Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of electrical control, specifically relating to a control box for a supply and return oil pump. Background Technology
[0002] In numerous fields such as petrochemicals, power generation, and industrial manufacturing, the supply and return oil pump control box plays a crucial role. It precisely controls the operation of the supply and return oil pumps, ensuring the stable operation of the fluid transport system. With the continuous improvement of industrial automation, the performance and reliability requirements for the supply and return oil pump control box are becoming increasingly stringent.
[0003] Currently, there is a significant structural design problem with supply and return oil pump control boxes on the market. When equipment maintenance requires opening and closing the box door, wiring cables often become caught between the door and the box body. Because the gap between the door and the box body is relatively small, and the cables need to connect to different electrical components inside and outside the box, their wiring often passes through the area where the door opens and closes. During frequent opening and closing of the box door, the cables are easily squeezed by the door and the box body. This cable entrapment is not accidental but is quite common in the daily use and maintenance of control boxes. Once the cable is trapped, its insulation layer will be damaged to varying degrees, which will not only affect the electrical performance of the cable itself but also reduce the stability of signal transmission. Therefore, a supply and return oil pump control box is provided to solve the above-mentioned technical problem. Utility Model Content
[0004] To address the problem in existing oil supply and return pump control boxes where wiring cables can easily get caught in the gap between the door and the box body during maintenance of internal electrical components, affecting cable lifespan, this invention provides an oil supply and return pump control box. Adapter block A and adapter block B are respectively installed inside the box body and on the door. Adapter block A has a vertical rod with a spring clip, and a hinge rod is installed between adapter block A and adapter block B. When opening the door, the adapter block A can be pulled to the left using the coordinated action of hinge block B and the hinge rod; when closing the door, adapter block A can be pushed to the right. During wiring operations, cables connecting the electrical components on the door to those inside the control box body can be neatly stored in the cable management slots of the spring clip. During the closing process, the cable moves to the right along with adapter block A, moving it away from the gap between the door and the control box body. This prevents cable clamping and ensures the cable's normal service life. This effectively solves the problem in existing oil pump control boxes where, during maintenance of internal electrical components, cables are easily caught in the gap between the door and the box body when opening and closing the door, affecting the cable's lifespan. The specific technical solution is as follows:
[0005] A supply and return oil pump control box includes a main body and a door. The door is rotatably mounted in front of the main body. A slider is slidably mounted on the lower surface of the inner cavity of the main body. A transition block A is fixedly mounted on the upper surface of the slider. A transition block B is fixedly mounted on the side of the door used for installing electrical components. A hinge rod is rotatably mounted between transition block B and transition block A. A vertical rod is fixedly mounted on the upper surface of transition block A. Multiple elastic clips are snapped onto the outer surface of the vertical rod. Each elastic clip has a wire harness slot on its right surface. A lighting lamp that automatically turns on when the door is opened is fixedly mounted on the upper surface of the inner cavity of the main body.
[0006] In the above technical solution, two L-shaped limiting plates are fixedly installed on the lower surface of the inner cavity of the main body of the oil supply and return pump control box. The two L-shaped limiting plates are assembled with the lower surface of the inner cavity of the main body of the oil supply and return pump control box to form a sliding groove, and the slider is slidably installed in the sliding groove.
[0007] In the above technical solution, both the adapter block A and the adapter block B are provided with adapter grooves, and both ends of the hinge rod are fixedly installed with hinge plates. The two hinge plates are respectively located in the corresponding adapter grooves, and the adapter block A and the adapter block B are respectively installed with hinge shafts between them and the corresponding hinge plates.
[0008] In the above technical solution, an insulating shell is fixedly installed on the left side of the inner cavity of the main body of the oil supply and return pump control box. An installation cavity is opened on the right surface of the insulating shell. Two elastic conductive plates are fixedly installed symmetrically in the upper and lower parts of the installation cavity. The elastic conductive plates are in a horizontal V shape. A wire is connected between the upper elastic conductive plate and the lighting lamp. A power line is connected to the lower elastic conductive plate. The end of the power line away from the elastic conductive plate passes through the main body of the oil supply and return pump control box and is connected to an external power source. A copper block is fixedly installed on the left side of the adapter block A. The copper block is inserted between the two elastic conductive plates.
[0009] In the above technical solution, an insulating plate is fixedly installed between the copper block and the adapter block A.
[0010] The advantages of this utility model's oil supply and return pump control box compared to the prior art are as follows:
[0011] When opening the cabinet door, the hinge block B and the hinge rod work together to pull the adapter block A to the left; when closing the cabinet door, the adapter block A can be pushed to the right. During wiring operations, cables connecting the electrical components on the cabinet door to those inside the control box can be secured in the cable tray of the elastic clip. During door closing, the cables move to the right with the adapter block A, moving them away from the gap between the cabinet door and the control box, thus preventing cable pinching and ensuring the cable's lifespan.

[0019] 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.
[0020] In this embodiment, front, back, left, right, top, and bottom are... Figure 1 Describe the reference plane. See [link / reference] Figures 1-6This utility model provides a technical solution:
[0021] A supply and return oil pump control box includes a supply and return oil pump control box body 1 and a box door 2. The box door 2 is rotatably installed in front of the supply and return oil pump control box body 1. A slider 31 is slidably installed on the lower surface of the inner cavity of the supply and return oil pump control box body 1. A transition block A4 is fixedly installed on the upper surface of the slider 31. A transition block B5 is fixedly installed on the side of the box door 2 used for installing electrical components. A hinge rod 6 is rotatably installed between the transition block B5 and the transition block A4. A vertical rod 41 is fixedly installed on the upper surface of the transition block A4. Multiple elastic clips 42 are snapped onto the outer surface of the vertical rod 41. Each elastic clip 42 has a wire harness slot 421 on its right surface. A lighting lamp 8 that can be automatically turned on when the box door 2 is opened is fixedly installed on the upper surface of the inner cavity of the supply and return oil pump control box body 1.
[0022] Before use, the cables connecting the electrical components on the door 2 to the electrical components inside the main body 1 of the oil supply and return pump control box are inserted into the cable tray 421 of the elastic clip 42 for storage. This way, when closing the door 2 after maintenance and repair, the adapter block A4 can be pushed to the right by the cooperation of the adapter block B5 and the hinge rod 6. The vertical rod 41 and the elastic clip 42 will then move the cables away from the gap between the door 2 and the main body 1 of the oil supply and return pump control box, thereby avoiding cable clamping and ensuring the normal service life of the cables.
[0023] Specifically, two L-shaped limiting plates 3 are fixedly installed on the lower surface of the inner cavity of the main body 1 of the oil supply and return pump control box. The two L-shaped limiting plates 3 are assembled with the lower surface of the inner cavity of the main body 1 of the oil supply and return pump control box to form a sliding groove. The slider 31 is slidably installed in the sliding groove. The slider 31 is installed on the lower surface of the inner cavity of the main body 1 of the oil supply and return pump control box by sliding left and right through the two L-shaped limiting plates 3.
[0024] Specifically, both adapter block A4 and adapter block B5 are provided with adapter grooves, and both ends of the hinge rod 6 are fixedly installed with hinge plates 61. The two hinge plates 61 are located in the corresponding adapter grooves, and hinge shafts 7 are installed between adapter block A4 and adapter block B5 and the corresponding hinge plates 61. By rotatably connecting the hinge plates 61 on both sides to adapter block A4 and adapter block B5 respectively using hinge shafts 7, the hinge rod 6 can be rotatably installed between adapter block A4 and adapter block B5.
[0025] It should be noted that, as Figure 2 , Figure 5 and Figure 6As shown, an insulating shell 9 is fixedly installed on the left side of the inner cavity of the main body 1 of the oil supply and return pump control box. An installation cavity 91 is opened on the right surface of the insulating shell 9. Two elastic conductive plates 92 are fixedly installed symmetrically in the upper and lower parts of the installation cavity 91. The elastic conductive plates 92 are in a horizontal V shape. A wire 81 is connected between the upper elastic conductive plate 92 and the lighting lamp 8. A power line 921 is connected to the lower elastic conductive plate 92. The end of the power line 921 away from the elastic conductive plate 92 passes through the main body 1 of the oil supply and return pump control box and is connected to an external power source. A copper block 44 is fixedly installed on the left side of the adapter block A4. The copper block 44 is inserted between the two elastic conductive plates 92.
[0026] When the door 2 is opened, the slider 31 slides to the far left. During the sliding process, the copper block 44 is inserted between the two elastic conductive plates 92, connecting the power supply to the lighting lamp 8. This allows the lighting lamp 8 to automatically turn on after the door 2 is opened, facilitating maintenance in dim lighting conditions. When the door 2 is closed, the slider 31 slides to the right, causing the copper block 44 to disengage from the elastic conductive plates 92, thereby cutting off the power supply to the lighting lamp 8 and automatically turning off the lighting lamp 8.
[0027] Finally, when the power supply to the lighting lamp 8 is turned on, in order to prevent current leakage and ensure that the current does not flow to the adapter block A4, an insulating plate 43 is fixedly installed between the copper block 44 and the adapter block A4. The insulating plate 43 can effectively prevent current leakage.
