Description

Technical Field

[0001] This utility model relates to the field of electrical equipment installation technology, and in particular to an electrical equipment installation frame that is resistant to electromagnetic interference. Background Technology

[0002] Electrical equipment mounting racks refer to the structural frames used to fix and support electrical equipment. Racks are often referred to as rack servers and are mainly used to fix plug-in boards, housings and equipment in telecommunications cabinets. Especially in the application of motor assembly machines, they can significantly improve the working efficiency of the equipment. In addition, racks are also widely used in network cabling rooms, floor wiring closets, central computer rooms, data centers, control centers and monitoring centers.

[0003] With the widespread use of electronic devices, electromagnetic interference has become increasingly prominent, especially in environments where electronic devices are installed in high density. Electromagnetic interference can lead to a decline in equipment performance or even failure. Currently, most electrical equipment mounting racks on the market are made of metal materials, which have a certain shielding effect, but are still insufficient in the face of high-frequency electromagnetic waves. Moreover, most electrical equipment is currently fixed by multiple sets of bolts. When repairing electrical equipment, it is necessary to disassemble multiple sets of bolts, which brings great inconvenience to the operation and has poor applicability. Utility Model Content

[0004] In view of the above-mentioned problems existing in the prior art, the main purpose of this utility model is to provide an electrical equipment mounting frame that is protected against electromagnetic interference.

[0009] In a preferred embodiment, the crossbeam is provided with a clamping assembly, which includes a groove formed inside the crossbeam, a bidirectional lead screw rotatably connected inside the groove, and a fixing rod fixedly connected inside the groove and on one side of the bidirectional lead screw.

[0011] In a preferred embodiment, the clamping assembly further includes clamping blocks threaded to both ends of the bidirectional lead screw, each clamping block being slidably connected to a fixed rod, and each clamping block having a mounting bracket fixedly connected to its top.

[0012] By adopting the above technical solution, the setting of the fixing rod can play an important role in limiting the movement of the clamping block, thereby ensuring the normal use of the clamping block.

[0015] In a preferred embodiment, the clamping member and the fixing block are both fixedly connected to one side of the fixing block, one end of the torsion spring overlaps the outside of one of the fixing blocks, and the other end of the torsion spring overlaps the outside of the other fixing block.

[0016] By adopting the above technical solution, the normal use of the torsion spring can be ensured.

[0017] In a preferred embodiment, a rubber block is fixedly connected to one end of each clamping member, a drive motor is fixedly installed on the outer side of the crossbeam, and the output shaft of the drive motor extends into the interior of the slide groove and is fixedly connected to a bidirectional lead screw.

[0018] By adopting the above technical solution, the rotation of the output shaft of the drive motor can drive the bidirectional lead screw to rotate.

[0019] In a preferred embodiment, the column is fixedly connected to all four sides by fixing plates, and each fixing plate is provided with locking bolts. The fixing plates are connected to the base by locking bolts, and four reinforcing ribs are fixedly connected between the column and the base.

[0020] By adopting the above technical solution and adding reinforcing ribs, the connection strength between the column and the base can be improved.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] 1. In this utility model, by using multi-layer metal mesh and conductive foam as shielding components, and combining them with grounding components, high-frequency electromagnetic waves can be effectively prevented from interfering with electrical equipment. The multi-layer metal mesh can reflect and absorb electromagnetic waves through its conductivity, while the conductive foam further absorbs electromagnetic waves that the multi-layer metal mesh cannot completely shield, thereby reducing electromagnetic wave interference to internal equipment. The grounding component, by connecting the shielding components to the earth, guides the absorbed electromagnetic waves to the earth, further enhancing the shielding effect. In addition, the addition of multi-layer metal mesh, through its multi-layer structure, further enhances the shielding effect against high-frequency electromagnetic waves.

[0023] 2. In this utility model, the rotation of the bidirectional lead screw can drive the two clamping blocks to move in opposite directions, thereby achieving the purpose of clamping electrical equipment with the help of the two clamping blocks. The position of the clamping blocks can be adjusted to be used for electrical equipment of different sizes, thereby improving the applicability of the equipment. Attached Figure Description

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] Reference Figure 1-4 An electromagnetic interference-resistant electrical equipment mounting rack includes a rack body 1, which comprises a base 101, a column 102, and a crossbeam 103. The column 102 is mounted on the top of the base 101, and the crossbeam 103 is fixedly connected to the top of the column 102. Shielding components 2 are provided on the outer sides of the rack body 1. The shielding components 2 include multi-layer metal mesh 201 and conductive foam 202. The outer side of the rack body 1 is covered by the multi-layer metal mesh 201, and conductive foam 202 is filled between the rack body 1 and the multi-layer metal mesh 201. A grounding component is provided on the outer side of the rack body 1. This solution utilizes multi-layer metal mesh 201... 01 and conductive foam 202 serve as shielding component 2, and together with the grounding component, they can effectively prevent high-frequency electromagnetic waves from interfering with electrical equipment. The multi-layer metal mesh 201 reflects and absorbs electromagnetic waves through its conductivity, while the conductive foam 202 further absorbs electromagnetic waves that the multi-layer metal mesh 201 fails to completely shield, thereby reducing electromagnetic interference to internal equipment. The grounding component connects the shielding component 2 to the earth, guiding the absorbed electromagnetic waves to the earth, further enhancing the shielding effect. In addition, the addition of the multi-layer metal mesh 201 further enhances the shielding effect against high-frequency electromagnetic waves through its multi-layer structure.

[0031] Specifically, the grounding assembly includes a grounding wire 3 disposed on the outside of the frame body 1. A grounding terminal 4 is fixedly connected to one end of the grounding wire 3 away from the frame body 1, and the other end of the grounding wire 3 away from the grounding terminal 4 is fixedly connected to the shielding assembly 2. A clamping assembly is disposed inside the crossbeam 103. The clamping assembly includes a slide groove 17 formed inside the crossbeam 103. A bidirectional lead screw 12 is rotatably connected inside the slide groove 17. Rotation of the bidirectional lead screw 12 can drive two clamping blocks 5 to move in opposite directions, thereby enabling the clamping of electrical equipment using the two clamping blocks 5. The clamping block 5 is adjustable to accommodate electrical equipment of different sizes, thereby improving the applicability of the equipment. A fixing rod 11 is fixedly connected inside the slide groove 17 and on one side of the bidirectional lead screw 12. The clamping assembly also includes clamping blocks 5 threaded to both ends of the bidirectional lead screw 12. The clamping blocks 5 are slidably connected to the fixing rod 11. The fixing rod 11 plays an important role in limiting the movement of the clamping blocks 5 to ensure the normal use of the clamping blocks 5. A mounting bracket 6 is fixedly connected to the top of each clamping block 5.

[0032] Specifically, each mounting bracket 6 has a fastening assembly at its top. This fastening assembly includes a clamping member 7 rotatably mounted inside the mounting bracket 6. Through the reaction force of a torsion spring 9, the clamping member 7 can press against the electrical equipment, thereby increasing the fastening force between the rubber block 8 and the electrical equipment. This further improves the stability of the electrical equipment during installation. A torsion spring 9 is fitted onto the rotating shaft of each clamping member 7. A fixing block 10 is fixedly connected to one side of each clamping member 7 and a fixing block 10. One end of the torsion spring 9 overlaps the outside of one fixing block 10, and the other end overlaps the outside of the other fixing block 10, ensuring the normal operation of the torsion spring 9. A rubber block 8 is fixedly connected to one end of each clamping member 7. The outer side of the crossbeam 103 is fixed... A drive motor 13 is installed, and the rotation of the output shaft of the drive motor 13 can drive the bidirectional lead screw 12 to rotate. The output shaft of the drive motor 13 extends into the interior of the slide groove 17 and is fixedly connected to the bidirectional lead screw 12. Fixing plates 16 are fixedly connected around the column 102. Locking bolts 15 are provided inside the fixing plates 16. The fixing plates 16 and the base 101 are connected by locking bolts 15. The cooperation of the fixing plates 16 and locking bolts 15 allows the operator to connect the base 101 and the column 102. Four reinforcing ribs 14 are fixedly connected between the column 102 and the base 101. The setting of the reinforcing ribs 14 can improve the connection strength between the column 102 and the base 101.

[0033] Working Principle: When installing electrical equipment, the operator can place the equipment between two clamping blocks 5 and start the drive motor 13 via an external controller. The rotation of the output shaft of the drive motor 13 drives the bidirectional lead screw 12 to rotate, thereby causing the two clamping blocks 5 to move in opposite directions. This allows the two clamping blocks 5 to clamp the electrical equipment. The reaction force of the torsion spring 9 pushes the clamping parts 7 to press against the electrical equipment, thereby increasing the tightness between the rubber block 8 and the electrical equipment and further improving the stability of the electrical equipment during installation. By using a multi-layer metal mesh 201 and conductive foam 202 as shielding components 2, combined with a grounding component, high-frequency electromagnetic waves can be effectively prevented from interfering with the electrical equipment. The multi-layer metal mesh 201 reflects and absorbs electromagnetic waves through its conductivity, while the conductive foam 202 further absorbs electromagnetic waves that the multi-layer metal mesh 201 cannot completely shield, thereby reducing electromagnetic interference to the internal equipment. The grounding component connects the shielding component 2 to the earth, guiding the absorbed electromagnetic waves to the earth, further enhancing the shielding effect.
