Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to a mounting ear structure for a power distribution cabinet. Background Technology

[0002] As an important electrical device in the power system, the design of the mounting lug structure of the distribution cabinet directly affects the installation efficiency and operational stability of the equipment. In the fields of industrial and civil power distribution, the distribution cabinet needs to be compatible with electrical components of different specifications and installation environments, which puts forward higher requirements for the versatility and reliability of the mounting lug structure.

[0003] Traditional distribution cabinet mounting lugs often use a fixed size design. In actual installation, due to differences in cabinet dimensions produced by different manufacturers, or the high requirements for hole accuracy in the installation environment, the mounting lugs are difficult to adapt to non-standard cabinets. On-site modification or replacement of parts is often required, resulting in low installation efficiency and high cost. At the same time, the rigid contact of existing mounting lugs can easily cause wear on the equipment surface, affecting the appearance and service life of the equipment. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Reference Figures 1 to 4 As shown, this utility model provides a technical solution: a mounting lug structure for a power distribution cabinet, including a base plate 1, a movable cavity 17 at one end of the base plate 1, fixed plates 8 fixedly connected to both sides of the movable cavity 17, a limit rod 9 threadedly connected to the surface of the fixed plate 8, a support frame 3 slidably connected to the inner wall of the movable cavity 17, a lower pressure plate 12 fixedly connected to the top of the support frame 3, and limit holes 11 opened on both sides of the support frame 3. The size of the limit hole 11 is adapted to the size of the limit rod 9. By sliding the support frame 3 in the movable cavity 17 and then inserting the limit rod 9 into the limit hole 11 at different positions, the lateral position of the support frame 3 can be adjusted to meet the size adaptation requirements of different power distribution cabinet installation scenarios. At the same time, through the threaded engagement of the limit rod 9 and the limit hole 11, sufficient locking force can be provided to prevent the support frame 3 from shifting under force and ensure the stability of the mounting lug structure.

[0025] Reference Figure 2 and Figure 3 As shown in this embodiment: side plates 2 are fixedly connected to both sides of the base plate 1. The surface of the side plate 2 is provided with an adjustment groove 4. The inner wall of the adjustment groove 4 is provided with a sliding groove 5. The inner wall of the sliding groove 5 is slidably connected with a sliding seat 6. The surface of the sliding seat 6 is provided with screw holes 7. By sliding the sliding seat 6 up and down along the adjustment groove 4, the position of the screw holes 7 on the sliding seat 6 can be finely adjusted, thereby adapting to cabinets with different installation hole positions and improving the adaptability of the device. One end of the limit rod 9 is fixedly connected with a knob 10. The surface of the knob 10 is provided with anti-slip texture. The limit rod 9 can be manually tightened or loosened by turning the knob 10. The anti-slip texture on the surface can prevent the user's hand from slipping.

[0026] Reference Figure 4As shown, specifically, a pressure groove 13 is provided on the lower surface of the pressure plate 12. Multiple elastic plates 14 are fixedly connected to the inner wall of the pressure groove 13. A soft pad 15 is fixedly connected to the lower surface of the multiple elastic plates 14. By setting the elastic plates 14, the X-shaped elastic plates 14 can reduce the impact force generated during installation through deformation, avoiding the impact on the internal components of the cabinet. At the same time, when the elastic rubber soft pad 15 contacts the surface of the equipment, it can avoid surface wear caused by hard contact and protect the appearance of the equipment. The cross-section of the elastic plate 14 is "X" shaped, and the material of the soft pad 15 is elastic rubber. A reinforcing rib 16 is fixedly connected at the connection between the pressure plate 12 and the support frame 3. The cross-section of the reinforcing rib 16 is triangular. By setting the reinforcing rib 16, the pressure borne by the pressure plate 12 can be effectively distributed, preventing the connection from deforming or breaking due to long-term stress, and improving the durability of the hanging ear structure.

[0027] Working principle: During operation, the support frame 3 is first pulled to slide within the moving cavity 17 of the base plate 1. Then, the limiting rod 9 on the fixed plate 8 is inserted into the limiting holes 11 at different positions to precisely adjust its lateral position, adapting to the installation requirements of different distribution cabinets. The threaded engagement between the limiting rod 9 and the limiting hole 11 provides reliable locking force to prevent the support frame 3 from shifting. Simultaneously, by moving the sliding seat 6 in the adjustment groove 4, the position of the screw holes 7 on its surface can be finely adjusted, thereby solving the problem of vertical installation hole deviation in the cabinet and widening the installation adaptability range. After adjustment, the fixing screws are inserted into the screw holes 7 and the mounting screws are installed. Inside the mounting hole, screws are tightened using an installation tool, causing the lower pressure plate 12 to press against the surface of the distribution cabinet. The elastic plate 14 in the lower pressure groove 13 can reduce the impact force generated during installation through deformation, avoiding damage to the internal components of the cabinet. At the same time, when the elastic rubber pad 15 contacts the equipment surface, it can avoid surface wear caused by hard contact, protecting the appearance of the equipment. In addition, the triangular reinforcing rib 16 at the connection between the lower pressure plate 12 and the support frame 3 can enhance the rigidity of the connection by dispersing pressure, preventing deformation or breakage caused by long-term stress, and ensuring the stability and durability of the hanging ear structure under heavy load conditions.
