Description

Technical Field

[0001] This utility model relates to the field of transformer technology, specifically to a lead wire support for a transformer. Background Art

[0002] Transformers are fundamental equipment for power transmission and distribution, and are widely used in industries, agriculture, transportation, urban communities, and other fields.

[0003] After the transformer is installed, the internal wiring harness needs to be led out from the top and pulled to connect with other external equipment. To ensure the safety of the wiring harness, it is usually necessary to fix the wiring harness to prevent it from falling. However, the current fixing method is mostly to shorten the excess length of the wiring harness and then fix it with a twisted piece. Although this method can achieve the purpose of fixing the wiring harness, it is not quick and convenient to adjust and maintain the wiring harness in subsequent use. It is necessary to disassemble and reinstall the twisted piece, which is cumbersome and inefficient.

[0004] Therefore, a lead bracket for transformers that is easy to adjust and maintain has been designed to address these shortcomings. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a lead wire bracket for transformers, which solves the problems of cumbersome lead wire fixing and inconvenience for subsequent maintenance and adjustment.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a lead wire support for a transformer, comprising a rectangular base frame, a horizontal sliding groove being provided at the bottom of the inner cavity of the rectangular base frame, a horizontal slider being slidably installed on the inner side of the horizontal sliding groove, and a plurality of horizontal sliders being provided, a vertical rotating rod being rotatably connected to the top of the horizontal slider through a bearing component, and a bent frame being fixedly connected to the top of the vertical rotating rod, a wire-passing groove being provided on the surface of the bent frame, and a first guide wheel being rotatably connected between the two sides of the inner cavity of the wire-passing groove through a bearing component.

[0007] Preferably, the front side of the bottom of the bending frame is connected to a threaded rod by an open thread, and the top end of the threaded rod extends to the upper part of the bending frame. The surface of the threaded rod and the upper part of the bending frame are threaded to an upper top frame, and a second guide wheel that cooperates with the first guide wheel is rotatably connected between the two sides of the inner cavity of the upper top frame through a bearing.

[0008] Preferably, the rear side of the top of the curved frame is provided with a vertical sliding groove that extends to the bottom, and an L-shaped sliding plate is slidably installed on the inner side of the vertical sliding groove, and the top of the L-shaped sliding plate is fixedly connected to the upper top frame.

[0009] Preferably, a limiting guide groove is provided on one side of the vertical rotating rod, extending to the other side, and a gear is slidably installed on the inner side of the limiting guide groove. The gear is sleeved on the surface of the vertical rotating rod, and the bottom end of the L-shaped sliding plate is fixedly connected to the top of the gear through a fixing block.

[0010] Preferably, the front and rear parts of the inner cavity of the rectangular bottom frame are both fixedly connected with tooth blocks for use with gears. Beneficial effects

[0011] This invention provides a lead wire support for a transformer. Compared with existing technologies, it has the following advantages:

[0012] (1) The lead bracket for the transformer has a bent frame installed on the inside of the rectangular base frame by means of a horizontal slider, and is used in conjunction with a vertical rotating rod and a second guide wheel. The structure allows for easy adjustment of the spacing between several bent frames during installation. At the same time, the orientation of the first guide wheel and the second guide wheel can be adjusted according to the direction of wire harness traction. Tightening the threaded rod allows the second guide wheel and the first guide wheel to clamp and fix the wire harness, improving the overall usability of the equipment and facilitating subsequent maintenance.

[0013] (2) The lead bracket for the transformer has an L-shaped sliding plate installed on the inner side of the vertical sliding groove, and the gear is connected to the upper frame by the L-shaped sliding plate. When the upper frame descends, the gear can mesh with the tooth block, thereby fixing the bending frame, the horizontal sliding block and the vertical rotating rod. This ensures the stability of the equipment during daily use, eliminates the need for complicated fixing methods, and improves the efficiency of installation. Attached Figure Description

[0022] In use, the rectangular base frame 1 is first installed on the surface of the transformer using bolts. Then, the threaded rod 8 is turned to push the top frame 9 up, causing the first guide wheel 7 to separate from the second guide wheel 10. At the same time, the L-shaped slide plate 12 pulls the gear 14 up on the surface of the vertical rotating rod 4 and finally separates from the tooth block 15. At this time, the horizontal slider 3 can be moved. The operator adjusts the spacing between several bending frames 5. After adjusting the spacing, the bending frame 5 is rotated using the vertical rotating rod 4 to adjust the direction and angle. After all adjustments are completed, the wire harness is passed through the inside of the wire groove 6 and placed on the inside of the first guide wheel 7. Then, the threaded rod 8 is rotated to drive the top frame 9 and the second guide wheel 10 to descend. After the second guide wheel 10 descends, it connects with the first guide wheel 7 to clamp and fix the wire harness.

[0023] Furthermore, a threaded rod 8 is connected to the front side of the bottom of the bending frame 5 by an open thread, and the top of the threaded rod 8 extends to the upper part of the bending frame 5. An upper top frame 9 is threadedly connected to the surface of the threaded rod 8 and located at the upper part of the bending frame 5.

A vertical sliding groove 11 extending through to the bottom is provided on the rear side of the top of the bending frame 5. An L-shaped sliding plate 12 is slidably installed on the inner side of the vertical sliding groove 11. The top of the L-shaped sliding plate 12 is fixedly connected to the upper top frame 9. A limiting guide groove 13 extending through to the other side is provided on one side of the vertical rotating rod 4. A gear 14 is slidably installed on the inner side of the limiting guide groove 13. The gear 14 is sleeved on the surface of the vertical rotating rod 4. The bottom end of the L-shaped sliding plate 12 is fixedly connected to the top of the gear 14 by a fixing block.

[0024] L-shaped slide plate 12 pushes cake gear 14 down to engage with tooth block 15. At this time, horizontal slide block 3 cannot move and vertical rotating rod 4 cannot rotate, thus fixing the equipment. Then the lead wire installation is completed.
