Description

Technical Field

[0001] This application relates to the technical field of frame structures, and in particular to a frame structure for an electrical testing circuit control cabinet. Background Technology

[0002] The electrician assessment circuit control cabinet is a multi-functional training device specifically designed for training and assessing electrician skills. It is also a teaching and examination platform. Its core purpose is to simulate various circuits and control tasks in real industrial scenarios in a safe and controllable environment, allowing electricians to perform operations such as installation, wiring, debugging, and troubleshooting. Examiners will then assess their skills based on their operating procedures and results.

[0003] Existing control cabinet frame structures typically consist of a frame body and two perforated plates. The two perforated plates are bolted to the frame body, while the circuitry and equipment are installed between them. This structure is common in the industry; the bolted fixation ensures the stability of the connection between the perforated plates and the frame body, allowing the control cabinet to maintain structural integrity during use and ensuring the normal operation of the circuitry and equipment. However, to maintain the cleanliness of the perforated plates, they need to be cleaned regularly. Installing and removing the perforated plates requires tools to tighten or loosen each bolt, making the installation and removal process very slow and requiring improvement. Utility Model Content

[0004] The purpose of this application is to provide a frame structure for an electrical engineering assessment circuit control cabinet to improve the efficiency of installing or removing the perforated plate.

[0005] The electrical engineering assessment circuit control cabinet frame structure provided in this application adopts the following technical solution: it includes a frame body, the frame body is connected to a lighting lamp and an output panel, the bottom of the frame body is connected to several rollers, the frame body is detachably connected to two perforated plates, an installation cavity is formed between the two perforated plates, the frame body is connected to at least four fixing components, one perforated plate corresponds to at least two fixing components, the fixing component includes an installation block connected to the frame body and a fixing block slidably connected to the installation block, the perforated plate is provided with fixing grooves corresponding one-to-one with the fixing blocks, the fixing grooves are used to cooperate with the fixing blocks.

[0006] By adopting the above technical solution, when installing the perforated plate, one of the perforated plates is placed between two fixing components. The perforated plate covers the mounting cavity, and the fixing block corresponds to the fixing groove. Moving the fixing block towards the fixing groove causes one end of the fixing block to engage with the groove, and the outer surface of the fixing block fits against the inner wall of the groove. The fixing block restricts the perforated plate from detaching from the frame body, thus securing the perforated plate. When disassembling the perforated plate, moving the fixing block in the opposite direction disengages it from the fixing groove. The fixing block no longer restricts the movement of the perforated plate, allowing it to be removed from the frame body. This application avoids the use of bolts for fixing, improving the efficiency of perforated plate installation and disassembly.

[0007] Optionally, the fixing block is provided with two limiting parts, and the mounting block is provided with a sliding groove and two limiting grooves communicating with the sliding groove. The sliding groove is used to slide and cooperate with the fixing block, and the limiting groove is used to slide and cooperate with the limiting part. Both ends of the fixing block protrude from the sliding groove.

[0008] By adopting the above technical solution, when the fixed block slides, the limiting part and the limiting groove slide together, which plays a guiding and limiting role in the sliding of the fixed block, preventing the fixed block from falling out of the groove during the sliding process and improving the stability of the fixed block sliding.

[0009] Optionally, the fixing assembly further includes a cover plate detachably connected to the mounting block, the cover plate being used to cover the slide groove and the limiting groove.

[0010] By adopting the above technical solution, the cover plate covers the sliding groove and the limiting groove. The cover plate plays a limiting role in the sliding of the limiting part and the fixing block, preventing the limiting part from leaving the limiting groove during the sliding process, and also limiting the fixing block from leaving the sliding groove during the sliding process.

[0011] Optionally, the mounting block is connected to a positioning component, which is used to position the fixing block so that the fixing block is engaged or disengaged from the fixing groove.

[0012] By adopting the above technical solution, the positioning component can position the fixing block, so that the fixing block can be accurately engaged or disengaged from the fixing groove, which facilitates the quick installation or disassembly of the perforated plate and improves the efficiency of perforated plate installation and disassembly.

[0013] Optionally, the positioning component includes an elastic positioning part connected to the inner wall of each of the limiting grooves. Each limiting part is provided with two first positioning grooves at intervals. The two first positioning grooves are distributed along the moving direction of the fixed block. The first positioning grooves are used to cooperate with the elastic positioning part. When the elastic positioning part is engaged in one of the first positioning grooves, the fixed block is located in the fixed groove. When the elastic positioning part is engaged in the other first positioning groove, the fixed block is disengaged from the fixed groove.

[0014] By adopting the above technical solution, the elastic positioning part cooperates with the first positioning groove to position the fixed block, so that the fixed block can be accurately engaged or disengaged from the fixed groove. When the elastic positioning part is engaged from one of the first positioning grooves into the other, the elastic positioning part undergoes elastic deformation and remains elastically reset until the elastic positioning part corresponds to one of the first positioning grooves. At this point, the elastic positioning part elastically resets and fits against the inner wall of the first positioning groove, thereby achieving the positioning of the fixed block.

[0015] Optionally, the end of the elastic positioning part near the limiting part is arc-shaped.

[0016] By adopting the above technical solution, the arc-shaped elastic positioning part facilitates the switching of the elastic positioning part between the first positioning grooves, making the fixing block more smoothly inserted into or removed from the fixing groove, and further improving the convenience of installing and disassembling the perforated plate.

[0017] Optionally, the positioning component includes a ball slidably connected in the limiting groove and an elastic element connected to the ball. The mounting block is provided with a receiving groove communicating with the limiting groove. The ball slides in cooperation with the receiving groove. The end of the elastic element away from the ball is connected to the inner wall of the receiving groove. Each limiting part is provided with two second positioning grooves at intervals. The two second positioning grooves are distributed along the moving direction of the fixing block. The second positioning grooves are used to cooperate with the ball. When the ball is inserted into one of the second positioning grooves, the fixing block is located in the fixing groove. When the ball is inserted into the other second positioning groove, the fixing block is disengaged from the fixing groove.

[0018] By adopting the above technical solution, when the ball moves from one of the second positioning grooves to another, the limiting part abuts against the ball and drives the ball to be inserted into the receiving groove. The elastic element is compressed and undergoes elastic deformation and maintains the tendency of elastic reset until the ball corresponds to another second positioning groove. The elastic element then elastically resets, forcing the ball to reset. The ball is inserted into the second positioning groove and fits against the inner wall of the second positioning groove, thereby realizing the positioning of the fixed block.

[0019] Optionally, the fixing block has a groove at one end away from the perforated plate, the groove being located on the side of the fixing block away from the mounting block, and the groove protruding from the sliding groove.

[0020] By adopting the above technical solution, when the fixing block is pulled out of the fixing groove, the operator places his hand in the groove and applies force to the inner wall of the groove. The groove is designed to provide a support point for pulling the fixing block, thereby improving the efficiency of pulling the fixing block out of the groove.

[0021] Optionally, the frame body is connected to four mounting plates, one of the perforated plates corresponds to two of the mounting plates, the two mounting plates are spaced apart, and a mounting groove is opened on one side of the two mounting plates facing each other. The mounting groove passes through the top of the mounting plate and is used to cooperate with the perforated plate. The mounting plate is provided with clearance holes that correspond one-to-one with the fixing blocks. The clearance holes communicate with the mounting groove and are used for the fixing blocks to pass through.

[0022] By adopting the above technical solution, when installing the perforated plate, the perforated plate is inserted into the mounting groove, and the outer surface of the perforated plate fits against the inner wall of the mounting groove. The inner wall of the mounting groove plays a positioning role in the installation of the perforated plate, that is, the fixing block corresponds to the fixing groove, which improves the efficiency of fixing the perforated plate.

[0023] Optionally, the inner wall of each mounting slot is provided with a guide surface, which is used to abut against the perforated plate.

[0024] By adopting the above technical solution, when installing the perforated plate, the perforated plate abuts against the guide surface, and the guide surface plays a guiding role in the installation of the perforated plate, so that the perforated plate can be smoothly inserted into the installation groove, thereby improving the installation efficiency of the perforated plate.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. When installing the perforated plate, one of the perforated plates is placed between two fixing components, the perforated plate covers the mounting cavity and the fixing block corresponds to the fixing groove. The fixing block is moved towards the fixing groove, so that one end of the fixing block is inserted into the fixing groove, and the outer surface of the fixing block is in contact with the inner wall of the fixing groove. The fixing block restricts the perforated plate from detaching from the frame body, thereby fixing the perforated plate. When disassembling the perforated plate, the fixing block is moved in the opposite direction, the fixing block disengages from the fixing groove, and the fixing block no longer restricts the movement of the perforated plate, so the perforated plate can be removed from the frame body. This application avoids the use of bolts for fixing, improving the efficiency of perforated plate installation and disassembly.

[0026] 2. The positioning component can position the fixing block, allowing it to accurately engage or disengage from the fixing groove, facilitating quick installation or disassembly of the perforated plate and improving the efficiency of perforated plate installation and disassembly.

[0035] The following is in conjunction with the appendix Figure 1 - Appendix Figure 7 This application will be described in further detail.

[0036] This application discloses a frame structure for an electrical engineering assessment circuit control cabinet.

[0037] Example 1

[0038] Combination Figure 1 , Figure 2 and Figure 3As shown, the system includes a frame body 1. Four rollers 11 are fixedly connected to the bottom of the frame body 1, located at the four corners of the frame body 1. A lighting lamp 12 and an output panel 13 are fixedly connected to the top of the frame body 1. Two perforated plates 2 are detachably connected to the frame body 1, with a mounting cavity formed between the two perforated plates 2. At least four fixing components 3 are connected to the frame body 1. In this embodiment, for example, there are eight fixing components 3, with one perforated plate 2 corresponding to four fixing components 3. The frame body 1 is connected to four mounting plates 4. One perforated plate 2 corresponds to two mounting plates 4, which are spaced apart. A mounting groove 41 is formed on one side of each mounting plate 4, extending through the top of the mounting plate 4. The perforated plate 2 is inserted into the mounting groove 41 from above the mounting plate 4. A guide surface 42 is formed on the inner wall of the mounting groove 41, located at the top of the mounting plate 4. When installing the perforated plate 2, it abuts against the guide surface 42, which guides the installation of the perforated plate 2, allowing it to fit more smoothly into the mounting groove 41. Each mounting plate 4 has two clearance holes 43, spaced apart along the length of the mounting plate 4. These clearance holes 43 communicate with the mounting groove 41 and correspond one-to-one with the fixing component 3.

[0039] Combination Figure 4 , Figure 5 and Figure 6 As shown, the fixing component 3 includes a mounting block 31 fixedly connected to the frame body 1 and a fixing block 32 slidably connected to the mounting block 31. A groove 311 is provided on the side of the mounting block 31 away from the frame body 1. The fixing block 32 slides into the groove 311. The groove 311 penetrates the left and right side walls of the mounting block 31 and corresponds to the clearance hole 43. A fixing groove 21, corresponding to the fixing block 32, is provided on the side of the perforated plate 2. During sliding, the fixing block 32 passes through the clearance hole 43 and fits against the inner wall of the fixing groove 21. A pull groove 321 is provided at the end of the fixing block 32 away from the perforated plate 2. The pull groove 321 penetrates the upper and lower side walls of the fixing block 32 and is located on the side of the fixing block 32 away from the mounting block 31. The pull groove 321 always protrudes from the groove 311, facilitating the operator to pull the fixing block 32 through the pull groove 321.

[0040] Combination Figure 4 , Figure 5 and Figure 6As shown, the fixing block 32 has two limiting parts 322 arranged opposite to each other. The limiting parts 322 are integrally formed with the fixing block 32. The mounting block 31 has limiting grooves 312 that correspond one-to-one with the limiting parts 322. The limiting grooves 312 communicate with the sliding grooves 311. The limiting parts 322 are engaged with the limiting grooves 312 and slide in cooperation with the limiting grooves 312. The fixing assembly 3 also includes a cover plate 33 that is detachably connected to the mounting block 31. The cover plate 33 is fixedly connected to the mounting block 31 by a number of screws. When the cover plate 33 is installed on the mounting block 31, the cover plate 33 covers the sliding grooves 311 and the limiting grooves 312. The mounting block 31 is connected to a positioning component 5, which positions the fixing block 32 so that the fixing block 32 can be engaged or disengaged from the fixing groove 21. The positioning component 5 includes an elastic positioning part 51 fixedly connected to the inner wall of each limiting groove 312. The end of the elastic positioning part 51 near the limiting part 322 is arc-shaped. Each limiting part 322 has two first positioning grooves 323 spaced apart. The first positioning grooves 323 are distributed along the moving direction of the fixing block 32. The elastic positioning part 51 engages with the first positioning groove 323 and fits against the inner wall of the first positioning groove 323. When the elastic positioning part 51 engages with one of the first positioning grooves 323, the fixing block 32 is located in the fixing groove 21. When the elastic positioning part 51 engages with the other first positioning groove 323, the fixing block 32 disengages from the fixing groove 21.

[0041] The implementation principle of the electrical engineering assessment circuit control cabinet frame structure in this application embodiment is as follows: When installing the perforated plate 2, one of the perforated plates 2 is placed between two fixing components 3. The perforated plate 2 covers the mounting cavity, and the fixing block 32 corresponds to the fixing groove 21. The fixing block 32 is moved towards the fixing groove 21, so that one end of the fixing block 32 is inserted into the fixing groove 21, and the outer surface of the fixing block 32 is in contact with the inner wall of the fixing groove 21. The fixing block 32 restricts the perforated plate 2 from detaching from the frame body 1, thereby fixing the perforated plate 2. When disassembling the perforated plate 2, the fixing block 32 is moved in the opposite direction, and the fixing block 32 is disengaged from the fixing groove 21. The fixing block 32 no longer restricts the movement of the perforated plate 2, and the perforated plate 2 can be removed from the frame body 1. This application avoids the use of bolts for fixing, improving the efficiency of installing and disassembling the perforated plate 2.

[0042] Example 2

[0043] The difference between this embodiment and Embodiment 1 is that, as Figure 7As shown, the positioning component 5 includes a ball 52 slidably connected in the limiting groove 312 and an elastic element 53 fixedly connected to the ball 52. The elastic element 53 is a spring. The mounting block 31 has a receiving groove 313 communicating with the limiting groove 312. The ball 52 slides in cooperation with the receiving groove 313. The end of the elastic element 53 away from the ball 52 is fixedly connected to the inner wall of the receiving groove 313. Each limiting part 322 has two second positioning grooves 324 spaced apart. The two second positioning grooves 324 are distributed along the moving direction of the fixing block 32. The ball 52 is inserted into the second positioning groove 324 and fits against the inner wall of the second positioning groove 324. When the ball 52 is inserted into one of the second positioning grooves 324, the fixing block 32 is located in the fixing groove 21. When the ball 52 is inserted into the other second positioning groove 324, the fixing block 32 is disengaged from the fixing groove 21.
