Description

Technical Field

[0001] The invention belongs to the technical field of electrical equipment, and in particular relates to a distribution box rail assembly. Background Art

[0002] A distribution box is a device used to assemble electrical components such as switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet according to electrical wiring requirements to form a low-voltage power distribution device. Usually, the function of the distribution box is to distribute electricity to the next-level distribution point or each power point, that is, to distribute electrical energy to each power line as required. When installing electrical equipment such as circuit breakers and contactors, they are generally installed on the rails of the distribution box. In the prior art, most of the rails are fixed to the supporting structure at both ends at the same time. Even if it is a detachable connection method, there are many inconveniences in practical application. For example, patent CN220253865U-a distribution box rail assembly, both ends of its connecting plate are fixedly connected with U-shaped slot blocks, and the U-shaped slot blocks on each side and the strip plate need to be connected by bolts to maintain the stability of the connecting plate. In order to improve operating efficiency, it is necessary to improve the existing rail assembly. Summary of the invention

Thus, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0025] In the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0027] A distribution box rail assembly, such as Figures 1 to 7 As shown, it includes a fixed plate 1, and support structures 2 are symmetrically arranged on both sides of the fixed plate, and a plurality of snap-on plates 3 are detachably installed between the two support structures; usually, each snap-on plate is arranged horizontally. The support structure includes a support frame 4, the lower end of the support frame is slidably installed on a guide rail 5, the guide rail is slidably installed on the fixed plate, and a limiter is provided on the fixed plate at the extreme position corresponding to the guide rail, and a plurality of installation grooves 6 are arranged at intervals along the height direction on the support frame, and a storage groove 7 is provided at the bottom of the support frame, and each installation groove is connected by a vertical long groove 8, and a snap-on plate installation platform 9 is formed on both sides of the bottom of the installation groove.

[0028] The position and number of the clip-on plates can be configured as needed, and the remaining clip-on plates can be placed in the storage slot for storage. The two ends of the clip-on plates do not need to be fixed by bolts, and the operation is very simple. Of course, those skilled in the art can use limit pins and other components to fix one side of the clip-on plate to the support structure without fixing both ends of the clip-on plate by bolts. In actual application, even if the clip-on plate is not fixed to the support structure, it will not affect normal use, because the two ends of the clip-on plate installed in the installation slot will be constrained by the side panels of the distribution box and will not move arbitrarily to the two ends. Even if there is a certain lateral displacement, the maximum displacement, that is, the end of the clip-on plate will be against the inner wall surface of the side panel, and the distribution box will not move or shake frequently when in use, so the clip-on plate can ensure the required stability.

[0029] The clamping plate includes a mounting portion 10 and a clamping portion 11. The lower surface of the mounting portion is simultaneously fitted with the clamping portion mounting platforms on both sides. The clamping portion is located at the lower side of the mounting portion. In an optional embodiment, both ends of the clamping portion extend to the supporting structure respectively, so that the clamping portion is restricted by the two side walls of the long groove, and the clamping plate will not swing significantly. When the width of the long groove is closer to the thickness of the clamping portion, in fact, the long groove forms a good limiting effect on the clamping plate, and the stability during use is higher.

[0030] Usually, the mounting portion is arranged horizontally. The mounting portion and the clamping portion are an integrally formed structure. The storage space inside the storage slot is 2-5 times the size of the mounting slot. There are 2-8 clamping plates. When in use, the fixing plate is installed at the bottom of the distribution box, and the rail assembly (the supporting structure together with the clamping plate) can be pulled outward. Since the guide rail is slidably installed on the fixing plate, the end of the guide rail facing the door of the distribution box can extend out of the box 12, and the supporting structure can slide to the end of the guide rail (i.e., the outside of the box), which is very convenient for the installation of the clamping plate and the installation of electrical components on the clamping plate. After all installation operations are completed, the supporting structure can be pushed into the box until the supporting structure is pushed to the working position, and then the guide rail is limited by the limiting member to ensure that no sliding occurs between the guide rail and the fixing plate.

[0031] The limiting member includes a limiting pin, and a limiting hole can be set on the fixed plate. The lower end of the limiting pin (inserted on the guide rail) is inserted into the limiting hole, so that the guide rail and the fixed plate remain in a fixed state to limit the free sliding of the guide rail. Similarly, the support frame can also be limited as needed, for example, the limiting member passes through the through holes on the support frame and the guide rail at the same time, and the end of the limiting member is inserted into the limiting hole of the fixed plate. Since the use of a limiting pin to limit the relative movement between two components is an existing technology, those skilled in the art can also adopt a conventional design as long as the guide rail and the fixed plate can be fixed, which will not be repeated here.

[0032] The upper portion of the mounting groove is an arc-shaped structure, which maximizes the rigidity of the supporting structure and reduces stress concentration. Although the supporting structure is under less load during use, the structural design that reduces stress concentration can still extend the service life of the rail assembly to a certain extent. The mounting groove with an arc-shaped structure on the upper portion is more convenient for the installation of the clamping part.

[0033] The invention has a reasonable structural design, and the supporting structure can slide out of the box body of the distribution box, which is very convenient for installing the clip-on plates and electrical components. In addition, the position and number of the clip-on plates can be configured as needed, and the remaining clip-on plates can be placed in storage slots for storage. The two ends of the clip-on plates do not need to be fixed by bolts, which simplifies the operation and makes the construction work very convenient and efficient.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
