[0002] The electrical equipment installed in the control cabinet is usually fixed on a mounting plate. This mounting plate usually has a front and a back. The front is flat and used to fix the electrical equipment. The back of the mounting plate is provided with a corresponding structure connected to the support rail, so that the electrical equipment is supported and fixed by the support rail through the mounting plate.

[0003] Existing mounting plates clamp the support rail connected to the mounting plate by means of a protrusion structure provided at a certain position on the mounting plate, for example, a protrusion provided on the back of the mounting plate, or a protrusion provided on a component on the back of the mounting plate for clamping the flange of the support rail. This protrusion structure fixes and clamps the support rail in the mounting plate by means of its deformation. However, during installation and use, the protrusion structure is easily damaged due to the huge force it bears instantly, resulting in the mounting plate being unable to fix and clamp the support rail. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] The object of the present invention is to provide a fixing installation plate for electrical equipment which has a simple and stable structure and can produce very little elastic deformation of the support rail in view of the above-mentioned deficiencies in the prior art.

[0025] The following embodiments and accompanying drawings are used to further describe the specific implementation of the present invention. Here, the following embodiments of the present invention are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0026] like Figures 1 to 5 As shown, an embodiment of the present invention provides a fixed installation plate for an electrical device, comprising: a first installation surface 1 connected to the electrical device and a second installation surface 2 connected to an X-shaped support rail 5 .

[0027] In this embodiment, the fixed mounting plate is a rectangular plate, the front side is a first mounting surface 1 connected to the electrical equipment, and the back side is a second mounting surface 2 connected to the "X"-shaped support rail 5. The first mounting surface 1 is usually a flat plane, which is convenient for placing the electrical equipment firmly on it; and screw holes are provided on the first mounting surface 1, which is convenient for connecting the electrical equipment to the fixed mounting plate with bolts. The shape and size (including thickness) of the fixed connecting plate and the connection method between the electrical equipment and the fixed mounting plate can be set as needed, and the embodiment of the present invention does not specifically limit this. The "X"-shaped support rail 5 includes a top surface, two side walls 52 connected to the top surface, and flanges 51 extending outwards and connected to the bottoms of the two side walls 52, respectively.

[0028] like Figures 1 to 3 As shown, a first clamping portion 3 is provided at one end of the second mounting surface 2, and a second clamping portion 4 is provided at a set distance from the first clamping portion 3. A raised rib 6 is provided on the second mounting surface 2 between the first clamping portion 3 and the second clamping portion 4, and a first slope portion 61 is provided at one end of the rib 6 close to the first clamping portion 3. The first clamping portion 3, the second clamping portion 4 and the first slope portion 61 fix the support rail 5 on the second mounting surface 2.

[0029] In this embodiment, a first clamping part 3 is provided on the second mounting surface 2 near one end of one short side thereof, and a second clamping part 4 is provided at one end of the other short side opposite to the clamping part 3. When the support rail 5 is mounted on the second mounting surface 2, the first clamping part 3 is used to press the flange 51 of the bottom of the support rail 5 near one side thereof onto the second mounting surface 2, and the second clamping part 4 is used to press the flange 51 of the bottom of the support rail 5 near one side thereof onto the second mounting surface 2. Two raised ribs 6 are provided on the portion of the second mounting surface 2 located between the first clamping part 3 and the second clamping part 4. The direction of the ribs 6 is perpendicular to the first clamping part 3 and the second clamping part 4, i.e., perpendicular to the two short sides of the second mounting surface 2 in this embodiment, and are respectively located at the edges of the two long sides of the second mounting surface 2. A first slope 61 is provided on the end of the rib 6 near the first clamping part 3. After the support rail 5 is installed on the second mounting surface 2, the first slope portion 61 abuts against the corner connection between the side wall 52 and the bottom flange 51 of the support rail 5. The first slope portion 61 squeezes the corner connection, thereby strengthening the fixing effect of the first clamping portion 3 on the flange 51 of the support rail 5 and preventing the support rail 5 from sliding relative to the second mounting surface 2.

[0030] The number and size (eg, length, width, and height) of the ribs 6 may be set as required, and this is not specifically limited in the embodiment of the present invention.

[0031] The slope of the first slope portion 61 can be set according to the size of the corner connection between the side wall 52 of the support rail 5 and the flange 51 at the bottom. The embodiment of the present invention does not specifically limit the slope of the first slope portion 61.

[0032] Furthermore, if Figures 1 to 3 As shown, the first clamping portion 3 includes a plurality of clamping components 31, the clamping components 31 include a clamping seat 311 connected to the second mounting surface 2 and a clamping tongue 312 arranged on the top of the clamping seat 311 and extending in a direction away from the second mounting surface 2, and the clamping tongue 312 forms a trapezoidal groove 7 with the second mounting surface 2. The plurality of clamping components 31 are arranged parallel to each other.

[0033] In this embodiment, Figure 4 and Figure 5 As shown, the first clamping portion 3 includes two parallel clamping parts 31, the cross section of the clamping tongue 312 is triangular, and the bottom surface of the triangular clamping tongue 312 forms a trapezoidal groove 7 with the second mounting surface 2. When installing the support rail 5, the wider opening end of the trapezoidal groove 7 facilitates the flange 51 of the bottom of the support rail 5 located on the side of the first clamping part 3 to enter the trapezoidal groove 7. Multiple parallel clamping parts 31 facilitate fixing the flange 51 of the support rail 5 on the second mounting surface 2 through multiple clamping points.

[0034] Furthermore, if Figures 1 to 4As shown, the second clamping portion 4 includes a base 41 disposed on the second mounting surface 2, a clamping piece 42 disposed on the base 41, and a spring 43 connected to the clamping piece 42; the clamping piece 42 can reciprocate relative to the base 41, and the clamping piece 42 compresses or stretches the spring 43 when reciprocating. The space formed between the bottom of the clamping piece 42 and the second mounting surface 2 is used to accommodate the flange 51 at the bottom of the support rail 5 located on one side of the second clamping portion 4.

[0035] In this embodiment, when the clamping piece 42 moves relative to the second mounting surface 2 under the action of an external force, the spring 43 is compressed or stretched, and when the external force stops, the clamping piece 42 returns to its original position under the action of the restoring force of the spring 43. When the support rail 5 is installed, the flange 51 located on one side of the second clamping portion 4 pushes the clamping piece 42 backward so that the flange 51 can be placed on the second mounting surface 2. Then, the clamping piece 42 is reset under the action of the restoring force of the spring 43, and the flange 51 is fixed on the second mounting surface 2. This structure in which the slidable clamping piece 42 is connected to the spring 43 facilitates fixing the flange 51 located on one side of the second clamping portion 4 of the support rail 5.

[0036] Furthermore, if Figure 3 As shown, the base 41 can be integrally formed with the second mounting surface 2 .

[0037] Furthermore, the fixed mounting plate is made of metal material, such as steel, iron or alloy. In this embodiment, the fixed mounting plate and the support rail 5 are both made of zinc-aluminum alloy, which has certain flexibility and elasticity. When the support rail 5 is installed, the support rail 5 can be installed in place through slight elastic deformation of the flanges 51 on both sides of the bottom of the support rail 5.

[0038] When using the fixed mounting plate of the electrical equipment in the embodiment of the present invention, first insert the flange 51 at the bottom of the support rail 5 located on the side of the first clamping portion 3 into the trapezoidal groove 7 formed by the clamping tongue 312 and the second mounting surface 2; then, place the flange 51 at the bottom of the support rail 5 located on the side of the second clamping portion 4 on the top surface of the clamping piece 41 and press it downward; the clamping piece 41 moves backward under the pressure drive, and the spring 43 connected to the clamping piece 41 is compressed. The flange 51 finally pushes the clamping piece 41 away and contacts the second mounting surface 2, and the clamping piece 41 slides forward under the action of the restoring force of the spring 43, pressing the flange 51 on the second mounting surface 2. At this point, the installation of the support rail 5 and the second mounting surface 2 of the fixed mounting plate is completed, and the first slope portion 61 set on the rib 6 further clamps the support rail 5 and prevents the support rail 4 from sliding relative to the fixed mounting plate.

[0039] The fixed mounting plate of the electrical equipment provided by the present invention is provided with a rib including a first slope portion on the mounting surface connected to the support rail, so that when the support rail is installed, the first slope portion squeezes the corner connection of the flange of the side wall and the bottom of the support rail, thereby achieving the effect of clamping the support rail and preventing the support rail from sliding. In addition, the slope structure is simple, stable, not easy to be damaged, and causes little elastic deformation to the support rail.
