Description

Technical Field

[0001] This application relates to the field of switch cabinet technology, and more specifically, to a door anti-fall bracket for a switch cabinet and the switch cabinet itself. Background Technology

[0002] As a key component of power equipment, switchgear doors are being designed towards integration and higher efficiency. With the increasing number of electronic components and rising functional requirements, door structures need to balance structural strength with space utilization. Industry trends emphasize lightweighting and cost optimization, driving door designs to adapt to more compact cabinet layouts and more economical manufacturing processes while ensuring stability. This development helps improve the overall performance and reliability of switchgear, meeting the growing market demands.

[0003] However, in existing technologies, switch cabinet doors are prone to loosening, sagging, or even falling off during long-term use. To address this issue, longitudinal and transverse reinforcing ribs are typically installed on the inner side of the door to enhance its support strength, or linkage structures are added to the hinges. These methods require specific space to be reserved inside the cabinet, significantly reducing the usable space and affecting the arrangement of other components and the overall cabinet capacity, thus limiting design flexibility. Furthermore, the use of reinforcing ribs increases material consumption and production costs, negatively impacting economic efficiency and resource utilization. Therefore, effectively reducing space occupation and controlling costs while ensuring the long-term stability of the door has become a key challenge for technological improvement.

[0004] There is currently no effective technical solution to the above problems. Utility Model Content

[0005] The purpose of this application is to provide a door anti-fall bracket for a switch cabinet and a switch cabinet, so as to solve the problems of loosening, sagging or even falling of the switch cabinet door during long-term use. At the same time, it avoids the disadvantages of traditional methods that increase the internal space, material consumption and production cost caused by adding reinforcing ribs or hinges, thereby achieving the effects of saving space, reducing costs and improving door stability.

[0006] In a first aspect, this application provides a door anti-fall bracket for a switch cabinet, used to support the door when the switch cabinet door is closed. The bracket includes a bracket body, one side of which has a horizontally extending first groove, and the bottom of the bracket body has a supporting surface for abutting against the inner bottom plate of the switch cabinet when the switch cabinet door is closed. The supporting surface has a rounded corner edge on the side opposite to the first groove, and the middle of the bracket body has a process hole for being locked and installed on the door of the switch cabinet by bolts.

[0007] The anti-fall bracket for the switch cabinet door of this application solves the problems of loosening, sagging, and even falling of the switch cabinet door during long-term use. At the same time, it avoids the drawbacks of traditional methods that involve adding reinforcing ribs or hinges, such as large space occupation, high material consumption, and increased production costs. It achieves the effects of saving space, reducing costs, and improving door stability.

[0008] The switch cabinet door anti-fall bracket includes a mounting bracket and a limiting bracket. The first sliding groove and the process hole are provided on the mounting bracket, and the supporting surface and the rounded corner edge are provided on the limiting bracket. The limiting bracket is height-adjustable and mounted on the mounting bracket.

[0009] This example separates the functions of the bracket body and introduces a height adjustment mechanism, enabling the bracket body, which was originally a whole, to more accurately adapt to different installation conditions and wear and tear. This effectively solves the problems of unstable door support and difficulty in adjustment. At the same time, it simplifies the alignment requirements during installation, improves installation efficiency and the convenience of later maintenance.

[0010] The switch cabinet door anti-fall bracket has a second vertically extending slide groove on the side of the mounting bracket away from the first slide groove. The limiting bracket is slidably installed on the second slide groove, and the limiting bracket has a straight groove for height locking with bolts.

[0011] The door anti-fall bracket of the switch cabinet has anti-slip textures on the bottom of the second slide groove and / or the side wall of the limiting bracket that abuts against the bottom of the second slide groove.

[0012] The switch cabinet door anti-fall bracket has limiting protrusions on both sides of the bottom.

[0013] The switch cabinet door anti-fall bracket has extensions on both sides that fit with the bottom of the second sliding groove.

[0014] The switch cabinet door anti-fall bracket is wherein the bracket body is locked and installed on the switch cabinet door by a bolt passing through the straight groove and the process hole.

[0015] The switch cabinet door anti-fall bracket has a weight-reducing groove located above the rounded corner edge.

[0016] Secondly, this application also provides a switch cabinet, the switch cabinet including: a door body, a fixing base, and a door anti-fall bracket as provided in the first aspect of the switch cabinet, the fixing base being fixed to the bottom of the inner side of the door body, and the door anti-fall bracket of the switch cabinet being connected to the fixing base by bolts to be fixed on the door body.

[0017] This application's switchgear solves the problem of loose or damaged installation points due to insufficient local load-bearing capacity of the door body by fixing the mounting base to the bottom inside the door and connecting the door anti-fall bracket to the mounting base with bolts. This avoids unnecessary stress accumulation or damage to the door body itself. The mounting base, as an intermediate connector, provides a pre-set, stable installation benchmark for the anti-fall bracket, improving installation accuracy and simplifying the installation process. This switchgear effectively supports the anti-fall bracket, preventing the door connection from loosening, moving downwards, or even falling.

[0018] In the aforementioned switch cabinet, the fixing base is a U-shaped buckle with bent plates on both sides, and the fixing base is welded and fixed to the door body by the bent plates.

[0019] As can be seen from the above, this application provides a door anti-fall bracket for switch cabinets and a switch cabinet. The door anti-fall bracket of this application introduces an anti-fall bracket that can directly support the bottom of the switch cabinet when the switch cabinet door is closed, and makes its bottom support surface abut against the inner bottom plate of the switch cabinet. This solves the problem of loosening, sagging, and even falling of the switch cabinet door during long-term use. At the same time, it avoids the disadvantages of traditional methods that involve adding reinforcing ribs or hinges, such as large space occupation, high material consumption, and increased production costs. This achieves the effects of saving space, reducing costs, and improving door stability. Attached Figure Description

[0031] Firstly, please refer to Figures 1-3 Some embodiments of this application provide a door anti-fall bracket for a switch cabinet, used to support the door 2 of the switch cabinet when it is closed. The bracket includes a bracket body 1, a first horizontally extending groove 111 on one side of the bracket body 1, a supporting surface 121 at the bottom of the bracket body 1 for abutting against the inner bottom plate 3 of the switch cabinet when the door 2 of the switch cabinet is closed, a rounded corner edge 122 on the side of the supporting surface 121 facing away from the first groove 111, and a process hole 112 in the middle of the bracket body 1 for locking and installing on the door 2 of the switch cabinet by bolts 4.

[0032] Specifically, the door anti-fall bracket of this application is used to support the door 2 of the switch cabinet when it is closed. This means that the main function of the bracket is to provide upward support when the switch cabinet door 2 is closed, to share the weight of the door 2 or external stress, thereby maintaining the stable position of the door 2. The bracket body 1 refers to the main structure of the anti-fall bracket, which is the foundation for supporting other functional components. The horizontally extending first groove 111 refers to a groove-shaped structure extending horizontally on the side of the bracket body 1. It can be implemented in the form of a dovetail groove, T-groove, or rectangular groove, and is mainly used for guiding installation, limiting fit, or sliding connection with other components to achieve the positioning or adjustment function of the bracket. The supporting surface 121 refers to the flat or curved surface at the bottom of the bracket body 1 that contacts the inner bottom plate 3 of the switch cabinet when the switch cabinet door 2 is closed. It can be implemented as a flat surface, an arc surface, or a contact surface with anti-slip texture. It is mainly used to transfer part of the weight of the door 2 to the cabinet bottom plate, providing direct bottom support and preventing the door 2 from falling. The rounded edge 122 refers to the rounded edge of the supporting surface 121 on the side away from the first slide groove 111. This can be achieved using an R-angle, C-angle, or multi-segment arc transition. It primarily reduces the impact and friction between the door 2 and the cabinet base plate or bracket itself when the door 2 closes, preventing scratches or jamming, thereby improving the smoothness of door 2 closure and the durability of the bracket, and enhancing the overall system reliability. The process hole 112 refers to the hole in the middle of the bracket body 1 for installing bolts 4. It can be achieved using through holes, blind holes, or countersunk holes. It is mainly used to securely fix the bracket to the switch cabinet door 2 with bolts 4, ensuring the bracket can perform its supporting function.

[0033] Specifically, the bracket body 1 is securely mounted on the switch cabinet door 2 via bolts 4 through the central process hole 112. When the switch cabinet door 2 is closed, the support surface 121 at the bottom of the bracket body 1 precisely abuts against the inner bottom plate 3 of the switch cabinet. This direct contact and support mechanism allows part of the weight of the door 2 to be transferred to the bottom plate of the cabinet through the bracket body 1, thereby sharing the load-bearing capacity of the door 2 hinge. The horizontally extending first slide groove 111 on one side of the bracket body 1 provides guidance and limiting for the installation or subsequent adjustment of the bracket. The rounded corner edge 122 on the side of the support surface 121 facing away from the first slide groove 111 ensures smooth and stable contact between the bracket and the bottom plate of the cabinet during the closing process of the door 2, reducing friction and potential jamming, and improving the reliability and service life of the system. Through this structural combination, the anti-fall bracket forms a stable bottom support point when the door 2 is closed, which fundamentally prevents the door 2 from loosening, falling or even falling off due to long-term self-weight or external stress, and ensures the long-term stability and safety of the switch cabinet door 2.

[0034] This anti-fall bracket enhances the stability of door 2 and extends its service life by providing direct bottom support when the door is closed. Simultaneously, it saves cabinet space and improves the flexibility of internal component placement and overall capacity by eliminating the need for reinforcing ribs or additional hinges with linkage structures on the inside of door 2. Furthermore, this solution simplifies the door 2 structure, reduces material consumption and production costs, and improves economic efficiency and resource utilization, providing an efficient, reliable, and economical solution for the design of switch cabinet doors.

[0035] The switch cabinet door anti-fall bracket of this application introduces an anti-fall bracket that can directly support the bottom of the switch cabinet door 2 when the switch cabinet door 2 is closed, and makes its bottom support surface 121 abut against the inner bottom plate 3 of the switch cabinet. This solves the problem of loosening, sagging and even falling of the switch cabinet door 2 during long-term use. At the same time, it avoids the disadvantages of traditional methods that increase cabinet space, material consumption and production costs caused by adding reinforcing ribs or hinges. It achieves the effects of saving space, reducing costs and improving the stability of the door 2.

[0036] In some implementations, such as Figure 1 As shown, the support body 1 is integrally formed; in some other embodiments, such as Figure 2 and Figure 3 As shown, the support body 1 is a split structure.

[0037] In some preferred embodiments, the bracket body 1 includes a mounting bracket 11 and a limiting bracket 12. A first sliding groove 111 and a process hole 112 are provided on the mounting bracket 11, and a supporting surface 121 and a rounded corner edge 122 are provided on the limiting bracket 12. The limiting bracket 12 is mounted on the mounting bracket 11 with adjustable height.

[0038] Specifically, this solution achieves height adjustment capability by decomposing the bracket body 1 into two independent components: a mounting bracket 11 and a limiting bracket 12. The mounting bracket 11 is equipped with a first sliding groove 111 and a process hole 112, allowing it to be stably fixed to the switchgear door 2, providing a fixed installation reference for the entire bracket system. The supporting surface 121 and rounded corner edge 122 are provided on the limiting bracket 12, allowing the functional part that actually bears the weight of the door 2 and contacts the inner bottom plate 3 of the switchgear to be independent. The limiting bracket 12 is height-adjustably mounted on the mounting bracket 11, meaning that the limiting bracket 12 can move and be positioned vertically relative to the mounting bracket 11. This adjustability allows the supporting surface 121 to be precisely height-matched according to the actual conditions of the switchgear, such as manufacturing tolerances, differences in installation environment, or structural deformation caused by long-term use. When the door 2 is closed, adjusting the height of the limiting bracket 12 ensures that the supporting surface 121 is in close contact with the inner bottom plate 3 of the switchgear, thus providing stable and reliable support. This split, adjustable design overcomes the limitations of traditional fixed-height supports that cannot adapt to various working conditions, ensuring effective support for the door 2, preventing the door 2 from loosening or sagging, and improving the stability and reliability of the support. By separating the functions of the support body 1 and introducing a height adjustment mechanism, the original single support body 1 can more precisely adapt to different installation conditions and wear and tear, thus effectively solving the problems of unstable support and difficulty in adjustment of the door 2. At the same time, it simplifies the alignment requirements during installation, improves installation efficiency, and enhances the convenience of later maintenance.

[0039] In some preferred embodiments, the mounting bracket 11 has a vertically extending second slide groove 113 on the side opposite to the first slide groove 111, and the limiting bracket 12 is slidably mounted on the second slide groove 113. The limiting bracket 12 has a straight groove 123 for height locking by bolt 4.

[0040] Specifically, the second groove 113 can be implemented using a C-shaped groove, T-shaped groove, or U-shaped groove, etc., to provide guidance for the vertical movement of the limiting bracket 12. The straight groove 123 refers to an elongated hole, which can be implemented using an oblong hole, rectangular groove, or elliptical hole, etc. The straight groove 123 is used to accommodate the bolt 4, and the limiting bracket 12 is fixed at the selected height position by the fastening action of the bolt 4.

[0041] Specifically, the mounting bracket 11 has a first sliding groove 111 and a process hole 112 for fixing the entire bracket to the switch cabinet door 2. The limiting bracket 12 has a supporting surface 121 and a rounded corner edge 122 for supporting the door 2 when it is closed. To achieve height adjustment of the limiting bracket 12, the mounting bracket 11 has a vertically extending second sliding groove 113 on the side opposite to the first sliding groove 111. The limiting bracket 12 is mounted on the second sliding groove 113 by sliding. This structure allows the limiting bracket 12 to move vertically up and down along the second sliding groove 113, thereby achieving flexible height adjustment. When the support height needs to be adjusted, the user can slide the limiting bracket 12 up and down within the second sliding groove 113 to adapt to different heights of the door 2 installation requirements or the door 2 sagging. Furthermore, to ensure that the adjusted limiting bracket 12 can be stably maintained at the selected height, the limiting bracket 12 has a straight groove 123 for height locking by bolts 4. After the limiting bracket 12 slides to the desired height, a bolt 4 passes through the straight groove 123 and is tightened. The tightening action of the bolt 4 creates friction or a mechanical connection between the limiting bracket 12 and the mounting bracket 11, thereby locking the limiting bracket 12 in its current position and preventing it from shifting or falling due to vibration or the force of the door 2 during use. Thus, the second sliding groove 113 on the mounting bracket 11 provides vertical guidance, the sliding of the limiting bracket 12 within the second sliding groove 113 achieves height adjustment, and the straight groove 123 on the limiting bracket 12, in conjunction with the bolt 4, achieves height locking. This solution provides a complete and operable height adjustment and locking mechanism for the limiting bracket 12. This allows the anti-fall bracket to be height-set according to actual needs and to maintain a stable position after setting, thereby continuously supporting the switch cabinet door 2 and solving the problem of potential loosening or falling of the door 2. This structural combination concretizes the original height adjustability from a conceptual level into an implementable mechanical structure and adds a crucial locking function, thereby improving the support function of the anti-fall bracket.

[0042] In some preferred embodiments, the bottom of the second groove 113 and / or the side wall of the limiting bracket 12 that abuts against the bottom of the second groove 113 are provided with anti-slip texture 114.

[0043] Specifically, anti-slip texture 114 refers to a textured structure set on the surface of an object to increase friction and prevent relative slippage. It can be implemented using various geometric shapes such as raised areas, grooves, grids, serrations, waves, or dots.

[0044] Specifically, to address the issue of insecure height locking, this application incorporates anti-slip textures 114 on the bottom of the second slide rail 113 and / or on the side wall of the limit bracket 12 abutting against the bottom of the second slide rail 113. When the bolt 4 is tightened, the anti-slip textures 114 increase the friction between the limit bracket 12 and the second slide rail 113. These textured structures mesh with each other or increase the roughness of the contact surface, thereby improving the locking stability of the limit bracket 12 in the vertical direction. Even if the switch cabinet door 2 is subjected to long-term loads, frequent opening and closing, or external vibrations and impacts, the anti-slip textures 114 effectively prevent the limit bracket 12 from accidentally sliding or falling, ensuring that the door anti-fall bracket can continuously and stably support the door 2 and maintain the set support height. This design makes the height-adjustable anti-fall bracket more reliable and safer in practical applications, solving the problem of height instability caused by insufficient friction or loose bolt 4 in the prior art, and improving the operational reliability and safety of the switch cabinet.

[0045] In some preferred embodiments, the bottom of both sides of the limiting bracket 12 has limiting protrusions 124.

[0046] Specifically, the limiting protrusion 124 refers to the protruding structure set at the bottom of both sides of the limiting bracket 12, which can be realized by means of flange, protrusion, or extension of a specific shape.

[0047] Specifically, when the limiting bracket 12 is installed in the second slide groove 113, the limiting protrusions 124 engage with the outer edge of the second slide groove 113 (the limiting protrusions 124 abut against the outer edge of the slide groove). This engagement reduces excessive wobbling of the limiting bracket 12 within the second slide groove 113, enhances the stability of the connection, and avoids the problem of deformation of the supporting surface 121 due to over-tightening of the limiting bracket 12.

[0048] In some preferred embodiments, the limiting bracket 12 has extensions 125 on both sides that fit with the bottom of the second slide groove 113.

[0049] Specifically, clearance fit refers to a certain, preset small gap between the extension 125 and the bottom of the second groove 113, which allows relative movement but restricts large-scale shaking. This can be achieved by precise machining tolerance control or by placing a small amount of lubricant or low-friction material between the extension 125 and the bottom of the groove.

[0050] Specifically, when the limiting bracket 12 is slidably installed on the second slide groove 113, the extensions 125 on both sides of the bracket form a clearance fit with the bottom of the second slide groove 113. This fit allows the limiting bracket 12 to be height-adjusted while providing additional lateral support and structural rigidity. Simultaneously, these extensions 125 can serve as reinforcing ribs for the limiting bracket 12, effectively distributing and bearing the load from the door body 2, enhancing the limiting bracket 12's resistance to deformation and overall stability, and preventing bending or swaying during long-term use.

[0051] In some preferred embodiments, the bracket body 1 is locked onto the door 2 of the switch cabinet by a bolt 4 passing through the straight groove 123 and the process hole 112.

[0052] Specifically, during installation, the limiting bracket 12 can slide up and down along the second sliding groove 113 on the mounting bracket 11 to adjust the height of its supporting surface 121 so that it can accurately contact the inner bottom plate 3 of the switch cabinet. Once the required height is determined, the user inserts a bolt 4 through the straight groove 123 on the limiting bracket 12 and the process hole 112 on the mounting bracket 11, and further fixes it to the door 2 of the switch cabinet. When the bolt 4 is tightened, it simultaneously applies pressure to the limiting bracket 12, firmly locking it at the selected height position and preventing displacement during subsequent use; at the same time, the bolt 4 also tightly fixes the entire bracket body 1 to the door 2 of the switch cabinet through the process hole 112. This integrated fastening method allows the installation and locking process, which originally might have required two independent operations or two fasteners, to be completed simultaneously with just one bolt 4. This not only simplifies the installation process and reduces the number of required parts, but also ensures the stability and precise alignment of the bracket on the door 2, effectively preventing the door 2 from loosening, sagging, or falling off during long-term use.

[0053] In some preferred embodiments, the support body 1 is provided with a weight-reducing groove 126 located above the rounded corner edge 122.

[0054] Specifically, the weight-reducing groove 126 refers to a groove or cavity formed inside or on the surface of a structural component to reduce material usage and overall weight. Its shape can be circular, elliptical, rectangular, irregular, or grid-like. Introducing the weight-reducing groove 126 can achieve lightweighting and cost optimization without significantly affecting structural strength and function.

[0055] Specifically, the weight-reducing groove 126 on the bracket body 1 directly reduces the overall weight and material consumption of the bracket body 1 by removing some material. The weight-reducing groove 126 is positioned above the rounded corner edge 122, which is part of the support surface 121 and is used to provide smooth contact and distribute stress. Placing the weight-reducing groove 126 above this area indicates that this area is not a major stress-bearing area when supporting the door body 2, or has structural redundancy. This precise positioning ensures that while achieving weight reduction, the key support capacity of the support surface 121 of the bracket body 1 and the function of the rounded corner edge 122 are not weakened. In this way, the bracket body 1 effectively reduces its own weight and material consumption while maintaining its support function and structural stability. This design allows the bracket body 1 to provide stable support while reducing the additional burden on the switch cabinet door body 2, which is in line with the trend of lightweighting and cost optimization. This combination allows the bracket body 1 to further optimize its structural efficiency and economy while meeting basic support functions, solving the weight and cost problems caused by traditional solid structures, and avoiding negative impacts on support performance.

[0056] Secondly, please refer to Figure 4 Some embodiments of this application also provide a switch cabinet, which includes: a door 2, a fixing seat 5, and a door anti-fall bracket as provided in the first aspect. The fixing seat 5 is fixed to the bottom inner side of the door 2, and the door anti-fall bracket of the switch cabinet is connected to the fixing seat 5 by bolts 4 to fix it on the door 2.

[0057] Specifically, the fixed base 5 refers to an intermediate structure used to connect the switch cabinet door 2 and the door anti-fall bracket, which can be implemented using a plate-shaped, block-shaped or irregular-shaped structure.

[0058] Specifically, this switch cabinet solution introduces a fixed base 5 as an intermediate connector between the door 2 and the anti-fall bracket, thus constructing a layered and stable support system.

[0059] The switchgear of this application solves the problem of loose or damaged installation points caused by insufficient local load-bearing capacity of the door body 2 by fixing the fixing base 5 to the bottom inner side of the door body 2 and connecting the door anti-fall bracket to the fixing base 5 with bolts 4. This avoids unnecessary stress accumulation or damage to the door body 2 itself. The fixing base 5, as an intermediate connector, provides a pre-set, stable installation benchmark for the anti-fall bracket, improving installation accuracy and simplifying the installation process. This switchgear can effectively support the anti-fall bracket, preventing the door body 2 from becoming loose, moving downwards, or even falling.

[0060] In some preferred embodiments, such as Figure 5 As shown, the fixing seat 5 is a U-shaped buckle with bending plates 51 on both sides. The fixing seat 5 is welded and fixed to the door body 2 by the bending plates 51.

[0061] Specifically, the two side bending plates 51 refer to the plate-like structure formed by bending the two sides of the fixing seat 5 outward or inward, and the U-shaped buckle refers to a U-shaped groove or protrusion structure formed on the fixing seat 5.

[0062] Specifically, the mounting base 5 is designed with U-shaped clips on both sides of the bent plates 51. The structure of the bent plates 51 provides additional rigidity and strength to the mounting base 5 and increases the contact area for welding with the door body 2, thus forming a more robust and stable connection base. This helps to distribute stress and reduce loosening of the connection due to long-term use or vibration, thereby enhancing the overall support stability of the anti-fall bracket. Simultaneously, the U-shaped clip design provides precise positioning and limiting for the installation of the anti-fall bracket, ensuring its correct and secure installation on the mounting base 5, and also increases the structural strength and deformation resistance of the mounting base 5. By providing a clear load-bearing and fixing interface, it further improves the reliability of the anti-fall bracket in supporting the door body 2 when the door body 2 is closed.
