Description

An internally adjustable mounting mechanism for a low-voltage distribution cabinet Technical Field

[0001] This utility model relates to the field of low-voltage distribution cabinet technology, and in particular to an internally adjustable installation mechanism for low-voltage distribution cabinets. Background Technology

[0002] A low-voltage power distribution system consists of a distribution substation (which typically reduces the transmission voltage of the power grid to the distribution voltage), high-voltage distribution lines (i.e., voltages above 1 kV), distribution transformers, low-voltage distribution lines (voltages below 1 kV), and corresponding control and protection equipment. To improve the ease of use and safety of the low-voltage power distribution system, low-voltage switchgear is required. Low-voltage switchgear is an electrical device used in power systems, primarily for transmitting electrical energy from transformers or generators to different circuits and loads of consumers.

[0003] Existing low-voltage distribution cabinets use an internally adjustable mounting mechanism. Various electrical components are installed inside the cabinet via mounting plates. However, due to the different sizes of the electrical components, the spacing between the mounting plates is relatively small, making it difficult to flexibly adjust the spacing between the two mounting plates to facilitate the installation of electrical components. Furthermore, the electrical components are mounted on the upper and lower surfaces of the mounting plates, and since the bottom of the mounting plate is used to install the electrical components, it is not convenient to disassemble, install, replace, or maintain them, and the surface orientation of the mounting plate cannot be adjusted by flipping it.

[0004] Therefore, an internally adjustable installation mechanism for low-voltage distribution cabinets is proposed. Summary of the Invention

[0005] The purpose of this utility model is to solve the shortcomings of existing technologies where electrical components are mounted on the upper and lower surfaces of the mounting plate, and where the bottom of the mounting plate is used to mount electrical components, making it inconvenient to disassemble, install, replace, and maintain, and failing to adjust the surface orientation of the mounting plate. Therefore, this utility model proposes an internally adjustable mounting mechanism for low-voltage distribution cabinets.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] Design an internally adjustable mounting mechanism for a low-voltage distribution cabinet, including a cabinet body, an mounting plate installed inside the cabinet body, flip support mechanisms installed at both ends of the mounting plate, and a lifting adjustment mechanism provided on the outside of the flip support mechanism.

[0008] The flipping support mechanism includes a support plate and a support column. The support column is fixed to the middle of the inner side of the support plate and is rotatably inserted into the middle of both ends of the mounting plate.

[0009] The lifting adjustment mechanism includes a lifting block and a rack. The lifting block is slidably installed on the inner side of the cabinet, and the rack is vertically fixed on the inner side of the lifting block. A gear is meshing and driving between the two racks.

[0010] Furthermore, support bars are fixed on both sides of the interior of the cabinet, and the support bars have snap-fit ​​grooves inside. The lifting block is slidably snapped into the snap-fit ​​grooves. Both the snap-fit ​​grooves and the lifting block have T-shaped cross-sections, and the support bars are vertically arranged.

[0011] Furthermore, a rotating rod passes through the center of the cabinet, and a motor is installed at one end of the rotating rod. The motor is fixedly installed in the center of the outer side of the cabinet. The gear is fixedly installed at both ends of the rotating rod and is intermittently rotatably installed in the center of the snap-fit ​​groove.

[0012] Furthermore, the surface of the lifting block has a through hole located opposite the rack, and the two racks are symmetrically arranged on both sides of the gear, with their outer sides slidingly engaging with the inside of the engaging groove.

[0013] Furthermore, the mounting plate has a rotating hole in the middle, the rotating hole is horizontally set, the outer end of the support column is horizontally inserted into the rotating hole, the support plate is a rectangular plate structure, and is horizontally slidably installed at both ends of the mounting plate.

[0014] Furthermore, the mounting plate is a rectangular plate structure and is horizontally arranged. Positioning holes are opened at both ends of its side, and the positioning holes are located on both sides of the rotating hole. Guide holes are opened at both ends of the support plate. A positioning rod slides through the inside of the guide hole, and the inner end of the positioning rod is inserted into the positioning hole. The positioning rod is horizontally arranged.

[0015] Furthermore, a limiting plate is fixed to the outer end of the positioning rod, and a tension spring is sleeved on the surface of the positioning rod. The two ends of the tension spring are respectively connected between the inner side of the limiting plate and the outer side of the support plate.

[0016] Furthermore, mounting strips are evenly fixed on the upper and lower surfaces of the mounting plate, heat dissipation grooves are opened inside the mounting strips, mounting holes are evenly opened at the top of the mounting strips, the mounting holes are threaded holes, and the mounting strips are elongated and horizontally positioned.

[0017] The adjustable internal mounting mechanism for low-voltage distribution cabinets proposed in this utility model has the following advantages:

[0018] 1. This utility model provides support bars and snap-fit ​​grooves on both sides of the cabinet's interior. The mounting plate is installed between the two support bars via the support plate and lifting block, and a rack is fixed inside the lifting block. Thus, the motor drives the rotating rod and gear to rotate, and the gear meshes with the racks on both sides for transmission, driving the racks on both sides to move upward and downward respectively. This drives the two lifting blocks to move up and down along the snap-fit ​​groove, thereby flexibly adjusting the distance between the two mounting plates. This facilitates the installation of electrical components of different sizes on the surface of the mounting plate.

[0019] 2. This utility model features a mounting plate that can be flipped between two support plates via a support column. Furthermore, at both ends of the support plates, a positioning rod is connected by a tension spring. Pulling the tension spring and positioning rod outwards allows the surface of the mounting plate to be flipped around the support column, adjusting its orientation. This facilitates the disassembly, installation, replacement, and maintenance of electrical components mounted on the upper and lower sides of the mounting plate. After the mounting plate is flipped, releasing the tension spring causes it to pull the positioning rod through the guide hole and insert it into the positioning hole. This, in conjunction with the support column, mounts the mounting plate between the two support plates. The electrical components are mounted on the surface of the mounting plate via mounting strips and mounting holes, and the heat dissipation grooves accelerate the dissipation of heat generated during operation.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] For an example, please refer to Figures 1 to 5. The figures show an internally adjustable mounting mechanism for a low-voltage distribution cabinet, which includes a cabinet body 1. An mounting plate 3 is installed inside the cabinet body 1. A flip support mechanism is installed at both ends of the mounting plate 3. A lifting adjustment mechanism is provided on the outside of the flip support mechanism.

[0028] Furthermore, the lifting adjustment mechanism includes a lifting block 11 and a rack 7. The lifting block 11 is slidably installed on the inner side of the cabinet 1, and the rack 7 is vertically fixed on the inner side of the lifting block 11. A gear 8 is meshing and driving between the two racks 7.

[0029] Support bars 6 are fixed on both sides of the inside of the cabinet 1. The support bars 6 have snap-fit ​​grooves 5 inside. The lifting block 11 slides and snaps into the snap-fit ​​grooves 5. The cross-section of the snap-fit ​​grooves 5 and the lifting block 11 is T-shaped. The support bars 6 are set vertically.

[0030] A rotating rod 2 passes through the center of the cabinet 1. A motor 13 is installed at one end of the rotating rod 2. The motor 13 is fixedly installed in the center of the outer side of the cabinet 1. A gear 8 is fixedly installed at both ends of the rotating rod 2 and is intermittently installed in the center of the snap-fit ​​groove 5.

[0031] The lifting block 11 has a through hole 14 on its surface opposite the rack 7. The two racks 7 are symmetrically arranged on both sides of the gear 8, and their outer sides are slidably engaged with the inside of the engagement groove 5.

[0032] Motor 13 drives rotating rod 2 and gear 8 to rotate. Gear 8 meshes with racks 7 on both sides for transmission, driving racks 7 on both sides to move up and down respectively, thereby driving two lifting blocks 11 to move up and down along the snap-fit ​​groove 5, thus flexibly adjusting the distance between the two mounting plates 3. This makes it easy to install electrical components of different sizes on the surface of mounting plates 3.

[0033] Furthermore, the flipping support mechanism includes a support plate 10 and a support column 9. The support column 9 is fixed in the middle of the inner side of the support plate 10 and is rotatably inserted into the middle of both ends of the mounting plate 3.

[0034] The mounting plate 3 has a rotating hole 12 in the middle. The rotating hole 12 is set horizontally. The outer end of the support column 9 is inserted horizontally into the rotating hole 12. The support plate 10 is a rectangular plate structure and is horizontally slidably installed at both ends of the mounting plate 3.

[0035] At both ends of the support plate 10, a positioning rod 17 is connected by a tension spring 18. After pulling the tension spring 18 and the positioning rod 17 outward, the mounting plate 3 can be flipped with the support column 9 as the center, and the orientation of the surface of the mounting plate 3 can be adjusted, which facilitates the disassembly, installation and replacement of electrical components installed on the upper and lower sides of the mounting plate 3.

[0036] Mounting plate 3 is a rectangular plate structure and is horizontally set. Positioning holes 16 are opened at both ends of its side. Positioning holes 16 are located on both sides of rotating hole 12. Support plate 10 has guide holes 21 at both ends. Positioning rod 17 slides through the inside of guide hole 21. The inner end of positioning rod 17 is inserted into positioning hole 16. Positioning rod 17 is horizontally set.

[0037] A limiting plate 19 is fixed to the outer end of the positioning rod 17, and a tension spring 18 is sleeved on the surface of the positioning rod 17. The two ends of the tension spring 18 are respectively connected between the inner side of the limiting plate 19 and the outer side of the support plate 10.

[0038] After the mounting plate 3 is flipped over, the tension spring 18 is released. The tension spring 18 pulls the positioning rod 17 through the guide hole 21 and inserts it into the positioning hole 16. Together with the support column 9, the mounting plate 3 is installed between the two support plates 10.

[0039] Mounting strips 4 are evenly fixed on the upper and lower surfaces of mounting plate 3. Heat dissipation grooves 20 are opened inside the mounting strips 4. Mounting holes 15 are evenly opened at the top of the mounting strips 4. The mounting holes 15 are threaded holes. The mounting strips 4 are long strips and are set horizontally.

[0040] Electrical components are mounted on the surface of mounting plate 3 via mounting strip 4 and mounting holes 15, and the heat generated during use is dissipated more quickly through heat dissipation grooves 20.

[0041] Working method: By setting support bars 6 and snap-fit ​​grooves 5 on both sides of the inside of the cabinet 1, the mounting plate 3 is installed between the two support bars 6 through the support plate 10 and the lifting block 11, and the rack 7 is fixed on the inside of the lifting block 11. Therefore, the motor 13 drives the rotating rod 2 and the gear 8 to rotate. The gear 8 meshes with the rack 7 on both sides to drive the rack 7 on both sides to move up and down respectively, thereby driving the two lifting blocks 11 to move up and down along the snap-fit ​​groove 5, and thus flexibly adjusting the distance between the two mounting plates 3. In this way, it is convenient to install electrical components of different sizes on the surface of the mounting plate 3.

[0042] The mounting plate 3 can be flipped between the two support plates 10 via the support column 9. At both ends of the support plate 10, the positioning rod 17 is connected by the tension spring 18. After pulling the tension spring 18 and the positioning rod 17 outward, the mounting plate 3 can be flipped with the support column 9 as the center, and the orientation of the surface of the mounting plate 3 can be adjusted to facilitate the disassembly, installation, replacement and maintenance of electrical components installed on the upper and lower sides of the mounting plate 3. After the mounting plate 3 is flipped, the tension spring 18 is released, and the tension spring 18 pulls the positioning rod 17 through the guide hole 21 and inserts it into the positioning hole 16. Together with the support column 9, the mounting plate 3 is installed between the two support plates 10. Moreover, the electrical components are installed on the surface of the mounting plate 3 through the mounting strip 4 and the mounting hole 15, and the heat generated by the electrical components during use is dissipated more quickly through the heat dissipation groove 20.

[0043] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
