecting n=5, 6 times E as the installation distance of the installation beam and substituting nE and the component installation hole distance (n-1)E～(n+1)E, it can be obtained: the installation distance of the two component installation beams nE= 125 and 150, the component mounting hole pitch is from 100 to 150 and 125 to 175 data segments, and so on. According to this design scheme, the design effect that the component mounting size data is continuous and repeatable is obviously achieved. If you substitute the reference dimension 1/5E of the component mounting hole distance into it, you can get, ... 75, 80, 85, 90, 95, 100, 105, 110, 115, 120, 125... etc., with 5 steps as the reference Dimensions, when the component installation hole distance is above the reference size, the round hole is directly fastened (especially as a busbar support beam), which improves the positioning accuracy of the installation beam and the consistency and efficiency of installation.

In addition, the equal hole distance E can also be changed to 20 or any other data that meets the designer's needs to achieve the final effect of this design scheme.
