Description

Technical Field

[0001] This utility model relates to the technical field of fire-resistant busbar trunking connection equipment, and in particular to a deformation-resistant fire-resistant busbar trunking. Background Technology

[0002] In scenarios such as industrial power distribution and high-rise building power supply, the stable operation of fire-resistant busbar trunking depends on the core connecting component—the busbar trunking connector, whose performance directly determines the safety and reliability of the overall power transmission system.

[0003] However, existing fire-resistant busbar connectors have defects in terms of deformation resistance and structural stability in practical applications. The connector body of traditional fire-resistant busbars mostly adopts a single shell structure, relying solely on the rigidity of its own material to resist deformation caused by external impact or temperature changes. It lacks additional reinforcement and support mechanisms. During long-term use, the connector body may experience deformation problems such as local bending and misalignment due to factors such as building settlement, equipment vibration, and cable self-weight pulling. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. Traditional fire-resistant busbar trunking connectors often use a single shell structure, relying solely on the rigidity of their own materials to resist deformation caused by external impacts or temperature changes. They lack additional reinforcement and support mechanisms. During long-term use, due to factors such as building settlement, equipment vibration, and cable self-weight pulling, the connector body may experience deformation problems such as local bending and misalignment. This invention provides a deformation-resistant fire-resistant busbar trunking.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a deformation-resistant fire-resistant busbar trunking, comprising a busbar trunking connector body, an extension plate fixedly connected to the top of the busbar trunking connector body, a first connecting plate fixedly connected to one side of the extension plate, a connecting post fixedly connected to one side of the first connecting plate, a first horizontal plate fixedly connected to one side of the first connecting plate, a connecting clamp slidably connected to one end of the connecting post, a second connecting plate fixedly connected to the outer surface of the connecting clamp, a movable plate fixedly connected to one end of the second connecting plate, a U-shaped support plate slidably connected to one side of the movable plate, and a second horizontal plate fixedly connected to one side of the U-shaped support plate.

[0006] In a preferred embodiment, the outer surface of the expansion plate is provided with a connection hole, and the inner wall of the connection hole is slidably connected to the outer surface of the connecting post.

[0007] In a preferred embodiment, the outer surface of the movable plate is provided with a movable hole, and the inner wall of the movable hole is slidably connected to the outer surface of the U-shaped support plate.

[0008] In a preferred embodiment, a rotating hole is provided on the outer surface of the second horizontal plate, and a support member is provided on one side of the rotating hole.

[0009] In a preferred embodiment, the support includes a rotating top rod, and a rotating column is fixedly connected to one side of the rotating top rod. The outer surface of the rotating column is rotatably connected to the inner wall of the rotating hole.

[0010] In a preferred embodiment, an external threaded frame is rotatably connected to the outer surface of the rotating column, one side of the external threaded frame is fixedly connected to the outer surface of the second horizontal plate, and a nut is threadedly connected to the outer surface of the external threaded frame.

[0011] In a preferred embodiment, a limiting port is provided at one end of the connecting column, and the inner wall of the limiting port is slidably connected to the inner wall of the connecting hoop.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This utility model, by setting an extension plate and connecting holes, facilitates the installation of additional reinforcing structures to enhance the deformation resistance. The first connecting plates are symmetrically distributed vertically and horizontally, totaling four. There are two first horizontal plates at the top and two at the bottom, which facilitates the fixed connection of the two first connecting plates at the top and bottom. The connecting posts facilitate the connection of the reinforcing components on both sides of the busbar connector body. The limiting ports and connecting clamps engage with each other to prevent the connecting posts from disengaging from the connecting holes on both sides. The limiting ports are set on all four connecting posts, and the openings all face inward. The moving holes and U-shaped support plates allow the moving plates to be pushed to both sides under pressure, thereby locking the connecting clamps into the limiting ports.

[0021] 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.

[0022] Example 1

[0023] like Figure 1-4 As shown, this utility model provides a technical solution: a deformation-resistant fire-resistant busbar trunking, including a busbar trunking connector body 1, an extension plate 2 fixedly connected to the top of the busbar trunking connector body 1, a first connecting plate 3 fixedly connected to one side of the extension plate 2, a connecting post 4 fixedly connected to one side of the first connecting plate 3, a first horizontal plate 5 fixedly connected to one side of the first connecting plate 3, a connecting clamp 6 slidably connected to one end of the connecting post 4, a second connecting plate 7 fixedly connected to the outer surface of the connecting clamp 6, and a movable plate 8 fixedly connected to one end of the second connecting plate 7. A U-shaped support plate 9 is slidably connected to one side of the movable plate 8, and a second horizontal plate 10 is fixedly connected to one side of the U-shaped support plate 9. A connecting hole is opened on the outer surface of the extension plate 2, and the inner wall of the connecting hole is slidably connected to the outer surface of the connecting column 4. A moving hole is opened on the outer surface of the movable plate 8, and the inner wall of the moving hole is slidably connected to the outer surface of the U-shaped support plate 9. A rotating hole is opened on the outer surface of the second horizontal plate 10, and a support member 11 is provided on one side of the rotating hole. A limit port is opened at one end of the connecting column 4, and the inner wall of the limit port is slidably connected to the inner wall of the connecting hoop 6.

[0024] In this embodiment, by setting the expansion plate 2 and the connecting holes, it is convenient to install additional reinforcement structures to increase the deformation resistance effect. Four first connecting plates 3 are symmetrically arranged in the upper, lower and left, and two first horizontal plates 5 are arranged in the upper and lower, so as to fix the two first connecting plates 3 at the upper and lower ends. The connecting post 4 is convenient to connect the reinforcement components on both sides of the busbar connector body 1. The locking of the limiting port and the connecting clamp 6 prevents the connecting post 4 from falling out of the connecting holes on both sides. The limiting port is set in all four connecting posts 4 and the opening faces inward. The moving hole and the U-shaped support plate 9 allow the moving plate 8 to be pushed to both sides by pressure, thereby locking the connecting clamp 6 in the limiting port.

[0025] The second connecting plate 7 and the first connecting plate 3 on the other side are respectively provided, and there are four of each. The second horizontal plate 10 is also provided in two. The C-shaped support plates 9 on both sides are connected together. The support member 11 is provided to apply pressure to the moving plates 8 on both sides, so that the connecting hoop 6 is locked in the limiting port.

[0026] Example 2

[0027] like Figure 4 As shown, the support member 11 includes a rotating push rod 111, a rotating column 112 is fixedly connected to one side of the rotating push rod 111, the outer surface of the rotating column 112 is rotatably connected to the inner wall of the rotating hole, an external threaded frame 113 is rotatably connected to the outer surface of the rotating column 112, one side of the external threaded frame 113 is fixedly connected to the outer surface of the second horizontal plate 10, and a nut 114 is threadedly connected to the outer surface of the external threaded frame 113.

[0028] In this embodiment, the rotating top rod 111 can be driven to rotate by the rotating column 112, thereby causing the two ends of the rotating top rod 111 to press against the moving plates 8 on both sides and slide inside the U-shaped support plate 9, achieving the effect of locking the connecting hoop 6 in the limiting port. By setting the external thread frame 113 and the nut 114, when the nut 114 is screwed into the external thread frame 113, pressure is applied to the rotating column 112, making it difficult for the rotating column 112 and the rotating top rod 111 to rotate, and always supporting them on one side of the moving plate 8. The support member 11 is set in the second horizontal plate 10 at both the upper and lower ends to increase the supporting force on the moving plate 8.

[0029] Working principle:

[0030] like Figure 1-4As shown, in the actual installation process, the busbar connector body 1 is first initially connected to the external busbar. Then, the connecting post 4 is inserted through the connecting hole on the expansion plate 2, so that the first connecting plates 3 on both sides form a transverse support frame through the connecting post 4. Next, the rotating push rod 111 in the support member 11 is rotated so that its two ends abut against the moving plates 8 on both sides, pushing the four connecting clamps 6 to the limiting port of the connecting post 4. Then, the nut 114 is rotated so that it moves inward along the external thread frame 113. The angle of the rotating push rod 111 is fixed by pressing the rotating post 112, thereby using the rotating push rod 111 to apply continuous pressure to the moving plate 8. The outward supporting force further ensures the stable engagement of the connecting hoop 6 and the limiting port. During this process, the moving plate 8 slides along the track of the U-shaped support plate 9 until the connecting hoop 6 is fully engaged in the limiting port, thus fixing the connecting column 4 and the expansion plate 2. In addition, during this process, the first horizontal plate 5 and the second horizontal plate 10 respectively provide longitudinal reinforcement to the upper and lower sets of first connecting plates 3 and U-shaped support plates 9. Together with the lateral support of the connecting column 4 and the support member 11, the busbar connector body 1 can offset the deformation stress through the multi-directional force dispersion structure when subjected to external impact or high temperature deformation, thereby improving the overall deformation resistance and fire resistance stability.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
