DETAILED DESCRIPTION
[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0025] like Figures 1 to 6As shown, a distribution box which is easy to maintain comprises a box body 1, a mounting plate 2 is slidably connected inside the box body 1, two symmetrically arranged guide rails 3 are fixedly connected to the top surface of the inner wall of the box body 1, a guide groove 4 is provided in the guide rail 3, two symmetrically arranged connecting blocks 5 are fixedly connected to the top of the mounting plate 2, a connecting rod 6 is fixedly connected to one side of the connecting block 5, a roller 7 is rotatably connected to the outer wall of one end of the connecting rod 6, the roller 7 is slidably connected to the guide groove 4, two fixed blocks 8 are fixedly connected to the top surface of the inner wall of the box body 1, threaded rods 9 are rotatably connected to the lower parts of the two fixed blocks 8, the threaded rods 9 are vertically arranged to the mounting plate 2, a moving block 10 is fixedly connected to the middle part of the top surface of the mounting plate 2, a threaded groove 11 corresponding to the position of the threaded rod 9 is provided in the moving block 10.
[0026] like Figure 1 As shown, a conveniently maintained distribution box in the utility model is similar to the existing distribution box structure, such as an intelligent remote control distribution box disclosed in the patent with announcement number CN220652703U. The main improvement of the utility model is to make the distribution box easy to maintain, such as Figures 1 to 6 As shown, when a distribution box that is easy to maintain in the utility model is in use, the staff installs the electronic components in the distribution box on the mounting plate 2 during installation; when the electronic components and wires need to be maintained, the staff rotates the threaded rod 9, and the rotation of the threaded rod 9 will drive the moving block 10 to move along the threaded rod 9, and then drive the mounting plate 2 to move to the front side of the box body 1, and the staff can perform maintenance work on the electronic components and wires on the mounting plate 2; the guide rail 3 and the roller 7 can improve the stability of the mounting plate 2 during movement, and ensure that the mounting plate 2 will not be skewed left and right; the matching design between the threaded rod 9 and the moving block 10 enables the mounting plate 2 to be firmly fixed after being moved into place, avoiding movement due to accidental touch during maintenance, thereby ensuring the safety and reliability of maintenance operations.
[0027] By arranging the threaded rod 9, the mounting plate 2 and the guide rail 3 in the box body 1, when the internal electronic components and wires need to be inspected, replaced or repaired, the staff does not need to go deep into the complex box body 1. They only need to screw the threaded rod 9 from the outside to easily drive the mounting plate 2 to slide along the guide rail 3 to the front end of the box body 1. At this time, the electronic components and wires will be completely exposed, which is convenient for direct operation and maintenance, and brings convenience to the maintenance work of the staff.
[0028] like Figure 5 As shown, the cross-section of the guide rail 3 is U-shaped, and the two sides of the U are of different lengths. The long side of the guide rail 3 is fixedly connected to the top surface of the inner wall of the box body 1, the connecting rod 6 is located between the short side of the guide rail 3 and the top surface of the inner wall of the box body 1, and the roller 7 is located between the long side and the short side of the guide rail 3.
[0029] Specifically, the guide rail 3 adopts a U-shaped design, and its longer side is fixed against the top surface of the inner wall of the box body 1, while the roller 7 is located inside the opening of the U-shaped guide rail 3 and rolls along the long side, so that the roller 7 is always constrained by the guide rail 3 and will not deviate from the track. The connecting rod 6 is located between the shorter side of the guide rail 3 and the top surface of the box body 1, and the roller 7 is located between the connecting rod 6 and the short side of the guide rail 3. The geometric constraint relationship formed in this way ensures that when the mounting plate 2 moves, the rollers 7 on both sides will roll along the guide rail 3 synchronously and evenly, so that the mounting plate 2 remains horizontal and stable during the forward and backward movement, avoiding tilting or swaying due to uneven force; the U-shaped guide rail 3 can also prevent the roller 7 from accidentally leaving the track through its own structure, thereby enhancing the reliability of the overall structure. Through such a setting, when the staff operates the threaded rod 9 to move the mounting plate 2, it can ensure that the mounting plate 2 and the electronic components thereon always remain on a predetermined stable track, greatly improving the safety and convenience of maintenance operations.
[0030] like Figure 3 and Figure 4 As shown, two symmetrically arranged connecting grooves 12 are provided at the bottom of the mounting plate 2, a rotating shaft 13 is fixedly connected inside the connecting groove 12, a pulley 14 is rotatably connected to the outer wall of the rotating shaft 13, two slide rails 15 are fixedly connected to the bottom surface of the inner wall of the box body 1, and a sliding groove 16 corresponding to the position of the pulley 14 is provided on the surface of the slide rail 15.
[0031] Specifically, the cooperation between the slide rail 15 and the pulley 14 provides a certain support effect for the mounting plate 2, reduces the pressure on the guide rail 3, provides guidance for the lower part of the mounting plate 2, prevents the lower part of the mounting plate 2 from bending or tilting, and further improves the stability of the mounting plate 2 during movement.
[0032] like Figure 3 and Figure 4 As shown, a clamping groove 17 is formed at one end of the threaded rod 9, a clamping rod 18 is slidably connected in the clamping groove 17, and a rotating plate 19 is fixedly connected to one end of the clamping rod 18.
[0033] Specifically, the cross section of the clamping rod 18 is a hexagonal or cross-shaped graphic setting that is convenient for stable clamping. By using the rotating plate 19 and the clamping rod 18, the staff can rotate the threaded rod 9 by rotating the rotating plate 19, thereby adjusting the position of the mounting plate 2. The matching design of the clamping groove 17 and the clamping rod 18 allows the staff to operate without directly contacting the threaded rod 9, avoiding the risk of slipping or spraining caused by hand sliding, while also providing greater torque, making the rotation more labor-saving and precise.
[0034] like Figure 4As shown, a positioning block 20 is fixedly connected to the bottom surface of the inner wall of the box body 1, and a positioning groove 21 corresponding to the position of the clamping rod 18 is opened on the surface of the positioning block 20. A limiting block 22 is fixedly connected to the bottom surface of the inner wall of the box body 1, and both sides of the mounting plate 2 are respectively in contact with the rotating plate 19 and the limiting block 22. The bottom end of the mounting plate 2 is higher than the height of the positioning block 20 to ensure that the mounting plate 2 slides smoothly and can be limited by the rotating plate 19 between the rotating plate 19 and the limiting block 22.
[0035] Specifically, when the mounting plate 2 is in normal use, the bottom of the mounting plate 2 will be located between the rotating plate 19 and the limit block 22. The rotating plate 19 and the limit block 22 will provide fixation for the bottom of the mounting plate 2, effectively preventing the mounting plate 2 from accidentally moving or shaking due to external forces and other factors in a non-maintenance state, thereby ensuring the stable installation and working state of the electrical components on the mounting plate 2; at the same time, the positioning groove 21 also realizes the storage of the clamping rod 18 and the rotating plate 19, preventing the clamping rod 18 and the rotating plate 19 from being lost, realizing multiple uses of one item, and improving the practicality of the clamping rod 18 and the rotating plate 19.
[0036] like Figure 3 and Figure 6 As shown, two fixing holes 23 are provided on both sides of the surface of the fixing block 8, and fasteners 24 are fixedly connected in the fixing holes 23.
[0037] Specifically, the fastener 24 is a matching bolt and nut arrangement. By using the fastener 24, the installation and disassembly between the fixing block 8 and the mounting plate 2 can be achieved, which brings convenience to the installation, disassembly and replacement of the mounting plate 2.
[0038] like Figure 4 As shown, a brake block 25 is fixedly connected to one end of the slide rail 15 .
[0039] Specifically, the brake block 25 can prevent the pulley 14 from continuing to slide forward due to inertia or other reasons when the mounting plate 2 moves to the extreme position, so as to disengage from the slide rail 15, thereby causing accidents such as the mounting plate 2 falling off, damage to electronic components or personal injury. This arrangement ensures the stability and safety of the mounting plate 2 during the sliding process, and by preventing the pulley 14 from continuing to move forward, the moving distance of the mounting plate 2 is effectively limited and positioned, ensuring that the mounting plate 2 is always within the safety range allowed by the design.
[0040] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
