Description

Technical Field

[0001] This utility model belongs to the field of electrical equipment technology, specifically a power distribution cabinet with a bottom buffer structure. Background Technology

[0002] A distribution cabinet is a specialized electrical device that integrates electrical components for centralized management, distribution, and protection of electrical energy. It is a crucial intermediate link between the power supply end and the electrical equipment. Distribution cabinets are widely used in various industries. Distribution cabinets are a general term for motor control centers, which are used in situations where the load is relatively dispersed and there are fewer circuits. Motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy of a certain circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.

[0003] Currently, traditional distribution cabinets in existing technologies mostly have rigid supports at the bottom. When subjected to impact, vibration or bumps during equipment operation, the vibration energy is easily transmitted to the electrical components inside the cabinet, causing loose wiring and contact oxidation, shortening the service life of the equipment, and in severe cases, causing circuit failure. Therefore, in order to address the above problems, a distribution cabinet with a bottom buffer structure is proposed. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a power distribution cabinet with a bottom buffer structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The power distribution cabinet with bottom buffer structure of this utility model includes a support base, a connecting seat and a power distribution cabinet. The bottom of the power distribution cabinet is fixedly connected to the top of the connecting seat. Mounting holes are opened at the four corners of the connecting seat. Buffer components are provided at the four corners of the support base. The buffer assembly includes sliding columns installed at the four corners of the support base. An arc-shaped spring plate is fitted on the surface of the sliding column. A spring is provided between the top and bottom of the arc-shaped spring plate. The arc-shaped spring plate passes through the mounting hole. A knob is provided on the top of the sliding column.

[0006] Preferably, the top of the arc-shaped spring plate can slide on the surface of the sliding column, and the four corners of the support base are provided with internal threaded grooves that match the bottom of the sliding column.

[0007] Preferably, the bottom of the connecting seat is fixedly connected to a stop block, the top of the support base is fixedly connected to a fixing column, the surface of the fixing column is rotatably connected to a gear, and the top of the gear is fixedly connected to an internally threaded column.

[0008] Preferably, the surface of the abutment is fixedly provided with a protrusion, the protrusion is matched with the internal threaded post, and the surface of the support base is slidably connected with a toothed plate, the gear meshing with the toothed plate.

[0009] Preferably, an airbag is fixed to the surface of the support base, and an air valve is provided on one side of the airbag, with the airbag corresponding to the toothed plate.

[0010] Preferably, a rubber pad is provided at the connection point between the surface of the connector and the distribution cabinet.

[0011] The beneficial effects of this utility model are: This utility model provides a power distribution cabinet with a bottom buffer structure. The connecting seat absorbs external vibrations and generates vertical displacement, which in turn squeezes the arc-shaped spring plate. The arc-shaped spring plate undergoes elastic deformation under compression, initially absorbing vibration energy. The top of the arc-shaped spring plate slides on the surface of the sliding column, causing the spring between its top and bottom to compress or stretch. The spring counteracts the vertical impact force through elastic restoring force, further weakening the vibration intensity and ultimately reducing the transmission of vibration into the power distribution cabinet, thus achieving core buffer protection.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0015] Specific implementation examples are given below.

[0016] Please see Figure 1 - Figure 3 This utility model provides a power distribution cabinet with a bottom buffer structure, including a support base 1, a connecting seat 2 and a power distribution cabinet 3. The bottom of the power distribution cabinet 3 is fixedly connected to the top of the connecting seat 2. Mounting holes are provided at the four corners of the connecting seat 2 for connecting with the support base 1. Buffer components are provided at the four corners of the support base 1. The buffer assembly includes sliding posts 201 installed at the four corners of the support base 1. An arc-shaped spring plate 204 is fitted onto the surface of the sliding post 201. The top of the arc-shaped spring plate 204 can slide on the surface of the sliding post 201 under pressure. A spring 203 is provided between the top and bottom of the arc-shaped spring plate 204. When the top of the arc-shaped spring plate 204 slides, the spring 203 can be compressed. The arc-shaped spring plate 204 passes through a mounting hole, which allows the connecting seat 2 to be installed with the support base 1. A knob is provided on the top of the sliding post 201. By aligning the bottom of the sliding post 201 with the internal threaded groove of the support base 1 and rotating the knob on the top of the sliding post 201, the sliding post 201 can be activated. The column 201 rotates, and the four corners of the support base 1 are provided with internal threaded slots. The internal threaded slots match the bottom of the sliding column 201. The sliding column 201 is rotated to engage with the threaded slots to achieve connection and fixation. The vibration energy is transmitted to the connecting seat 2 through the support base 1. The connecting seat 2 undergoes vertical displacement due to vibration. By compressing the arc-shaped spring plate 204, the arc-shaped spring plate 204 undergoes elastic deformation. The metal elasticity is used to buffer the vibration energy. At the same time, the spring 203 is compressed or stretched with the deformation of the arc-shaped spring plate 204. The elastic restoring force of the spring 203 offsets the vertical impact force, further weakening the vibration intensity, thereby achieving the function of buffering the distribution cabinet 3.

[0017] Furthermore, such as Figure 2 and Figure 3As shown, a stop block 301 is fixedly connected to the bottom of the connecting seat 2. When the connecting seat 2 is pressed down, the stop block 301 presses down synchronously with the connecting seat 2. A fixed column is fixedly connected to the top of the supporting base 1. A gear 303 is rotatably connected to the surface of the fixed column. An internally threaded column 302 is fixedly connected to the top of the gear 303. A protrusion is fixedly connected to the surface of the stop block 301. The protrusion matches the internally threaded column 302. When the stop block 301 presses down with the protrusion, the protrusion slides along the thread inside the internally threaded column 302, causing the internally threaded column 302 to rotate at a fixed point. The rotation of the internally threaded column 302 drives the bottom gear 303 to rotate synchronously. A toothed plate 304 is slidably connected to the surface of the support base 1. A gear 303 meshes with the toothed plate 304. Because the gear 303 and the toothed plate 304 are meshed, the fixed-point rotation of the gear 303 can drive the toothed plate 304 to slide radially. An airbag 305 is fixedly connected to the surface of the support base 1. An air valve is provided on one side of the airbag 305. The air pressure in the airbag 305 is adjusted by adjusting the air valve to adjust the buffering force. The airbag 305 corresponds to the toothed plate 304. When the toothed plate 304 slides, it can squeeze the airbag 305 because of the corresponding position. The gas in the airbag 305 is compressed and generates a reaction force, thereby buffering the overall impact force.

[0018] Furthermore, such as Figure 3 As shown, a rubber pad is provided at the connection between the surface of the connector 2 and the distribution cabinet 3. The rubber pad can ensure the seal between the distribution cabinet 3 and the connector 2, and also achieve the effect of shock absorption.

[0019] Working principle: First, the bottom of the sliding column 201 is matched with the threaded grooves on the four perimeter corners of the support base 1. Rotating the knob on the top of the sliding column 201 rotates the column and engages with the groove, completing the positioning of the buffer assembly. Then, the mounting hole of the connecting seat 2 is aligned with the sliding column 201, allowing the arc-shaped spring plate 204 to pass through the mounting hole. Simultaneously, the bottom of the distribution cabinet 3 is fixed to the top of the connecting seat 2. At this point, the rubber pads at the connection point are tightly fitted, preparing for subsequent buffering and shock absorption. When vibration is transmitted from the support base 1 to the connecting seat 2, the connecting seat 2 undergoes vertical displacement due to the vibration, thus compressing the arc-shaped spring plate 204. The arc-shaped spring plate 204 undergoes elastic deformation under compression, initially absorbing vibration energy. The top of the arc-shaped spring plate 204 slides on the surface of the sliding column 201, causing the spring 203 between its top and bottom to compress or stretch, further weakening the vibration intensity and ultimately reducing the transmission of vibration into the distribution cabinet 3, achieving core buffer protection. Simultaneously, when the connecting seat 2... When pressed down, the bottom fixed block 301 presses down synchronously. The protrusion on the surface of the block 301 slides along the internal threaded post 302 on the support base 1, causing the internal threaded post 302 to rotate at a fixed point. Since the internal threaded post 302 is fixed to the gear 303, the gear 303 rotates synchronously with the internal threaded post 302. Since the gear 303 meshes with the toothed plate 304 on the surface of the support base 1, the rotation of the gear 303 is converted into the radial sliding of the toothed plate 304. When the toothed plate 304 slides, it squeezes the corresponding airbag 305. The gas in the airbag 305 is compressed and generates a reaction force, further buffering the overall impact force. At the same time, the internal air pressure can be adjusted by the air valve on one side of the airbag 305 to flexibly control the buffering force. The rubber pad at the connection between the connecting seat 2 and the distribution cabinet 3 can ensure the sealing of the connection between the two to prevent dust and moisture from entering the interior of the distribution cabinet 3. On the other hand, it can absorb minor vibrations through its own elastic deformation, supplementing the deficiencies of the core and auxiliary buffers, and further protecting the stable operation of the internal components of the distribution cabinet 3.

[0020] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
