[0002] As the core equipment for power distribution and control, distribution boxes are widely used in industrial, construction, municipal, and communication fields. Their main function is to house electrical components such as low-voltage circuit breakers and contactors, and to realize circuit switching control, overload protection, and leakage protection.

[0003] Currently, traditional distribution boxes are mostly made of a single welded or stamped steel plate, without special energy-absorbing structures on the side walls and top. When subjected to collisions, impacts from falling objects, or bumps during transportation, the box is prone to deformation, directly squeezing the internal electrical components, leading to loose wiring and component damage, and causing power outages. Utility Model Content

[0004] The purpose of this utility model is to provide an impact-resistant distribution box, which aims to solve the technical problem that the traditional distribution box body is mostly made of a single steel plate welded or stamped. When subjected to collisions, falling objects, or bumps during transportation, the body is prone to deformation, resulting in loose wiring and component damage, leading to power outage faults.

[0005] To achieve the above objectives, this utility model adopts an impact-resistant distribution box, including an outer box and an inner box. A bottom support assembly is provided between the bottom inner side of the outer box and the bottom outer side of the inner box, and a top energy-absorbing assembly is provided between the top inner side of the outer box and the top outer side of the inner box.

[0007] The bottom support assembly includes a positioning post, which is fixedly installed on the bottom inner side of the outer box. The outer side of the inner box is provided with a foot plate that is adapted to the positioning post, and the positioning post passes through the foot plate.

[0008] The positioning spring is sleeved on the outer side of the positioning column and is located below the foot plate.

[0009] A rubber support block is provided between the bottom of the inner side of the outer box and the bottom of the outer side of the inner box.

[0010] The top energy-absorbing component includes a sliding rod, which is fixedly installed on the top of the outer side of the inner box.

[0011] The sliding rod has an arc-shaped energy-absorbing plate on its outer side, with the inner arc-shaped side of the arc-shaped energy-absorbing plate close to the top of the outer side of the inner box, and the sliding rod passes through the arc-shaped energy-absorbing plate.

[0012] An energy-absorbing spring is fixedly installed between the top inner side of the outer casing and the outer arc-shaped side of the arc-shaped energy-absorbing plate.

Detailed Implementation

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] Please see Figures 1-4 ,in Figure 1 This is a structural schematic diagram of an impact-resistant distribution box according to this utility model. Figure 2 This is a front view of an impact-resistant distribution box according to this utility model. Figure 3 This is a structural cross-sectional view of an impact-resistant distribution box according to this utility model. Figure 4 This is a partial structural schematic diagram of an impact-resistant distribution box according to the present invention.

[0025] In this embodiment, a bottom support assembly is provided between the inner bottom of the outer casing 101 and the outer bottom of the inner casing 102, and a top energy absorption assembly is provided between the inner top of the outer casing 101 and the outer top of the inner casing 102. A reinforcing frame 103 is fixedly provided on the inner side wall of the outer casing 101, a first reinforcing rod 104 is fixedly provided inside the reinforcing frame 103, and a second reinforcing rod 105 is fixedly provided between the reinforcing frame 103 and the bottom of the inner wall of the outer casing 101. The inner side of the reinforcing frame 103 is fixedly connected to the outer side wall of the inner casing 102 through a lateral spring 106 and a buffer block 107. Guide rods 108 are also provided on both sides of the lateral spring 106 and fixedly connected to the buffer block 107, and the guide rods 108 penetrate the reinforcing frame 103. The outer casing 101 is an outer... The inner casing 102 is protected by a layer of reinforcement. The first reinforcing rod 104 and the second reinforcing rod 105 enhance the impact resistance of the reinforcing frame 103. When the outer casing 101 is impacted, the reinforcing frame 103 prevents the side wall of the outer casing 101 from being excessively deformed. At the same time, the lateral spring 106 absorbs the impact energy of the reinforcing frame 103 through compression deformation. The buffer block 107 is made of flexible material to prevent the lateral spring 106 from directly contacting the inner casing 102 rigidly. When the lateral spring 106 is compressed, the guide rod 108 slides within the reinforcing frame 103 to ensure that the buffer block 107 and the lateral spring 106 move laterally, preventing the buffer block 107 from shifting after the impact and causing the telescopic inner casing 102 to tilt.

[0026] The bottom support assembly includes a positioning post 109, which is fixedly disposed on the bottom inner side of the outer box 101. The outer side of the inner box 102 is provided with a foot plate 110 adapted to the positioning post 109, and the positioning post 109 passes through the foot plate 110. The inner box 102 is disposed on the outside of the positioning post 109 through the foot plate 110, which restricts the inner box 102 and prevents the inner box 102 from shifting laterally when it is impacted.

[0027] Secondly, a positioning spring 111 is sleeved on the outer side of the positioning post 109. The positioning spring 111 is located below the foot plate 110. When the distribution box is subjected to a vertical impact, the inner box 102 presses down on the telescopic foot plate 110, and the foot plate 110 compresses the positioning spring 111. The positioning spring 111 deforms to absorb the impact energy. After the impact disappears, the positioning spring 111 elastically resets, driving the foot plate 110 and the inner box 102 back to their initial positions.

[0028] Meanwhile, a rubber support block 112 is provided between the inner bottom of the outer box 101 and the outer bottom of the inner box 102. The support block is made of highly elastic rubber and is used to assist in supporting the weight of the inner box 102, avoid long-term fatigue of the positioning spring 111, and absorb slight vertical vibrations. This creates a synergistic effect of light vibration rubber absorbing energy and heavy vibration spring absorbing energy with the positioning spring 111.

[0029] Additionally, the top energy-absorbing assembly includes a sliding rod 113, which is fixedly mounted on the top outer side of the inner box 102. An arc-shaped energy-absorbing plate 114 is mounted on the outer side of the sliding rod 113, with the inner arc-shaped side of the arc-shaped energy-absorbing plate 114 close to the top outer side of the inner box 102. The sliding rod 113 passes through the arc-shaped energy-absorbing plate 114. An energy-absorbing spring 115 is fixedly mounted between the top inner side of the outer box 101 and the outer arc-shaped side of the arc-shaped energy-absorbing plate 114. When the top of the outer box 101 is impacted, the external force first acts on the top of the outer box 101 and is transmitted to the energy-absorbing spring 115. The energy-absorbing spring 115 is compressed and deformed to absorb the impact energy. At the same time, the arc-shaped energy-absorbing plate 114 transmits the dispersed force to the energy-absorbing spring 115, preventing the energy-absorbing spring 115 from being overloaded locally. After the impact disappears, the energy-absorbing spring 115 resets, causing the arc-shaped energy-absorbing plate 114 to return to its initial position.

[0030] In addition, the inner box 102 is provided with a door 116, and a buffer strip 117 is provided at the joint between the door 116 and the inner box 102. The buffer strip 117 is made of elastic rubber. The buffer strip 117 buffers the impact force between the door 116 and the inner box 102, avoids deformation of the door 116 or damage to the sealing structure, and fills the gap between the door 116 and the telescopic inner box 102, thereby helping to improve the waterproof and dustproof performance of the inner box 102.

[0031] Using an impact-resistant distribution box according to this embodiment, by setting up an outer casing 101, a telescopic inner casing 102, a bottom support assembly, and a top energy-absorbing assembly, in specific use, when the side wall of the outer casing 101 is subjected to impact force, the reinforcing frame 103, the first reinforcing rod 104, and the second reinforcing rod 105 disperse the force, preventing deformation of the outer casing 101. The remaining impact force is transmitted to the lateral spring 106, which absorbs energy. The guide rod 108 restricts the displacement direction of the buffer block 107. After the impact, the telescopic lateral spring 106 returns to its original position. When the top of the outer casing 101 is impacted... The top of the outer casing 101 receives external force and transmits it to the energy-absorbing spring 115. The energy-absorbing spring 115 compresses to absorb energy, while the arc-shaped energy-absorbing plate 114 distributes the concentrated force across the entire plate surface to prevent the energy-absorbing spring 115 from overloading. The sliding rod 113 restricts the displacement of the energy-absorbing plate. After impact, the energy-absorbing spring 115 and the arc-shaped energy-absorbing plate 114 reset. When there is a bump, the positioning spring 111 compresses to absorb energy, the rubber support block 112 assists in absorbing minor vibrations, and the positioning spring 111 resets. This improves the impact resistance of the distribution box and effectively avoids damage to the equipment inside the distribution box.

[0032] The above-disclosed embodiment is merely a preferred embodiment of the impact-resistant distribution box of this utility model, and should not be construed as limiting the scope of the 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 this utility model still fall within the scope of the utility model.
