Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinets, and in particular to a multifunctional mounting base for a power distribution cabinet. Background Art

[0002] During the construction process, a large number of distribution cabinets of different specifications are needed for power distribution, such as first-level distribution cabinets, second-level distribution cabinets and third-level distribution cabinets. According to regulatory requirements, these distribution cabinets need to be installed overhead at the construction site during use. The existing overhead method is generally for workers to install them through welded steel structure brackets. During use, people often collide with the distribution cabinet or its overhead installation bracket when carrying poles and building materials. The overhead bracket cannot provide effective buffering, resulting in the distribution cabinet overturning or the welded bracket breaking, and it is not convenient to transfer. At the same time, some steel plates will be laid when the construction site is soft. When the overhead bracket is placed on the steel plate, vehicles or people stepping on the steel plate will cause the distribution cabinet to vibrate. Long-term vibration will cause the distribution cabinet wiring to wear and the frame to deform, posing a safety hazard.

[0003] In view of the above problems, the present invention proposes a multifunctional mounting base for a power distribution cabinet. Summary of the Invention

[0004] In response to the problems in the above technical background, the purpose of the present invention is to provide a multifunctional mounting base for a distribution cabinet, which solves the problem mentioned in the background technology that the existing distribution cabinets installed overhead at the construction site are prone to overturning or welded bracket breakage. At the same time, when the overhead bracket is placed on a steel plate, the passage of people or vehicles will cause vibration, resulting in wiring wear and frame deformation.

DETAILED DESCRIPTION

[0030] The following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0031] like Figure 1-9 As shown, a multifunctional mounting base for a power distribution cabinet includes a frame 200. The frame 200 can be made of stainless steel and can effectively prevent rain erosion when used outdoors. Sliding clamps 300 that can elastically slide to both sides are symmetrically mounted on the frame 200. The bottom of the power distribution cabinet 100 is mounted on the two sliding clamps 300. The symmetrical elastic sliding mounting of the sliding clamps 300 can, on the one hand, meet the installation requirements of various types of power distribution cabinets 100, and on the other hand, can cushion the vibration caused by external forces on the power distribution cabinet 100.

[0032] The frame 200 is symmetrically installed with a shock-absorbing telescopic support mechanism 400 on both sides in the horizontal direction. The shock-absorbing telescopic support mechanism 400 includes a two-way telescopic adjustment unit for adjusting the support angle and height. The support angle and height of the shock-absorbing telescopic support mechanism 400 are controlled by adjusting the two-way telescopic adjustment unit, and can be adjusted according to the usage scenario. The operation is convenient. The outer end of the first threaded rod 410 included in the two-way telescopic adjustment unit is rotatably installed in the middle of the adjacent side sliding clamp 300. When the distribution cabinet 100 deviates to one side, the two-way telescopic adjustment unit is driven by the sliding clamp 300 to control the shock-absorbing telescopic support mechanism 400 to increase the support angle to prevent overturning, thereby increasing the overall impact resistance of the installed distribution cabinet 100; the frame 200 is symmetrically rotated to install the telescopic support mechanism 500 in the longitudinal direction. The telescopic support mechanism 500 is installed with a rubber pad 530 on the top while supporting. Through front and rear clamping and squeezing, it can buffer longitudinal vibrations. The telescopic support mechanism 500 is used to auxiliary support the frame 200, further increasing the safety and stability of the support.

[0033] Working Principle: By providing a sliding clamp 300 that can slide elastically in both directions to clamp and install the base of the distribution cabinet 100, it can not only meet the installation requirements of various models of distribution cabinets 100, but also cushion the vibration caused by external forces on the distribution cabinet 100. When the distribution cabinet 100 deviates to one side, the sliding clamp 300 pushes the shock-absorbing telescopic support mechanism 400 on the side of the deviation direction to extend and simultaneously reduce vibration. This design increases the impact resistance of the distribution cabinet installation, preventing deflection or overturning after impact. At the same time, the support height and angle of the shock-absorbing telescopic support mechanism can be adjusted through the two-way telescopic adjustment unit, improving the stability of the installation support. The longitudinally arranged telescopic support mechanism then provides auxiliary support adjustment, further enhancing the stability of the installation support.

[0034] like Figure 3 、 4 As shown, the two side plates of the frame 200 are laterally symmetrically provided with sliding rail grooves 210 with openings facing each other, and fixing rods 330 are fixedly installed in the sliding rail grooves 210. Plugs 310 are symmetrically provided at both ends of the sliding clamp seat 300 and inserted into the sliding rail grooves 210, which increases the stability of sliding. At the same time, the fixing rods 330 pass through the plugs 310, and shock-absorbing springs 340 are symmetrically installed on the fixing rods 330 on the outer sides of the plugs 310 on both sides. The tops of the two sliding clamp seats 300 are symmetrically provided with angular clamp grooves 320 with openings facing each other for installing the bottom of the distribution cabinet 100. The symmetrical sliding installation of the sliding clamp seat 300 can adapt to the installation and positioning of distribution cabinets 100 of various sizes on the one hand, and on the other hand, this buffering design can effectively buffer the horizontal vibration of the distribution cabinet 100, thereby increasing the seismic performance of the overhead installed distribution cabinet 100.

[0035] like Figure 4 、7 As shown, the frame 200 is symmetrically provided with first leg grooves 220 on both sides in the horizontal direction, and the top end of the rotating plate 460 included in the shock-absorbing telescopic support mechanism 400 is rotatably installed in the first leg groove 220. The frame 200 is symmetrically provided with second leg grooves 230 on both sides in the longitudinal direction, and the top end of the deflection plate 510 included in the telescopic support mechanism 500 is rotatably installed in the second leg groove 230. By setting the first leg groove 220 and the second leg groove 230 to install the shock-absorbing telescopic support mechanism 400 and the telescopic support mechanism 500, stable support adjustment is achieved, and they can be rotated and stored in the frame 200 when retracted or extended, thereby reducing temporary space.

[0036] like Figure 5 As shown, the shock-absorbing telescopic support mechanism 400 also includes a plurality of support rods 470. Generally, two support rods 470 are provided. A plurality of telescopic holes are provided in parallel on the rotating plate 460. The telescopic holes include a first telescopic hole 461 with a large inner diameter and a second telescopic hole 463 with a small outer diameter. One side of the first telescopic hole 461 is connected to a first through groove 462 that penetrates one side of the rotating plate 460. The plurality of support rods 470 are inserted into the second telescopic hole 463 and the first telescopic hole 461. At the same time, an anti-slip block 480 is provided on the inner end of the support rod 470. The diameter of the anti-slip block 480 is the same as that of the first telescopic hole 461. 1 has the same diameter, which increases the stability of sliding. At the same time, the diameter of the support rod 470 is equal to the diameter of the second telescopic hole 463. One side of the anti-slip block 480 is connected to an insert block 481 that penetrates the first through groove 462. The outer ends of the multiple insert blocks 481 are rotatably connected to the two-way telescopic adjustment unit. The two-way telescopic adjustment unit realizes the function of controlling the extension and contraction of the multiple support rods 470 by pushing the multiple insert blocks 481 to slide. The bottom ends of the multiple support rods 470 are connected to a walking unit that can switch between support and walking modes, so as to achieve stable support while also meeting the convenience of movement during movement.

[0037] like Figure 5 、 6 As shown, the walking unit includes a rotating frame 490, and a support column 491 is rotatably installed in the rotating frame 490. The axial cut of the side wall of the support column 491 has a support surface 492. Anti-slip strips or anti-slip grooves can be provided on the support surface 492 as needed. The support column 491 is provided with a cylindrical protective shell 494 with sealing plates at both ends. The protective shell 494 has a fan-shaped opening 495, and an anti-rotation bolt 496 is installed at the end of the protective shell 494. When supporting, the fan-shaped opening 495 coincides with the support surface 492. When walking, the support surface 492 rotates into the inside of the protective shell 494 and is fixed by the anti-rotation bolt 496. This enclosing structural design is convenient for switching between support and rotation modes on the one hand, and can avoid the occurrence of rotation limit during movement on the other hand.

[0038] like Figure 5As shown, the two-way telescopic adjustment unit includes a first threaded rod 410 and a second threaded rod 430 with opposite threads. The inner ends of the first threaded rod 410 and the second threaded rod 430 are threadedly installed on both sides of the two-way internal threaded cylinder 420, and the outer ends of the second threaded rod 430 are fixedly connected to the push-pull plate 440. One side of the push-pull plate 440 is installed with multiple rotating seats 450, and the outer ends of the insert blocks 481 are rotatably installed on the rotating seat 450. The outer ends of the first threaded rod 410 are rotatably installed in the rotating groove 301 provided in the lower middle part of the sliding clamp seat 300. When it is necessary to control the support angle and support height of the multiple support rods 470, the two-way internal threaded cylinder 420 is rotated to control the first threaded rod 410 and the second threaded rod 430 to move toward both ends. The second threaded rod 430 drives the rotating seat 450 to push the multiple insert blocks 481 to move through the push-pull plate 440, thereby realizing the function of controlling the extension length of the multiple support rods 470, and can also control the rotation angle of the rotating plate 460.

[0039] like Figure 7-9 As shown, the telescopic support mechanism 500 includes a deflection plate 510 rotatably installed in the second leg groove 230, and a telescopic groove 511 is provided in the deflection plate 510 that passes through the bottom end. At the same time, the telescopic groove 511 is connected to the second through groove 512 that passes through the outer side surface of the deflection plate 510, and anti-slip teeth 513 are symmetrically provided on the inner side surfaces of the telescopic groove 511 on both sides of the second through groove 512. A support plate 540 is slidably installed in the telescopic groove 511, and an elastic self-locking part for controlling its telescopic extension is installed on the support plate 540. The telescopic extension of the support plate 540 is unlocked by pressing the elastic self-locking part, thereby controlling the auxiliary support height in turn, thereby further increasing the stability of the installation.

[0040] like Figure 7-9 As shown, a contraction groove 541 is horizontally provided on the support plate 540, and the middle part of the contraction groove 541 is connected to the concave contraction hole 542. The elastic self-locking member includes a telescopic column 550, and the bottom end of the telescopic column 550 is inserted into the contraction hole 542. At the same time, a return spring 570 is installed in the contraction hole 542 at the bottom end of the telescopic column 550. The telescopic column 550 is symmetrically connected with teeth 560 on both sides. When locked, the teeth 560 on both sides are inserted into the anti-slip teeth 513 on both sides for locking. The top end of the telescopic column 550 passes through the second through-groove 512 and is connected to a pushing block 580. When unlocked, the pushing block 580 is pressed to push the telescopic column 550 to contract, and the telescopic column 550 drives the teeth 560 on both sides to disengage from the anti-slip teeth 513 on both sides.

[0041] The telescopic column 550 is retracted by pressing the push block 580. The telescopic column 550 squeezes the return spring 570 and drives the inserting teeth 560 on both sides to disengage from the anti-slip teeth 513 on both sides, thereby realizing the unlocking function. After the adjustment is completed, the pressing force is removed. Driven by the return spring 570, the telescopic column 550 moves axially outward, driving the inserting teeth 560 on both sides to insert into the anti-slip teeth 513 on both sides, thereby realizing the sliding lock.

[0042] An extrusion block 520 is connected to the top of the deflection plate 510, and a rubber pad 530 is installed on one side of the extrusion block 520. The inner side of the rubber pad 530 is in contact with the bottom side of the distribution cabinet 100. By installing the rubber pad 530, longitudinal vibration can be absorbed and the transmission between the mounting base and the distribution cabinet 100 can be reduced when the distribution cabinet 100 is subjected to external force or the mounting base itself is subjected to vibration.

[0043] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and modifications are intended to fall within the scope of the present invention.
