Description

Technical Field

[0001] This utility model belongs to the field of electrical control cabinet technology, and in particular relates to a layered, pull-out electrical control cabinet bracket. Background Technology

[0002] An electrical control cabinet is a device for centralized control and protection of electrical equipment. It houses a large number of electrical devices, and the bracket is an important component of the electrical control cabinet. It is used to install and fix these electrical devices, providing a basic platform for the orderly, stable and safe installation of the entire system.

[0003] Chinese patent CN217934728U discloses an adjustable internal bracket power control cabinet. The patent describes a cabinet body with its lower inner wall connected to a screw shaft via a rolling bearing on the right side. The cabinet connects the bracket to the cabinet body using a screw, threaded cylinder, sliding rod, and through-hole. A fixed cylinder and insert rod connect the threaded cylinder to the slider. When using this device, the user can adjust the position of the bracket according to the size of the electrical components to be installed. The user connects the threaded cylinder of the bracket to the slider using the insert rod and fixed cylinder. Rotating the shaft uses bevel gears one and two to rotate the screw. When the screw rotates, the screw moves up and down via the threaded cylinder, fixed cylinder, insert rod, and slider. This solves the problem that most existing power control cabinets cannot adjust the position of the internal bracket, thus reducing the space utilization rate inside the control cabinet.

[0004] However, in the current solution, the tray is not easy to slide and pull out. During the maintenance or disassembly of electrical equipment, the operating space is limited due to the internal space of the cabinet, which is not conducive to the operation of the staff. Therefore, it is necessary to design a layered pull-out electrical control cabinet tray. Utility Model Content

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] Example 1 A preferred embodiment of the layered, pull-out electrical control cabinet bracket provided by this utility model is, for example... Figures 1 to 5 As shown: A layered, pull-out electrical control cabinet bracket includes a frame 1; sliding seats 2 disposed on both sides of the inner wall of the frame 1, with a sliding groove 4 on one side of the sliding seat 2, a slider 9 slidably connected inside the sliding groove 4, a main mounting plate 8 fixedly connected to one side of the slider 9, and auxiliary mounting plates 7 disposed at the top and bottom of the main mounting plate 8; an adjustment component 5 assembled on the frame 1, used to realize the up-and-down sliding adjustment of the sliding seat 2; a positioning component 3 assembled on the sliding seat 2, used to limit and fix the slider 9 after sliding; and a fixing component 6 assembled on the main mounting plate 8, used to limit and fix the auxiliary mounting plate 7 after sliding.

[0023] The positioning component 3 includes: a positioning groove 306 formed on the front of the slider 9; a slide rod 304 fixedly connected to the inner wall of the positioning groove 306; a slide block 307 slidably connected to the surface of the slide rod 304; a lever 301 fixedly connected to one end of the slide block 307; a positioning rod 303 fixedly connected to one end of the lever 301; a fixing spring 305 wound around the surface of the slide rod 304; the two ends of the fixing spring 305 being fixedly connected to the bottom wall of the positioning groove 306 and the bottom end of the slide block 307, respectively; and a positioning hole 302 formed on the top wall of the slide groove 4.

[0024] It should be noted that some existing layered pull-out electrical control cabinet brackets still have certain shortcomings in actual use. In comparison documents, the operating space is relatively limited due to the internal space of the cabinet during the inspection, maintenance or disassembly of electrical equipment, which is not conducive to the operation of the staff.

[0025] In this embodiment, the frame 1 is installed inside the electrical control cabinet. The sliding seat 2 can slide up and down using the adjusting component 5, facilitating changes in the spacing between the secondary mounting plates 7. This allows for adjustments based on different sizes of electrical equipment. Simultaneously, the fixing component 6 allows the secondary mounting plates 7 to slide up and down. External bolts and pre-drilled slots 10 are used to install the electrical equipment onto the secondary mounting plates 7 and the main mounting plate 8. Then, the lever 301 can be moved downwards, causing the sliding block 307 to slide down the surface of the sliding rod 304, compressing the fixing spring 305. When lever 301 slides down, it causes positioning lever 303 to slide down until it is completely disengaged from the positioning hole 302. Then, lever 301 is pushed, causing slider 9 to slide inside slide groove 4. This pushes the main mounting plate 8 and the electrical equipment mounted on it into the frame 1. When the electrical equipment needs to be repaired, lever 301 is pushed down and pulled, causing slider 9 to slide inside slide groove 4 and slide the main mounting plate 8. This allows the electrical equipment to be moved in front of the staff, avoiding the inconvenience of repairing the electrical equipment due to the limited space inside the cabinet.

[0026] In a further preferred embodiment of the present invention, the lever 301 is T-shaped, and one end of the lever 301 extends to the outside of the slide groove 4.

[0027] In this embodiment, a longer lever 301 is used to make it easier for staff to slide the lever 301.

[0028] In a further preferred embodiment of the present invention, the top end of the positioning rod 303 and the interior of the positioning hole 302 form an engaging structure, and there are two positioning holes 302.

[0029] In this embodiment, the main mounting plate 8 is limited and fixed after sliding back and forth inside the slide groove 4 by using the sliding of the positioning rod 303 and the positioning hole 302.

[0030] In a further preferred embodiment of the present invention, the adjusting component 5 includes: a limiting groove 505 formed on one side of the inner wall of the frame 1, and an adjusting groove 502 penetrating the frame 1 formed at one end of the inner wall of the frame 1; a limiting block 504 fixedly connected to the back of the sliding seat 2, and adjusting bolts 501 penetrating the adjusting groove 502 fixedly connected to the upper and lower ends of the front of the sliding seat 2; and a locking nut 503 threadedly connected to the surface of the adjusting bolt 501.

[0031] In this embodiment, the locking nut 503 is loosened by using a hex wrench, and then the sliding seat 2 is pushed so that the limiting block 504 slides up and down inside the limiting groove 505 and the adjusting bolt 501 slides up and down inside the adjusting groove 502. This changes the distance between the main mounting plates 8 to a suitable level. Then the locking nut 503 is tightened so that one end of it is pressed against the front of the frame 1 to achieve the limiting and fixing of the sliding seat 2 after it slides up and down.

[0032] In a further preferred embodiment of the present invention, a sliding structure is formed between the interior of the limiting block 504 and the limiting groove 505, and the limiting block 504 and the limiting groove 505 are convex in shape.

[0033] In this embodiment, the sliding of the convex limiting block 504 and the limiting groove 505 is used to improve the stability of the sliding seat 2 sliding up and down.

[0034] Example 2 Based on Embodiment 1, a preferred embodiment of the layered pull-out electrical control cabinet bracket provided by this utility model is, for example... Figures 1 to 4 As shown: The fixing component 6 includes: sliding grooves 605 that are equally spaced and symmetrically opened at the top and bottom of the main mounting plate 8; fixing grooves 603 that are equally spaced at the top and bottom of the front of the main mounting plate 8; fixing bolts 602 that extend into the sliding grooves 605 are movably connected to the inner wall of the fixing grooves 603; and sliding posts 604 that are equally spaced and fixedly connected to one end of the auxiliary mounting plate 7; and bolt holes 601 that are equally spaced on the front of the sliding posts 604 and are threaded to one end of the fixing bolts 602.

[0035] In this embodiment, the fixing bolt 602 is rotated with a screwdriver or other tools until it is completely disengaged from the bolt hole 601. Then, the auxiliary mounting plate 7 is pulled so that the sliding column 604 slides to a suitable distance inside the sliding groove 605. Then, the fixing bolt 602 is tightened in the opposite direction so that it is screwed into the appropriate bolt hole 601. This achieves the limiting and fixing of the sliding column 604 after sliding, thereby realizing the overall height of the two auxiliary mounting plates 7 and the main mounting plate 8 when unfolded, so that it can meet the installation requirements of different electrical equipment.

[0036] In a further preferred embodiment of the present invention, a sliding structure is formed between the interior of the sliding column 604 and the sliding groove 605, and the shapes of the sliding column 604 and the sliding groove 605 are cross-shaped.

[0037] In this embodiment, the cross-shaped sliding column 604 and sliding groove 605 are used to improve the smoothness of the sub-mounting plate 7 sliding up and down.

[0038] In a further preferred embodiment of this utility model, an O-ring is fixedly connected to the surface of the nut of the fixing bolt 602. The O-ring can improve the anti-slip friction between the nut of the fixing bolt 602 and the inner wall of the fixing groove 603, and prevent the threads of the fixing bolt 602 from loosening accidentally.

[0039] In a further preferred embodiment of the present invention, the auxiliary mounting plate 7 is provided with reserved grooves 10 at equal intervals, and the inner top wall and inner bottom wall of the reserved grooves 10 are semi-circular.

[0040] In this embodiment, the reserved slot 10 facilitates the installation of electrical equipment on the auxiliary mounting plate 7 and the main mounting plate 8 using external bolts.

[0041] In summary, by using the adjustment component 5 and the fixing component 6, the size of the electrical equipment can be adjusted to facilitate the installation and fixing of electrical equipment of different sizes. Furthermore, by using the sliding block 9 and the sliding groove 4, and in conjunction with the positioning component 3, the electrical equipment can be easily slid in front of the staff, avoiding the inconvenience caused by the limited space inside the cabinet for the staff to perform maintenance.
