Description

Technical Field

[0001] This utility model belongs to the field of power distribution cabinet technology, and more specifically, it relates to a drawer-type power distribution cabinet. Background Technology

[0002] Distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), and are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits; motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy from a circuit of the upstream power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.

[0003] Based on the above, the inventors have discovered the following problems: Most drawer-type power distribution cabinets currently have a handle switch on one side of the drawer to lock the drawer. However, the structure of the handle switch is relatively complex, and if the handle switch is damaged, the drawer will be difficult to pull out, which causes inconvenience to the staff.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a drawer-type power distribution cabinet in order to achieve a more practical value. Utility Model Content

[0005] The purpose and function of this utility model's drawer-type power distribution cabinet are achieved through the following specific technical means:

[0006] A drawer-type distribution cabinet includes a cabinet body with several drawers installed inside. One end of each drawer extends through the cabinet body to the outside and is connected to a handle. Slider blocks are installed on both sides of each drawer. Several sliding grooves are formed inside the cabinet body, and the sliders are slidably installed inside the sliding grooves. A limiting component is provided on one side of each sliding groove. The limiting component includes several sliding slots formed on one side of the cabinet body. A sliding rod is installed inside each sliding groove, and a connecting block is fitted onto the sliding rod. A spring is fitted around the sliding rod, with one end of the spring connected to the top of the sliding groove and the other end of the spring connected to the top of the connecting block. A baffle is installed on one side of the connecting block. A mounting groove is formed on one side of the slider, and several rollers are mounted inside the mounting groove via a rotating shaft.

[0007] Furthermore, a limiting plate is installed on one side of the baffle, and a through hole is formed on the surface of the limiting plate, with a positioning hole connected to one side of the through hole.

[0008] Furthermore, a number of fixing blocks are installed on one side of the cabinet, and a rotating block is provided on the top of the fixing block. A rotating rod is installed at one end of the rotating block, and one end of the rotating rod extends through the fixing block to the bottom. The position of the rotating rod corresponds to the through hole. A positioning block is installed on one side of the rotating rod, and the positioning block matches the positioning hole.

[0009] Furthermore, several heat dissipation holes are provided on both sides of the cabinet, and a mounting frame is provided on one side of each heat dissipation hole, with a filter screen installed inside the mounting frame.

[0010] Furthermore, the surfaces of the cabinet and the mounting frame are provided with several threaded holes, and bolts are installed inside the threaded holes.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. Through the coordinated use of springs, baffles, limit plates, and positioning blocks, when a drawer needs to be pulled out, the baffle is lifted upwards. The baffle moves the connecting block and compresses the spring. After the rotating rod and positioning block pass through the through hole and positioning hole, the rotating block is rotated. Then, the positioning block supports the limit plate. At this time, the baffle is fixed and the slide groove is exposed. Then, the operator can pull out the drawer through the handle. When the drawer needs to be locked, the drawer is pushed into the cabinet. Then, the rotating block is rotated in the opposite direction. When the positioning block overlaps with the positioning hole, the spring rebounds and quickly pushes the baffle downwards, blocking the slide groove. Thus, the drawer is fixed inside the cabinet. The overall structure is simple, the operation is convenient and quick, and it brings convenience to the operator.

[0013] 2. The roller design reduces the impact of friction on drawer movement, making it easier to quickly pull out the drawer.

[0014] 3. Through the combined use of the filter screen, threaded holes, and bolts, the filter screen can intercept dust on the outside, preventing dust from entering the cabinet through the heat dissipation holes and affecting the use of electrical components. When the filter screen needs to be cleaned or replaced, the bolts are loosened to disengage from the threaded holes, thereby separating the mounting frame from the cabinet. Then, the staff can clean or replace the filter screen, preventing it from being clogged by a large amount of dust and thus affecting the heat dissipation efficiency. Attached Figure Description

[0025] As attached Figure 1 To be continued Figure 4 As shown:

[0026] This utility model provides a drawer-type power distribution cabinet, including a cabinet body 1. Several drawers 2 are installed inside the cabinet body 1. One end of each drawer 2 passes through the cabinet body 1 and is connected to a handle 3 on the outside. Slider blocks 21 are installed on both sides of each drawer 2. Several sliding grooves 13 are formed inside the cabinet body 1. The sliders 21 are slidably installed inside the sliding grooves 13. A limiting component is provided on one side of each sliding groove 13. The limiting component includes several sliding slots 8 formed on one side of the cabinet body 1. A sliding rod 9 is installed inside each sliding groove 8. A connecting block 11 is fitted onto the sliding rod 9. A spring 10 is fitted around the sliding rod 9. One end of the spring 10 is connected to the top of the sliding groove 8, and the other end of the spring 10 is connected to the top of the connecting block 11. A baffle 12 is installed on one side of the connecting block 11. A mounting groove is formed on one side of each slider 21. Several rollers 22 are mounted inside the mounting groove via a rotating shaft. The spring 10, baffle 12, limiting plate 14, and positioning block 20 work together. When drawer 2 needs to be pulled out, baffle 12 is lifted upwards. Baffle 12 drives connecting block 11 to move and compress spring 10. After rotating rod 19 and positioning block 20 pass through through hole 15 and positioning hole 16, rotating block 18 is rotated. Then positioning block 20 supports limiting plate 14. At this time, baffle 12 is fixed and slide groove 13 is exposed. Then the operator can pull out drawer 2 through handle 3. When drawer 2 needs to be locked, drawer 2 is pushed into cabinet 1. Then rotating block 18 is rotated in the opposite direction. When positioning block 20 overlaps with positioning hole 16, spring 10 rebounds and quickly pushes baffle 12 downwards and blocks slide groove 13. Thus, drawer 2 is fixed inside cabinet 1. The overall structure is simple and the operation is convenient and quick, which brings convenience to the operator. In addition, roller 22 reduces the impact of friction on the movement of drawer 2, making it easy to pull out drawer 2 quickly.

[0027] A limiting plate 14 is installed on one side of the baffle 12. A through hole 15 is provided on the surface of the limiting plate 14, and a positioning hole 16 is connected to one side of the through hole 15.

[0028] Among them, a number of fixing blocks 17 are installed on one side of the cabinet 1, and a rotating block 18 is provided on the top of the fixing block 17. A rotating rod 19 is installed on one end of the rotating block 18. One end of the rotating rod 19 extends through the fixing block 17 to the bottom. The position of the rotating rod 19 corresponds to that of the through hole 15. A positioning block 20 is installed on one side of the rotating rod 19. The positioning block 20 matches the positioning hole 16.

[0029] The cabinet 1 has several heat dissipation holes 4 on both sides, and a mounting frame 5 is provided on one side of the heat dissipation hole 4. A filter screen 6 is installed inside the mounting frame 5. Through the design of the filter screen 6, the filter screen 6 can intercept dust on the outside, preventing dust from entering the cabinet 1 through the heat dissipation hole 4 and thus affecting the use of electrical components.

[0030] The cabinet body 1 and the mounting frame 5 are provided with several threaded holes 23 on their surfaces. Bolts 7 are installed inside the threaded holes 23. When the filter screen 6 needs to be cleaned or replaced, the bolts 7 are turned to disengage from the threaded holes 23, thereby separating the mounting frame 5 from the cabinet body 1. Then, the staff can clean and replace the filter screen 6, avoiding the problem of the filter screen 6 being blocked by a large amount of dust, which would affect the heat dissipation efficiency.

[0031] The specific usage and function of this embodiment are as follows:

[0032] First, check the integrity of the device. Use it only after confirming it is correct. When drawer 2 needs to be pulled out, lift the baffle 12 upwards. The baffle 12 moves the connecting block 11 and compresses the spring 10. After the rotating rod 19 and the positioning block 20 pass through the through hole 15 and the positioning hole 16, rotate the rotating block 18. Then, the positioning block 20 supports the limiting plate 14. At this time, the baffle 12 is fixed and the slide groove 13 is exposed. Then, the operator can pull out drawer 2 through the handle 3. The design of the roller 22 reduces the impact of friction on the movement of drawer 2, making it easy to quickly pull out drawer 2. When drawer 2 needs to be locked, push drawer 2 into the cabinet 1, and then rotate the rotating block 18 in the opposite direction. When the position of the 20 overlaps with the positioning hole 16, the spring 10 rebounds and quickly pushes the baffle 12 downward and blocks the slide 13, thus fixing the drawer 2 inside the cabinet 1. The overall structure is simple and the operation is convenient and quick, bringing convenience to the staff. At the same time, the filter screen 6 intercepts dust outside, preventing dust from entering the cabinet 1 through the heat dissipation hole 4 and affecting the use of electrical components. When the filter screen 6 needs to be cleaned or replaced, the bolt 7 is turned so that the bolt 7 is disengaged from the threaded hole 23, thereby separating the mounting frame 5 from the cabinet 1. Then the staff can clean and replace the filter screen 6, avoiding the problem of the filter screen 6 being blocked by a large amount of dust, which would affect the heat dissipation efficiency.
