Description

Technical Field

[0001] This utility model belongs to the field of distribution box technology, specifically a distribution box side plate reinforcement structure. Background Technology

[0002] In modern industrial and infrastructure construction, distribution boxes, as one of the core devices of the power system, are widely used in building automation, industrial control, smart grids and various electrical facilities. Distribution boxes are usually composed of multiple side panels, front and rear doors, top cover and bottom plate, and are equipped with key electrical components such as cables, circuit breakers, and busbars. Such equipment must withstand large mechanical stresses, including the impact forces generated during transportation and installation.

[0003] Patent CN220754122U2 discloses a distribution box, belonging to the category of power distribution equipment. It includes a side-opening metal cabinet with electronic components installed inside. The bottom plate of the cabinet has an opening in the middle as a cable inlet / outlet. Mounting base plates are provided on the left and right side walls of the cabinet. A horizontal mounting groove is provided on the upper part of the mounting base plate, with one end of the groove open. A fixing groove is provided near the back of the cabinet, with its upper end connected to the inner end of the mounting groove. A mounting rod is installed within the fixing groove, with both ends horizontally positioned and connected to the fixing grooves of the mounting base plates on the left and right sides of the cabinet. Side mounting plates are provided on both sides of the cabinet, with their upper ends movably embedded into the mounting grooves of the mounting base plates. This utility model features a novel concept, ingenious design, reasonable layout, flexible configuration, convenient assembly and disassembly, good safety performance, and significant effects. However, the side panels were not adequately reinforced and were designed as simple flat panels, which made them prone to bending or deformation when faced with external mechanical stress and environmental changes, thus affecting the stability and service life of electrical equipment. Therefore, we proposed a reinforcement structure for the side panels of the distribution box. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides the following technical solution: a side panel reinforcement structure for a distribution box, comprising a side panel body, a support beam disposed within the side panel body, a reinforcement bracket disposed within the side panel body, the reinforcement bracket being distributed at the four corners inside the side panel body, a shock-absorbing pad disposed within the side panel body, the shock-absorbing pad being disposed between the side panel body and the support beam, a temperature stress relief hole being provided on the side panel body, the temperature stress relief hole being elliptical in shape, a cable support groove disposed on the side panel body, a reinforcing rib being provided at the bottom of the cable support groove, one side of the reinforcing rib being connected to the cable support groove, and the other side being connected to the side panel body.

[0005] Preferably, the support beam includes multiple support units with a cross-shaped cross section, which helps to provide higher bending and shear strength in multiple directions and ensures that the side plate remains stable when subjected to multi-directional stress.

[0006] Preferably, the reinforcing bracket is a triangular prism, which can provide additional rigidity to the corner of the side plate and effectively disperse external forces to prevent structural instability or damage.

[0007] Preferably, there are multiple shock-absorbing pads arranged in an array, and all of the shock-absorbing pads are made of an elastic material, such as rubber, silicone, or polyurethane, which can absorb and dampen external vibrations, protect the equipment from impact, and improve its shock resistance.

[0008] Preferably, there are multiple temperature stress relief holes, which are evenly distributed on the upper part of the side plate body and arranged along the length of the side plate body to form a relief zone, which can more efficiently release the stress caused by temperature difference and promote internal air circulation.

[0009] Preferably, each of the multiple temperature stress relief holes is provided with a folded edge structure to improve the strength of the area around the hole, prevent structural damage caused by stress concentration, and provide additional protection.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] During operation, external forces are evenly transmitted to the entire side panel body through the support beam structure, preventing local bending or deformation of the side panel and providing overall structural rigidity. The reinforced bracket provides stable compressive and torsional resistance, preventing corner deformation and overall instability of the side panel. When external vibration or impact occurs, the damping pads absorb and attenuate vibration energy through elastic deformation, reducing the impact force transmitted to the side panel and internal electrical equipment, protecting the equipment from vibration damage. When the temperature inside and outside the distribution box changes, the material will expand and contract thermally. The temperature stress relief holes can alleviate the stress caused by temperature changes and prevent side panel deformation. Furthermore, the reinforcing ribs enhance the deformation resistance of the cable support groove, ensuring that the cable remains stable when the cable is under heavy load or subjected to external impact, preventing loosening or damage. It can prevent the side panel from bending or twisting, ensuring that the distribution box remains stable under various forces and can absorb and attenuate energy, reducing the vibration transmission to the side panel and internal electrical equipment, thereby protecting sensitive equipment and extending its service life.

[0019] The reinforcing bracket 3 is a triangular prism, which can provide additional rigidity to the corners of the side plate and effectively disperse external forces to prevent structural instability or damage.

[0020] There are multiple shock-absorbing pads 4 arranged in an array. All of the shock-absorbing pads 4 are made of elastic material, such as rubber, silicone, or polyurethane. They can absorb and dampen external vibrations, protect the equipment from impact, and improve its seismic performance.

[0021] There are multiple temperature stress relief holes 5, which are evenly distributed on the upper part of the side plate body 1. The multiple temperature stress relief holes 5 are arranged along the length of the side plate body 1 to form a relief zone, which can release the stress caused by temperature difference more efficiently and promote internal air circulation.

[0022] Multiple temperature stress relief holes 5 are provided with folded edge structures 8 to improve the strength of the area around the holes, prevent structural damage caused by stress concentration, and provide additional protection.

The reinforcing bracket 3 provides stable compressive and torsional resistance, preventing corner deformation and overall instability of the side plate. When external vibration or impact occurs, the damping pad 4 absorbs and attenuates vibration energy through elastic deformation, reducing the impact force transmitted to the side plate and internal electrical equipment, protecting the equipment from vibration damage.

It can prevent the side plate from bending or twisting, ensuring that the distribution box can remain stable under various forces, and can absorb and attenuate energy, reducing the vibration transmitted to the side plate and internal electrical equipment, thereby protecting sensitive equipment and extending its service life.
