Description

Technical Field

[0001] This invention relates to the field of electrical cabinet technology, specifically to an electrical cabinet installation device. Background Technology

[0002] Electrical cabinet installation devices are widely used in industrial control, communication equipment, power systems and other fields. They are mainly used to support and install various electrical components, provide a stable installation space and protective environment for electrical components, and ensure the orderly operation and safety protection of electrical systems. They are key supporting devices in the deployment of electrical equipment.

[0003] In existing electrical cabinets, the back panel is often fixed when installing electrical components. To solve the problem of insufficient installation space, the common practice is to increase the overall size of the cabinet. However, this results in excessive cabinet space occupation, increased transportation and deployment costs, and still cannot flexibly adjust the position of the back panel, limiting the operation of installers. For the installation points of electrical components, traditional cabinet back panels often do not have a pre-set installation structure, and installation holes must be set on site by drilling. This method is not only time-consuming and reduces installation efficiency, but also easily damages the overall structural strength of the back panel, affecting the load-bearing stability of the cabinet. In terms of cable management, existing cabinets mostly rely on cable ties to bundle and organize cables. Although this can temporarily organize cables, the cable ties are inconvenient to install and remove. Adjusting cables during subsequent maintenance can easily cause secondary mess, and long-term use can lead to aging and breakage of the cable ties, resulting in tangled cables, affecting maintenance efficiency and electrical safety. Therefore, an electrical cabinet installation device is proposed. Summary of the Invention

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] This invention provides a technical solution: an electrical cabinet installation device. Please refer to [link / reference]. Figures 1-6 ,include:

[0031] Cabinet 1, with a telescopic folding bracket 6 installed at the rear end of the cabinet 1, and a back panel 7 installed at the front end of the telescopic folding bracket 6. Side blocks 10 are provided on both sides of the upper and lower ends of the back panel 7, and limit holes 12 are opened on the outer side of the side blocks 10.

[0032] Inside the cabinet 1, at the corresponding position outside the side block 10, there is a side shell 11. Inside the side shell 11, there is a side cavity 13. Inside the side cavity 13, from the inside to the outside, a first reset spring 14 and a limiting ball 15 are installed in sequence. The limiting ball 15 is adapted to the limiting hole 12.

[0033] The back plate 7 has perforations 8 evenly distributed in a rectangular array inside;

[0034] The bottom of the back plate 7 is provided with a bracket 9, and the two sides of the middle part of the bracket 9 are provided with sliders 23. The bottom of the back plate 7 is provided with sliding shells 24 on both sides outside the sliders 23, and the sliders 23 and sliding shells 24 are slidably connected.

[0035] The telescopic folding bracket 6 is fixedly connected to the rear end of the cabinet 1 and the rear end of the back panel 7 by bolts. The side block 10 is a rectangular block structure and is welded and fixed to the upper and lower ends of the back panel 7. The limiting hole 12 is a circular hole with a diameter that matches the diameter of the limiting ball 15. The inner wall of the limiting hole 12 is polished smooth to reduce friction with the limiting ball 15 and ensure that the limiting ball 15 can smoothly enter and exit the limiting hole 12 when the side block 10 moves.

[0036] The bolted connection of the telescopic folding bracket 6 ensures a firm connection with the cabinet 1 and the back panel 7, allowing for flexible stretching and folding. This enables the back panel 7 to extend out of the cabinet 1 or retract, facilitating adjustment of the back panel 7 angle by installers and improving the ease of electrical component installation. The rectangular structure of the side block 10 matches the side shell 11, ensuring that the back panel 7 does not shift when moving. The limiting hole 12 is compatible with the limiting ball 15, and combined with the elasticity of the first return spring 14, it can quickly fix the back panel 7, preventing it from shaking during installation. The smooth inner wall of the limiting hole 12 also reduces the resistance of the limiting ball 15, improving the smoothness of operation.

[0037] The side shell 11 is fixed inside the cabinet 1 at the position corresponding to the side block 10 by bolts. The side cavity 13 is a cylindrical cavity with a depth slightly greater than the sum of the natural length of the first return spring 14 and the radius of the limiting ball 15. The diameter is adapted to the outer diameter of the first return spring 14 and the diameter of the limiting ball 15. One end of the first return spring 14 is welded to the bottom of the inner wall of the side cavity 13, and the other end abuts against one side of the limiting ball 15. The limiting ball 15 is partially exposed outside the opening of the side cavity 13 so as to cooperate with the limiting hole 12.

[0038] The side shell 11 can cover both sides of the side block 10, further improving the stability of the back plate 7. The bolt fixing method facilitates the installation and maintenance of the side shell 11. The cylindrical side cavity 13 provides sufficient installation space for the first return spring 14 and the limiting ball 15, avoiding component jamming. The welding and contact connection of the first return spring 14 can realize automatic reset, and the back plate 7 can be fixed and unlocked without additional tools, simplifying the operation steps. The limiting ball 15 is partially exposed in the side cavity 13, ensuring that it can quickly cooperate with the limiting hole 12, ensuring that the back plate 7 can be stably fixed in any adjustment position, improving installation efficiency.

[0039] Please see Figure 2 , Figure 3 and Figure 4 The perforation 8 is integrally formed with the back plate 7, the slider 23 is fixedly connected with the bracket 9, and the sliding shell 24 is fixedly connected with the back plate 7; the perforation 8 facilitates the installation of electrical components.

[0040] The perforation 8 is a circular hole with a diameter that is compatible with the diameter of common electrical component mounting bolts on the market. The spacing between adjacent perforations 8 is equal and meets the standard spacing requirements for electrical component installation. The inner wall of the perforation 8 is tapped with internal threads to fix the electrical component with bolts, and the edges of the perforation 8 are polished smooth to prevent the installer's hands from being cut.

[0041] The circular perforations 8 are compatible with most standard mounting bolts, improving the device's versatility. Different electrical components can be installed without additional drilling, saving operation time. The evenly spaced perforations 8 meet the installation requirements of electrical components of different sizes, making them more adaptable. The internal threads allow electrical components to be directly fixed with bolts, ensuring a firm connection that is not easy to loosen and preventing the electrical components from shifting during cabinet operation. The smooth edges of the perforations 8 prevent scratches to the hands of installers, ensuring operational safety. The reserved wiring space also allows for neater internal wiring in the cabinet, facilitating subsequent maintenance.

[0042] The bracket 9 is a metal bracket with a rust-proof surface to extend its service life; the slider 23 and the bracket 9 are integrally formed on both sides of the middle part; the sliding shell 24 has a groove inside, the size of which is adapted to the slider 23; the sliding shell 24 is fixed to the bottom of the back plate 7 at the outer position corresponding to the slider 23 by welding.

[0043] The rust-proof treatment of the metal bracket 9 allows it to be used for a long time even in humid environments within the cabinet. It can stably support the wires and prevent them from dangling tangledly. The grooves of the slider 23 and the sliding shell 24 ensure that the bracket 9 does not shift or fall off when it is moved horizontally. The smooth sliding facilitates the quick installation and removal of the bracket 9. The overall structure can effectively organize the wires, reduce the risk of wire tangling, improve the cleanliness of the cabinet interior, and facilitate future cable maintenance.

[0044] Please see Figure 4 and Figure 5 The bracket 9 has an inner cavity 17 in the middle. The inner cavity 17 is equipped with a plug rod 18. The plug rod 18 is located inside the inner cavity 17 and is equipped with a second return spring 20 and a baffle 19 from the outside to the inside.

[0045] Please see Figure 4 and Figure 5 The bottom of the back plate 7 is provided with a slot 22, and the insertion rod 18 is adapted to the slot 22. The baffle 19 is fixedly connected to the insertion rod 18. A pull plate 21 is provided on the outside of the bracket 9 of the insertion rod 18, and the pull plate 21 is fixedly connected to the insertion rod 18.

[0046] Pull plate 21 facilitates the pulling of insert rod 18, thereby causing insert rod 18 to be pulled out of slot 22.

[0047] Please see Figure 4 and Figure 5 Anti-slip pads 16 are provided on both sides of the upper part of the bracket 9, and the anti-slip pads 16 are glued to the bracket 9.

[0048] The anti-slip mat 16 is made of rubber and has good elasticity and anti-slip performance. The anti-slip mat 16 is rectangular and its size is adapted to the area of ​​the upper two sides inside the bracket 9, so that it can completely fit the inner wall of the bracket 9. The anti-slip mat 16 is bonded to the bracket 9 with high temperature and aging resistant industrial adhesive, and the surface is provided with raised grid pattern.

[0049] The rubber anti-slip pad 16 has good elasticity and can closely adhere to the surface of the wire, increasing the friction between the wire and the bracket 9 and preventing the wire from slipping. At the same time, the rubber material can also reduce the direct friction between the wire and the metal bracket 9, protecting the wire insulation layer from being scratched and extending the service life of the wire. The high temperature and aging resistant adhesive ensures that the anti-slip pad 16 will not fall off in the long-term high temperature operation environment of the cabinet, improving durability. The raised grid pattern on the surface further enhances the anti-slip effect. Even if the cabinet is subjected to slight vibration, the wire can be stably fixed in the bracket 9, avoiding poor wire contact and improving the operational safety of the cabinet.

[0050] Please see Figure 1 The cabinet body 1 has a cabinet door 2 installed at the front end, and the cabinet door 2 is rotatably connected to the cabinet body 1; the cabinet door 2 has windows 3 on both the top and bottom sides at the front end, and the windows 3 are fixedly connected to the cabinet door 2; the cabinet door 2 has a handle 4 installed in the middle of the front end, and the handle 4 is connected to the cabinet door 2; the cabinet body 1 has feet 5 at the four corners at the bottom, and the feet 5 are fixedly connected to the cabinet body 1.

[0051] Cabinet door 2 is connected to the front side of cabinet body 1 by hinges and is made of cold-rolled steel plate with a spray coating to prevent rust. Window 3 is made of tempered glass and is fixed to cabinet door 2 by sealing strip. Handle 4 is made of plastic and is fixed to the middle of the front of cabinet door 2 by bolts, with a non-slip surface. Foot 5 is a rubber-wrapped metal core structure and is fixed to the four bottom corners of cabinet body 1 by bolts.

[0052] The hinged cabinet door 2 opens and closes smoothly. The cold-rolled steel plate material and spray coating treatment make it strong and rust-resistant, effectively protecting the internal electrical components from external dust and impacts. The tempered glass window 3 has good light transmission, allowing observation of the internal electrical components' operating status without opening the cabinet door 2, reducing dust entry. The sealing strip further enhances the dustproof effect. The non-slip handle 4 makes it easy to open the cabinet door 2. The plastic material is lightweight and has a good feel, and the bolt fixation ensures that it will not easily fall off. The rubber-coated metal core feet 5 can buffer the vibration of the cabinet operation, reduce the impact on the internal electrical components, and increase the friction with the ground to prevent the cabinet from shifting and improve the overall stability.

[0053] This solution: Hold handle 4 to open cabinet door 2. When electrical components need to be installed, pull back panel 7. Side blocks 10 on both sides of back panel 7 collide and squeeze with limiting ball 15, causing limiting ball 15 to move toward side cavity 13 and squeeze first return spring 14. As back panel 7 moves, limiting ball 15 disengages from side block 10, and telescopic folding bracket 6 is stretched, so that back panel 7 can extend out of cabinet 1 and turn to adjust the angle, thereby facilitating the installation of electrical components outside back panel 7.

[0054] Pulling the pull plate 21 causes the insertion rod 18 to disengage from the slot 22. Then, the bracket 9 is moved outward, causing the slider 23 to disengage from the sliding shell 24. After the wire is combed, it is bent backward from the lower front side of the back plate 7 and then inserted. The bracket 9 holds the wire and the pull plate 21 is pulled to retract the insertion rod 18 into the inner cavity 17. Then, the slider 23 is slidably connected to the sliding shell 24. Then, the pull plate 21 is released, and the second return spring 20 returns to its original position and pushes the stop plate 19 to insert the insertion rod 18 into the slot 22, completing the installation of the bracket 9.

[0055] The reset back plate 7 causes the telescopic folding bracket 6 to fold, and the limiting ball 15 engages with the limiting hole 12 of the side block 10 to complete the storage and fixation of the back plate 7.
