Detailed Implementation

[0024] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0026] Distribution boxes (or distribution cabinets) are devices in a power system used for distributing, controlling, protecting, and monitoring electrical energy. They are typically installed in buildings, factories, computer rooms, and other locations to distribute electrical energy from the main power source to various electrical devices or circuits. Guide rails are a standardized mounting structure inside distribution boxes or cabinets, usually made of metal (such as steel or aluminum), used to fix and install various electrical equipment, such as air switches, residual current circuit breakers, contactors, relays, etc. The design of the guide rails allows for quick and easy installation and disassembly of these devices, facilitating maintenance and replacement.

[0027] When electrical devices such as air switches and residual current circuit breakers are installed on DIN rails, they are usually fixed to the rails with clips on the back. However, there are technical problems such as complicated operation and difficult disassembly and installation when installing and removing them on the DIN rails.

[0028] The following is in conjunction with the accompanying drawings in the instruction manual. Figures 1-5 The guide rail fixing device is described in detail.

[0029] To address the aforementioned technical problems, this application provides a guide rail fixing device that can be quickly installed or removed from the guide rail and is easy to operate.

[0030] This application provides a guide rail fixing device, comprising: a support plate 1, including a first end 11 and a second end 12 disposed opposite to each other in a first direction; a first locking member 2, disposed at the first end 11, forming a first groove with the support plate 1, the opening of the first groove facing the second end 12, and the first groove having a preset depth in the first direction; a second locking member 3, disposed at the second end 12, forming a second groove with the support plate 1, the opening of the second groove facing the first end 11, and the second groove having a preset depth in the first direction; the first locking member 2 is provided with a telescopic member 24 fixed to the support plate 1 for adjusting the depth of the first groove in the first direction, and / or, the second locking member 3 is provided with a telescopic member 24 fixed to the support plate 1 for adjusting the depth of the second groove in the first direction.

[0031] Specifically, by enabling at least one of the first locking component 2 and the second locking component 3 to extend and retract, the depth of the first groove and at least one of the second grooves in the first direction can be adjusted to ensure that the guide rail can be firmly and accurately fixed to the support plate 1. This adjustment capability reduces trial and error and adjustment time during installation, improving installation efficiency. The first locking component 2 is provided with a telescopic component 24 fixed to the support plate 1 for adjusting the depth of the first groove in the first direction, and / or the second locking component 3 is provided with a telescopic component 24 fixed to the support plate 1 for adjusting the depth of the second groove in the first direction. The telescopic component 24 adjusts the length of at least one of the first locking component 2 and the second locking component 3 by its own extension and retraction, thereby adjusting the depth of the first groove and / or the second groove, so that the guide rail fixing device can adapt to guide rails of different sizes. This means that there is no need to design different fixing devices for each size of guide rail, thereby improving the versatility and flexibility of the device. Since the depth of the first groove and / or the second groove can be adjusted according to the size of the guide rail, the contact between the guide rail and the support plate 1 is tighter, reducing shaking or loosening caused by size mismatch. This enhances the stability of the entire system and ensures the reliability of the guide rail during long-term use. The guide rail fixing device is highly adaptable and versatile, reducing the number of different fixing devices that need to be purchased for different guide rail sizes, thereby reducing inventory and procurement costs.

[0032] In some optional embodiments, the first locking component 2 is provided with a telescopic component 24 fixed to the support plate 1 for adjusting the depth of the first groove in the first direction; or, the second locking component 3 is provided with a telescopic component 24 fixed to the support plate 1 for adjusting the depth of the second groove in the first direction.

[0033] Specifically, the first locking component 2 is telescopic, while the second locking component 3 is not, allowing the depth of the first groove to be adjustable, while the depth of the second groove is fixed. Alternatively, the second locking component 3 is telescopic, while the first locking component 2 is not, allowing the depth of the second groove to be adjustable, while the depth of the first groove is fixed. Only the depth of the first or second groove needs to be adjusted, making the device more flexible when dealing with guide rails of different sizes. It eliminates the need to adjust both locking components simultaneously, simplifying the adjustment process. Since only one of the first locking component 2 and the second locking component 3 needs to be telescopic, it reduces the number of complex mechanical structures and parts required, thereby lowering production costs. By adjusting one of the first locking component 2 and the second locking component 3 to fit the guide rail size, stable installation of the guide rail on the support plate 1 can be ensured. This design reduces wobbling or loosening caused by size mismatch, improving the stability and reliability of the entire system.

[0034] Furthermore, by enabling only one of the first locking component 2 and the second locking component 3 to extend or retract, the user only needs to operate one of these components to adjust the depth of the groove, thus simplifying the installation and disassembly steps, making operation more convenient, and reducing the complexity for the user. When installing or removing an air switch, the user only needs to adjust the extension or retraction of one of the first locking component 2 and the second locking component 3 to quickly complete the fixing or release, significantly improving efficiency. This is especially suitable for complex scenarios where switches are lined up on the rail, enabling quick replacement or maintenance of individual switches. This rail fixing device can be adaptably installed on air switches or residual current circuit breakers. For different models of air switches or residual current circuit breakers, only one of the first locking component 2 and the second locking component 3 needs to be adjusted to achieve a stable fixation, without the need to replace the fixing device. In distribution boxes or cabinets, the size of the rail may vary depending on the model; this design can flexibly accommodate these variations.

[0035] In some optional embodiments, the first locking component 2 is a locking plate disposed at the first end, the angle between the locking plate and the first end 11 is 0~180°, and the angle between the first end 11 and the support plate 1 is 0~180°; or, the second locking component 3 is a locking plate disposed at the second end 12, the angle between the locking plate and the second end 12 is 0~180°, and the angle between the second end 12 and the support plate 1 is 0~180°.

[0036] Specifically, the angle between the first locking component 2 and the first end 11 is 0~180°, and the angle between the first locking component 2 and the first end 11 can be selected as 60°, 90°, 120°, 135°, or 150°. The angle between the first end 11 and the support plate 1 is 0~180°, and the angle between the first end 11 and the support plate 1 can be selected as 60°, 90°, 120°, 135°, or 150°. The shape of the first groove can be adjusted according to the shape of the guide rail so that the first groove can fix the guide rail precisely, which has strong versatility. The angle between the second locking component 3 and the second end 12 is 0~180°, and the angle between the second locking component 3 and the second end 12 can be selected as 60°, 90°, 120°, 135°, or 150°. The angle between the second end 12 and the support plate 1 is also 0~180°, and the angle between the second end 12 and the support plate 1 can be selected as 60°, 90°, 120°, 135°, or 150°. The shape of the first groove can be adjusted according to the shape of the guide rail, so that the first groove can precisely fix the guide rail, which has strong versatility and can adapt to more scenarios. The angle between the first locking component 2 and the first end 11, and the angle between the first end 11 and the support plate 1 can be flexibly adjusted according to actual needs, reducing the possibility of operational errors. For non-standard guide rails or special installation environments, users can adjust the angle of the locking plate to ensure that the groove fits tightly with the guide rail.

[0037] In some optional embodiments, the first end 11 is a first protrusion extending away from the support plate 1, with an angle of 90° between the first protrusion and the support plate 1, and the locking plate extends in a first direction, with an angle of 90° between the locking plate and the first protrusion; or, the second end 12 is a second protrusion extending away from the support plate 1, with an angle of 90° between the second protrusion and the support plate 1, and the locking plate extends in a second direction, with an angle of 90° between the locking plate and the first protrusion.

[0038] Specifically, the angle between the first protrusion and the support plate 1 is 90°, the angle between the first locking component 2 and the first protrusion is 90°, forming a right-angle structure; the angle between the second protrusion and the support plate 1 is 90°, and the angle between the second locking component 3 and the second protrusion is 90°, forming a right-angle structure. The right-angle structure enhances the mechanical strength and rigidity of the fixing device. It effectively disperses external forces, preventing deformation or loosening of the device during installation or use. When installing electrical devices, the right-angle structure ensures tight contact between the groove and the guide rail, avoiding displacement caused by vibration or external forces. It is particularly suitable for high-current or high-load electrical devices, effectively preventing electrical faults caused by insecure fixing. The right-angle design makes the fixing device more compact, optimizing space utilization. In space-constrained distribution boxes or cabinets, this design reduces the space occupied by the fixing device, leaving more space for other equipment or lines. It is especially suitable for compact environments where switches are arranged on the guide rail, allowing for quick installation or removal of individual switches without affecting other equipment.

[0039] In some optional embodiments, the first locking component 2 is provided with a telescopic component 24 fixed to the support plate 1 for adjusting the depth of the first groove in the first direction, and the second locking component 3 is provided with a telescopic component 24 fixed to the support plate 1 for adjusting the depth of the second groove in the first direction.

[0040] Specifically, both the first locking component 2 and the second locking component 3 are telescopic, allowing the fixing device to adapt to guide rails of different sizes, shapes, or installation positions. For non-standard guide rails or special installation environments, users can adjust the telescopic state of the two locking components to ensure a tight fit between the grooves and the guide rail. It is compatible with various types of guide rails and has strong versatility. By adjusting the telescopic state of the first locking component 2 and the second locking component 3, users can more easily install or remove air switches or residual current circuit breakers from the guide rail. During installation, users can adjust the telescopic state of the first locking component 2 and the second locking component 3 according to the position and shape of the guide rail to align the first and second grooves with the guide rail, thus quickly completing the fixing. During disassembly, users only need to adjust the telescopic state of the first locking component 2 and the second locking component 3 to easily release the electrical device, avoiding the cumbersome operation of traditional methods that require forceful pushing and pulling or the use of tools. By adjusting the extension and retraction of the first locking component 2 and the second locking component 3, it can be ensured that the first and second grooves fit tightly against the guide rail, thereby improving the stability of the fixing device and preventing loosening. A stable fixation reduces displacement of the electrical device due to vibration or external forces during operation, improving safety. Both locking components are extendable, allowing users to flexibly adjust them according to actual needs, reducing the possibility of operational errors.

[0041] In some optional embodiments, the first locking component 2 and the second locking component 3 have the same structure. The first locking component 2 includes a fixing element 21, a first lever 22, a second lever 23 and a telescopic component 24. The fixing element 21 is provided with a groove that is recessed from one end to the other end. One end of the telescopic component 24 is fixed to the bottom of the groove and the other end is fixed to the support plate 1. The bottom of the groove faces the opening end of the groove. The first lever 22 and the second lever 23 are rotatably connected to the fixing element 21 on both sides of the groove. The first lever 22 and the second lever 23 are fixedly connected to the support plate 1.

[0042] Specifically, in use, force can be applied to the side of the fixing element 21 away from the bottom ends of the first lever 22 and the second lever 23, with the force applied in the direction of the first lever 22 and the second lever 23. The fixing element 21 moves upward, compressing the telescopic component 24. The first lever 22 and the second lever 23 rotate around the fixing element 21, thereby causing the first lever 22 and the second lever 23 to gradually shorten in the first direction. The telescopic component 24 is also compressed, thereby shortening the length of the first locking component 2 or the second locking component 3, thus reducing the depth of the first groove and the second groove, allowing the guide rail to be disassembled. When the force applied to the fixing element 21 is no longer applied, the telescopic component 24 returns to its original position, and the first lever 22 and the second lever 23 also return to their original positions. The operation is simple and convenient. The operator only needs to apply upward force to the fixing element 21 to adjust the length of the first locking component 2 and / or the second locking component 3, thereby adjusting the depth of the first groove and the second groove, thus completing the installation and disassembly of the guide rail.

[0043] In some optional embodiments, the first lever 22 and the second lever 23 are arc-shaped, with the inwardly concave side of the first lever 22 facing the second lever 23 and the inwardly concave side of the second lever 23 facing the first lever 22. A locking head 6 is provided at the end of the first lever 22 and the second lever 23 away from the fixing element 21.

[0044] Specifically, the arc-shaped levers can evenly distribute the clamping force, avoiding localized stress concentration and reducing wear on the guide rail and fixing device. The tight contact between the locking head 6 and the guide rail effectively prevents displacement of the equipment during operation due to vibration or external force, improving safety. It is especially suitable for high-current or high-load electrical equipment, effectively preventing electrical faults caused by insecure fixing. The first lever 22 and the second lever 23 are respectively connected to the fixing element 21 via the rotating shaft 4, and the first lever 22 and the second lever 23 are respectively connected to the support plate 1 via the fixing shaft 5. When force is applied to the fixing element 21, the first lever 22 and the second lever 23 will rotate around the rotating shaft 4 and the fixing shaft 5, and the locking head 6 will move until it is no longer in contact with the guide rail, thus allowing the guide rail to be removed. After the fixing element 21 is released, the locking head 6 will automatically spring back to its original position, and the locking head 6 will be in tight contact with the guide rail, completing the fixing.

[0045] In some optional embodiments, the telescopic component 24 includes a first limiting plate 241, a spring 242, and a second limiting plate 243. One end of the first limiting plate 241 is fixed to the support plate 1, and the second limiting plate 243 is disposed at the bottom of the groove of the fixing element 21. The spring 242 is connected to the first limiting plate 241 and the second limiting plate 243 respectively.

[0046] Specifically, the telescopic component 24 provides continuous elastic force by connecting the first limiting plate 241 and the second limiting plate 243 via spring 242, ensuring the locking component remains stable after installation. The elastic force of spring 242 ensures tight contact between the locking head 6 and the guide rail, preventing loosening due to vibration or external force. The limiting effect of the first limiting plate 241 and the second limiting plate 243 prevents excessive compression or stretching of spring 242, ensuring the stability and reliability of the telescopic component 24. This is particularly suitable for high-current or high-load electrical equipment, effectively preventing electrical faults caused by insecure fixing. Through the elastic force of spring 242, the user can easily adjust the telescopic state of the first locking component 2 and / or the second locking component 3, thereby simplifying installation and disassembly operations.

[0047] On the other hand, this application provides an electrical device including the guide rail fixing device mentioned in any of the above.
