Technical Field

[0001] This utility model relates to the field of power supply installation structure technology, specifically a modular installation and fixing structure for power supplies. Background Technology

[0002] A power supply is a device that converts other forms of energy into electrical energy and provides electrical energy to circuits (electronic devices). When the power supply is installed inside the distribution cabinet, the power supply equipment (such as switching power supply) is directly fixed to the cabinet structure of the distribution cabinet by bolts, nuts and other connectors. Usually, brackets or mounting plates are pre-installed inside the distribution cabinet. The power supply equipment is tightly connected to these fixed structures to ensure that it remains stable during operation.

[0003] While this installation method can ensure the stability of the connection between the power supply and the distribution cabinet, it has poor structural flexibility. If the power supply equipment needs to be replaced, upgraded or repaired later, multiple bolts and other connecting parts need to be disassembled. Furthermore, wrenches and other tools are required during the installation and disassembly process, making the operation cumbersome. Therefore, a modular installation and fixing structure for the power supply is needed to solve the above technical problems. Utility Model Content

Detailed Implementation

[0029] The present invention will now be further described with reference to the accompanying drawings.

[0030] like Figures 1 to 7 As shown, a modular power supply mounting and fixing structure includes a power module body 10. Positioning pads 20 are fixedly connected to two symmetrical sides of the power module body 10. Multiple positioning through holes 21 are provided on one side of each positioning pad 20. Fixing base plates 30 are provided on both sides of the power module body 10. Support grooves 31 are provided on the top side of the fixing base plates 30. The positioning pads 20 and support grooves 31 can position the power module body 10, preventing movement along its length. The support grooves 31 support and position the positioning pads 20. The depth of the support grooves 31... The thickness of the support groove 31 is the same as that of the positioning pad 20. A positioning insertion hole 32 is provided in the middle of the inner wall of the support groove 31. A fixing plate 40 is fixedly connected to the top side of the fixing base plate 30. A fixing insertion hole 41 is provided on one side of the fixing plate 40. Movable connecting plates 50 are provided on two symmetrical sides of the power module body 10. The moving direction of the connecting plate 50 is parallel to the width direction of the power module body 10. A positioning connector and a fixing component are provided on the connecting plate 50. The positioning connector is used to connect the positioning pad 20, the fixing base plate 30 and the connecting plate 50. The fixing component is connected to the positioning connector and is used to connect the fixing plate 40 and the connecting plate 50.

[0031] It should be noted that the base plate 30 has bolt holes, and the base plate 30 is installed in a suitable position inside the distribution cabinet by means of bolt holes and bolts.

[0032] like Figure 1 , Figure 2 , Figure 4 and Figure 6The positioning connector includes a spring 51 connected to the connecting plate 50. A movable block 52 is fixedly connected to the top of the spring 51, and a positioning rod 53 is fixedly connected to the bottom side of the movable block 52. The positioning rod 53 passes through the connecting plate 50 and is slidably connected to the connecting plate 50. The size of the positioning rod 53 is adapted to the size of the positioning through hole 21 and the positioning hole 32. The positioning rod 53 passes through the inside of the positioning through hole 21 and is inserted into the inside of the positioning hole 32. The fixing component includes a guide formed on the top side of the connecting plate 50. The inner wall of the guide groove 54 is fixedly connected to a guide rod 55 and a second spring 56. The outer surface of the guide rod 55 is slidably connected to a slider 57 connected to the second spring 56. The slider 57 is T-shaped. The bottom end of the slider 57 is located inside the guide groove 54 and is slidably connected to the guide groove 54. A connecting rod 58 is hinged to one side of the slider 57. The top end of the connecting rod 58 is hinged to the movable block 52. A fixing rod 59 is fixedly connected to the side of the slider 57 away from the connecting rod 58. The fixing rod 59 is inserted into the inside of the fixing hole 41.

[0033] When adjusting and positioning the connecting plate 50, pull the movable block 52 upward to move the positioning rod 53 out of the positioning through hole 21. At this time, the spring 1 51 is in a stretched state. During the movement of the movable block 52, the connecting rod 58 drives the slider 57 to move along the guide groove 54 and squeeze the spring 2 56. Then, by moving the movable block 52, the connecting plate 50 is moved. Adjust the connecting plate 50 to a suitable position according to the position of the fixed base plate 30, and make the fixed rod 59 correspond to the position of the fixed insertion hole 41. At this time, the positioning rod 53 is aligned with a positioning through hole 21 and the positioning insertion hole. When positions 32 correspond, the movable block 52 can be released. Under the reaction force of spring 1 51 and spring 2 56, the fixed plug 59 and the positioning plug 53 are reset, so that the fixed plug 59 is inserted into the fixed plug hole 41, and the positioning plug 53 passes through a positioning through hole 21 and is inserted into the positioning plug hole 32, thereby fixing the connecting plate 50. At this time, the power module body 10 is also fixed, completing the operation of installing the power module body 10. This makes the operation of installing the power module body 10 relatively simple. Similarly, it is easy to remove the power module body 10 and replace, upgrade or repair the power module body 10.

[0034] It should be noted that a portion of the guide rod 55 is located inside the second spring 56. The guide rod 55 guides and limits the second spring 56, ensuring that the second spring 56 can only undergo elastic deformation along the direction of the guide rod 55, thus preventing the second spring 56 from bending during the elastic deformation process.

[0035] like Figure 3 , Figure 5 and Figure 7A positioning adjustment assembly is provided between the power module body 10 and the fixed base plate 30. The positioning adjustment assembly is used to position the fixed base plate 30. The positioning adjustment assembly includes multiple positioning grooves 11 opened on the bottom side of the power module body 10 and an adjustable length positioning plate assembly connected to the fixed base plate 30. The positioning plate assembly is snapped into the inside of the positioning groove 11. The positioning plate assembly includes a hollow plate 33 connected to two fixed base plates 30. An extension plate 34 is slidably connected inside the two hollow plates 33. Two locking threaded rods 35 are fixedly connected to one side of the extension plate 34. A butterfly locking nut 36 is threaded to the outer surface of the two locking threaded rods 35. A through groove 37 is opened on one side of each of the two hollow plates 33. The locking threaded rod 35 passes through the inside of the through groove 37 and is slidably connected to the through groove 37.

[0036] Before fixing the power module body 10, the distance between the two fixing base plates 30 needs to be adjusted first. By moving the two fixing base plates 30, the hollow plate 33 is moved. At this time, the extension plate 34 is moved out from the inside of the hollow plate 33. The distance between the two fixing base plates 30 is adjusted to a suitable distance according to the length of the power module body 10. Then, the butterfly locking nut 36 is rotated to fit tightly with the hollow plate 33, thereby fixing the extension plate 34. The distance between the two fixing base plates 30 is kept to a suitable distance. Then, the fixing base plates 30 are installed in a suitable position inside the power distribution cabinet with bolts to facilitate the subsequent installation and disassembly of the power module body 10.

[0037] It should be noted that a scale value can be set on the hollow plate 33, and the scale value corresponds to the position of the locking threaded rod 35. By observing the scale value, the distance between the two fixed base plates 30 can be more clearly understood, so that the distance between the two fixed base plates 30 can be adjusted more accurately and quickly to a suitable distance. The width of the hollow plate 33 is adapted to the width of the positioning groove 11, and the thickness of the hollow plate 33 is adapted to the depth of the positioning groove 11, so that the hollow plate 33 can be fully inserted into the interior of the positioning groove 11.

[0038] like Figure 1-3 The power module body 10 has guide components on two symmetrical sides. The guide components are connected to the connecting plate 50. The guide components are used to move the connecting plate 50 along the width direction of the power module body 10. The guide components include a guide rail 12 connected to the power module body 10. The length direction of the guide rail 12 is parallel to the width direction of the power module body 10. A slide block 13 connected to the connecting plate 50 is slidably connected to the guide rail 12. The guide rail 12 and the slide block 13 will not separate, ensuring that the slide block 13 can drive the connecting plate 50 to move stably along the length direction of the guide rail 12.

[0039] like Figure 5The inner wall of the support groove 31 is fixedly connected with two positioning pins 311. The diameter of the positioning pins 311 is matched with the diameter of the positioning through hole 21. The positioning pins 311 are inserted into the inside of the positioning through hole 21. The positioning pad 20 can be positioned by the positioning pins 311 and the positioning through hole 21 to prevent the positioning pad 20 from moving along the width direction of the power module body 10.

[0040] It should be noted that the spacing between two adjacent positioning holes 21 is the same as the spacing between two adjacent positioning grooves 11, so that the hollow plate 33 can be inserted into the positioning groove 11 at the same time as the positioning pin 311 is inserted into the positioning hole 21.

[0041] The top side of the movable block 52 is threaded with a lifting handle, which allows the movable block 52 to be moved easily by pulling.

[0042] The working principle of the power module body 10 is as follows:

[0043] 1) Adjust the distance between the two fixed base plates 30 to a suitable level according to the length of the power module body 10, and install the fixed base plates 30 in a suitable position inside the power distribution cabinet;

[0044] 2) Insert the positioning pin 311 into the positioning through hole 21 at the appropriate position. At this time, the positioning pad 20 is inserted into the support groove 31 and fits tightly against the inner wall of the support groove 31, thereby positioning the power module body 10 and preventing the power module body 10 from shifting position.

[0045] 3) Pull the movable block 52 upward to make it move the positioning rod 53 out of the inside of a positioning through hole 21. At this time, the spring 1 51 is in a stretched state. During the movement of the movable block 52, the connecting rod 58 drives the slider 57 to move along the direction of the guide groove 54 and squeeze the spring 2 56.

[0046] 4) Move the movable block 52 to drive the connecting plate 50 to move. Adjust the connecting plate 50 to a suitable position according to the position of the fixed base plate 30, and make the fixed insertion rod 59 correspond to the position of the fixed insertion hole 41. At this time, the positioning insertion rod 53 corresponds to the position of a positioning through hole 21 and a positioning insertion hole 32.

[0047] 5) Loosen the movable block 52. Under the reaction force of spring 1 51 and spring 2 56, the fixed plug rod 59 and the positioning plug rod 53 are reset, so that the fixed plug rod 59 is inserted into the fixed plug hole 41 and the positioning plug rod 53 passes through a positioning through hole 21 and is inserted into the positioning plug hole 32, thus fixing the connecting plate 50 and completing the installation operation of the power module body 10.
