Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electrical switch cabinet technology, and relates to an electrical switch cabinet with high protection. Background Technology
[0002] An electrical switchgear is a metal cabinet specifically designed for the installation and protection of electrical equipment. It provides a safe and orderly installation environment for various electrical switches, relays, circuit breakers, and other devices. These switchgear cabinets are typically installed in industrial, commercial, and residential buildings to ensure the stable operation and safe functioning of power systems. Electrical modules are frequently installed on the cabinet doors of electrical switchgear. These modules include, but are not limited to, control modules, protection modules, and measurement modules, each performing different functions, such as controlling the opening and closing of circuits, protecting circuits from overload or short-circuit damage, and monitoring circuit current and voltage. Installing these modules on the switchgear doors facilitates daily monitoring and maintenance, while also making electrical system management more efficient and intuitive.
[0003] However, in existing electrical switchgear, the cabinet door switches usually lack limit position restrictions, which makes it easy for the cabinet door to collide with adjacent cabinets or wall columns when it is opened too wide, resulting in damage to the electrical modules on the cabinet door. Therefore, it is necessary to design an electrical switchgear with high protection. Summary of the Invention
[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a highly protective electrical switch cabinet.
[0005] The objective of this utility model can be achieved through the following technical solution: A highly protective electrical switch cabinet includes a cabinet body and a cabinet door hinged to the cabinet body. An electrical module is installed on the cabinet door. The cabinet body is characterized by an arc-shaped fixing component connected to it, with a guide groove on the arc-shaped fixing component. The cabinet door is connected to an arc-shaped movable component, with a pin vertically slidably mounted at the end of the arc-shaped movable component. The pin is also arranged within the guide groove. The pin includes a lower guide rod portion and an upper locking rod portion. The diameter of the lower guide rod portion is smaller than the width of the guide groove, and the diameter of the upper locking rod portion is larger than the width of the guide groove. The end of the arc-shaped fixing component also has a locking slot communicating with the guide groove, and the upper locking rod portion can be engaged into the locking slot.
[0006] The cabinet door is hinged to the cabinet body.
[0007] The cabinet is also equipped with rotatable rollers, and the cabinet door is also equipped with auxiliary positioning blocks that cooperate with the rollers. The auxiliary positioning blocks have an inclined guide surface and a horizontal abutment surface.
[0008] The cabinet is also equipped with rollers that rotate via a mounting shaft.
[0009] The auxiliary positioning block is fixed to the cabinet door by a mounting plate.
[0010] Compared with existing technologies, this highly protective electrical switchgear has the following advantages:
[0011] This utility model uses the combined use of arc-shaped fixing parts, arc-shaped moving parts and pin shafts to limit the extreme position of the cabinet door when it is opened, effectively preventing the electrical modules on the cabinet door from colliding with other electrical switch cabinets and being damaged due to excessive opening of the cabinet door, thus providing good protective performance.

Detailed Implementation
[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0018] like Figures 1-4As shown, this highly protective electrical switch cabinet includes a cabinet body 1 and a cabinet door 7 hinged to the cabinet body 1. An electrical module 6 is installed on the cabinet door 7. Specifically, the electrical module 6 includes a display screen and an electrical switch. In this embodiment, the electrical module 6 uses existing products. An arc-shaped fixing member 9 is connected to the cabinet body 1. A guide groove 9a is provided on the arc-shaped fixing member 9. An arc-shaped movable member 3 is connected to the cabinet door 7. A pin 8 is vertically slidably installed at the end of the arc-shaped movable member 3. The pin 8 is also arranged in the guide groove 9a. The pin 8 includes a lower guide rod part 8a and an upper locking rod part 8b. The diameter of the lower guide rod part 8a is smaller than the groove width of the guide groove 9a. The diameter of the upper locking rod part 8b is larger than the groove width of the guide groove 9a. The end of the arc-shaped fixing member 9 also has a locking port 9b that communicates with the guide groove 9a. The upper locking rod part 8b can be inserted into the locking port 9b.
[0019] Cabinet door 7 is hinged to cabinet body 1 via hinge 11.
[0020] The cabinet body 1 is also equipped with a rotatable roller 2, and the cabinet door 7 is also equipped with an auxiliary positioning block 4 that cooperates with the roller 2. The auxiliary positioning block 4 has an inclined guide surface 4a and a horizontal abutment surface 4b. With this structure, since the cabinet door 7 is equipped with an electrical module 6, the cabinet door 7 may swing down unexpectedly after long-term use. By cooperating with the roller 2, the auxiliary positioning block 4 can play a positioning role when the cabinet door 7 is closed, so that the cabinet door 7 is in the normal position when closed, and can be locked by the existing door locking components.
[0021] The cabinet 1 is also equipped with rollers 2 that rotate via the mounting shaft 10.
[0022] The auxiliary positioning block 4 is fixed to the cabinet door 7 by the mounting piece 5.
[0023] This utility model uses the combined use of the arc-shaped fixing part 9, the arc-shaped movable part 3 and the pin 8 to limit the extreme position of the cabinet door 7 when it is opened, effectively preventing the electrical module 6 on the cabinet door 7 from being damaged by collision with other electrical switch cabinets due to excessive opening of the cabinet door 7, thus providing good protective performance.
[0024] In this embodiment, after the cabinet door 7 is opened to its limit position, the upper locking rod 8b can be engaged into the lock 9b to lock the position of the cabinet door 7. When it is necessary to close the cabinet door 7, simply pull the upper locking rod 8b upward from the lock 9b.
[0025] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.
[0026] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
