It should be understood that the specific embodiments described here are only used to explain this disclosure, and are not used to limit this disclosure.
As shown in
Two supporting frame 2 are respectively arranged on the bottom of inner walls on two sides of box body 1; upper mounting plate 3 is mounted into mounting location 221 of supporting frame 2 from the entrance of mounting location 221, and fixing plate 4 is mounted on the entrance of mounting location 221 to seal the entrance of mounting location 221 and prevent upper mounting plate 3 from sliding out from mounting location 221. Hence, for upper mounting plate 3, upper mounting plate 3 can be mounted on box body 1 by means of supporting frames 2 on the bottom of two sides of box body 1. Meanwhile, upper mounting plate 3 is flippable relative to mounting location 221; therefore, by means of rotating upper mounting plate 3, relative movement occurs between upper mounting plate 3 and box body 1 so as to expose electric elements shielded by upper mounting plate 3 and facilitate maintenance and replacement of electric elements inside the electric cabinet; and it has a simple structure and convenient operation.
In an embodiment, as shown in
Hence, it can prevent upper mounting plate 3 from rubbing and colliding with an inner wall of box body 1 and damage the inner wall of box body 1 when rotating or moving. Second straight plate 224 of main body portion 22 is bent to form first flanging 21, and first flanging 21 is connected to box body 1, thus facilitating assembly and fixation of supporting frame 2 and box body 1. As shown in
In an embodiment, supporting frames 2 are arranged on the bottom of inner walls on two sides of box body 1; two sides of upper mounting plates 3 are bent to form second flanging 33; connecting plate 32 is arranged on two ends of the bottom of upper mounting plate 3; connecting plate 32 and second flanging 33 are arranged in a same direction; rotation shaft 31 runs through connecting plate 32 and second flanging 33; fixing positions 311 are arranged on two ends of rotation shaft 31, and a portion between fixing portion 311 close to second flanging 33 on rotation shaft 31 and second flanging 33 is mounted on mounting location 221.
Two supporting frames 2 are arranged on the bottom of inner walls on two sides of box body 1; upper mounting plates 3 are mounted on supporting frame 2 from two ends of the bottom, so as to facilitate that upper mounting plate 3 rotates by taking the bottom side as a shaft. Two sides of upper mounting plate 3 are bent to form second flanging 33; second flanging 33 and connecting plate 32 are arranged in a same direction, and rotation shaft 31 penetrates therethrough, so as to make upper mounting plate 3 be capable of flipping when the bottom side is mounted to supporting frame 2. Fixing portions 311 are arranged on two ends of rotation shaft 31. Generally, the area of the cross section connecting fixing portion 311 and rotation shaft 31 is larger than the area of the cross section of rotation shaft 31 so that when rotation shaft 31 penetrates between second flanging 33 and connecting plate 32, it will not fall off connecting plate 32 and second flanging 33. When rotation shaft 31 penetrates between second flanging 33 and connecting plate 32, the length of rotation shaft 31 is larger than the distance between second flanging 33 and connecting plate 32, so that a gap may be formed between fixing portion 311 close to second flanging 33 and second flanging 33, and a portion between fixing portion 311 close to second flanging 33 on rotation shaft 31 and second flanging 33 can be mounted on mounting location 221. The mounting manners of two ends on the bottom of upper mounting plate 3 are totally the same, so as to make upper mounting plate 3 be mounted on supporting frame 2.
In an embodiment, mounting location 221 is a U-shaped groove. An entrance of mounting location 221 is communicated with the U-shaped groove. The longest straight line of a contact surface between fixing portion 311 close to second flanging 33 and first straight plate 223 of main body portion 22 is greater than the width of the U-shaped groove.
Mounting location 221 is set as a U-shaped groove, so that the end of mounting location 221 can be closer to the curvature of the outer circumference of rotation shaft 31, not damaging rotation shaft 31 during mounting and fixing. The longest straight line of a contact surface between fixing portion 311 close to second flanging 33 on rotation shaft 31 and first straight plate 223 of main body portion 22 is greater than the width of the U-shaped groove, so that fixing portion 311 will not penetrate through the U-shaped groove, rotation shaft 31 can be mounted on the U-shaped groove and will not fall off.
In an embodiment, fixing plate 4 is L-shaped; a longitudinal plate of fixing plate 4 is inserted into a gap between first straight plate 223 of main body portion 22 and second flanging 33; first screw thread hole 41 used to fix fixing plate 4 is arranged on a horizontal plate of fixing plate 4; second screw thread hole 222 corresponding to first screw thread hole 41 is further arranged on second straight plate 224 of main body portion 22; fixing plate 4 is sequentially inserted into first screw thread hole 41 and second screw thread hole 222 by means of screw bolt 5 to fix fixing plate 4 on supporting frame 2.
Fixing plate 4 is set as L-shaped so that fixing plate 4 can fix upper mounting plate 3 on supporting frame 2 when being inserted into the gap. First screw thread hole 41 used to fix fixing plate 4 is arranged on a horizontal plate of fixing plate 4; second screw thread hole 222 corresponding to first screw thread hole 41 is arranged on second straight plate 224 of main body portion 22; by means of merely rotating screw bolt 5, only first screw thread hole 41 and second screw thread hole 222 may lock fixing plate 4 on supporting frame 2. Meanwhile, since fixing plate 4 is L-shaped, the longitudinal plate thereof is inserted into the gap between second straight plate 224 of main body portion 22 and second flanging 33, and can abut against rotation shaft 31 and prevent it from sliding out. Therefore, by means of fixing plate 4 and screw bolt 5, mounting of upper mounting plate 3 and supporting frame 2 and mounting of fixing plate 4 and supporting frame 2 can be realized.
In an embodiment, recessed portion 42 fit with rotation shaft 31 is arranged on the longitudinal plate of fixing plate 4.
Recessed portion 42 is arranged, and can fit with the curvature of the outer circumferential surface of rotation shaft 31 when the longitudinal plate of fixing plate 4 is inserted into the gap between second straight plate 224 of main body portion 22 and second flanging 33 to abut against rotation shaft 31, so that rotation shaft 31 is not damaged when the longitudinal plate of fixing plate 4 abuts against rotation shaft 31.
In an embodiment, both the quantity of first screw thread hole 41 and second screw thread hole 222 is two, and two first screw thread holes 41 respectively correspond to two second screw thread holes 222. Fixing plate 4 is sequentially inserted into first screw thread hole 41 and second screw thread hole 222 by means of two screw bolts 5 to fix fixing plate 4 on supporting frame 2.
Two screw thread holes are arranged on second straight plate 224 of main body portions of fixing plate 4 and supporting frame 2. Two screw bolts 5 are sequentially inserted into first screw thread hole 41 and second screw thread hole 222 to fix supporting frame 2 and the mounting plate, which is more stable than using single screw bolt 5.
In an embodiment, the recessed portion of the longitudinal plate of fixing plate 4 abuts against rotation shaft 31, and upper mounting plate 3 rotates around rotation shaft 31.
The longitudinal plate of fixing plate abuts against rotation shaft 31 by means of recessed portion 42, and can clamp rotation shaft 31 between the bottom edge of the longitudinal plate of fixing plate 4 and the bottom of the U-shaped groove. In the prior art, the mounting structure of electronically controlled sheet metal components is not compact, which easily causes the components to collide with each other and generate noise. If the length of the longitudinal plate of fixing plate 4 is long enough to abut against rotation shaft 31, so that the edge of the longitudinal plate of fixing plate 4 and the bottom of the U-shaped groove cannot form a large gap, thereby avoiding the collision of rotation shaft 31 moving back and forth in this gap to damage rotation shaft 31, and also avoiding the noise caused by the collision of sheet metal during the transportation of the machine, which is simple for production and maintenance operations and improves efficiency.
In an embodiment, two supporting frames 2 arranged on the upper portion of inner walls on two sides of box body 1 are included. Third screw thread hole corresponding to second screw thread hole 222 is arranged on two ends of the upper portion of upper mounting plate 3. Upper mounting plate 3 is sequentially inserted into third screw thread hole and second screw thread hole 222 by means of screw bolt 5 to fix upper mounting plate 3 on supporting frames 2 on upper portions of inner walls on two sides of the box body.
Two supporting frames 2 are arranged on the upper portion of inner walls on two sides of box body 1. Second screw thread hole 222 is arranged on supporting frame 2. Upper mounting plate 3 is rotated to a corresponding position after the maintenance is completed. Third screw thread holes on two ends of the upper portion of upper mounting plate 3 are aligned with second screw thread hole 222 on supporting frame 2. By rotating screw bolt 5 into second screw thread hole 222 and third screw thread hole, the upper portion of upper mounting plate 3 can be mounted on box body 1. When mounting, debugging and maintaining, screw bolts 5 on two ends of the upper portions of upper mounting plate 3 are disassembled, and upper mounting plate 3 is flipped down to facilitate debugging and maintenance of components. After mounting, debugging, and maintenance are completed, upper mounting plate 3 is rotated to the initial position, and is fixed by means of the third screw thread hole on the upper portion of upper mounting plate 3. The operation is simple.
This disclosure further provides an air conditioner including the above outdoor unit electric cabinet.
In an outdoor unit electric cabinet of an air conditioner and an air conditioner with the outdoor unit electric cabinet provided by this disclosure, when being mounted, debugged, and maintained, electronically controlled upper mounting plate 3 does not need to be disassembled. By means of rotation shaft 31, opening, closing, and mounting of upper mounting plate 3 of the electric cabinet is convenient and fast. When being mounted, debugging, and maintaining, upper mounting plate 3 rotates around rotation shaft 31 and flips up and down. After mounting, debugging and maintenance are completed, it is fixed through the screw thread holes on the upper portions of upper mounting plate 3 to ensure that four corners of upper mounting plate 3 are fixed. Fixing plate 4 clamps rotation shaft 31 to avoid the noise caused by the collision of sheet metal during the transportation and operation of the machine, and the production and maintenance operations are simple, and the efficiency is improved.
