Description

Technical Field

[0001] This utility model relates to the field of busbar trough technology, and in particular to a retractable busbar trough. Background Technology

[0002] Busbar trunking is a closed metal device made of copper or aluminum busbar columns. It is used to distribute a large amount of power to various components in a distributed system. In indoor low-voltage power transmission trunk line projects, it has increasingly replaced wires and cables. During the use of busbars, busbar trunking is used to separate and install the busbars to protect them and reduce the possibility of damage during use.

[0003] Existing patent number CN222395415U discloses an adjustable telescopic busbar trunking, including a busbar trunking body. The top of the busbar trunking body is detachably equipped with a cover plate assembly. Symmetrical fixing blocks are provided on the outer end faces of both ends of the busbar trunking body. A plug-in groove is provided through the fixing block. A first fixing hole is provided on the fixing block and communicates with the plug-in groove, allowing a fixing bolt to be inserted. A docking groove is provided on the top end face of the fixing block. A first connecting hole is provided on the outer end face of the top of the fixing block and communicates with the docking groove, allowing a connecting bolt to be inserted. A receiving groove is symmetrically provided on the inner end faces of both ends of the busbar trunking body. A connecting block is provided on the inner side wall of the receiving groove. A busbar expansion joint is slidably connected in the receiving groove. The length of the busbar trunking body can be adjusted as needed, greatly improving the applicability of the busbar trunking body.

[0004] Using the above method, the busbars are installed through the mounting slots inside the protective plate. However, the dimensions of the mounting slots inside the protective plate are fixed, and only busbars of the same size can be installed. Otherwise, size mismatch will occur, causing the busbars to become loose and unstable, thus affecting the installation quality. Utility Model Content

[0005] The purpose of this utility model is to provide a retractable busbar trunking, which solves the problem found in the use of existing devices where busbars are installed through the mounting slot inside the protective plate. However, the size of the mounting slot inside the protective plate is fixed, and only busbars of the same size can be installed. Otherwise, size mismatch will occur, causing the busbars to become loose and unstable, thus affecting the installation quality.

[0006] To achieve the above objectives, this utility model provides a telescopic busbar trunking, including a telescopic mechanism and a protective plate, wherein the protective plate is disposed on the telescopic mechanism.

[0007] The device also includes a limiting mechanism, which comprises a limiting plate, a resisting plate, a limiting block, a moving block, a protective pad, a displacement component, and auxiliary components. The limiting block is slidably mounted on the protective plate, and the moving block is slidably mounted on the protective plate and symmetrically distributed with the limiting block. The limiting plate is fixedly mounted on the limiting block, the resisting plate is fixedly mounted on the moving block, the protective pad is detachably mounted on the limiting plate, the displacement component is disposed on the protective plate, and the auxiliary components are disposed on the protective plate.

[0008] The displacement assembly includes a rotating rod, a rotating disk, and a guide member. The rotating rod is threadedly connected to the moving block and the limiting block. The rotating disk is fixedly mounted on the rotating rod, and the guide member is disposed on the limiting plate.

[0009] The guide component includes a guide block, a positioning block, and a support component. The guide block is fixedly installed on the side of the limiting plate away from the limiting block. The positioning block is fixedly installed on the side of the resisting plate away from the moving block. The support component is disposed on the protective plate.

[0010] The supporting component includes a support rod and a crash pad. The support rod is slidably connected to the guide block and the positioning block, and the crash pad abuts against the positioning block.

[0011] The auxiliary components include a locking rod and a dustproof net. The locking rod abuts against the rotating rod, and the two ends of the dustproof net are fixedly connected to the moving block and the protective plate, respectively.

[0012] This utility model discloses a retractable busbar trunking system. A rotating disk drives a rotating rod to rotate, which in turn moves a limiting block and a moving block within a limiting groove on a protective plate. This movement of the limiting block and moving block, in turn, moves a limiting plate and a resisting plate, bringing them into contact with the busbar. Once the limiting plate and resisting plate are in position, a locking rod secures the rotating rod to the protective plate, thus limiting and fixing the busbar. This system meets the installation requirements of different sizes and solves the problem found in existing devices where busbar installation via internal mounting grooves on the protective plate is limited to a fixed size, resulting in size mismatch, loose busbars, and unstable installation, thus affecting installation quality.

[0023] This embodiment provides a retractable busbar trunking, including a telescopic mechanism 101, a protective plate 102, and a limiting mechanism. The limiting mechanism includes a limiting plate 103, a resisting plate 104, a limiting block 105, a moving block 106, a protective pad 107, a displacement component, and auxiliary components. The displacement component includes a rotating rod 108, a rotating disk 109, and a guide component. The guide component includes a guide block 110, a positioning block 111, and a support component. The support component includes a support rod 112 and an anti-collision pad 113. The auxiliary components include a locking rod 114 and a dustproof net 115. The aforementioned solution solves the problem found in the use of existing devices where busbars are installed through the mounting slot inside the protective plate 102. However, the mounting slot inside the protective plate 102 has a fixed size, which can only install busbars of the same size. Otherwise, size mismatch will occur, causing the busbars to become loose and unstable, thus affecting the installation quality.

[0024] In this embodiment, the protective plate 102 is mounted on the telescopic mechanism 101. The telescopic mechanism 101 includes existing mechanisms such as the busbar trunking body, busbar expansion joint, main cover plate, cover plate expansion joint, fixing bolts, connecting bolts, fastening bolts, and insulating fixing frame. This mechanism adopts the method described in the prior art, and adjusts the size of the mounting groove of the protective plate 102 by the limiting plate 103 and the resisting plate 104 to meet different size installation requirements.

[0025] The limiting block 105 is slidably mounted on the protective plate 102, the moving block 106 is slidably mounted on the protective plate 102 and symmetrically distributed with the limiting block 105, the limiting plate 103 is fixedly mounted on the limiting block 105, the resisting plate 104 is fixedly mounted on the moving block 106, the protective pad 107 is detachably mounted on the limiting plate 103, the displacement assembly is disposed on the protective plate 102, and the auxiliary component is disposed on the... The protective plate 102 has a limiting groove, and the limiting block 105 and the moving block 106 are located in the limiting groove. The limiting block 105 and the moving block 106 are in contact with the limiting groove and can move within the limiting groove. The resisting plate 104 has a protective pad 107 installed on the side near the limiting plate 103. The protective pad 107 is used to protect the busbar from direct contact with the limiting plate 103 and the resisting plate 104. The limiting plate 103 and the resisting plate 104 are located inside the protective plate 102, forming a placement groove between them for placing the busbar. In use, the busbar is first placed between the limiting plate 103 and the resisting plate 104. Then, the displacement component drives the limiting block 105 and the moving block 106 to move within the limiting groove of the protective plate 102. The movement of the limiting block 105 and the moving block 106 causes the limiting plate 103 and the resisting plate 104 to move, bringing them into contact with the busbar and thus limiting and fixing it. This satisfies different size installation requirements and solves the problem found in existing devices where busbar installation via the internal mounting groove of the protective plate 102 is limited to busbars of the same size, otherwise size mismatch will occur, causing the busbar to become loose and unstable, thus affecting installation quality.

[0026] Secondly, the rotating rod 108 is threadedly connected to the moving block 106 and the limiting block 105. The rotating disk 109 is fixedly installed on the rotating rod 108. The guide member is disposed on the limiting plate 103. The rotating rod 108 is rotatably installed on the protective plate 102. The rotating rod 108 has a bidirectional thread. The moving block 106 and the limiting block 105 have threaded holes that match the rotating rod 108. The rotating disk 109 drives the rotating rod 108 to rotate. The rotation of the rotating rod 108 drives the limiting block 105 and the moving block 106 to move within the limiting groove of the protective plate 102.

[0027] Furthermore, the guide block 110 is fixedly installed on the side of the limiting plate 103 away from the limiting block 105, and the positioning block 111 is fixedly installed on the side of the resisting plate 104 away from the moving block 106. The support component is disposed on the protective plate 102, and the protective plate 102 has a guide groove. The guide block 110 and the positioning block 111 are located in the guide groove. The limiting plate 103 and the resisting plate 104 are guided and positioned by the cooperation of the guide block 110 and the positioning block 111 with the guide groove.

[0028] Meanwhile, the support rod 112 is slidably connected to the guide block 110 and the positioning block 111, the anti-collision pad 113 abuts against the positioning block 111, the support rod 112 is fixedly installed on the protective plate 102, the guide block 110 and the positioning block 111 have sliding holes that match the support rod 112, the support rod 112 provides auxiliary support for the guide block 110 and the positioning block 111, and the anti-collision pad 113 prevents the positioning block 111 from impacting the protective plate 102.

[0029] In addition, the locking rod 114 abuts against the rotating rod 108, and the two ends of the dustproof net 115 are respectively fixedly connected to the moving block 106 and the protective plate 102. The protective plate 102 has a rotating hole that matches the rotating rod 108 and a locking hole that matches the locking rod 114. The locking hole communicates with the rotating hole. The dustproof net 115 prevents dust and impurities from entering the limiting groove. When the limiting plate 103 and the resisting plate 104 are adjusted to the correct position, the locking rod 114 resists and fixes the rotating rod 108 on the protective plate 102, thereby improving stability.

[0030] When using the retractable busbar trunking described in this embodiment, the rotating disk 109 drives the rotating rod 108 to rotate. The rotation of the rotating rod 108 drives the limiting block 105 and the moving block 106 to move within the limiting groove of the protective plate 102. The movement of the limiting block 105 and the moving block 106 drives the limiting plate 103 and the resisting plate 104 to move. The limiting plate 103 and the resisting plate 104 move and contact the busbar. When the limiting plate 103 and the resisting plate 104 are adjusted to the correct position, the locking rod 114 resists and fixes the rotating rod 108 on the protective plate 102, thereby limiting and fixing the busbar. This satisfies the installation requirements of different sizes and solves the problem found in the use of existing devices where the busbar is installed through the internal mounting groove of the protective plate 102. However, the internal mounting groove of the protective plate 102 has a fixed size, which can only install busbars of the same size. Otherwise, it will cause size mismatch, resulting in the busbar being loose and unstable, thus affecting the installation quality.

[0031] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
