Description

Technical Field

[0001] This utility model relates to the field of cabinet technology, specifically to a low-voltage electrical cabinet with a quick-release dustproof door. Background Technology

[0002] In practical applications of low-voltage electrical cabinets, dust prevention is of paramount importance. These cabinets typically house various sophisticated low-voltage devices, such as switches, routers, and servers. These devices have stringent environmental requirements; dust intrusion not only affects heat dissipation, leading to increased temperatures, but can also penetrate the equipment, causing short circuits, component damage, and other issues, thus severely impacting the equipment's normal operation and lifespan.

[0003] However, existing dustproof doors for low-voltage equipment cabinets have many drawbacks. Firstly, the installation of dustproof doors is extremely inconvenient. Traditional dustproof door installation often requires various tools, such as screwdrivers and wrenches, for complex fixing operations, making the process cumbersome and time-consuming. Secondly, disassembling the dustproof door is equally difficult during subsequent maintenance, repair, or upgrades of the equipment inside the cabinet, requiring significant time and effort to remove various fixing devices. This not only reduces maintenance efficiency but also increases maintenance costs.

[0004] On the other hand, the dustproof effect of existing dustproof doors is not satisfactory. Many dustproof doors only use a simple filter structure. The pore size of this filter is relatively large, which can only block some larger dust particles, and it is difficult to effectively intercept fine dust and impurities. Moreover, the filter is prone to clogging. Once clogged, it will not only affect the ventilation and heat dissipation of the cabinet, but also further reduce the dustproof effect. Utility Model Content

[0005] In order to overcome the shortcomings of existing technical solutions, this utility model provides a low-voltage motor cabinet with a quick-release dustproof door, which can effectively solve the technical problems of inconvenient cabinet door disassembly and poor dustproof effect of current low-voltage motor cabinets.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A low-voltage electrical cabinet with a quick-release dustproof door includes a cabinet body and a dustproof door located at the front of the cabinet body.

[0008] The cabinet is provided with a mounting groove for installing a dustproof door.

At each of the four corners of the annular protrusion, a guide rod extending along the depth direction of the cabinet is provided. Neodymium iron boron magnetic strips that are staggered with the guide rods are also embedded in the annular protrusion.

[0009] The back of the dustproof door is provided with an annular groove that matches the annular protrusion. The bottom of the annular groove is provided with several guide grooves corresponding to the shape and position of the guide rod and metal parts that are magnetically attracted to each neodymium iron boron magnetic strip. When the dustproof door is pushed along the direction of the guide rod through the guide groove, the dustproof door and the mounting groove are limited by the annular groove and the annular protrusion, and are fixed by the metal parts attracted to the neodymium iron boron magnetic strip.

[0010] The dustproof door has a through hole on the inside, and electrostatic dustproof mesh can be detachably installed at both ends of the hole. Filter cotton, which is clamped and fixed by the electrostatic dustproof mesh on both sides, is also installed in the hole.

[0011] Furthermore, the mounting groove is provided with a first notch on both sides, which connects to the two sides of the cabinet. The dustproof door is provided with a handle extending into and accommodating the first notch on both sides. The outer side of the handle is provided with a recessed anti-slip groove.

[0012] Furthermore, each side of the dustproof door is provided with an extension patch that extends and fits onto the sides of the cabinet, and a locking element is installed on the extension patch to lock and fix it to the cabinet.

[0013] Furthermore, the mounting groove has a second notch on both sides that connects to the two sides of the cabinet, and the extension patch is accommodated in the second notch and bent and attached to the two sides of the cabinet.

[0014] Furthermore, both sides of the dustproof door are provided with dustproof mesh mounting grooves for installing electrostatic dustproof mesh, and the electrostatic dustproof mesh is provided with a limiting edge strip in the circumferential direction and fixed to the dustproof mesh mounting groove.

[0015] Furthermore, one side of the edge strip is provided with several limiting rods inserted inside the filter cotton.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-3 As shown, this utility model provides a low-voltage electrical cabinet with a quick-release dustproof door. Through a unique structural design, it achieves the effect of quick disassembly and installation of the dustproof door, while optimizing the dustproof effect.

[0027] The low-voltage electrical cabinet provided in this solution mainly includes a cabinet body 1 and a dustproof door 2 located at the front end of the cabinet body 1. The cabinet body 1 is used to house and protect the low-voltage electrical equipment, while the dustproof door 2 is used to prevent dust from entering the interior of the cabinet body 1 and to ensure the normal operation of the equipment.

[0028] To facilitate the assembly of the dustproof door 2, the cabinet 1 is provided with a mounting groove 101 for installing the dustproof door 2. The bottom of the mounting groove 101 is provided with an annular protrusion 102 that protrudes upward and is embedded in the back of the dustproof door 2. This structure allows the dustproof door 2 to be accurately positioned in the mounting groove 101, and the annular protrusion 102 can provide a certain degree of support and limiting function.

[0029] At each of the four corners of the annular protrusion 102, a guide rod 103 extending along the depth direction of the cabinet 1 is provided. Correspondingly, the back of the dustproof door 2 is provided with an annular groove 201 that matches the annular protrusion 102. The bottom of the annular groove 201 is provided with several guide grooves 202 that correspond to the shape and position of the guide rods 103. When the dustproof door 2 needs to be installed, it can be easily connected or separated from the mounting groove 101 by simply pushing the dustproof door 2 along the direction of the guide rods 103.

[0030] The annular protrusion 102 is also embedded with neodymium iron boron magnetic strips 104 that are staggered with the guide rod 103. Correspondingly, the bottom of the annular groove 201 of the dustproof door 2 is provided with metal parts 203 that are magnetically attracted to each neodymium iron boron magnetic strip 104. When the dustproof door 2 is pushed into the mounting groove 101, the metal parts 203 and the neodymium iron boron magnetic strips 104 attract each other, thereby firmly fixing the dustproof door 2 to the cabinet 1. This magnetic fixing structure is not only easy to operate, but also has a reliable fixing effect.

[0031] For ease of operation, the mounting groove 101 has first notches 105 on both sides that connect to the two sides of the cabinet 1, and the dustproof door 2 has handles 207 on both sides that extend into and are accommodated in the first notches 105. The outer side of the handles 207 has recessed anti-slip grooves 208, which increases the friction between the hand and the handles 207, making the operation more stable and reliable.

[0032] To further enhance the connection stability between the dustproof door 2 and the cabinet 1, each side of the dustproof door 2 is provided with an extension patch 209 that extends and fits against both sides of the cabinet 1. A locking element 210 is installed on the extension patch 209 to lock and fix it to the cabinet 1. The locking action of the locking element 210 ensures that the dustproof door 2 will not easily detach when subjected to external force.

[0033] To facilitate the application of the extension patch 209 and the installation of the locking element 210, second notches 106 connecting to the two sides of the cabinet 1 are provided on both sides of the mounting groove 101. The extension patch 209 can be accommodated in the second notches 106 and bent to fit against the two sides of the cabinet 1, thereby achieving a tight connection between the dustproof door 2 and the cabinet 1.

[0034] The inner side of the dustproof door 2 has a through-hole 204 on both sides, and both ends of the hole 204 can be detachably fitted with an electrostatic dustproof mesh 205. The electrostatic dustproof mesh 205 can effectively adsorb dust particles in the air and prevent them from entering the cabinet 1. At the same time, a filter cotton 206 is also installed inside the hole 204, which is held and fixed by the electrostatic dustproof mesh 205 on both sides. The filter cotton 206 can further filter the fine particles in the air and improve the dustproof effect.

[0035] Both sides of the dustproof door 2 are provided with dustproof mesh mounting grooves 211 for installing electrostatic dustproof mesh 205. The electrostatic dustproof mesh 205 is provided with a circumferentially limited edge strip 212 that is fixed to the dustproof mesh mounting groove 211. The edge strip 212 not only protects the electrostatic dustproof mesh 205 from damage, but also ensures a tight fit between the electrostatic dustproof mesh 205 and the dustproof door 2.

[0036] To further enhance the stability of the filter cotton 206 within the pores 204, one side of the edge strip 212 is provided with several limiting rods 213 that insert inside the filter cotton 206. The limiting rods 213 can prevent the filter cotton 206 from shifting or falling off during use, thereby ensuring the durability of the dustproof effect.

[0037] In summary, the low-voltage electrical cabinet with a quick-release dustproof door provided in this solution achieves rapid disassembly and secure fixing of the dustproof door through a unique installation method. Furthermore, the dustproof structure on the door is optimized to improve dustproof performance. This low-voltage electrical cabinet structure is not only easy to operate and reliable, but also has broad applicability and promotional value.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
