Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to an AC power distribution cabinet with a folding shock-absorbing bracket. Background Technology

[0002] In scenarios such as power systems, construction sites, and emergency power supply, AC distribution cabinets are widely used as core equipment for power distribution and control in fixed or mobile power supply systems. Traditional AC distribution cabinets usually adopt a box structure and are fixed to a concrete foundation or support with bolts to ensure operational stability and electrical safety. These distribution cabinets are often equipped with fixed legs or mounting bases and are suitable for indoor or long-term fixed locations.

[0003] With the increasing demand for rapid power supply in field construction, disaster relief, and temporary events, some distribution cabinets have begun to adopt movable designs, such as adding casters to the bottom of the cabinet or configuring simple support feet to improve deployment flexibility. However, these structures are mostly rigid connections, have a large overall volume, require a lot of space for transportation, and lack effective shock absorption measures. After the distribution cabinet is deployed outdoors or in temporary sites, environmental vibrations from the ground or slight oscillations generated by the operation of the equipment itself can easily be transmitted to the inside of the cabinet through the support structure. Over a long period of time, this may cause precision components such as circuit breakers to loosen, malfunction, or have a reduced lifespan, affecting the stability and safety of the power supply system.

[0004] Therefore, it is necessary to design an AC power distribution cabinet with a folding shock-absorbing bracket. Utility Model Content

[0005] In order to overcome the shortcomings of existing AC distribution cabinets, which are mostly rigidly connected, non-foldable, and lack shock absorption function, this utility model provides an AC distribution cabinet with a foldable shock absorption bracket.

[0006] The technical solution of this utility model is as follows: an AC power distribution cabinet with a folding shock-absorbing bracket, comprising a cabinet body, a connecting shaft, support legs, a damper, a shock-absorbing spring, a locking block, a snap-fit ​​groove, a handle, and an elastic element. The bottom left and right sides of the cabinet body are rotatably equipped with connecting shafts. Each connecting shaft has a sliding groove at its lower part, and support legs are slidably connected inside the groove. A damper is fixedly installed on the upper side of each groove. The lower telescopic end of each damper is connected to an adjacent support leg, and a shock-absorbing spring is connected between the support leg and the damper. The shock-absorbing spring is sleeved on the damper. Locking blocks are slidably connected to the bottom left and right sides of the cabinet body. A cross-shaped snap-fit ​​groove is opened on the front side of each connecting shaft, and the locking blocks are inserted into the corresponding snap-fit ​​grooves. A handle is fixedly connected to the front side of each locking block, and an elastic element is connected between the locking block and the cabinet body.

[0007] Furthermore, it also includes storage frames, handles, stops, and torsion springs. Storage frames are slidably connected to the lower left and right sides of the cabinet. A handle is fixed to one side of each storage frame. Stops are rotatably connected to the lower left and right sides of the cabinet. The stops block the outside of the storage frames, and torsion springs are connected between the stops and the cabinet. The torsion springs are all wrapped around the pivot of the stops.

[0008] Furthermore, it also includes limit plates, which are fixedly installed on both the left and right sides of the bottom of the cabinet. The limit plates are located on the inner side of the two connecting shafts respectively.

[0009] Furthermore, it also includes casters, with multiple casters installed at the bottom of the cabinet.

[0010] Furthermore, it also includes shock-absorbing pads, with shock-absorbing pads installed at the bottom of each support leg.

[0011] Furthermore, the casters are in contact with the ground when the support legs are folded, for support and movement; conversely, when the support legs are extended, the casters are detached from the ground, and the support legs provide support.

[0012] Beneficial effects:

[0013] 1. This utility model, by setting a support leg structure that can rotate around the connecting shaft, and in conjunction with the locking mechanism of the locking block and the snap-fit ​​groove, realizes the rapid unfolding and folding of the support bracket, reduces the volume of the equipment in the transportation and storage state, and improves space utilization and mobility.

[0014] 2. This utility model adopts a two-stage damping system with the synergistic effect of dampers and shock-absorbing springs. The support legs can move up and down in the connecting shaft slide groove to effectively absorb and isolate ground vibration and equipment operation oscillation, prevent vibration from being transmitted to the cabinet, ensure the stable operation of key components such as circuit breakers, and extend the service life of the equipment.

Detailed Implementation

[0021] Example: An AC power distribution cabinet with a folding shock-absorbing bracket, such as... Figures 1-5 As shown, the cabinet includes a cabinet body 1, a connecting shaft 2, support legs 3, a damper 4, a shock-absorbing spring 5, a locking block 6, a snap-fit ​​groove 101, a handle 7, and an elastic element 8. The bottom left and right sides of the cabinet body 1 are rotatably equipped with connecting shafts 2. The lower part of the connecting shaft 2 is provided with a sliding groove, and the support legs 3 are slidably connected inside the sliding groove. The upper side of the sliding groove is fixedly installed with a damper 4. The lower telescopic end of the damper 4 is connected to the adjacent support leg 3. The support leg 3 and the damper 4 are connected with a shock-absorbing spring 5. The shock-absorbing spring 5 is sleeved on the damper 4. The bottom left and right sides of the cabinet body 1 are slidably connected with locking blocks 6. The front side of the connecting shaft 2 is provided with a cross-shaped snap-fit ​​groove 101. The locking blocks 6 are inserted into the corresponding snap-fit ​​groove 101. The front side of the locking blocks 6 is fixedly connected with a handle 7. The locking blocks 6 and the cabinet body 1 are connected with an elastic element 8.

[0022] like Figure 2 and Figure 5 As shown, it also includes a storage frame 11, a handle 12, a stop block 13 and a torsion spring 14. The storage frame 11 is slidably connected to the lower left and right sides of the cabinet body 1. A handle 12 is fixed to one side of each storage frame 11. A stop block 13 is rotatably connected to the lower left and right sides of the cabinet body 1. The stop blocks 13 block the outside of the storage frame 11. A torsion spring 14 is connected between each stop block 13 and the cabinet body 1. The torsion spring 14 is wrapped around the pivot of its stop block 13.

[0023] like Figure 1 and Figure 2 As shown, it also includes a limiting plate 15. The limiting plates 15 are fixedly installed on the left and right sides of the bottom of the cabinet 1. The limiting plates 15 are located on the inner side of the two connecting shafts 2 respectively, and are used to limit the rotation angle of the connecting shafts 2 to prevent excessive unfolding.

[0024] like Figure 2 and Figure 3 As shown, it also includes casters 9. Multiple casters 9 are installed at the bottom of the cabinet 1. When the support leg 3 is in the folded state, the casters 9 are in contact with the ground for support and movement. Conversely, when the support leg 3 is unfolded, the casters 9 are off the ground, and the support leg 3 provides support to ensure operational stability. The two modes switch automatically, and the functions are highly integrated.

[0025] like Figure 1 and Figure 3 As shown, it also includes shock-absorbing pads 10. The bottom of each support leg 3 is equipped with shock-absorbing pads 10 to enhance the buffering performance of the equipment in contact with the ground, improve the shock absorption effect, and prevent slippage.

[0026] In actual use, when the AC distribution cabinet needs to be deployed to the field construction, emergency rescue or temporary event site, the operator can use the multiple casters 9 installed at the bottom of the cabinet 1 to push the cabinet 1 to the target position. The casters 9 make it easy to move flexibly and position accurately in complex terrain. After arriving at the work site, the operator manually pulls the handles 7 on both sides, which causes the locking block 6 to overcome the elastic force of the elastic element 8 and disengage from the cross-shaped locking groove 101 on the front side of the connecting shaft 2, thereby releasing the lock on the connecting shaft 2.

[0027] Subsequently, the operator rotates the connecting shaft 2 downwards around its hinge point with the cabinet 1, causing the support leg 3 in the slide groove to rotate outwards and downwards synchronously to a vertical position. During the unfolding process, the limiting plate 15 plays a crucial role in limiting the angle. When the connecting shaft 2 rotates to the predetermined unfolding angle, its rotation path is blocked by the limiting plate 15, preventing the support leg 3 from over-unfolding or rotating out of control, ensuring that the structure unfolds in place and is subjected to reasonable force, and avoiding mechanical damage to the connecting shaft 2 or the support leg 3 due to over-displacement. After the support leg 3 is fully unfolded and in a vertical support state, the handle 7 is released, the elastic element 8 rebounds, and pushes the locking block 6 to automatically insert into the cross-shaped snap-fit ​​groove 101, realizing a reliable lock between the connecting shaft 2 and the cabinet 1, ensuring the stability of the support structure.

[0028] At this time, the shock-absorbing pad 10 at the bottom of the support leg 3 contacts the ground and bears the main support force, while the caster wheel 9 is off the ground to avoid deformation or rolling due to the weight of the wheel, thus ensuring the stability of the distribution cabinet during operation. The support leg 3 slides up and down in the groove of the connecting shaft 2, and its movement path is controlled by the damper 4 and the shock-absorbing spring 5. When the cabinet 1 is subjected to ground vibration or its own oscillation, the support leg 3 can move up and down slightly along the groove. The damper 4 absorbs the vibration energy, and the shock-absorbing spring 5 provides elastic restoring force, forming a two-stage shock absorption mechanism, which effectively isolates the transmission of external vibration to the inside of the cabinet 1, protects the circuit breaker, relay and other precision electrical components, and prevents loosening, malfunction or fatigue damage.

[0029] When in transport or storage, the operator can pull handle 7 again to disengage locking block 6 from snap-fit ​​slot 101, rotate and fold connecting shaft 2 upwards, and support legs 3 will retract to the left and right sides of cabinet 1. The overall structure is compact, significantly reducing space occupation and facilitating loading and transportation or warehouse stacking. The lower part of cabinet 1 is also equipped with two storage boxes 11, which can be used to store tools, cable connectors, spare parts and other accessories. When in use, simply rotate stop block 13 to disengage it from the limit of storage box 11, and then pull handle 12 to pull out storage box 11. After use, push it back, improving the practicality of the equipment.
