Description

Technical Field

[0001] This utility model relates to the field of busbar trunking housing technology, and in particular to a busbar trunking housing made of high-strength material. Background Technology

[0002] In modern building power systems, industrial production lines, and large data centers, busbar trunking is a high-efficiency power transmission device. Its operational stability is crucial to the safety and efficiency of the power system. As the core protective structure, the busbar trunking shell needs to provide physical protection for the internal copper busbars, insulation components, etc., and has the structural strength to adapt to complex installation environments. In order to increase the structural strength of the shell, high-strength materials for busbar trunking shells have been widely used. Their structural strength far exceeds that of traditional ordinary cold-rolled steel plate shells, improving their impact resistance and deformation resistance.

[0003] However, existing busbar trunking shells made of high-strength materials mostly continue the traditional design in terms of installation and maintenance, still mainly using bolt-through connections. Due to the high hardness of the high-strength materials themselves, bolts are prone to stripping and locking during installation. Moreover, after long-term use, the contact surface between the bolts and the shell is prone to adhesion due to electrochemical corrosion, making disassembly and maintenance difficult in the later stages. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies. Existing busbar trunking shells made of high-strength materials mostly follow traditional designs in terms of installation and maintenance, still mainly relying on bolt-through connections. Due to the high hardness of the high-strength materials themselves, bolts are prone to stripping and locking during installation. Furthermore, after long-term use, the contact surface between the bolts and the shell is prone to adhesion due to electrochemical corrosion, leading to difficulties in later maintenance and disassembly. This utility model provides a busbar trunking shell made of high-strength materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a busbar trunking shell made of high-strength material, comprising a side shell, an upper closed shell provided at the top of the side shell, a positioning component provided on the outer surface of the upper closed shell, the positioning component comprising a trapezoidal snap-fit ​​plate, a positioning plate fixedly connected to the bottom of the trapezoidal snap-fit ​​plate, a fixing hole provided on the outer surface of the positioning plate, a rotating shaft rotatably connected to the top of the trapezoidal snap-fit ​​plate, a movable component rotatably connected to one side of the rotating shaft, the movable component comprising a rotating plate, a connecting plate fixedly connected to the bottom of the rotating plate, a sliding groove provided on one side of the connecting plate, a sliding plate slidably connected to the inner wall of the sliding groove, a fixing block fixedly connected to one side of the sliding plate, the outer surface of the fixing block slidably connected to the inner wall of the fixing hole, a support column fixedly connected to one side of the sliding plate, a spring provided on the outer surface of the support column, one end of the spring fixedly connected to the inner wall of the sliding groove.

[0006] In a preferred embodiment, the outer surface of the upper closed shell is provided with a positioning hole, and the inner wall of the positioning hole is slidably connected to the outer surface of the positioning plate.

[0007] In a preferred embodiment, the outer surface of the positioning plate is provided with a circular groove, and the inner wall of the circular groove is slidably connected to the outer surface of the support column.

[0008] In a preferred embodiment, the outer surface of the sliding plate is rotatably connected to a rotating column via a bearing, and the outer surface of the rotating column is provided with a threaded ring.

[0009] In one preferred embodiment, a knob is fixedly connected to one end of the rotating column.

[0010] In a preferred embodiment, the outer surface of the threaded ring is fixedly connected to the outer surface of the connecting plate through a threaded hole.

[0011] In a preferred embodiment, the inner wall of the sliding groove is provided with a threaded hole, and the inner wall of the threaded hole is slidably connected to the outer surface of the rotating column.

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

[0013] This utility model uses positioning components and movable parts to connect the side shell and the upper closed shell. The rotating shaft facilitates the upward flipping of the movable part, thus preventing the positioning component from being stuck in the positioning hole. The connecting plate can be flipped downward to fit against one side of the positioning plate. The spring facilitates the use of spring force to pull the fixing block into the fixing hole. The support column and circular groove are designed to prevent spring deformation and to make the fixing block more securely stuck in the fixing hole when the support column is stuck in the circular groove. The rotating column and knob facilitate the backward pulling of the fixing block by turning the knob, thereby disengaging it from the fixing hole and releasing the fixed connection at the connection point of the busbar trunking shell, making it easy to disassemble the busbar trunking shell. The threaded ring and threaded hole ensure that the threaded ring is screwed into the threaded hole, and the rotating column will not move under the tension of the spring, thus effectively preventing the spring from pulling the fixing block back into the fixing hole.

[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 1-4 As shown, this utility model provides a technical solution: a busbar trunking shell made of high-strength material, including a side shell 1, an upper closed shell 2 on the top of the side shell 1, a positioning member 3 on the outer surface of the upper closed shell 2, the positioning member 3 including a trapezoidal snap-fit ​​plate 31, a positioning plate 32 fixedly connected to the bottom of the trapezoidal snap-fit ​​plate 31, a fixing hole 33 on the outer surface of the positioning plate 32, a rotating shaft rotatably connected to the top of the trapezoidal snap-fit ​​plate 31, a movable component 4 rotatably connected to one side of the rotating shaft, the movable component 4 including a rotating plate 41, a connecting plate 42 fixedly connected to the bottom of the rotating plate 41, and a connecting plate 42 on one side of the connecting plate 42. A sliding groove 43 is provided, and a sliding plate 44 is slidably connected to the inner wall of the sliding groove 43. A fixing block 45 is fixedly connected to one side of the sliding plate 44. The outer surface of the fixing block 45 is slidably connected to the inner wall of the fixing hole 33. A support column 46 is fixedly connected to one side of the sliding plate 44. A spring 47 is provided on the outer surface of the support column 46. One end of the spring 47 is fixedly connected to the inner wall of the sliding groove 43. A positioning hole is provided on the outer surface of the upper closed shell 2. The inner wall of the positioning hole is slidably connected to the outer surface of the positioning plate 32. A circular groove is provided on the outer surface of the positioning plate 32. The inner wall of the circular groove is slidably connected to the outer surface of the support column 46.

[0025] In this embodiment, the positioning element 3 and the movable component 4 are used to connect the side shell 1 and the upper closed shell 2. The positioning hole and the positioning plate 32 are used for initial positioning. The trapezoidal snap-fit ​​plate 31, the rotating plate 41 and the connecting plate 42 can fit against the outer surface of the side shell 1 and the upper closed shell 2, making the installation more stable. The rotating shaft makes it easy to flip the movable component 4 upward, so as not to obstruct the positioning element 3 from being stuck in the positioning hole. The connecting plate 42 can fit against one side of the positioning plate 32 after being flipped downward. The spring 47 makes it easy to use the elastic force of the spring 47 to pull the fixing block 45 into the fixing hole 33. The support column 46 and the circular groove are provided to prevent the spring 47 from deforming and to make the fixing block 45 more stable when the support column 46 is stuck in the circular groove.

[0026] Example 2

[0027] like Figure 1-4 As shown, the outer surface of the sliding plate 44 is rotatably connected to the rotating column 48 via a bearing. The outer surface of the rotating column 48 is provided with a threaded ring 49. One end of the rotating column 48 is fixedly connected to a knob 410. The outer surface of the threaded ring 49 is fixedly connected to the outer surface of the connecting plate 42 via a threaded hole. The inner wall of the sliding groove 43 is provided with a threaded hole, and the inner wall of the threaded hole is slidably connected to the outer surface of the rotating column 48.

[0028] In this embodiment, the rotating column 48 and the knob 410 facilitate pulling the fixing block 45 backward through the knob 410, thereby disengaging it from the fixing hole 33, releasing the fixed connection at the connection point of the busbar trunking shell, and easily disassembling the busbar trunking shell. The threaded ring 49 and the threaded hole are designed so that when the rotating column 48 is pulled outward until the threaded ring 49 is stuck in the threaded hole, the knob 410 is rotated to screw the threaded ring 49 into the threaded hole, so that the rotating column 48 will not move under the tension of the spring 47, thus effectively preventing the spring 47 from pulling the fixing block 45 back into the fixing hole 33. During installation, the knob 410 is rotated in the opposite direction to move the threaded ring 49 into the sliding groove 43 and gradually disengage it from the threaded hole. The spring 47 then automatically resets and locks the fixing block 45 into the fixing hole 33.

[0029] Working principle:

[0030] like Figure 1-4 As shown, during the actual installation process, the positioning plate 32 is first aligned with the positioning hole on the outer surface of the upper closed shell 2 and inserted to achieve the initial positioning of the side shell 1 and the upper closed shell 2. Then, the movable component 4 is flipped down around the rotation axis so that the connecting plate 42 fits against the side of the positioning plate 32. At this time, the return force of the spring 47 pushes the sliding plate 44 to move along the sliding groove 43 toward the positioning plate 32, driving the fixing block 45 to be inserted into the fixing hole 33. At the same time, the support column 46 slides into the circular groove on the outer surface of the positioning plate 32 to form a double fixing structure to ensure connection stability.

[0031] When disassembly is required, rotating the knob 410 drives the rotating column 48 to rotate. After pulling outward a certain distance, the rotating column 48 is fixed in position after being pulled outward by the engagement of the threaded ring 49 and the threaded hole on the outer surface of the connecting plate 42. The sliding plate 44 stretches the spring 47 under the drive of the rotating column 48 and causes the fixing block 45 to disengage from the fixing hole 33. At this time, flipping the movable component 4 upward can release the locking between the positioning part 3 and the movable component 4, thereby separating the upper closed shell 2 from the side shell 1. This structural design achieves quick assembly and disassembly through mechanical cooperation, while the fit design of the trapezoidal snap plate 31 and the rotating plate 41 enhances the overall strength of the shell.

[0032] 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.
