Figure 3 This is a structural schematic diagram of the mounting bracket and fixing components of this utility model.

[0018] This utility model provides an electrical control cabinet that is easy to maintain. The cabinet body 101 is a rectangular hollow structure with an opening on one side, made of cold-rolled steel plate, and has good structural strength and impact resistance. The cabinet body 101 is hinged to the opening end by a door 102. The door 102 is sized to fit the opening of the cabinet body 101. A buckle is provided on the side of the door 102 away from the hinge end, and a corresponding slot is provided on the cabinet body 101. The door 102 is closed and locked by the engagement of the buckle and the slot. The inner side of the box door 102 is also affixed with a sealing strip, which can effectively prevent external dust and moisture from entering the box body 101 when closed; the extension plate 103 is integrally formed and fixed to the outer side of the bottom of the box body 101. The extension plate 103 is on the same horizontal plane as the bottom of the box body 101, and the length, width and height of the extension plate 103 are consistent with the bottom of the box body 101, which is used to provide an outward support base for the moving plate 104 during maintenance; two first sliding grooves 109 are symmetrically arranged at both ends of the bottom of the box body 101 along the length direction. The first slide groove 109 has a convex groove structure. Two second slide grooves 110 are provided on the extension plate 103 at positions corresponding to the first slide groove 109. The width and depth of the second slide grooves 110 are exactly the same as the first slide groove 109, and they are connected to each other to form a complete sliding track. The moving plate 104 has a rectangular flat plate structure, and its dimensions are adapted to the bottom cavity of the housing 101. Multiple pulleys 115 are fixed at both ends of the lower part of the moving plate 104, and the multiple pulleys 115 are evenly distributed... The pulleys 115, located on both sides of the movable plate 104, are adapted to the sliding grooves and can roll back and forth along the first sliding groove 109 and the second sliding groove 110, driving the movable plate 104 to move between the bottom of the housing 101 and the extension plate 103. The movable plate 104 is provided with an installation component and a fixing component for limiting the position. The installation component includes a mounting bracket for installing electrical equipment, and a fixing seat 105 is welded below the mounting bracket. The fixing seat 105 is detachably connected to the movable plate 104 by a plurality of bolts 106.

[0019] Furthermore, the fixing component includes a limiting rod 112 that slides vertically through the moving plate 104, a moving block 113 is provided at the upper end of the limiting rod 112, a return spring 114 is provided between the moving plate 104 and the moving block 113, and a first limiting hole 116 and a second limiting hole 111 adapted to the limiting rod 112 are respectively provided at the bottom of the housing 101 and on the extension plate 103.

[0020] In this embodiment, the fixing component is used to limit the position of the movable plate 104 to prevent it from moving arbitrarily during equipment operation or maintenance. It includes the limiting rod 112, the moving block 113, and the return spring 114. The limiting rod 112 is a cylindrical metal rod that slides vertically through the movable plate 104 and can move up and down along it. The moving block 113 is a circular block structure welded to the upper end of the limiting rod 112, with a diameter / side length greater than the diameter of the limiting rod 112 for easy gripping and control by the operator. The return spring 114 is sleeved on the outside of the limiting rod 112, located between the movable plate 104 and the moving block 113. Both ends of the return spring 114 are welded and fixed to the upper surface of the movable plate 104 and the lower surface of the moving block 113, respectively. In its natural state, the... The return spring 114 pushes the lower end of the limiting rod 112 into the first limiting hole 116 or the second limiting hole 111 through its elastic force, thereby fixing the moving plate 104. The first limiting hole 116 is provided at the bottom of the housing 101 near the opening end, and the second limiting hole 111 is provided at the end of the extension plate 103 away from the housing 101. The diameters of the first limiting hole 116 and the second limiting hole 111 are both adapted to the diameter of the limiting rod 112. When the moving plate 104 is completely inside the housing 101, the lower end of the limiting rod 112 is inserted into the first limiting hole 116 to fix the moving plate 104. When the moving plate 104 is completely moved out onto the extension plate 103, the lower end of the limiting rod 112 is inserted into the second limiting hole 111 to fix the position of the moving plate 104.

[0021] Furthermore, the mounting bracket includes a rectangular frame 107, within which a vertical linear array of support crossbars 108 for mounting electrical equipment is arranged.

[0022] In this embodiment, the mounting bracket consists of a rectangular frame 107 and a supporting crossbar 108. The height of the rectangular frame 107 is 4 / 5 of the height of the housing 101, and its width is adapted to the width of the movable plate 104. The supporting crossbar 108 is arranged in a linear array along the vertical direction inside the rectangular frame 107. The rectangular frame 107 and the supporting crossbar 108 are made of cold-rolled steel, which has high strength, excellent rust resistance, and is easy to drill holes in for installing electrical equipment.

[0023] Furthermore, the fixing base 105 has a trapezoidal structure that is smaller at the top and larger at the bottom.

[0024] In this embodiment, the fixing base 105 is welded to the bottom of the rectangular frame 107, forming a trapezoidal structure with a smaller top and a larger bottom. The width of the upper base of the trapezoid is the same as the width of the bottom of the mounting bracket, and the width of the lower base is wider than the upper base. The bottom of the fixing base 105 has four threaded holes, and the moving plate 104 has matching threaded holes at corresponding positions. Multiple bolts 106 are threaded through the bolt holes of the fixing base 105 and the threaded holes of the moving plate 104 to achieve detachable fixing of the mounting bracket and the moving plate 104, which facilitates the individual disassembly and maintenance of the mounting bracket.

[0025] Working principle:

[0026] When electrical equipment needs to be repaired, first open the enclosure door 102, and pull the movable block 113 upwards by hand. The movable block 113 drives the limiting rod 112 to move upwards, and the return spring 114 is stretched, causing the lower end of the limiting rod 112 to disengage from the first limiting hole 116, thus releasing the limitation on the movable plate 104. Then, pull the movable plate 104 outwards, and the multiple pulleys 115 roll along the first sliding groove 109 to the second sliding groove 110, causing the movable plate 104 and the mounting bracket to gradually move out of the enclosure 101 until the movable plate 104 completely slides to the extension plate 1. 03. At this point, the moving block 113 is released, the reset spring 114 returns to its natural state, and pushes the lower end of the limiting rod 112 into the second limiting hole 111 on the extension plate 103, thus fixing the moving plate 104 again. At this point, the mounting bracket and the electrical equipment above it are fully exposed outside the housing 101, and maintenance personnel can obtain sufficient operating space above and around the extension plate 103 to conveniently perform equipment maintenance, replacement, and other operations. After maintenance is completed, the above reverse operation is repeated to move the moving plate 104 and the mounting bracket back into the housing 101 and fix them.

[0027] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
