[0001] The present application relates to the field of AC low-voltage power distribution cabinets, and in particular to a protective shock-absorbing AC low-voltage power distribution cabinet. Background Art

[0002] The power distribution cabinet is the final equipment of the power distribution system. The AC low-voltage power distribution cabinet is used for power conversion, distribution and control of power, lighting and distribution equipment.

[0003] In the process of implementing this application, the inventors found that there are at least the following problems in this technology: the electrical equipment in the distribution cabinet will generate vibrations. When large vibrations occur, it is easy to cause damage to the distribution cabinet and the electrical equipment in the distribution cabinet, which needs to be improved. Summary of the invention

[0004] In order to improve the seismic performance of a power distribution cabinet, the present application provides a protective shock-absorbing AC low-voltage power distribution cabinet.

[0005] The present application provides a protective shock-absorbing AC low-voltage distribution cabinet adopts the following technical solution:

[0006] A protective shock-absorbing AC low-voltage distribution cabinet comprises a cabinet body, a base and a shock-absorbing mechanism, wherein the base is arranged below the cabinet body, the shock-absorbing mechanism comprises a shock-absorbing spring arranged between the cabinet body and the base, and two ends of the shock-absorbing spring are respectively arranged on the cabinet body and the base.

[0007] By adopting the above technical solution, when the electrical equipment in the cabinet vibrates, the shock-absorbing spring plays a shock-absorbing role. Through the expansion and contraction of the shock-absorbing spring, the cabinet shakes slightly to minimize damage to the distribution cabinet and the electrical equipment in the distribution cabinet, thereby improving the seismic performance of the distribution cabinet.

[0008] Optionally, the base is provided with an adjustment groove for the end of the shock-absorbing spring to extend and retract, and the shock-absorbing mechanism also includes an adjustment block slidably arranged in the adjustment groove and a stop adjustment structure, one end of the shock-absorbing spring is arranged on the adjustment block, and the stop adjustment structure is used to limit the sliding of the adjustment block.

[0009] By adopting the above technical solution, the length of the shock-absorbing spring extending out of the adjustment slot when it is in a natural state can be adjusted by sliding the adjustment block and selecting the adjustment block to slide through the stop adjustment structure. The longer the length of the adjustment spring telescopic adjustment slot, the stronger the anti-seismic performance of the cabinet, but the greater the shaking amplitude caused by the resistance to vibration. The shorter the length of the adjustment spring extending out of the adjustment slot, the weaker the anti-seismic performance of the cabinet, but the smaller the shaking amplitude caused by the resistance to vibration. When it is only used to reduce the vibration caused by the operation of electrical equipment, the length of the adjustment spring extending out of the adjustment slot is reduced. When the working environment of the distribution cabinet has large vibrations, the length of the adjustment spring extending out of the adjustment slot is increased. Through the above structure, the distribution cabinet can be suitable for environments with different vibration intensities, thereby improving the adaptability of the distribution cabinet of the present application.

[0010] Optionally, the stop adjustment structure includes an adjusting screw, a support block fixed on the side wall of the adjusting block, and a guide groove opened on the wall of the adjusting slot hole, the adjusting screw passes through and is threadedly connected to the adjusting block, the support block is slidably set in the guide groove, and the guide groove extends along the sliding direction of the adjusting block.

[0011] By adopting the above technical solution, when the adjusting block is driven to move, the adjusting screw is rotated, and since the support block is slidably arranged in the guide groove, the adjusting block is restricted from rotating with the adjusting screw, so that the adjusting block can slide in the adjusting groove when the adjusting screw rotates. The adjusting block is driven to move by the adjusting screw, the structure is simple, and the movement of the adjusting block is stable.

[0012] Optionally, the stop adjustment structure also includes an upper stable groove and a lower stable groove opened on the wall of the adjustment slot hole, the upper stable groove and the lower stable groove are both used for the sliding setting of the support block, the height of the upper stable groove is greater than that of the lower stable groove, the extension direction of the lower stable groove is opposite to that of the upper stable groove, and the guide groove connects the upper stable groove and the lower stable groove.

[0013] By adopting the above technical solution, when the power distribution cabinet of the present application is used to resist the vibration emitted by the electrical equipment, the adjusting screw is rotated to move the adjusting block downward until the support block is flush with the lower stable groove, and then the adjusting screw is continued to be rotated, and the support block moves into the lower stable groove. When the power distribution cabinet of the present application is used to resist the vibration in the working environment of the power distribution cabinet, similarly, the adjusting screw is rotated to move the support block into the upper stable groove. Compared with supporting the adjusting block only by the adjusting screw, the stability of the adjusting block when locked is improved by the lower stable groove, the upper stable groove and the support block.

[0014] Optionally, a linkage mechanism is also included, and the anti-vibration mechanism is provided with multiple groups. The linkage mechanism includes multiple worms, multiple worm wheels, multiple synchronous wheels respectively connected to different worms, and a synchronous belt mounted on each synchronous wheel. Each of the worm wheels is respectively connected to a different adjusting screw, and each of the worms is respectively meshed with an adjacent worm wheel.

[0015] By adopting the above technical solution, when moving the adjustment block, only one of the worms needs to be rotated, and the above worm drives the other worms to rotate through the synchronous wheel, the synchronous belt and the synchronous wheels on the other worms, so that the worms rotate synchronously, and the worms drive the adjustment screws to rotate synchronously through the worm wheels, so that the adjustment blocks move synchronously. The linkage mechanism improves the simplicity of moving the adjustment block.

[0016] Optionally, one of the worms is provided with a toothed groove, a rotation groove is provided at the bottom of the toothed groove, the linkage mechanism includes an operating rod slidably arranged on the base along the axial direction of the worm and a linkage gear arranged on the operating rod, the groove wall of the toothed groove is used to engage with the linkage gear, and the rotation groove is used for the linkage gear to be rotated.

[0017] By adopting the above technical solution, when the worm is driven to rotate by the operating rod, the operating rod is pulled, and the operating rod drives the linkage gear to move, so that the linkage gear moves into the toothed groove and meshes with the groove wall of the toothed groove. At this time, the operating rod is turned, and the operating rod drives the worm to rotate through the gear and the groove wall of the toothed groove. After the adjustment is completed, the operating rod is pushed to move the linkage gear into the rotation groove. At this time, even if the operating rod is turned, the worm will not rotate, and the adjustment block is avoided as much as possible from moving due to accidental touching of the operating rod after the adjustment of the adjustment block is completed.

[0018] Optionally, a locking mechanism is further included, which includes a connecting rod and a locking block. The connecting rod is fixed to the bottom wall of the cabinet, and the base is provided with a sliding groove for the connecting rod to be slidably set in the telescopic groove and for the locking block to be slidably set. The cross-sectional area of ​​the telescopic groove is larger than the cross-sectional area of ​​the connecting rod. The telescopic groove is connected to the sliding groove, and the connecting rod is provided with a locking groove for inserting the end of the locking block.

[0019] By adopting the above-mentioned technical solution, when inspecting the cabinet or installing the power distribution cabinet of the present application, slide the locking block so that the end of the locking block is inserted into the locking groove, thereby limiting the connecting rod from sliding up and down in the telescopic groove, and further limiting the cabinet from moving up and down relative to the base, so as to facilitate the staff to inspect the cabinet or install the power distribution cabinet of the present application.

[0020] Optionally, a magnet is fixed to the bottom of the locking groove, and the magnet and the locking block attract each other.

[0021] By adopting the above technical solution, when the end of the locking block is inserted into the locking groove, the locking block and the magnet attract each other, thereby limiting the end of the locking block from being pulled out of the locking groove, thereby improving the stability of the locking block when limiting the movement of the connecting rod.

[0022] Optionally, the locking mechanism also includes a interlocking assembly, which includes a stop block fixed on the locking block, a interlocking block slidably set on the base, and a hook block fixed on the interlocking block. The axial direction of the operating rod is consistent with the extension direction of the sliding groove, and the sliding direction of the interlocking block is perpendicular to the sliding direction of the locking block. The operating rod is provided with a interlocking groove for the end of the interlocking block to extend into and slide into. When the end of the interlocking block is inserted into the interlocking groove, the linkage gear is located in the rotating groove, and the operating rod is provided with a yield groove for the operating rod to slide into. When the end of the locking block is inserted into the locking groove and contacts the magnet, the stop block contacts the hook block. When the end of the locking block moves out of the locking groove, the locking block can move until the yield groove is aligned with the operating rod.

[0023] By adopting the above technical solution, when the end of the locking block is inserted into the locking groove, the stopper block contacts the hook block, thereby playing a role of blocking the hook block to limit the movement of the interlocking block, and the end of the interlocking block is inserted into the interlocking groove to limit the sliding of the operating rod. At this time, the linkage gear is located in the rotation groove, and even if the operating rod is rotated, the worm cannot be driven to rotate. When the end of the locking block is pulled out of the locking groove, the interlocking block is moved to align the clearance groove with the operating rod. At this time, the operating rod can be pulled to move, so that the linkage gear can be moved into the tooth groove. Through the above structure, when the locking block locks the connecting rod, it cannot be adjusted by the operating rod. Only after the locking block is pulled out of the locking groove can it be adjusted from the operating rod. When the end of the operating rod moves into the clearance groove, that is, the operating rod can drive the worm to rotate through the linkage gear, the locking block cannot lock the connecting rod.

[0024] Optionally, the interlocking assembly also includes a interlocking spring. When the interlocking spring is in a natural state, the give way groove is aligned with the operating rod. A interlocking inclined surface is provided between the end surface of the hook block facing away from the connecting rod and the end surface of the hook block facing the operating rod. The interlocking inclined surface is used to interfere with the block. When the end of the locking block is inserted into the locking groove, the attraction between the magnet and the locking block is greater than the elastic force of the interlocking spring.

[0025] By adopting the above technical solution, the locking block is slightly pulled out of the locking groove, so that the attraction between the locking block and the magnet is less than the elastic force of the interlocking spring. The interlocking spring drives the interlocking block to move. On the one hand, the linkage inclined surface pushes the stopper to move, and the stopper drives the locking block to move, so that the locking block is completely pulled out of the locking groove. On the other hand, the interlocking block moves until the clearance groove is aligned with the operating rod. At this time, the operating rod can be pulled to insert the end of the operating rod into the clearance groove. After the operating rod moves until the linkage gear moves into the rotating groove, the locking block is pushed to insert into the connecting rod, and the stopper presses on the linkage inclined surface until the end of the locking block is inserted into the locking groove and contacts the magnet, and the interlocking block moves to reset. Through the above structure, the operation of the connecting block is simplified.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The shock-absorbing spring improves the anti-seismic performance of the distribution cabinet;

[0028] 2. Through the shock-absorbing mechanism, the power distribution cabinet of the present application can be applied to environments with different vibration intensities, thereby improving the adaptability of the power distribution cabinet of the present application;

[0029] 3. The locking mechanism limits the relative up and down movement of the cabinet and the base, making it easier for staff to inspect the cabinet or install the power distribution cabinet for this application;

[0030] 4. When the cabinet body and the base are relatively fixed by the interlocking assembly, the shock absorbing spring cannot be adjusted; when the shock absorbing spring can be adjusted by the operating lever, the cabinet body and the base cannot be locked. BRIEF DESCRIPTION OF THE DRAWINGS
