Description

Technical Field

[0001] This utility model relates to the field of busbar trunking connection technology, and in particular to a busbar trunking with stable connection. Background Technology

[0002] Busbar trunking is an enclosed metal device composed of copper and aluminum busbar columns. It is used to distribute larger power to various components of a distributed system and has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects.

[0003] Due to limitations in busbar trunking production, connections are often required in actual use. Currently, most busbar trunking connection structures involve connecting the internal busbars via connectors, and then fixing connecting plates to the tops of the busbar trunking on both sides with bolts. This allows the tops of the two busbar trunking sections to be connected as a whole. During use, the nuts on the bolts need to be tightened or loosened to open or close the busbar trunking. Fixing the connecting plates to the tops of the busbar trunking on both sides with bolts requires aligning the mounting holes, which is cumbersome and prolongs installation time. Furthermore, if the bolts become loose, the connecting plates are prone to connection instability. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology. When fixing the connecting plate to the top of the busbar trough on both sides with bolts, it is necessary to align the mounting holes for positioning, which is cumbersome. This utility model provides a busbar trough with stable connection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a stable busbar trunking, comprising a busbar trunking body, the busbar trunking body including a shell, the top of the shell having a connection port, a first fixing frame provided on one side of the connection port, the first fixing frame including a mounting frame, both ends of the mounting frame being fitted to the inner wall of the connection port, a pressing port provided on one side of the mounting frame, a second fixing frame provided on one side of the mounting frame, the second fixing frame including a combination frame, a fixing component provided on the outer surface of the combination frame, the fixing component including a surrounding frame, the inner wall of the surrounding frame being fitted to the outer surface of the combination frame, a fixing foot provided at the bottom of the surrounding frame, baffles fixedly connected to both sides of the fixing foot, a support rod fixedly connected to the outer surface of the fixing foot, and a spring movably connected to the outer surface of the support rod.

[0006] In a preferred embodiment, the outer surface of the combination frame is provided with a fixing hole, the outer surface of the surrounding frame is provided with a knob, the outer surface of the knob is fixedly connected with a connecting post, the top of the surrounding frame is provided with a circular hole, and the inner wall of the circular hole and the inner wall of the connecting post are slidably connected.

[0007] In a preferred embodiment, a limiting foot is fixedly connected to the bottom of the connecting column, and the outer surface of the limiting foot is slidably connected to the inner wall of the fixing hole.

[0008] In a preferred embodiment, the bottom of the enclosure frame is provided with a connecting groove, and the top of the connecting groove is provided with a support groove.

[0009] In a preferred embodiment, the top of the spring is fixedly connected to the inner wall of the connecting groove, and the bottom of the spring is fixedly connected to the outer surface of the fixing foot.

[0010] In a preferred embodiment, the inner wall of the support groove and the outer surface of the support rod are slidably connected.

[0011] In a preferred embodiment, the outer surface of the fixing foot is slidably connected to the inner wall of the extrusion port.

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

[0013] This utility model features a connection port for engaging with the mounting frame and the assembly frame. Both ends of the mounting frame and the assembly frame have borders that engage with the connection port, thus connecting the main bodies of the busbar trunking on both sides. A fixing component is provided to secure the assembly frame and the mounting frame tightly against the top of the main bodies of the busbar trunking on both sides, with the surrounding frame attached to the surface of the assembly frame. There is an opening on one side of the extrusion port, through which the fixing foot is placed into the extrusion port using the surrounding frame. The support rod supports the extension and contraction of the spring. The baffle moves down with the fixing foot but always covers one side of the space between the surrounding frame and the fixing foot, thus preventing the spring from being exposed on the surface and accidentally damaged. The innermost extrusion port engages with the outer surface of the fixing foot to prevent the fixing foot from moving due to the tension of the spring. Attached Figure Description

[0022] 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.

[0023] Example 1

[0024] like Figure 1-5As shown, this utility model provides a technical solution: a stable busbar trunking, including a busbar trunking body 1, the busbar trunking body 1 including a housing 101, a connection port 102 opened on the top of the housing 101, a first fixing frame 2 provided on one side of the connection port 102, the first fixing frame 2 including a mounting frame 201, both ends of the mounting frame 201 are attached to the inner wall of the connection port 102, a compression port 202 opened on one side of the mounting frame 201, a second fixing frame 3 provided on one side of the mounting frame 201, the second fixing frame 3 including a combination frame 301, a fixing component 4 provided on the outer surface of the combination frame 301, the fixing component 4 including a surrounding frame 401, the inner wall of the surrounding frame 401 being attached to the combination frame 301. The outer surface of frame 301 is surrounded by a fixed foot 402 at the bottom of frame 401. Both sides of the fixed foot 402 are fixedly connected to baffles 403. The outer surface of the fixed foot 402 is fixedly connected to a support rod 404. The outer surface of the support rod 404 is movably connected to a spring 405. The bottom of the surrounding frame 401 is provided with a connecting groove 406. The top of the connecting groove 406 is provided with a support groove 407. The top of the spring 405 is fixedly connected to the inner wall of the connecting groove 406. The bottom of the spring 405 is fixedly connected to the outer surface of the fixed foot 402. The inner wall of the support groove 407 and the outer surface of the support rod 404 are slidably connected. The outer surface of the fixed foot 402 is slidably connected to the inner wall of the extrusion port 202.

[0025] In this embodiment, a connection port 102 is provided for engaging with the mounting frame 201 and the combination frame 301. Both ends of the mounting frame 201 and the combination frame 301 are provided with a frame that engages with the connection port 102, thereby connecting the busbar trunking bodies 1 on both sides.

[0026] By setting the fixing component 4, the combination frame 301 and the mounting frame 201 are tightly attached to the top of the busbar trunking body 1 on both sides, wherein the surrounding frame 401 is attached to the surface of the combination frame 301.

[0027] There is an opening on one side of the extrusion port 202. The fixing foot 402 is placed into the extrusion port 202 through the opening using the surrounding frame 401. Then the surrounding frame 401 is slid to the other side. The fixing foot 402 is always in the extrusion port 202. Due to the slope of the extrusion port 202, the spring 405 will be stretched while the surrounding frame 401 is sliding. At the same time, the support rod 404 will slide outward from the support groove 407. The support rod 404 is used to support the stretching and contraction of the spring 405.

[0028] Additionally, the baffle 403 will move down with the fixing foot 402, but will always cover one side of the space between the surrounding frame 401 and the fixing foot 402, thus preventing the spring 405 from being exposed on the surface and accidentally damaged. The installation between the mounting frame 201 and the combination frame 301 can be completed when the fixing foot 402 is locked in the innermost pressing port 202. The innermost pressing port 202 and the outer surface of the fixing foot 402 are locked together to prevent the fixing foot 402 from being moved by the pulling force of the spring 405.

[0029] Example 2

[0030] like Figure 6 As shown, the outer surface of the combination frame 301 is provided with a fixing hole 302, the outer surface of the surrounding frame 401 is provided with a knob 408, the outer surface of the knob 408 is fixedly connected with a connecting post 409, the top of the surrounding frame 401 is provided with a round hole, the inner wall of the round hole is slidably connected with the inner wall of the connecting post 409, the bottom of the connecting post 409 is fixedly connected with a limiting foot 410, and the outer surface of the limiting foot 410 is slidably connected with the inner wall of the fixing hole 302.

[0031] In this embodiment, by setting a connecting post 409 for insertion into a circular hole, which extends from the surrounding frame 401 to the combination frame 301, the connecting post 409 is stuck in the circular hole, which can further prevent the fixing foot 402 from moving, thereby stably being stuck on the innermost side of the extrusion port 202.

[0032] By setting the limiting foot 410 and the fixing hole 302, the limiting foot 410 can be rotated and locked onto the inner wall of the combination frame 301 by the knob 408, so that the connecting column 409 will not come out of the round hole.

[0033] Working principle:

[0034] like Figure 1-6As shown, when connecting the two busbar trunking bodies 1, the two ends of the mounting frame 201 and the combination frame 301 are inserted into the connection ports 102 of the two busbar trunking bodies 1. Then, the clamping port 202 is enclosed by the surrounding frame 401, which places the fixing foot 402 into the clamping port 202 from the opening on one side. Then, the surrounding frame 401 is slid to the other side, and the fixing foot 402 remains in the clamping port 202. Due to the slope of the clamping port 202, the spring 405 is stretched while the surrounding frame 401 slides, and the support rod 404 slides outward from the support groove 407 at the same time. The support rod 404 is used to support the stretching and contraction of the spring 405. In addition, The baffle 403 will move down with the fixing foot 402, but will always cover one side of the space between the surrounding frame 401 and the fixing foot 402, thus preventing the spring 405 from being exposed on the surface and accidentally damaged; until the fixing foot 402 is locked in the innermost pressing port 202, the installation between the mounting frame 201 and the combination frame 301 can be completed, and the innermost pressing port 202 and the outer surface of the fixing foot 402 are locked together, preventing the fixing foot 402 from being moved by the pulling force of the spring 405; finally, the connecting post 409 is inserted into the round hole, and then the limiting foot 410 is rotated and locked in the inner wall of the combination frame 301 by the knob 408, so that the connecting post 409 will not come out of the round hole.

[0035] 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.
