Description

Technical Field

[0001] This utility model relates to an internal device of a chassis, and more particularly to a suspended power supply box. Background Technology

[0002] For large equipment or circuit modules, a large chassis is usually used for control. The chassis integrates the control circuits of each sub-module and the corresponding power supply box. The traditional method of installing power supply boxes is to use screws to directly fix different power supply boxes to the chassis. However, when performing maintenance, the screws need to be completely loosened before the power supply box can be removed. Since there are many power supply boxes in the chassis, if multiple power supply boxes need to be maintained, there is a problem of long disassembly and assembly time, which reduces work efficiency. Utility Model Content

[0003] Therefore, it is necessary to provide a suspended power supply box to address the shortcomings of existing technologies.

[0004] A suspended power supply box is mounted on a chassis.

[0023] Please see Figures 1 to 4 This utility model provides a suspended power supply box 100, which is installed on a chassis 200. The chassis 200 is provided with two side plates 201 arranged opposite to each other, a back plate 202 disposed between the two side plates 201, a first support rod 203 and a second support rod 204 installed on the two side plates 201, and a crossbeam 205 installed on the back plate 202. The first support rod 203 is flush with the height of the crossbeam 205, and the second support rod 204 is disposed above the space between the first support rod 203 and the crossbeam 205.

[0024] The suspended power box 100 includes a first housing 10, a second housing 20, a support frame 30, a first connector connecting the first housing 10 and the second housing 20, and a second connector 40 connecting the second housing 20 and the support frame 30. The support frame 30 can be adjusted back and forth on the second housing 20.

[0025] The first housing 10 includes a bottom shell 11 and a first surrounding plate 12 connected to the bottom shell 11. There are two first surrounding plates 12. The bottom of the two first surrounding plates 12 are respectively connected to the front and rear sides of the bottom shell 11. The bottom shell 11 has a first buckle 111 protruding upward at the side edges. The first surrounding plate 12 has a second buckle 121 protruding inward at the side edges and the top edge away from the bottom shell 11. The first surrounding plate 12 has an avoidance opening 122 at the middle of the top edge.

[0026] The second housing 20 includes a front shell 21 and two second surrounding plates 22 connected to the front shell 21. The bottoms of the two second surrounding plates 22 are respectively connected to the left and right sides of the bottom shell 11. The front shell 21 is provided with adjustment holes 212 and fixing holes 211. In this embodiment, there are two fixing holes 211. The two fixing holes 211 are located at the front and rear edges of the front shell 21, and the adjustment hole 212 is located between the two fixing holes 211. The adjustment hole 212 and the fixing hole 211 are arranged in the front and rear direction.

[0027] The support frame 30 includes a plate body 31, a first hook 32 and a second hook 33 connected to the plate body 31. The plate body 31 is flat and has a first guide hole 311 and a second guide hole 312. Both the first guide hole 311 and the second guide hole 312 are elongated holes. The plate body 31 also has a functional hole 313 between the first guide hole 311 and the second guide hole 312. The first hook 32 is connected to the tail end of the plate body 31, and the second hook 33 is connected to the wall of the functional hole 313.

[0028] During assembly, the plate body 31 of the support frame 30 is installed on the clearance opening 122 of the two first surrounding plates 12. The first hook 32 and the locking end 314 of the support frame 30 extend from the two first surrounding plates 12 respectively. The end of the plate body 31 away from the first hook 32 is the locking end 314. The second housing 20 is fastened to the first housing 10. The first buckle 111 and the second buckle 121 on the first housing 10 are in contact with the inner side of the second housing 20. Part of the first connecting piece passes through the second housing 20 and is installed and fixed with the first buckle 111. Part of the first connecting piece passes through the second housing 20 and is installed and fixed with the second buckle 121.

[0029] The second hook 33 extends from the adjustment hole 212 of the second housing 20. The two fixing holes 211 of the second housing 20 are aligned with the first guide hole 311 and the second guide hole 312, respectively. The second connector 40 is a rivet. One of the second connectors 40 passes through the fixing hole 211 and the first guide hole 311 in the middle, and the two ends of the second connector 40 are respectively locked at the openings of the fixing hole 211 and the first guide hole 311. The other second connector 40 passes through the fixing hole 211 and the second guide hole 312 in the middle, and the two ends of the second connector 40 are respectively locked at the openings of the fixing hole 211 and the second guide hole 312. The support frame 30 can be adjusted back and forth to adjust the position of the first hook 32, the second hook 33, and the locking end 314 on the plate body 31, so as to facilitate the installation of the suspended power box 100 on the chassis 200.

[0030] When the suspended power supply box 100 is installed on the chassis 200, the first hook 32 is fastened to the first support rod 203, the second hook 33 is fastened to the second support rod 204, and the locking end 314 on the main body 31 abuts against the crossbeam 205. The first hook 32, the second hook 33 and the locking end 314 support the suspended power supply box 100 from different positions. On the one hand, this can reduce the deformation of the main body 31. On the other hand, it can distribute the pressure generated by the weight of all power supply boxes in the chassis 200 to the first support rod 203, the second support rod 204 and the crossbeam 205.

[0031] The beneficial effects of the suspended power box 100 of this utility model are as follows: by setting a support frame 30 on the suspended power box 100, and setting a first hook 32, a second hook 33 and a locking end 314 on the support frame 30, when the suspended power box 100 is installed on the chassis 200, the first hook 32 is fastened to the first support rod 203, the second hook 33 is fastened to the second support rod 204, and the locking end 314 on the main body 31 abuts against the crossbeam 205, thereby realizing the quick installation and removal of the suspended power box 100 on the chassis 200, which is convenient for maintenance.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
