Abstract
Description
Technical Field
[0001] This utility model relates to the field of control cabinet technology, specifically to a low-voltage control cabinet for a building. Background Technology
[0002] In modern buildings, low-voltage electrical layout is a crucial aspect, involving the wiring and installation of various intelligent systems. Low-voltage systems mainly include telephone, network, monitoring, broadcasting, and building automation systems. A well-planned layout of these systems ensures efficient operation of communication, security, and intelligent management within the building. Control cabinets, which centrally house various electronic components, are one of the key pieces of equipment in low-voltage system layout. These control cabinets not only provide a centralized installation platform for various electronic devices but also effectively manage and maintain them. By centralizing various electronic components within the control cabinet, system wiring and connections are greatly simplified, improving system stability and reliability. Most existing control cabinets have simple structures, and those used in low-voltage systems often rely on a few ventilation holes for single-mode heat dissipation. Therefore, if too many electronic components are installed inside the control cabinet, it becomes difficult to maintain the operating temperature of these components, easily leading to overheating and affecting data transmission. To address this, we propose a new low-voltage control cabinet for buildings. Utility Model Content
[0003] The purpose of this utility model is to provide a low-voltage control cabinet for buildings to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a low-voltage control cabinet for a building, comprising a cabinet body, a cabinet door hinged to the front side wall of the cabinet body, an assembly cavity and a connection cavity formed in the inner cavity of the cabinet body, a heat dissipation groove formed in the side wall of the cabinet body, and snap-fit holes evenly formed in the inner side wall of the assembly cavity, the snap-fit holes, the connection cavity and the heat dissipation groove being connected, a partition plate being assembled in the assembly cavity, and a snap-fit mechanism being assembled between the two ends of the partition plate and the snap-fit holes.
[0005] Preferably, the snap-fit mechanism includes an installation cavity, which is opened inside a partition. The top of the installation cavity has a sliding groove that penetrates the partition. A snap-fit frame is slidably connected inside the installation cavity. A handle block that penetrates the sliding groove is fixedly connected to the top of the snap-fit frame. A telescopic shaft is fixedly assembled between one side wall of the snap-fit frame and the installation cavity. A spring is sleeved on the outer side wall of the telescopic shaft. A snap-fit block that penetrates the partition is fixedly connected to the other side wall of the snap-fit frame.
[0006] Preferably, a guide shaft that passes through the snap-fit bracket is fixedly assembled inside the sliding groove.
[0007] Preferably, the sidewalls of the partition are uniformly provided with cable management grooves.
[0008] Preferably, a dustproof mesh is embedded in the heat dissipation groove.
[0009] Compared with existing technologies, the beneficial effects of this utility model are as follows: A low-voltage control cabinet for buildings adopts a connected layout of assembly cavity, connecting cavity, and heat dissipation slot in its overall structural design. In this design, multiple snap-fit holes are evenly opened on the side wall of the assembly cavity. These snap-fit holes not only have the function of fixing and adjusting the position of the partition, but also can cooperate with the connecting cavity and heat dissipation slot even when the partition is not installed, thereby effectively promoting air circulation between the external environment and the assembly cavity. This design not only improves the heat dissipation efficiency of the low-voltage control cabinet, but also enhances its overall assembly flexibility and adaptability. At the same time, the partition is connected and fixed to the snap-fit holes through the snap-fit mechanism installed inside its end. This snap-fit mechanism design makes the process of fixing and adjusting the position of the partition simpler and more convenient. In this way, when laying the low-voltage system, users can easily adjust the position of the partition, thereby ensuring a more reasonable and orderly overall layout of the low-voltage system.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0016] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4This utility model provides a technical solution: a low-voltage control cabinet for a building, including a cabinet body 1, a cabinet door 2 hinged to the front side wall of the cabinet body 1, the cabinet door 2 is used to close the cabinet body 1, and an observation window 3 is embedded in the cabinet door 2. The observation window 3 is made of explosion-proof glass. By setting the observation window 3, it is convenient to observe the operating status of each wiring switch installed in the cabinet door 2.
[0017] The cabinet 1 has an assembly cavity 4 and a connection cavity 5. The assembly cavity 4 is used for assembling various wiring switches. The side wall of the assembly cavity 4 has evenly spaced snap-fit holes 6, which are connected to the connection cavity 5. The side wall of the cabinet 1 has a heat dissipation groove 7. The assembly cavity 4 is equipped with a partition 8. The two ends of the partition 8 are embedded with snap-fit mechanisms 9. Through the cooperation of the snap-fit mechanism 9 and the snap-fit hole 6, the partition 8 can be snapped and fixed to different positions in the assembly cavity 4. Thus, according to the actual needs of the layout of the low-voltage system, the various assembly positions in the assembly cavity 4 can be allocated, which facilitates the installation and fixing of various wiring switches in the assembly cavity 4.
[0018] Meanwhile, the assembly cavity 4 is connected to the outside through the snap-fit hole 6, the connecting cavity 5, and the heat dissipation groove 7, which facilitates the entry of external air into the assembly cavity 4. The circulation of external air in the assembly cavity 4 can effectively dissipate heat from the wiring switches installed in the assembly cavity 4, maintain the stability of the working environment of each wiring switch, and ensure the smooth operation of data signal transmission.
[0019] like Figure 3 and Figure 4 As shown, the snap-fit mechanism 9 includes a mounting cavity 91, which is located within the partition 8. A snap-fit bracket 92 is slidably connected within the mounting cavity 91. A sliding groove 93 penetrating the partition 8 is provided at the top of the mounting cavity 91. A handle block 94 penetrating the sliding groove 93 is integrally formed at the top of the snap-fit bracket 92. The handle block 94 facilitates gripping the snap-fit bracket 92. A telescopic shaft 95 is fixedly mounted between one side wall of the snap-fit bracket 92 and the mounting cavity 91. A spring 97 is sleeved on the outer side wall of the telescopic shaft 95. A snap-fit block 96 penetrating the mounting cavity 91 is fixedly mounted on the other side wall of the snap-fit bracket 92. The spring 97 generates elastic force on the snap-fit bracket 92. The snap-fit block 96 is inserted into the snap-fit hole 6 to fix the position of the partition 8 within the mounting cavity 4. At the same time, the snap-fit bracket 92 is moved by the handle block 94, and the snap-fit block 96 is moved out of the snap-fit hole 6, which can separate the partition 8 from the mounting cavity 4, facilitating the adjustment of the fixed position of the partition 8.
[0020] like Figure 3 As shown, a guide shaft 98 that passes through the snap-fit bracket 92 is fixedly installed in the sliding groove 93. By setting the guide shaft 98, the movement stroke of the snap-fit bracket 92 can be effectively limited, ensuring the accuracy of the movement stroke of the snap-fit bracket 92 in the mounting cavity 91.
[0021] like Figure 3 As shown, the sidewall of the partition 8 is evenly provided with cable management grooves 10. The cable management grooves 10 facilitate the sorting and organization of the cables connected to the terminals assembled in the assembly cavity 4, which is convenient for subsequent maintenance and repair.
[0022] like Figure 1 and Figure 2 As shown, a dustproof net 11 is embedded in the heat dissipation slot 7. The dustproof net 11 can effectively prevent dust from entering the interior of the cabinet 1, thereby affecting the normal operation of the wiring switches installed inside.
[0023] Working principle: such as Figure 1 As shown, in the layout of low-voltage electrical engineering in a building, this utility model allocates the assembly space within the assembly cavity 4 according to the layout requirements. The installation space of each electronic component within the assembly cavity 4 is separated by the partition 8, which facilitates the assembly of different types of wiring switches and other electronic components into their corresponding installation spaces, making subsequent maintenance and repair easier. The partition 8 is fixed by a snap-fit mechanism 9 and snap-fit holes 6. Adjusting the position of the partition 8 within the assembly cavity 4 is simple, convenient, and easy to operate. At the same time, during the overall assembly and operation of the electronic components, the snap-fit holes 6 not only achieve the effect of snap-fit fixing the partition 8, but also cooperate with the connecting cavity 5 and the heat dissipation groove 7 to facilitate airflow within the assembly cavity 4, effectively dissipating heat from the electronic components and maintaining a stable operating environment.
