Description

Technical Field

[0001] This utility model relates to the field of distribution box guide rail technology, specifically a highly adaptable distribution box guide rail. Background Technology

[0002] Distribution box rails are standardized metal strips installed inside the box to fix modular electrical components. They are commonly made of galvanized steel or aluminum profiles, and the surface is often coated or perforated at the edges. Their core function is to provide a quick mounting reference for components such as circuit breakers and contactors. They achieve "one-plug-and-secure" by using spring clips on the back, ensuring the stability of electrical connections and safe distance between phases. In traditional distribution boxes, the rails for installing electrical components (such as air switches) are usually directly fixed to the back panel of the box with screws, and their installation position is fixed and cannot be adjusted.

[0003] In actual installation, manufacturing errors in the distribution box itself, tilted installation, or the need to adapt to existing hole positions during renovation projects often lead to difficulties in precisely aligning the guide rails horizontally, or the inability to fine-tune their fixed positions, causing inconvenience for wiring operations. Furthermore, the air switches on standard guide rails are only fixed by their own clips, which may be at risk of displacement under vibration or external force, and their densely packed terminals are usually exposed, posing a certain safety hazard. Therefore, existing technologies suffer from insufficient flexibility in guide rail installation within distribution boxes, a need to strengthen the stability of air switch positioning, and inadequate circuit protection measures.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a highly adaptable distribution box rail to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0005] The purpose of this invention is to provide a highly adaptable distribution box guide rail to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a highly adaptable distribution box guide rail, comprising:

[0007] Mounting plate;

[0008] The guide rail is adjustablely mounted on the mounting plate via a connecting assembly, and the guide rail is used to mount one or more air switches;

[0009] At least one positioning element is slidably sleeved on the guide rail and can be fixed to a specific position on the guide rail by a locking mechanism, for limiting the installation position of the air switch on the guide rail;

[0010] Cover plate, used to cover the wiring;

[0011] The mounting plate is provided with a first plug-in part, and the cover plate is provided with a second plug-in part that cooperates with the first plug-in part. The cover plate is detachably installed on the mounting plate through the cooperation of the first plug-in part and the second plug-in part, and the cover plate is provided with a slot for passing through the wire.

[0012] Specifically, the adjustable connection between the guide rail and the mounting plate enables multi-directional flexible adjustment of the installation position within the distribution box. The sliding and locking of the positioning components ensures the stability and precision of the air switch's layout on the guide rail. Furthermore, the convenient plug-in and slot design of the cover plate provides centralized and safe shielding protection for the circuits, thereby comprehensively improving the adaptability, reliability, and operational and maintenance safety of the components installed within the distribution box.

[0013] Preferably, the connection component includes:

[0014] At least one locking slot is provided on the mounting plate;

[0015] Multiple oblong holes are formed on the guide rail;

[0016] Locking bolts, inserted into locking grooves and oblong holes, press and fix the guide rail to the mounting plate.

[0017] Specifically, the locking groove and the oblong hole work together, and the locking bolts are used for fixing, allowing the guide rail to be infinitely adjustable in both longitudinal and lateral directions on the mounting plate. This not only effectively compensates for installation errors or deformation of the distribution box itself, but also allows for fine adjustment of the tilt of a single guide rail after it is fixed, thus ensuring that the air switch installed on it always remains level. At the same time, the multiple oblong holes on the guide rail provide a variety of connection points for the locking bolts, significantly enhancing the stability and adaptability of the connection between the guide rail and the mounting plate. The entire connection structure can be achieved using only conventional locking bolts, combining the advantages of easy adjustment and reliable connection.

[0018] Preferably, the length direction of the locking groove is perpendicular to the length direction of the oblong hole.

[0019] Preferably, the length direction of the locking groove is parallel to the width direction of the mounting plate, and the length direction of the oblong hole is parallel to the length direction of the guide rail.

[0020] Specifically, by setting the length direction of the locking groove and the length direction of the oblong hole to be perpendicular to each other, and further defining that the locking groove is parallel to the width direction of the mounting plate and the oblong hole is parallel to the length direction of the guide rail, the structure clearly defines that the guide rail has two decoupled independent adjustment dimensions relative to the mounting plate. This allows the guide rail to move up and down along the width direction of the mounting plate to adapt to the vertical space of the distribution box, and to slide flexibly horizontally along its own length direction to accurately align the installation point. More importantly, when the mounting plate is not completely horizontal due to box deformation or installation errors, this orthogonal slot design allows for slight changes in the installation tilt angle of the guide rail by adjusting the different positions of the locking bolts in the slot, thereby ensuring that the air switch installed on it can ultimately present a neat horizontal state, greatly improving the error tolerance of on-site installation and the standardization of the final product.

[0021] Preferably, a single guide rail is connected to the mounting plate by at least two locking bolts.

[0022] Specifically, by using at least two locking bolts to connect a single guide rail to the mounting plate, a stable multi-point fixing constraint is further formed on the basis of a two-dimensional adjustment system consisting of two mutually perpendicular locking grooves and oblong holes. This not only effectively prevents the guide rail from rotating or loosening around a single point due to vibration or load during long-term use, ensuring the long-term reliability of the connection, but also significantly enhances its ability to resist the torsional torque generated by the installation of multiple air switches and wiring operations by distributing multiple fastening points along the length of the guide rail. This ensures the overall rigidity and stability of the entire mounting assembly, allowing the aforementioned position and tilt adjustment functions to be realized on a stable basis.

[0023] Preferably, the locking mechanism is a positioning screw, and the positioning part has a screw hole that is threaded to the positioning screw. Tightening the positioning screw causes its end to press against the guide rail, thereby fixing the positioning part to the guide rail.

[0024] Specifically, by using a positioning screw as the locking mechanism and forming a threaded engagement with the screw hole on the positioning component, the sliding and locking operation of the positioning component on the guide rail becomes extremely direct and efficient. Tightening the positioning screw causes its end to directly press against the side wall of the guide rail, utilizing the self-locking property of the thread and friction to achieve a firm fixation. This structure not only provides reliable locking and effectively prevents the positioning component from shifting during vibration, but also makes unlocking and readjustment convenient and quick, requiring only the loosening of the screw. This provides great operational convenience for the layout adjustment and precise positioning of the air switch. At the same time, the locking mechanism is simple in structure, low in cost, and stable in performance.

[0025] Preferably, the first insertion portion is a slot formed on the mounting plate, and the second insertion portion is an insertion protrusion formed on the cover plate.

[0026] Preferably, the cover plate has an L-shaped cross-section.

[0027] Specifically, by setting the first plug-in part as a slot on the mounting plate and the second plug-in part as a plug-in protrusion on the cover plate, combined with the L-shaped cross-section of the cover plate, the cover plate can be quickly installed and removed through a simple plug-in action, greatly improving the convenience of wiring and subsequent maintenance. The L-shaped cover plate not only makes full use of the space between the edge of the mounting plate and the wiring side of the air switch, providing effective shielding and protection for the lines below, but its unique cross-sectional shape also gives it higher structural strength, making it better able to resist accidental collisions. The cooperation between the plug-in protrusion and the slot constitutes a reliable guiding and positioning mechanism, ensuring the stability and neat appearance of the cover plate after installation.

[0028] Preferably, the mounting plate has multiple parallel locking slots to provide multiple optional connection positions for a single guide rail.

[0029] Specifically, by creating multiple parallel locking slots on the mounting plate, several optional connection positions are provided for the installation and fixing of a single guide rail. This allows the guide rail to flexibly select the most suitable installation point for fixing based on the actual spatial layout inside the distribution box, cable routing, or interference from other components, greatly enhancing the spatial adaptability of the entire distribution box guide rail system. At the same time, the multiple locking slots make it possible to achieve a more optimized force distribution. Users can choose a combination of locking slots that are far apart to install the same guide rail, thereby significantly improving the vibration resistance and overall structural stability of the guide rail and the air switch it carries during long-term operation.

[0030] Compared with the prior art, this utility model provides a highly adaptable distribution box guide rail, which has the following beneficial effects:

[0031] It solves the problems of poor installation flexibility, unstable component fixing, and exposed wiring risks in traditional distribution box rail systems. Through its innovative adjustable connection structure, the rail can be precisely adjusted and leveled in multiple dimensions on the mounting plate, greatly compensating for errors in box manufacturing and installation, and significantly improving installation efficiency and finished product standardization. Its unique sliding locking positioning mechanism provides a solid limit guarantee for the air switch, effectively preventing displacement hazards caused by vibration or operation, and enhancing the long-term stability and safety of the system. At the same time, the convenient plug-in L-shaped protective cover design realizes centralized storage and effective isolation of the dense wiring in front of the air switch, which not only greatly reduces the risk of personnel accidentally touching live parts, but also makes the internal layout of the box more neat and standardized. Ultimately, they constitute a highly adaptable distribution box rail solution that is more flexible in installation, more reliable in operation, and safer in maintenance. Attached Figure Description

[0050] At least one positioning element 40 is slidably sleeved on the guide rail 20 and can be fixed to a specific position on the guide rail 20 by a locking mechanism, for limiting the installation position of the air switch 30 on the guide rail 20;

[0051] Cover plate 50, used to cover the wiring;

[0052] The mounting plate 10 is provided with a first plug-in part, and the cover plate 50 is provided with a second plug-in part that cooperates with the first plug-in part. The cover plate 50 is detachably installed on the mounting plate 10 through the cooperation of the first plug-in part and the second plug-in part, and the cover plate 50 is provided with a slot 510 for passing through the wire.

[0053] Specifically, the adjustable connection between the guide rail 20 and the mounting plate 10 enables multi-directional flexible adjustment of the installation position inside the distribution box. The sliding and locking of the positioning component 40 ensures the stable and precise layout of the air switch 30 on the guide rail 20. The convenient plug-in of the cover plate 50 and the slot design 510 provide centralized and safe shielding protection for the circuit, thereby improving the adaptability, reliability, and safety of operation and maintenance of the components installed inside the distribution box.

[0054] Preferably, the connection component includes:

[0055] At least one locking slot 110 is provided on the mounting plate 10;

[0056] Multiple oblong holes 210 are provided on the guide rail 20;

[0057] Locking bolts 60 are inserted into locking grooves 110 and oblong holes 210 to press and fix guide rail 20 onto mounting plate 10.

[0058] Specifically, by engaging the locking groove 110 with the oblong hole 210 and securing it with the locking bolt 60, the guide rail 20 can be infinitely adjusted in both longitudinal and lateral directions on the mounting plate 10. This not only effectively compensates for installation errors or deformation of the distribution box itself, but also allows for fine adjustment of the tilt of a single guide rail 20 after it is fixed, ensuring that the air switch 30 installed on it remains level and symmetrical. At the same time, the multiple oblong holes 210 on the guide rail 20 provide a variety of connection points for the locking bolt 60, significantly enhancing the stability and adaptability of the connection between the guide rail 20 and the mounting plate 10. The entire connection structure can be achieved using only conventional locking bolts 60, combining the advantages of easy adjustment and reliable connection.

[0059] Preferably, the length direction of the locking groove 110 is perpendicular to the length direction of the oblong hole 210.

[0060] Preferably, the length direction of the locking groove 110 is parallel to the width direction of the mounting plate 10, and the length direction of the oblong hole 210 is parallel to the length direction of the guide rail 20.

[0061] Specifically, by setting the length direction of the locking groove 110 and the length direction of the oblong hole 210 to be perpendicular to each other, and further defining that the locking groove 110 is parallel to the width direction of the mounting plate 10 and the oblong hole 210 is parallel to the length direction of the guide rail 20, the structure clearly defines that the guide rail 20 has two mutually decoupled independent adjustment dimensions relative to the mounting plate 10. This allows the guide rail 20 to move up and down along the width direction of the mounting plate 10 to adapt to the vertical space of the distribution box, and to slide flexibly horizontally along its own length direction to accurately align the installation point. More importantly, when the mounting plate 10 is not completely horizontal due to box deformation or installation errors, this orthogonal groove design allows for slight changes in the installation tilt angle of the guide rail 20 by adjusting the different positions of the locking bolt 60 in the groove, thereby ensuring that the air switch 30 installed on it can ultimately present a neat horizontal state, greatly improving the error tolerance of on-site installation and the standardization of the final product.

[0062] Preferably, a single guide rail 20 is connected to the mounting plate 10 by at least two locking bolts 60.

[0063] Specifically, by using at least two locking bolts 60 to connect a single guide rail 20 to the mounting plate 10, a stable multi-point fixing constraint is further formed on the basis of the two-dimensional adjustment system composed of two mutually perpendicular locking grooves 110 and oblong holes 210. This not only effectively prevents the guide rail 20 from rotating or loosening around a single point due to vibration or load during long-term use, ensuring the long-term reliability of the connection, but also significantly enhances its ability to resist the torsional torque generated by the installation of multiple air switches 30 and wiring operations by distributing multiple fastening points along the length of the guide rail 20. This ensures the overall rigidity and stability of the entire mounting assembly, enabling the aforementioned position and tilt adjustment functions to be realized on a stable basis.

[0064] Preferably, the locking mechanism is a positioning screw 410. The positioning member 40 has a screw hole that is threaded to the positioning screw 410. Tightening the positioning screw 410 causes its end to press against the guide rail 20, thereby fixing the positioning member 40 to the guide rail 20.

[0065] Specifically, by using a positioning screw 410 as a locking mechanism and forming a threaded engagement with the screw hole on the positioning member 40, the sliding and locking operation of the positioning member 40 on the guide rail 20 becomes extremely direct and efficient. Tightening the positioning screw 410 so that its end directly presses against the side wall of the guide rail 20, the self-locking characteristic of the thread and friction are used to achieve a firm fixation. This structure not only locks reliably and effectively prevents the positioning member 40 from shifting during vibration, but also unlocks and readjusts quickly and easily, requiring only the screw to be loosened. This provides great operational convenience for the layout adjustment and precise positioning of the air switch 30.

[0066] Preferably, the first insertion portion is a slot 120 formed on the mounting plate 10, and the second insertion portion is an insertion protrusion 520 formed on the cover plate 50.

[0067] Preferably, the cover plate 50 has an L-shaped cross-section.

[0068] Specifically, by setting the first plug-in part as a slot 120 on the mounting plate 10 and the second plug-in part as a plug-in protrusion 520 on the cover plate 50, combined with the L-shaped cross-section of the cover plate 50, the cover plate 50 can be quickly installed and removed through simple plug-in actions, greatly improving the convenience of wiring and subsequent maintenance.

[0069] Preferably, the mounting plate 10 has multiple parallel locking slots 110 to provide multiple optional connection positions for a single guide rail 20.

[0070] Specifically, by opening multiple parallel locking slots 110 on the mounting plate 10, multiple optional connection positions are provided for the installation and fixing of a single guide rail 20. This allows the guide rail 20 to flexibly select the most suitable installation point for fixing according to the actual spatial layout inside the distribution box, cable routing, or interference from other components, greatly enhancing the spatial adaptability of the entire distribution box guide rail system. At the same time, the setting of multiple locking slots 110 makes it possible to achieve a more optimized force distribution. Users can choose to combine locking slots 110 that are far apart to install the same guide rail 20, thereby significantly improving the vibration resistance and overall structural stability of the guide rail 20 and the air switch 30 it carries during long-term operation.

[0071] Working principle: During installation, the guide rail 20 is first initially connected to the mounting plate 10 by passing the locking bolt 60 through the locking groove 110 on the mounting plate 10 and the oblong hole 210 on the guide rail 20 itself. By utilizing the adjustment freedom provided by the mutually perpendicular locking groove 110 and oblong hole 210, the horizontal and vertical position and even the tilt of the guide rail 20 on the mounting plate 10 are adjusted. After adjustment, the locking bolt 60 is tightened to complete the final fixation. Then, the air switch 30 is snapped onto the guide rail 20, and the positioning piece 40 is slid to the appropriate position on both sides of the air switch 30 as needed. The positioning screw 410 is tightened to make it press against the guide rail 20, thereby firmly limiting the air switch 30. After the wiring is completed, the insertion protrusion 520 of the cover plate 50 is aligned with the slot 120 on the mounting plate 10 and inserted, so that the wire is introduced into its internal space from the slot 510 of the L-shaped cover plate 50, realizing the neatness and safety protection of the wire.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
