Description

Technical Field

[0001] This utility model relates to the field of switch control cabinet technology, and in particular to a combined low-voltage switch control cabinet. Background Technology

[0002] Low-voltage switchgear is an indispensable basic equipment in power systems, widely used for the distribution, control, metering, and protection of electrical energy. It houses various electrical components such as circuit breakers, contactors, relays, and instruments, ensuring the safe and stable operation of the power system.

[0003] In many industrial automation, large building, or data center applications, a large number of electrical components are required, and a single standard-sized control cabinet often cannot meet all the installation space requirements. To solve this problem, the industry commonly uses the method of combining multiple control cabinets side by side to expand the overall capacity.

[0004] Existing assembly methods typically involve placing multiple cabinets side-by-side and then securing the side walls of adjacent cabinets together using bolts or connecting plates on the outside. While this method enables cabinet assembly, it has revealed shortcomings in practical applications.

[0005] On the one hand, this connection method, which relies on external fasteners, has a relatively cumbersome structure and is not convenient to install and disassemble, especially in space-constrained environments. On the other hand, when multiple cabinets are combined into an array, the side wall through-holes of the outermost cabinet, which are used for connection, are exposed. How to effectively and standardly seal these unused through-holes to ensure that the entire combined cabinet meets the dustproof, moisture-proof, and other protection levels required for industrial applications is a problem that urgently needs to be solved in existing technologies. Existing sealing measures often rely on temporary baffles or sealants, lacking standardized structures, resulting in low sealing reliability.

[0006] Therefore, this utility model proposes a combined low-voltage switch control cabinet to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems of complex combination connection structure, inconvenient installation, and low sealing reliability of unused connection holes in the existing modular low-voltage switch control cabinet, this utility model aims to provide a modular low-voltage switch control cabinet with improved structure that can effectively solve the above problems.

[0008] This utility model provides a combined low-voltage switch control cabinet, including: a cabinet body, on which through holes are provided on the side wall; and a connecting mechanism and a sealing mechanism.

[0009] The sealing mechanism includes a baffle and screws; the connecting mechanism includes a connecting pipe, a fixing ring, and a threaded ring.

[0010] The connecting pipe passes through the through holes of two adjacent cabinets. One end of the connecting pipe is fixedly connected to the fixing ring, which is detachably fixed to the inner wall of one of the cabinets by the screw of the sealing mechanism. The other end of the connecting pipe is threaded, and the threaded ring is threadedly connected to the other end of the connecting pipe and abuts against the inner wall of the adjacent cabinet. Through this connecting mechanism set inside the cabinet, the two cabinets are firmly spliced ​​together.

[0011] Furthermore, the baffle is detachably fixed inside the cabinet by the screws to block the through hole, and this sealing mechanism provides a standardized sealing solution for the outermost cabinet after assembly.

[0012] Preferably, the outer wall of the threaded ring is fixedly connected to a handle. This structure is designed to facilitate the user's grip and application of force when tightening or loosening the threaded ring, greatly improving the ease of installation and disassembly.

[0013] Preferably, the connecting pipe is a hollow tube. Its hollow structure not only realizes the physical connection between cabinets, but also forms a protected internal channel through which the wires of electrical components can pass. This not only realizes the electrical interconnection between cabinets, but also makes the wiring more organized and safe.

[0014] Preferably, a fixing rod is also fixedly connected inside the cabinet. The fixing rod serves as a standardized installation benchmark, providing a stable support platform for the installation of various electrical components and ensuring the reliability of component installation.

[0015] Furthermore, the cabinet interior also includes electrical components, which are installed on the outer wall of the fixing rod, making the internal layout of the cabinet neat and orderly, and facilitating maintenance and repair.

[0016] Preferably, the cabinet has a hinged door panel at the opening, which is used to seal the interior space of the cabinet and protect the internal components from external environmental factors such as dust and moisture.

[0017] Preferably, the door panel is provided with a lock hole, which can be used with a corresponding lock to lock the door panel, effectively preventing unauthorized personnel from opening the cabinet door, thereby improving the overall security of the equipment operation.

[0018] Preferably, the fixing ring has a mounting hole for the screw to pass through. This mounting hole provides precise positioning for the screw to pass through and be fixed, ensuring that the fixing ring can be stably and reliably fixed to the inner wall of the cabinet, thereby enhancing the stability of the entire connection mechanism.

[0019] This utility model has the following beneficial effects: 1. This utility model, by setting a connecting mechanism and a sealing mechanism that can be operated inside the cabinet, wherein the connecting mechanism is a connecting pipe with a fixing ring at one end and a thread at the other end, which passes through the through holes of two adjacent cabinets and is tightened inside the cabinet by using the threaded ring to clamp and fix the two cabinets. At the same time, the sealing mechanism seals the through hole of the outermost cabinet by using a baffle and screws. This solves the problems of complex connection structure, inconvenient operation, poor connection reliability and poor sealing effect of the existing modular cabinet 1, and achieves the technical effect of simple structure, convenient assembly and disassembly, firm and reliable connection and good sealing performance.

[0020] 2. This utility model solves the problem of easy external disassembly of connecting parts and low security in the prior art by setting the fastening operations of the connecting mechanism and sealing mechanism inside the cabinet. It achieves the technical effect of making it impossible to disassemble the combined cabinet from the outside after the cabinet door is closed and locked, thereby effectively improving the overall security and anti-vandalism capability of the equipment.

[0021] 3. This utility model solves the problem of inconvenient wiring or lack of effective protection between combined cabinets in the prior art by designing the connecting tube in the connecting mechanism as a hollow tube structure. It achieves the technical effect of providing a safe and orderly internal channel for wires across cabinets, simplifying wiring work and improving electrical safety. Attached Figure Description

[0028] Please refer to the following carefully. Figure 1 , Figure 3 and Figure 4 The connecting mechanism 3 includes a connecting tube 304, a fixing ring 303, a threaded ring 301, and a handle 302 fixedly connected to the outer wall of the threaded ring 301. The connecting tube 304 is a hollow tube with a fixing ring 303 fixedly connected to one end and a thread on the other end. The connecting tube 304 passes through the through holes of two adjacent cabinets 1. The fixing ring 303 has a mounting hole for a screw 402 to pass through. The fixing ring 303 is detachably fixed to the inner wall of one cabinet 1 by the screw 402. The threaded ring 301 is threadedly connected to the threaded end of the connecting tube 304 and abuts against the inner wall of the adjacent cabinet 1 in the locked state.

[0031] The working principle of this modular low-voltage switch control cabinet is as follows: When assembling cabinet 1, first open door panel 2 through lock hole 5, and place the side walls of the two cabinets 1 together so that the through holes of the side walls are aligned; then, pass the connecting tube 304 of the connecting mechanism 3 through the through hole of one cabinet 1 and continue to pass through the through hole of the adjacent cabinet 1; inside the first cabinet 1, pass screw 402 through the mounting hole of the fixing ring 303 for passing screw 402, and fix the fixing ring 303 detachably to the inner wall of the cabinet 1; inside the adjacent cabinet 1, rotate the threaded ring 301 with handle 302 so that the threaded ring 301 engages with the thread of the connecting tube 304 and is tightened until the end face of the threaded ring 301 abuts against the inner wall of the adjacent cabinet 1, thereby firmly connecting the two cabinets 1 together. After the connection is completed, the wires of the electrical components 7 can pass through the connecting tube 304 with the hollow tube structure to realize the electrical connection between the cabinets 1.

[0032] When it is necessary to seal the outermost through hole of the combined cabinet 1, the baffle 401 of the sealing mechanism 4 is taken from inside the cabinet 1 to cover the through hole, and the baffle 401 is detachably fixed to the inner wall of the cabinet 1 with screws 402 to achieve effective sealing of the through hole and prevent external dust or moisture from entering; the electrical components 7 of the entire device are all installed on the fixing rod 6 inside the cabinet 1. Through the synergistic effect of the connecting mechanism 3 and the sealing mechanism 4, this utility model solves the problem of complex connection and poor sealing of the combined cabinet 1 in the prior art and provides a flexible and reliable expansion solution.
