Description

Technical Field

[0001] This utility model relates to the field of rectifier technology, specifically to a rectifier that is easy to maintain. Background Technology

[0002] A rectifier is a device that converts alternating current (AC) to direct current (DC). It can be used in power supply devices and for detecting radio signals. Rectifiers can be made from vacuum tubes, ignition tubes, solid silicon semiconductor diodes, mercury arc diodes, etc. Conversely, a device that converts DC to AC is called an inverter. In a standby UPS, only the battery needs to be charged, not the load, so only a charger is needed. In a double-conversion UPS, this device supplies power to the inverter and charges the battery, hence it is called a rectifier / charger. However, in current rectifiers, the protective casing is installed with multiple bolts, which makes internal maintenance inconvenient. Therefore, we propose a rectifier that is easier to maintain to solve the above problems. Utility Model Content

[0021] 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.

[0022] Example

[0023] like Figure 1 , Figure 2 and Figure 3As shown in the figure, an embodiment of the present invention provides a rectifier that is easy to maintain, including a rectifier base 1. Two mounting blocks 15 are fixed to both side walls of the rectifier base 1. The top of each mounting block 15 is provided with a mounting hole, which makes it easier to install and fix the rectifier. A housing 2 is attached to the top of the rectifier base 1. Lower L-shaped blocks 3 are fixed to both side walls of the rectifier base 1. Fixing holes 4 are provided on the side walls of the lower L-shaped blocks 3. Upper L-shaped blocks 5 that are adapted to the lower L-shaped blocks 3 are fixed to both side walls of the housing 2. A connecting rod 6 slides through the side wall of each upper L-shaped block 5. One end of each connecting rod 6 is fixed with a... Fixing blocks 7 are adapted to the fixing holes 4 and are respectively inserted into the corresponding fixing holes 4. A spring 18 is fixed to one side wall of each fixing block 7, and the other end of the spring 18 is fixedly connected to the corresponding upper L-shaped block 5. A transmission assembly 8 is provided on the housing 2 to drive the two connecting rods 6 to move in opposite directions simultaneously. Air inlets 9 are provided on both side walls of the housing 2, and cotton cloth layers 17 are fixed inside each air inlet 9. The cotton cloth layers 17 can filter the moisture in the incoming air, preventing humid air from entering the housing 2. Mounting frames 10 are fixed to each air inlet 9. Each slot 10 has a filter screen 11 tightly inserted inside. An exhaust fan 12 is fixed inside the opening at the top of the housing 2. A protective cover 16 is fixed above the exhaust fan 12 and fixed to the top of the housing 2, providing dust protection for the exhaust fan 12. When using this rectifier, starting the exhaust fan 12 draws outside air into the housing 2 through the air inlet 9, dissipates heat inside, and then exhausts it, thus accelerating the internal heat dissipation speed. The filter screen 11 serves as a dust preventer, and with the cooperation of the mounting frame 10, the filter screen 11 can be easily removed for cleaning. When it is necessary to separate the housing 2 from the rectifier base 1, the transmission component 8 can be operated to drive the two connecting rods 6 to move in opposite directions simultaneously. When the connecting rods 6 move, they will drive the fixing blocks 7 to move respectively. When the fixing blocks 7 move, the spring 18 will be in a compressed state, and the fixing blocks 7 will slide out from the inside of the fixing hole 4. At this time, the housing 2 can be removed. During installation, the above operation is repeated. After the housing 2 is installed on the top of the rectifier base 1, the transmission component 8 is released. Then, under the restoring force of the compressed spring 18, the fixing blocks 7 can be re-inserted into the inside of the fixing hole 4, and the two can be connected and fixed.

[0024] like Figure 4As shown, the transmission assembly 8 used to drive the two connecting rods 6 to move in opposite directions simultaneously in this utility model also has another form, which mainly includes a connecting seat 19 fixed to the top of the housing 2. A pressure plate 20 is provided above the connecting seat 19. Two connecting rods 21 are rotatably connected to the bottom of the pressure plate 20 through a pin. One end of each connecting rod 6 is fixed with a connecting block 22. The bottom end of the connecting rod 21 is rotatably connected to the corresponding connecting block 22 through a pin. In use, the pressure plate 20 can be pressed with the cooperation of the connecting seat 19. After the pressure plate 20 moves, the connecting block 22 can be driven to move in opposite directions with the cooperation of the two connecting rods 21. Therefore, it is possible to drive the two connecting rods 6 to move in opposite directions.

[0025] like Figure 1 and Figure 3 As shown, in some embodiments, the transmission assembly 8 includes an auxiliary seat 801 fixed to the top of the housing 2. A movable plate 802 is provided below the auxiliary seat 801. Two limiting blocks 803 are fixed to the surface of each upper L-shaped block 5. A steel wire rope 804 is wound around the surface of two adjacent limiting blocks 803. The top ends of the steel wire ropes 804 are fixedly connected to the movable plate 802, and the bottom ends of the steel wire ropes 804 are fixedly connected to the corresponding connecting rods 6. In use, with the cooperation of the auxiliary seat 801, the movable plate 802 can be pulled upward. After the movable plate 802 moves upward, it can drive the steel wire ropes 804 to move upward. Finally, with the cooperation of the limiting blocks 803, the two connecting rods 6 can be driven to move in opposite directions.

[0026] like Figure 2 and Figure 3 As shown, in some embodiments, the top of the rectifier base 1 is provided with a guide groove 13, and the bottom of the housing 2 is fixed with a guide frame 14 that is adapted to the guide groove 13. When the housing 2 is connected to the rectifier base 1, it can play a guiding and limiting role so that the fixing block 7 can be accurately inserted into the inside of the fixing hole 4.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
