[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0031] Example: Figure 1-4 As shown, this utility model provides a technical solution: an indoor low-voltage incoming line cabinet that is easy to maintain, including a cabinet body 1, a protective door 2 installed at one end of the cabinet body 1, an installation back plate 3 fitted to the inner wall of the cabinet body 1, components 4 installed at equal intervals in the middle of the installation back plate 3, and a convenient relocation and maintenance mechanism 5 provided inside the cabinet body 1.
[0032] The convenient relocation and maintenance mechanism 5 includes a support frame 501, a positioning screw hole 502, a moving plate 503, a positioning pin 504, a splicing cylinder 505, a winding rod 506, a splicing stud 507, and a limiting block 508.
[0033] A support frame 501 is installed at the bottom inside the cabinet 1. The top two ends of the support frame 501 are symmetrically provided with positioning screw holes 502. A movable plate 503 is installed on the top of the support frame 501. Positioning pins 504 are symmetrically installed at both ends of the movable plate 503. The bottom end of the mounting back plate 3 is fixedly connected to the top end of the movable plate 503. The bottom of the positioning pin 504 is movably embedded in the interior of the positioning screw hole 502. The edge of the movable plate 503 is in contact with the inner wall of the cabinet 1.
[0034] A splicing cylinder 505 is installed on the top of one side wall of the inner wall of cabinet 1. A winding rod 506 is installed at one end of the splicing cylinder 505, and a splicing stud 507 is connected to one end of the winding rod 506. Limiting blocks 508 are installed at equal intervals on the surface of the winding rod 506. The splicing stud 507 is movably embedded inside the splicing cylinder 505. The splicing stud 507 and the splicing cylinder 505 are connected by threads. The horizontal plane of the winding rod 506 is higher than the horizontal plane of the top of the mounting back plate 3. The support frame 501 and the movable plate 503 cooperate to provide a certain support for the mounting back plate 3 and components 4. The flexible mobility allows the component 4 to be pushed outwards during maintenance, greatly facilitating operation and maintenance. The positioning pin 504 can lock and fix the support frame 501 and the moving plate 503, improving its installation stability. At the same time, the splicing cylinder 505 and the splicing stud 507 work together to position the winding rod 506 above the component 4, guiding and limiting the connected lines, and allowing for the extension of the lines. This provides sufficient extension space for the movement and maintenance of the component 4, preventing the line length from limiting its movement.
[0035] The bottom of cabinet 1 is equipped with a movable adjustment mechanism 6;
[0036] The movable adjustment mechanism 6 includes an adjustment screw 601, a receiving groove 602, a rotating block 603, a moving wheel 604, a rotating block 605, a sealing rubber pad 606, a protective cover plate 607, and an operating protrusion 608.
[0037] Adjusting screws 601 are installed through the four corners of the bottom of the cabinet 1. Storage slots 602 are opened at the four corners of the bottom of the cabinet 1. The bottom of the adjusting screws 601 is connected to a rotating block 603. The positions of the four adjusting screws 601 correspond to the positions of the four storage slots 602. The rotating block 603 is located inside the storage slot 602. The adjusting screws 601 are connected to the cabinet 1 by threads. The bottom of the rotating block 603 is equipped with a moving wheel 604. The top of the adjusting screws 601 is equipped with a rotating block 605.
[0038] A sealing rubber pad 606 is fixedly bonded to the bottom edge of the cabinet 1. A protective cover 607 is movably installed at the bottom inside the cabinet 1. An operating protrusion 608 is connected to the bottom of the protective cover 607. Both sides of the cabinet 1 have slots. Both sides of the protective cover 607 are movably engaged in the slots. The use of casters 604 improves the mobility of the bottom of the cabinet 1, making it easy to move and transport the incoming line cabinet. At the same time, the cooperation of the adjusting screw 601 and the rotating block 605 makes it easy to adjust the height of the casters 604. When the incoming line cabinet is positioned and installed, the casters 604 can be hidden inside the storage groove 602, preventing the bottom of the incoming line cabinet from being separated from the ground, which would cause dust to accumulate and be difficult to clean.
[0039] The sealing rubber gasket 606 improves the fit and sealing between the cabinet 1 and the installation ground, preventing dust from entering. The sealing rubber gasket 606 also provides a certain buffer protection when the cabinet 1 is placed, preventing collision and friction between the cabinet 1 and the ground from causing damage to the ground. At the same time, the protective cover plate 607 is used to cover and protect the adjusting screw 601 from being directly exposed, making the interior of the cabinet 1 more aesthetically pleasing.
[0040] The working principle and usage process of this utility model are as follows: First, before moving and transporting the cabinet 1, the adjusting screw 601 is rotated using the rotating block 605, causing the height of the moving wheel 604 to decrease. The horizontal plane of the bottom of the moving wheel 604 is lower than the horizontal plane of the sealing rubber pad 606. Then, the staff can use the moving wheel 604 to push and move the cabinet 1 to the predetermined indoor installation position. The staff rotates the adjusting screw 601 to move the moving wheel 604 upward until the moving wheel 604 is stored and hidden inside the storage groove 602. Then, the sealing rubber pad 606 contacts the installation ground, so that there is no gap between the cabinet 1 and the installation ground, preventing dust accumulation. Then, the protective cover 607 is taken out and inserted into the cabinet 1 to cover the top of the adjusting screw 601.
[0041] Next, the staff installed and connected the internal components of cabinet 1. They took the winding rod 506, aligned the splicing stud 507 with the splicing cylinder 505, and screwed it into the cylinder 505 to secure the winding rod 506. Component 4 was then fixed to the mounting backplate 3. When connecting component 4 to the wiring, the wiring was routed around the surface of the winding rod 506 before connecting to component 4, ensuring a certain length of wiring remained inside cabinet 1. This pushed the mounting backplate 3 along with the moving plate 503 against the support frame 501. The top slides, allowing the mounting back plate 3 to fit tightly against the inner wall of the cabinet 1. The positioning pin 504 is aligned with the positioning screw hole 502 to lock and fix the moving plate 503. If maintenance is required later, the protective door 2 is opened, the positioning pin 504 is removed, and the moving plate 503 is pulled outward, causing the mounting back plate 3 and component 4 to move outward. Component 4 is closer to the outside, making it easier for staff to inspect and maintain it. In addition, the winding rod 506 has extra wires wound on it, allowing component 4 to move forward smoothly without being limited by the length of the wires.
[0042] 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.
