[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figures 1 to 6This utility model provides a technical solution: a frame-type electrical control cabinet, including a cabinet shell, comprising a modular cabinet body 11 and a sealing plate 12, and an outer protective plate 13 connected to the cabinet body 11. The sealing plate 12 is snapped into the cabinet body 11, and a heat dissipation pipe 121 is provided on the sealing plate 12. Both the sealing plate 12 and the outer protective plate 13 are connected to the cabinet body 11. The sealing plate 12 and the outer protective plate 13 are detachable. The heat dissipation pipe 121 is welded to the sealing plate 12, and the heat inside the cabinet body 11 can be dissipated through the heat dissipation pipe 121. A positioning component includes a limiting block 21 connected to the outer protective plate 13 by screws, a connecting block 22 welded to the cabinet body 11, a connecting shaft 23 fixed to the connecting block 22 by screws, and a limiting frame 24 rotatably connected to the connecting shaft 23. When the outer protective plate 13 is combined with the cabinet body 11, the outer protective plate 13 fits against the cabinet body 11. When the limiting frame 24 is flipped, the limiting frame 24 snaps into the limiting block 21, so that the outer protective plate 13 fits into the cabinet body 11. The cabinet 11 is installed accurately. The locking assembly includes a combination of a limiting post 3 and a stabilizing block 5. The stabilizing block 5 is fixedly connected to the outer protective plate 13. The limiting post 3 passes through the limiting frame 24, the limiting cylinder 131, and the top of the outer protective plate 13 before being spirally inserted into the interior of the stabilizing block 5, thereby limiting the outer protective plate 13 and ensuring a stable installation between the outer protective plate 13 and the cabinet 11. The sealing assembly 4 includes a fixed cylinder 41 fixed to the inner wall of the outer protective plate 13 by bolts, a sliding cylinder 42 slidably sleeved on the outside of the fixed cylinder 41, and a sleeve 43 connected to the sliding cylinder 42 by threaded engagement. The sliding cylinder 42 is equipped with a compression spring 44 inside, and symmetrically distributed limiting rods 421 are welded to the outer surface of the sliding cylinder 42. The sliding cylinder 42 slides along the axial direction of the fixed cylinder 41, allowing the sleeve 43 to be sleeved on the outside of the heat dissipation pipe 121, thereby sealing the heat dissipation pipe 121 and preventing external dust and impurities from entering the interior of the cabinet 11 through the heat dissipation pipe 121.
[0028] In this embodiment, the limiting block 21 has a recessed limiting groove, the limiting frame 24 cooperates with the limiting groove, the limiting frame 24 and the limiting block 21 are engaged and connected, the limiting frame 24 limits the limiting block 21, thereby making the outer protective plate 13 accurately positioned, the limiting post 3 penetrates the center position of one side of the limiting frame 24, and the limiting post 3 limits the limiting frame 24.
[0029] In this embodiment, the stabilizing block 5 is welded to the inner surface of the bottom end of the outer protective plate 13. The top of the limiting post 3 has a "T" shaped structure, and the outer side of the bottom end of the limiting post 3 is provided with external threads. The bottom end of the limiting post 3 is connected to the stabilizing block 5 by threaded engagement. The limiting post 3 and the stabilizing block 5 are locked and fixed. The limiting post 3 limits the outer protective plate 13, so that the outer protective plate 13 and the cabinet 11 are installed stably.
[0030] In this embodiment, fixing blocks 132 are welded to the inner surfaces of the outer protective plate 13, and guide rails 122 are welded to the opposite surfaces of the sealing plate 12. The fixing blocks 132 are provided with rail grooves that cooperate with the guide rails 122. The guide rails 122 have a "T" shaped structure. When the outer protective plate 13 is installed in a horizontal position, the fixing blocks 132 and the guide rails 122 are slidably connected, so that the outer protective plate 13 and the fixing blocks 132 are positioned to prevent the outer protective plate 13 and the fixing blocks 132 from tilting. A limiting cylinder 131 is welded to the top surface of the outer protective plate 13. The limiting cylinder 131 serves as a positioning and limiting post 3.
[0031] In this embodiment, the outer surface of the fixed cylinder 41 is provided with a communicating annular groove a and a sliding groove b. The limiting rod 421 has an "L" shaped structure. When the limiting rod 421 is located in the annular groove a, there is a gap between the sleeve 43 and the heat dissipation pipe 121, which does not affect the translational installation of the outer protective plate 13. One end of the limiting rod 421 is inserted into the sliding groove b, and the limiting rod 421 slides along the sliding groove b. The sliding cylinder 42 is limited to prevent the sliding cylinder 42 from deflecting. The sliding cylinder 42 is provided with a spring equipped with a compression spring 44 inside. The two ends of the compression spring 44 are connected to the sliding cylinder 42 and the fixed cylinder 41 respectively. When the fixed cylinder 41 is located in the annular groove a, the compression spring 44 is in a compressed state. The sliding cylinder 42 is subjected to the elastic force of the compression spring 44, which facilitates the sliding of the sliding cylinder 42. The inner surface of the sleeve 43 is in contact with the outer surface of the heat dissipation pipe 121. The sleeve 43 is sleeved on the outside of the heat dissipation pipe 121, which plays a role in dust prevention and also has a certain sealing effect. A heat dissipation mesh plate c is welded on the surface of the sleeve 43, which does not affect heat dissipation.
[0032] Working principle and usage process of this utility model:
[0033] After the preparation work is completed, when assembling the separate cabinet 11, sealing plate 12 and outer protective plate 13, first snap the sealing plate 12 into the cabinet 11.
[0034] Then, the outer protective plate 13 is moved and installed on the outside of the sealing plate 12, and the fixing block 132 slides along the length of the guide rail 122 to position the outer protective plate 13 and the fixing block 132 and prevent the outer protective plate 13 and the fixing block 132 from tilting.
[0035] Flip the limiting frame 24 so that the limiting frame 24 engages with the limiting block 21, thereby limiting the outer protective plate 13 and making the outer protective plate 13 fit stably against the cabinet 11;
[0036] Rotate the sliding cylinder 42 and the sleeve 43 to make the limiting rod 421 leave the annular groove a on the fixed cylinder 41. The sliding cylinder 42 and the sleeve 43 slide along the axial direction of the fixed cylinder 41, and the limiting rod 421 slides along the direction of the sliding groove b. The sleeve 43 is sleeved on the outside of the heat dissipation pipe 121.
[0037] The limiting post 3 penetrates the limiting frame 24, the limiting cylinder 131, and the top of the outer protective plate 13, and is then spirally inserted into the interior of the stabilizing block 5, so that the outer protective plate 13 is limited and the outer protective plate 13 is securely installed with the cabinet 11.
[0038] In summary: The electrical control cabinet has an assembly design that facilitates easy disassembly and assembly of the cabinet housing. Both the sealing plate 12 and the outer protective plate 13 are connected to the cabinet body 11. The guide rail 122 on the sealing plate 12 is limited by the fixing block 132. The limiting post 3 passes through the limiting frame 24, the limiting cylinder 131, and the top of the outer protective plate 13 before being spirally inserted into the interior of the stabilizing block 5. The outer protective plate 13 is securely installed with the cabinet body 11, which facilitates the disassembly and assembly of the sealing plate 12 and the outer protective plate 13, and makes it convenient for rewiring and maintenance inside the cabinet body 11.
