Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet technology, and more specifically to an adjustable mounting bracket for power distribution cabinets. Background Technology

[0002] Distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), and are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are few circuits; motor control centers are used in situations where the load is concentrated and there are many circuits. They distribute the electrical energy from a circuit of the upstream power distribution equipment to the nearest load.

[0003] This mainly includes, but is not limited to, the cabinet located at the top of the enclosure, protective grounding devices, main circuit fuse groups, branch circuit breaker groups, and other circuit components installed on the mounting rack inside the enclosure. During assembly, the installation positions of these components may be adjusted according to site conditions. The existing adjustment method mainly involves adjusting the fixed height of the mounting rack, which is fixed to the internal support frame with bolts. This adjustment method involves constantly connecting and disconnecting the assembly bolts, which is time-consuming. Furthermore, the height adjustment is limited to the height corresponding to the reserved bolt holes, making it restrictive and inflexible. At the same time, the existing mounting rack cannot be adjusted in the longitudinal depth, making it difficult to meet the needs of various installation scenarios.

[0004] To address the aforementioned issues, this invention proposes an adjustable mounting bracket for use in power distribution cabinets. Summary of the Invention

[0005] To address the problems mentioned above in the technical background, the purpose of this invention is to provide an adjustable mounting bracket for power distribution cabinets, which solves the problems of cumbersome and inflexible positioning and adjustment of existing equipment mounting brackets in power distribution cabinets mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] An adjustable mounting bracket for a power distribution cabinet includes a support frame installed inside the power distribution cabinet. A U-shaped guide rail frame with an upward opening is slidably mounted longitudinally on the support frame. A mounting plate is slidably mounted on the guide rail frame. Multiple sets of support slides are parallelly mounted on the back side of the mounting plate. A multi-directional adjustment control component is slidably mounted on the support frame behind the mounting plate. The multi-directional adjustment control component includes a lifting part and rotating parts symmetrically rotated on both sides of the lifting part. The outer ends of the rotating parts are inserted into the support slides.

[0008] The bottom of the guide rail is equipped with a support member that controls the sliding and fine adjustment of the mounting plate relative to the outer end of the rotating part. This support member is also used to share the load of the mounting plate. After the mounting plate slides upward for fine adjustment, the outer end of the rotating part slides and unlocks in the support slide. During the process of the mounting plate sliding outward, the outer ends of the rotating parts on both sides slide in opposite directions in the support slide.

[0009] Furthermore, the support frame includes four vertical rods symmetrically installed at the four corners inside the distribution cabinet. Horizontal braces are symmetrically installed at the upper and lower ends of the vertical rods on both sides and between the vertical rods at the rear. Multiple sliding clamping parts are symmetrically provided on both sides of the guide rail frame. The sliding clamping parts are slidably clamped onto the horizontal braces. Rotating grooves with openings facing each other are symmetrically provided on the rear vertical rods. A fixed rotating shaft is installed in the rotating groove. The second sleeve included in the inner end of the rotating part is rotatably and axially slidingly installed on the fixed rotating shaft. Positioning plates are installed above the two rear vertical rods. The threaded rod included in the lifting part passes through the middle of the positioning plate.

[0010] Furthermore, the sliding clamping member includes two clamping seats symmetrically mounted on one side of the guide rail frame. Multiple clamping rollers with axially perpendicular sides of the guide rail frame are symmetrically mounted on the two clamping seats facing each other. The multiple clamping rollers arranged vertically are respectively clamped on the upper and lower surfaces of the cross brace.

[0011] Furthermore, the two side plates of the guide rail frame are symmetrically provided with protrusions facing inward. The mounting plates are slidably mounted on the protrusions on both sides by symmetrically recessed vertical grooves. Support members are installed on the bottom plate of the guide rail frame. The support members are support adjustment bolts. The top of the support adjustment bolts is installed through the middle of the bottom plate of the guide rail frame. The support adjustment bolts and the guide rail frame are installed in a threaded engagement manner. At the same time, the top of the support adjustment bolts is connected to a support plate.

[0012] Furthermore, multiple support slides are installed parallel to each other on the rear side of the mounting plate. Each support slide includes two parallel support slides, with a transverse sliding groove between the two support slides and openings facing each other. Anti-slip teeth are installed in the upper transverse sliding groove. The outer end of the rotating plate included in the rotating part is inserted between the two support slides, and the outer end of the rotating plate passes through a limiting shaft. A toothed block is installed on the top of the limiting shaft. Before the mounting plate slides horizontally, the mounting plate is lifted by the support adjusting bolts, and the mounting plate drives the support slides and the upper anti-slip teeth to disengage from the toothed block.

[0013] Furthermore, the bottom of the toothed block is rotatably mounted on the top of the limiting shaft through a shaft hole, and the top of the toothed block is provided with a lower anti-slip tooth that engages with the upper anti-slip tooth.

[0014] Furthermore, the rotating part also includes a second sleeve that penetrates the inner ends of multiple rotating plates. The top end of the second sleeve is provided with an upper anti-detachment ring. The lifting plate included in the lifting part is symmetrically connected to the two ends of the first sleeve. The bottom inner side of the first sleeve is provided with a lower anti-detachment ring. The top ends of the second sleeves included in the rotating part on both sides are respectively inserted into the first sleeves on both sides. At the same time, the upper anti-detachment ring and the lower anti-detachment ring are rotatably fastened together.

[0015] Furthermore, the lifting part also includes a threaded rod installed in the middle of the lifting plate, the threaded rod being installed through the middle of the positioning plate, and bolts for fastening the lifting are installed on the threaded rod above the positioning plate.

[0016] Furthermore, the mounting plate is uniformly provided with a plurality of threaded holes for mounting components.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] In this invention, an upward-opening guide rail frame is longitudinally slidably installed on a support frame. The guide rail frame is U-shaped, and a mounting plate is slidably installed on the guide rail frame. Multiple sets of support slides are parallelly installed on the back side of the mounting plate. A multi-directional adjustment control component is slidably installed on the support frame behind the mounting plate. The multi-directional adjustment control component includes a lifting part and rotating parts symmetrically rotated on both sides of the lifting part. The outer ends of the rotating parts are inserted into the support slides. A support component is installed at the bottom of the guide rail frame to control the vertical sliding adjustment of the mounting plate relative to the outer ends of the rotating parts. This support component also serves to share the load of the mounting plate. After the mounting plate slides upward for slight adjustment, the outer ends of the rotating parts slide unlock within the support slides. During the outward sliding of the mounting plate, the outer ends of the rotating parts on both sides are supported. The mounting bracket slides in reverse. When adjusting the vertical height of the mounting plate, the lifting part controls the up-and-down movement of the rotating part. The rotating part drives the mounting plate to slide up and down on the guide rail and position itself. When adjusting horizontally, the support member lifts the mounting plate, allowing the outer end of the rotating part to slide and unlock within the support bracket. After adjustment, the support member lowers, locking the outer end of the rotating part within the support bracket. The support member and the multi-directional adjustment control member jointly bear the load of the mounting plate. The load distribution is adjusted by the support height of the support member, and the guide rail mainly provides gravity support, ensuring installation stability while fulfilling the multi-directional adjustment function. It is applicable to many scenarios and is easy to install. Attached Figure Description

[0032] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0033] like Figure 1-11 As shown, an adjustable mounting bracket for a power distribution cabinet includes a support frame 200 installed inside the power distribution cabinet 100. A guide rail 300 with an upward opening is longitudinally slidably mounted on the support frame 200. The guide rail 300 is made of stainless steel and is U-shaped. A mounting plate 400 is slidably mounted on the guide rail 300. The mounting plate 400 has multiple threaded holes evenly provided for mounting components. The components are positioned and mounted on the mounting plate 400 by bolts or screws. Multiple sets of support slides 410 are parallelly mounted on the back side of the mounting plate 400. A multi-directional adjustment control component 500 is slidably mounted on the support frame 200 behind the mounting plate 400. The multi-directional adjustment control component 500 includes a lifting part and rotating parts symmetrically rotated on both sides of the lifting part. The outer end of the rotating part is inserted into the support slide 410.

[0034] The bottom of the guide rail frame 300 is equipped with a support member that allows the mounting plate 400 to slide up and down relative to the outer end of the rotating part for fine adjustment. The support member lifts the mounting plate 400, allowing the outer end of the rotating part to slide and unlock within the support slide 410. After adjustment, the support member is lowered, locking the outer end of the rotating part within the support slide 410. The load of the mounting plate 400 is shared by the support member and the multi-directional adjustment control member 500. The gravity support can be redistributed by adjusting the support height of the support member. Ultimately, the guide rail frame 300 provides the main gravity support, ensuring installation stability while fulfilling the multi-directional adjustment function.

[0035] like Figure 2-6 As shown, the support frame 200 includes four vertical rods 210 symmetrically installed at the four corners inside the distribution cabinet 100. Horizontal braces 220 are symmetrically installed at the upper and lower ends of the vertical rods 210 on both sides and at the rear. The two ends of the horizontal braces 220 are fixed to the vertical rods 210 with bolts. Multiple sliding clamps 320 are symmetrically provided on both sides of the guide rail frame 300. The sliding clamps 320 are slidably engaged with the horizontal braces 220, facilitating the sliding of the guide rail frame 300. The adjustment is achieved by symmetrically providing opposing rotating grooves 211 on the rear vertical rod 210 and installing a fixed rotating shaft 212 within the rotating grooves 211, which saves space occupied by the outer installation, increases the rotation radius of the rotating part, and increases the extension range. The second sleeve 530 included in the inner end of the rotating part is rotatably and axially slidably mounted on the fixed rotating shaft 212. A positioning plate 230 is installed above the two rear vertical rods 210, and the threaded rod 560 included in the lifting part passes through the middle of the positioning plate 230.

[0036] like Figure 2 , 6As shown in Figure 7, the sliding clamping member 320 includes two clamping seats 321 symmetrically installed on one side of the guide rail frame 300. The clamping seats 321 are welded to the side of the guide rail frame 300. Multiple clamping rollers 322 with axial direction perpendicular to the side of the guide rail frame 300 are symmetrically installed on the two clamping seats 321 facing each other. The multiple clamping rollers 322 arranged vertically are clamped on the upper and lower surfaces of the cross brace 220 respectively. By setting the clamping rollers 322, it is convenient to slide and adjust, and also provides a good support effect.

[0037] like Figure 6 , 9 As shown, the guide rail frame 300 has symmetrical protrusions 301 on both sides of the frame plates facing inward. The mounting plate 400 is slidably mounted on the protrusions 301 on both sides by symmetrically recessed vertical sliding grooves 401. The protrusions 301 and vertical sliding grooves 401 increase the stability of sliding. A support component is installed on the bottom plate of the guide rail frame 300. The support component is a support adjusting bolt 310. The top of the support adjusting bolt 310 is installed through the middle of the bottom plate of the guide rail frame 300. The support adjusting bolt 310 and the guide rail frame 300 are installed by threaded engagement. At the same time, the top of the support adjusting bolt 310 is connected to a support plate 311. The support plate 311 increases the stability of the support.

[0038] like Figure 9 , 10 As shown, multiple support slides 410 are installed in parallel on the rear side of the mounting plate 400. Each support slide 410 includes two parallel support slides. A transverse slide groove 411 with openings facing each other is provided between the two support slides. An anti-slip tooth 412 is installed in the upper transverse slide groove 411. The outer end of the rotating plate 540 included in the rotating part is inserted between the two support slides. At the same time, the outer end of the rotating plate 540 is installed through a limiting shaft 541. A toothed block 550 is installed on the top of the limiting shaft 541. Before the mounting plate 400 slides horizontally, the mounting plate 400 is lifted by the support adjusting bolt 310. The mounting plate 400 drives the support slides 410 and the upper anti-slip tooth 412 to disengage from the toothed block 550. After the horizontal position is adjusted, the support adjusting bolt 310 is rotated and lowered. The mounting plate 400 drives the support slides 410 and the upper anti-slip tooth 412 to lower. The upper anti-slip tooth 412 locks with the toothed block 550.

[0039] like Figure 10As shown, the bottom of the toothed block 550 is rotatably mounted on the top of the limiting shaft 541 through a shaft hole 551. The shaft hole 551 is fitted onto the limiting shaft 541 to prevent the rotation of the rotating plate 540 from being limited. The top of the toothed block 550 is provided with a lower anti-slip tooth 552 that locks with the upper anti-slip tooth 412. During horizontal adjustment, the support slide 410 moves upward relative to the rotating plate 540. At this time, the bottom end of the limiting shaft 541 is always inserted into the lower transverse slide groove 411 to prevent it from falling out. After the upper anti-slip tooth 412 disengages from the lower anti-slip tooth 552, during horizontal adjustment, the outer end of the rotating plate 540 drives the toothed block 550 to slide in the transverse slide groove 411. After adjustment, it is reset and locked.

[0040] like Figure 11 As shown, the rotating part also includes a second sleeve 530 that passes through the inner end of multiple rotating plates 540. The top of the second sleeve 530 is provided with an upper anti-detachment ring 531. The lifting plate 510 included in the lifting part is symmetrically connected to the two ends of the first sleeve 520. The bottom inner side of the first sleeve 520 is provided with a lower anti-detachment ring 521. The tops of the second sleeves 530 included in the rotating parts on both sides are respectively inserted into the first sleeves 520 on both sides. At the same time, the upper anti-detachment ring 531 and the lower anti-detachment ring 521 are rotatably fastened. This structural design satisfies the rotatable connection while being installed on the fixed rotating shaft 212, increasing the stability of the sliding control.

[0041] like Figure 2-5 As shown in Figure 9, the lifting unit also includes a threaded rod 560 installed in the middle of the lifting plate 510. The threaded rod 560 is installed through the middle of the positioning plate 230. At the same time, a bolt 561 for fastening the lifting is installed on the threaded rod 560 above the positioning plate 230. The lifting of the threaded rod 560 is controlled by rotating the bolt 561. The threaded rod 560 drives the lifting plate 510 to rise and fall, thereby completing the function of vertical height adjustment and control.

[0042] The foregoing has shown and described 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 embodiments and descriptions in the specification are merely principles of the invention.
