Description

Technical Field

[0001] The utility model belongs to the technical field of electric cabinet maintenance, and particularly relates to a foldable and unfoldable electric cabinet convenient for maintenance. Background Art

[0002] In current industrial production, electric cabinets play an indispensable role. The operation of machines completely depends on the wiring and power consumption inside the electric cabinets, which are the control centers and power supply centers to ensure the normal operation of machines. Therefore, electric cabinets are very important during machine operation. However, in different production workshops, the positions where electric cabinets can be placed are different. In some workshops with sufficient space, there is still a large amount of space in front of and behind the electric cabinets for technicians to disassemble and maintain. However, in some relatively cramped workshops, the placement position of the electric cabinets causes insufficient space on the left, right, and rear for personnel to enter. Once the electrical boards inside the electric cabinets are installed, it is very difficult to disassemble them. On the one hand, it is difficult to disassemble due to the heavy weight of the wiring, and on the other hand, the completed wiring is not easy to disassemble for maintenance and then re-wire, which will result in too high maintenance costs. Therefore, too small a placement space for the electric cabinets will lead to difficulties in subsequent machine maintenance. Content of the Utility Model

[0003] To solve the above technical problems, the utility model provides a foldable and unfoldable electric cabinet convenient for maintenance. By arranging a folding and unfolding component at the bottom of the electric cabinet main body, the electrical board can enter and exit the installation cavity of the electric cabinet through the pushing of manual or cylinder, so that the electrical board can move out from the opening of the electric cabinet main body, increasing the space at the back of the electrical board, enabling technicians to repair the electrical components on the electrical board, and is especially suitable for use in workshops with insufficient installation space for electric cabinets.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A foldable electric cabinet convenient for maintenance, comprising a main body, a folding assembly and an electrical board. The electrical board is connected inside the main body through the folding assembly. The main body is an electric cabinet surrounded by a bottom frame, side plates and a top plate, and the inner cavity of the main body is an installation cavity. The folding assembly includes a fixing plate, a movable seat, a slide rail, a connecting seat and a support column. The fixing plate is detachably connected inside the bottom frame. The movable seat is movably connected to the fixing plate. The electrical board is connected to the movable seat, and the electrical board can enter and exit the installation cavity during movement. The slide rail is detachably connected to the fixing plate. A chute is provided at the bottom of the movable seat, and the chute is matched with the slide rail. The connecting seat has a U-shaped structure, and the slide rail is fitted and detachably connected at the upper opening of the connecting seat. Fixing holes are provided on the fixing plate, and the outer side wall of the connecting seat is fitted and detachably connected to the upper end surface of the fixing plate. The slide rail is detachably connected to the fixing hole through the connecting seat. One end of the support column is provided with a rotating shaft, and the movable seat is provided with a fixed shaft. The rotating shaft is rotatably connected to the fixed shaft. A support groove is provided on the lower end surface of the support column. When the support column rotates downward and forms a 90° angle with the movable seat, the support groove can be abutted and connected to the movable seat. A limiting column is provided on the movable seat. When the support column rotates upward and forms a 90° angle with the movable seat, the upper end surface of the support column abuts against the limiting column.

[0006] For the foldable electric cabinet convenient for maintenance with this structure, the main body is an electric cabinet surrounded by a bottom frame, side plates and a top plate. A detachable back plate is installed at the rear of the electric cabinet, and a cabinet door is installed at the front of the electric cabinet. It is the most commonly used electric cabinet. The inner cavity of the main body is an installation cavity for placing the electrical board. The electrical board is connected inside the main body through the folding assembly. In order to enable the electrical board to be moved out of the cabinet door through the folding assembly, a fixing plate, a movable seat, a slide rail, a connecting seat and a support column are set as a combination. The fixing plate is fixed inside the bottom frame by welding. At the same time, the upper plane of the fixing plate is flush with the bottom of the cabinet door of the main body. In order to enable translational movement, the slide rail and the movable seat are required. The slide rail is detachably connected to the fixing hole on the fixing plate through the connecting seat. The slide rail is fitted inside the U-shaped connecting seat. The outside of the connecting seat is screwed to the bottom of the slide rail through screws, and the outer contour of the connecting seat is fitted inside the fixing hole. A connecting hole is provided on the upper extension of the connecting seat, and the connecting hole corresponds to the threaded hole on the fixing plate. Therefore, after the connecting seat is fitted inside the fixing hole, it can be locked to the fixing plate from top to bottom through screws. This structure not only has simple assembly, but also can limit the front and rear positions of the slide rail, avoid the situation of front and rear movement of the slide rail during use, and its load-bearing capacity can also be enhanced.

[0007] The slide groove at the bottom of the movable seat cooperates with the slide rail, so the movable seat can be translated on the slide rail, and the length of the movable seat is basically the same as the slide rail, so the movable seat can be translated toward the direction of the cabinet door until it drives the electrical board connected to the upper end of the movable seat to move out of the cabinet door. Since the electrical components on the electrical board are very heavy, if the support force is provided by the connection between the movable seat and the slide rail alone, it will not be able to bear this weight. Therefore, when the movable seat is translated out of the slide rail, a support column is rotatably connected to the fixed axis on the movable seat through a rotating axis. When the support column is rotated downward after the movable seat is extended toward the cabinet door and is 90° with the movable seat, the end face of the support column coincides with the bottom face of the bottom frame, so that the support column can be against the ground to provide an upward supporting force for the movable seat, and the support groove on the support column is abutted against the movable seat, and the movable seat is clamped by the support groove to ensure the stability of the movable seat. Therefore, under the support of the support column, the movable seat can be extended outward for a longer distance, so that the electrical board on the movable seat can stay at different positions for technical personnel to perform internal maintenance.

[0008] After completing the unfolding and overhaul of the electrical board, it is necessary to retract the electrical board into the installation cavity and push the electrical board inward. Under the pushing force, the support groove of the support column disengages from the abutment with the movable seat until the movable seat is retracted into the installation cavity, and the support column can be rotated upward so that the support column and the movable seat are at 90°, that is, the support column can be folded upward. In order to prevent the support column from hitting the electrical board due to excessive rotation, a limit column is provided on the movable seat. The limit column can abut against the support column so that the support column and the movable seat always maintain an angle of not less than 90°.

[0009] Furthermore, the support column is provided with a through hole, and the movable seat is provided with a screw hole. When the support column is rotated downward and forms an angle of 90° with the movable seat, the through hole corresponds to the screw hole.

[0010] Compared with the prior art, the advantages of the utility model are: the slide rail can be embedded in the fixing hole on the fixing plate through the connecting seat, and the screws lock the connecting seat on the fixing plate from top to bottom. This structure is not only simple to assemble, but also can limit the front and rear positions of the slide rail, avoiding the slide rail from moving back and forth during use, and its load-bearing capacity can also be enhanced. The movable seat is movably connected to the slide rail through the sliding groove, and the support column rotatably connected to the end of the movable seat provides an upward supporting force for the end of the movable seat. The movable seat can extend outward for a longer distance, so that the electrical board on the movable seat can stay in different positions for technicians to perform internal maintenance, so that the electrical cabinet can flexibly move the electrical board in a workshop with insufficient space, providing a larger internal space for technicians to perform maintenance.

Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present invention.

[0019] The following will describe the detailed implementation manners of the present invention in conjunction with the drawings:

[0020] Such as Figures 1-5As shown in the figure, a foldable electric cabinet convenient for maintenance includes a main body 1, a folding assembly 2 and an electrical board. The electrical board is connected to the inside of the main body 1 through the folding assembly 2. The main body 1 is an electric cabinet surrounded by a bottom frame 11, side plates 12 and a top plate 13. The inner cavity of the main body 1 is an installation cavity 14. The folding assembly 2 includes a fixing plate 21, a movable seat 22, a slide rail 23, a connecting seat 24 and a support column 25. The fixing plate 21 is detachably connected to the inside of the bottom frame 11. The movable seat 22 is movably connected to the fixing plate 21. The electrical board is connected to the movable seat 22. The electrical board can enter and exit the installation cavity 14 during movement. The slide rail 23 is detachably connected to the fixing plate 21. A chute 221 is provided at the bottom of the movable seat 22. The chute 221 cooperates with the slide rail 23. The connecting seat 24 has a U-shaped structure. The slide rail 23 is fitted into the upper opening of the connecting seat 24 for detachable connection. A fixing hole 211 is provided on the fixing plate 21. The outer side wall of the connecting seat 24 is fitted into the fixing hole 211 and is detachably connected to the upper end surface of the fixing plate 21. The slide rail 23 is detachably connected to the fixing hole 211 through the connecting seat 24. One end of the support column 25 is provided with a rotating shaft 251. A fixed shaft 222 is provided on the movable seat 22. The rotating shaft 251 is rotatably connected to the fixed shaft 222. A support groove 252 is provided on the lower end surface of the support column 25. When the support column 25 rotates downward and forms a 90° angle with the movable seat 22, the support groove 252 can be abutted and connected to the movable seat 22. A limiting column 223 is provided on the movable seat 22. When the support column 25 rotates upward and forms a 90° angle with the movable seat 22, the upper end surface of the support column 25 abuts against the limiting column 223.

[0021] Further, a through hole 253 is provided on the support column 25, and a threaded hole 224 is provided on the movable seat 22. When the support column 25 rotates downward and forms a 90° angle with the movable seat 22, the through hole 253 corresponds to the threaded hole 224.

[0022] The working mode of the present utility model is described as follows:

[0023] The foldable electric cabinet with this structure is convenient for maintenance. The main body 1 is an electric cabinet enclosed by a bottom frame 11, side plates 12 and a top plate 13. A detachable back plate is installed at the rear of the electric cabinet, and a cabinet door is installed at the front end of the electric cabinet. It is the most commonly used electric cabinet. The inner cavity of the main body 1 is an installation cavity 14 for placing electrical boards. The electrical boards are connected to the main body 1 through a folding assembly 2. In order to enable the electrical boards to be moved out of the cabinet door through the folding assembly 2, a fixing plate 21, a movable seat 22, a slide rail 23, a connecting seat 24 and a support column 25 are set as a combination. The fixing plate 21 is fixed in the bottom frame 11 by welding. At the same time, the upper plane of the fixing plate 21 is flush with the bottom of the cabinet door of the main body 1. In order to be able to move horizontally, the slide rail 23 and the movable seat 22 are needed. The slide rail 23 is detachably connected to the fixing hole 211 on the fixing plate 21 through the connecting seat 24. The slide rail 23 is fitted in the U-shaped connecting seat 24. The outside of the connecting seat 24 is screwed to the bottom of the slide rail 23 through screws, and the outer contour of the connecting seat 24 is fitted in the fixing hole 211. A connecting hole is provided on the upper extension of the connecting seat 24, and the connecting hole corresponds to the threaded hole on the fixing plate 21. Therefore, after the connecting seat 24 is fitted in the fixing hole 211, it can be locked to the fixing plate 21 from top to bottom by screws. This structure not only has simple assembly, but also can limit the front and rear positions of the slide rail 23, avoid the situation of the slide rail 23 moving back and forth during use, and its load-bearing capacity can also be enhanced.

[0024] The chute 221 at the bottom of the movable seat 22 cooperates with the slide rail 23. Therefore, the movable seat 22 can move horizontally on the slide rail 23. The length of the movable seat 22 is basically the same as that of the slide rail 23. Therefore, the movable seat 22 can move horizontally in the direction of the cabinet door until the electrical board connected to the upper end of the movable seat 22 is moved out of the cabinet door. Since the electrical components on the electrical board are very heavy, if only the connection between the movable seat 22 and the slide rail 23 is relied on to provide the supporting force, this weight cannot be borne. Therefore, when the movable seat 22 moves out of the slide rail 23, a support column 25 is rotatably connected to the fixed shaft 222 on the movable seat 22 through a rotating shaft 251. When the support column 25 rotates downward and forms a 90° angle with the movable seat 22 after the movable seat 22 extends out of the cabinet door, the end face of the support column 25 coincides with the bottom surface of the bottom frame 11. Therefore, the support column 25 can resist the ground and provide an upward supporting force for the movable seat 22, and the support groove 252 on the support column 25 abuts against the movable seat 22, and the movable seat 22 is clamped through the support groove 252 to ensure the stability of the movable seat 22. Therefore, under the support of the support column 25, the movable seat 22 can extend out a longer distance, so that the electrical board on the movable seat 22 can stay at different positions for technicians to perform internal maintenance.

[0025] After the electrical board is unfolded and repaired, it is necessary to retract the electrical board into the installation cavity 14. Push the electrical board inward. Under the driving force, the support column 25 disengages from the abutment with the movable seat 22 in the support groove 252 until the movable seat 22 retracts into the installation cavity 14. The support column 25 can rotate upward so that the support column 25 forms a 90° angle with the movable seat 22, that is, the support column 25 can be folded upward. To prevent the support column 25 from hitting the electrical board due to excessive rotation, a limit post 223 is provided on the movable seat 22. The limit post 223 can abut against the support column 25 so that the support column 25 and the movable seat 22 always maintain an angle of not less than 90°. Since pushing the electrical board into the installation cavity 14 will cause the support column 25 to lose its supporting effect, if the electrical board is accidentally pushed during the repair process, without being supported or pulled by someone, a downward pressure will suddenly be generated at the end of the movable seat 22, which will cause minor damage to the movable seat 22 at worst, and at worst, it will cause the electrical board to tilt and be smashed, resulting in greater losses. Therefore, a through hole 253 is provided on the support column 25, and a threaded hole 224 is provided on the movable seat 22. When the support column 25 rotates downward to form a 90° angle with the movable seat 22, the through hole 253 corresponds to the threaded hole 224, and the support column 25 and the movable seat 22 can be fixed by screwing in a screw, avoiding the loss of support force of the movable seat 22 when the electrical board is pushed. After the repair is completed, unscrew the screw, and the electrical board can be pushed into the installation cavity 14 for retraction.

[0026] The beneficial effects of the present utility model are as follows: The slide rail 23 can be fitted into the fixing hole 211 on the fixing plate 21 through the connecting seat 24, and the connecting seat 24 is locked on the fixing plate 21 by screws from top to bottom. This structure is not only simple to assemble, but also can limit the front and rear positions of the slide rail 23, avoiding the situation of front and rear movement of the slide rail 23 during use, and its load-bearing capacity can also be enhanced. The movable seat 22 is movably connected to the slide rail 23 through the sliding groove 221, and the support column 25 rotatably connected to the end of the movable seat 22 provides an upward support force for the end of the movable seat 22. The movable seat 22 can extend outward for a longer distance, so that the electrical board on the movable seat 22 can stay at different positions for technicians to perform internal repairs. In a workshop with insufficient space, the electrical board of this electric cabinet can be flexibly moved to provide a larger internal space for technicians to perform repairs.

[0027] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
