[0003] After retrieval, the Chinese patent with the application number "CN202421194943.8" is specifically a high-voltage power transformer for enhancing the wire clamping strength. When in use, the excess lead wires can be wound around three threaded rods arranged on the surface of the support block, and then by turning the nut, the nut can move up and down on the threaded rod until the lead wires wound around the threaded rod are pressed and fixed.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] As Figure 1 - Figure 6 shown, an embodiment of the present invention provides a high-voltage power transformer for enhancing the clamping strength of wires, including a main body 1. A wiring post 7 and a mounting base 2 are fixedly connected to the front side of the main body 1. A protective cover 3 is arranged on the upper side of the mounting base 2. Mounting blocks 4 are fixedly connected to both the left and right sides of the protective cover 3. Through holes 5 are opened on both the left and right sides of the protective cover 3. A wire winding unit 6 for limiting the wires is arranged on the upper side of the mounting base 2. The wire winding unit 6 includes a fixing frame 61 fixedly connected to the upper side of the mounting base 2. A through ring 62 is fixedly connected to the lower side of the fixing frame 61. A limiting component 63 for limiting the wires and enabling quick disassembly is arranged on the upper side of the mounting base 2. Two wire winding posts 65 are fixedly connected to the upper side of the mounting base 2. The inner side of the mounting base 2 is a hollow structure. A stabilizing component 64 is arranged inside the mounting base 2. By providing the protective cover 3, it is convenient to protect the internal wires. When connecting the wires, through the wiring post 7, the wires are connected to the main body 1. The wires pass through the through ring 62, and then through the wire winding posts 65 on both sides, the wires are wound around the wire winding posts 65, which is convenient for limiting the wires.

[0030] The limiting component 63 includes two guide plates 636. The two guide plates 636 are fixedly connected to the upper side of the mounting base 2 and are located on the front and rear sides of the winding column 65. Guide blocks 637 are slidably connected to the outer sides of the guide plates 636 on the front and rear sides. Vertical plates 6314 are fixedly connected to the upper sides of the guide blocks 637 on the front and rear sides. A lifting groove 6315 is formed in the outer side of the vertical plate 6314. A lifting block 6316 is slidably connected to the inner side of the lifting groove 6315. A connecting block 6317 is fixedly connected to the side of the lifting block 6316 close to the winding column 65. Moving plates 631 are fixedly connected to the outer sides of the connecting blocks 6317 on the front and rear sides. A first moving rod 633 is arranged on the outer side of the moving plate 631. A limiting plate 632 is fixedly connected to the end of the first moving rod 633 close to the winding column 65. The other end of the first moving rod 633 passes through the outer side of the moving plate 631 and is fixedly connected to a moving block 634. A first spring 635 is fixedly connected between the moving block 634 and the moving plate 631. A first rotating block 638 is fixedly connected to the outer side of the guide block 637. Inclined plates 639 are rotatably connected to the outer sides of the first rotating blocks 638 on the front and rear sides. A second rotating block 6310 is rotatably connected to the outer side of the inclined plate 639. A first control block 6311 is fixedly connected to the outer side of the second rotating block 6310. Two first sliding grooves 6312 are formed in the upper side of the mounting base 2. First sliding blocks 6313 are slidably connected to the inner sides of the two first sliding grooves 6312. The first sliding blocks 6313 are fixedly connected to the first control block 6311. A control plate 6318 is fixedly connected to the other side of the lifting block 6316. A sliding rod 6319 is fixedly connected to the outer side of the control plate 6318. A plurality of side plates 6320 are fixedly connected to the upper side of the mounting base 2. An inclined groove 6321 is formed in the outer side of the side plate 6320. The sliding rod 6319 is slidably connected to the inclined groove 6321. The moving plates 631 and the limiting plates 632 are both arranged in an arc structure. When limiting the cable, rotate the turning cap 645. The turning cap 645 drives the bidirectional screw 644 to rotate. The bidirectional screw 644 drives the first sliding blocks 6313 on the left and right sides to move away. The first sliding blocks 6313 drive the first control block 6311 to move. The first control block 6311 drives the inclined plate 639 to rotate. Since the inclined plates 639 on the front and rear sides are symmetrically distributed, the guide blocks 637 on both sides approach each other. The guide blocks 637 drive the vertical plates 6314 to move. The vertical plates 6314 drive the moving plates 631 on the connecting blocks 6317 to move. The moving plates 631 drive the limiting plates 632 to move, so that the limiting plates 632 on the front and rear sides approach each other. At the same time, the control plate 6318 moves. The control plate 6318 drives the sliding rod 6319 to move. Since the sliding rod 6319 is slidably connected to the inclined groove 6321, the sliding rod 6319 drives the control plate 6318 to descend, so that the control plate 6318 drives the limiting plates 632 and the moving plates 631 to descend, and the limiting plates 632 and the moving plates 631 on both sides press down on the wound cable for limiting. When disassembling, rotate the bidirectional screw 644 in the reverse direction, so that the limiting plates 632 and the moving plates 631 rise when separated, which is convenient for quickly disassembling the cable wound around the winding column 65, and the operation is simple.

[0031] The stabilizing component 64 includes a second chute 641 which is opened on the upper side of the mounting base 2. Both inner sides of the left and right ends of the second chute 641 are slidably connected with second sliders 642. The upper side of the second slider 642 is fixedly connected with a top plate 646. The outer side of the top plate 646 is provided with a second moving rod 647. One end of the second moving rod 647 close to the wire winding column 65 is fixedly connected with a stabilizing plate 648. A second spring 649 is fixedly connected between the stabilizing plate 648 and the top plate 646. The lower sides of the first slider 6313 and the second slider 642 are fixedly connected with an L-shaped plate 643. The inner side of the mounting base 2 is rotatably connected with a bidirectional screw 644. Opposite threads are provided at both ends of the bidirectional screw 644. Both ends of the bidirectional screw 644 are respectively threadedly connected with the left and right first sliders 6313. The right end of the bidirectional screw 644 passes through the right side of the mounting base 2 and is fixedly connected with a turning cap 645. The stabilizing plate 648 is arranged in an arc structure. When limiting the cable, the two first sliders 6313 separate from each other. The first slider 6313 drives the L-shaped plate 643 to move. The L-shaped plate 643 drives the second slider 642 to move. The second slider 642 drives the top plate 646 to move. The top plate 646 drives the stabilizing plate 648 on the second moving rod 647 to approach the wire winding column 65, so that the stabilizing plate 648 limits the side of the cable, making the clamping effect of the cable better.

[0032] Working principle: When in use, first connect the cable to the terminal 7, then pass the cable through the through-ring 62, wind the cable around the wire winding column 65, and then rotate the turning cap 645 to control the rotation of the bidirectional screw 644, controlling the two first sliders 6313 to separate from each other. Under the action of the inclined plate 639, the guide block 637, the vertical plate 6314, the connecting block 6317, and the moving plate 631, control the front and rear limiting plates 632 to approach each other. At the same time, under the action of the control plate 6318, the sliding rod 6319, the inclined groove 6321, and the side plate 6320, control the limiting plate 632 and the moving plate 631 to descend, so that the limiting plate 632 and the moving plate 631 quickly limit the cable. At the same time, under the action of the L-shaped plate 643, the second slider 642, and the top plate 646, control the stabilizing plate 648 to limit the cable again, increasing the stability of clamping the cable. When disassembling, rotate the bidirectional screw 644 in the reverse direction, control the limiting plate 632 and the moving plate 631 to rise and separate, which is convenient for the staff to quickly disassemble the cable, and the operation is simple.
