[0015] Preferably, the manual unit includes a rotating rod, the outer end of the rotating rod is fixedly installed with a circular torsion handle, the rotating rod is rotatably installed at the center position of the fixed box through a bearing, the inner end of the rotating rod is an elliptical plate, and the two ends of the elliptical plate are rotatably installed with two force transmission rods through an axle pin, and the outer ends of the two force transmission rods are rotatably installed with axle pin blocks through an axle pin, and the two axle pin blocks are fixedly installed to the top ends of the two push rods, and two semicircular stabilizing grooves are provided on the outer side of the fixed box, and the angle between the two semicircular stabilizing grooves with the rotating rod as the axis is 45 degrees, and an elastic groove is provided on the inner side of the circular torsion handle, and a stabilizing rod is slidably installed in the elastic groove A spring is installed between the stabilizing rod and the elastic groove, and the stabilizing rod cooperates with the semicircular stabilizing groove to improve the static stability of the circular torsion handle; the circular torsion handle is rotated to cooperate with the block, the circular torsion handle drives the rotating rod to rotate, and the rotating rod drives the elliptical plate to rotate.

The two locking blocks cooperate with the corresponding two locking grooves to fix the electrical appliance fixing skeleton mechanism on the fixing box.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention installs the electrical appliance fixing frame mechanism on the frame fixing mechanism, inserts the plug-in block into the corresponding socket, and the matching block enters the corresponding matching notch. Then, the circular twisting handle rotates the matching block, and the circular twisting handle drives the rotating rod to rotate, and the rotating rod drives the elliptical plate to rotate.

The magnetic properties of the two ends of the high-strength permanent magnet are opposite to the magnetic properties of the corresponding two magnet rods, attracting the two magnet rods to approach each other, and the two magnet rods drive the two extrusion plates to approach each other. The two extrusion plates drive the corresponding four locking blocks to be inserted into the four locking grooves, so that the plug-in blocks can be locked in the fixed box. When the circular torsion handle is rotated, the stabilizing rod enters the other semicircular stabilizing groove from one semicircular stabilizing groove. The elastic force of the spring improves the stability of the circular torsion handle when it is stationary, and the fixed skeleton mechanism of the electrical appliance can be quickly fixed.

[0021] The present invention rotates the torsion handle 45° in the opposite direction, and through the transmission of the above-mentioned force, the two push rods approach each other, and the push rod drives the positioning rod to leave the positioning groove, thereby releasing the fixation between the fixing box and the two vertical rails. The use height of the skeleton fixing mechanism between the two vertical rails can be adjusted, and the high-strength permanent magnet is in a vertical state. The two magnet rods and the corresponding passive gears lose magnetism. Through the reset tension of the plastic tension spring, the two extrusion plates located on the outside of the same high-strength permanent magnet move away from each other, and the locking block leaves the corresponding locking groove, releasing the fixation of the plug-in block. At the same time, the electrical appliance fixing skeleton mechanism is pulled upward, and the two plug-in blocks leave the corresponding two sockets, so that the skeleton fixing mechanism and the electrical appliance fixing skeleton mechanism can be quickly disassembled.

[0022] In the present invention, since the tops of the two slide rail grooves opened on the tops of the two vertical rails are open, the two slide rail blocks outside the fixing box slide out from the tops of the two slide rail grooves, and the skeleton fixing mechanism can be removed from between the two vertical rails. Similarly, the number of skeleton fixing mechanisms in use can be increased.

[0023] In summary, the present invention achieves a breakthrough improvement in the installation and maintenance efficiency of power cabinets through the magnetic coupling locking mechanism, and can quickly disassemble and assemble the electrical fixed skeleton mechanism. It is particularly suitable for smart substation scenarios where components need to be frequently replaced. The open top design of the vertical rail allows the slide rail block to be vertically inserted / withdrawn, realizing the overall rapid disassembly and assembly of the skeleton mechanism. The installation quantity can be selected to increase the installation height. BRIEF DESCRIPTION OF THE DRAWINGS

Example 1

[0047] like Figures 1-14 As shown, the present invention provides a power cabinet component fixing frame that can be quickly disassembled and assembled, including a power cabinet 1, two vertical rails 2, three frame fixing mechanisms 3 and three electrical appliance fixing frame mechanisms 4. The outer side of the power cabinet 1 is rotatably installed with a cabinet door 12, and two magnet bars 14 are provided on the inner side of the cabinet door 12. The two magnet bars 14 are attracted to the sides of the power cabinet 1. A plurality of heat dissipation holes 11 are provided on both sides of the power cabinet 1, and a transparent plate 13 is provided on the cabinet door 12. The two vertical rails 2 are fixedly installed on the inner walls of both sides of the power cabinet 1, and the inner sides of the two vertical rails 2 are provided with slide rail grooves 21.

The three frame fixing mechanisms 3 are slidably installed between the two vertical rails 2, and the three electrical appliance fixing frame mechanisms 4 are installed on the three frame fixing mechanisms 3.

[0048] Specifically, the three sets of skeleton mechanisms have an independent load-bearing capacity of 80kg / set, and the slide rail system supports a vertical movement speed of 0.5m per second (compared to 0.2m / s for traditional guide rail systems).

[0049] like Figure 5 、 Figure 7-12 As shown, in this embodiment, the skeleton fixing mechanism 3 includes a fixing box 31, a manual unit 35, and two permanent magnet units 39. A blocking plate 32 is fixedly installed on the rear side of the fixing box 31, and two transverse slide bars 33 are fixedly installed in the fixing box 31. Four extrusion plates 34 are slidably installed on the outer sides of the two transverse slide bars 33. Plastic tension springs 341 are fixedly installed on the outer sides of the four extrusion plates 34. Force blocks 342 are fixedly installed on the outer sides of the four plastic tension springs 341. The four force blocks 342 are fixedly installed on the bottom inner wall of the fixing box 31; the tension of the plastic tension spring 341 provides a reset tension for the extrusion plate 34.

[0050] like Figure 5 、 Figure 7-12 As shown, in this embodiment, slide rail blocks 36 are fixedly installed on both sides of the fixed box 31, and circular holes 361 are opened on the two slide rail blocks 36. Positioning rods 313 are slidably installed in the two circular holes 361. The circular holes 361 are slidably connected to the inner walls of the corresponding slide rail grooves 21, and the positioning rods 313 are adapted to the corresponding positioning grooves 22. Push rods 310 are fixedly installed on the inner sides of the two circular holes 361, and push rod sliding holes 345 are opened on the four extrusion plates 34. The two push rods 310 are slidably connected to the inner walls of the corresponding two push rod sliding holes 345; the two positioning rods 313 enter the two positioning grooves 22 to fix the fixed box 31 between the two vertical rails 2.

[0051] like Figure 5 、 Figure 7-12 As shown, in this embodiment, the permanent magnet unit 39 includes a passive rod 391, which is rotatably mounted on the rear inner wall of the fixed box 31 through a bearing, a high-strength permanent magnet 393 is fixedly mounted on the outer end of the passive rod 391, and a passive gear 392 is fixedly mounted on the outer side of the passive rod 391. A bottom groove 311 is provided at the bottom of the push rod 310, and a rack 312 is fixedly mounted on the top inner wall of the bottom groove 311, and the rack 312 is meshed with the passive gear 392. The high-strength permanent magnet 393 is located between the corresponding two extrusion plates 34, and a magnet rod 343 is fixedly mounted on the inner side of the two extrusion plates 34. The inner sides of the two magnet rods 343 have opposite magnetism, and the two ends of the high-strength permanent magnet 393 have opposite magnetism. The two ends of the high-strength permanent magnet 393 are adapted to the two magnet rods 343.

[0052] Specifically, the high-strength permanent magnet 393 is in a horizontal state, and the magnetic properties of both ends of the high-strength permanent magnet 393 are the same as those of the corresponding two magnet rods 343, attracting the two magnet rods 343 to approach each other, and the two magnet rods 343 drive the two extrusion plates 34 to approach each other, and the two extrusion plates 34 drive the corresponding four locking blocks 344 to insert into the four locking slots 44, so that the plug-in block 43 can be locked in the fixed box 31. The magnetic attraction between the high-strength permanent magnet 393 and the two magnet rods 343 is greater than the pulling force of the plastic tension spring 341. The polarity matching design of the high-strength permanent magnet (surface magnetic energy product ≥50MGOe) and the magnet rod is adopted to achieve a contact pressure of >300N. Compared with the traditional screw fixing method, the installation time is shortened from an average of 5 minutes / piece to 8 seconds / piece, and it can withstand a static load of 50kg in the locked state (GB / T 2423.5-2019 standard test).

[0053] like Figure 13 、 Figure 14 As shown, in this embodiment, the manual unit 35 includes a rotating rod 352, the outer end of the rotating rod 352 is fixedly mounted with a round twist handle 351, the rotating rod 352 is rotatably mounted at the center of the fixed box 31 through a bearing, the inner end of the rotating rod 352 is an elliptical plate 353, and the two ends of the elliptical plate 353 are rotatably mounted with two force transmission rods 354 through a shaft pin, and the outer ends of the two force transmission rods 354 are rotatably mounted with a shaft pin block 355 through a shaft pin, and the two shaft pin blocks 355 are connected to the two push rods 310 The top of the fixing box 31 is fixedly installed, and two semicircular stable grooves 301 are provided on the outside of the fixing box 31. The angle between the two semicircular stable grooves 301 is 45° with the rotating rod 352 as the axis. An elastic groove 357 is provided on the inside of the circular torsion handle 351. A stabilizing rod 356 is slidably installed in the elastic groove 357. A spring 358 is installed between the stabilizing rod 356 and the elastic groove 357. The stabilizing rod 356 cooperates with the semicircular stable groove 301 to improve the static stability of the circular torsion handle 351.

[0054] Specifically, the circular torsion handle 351 is rotated 45 degrees to match the block, and the circular torsion handle 351 drives the rotating rod 352 to rotate, and the rotating rod 352 drives the elliptical plate 353 to rotate, and the elliptical plate 353 pushes the two push rods 310 away from each other through the two force transmission rods 354 and the two shaft pin blocks 355, and drives the passive gear 392 to rotate 90 degrees through the rack 312, and the passive gear 392 drives the high-strength permanent magnet 393 to rotate 90 degrees through the passive rod 391, so that the high-strength permanent magnet 393 is in a horizontal state, and the circular torsion handle 351 is rotated 45 degrees in the opposite direction, and the high-strength permanent magnet 393 is in a vertical state, and the two magnet rods 343 and the corresponding passive gear 392 lose their magnetism, and the elliptical plate + force transmission rod mechanism realizes the conversion of 270° rotational motion into linear motion (motion conversion efficiency 92%), and the push rod stroke is optimized, and the locking can be completed with an effective stroke of 12mm (traditional slide rails require ≥25mm).

[0055] like Figure 7 、 Figure 9 As shown, in this embodiment, the electrical appliance fixing skeleton mechanism 4 includes two support plates 41, and two L-shaped mounting strips 42 are fixedly installed on the outer sides of the two support plates 41, and matching blocks 45 are fixedly installed on the inner sides of the two support plates 41. The two matching blocks 45 match with the two matching notches 38, and the inner sides of the two matching blocks 45 are fixedly installed with plug-in blocks 43, and the two plug-in blocks 43 match with the two sockets 37. The electrical appliance fixing skeleton mechanism 4 is installed on the outer side of the fixing box 31. Two sockets 37 are provided on the top of the fixing box 31, and matching notches 38 are provided on the outer sides of the two sockets 37; the plug-in blocks 43 are inserted into the corresponding sockets 37, and the matching blocks 45 enter the corresponding matching notches 38 to perform preliminary positioning of the electrical appliance fixing skeleton mechanism 4.

[0056] like Figure 7 、 Figure 9 As shown, in this embodiment, two locking grooves 44 are provided on both sides of the plug-in block 43, and two locking blocks 344 are fixedly installed on the inner side of the extrusion plate 34. The two locking blocks 344 cooperate with the corresponding two locking grooves 44 to fix the electrical appliance fixing skeleton mechanism 4 on the fixing box 31.

[0057] Working method: When in use, the electrical appliance fixing frame mechanism 4 is installed on the frame fixing mechanism 3, the plug-in block 43 is inserted into the corresponding socket 37, the matching block 45 is inserted into the corresponding matching notch 38, and then the round twisting handle 351 is rotated 45 degrees about the matching block. The round twisting handle 351 drives the rotating rod 352 to rotate, and the rotating rod 352 drives the elliptical plate 353 to rotate. The elliptical plate 353 pushes the two push rods 310 away from each other through the two force transmission rods 354 and the two shaft pin blocks 355. The two push rods 310 push the two positioning rods 313 into the two positioning grooves 22, thereby fixing the fixing box 31 between the two vertical rails 2;

[0058] When the push rod 310 moves, the rack 312 drives the driven gear 392 to rotate 90 degrees. The driven gear 392 drives the high-strength permanent magnet 393 to rotate 90 degrees through the driven rod 391, so that the high-strength permanent magnet 393 is in a horizontal state. The magnetic properties of the two ends of the high-strength permanent magnet 393 are opposite to those of the corresponding two magnet rods 343, which attract the two magnet rods 343 to approach each other. The two magnet rods 343 drive the two extrusion plates 34 to approach each other. The two extrusion plates 34 drive the corresponding four locking blocks 344 to insert into the four locking grooves 44, so that the plug-in block 43 can be locked in the fixed box 31.

[0059] When the torsion handle 351 is rotated, the stabilizing rod 356 enters the other semicircular stabilizing groove 301 from one semicircular stabilizing groove 301. The elastic force of the spring 358 improves the stability of the torsion handle 351 when it is stationary, and the electrical appliance fixing frame mechanism 4 can be quickly fixed.

[0060] When disassembling, the round twisting handle 351 is rotated 45° in the opposite direction. Through the transmission of the above-mentioned force, the two push rods 310 are brought closer to each other, and the push rod 310 drives the positioning rod 313 to leave the positioning groove 22, releasing the fixation between the fixing box 31 and the two vertical rails 2, and the use height of the skeleton fixing mechanism 3 between the two vertical rails 2 can be adjusted. The high-strength permanent magnet 393 is in a vertical state, and the two magnet rods 343 and the corresponding high-strength permanent magnet 393 lose attraction. Through the reset tension of the plastic tension spring 341, the two extrusion plates 34 located on the outside of the same high-strength permanent magnet 393 move away from each other, and the locking block 344 leaves the corresponding locking groove 44, releasing the fixation of the plug-in block 43, and at the same time pulling the electrical appliance fixing skeleton mechanism 4 upward, the two plug-in blocks 43 leave the corresponding two sockets 37, and the skeleton fixing mechanism 3 and the electrical appliance fixing skeleton mechanism 4 can be quickly disassembled;

[0061] Since the tops of the two slide rail grooves 21 opened on the tops of the two vertical rails 2 are open, the two slide rail blocks 36 outside the fixing box 31 slide out from the tops of the two slide rail grooves 21, and the skeleton fixing mechanism 3 can be removed from between the two vertical rails 2. Similarly, the number of skeleton fixing mechanisms 3 used can be increased.

[0062] Specifically, the magnetic retention rate is >98% under high temperature (85°C) environment (1000-hour aging test), and the displacement under vibration test (10-2000Hz, 3Grms) is <0.15mm (IEC 60068-2-6 standard). Example 2

[0063] like Figure 2-Figure 11 As shown, this embodiment is further optimized based on the embodiment 1, and the same parts as the above technical solutions will not be repeated here. Figure 2 、 Figure 11 As shown, in order to better implement the present invention, the following setting is particularly adopted: in this embodiment, the plug block 43 and the socket 37 are tapered (taper 1:50), and the insertion guide angle is 15°, achieving a blind plugging success rate of >99%.

[0064] In this embodiment, the four locking blocks 344 are symmetrically distributed (with a spacing tolerance of ±0.05 mm) to ensure multi-point load distribution.

[0065] In this embodiment, the plastic tension spring 341 is made of PPS+30% GF (tensile strength ≥ 180 MPa), and the creep amount is less than 0.1% under the working condition of -40°C to 120°C.

[0066] In this embodiment, the surface of the magnet rod is plated with a nickel-copper composite layer (thickness 50 μm), and the hysteresis loss is reduced to <3%.

[0067] In this embodiment, the distance between the skeleton structure and the cabinet wall is ≥8 mm, forming a vertical air duct (the air exchange volume is increased by 30% when the wind speed is 0.8 m / s).

[0068] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
