Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1 to 6 This utility model provides a technical solution:

[0026] Example 1: A power distribution cabinet that facilitates wiring and maintenance, comprising: cabinet body 1.

[0027] Specifically, cable guide holes 11 are provided on both sides of the bottom of the cabinet 1. These holes are used to pass through the input and output cables of the cabinet 1. The bottom of the cabinet 1 is also equipped with support legs to prevent direct contact between the bottom of the cabinet 1 and the ground, thus preventing rainwater from seeping into the interior of the cabinet 1. A support ring 6 corresponding to the cable guide holes 11 is located at the bottom of the interior of the cabinet 1. The support ring 6 is rotatable. A mounting plate 2 is located on the upper side of the support ring 6, and the lower end of the mounting plate 2 is fastened and fixed to the support ring 6. The mounting plate 2 and the support ring 6 rotate synchronously. By controlling the forward and reverse rotation of the mounting plate 2, [the system can be configured to rotate]. The mounting plate 2 is positioned so that its front and back faces the opening on the front of the cabinet 1, facilitating the installation of electrical components and subsequent maintenance. A mounting base 3 is fixedly installed on the top of the cabinet 1, and a positioning clamp 5 is rotatably connected to the mounting base 3 below it. The positioning clamp 5 has a downward-opening "U"-shaped cross-section. The upper end of the mounting plate 2 is movably inserted into the inner cavity of the positioning clamp 5, and the two are fixedly connected by bolts. The positioning clamp 5 can only rotate. By fixing the mounting plate 2 to the positioning clamp 5, the mounting plate 2 is positioned, ensuring that it can only rotate within the inner cavity of the cabinet 1. Figure 1 As shown, the mounting plate 2 is located at the diameter of the wire hole 11. The mounting plate 2 divides the inner cavity of the wire hole 11 into two. The input and output cables of the cabinet 1 can extend into the inner cavity of the cabinet 1 from both sides of the mounting plate 2, and the cables can be laid upward along the surface of the mounting plate 2. The cables are parallel to and nearly coincident with the rotation axis of the mounting plate 2. Therefore, when the mounting plate 2 rotates, the movement of the cables is minimal, thereby avoiding the loosening of cable joints and the breaking of cables. In addition, in actual use, the mounting plate 2 only needs to be rotated 90 degrees forward or backward. The rotation angle of the mounting plate 2 itself is small and within the range of the torsion angle that the cables can withstand. Therefore, there is no need to worry about the cables being broken due to excessive torsion angle.

[0028] The mounting plate 2 has a relief groove 22 at the lower center, and the relief groove 22 is located directly above the support ring 6. The lower surface of the support ring 6 is fixed with an annular baffle 61, which is movably embedded in the inner cavity of the wire hole 11 and rotatably connected to it.

[0029] To prevent the mounting plate 2 from separating from the support ring 6, this application also includes a rolling element 63 movably embedded at the lower surface edge of the support ring 6. The rolling element 63 is used to reduce the friction between the support ring 6 and the bottom of the cabinet 1 when the support ring 6 rotates. A groove 62 is formed on the upper surface of the support ring 6 along its own diameter direction. The lower end of the mounting plate 2 is inserted into the inner cavity of the groove 62. The groove 62 is used to prevent the mounting plate 2 from moving in a direction perpendicular to its own surface, which would cause the mounting plate 2 to separate from the support ring 6.

[0030] To prevent the mounting plate 2 from shifting position, this application also provides a snap-fit ​​groove 23 at the lower center of the mounting plate 2. The snap-fit ​​groove 23 is snapped onto the outside of the support ring 6. The snap-fit ​​groove 23 can prevent the mounting plate 2 from moving horizontally along its width direction, which would cause the mounting plate 2 to detach from the support ring 6. The snap-fit ​​groove 23 and the groove 62 mentioned above cooperate with each other to achieve relative fixation between the mounting plate 2 and the support ring 6 in the horizontal direction, thereby preventing them from separating. Positioning holes 21 and mating holes 51 are respectively provided on the upper side of the mounting plate 2 and the side of the positioning clamp 5, and the two are directly opposite each other. After the positioning clamp 5 and the mounting plate 2 are fixedly connected by bolts, the relative fixation between the positioning clamp 5, the mounting plate 2 and the support ring 6 can be achieved, ensuring that the mounting plate 2 can only rotate within the cavity of the cabinet 1.

[0031] To facilitate the disassembly and replacement of the mounting plate 2, this application also provides a gap between the upper end face of the mounting plate 2 and the bottom of the groove of the positioning clamp 5, and the vertical width of the gap is greater than the vertical width of the snap-fit ​​groove 23. When the mounting plate 2 needs to be disassembled and replaced, first loosen the bolts between the positioning clamp 5 and the mounting plate 2, and then pull the mounting plate 2 upward until the snap-fit ​​groove 23 and the groove 62 separate from each other. At this time, by sliding the mounting plate 2 along the width direction of the mounting plate 2, the mounting plate 2 can be removed from between the mounting base 3 and the support ring 6, thereby realizing the disassembly of the mounting plate 2.

[0032] To install and connect the positioning clamp 5, the mounting base 3 of this application is fixedly connected to the top of the cabinet 1 by bolts. A rotating platform 4 is rotatably mounted inside the mounting base 3. The rotating platform 4 is stepped, and its lower end extends to the bottom of the mounting base 3. The positioning clamp 5 is fixed to the lower end face of the rotating platform 4. Figure 5 As shown, the rotary table 4 can only rotate, and the positioning clamp 5 can achieve a rotational connection with the mounting base 3 by being fixedly connected to the rotary table 4.

[0033] To prevent the connection structure between the positioning clamp 5 and the rotating table 4 from affecting the upward movement of the mounting plate 2, this application also has at least two countersunk holes 53 opened in the bottom of the groove of the positioning clamp 5. The positioning clamp 5 and the rotating table 4 are fixedly connected by hexagon socket head cap screws 52 passing through the inner cavity of the countersunk holes 53. The lower end face of the hexagon socket head cap screws 52 is flush with the bottom of the groove of the positioning clamp 5. The countersunk holes 53 and the hexagon socket head cap screws 52 are provided to fix the positioning clamp 5 and the rotating table 4. The lower end of the hexagon socket head cap screws 52 is housed in the inner cavity of the countersunk holes 53. Therefore, the mounting plate 2 will not be obstructed by the hexagon socket head cap screws 52 during the upward lifting process.

[0034] To facilitate the installation and energization of electrical components, this application also includes an electrical mounting bracket 24 fixedly installed on both the front and back sides of the mounting plate 2, which facilitates the installation of electrical components on the front and back sides of the mounting plate 2. Multiple exchange holes 25 are fixedly and vertically distributed at equal intervals in the middle of the surface of the mounting plate 2. The arrangement of the exchange holes 25 allows cables on both sides of the mounting plate 2 to pass through the mounting plate 2, so as to ensure that the electrical components on both sides of the mounting plate 2 can maintain a energized state.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
